When constructing a road the risk of emission of substances from the used materials to the surrounding environment has to be evaluated. The aim of this study is to present a proposal for how to evaluate the risk of contamination as a result of emission from the materials in a road construction. The study is based on literature studies, an inventory and a questionnaire that examines how experts in governmental agencies, industries and universities evaluate the risk of contamination. The inventory indicates that guidelines for evaluating the risk of emission from secondary materials in a road construction do not exist. The conclusions from the questionnaire are: that there is no common way to evaluate the risk of contamination as a result of emission from materials in the road construction, there is no uniform interpretation of the terms "minor" and "significant" risk of contamination and that the evaluation is subjective.

This study investigates whether the permanent measurement bias (PMB) has changed over time for Swedish companies listed on the Stockholm Stock exchange at least one year during 1996-2000 or 2005-2010. By using the Residual Income Valuation-model the markets' implicit value on PMB is generated through reversed engineering, as values for all variables except PMB are entered such as the market perceived them at the specific valuation date each year. This implicit value is classified into industries and then sorted by their median. Statistical tests are performed to see if there is a difference between the industry median and the accounting-based values on PMB. The difference from period one to period two is also statistically tested for.The study finds that the implicit values on PMB have changed somewhat between the periods; however the fluctuations are not statistically significant.

The aim of this master thesis is to examine the opinions of the students of Linköping University regarding the role of the university library in their learning process. The study addresses the student?s expectations and satisfaction regarding the library services. The questions we seek to answer are: What are the students? conceptions of Linköping University Library as a part of their learning process? What expectations do the students have regarding Linköping University Library? Does the library fulfil the students? expectations? In what way has the library?s pedagogical ambition reached the students? What are the students? opinions about the user education? The study is based on a web survey complemented with interviews.

This thesis has been performed as a part of the Bachelor degree in Industrial Engineering and Management at the School of Engineering in Jönköping. The thesis is written on behalf of Pallco AB, which is an engineering company that performs subcontracting, surface treatment, and assembly of components, mainly in steel and aluminium. The thesis focuses on identifying and analyzing the customer order fulfillment process of three customers at Pallco AB.The main objective of the thesis is to distinguish time differences in the company?s administrative work for each of the three customers. Furthermore, Lean thinking is following as a thread through the whole thesis.

Urban operations is one of the most difficult challenges a modern army can be tasked with. These challenges have been studied in history and present with various perspectives, but rarely from a combat engineering point of view. The purpose of this thesis has been to study the urban capabilities of a Swedish combat engineer company by examining if it can perform similar combat engineering fieldwork that supported the basic capabilities mobility, defence and effect in Operation AL FAJR, Fallujah Iraq 2004. These are the capabilities a Swedish engineer company are primarily designed to support in urban operations.For example, the study of Operation AL FAJR has shown that fieldwork supported mobility with breaching minefields, obstacles, walls and doors. Defence by creating defensive positions and obstacles.

The main purpose of this study is to investigate and understand how technology students handle information especially when they are working with their Masters thesis. A further purpose is to examine how technology students use library resources of the Linköping University. The research method used is grounded theory, where description of the method is an integral part of the study. Twelve qualitative interviews were made with newly qualified graduates from the engineering programs of Linköping Institute of Technology. The respondents were divided into two groups, A and B, with six in each group.

Syftet med examensarbetet var att skapa ett kostnadseffektivt, vackert fackverk av limträ i en samtidig utvecklingsprocess med arkitekt, konstruktör och entreprenör. Metodiken har till stor del följt idéerna i concurrent engineering, en samtidig utvecklingsprocess där alla involverade gemensamt kommer fram med förslag och lösningar. I och med att arkitekt, konstruktör och entreprenör jobbar samtidigt utformas också hela konceptet inklusive detaljer och produktionsprocess i en och samma utvecklingsprocess. Till stöd för beslutsfattandet i designprocessen har axiomatisk design använts, vilket är en metodik som hanterar design i matematiska termer. De olika lösningar som evolverar från processen concurrent engineering har sedan optimerats med ett Matlab-program med avseende på lägsta materialkostnad.

This report is a bachelor thesis work within the field of Product Development and is also an assignment for Thule Sweden. The work has been performed by Niclas Tjäderborn and Christian Holm, students at the Mechanical Engineering Program with major in Product Development and Industrial Design at Jönköping School of Engineering during spring the semester of 2009.The thesis work concerned the development of a new wheel holder for bike carrier for Thule Sweden. The background to the project was that the initiator wanted a more user friendly wheel holder with better design than those available on the market. The wheel holder is able to be implemented on one or several of Thule?s current wheel holders.

This report describes the planning and the accomplishment of the final diploma workat the study program Mechanical Engineering, Department of Engineering Sciences, Uppsala University. Two students carried out the diploma work at GE HealthcareHusbyborg in Uppsala.The aim of the diploma work was to develop and improve existing processequipment for 11C-radiochemistry in PET. The process equipment was to be dividedinto smaller independent modules to make it more flexible. Part of the existingprocess equipment is an oven that is supposed to perform a specific chemicalreaction. One of the main goals was to study and improve this oven.The work could be divided into three main phases: 1.Present concepts for one module, and interface between different modules.

The aim for the project was to develop a risk analyse tool for measuring the fire safety level in Cultural Heritage buildings of Visby, Gotland. In 1995 Visby were taken into the Unesco:s World Heritage List with the explanation ?Visby is an outstanding example of a Northern European walled Hanseatic town which has in a unique way preserved its townscape and its extremely valuable buildings? One of the demands for the tool was that it should be easy to use and result into a ranking level in examined buildings. The user of the tool is recommended to be personnel in the fire department. To develop the tool a Multi Attribute Decision Making (MADM) method was used.

This paper discusses sound education within school subjects such as music, science, engineering, computer science, and Swedish to classes at the intermediate stage..

This bachelor thesis is about an ultrasonic sensor, implemented in a bubble chamber in Artis. The sensor consists of the piezoelectric sensor and an electronic control circuit. The control circuit consists of a programmable microprocessor, PIC18F2420 and a circuit, which sends the excitation signal to the piezoelectric sensor, and later receives the echo. This bachelor thesis consists also of a theoretical study, which examines different techniques of liquid level sensing in a chamber. The study discusses which factors are important in liquid level sensing and examine accepted methods.

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.
