Prestationspåverkan av flerträdshantering i klena gallringar

The aim of this study is to investigate how multiple tree handling harvesters perform compared to earlier developed standards. The study shows that multiple tree handling harvesters are more efficient in thinnings stands with mean stock volumes less than 0,12 m3fub per stock. The increased efficiency is different for different mean stem classes. In stands with a mean stem volume of 0,04 m3fub per stock, the increase can be as high as 40 percent while it is about 10 percent in stands with a mean stem volume of 0,12 m3fub. Comparisons have been done between stands that are felled with partly limbed stands and stands without partly limbed assortments. The difference in performance is clear and shows that the partly limbed assortments strengthen the multiple tree handling harvesters positive effects in low dimension thinnings.

Analys samt förslag till effektivsering av patientflödet vid en vårdcentral

In the year of 2009 the conditions for managing primary healthcare in the region of Västra Götalandchanged. The decision was taken by the regional assembly and resulted in that the citizens since thenhave had the opportunity to choose which health care provider they preferto stay with. Along with thisdecision a new market for private health careproviders was established, which resulted inincreasedcompetition between the providers.In order to manage the competition, the health care providers arenow forced to be more efficient in their operations andalso to beeven more focused on their patients.Backa Läkarhusgruppen is an example of a private healthcare provider in the region of Västra Götaland.In the same way it is also an example of anorganizationin need of analysing their operations to seehowit can be further optimized to meet patient needs and expectations.The aim of this study is to analyse Backa Läkarhusgruppen?s organization and its operationsin the hopeoffinding suggestions whichwill improve the patient flow.To allocate and solve the problems thatBacka Läkarhus suffer from,an approach inspired by Lean Healthcare is used throughout the report.Some of themost significant problems that were identified within the organization are:?The synchronization of demand and capacity is inadequate.?Absence of standardized routines.?Absence of present leadership.To be able to improve the patient flow Backa Läkarhus needs to handle these identified problem areas.By synchronizing the staffing level in relation to the trends in demand a reduction in the patient?swaiting times and throughput time will be possible. Creating clear responsibilities and routines for thestaff will contribute to a higher degree of patient focus and thus lead to a more efficient patient flow.

Värdeflödesanalys som verktyg för effektivare byggproduktion: Studie över köksproduktionen

Rapporten består av en studie över köksproduktionen på ett stort svenskt bostadsföretag i Sverige. Studien är utförd med hjälp av verktyget värdeflödesanalys som är avsett för att hitta slöserier i en process. Processen som undersöks består av mottagning och inbärning av köken till lägenheterna samt hela montaget, i fyra olika projekt. Varje leverans är uppdelad i tre kök åt gången som kommer var fjärde dag. Denna leveranstakt är även den takttid som gäller för köksproduktionen, d.v.s.

Förstudie för produktionshöjande åtgärder: en fallstudie på
Munksunds sågverk, Piteå

Munksunds sågverk är ett högeffektivt furusågverk fokuserat på tillverkning av kundanpassat trä. Årsproduktionen 2004 var cirka 417 000 m3 sågad vara vilket motsvarar omkring 2430 m3 per anställd och år. Munkssundssågens mål för år 2009 är att öka sin produktion till 3300 m3 per man och år. Det innebär en ökning med cirka 36 procent jämfört med produktionen 2004. Syftet med detta examensarbete är att verifiera och prioritera parametrar som påverkar sågens effektivitet, samt att ta fram en åtgärdsplanering för att nå en produktionsökning med 36 procent till 2009.

Män som har sex med män ? utmaningar och strategier i svenskt utvecklingsarbete

Introduction: Men who have sex with men (MSM) is a vulnerable group with regard to HIVbecause of biological factors, lifestyle, discrimination and, in some parts of the world,criminalization. From a public health perspective it is important to include MSM in order to securea high-quality HIV prevention but also to safeguard human rights (HR) for this group. However, itis only recently that the Swedish development cooperation agencies have begun to integrate MSMin HIV prevention. Objective: To examine how employees of Swedish institutions responsible fordevelopment cooperation manage the vulnerable group MSM when providing support for HIVprevention programs and human rights programs. Topics relate to challenges and strategies tointegrate MSM in HIV prevention, which achievements have been obtained, and how to practicallydeal with the criminalization of the group.

