Mätning i nätstationer - nyttor och problem

The purpose of this study has been to investigate advantages and problems with distributionsystem metering in substations. This report is a study in cooperation with Göteborg Energi.The analyses in this report are made for GENAB, a subsidiary company of Göteborg Energi.To analyse advantages and problems in advance is interesting information for GENAB. Theresult of the report could be based upon whether installation of metering in distributionsubstations will be implemented and in that case which kind of measurement that is relevant.The most relevant and strategic place to implement measurement is at the distributionsubstations on the secondary side (400V), this is due to the placement of the currenttransformers. The measurements in this study involve current, voltage, power, power factor,temperature, energy and power quality.Measuring instruments that are relevant to implement are intended to measure current,voltage, power, power factor, energy and, possibly, power quality in the same measuring unit.It is desirable to have a measuring instrument that measures both energy and power qualitybut since it is most often a cost question, it can be established that energy meters have a lowercost.Metering in distribution substations gives a better illustration of the power network. Thisresults in many advantages for GENAB.

Dåligt samvete och tidspress : en studie om modernt föräldraskap

The purpose of this study was to examine the problematic and frustrating aspects of parenthood in the modern runaway world of today. In other words, we wanted to study how parents in Sweden experienced their life as parents in the beginning of the 21th century.We wanted to find answers to the following questions:What kind of problems do parents experience and how do they deal with these problems?What would parents consider to be typical for them as parents compared to how they remember their own parents?What do parents think about family politics?Do parents think they need parent education?If parents want parent education, why do they want it?To answer these questions we used qualitative interviews. With this method we got information from six parents and five professional parent educators who was kind enough to let us interview them. We also gathered information about the subject through literature and news articles.The result of the study can be divided into three parts.

En undersökning av arbetssätt vid designprocesser

The aim of this study is to explain the paradox of the memberstates willingness to surrender power of important issues such as asylum and refugee policy and therefore partly abandon its sovereignty. We also discuss the relation between internationalization, regionalization and globalization since these processes form the context in which our research problem is found. A case study is used as a method in this paper.In our quest for answers we use a theory of internationalization that we place in its context by primarily discussing the relation between globalization and regionalization. The theory is used as an explanatory force and to give it a concrete form we operationalised its three processes; internationalization of problems, internationalization of the societies and internationalization of the descisionmaking.The result of the case study shows that the increase in asylumseekers leads to a higher risk of negative competition wich give rise to the memberstates need to coordinate their politics.We found that when societies and problems are being internationalized, the state finds it difficult to resolve problems on their own and this leads to the internationalization of the dedescisionmaking. The internationalization of the decision-making process is therefore natural, which in this case means the decisions are taken by the EU rather than by the member states..

Värdeflödesanalys på Saab Training Systems i Huskvarna

Saab Training Systems (STS) in Huskvarna is manufacturing material for educationalpurposes to armies worldwide. They are now implementing parts of the Lean productionconcept in their organisation.One part of the work with Lean production is to eliminate waste. To be able to identify waste,value stream mapping is a good tool and also what we used in our thesis. To gain a betterefficiency in the production of Personnel Detector Device (PDD) flow was one of our goals.The PDD is a harness used during battle training which registers if the user is being hit by itsenemy.Our work with the thesis started up with a short education in Lean production and in valuestream mapping (VSM). The work proceeded with a VSM of the production flow of the PDD,interviews were made and studies of literature were done to gain greater knowledge of thesubject and solve the task.The VSM resulted in five areas which were followed up out of those six we identified.

Problem vid beslagtagande av egendom

This thesis takes its starting point in the 27 Chapter 1, section 1 of the Swedish code of judicial procedure, where the following is found:?objects reasonably presumed important to a criminal investigation or taken from a person through a criminal act or subject to criminal forfeiture may be seized?In this thesis we have investigated what kinds of problems occur when the seized object is part of an investigation of IT-related criminality. We have used methodological investigations of Swedish laws, legal usage, and the preliminary work with laws. Further have three interviews been made with different actors affected by or involved in seize of objects. These persons were a police officer, a public prosecutor, and a person whose object has been seized.The result we present is that there exist three kinds of problems related to objects that are seized within the demarcation of this study.

