On the other hand, team building enhances collaboration between all parties bound to the democratic style of leadership. Finally, communication provides a platform for effective and efficient flow of information. A combination of the three activities is a strategic approach towards improving democratic leadership. The above discussed activities are highly likely to foster personal and professional growth and development of all persons involved in democratic leadership. My vision, skills, traits, and background can essentially redesign and revolutionize future leadership. Whilst, democratic leadership entails active participation of group members or employees in decision making, the final say rests with the leader. In this respect, my vision, skills, traits, and background will play a vital role in coaching, mentoring, and supervising the people I will lead in

The Positive and Negative Effects of Technology Essay Example for Free

The Positive and Negative Effects of Technology Essay The use of technology has both positive and negative consequences. It is amazing how someone can find a long-lost friend through a social networking site, enabling them to reconnect. In a society where people have become quite mobile and family and friends are often geographically separated, it is convenient to keep in touch through technology. The positive side of technology is that you can use social networking to stay in touch with friends and family. Mobile phones are convenient for calling and texting those close to you as well as a useful tool for some online schools, playing games, taking and sharing pictures, searching the internet, accessing email and using your calendar to set appointments, reminders or events coming up. Some people believe that technology has a negative impact on others. One, social networking sites can be distracting, and could cause anxiety for the drama that is posted. Two, people use their mobile phones by texting others during working hours and get on the internet that is not related to their jobs and could be fired. Three, some parents and teachers think watching television can influence a child in a bad way which may cause their behavior to change. And finally, gaming presents linking to poor social skills and behavior.It is apparent that technology has the potential to harm or enhance your social skills and social life. In conclusion, technology today has come a long way. I believe, if used correctly, children and teens are monitored regularly, techonology can be very useful, entertaining and educational. The key is to analyze how technology affects you.

Understanding Of The Diversity Of Family Sociology Essay

Understanding Of The Diversity Of Family Sociology Essay The key family types are Nuclear, Extended, Reconstituted and Lone parent. These are the family types that exist in contemporary Britain. The basic premise is that the family structure depends upon social and economical circumstances as such family definition is open to cultural interpretation, norms and values. Whilst the family is adaptable-over the last Three hundred years in Britain, the family has changed and adapted, as we have moved from an agricultural society to industrial society. Sociologist George Peter Murdoch who defined the universal Family concept stated: The nuclear family is a universal human social grouping. Either as the sole prevailing form of the family or as the basic unit from which more complex forms compounded, it exists as a distinct and strongly functional group in every society The concept of the pre industrial extended family is somewhat of a misrepresentation when you consider death rates of working class families. The extended family is referred to as vertical extensions; Aunts, uncles, cousins and siblings -grandparents, children, and grandchildren who all live together, are referred to horizontal extensions the sexual relationships, and are monogamous within the extended and nuclear family. Polygamous relationships do exist within extended family, although this is predominately within specific cultures and religions. Examples being in the Moslem faith the act of polygamy are still practised; further more there are Christian sects such as the latter Day Saints who still practise polygamy, although such relationships are not legal within the European or American laws. The extended family can also be viewed as that of an extension to the nuclear family thru the inclusion of elders, such as grandparents, as many loan parents are female and they may well life or near their mothers, creating a matriarchal family extended unit. Extended reconstructed family, is considered to be when two opposite sex, or same sex adults with dependent children, either marry or cohabitate: thereby forming a reconstructed family over wise known as step families. Therefore it is not surprising that the most rapidly growing family type is that of the Reconstructed / stepfamily. Statistically most children stay with their mothers when their parents either divorce or separate so most children in a reconstructed family have step fathers this brings in to question the social as opposed to the biological care and nurture. It is quite common in British contemporary society for cohabitation of unmarried parents. The average is 31% of all parents as quoted (http://www.esrcsociet ytoday.ac.uk/ESRCInfoCentre/PO/releases/2004/june/stepfamilies.aspx) In contemporary society British society today Lone parenting is still predominately female orientated, however