Trådlös kamerastyrning

As an amateur it can be difficult filming from several angles at the same time as this requires several cameras. It´s also hard to film at occasions when it´s not appropriate to manoeuvre the camera manually. Systems for solving these problems already exist, but it´s either more expensive, professionalsystems or cheaper systems with limited functionality.The purpose of this project is to develop a cost efficient solution to the problem above that offers a better functionality then existing commercial systems. The biggest difference from existing products is the wireless video feedback from the camera to the remote unit.The result of the project is a system consisting of two units, a manoeuvre unit with a cradle for the video camera and a remote unit from which the operator can control pan and tilt of the video camera.Communication between the two units is wireless.On the remote unit there is a joystick and a display mounted. In addition to this, there is also an IR receiver that is capable of reading the signal from the cameras own remote and sending it to the manoeuvre unit.The manoeuvre unit is equipped with one motor to control the tilt function and one motor to control the pan.

Vilken läsförståelse är det som bedöms?

Denna examensuppsats skrevs under utbildningen på speciallärarprogrammet på Malmö Högskola under våren 2015. Det är en kvalitativ studie som utgår från det sociokulturella perspektivet där talet är tankens redskap. Jag har genom fokusgrupper och lärarnas reflektioner i form av dokument samlat in min empiri. Det insamlade materialet har jag analyserat utifrån Kintsch och Rawsons modell för läsförståelseprocessen och bedömningens olika former. Mitt resultat visar på att lärarna, när de bedömer elever, bedömer hur väl eleverna kan genomföra olika aktiviteter kopplade till läsförståelse.

Balanserade styrkort: en fallstudie om varför företag frångår användandet av styrkort

I förundersökningen av balanserade styrkort upptäckte vi tidigt att flera företag frångått modellen efter en kort tids användning, trots litteraturens positiva framställning av den. Vi ställde oss då frågorna när företag väljer att frångå tillämpningen och utvecklingen av balanserade styrkort samt vilka faktorer som påverkar detta beslut. Syftet med uppsatsen blev att genom att jämföra företag förstå vilka faktorer som kan påverka företag att avbryta vidareutvecklingen av styrkortet. Vi valde att fokusera på implementeringen och vidareutvecklingen av balanserade styrkort. Uppsatsen grundar sig på en fallstudie av två företag, Plastic Technology Composites i Kåge och Centek i Luleå, samt intervjuer med två mycket kunniga personer inom ämnesområdet, Christian Ax på Handelshögskolan i Göteborg och Nils-Göran Olve på Linköpings Universitet.

Undersökning av förlustförändringar i lågspänningsnät uppkomna av mikroproduktion med solceller

Detta examensarbete har utförts på Vattenfall Eldistribution AB i Trollhättan och syftar till att beräkna förlustförändringarna i lågspänningsnätet då mikroproduktion i form av solceller ansluts.Genom att ansluta mikroproduktion i lågspänningsnätet kan nätets energiförluster reduceras. Denna reducering samt den energi som inte behöver överföras från överliggande nät anses vara den nätnytta solceller ger upphov till.Samtliga elproducenter som är anslutna till elnätet har rätt till ersättning för nätnytta uppkommen av produktionen. Ersättningen skall baseras på inmatad energi samt vid vilken tidpunkt inmatningen sker. För mikroproducenter är det svårt att motivera att i varje enskilt fall beräkna nätnyttan, varför ett generellt schablonvärde beräknats för Vattenfalls lågspänningsnät. Beräkningen har utförts utifrån uppmätta sol- och lastdata på sex olika lågspänningsnät vilka tillsammans anses representera ett generellt nät.

Jämförelse av solhybrider

Research in solar energy is taking big steps in both solar heating and solar electricity. It´s not only the technologies alone, but also the combination of both solar electricity and solar heating which is what is called a solar hybrid. The idea of a solar hybrid is that a solar cells efficiency decrease with increased temperature and can with help from a solar collector be cooled and the heat can be utilized. This thesis report compares heat production and electricity production with respect of, in first hand, a solar hybrids geometry in the cooler. The theory chapter describes solar heating and how different solar cell technologies work and their environmental impact at the production and how compatible these technologies are for the solar hybrid.

Portfolio som arbetsverktyg i förskola och skola - barns beskrivningar av sin portfolio

The study sheds light on pupils individual plans of development and portfolios from the perspective of children. It has an ethnographic standpoint. It was carried out on children and pupils in pre-school, pre-school class and third grade. By further investigating how children and pupils use their individual development plans and portfolios, in which settings and to whom they communicate them, this study is able to grasp the discourse that is created around the instrument itself. This study is also interested in and aims to find the theoretical frame, in essence, which envelops both the construction of childhood and children?s own activities within the limitations and opportunities that this structure offers.

