Grafisk utvecklingsplattform för signalbehandling - Design och implementation
We have different kinds of signal processing everywhere around us in our everyday life, in our cellphones, when we are listening to music, watching TV etc. This makes signal processing a very interesting and important technical area, where the demand of skilled engineers sets the limit of what is possible.Working with signal processing requires in-depth knowledge in areas such as mathematics, physics, electronics, and other related areas. For this, it has traditionally been demanded by a talented developer to also master the advanced programming languages such as C / C + + and Assembler.This has begun to change; today there are several companies that offer graphical development environments for signal processing, environments where programming skills are not needed anymore, and the focus can be on signal processing instead.The goal with this project is to build a corresponding graphical development environment to reach an understanding of what is required of these systems, and also to grasp what opportunities that are available within graphic programming. Inspiration for the work has partly arise from some of the tools available on the market, and partly from previous theses that have been written about graphic programming.The challenge lies in creating a program that can execute signal diagrams in real time from given signal blocks, and be able to handle feedback loops in an efficient way and to do so at the lowest "cost" in terms of clock cycles as possible. This should also be compared against to code, compile and run a complete signal diagram directly.To increase the usability it should also be possibility to externally manage in real time the parameters of the signal diagram during execution.The interface is a separate program, which is to some extent similar to Matlab Simulink, where a signal diagram is drawn up graphically by connecting wires between different signal blocks.
Konkurrenssituationen fo?r den svenska morotsbranschen :
The Swedish carrot market is dominated by a few big companies and three of them stands for
50 % of the market. During the last twenty years the number of growers has decreased, the
area and the harvest have increased. The big producers have invested in advanced and
expensive postharvest equipment that fulfils the high standards of the food industry. Few
carrot producers are members of an organisation and they keep contacts with there buyers one
by one. The buyers are mostly wholesalers and these have during a long period of time
decreased the number of suppliers.
Produktivitetsanalys ur ett LEAN-perspektiv : En studie hos OPPC, AstraZeneca
The objective of this thesis is to map the resources and methods used at the department OPPC, at AstraZeneca, and derived from that give suggestions on possible solutions that will increase their productivity.Mapping of the product flow, as well as gathering of process data, has mainly been done using observations, but consultation with the process technicians has also played a great role. Further have theoretical methods been used, based on literature studies, within the areas of Lean production and statistics.The work has incrementally gone forward since the steps taken has been restricted by the irregularity of production which led to the need of creating a fictive production flow. This has affected the lead-time calculations in the way that they are meant to give an indication, rather than an absolute truth, on how different methods described shall be used.The current state analysis showed multiple areas of improvement when defining capacity as value adding time in relation to total throughput time. Using the "standard scenario" as a basis showed that the actual production flow only constituted 50% of the total project time. Further it showed that the workflow contained more non-value adding activities than value adding activities, which is a result of how the work is distributed within the department as well as in the different projects.
Utomhusmiljön som en lärandemiljö : Sex förskolepedagogers syn på utomhuspedagogik och utomhusmatematik
Syftet med denna studie var att undersöka vilka möjligheter samt hinder pedagoger verksamma inom tre olikt profilerade förskolor ser med utomhuspedagogik och utomhusmatematik i förskolans verksamhet samt att lyfta fram likheter och skillnader i pedagogernas synsätt relaterat till förskoleprofilen.En kvalitativ forskningsansats har använts med intervju som metod. Sex pedagoger har intervjuats - två pedagoger på en Reggio Emilia - inspirerad förskola, två på en I ur och skur förskola samt två på två olika oprofilerade förskolor.Resultatet av studien bygger på vår tolkning av pedagogernas utsagor och visar att pedagogerna, oavsett profilering, ser övervägande fler möjligheter än hinder med utomhuspedagogiken och utomhusmatematiken. De möjligheter som framkommit i resultatet beskrivs med hjälp följande rubriker; konkret och sinnligt lärande, hälsa, socialt samspel, motorisk utveckling, eget ansvar, fysiska miljön, naturmaterial och pedagogens inställning. De hinder som resultatet pekar på är relaterade till faktorer som tid, personalbrist, material, väder och pedagogens inställning. Samtliga pedagoger ser möjligheter med den sinnliga inlärningen och den grovmotoriska träningen utomhus.