not exclusively as there has been a steady rise in men taking on the role of lone parenting estimates are that an average 11% of lone parents are now men. Attitudes in society have changed towards the lone parents. Nonetheless they are still passively ostracised from main stream society, by the media and government: as being less able, and a drain on society this is a view most commonly associated with conservatism as such in todays society the conservatives plan to introduce a tax that benefits the traditional stereo typical nuclear family which will effectively penalise both cohabiters and lone parents. www.telegraph.co.uk//conservative//Tories-5-billion-tax-breaks-for-married-couples-benefit-rich-most.html therefore in reality stigma still exists for lone parents. Single mothers were not socially acceptable in pre industrialised Britain, nor early industrialised any off spring were sent to childrens homes. There are notorious examples of how the mother and children were often treated, and can be found in Irelands History of Catholic unmarried mothers (http://www.catholicherald.co.uk/reviews/r0000523.shtml. Functionalists believed in a theory that the nuclear family is a positive social institution. Their view point is one of conservatism, which asserts it meets the needs of a contemporary industrial society. Functionalist emphasise that the ideal family type in modern society, is that of a traditional nuclear family. Their view of the nuclear family comprises of a worker husband and stay at home wife and 2.4 children. US sociologists have developed this approach, in particular Murdock, Parsons and Goode. The functional perspective on the family identifies a number of functions families will characteristically carry out: reproduction, socialisation, nurture, family hierarchy and family emotional support. Talcott Parson was a leading American sociologist in the 1950s who believed that the family was structured on the stabilisation of the adult family members and the socialisation of children. Based on a series of complex social structures and roles that needed to be adhered to achieve maximum family, social and cultural gratification -The social system consists of three systems a personality system, a cultural system and a physical environment to which the individual and society must adjust. Parsons model of key systems and sub systems further developed to define four functional prerequisites these are adaptation, to a physical environment, goal attainment, the ability to manage one self and resources to achieve its goals and obtain gratification, integration, the ability to form skills and ways to deal with differences and finally latency to achieve comparative stability. Each system consequently develops four specialist subsystems to be able to meet these mental and physical requir ements. There four systems are cultural, social, personality and biological- these systems are further broken down to four subsystems, these being (in hierarchical order) the socialisation system, the institutions of social control and integration, the political system goal attainment and the economic system adaptation. The feminist view on family is diverse, as the feminist school of thought has many layers from the liberal to the radical each having very different perspectives on family and the impact of family on woman, family and society. In general all feminists have been critical of the effects of family life on women however these views are dramatically different if not diametrically opposed. Liberal feminists reject the concept that family lives are reflections of the economic structure of society. They believe that the cultural and social aspects of male/female inequality are central to an understanding of the feminist issues. It is fair to say that most feminists believe that the family unit oppresses women and keeps men in power. This is based on the belief that society is patriarchical (male dominated) Patriarchy is defined as the combination of ideologies, cultural practices and systems which keep men in power. The three types of feminism liberal, Radical and Marxist aim to challenge patriarchy in different ways: Liberal feminists believe that the family is in essence institutionalised sexism, because its supports the mainstream culture which is also sexist. They advocate change through legislation and education. Jennifer Somerville a Liberal feminist http://soc.sagepub.com/cgi/content/abstract/31/4/673 asserts that the Radical and Marxist feminist have failed to take in to the account the changes in society that have enabled woman to enter the work force as equals to men, nor the social changes that removed the restrictions on females, such as child care, and the running of the home have changed. Men in society today, are far more likely be involved in the care and nurturing of their respective children and many men now enjoy the shared responsibility of caring for the child and home. The man is no longer elevated to the head of the house; as such equality in the home and family is being achieved. The Radical Feminist Kate Millett (Sexual Politics, 1971 argued that Sociology examines the status quo, calls it phenomena, and pretends to take no stand on it, thereby avoiding the necessity to comment on the invidious character of the relationship between the sex groups it studies. Yet by slow degrees of converting statistic to fact, function to prescription, bias to biology (or some other indeterminate) it comes to ratify and rationalise