The goal with this project was to achieve real-time synchronized video playback over the Internet, or in other words, that multiple clients play the same part of a video at the same time.The result shows how it is possible to build such a protocol, that gives a user experience that the video is synchronized between computers when playing a locally stored file, stream or video delivered using progressive download. This was achieved by designing, then role playing to find weaknesses, and at last implementing the protocols to see how they work in practice. By using such a protocol, it is possible to navigate and discuss around a video in for example a telephone conference, and be sure that everybody is looking on the same picture..

This report is the result of a thesis at the company Sanmina in O?rnsko?ldsvik. The thesis is the final work at the mechanical engineering program at Umea? University.Sanmina has in 2015 launched an initiative to ensure that all sites are using LEAN principles and tools to enhance their business. As part of the plan for the LEAN-work, an LSS (Lean Six Sigma)-project has started to study the company's receivehall and inspection.

In a time when milk producing farm businesses face decline in profitability it is of great importance to examine how the situation can be improved. This thesis is a study off efficiency in milk producing farm businesses represented by Swedish, Dutch and German farms. The aim of this study is to investigate whether any differences exist between companies in these countries. Moreover, the study includes a mapping of a number of factors that determine how efficient milk production can be managed. This mapping is based on a literature review on prior efficiency studies followed by qualitative interviews with milk production advisors as well as a questionnaire sent out to dairy farmers in Sweden.

The use of environmental management systems, and objectives-led corporate management have become a widespread phenomenon today. Identification and assessment of an organisation?s significant (environmental) aspects is crucial within this work. Identification and especially assessment of significant aspects is often considered as a problematic step in many organisations. There are no generally accepted methods how to undertake this crucial step.

Thesis purpose: The aim of this paper is to extend the knowledge of what influences the purchase decision of functional food in the store. By applying the M-R model in a new setting - the dairy department in grocery retailing in Sweden - and adding variables related to health attitudes, the aim is to contribute to existing research concerning in-store purchase decision making and store environment as well as consumer attitudes. Methodology: This thesis employs a quantitative strategy with a deductive approach and data has been collected with questionnaires. Theoretical perspective: Environmental psychology serves as an overarching framework where, more specifically, certain aspects of store atmospherics and some variables concomitant to health attitudes provide the theoretical base. Empirical data: The empirical data consists of customer purchasing a functional food product, Proviva, and this is contrasted with a test group, Bravo.

SummaryAimThe study examines a theoretical model developed to capture cyclist´s perceptions of the route environment. The survey focuses on if level two and three in the theoretical model captures what it´s intended to do. More specific we ask ourselves how the three appraisals (unsafe/safe by traffic reasons, stimulating/inhibiting route environment, unsafe/safe by other reasons) in the model´s second level relates among themselves and if these three appraisals can capture the degree of environmental well-being/unwell-being in the model´s third level. The questions were: Do the three appraisals differ among themselves? What is the difference/-s in such cases? And, is there a correlation between any of the three appraisals and environmental unwell-being/well-being? What is the correlation in such case? MethodThe gathering of data was done through questionnaires.

De flesta svenska gåsbestånden har ökat kraftigt de senaste decennierna, och de stannar ofta längre i Skåne innan och under flytt än vad de tidigare gjort. Detta har lett till ett ökat tryck på landskapet, särskilt i områden där stora flockar samlas som till exempel vid vattendrag. Syftet med studien är att illustrera vikten av gässens avföring med hänsyn till näringstillförsel i jämförelse med andra lokala näringskällor. Fyra dammar inventerades mellan maj 2004 och mars 2005..

Detta examensarbete har utförts inom borrstålstillverkningen på Sandvik Materials Technology (SMT) i Sandviken. Borrstål är en viktig produkt för SMT, vars efterfrågan har ökat stadigt under en lång tid och även i framtiden spås öka. SMT har länge strävat efter att höja leveransprecisionen på det borrstål som levereras, då leveransprecisionsmålet som i dagsläget ligger på 95 procent inte har uppnåtts på länge. SMT har även uttryckt önskemål om en kortare ledtid för tillverkningen av borrstål från råvara till kund, vilken historiskt sett uppskattats till åtta veckor.Syftet med examensarbetet är att, genom utförandet av en värdeflödesanalys, identifiera förbättringsförslag som kan effektivisera produktions- och planeringsprocessen vid ett tillverkande företag.De metoder som har använts för att utföra examensarbetet är litteraturstudier, observationer samt intervjuer. Utöver detta har prognos-, beställnings- och leveransdata samlats in med hjälp av de system som används på SMT samt även information kring cykeltider för de ingående processerna i borrstålsflödet.De mest tongivande teorierna som examensarbetet utgått ifrån och som författarna genomgående haft i åtanke är Lean Production, värdeflödesanalys, lagerstyrningsprinciper, linjebalansering och SMED.Genomförd kartläggning av nuläge och analys visar att kundernas prognos- och beställningsmönster inte stämmer överens av olika orsaker samt att balansen i borrstålsflödet inte är optimal.

