Abstract in UndeterminedThis paper treats the hardware architecture andimplementation of mixed radix FFTs with cores of radix 3 andradix 5 in addition to the standard radix 2 core. The implementationflow graphs of the higher radix cores are presentedtogether with a description of how these cores afTect a pipelinedFFT implementation. It is shown that the mixed radix FFT ismore expensive than the ra

A reconfigurable digital root raised cosine (RRC) filter for a UMTS terrestrial radio access (UTRA) mobile terminal receiver is described and analysed. The filter monitors in-band and out-of-band received signal powers and calculates the appropriate filter length that meets the bit-energy to interference ratio (Eb/No). This design is advantageous, as only minimum battery power is used resulting in

Popular Abstract in Swedish Mekanisk ventilation kan medföra "ventilationsinducerad lungskada" (VILI), som kan öka sjuklighet och dödlighet i samband med akut lungskada (ALI). Flera ventilationssätt har föreslagits för att undvika VILI, men inte slutgiltigt utvärderats. En princip är att öka alveolär ventilation och CO2-elimination genom att minska ventilationen av de skadliga rummet, dead space. Ventilator-induced lung injury (VILI) may contribute to morbidity and mortality of acute lung injury (ALI). Lung protective ventilation (LPV), that reduces VILI, may involve low tidal volume (Vt). Particularly low Vt is possible if dead space ventilation is reduced e.g. by aspiration of dead space gas (ASPIDS). ASPIDS implies that gas rich in CO2 during expiration is aspirated through a separate c

Environmental aspects have during the last years made electric vehicles an interesting competitor to the present internal combustion engine driven vehicles. For a broad introduction of pure electric vehicles, a battery charging infrastructure is deemed necessary. However, to build and maintain such an infrastructure is costly. Active power line conditioning capabilities could be included in the ba

Popular Abstract in Swedish Kostfiber kallas de kolhydrater från växtriket som inte bryts ner under matsmältningen och därför når tjocktarmen i stort sett opåverkade. Kostfiber finns till exempel i våra fyra sädesslag, havre, råg, korn och vete, vilka alla är cerealier. Framför allt är det de yttre delarna av cerealiekärnorna, klidelen, som innehåller mycket kostfiber. I cerealier är de vanligasteIt is well known that dietary fibre is good for the health. Cereals, and in particular the outer parts of the cereal kernels, are rich in dietary fibre. Rye bran, wheat bran, oat bran and barley fibre have been investigated regarding their suitability as additives in low-fat meat products. Two types of meat products, frankfurter-type sausages and meatballs have been evaluated in this thesis. In th

In today's society, much energy is used and all energy use (e.g. heat, electricity) affects the environment. Greenhouse gas emissions from energy affect the climate of the earth and increase the natural greenhouse effect. Environmental impact because of energy use causes both local and global problems. Efficient energy use in buildings is a prerequisite for dealing with climate issues and in t

Arbetsrelaterade skador orsakar personligt lidande och ekonomiska förluster för både företag och privatpersoner. Repetitivt arbete och statiska arbetsställningar med armarna kan leda till belastningsskador i axel- och halsregionen. Detta examensarbete har haft som syfte att utveckla ett mjukt bärbart robotsystem med Bioservo Technologies Soft Extra Muscle (SEM) teknik, som ska ge assistans vid lyfWork related injuries causes personal suffering and economic loss for both companies and individuals. Repetitive work and static postures with the arms can lead to musculoskeletal disorders (MSD) in the shoulder and neck region. This thesis set out to develop a wearable soft robotic arm lifting system using Bioservo Technologies’ Soft Extra Muscle (SEM) technology. The objective was to develop a f

Väpnade konflikter är komplexa och mångfacetterade – män och kvinnors roller och nivå av inblandning varier avsevärt. Med detta i åtanke är det nödvändigt för internationell rätt och dess utövare att erbjuda ett reellt skydd, där ansvarsutkrävande och upprättelse erbjuds på lika villkor för alla oavsett kön. Risken är annars att vissa grupper osynliggörs. Sammanfattningsvis krävs det en nyanserad

En två-kolonn MCSGP process för upprening av Liraglutid genomfördes i laboratorieskala. Den här processen är inte en kommersiell uppreningsprocess, utan att den är ett modellsystem med en realistisk peptidblandning och med en icke-kommersiell harts. Först modellerades processen med en konvektiv dispersiv modell för att beskriva koncentrationen genom kolonnen och den steriska massaktionsmodellen föA twin-column MCSGP process for the purification of Liraglutide was implemented at lab scale. This process is not a commercial separation step, but it is a model system with a realistic peptide mixture and with a non-commercial resin. First, the process was modeled using a convective dispersive model to describe the concentration along the column and the steric mass action model to describe the ad

This master’s thesis report describes the development of a new system for control and monitoring of a helium liquefaction plant which has been carried out at Kryolab, Lund University. At the plant, helium gas is purified and then cooled in several steps until it condensates. The plant is very similar to the ones constructed today, but Kryolab wished to replace the outdated control system. The new

A model of the Swedish power plant Mälardalen Energi, developed by Solvina AB was simulated in Dymola with different types of control strategies in order to evaluate if they could improve the operational flexibility of the plant and, thus, its ability to deliver frequency control to the Swedish power grid. Several different control strategies and process modifications were tested and compared to p
