Lake Bornsjön is situated 30 km southwest of Stockholm in a rift valley lake and consist three basins outstretched in northwest-southeast direction. The surface area is 6,7 km2 with a maximum depth of 18,3 meters, a mean depth of 9,8 meters and a retention time of the water of 6,5 years. The drainage area is 42 km2 and consists mainly of arable land (ca 1000 ha) and productive forestry land (2500 ha), but in the drainage area there are also restored and fairly newly constructed wetlands.Today the Stockholm area receives its drinking water from Lake Mälaren, but if there would be any pollution of this source, Lake Bornsjön would act as the water source. The area surrounding the lake was bought already in 1899 by Stockholm Stad for protection of the lake and was taken over 1993 by Stockholm Vatten AB. It has been a water protection area from 1988 and it was also accepted as a nature reserve in 1995.

In East Africa live two species of Griffon Vultures; Rüppel?s Griffon Vulture (Gyps rueppellii) and African White-backed Griffon Vulture (G. africanus). One of the apparently most important factors limiting the population of these birds is food supply. Griffon vultures nest for eight months of the year, and are during this period geographically tied down to the nesting place.

In many clinical applications, it is desirable to transmit sensor information wireless. In earlier research, investigation transmit ECG signal using Bluetooth, was performed. However, when Bluetooth has some drawbacks it is of interest to investigate alternative methods, one such method is ZigBee. Bluetooth has higher data rate speed (1Mbps) than ZigBee (250kbps). However, Bluetooth consumes more power.

I en värld full av teknik och information som flödar är det viktigt att ha kontroll över den data som anses vara viktig för organisationen. Skulle informationen hamna i orätta händer kan det innebära förödande konsekvenser för organisationen och i vissa fall även deras kunder. För att undvika detta bör rätt sorts skydd anpassas till den typ av data man avser att skydda men även organisationen som helhet. Aspekter som frekvens och förödelse vid ett hot men även hur viktig datan är, är olika aspekter som måste utvärderas för att kunna anpassa och investera i rätt typ av skydd. Denna studie jämför två svenska IT-relaterade företag i varierande storlekar med avsikten att undersöka om det finns en relation mellan datasäkerhetsmedvetandet och företagens storlek, eller om det finns en annan relation som påverkar graden av säkerhetsmedvetenhet i en organisation.

Det finns ett behov att hitta och rekrytera skickliga spelare till sin fotbollsklubb på ett kostnadseffektivt sätt. Den nuvarande processen med talangscouter är tidsödande och kostsam. Automatiserad dataanalys kan underlätta sökandet efter de önskade spelarna. Då automatiserad dataanalys med semifiktiv data inte undersökts i någon större utsträckning tidigare hade det varit intressant att ta reda på hur väl vanliga tekniker inom data mining fungerar när de appliceras på semifiktiv data.Ändamålet med studien var att med hjälp av kvantitativa experiment skapa prediktiva modeller som förutspår om en fotbollsspelare kommer att öka sina marknadsandelar i framtiden. Studien hade även för avsikt att ta reda på om det, med hjälp av semifiktiv data, gick att skapa tolkningsbara modeller som gav generella insikter om viktiga attribut hos fotbollsspelare på olika positioner.Studiens forskningsmetod var kvantitativ forskning då det är en metod som värdesätter struktur och objektivitet; vilket var viktigt för studien och dess forskningsfrågor.

Abstract Tutor - Anders Richtnér History - Theories suggest that Lean Product Development strategies dramatically increase a company's performance through enabling faster T-T-M, Quality and Costs of Product Development. Purpose - The purpose of this paper is therefore to investigate whether the implementation of LPD actually affect corporate performance measurements T-T-M, Quality and Cost, in a positive way. Methodology - This Bachelor thesis is an exploratory investigation of the concept of Lean Product Development within a global IT- company, performed through four case studies, interviews and complementing corporate performance data. Findings - With empirical data and subsequent analyzes in mind, we note the following; it is clear that the project that produced the best results, in terms of T-T-M, Quality and Cost, also was the one furthest in the process of implementing Lean Product Development..

