Popular Abstract in Swedish Trådlösa system som använder elektromagnetisk strålning, även kallat radio kort och gott, har fått ett enormt genomslag i våra liv. Radio används överallt: telefoni, GPS, mobilt bredband och TV är tillämpningar som vi som privatpersoner lätt kommer i kontakt med men även till radar, magnetisk resonanstomografi och andra avbildande system. Speciellt datakommunikation i mThis thesis investigates the opportunity of wireless multi-gigabit per second communication at the millimeter-wave (mmW) frequencies around 60 GHz by using impulse radio and nanoelectronics. Today most wireless communication take place in the microwave region, where several different systems and applications are crowding the narrow-band channels. Complicated schemes are applied in order to avoid i

I dagens samhälle blir befolkningen äldre och kraven på äldrevården ökar. Snabbare, mindre avslappnade och ovärdiga tvättmetoder används i större utsträckning såsom exempelvis duschning eller tvätt i sängen. Arjo strävar efter att öka badandet inom äldrevården och att inkludera en känsla av välbefinnande och avslappning, samt att badproceduren ska upplevas med värdighet hos vårdtagarna. Detta för Today, the population is getting older and the demand on long-term care facilities is increasing. Faster, less relaxing and undignified washing methods are more prone to be used, such as showering or in bed washing. Arjo strives to increase bathing and to include a feeling of wellness, making bathing a dignified and relaxing experience. This, in order to increase the quality of life for people fac

Abstract In Sweden many older closed municipal landfills lack current safety measures such as bottom liners and contain hazardous materials that are today strictly regulated or banned. Emissions from these pose a threat to health and environment now and in the future, having the potential to contaminate soil, groundwater, surface water and air. Risk for exposure is often increased due to poor doc

This essay describes the human relationship to the Swedish Agricultural open landscape, which is romanticised in popular culture, but is also seen by the anthropocentric hegemony in society as a landscape to use as resource for consumption and as symbol for “nature products”. The research deals whit the dualistic approach to cultural landscape by using a semiotic analyse of two food company brands

Utveckling av mätteknik för mätning av rörligheten i knäleder hos barn med Cerebral pares Cerebral pares (CP) är en neurologisk störning som kan leda till förlust eller nedsättning av de motoriska funktioner som påverkar kroppens rörelser, muskelkontroll, koordination och balans. CP kan orsaka obalanser mellan musklerna som kan leda till kontrakturer. Kontrakturer innebär att musklerna förkortas Cerebral Palsy, commonly referred to as CP, is a neurological disorder that results in loss or impairment of motor function, which affects body movement, muscle control, muscle coordination and balance. In Sweden, about 200 children are diagnosed with Cerebral Palsy every year and the disorder can cause imbalances between the muscles. These imbalances can lead to contractures which is equiva- lent

Glucagon was discovered in 1922 as a hyperglycemic factor in the pancreas. During its early history up to 1970, glucagon was shown to increase circulating glucose through stimulating glycogenolysis in the liver. It was also shown to be a constituent of islet non-ß cells and to signal through G protein coupled receptors and cyclic AMP. Furthermore, its chemical characteristics, including amino acid

L-DOPA-induced dyskinesia is a major problem in the treatment of Parkinson's disease. Today there are few anti-dyskinetic treatments available for the patients, and all of them have major limitations. Recent findings have revealed an important role of the serotonin system in L-DOPA-induced dyskinesia. In the parkinsonian brain, serotonin axon terminals can compensate for the dopamine loss by conve

An indoor localization system for positioning evacuating people can be anticipated to increase the chances of a safe evacuation and effective rescue intervention in case of a tunnel fire. Such a system may utilize prevalent wireless technologies, e.g., Bluetooth, RFID and Wi-Fi, which today are used to survey incoming and outgoing traffic to a certain space or location, to estimate group sizes and

