Lågoffsetkomparator
Detecting small signals with a comparator demands that the total voltage offset is lower than the actual signal. The total offset includes the voltage offset in the comparator and the voltage offset that is created by the offset currents that flows thru the load at the comparators input. The goal with this comparator that has been developed has been that it will have a total voltage offset at maximum 500 uV. The comparator does not need to be extremely fast or does not need to operate in a big frequency area. To have all the flexibility that is needed a full custom technique is used.
Minoritetsproblem i Östeuropa : EU:s relation till Slovakien
The aim of this thesis is to study the situation of minorities in Slovakia before and after the EU-membership and if EU has played a role in the situation. Also the criteria for becoming a member and other treaties regarding protection of minorities between European institutions and the accession/member states are studied. With the help of i.e. literature, relevant internet pages and yearly studies of EU, the conclusion has been made that Slovakia has made an immense change in the state?s legislation when it comes to minorities and their fundamental rights, but that changes need to be made in attitudes as well.
I Have a Dream...: En studie om ideologiföring
Due to the highly competitive and busy marketplace of today, companies are forced to take unforeseen measures in defending and developing their brands. Key elements like opinion leadership and lifestyle marketing are commonplace and aim to deliver values that are more difficult to define compared to quality, price, looks and usability. This paper aims to develop what should be considered most fundamental to all commercial branding. By investigating the ideologies that are the core of many successful companies, we hope to clarify the importance of communicating these ideologies. The topic is examined by method of quantitative analysis and the main purpose is to determine; what do the companies think of their ideologies, and how do their consumers recieve them? A secondary purpose is also to investigate whether different kinds of consumers recieve the ideologies in different ways..
Variationer i revisionsprocessen - påverkar externrevisorns individuella förutsättningar revisionen?
The purpose of this paper has been to examine the question whether accountants differ in their auditing depending on their individual characteristics. We have summarized our own theory based on previous research and our own ideas. To conduct this purpose we used a deductive method. Our findings from the study show that we cannot exclude the possibility that accountants vary in their auditing depending on their individual characteristics. The answering frequency to our survey was only 47 %, and this may have affected the outcome of our research.
Modell och analysverktyg för beräkningav frekvensförlopp
The power system modelled in this thesis work has been developed for simulationwhen e.g. the production in some part of the power system is changed. The powersystem has been modelled according to the swing mass of the system, the frequencydependency of the load and the turbine governor. The model determines the systemfrequency, the period of regulation and the power exchange between the differentsubsystems in the Nordic synchronized system.In this model the system frequency is assumed to be the same in all different parts ofthe power system and the voltage conditions in the power system are neglected. Forthat reason power swings does not occur between different subsystems in the powersystem, which usually occur as a result of the swinging connection between thetransmissions line.
Optimering av distorsionseffekt med hjälp av Fourieranalys
In music performers and music-making are oftenused different distortion effects to give the desiredcharacter on the individual sound sources andinstruments. These have different names (fuzz,distortion, overdrive) depending on the character. Tocarry out this work, an extensive literature study ofthe circuit diagrams of a large number of the classicdistortion circuits implemented. In this work, adistortion effect of the character fuzz was createdfrom several other existing effects. MeasurementsFFT, frequency response have been conducted tovalidate the desired results along the given problem.The finished effect was named Instant Carlos and aprototype was manufactured.
Malmmineralogisk undersökning av Pb-, Zn-, Cu- och Ag-förande kvartsgångar i Värmskogsområdet, mellersta Värmland
AbstractPolymetallic (Pb-Zn-Cu-Ag-Au-Sb-As-Bi-Cd-Te-Se-Ge?) quartz veins occur in an area from Eidsvoll in southeastern Norway to west of LakeVänern in southwestern Sweden. They most likely formed during the waning stage of the c. 1 Ga Sveconorwegian orogeny. In Värmskog parish, Värmland county, several mineralized quartz veins of different types are known.
