Abstract
The writer asks and answers questions concerning digital radio. Will this format be here to stay or will it just become a stepping stone technology? Will the world decide on a single transmitting format? And most importantly, will the general consumer accept this new technology? The beginnings of digital radio have already been seen. These stations, which are received via satellite, have been used by businesses to provide a variety of digital, commercial-free, music to be enjoyed by their customers.
From the Paper
"The future of digital radio in Canada relies mostly on the L-Band which Canada introduced to world in 1992. The L-Band is basically a carrier that uses both terrestrial and satellite signals for wireless transmissions. This makes for a carrier that far exceeds that of its predecessors, the FM and AM band, which the government plans to replace by 2010. After digital radio becomes the standard, the CRTC plans on using the AM/FM frequencies for other purposes of wireless transmission. AM radio covers the frequencies of 530KHz to 1630Khz for a bandwidth of 1.1MHz. The bandwidth needed, though, for each channel is 0.01MHz. FM covers the band of 88MHz to 108MHz for a total bandwidth of 20MHz, with 0.25MHz needed per channel. The L-Band on the other hand ranges between 500MHz to 1500MHz, although for digital radio only frequencies from 1452MHz to 1492MHz. are slated. This leaves digital radio with the bandwidth of 40MHz, where 1.5MHz of bandwidth is needed for the 48KHz, 16bit uncompressed audio."

"Storage virtualization is able to accomplish this by making physically separate and heterogeneous storage arrays seem to be a single logical pool of storage resources, controllable from a central console. The purpose of the program is for data to freely flow between the different tiers and types of storage, depending on business needs, without disturbing the operating environment. The author also asserts that "The single most important attribute of any storage virtualization solution is the ability to mask complexity and thereby make manageable that which is increasingly unmanageable.""

Abstract
This paper explains that, in spite of the usefulness and potential of the digital imaging process in hospital radiology departments, the cost of the equipment it requires has stopped digital imaging in hospital radiology departments from progressing and growing as fast as was hoped. The paper also explains that the slow progression towards digital imagery does not mean that the importance for the future that the technology holds should be discounted. The paper then discusses the two main types of digital imaging systems as they relate to hospital radiology departments and concludes with a discussion of image quality and its significance. A copy of the source documents used are also appended to the paper.

The Evolution of Digital Imaging
Computed Radiography (CR)
Digital Radiography (DR)
Image Quality
From the Paper
"Digital imaging in hospital radiology departments came about for several reasons. The most important of these, however, was the idea that the digital images could be viewed by any authorized person at any time, thus making it much easier and faster for those that needed to see them to have access to these images (Gillespie, 1999). These digital images eliminate the need for films and film libraries, thus freeing up space, as well. However, there are still problems with this issue that have stopped digital imaging in hospital radiology departments from progressing and growing as fast as was hoped. The major concern for these departments is the cost that is incurred when it comes to the digital imaging equipment, which is much more expensive than the older methods that were previously used to take x-rays and perform other functions (Gillespie, 1999)."

Abstract
This paper discusses digital television, comparing it to analog television. The paper presents an explanation and assessment of the current laws and mandates regarding digital television in America and in the United Kingdom. The paper explores the technology involved and provides examples of several cable companies that offer digital television.
From the Paper
"Though some providers of digital television like Sky claim that weather conditions do not affect the clarity of images on digital television, this fact has been demonstrated as not being true. Weather does affect digital images and there is a certain amount of corruption present. In fact, though the images are better than those of analogous television, the limitations of the compression technology that is used for digital television is apparent in the manner in which ?digital artifacts? or ?after images? as they are better known occur on the television when the picture changes much too fast, or even when other channels are fighting for the same bandwidth at the same time. Digital television must not be confused with ?high definition? television; in fact digital television occupies the same number of lines of 625, as the analogous television."

From the Paper
"This paper will discuss the concept of digital recording, with a focus on digital audio tape (DAT) recorders. The methods of digital recording sharply contrast those of analog recording which preceded them. Analog recording is based on the concept of capturing the shapes of sound waves as they vibrate in the air. In an analog recording, sound is "stored as a physical representation of the original soundform". An example of this can be seen in the squiggly lines which form the grooves on a phonograph record. With digital recording, on the other hand, computer technology is used to convert analog waveforms into numerical, or digital, data. In a compact disc (CD) player, this data is read by means of a laser; in a DAT player, it is read by means of a rotary tape head. Because digital recording uses numerical data instead of physical ...

