Web 2. 0 technologies Essay Example for Free

Web 2. 0 technologies Essay The next portion of the interview focuses on the perception of students of being aware of this aspect. According to the results of the survey, 24 out of 6 educators are aware of students doing this. In addition to what was mentioned above, 20 out of 30 educators believe that this should be encouraged and 10 educators believe that this kind of technology should be separated from educational learning tools and should be solely for non-academic purposes. For the 20 that had expressed interest in encouraging Web 2. 0 applications into education, ten out of the 20 believe that it should be mandatory to all aspects of education and should be inserted into the academic curriculum. Five (5) believe that the utilization of Web 2. 0 technologies should be naturally included into the curriculum meaning that these tools should neither be constricted nor be pushed into utilization, rather it should be left to be incorporated into the curriculum all by itself. The last 5 indicated a variety of methods in order to encourage the use of Web 2. 0 technologies. When asked with the question on whether or not academic content should be delivered using Web 2. 0 technologies, 23 or 77% of the total number of respondents indicated that Web 2. 0 technologies would be a useful tool in delivering academic content from educators towards students. On the other hand, 13% (7 respondents) believed that it would be better to utilize the older, more accustomed, tools for information dissemination in order to project the desired image to the students and the stakeholders of the business venture. When asked if there is an existing overlap with the VLE that you used in the institution they are in, fifteen (15) out of the 30 indicated no recognized overlap, eight (8) indicated that there is no overlap while seven (7) believed that there is a overlap between Web 2. 0 technologies and the kind of VLE used. Because of the seeming trend with respect to the enthusiasm and openness of educators in using Web 2. 0 technologies, the next focus of the interview was set on Web 2. 0 tools being integrated with VLEs. Out of the thirty respondents, twenty-five (25) had indicated that they wanted to integrate VLEs with Web 2. 0 tools and five (5) had disagreed with the proposed integration. Most of the five (5) educators were from the seven people that believed there is an overlap between the two tools. The third part of the study focused on how they had perceived Web 2. 0 technologies as being part of the assessment process. The first part of the interview focused on Web 2. 0 technologies as part of the assessment purpose, the interview solicited how the interviewees perceived Web 2. 0 tools as an assessment tool. Generally speaking, most of the respondents to the interview indicated that they believe that currently, Web 2. 0 technologies used as a means of being able to assess is still very young rather it is still in its infancy stage. Though they believe that it would be step forward for the educational setting, there is still a need for further verification for such a move and should be tested if the students can adapt to such a change. Wikis was cited as one potential for teachers to evaluate the effectiveness of students in being able to collaborate with their partners in group work. Most of the educators indicated that they would rather evaluate students using the old method of educational teaching however they would be amenable of such as a move as to include Web 2. 0 applications into the curriculum and use it for checking and teaching. On the other hand, they had noted that it would be useful to check items in Web 2. 0 applications that are actually their cornerstone or the reason for their being – pictures in photoblogs such as flickr and video assignments in Youtube. When given the opportunity to explain very briefly each Web 2. 0 technology, the opinions of each educator as to how they can use these tools were solicited. For the first part of this section, blogs was the first application to be tackled. Based on the discussion, the educators generally indicated that they can utilize blogs as a mean of generating discussions among the students. With blogs having the capacity to take in comments and views via posting on certain topics, educators can then start up discussion on a particular topic and solicit the opinion of the class. Educators can then assess the views of the students by being able to review the comments of the students on that particular topic because of the capacity of blogs to retain inputs from users. The second tool is Wikis. Educators that were interviewed viewed wikis can be used in assessing the capability of the members in being able to collaborate and create singular information or a single document. This can then be used as a means of being able to assess how the students can cope with team effort and the output of such collaborative efforts. Social networks on the other hand can be used both by students and educators as well as a means to identify connections and networks that within communities that can be used by the students in order to determine people that have the necessary information for the teachings imposed by the students. Lastly, focus was given on video and photo sharing sites. Although this is relatively a new technology that would be used in sharing video and photo information between students, it is believed all these sites can be used in order to support all the learning motives for students and educators as well. Essentially the element of being able to share information particularly videos and photos is necessary are inherent in all sites. In addition to this, educators that were part of the group interviewed had already seen a video sharing site and they believe that due to the existing trends, video sharing networks will be able to further thrive and the educators believe that this will entail a positive effect on the way students are able to learn and how educators are able to teach.