Icke-farmakologiska åtgärder för att förebygga förstoppning hos äldre personer - En litteraturstudieNon-pharmalogical measures to prevent constipation for older people - A literature review
Bakgrund: Förstoppning är ett av de vanligaste symtomen från mag- och tarmkanalen och att drabbas av förstoppning kan vara en hemsk upplevelse. Tillståndet påverkar personen både fysiskt, mental, socialt och existentiellt, vilket leder till försämrad livskvalité. Syfte: Att beskriva vilka icke-farmakologiska åtgärder som finns för att förebygga förstoppning hos äldre personer över 65 år. Metod: Studien genomfördes som en allmän litteraturstudie där vetenskapliga artiklar söktes i databaser på Internet och manuellt i referenslistor. Åtta vetenskapliga artiklar inkluderades i studien och dessa analyserades och utformades till ett resultat.
Motiv, möjligheter och framgångsfaktorer med RFID på lastbärare : Införande på Brunskoggruppen AB
Gapet mellan större och mindre lokala aktörer på transportmarknaden ökar vilket leder till krav på kostnadseffektiva och differentierade verksamheter. Detta bidrar i allt högre grad till effektivisering och automatisering av verksamhetens processer. Ett problem för verksamheter i logistiska sammanhang kan vara att lastbärare försvinner i leveransflödet vilket kan vara både kostsamt och reducera kundnöjdheten. RFID, Radio Frequency Identification är en teknik som kan användas i logistikprocesser för att ge en ökad synlighet på både lager-och logistikaktiviteter i flödet från leverantör till kund. För att kunna driftsätta en sådan lösning och få tillgång till den tänkta nyttan bör de involverade aktörerna engageras i ett gemensamt system som kräver uppsättningen av en lämplig infrastruktur. Brunskoggruppen AB är ett mindre logistikföretag beläget i Ljungby som upplever ökade kostnader för förlorade lastbärare i leveransflödet och ett behov av effektivisering av informationsflödet gällande densamma.Syftet med denna studie var att genom litteraturstudier, intervjuer och inslag av aktionsforskning undersöka och ge ett exempel på hur Brunskoggruppen AB kan införa en automatiserad lösning för spårbarhet på lastbärare.
Implementering av Constant Fraction Detection vid avståndsmätning
This thesis is performed at Saab Bofors Dynamics in Karlskoga and investigates a technique for ranging with laser pulses. The investigated technique is called Constant Fraction Detection (CFD). Described briefly, the received laser pulse is split into two equal parts, where one part is delayed half the pulse width and inverted. This signal is added to the original pulse. The resulting curve has the shape of a laying S and the detection of the zero level is used to stop the time measurement.
Vegetarisk kost - om sjuksköterskors kunskaper. En empirisk studie.
The purpose of our study was to establish whether the knowledge about vegetarian diet was enough among nurses in order to practise professional nursing. We made an empirical study based on a questionnaire. Twenty-one registered nurses answered the questionnaire that consisted of mostly open questions. The result showed that almost everyone experienced that they gave dietcounselling and many nurses mentioned that dietcounselling was important. The majority of the nurses thought that they had enough knowledge to be able in order to deliver a fundamental dietcounselling but nobody considered that they knew much about vegetarian diet..

Den ekonomiska tillväxten : en redogörelse för pessimistiska och optimistiska synsätt
The economic growth we have experienced the last century is based on limited natural resources. Whether these resources will last for a further economic growth is widely debated. Pessimism and optimism have each been influential philosophies in debate whose opinions can be conceded as two opposing opinions. In this paper we have analyze these opinions from an economics perspective. To study this further, the construction and meaning of the pessimistic and optimistic arguments have been applied implicitly on the Leontief production function and the Solow growth model.
Barn med språkstörning interagerar med olika samtalspartners : En samtalsanalytisk studie
Language impairment affects the ability to communicate. Children with languageimpairment have difficulties in using language in interaction to various degrees, and the contributions of the conversational partner are of great importance. The use of languagein interaction can be analysed by means of conversation analysis. The purpose of thepresent study was to study interaction of a group of pre-school children with language impairment with four different conversational partners. These were a peer with languag eimpairment, a peer with typical language development, a pre-school teacher and a parent.