what has been socially enjoined or imposed into what is and ought to be. And through its pose of objectivity, it gains a special efficacy in reinforcing stereotypesFunctionalists, like other reactionaries, are out to save the family. Radical feminists view the family and men as the enemy within, which is both insidious and damaging to woman. Radical feminists believe that patriarchy is the central starting place of division in society. Essentially men exploit women as husbands, partners, sons and brothers. This manipulative relationship is reflect ed in the family; in which women do all the work for the benefit of men thus reinforcing the capitalist bourgeois ideology. Men are viewed as the enemy by radical feminists who have created a divide within the feminist ranks, as they believe that no female should be dominated or controlled, and the only way to achieve this, is to not participate in any sexual relationship with men. Valerie Bryson (1992) who bases her feminist philosophy as Marxist, argues all radical feminists see the oppression of women as the most fundamental and universal form of domination whilst this view is polarised within radical feminist thinking, it cannot be seen as definitive or even based in the feminist combined ideology. The Marxist feminist perspective argues that the principle source of division in society is class therefore the exploitation of women is indispensable to the continuation of capitalism The family produces and nurtures the next generation of workers at no cost obvious cost to the capitalists system woman doing housework is an unpaid role, which benefits the capitalist, woman were also viewed as cheap labour, before the equality laws were originally implemented in Britain in 19 75 which has gone thru many iterations, and the latest sexual equality act http://www.communities.gov.uk/documents/corporate/pdf/equalityimpactassessment.pdf was published in 2007. The earliest view of the family developed from a Marxist perspective is contained in Friedrich Engelss The Origin of the Family, Private Property and the State (Engels, 1972, first Published 1884) Engels stated that: The monogamous bourgeois nuclear family developed to help solve the problem of the inheritance of private property men needed to know who their children were in order to pass on their property to their heirs .The family is therefore designed to control women and protect property Freindrich Engles views the nuclear family as a creation of capitalism, specifically designed as patriachical, its primary purpose is to ensure and perpetuate male domination and power through the male only inheritance of land and property It therefore served the interests of capitalism to keep woman economically and socially of less value to society than men. The Marxist feminist view the tasks carried out by woman as reaffirming male dominance therefore house work, child care, cooking and emotional support are seen as detrimental to woman. Women also provide the sexual and emotional support to the husband or partner, in doing so the role is seen as one of submission to the hierarchy of the male head of family. Christine Delphy and Diana Leonard described the everyday situation of family as familiar exploitation however every example could be seen as simply supportive and part of a loving relationship. Todays family in contemporary Britain is made up of different family groups, cultures, ethnicity, class and economic status. There are more isolated nuclear families, which have either migrated to Britain, or moved geographically within Britain families who will have their own norms and values, based on cultural, religious, class or economics which they will bring with them, and incorporate in to their new life. Lone parents who work, as well as mothers from the traditional nuclear families who work, as a financial necessity or a career option. Same sex parents, who now have the same marriage and parenting rights as heterosexual parents. More people live together before marriage, children born outside marriage; all of these are now norms and values socially and culturally. Family and the definition of whats constitutes family and who actually benefits from the family has not changed. We create life and then teach our children. Families provide the care and nurturing essential to th e learning of who we are, and where we form, what has changed is the is open to personal need and interpretation. Essentially the choices of how family is defined are to fluid in their nature and to diverse, to be able to any other than a personal preference of how to live. Nor should government or society be so prescriptive and controlling to impose. In reviewing the different family types, mainly all have positives and negatives however when reviewing Murdochs assertion that every society had a form of the nuclear family , this was incorrect, as both Nayar and Kibbutz proved that the function of family can be performed equally in a society other than the western defined confines of the nuclear family structure. Different cultures, values and norms, create variations of family and also place different importance on the family status in society. In todays society we have many variations of family, same sex families, same sex lone parents, and same sex adoption. As such the traditional term of family is used incorrectly as an outdated social ideal. The world has changed and the attitudes to parenting specifically in Britain have changed. There have been several significant