Analys av mätdata från nätstationer

Fortum has in a pilot project installed metering equipment with wireless communication in secondary substations in Stockholm. So far, the collected data are used only in specific projects.This master thesis was carried out at Fortum Distribution AB in Stockholm during 2013. The purpose of this study is to simplify and enhance the use of data in for example network planning process, by giving suggestions on how data can be managed and giving examples of analyzes that collected data can be used for.The electricity meter which Fortum has installed is a EDMI-Mk10A which is set to Measure max/average/min values with a one hour time resolution of the following parameters: voltage (per phase), current (per phase) andactive power and active and reactive energy.In order to analyze the collected data an analysis tool is required. During this thesis two customized tools in Microsoft Excel have been developed, one for sorting data and one for analyzing.One aim of the thesis is to show examples of what collected Measurement data can be used for. This work shows an example of analysis of active power, power factor, voltage, occurrence of interrupts and the relationship between outdoor temperature and power.This master thesis has among others resulted in the following advice: Expand the number of secondary substations with measuring equipment.

Informativiteten kring finansiella instrument : En studie om hur informativt företag framställer sina instrument i årsredovisningen

The function of budgetary controls is to control the resource allocation within companies. It can also be an instrument for Measure and control subordinates and/or business units? performance (Van der Stede 2001). This paper concerns the latter; when the budgetary control function is used to Measure and control subordinates performance based on budget. Previous research in this area has not yet accomplished to explain the effects of tight budgetary control which Hartman (2000) considers as the main issue to be concerned about in management accounting research.Previous research has presented contradictory findings regarding tight budgetary control explained by positive effects as well as negative effects during the last decades.

Metodundersökning av tre metoder för kvävemätning i en arktisk äng : Jämförelse mellan mätmetoderna extraktion, inkubation och jonbytesmembran (PRS-sond)

The purpose with this report was to compare three commonly occurring methods for measuring plant available nitrogen in soils. The methods extraction, incubation and Plant root simulator (PRS) probe - an ion exchange membrane (Western Ag Innovations, Inc., Saskatoon, Canada) method were used and comparison between these methods were conducted. A full factorial experiment were set up in northern Finland with the treatments excluding herbivores, warming and fertilization to see how the inorganic nitrogen content in the soil was effected by the treatments. Soil cores were taken and from them a subsample was incubated for 18 days and thereafter analyzed for inorganic N in laboratory. PRS- probes were in the ground for 1 month.

Energieffektiviserande åtgärder i samband med renovering av flerbostadshus

In Sweden, a big part of the energy use is used in the housing sector. Political goals and targets are set up which the housing sector needs to work towards. Apartment buildings are a major part of the housing sector in Sweden and therefore reduction of energy use in these kinds of buildings are key to lower the energy use in Sweden. But there are not only political incentives to reduce the energy use. Some energy?saving Measures are directly profitable and should thus be performed.

Åtgärder för att minimera trafikbullers påverkan på ett rekreationsområde

The aim of this inquiry was to investigate the most appropriate Measures to reduce noise impacts from road traffic on the Nydala recreational area in Umeå municipality due to the planned re-routing of the E4 motorway to an existing road along this area. The sound environment is an important part in the experience when we are visiting recreational areas. Noise is not only disturbing; the liberty from unwanted sounds also allows us to perceive natural sounds that are a benefit for the cultural experience. Therefore it is important to take actions to protect this well used area from traffic noise. The reasonable options to avoid noise impact in this case are to lower the speed limit, using a noise reducing coating or use noise protection screens and walls.

Reaktionskrafter i dragarmarna på en traktors trepunktslyft : Teori och praktik

Tractors of today come equipped with a CAN-system. A CAN-system sends information from sensors to electronic control units who process the signals. The sensors Measure several interesting parameters such as force, pressure and speed for various components of the tractor. This thesis discuss a force sensor which is placed in the pivot of the tractors three point linkage, the sensor Measure the horizontal reaction force from the load that the tractor is exposed to. Signals from this sensor can be used to Measure the force from any implement that the tractor is exposed to during an operation.

Finns det ett samband mellan graden av upplevd arbetsrelaterad stress och copingstrategi hos grundskolepedagoger?