Hispanic Discrimination In The US

Hispanic Discrimination In The US Introduction Hispanics are considered a single minority group arising in the United States which certainly as the name suggests being a product of the Spanish. It is evident that Spanish environment is dominated in such territories hence the high level of discrimination against them the American people are afraid of such small tribes to being very strong communities not only in politics but also power and economic development which directly poses a threat towards their growth as a nation. There are those intense factors that have facilitated discrimination of this community in the US, for instance Media presentations, Linguistic point of view and residence legality. As a result of this, the type of discrimination being embraced by this small community includes lack of proper health care, victims of hatred and oppression, lack of proper rental-housing and lack of health insurance. Catalyzing factors in racial discrimination Media and Hispanic oppression In every issue arising facing the human kind, the media is always there as a facility of creating awareness to the general public. Media can therefore be a very sensitive channel of communication and public awareness. With media broadcasting all the live events occurring in the general public, politicians and prominent people, there are very high chances of transmitting cases of hater speeches from different speakers which can bring forth tension among different people as a reaction, either positively or negatively(Cummins and Gordon, 2006). News broadcasting is considered to be a rapid-fire technique of delivering the real world in terms of cultural, economical and political issues. Some media stations tend to employ animation technology to portray sarcasm regarding a certain community hence creating the same expression in many of the viewers who later practice such actions but now in the real world and ends up hurting one another socially. With the media being interested mostly in transmitting the bad news for instance cases of illegal immigration being emphasized more upon as compared to the legal migration of the small communities particularly the Hispanic community as asserted by Lee (1998). This therefore reveals the role of media and the kind of information the media people transmitting the general public, which counts for negativity in most of the cases. News paper articles with very eye catching headlines such as illegal migrants, foreign drug dealers and such information is usually taken seriously and the initial blame befalls the small communities, with Hispanic being among the suspected group due to lack of proper understanding and like of love for one another. According to Lester(1996), the media is always very effective in framing issues since the initial intent is to give the public what they would like to hear, all about hate for the one not related with, for example the small community being blamed for each and every form of negative issues ari sing. Residency Illegality assumption In the United States, approximately more than 42 million legally migrated residents are believed to have Latin origin as noted in a statistical abstract (2007). About 16 million of these residents, an approximate of 39 percent, are born as foreigners. According to US immigration statistics, certain fraction, about 11 million people, of this population are estimated to have illegally migrated with 8.7 million migrants being believed to be of Hispanic origin as supported by Therrien and Ramirez (2001). This therefore asserts that more than 85 percent of Hispanic migrants have legally obtained their US residency with majority of them having been born in the United States. This therefore justifies the Hispanic community living in the United States from being discriminated against and they should hold their grounds while fighting for their residency rights, since by balancing the legal versus illegal migrants it clearly points the great difference favoring the legal migrants and the mere fraction that represents the illegal migrants should not earn such level of discrimination against the whole community. According to Jorgensen (1996), the US politicians are the leading people passing such complaints against what they term to be illegal aliens. Reports have proven that Hispanic employees have really experienced very unfair job mistreatment from their employers both in public and private sectors. Despite their hard work in jobs, no credit or appreciation is accorded to them for instance wages raise, no chances for ideas sharing since their ideas are considered unworthy towards bringing forth development. (Jennifer, 2007) Language barrier In the United States, there is a very strong bond connecting language and racism. The main group tends to discriminate the minority groups which certainly reflect on the hatred towards the Hispanics by the United States majority group (or rather the whites) residents. For instance the use of mal mot wetback is a clear example of sarcasm characterization used to classify the Hispanics who cross the Rio Grande boundary to the United States illegally. Now, the problem comes in where all the Hispanics suffer this oppression having legally or illegally migrated to the United States, hence being considered a high level of misunderstanding where even the innocent have to suffer on the account of the illegal migrants. The minority groups that cannot speak the dominant language are restricted from participating in the dominant culture and this has brought forth a two-side culture of living with those speaking native language (English) oppressing the alien language speakers for instance the Hi spanic community. The English language community has realized the linguistic threat posed by the Spanish language speakers in the United States since they seem to multiply as time passes on. As a reaction to this linguistic threat, native language heritage has started a campaign towards supporting English as the immediate language that should be embraced by each and every resident in the united states, being an American, Asian, Spanish or black American. With respect to this, a form of US bilingual education has been highly documented and debated about as asserted by Rothstein (1998). To many people, this form of education was more of a confusion situation than a solution, since each and every ethnic group concentrated in learning in their own language, but the English language conquering the rest, hence the alien natives being forced to embrace the English learning since they could not meet the standards to bring forth the level of education needed to code with the American way of learning. Effect of this discrimination Victims of hatred In the united states, majority of federal hate crimes target crime victims with respect to ethnicity or basic race initiated programs, according to the UCR (Uniform Crime Reporting)program, there is a huge number of hate speech white victims as compared to the other groups. According to research carried by New Century Foundation organization, it is worthy to claim that hate crimes towards the minority groups are committed mostly by the black Americans as compared to the white Americans. Among the minority groups, the Hispanics are more prone to being victims of hate speech. Referring to practical examples, quoting a previous case of racial hatred that took place back in the year 1992 whereby an Asian American and being of Chinese descent was beaten to death by an angry mob believed to be white assailants as a result of unemployment level hence blaming Japanese and Chinese US invasion. Women discrimination Hispanic Women in the United States are more exposed to discriminations compared to their male counterparts particularly when it comes to the job and labor sector. Female Hispanics