Interstitial lung disease (ILD) encompasses a heterogeneous group of more than 200 con-ditions, of which primarily idiopathic pulmonary fibrosis (IPF), idiopathic nonspecific interstitial pneumonia, hypersensitivity pneumonitis, ILD associated with autoimmune diseases and sarcoidosis may present a progressive fibrosing (PF) phenotype. Despite different aetiology and histopathological patterns, the

The digital cellular systems era started about thirty years ago with the release of the first digital cellphones. These first digital cellphones were very different from today’s slim and esthetic cellular pocket computers. They were not mass-produced in million units a day, and they were designed for radio performance rather than appearance. Today, all components are integrated inside the mobile p

A Brain-Computer Interface (BCI) is a system that, in real-time, translates the user's brain activity into commands that can be used to control applications, such as moving a cursor on the screen. The translation is made possible by machine learning methods and other algorithms. The thesis focuses on EEG-based BCIs which are the most common type of BCIs due to EEG measurements being non-invasive,

Riskbaserad monitorering – ett sätt att säkerställa kvalitet i kliniska studier Kliniska studier undersöker effekter av medicinska behandlingar på människor. De är hårt reglerade för att säkerställa patientsäkerhet, det vill säga att försökspersonerna inte utsätts för onödiga hälsorisker, och för att säkerställa ett pålitligt studieresultat. Därför behöver alla processer och all data i varje studStudy quality is of paramount importance in clinical studies to ensure patient safety and reliable evaluation of the treatment, where the latter also entails the safety of future patients. Therefore, for example monitoring is required to minimise any risk of quality loss. Traditionally, the method for monitoring has been 100% source data verification which is costly and not sufficient. Today, auth

The most common way to develop System-on-Chip's (SoC) today is to utilize hardware design on a Field programmable gate array (FPGA). By utilizing the hardware on an FPGA, the opportunity to verify the hardware and start software design before implementing the final solution on silicon is possible. However, using an FPGA as a reference model for a final design gives a slightly imprecise estimat

Relationship marketing is getting more focus from researchers today. The idea of earning the trust and loyalty of customers by engaging in relationships has been put to practice in many retail areas. Retailers and researchers are stressing the importance of establishing relationships with their customers and are in many ways focused on the physical service encounter. Literature often suggests that

Reduction of the cleaning time is an important issue for companies using large tanks. A common solution is a stationary pipe going into the tank with a cleaning nozzle mounted on the end. Today the spray pattern of most cleaning systems is fixed. It would be beneficial to adjust the cleaning cycles so that the most soiled places of the tank get extra attention without increasing the total cleaning

As home care increases and care is moving from nursing homes and hospitals into people’s homes, there are problem areas that need to be addressed and solved in a better way than today. Nurses and other home care workers are exposed to serval risks when the patients’ home environment becomes their workplace. There are also serval risks for the patients when their homes are transferred into “small h

The relationship between Church of Sweden’s diocese of Lund and the Evangelical Church of the Church Province of Saxony in the German Democratic Republic started in 1983 and came to an end with the fall of the Berlin wall in 1989. The exchange-based relationship between the two churches started with a request from the church in East Germany, searching for allies and ecumenical contacts in Western

Endoscopic sinus surgery (ESS) is today a common method for the treatment of chronic rhinosinusitis. Assessment of the results has been based mainly upon subjective evaluation, and only a few reports present objective measurements, In the present study, the 133-xenon washout technique was used for preoperative and postoperative evaluation of paranasal sinus ventilation in 12 patients selected for

Nucleus is at the center stage of cellular drama orchestrated in the life of a cell and the nucleoplasm is surrounded by a double membranous compartment constituting the Nuclear membrane/envelope (NE) that separates it from the cytoplasm in nucleated cells. The initial understanding of the NE was that of a border security entity between the nucleus and the cytoplasm, separating gene regulation and

Detta examensarbete undersöker möjligheten att förbättra produktnivåmätningen i en av Tetra Paks fyllnadsmaskiner, eftersom den nuvarande lösningen inte detekterar den med den önskvärda precisionen, samt mätområde.
