Definition of Landscape

A landscape may be defined as scenery or something in the open that may be visually appealing to the human eye (Howard 30). In order to understand what landscape is, there is the aspect of experience and factors that contribute to why people like certain landscapes over others. According to Howard (30), certain landscapes may be appealing to the eye while others may be illicit the need to protect the landscapes. Historical landscapes relate to those areas that have either community parks, gardens, battlefields or rural communities that have a distinct physical appearance (National Park Service). Historical landscapes have ...

For this article, I have located an article from a known media news source on the subject of science. It deals with scientific research and findings, as well as additional critique by a second and different article. The theme for this study and analysis is that of the physiology of human color vision. The online article by OSA specifically describes the contents of a published scientific research experiment related to the topic. Having found the media article itself, I will then find the original media article which is being referenced by the OSA article, and in which that news ...

Abstract

Eye movement tracking and analysis has gained popularity as a critical tool for evaluating interfaces and visual display. Existing tools and methods that are used in analyzing scan paths and eye movements are to a greater extent limited in the nature of tasks that they support. In particular, the tools used have been found ineffective in tracking large amounts of data that has high variations. Eye movement analysis has been used in psychology, medical research, advertising, and cognitive science. Today, using CCTV cameras, human eye gaze, and eye movement and blinking is relatively recorded with ease and with high ...

Ultraviolet light (UV light) is a type of electromagnetic radiation that is located between visible light and X-rays in the electromagnetic spectrum. It is invisible to the human eye, and has a frequency greater than that of visible light but lesser than X-rays. It has a wavelength ranging from about 10 nm to 400 nm (ISO, 2007). UV light is a part of the radiation that comes from the sun. It can also be produced artificially by electric arcs, black lights, tanning lamps and mercury vapor lamps. The name Ultraviolet literally translates to “beyond violet”, as it has a ...

Crime scene investigation is an important area of the criminal justice field. The CSI groups are expected to find and collect evidence at crime scenes. They are to follow the guidelines of collecting the evidence and packaging it properly. The proper packaging is to ensure that the evidence stays fresh and does not get contaminated. They then ensure that the evidence is delivered at the proper analyzation and examination teams to further review the evidence. Once the evidence is reviewed and properly understood then the investigators continue with this information to obtain a warrant, capture a suspect, or use ...

“The land ethic,” which is found in the work of Aldo Leopold, A Sand County Almanac, is a theoretical philosophical framework. In it, Leopold tries to confront the weaknesses which he say encompass common environmental conservation. Leopold, a trained forester, and hunter, cherished and recognized the benefits of nature (Leopold, 2014). Having lived through the Dust Bowl and the Great Depression, he witnessed fertile top soil in southwestern Wisconsin blown away by the wind and eventually sip into the sea. These he observed were as a result of human activities and wondered how, despite the profit motives of man ...

Infrared Rays and Ultraviolet Rays

Infrared Rays Infrared (IR) rays are electromagnetic radiations with wavelengths 700nm – 1mm. Almost half of the sun’s energy is made up of infrared waves. They have frequencies of 4-7.5 *10^14 Hz, which is lower than that of visible red light. Hence, IR rays are not visible to the human eye. However, there are several animals which can see IR rays like the snake which uses infrared rays to hunt its prey. IR rays travel with the speed of light which is 300,000,000 meters/sec. IR waves are found in almost every object in the universe which ...

The purpose of this paper is to particularize the historical, science and technological impact of Li-Fi, to also include the vast reaching context of this incredible point in the wireless timeline. The paper seeks to establish the historic background of the Li-Fi technology as well as its technical working. The possibilities of Li-Fi extend to the application in military and undersurface communication operations. Traffic Management is another area where LED will be of great use. Li-Fi can be used in LED lights traffic managements. Other areas where Li-Fi will be ideal include disaster management, remote location positioning and dead ...

The earth as we see it is composed of different components that make up the earth we know day. These components vary from the physical elements that are seen by the human eye to strange and unexplained forces that are in the visible elements of the earth. This has triggered the scientists to devise ways in which they will understand fully what happens on earth and why it is in the shape it is today. The scientists through governments have sent into space different space satellites that are able to help them get the desired knowledge of the different ...

A Book Review

Color, it is defined as the most commonly appreciated aspects of life. The fact is, it is likely the first thing that captures the eyes of a young infant as it begins specifically aware of the environment surrounding him. Through the years of learning in schools, the factors of color is often explained within the top base only; deeply defining the constructs of what makes up color is often set aside, even considered less important for the students to be interested in. However, the fact is that color is a distinct element that makes up the real value of life. The ...

It is a shame that books like Jerry A. Conye’s best-selling book Why Evolution is True (2009) is necessary for the twenty-first century. After all, Charles Darwin wrote his groundbreaking work On the Origin of Species by Means of Natural Selection was published in 1859. Since its publication many other scientific discoveries have been made to support Darwin’s dangerous idea. Evolution should not be a controversial issue and sadly it remains so even in the most educated countries of the world. Part of the controversy could be because many people who oppose evolution have no idea what evolution is. ...

- Introduction Over the centuries, there has been the need to transmit secret information between a sender and a receiver. So many techniques have been developed and used in order to achieve this aim. One popular technique is cryptography; an art that encodes information as a cipher and can only be accessed by the sender or a receiver that knows the decryption code. The mere sight of coded information raises a lot of curiosity and suspicion. Anybody interested in such information may then commence efforts at deciphering the code. In order to eliminate this development, there was the need to transmit covert information ...

Me as Flashlight

Introduction: Inanimate representations can aptly elaborate the characteristics of an individual and the personality if one envisages the comparative similarities of the two. In my case, I feel from the innermost core of the heart that if I am to relate myself to any such inanimate object on the basis of similar traits, it has to be a flashlight. As I introspect, I find how my personality has common traits and how I could metaphorically be compared to a flashlight. An elucidation would make my argument reach everyone with more clarity and that is exactly what I would be doing. ...