wages do lag behind as compared to their fellow men colleagues it is evident that in the united states of America, the wages to Hispanic women are much less as compared to the white men, women and Hispanic men of the same level. According to a research carried out on the month of March back in the year 1998, it was known that males embracing Hispanic ethnicity earned an average of $ 11.75 in an hour whereas women earned an average of $ 9.40 for the same work type. White Non- Hispanic males and females earned on average $ 15.75 and $ 11.29 respectively. This difference in wages was claimed to have been as a result of education level, work experience, occupation type, language and lastly discrimination against women. According to Oaxaca (1973), Hispanic women wages discrimination is as a result of difference s from each individuals characteristics subtracted from the total wage required to be paid hence coming up with a new calculation factor which is more of corruption and somehow reflects to discrimination also. Health care inequality The government had failed to provide better health facilities plus other requirements towards ones good health for instance poor services, in adequate insurance, complete lack of health insurance and reluctance towards health seek and care (Woolf, 2004). Systematic bias is also reflected much in the way inequality is handled in health care while delivering health services to the Americans where personally I feel that these people are yet to be treated like rest of the Americans else such discrimination will bring a bad reputation towards the Americans in the near future. Though there are developments of anti-racism organizations for instance the National Association of the Advancement of Colored People, the Southern Poverty Law Center, the Anti-Defamation League, the Mexican American Legal Defense and Education Fund, American-Arab anti-Discrimination committee, the National Italian American Foundation and the National congress of American Indians among others. Sabotaged health conditions and deaths rate In the US, there is a wide range of racial differences in delivering health services appropriately. The migrants are treated in a negative way as compared to the US white residents. With reference to an article published by the public health sector in the US, it is worthy to assert that more than 880,000 deaths could have been avoided back in the year 1991 to 2000, if proper health care had been given to the foreign residents, inclusive of Hispanics. These deaths occurred as a result of much sabotaged health facilities given to the non-natives, if these people had received the same level of health services as the white Americans, such loss could not have occurred. It is worthy to claim that currently in the United States of America, racial bias has also infected the health sector with the minority communities facing very harsh condition due to low level of response from the health officers, particularly the public health sector. Referring to a previous study carried by Hope and Eliza beth (1996) it is evident that lifetime effects of fascinating conditions like being psych comes as a result of lack of attendance from the medic al officers to the patients who end up suffering some brain and mental conditions that could have been prevented in one way or the other given the issue of community discrimination support was avoided at all cost. It is believed that the minority communities cannot receive some donations for instance blood, and other body organs transplant from the American people which shows the level of discrimination being faced by these people and the importance of immediate reforms being embraced pertaining the same. Majority of Americans from these minority communities face inadequate insurance, poor medical services, and very low level of medical centers. Patients are forced to queue in some specific medical institutions that they can afford to pay rather than trying to scramble in a health facility where they are not welcome. Housing discrimination Despite of earning low income, the living standards of the Hispanics cannot be justified by such income. The poor housing conditions have left this community to face housing discrimination where high charges are given but with very minimal maintenances being employed whereby tenants suffer roofs leakages and rats become part and parcel of the house living. Some landlords go to the level of refusing to refund security deposit in the case where a Hispanic tenant wants to move in into another house. Such landlords also violate the US landlord-tenant laws that protects both the tenant and the landlord, for instance the 1998 Congress- passed Fair Housing Act which was meant to eradicate housing discrimination, but the landlords seem to be very mean with the lust for money but less worried with the housing conditions and its influence on the tenants. Most of the landlords practiced the following unlawful housing discrimination: Employing other forms of lease or contract provisions when dealing with Hispanics as compared to non-Hispanics. Having minimum maintenance and repair practices to the houses rented by the Hispanics which was not the case for the natives. Having minimal laundry and exercise facilities to the Hispanics which was not the case for the rest of tenants. Forcing Hispanics to provide very high security deposits as compared to non-Hispanics. Having the Hispanics evicted from the houses due to late payment of rent. Religion discrimination Today in the United States, when interviewed on how they feel about the status of their religious belief, 19 percent of Americans claim to consider being minority whereas 78 percent do not consider themselves being minority. This explains that 19 percent of the Americans are being discriminated against with respect to their religious beliefs. This has enhanced the prejudice by the Native Americans against other races as supported by Lincoln (2006). With US having the white evangelicals representing the highest percentage in terms of religion, about 24% of them refer themselves as constituent of the minority religious group whereas an equivalent of 11% of protestants and 13 % of Catholics claiming the same. Conclusion From this research, it is evident that Hispanics are being ill treated by the white in United States of America, courtesy of various published reports and scenes as discussed in the body of this research paper. The level of discrimination against Hispanic community living in the US is very serious with immediate measures worthy to be employed to counter it. From job discrimination, housing, freedom of expression, educational rights, and other rights have been denied to the Spanish residents living in the United States. Studies have found that nearly three in every ten Hispanic workers feel they have been discriminated against in their employment. Some reports being referred to with racial slurs at work while one in four feel they are paid less and have reduced career advancement prospects than their Caucasian counterparts( Sebastian, 1995). It is therefore the high time that Civil right Act, under the federal law that covers discrimination towards a particular race, color or sex comes into real action and performance. It is worthy to claim that the Hispanics have been deprived from their human rights to enjoying their freedom of expression, speech and movement. The non-governmental organizations enhancing campaigns against racial discrimination should also continue without fear or threat from authority or other people whatsoever. The Hispanic community should recognize their rights and carry a strict campaign against being discriminated. The local government should protect these minority communities from racial discrimination as a posed method towards enhancing well-being of each and every citizen.

