Den här högskoleavhandlingen beskriver designen av ett IF-filter samt hårdvarukonstruktion av en ny 77 GHz FMCW-radar demonstrator. Syftet med demonstratorn är att illustrera hur kisel germanium-, SiGe, teknologi kan användas istället för den mer vedertagna men dyrare gallium arsenik-, GaAs, teknologin. Den gamla radar-prototypen vilken Acreo AB utvecklat är funktionell men behöver konstrueras om för att bättre kunna utvärdera radarprestandan. I avhandlingen presenteras grundläggande radarteori och ekvationer för att underlätta förståelsen av de olika systemblocken. Rapporten beskriver också systemarkitekturen och hur dess funktionalitet kommer att testas.

Att perceptuellt uppfatta och identifera lukter påverkas av en rad olika kortikala system och kognitva förmågor. Syftet med föreliggande studie var att undersöka huruvida personer med afasi har en luktförmåga som skiljer sig från normalpopulationen och ifall en afasiproblematik påverkar de faktorer som normalt involverar luktförmågan.         I studien medverkade tio försökspersoner, sex män och fyra kvinnor. Personerna hade varierande grad och typ av afasi och var mellan 42 och 76 år. Deltagarna delades in i åldersgrupper där två personer klassades som yngre och åtta som äldre. Samtliga testdeltagare genomförde två olika lukttest: Odor Threshold Test (OTT), och Swedish Odor Identification Test (SOIT).

Our report procedure identification of instability and disturbance in an automatic manufacturing line of processing and assembling of chair sliding rails at Sapas manufacturing department in Vetlanda.To obtain a stabile ground we have mapped the material flow to receive a comprehensive view and to visualise connections.We have examined cycle times at different stations in purpose to identificate bottlenecks. The result of our examination showed that the bottleneck of the line was the brush station. This leads to that the expected bottlenecks identificated by Sapa gets a delay time and by that a longer cycle time.Interruptions has a clear negative influence at the line performance so we have also assemble data through the operators report list and compiled these in order to find out the interruptions effect on the line. The outcome during our assembled period was that the reported interruptions corresponded about 30 percent of the total available production time. This has a clear negative effect on the line productivity and efficiency as we have calculated in order to get the present status..

The aim of this study is to examine the opinions of eight 12-year old boys and girls about two comics; Sabrina ? tonårshäxan (Sabrina ? teenage witch) and Spiderman. Do children see gender differences in the two comics? Do boys and girls identify with the heroes in the comics and does this affect the children's own gender socialisation. We interviewed four boys and four girls from different parts of Sweden.

This is a descriptive paper based on a questionnaire- and literature study regarding how dogs are trained, what type and frequency of injuries that occur as well as how the dogs are best prepared for work. Using the results from the questionnaire, an overview is given on how members of Working dog clubs train their dogs and what kind of injuries that occur most frequently. The average age among the dogs included in the study was only about three years. This could indicate that older dogs are not trained in the same extent as young dogs. The results show that only a third of the dog owners warmed up their dogs before training.

The aim of this report is to discuss computer security in handheld computers and to find out the appropriate security level that must be implemented to be able to use handheld computers within the Swedish healthcare system. Most healthcare centers are using some kind of electronic journals for their patient´s data today, but there are still a number of clinics that are usingthe old paper-system. On a few places in Sweden the use of handheld computers at the clinics has already started, but in the United States the use of handheld computers in the medical area is already widespread and from this we can see a lot of different situations where it is useful and effective to work with handheld computers. The security demands on patient´s journals are high and regulated in both Swedish law and regulations from the National Swedish Board of Health and Welfare. The law does not have any substantial demands, but states that there should be an adequate security level based on the nature of the information and the costs.

Syftet med studien är att undersöka till vilken utsträckning människor upplever att de påverkas av media i sina attityder och åsikter kring politik, Och studera åldersskillnader mellan åldersgrupperna 18-25 och 65+. Vi ville även undersöka vilken inverkan medias politiska rapportering har på respondenterna. Det gjordes en kvantitativ undersökning i form av en enkätstudie. Enkäter delades ut till 104 respondenter, 52 i åldersgruppen 18-25 och 52 i åldersgruppen 65+. Resultatet visade att det finns vissa ålderskillnader i hur espondenterna upplever påverkan från media i sina politiska åsikter.

