Introducing distributed networks to designers: Development of an educational software tool and a methodology for its evaluation

Available connectivity in everyday objects has inspired design experts to develop methodologies for designing interactive environments - large-scale environments existing out of multiple embedded devices that interact with a user as if to be a single entity. The computer science community uses ad hoc distributed networks to accommodate scaling...

Wireless control of LED display lighting system using Bluetooth and Android

This thesis will describe our research and process during the Bachelor project "Wireless control of LED lighting system using Bluetooth and Android". Our team was a 4 man team, where we, the authors, worked on the Android app development, the PCB design and the Power Supply. For work done on an FPGA and the flexible LEDs, see thesis written by P...

A visual tool to elicit preference models; To enable support for interest based negotiations with the Pocket Negotiator

Negotiation is an important aspect of life. Especially interest based multi issue negotiation proved to generate better results for all the parties that are involved. Despite its importance, many people are not effective in negotiation. Therefore Negotiation Support Systems (NSS) are designed to aid users. The Pocket Negotiator (PN) is an...

Software Development Environments on the Web: A Research Agenda

Preprint of paper published in: Onward! 2012 - Proceedings of the 11th SIGPLAN symposium on New ideas, new paradigms, and reflections on programming and software, 19-26 October 2012; 10.1145/2384592.2384603 Software is rapidly moving from the desktop to theWeb. The Web provides a generic user interface that allows ubiquitous access, instant...

Natural and Flexible Error Recovery for Generated Modular Language Environments

Author's version of the work published in: ACM Transactions on Programming Languages and Systems (TOPLAS), 34 (4), 2012; doi:10.1145/2400676.2400678. Integrated development environments (IDEs) increase programmer productivity, providing rapid, interactive feedback based on the syntax and semantics of a language. Unlike conventional parsing...

Managing Software Design Erosion with Design Conformance Checking

Software design erosion is a well known process; however, once it becomes noticeable it may already have progressed so far that repairing it is difficult and costly. Design conformance assessment techniques can help developers to detect – and mitigate – the effects of design erosion, before they cause problems to the long-term maintainability of...

Methods and Techniques for the Design and Implementation of Domain-Specific Languages

Domain-Specific Languages (DSLs) are programming language aimed at a particular problem domain, e.g. banking, database querying or website page lay-outs. Through the use of high-level concepts, a DSL raises the level of abstraction and expressive power of the programmer, and reduces the size of programs. This dissertation covers various aspects...

Design, Simulation and Validation of Dual-channel Polarimetric Agile Radar Technology

In numerous radar applications, new problems concerning target detection in a clutter environment may occur. These problems cannot be solved using classical methods on the base of our current utilization of the reflection properties of various objects and their environment. Radar features that may assist in solving these problems are sought in...

Pure and declarative syntax definition: Paradise lost and regained

Syntax definitions are pervasive in modern software systems, and serve as the basis for language processing tools like parsers and compilers. Mainstream parser generators pose restrictions on syntax definitions that follow from their implementation algorithm. They hamper evolution, maintainability, and compositionality of syntax definitions. The...

Document Management System design architecture for interdepartmental organization

Our daily life is governed by rules, standards and policies, trying to guide our life as untainted as possible. This is also applicable to organizations. Often unity within organizations is achieved through management systems. Alongside management system are documentations, which form a vital aspect of the veins of the organization. Having a...

On the design and synthesis of voting games: Exact solutions for the inverse problems

In many real-world decision making settings, situations arise in which the parties (or: players) involved must collectively make decisions while not every player is supposed to have an equal amount of influence in the outcome of such a decision. The "weighted voting game" is a model that is often used to make such decisions. The amount of...

A Study of Synchronization Issues of Wavelet Packet based Multicarrier Modulation

Wavelet Packet based Multi-Carrier Modulation (WPMCM) offers an alternative to the well-established OFDM as an efficient multicarrier modulation technique. It has strong advantage of being generic transmission scheme whose actual characteristics can be widely customized to fulfill several requirements and constraints of advanced communication...

WebDSL: A Domain-Specific Language for Dynamic Web Applications

Preprint of paper published in: OOPSLA 2008 - ACM SIGPLAN Conference on Object-Oriented Programming, Systems, Languages, and Applications, 19-23 October 2008; doi:10.1145/1449814.1449858 WebDSL is a domain-specific language for the implementation of dynamic web applications with a rich data model. It consists of a core language with constructs...

Scheduling in high performance buffered crossbar switches

High performance routers are the basic building blocks of the Internet. Most high performance routers built today use crossbars and a centralized scheduler. Due to their high scheduling complexity, crossbar-based routers are not scalable and cannot keep pace with the explosive growth of the Internet. This dissertation studies a slight variation...
