Gravitationslinser

Gravitational lenses are unlike ordinary optical lenses, a phenomenon corrupting our optical view of the cosmos. When we look out intospace we see celestial bodies lying with astronomical distance from Earth. There is no guarantee that what we see out there in space is actually there where we are observing it, and it may be that we see multiple images of the same star! Studies have shown that thenumber of distorted images of an n-mass (n > 1) plane lens can not exceed 5(n -1) for lighter lenses or 5n for more massive lens. This mathematical thesis covers gravitational lensing and their properties that distort light rays coming towards us from distant celestial bodies. In addition of gravitational lensing, its properties and the proof of the maximum number of distorted images, a bigger part of this work even cover two very interesting mathematical tools - the so-called Schwarz function and Bezout theorem..

Extrem-/äventyrssport innanför gymnasieskolans väggar

Syftet med vår undersökning var att undersöka om extrem-/äventyrssport hade en plats i kursen idrott och hälsa A. Vi valde att skicka ut förfrågningar till 20 skolor i Malmö och grannkommunerna, av dessa fick vi svar från tio och endast fyra ville delta i undersökningen. Detta gjorde att vår undersökning omfattar fyra intervjuer med utbildade idrottslärare på fyra olika gymnasieskolor i sydvästra Skåne. I vårt resultat kom vi fram till att tre av lärarna hade extrem-/äventyrssport vid ca fem lektionstillfällen per termin, och en hade inga lektioner alls med denna typ av aktivitet. Det var många faktorer som spelade in när lärarna beskrev varför de inte hade så många lektionstillfällen med anknytning till extrem-/äventyrssport bland annat tid, resurser, skaderisk, engagemang och förutsättningar i närmiljön. Alla lärare vi intervjuade hade en positiv inställning till extrem-/äventyrssport i skolundervisningen och skulle gärna vilja få in fler lektioner med denna form av aktivitet, eftersom det hjälper att stärka elevers självkänsla, ger en allsidig träning och är ett bra verktyg för teambildning. Tre av dem såg det som väldigt viktigt att idrottsundervisningen i skolan följde med i utvecklingen, anammade de nya aktiviteter som ungdomar sysslar med utanför skolan och att extrem-/äventyrssport hade blivit ett stort fenomen i samhället.

Inverkan av flisig krossballast på betong

Concrete is one of the world?s most common construction materials and is composed of 70-80 % stone material. Today crushed stone is used as aggregate in concrete in order to replace natural aggregates due to strong environmental reasons. Stone crushing yields flaky material and in this thesis studies are made on the flaky particle shape and how it influence properties of concrete such as workability, rheology and strength. The concrete recipes used in this thesis have fixed values, the only variable is the flakiness of the crushed stone.

Flaskhalshantering genom materialstyrning : En fallstudie på LB-Hus

Title: Bottleneck management through materials administration Course:  4FE05EAuthors:  Mikael Karlsson and Johannes Mueller  Examiner: Helena ForslundKey words:  Bottleneck management, material management, process description, timber, proceduresPurpose:   The objective of this study is divided into three parts, all three parts of the purpose aim for the same goal. Namely, to improve the material management so that this enables the bottleneck in the planing mill to keep a continuous  flow, and thereby minimizing the risk for production stops at LB-Hus.  Part.  1:  Identify  and  analyze the material management  connected to  the planing mill  in order to identify problem areas.Part.2:  Identify  improvement potential  in the material management connected to the planing mill.  Part.3: Suggest improvements in the material management connected to the planing mill. Theoretical framework: Process mapping, inventory accounting, balance safety, inventory availability / service levels, safety stock and reorder point, forecasting and routine descriptions.Empirical foundation:  Interviews carried out at LB-House,  illustrated with the help of process maps and a description of each process.  Conclusions:  To work with  the  suggestions  given  and  to  follow  clear procedures  in  all  processes would  result in  a more  efficient  inventory management,  it would also present  a  solution  to  the problem regarding the planing mill being a bottle neck.Suggestions for further research: Review and map the information flow from demand to production start.

Sociala medier i Kina : En studie om användningen av sociala medier i en diktatur

The current research examined whether motives, traditional mass media consumption and individual differences (social activity and political interest) predicted the use of social media among a group of university students in China. In coherence with Uses and Gratifications assumptions the study found that the factors differentially predicted the extent of media use. Information seeking, social interaction and affinity were the main reasons for using social media. There was a negative correlation between television viewing and use of social media, in addition to a negative correlation between information seeking and use of the media. Results further suggest that social media are used to enhance social capital, since student?s being socially active offline, tend to use the media to a greater extent than those less active..

