Vad spelar vi för roll? En studie om bibliotekariers syn på utvecklingen inom biblioteksfältet och sin egen yrkesroll vid svenska bibliotek
The aim of this bachelor?s thesis is to gain deeper knowledge about how librarians in public libraries in Sweden view theirprofessional role with regard to the last decades of change in the library field. Especially concerning the technical evolution and towards a higher user orientation and market mindset, and in which ways this has influenced the librarians everyday working tasks. A particular focus has been placed towards the reference transaction, the use of computers and e-media, and the stock development. We believe that there currently is a changeover, from the libraries traditional line of function, towards them as more of service institutions.The method used in this study for answering the research questions and to gather empirical information is semi-structuredinterviews.
Bootstrapvalidering av konfidensintervall för ett standardiserat mått för att jämföra behandlingsbenägenhet mellan sjukhus
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.

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.
Industriellt köpbeteende av utlandsresetjänster
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.
Könade argument i vårdnadstvister : En studie av argument i vårdnadstvistsdomar från 2011
The purpose of this study was to highlight LGBT asylum-seekers experiences of expressing their sexual identity or gender identity in the country of origin and in the asylum process in Sweden. By interviewing people who got permanent residence in Sweden because of gender or sexual orientation in Utlänningslagen (2005:716) we have been able to explore their own experiences from expressing themselves. This study analyse these experiences from a social psychological perspective, from this analysis we aimed to obtain a deeper understanding of how the experiences from the country of origin affects on the experiences in the asylum process. This study shows that LGBT asylum-seekers often is facing negative reactions from the environment in the country of origin, these reactions can limit their possibilities to express their sexual identity or gender identity in the asylum process in Sweden. The negative reactions they experience in the country of origin have contributed to that many LGBT people internalize feelings of fear to express themselves, feelings that often stays when they come to Sweden to seek asylum.
Segmentering och klassificering av LiDAR-data
With numerous applications in both military and civilian life, the demand for accurate 3D models of real world environments increases rapidly. Using an airborne laser scanner for the raw data acquisition and robust methods for data processing, the researchers at the Swedish Defence Research Agency (FOI) in Linköping hope to fully automate the modeling process.The work of this thesis has mainly been focused on three areas: ground estimation, image segmentation and classification. Procedures have in each of these areas been developed, leading to a new algorithm for ground estimation, a number of segmentation methods as well as a full comparison of various decision values for an object based classification. The ground estimation algorithm developed has yielded good results compared to the method based on active contours previously elaborated at FOI. The computational effort needed by the new method has been greatly reduced compared to the former, as performance, particularly in urban areas, has been improved.
Relation mellan optimism, self-efficacy och självskattat hälsotillstånd hos kvinnor och män
Tidigare empirisk forskning förevisade samband mellan optimism och hälsa, likaså mellan self-efficacy och hälsa. Föreliggande undersöknings syfte var att utifrån könsskillnader mellan kvinnor och män undersöka hur optimism och self-efficacy samverkar med deras självskattade hälsotillstånd. Deltagarna var 190 högskolestudenter, varav 113 kvinnor, i Mellansverige. Statistisk analys utfördes genom t-test, multipel linjär regressionsanalys och jämförelse mellan korrelationskoefficienter. Mätinstrumenten Life Orientation Test?Revised, General Health Questionnaire och General Self-efficacy Scale, samt ett påstående om fysisk hälsa användes.
Optimering av ultraljudssändare- och mottagare avseende räckvidd, strålningsvinkel och energiförbrukning
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..

Munhålestatus hos arbetande hästar :
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).
Skyltningen i Stockholms innerstad : Är den användbar för turister?
The purpose of this essay is to investigate if signage for tourists in Stockholm is enough to easily find your way to attractions and public modes of transport and how the city works with the issue. Triangulation was chosen for the essay, that is, a mix of qualitative and quantitative methods. A survey of 100 tourists was carried out in the Old town of Stockholm and interviews were made with stakeholders in the tourism industry and signage policy in Stockholm. The survey showed that most of the tourists found it easy to find their way in Stockholm and that they were content with the signage. Few of the tourists thought it was difficult to find their way in Stockholm.

Hur påverkas beteende/känslor och fysiologiska faktorer på människa och häst vid interaktion mellan parterna? :
The aim of these two studies was to investigate the possible physiological, behavioural and emotional changes that appear after human-horse interactions and also to find an explanation to why they occur. One aspect that is discussed is whether the wellbeing of humans can be coupled to interacting with horses and of how the animals respond to the interaction. The first study was performed on 9 horses and their owners, both parts being subjects to registrations during 4 different interaction treatments. The second study was performed on 6 horses with registrations only being performed on the horses during 2 different treatments.
Nine horses underwent 3 different treatments all performed by their owners (H = stroking of the horses forehead, B = brushing and M = stimulation of the withers) in addition to a control round (K). Each treatment lasted for 4 minutes but observations were performed until after 45 minutes from start.
Att välja bok i biblioteksmiljön: En studie av hur bibliotekens exponering av litteratur påverkar biblioteksanvändarnas val
The aim of this bachelor thesis is to describe in part the public library users?process when deciding which books to borrow. Focus is on the library users?experience of the process and how literature exposure can support them intheir choice of book. This study seeks to find out to what extent choices arespontaneously made at the library, which elements of exposure that the userfinds helpful in the process and which factors usually influence the user infinding new things to read.The data was gathered through 100 structured interviews with public libraryusers.
Fälttest av en ny metod att med objektiva mätmetoder karaktärisera egenskaperna hos ridunderlag- en pilotstudie. :
Background
Research concerning footing and its contribution to injuries has been conducted primarily in racing Thoroughbreds. Studies in UK and Japan indicate that some specific factors could be responsible for an increase in performance-associated injuries. Researchers in Sweden have performed studies on Standardbred trotters. More research is needed to be done on equestrian sports since requirements on footing are not exactly the same in riding and trotting horses.
The lack of scientific evidence on the construction of equestrian surfaces has lead to anecdotal validation of designs.