Bad Odor and Bio-filtration Solutions

Bad Odor and Bio-filtration Solutions Mikhail Kachmazov UQ: How have microbes solved a local or global problem? The specific problem or issue: Sewage and industrial plants situated near residential areas can produce unpleasant odors making it difficult to live there. Explain the problem: The sewage plants near residential areas can be a subject to the social and environmental problems if these facilities produce unpleasant odors. The causes of the odors are generally the inorganic and volatile organic compounds which result from bio filtration and from the sewer of industrial waste. There are different types of volatile organic compounds that are emitted as a result of bio filtration like 2-butanone, ÃŽ ±-pinene, tetrachloroethylene, dimethyl disulfide, ÃŽ ²-pinene, limonene, phenol and benzoic acid. One of the main culprits for the bad odor are sulphur compounds which are relatively less in concentration but play significant role in odor causing factors.[5] Explain how science is helping, or has helped, to solve the problem: Bad odor from sewage water is a major environmental issue worldwide. Bad odor from sewage water is an indicator of possible health risk therefore governments spend a lot of money on treating the sewage water and unpleasant odor. Science has played a major role in solving this problem biologically as well as chemically. Following are several methods to treat sewage water and odor from this water. Bio filtration Thermal Oxidation Chemical Thermal oxidation burns the odor causing compounds directly or indirectly. Bio filtration on the other hand oxidizes the odor causing compounds by using microbes. Microbes like Pseudomonas Putida that are used in this technique have been significant in treating sewage water and bad odor in an efficient, safe and inexpensive way. [4] How it works: Bio-filtration is quite an innovative technology to control pollutants. It helps to eliminate malodorous gas emissions and volatile organic compounds (VOCs) of low concentrations. The most common design of a bio-filter is just an ordinary big box. Some of them can be very big, others can be quite small. A bio-filters main function is to bring microorganisms together with pollutants in an air stream. The bio-filter which has the breeding material for the microorganisms is placed inside the box. The â€Å"biofilm†, which is a layer of moisture where the microorganisms live, can be found around the particles of filter media. When the bio-filtration process takes place, the operators pump the polluted stream of air through the bio-filter, so that the filter media absorbs the pollutants. The bio-filter diffuses the contaminated gas and sends it onto the biofilm that absorbs it. The pollutants are then degraded by the microorganisms. The metabolic products of this process are carbon dioxide and water as well as the produced energy. The chemical formula of this process caused by oxidation is: Volatile Organic Pollutant + O2à ¯Ã†â€™Ã‚  CO2 + H2O + Heat + Microbial Biomass [3] Effectiveness of this technique: This technique is very efficient and it has plenty of advantages over the traditional methods of pollutants. First of all, one of the major conditions for traditional methods is high temperature, however when it comes to bio-filtration the technicians can use low temperatures, thus the whole process becomes cost effective, because there are no costs of combustion. Moreover it is safer than traditional methods because combustion is a dangerous process. Secondly, the maintenance cost of bio-filtration is much lower than traditional methods. According to a research conducted by Pinchin Environmental Group Canada, this technology is more than 95% efficient and environmentally friendly because the whole process can be done in an absolutely natural way. [1] Limitations of this technique: Even though this is an effective method it still has some limitations that restrict the implementation of this technique. First of all the bio-filtration is not able to remove all the organic substances from the water, for instance, those with low rates adsorption or degradation like chlorinated VOCs. Moreover this technique requires a large area to be installed in case it will need to treat a large amount of water. Finally, acclimation periods for