The Multispectral Canopy Reflectance Model (MCRM) by Kuusk (1995) has beenused to simulate the reflectance of a sugarbeet canopy. The simulated reflectancevalues show high absorptance in the VIS area, compared to field measurements, andhigh reflectance values in the NIR area. The errors may be due to overestimation ofclorophyll content in the sugarbeet leaves and scattered light during fieldmeasurements. The estimation of the clorophyll content where carried out using thePROSPECT-model by Jacquemoud & Baret (1990).During the vegetation period, the state of the canopy moves towards a closed canopy,with sparse vegetation in spring. The MCRM-model was used to perform a ?spring?simulation, which was compared to the original simulation.

By studying a place or a phenomena research contributes to the creation of the image of the thing that he or she studies. Also, planning is seen as a democratic tool, a way to ?make? democracy. In order to see what democratic ideals that is being express it becomes important to study the research about democracy in Botkyrka. It is from this thinking this study about democracy and research has been formed.

 The sawmill industry is a relative fragmented industry that is in an economic upswing andwith a hard competition. The customers have high demands on their suppliers and the highcustomer demand make it necessary for the companies to make a streamlining in planningand production. For that reason it is very important that the planning- and productionprocesses aren?t to complex and with a simple structure.The purpose of this report is to study and map out a marked out part of a planning- andproduction process, from adjust works to final delivery, at a company in the sawmill industry.Different methods have been used for the report, among others interviews and subordinatedmaterial.We have mapped out a marked out part of the planning- and production process at theCompany. This part we have studied, and we have analysed the process it self and otherthings connected to the process.We see the planning- and production process in the Company as complex.

This thesis aims to investigate what requirements companies have in order to achieve a successful legislative compliance control. The implementation of an environmental management system can help the company to structure their business and succeed with their environmental legislative compliance.Both small and medium sized businesses perceive that it is difficult and time consuming because the legislation can be difficult to interpret if you do not have the required knowledge. There are many companies that hire help in the form of consultants who audit their compliance, but this leads to a risk that the company will be exposed when the knowledge does not remain in the company if the consultant would cancel the cooperation. There are not so many tools today for businesses to obtain good legal compliance. The methods used are usually checklists included in the control program, and it costs a lot of resources to do everything needed.This study strives to deliver the expressed needs of the businesses.

The purpose of this work, has been to examine how different actors in the Swedish eco movement and the Swedish forest industry looks at Sweden?s forest policy statement, which claims that environmental goals and production goals should be equal in Swedish forestry. By assembling focusgroups with participants from the Swedish eco movement and the Swedish forest industry, we look at if these participants consider the Swedish forest policy goals equal or not. Conflicts do occur between the two forest policy goals, but also between those and others of Sweden?s environmental goals.

 The aim and scope of this study is to describe the coordination of joint efforts concerning chemicals and hazardous substances in the Baltic Sea region, between the Swedish Chemicals Agency (KemI) and the land-based pollution group of the Helsinki Commission (HELCOM LAND). Based on the description of the coordination, the second aim is to discuss the consequences for the Swedish Chemicals Agency in its policy shaping work towards a nontoxic environment. A qualitative and descriptive case study method is used for this purpose. Theories of coordination and achievement-inducing criteria for environmental goals are applied to the case. Components and related processes of coordination are applied to the descriptive part of the study, whilst the achievement-inducing criteria are applied in the discussion.

We are more aware than ever about our impact on the common environment and the world's population. Consumption awareness can be one way to take social and environmental responsibility. This study aims to examine young adults' (19-30 years) attitudes toward consumption awareness in Sweden. Consumption awareness is treated in this study as the consumption of environmental and fair-trade labeled products that have been certified of a third party. The study is limited to everyday commodities, which in this case is groceries, household consumables and clothing.
