An Evolution of Computer Science Research∗
Apirak Hoonlor, Boleslaw K. Szymanski, Mohammed J. Zaki, and James Thompson

Over the past two decades, Computer Science (CS) has continued to grow as a research field. There are several studies that examine trends and emerging topics in
CS research or the impact of papers on the field. In contrast, in this article, we take a closer look at the entire CS research in the past two decades by analyzing the data on publications in the ACM Digital Library and IEEE Xplore, and the grants awarded by the National Science Foundation (NSF). We identify trends, bursty topics, and interesting inter-relationships between NSF awards and CS publications, finding, for example, that if an uncommonly high frequency of a specific topic is observed in publications, the funding for this topic is usually increased. We also analyze CS researchers and communities, finding that only a small fraction of authors attribute their work to the same research area for a long period of time, reflecting for instance the emphasis on novelty (use of new keywords) and typical academic research teams
(with core faculty and more rapid turnover of students and postdocs). Finally, our work highlights the dynamic research landscape in CS, with its focus constantly moving to new challenges arising from new technological developments. Computer science is atypical science in that its universe evolves quickly, with a speed that is unprecedented even for engineers. Naturally, researchers follow the evolution of their artifacts by adjusting their research interests. We want to capture this vibrant co-evolution in this paper.

Study Pn Evolution of Computer Software

...STUDY ON EVOLUTION OF COMPUTERS STUDY ON EVOLUTION OF SOFTWARE Introduction Computer software, or just software, is any set of machine-readable instructions that directs a computer's processor to perform specific operations. The term is used to contrast with computer hardware; the physical objects carry out the instructions. Hardware and software require each other and neither has any value without the other. The first theory about software was proposed by Alan Turing in his 1935 essay Computable numbers with an application to the Entscheidungsproblem (decision problem). Colloquially, the term is often used to mean application software. In computer science and software engineering, software is all information processed by computer system, programs and data. The academic fields studying software are computer science and software engineering. The types of software include web pages developed in languages and frameworks like PHP, Perl, JSP or ASP.NET and desktop applications like, Microsoft Word developed in languages like C, C++, Objective-C, Java, C#, or Smalltalk. Application software usually runs on underlying software operating systems such as Linux or Microsoft Windows. Software (or firmware) is also used in video games and for the configurable parts of the logic systems of automobiles, televisions, and other consumer electronics. Software evolution is the term used in software engineering (specifically......

...communities in diverse disciplines. Many of the grand challenge topics for engineering research  increasingly rely on the development and use of FOSS systems (e.g., the International Thermonuclear Energy Research (ITER) project for fusion research), and in some topics, the development and experimentation with FOSS-based systems are likely to be central to future research activities (e.g., advanced health informatics, secure cyberspace, enhanced virtual reality, and advanced personalized learning systems). However, FOSS remains a computing technology at its core, while FOSS development remains a web of complex socio-technical processes. But these processes are not well understood nor readily predictable, as informal practices are widespread and continually adapting. As such, FOSS is amenable to technological advances, socio-technical innovations, and systematic empirical studies that can emerge from research in the Computer Science community and beyond. We seek to articulate both multi-disciplinary and inter-disciplinary perspectives on how and why FOSS has become such a source of technology-centered global transformation, and what the future may hold. We need to identify key research problems and experimental studies going forward, along with the requisite research infrastructure and shared data repositories needed to support this research. We also need to identify future roles that Computer Science can play in fostering, sustaining, and expanding the ongoing development of......

An Automated Hostel and Room Allocation System.

...ABSTRACT AN AUTOMATED HOSTELS AND ROOMS ALLOCATION SYSTEM (CASE STUDY OF YABA COLLEGE OF TECHNOLOGY) This Project work intends to address some of the problems encountered in the allocation of hostels and rooms to students manually in Yaba College of Technology. The growing number of students in higher institutions posed a lot of accommodation problems on the part of students and School Management. Some of the problem caused includes, few hostels that exist in the College are not properly managed, Statistic of rooms required to match the growing numbers of students are farfetched, Student pays fee for hostel and may end up not getting rooms because of lack of bed space, Hostel administrators cannot give accurate information of the occupancy of a particular room. In respect to all these existing problems, a system will be designed to manage a database for allocating hostel and room to student. The system designed will keep track of all the available rooms, their occupants and funds generated from hostel fees. The New system will be implemented using Visual Basic 6.0 and Ms Access Database. CHAPTER ONE INTRODUCTION 1.1 BACKGROUND OF THE STUDY In 1912, in Altena Castle in Germany, Richard Schirrmann created the first permanent Jugendherberge or "Youth Hostel". These first Youth Hostels were an exponent of the ideology of the German Youth Movement to let poor city youngsters breathe fresh air outdoors. The youths were supposed to manage the......

Role of Information Technology

...The History of Information Technology March 2010 Draft version to appear in the Annual Review of Information Science and Technology, Vol. 45, 2011 Thomas Haigh University of Wisconsin, Milwaukee Thomas Haigh The History of Information Technology – ARIST Draft 2 In many scholarly fields the new entrant must work carefully to discover a gap in the existing literature. When writing a doctoral dissertation on the novels of Nabokov or the plays of Sophocles, clearing intellectual space for new construction can be as difficult as finding space to erect a new building in central London. A search ensues for an untapped archive, an unrecognized nuance, or a theoretical framework able to demolish a sufficiently large body of existing work. The history of information technology is not such a field. From the viewpoint of historians it is more like Chicago in the mid-nineteenth century (Cronon, 1991). Building space is plentiful. Natural resources are plentiful. Capital, infrastructure, and manpower are not. Boosters argue for its “natural advantages” and promise that one day a mighty settlement will rise there. Speculative development is proceeding rapidly and unevenly. But right now the settlers seem a little eccentric and the humble structures they have erected lack the scale and elegance of those in better developed regions. Development is uneven and streets fail to connect. The native inhabitants have their ideas about how things should be done, which......