Effektivisering av anbudsprocessen på Balfour Beatty Rail AB : Examensarbete, Innovativ produktion

Anbudsprocessen på Balfour Beatty Rail i Västerås står inför en förändring då man vill införa ett nätverksbaserat kalkyleringssystem. Examensarbetets avsikt är att fokusera på anbudsprocessen med fokus på kalkylarbetet för att se hur dessa kan effektiviseras, samt för att se hur arbetet med kalkyleringen ska utformas på bästa sätt vid övergången till den nya plattformen.För att komma fram till hur anbudsprocessen ska kunna förbättras och designas på bästa möjliga sätt har detta bland annat lösts med hjälp av semistrukturerade intervjuer med alla som är involverade, för att få en insyn in i processen på en detaljnivå som tillåtit mig att modellera processens utgångsläge. Då företaget har utryckt en önskan om att ?skapa en ?lean? anbudsprocess? har målet varit att förbättra processen med hjälp av den teori som är tillämplig (operations management, TQM, MIS, project management med mera) samt även att underbygga den med teori om lean enterprise och undersöka möjligheten för ett större åtagande av ett lean system.Efter undersökande av processen har en rad förbättringar föreslagits som till viss grad kunnats illustreras med en ny processkartläggning. För att optimera organisationens arbete med att producera anbud har det konstaterats att beslutsprocessen som leder fram till ett åtagande av produktion av anbud varit för lång och behöver effektiviseras genom att bland annat förbättra beslutsunderlaget innan ledningen träffas, att korta beslutsvägar och att ha möten minst två gånger i veckan.

Styrelsens användning av styrmedel -en jämförelse mellan entreprenöriella och icke-entreprenöriella företag

Management control systems are a popular area of research and a lot of new research has been done over the past years. This development has been looking into new situations and circumstances, and interdisciplinary studies are being made to further understand the connection between different fields of study. A new field of study that has grown significantly over the past few years is the connection between management control systems and entrepreneurship. Leading researchers have proposed a number of questions for further research and one of them is the board of directors? use of management control systems in entrepreneurial firms.The purpose of this study was to examine the differences and similarities in the board of directors? use of management control systems between entrepreneurial and non-entrepreneurial firms.The study was conducted as a deductive qualitative study through interviews with respondents from entrepreneurial and non-entrepreneurial firms.

 Hantering av personuppgifter ? en arbetsmiljöfråga?

Unhealthiness is not just a damaged back or asbestos. The fact that mental ill-health seems to increase in our society is well known. Statistics from Arbetsmiljöverket proves a fourfold increase of work-related disorders since 1997. These are primarily caused by organizational and social factors, 60% are considered caused by stress and a heavy workload. Sick leave due work related fatigue and depressions are scarily common today.

Utveckling av tidsplanering på JM: en studie av hur man kan
utveckla tidsplaneringen och planeringsmetodik med hjälp av
Line of Balance

Omkostnaderna för ett byggprojekt i produktionen är höga och beror på hur länge det varar. Idag skiljer sig tidplanerna mellan de olika platscheferna mycket när projekten är snarlika, vilket innebär stora skillnader på täckningsbidraget. Skillnaderna på tidplanen beror på att platscheferna planerar på olika sätt där de inte har klara styrdokument. Det finns ett intresse hos JM att utveckla tidsplanering då det är ett styrande verktyg som till stor del påverkar projektens ekonomi. För att kunna dra slutsatser har vi studerat planeringsmetodiken där det idag finns brister.

Utvärdering av en väggkonstruktion utan PE-folie : Med en undersökning av hårdvaxolja som diffusions-/konvektionsspärr

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

Samband mellan testosteron, DHEAS, kroppskomposition och fysiska kapaciteter hos unga kvinnliga fotbollsspelare

Testosterone is a steroid and anabolic hormone found in all mammals. Previous research indicates that testosterone levels correlates with physical capacities related to physical performance. However, these studies refers only to men and boys. The aim of present study was therefore to investigate the potential relationship between body composition, strength, power and endurance capabilities in relation to blood levels of testosterone and DHEAS in young female football players. Seventeen female elite football (age: 15,4 ± 0,6, body mass: 57,2 ± 7,4kg, height 1,65 ±0,04m) players volunteered for the study.