social developments which have brought about changes in social norms and values. The supporters of the nuclear family believe the benefits of the nuclear family are its conservative core norms, and values which underpin the moral, wellbeing of society. They also consider anything else as a failed form of the nuclear family. The traditional roles of men as the breadwinner, and woman as the happy and fulfilled house wife, staying at home, looking after the children is the theme they most project. The Media use this image of happy family relationship, between all ages groups, every day in concepts and products, actively promoting the nuclear family as the social aspiration to happiness, success and fulfilment- the paradox is that in reality many mothers and fathers in todays society, have no choice, because it not a financially viable option, as they would not be able to house or support their selves or their child/children with just one salary. Moreover the woman may be the chief breadwinner, and the husband would then have to embrace role reversal in the nuclear f amily and be a stay at home dad there has been an increase in men staying at home to fulfil the role of house husband, however it is still predominately a female responsibility to care for or arrange alternative care, for children in the nuclear family. The pre industrialised class and economic status had a significant effect on who lived or died an example being if the family was wealthy a land owner, they may well have a more favourable environment in which to increase their chances of survival, although they were still affected by such diseases as the Black Death (Yesinia pestis ) which over a period of two years killed between 30-40% of the entire population of England in both 1348 and 1605. Twice as many poor children died as rich children; the poor in the country were at the mercy of poor harvests, bad weather famine and infections. Also fatalities were higher in the towns where sanitation and overcrowding in poor areas encouraged the spread of the virus. Given that the pre industrial pre-plague population of England was in the range of 5-6 million people, fatalities may well have exceeded or reached as high as 2 million. Urbanisation or isolation neither could supply the basic needs of the poor, so its unlikely that any chi ld surviving the age of sixteen had an extended family, due to the circumstances that they were born in too. Their functionalist view of the family is ideological and unrealistic, as it does not represent a reality of ever changing family, cultural, economical and demographic factors of life and work If nothing else the functionalist view can be seen as a plausible aspiration for some conservative idealists it is however not a viable option for all family types. Equally from a Marxist perspective, the fact that its wrapped in gender and equality issues and that the feminists have such diverse diametrically viewpoints yet have also provided the vehicle for such positives changes in womens rights and social equality, it has to be held up as the champion of woman, yet also recognised as having done its job. Over the last 100 years in England, woman from all classes, ethnicity and culture have gained the right to vote; in the last 50 years working class woman gained entry to university, the right to divorce, and the right to birth control. These changes have impacted society to its very cor e; challenging the definition of the nuclear family and the society it fits into. Religion is slower to change its views on the Nuclear and industrial vision of the nuclear family: for instance where the Catholic Church is politically, ideologically and (possibly) economically powerful, the promotion of marriage, and the ban on contraception have significant consequences for the family, in terms of such things as: size, domestic violence, traditional male/female roles. This ensures the women are still disenfranchised and that emancipation of woman still exists in contemporary modern society. In todays society family is a hot topic. In last 60 years, there has been significant social and cultural change. There is however multiple issues as the pace of change has not be controlled or understood before being implemented. In conclusion its difficult to blithely wrap family in to one perspective, the reality is that there is no ideal family unit and common sense, pragmatism, social, cultural and economical factors must all be taken in to consideration. The western capitalist perspective of the nuclear family, extended family, same sex family or lone parent, do not necessarily translate to other cultures or societies. Equally the views of the feminists do not agree on female equality, or the emancipation and disenfranchisement of woman in todays society. Young girls and boys nurtured by their parents will determine the values and norms relating to their roles in latter life. Woman do have self determination in Britain today this provides the choices necessary on how they live their lives, be that in a nuclear family, in a same sex relationship or as a lone parent. If is impossible to make a definitive choice, as what benefits to the family as a whole, is to provide equal partnership, respect for both genders and a secure loving environment- in saying that domestic violence, drugs alcohol could all present as negatives. The liberal feminist stance resonant as the most pragmatic and balanced view whilst the radicals and Marxist feminist views are polarised in a gender war.

