Multi-Agent Systems

A multi-agent system (MAS) is a system composed of multiple interacting intelligent agents. Multi-agent systems can be used to solve problems which are difficult or impossible for an individual agent or monolithic system to solve. Agent systems are open and extensible systems that allow for the deployment of autonomous and proactive software components. Multi-agent systems have been brought up and used in several application domains

Facilitating Flexible Link Layer Protocols for Future Wireless Communication Systems

This dissertation addresses the problem of designing link layer protocols which are flexible enough to accommodate the demands offuture wireless communication systems (FWCS).We show that entire link layer protocols with diverse requirements and responsibilities can be composed out of reconfigurable and reusable components.We demonstrate this by designing and implementinga novel concept termed Flexible Link Layer (FLL) architecture.Through extensive simulations and practical experiments, we evaluate a prototype of the suggested architecture in both fixed-spectrumand dynamic spectrum access (DSA) networks. FWCS are expected to overcome diverse challenges including the continual growthin traffic volume and number of connected devices.Furthermore, they are envisioned to support a widerange of new application requirements and operating conditions.Technology trends, including smart homes, communicating machines, and vehicularnetworks, will not only grow on a scale that once was unimaginable, they will also become the predominant communication paradigm, eventually surpassing today's human-produced network traffic. In order for this to become reality, today's systems have to evolve in many ways.They have to exploit allocated resources in a more efficient and energy-conscious manner.In addition to that, new methods for spectrum access and resource sharingneed to be deployed.Having the diversification of applications and network conditions in mind, flexibility at all layers of a communication system is of paramount importance in order to meet the desired goals. However, traditional communication systems are often designed with specific and distinct applications in mind. Therefore, system designers can tailor communication systems according to fixedrequirements and operating conditions, often resulting in highly optimized but inflexible systems.Among the core problems of such design is the mix of data transfer and management aspects.Such a combination of concerns clearly hinders the reuse and extension of existing protocols. To overcome this problem, the key idea explored in this dissertation is a component-based design to facilitate the development of more flexible and versatile link layer protocols.Specifically, the FLL architecture, suggested in this dissertation, employs a generic, reconfigurable data transfer protocol around which one or more complementary protocols, called link layer applications, are responsible for management-related aspects of the layer. To demonstrate the feasibility of the proposed approach, we have designed andimplemented a prototype of the FLL architecture on the basis ofa reconfigurable software defined radio (SDR) testbed.Employing the SDR prototype as well as computer simulations, thisdissertation describes various experiments used to examine a range of link layerprotocols for both fixed-spectrum and DSA networks. This dissertation firstly outlines the challenges faced by FWCSand describes DSA as a possible technology component for their construction.It then specifies the requirements for future DSA systemsthat provide the basis for our further considerations.We then review the background on link layer protocols, surveyrelated work on the construction of flexible protocol frameworks,and compare a range of actual link layer protocols and algorithms.Based on the results of this analysis, we design, implement, and evaluatethe FLL architecture and a selection of actual link layer protocols. We believe the findings of this dissertation add substantively to the existing literature on link layer protocol design and are valuable for theoreticians and experimentalists alike

Development of actuated Tangible User Interfaces: new interaction concepts and evaluation methods

Riedenklau E. Development of actuated Tangible User Interfaces: new interaction concepts and evaluation methods. Bielefeld: Universität Bielefeld; 2016.Making information understandable and literally graspable is the main goal of tangible interaction research. By giving digital data physical representations (Tangible User Interface Objects, or TUIOs), they can be used and manipulated like everyday objects with the users’ natural manipulation skills. Such physical interaction is basically of uni-directional kind, directed from the user to the system, limiting the possible interaction patterns. In other words, the system has no means to actively support the physical interaction. Within the frame of tabletop tangible user interfaces, this problem was addressed by the introduction of actuated TUIOs, that are controllable by the system. Within the frame of this thesis, we present the development of our own actuated TUIOs and address multiple interaction concepts we identified as research gaps in literature on actuated Tangible User Interfaces (TUIs). Gestural interaction is a natural means for humans to non-verbally communicate using their hands. TUIs should be able to support gestural interaction, since our hands are already heavily involved in the interaction. This has rarely been investigated in literature. For a tangible social network client application, we investigate two methods for collecting user-defined gestures that our system should be able to interpret for triggering actions. Versatile systems often understand a wide palette of commands. Another approach for triggering actions is the use of menus. We explore the design space of menu metaphors used in TUIs and present our own actuated dial-based approach. Rich interaction modalities may support the understandability of the represented data and make the interaction with them more appealing, but also mean high demands on real-time precessing. We highlight new research directions for integrated feature rich and multi-modal interaction, such as graphical display, sound output, tactile feedback, our actuated menu and automatically maintained relations between actuated TUIOs within a remote collaboration application. We also tackle the introduction of further sophisticated measures for the evaluation of TUIs to provide further evidence to the theories on tangible interaction. We tested our enhanced measures within a comparative study. Since one of the key factors in effective manual interaction is speed, we benchmarked both the human hand’s manipulation speed and compare it with the capabilities of our own implementation of actuated TUIOs and the systems described in literature. After briefly discussing applications that lie beyond the scope of this thesis, we conclude with a collection of design guidelines gathered in the course of this work and integrate them together with our findings into a larger frame

Crossroads 2000 Proceedings, 1998

Crossroads 2000 was the second biennial transportation research conference cosponsored by the Center for Transportation Research and Education (CTRE) at Iowa State University and the Iowa Department of Transportation. This proceedings is the set of papers presented at the conference. Twenty-five categories of papers were presented in five concurrent sessions. Reflecting the increasingly critical role of intelligent transportation systems (ITS) in maintaining and enhancing transportation safety and efficiency, one category in each concurrent session addressed an area of ITS. However, papers were included from all areas of interest, ranging from transportation infrastructure design to transportation policy. The proceedings contains 58 papers

Annual Report of the University, 1968-1969, Volumes 1 & 2

At least once every ten years the University of New Mexico has a chance to see itself as others sec it. The opportunity is provided by its accrediting agency. Routinely every decade, the North Central Association of Colleges and Secondary Schools sends a team of scholars and administrators to campus to determine whether the University is maintaining the prerequisites to continuing accreditation as a doctoral degree granting institution. While the examination is scheduled routinely, it is by no means a routine visit. The visitation team probes such areas as curricula, library, finances, administration, day-to-day operations, and long-range plans. Its report, much like that of an auditor, helps provide operational guidelines for succeeding years. The University of New Mexico in 1969 underwent its decennial examination by the North Central Association. The team of visitors prepared a comprehensive report touching on many areas vital to the University\u27s future. Findings of the committee and the University\u27s responses to them serve as the basis for this annual report of the President
