Design och konstruktion av mätuppställning för induktiv mätning av magnetisk spinndynamik

Development in spin dynamic occurs in the whole world because of therising demands on fast electronic storage for example hard drivesand RAM (Random Access Memory). Measuring the spin resonance of amaterial gives you the insight of the theoretical speed for amagnetic memory. This means the maximum storage speed is below thefirst resonance. All magnetic materials have different propertiesthat will inflict the resonance frequency which brings that theconstructors of memories need to know which magnetic material theywill use to obtain best results. In the market for normal users themaximum storage speed in a RAM memory is 1.6 GHz.

Implementation av fältbuss ASIC i FPGA

HMS Industrial Networks AB is in need of changing a communications solution that iscurrently based on an ASIC. This will be achieved by moving the communications solution toa FPGA with the help of the programming language VHDL. By doing this, it is possible toreduce the need for specific circuits, get a more flexible platform and thus get a cheapersolution.This report describes a solution for how to move a network protocol from an ASIC to anFPGA. The report shows that the network slave device is working under the guidelines forthis project. This means that it is quite realistic to implement a fieldbus protocol on an FPGA,using VHDL and to maintain the same functionality as the earlier communications solution..

Bibliotekarien som distansarbetare? : förutsättningar för bibliotekarien att utföra sina funktioner på distans

We studied how librarians would adapt to telework, the performance of job responsibilitiesfrom home. We found'that all duties could be accomplished. but to varied extents.Computerbased searches, interlibrary loans, acquisitions, indexing and telephone referenceservices are the duties most likely to adapt to telework whereas cataloguing andclassification probably are best performed in the ordinary workplace.Most duties would demand access to technical means of assistance when performed fromhome. Connections to the library's local network, directly or via modem, are requiredbecause it is unrealistic to expect librarians to telework with fewer tools than theyordinarily have available. Although librarians generally believe that teleworking will nothave a large irnpact on the operation of the library, most would like to telework.Whether teleworking is a viable strategy depends on the characteristics of the duties, thelibrarian's desire to telework, but also on the size of the library, the size of its staff, thelibrary's activities, and how work is distributed between librarians..

MEASUREMENT OF C-REACTIVE PROTEIN IN CANINE SERUM ON KONELABAUTOANALYZER 20

An inflammatory reaction is induced after release of proinflammatory mediators such asinterleukin 1 and 6 and tumour necrosis factor ?. These mediators stimulate the liver tosuppress the syntheses of albumin and endure the syntheses of acute phase protein forinstance C-reactive protein. The aim of this paper was to perform a method validation on animmune turbidimetric assay to quantify C-reactive protein in canine serum at the laboratory atSkara Animals Hospital, Skara, Sweden. The validation involved evaluation of the assaylinearity, precision, stability and recovery.The method was proved to be linear for both TruLab control and Medinor control.

Stress och genusspecifika mönster bland ungdomar : En kvalitativ studie utifrån professionella aktörers upplevelser och erfarenheter av ungdomars stress

The aim of the study was to understand professionals? perceptions and experiences of adolescent stress. In the study I interested myself further if you can identify gender-specific patterns in the professional stories about young people's stress and stress related illness. Five interviews were conducted with professionals in psychiatry and social work. The thesis took its incipience in social constructionism.

Tidssynkroniserade mätningar i vattenkraftstationer

Vattenfall and Svenska Kraftnät perform start-up tests, where hydropower generators are used to power up the electrical grid in case of a blackout. To monitor the electrical grid, Phasor Measurement Units (PMU) are used. Each PMU is individually equipped with a GPS-receiver to precisely timestamp the data relative to the official time UTC. During the test, it is also of interest to timestamp the measurement signals from individual hydropower generators to later compare with PMU-data, and thus study the power grids impact on the generator. The aim is to work out an appropriate method to make these measurements and to build a data acquisition system, capable of timestamp data relative to UTC, from a generator in one of Vattenfalls hydroelectric power stations. The problem is that the generator is located in an underground station which hampers the reception of GPS-signals and wiring should be avoided if possible. Time synchronization has been solved by using Vattenfalls network, which is synchronized by the network protocol NTP.

?Det finns någon slags Open Access där ute?. En idé- och ideologianalys av bibliotekariers förhållningssätt till Open Access vid sex forskningsinstitut.

The Open Access (OA) movement came to be as a reaction against the enclosure of information resources, facilitated by new distribution technologies. The purpose of the OA movement is to make research results freely available. The aim of this master´s thesis is to increase the understanding of how libraries outside of the academic sphere and within research institutes relates to OA. As a theoretical framework I created two different ideologies, the OA ideology and the nonsharing ideology. I also conducted six interviews with librarians.