populations of microbes may be as long as weeks or months, in particular for volatile organic compounds treatment. Applications of Bio-filtration: Even though the simple forms of bio-filters can be used by general public, the main uses are in the commercial areas. The following industries apply VOC: Chemical and petrochemical industry Synthetic resins Paint production Oil and gas industry Pharmaceutical industry Treatment of wastewater Remediation of Soil and Groundwater The following industries apply odor abatement applications: Treatment of sewage Slaughter houses Gelatin and glue plants Rendering Agricultural processing Tobacco, sugar and cocoa industry Fragrance and flavor Environmental, health and social impact: This technique is environmentally friendly because it does not damage the environment and it does not pollute the air or anything. It’s eco-friendly because the process is natural and does not harm the nature of the Earth, it is also been called a â€Å"green technology†. Moreover, it has positive health impact on the society, because the process of bio-filtration does not involve any chemical substances and does not produce any harmful chemical by-products. Basically, the only by-products of the process of oxidation used in bio-filtration are water and carbon dioxide, which makes this technology extremely clean and safe. Conclusion: To conclude I want to say that the bio-filtration process is an effective process that is used frequently nowadays. Even though it has its own limitations and disadvantages, still it is one of the most promising, environmentally friendly and efficient technologies, that combines both simplicity and effectiveness, therefore it is a viable alternative to traditional methods of sewage water treatment.

Coca-Cola :: essays research papers

Coca-Cola Company Analysis   Ã‚  Ã‚  Ã‚  Ã‚  The Coca-Cola company was founded in 1886 by John Pemberton, a Civil War veteran and Atlanta pharmacist. He was inspired by his curiosity as he stirred up a fragrant, caramel-colored liquid that he brought down to a place called Jacobs’ Pharmacy. There he added carbonated water and let several customers sample the new concoction. Jacobs’ Pharmacy put it on sale for five cents a glass and named it Coca-Cola. This â€Å"inspired curiosity† has now grown to be the world’s leading manufacturer, marketer, and distributor of nonalcoholic beverage concentrates and syrups. In 1906 Coca-Cola opened bottling plants in Canada, Cuba, and Panama. Today they produce nearly 400 brands in over 200 countries. More than 70% of their income comes from outside the U.S. (1). This paper will focus on an analysis of operations of the statement of cash flow reports and a vertical and horizontal analysis of the consolidated balance sheets. Also an analysis of t he global financial condition of the Coca-Cola Company and the value of goodwill and other intangible assets will be discussed.   Ã‚  Ã‚  Ã‚  Ã‚  The statement of cash flows reports a firm’s major cash inflows and outflows for a period. This statement provides useful information about a company’s ability to generate cash from operations, maintain and expand its operating capacity, meeting its financial obligations, and pay dividends. There are three types of activities to look at in this statement, which are cash flows from operating activities, investing activities, and financial activities (3, 2005). When analyzing Coca-Cola’s statement of cash flow, the first thing to note is a steady increase in operating activities within the past few years. These transactions affect the net income. From 2001 to 2003 the cash from net income increased from $4.1 million to $5.5 million. The operating activities is often the most important cash flow of a business because it shows the cash from revenue compared to the payments made for expenses (2). The cash flows from investing activities are cash flows from transactions that affect the investments in non-current assets. Some of these include investments in bottling companies; purchases of property, plant and equipment; and purchases of investments and assets. For the most part, these figures have remained fairly stable. From 2001 to 2003 it went from $1.1 million to $9.3 million, showing a slight decline (2). The last part of this report is the cash flow from financing activities.

