As a student of computer science, there's a significant chance you will end up working in software development after graduation. Despite whether your career path takes you into industry or academia, you're likely to have some kind of interaction with software development companies or organizations, if only in trying to get the most out of a project or collaboration.

While touchscreens allow extensive programmability and have become ubiquitous in today's gadgetry, such configurations lack the tactile sensations and feedback that physical buttons provide. As a result, these devices require more attention to use than their button-enabled counterparts. Still, the displays provide the ultimate interface flexibility and thus afford a much larger design space to application developers.

This article describes a technique to visualize query results, representing purchase orders placed on Amazon.com, along a traditional 2-D scatter plot and a space-filling spiral. We integrate 3-D objects that vary their spatial placement, color, and texture properties into a visualization algorithm. This algorithm represents important aspects of a purchase order based on experimental results from human vision, computer graphics, and psychology. The resulting visual abstractions are used by viewers to rapidly and effectively explore and analyze the underlying purchase orders data.

Computational semantics has become an interesting and important branch of computational linguistics. Born from the fusion of formal semantics and computer science, it is concerned with the automated processing of meaning associated with natural language expressions [2]. Systems of semantic representation, hereafter referred to as semantic formalisms, exist to describe meaning underlying natural language expressions. To date, several formalisms have been defined by researchers from a number of diverse disciplines including philosophy, logic, psychology and linguistics. These formalisms have a number of different applications in the realm of computer science. For example, in machine translation a sentence could be parsed and translated into a series of semantic expressions, which could then be used to generate an utterance with the same meaning in a different language [14]. This paper presents two existing formalisms and examines their user-friendliness. Additionally, a new form of semantic representation is proposed with wide coverage and user-friendliness suitable for a computational linguist.

Electronic commerce faces the problem of signing electronic contracts. Three approaches for handling electronic contracts include 1) no trusted third party protocols, 2) strongly-trusted third party protocols and 3) weakly-trusted third party protocols. A secondary problem facing electronic commerce is self-enforcing contract design.

Doctoral students often find it hard to understand at what level of productivity they should be. Through an analysis of resums of doctoral students in the Management Information Systems (MIS) field, a better understanding of what is expected of current students as compared to former students is achieved. Both conference presentations and publications in journals are examined. Finally, there is an examination of whether the quantity of publications can be related to the ranking of the school that a student attends.

Advances in computing have awakened a century old teaching philosophy: learner-centered education. This philosophy is founded on the premise that people learn best when engrossed in the topic, participating in activities that motivate learning and help them to synthesize their own understanding. We consider how the object-oriented design (OOD) learning tools developed by Rosson and Carroll [5] facilitate active learning of this sort. We observed sixteen students as they worked through a set of user interaction scenarios about a blackjack game. We discuss how the features of these learning tools influenced the students' efforts to learn the basic constructs of OOD.

Robotic soccer is a challenging research domain involving multiple agents that need to collaborate in an adversarial environment to achieve specific objectives. This article describes CMUnited, the team of small robotic agents that we developed to enter the RoboCup-97 competition. We designed and built the robotic agents, devised the appropriate vision algorithm, and developed and implemented algorithms for strategic collaboration between the robots in an uncertain and dynamic environment. The robots can organize themselves in formations, hold specific roles, and pursue their goals. In game situations, they have demonstrated their collaborative behaviors on multiple occasions. The robots can also switch roles to maximize the overall performance of the team. We present an overview of the vision processing algorithm which successfully tracks multiple moving objects and predicts trajectories. The paper then focuses on the agents' behaviors ranging from low-level individual behaviors to coordinated, strategic team behaviors. CMUnited won the RoboCup-97 small-robot competition at IJCAI-97 in Nagoya, Japan.

The increasing demands of 3D game realism - in terms of both scene complexity and speed of animation - are placing excessive strain on the current low-level, computationally expensive graphics drawing operations. Despite these routines being highly optimized, specialized, and often being implemented in assembly language or even in hardware, the ever-increasing number of drawing requests for a single frame of animation causes even these systems to become overloaded, degrading the overall performance. To offset these demands and dramatically reduce the load on the graphics subsystem, we present a system that quickly and efficiently finds a large portion of the game world that is not visible to the viewer for each frame of animation, and simply prevents it from being sent to the graphics system. We build this searching mechanism for unseen parts from common and easily implemented graphics algorithms.

Contemporary computers predominantly employ graphical user interfaces (GUIS) and colour is a major componenet of the GUI. Every man-machine interface is composed of two major parts:the man and the machine [4]. Color interfaces are no different in that they are also based on two parts, the Human visual system (HVS) and a color display system. A theoretical examination of these two components establishes a foundation for developing practical guidelines for color interfaces. This paper will briefly examine theoretical aspects of both components and established techniques and tools for the effective use of color for software interface design.

Virtual Reality hype is becoming a large part of everyday life. This paper explores the components of actual virtual reality systems, critiquing each in terms of human factors. The hardware and software of visual, aural, and haptic input and feedback are considered. Technical and human factor difficulties are discussed and some potential solutions are offered.

The explosive growth of networked and internetworked computer systems during the past decade has brought about a need for increased protection mechanisms. This paper discusses three authentication protocols that incorporate the use of methods that present effective user authentication. The first two protocols have been previously discussed in the literature; the third protocol draws from the first two and others to produce an authentication scheme that provides both mutual authentication and secure key distribution which is easy to use, is compatible with present operating systems, is transparent across systems, and provides password file protection.

This paper attempts to raise some issues that are important for graduate students to be successful and to get as much out of the process as possible, and for advisors who wish to help their students be successful. The intent is not to provide prescriptive advice -- no formulas for finishing a thesis or twelve-step programs for becoming a better advisor are given -- but to raise awareness on both sides of the advisor-student relationship as to what the expectations are and should be for this relationship, what a graduate student should expect to accomplish, common problems, and where to go if the advisor is not forthcoming.
