En intuitiv & lättillgänglig flyktmask för gruvmiljö
I have always lived around mines and around people working with mines. They are a natural part of my life and, inevitably, a great interest of mine. When time came to make a decision for a degree project, focusing on the mine context felt as natural as breathing.In LKABs underground mines, safety in fire accidents is a great priority. Of outmost importance for the escape is to have a personal gas filter for filtration of smoke and/or gas. My design project resulted in a concept which is aimed at shortening the user journey from the start of the accident until the user has applied the personal safety solution and is ready to escape.Throughout the project I?ve been working with a context which is heavily regulated, and all problems are serious, important ones.
Blinkets påverkan - En studie om rörliga skyltar i butik och dess påverkan på försäljningen samt konsumenternas attityd, köpintention och beteende
Studies show that visual elements in store have a great impact on consumers. Of all the impressions that the brain receives the visual impressions count for 83 %. One of the visual elements that retailers can use in-store to influence consumers is signs. Today, there are a lot of studies on regular signs but this is very limited when it comes to motion displays. Motion displays are signs printed on electronic paper with animated messages.
Utvärdering av Windows 8-applikationer ur ett utvecklarperspektiv
With Microsoft's new operating system, Windows 8, a new type of applications were introduced, Windows Store Apps. These applications must meet certain requirements in order to be uploaded to Windows own store for apps. There are also guidelines to follow. The requirements and guidelines include appearance and functionality, such as a common search function in the applications to contribute to a more unified experience. How does these requirements and guidelines influence developers? Whether the development of the Windows Store Apps gets more difficult, or perhaps even simpler, is studied and evaluated in this report.
Utveckling av mobilapplikation
The company System Andersson is developing systems for controlling materials and production in industries. They want to add a new service, where parts of those systems are accessible through cell phones.In this paper we are investigating which technology are best suited for this kind of application. And then we describe how we are developing a prototype fort this application, based upon that technology. After investigating technologies such as Java ME, Microsoft Silverlight, and web applications we settled upon building the system as a web application, customized for a mobile environment.To build a web page which is readable by many different cell phones we use the markup-languages which are developed for cell phones. We put much effort in reading about the standards and recommendations for the mobile web, produced by the organizations W3C and OMA.
Pilotstudie för utformning av modell att uvärdera utrustning
Swedish Trotting association was formed in 1925. They are the ones who design the regulations concerning what is permissible and not permissible for the horse, driver and trainer, when they have a license at a Swedish racing track. The Veterinary department of Swedish Trotting association decides in consultation with representatives from veterinaries around the country what is allowed and not allowed, based proven experience, combined with the availability of scientific data and Veterinary Department's own assessment.
After stricter regulations for good animal welfare from the Swedish government, Swedish Trotting association is going to work out a workable model for how new equipment can be tested in the future to see how the equipment affects the horse. In the future, all equipment will be objectively tested before approved. The purpose of this work was to develop a well-functioning model for this.
The research-question for this work is:
Is this study design a well-functioning model of how the equipment should be tested in the future?
The equipment used for designing this model was bitless bridle with a bit.
Finansiell risk och lönsamhet i Svenska fastighetsbolag under 2008
Syfte: Studiens syfte är att analysera och undersöka om det finns något samband mellan den finansiella risken och lönsamheten. Det övergripande syftet är att se om valet av finansiell risk fungerar som finansieringsstrategi i verkligheten.Metod: Studien bygger på den deduktiva ansatsen där teorier kommer att testas och analyseras mot empiriska data tagna från årsredovisningar. Den kvantitativa metoden används då data från 305 stycken årsredovisningar ska användas för att finna om det finns samband och variation mellan finansiell risk och lönsamhet definierad som vinstmarginal, Rt och Re. Årsredovisningarna utgörs av sekundärdata som samlats in från databasen Retriever. De statistiska metoder som används är bland annat medelvärde, standardavvikelse, regressions- och korrelationsanalys, hypotesprövning och t-test.Resultat och slutsats: Såväl korrelation- och regressionsanalys som hypotesprövning och t-test visar att det finns samband mellan finansiell risk och lönsamhet definierad som Re.
Analys av energianvändningen i kvarteren Carolina och Jenny : en fallstudie
An energy study has been performed on two blocks in an area called Gävle Strand. The buildings are owned by a tenant-owner?s association called brf Carolina and were built by the company Skanska 2008. The builder as well as brf Carolina are pussled by the fact that electricity use is higher than expected while heating is less. Skanska is also very interested in finding out how much heat recovery from stale exhaust air through a geo-thermal heat pump is contributing to the general heating requirement and energy balance in four out of the ten buildings located on the properties.To find possible answers to the higher electricity use a literature survey on user behaviour was conducted.
Back to the roots. Utforskande studie av mina minnen från Dalarna
Jag har som examensarbete på master-nivå formgivit en sittmöbel med utgångspunkt från min uppväxt i Dalarna. Målet har varit att göra en filosofisk tolkning av mina minnen samt en hyllning till regionen, i synnerhet Borlänge där jag växt upp.Jag har under projektets gång gjort en resa både på ett mentalt och rent fysiskt plan tillbaka till den plats jag växt upp för att utforska mina minnen och därigenom skapa en plattform för mitt designarbete.För att nå mitt resultat har jag använt mig av designmetoder som ITK, intervjuer, skisser, studiebesök, materialtester, mockups samt modelleringsverktyget Rhino.Resultatet är en stol inspirerad av saker som bland annat Ornäs stugan och musikkulturen i Borlänge. Stolen består av en metallkonstruktion, trädetaljer vid fötterna samt armstöden och en sits i läder.For my thesis work on postgraduate level, I have designed a chair based on my upbringing in Dalarna. The goal has been to make a philosophical interpretation of my memories and a tribute to the region, particularly Borlänge where I grew up.During the project I have made a trip both on a mental and physical level back to the place where I grew up to discover my memories and thereby creating a platform for my design work.In order to achieve my result, I have used design methods such as ITK, interviews, sketches, field trips, materials testing, mockups and the modeling tool Rhino.The result is a chair inspired by things like Ornässtugan and the music culture in Borlänge. The chair consists of a metal construction, wooden feet and armrests and a seat made from leather..