Essay examples --

The word â€Å"challenging behavior† can evoke feelings of frustration, anger, hostility or sense of helplessness in any parent, teacher or caregiver of a young child with behavioral challenges. Education.com (2006 - 2012) defines this term: as behavior that may impede with a child’s ability to learn, develop or play in a manner that is socially acceptable. They further define challenging behavior as behavior that could be potentially harmful to the child or others. This type of behavior in a young child, predisposes that child to social problems and academic failure (Klass, Guskin, and Thomas, 1995; Ritchie and Pohl, 1995). Marion (2011) defines challenging behavior as a stimulus that a child reacts poorly to, that in turn challenges the child’s parents or teachers to guide them in a positive manner. Current research indicates that children who have significant challenging behavior will have problems in school. They have issues with social skills, emotiona l control and language development. These insufficiencies contribute to the lack of skills to succeed in basic academic tasks such as reading (Coi, 1996). Traits that are often attributed to children who exhibit these traits are hyperactivity, inattentiveness and disruptive. Teachers are twice as likely to overlook them, ask them fewer questions and be low in positive responsiveness (Webster-Stratton & Herbert, 1994; Shonkoff and Phillips, 2000). Children with behavioral challenges face far greater difficulties with social and emotional development. Other children will tease and ridicule them, or reject them entirely. These experiences bruise a child’s self-esteem and confidence, they are left feeling depressed and isolated. Once a child accepts rejection, they fight or ... ...s, to difficulties in conflict resolution to academic success. Parents play a pivotal role in teaching their young children how to appropriately behave or react to a certain stimuli. Positive adult-child interactions such as respect, providing an environment that is not rushed, using calm tones and accepting differences go a long way in changing or guiding a child’s behavior (Marion, 2011). For some children how to react to a certain situation in a positive manner is innate. However, other children need to be taught the skills to productively and successfully navigate conflicts that might arise. This can be achieved through a Direct Model Plan, a PBIS or a Behavior Matrix (Carter & Pool, 2012) The goal of challenging behaviors is to prevent those behaviors from rising, by providing children with the skills to navigate successfully through difficult situations.

Mine Sweeping System Using Image Processing

MINE SWEEPING SYSTEM USING IMAGE Processing Abstractions: Mine sweeping system is entirely designed for observing mines in peculiar user defined country. It uses a Java application from the user country and besides it consists of automaton which plays a cardinal function in the full system. The Java application and the automaton system works together to give an efficient system. The Java application is besides known as waiter and the automaton system communicate each other through wireless transmittal. In this system the human contact with the automaton is non required. The Java application is used to command the full mine sensing procedure. The optical flow vector, the automaton alliance and practical map of the location of the automatons are displayed on the screen of the waiter computing machine. Besides, the antecedently consequences that is the automatons that has searched for mines will besides be available or displayed for the user. So, that no demand of hunt for mines once more and once more in same country or practical grid. The ob tained database consequences are so uses to optimise thee mine brushing procedures in the hereafter through a LRU ( Least late used ) algorithm. The Robot system is aligned with a camera and uses a self-navigating algorithm with the obstruction turning away implemented utilizing optical flow. The optical flow which is produced within the milieus of the automaton system is registered utilizing the on board camera and by utilizing image processing methods like Image cleavage, Edge sensing and grouping, average filtrating thresholding procedure and by the vector computations, the hacking can be obtained. The automatons will work in a spontaneous practical grid and a existent clip map of the mine sweeping operation is displayed on the waiter system. Actually, the automatons will cipher the really shortest way within the grid while seeking and observing for the mines. The automatons commune with each other utilizing swarm engineering in order to carry through the undertaking. Introduction: The robotic usage of this mine sensing is a new procedure whereas the procedure of mine sensing is chiefly carried over by the worlds itself. They used to have on some protective cogwheel and some instruments with which they detect mines. There is a batch of hazard involved in this manner of mine sensing as no 1 can think the happening or the appendage of the blast. Hence so the usage of manual automatons in which they are guided by a user to observe or study a peculiar 1 for a mines therefore came into being. But these manner of observing mines was non much helpful as the manual navigate of the automaton of a certain country becomes tiresome largely over a big terrain. Therefore the demand for automatic automaton comes over when the user is non all required in voyaging the automaton. The robot hunt in a given country for the mines and the co-ordinates of their places are often sent to the waiter system. These automatons are plotted of a practical grid which is produced on the waiter system and their location can be tracked down. When a mine is detected the co-ordinate is sent back to the sever system and the symbol is marked on the practical grid denominating the sensing of mine such as co-ordinates, topographic point, clip, country all stored in the database. The user can so analyze the database to acquire the necessary information narrow down the hunt country. We used methods such as shortest way algorithm and chiefly image processing for obstruction turning away. Engagement of homo in the full sensing is non at all needed or zero. CONCEPTS AND FEATURES Optical flow Optical flow or ocular flow is the form of evident gesture of objects, surfaces and borders in a ocular scene caused by the comparative gesture between an perceiver and the scene [ 1 ] Optical flow computation utilizing Lucas cascade method The gesture of borders, surfaces and objects in a scene which raised by the gesture between an perceiver and scene is known as optical flow. The optical flow can be applied is obstacle turning away and self-alignment of driving circuit of the automaton. Calculation of optical flow Let us see two frames of clip T and a?