Värmeåtervinning på förskolan Rymdattacken 1 : En jämförelse av värmeväxlare

In the spring of 2014 Sweco Systems AB were commissioned to design a ventilation system for a newly built preschool in Linköping. Terms from the client was that it cost efficiency would cope with the energy demands that are placed on the building. The unit chosen was a cross-flow heat exchanger, and this work is to compare it with two other heat exchangers to see if a more energy and cost efficient could have been chosen. The heat exchangers that was chosen for the comparison was a rotating- and a counterflow heat exchanger. Simulations have been made to the different heat exchangers by the manufacturers.

How do you measure culture? -A case study of result control within the Gothenburg Opera

Problem The culture sector is characterized by qualitative goals which raise questions such as how do you measure culture and what is ?good? culture? Both the goals and the measurements tend to result in subjective judgments, which according to the theory make result control inefficient. Yet, result control is frequently used in the culture sector; which leads up to our research question: What characterizes the problems of result control in the culture sector?Purpose The aim of this study is to make a survey of how the Gothenburg Opera works with result control and follow-up. By defining how it tackles the different problems, which could arise with result control in a non-profit organisation, we aim to map how the problems regarding result control are characterized in the Gothenburg Opera.

Levbart transportsystem i Uppsala

In this thesis a transport system is sought after thatif realised in the city of Uppsala could provide bothwell-being to all its inhabitants and sustainability,here jointly refered to as liveability. It is found thatthe car dominated transport system that is inoperation today provides two fundamental values,namely accessibility in both time and space, whichsets it apart from other transport solutions. Thesetwo values are of immense importance for theliveability in our modern world. On the other handthe car dominated system decreases the liveabilityof Uppsala in several different ways. Some of theseproblems, it is argued, could be solved within thecar system, through the adoption of moreenvironmentally friendly cars etc., but otherproblems are inherent in the car system and willremain no matter what changes are made.

Dessa har sedan bedömts efter listor av deras respektive för- och nackdelar som kunnat urskiljas.Arbetet visar framtagandet av ett väl fungerande förslag som kan verka som en bas för idéer till nutida och framtida förändringar kring den fysiska planeringen.

Vägen mot säkerhet - får alla gå med? En kritisk, feministisk analys av det traditionella säkerhetsbegreppet.

In this essay I analyze the concepts security and security policy from a critical, feministic point of view. The traditional way of thinking security is state-centred and narrow with its military oriented threatening pictures and solutions.I advocate that the two concepts need a more feministic and holistic approach to be able to cope with the threats of our time and include the security for women explicitly.To suggest how this can be done I introduce a model; security-sphere, which should be seen as a way to constructively connect my objections to the existing research with a new approach to security problems. The security-sphere is based on two analytical parts; the private security sub-sphere and the public security sub-sphere, in order to make new images of security problems visible.It is a fact that most of the threats against women specifically, take place in the private sphere where no traditional analytical tools reach in - these threats have not been seen as 'real' security problems. My aim is therefore to integrate these issues into the agenda of security policy..

Kostnadskalkylering på en förpackningsavdelning

This degree project is based on identifying and allocation of costs in a packaging section at Electrolux Distriparts in Torsvik.The purpose of this thesis is to identify the costs that emerge when packaging different articles and show how the costs are allocated. The report also contains improvement suggestions about how the company can use the current computer system more efficient.The methods that have been used in order to approach the problem and the collection of information have mainly been literature study, interviews and observation.The work started with answering the questions; which expenditure cost and direct cost exist in the section, how can they be allocated, if improvement can be done and how the flow of information is supposed to happen.In order to answer the questions we used our former experience and the knowledge we achieved by reading literature, interview relevant persons in the company and observations carried out in the section.Through our studies, we came up with an Excel file, which is the groundwork for a template that can be used by the company in different occasions depending on the situation and need. It is important to remember to modify the template if the presumptions change. In the template, we have identified the different kind of costs that emerge when packaging different articles and we have also allocated the costs. In addition formulas and estimations that are necessary for the cost calculation are presented.The work consisted in making the groundwork for a template.

Hedersrelaterat våld : En studie om socialarbetares förståelse av hedersrelaterat våld

After the honor killings of Fadime and Pela, an extensively discussion started in the media, debating honor-related violence and oppression. This debate also made us, the authours of this paper, to pay attention to the problem. As a professional in social work, there are several good points to be made by having an in-depth knowledge in the field, both to discover individuals exposed to honor-related violence and to be able to protect them. The study was conducted by four qualitative interviews with professionals in social work with a professional experience of honor-related problems. Through the interviews, the social worker's view of honor problems emerged.
