A problem when testing timeliness of event-triggered real-time systems is that response times depend on the execution order of concurrent tasks. Conventional testing methods ignore task interleaving and timing and thus do not help determine which execution orders need to be exercised to gain confidence in temporal correctness. This thesis presents and evaluates a framework [...]
Streamline Communications in Radiology
The background to the study was Unified Communications (UC), defined as Communications integrated to optimize business processes. A case study design is used to develop a LoFi-prototype. The prototype investigateswhat components an integrated communication solution should provide,for the people in radiology. The design was inspired by consumer products like Skype. In these consumer products were [...]
3D Visualization for Model Comprehension at Ericsson AB
With growing size and complexity of models, model comprehensibility has become a problem in model driven development. Common experiences are information overload in diagrams and difficulties in understanding model hierarchies, both leading to users spending too much time on comprehending models. The paper presents a case study at a department at Ericsson AB, experiencing this [...]
Achieving Safe DICOM Software in Medical Devices
This paper reports on an investigation on how to produce a reliable software component to extract critical information from DICOM files. The component shall manipulate safety-critical medical information, i.e. patient demographics and data specific to radiotherapy treatments including radiation target volumes and doses intensity. Handling such sensitive data can potentially lead to medical errors, and [...]
High speed data collection with Blackfin DSP
This report covers a master thesis in embedded systems, the goal of which was to investigate the high speed data collection capabilities with a Blackfin DSP. Basic theory about sampling and noise is covered briefly from a practical point of view. The theory is intended to be useful for those diving into a ADC datasheet [...]