† t at a place. The optical flow is calculated between this frames with the aid of a Taylor series method by utilizing partial derivation based on spacial and temporal coordnates. For a 2D+Tdimensional instance ( 3D orN-D instances are similar ) a voxel at locationwith strengthwill hold moved by,andbetween the two image frames, and the followersbrightness stability restraintcan be given: Assuming the motion to be little, the image restraint atwithTaylor seriescan be developed to acquire: H.O.T. From these equations it follows that: or which consequences in whereare theandconstituents of the speed or optical flow ofand,andare the derived functions of the image atin the corresponding waies.,andcan be written for the derived functions in the followers. Therefore: or [ 1 ] & A ; [ 2 ] This is an equation in two terra incognitas and can non be solved as such. This is known as theaperture problemof the optical flow algorithms. To happen the optical flow another set of equations is needed, given by some extra restraint. All optical flow methods introduce extra conditions for gauging the existent flow. In the mine sensing procedure optical flow is used for chiefly observing the object, hacking and besides for the robot pilotage. IMAGE SEGMENTATION Image cleavage is the procedure of partitioning a digital image into multiple sections which are sets of pels, besides known as ace pels. The end of cleavage is the simplify and/or alteration the representation of an image into something that is more pregnant full and easier to analyse. Image cleavage is typically used to turn up objects and boundaries which include lines, curves. In image more exactly image cleavage is the procedure of delegating a label to every pel in an image such that pels with the same label portion certain features. The basic measure for image retrieval by mercantile establishment is the computation of the ocular characteristics. The necessity to observe the object as a whole and non merely portion of it has been approved utilizing a intercrossed cleavage technique based on border sensing, part growth and optical flow processs. Image cleavage proves to be an of import measure in ciphering the navigational consequences of the automaton system. [ 1 ] & A ; [ 2 ] . Detection is based on object colour or strength contrast with the environing background. Regardless of the type of detector noise is ever present for cut downing these types of noises we use assorted types of filters. Median Filter Medium filter is a nonlinear method used to have noise from images. It is widely used as it is really effectual at taking noise while continuing borders. The average filter plants by traveling through the image pel by pel, replacing each value with the average value of vicinity pels. The form of neighbours is called the window, which pixel by pel over the full image. The median is calculated first screening all the pel values from the window into numerical over, and so replacing the pel being considered with the in-between pel value [ 3 ] Threshold Method It is besides known as image threshold. In this method, we introduce a new mechanism for observing the landmine. We merely convert the grayscale and cold images into binary or block/white images with specific threshold value or may be varies. Atmega 32 microcontroller The microcontroller we use in the mine sensing procedure for cryptography is the Atmega 32 which has characteristics such as.High public presentation, low power Atmel 8-bit micro accountantAdvanced RISC architecture133 powerful instructions- most signal clock rhythm executing32Ãâ€"8 general intent working registry + peripheral control registryFully inactive operation [ ]The microcontroller along with the L298 will be used to run the automaton automatically. Figure: Atmega 32 Microcontroller constellation Xbee pro communicating faculty The interaction between the automaton system and waiter system is formed through a Xbee faculty which acts as a trans receiver by procuring consecutive communicating utilizing the UART [ ] . Consecutive Communicationss The Xbee/Xbee-pro RF faculties interface to a host device through a logic – degree asynchronous consecutive port. Through its consecutive port the faculty can interact with any logic and electromotive force compatible VART ; or through a degree transcriber to any consecutive device. UART informations flow Devicess that have a vart interface can link straight to the pins of the RF faculty. Figure: UART environment Xbee pro system Flow Control DI ( Data In ) Buffer When the consecutive information enters RF faculty through the DI pin, the information is stood in the DI buffer until it can be processed. Hardware flow control ( CTS ) when the DI buffer is 17bytes off from being full ; by default, the faculty assert CTS to signal to the host device to halt directing informations CTS is re – asserted after the DI buffer has 34 bytes of memory available. Flow control DO ( Data Out ) When the RF information is received, the informations so enters the DO buffer and is sent out the consecutive point to a host device. Once the DO buffer reduces capacity, any extra entrance RF information is lost. Hardware flow control ( RTS ) : If RTs is enabled for flow control, informations will non be sent out the DO buffer every bit long as RTS is de- asserted. Therefore in this manner Xbee pro faculty questions to be an efficient trans receiver which initiates a 2nd VART channel. We create a templet foremost to carry through the papers processing demands. The others services will merely necessitate individual clip activation. SYSTEM DESIGN: The full mine sweeping system is categorized into three parts. They are:Waiter with Java ApplicationRobot system with drove engineeringWireless communicating system Figure: Block diagram system of Mine brushing Figure: Microcontroller and architecture communicating Figure: On Board camera and system communicatingWith the aid of net beans application the user controls the full system. At first the user writes a â€Å"start† bid in the Java application. Data will be send to the UART channel through wireless consecutive communicating.The start bid is received by the GB Xbee faculty on the automaton system and it triggers the micro accountant.After triping the micro accountant it invariably transmit a signal to the driving circuit with the aid of UART channel which portray the practical