Standardisering av processer och aktiviteter inom kontrollanläggningar och elmontage

I detta examensarbete har en undersökning utförts på konsultföretaget ÅF, och deras arbetssätt inom dokumentation och kontrollanläggningar för att utreda om det fanns effektiviseringspotentialer. Undersökningen har i största del innefattat intervjuer med verksamma konsulter inom kontrollanläggningar och elmontage på transformatorstationer. Konsulterna arbetade som konstruktörer och tog fram ritningar främst till kontrollutrustningar. Resultatet från intervjuerna analyserades för att sedan dra slutsatser om effektiviseringsmöjligheter inom verksamheten. Olika kontor i verksamheten undersöktes och arbetssättet varierade på de olika kontoren.

IKT för elever med ADHD : Nytta eller nöje?

The aim with this study was to see how a few teachers with experience of young students with ADHD looks upon the need of special support through ICT and from which perspective of special needs education the support is formed.I related the informants? answers about their views on special needs support based on a relational and categorical perspective and came to the conclusion that all of the informants uses a bit of both depending on each individual students needs. Therefor I could see that the dilemma perspective is current in schools today. The most important need for the students with ADHD in general is, according to the informants, structure and routine.The result from this study also shows that general knowledge about ICT is lacking and needs to increase. This could in most cases be explained by the schools economic resources as that partly prevent purchase of new and more equipment but also forces the school to keep larger groups of students in each class.

Inköpsoptimering och kostnadsreducering

This thesis has been carried out at Diac Metal AB at Torsvik outside of Jönköping. The company produces parts for, amongst others, office furniture and store equipment. The essay will be concentrated on one detail which is included in many of their products.Today the company uses an ordering quantity based on experience which is rarely updated. Furthermore the operations are performed in both the company?s own engineering workshop but also an external workshop.The purpose with the report has been to check whether an updating of today?s batch shaping and ordering system can mean simpler storage control and possibly cost reduction.

Sönderdelning av plogtilta med skärknivar :

During the last couple of years it has been more important to reduce the driving on the field to prepair the soil after ploughing. The machine costs are high so it is necessary to be effective. To reach a pleasant soilbed directly after ploughing is sometimes possible on easier soils but heavier clay soils always need more tillages. There is a lot of equipment mounted on the ploughs on the market, for example Furrow Cracker and Furrow presses, which makes a pleasant soilbed on easier soils. The last year Överum and Kverneland have presented knives which are mounted on the wing or moulboard.

Betongarbeten under vintertid : Fokusering på platsgjuten betong

This report is on concrete work during the winter and is implemented on Peab?s behalf. The assignment was to describe the differences between a summer- and a winter casting. While it shows the complications that exists, it also show what aids are available, both electronic via computer and physical aids.The information that I have developed is originally from theory in books, information on the internet as well as practical experience from knowledgeable people that works in construction output. Other theories are those I have learned throughout the education to become a construction engineer, including all oral sources over the years.The results I have come up with, I hope will be able to help future construction projects in the planning phase of a winter casting.

Utveckling av 2D bildanalysmetodik för mätning av  järnmalmsråkulors storlek och form

År 2009 antog IMO en ny resolution som innebär att ett nytt instrument gradvis kommer införas som obligatorisk standardutrustning på fartygsbryggan. Detta system förkortas BNWAS vilket står för Bridge Navigational Watch Alarm System och är kortfattat ett dödmansalarm som syftar till att varna vid otillräcklig aktivitet på bryggan. Detta system har funnits en tid men blir nu obligatoriskt ombord. Detta påverkar arbetssituationen och arbetsmiljön för vakthavande styrmän. Denna studie syftar till att undersöka vad styrmän som arbetar med systemet har för uppfattning och åsikter om systemet.

Tidsåtgång i system med självgående/självlastande fullfoderblandare :

In this study I have compared two systems of handling TMR, self-propelled/ self loading mixers and conventional towed mixers, what has been investigated is the time for filling, mixing and feeding TMR as well as maintenance and fuel consumption. The background of this study is the structural rationalization within the Swedish milk production that has put focus on efficiency and reducing of costs. Forage and labour are the two biggest costs in milk production today. The study has been performed by visiting three farms and with a stopwatch measured the times for filling, mixing and feeding TMR. At the time for the visits, the users have been interviewed regarding maintenance and fuel consumption. They have also had an opportunity to give comments of how they experience the mixers. The result of the study after processing is that the average stock in the study can save 74000 SEK a year by reducing time for filling, mixing and feeding TMR to cows with a self propelled/ self loading mixer . The conclusion I can make of this study is that it?s not the size of the stock that decides whether it?s interesting to invest in a self propelled/ self loading mixer, but the presumptions on the farms, for instance forage logistics and mechanical equipment..

