The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

After a series of corporate scandals around the world the trust in the business world was damaged, probably most in the United States but also in Sweden. Voices were raised for an increase in the openness and insight into the affairs of the company whereupon different corporate governance codes were developed in a majority of countries. A Swedish corporate governance code was issued in December 2004 with the purpose to re-establish the damaged trust for the companies and the business world. The Swedish code was accepted by the Stockholm Stock Exchange as an exchange rule for A-listed and larger O-listed companies as of July 2005. The purpose of this essay is to study how the Swedish corporate governance code in fact leads to an increase in trust in the stock market and to study the companies? attitudes towards this code.To fulfil the purpose of this essay, the authors have carried out a survey among the concerned companies where the companies? attitudes towards the Swedish code were collected.

This thesis includes a review of scientific studies of tree injuries following mechanized thinning. Interviews have been made with drivers of single grip harvesters and forwarders in forest thinning and a number of essential factors have been identified as the most important to take into account in order to minimize and/orprevent injuries to stems and roots of remaining trees..

Web services are now a day often mentioned when speaking of systems communicating with each other online. This master thesis describes how we, with a grounded theory, developed a web service from scratch and then used it to describe how to develop a method for this case scenario. The purpose of the web service is to simplify the information exchange between Infra Gaming, which is the company who assigned this project to us, and their customers. This master thesis is not a guide to how you develop a web service. It is a master thesis that describes how we, in three steps, solved the assignment from Infra Gaming and our problem, with a web service..

The behaviour of the red-tailed guenon (Cercopithecus ascanius) was studied over the course of nine days in the Sabaringo forest surrounding Kichwa Tembo Tented Camp near the Masai Mara National Reserve, Kenya. A focal animal instantaneous sampling method with a one minute interval was used to record the behaviours of the monkeys for approximately 12 hours a day, the day being divided into six shifts á two hours. This method has proven successful in earlier studies of red-tails in this area. The study subjects included both lactating and non-lactating females, juveniles and on some occasions the resident male. The purpose of this study was to examine the grooming behaviour of red-tailed guenons and whether or not the occurrence of grooming varies depending on monkey type (lactating or non-lactating) and time of day.

Starch is a naturally occurring substance in most plants and is used as energy storage. It is a component that mainly consists of amylose and amylopectin. Together they build a complex pattern which gives starch its specific properties. The proportion of amylose and amylopectin varies in different plants but generally starch consists of 25 % amylose and 75 % amylopectin. There have been discoveries of barley varieties containing 100 % amylopectin called ?waxy starches? or ?waxy barley? as well as varieties that have a high content of amylose, around 70 % and these are called ?amylotypes?.

This report describes a Bachelor thesis work in which a robotised laser welding cell has been modelled and simulated for the purpose of making a presentation movie. The report shows that the work has been concentrated on making the movie from the modelling phase through the recording of the movie and ending up with the editing of the final presentation movie. A pre-study was made prior the Bachelor thesis work. In the pre-study a literature study was conducted about measurement and calibration of a welding cell. Measurement of almost all equipment in the entire cell was also conducted in the pre-study.

Detta examensarbete är genomförd som en explorativ fallstudie på ärendehanteringssystem för att se vilken påverkan dessa system har på företagen som använder dem. Tidigare forskning har visat många fördelar från enskilda funktioner inom ärendehantering och ärendehanteringssystem, men det finns en avsaknad av undersökningar som tittar på dessa system som helhet. Examensarbetet genomfördes som en så kallad single case fallstudie på ärendehanteringssystemet SupportPoint som är utvecklat av företaget Syscom..

Approximately 20% of the milk within the udder of a cow is stored in the cistern and immediately available for milk removal, while activation of the milk ejection reflex is required for removing the remaining milk stored in the alveolar compartment. The aim of this literature review is to describe, evaluate and consider implications of the three different suckling activities that the calf displays during a suckling bout. In terms of milking, these phases are represented by pre-stimulation, stimulation during milking and post-stimulation. Pre-stimulation is commonly performed in order to induce the milk ejection reflex, whereby the hormone oxytocin is released and the alveoli in the secretory tissue are contracted. Time requirements regarding pre-stimulation must be considered in relation to lactation stage and milking interval.

Virala orsaker till reproduktionsstörningar så som abort, resorption av foster och dödfödda valpar är hos hundar ofullständigt kartlagda. Herpesvirus är det agens som har studerats mest och är även ett välkänt abortagens på andra djurslag, däribland häst. Hundens herpesvirus (CHV-1) orsakar hos vuxna individer i regel endast milda respiratoriska symptom. Hos dräktiga djur kan viruset ge upphov till förlust av valpar och även orsaka en kraftig och dödlig infektion hos neonatala valpar. Precis som många andra herpesvirus kan CHV-1 ge upphov till en latent infektion som kan reaktiveras vid stress.

The aim of this study is to examine metaphors and what may be perceived as motif-circuits in Stig Dagerman?s play Den dödsdömde (The Man Condemned to Death) and the two short stories ?Den dödsdömde? (The Man Condemned to Death) and ?Mannen från Milesia? (The Man from Milesia). My intention is to discuss a single theme and identity-marks that unites all three works, using Paul Ricoeur?s The Rule of Metaphor (La mêtaphore vive) as well as the ?thematic critique? of Jean-Pierre Richard.What is metaphor for Ricoeur is for Richard themes (theme): an organizing principle, a sort of schedule around which a world is constituted. Hence, I find similarities between the motif-circuits, Ricoeur?s metaphor-theory and Richards?s themes.

The problem area was identified due to the fact that research within internal audit is fragmented and insufficient, simultaneously to internal audit becoming more common in the public debate. Crises and scandals in companies such as Enron in the US and Skandia in Sweden have resulted in new regulations regarding how companies should be governed. These regulations have been established in Sarbanes Oxley Act (SOX) in the US, and in Sweden the Swedish code for corporate governance will be implemented in 2005. The regulations imply that companies must provide sound internal control and to accomplish that, companies should have an auditing and consulting internal audit function. The Swedish code for corporate governance denotes that companies can decide to comply or explain why the code is not complied.

Conclusions: A myriad of interpretations are possible when studying and discussing a particular organizational culture. As culture can not be removed from its context, we illuminate the effects that the internationalization process has with regards to unifying the organizational culture in our particular setting studied. Maintaining however, that a reflexive look at this culture shows no single interpretation as being sufficient, we try to expose its richness and ambiguities through a three perspective approach..

The aim with this report was to exam and surveys the internal logistics of Proton Finishing?s production. The basic data should give the company suggestions of more efficient and improved internal logistics. We will also give from our perspective suggestions of improvement, which the company will be able to evaluate.To evaluate these problems we used different kinds of methods. A frequency study was made on the internal forklift.