The purpose of this study was to examine whether there was any connection between coping strategies; emotional and cognitive strategy and perceived level of stress among primary school teachers in primary and middle school. It was also investigated whether there was a difference between full-time and part-time employees and perceived level of stress. As a theoretical background Lazarus' transaction theory of stress was used as an explanation of mental stress, Lazarus coping strategies for stress and Karasek?s and Theorell?s model of psychosocial work environment was used to explain unhealthy at work. To Measure coping we used Coping inventory resources and to Measure the stress we used Percieved stress scale.

Sensory nerve conduction studies in young adults for the expansion of a reference material

Neurography is the most objective and reliable Measure of the peripheral nerve function, and it is used to diagnose both local and generalized neuropathies. Neurography can Measure both motor and sensory nerve functions. The principle for sensory neurgraphy is to stimulate over the nerve and record proximal or distal from the stimulated electrode.At the Department of Clinical Neurophysiology, University Hospital Uppsala, a problem has been identified, in that young adult patients tend to show unexpected abnormal neurography values in relation to the expected, indicated by the reference limits, without clinical correlates. This concerns foremost the sensory amplitudes in median and ulnar nerves. The hypothesis is that the requirement of young adults? amplitudes is too high.

Globala och lokala sökmotorer: en utvärdering av Google, MSNSearch och Svesök

Coverage and the precision in result descriptions are also examined. The three selected search engines are Google, MSN Search and Svesök. 30 queries were tested against the search engines and the first 20 result descriptions and results were judged for relevancy. Relevancy was judged by a binary scale.

The Influence of Multiple Drivers on WOM Behavior in an Online Context - A quantitative study on what drives consumers to share word-of-mouth online

Word-of-mouth marketing (WOM) has been considered as one of the most effective marketing tools, yet the least understood. While its lucrative effects have been well proven in academic studies worldwide, little is yet known of why consumers engage in WOM, and what factors actually drive this sought-after behavior, particularly in an online context. While today's research lacks holistic views on the simultaneous effects of multiple WOM-drivers, this paper takes on a meta-analytic approach by building on the pertinent literature to construct an aggregated model, including several previously acknowledged drivers divided into two categories: (1) Brand related drivers and (2) Personal and situational drivers. The authors then empirically examine what drivers are the most influential on WOM in an online social media context. By doing so, this thesis does not only contribute to marketing managers' better understanding of online communications management, it also sheds light on the theoretical knowledge of the behavioral drivers of WOM.

Evaluering av återvinningseffektiviteten i Svensk Medicin och Google Scholar med medicinska frågor ur Fråga doktorn.

The purpose of this thesis is to evaluate and compare the retrieval effectiveness of two search engines on the Internet: Svensk Medicin and Google Scholar. Svensk Medicin is a medicine-specific search engine and Google Scholar specialises in indexing scholarly material. A set of 20 questions in four categories were used to conduct the searches with the search engines. Genuine medical information needs were selected from a question collection provided by the television program Fråga doktorn. The relevance of the first 10 retrieved documents was judged by using a binary scale and the Measure used was precision.

Prövning av måttet Läpp-till-Lyft (L-t-L) på vuxna utan sväljsvårigheter

Context: Lip-to-Lift (L-t-L) is a bedside-method for measuring oral transit time at swallow. It was designed for a swallowing examination of persons on nursing homes where weight loss was noted in people with average L-t-L-time >5 seconds (Sandin, 2005). The Measurement was validated and evaluated by Eriksson, Bremer Zerpe (2008).Objectives: The study objective was to examine L-t-L on a group of young adults without swallowing disorders and as to examine the inter- and intra-judgereliability of the Measure.Questions:What is the L-t-L-time for young adults without swallowing disorders?Are there any gender differences regarding L-t-L-time?How high is the inter/intra-judge reliability of L-t-L?Method: Examination of L-t-L-time was carried out on 20 young adults, aged 19-27 years, without swallowing disorders after Sandin?s (2005) instructions. Measurements of 20 swallows per person were made.Results: The average L-t-L-time of young adults without deglutition-difficulties was 1.13 seconds (sd =.14).
