Ekonomistyrning i interorganisatoriska relationer

Background: Inter-organisational ways of working have become more and more common during the last decades. In order to attain efficiency and productivity, such inter-organisational relationships need to be governed and controlled. However, studies have shown that inadequate control is one of the main reasons for why inter-organisational relationships fail. One of the means that can be used for governing and controlling a business is management control. The use of management control in inter-organisational contexts is a quite unexplored area of research at the present time, which might seem somewhat surprising considering the fact that inadequate control is a common explanation for why inter-organisational relationships fail.

Broms- och styrsystem för möbeljalusier

This report is the result of a master thesis at the Department of Mechanical Engineering, Division of Industrial and Economical Development, at Linköping University of Technology. The project was carried out on behalf of Fanerami AB, Mjölby and includes 20 weeks of full time schedule work.Cabinets with vertical mounted roller shutters all share the same problem, namely weight balancing. A roller shutter has an equilibrium area where the sum of the different forces acting on the shutter equals zero. As the shutter leaves that area it will pick up speed as it falls towards the bottom. When the shutter hits the bottom of the cabinet there is a potential risk of getting fingers caught and in this project a solution to prevent this from happening was to be presented.In this project, three concepts have been generated with the following different purposes:?In concept 1 the risk of getting any fingers caught when the shutter closes was to be eliminated in an efficient and inexpensive way.?In concept 2 the roller shutter had to be balanced at all time providing the possibility to keep the cabinet open in any position.?The last and most challenging task was to create a remote controlled TV cabinet.

Tillförlitlighet hos information som hanteras av flera användare och genom flera system

When investigating mechanical problems it is often more convenient to deal with scalars rather than vectors. In this project methods stemming from the field of analytical mechanics, which lets one derive the equations of motion using scalar quantities instead of vectors, have been used. Two mechanical problems were investigated, a double pendulum with a spring and particles orbit in a sphere. The equations of motion of the two systems were derived with the assistance of computer algebra, using Maple and the external package Sophia. The systems were investigated with regard to periodicity and conserved quantities..

This project was led on behalf of Bombardier Transportation in Västerås, Sweden, incollaboration with KTH Stockholm and EPFL Lausanne. This project is connected to thedevelopment of a new and simplified tilt system for rail vehicles.Growing competition from other means of transportation has forced railway companiesthroughout the world to search for increased performances.Travelling time is the mostobvious performance indicator that may be improved by introducing high-speed trains.They require very large curve radii and long transitions curves not to impairridecomfort, another performance indicator. Building new tracks adapted to high speedtrains is very costly and can only be justified where the passenger base is large.Trains with the capability to tilt the carbodies inwards the curve is a more cost efficientalternative. The tilt inwards reduces thelateral force felt by the passengers allowing thetrain to pass curves at enhanced speed with maintained ride comfort but increases thefrequency ofmotion sickness.The benefits of tilting trains are improved speed capability in curves and enhancedpassengers comfort, but at higher buying and maintenance cost. As the conventionaltrains increase their speed in curves, the performance advantage of tilting trains isreduced while their prize is still kept significantly higher and constant.

Motiv och motivation till motion

Ohälsan ökar i västvärlden som en följd av bland annat försämrade kostvanor och alltför lite fysisk aktivitet. För att öka aktivitetsgraden hos den vuxna befolkningen i Sverige erbjuds många via arbets¬givaren möjlighet till friskvård på betald arbetstid. Syftet med denna studie var att undersöka olika aspekter av motivation och inställ¬ning till motion hos individer som nyttjar respektive inte utnyttjar friskvårdsförmånen. Data samlades in genom semistruktu¬rerade intervjuer med tio personer vilka sedan analyserades enligt teoristyrd tematisk analys. Deltagarna besvarade även ett standardiserat mät¬instrument (Sport Motivation Scale).

Omvårdnad av självmordsnära patienter inom psykiatrin - En kvalitativ intervjuundersökning utifrån ett sjuksköterskeperspektiv

Suicide and attempted suicide frequently occur in society today and represent a major public health problem. In inpatient psychiatric care the nurse have a central role when caring for suicidal patients. Few systematic studies exists that address the nurse?s practical work with these patients. The purpose of this study was therefore to describe the nursing care of suicidal patients as it was perceived by registered clinical expert nurses.