The Downfall of Macbeth :: essays research papers

Macbeth's love for Lady Macbeth, in William Shakespeare's tragedy Macbeth, caused Macbeth to feel the need to prove his manhood, which eventually lead to his downfall. Macbeth was not secure in his manhood, so he felt the need to prove himself to Lady Macbeth. After he proved he was a man by killing Duncan, and he felt he had a lot of power to do whatever he wanted. Macbeth became desensitized between all the killing and the hype of being the King. In the beginning of the play Macbeth showed his love for Lady Macbeth in many different ways. He told her his feelings toward her "My dearest love" (act I, scene v, l 58). Macbeth listens to what Lady Macbeth has to say, and takes her advice into consideration every time he makes a decision. He also has great love for her and tries his best to make her happy no matter what it takes. Then Lady Macbeth convinced Macbeth that he wasn't a man unless he went through with the murder of Duncan. She threatens his manhood by saying "When you durst do it, then you were a man;/ And to be more than what you were, you would/ Be so much more the man" (act I, scene vii, l 49-51). This made Macbeth begin to think, and slowly but surely Lady Macbeth had manipulated his mind to think the right thing to do was kill Duncan. Macbeth had decided in order to prove his manhood he must go through with this horrible act. Barta 2 After Macbeth had committed the crime he felt that his soul could never be cleansed no matter what he did. He said "They pluck out mine own eyes!/Will all great Neptune's ocean wash this blood/Clean from my hand? No; this my hand will rather/The Multitudinous seas incarnadine, /Making the green one red" (act II, scene iii, l 58-62). This shows that he really didn't want to kill Duncan, but he did it in order to prove himself to Lady Macbeth, and to become the king. By the end he had no fear, and had killed not only Duncan but also many other people. He now had different views from which he had in the beginning of the play. Macbeth realizes that he is no longer afraid "no, nor more fearful. (Act V, scene vii, l 9). He is now considered a man, but he doesn't like the fact that he has killed all these people.

Qualitative Analysis Essay

Qualitative is where the results give a colour that you have to match up to a colour chart, or have you have done to see if it is positive or negative with a description of what a positive reaction should look like. This test is less reliable as some colour or positive reaction look similar to each other or the same but by adding different chemicals. An example of qualitative would be a pH test as the result gives you a colour and then you have to match it up to the pH scale to get you final result. Qualitative analysis is used to find out different ion in a given sample. This also analytical chemistry technique, this testing method uses many different tests to get a reaction that would link with different ions. Ions An Ion is an electrically charged particles that are formed when atoms are added or taken way. Metal atoms have positively charged ions and non-metal atoms have negatively charged ions. To work out how many ions a metal and non-metal should have is simple. Metals should have the same amount of charged ions as the group number they are in for example a metal in group 2 will have two positively charged ions. Non-metals should have the same amount of charged ions as the group number they are in but minus eight for example a non-metal in group 5 would have 3 negatively charged ions. Negative ions are called anions and positive ions are called cations. When testing for cations/metals you could use a flame test this is the simplest and quickest way of test for cations another way that you could test for cations is a sodium hydroxide test this test consist of adding sodium hydroxide to test compound when coloured precipitate is formed them stop adding the sodium hydroxide and see what the cation is by using the table below, this table show what colour the precipitate is and any further results.