PRAKTISK BESTÄMNING AV KLÄMKRAFT OCH FRIKTION I SKRUVFÖRBAND

This report reflects an examination work performed for Getrag All Wheel Drive AB during the spring of 2005. Among the companies range of products there exists some concern regarding the amount of clamping force and friction on bolted joints caused by the assembly torque.The aim of this project has been to determine if there is a simple way in which to identify and then practically apply testing methods for clamping force and friction through utilization of existing testing equipment.Three separate methods of clamping force and friction determination have been tested in rear drive unit, RDU, at a 30 Nm assembly torque. A fourth and final method, screw elongation with ultrasound, has been used as reference. The methods are:?Torque-Tension test.?Screw elongation with micrometer.?Joint stiffness test.?Screw elongation with ultra sound for reference.The results from tests can be viewed in table below.MethodTorque-TensionMicrometerCs=318 kN/mm Assembled with torque wrenchMicrometerCs=318 kN/mm Assembled on lineUltra-soundCS=311 kN/mm Ultra- soundCS=318 kN/mm Joint stiffnessTheoreticalClamping force-21,8 kN17,6 kN17,3 kN17,6 kN17,1 kN17,3 kNFriction-0,110,1470,1530,1470,1520,149.

Undersökning av exponeringsindex för bildplattesystem inför optimeringsarbete

The county hospital of Dalarna has for the last couple of years carried through a process of digitalization. The result is that within the county it exists image plate systems from two different manufacturers. In an attempt to create a tool for dose optimization and dose surveillance the county of Dalarna would like to investigate if the exposure index from Agfa and Fuji is suitable as a dose indicator. An investigation of the exposure index, S, from Fuji has already been done. This thesis has been continuing the investigation by evaluating the stability of the exposure index, lgM, from Agfa.

Orsak till sjuksköterskans stress och hur den påverkar omvårdnadsarbetet : En litteraturöversikt

Nurses in health care have a responsible and sometimes stressful job. Nowadays there?s a high pace in health care where many decisions have to be made during time pressure, a lot of information has to be transferred between health care units and sometimes complicated equipment are used. Cases of mistakes are reported more than ever to the national committee responsible for health care. Many of the mistakes, where the nurses are involved are due to the nurses? stress.The aim of this study was to gather information to describe causes of stress in nursing care and the nurses? experience of stress influence on health care.The method that was chosen for this study was a literature review where scientific, critically reviewed articles were analyzed.  The analysis resulted in two main themes.

Skattereduktion : Bör arbetskostnaden regleras i lag

The Income Tax Act is enacted what criteria must be met to obtain a tax reduction of household work. Household work is the common term for ROT- and RUT-works. The purpose of the tax reduction is to increase job opportunities and to discourage that undocumented work performs.It is only for the labor cost as tax reduction is given for. The concept of labor cost is defined in law as it is not comprised of cost of materials, equipment or travel. The preliminary work provides no closer explanation what the labor cost includes.

Nedbrytning av vägar: Jämförelse mellan axlar med singel- respektive tvillingmontage

When designing roads it?s important to knowwhat loads will bedriven on it. The axles on heavy vehicles can either have super single tires ordual tires which, according to studies, damage the roads differently. The SwedishTransport Administration is developing an understanding for the character ofthese different kinds of axle and tire types on the loads induced on Swedishroads. In this thesis a field study was conducted to determine the distributionbetween axles with super single tires and axles with dual tires on heavy vehicles.A highway, a country road and a national road were investigated during thestudy.

Effektivare hantering av foderspannmål : en fallstudie

The purpose with this work was to investigate some alternatives for an effective handling with grain, to find the most economic alternative. It is not common that moisture content is below 14% when harvesting grain in Sweden. To store the grain safe it has to be preserved in some way. I have described some of the most common systems for preserving grain in this paper. I have used the systems as a basis when I made calculations in handling the grain for a company. I have chosen a company placed in south of Sweden. The productions are crop farming and pork.

Användandet av mobila enheter med appsystem och appars fackmannamässiga potential inom byggbranshen

Mobile devices such as tablets and smartphones are quite common in this day. The author of this thesis wanted to know how common these mobile devices are in the building industry and how they are used and what potential an app could have. The author thus conducted an investigation on this matter, mainly in the form of interviews.Answers given by the interviews were then used as a basis to survey the usage of mobile devices and the usage of different kinds of apps. An investigation of different apps with the potential to be used by professionals in the building industry has been carried through. Apps which manage such things as scanning documents, measuring distances and handle communication.

Varför CSR?: En fallstudie på SAS om orsaker till företagets arbete med Corporate Social Responsibility

The term CSR (Corporate Social Responsibility) is frequently discussed today. Many large companies work actively with CSR related questions. However, few empirical studies exist on what this work entails and why it is undertaken. Instead, most of the academic research focuses on what the term itself should mean. To bridge this gap this study centers on the employees? perceptions of CSR.