Blondinbella : en kritisk diskursanalys av Sveriges mest lästa bloggare
In his book Wittgenstein on Rules and Private Language (1982) Saul Kripke claims that Wittgenstein argues for a certain form of scepticism in his book Philosophical Investigations (1953), namely a new form of philosophical scepticism, a result of Wittgenstein´s idea of language as language games. Nihilism, scepticism of meaning or of concept, constitutive scepticism are other commentators´ different names of the same phenomenon. The philosophy of Wittgenstein accounts for how our words, including the words of mathematics, have no meaning and there are no a priori justified objective facts as to what I mean about a word. We follow the rules blindly and without justification. We are unable to find any facts against this proposal.
Artificiell Insemination (AI) hos hund : en sammanställning över användandet av seminering inom hundaveln i Sverige under åren 1995-2004
The use of artificial insemination (A.I.) as an alternative to normal mating in dog breeding in Sweden are controlled by regulations from the Swedish Board of Agriculture and by ethical rules assigned by the Swedish Kennel Club. Only veterinarians, who have a specific certificate and are specially trained and educated, are allowed to perform inseminations in dogs. Each artificial insemination must be documented and reported to the Swedish Kennel Club (SKK) which, on the behalf of the Swedish Board of Agriculture, yearly presents statistics concerning the use of A.I. in Sweden. The objective of this study was to illustrate the use of artificial insemination in dog breeding in Sweden for the last decade, using the yearly reports from the Kennel Club during the period of 1995 to 2004.
Landsbygdsturism och dess förutsättningar : en jämförandestudie kring vilka resurser som krävs för ett framgångsrikt entreprenörskap
Many jobs in rural areas have historically been linked to the agricultural sector. The restructuring that has been implemented in agriculture has resulted in a significant reduction in the number of jobs in rural areas. A consequence of this is that many people have moved to cities to earn a living. To maintain a living countryside in Sweden, it is therefore essential to create alternative livehoods in rural areas. An industry that can have a major impact in the future is rural tourism.
Köpare av skogsfastigheter i Småland år 2000-2001 : en undersökning hur den privata ägarstrukturen ser ut i Sverige
The aim of this thesis is to study the private owner structure in the Swedish forestry. This will be done with both a investigation of forest owners in Småland the year 2000 and 2001 and also a statistic research for the private forest owners in Sweden right now and over the years. In Sweden more than half of the total forest area is owned by private forest owner, witch is approximately 22 600 000 ha. Private forestry includes the owner categories private person, ordinary partnership and the estate of deceased persons. The main part of the private forestry is to be found in Norrland but also in the rest of Sweden private forestry constitute a large part of the forestry area.
Har graden av rörlighet någon betydelse för spänst och explosivitet vid hoppförmågan?
AbstraktDet finns blandade åsikter om att en grad av rörlighet över det normala skulle vara främjande eller hämmande för prestationen och därför var syftet i denna studie att mäta rörlighet och den maximala hoppförmågan hos gymnaster, cheerleaders och individer som utövar parkour för att undersöka om rörligheten har någon betydelse för spänst/ explosivitet. Undersökningsgruppen bestod av 15 friska deltagare varav 8 män och 7 kvinnor i åldrarna 18-32 år. Deltagarna genomförde tre Countermovement jump hopp (CMJ) och static jump där markering gjordes på en vägg för att mäta hopphöjd. Enbens längdhopp mättes också. Aktiv rörlighet mättes i fotled vid både dorsalflexion, plantarflexion och sit and reach (bakre rörelsekedjan).
En retrospektiv epidemiologisk studie om hudproblem på dobermann :
It is a well known fact today that suffering due to skin disorders is one of the most common causes to veterinary calls. For the Doberman breed included in the group of working dogs, the frequency and distribution of the different skinrelated diagnoses that causes visits to the veterinary clinics remains undocumented. The purpose of this study was to evaluate the frequency of skinrelated problems causing veterinary visits of Doberman at four different veterinaryclinics in Sweden retrospectively, and compare these results with dogs in general and three other working dog breeds with the help of information collected from Agria - a Swedish animal insurance company.