grid.The alterations are deciphered by the Java application and it was created on GEY at the same clip.This methodological analysis proceeds the circuit until the automaton achieves at the terminal of the self-created practical map.When the micro accountant is triggered it sends informations non merely to the drive circuit but besides to on board IP camera through a radio web device ( router ) to get down the image processing faculty.After triping of the IP c amera it captures the images of the practical grid and so it sends the information to the image processing faculty in which image cleavage optical flow consequences are generated.After finishing of the cringle the automaton sends a â€Å"stop† bid to the waiter.Software demands specification To put to death the mine sweeping system the user foremost enter the applicationThe automaton starts its procedure of seeking when it receives bid from the waiterThe automaton more over follows a optical flow which can be obtained by utilizing the on board IP camera. With the aid of optical flow method the automaton can avoid the obstructions and it itself align a practical map.The automaton so selects a shortest way on the practical grid to observe the mines.In this procedure the camera gaining control the image and the informations will be send to the image processing faculty in which mines can be detected by image cleavage procedure.After the image cleavage the information will be send to the waiter and shop in a information base.Here LRU algorithm is used to better the mine searching, observing and efficiency.Premises The distance between the client and the automaton should non be exceeded more than 500mtrs for good consequences. Dependences The connexion strength of UART is changeless. The automaton system must hold a changeless power supply all the times for accurate consequences. System characteristics The system consists of different characteristics to individual the operations. They are chiefly divided into: – Database Storage In this system this database storage plays a chief function. This storage system is used to hive away the images which was taken by on board camera. Here SQL database is developed and used to hive away consequences the automaton system and with the aid of JDBC connexion it was connected to java application Precedences With the aid of database the information will be stored manipulate and updated all the informations performed by the automaton is on the constituents. The illustrations are mine figure, location or country, count of mines etc. FunctionalRequirements The functional demands are nil but characteristics which are provided to stop users the full system has 3 bomber faculties they areJava application facultyImage processing facultyRobot facultyJava application faculty Java faculty is chief portion in the system from this lone the user starts the procedure by come ining the country of practical grid with this application we can besides see the full map with the aid of UART in which automaton performs operations. After finishing operations the applications shows the consequence for users java beans 7.0 is used to develop this application. Image processing faculty This faculty plays an of import key in the full system. By this the designation and localisation of mines was done. Here by utilizing image cleavage the mark is identified by the size form and visual aspect, this procedure is done by labelling procedure. In the image cleavage at first the gaining control image is labeled in to parts and so it converted in to black and white image so it subdivide the image harmonizing at that place sizes, forms and constructions. By utilizing these features the mark can be estimated of a mark assurance degree. Image cleavage is non sufficient for placing the mines so we use different mine field forms which can be find in survived part. Robot system faculty Thisconsists of micro accountant which generates the map and performs the operation when user gives a bid. Safety and Security RequirementsDue to connexion failures and micro accountant lapses the system may be crashed to over this state of affairs the robot resets and show approximately message to the user.The radio web is based on SSID user and watchword, which consists of unafraid connexion.ApplicationsIt consist of user friendly GUI.Known human contact is needed.All the communicating is through radio and web.The user can manually overrule the system.Conclusion The chief of the research is to develop a system which has a capableness of finding an object or mine. Here we used feeling techniques image cleavage and acknowledgment and faculties

Isaac Newton Is Better Than John Locke Essay

In all my life I have discovered many things. My discoveries have allowed us to make more new discoveries. But a problem I think of is what the world would be like if I never existed. To start things off one important discovery I made was modern physics. If I was never to make the discoveries in optics, motion, and mathematics modern physics wouldn’t of existed which means that scientist wouldn’t have never known that every object in the universe has a force that attracts each other. Something else the world would have never found would be my laws of motion. The laws of motion gave people a better understanding regarding movement which helps people today in space travel and mechanics. The world would be a better place without John Locke for many reasons. One good reason would be that if he didn’t exist there wouldn’t be a lot of abortion issues around the world and especially in the United States. The reason why there are a lot of abortion issues today in the United States is because John Locke influenced Thomas Jefferson and when Jefferson wrote the Declaration of Independence he included some stuff John Locke believed in. One thing was that he said human beings are free to do what they want with their property. There are good things about that but theirs also bad things like abortion. The reason why abortion is legal is because the baby are the parents property and John Locke said that when babies are in the stomach their blank so in other words babies are ok to be aborted because their nothing. So if john Locke was to never have existed he wouldn’t have been able to influence Thomas Jefferson which means that there wouldn’t have been a lot of abortions. To sum everything up I Isaac Newton has made the modern world a better place because of my discoveries and if John Locke never existed the world including the United States would have no abortion issues and remember all of us are here because we were all born and not aborted.
