Free Virtual Reality Research Paper:
Virtual reality is a term referring to visual and sound effects, generated by a computer, which allows the viewer to immerse into the imaginary environment behind the screen. A user is surrounded by computer generated picture and sound that give him a sense of reality. The user interacts with the virtual world through a variety of sensors, such as, for example, helmet and gloves, which make possible to control virtual reality through the user’s movements recognition. Future researches in the field of virtual reality are aimed at increasing the impression of the reality observed.
Virtual Reality is a new technology of contactless information interaction that realizes an illusion of presence in a real-time virtual environment presented on the screen through the integrated multimedia operating system. More abstractly, it is an imaginary world, which is perceived by the user through the software-hardware complex as real. Continue reading
Visual light communication is a type of optical data transmission between two points (source and receiver), which are on a line of direct visibility.
Optical data transmission is usually realized by means of optical fibers, since they allow to transfer information over considerable distances without major power losses, matching issues, and atmospheric noise (disturbance). There is a possibility of data transmission over the spaces of free visibility without using any waveguide structures. This type of optical communication is known since Alexander Bell patented a «photo phone» in 1870.
Today, it is used more and more often both on Earth and in space. Typically, this type of communication requires direct visibility between the transmitter and the receiver, and special atmospheric optical systems, such as telescopes. As the light source, a laser is often used (sometimes with the amplifier). However, there still are problems to be solved. Continue reading
Free Vedic Maths Research Paper:
It is believed that the foundations of modern mathematics – its geometric part – were laid by Euclid, and the foundations of differential calculus – the basis of modern mathematical analysis – were presented in the writings of Newton and Leibniz. There is, however, a number of works that are unknown to wide range of readers, which address a mathematical knowledge contained in the Vedas – the ancient monument of human culture, which is, at least for a few thousand years, older than all famous ancient Greek writings.
The Vedas (from Sanskrit – source of knowledge), according to Indian beliefs, contain all the knowledge, both scientific and ethical, initially given to humankind. The Vedas, originally written in Sanskrit in the form of short sayings (sutras), do not contain theorems and mathematical calculations. Continue reading
Quality education is an effective way to transfer the most valuable and relevant experience of the previous generations, so that students were able to master it with maximum efficiency.
Modernization of modern education is not possible without clear answers to key questions of its construction: for what (goals and values), what (content) and how (technology) to teach students.
Every branch of science has its own specific strategies of learning and descriptions of the world, due to which people are able to predict many phenomena, processes and events taking place in objective reality. These strategies are expressed in a specific language of each science, in the specific features of its construction, in the complex of basic concepts, experience, organization of research activities and scientific traditions.

Vikings Research Paper:
The Vikings were mostly medieval Scandinavian seamen in the VIII-XI centuries, who made sea trips from the Caspian Sea to North Africa and from Vinland to Bjarmland. In the bulk, these were free peasants, who resided in what is today Scandinavia and were pushed outside their home countries by overpopulation and the thirst for easy money. By religion, the vast majority were nations.
The Swedish Vikings and the Vikings lived on the Baltic coast, usually traveled to the east and were presented in ancient and Byzantine sources under the name of Vikings.
Norwegian and Danish Vikings were moving mostly to the west and were known by the Latin name Normanni. The Scandinavian sagas can give an inner look at the Vikings existence, but this source cannot be considered reliable due to its often later date of compilation and writing. Continue reading
Animal Rights and Medical Experiments Essay:
The use of animals for scientific purposes in medical experiments to receive a better understanding of a particular disease, to develop new drugs or to check the security of a drug raises many conflicting reactions. Some people strongly believe that there are no moral problems in this issue, while the others rush in the opposite direction with extreme opinions ready to justify animal welfare as a whole with violence. In fact, a recent survey of public opinion found that, for instance, citizens of the United Kingdom either refer to the experiments on animals with disapproval and cautiously, or believe that they should be banned completely. Still, even though there are a lot of people who can provide stable and considerable arguments to both sides of the argument around the world it is clear that abandoning animal experiments is a dubious decision since in the 21st century it is the only way to prevent human experiments.
