Visual cryptography allows to encrypt information that is available in the form of white and black pixels. The decryption can be done only by using the optical perception, in particular the help of computers required.

To write a successful research paper on the topic you should know that visual cryptography visual cryptography was first introduced Moni Naor and Adi Shamir in 1994. It was used to encrypt the image or the text presented in the form of images. The basic idea of the visual cryptography model was to break the original image into a plurality of encrypted images (or shadow images), each of which would give no information about the original image except maybe its size (image – a la “white noise”). When superimposing the encrypted images, the original image can be obtained. Thus, the decoding does not require special knowledge, HPC and even computer (if shadow images are printed on transparencies). Continue reading “Visual Cryptography Research Paper”

Youth homelessness in the United States reached a record level by the end of the 2011-2012 school year. At this time there were about 1.2 million of the homeless young people.

In the 2011-2012 academic year in the United States, there were about 1.2 million homeless students. As a specialized research center funded by the U.S. Department of Education reported, it was the highest level on record. It is 10% higher than the previous year, and 72% higher than in the pre-crisis years.

To prepare a research paper on youth homelessness you should know that the term refers to the children and adolescents from the families who have lost their own homes. Many of them continue to attend classes in public schools, even those living in shelters, but do not wish at the same time to get registered. In addition, homeless parents fear that their children could be simply taken away from them. Therefore, as the expert from the National Association for the Education for Homeless Children and Youth Barbara Duffield explained, the real picture is probably worse than the official statistics. According to her, there is a problem even in high school. This year, more than 58,000 students of universities and colleges in the United States indicated in applications for grants to study from the federal government, they do not have housing. A year ago, they were almost 4,500 less. However, these statistics are also known to be incomplete, since many families are unaware or unwilling to admit their affiliation to the needy.

Carbon dioxide (Latin name: Dioxidum Carboni) is a very common gas, which is odorless and colorless in normal temperatures. Currently (July 2013), it represents the approximately 397 ppm of the atmospheric volume. Concentration in the atmosphere increases with a rising rate and the growth is currently at just over two ppm per year on average. Carbon dioxide has a significant biological importance, playing a vital role in the earth’s climate and has many industrial applications.

Those who write research paper on the topic should know the main toxicological properties of carbon dioxide:

• Odor: No odor warning. In high concentrations, however, has faintly pungent odor.
• Features: The gas is heavier than air. Risk of accumulation in confined spaces, particularly at ground level. Highest CO2 concentration is normally found in the room’s lowest point.
• Suffocating by inhalation as it displaces oxygen in the air.
• Even low concentrations cause rapid circulatory insufficiency.

Theory of Constraints is a repository of knowledge, methods, and tools for interdisciplinary management of organizations. The lead author is Eliyahu M. Goldratt, with other contributors.

The theory of constraints is a fundamental principle that the flow generated by an organization is limited by at least one process, that is to say, a neck or bottleneck. Production value can be increased by increasing the production capacity at the bottleneck.

Those who are writing their research paper on theory of constraints have to know that there are five key stages of implementation of the theory of constraints:

1. Identify the constraint (bottleneck).
2. Exploit the constraint (increase its use and efficiency).
3. Make all processes in the process forced.
4. Raise the performance of the constraint (if necessary).
5. Repeat step 1 if the constraint has changed.

Carbon emissions mean the total amount of CO? released in the atmosphere, due to direct and indirect human activity.

Since there is still no internationally accepted definition, it refers to greenhouse gases even involving additional factors.

Carbon emissions (measured in CO?) and greenhouse gas emissions (measured in CO? equivalents) are often measured in tonnes per year or in vehicles in grams per kilometer.

Students who write their research papers on the topic must know that carbon emissions have increased in recent years, especially since it could became a useful tool to determine the climate impact of products, services, and other events in the life of every person. Only with this information we can effectively minimize the climate impact by providing symmetric country measures – for example, to reach the limiting of the global warming to 2° C.

The cause of many diseases is a reaction to modern living conditions and lifestyle. Stressful situations can have a catalytic effect, but can also lead to disease. Stress, especially if it is frequent and lengthy, have a negative effect on the psychological state as well as physical health.
When a conflict situation requires quick reaction and immediate response, the body triggers the mechanisms of adaptation.

Those college students who are about to prepare their first research paper on stress and health have to know that stress interferes with the person’s behavior, leading to such common disorders as depression, anxiety, emotional instability, neurosis, mood decline, or, conversely, anger, excitement, fatigue, insomnia, impaired memory, etc.).

Stress can manifest itself, for example, through high blood pressure, inability to fall asleep at night or on weekends. People exposed to stress, often feel tired. Various trivia or other people remarks may seem so annoying to them that it can bring people out of themselves for the day. Stress weakens the body’s resistance forces, causes changes in the autonomic nervous system, hormonal glands, and metabolism. Continue reading “Research Paper on Stress and Health”

The capital punishment in the United States of America has been debated. More than 15 000 people are believed to have been executed in the U.S. since 1608, with more than 1100 since the death penalty was reinstated in 1976 after a nine-year hiatus. In 1972, after a historic five-year moratorium, the country’s highest court said the death penalty to be incompatible with the U.S. Constitution, which practically meant that the death penalty could not be imposed as criminal sanctions. A major criticism was that there was arbitrariness in how and when the death penalty was sentenced.

But in 1976, several states have tightened up the rules for how a trial that examined a prosecution that could lead to the death penalty would be carried out. The Supreme Court was pleased with this, and since then, the death penalty has been re-established as punishment for crimes in the United States. Since 1977 (when the last execution was effected in France) the U.S. is the only state in the West to keep the death penalty in practice, although a few other democracies (Japan, India, Taiwan, Botswana and Indonesia) regularly effects executions.