En berg- och dalbana av genusstrategier : En studie om den normativa genusbildens konsekvenser för kvinnor med erfarenhet av narkotikamissbruk.

A qualitative interview study how the normative gender images affects on women, their roles and positions in a drug abuse. The purpose of this study aims to shed a light at the consequences that the normative gender scenario inflicts on women with drug abuse and how these prejudices affects these women. Based on interviews with four different women who all lived with a drug abuse we have problematized how the gender system and the normative gender images affected them. We have used gender perspectives and social constructivism theories while analyzing the empirical basis. More specifically we use the theories of Butler about how gender constructs through performative actions and Hirdmans theories of the gender system.

Revisionsplikt i mikroföretag : ett förebyggande kontrollsystem mot ekonomisk brottslighet?

Background & Problem: The Statutory audit was initiated in the beginning of 1983 with the argument that it had a preventative affect against economic crimes. It is discussed whether the statutory audit should be abolished considering it brings major costs for small limited companies, also there are discussions however easing the regulation for these companies. What effect would it impose for the preventative work against economic crimes if the statutory audit is abolished?Purpose: The purpose with this study is to learn how an abolishment of the statutory audit among so called micro businesses will affect authorities? preventive work against the economic crimes.Demarcate: The study is demarcated to comprise only authorities that work with preventing economic crimes with help of the statutory audit and that will be affected of an possible abolishment, such as the Swedish Tax Office (Skatteverket) and the Swedish National Economic Crimes Bureau (Ekobrottsmynigheten).Methodology: The research is based on a qualitative approach with personal interviews with two representatives from each authority. The gathering of data has been done by researching literature and databases.Conclusions: The result shows that the statutory audit is significant for the authorities and their preventive work.

Plockanalys i Härjedalens kommun : En utvärdering av plockanalyser på hushållens säck-och kärlavfall under åren 2007-2011

As a result of an increased consumption, waste volumes has grown steadily throughout the 1900s, and this puts great demands on an efficient and ecological sustainable waste management on both local and national level. In order to evaluate collection and disposal of household waste, a large number of Sweden´s municipalities are using waste analyses. The overall aim of this study has been to summarize and assess results from waste analyses executed in Härjedalen´s municipality during the years 2007-2011.The evaluation has given information about the household waste´s composition, quantity and change in time. The report´s objective has been to create a basis which the municipality can use in planning of future information efforts and other measures, and give some proposals on how these can be designed and targeted. Therefore, the report also highlights research on motivations factors that affects environmentally conscious behavior such as recycling, and how different instruments like information can be used to promote this.

Prediktion av elproduktion : Modellering av icke reglerbara vattenkraftverk

The main objective of this study is to divide a number of colorectal cancer cases into subgroups based on their molecular features using cluster analysis. The data used is supplied by a research group at Pathology, the Department of Medical Biosciences, Umeå University, and consists, after some preparation, of 455 observations which is a larger data set than many similar studies. The molecular variables that the clustering is based on are CIMP (CpG Island Methylator Phenotype), MSI (Micro Satellite Instability), BRAF- and KRAS-mutations. These are categorical variables and consequently the clustering method used is PAM (Partitioning Around Medoids) which is particularly useful with data on diverse variable level. The final analysis results in four subgroups that are represented by different combinations of attributes on the aforementioned variables.

Utvärdering av den gröna smileyn inom livsmedelsinspektion : En intervju och enkätstudie i Halmstads kommun

With a growing population on earth the amount of end-of-life vehicles (ELVs) and other scrap steel increases. The European Directive 2000/53/CE? requires a minimum of 95 % reuse and recovery and 85 % re-use and recycling no later than 1 January 2015, for end-of life vehicles. This imposes a need for more efficient recycling and recovery. Despite this shredder residue (SR) is commonly land filled.This report investigated the magnetic fines residue generated at Stena Metall shredder facility in Halmstad, Sweden.

Hur mikrofinanser genererar empowerment hos kvinnor i utvecklingsländer : Pengar med ett syfte

Social work as an traditional aid is an area that provides welfare services financed from public funds, which is one of the methods of microloans. Microloans have since the mid-1970s has become an increasingly common tool in the fight against poverty. Instead of purely assistance is now offered microloans from more banks and other institutions, as well as NGOs (non governmental organization). This paper aims to study whether and how microcredit can contribute to the empowerment of women in Bangladesh and India. This study is based on a qualitative text analysis, and has hence been based on a number of reports and articles. The paper examines, from a radical feminist perspective how microcredit can fight and eliminate poverty, and how empowerment can help women in developing countries to become independent and liberated. The introduction of micro-loan is considered to have positive effects on women's empowerment in the short term. But it is, however, the longer term effects that are considered to have the greatest positive impact on society's unequal structures.
