Denna rapport analyserar ekosläckning för en full duplex högtalartelefon. Systemet bygger på en LMS-algoritm som har implementerats på en TMS320C3 1 signalprocessor. Arbetet har gått ut på att undertrycka ekon genom utnyttja så mycket som möjligt av processoms kapacitet. Möjligheterna för att två eller fler personer skall kunna tala med varandra på att ledigt sätt genom en högtalartelefon påverkas mycket av de ekon som finns i systemet. Högtalartelefonens mikrofon fångar upp ljudet ifrån sin egen högtalare och skickar detta ljud tillbaka genom telefonnätet. Utan någon form av ekokontroll uppstår ett irriterande eko av sin egen röst i telefonen. Ju längre fardröjning som telefonnätet tillför, ju mer irriterande blir ekot. Konventionella högtalartelefoner använder röstaktivering av mikrofonen för att bli av med ekot.

This degree project studied surface waters on Kåbo Golf Course in Uppsala, Sweden, with the aim of determining the status of the water and how it is affected by the activities of the golf club, and to obtain suggestions of measures to create better conditions for the water environment on and around the golf course. The project forms part of the environmental protection work of Kåbo Golf Club, which is working towards achieving environmental certification from the Swedish Golf Association (SGF). The study is based on literature studies and quantitative and qualitative field studies of water on the golf course, with the focus on environmental factors identified as being important for the golf industry and on strategic environmental goals developed by SGF. The number of open water bodies in the Swedish landscape has substantially declined during the past 200 years, so it is important to save those that remain. This study showed that the surface water at Kåbo Golf Course is an important element in the surroundings since the area contains few wetlands, which can be a habitat for large numbers of species. The stream and ponds on Kåbo Golf Course also have the important function of serving as water hazards in the game and adding difficulty and variety to the course. Since Kåbo Golf Club wants its surface waters to look aesthetically appealing, extensive algal growth and drying up of ponds during parts of the year are regarded as problems.

Aim Developmental Coordination Disorder Questionnaire 2007 (DCDQ'07) is an international survey tool based on parents' estimation of their child's motor coordination skills. The purpose of this study was to investigate the validity of a Swedish version of DCDQ'07 by finding out how the classification of Developmental Coordination Disorder (DCD) via DCDQ'07 is consistent with the classification of DCD via the motor impairment test, Movement ABC.MethodIn the context of a larger study, a Swedish translated version of the parent survey DCDQ'07 were sent to 4000 randomly selected families with children aged 8 - 10 years in Stockholm County. The classifications "DCD" or "NOT DCD" with cut-off values ??of 56 (9 years) and 57 (10 years) were applied. Forty families were selected from 410 registered responses.

The Swedish Lapphund is one of our eleven Swedish domestic breeds of dogs and one of Sweden?s oldest dogbreeds. The Finnish Lapphund?s origin and physical conformation is similar to that of the Swedish Lapphund. One aim of this study was to examine whether the average litter size differs between these two closely related breeds, and if so, try to find causes for this.

The title of the study is: "Stories about helpful conversations - a narrative study of active processes in therapy and treatment." The purpose of this study was to examine clients' stories of what has been helpful to them in therapy / treatment. The study has been made in light of the ongoing discussion in society about the requirements for empirical studies within welfare areas. The choice to make a narrative study comes from the desire to have clients' own stories at the centre of what has been helpful in the therapeutic process. The author has interviewed and talked with four people (clients) who told us about their experiences of therapy / treatment. Narrative research methodology is based on people's life stories.

This is a tale about energy and power. It describes the geographer Halford Mackinder?s geopolitical theories and compares them with current views outlined by Zbigniew Brzezinski and Michael T Klare, among others. With a critical approach it also provides a historical account of a Europe that stands in front of an energy struggle so severe that the current world order seems destined to fall. Oil and natural gas, has since the beginning of the 20th century, been used as a geopolitical tool in order to create dependence, control and even sometimes overthrow empires.