First of all, experiments on animals present a huge industry. Each year only British scientists use almost 3 million of animals for research purposes. Most often these are rats and mouse, but 1% of them includes rabbits, and 0.1% – monkeys. Mostly, these animals are used for development and testing of medicines to treat human disease, although every year about 17,000 animals are used to verify the safety of food supplements and household equipment chemistry. At the same time, there is a fact that now a number of animals exposed to similar experiments is significantly reduced (Rowan 79). However, in addition to all this, undoubtedly, there is a negative side of this issue since, for instance, the Ministry of Defense can test different types of weapons on animals almost without publishing such data. Still, generally, traditional tests on animals gradually taper to nothing, and there are new areas of experimental study (Mukerjee 94). For example, now more animals are used for experiments on gene engineering (Anderegg et al. 6). In some cases, human genes are implanted in an animal. Such transgenic animals can develop diseases which are very similar to human diseases. Studying impact of the disease on the body of transgenic animals, scientists can find out the causes of human diseases. Consequently, this gives them much more opportunities to develop new types of treatment of several human diseases (Rowan 79). Continue reading
Free research paper on Tidal Energy:
Tidal energy is a renewable source of energy, which is produced by the surge of ocean waters during the rise and fall of tides.
For centuries, people have speculated on the cause of tides. Today we know for sure that a powerful natural phenomenon is a rhythmic movement of marine water caused by the force of attraction of the Moon and the Sun. Since the Sun is 400 times further from Earth, much smaller mass of the Moon affects the Earth pods twice as much as the mass of the Sun. Therefore, most tides are lunar.
In the vast sea rises and falls alternate each other theoretically every 6 hours 12 minutes 30 seconds. When the Moon, the Sun, and the Earth are on a line (the so-called syzygy), the Sun increases the moon attraction and then comes the strong tide (spring tide, or big water). When the sun is at right angle to the Earth-Moon line (Quadrature), there is a weak tide (neap or low water). Strong and weak tides alternate each seven days. Continue reading
The power imbalance between the North and South has resulted to a number of conflicts.
The military power of the North has dominated the South, making the Southerners have no say in the global matters. This situation has seen the Southern states depend on the North for their security. Power imbalance in terms of the economy is seen in the global markets and the ownership and governing of international institutions. These institutions have become center sites for the interaction between the North and South states when it comes to technology, finance, and trade. However, this interaction is not free. It is done under conditions with the North benefiting more than the Southern states. There are limits and consequences of change The Northern states have come up with number trade agreements that have seen them benefit more from the international trade. They have made multilateral negotiation with the aim of dominating international trade through market access and regulations. Continue reading
Recidivism is a model of repeating antisocial or criminal behavior.
Most first time offenders took the path of crime as a minor or in the first years of adulthood. There is the following relationship between the age of criminal at the time of the first violation and subsequent recidivism. The earlier the first crime was committed, the more intense and virulent is the recidivism. 70% of offenders committed their first crime at the age of 18. The older the person, who commits the offense for the first time, the less the probability of recidivism. There are almost no recidivists among individuals, who committed their first violation in old age and the crime they committed are way less virulent. Continue reading
The right of any person to education is one of basic human rights.
The right to education is one of the most significant constitutional social rights, which creates prerequisites for the development of the personality, and whole society. Enshrined in virtually every major law, since the Mexican Constitution in 1917, the content of this right has a tendency to expand. Currently in democracies right to education in the broad sense includes the right to: a free primary or secondary education in state and municipal schools and other educational institutions, the parents priority in choosing the form of the education (religious and secular) for their child, freedom of teaching, and organization of private schools. Many constitutions reinforce right to education by the parents responsibility (or persons in loco parentis) to ensure that their children receive primary (or general basic education). Continue reading