Syftet med denna uppsats är att modellera och prognostisera Sveriges varuexport, varuimport och handelsnetto. Vi använder oss av data från januari 1975 till och med augusti 2010 för respektive serie. Dessa data testas och jämförs i olika ARIMA- och SARIMA-modeller samt skattas även medelst säsongsreningsprogrammet TRAMO/SEATS. För de modeller som bäst passar serierna genomförs därefter in sample- och out of sample-analyser med felmåtten RMSE och MAPE. Modellerna med bäst felmått och som därpå väljs ut för att göra prognoser för serierna till och med augusti 2012 är (3,1,0)x(0,1,1) för export, (2,1,1)x(0,1,1) för import samt (0,1,1)x(0,1,1) skattad i TRAMO/SEATS för handelsnetto..

This thesis deals with the leisure-time reading of fourteen men with two different occupations, teachers of technology and directors of companies. The main reasons for writing the thesis are that very little is written about mens reading habits and also statistics that tell that mens reading decline regardless of educational level. The purpose has been to compare the reading and relations to literature between the two groups of men and to find out if any differences have to do with factors such as social background or age. The questions we have asked our collected data has been what, how and why the men read. We have tried not to investigate the work-related reading although we are aware of the difficulty in separating this from the leisure-time reading.

This paper examines the opportunities and challenges of integrating conservation practice and the circular economy into practical planning processes. In recent years, the discussion of circular economy and its relevance in the sustainability debate has intensified. According to the Swedish Environmental Protection Agency, the transition to a circular economy is crucial to achieving the national and international environmental and climate goals as well as the global goals in Agenda 2030. Parallel to this, there is a long established heritage discourse that emphasizes the importance of preserving buildings and cultural environments as part of our cultural heritage. These two discourses have common goals, but they differ in how they present their respective arguments.

Syftet med detta arbete är att simulera ett värmesystem i COMSOL Multiphysics, Pipe Flow Module, Non-Isothermal Pipe Flow som innehåller ekvationer och randvillkor för att modellera inkompressibel strömning och värmeöverföring i rör.Data om processen och dess komponenter har samlats in från industrin där arbetet är utfört och i vissa fall modifierats för att bättre beskrivas i programmet.Utifrån insamlad data har en modell byggts upp och två simuleringar har gjorts. En stationär för starten av systemet, den har sedan legat till grund för en dynamisk som simulerar förloppet från start till normaldrift.Tiden det tar för det aktuella fallet att nå drifttemperatur är 16 timmar. En felströmning upptäcktes samt att en av pumparna inte kommer att klara en start från 20 °C..

The purpose of this thesis was to examine if users of digital music games may acquire skills from the games that may be of use in learning to play a real instrument, that is a non-digitally simulated instrument like an acoustic piano. We have used Gee?s theory regarding a possible interconnection between different semiotic domains, and how this connection may enable a transfer of skills between related domains. In this thesis we examine possible skill transfer between the domains ?digital games? and ?non-digital instruments?. To examine our question formulation we chose to conduct a pilot study from which we collected both quantitative and qualitative data.

Earlier studies and research on the subject of perception and social media during the working process resulted in a change of the problem. At first the focus of the study was to examine how social media affects the perception of a brand although later on the problem had to be developed to instead examine if social media reflects the perception of a brand. The purpose of this study is to figure out if social media reflects consumer?s perception of a brand. This will contribute to company?s knowledge on how important social media is in their branding and will give pointers on how many resources that is necessary to spend on branding in social media.

High quality within a Lean production system begins with standardised work, which creates stable processes able to generate predictable output. If nonconformity from the standard procedures occurs, routines are needed to analyse, correct and prevent the nonconformity from occurring again. In that way, the nonconformity can be a trigger for continuous improvements toward more stable processes. In takted production lines, where the operator follows a standard sequence with tasks set to be completed within the takt time, a nonconformity leads to downtime in the operator?s sequence, and no value is added.

In Northen Bungoma, Western province ? Kenya, the Vi-Agroforestry Project (VI-AFP) has introduced a new project that covers 7000 households. To succeed with the project, a water resources protection project, agroforestry methods will be implemented to secure the water quality of the area. In this thesis a foundation is laid for future follow-up studies of land cover and land use of this area. To carry out this study an existing method from a cooperation between VIAFP and Dalarnas University (HDa) has been implemented.

Calculations of net present value are based on a discount rate, which requires knowledge about the company?s cost of debt. A common way to do this is by observing the company?s credit rating, when no credit rating is given it?s possible to use a synthetic rating model based on quantitative data to estimate a credit rating. Thus, the aim of this study is to increase the understanding of which quantitative data, in terms of key figures, that can be used to explain the given credit ratings for companies from the Nordic countries.In developing the model, key figures found significant in previous studies are being tested for whether or not they are applicable for companies from the Nordic countries.