The different aspects of each individual construction project such as the general conditions, design and economic restrictions as well as many more factors mean it is difficult to standardize building processes or plan in detail based on past experiences. As a result operational efficiency is often reduced, and unnecessary waste is generated. To make an organization more efficient and therefore reduce waste production everybody involved needs to appreciate and understand the improvements that can increase the organization?s efficiency. To investigate these improvements a time study was performed on two different construction sites, both of which involved buildings being constructed of prefabricated steel and concrete elements.

Multinationella företag och utländska direktinvesteringar blev ett nytt fenomen efter slutet på andra världskriget. En revolutionerande globalisering började ta form där företag ökade sina marknadsandelar genom investering och flytt till nya marknader. Denna globalisering kom inte att ske på Irland förrän på mitten av 1960-talet. Innan dess var landet slutet och nästan varken någon export eller import skedde. Idag har Irland blivit ett av de mest framgångsrika länderna i världen med att locka till sig utländska direktinvesteringar och multinationella företag.

To enjoy the richness of the grazing cows and high yield during the summers, even during the winter, cheese has been the way to store milk for thousands of years. Nowadays yield is high all year around and the cheese production is possible during all seasons. The aim of this paper is to investi-gate how and why the seasons influence taste and texture of pressed and ripened cheese. Milk is composed of proteins, fat, lactose and water but contains also a lot of vitamins. The quality of milk is very important for the final constitution of cheese.

This master thesis deals with two case studies in environmental archaeology and battlefield archaeology focusing on two major events in the late history of the Swedish coastal town Umeå and its nearby village Sävar. Established in the early 1600's, Umeå was known for its export of timber and import of cereals. The town has suffered from numerous fires, the fire in 1888 being the most devastating. Few written records of the town remain from before the 1900's. The latest war in Sweden's history is documented in historical sources and took place at Krutbrånet, Sävar where the Swedish troops suffered defeat against the russian forces in 1809.

The purpose of the essay Multi criteria analysis of potential conflicts concerning land use planning - natural stone mining in Lysekil municipal is to study possibilities and limitations in GIS based multi criteria analysis as a tool for land use planning. How GIS based multi criteria analysis can be implemented to localize potential conflict areas between natural stone mining and other land use activities and what advantages and disadvantages the method holds are the main issues of this study. The essay studies these questions through a case study, concerning the geographical area of Lysekil municipal in western Sweden and problematizes the interest of natural stone mining in relation to other land use interests. A literature study was carried through, concerning multi criteria analysis and planning. After collecting and processing of data the multi criteria analysis could be implemented in the ArcGIS tool Weighted Sum.

The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by pasteurization at 70°C in order to kill pathogens. Another method, integrated thermophilic sanitation (ITS), is of interest in order to decrease the energy demand. The method implies that the substrate is sanitized during ten hours in the digestion chamber, where the temperature is 52°C.

SammanfattningDen här rapporten beskriver arbetet att ta fram försöksmaterial i form av 3D-modeller med tillhörande animationer till det Internetbaserade rådgivningsverktyget för läkemedelsprodukter AssistansPlus*. Utöver detta ger rapporten en inblick i hur framtagning av 3D-medierat material för Internet, inom området rådgivning och presentation, kan se ut generellt.Viktigt att tänka på vid arbetet med modeller och animationer till AssistansPlus är att de måste anpassas till W3D formatet, som 3D spelaren i verktyget är utvecklad i. De viktigaste var här att veta vad som följde med vid en export till formatet W3D (animerandet måste ske på ett relativt analogt sett, vissa bildformat för texturerna fungerar bättre än andra etc.). Rapporten innehåller en checklista som ska fungera som en guide vid framtida framtagning av material till verktyget. Filstorlek är av stor vikt i arbete med 3D för Internet och var därför en viktig del också i uppdraget.Att begränsa filernas storlek genom att använda så få ytor som möjligt, genom att stiliseramodellerna och genom att göra texturer så bra som möjligt i förhållande till filstorleken, var viktiga delar arbetet.
