This thesis investigates possibilities to perform image interpolation on an FPGA instead of on a graphics card. The images will be used for 3D display on Setred AB’s screen and an implementation in firmware will hopefully give two major advantages over the
This thesis is centered around the problem of broadcast encryption. It considers a setting with one or more senders wanting to securely distribute messages, using a one-way broadcast channel, to a selected set of receivers.This can be achieved using encryption and one
This thesis presents a method for increasing the accuracy of an industrial robot by integrating a high accuracy measurement system in a feedback control loop. The performance of the system is evaluated on reconfiguring of ART modules and robotic drilling. Today robots
The Internet and the Web provide an environment for business-to-business and business-to-consumer exchanges in a virtual world where distance means very little, providers can advertise their products globally and consumers from all over the world can obtain access to these products. The
Unlicensed Mobile Access (UMA) provides transparent access to 2G and 3G networks for Mobile Stations over the unlicensed radio interface. Unlicensed radio tehnologies such as Bluetooth or WLAN technology connects the Mobile Station to the fixed IP network of the home or
This thesis investigates the IEEE 802.11b standard that describes radio communication for networks. The standard is carefully explained and the limitations of the standard are presented. To put the system in its context and to study the effects from the frequency translation,
Designing usable Graphical User Interfaces (GUIs) is a complex process and requires at least two things: knowledge of known GUI design principles and guidelines, and knowledge of structured methods for achieving usability.The purpose of writing this thesis was to investigate whether a
The problem of topology control and routing of bandwidth-guaranteed flows over wireless optical backbone networks is addressed. The input is a potential topology and a traffic profile. The constraints are that of limited interfaces at each node and the limited link bandwidth…
This Master thesis proposes a solution to manage variabilities of software product line applications. The objective of the research is to support software decision makers in handling additional software complexity introduced by product line architectures. In order to fulfill this objective an
Revocation in sensor networks is a challenging problem because asymmetric key cryptosystems are unsuitable for use in resource constrained sensor nodes. We present some properties of node revocation in distributed sensor networks (DSN) and explain their implementation… Contents 1 Introduction 1.1 Organization
