Intelligent Software Systems In Historical Context, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

The purpose of this chapter is to trace the evolution of intelligent software from data-centric applications that essentially encapsulate their data environment to ontology-based applications with automated reasoning capabilities. It is argued that a distinction may be drawn between human intelligence and component capabilities within a more general definition of intelligence, and that such component capabilities can be embedded in computer software. The primary vehicle in the quest for intelligent software has been the gradual recognition of the central role played by data and information, rather than the logic and functionality of the application. The three milestones in this evolution …

Y: New Component-Based Software Life Cycle Model, Luiz Fernando Capretz

Electrical and Computer Engineering Publications

With the need to produce ever larger and more complex software systems, the use of reusable components has become increasingly imperative. Of the many existing and proposed techniques for software development, it seems clear that component-based software development will be at the forefront of new approaches to the production of software systems and holds the promise of substantially enhancing the software production and maintenance process. Attempts to rationalize component-based development have to recognize that the construction of a software system is a complex multifaceted activity that involves domain engineering, frame working, assembling, archiving and design of software components. These activities, …

Interoperability And The Need For Intelligent Software, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

In my introduction to this year’s conference I will address six questions that I believe come to the core of our conference theme of interoperability. Do we human beings resist change? Is it in fact a human problem and not a technical problem that we are dealing with? Can non-human intelligence exist? Do we even have a need for intelligent software? How did software, particularly intelligent software (i.e., if we accept that there is such a thing) evolve over the past several decades, and what is all this talk about a Semantic Web environment? And, finally, what does the …

Are Use Case And Class Diagrams Complementary In Requirements Analysis? An Experimental Study On Use Case And Class Diagrams In Uml, Keng Siau, Lihyunn Lee

Research Collection School Of Computing and Information Systems

Despite the status of united modeling language (UML) as the de facto standard for object oriented modeling, it has received controversial reviews. The most controversial diagram in UML is the use case diagram. Some practitioners claim that use case diagrams are not valuable in requirements analysis and some have even argued that use case diagrams should not be part of UML. This research examined the values of use case diagram in interpreting requirements when use case diagrams are used in conjunction with class diagrams. In other words, the study investigated the possible synergetic values and relationships between the use case …

Design And Analysis Of A Cooperative Medium Access Scheme For Wireless Mesh Networks, Arup Acharya, Archan Misra, Sorav Bansal

Research Collection School Of Computing and Information Systems

This paper presents the detailed design and performance analysis of MACA-P, a RTS/CTS based MAC protocol, that enables simultaneous transmissions in wireless mesh networks. The IEEE 802.11 DCF MAC prohibits any parallel transmission in the neighborhood of either a sender or a receiver (of an ongoing transmission). MACA-P is a set of enhancements to the 802.11 MAC that allows parallel transmissions in situations when two neighboring nodes are either both receivers or transmitters, but a receiver and a transmitter are not neighbors. The performance of MACA-P in terms of system throughput is obtained through a simulation of the protocol using …

Informal Animation Sketching: Requirements And Design, Richard C. Davis, James A. Landay

Research Collection School Of Computing and Information Systems

We present an interface design for creating informal animations from sketches. Current tools for creating animation are extremely complex. This makes it difficult for designers to prototype animations and nearly impossible for novices to create them at all. Simple animation systems exist but severely restrict the types of motion that can be represented. To guide our design of an animation sketching interface, we conducted field studies into the needs of professional and novice animators. These studies show the wide variety of motions that users desire in informal animations and indicate how to prioritize these types of otion. The interface described …

Development Of A Systems Engineering Model Of The Chemical Separations Process: Final Report, Yitung Chen, Sean Hsieh

Separations Campaign (TRP)

The whole chemical separation process is complex to the point that definitely requires certain level of systematic coordination. To perform smoothly and meet the target extraction rates among those processes, this research proposed a general-purpose systems engineering model.

A general purposed systems engineering model, Transmutation Research Program System Engineering Model Project (TRPSEMPro), was developed based on the above design concept. The system model includes four main parts: System Manager, Model Integration, Study Plan, and Solution Viewer. TRPSEMPro can apply not only to chemical separation process, but also a general system model.

Indeed, some systems based on …

A Visual Language For Animating Sketches, Richard C. Davis, James A. Landay

Research Collection School Of Computing and Information Systems

We present our research into visual languages for animating sketches. Animation is a rich mode of communication that is currently accessible to few. Simple animation systems exist, but severely restrict the types of motion that can be represented. Our field studies are demonstrating that would-be animators need to coordinate many objects moving in a variety of ways. The visual language described here allows a variety of motions to be defined with hand gestures, and gives visual feedback for coordination of events. This may open up computerized communication to users who think in dynamic visual images.

Exploiting Information Theory For Adaptive Mobility And Resource Management In Future Cellular Networks, Abhishek Roy, Sajal K. Das, Archan Misra

Research Collection School Of Computing and Information Systems

We utilize tools from information theory to develop adaptive algorithms for two key problems in cellular networks: location tracking and resource management. The use of information theory is motivated by the fundamental observation that overheads in many aspects of mobile computing can be traced to the randomness or uncertainty in an individual user's movement behavior. We present a model-independent information-theoretic approach for estimating and managing this uncertainty, and relate it to the entropy or information content of the user's movement process. Information-theoretic mobility management algorithms are very simple, yet reduce overhead by ∼80 percent in simulated scenarios by optimally adapting …

Pre-Conference Proceedings Of The Focus Symposium On Intelligent Software Systems For The New Infostructure: Baden-Baden, Germany, Collaborative Agent Design Research Center

Collaborative Agent Design (CAD) Research Center

Over the past several years the papers in this annual series of symposia have increasingly centered on the realization of a human-computer collaboration environment in which computer-based software agents with reasoning capabilities provide meaningful support to human decision makers. It is therefore quite appropriate that the first paper in the 2004 Proceedings should address the historical evolutionary path of ‘intelligent’ software leading to the goal of a semantic Web environment. The realization of this goal is now in sight, driven by public security threats that are increasingly relying on technology for effective countermeasures.

Knowledge Management Using Semantic Web Languages And Technologies, Steven J. Gollery, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

Each organization of more than a few persons generates a number of documents containing information about the activities of the organization. The sum of these documents provides a kind of organizational memory that can be used both in evaluations of past performance and as the basis of future planning based on previous experience.

Unfortunately, the nature of these documents mitigates against the reuse of information for purposes other than those for which each document was originally intended. To locate all the information about some aspect of the organization, it frequently becomes necessary for human beings to search a mass of …

Development Of Web Tools For Nlx Simulation Software, Daniel Chai Siriphongs

Loma Linda University Electronic Theses, Dissertations & Projects

Valuable mathematical equations have developed within biology and other sciences (physics, chemistry, etc.) that model various processes, but the complexity of the equations are not easily understood by students, scientists, and those with limited knowledge of the subject area. Simulation software used to visually explain a model is normally proprietary to the specific model equations and cannot be easily adapted to new models by non-programmers. Simulation software needs to be modular and based upon web technologies so that the software can be run on multiple platforms. The NLX simulation software is a group of Java-based objects that can be combined …