Solcellsdrivning av distribuerade inbyggda system

The high level of energy consumption that the industrialised countries have reached and thepollution that this brings has long been a cause for analysis and debate, development and usageof so called renewable energy sources is therefore more important than ever. The energy in theelectromagnetic radiation from the sun is an interesting alternative. One way of harvesting thisenergy is by using solar cells, devices that generate DC current when exposed to electromagneticradiation.The goal of this master?s thesis was to design a solar powered power supply to Syntronic AB?sMidrange platform. The envisioned application is a stand-alone distributed embedded system,for example a node-based temperature monitoring system.

Generationsskräpsamling med explicit kontroll av hårdvarucache

This report evaluates whether an interpreted high-level garbage collected language has enough information about its memory behaviour to make better cache decisions than modern general CPU hardware.With a generational garbage collector, depending on promotion algorithm and generation size, around 90% of all objects never leave the first generation. This report is based on the hypothesis that, because of the low promotion rate, accesses to higher generations are sufficiently rare not to benefit from caching.To test this hypothesis, we built an operating system with a Scheme interpreter in kernel mode, where the interpreter controls the cache. Generic x86 PC hardware was used, since it allows fine-grained control of cache decisions.Measurements of execution time in this interpreter show that disabling the cache for generations higher than the first does not give any performance gain, but rather a performance loss of up to 50%.We conclude that this interpreter design is not an improvement, but cannot conclude that the hypothesis is false in general. We suggest building a better CPU simulator to gather more data from which to make better caching decisions, moving internal interpreter data structures into the garbage collected heap and modifying the hardware to allow control in the currently rigid dimension of where data is cached---for example separate control of instruction and data caches and separate data caches for different areas of memory..

Utredning av fastighetsel i ett äldre och ett ombyggt flerbostadshus i Gävle

The residential and service sector in Sweden accounts for approximately 38% of the total energy usage and Sweden has an aim to reduce the total energy use by 20% by 2020 compared to 2008, which means residential sector will have to improve energy efficiency. As part of that a law was instituted by the Swedish parliament that all properties must have an Energy Performance Certificate (EPC) to thereby give the property owners a greater insight into energy use in their buildings and propose recommendations for energy-efficiency measures. On the EPC, a value on the building's energy performance in terms of energy use in kWh / m2 per year is declared, of which electricity is a share of it. Instructions on what to include in the amount facility electricity for running the facilities is regulated by the authority for building, Boverket while SVEBY has made an interpretation of the regulations in their report "Brukarindata bostäder" where they have a table on what should be included in the amount and what not to include.This report is a study of two similar apartment buildings, where one of the buildings recently underwent renovation, to see if the declared amount of energy for electricity, in the EPC, is consistent with the measured value, and whether there has been any reduction in facility electricity in the renovated building after the renovation.The result shows that the measured value of the building electricity was 2.6 kWh / m2 per year, 28,8 %, lower than the declared value in the building that have not undergone a renovation. Calculation of values from previous years (2011) by the same percentage of facility electricity as in the results of the measurements, 56.7%, it becomes clear that the declared value for facility electricity in the EPC of the renovated building do not correspond with reality and that there has been an increase in use of facility electricity after the renovation..

Databaser i molnet : En prestanda utvärdering

AbstractAs a developer of database-driven applications you will be faced with difficult choices, when it comes to choosing database, server and programming language. For the result to be satisfactory it requires the different techniques to interact well with each other and also fulfill performance expectations. This is even more important when the application is deployed to the cloud and the response time plays a major role.This paper evaluates different databases and their performance. To test the databases there was an application made in the server script language PHP or Hypertext Preprocessor and it was deployed to Windows Azure cloud platform. The test applications task is to call and load databases by controlled requests which creates, reads, updates and deletes data in an relatively large extent.The results shows that locale databases or databases in the same data center as the server generates the fastest response.
