Affective Computing For Emotion Detection Using Vision And Wearable Sensors, Alphonsus Keary

PhDs

The research explores the opportunities, challenges, limitations, and presents advancements in computing that relates to, arises from, or deliberately influences emotions (Picard, 1997). The field is referred to as Affective Computing (AC) and is expected to play a major role in the engineering and development of computationally and cognitively intelligent systems, processors and applications in the future. Today the field of AC is bolstered by the emergence of multiple sources of affective data and is fuelled on by developments under various Internet of Things (IoTs) projects and the fusion potential of multiple sensory affective data streams. The core focus of …

Optimization In Multi-Agent Systems : Structures And Procedures, Ingo Stengel

Theses

The main advantage for the use of agent technology is in the capacity of agents to represent the interests of individual entities and to act autonomously on their behalf. In multi-agent systems this involves communication, coordination and negotiation.

The focus of this dissertation is to find ways to optimize multi-agent systems at different levels by taking into consideration their structure and the procedures used. As optimization depends to a large extent on the problem to be solved, group forming scenarios, in which self-interested agents compete to form and join groups, have been selected here for consideration. Optimization issues are discussed …

Personal Information Management. A Framework For Development Of Personalisable Web Based Services, Christopher Fuchs

Theses

The thesis research proposed herein will model, analyse and implement strategies for the development of personalised services. The goal of the research work is to design and implement a framework which supports developers by minimising the effort required in implementing personalised services. This includes the ability to react to localisation changes and to present proper information. An overall design goal is the independency of most components from each other which will be attained through the use of standard technologies and protocols and the consistent use of a component model. The result will include the proposed framework and the analyses of …

A Service-Based Architecture For Learning Management Systems Which Supports Personalisation And Collaboration, Markus Schmid

Theses

This work develops a service-based architecture for an extensible and customisable learning management system (LMS) runtime environment. The architecture mainly defines interfaces for the interaction of functional system components represented by loosely coupled distributed services. Services that represent functional components of the distributed LMS are called e-leaming services. In addition, underlying infrastructure services provide supportive functionality such as service-lookup within an institution. Users access the system using an LMS portal component that acts as a front-end for the LMS services.

While existing e-leaming environments provide a relatively good coverage of most of the functional requirements defined in this work, they …

Enterprise Business Objects : Design And Implementation Of A Business Object Framework, Kai-Uwe Schafer

Theses

Software components representing business entities like customer or purchase order introduce a new way of Online Transaction Processing to business applications. Collaborating business objects allow to complete whole business processes as a single distributed transaction, instead of dividing it into queued steps, which sometimes even require user intervention. This IS due to the fact that business objects contain both business data and logic and that they incorporate multiple databases from different vendors and different geographic locations in a single transaction.

Business objects cannot be used as stand-alone components, but require a framework of services that manage persistence, concurrent transactions, and …