Intern kontroll : Inom mindre grossistföretag

Accounting is a well discussed topic, and an important tool that allows stakeholders and others to interact with the companies. To gain credible reports, the companies require maintenance, activities and monitoring. Wholesalers account for approximately 20% of Sweden's net and is increasing at a steady pace. Few studies on wholesalers are acquired and the internal control has shown to be important for the preparation of the financial statements.Therefore the study will be focusing on the smaller wholesaler?s internal control, all the way to the financial statements.

När gränsen för styrning suddas ut - En fallstudie av hur ett företags styrning påverkar dess kundrelationer

As collaboration between companies move beyond the single transaction into more long-term relationships the consequences of a company's control system become more complex. The aim of this paper is to provide an understanding of how intra- and inter-organizational control and work practices interact through examining how a company's intra-organizational control influences its customer relationships. The empirical research is performed through a qualitative case study where interviews have been conducted with management and sales staff within the case company as well as with one of the customers. The empirical findings have been analyzed using frameworks and theories regarding management control and customer relationships. The study reveals that the intra-organizational control of the case company affects its relationships with customers in a number of ways.

Automatisering av spraytorkningsprocess

ABB Surge Arrestors in Ludvika have for a long time had a problem to keep the moisture at a steady state in the production of their ZnO-powder, that is used to produce varistors.Some black-box models of the spray drying process have been designed and evaluated to find a solution for the problem. After evaluating the collected data it has been found that variations in the supply voltage causes control difficulties for the operator. A cascade control system was designed, consisting of three PI control loops designed with lambda tuning. The disturbance in the supply voltagewas used as a feed forward in the control system.At the end of the project the control system was installed, and tests were made to verify the functionality of the regulator. It was shown that most of the variations in the moisture of the powder could be eliminated using small resources, through purchase of a process controller and four power meters.

I resultatet framkom det att personer med diabetes typ 1 upplevde svårigheter såsom psykiska påfrestningar, påverkan på det sociala livet, planering och ökat kontrollbehov. Fördelar som framkom var en ökad självkännedom, känsla av gemenskap och att få en sund livsstil.

Styrreglage för hållbarhetsstyrning - En fallstudie av hur företags interna styrning aktiverar Levers of Control för att uppfylla hållbarhetskrav

The connection between management control systems for controlling sustainability and a firm's motivation for engaging in sustainability is not completely understood (Arjaliès & Mundy, 2013). The aim of this thesis is to develop a more profound understanding for management control in achieving sustainable companies. To do this, we raise the question: How and to what extent do companies use management control systems to achieve sustainability compliance Simons's Levers of Control (1995) are applied to this question in order to get a consistent and thorough insight of management control systems. Hence, a case study of ABB:s work to achieve material compliance in accordance with EU-regulation was conducted. The findings of the case study reveal that ABB uses the regulations as explicit goals and implement them in sustainability procedures.

Live slow motion: from idea to product

Vi ville undersöka om det var möjligt att på en begränsad budget bygga och programmera en Live Slow Motion-maskin för att generera repriser under en TV-sändning. Utan tillgång till dyrare specialtillverkad hårdvara skulle allt skötas i mjukvara på i grunden en vanlig konsument-PC. Vi ville så långt som möjligt att vår maskin skulle efterlikna de etablerade produkter som används i TV-branchen då vår förhoppning var att maskinen skulle kunna utnyttjas av TV-studenter efter färdigställandet. Vi ville dock inte begränsa oss för mycket, utan vi skulle försöka förbättra de saker vi ansåg behövde förändras..

Triac Driver Platform

In the electronic industrials, power control of AC motors is commonly used. For example power control of a washing machine motor, a vacuum cleaner motor or a coffee machine motor. The company Rejlers Ingenjörer AB has many projects where power control of AC motors is included. A prototype card for this task can save time and money for the company in the future and this is the reason for this thesis.The motors are power controlled by a TRIAC and control of the trigging pulses to the TRIAC. This card is modularly built and can easily be adapted for future projects where the power control of AC motors are included.The prototype card can be used as a subsystem in a larger electronics projects or as it is in lab environment for testing and evaluating new motors..