W3C Geolocation API ur ett utvecklarperspektiv
The goal of this thesis is to investigate the W3C Geolocation API from a
developer?s perspective, focused on whether it makes development of
location-based applications more accessible to developers. This has been
investigated by looking at available ways to locate, possible uses, the
functionality offered, the necessary level of prior knowledge needed for a
developer and requirements on developer tools.
This has been achieved through studies in relevant areas, a thorough
introduction to W3C Geolocation API functionality, and by using the API to
develop two different location-based applications as a demonstration. Testing
of applications, on different platforms and in different environments, in
conjunction with investigation of the rest of the material has shown that W3C
Geolocation API in many ways actually makes development of location-based
applications more accessible for developers. The API also provides fully
adequate functionality and quality to meet the requirements for development of
both simple and very advanced location-based applications.
Målet med denna uppsats är att undersöka W3C Geolocation API ur ett
utvecklarperspektiv, fokuserat på om den gör utveckling av positionsbaserade
applikationer mer tillgänglig för utvecklare.
Guideline for testing electrostatic discharge on whole vehicle
Det finns två stationer på Boxholm Stål AB med produktionssågar. Den ena är en bandsåg och två fasmaskiner med hanteringsutrustning för transport mellan såg och fasar samt en automatisk buntmaskin. Fasarna på den stationen är utslitna och håller inte de toleranser som Boxholm Stål AB har på sina produkter. En önskan att kunna planfräsa ändarna har också tillkommit vilket utrustningen i dagsläget inte klarar av. Det innebär att fasarna ska bytas ut.
SOAPIF ? Ett ramverk för utveckling av tjänsteorienterade API:er
Denna studie syftade till att ta fram ett ramverk för utveckling av API:er för tjänsteorienteradearkitekturer. Studien tar sin utgångspunkt i forskningsprojektet e-Me (utvecklingenav en integrationsplattform för att underlätta studenters vardag) samt en benchmarking avde i nuläget mest använda API:erna på webben. Studien har fem faser: En litteraturstudie,en benchmarking, en kvalitativ genererande intervjustudie, en teoribildande fas (framtagningav ramverket), samt en kvalitativ validerande studie. Litteraturstudien tar upp sådanafenomen som utvecklingsmetoder, systemarkitekturer (bland annat SOA) samt metautveckling.Denna studie låg till grund för den första intervjustudien, som i sin tur låg tillgrund för benchmarkingen. Resultatet av dessa två studier bildade tillsammans en grundför ramverket SOAPIF (Service-Oriented Application Programming Interface Framework),som till en början innehöll fyra olika faser: Conceptualization, där man försökerbilda sig en uppfattning om vad API:et skall exponera; Definition, där man försöker definieraett kontrakt för API:et; Testing & Implementation som tar sin utgångspunkt i testerför att implementera API:et; samt Delivery, som är den fas där API:et skall levereras.
Ethanol for Scania's Future - A Scenario Based Analysis
Abstract Title: Ethanol for Scania?s future ? A scenario based analysis Authors: Anna Hansson and Julia Persson Tutors: Annette Cerne ? Department of Business Administration, Lund University Jonas Holmborn ? Head of Advanced Combustion, Engine Development, Scania Lennart Thörnqvist ? Department of Energy Sciences, Faculty of Engineering, Lund University Problem: Oil-based products are the dominating fuels in the transport sector but alternative fuels are currently challenging the world-wide dominance. The large number of alternative fuels that are under development at present makes the future fuel-market impossible to predict. Scania?s ethanol project is associated with a number of uncertainty factors that are beyond the company?s control.
KB-ryggstödet : Vidareutveckling av ett justerbart ryggstöd för rullstolar
This master thesis is commissioned by Permobil AB. The report describes thoroughly the developing process of an adjustable backrest for wheelchairs. The target group for the backrest are people that suffer from scoliosis or other spinal diseases. Because of insufficient pressure distribution usage of traditional backrests is not an option for them.The current solution has got a frame that is made by several adjustable links that is held in place by friction. Between the links velcro tapes are attached that is adjusts the depth.
E-handeln är det nya svarta ...så var noga med hur du stylar den.
Ever since Internet revolutionized the world, e-stores and e-commerce has grown into becoming a natural part of consumer's everyday life. Much thanks to it's facilitative and time saving characteristics. Online, consumers are provided with a huge assortment and the opportunity to shop any time they like. Yet, the absolute greatness of e-stores is the possibility to push prices below the physical store price, which seems to be most appreciated to a large extent by consumers worldwide. The fact that e-store sales in Sweden grew 14% last year verifies this.As more players step into the virtual world of e-commerce the competition gets tougher.
Förrotation till omrörare
The primary function of a mixer is to keep a fluid in constant motion. All mixing applicationsrequire varying degrees of small-scale turbulence and bulk flow. The performance of asubmersible mixer is measured by the thrust that it produces, while the strength of the bulkflow is dependent on the total amount of installed thrust.In a mixer, the fluid quickly flows past the propeller, and as a result, the current is mainlyaxial. The fluid will also obtain a rotating velocity, or a swirl, though this is significantly lessthan that of the propeller. During the process, the total amount of energy increases in the formof static pressure and kinetic energy.