This essay attempts to examine whether it is possible to find a mutual understanding of the concept of drive between Spinoza?s philosophy and Freud?s psychoanalytical theory. Former texts on this subject have given a variety of conclusions: from a radical separation between the two authors to a complete identification between the two. The drive, or the desire which is the term Spinoza uses, has in Spinoza?s philosophy its foundation in the concept of conatus.

The object of this master thesis was to examine the significance of fairy tales for children and the extent which children today are able to share fairy tales through the activity of the libraries. The main question was: how current were fairy tales at the investigated libraries activity for children and how current were fairy tales in todays book publication? The qualitative methods used were in the form of interviews, statistics and source studies. The theoretical literature in this thesis described the folkloristic context of the fairy tales. There was also a psychological and a pedagogical view of the possibility of the fairy tales.

Music has always been an important form of communication and it can be found in many different contexts including aesthetical, cultural and emotional forms. In the globalized society of today music can be distributed fast through radio, TV, CD: s and the Internet. For many people consumption of music is an important part of the daily life and it can contribute to shape an individual?s attitudes and personality.The main purpose of this study is to find out whether there are any differences between men and women?s musical preferences. I will apply an explorative approach using qualitative interviews to describe what causes the differences.

This master thesis focuses mainly on the concept of quality and how the librarians responsible for phonogram purchase use it. The main object is to investigate how the librarians responsible for the purchasing of phonogram works when in the process of selecting the phonograms and how they speak about the concept of quality. Based on this main object four problems has been addressed. The empirical material is interviews made with the seven librarians responsible for phonogram purchase at seven Swedish libraries. The result of this investigation is analyzed based on a theoretical framework created by Sanna Talja, which focuses on what a phonogram collection should contain.

The overall aim of this study is to gain an understanding of how student?sexperiences influence their perceptions about the use of alcohol during the study years. We focused on various factors that might have an impact on the individual?sperception and alcohol intake. These are: environmental influences such as family, school and friends and their dominant norms, context such as place and time in life and how individual and social identity affects student?sperceptions.

I denna uppsats har jag undersökt hur  Harold Campings domedagsrörelses, ?Campingitismens? och därmed radiostantionsnätverk Family Stations Inc.s, religiösa föreställningsvärld ser ut som de sprider världen över.Undersökningen går igenom frågorna: (1) vem är mannen bakom profetian om den 21 maj 2011?, (2) vilka är Harold Campings centrala läror och vad grundar de sig på?, (3) på vad grundar sig hans profetia om Jesu återkomst den 21 maj 2011?, (4) vad är hans föreställning om frälsning och hur kan man realisera detta mål?, (5) hur skiljer sig ?Campingitismens? frälsningsläror från Heaven?s Gates eller finns det några likheter mellan dem? (6) vad är det som lockar folk till ?Campingi-tismen??89-årige amerikanen, Harold Camping verkställande chef och grundare av USAs nittonde största radiostationsnätverk  Family Stations Inc., kallad Family Radio tolkar Bibeln samt profeterar om domedagen på sitt allegorisk sätt genom sina radiosändningar, internet, satellit TV och sina 30-tal böcker och häften runt om i världen. Hans mening tycks vara att evangelisera var och en här på jorden. Utan att ha någon teologisk utbildning verkar han ändå kunna sin Bibel från pärm till pärm.Campings centrala läror hänger strikt ihop med Bibeln, den är den enda ultimata sanningen som ska lydas ordagrant. Hans förhållande till religion, till ett kristet liv och Bibeln har kalvinistiska influenser och fundamentalistiska drag enligt min uppfattning.

In this thesis some different modulation schemes for xDSL-techniques are compared. The investigated techniques are ADSL, G.lite, ADSL2, HDSL, SHDSL and VDSL. The modulation methods used are DMT, CAP and different versions of PAM. Several broadband techniques also use Trellis Coded Modulation (TCM) to increase the coding gain of the transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7.
