In this Master thesis, microwave connections between circuit boards are constructed. The primary frequency band is the X-band (8-12 GHz). The purpose of the connections is to enable a more simple and cheaper way of mounting the circuit boards inside a container. The connections have been designed and evaluated, using different computer programs. A few prototypes have been built and measured.

The aim of this master thesis was to measure the terminological consistency when indexing fiction. The study included ten participants, five librarians and five patrons who indexed two novels in three steps. Besides calculating the terminological consistency a typified index based on the term frequency was created.Subject heading list Att indexera skönlitteratur was used as a controlled vocabulary and to calculate the consistency the asymmetrical formula was used.The result showed that the study produced relatively high consistency values compared to other studies. The subject heading list increased the consistency value for all of the participants, for the patrons the increase was substantial. The librarians produced higher consistency values compared to the patrons in almost every step and they had in percentage lower amount of terms used only once..

Övervikt och fetma är ett av de mest omfattande folkhälsoproblemen i Sverige och det är en stor andel barn och unga som lever med detta problem. Då goda matvanor grundläggs i tidig ålder utgör skolmåltiden en betydelsefull roll för att upprätta hälsosamma matvanor. Faktorer i den fysiska matmiljön, såsom möblering, städning, dekorering, inredning, belysning samt ljudnivå påverkar elevernas upplevelse av måltidssituationen. Den psykiska miljön som innefattar både psykologiska och sociala faktorer, det vill säga servering av skolmaten, arbetskläder, matglädje, elevernas matintag samt möjligheterna för skolmåltidspersonalen att gå någon fortbildning är även av betydelse för måltidssituationen. Dessa faktorer har studerats i detta examensarbete som utförts på uppdrag av Region Halland och som syftade till att studera skolmåltidspersonalens upplevelser av att påverka måltidssituationen i skolan.

In this paper we investigate how the possibility of mobility affects the frequency of blogposts andthe use of pictures in blogs and the content of the pictures. The purpose of this paper is toinvestigate what bloggers do with the possibility of mobility and how it effects the blog. Here weonly focus on smartphones. We focused our theory on communications and what mobility can offerto communication. To investigaste our subject we chose an combination of a qualitative and aquantitative study.

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.

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.

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.

Måltidsverksamheter inom offentliga sektorer har över 100 års historia där den svenska väl- färden har en stor betydelse med skatteintäkter som till exempel finansierar skolmåltiderna. Privata aktörer konkurrerar idag på marknaden för att få driva måltidsverksamheter inom of- fentliga sektorer. Genom att använda Mintzbergs organisationsteorier har vi undersökt om det finns organisatoriska skillnader mellan privata och offentliga måltidsverksamheter. När det gäller att studera ledarskapet har vi använt oss av fyra ledarskapsteorier: strukturella, HR, symboliska och det politiska ledarskapet. De tillsammans med FAMM (Five Aspectes Meal Model) ligger till grund för att visa om det finns samband mellan organisationen och ledar- skapet i måltidsorganisationer.

Radio Frequency Identification, RFID, is a convenient way to enable contactless identification which does not require any physical nor optical contact. As with any radio-based communication the signal can be intercepted, thus making the technology vulnerable to several kinds of attacks. Interception of communication is not the only threat. Since RFID tags might contain personal information or information that will grant the owner access to secure areas, skimming and spoofing attacks are also major threats against this technology. In this thesis report,  the perspective of an adversary is portrayed in an RFID-enabled environment by presenting where RFID is used and how it could be abused.

The purpose of this thesis is to examine the organizational buying behaviour in the purchase of travels abroad. We have conducted a case study of two companies, one medium sized and one larger. Our empirical studies have shown that the companies? buying process is divided into two types, the process of recruit a new travel supplier and the process of a straight rebuy of a regular travel service. In the recruiting process we found that the evaluation process of the purchase is an ongoing process that contradicts estab-lished theories.

Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..

Seventy-two working horses (they had been ridden with bit and bridle within the last two weeks) were examined in the oral cavity. Findings and status were noted. The horses were randomly chosen among individuals without clinical symptoms from the mouth and gastrointestinal system. The result showed that 93% of the horses had changes in the mucus membranes, 86% in the form of ulcerations. The P2 region was most commonly affected followed by wounds more caudally in the mouth (P3-M3 region).