Optical Camouflage

OPTICAL CAMOUFLAGE ABSTRACT: The advancement in science is making what we may have thought of as impossible, probable. Humans may become invisible as the extra terrestrials which are considered to be probably invisible. A new technology provides a way to this. In this paper a scientific technology that is used to implement this idea is presented. The optical camouflage technology is one of the famous scientific technologies which helps in the invention of a new type of cloak called the invisible cloak. This is one of the big revolutions created in the area of virtual reality.It is just a concept of reflection of light by the cloak. The person who wears this cloak will feel as just what he feels with the ordinary cloaks but the person will be invisible to the outside environment. This is the main advantage of this cloak. There are many other interesting features present in this paper about this cloak. CHAPTER 1 : INTRODUCTION: Chaitanya Institute of Engineering & Technology Page 1 OPT ICAL CAMOUFLAGE Although optical is a term that technically refers to all forms of light, most proposed forms of optical camouflage would only provide invisibility in the visible portion of the spectrum.The research on the concept of invisibility was started in 1977 and was very successfully accomplished in 2003. Initially Professor Tachi from the University of Tokyo said that he had first had the idea of developing something to make objects invisible in 1977. But the imag e was flat and unrealistic. He came up with retro-reflective material which causes the coat to act as a screen and gives a transparent – or invisible – effect. Similarly, Duke University is using microwave beam deflection, making it appear almost as if nothing were there at all. If you’ve seen the movie â€Å"Harry Potter† then you may recognize the idea of an invisibility cloak. CHAPTER 2 : OPTICAL CAMOUFLAGE: Optical camouflage is a hypothetical type of active camouflage currently onl y in a very primitive stage of development. The idea is relatively straightforward: to create the illusion of invisibility by covering an object with something that projects the scene directly behind that Chaitanya Institute of Engineering & Technology Page 2 OPTICAL CAMOUFLAGE object. Optical camouflage is a kind of active camouflage which completely envelopes the wearer.It displays an image of the scene on the side opposite the viewer on it, so that the viewer can â€Å"see through† the wearer, rendering the wearer invisible. Although optical is a term that technically refers to all forms of light, most proposed forms of optical camouflage would only provide invisibility in the visible portion of the spectrum. Prototype examples and proposed designs of optical camouflage devices range back to the late eighties at least, and the concept began to appear in fiction in the late nineties. CHAPTER 2. 1 : Components of the Optical Camouflage:Optical camouflage doesn't work by way of magic. It works by taking advantage of something called augmented-reality technology. Augmented-reality systems add computergenerated information to a user's sensory perceptions. Most augmented-reality systems require that users look through a special viewing apparatus to see a real-world scene enhanced with synthesized graphics. They also require a powerful computer. Optical camouflage requires these things, as well, but it also requires several other components. ? A garment made from highly reflective material A video camera ? A computer ? A projector ? A special, half-silvered mirror called a combiner; which is the viewing screen CHAPTER 2. 2 : The Cloak: Chaitanya Institute of Engineering & Technology Page 3 OPTICAL CAMOUFLAGE It is made up of retro-reflective material. It has an observer that receives more of the reflected light and therefore sees a brighter reflection. It can be seen far away and outside in bright sunlight. CHAPTER 2. 3 : Other components: †¢ The camer a captures the digital video behind the person with the cloak. †¢The computer synthesizes the graphics and superimposes them on a real-world image. †¢ The projector shines a light beam through an opening controlled by a device called an iris diaphragm. †¢ The combiner (special mirror) is used to both reflect the projected image toward the cloak and let light rays bouncing off the cloak to return to the viewer’s eye. Chaitanya Institute of Engineering & Technology Page 4 OPTICAL CAMOUFLAGE CHAPTER 3 : CONCEPT OF INVISIBILITY CLOAK: Chaitanya Institute of Engineering & Technology Page 5 OPTICAL CAMOUFLAGE 1.The cloak that enables optical camouflage to work is made from a special material known as retro-reflective material. 