Abstract
As the globe becomes more dependent on digital technology to exchange information over the Internet societies are becoming more concerned with issues of privacy. Individuals surfing the net, purchasing products over the Internet, and corresponding with others via the World Wide Web are required to provide personal information that has the potential of being used illegally in many ways. The United States has relied on the wording of the fourth amendment of the constitution in past years to address privacy issues in the country. Yet, as digital technology has evolved the focus on this amendment to resolve privacy concerns in relation to digital media is restricted by privacy in relation to search and seizure. This paper discusses the issues of privacy in relation to digital media, focusing on how these issues are handled in the United States and Canada.

Abstract
This paper defines digital radiography as a branch of radiography which converts X-ray images to electronic data which can then be viewed and read by radiologists on a monitor. The writer stresses the convenience of being able to store digital radiographic images on computer discs. This paper details the various uses and advantages of digital radiography including the fact that this particular method is quicker and far more accurate than the previous practice of producing x-ray images. This paper discusses the differences between computed radiography and digital direct radiography while also delving into the pros and cons of both radiographic methods.
From the Paper
"The 'Direct Digital Radiography' System provides options for the transition to digital technology. This system offers the highest quality images that are available in DR today. Developed only in recent years, the system can be used across a large number of potential applications. The advantages of the system are that it consists of two types of detectors, one direct and the other, indirect. In the setup for its imaging, indirect sensors convert x-rays into light, and then convert that into electronic signals. The images depend on both signal profiles as well as on image resolution. The system relies on a scintillation method, wherein x-ray energy may be converted into light, and this light can then be converted into electronic signals by thin-film diodes."

Abstract
This paper discusses the music recording industry and how it has been impacted by digital music distribution. The paper relates that the early success the music labels had against the initial music file downloading sites were short lived, and legitimate digital downloading sites have since prospered. The paper then argues that major recording labels are suffering from the decline in CD sales, not because of music pirating, but because they refuse to recognize that consumers demand digital music downloading for its convenience and portability. The paper further emphasizes that digital music distribution and retailing is the future of the music industry and every relevant party seems to recognize this, except the music industry itself.
Outline:
Overview
Restructuring of the music Industry
New distribution model & Itunes
Online distribution variations
Conclusion
From the Paper
"The music industry, in spite of its ineptitude and obstinacy over the past decade regarding digital music downloading, is finally realizing that whether it embraces downloading services such as iTunes and others, it must evolve with the digital age or face irrelevance. In order to compensate for the loss of revenues, the recording music industry has been examining their base revenues in order to determine if digital downloads can compensate completely for the decline in sales of CDs. Two of the major record labels, Sony and BMG, have even merged in order to expand their catalogues (Recording, 2007). There have been efforts made to encourage EMI to merge with one of the remaining three major record labels but thus far these remaining major record labels have resisted further consolidation. However, EMI undertook its own internal restructuring by merging its two main record labels in the US market during the first half of 2007 and Warner Music was sold during 2004 creating even more churn in the industry (Recording, 2007). Yet, perhaps the most visible change is the industry is the downsizing or disappearance of retail music stores, which has begun to accelerate."

Digital Black and White Photography, 2008.
An analysis of the history of digital photography and a comparison of its results with those of analog cameras, focusing on black and white developments.
1,353 words (approx. 5.4 pages), 7 sources, MLA, $ 45.95

Click here to show/hide summary
Abstract
This paper argues that digital cameras are better than analogue cameras. Specifically, the paper looks briefly at the history of digital photography, at its utility in matters such as record-keeping and crime-fighting and at some noteworthy instances of digital photography producing impressive and compelling works. Finally, the paper looks at all of the various reasons why it may be said that digital black and white photography is better than analog black and white photography.
From the Paper
"More than that, the technology that makes digital black and white photographs possible always runs the risk of becoming obsolete. For instance, the old Epson 2200, 7600, 9600 printers have been pushed aside by Epson Stylus Pro 4800, by the Epson Stylus Pro 7800, and by the Epson Stylus Pro 9800 (FLAAR Network, para.8); simply put, unlike the fairly low-maintenance prints rendered by analog cameras, the "splashy" digital B&W prints of today place photography enthusiasts in the uncomfortable position of seeking out new technological tools that have a (quite literally) a built-in obsolescence factor. Be that as it may, though, most photographers will gladly accept this trade-off if it means the chance to be more creative."

Abstract
There are many in today's society who do not have access to the internet and this fact automatically makes them 'digitally challenged'. This paper analyzes three articles which tackled the different dimensions or facets of the digital divide in the United States. Through the article analyses, the researcher posits that the problem of digital divide has multiple, rather than one, facet. This means that at present, the internet-oriented society confronts 'digital divides' of different kinds: Stratification in terms of access, use and even knowledge or education about the internet.
From the Paper
"At present, societies from all over the world are rapidly becoming Internet-oriented, where almost all daily activities are mediated by or use Internet and computer technologies. The vital role of the Internet is especially addressed in increasing one's level of knowledge and becoming an aid in achieving formal education. Moreover, because of the generally-beneficial effects of Internet technology to society, accessing and using it has become imperative for all members of these Internet-oriented societies.
However, a digital divide exists despite the proliferation of Internet technology and use. There are still stratified groups that do not have access to the computer and Internet. Moreover, apart from lack or absence of access, the lack of skills and knowledge to use the Internet is another problem that relevant institutions such as the government and schools have been trying to curb by offering free access and training programs to the public about Internet use."