Small-worlds och rich-clubs bland bloggar : En nätverksanalys av den svenska bloggosfären under FRA-debatten 2008

Purpose/Aim: To find power structures within the blog network.Material/Method: Using keywords to find all available blog posts about the National Defence Radio Establishment from the blog search engine Twingly, and thereafter using the same blog search engine to find inlinks from other blogs, to those posts. The data is set into the context of the small-world networks models of Duncan J. Watts and rich-club models of Sergi Valverde och Ricard V. Sole.Main results: 5183 unique blogs have written about the subject in 22779 blog posts to which 28128 inlinks from other blogposts are made. Just over one fifth of the blogs are linkted to each other in one big network, where the remaining blogs stand without any ingoing or outgoing links.

Det står ?jävlig mamma? skrivet i pannan på mig" : En kvalitativ studie om föräldrar till barn med diagnos inom autismspektrumet och deras vardag

All of the intervieweeswere mothers. The results showed that it is important to parentsto have contact with other parents who are in the same situation as them. Many of the interviewees had a small social network.

Att balansera Management Control Systems - En fallstudie av ett litet svenskt IT-företag

This thesis studies the concept of balance in the management control systems (MCS) of a small Swedish company within the IT-sector. The aim is to evaluate the importance of balance and dynamics in MCS and investigate which factors affect them. The frameworks used are Simons (1994) four levers of control, and the five-factor model for balance and dynamics by Mundy (2010). The small IT company - the object of the case study - has grown extensively in the last years and needs to develop more formal MCS without losing efficiency and creativity in their fast-moving industry. The case study reveals that balancing MCS is important also in smaller companies with less formal MCS.

Personlighet och konflikt - En studie om chefers personlighet, konfliktstil och Locus of control

Studiens syfte var att undersöka om det fanns skillnader i personlighet och val av konfliktstil beroende av vilken placering respondenterna hade i syskonskaran samt om Locus of control skiljde sig mellan olika åldersgrupper. Samband mellan chefers konfliktstil och personlighet undersöktes också. De 103 respondenterna som var mellan 25-75 år, 63% män och 37% kvinnor, besvarade en enkät som bestod av demografiska frågoroch arbetsrelaterade frågor om chefskap. Tre test användes; ett personlighetstest, RottersLocus of Control och Thomas-Kihlman?s konfliktstiltest.

Aspekter på återhämtning vid utmattningssyndrom samt hanteringen i återhämtningsprocessen : En kvalitativ undersökning i Kalmar län

The conception of exhaustion was first used in the end of 1960 and was then used in a psychological context directed towards the working life. Eventually was the conception devided into two main categories: mental and somatic symtoms. Today research of exhaustion is mainly aiming towards recovering and returning to working life.This work sets out to analyse the importance and effects of social networks such as family, friends and professional relations in helping people who suffer from exhaustion to recover. The study is based on interviews with eith people who have suffered from exhaustion but today are recovered. To my aid I have used tree different questions: What part have the social network of family and friends ment to the recovery? What part has the professional relationships with doctors, therapists and curators ment to the recovery? How have you changed your life in order to maintain balance?The interviews pointed out the importance of the social relationships as support, feedback and understanding that the process takes time.

Skiftarbetets påverkan på den upplevda stressen : - en undersökning inom vården

AbstractThe purpose with this study was to get knowledge if there are any possible differences in, and correlation between, experienced stress, experienced demands, experienced control and experienced social support in correlation to shiftwork.The study was made at two central hospitals in south of Sweden and had 90 participants (78 women and 12 men) that answered a questionnaire in the current variables. The result in experienced stress showed that there were no differences between shift workers. The results showed a difference between the day- and the nightshift in the correlation between control and stress. The writers speculates that the reason why the nightshift experience high stressvalues with high control can depend on the lack of presence by higher managers, compared with the dayshift. .

The mobility of employees within the EU, and the Eures Network

En sammanfattning av uppsatsen på maximalt 8000 tecken.This thesis is mainly dealing with the mobility of the employees within the borders of the European Union. Legislative framework from the EU is favourable and the Commission has set as one of it goals to promote the migration. Globalisation trends and contemporary business concepts need people who are mobile on the other hand. But migration numbers are still low within Europe. The purpose of this thesis is to find out how much the legal uncertainties, and the different culture mentality in the workplace of another country act as barriers in the minds of the people who wish to work abroad.

Identitetspresentation på Instagram : En studie i användares upplevelser och attityder till sin identitetspresentation på Instagram

In recent years, the internet has exploded of images. Not at least in the popular photo-sharing network Instagram as one of the fastest growing social network for the moment. Millions of people around the world share pictures and expose themself for friends and family. We were therefore interested in which experiences and attitudes users have towards their identities in relation to their self-image and self-presentation on Instagram. Furthermore, whether they in general have a primary interest in using Instagram as a tool to experiment with images to present their identity on Instagram, in which way they approach their Instagram follower?s expectations on how they present themselves on Instagram and if they are aware of any strategies in their self-presentation on Instagram.The result of this study is the fact that our respondents thinks that they do not intend to have a primary interest in experimenting with images on Instagram to present their identitiy, it is rather something that comes naturally in how they present themselves on Instagram.
