Knowing the droplets temperature is of great importance in spray-assisted combustion devices as it directly affects the droplet evaporation rate. This information helps optimizing the fuel/air mixture formation for the improvement of combustion devices. To measure the temperature of spray droplets, optical techniques such as Rainbow-Refractrometry (for point-wise) and the two-color LIF ratio therm

Virtual Reality (VR) as a complementary tool for medical practitioners in the assessment and rehabilitation of people who have suffered a traumatic brain injury (TBI) is discussed. A pilot-study has been undertaken on a prototype VR assessment tool. The design involved nine occupational therapists with expertise in the care of traumatic brain injured patients and one (computer experienced) patient

Euro50 is a proposed optical telescope with an equivalent primary mirrordiameter of 50 m. Partners of the collaboration are institutes inSweden, Spain, Ireland, Finland, and the UK. The telescope will have asegmented primary mirror and an aplanatic Gregorian configuration withtwo elliptical mirrors. For a 50 m telescope there would be noeconomical advantage in going to a spherical primary. The siz

Popular Abstract in Swedish Antalet människor som insjuknar i cancer (cancerincidensen) runtom i världen ökar, exempelvis i Sverige har antalet diagnosticerade tumörer ökat med i snitt 2.1% per år de senaste 20 åren. Denna ökning förklaras bland annat av vår ökade livslängd och vårt val av livsstil. Trots detta har antalet människor som dör i cancer minskat de senaste 20 åren. Dessa motsägelsefullThe continual increase in incidence of cancer has created an urgent need for improved methods for diagnosis, prognosis and/or treatment. In this context, the field of biomarker research has expanded immensely during the last few years. This thesis, based on four original papers, revolves around protein biomarker discovery in cancer. For this purpose, an in-house design recombinant antibody microar

In the mythological texts from Ugarit in modern Syria (probably 14th century BC), the motif of the deadly, drought-inducing sun plays a large part: the burning sun casts its destroying rays as a result of the power and influence of death, especially the god of death himself, Mot. However, the solar goddess Shapshu is in other cases portrayed as quite a benevolent entity. In this paper, I discuss t

Today embedded system development is a complex task. To aid the engineers new methodologies and languages are emerging. During the development the system is modelled using different tools and languages. Transformations between the models are traditionally done manually. We investigate the automation of this process, specifically we are looking at automatic UML to SystemC transformation. In this pa

By partitioning a hardware design into several blocks and adjusting the voltage of the different blocks individually, an overall power consumption reduction is possible. An algorithm and a hardware solution for assigning two supply voltages to a design divided into blocks is presented. The two supply voltages are optimized using an on-chip controller. The on-chip controller assigns one of the two

In this paper an OFDM timing synchronization ASIC is presented. The proposed synchronization unit can be used in any OFDM system. The algorithm is based on the correlation introduced by the cyclic prefix, which is exploited in the time domain where the time offset is estimated. Although the algorithm is too complex to be implemented on today's most powerful standard DSP, a hardware architecture th

A novel adaptive beamformer employing recursively updated soft constraints for acoustic speech enhancement is proposed. The beamformer operates in a subband structure to allow a time-frequency operation for each channel. Consequently, the processing performed can be viewed as a combined weighted spatial,frequency and temporal filter. The major benefit of the new recursive soft constrained beamformer