The total amount of veterinary calls that were registered at the clinics in question during the time of the study was 2460 visits. From these, 658 visits were due to skinrelated disorders, which amount to 27%. The most frequent cause to skinsuffering was injury caused by trauma, 15,7% of the Dobermans that were included in the study were affected, the second most frequent cause was inflammatory and infectious skin problems with 12,3% followed by neoplastic changes in the skin with 7% of the Dobermans affected.
Tillvaratagande och återanvändning av träbyggnadsmaterial : tjänstedesign för återbruk inom byggsektorn
The purpose of this Bachelor degree project is to design different types of services that can increase the amount of re-used timber within the building sector and by that means improve their environmental efforts. By examining how the sectors environmental work concerning recycling and re-using timber as a building material is getting on at present, conclusions have been drawn about what further could be done for improvement.The project has shown that there is a scarcity of information and statistics within the sector, but that there are efforts in progress to change this. Questionnaires have been sent to a number of companies working with demolition and utilizing re-usable materials in order to find out what kind of problems there are within the trade. Unfortunately the survey gave insufficient result due to the low reply frequency.It is obvious that active environmental work within the building sector is important and the knowledge acquired while working with the project has led to the design of three suggestions for services regarded as being of interest for improving the negative environmental impact caused by the sector:Suggestion 1 ? Sale of construction parts prior to the demolition of a buildingSuggestion 2 ? Re-utilization circulation when manufacturing buildingsSuggestion 3 ? Education in relation to the purchase of houses The positive and negative qualities of the suggestions have been examined with SWOT-analysis and further adaptions and the results have been interpreted.
Inte bara huvudet går i skolan- En studie av Waldorfpedagogikens undervisning och ursprung, med inriktning mot matematik för de tidigare skolåren
Denna studie behandlar en alternativ pedagogik och belyser ett alternativt arbetsätt till den kommunala skolan. Den pedagogik som behandlas är waldorfpedagogiken och den avhandlas allmänt och med en enskild del som är riktad mot waldorfskolans sätt att arbeta med matematikundervisningen i de lägre åldrarna. Waldorfskolans bakgrund och tankar beskrivs och även dess metodik och undervisningsinnehåll. En djupare studie i en alternativ pedagogik kan utveckla synen på undervisningsmetoder och få tips på hur man kan lägga upp undervisningen. Ett annat syfte är att skapa en förståelse varför waldorfpedagogerna arbetar som dom gör.
Lekens och inomhusmiljöns betydelse för barns lärande i förskolan : Förskollärares tankar och uppfattningar om lek, lärande och inomhusmiljö
ABSTRACT Poverty, and in particular child poverty, is a serious social problem. Statistics show that the number of children living in poverty has increased over the last ten years. Earlier research shows that there are huge gaps in our knowledge of how the actors in civil society handle child poverty. With this study we hope to help fill this gap. The aim of our study is to look at how four different organisations working in the civil society in Uppsala perceive and handle child poverty.
Att bedriva matematik : Sju lärares berättelser
ResuméArbetets art: Examensarbete i lärarutbildningen, avancerad nivå, 15 hpHögskolan SkövdeTitel: Att bedriva matematikundervisning ? Sju lärares berättelserSidantal: 38Författare: Angelica Dahlström & Anna-Karin FallgrenHandledare: Britt-Marie OlssonDatum: Januari 2008Nyckelord: Matematikundervisning ? TillvägagångssättSyftet med studien var att ta reda på vilka tillvägagångssätt lärare säger att de använder för att få eleverna att förstå matematik. Vi ville veta hur verksamma lärare undervisar sina elever i matematik och vad de har för argument för sina respektive val.Under vår lärarutbildning har vi blivit mer och mer intresserade av hur matematikundervisningen kan bedrivas på ett bättre sätt. Utifrån egna erfarenheter har vi noterat att många elever upplever matematikämnet som svårt, tråkigt och enformigt. Metoden vi använt oss av är kvalitativ, vi har intervjuat lärare för att få deras tankar kring matematikundervisning.