Dagdrömmar

Dagdrömmar är en tapetkollektion bestående av tre fondtapeter som kombinerar det moderna, massproducerade digitaltrycket med traditionell, unik broderiteknik. Genom att tillföra handbroderi och dess struktur och textila känsla till ett digitaltryckt tapetmaterial skapas en kollektion som befinner sig i gränslandet mellan design och konst, lyx och budget samt dröm och verklighet.Daydreams is a wallpaper collection consisting of three images that combines the modern, mass-produced digital printing techniques with traditional, unique needlework. By applying embroidery ? with its structure and fabric texture ? to a digitally printed wallpaper material, a collection is created that lingers on the borders between art and design, luxury and modesty as well as dream and reality..

Kommunal avfallsplanering i storstaden San Salvador, El Salvador

This paper deals with the use of Internet at Swedish public libraries. The author asks whether public libraries should or should not limit access to information available on the Internet. Starting from the American discussion, concerning Internet at public libraries, the author shows the Swedish attitudes. The paper demonstrates that many Swedish public libraries have adopted rules forbidding retrieval of certain kinds of information, such as hard-core pornography and racist propaganda. The persons in charge of such actions claim that public libraries should provide high-quality educational literature and should not spread mass-produced, provocative information.

Enumerating Atlantic salmon smolt production in River Vindelälven based on habitat availability and parr densities : consequences of using different density estimation methods

Habitat mapping was conducted in the main stem of River Vindelälven in the autumn of 2009 along the salmon distribution area. The aim was to estimate the quantity of potential reproduction areas, including spawning and juvenile rearing habitats. The mapping included 61 km of various stream sections along the river length of 269 km. The total area of stream habitats was estimated to 647 ha of which 396 ha (61%) were considered as either potential or optimal juvenile nursery habitats. The area of these two habitat classes were used to estimate the smolt production in the river by using electro fishing densities of juveniles (0+ per 100 m2).

FÖRBÄTTRAD MONTERING OCH DESIGNAV BAGAGELUCKA

This thesis includes a mechanical engineering design work performed incollaboration between ÅF and Halmstad University. The work is done by FredyOlsson?s methods of Principle- and Primary Construction and David Ullman?stheories of Design for Assembly.The group was commissioned by ÅF to produce a concept to narrow down theassembly time of today?s luggage doors by reducing the numbers of adjustmentoptions. They also wanted it to be easier to mount the assembly by making itpossible to adjust the door in a closed position. Today luggage door takes, with its10 adjustment possibilities, around 4 hours each to assemble and ÅF wanted anassembly time around 10 minutes per door.Initially a preliminary study was made where the group began reviewing today'sconstruction and mounting of rails and doors on buses.

Utvärdering av öppna dikens status och funktion : en förstudie i Västmanlands län

Evaluations of open Ditch status and function, with an assessment of suitability of a conversion to a two stage ditch as a low maintenance alternative. To illustrate Swedish drainage problems this work focused on two agricultural drainage associations assessed in detail with a new method called MADRAS (Minnesota Agricultural Ditch Reach Assessment for Stability). With the assessment of the MADRAS method estimates were made to conclude the ditches operating problems. This was made through measurements of sediment depths, mass bank failures etc. in order to quantify ditch problems and propose practical actions for improved ditch stability and water quality. The MADRAS surveys were conducted in two main ditches that drains 2900 hectares of land on the northern shores of Mälaren. In the study measurements of the ditch cross-sections were also conducted to compare actual profiles with the original map profiles. The evaluation showed that parts of the studied ditch sections were operatively poor; main reason was mass bank failure, undercut channel banks, sediment aggregations and narrowed ditches. The profile survey shows that a majority of the profiles 80 % has sediment accumulations there remains only 64 % of the original profile from the map.

All-In: En fallstudie om Betssons spelbutik och dess påverkan på den svenska spelmarknaden.

The company Betsson opened its first physical gambling shop in Sweden in May 2008, thereby defying the Swedish government?s legal gambling monopoly. The legal case that has resulted due to the violation of the Swedish gambling law has attracted immense attention from mass media, thus generating vast amounts of publicity for the company. This paper aims to evaluate and describe the company?s decision to open the store, as well as to examine the relationship between market driving practices and market driven practices.
