CAMPUS BTH - ett gestaltningsförslag och en studie av begreppet campus

This text answers the questions how do we define what a campus is, how the concept of the campus came to exist and how it is used today, and how the Blekinge Institute of Technology (BTH) campus can be designed according to site conditions and the conclusions drawn from case studies at Chalmers University of Technology and Karlstad University. The purpose of the case studies is to gain insight into their campuses advantages and disadvantages. This finally results in an interpretation of how the Blekinge Institute of Technology campus can be planned. A campus is the area of land on which a college or university and its surrounding buildings resides on. Campus as a concept meant a field at first, it later evolved at American universities due to their design of college campuses.

Produktionsflödesanalys - CA-Verken i Sävsjö

Examensarbete utfördes på CA-Verken i Sävsjö som bl.a. tillverkar hydraulcylindrar. De senaste två år har CA-Verken haft en kraftig ökning av omsättningen och det som står i vägen för fortsatt expansion är produktionen som har begränsad kapacitet.Målet med detta arbete är att studera CA-Verkens produktionsflöde för att kunna identifiera flaskhalsen/flaskhalsarna och därefter ge förslag på lösningar och förbättringar. Den teorin som har använts som grund till arbetet är Theory of Constraints (TOC). Intervjuer, företagets affärssystem och observationer har använts vid datainsamling.

Motivation i praktiken - En fallstudie om vad som skapar ho g motivation hos erfarna IT-konsulter

The purpose of this study is to examine what creates motivation in the workplace of a small company with a high employee satisfaction index. The case study consists of qualitative interviews that help explain what the most important motivational factors are for the experienced IT consultants in a company that was founded by a circle of friends. The study concludes that the unique and equal pay model implicates an economic risk to the individual consultant but results in liberties, synergies and benefits. These appeal more than either self-employment or work at a larger IT consultancy that several consultants have backgrounds in. An expansion is ongoing since two years back, which threatened the culture but implicated opportunities for the individual consultants.

Portrycksvariationer i lera - Simulering av portrycksvariationer i leror underlagrade av friktionsmaterial

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

"Din jävla hora, du ska dö!" : En studie i hur näthatet påverkar kvinnliga journalister

With the expansion of the internet, the conditions for the online journalists have changed. Feedback is faster and more blatant than offline. The online abilities of anonymity and dispersion attracts people to both use and misuse. During 2013, the online expressions of hate towards women has been brought to attention in the media more than ever before. Nevertheless, the phenomenon is far from new.Our qualitative research including interviews intends to find out how the afflicted women journalists are affected in their exercise of their profession.

Bonusar och finanskrisen : kan ett bonusstopp minska risken för finansiella kriser?

Denna litteraturstudie avser reda ut den eventuella kopplingen mellan bonus och dagens finanskris samt undersöka om ett bonusstopp för bankanställda kan minska risken för en framtida finansiell kris. Uppsatsen inleds med en förklaring av bankväsendets särart och vikten av ett statligt skyddsnät. Senare avhandlas relevant bonusteori och moral hazard, därefter en redogörelse för bonusens betydelse i finanskrisen. Vidare utreds bonusprogrammens inverkan i svenska bankers expansion i Baltikum. Vi har kommit fram till att belöningsstrukturen inom finansbranschen har varit felaktigt utformad då dessa belönat kortsiktiga vinster på riskfyllda affärer.

Biobränsleanvändning och Flameless oxidation i degelugnar för glassmältning

Idag värms glasugnar upp med antingen gasol eller olja, detta projekt vill visa på möjligheten att istället använda gas från biobränsleförgasning som förbränns utan synliga flammor. Detta skulle miljömässigt ge fördelarna att biobränslen inte bidrar till växthuseffekten och ge förutsättningar för att minska kväveoxidutsläppen genom bättre teknik än dagens.För att visa att det är möjligt att både behålla produktionen och reducera kväveoxiderna med förgasningsgas konstruerades en modell av ugnen och strömningsbilden studerades i vattenmodell. För att undersöka värmeöverföringen i ugnen behöver en eller flera kalorimetrar konstrueras för att kunna användas vid varma försök. Dimensionsberäkningar gjordes som visade att detta är möjligt med vissa typer av kalorimetrar..

Förstudie för kvalitetssäkringav glidande förband vid Hissmoforsvattenkraftsstation : -Specifikt för aggregat G6 och G7

Jämtkraft AB which is a power production company in Sweden has bought two newhydro power units to their station in Hissmofors. The two new generators are using aconcept with sliding stator feet to handle the thermal expansion.The concept with sliding stator feet on hydro electric generators has not beenworking satisfactory on many hydro power stations in Sweden and has caused a lot ofcosts due to long downtimes.The new station in Hissmofors is very important for Jämtkraft AB, and therefore theywant to know how to make sure that the sliding stator feet are working as theyshould. According to theories and a simplified model of the generator the stator feetdisplacement should be around 1 -1,6 mm.The generators are delivered with a surveillance system that will measure thedisplacement of the sliding stator feet. The signal from the system isn?t accessible forJämtkraft AB but it will alarm when the sliding stator feet are malfunctioning.To secure the function of the sliding feet a logger for the surveillance system or adifferent measurement system must be used; if both systems are used Jämtkraft cansecure the function of the surveillance system..

AbstractThis report intends through a case study to investigate if lightweight concrete isappropriate as main material in the outer wall of a seven storey residential building.A technical design is carried out in accordance with the definitions and requirementsfor passive houses, given by FEBY?s1 ?Demand specification for passive houses?.A literature review is also carried out for a comparison between regular bolt wall andlight weight concrete wall, with a focus on the safety of moisture.The lightweight concrete block used in the report is as a celblock produced by thecompany H+H Sweden AB.The methods used have resulted in compliance with requirements andrecommendations from authorities. Calculations of energy, noise and moisture riskassessment has been carried out.The work has resulted in the conclusion that the lightweight concrete itself is notable to isolate in the extent necessary to obtain chosen U-value of 0,1 W/m2 ° C,without getting to thick. Therefore additional insulation is needed. There are fewrelevant reference objects built with only light weight concrete.

Seniorer och internet : En studie om hur PROs medlemmar använder sig av internet

Since the Internet was introduced, it has taken over faster than anyone was ever expected it to do. It has taken over how we, humans, today live our life and is expected to accomplish our errands, such as paying our bills, ordering clothes and looking up information about travelling.With that said it is important to remember and have in thought that not everyone has the knowledge and skills to use the Internet, this because of the extreme development that the Internet brings.As mentioned above there is one group of people that has been called the ?forgotten group? when it comes to the expansion of Internet, and those are the seniors. Most of the seniors today have difficulties using the Internet due to either lack of knowledge or due to the size of the text on the websites, as well as the different color combinations. Since the seniors today have special needs on how to easily use a website, they are forgotten since most websites aren?t developed for seniors.However, sometimes appearances are deceiving and that is what this study has shown us.By questionnaire and interview study, the result of this study has showed us that the majority of the informants do use Internet, but they have special needs when it comes to the design on a website, and that includes color combinations, sizes of the text as well as on how to navigate from one page to another..
