Inverkan av tvång i gjutfogar och i betongkonstruktioner på
elastiskt underlag: Influence of Restraint in Casting Joints
and in Concrete Structures on Resilient Foundation
In this report, the risk of cracking in joints and/in adjacent concrete is estimated by checking shear forces in joints and the ratio between the actual maximum principal stress ant the actual strength of the concrete. The shear force has been estimated both by simple methods as well as by two-dimensional calculations. The risk of cracking in the concrete and/or in the joints is estimated with the computer program ConStre. The restraint from a resilient foundation or rock on a young concrete construction is estimated by a simple method that is exemplified. It is shown that the restraint can be neglected in some cases.
Belåning av aktier : har riskerna underskattats?
Investors? use borrowing as a way to profit from leverage advantages in their portfolios.When investors borrow with their securities as safety for the loan and the value of thesecurities decrease the investor can get a portfolio with more credit than what is covered bythe value of the securities and risk huge losses. To what extent an investor is allowed toborrow with his portfolio as safety depends on the bank or broker and varies between theproviders. By studying available material and in addition to that making an empirical study Iattempt to find out the reason for the varying degrees of leverage possibilities between thebrokers and how the degree of maximum borrowing on the securities are decided. Thefindings show that decision of leverage degree on a security is made after first making aquantitative analysis of the stocks volatility and liquidity and thereafter make a qualitativeanalysis of the company.

Produktionsutveckling av bastuaggregatsavdelning
To invent an optimized product is a complicated process. This process is only half of the work. It is equally important to develop a production system that can produce the product in an efficient and ergonomic way.After several evaluations of conceptual and detailed drawings a final idea has come to light.The idea intends, to the maximum extent, utilize the facility in a more efficient way through moving assembly lines and stations closer to the flock section and the stock for complete products. To make the production better, stations are placed in more logical places given the assignment they are supposed to accomplish. This improves the material flow radically.
Det mångkulturella biblioteket : En studie av invandrares biblioteksvanor vid Biskopsgårdens bibliotek i Göteborg
In this diploma work we present the results from a study of how adult immigrants utilise the services provided by the public library in Biskopsgården, Gothenburg. A survey encompassing 51 library visitors of foreign origin and an interview with two librarians at the library were performed.The results from the survey show that the majority of the informants were male students inages from 26 to 45 years and that they had been living in Sweden for a maximum of five years. 73% of the informants used the library to borrow literature in Swedish, 53% to read newspapers and periodicals in their native language, 43% to borrow literature in their native language and 43% to read newspapers and periodicals in Swedish.These results were compared with two other related studies with which partial correspondencewas found. In addition, related topics such as multicultural librarianship and the psychological aspects of immigration are discussed..
How to build a rein tension meter
A large part of the interactions between horse and rider during horseback riding takes place through the reins and the bit and devices for measuring the tension on the reins, rein tension meters, has fairly recently been developed. To safeguard the welfare of the ridden horse riders need to be aware of the rein tension they apply and actively work to decrease it. Furthermore, there is a need to develop the study of rein tension through new techniques and refined analysis procedures. A good-quality rein tension meter should be small in size, sensitive, durable and as accurate for light rein tension as for strong forces. Rein tension meters used in research on horse and rider interaction commonly depend on strain gauge technique for generating rein tension data.
Den livsmedelshygieniska kvaliteten hos franska opastöriserade dessertostar :
This study was performed to investigate the bacteriological quality of French cheeses made from raw milk. Fifty cheeses of this type were purchased from Swedish retail premises. The methods described by the Nordic Committee on Food Analysis (NMKL) were used to determine the number of Enterobacteriaceae, presumptive Escherichia coli, coagulase positive staphylococci and Listeria monocytogenes. In 32 cheeses (64%) the number of bacteria mentioned above exceeded the determined maximum value. Thirty samples (60%) showed high counts of Enterobacteriaceae.
Passivhus vid polcirkeln : Fungerar det?
This report is the product of the course AF101X, a bachelors degree in Samhällsbyggnad atKTH. The task of the course is to design a small house at a given location and also implement adeepening study. The house in this report is located in Kiruna in the north of Sweden, where theclimate is much colder than in the rest of the country.The deepening study of this report is to evaluates how realistic passive housing north of thePolar Circle is based on those facts. The house will to some extent be designed to fit the passivehousing standard.
Resursrelaterad informationshantering i uthyrningsverksamheter : En studie av verksamhetsstödjande IT-system och identifikationsteknologier
The management of assets in organisations today can be a challenging task and optimising their usage is critical to ensure maximum profit. For rental businesses offering tangible products efficient management of movable assets are an essential part of the business strategy. The main purpose of this study is to investigate how asset management and asset information management can be carried out in rental businesses and in what ways information technology can support it. By doing a literature review combined with a case study where three rental businesses and their use of information technology were examined we could identify several important aspects regarding asset information management. The results we have found is that rental businesses with a high degree of digitization in existing asset information management systems are able to rationalize existing work processes, which in some ways changes the roles of employees.
Äggstockens normala storlek och struktur hos tik :
There are only a few published studies on the normal variation in ovary size in bitches. All of the previous studies have been made on the beagle breed. This study was performed on indian street dogs with the objective to measure ovaries and structures in the ovaries after ovariehysterectomy to decide if smaller dogs have smaller ovaries and how small and big they can be in the normal dog. The structures (follicle and corpus luteum) where also measured to get a maximum size for normal structures in the bitch. This information can be valuable when examining the ovaries of the bitch with ulstrasound.
Hur påverkas aktieavkastningens volatilitet när optionshandel införs?
Denna uppsats undersökte effekten av en optionsintroduktion på den underliggande aktieavkastningens volatilitet. Tidigare studier som gjorts i frågan visade på olika resultat. Denna studie utgick från en artikel av Bollen (1998). En modifierad marknadsmodell användes för att analysera det eventuella sambandet mellan optionsintroduktion och skift i aktieavkastningens volatilitet. Parametrarna i modellenskattades med maximum likelihood.
Experimentell undersökning av provkroppar för trälimfogar
This thesis engages the topic of test methods for wood adhesives. Two test methods were evaluated, EN 302-1, a European standard, and ASTM D905, an American standard. The total amount of specimens manufactured and tested was more than 500. The adhesive bonds were tested in shear with an increasing load on the specimen until failure.The adhesives used were epoxy-resin, phenol-resorcinol-formaldehyde and a 2-K polyurethane. The test programme included five different types of intentional errors per method, in order to investigate the sensitivity of the test methods.
Att göra analoga objekt digitala : En kvalitativ studie om digitaliseringsprocessen i ett bibliotek
Contemporary libraries face challenges in transforming their organization to meet the digitalized society. To develop the process of digitization of literature is a natural way for libraries to go when they already have more visitors online than physically. Since the demand for digital material is so sought after, we feel challenged to address the challenges of the Internet as an emerging functional medium for distributing knowledge. These developments will be able to significantly modify the nature of literature as well as the existing system of quality assurance. In this study, we explored and analyzed a digitization project at a research library.
Reglering av veka strukturer med multipla sensorer
In this master thesis, control algoritms using arm side sensors are investigated for an industrial robot. The sensors can be position encoders placed after the gearbox and accelerometers on the robot arms. Control strategies are discussed and evaluated for different models of the robot, after which chosen strategies are applied to a realistic model. Control algoritms using arm side sensors (LQ, dual-loop and PD-PID) are compared to a PID-controller that only uses measurements of motor position for feedback control. The comparison are done with respect to disturbance rejection, oscillation damping, robustness and tracking performance of a reference trajectory.