2. A retro-reflective material is covered with thousands and thousands of small beads. When light strikes one of these beads, the light rays bounce back exactly in the same direction from which they came. 3. To understand why this is unique, lo ok at how light reflects off of other types of surfaces. A rough surface creates a diffused reflection because the incident (incoming) light rays get scattered in many different directions.A perfectly smooth surface, like that of a mirror, creates what is known as a specular reflection — a reflection in which incident light rays and reflected light rays form the exact same angle with the mirror surface. In retroreflection, the glass beads act like prisms, bending the light rays by a process known as refraction. This causes the reflected light rays to travel back along the same path as the incident light rays. The result: An observer situated at the light source receives more of the reflected light and therefore sees a brighter reflection.Chaitanya Institute of Engineering & Technology Page 6 OPTICAL CAMOUFLAGE CHAPTER 4 : WORKING: Chaitanya Institute of Engineering & Technology Page 7 OPTICAL CAMOUFLAGE Once a person puts on the cloak made with the retro-reflective material, here's the sequence of events: †¢ A digital video camera captures the scene behind the person wearing the cloak. †¢ The computer processes the captured image and makes the calculations necessary to adjust the still image or video so it will look realistic when it is projected. The projector receives the enhanced image from the computer and shines the image through a pinhole-sized opening onto the combiner. †¢ The silvered half of the mirror, which is completely reflective, bounces the projected image toward the person wearing the cloak. Chaitanya Institute of Engineering & Technology Page 8 OPTICAL CAMOUFLAGE †¢ The cloak acts like a movie screen, reflecting light directly back to the source, which in this case is the mirror. †¢ Light rays bouncing off of the cloak pass through the transparent part of the mirror and fall on the user's eyes.Remember that the light rays bouncing off of the cloak contain the image of the scene that exists behind the person wear ing the cloak. †¢ The person wearing the cloak appears invisible because the background scene is being displayed onto the retro-reflective material. At the same time, light rays from the rest of the world are allowed reach the user's eyes, making it seem as if an invisible person exists in an otherwise normal-looking world. CHAPTER 4. 1 : Key Challenges: †¢ Practicality smaller computer integrated replacement of projector combiner. †¢ Purchase patent or license. †¢High costs. †¢ Very small cameras and projectors CHAPTER 5 : MUTUAL TELEXISTENCE: Chaitanya Institute of Engineering & Technology Page 9 OPTICAL CAMOUFLAGE CHAPTER 5. 1 :How mutual telexistence works: Chaitanya Institute of Engineering & Technology Page 10 OPTICAL CAMOUFLAGE †¢ Human user A is at one location while his telexistence robot A is at another location with human user B. †¢ Human user B is at one location while his telexistence robot B is at another location with human user A. à ¢â‚¬ ¢ Both telexistence robots are covered in retro-reflective material so that they act like screens. With video cameras and projectors at each location, the images of the two human users are projected onto their respective robots in the remote locations. †¢ This gives each human the perception that he is working with another human instead of a robot. †¢ Right now, mutual telexistence is science fiction, but it won't be for long as scientists continue to push the boundaries of the technology. CHAPTER 6 : REAL WORLD APPLICATIONS: Chaitanya Institute of Engineering & Technology Page 11 OPTICAL CAMOUFLAGE †¢ Doctors performing surgery could use optical camouflage to see through their hands and instruments to the underlying tissue. Providing a view of the outside in windowless rooms is one of the more fanciful applications of the technology, but one that might improve the psychological well-being of people in such environments. †¢ Pilots landing a plane could use t his technology to make cockpit floors transparent. This would enable them to see the runway and the landing gear simply by glancing down. †¢ Drivers backing up cars could benefit one day from optical camouflage. A quick glance backward through a transparent rear hatch or tailgate would make it easy to know when to stop.CHAPTER 7 : OPTICAL CAMOUFLAGE SEEN IN: ? Ghost in the Shell. ? 2000 video game Deus Ex. Chaitanya Institute of Engineering & Technology Page 12 OPTICAL CAMOUFLAGE ? 2002 James Bond movie Die Another Day ? Metal Gear Solid and Halo video game series. ? The video game Phantom Crash. ? The Predator movie. CHAPTER 8 : ADVANTAGES & DISADVANTAGES ADVANTAGES: Chaitanya Institute of Engineering & Technology Page 13 OPTICAL CAMOUFLAGE ? Optical Camouflage can be used on surgical globes or equipments so they don’t block surgeon’s view during delicate operations. ?In aviation, cockpit floors could become ‘invisible' to assist pilots during landing. DISA DVANTAGES: ? The weak point of this technique is that the observer needs to look through a half-mirror. ? The current system needs a half-mirror and projectors, which were fixed on the ground. CHAPTER 9 : CONCLUSION: Now all of us have had a small tour of the interesting world of optical camouflage. A lot of interesting thing have been done and already we have seen that anyone can be almost invisible Chaitanya Institute of Engineering & Technology Page 14 OPTICAL CAMOUFLAGE ith this technology. Though we are still facing challenges with practicality, licensing and high costs the future promises us a lot more. To make an object literally vanish before a person's eyes, a cloak would have to simultaneously interact with all of the wavelengths, or colours, that make up light. That technology would require much more intricate and tiny meta-material structures, which scientists have yet to devise. Research work is going on and soon we will have even more astonishing results. Chaitanya Ins titute of Engineering & Technology Page 15