Food Safety Audit

...Why Should People Hate Science? Science has conquered so many diseases and is promising to cure genetic diseases and even grow us new organs. It has given us mobile phones, tablets and computers that have reduced the global village to a global mall; and yet, there are people who still refuse to accept the power of science as the major agent of change in our society. Some people find it easier to believe that special people can cure serious diseases by simply placing their hands on the diseased, while others cannot accept the fact that human beings evolved from lower animals by a process of Natural Selection over billions of years. Locally, it is a no-brainer that the lack of science teaching at a primary level has had a negative lasting effect on people, and this can be seen in newspaper, radio and TV station editors, opinionists, politicians and talk-show hosts, all of which wield the power of mass media and can influence public opinion and what people think. Unfortunately, many of them are educating the masses in the concept of GIGO - Garbage In Garbage Out. GIGO is an interesting concept that refers to the fact that people are continously bombarded by pseudo-scientific and mistaken ideas, and eventually start believing their veracity and transmit them to others. These people are not necessarily uneducated individuals, but usually pick the information online and reinforce false opinions by choosing websites that agree with their views. For example, they......

Transformation of Media Forms

...Forms The theory of evolution from paper to the internet  The theory of evolution must ‘evolve’ with the transforming media forms around it to maintain its scientific and social relevance. In other words, it must shift from the conventional media forms such as journals, books and publications and move towards the ways of the internet. Even collective groups of scientists and evolutionists can be shifted from physical to online gatherings via the ways of the internet and its related technologies. The majority of internet users throughout the world see the net as simply an enormous link-up of the world’s computers, after all, this is the ‘universal answer’ people tend to give when asked “what is the internet?”. Although this common answer is a pretty accurate image, it would be more correct to describe the internet as a “global network of hardware and software which stores and transports information from a content provider to an end user” . This infrastructure allows any person who wishes to say anything, access to say it to the world. Controversial topics are abundant on the World Wide Web, and this media form enables these topics to be discussed, investigated, or challenged. Evolution is defined as being: “A gradual process in which something changes into a different and usually more complex or better form”.  Arguments for evolution include The Fossil Record, Darwin’s theory of Natural Selection, and Biological Evidence. Arguments against evolution include The Second......

System Theory

...elements and relations determines an emergent* organization, or system*. That organization is abstract, independent of the concrete substance of the elements, which may be atoms, molecules, cells, transistors, or people. This entails that the same principles of organization can be found in different domains: physics, chemistry, biology, psychology, sociology, technology... One of the aims of systems theory is to unify different scientific disciplines by uncovering these general principles (see unity of science*). Systems theory studies characteristics common to many or all complex systems. These include: system-environment boundary*, input*, output*, process*, state*, evolution*, hierarchy*, goal-directedness*, information*. Most of these concepts are shared with the closely related domain of cybernetics*, which focuses on communication* and control*. These concepts have been made more precise in elaborate mathematical...

Evolution and Media Naturalness: a Look at E-Communication Through a Darwinian Theoretical Lens

...EVOLUTION AND MEDIA NATURALNESS: A LOOK AT E-COMMUNICATION THROUGH A DARWINIAN THEORETICAL LENS Ned Kock Lehigh University/Temple University Bethlehem, PA/Philadelphia, PA USA Abstract Modern theories of human evolution converge on the belief that our brain has been designed to cope with problems that occurred intermittently in our evolutionary past. Evidence suggests that, during over 99 percent of the evolutionary process leading to the emergence of our species, our ancestors communicated in a synchronous and colocated manner, and employing facial expressions, body language, and oral speech (what we refer to here, generally, as “face-to-face” communication). Thus, it is plausible to assume that many of the evolutionary adaptations our brain has undergone in connection with communication have been directed at improving the efficiency and effectiveness of face-to-face communication, which begs the question: What happens when we selectively suppress face-to-face communication elements (e.g., colocation, the ability to employ/observe facial expressions) through e-communication technologies? This paper tries to provide an answer to this question by developing a hypothesis, called the media naturalness hypothesis, which builds on modern human evolution theory. The media naturalness hypothesis argues that, other things being equal, a decrease in the degree of naturalness of a communication medium (or its degree of similarity to the......

In this, computers are used in gathering, storing, analysis and the merging of biological data. Bioinformatics is not a research area by itself but lies between biological sciences and computational sciences. The main goal of bioinformatics is to review the value of biological information that is hidden in the large amount of data come up a clear picture of the basic biology of organisms. There are several fields that have been revolutionized by the technology used in bioinformatics (Ouzounis & Christos, 2012). These fields include human health, the environment, agriculture, energy and biotechnology. This science of bioinformatics is also called computational biology and has found a lot of use in increasing the quality of life. Bioinformatics developed due to the great need to internalize the DNA which is the code of life. Growth in the field of bioinformatics has been facilitated by development of many DNA sequencing projects. The basic biology of life is controlled by the basic molecule of life called DNA. The DNA acts as the blue print for genes which code for proteins. The proteins coded......