Abstract
This paper discusses the issues and challenges involved in an enterprise-centric approach to the managing of digital content. The writer specifically focuses on the management of medical imagery, a field commonly referred to as digital asset management. Additionally, the writer discusses the need for standards that provide for the creation of digital medical imaging systems.
From the Paper
"At the center of integration efforts within the medical digital imaging system design efforts in the industry today is the creation of the virtually integrated electronic patient record (VIEPR), which is the basis of the future generation of wireless and web-based applications that are capable of "tracking" to patients as they progress through treatment programs. The VIEPR concept is aimed at taking digital medical imaging strategies and making them on an "always on" status that patients can present for analysis by medical professionals including radiologists and medical specialists. The future of thin-client based medical digital imaging delivery applications is based on this technology."

Abstract
In this article, the writer discusses how the act of business transactions have changed due to the progress in technology. The writer examines the effect of digital signatures on e-commerce, including the need for digital signatures. In this paper, the writer explores how digital signatures work. The paper also discusses the outlook for the future. Further, the writer looks at the importance of identity in cyberspace.
From the Paper
"For thousands of years transactions between individuals were conducted face-to-face. There was little doubt about who the buyer or seller was and when cash was involved it was not necessary to know for certain who was whom. Indeed even in today's high-technology world, cash transactions still carry the greatest amount of anonymity since the funds are guaranteed. As credit became more and more common, it became necessary to ensure that the persons involved with commercial transactions had the authority to perform those transactions."

Abstract
This paper explains how scanners can transfer text and pictures into digital form for manipulation and storage. The author points out that digital imagining allows storage in a smaller area. The paper relates that digital imagining manipulates information into a different format for use in desktop publishing of company documents and similar uses.
From the Paper
"Digital imaging has a wide variety of uses today, serving as a new means of photography, empowering office copiers, allowing for the transfer of images over long distances, and so on. Digital technology is computer technology translating information into a series of numbers, computer code that can be read and transformed back into the original form. Digital information can be text, sound, or pictures when translated, and in its digital form the information can be stored, retrieved, sent from one place to another, and altered, all with greater ease than changing the original material. Digital imaging in the workplace is found in office computers, copiers, fax machines, databases, and so on."

Digital Technology and Copyright, 2005.
This paper discusses digital technology and copyright infringement, focusing on the case of Napster.
2,700 words (approx. 10.8 pages), 6 sources, $ 106.95
»

Abstract
The paper explains that the case of Napster is typical of copyright infringement because it demonstrates just how inadequate legislation is as it relates to digital technology. The paper explains that in addition, Napster represents just one area where copyright can be violated. The paper shows how the Napster case reveals that in terms of digital technology, the fundamental issue concerns how to reconcile the traditional concept of contributory liability with the widespread use of digitized works made available by the Internet.
From the Paper
"With the advent of digital technology, research has found that as many as 90 percent of all Internet users and about 70 percent of users who share files freely admit that copyright is not an issue for them. These people regularly download many different kinds of files, ranging from movies to computer programs. The most likely individuals to download music and share files are students. Young adults behave in comparable ways since they also normally are not concerned about the copyright status of whatever files they download. Music is very easily downloaded, and it is far easier to download music than full-length feature movies."

4,739 words (approx. 19.0 pages), 66 sources, MLA, $ 121.95
»
Click here to show/hide summary
Abstract
This paper discusses the evolution of the digital art form that emerged as a combination of technological expertise and traditional artistic vision. The paper contends that the emerging digital technologies are creating new forms and genres of art, which are a result of the interaction between traditional views of art. The study of the collusion and interaction between technical knowledge and artistic imagination and innovation forms the central trajectory of this paper.
From the Paper
"An important aspect to consider in the evolution of digital art is the issue of legitimacy and acceptance. While the acceptance of digital art is far from ubiquitous there is now a strong basis for the recognition of digital art forms. (ibid) However, the hectic pace of technological development has meant that many artists feel inadequate in the face of technology that requires, in many cases, training and a mindset which is oriented towards a technological rather than a traditionally artistic point of view. Connected to this issue is the fact that art theory and aesthetics are struggling to assimilate these new technological methodologies."
