Flimmer, eller närmare bestämt temporal ljusmodulering (TLM), har återigen blivit ett problem i samband med införandet av LED-baserad belysningsteknik. TLM, dvs. variationer i ljusintensiteten över tiden, kan ha en negativ inverkan på människors hälsa och orsaka irritation, huvudvärk, ögonbesvär och migrän. Förutom det onödiga lidande som TLM orsakar för enskilda personer utgör de negativa konsekv
Popular Abstract in Swedish Under 1990-talet genomfördes en genomgripande reform av det svenska gymnasiet. Dels ersattes de tidigare gymnasielinjerna med treåriga program, som samtliga ger en grundläggande högskolebehörighet, dels flyttades ansvaret för utbildningens genomförande och ekonomi från staten till kommunerna. Ett kriterierelaterat betygssystem ersatte också det tidigare normrelaterade. The general confidence in equal opportunity and equivalent grades are crucial to the moral justification of the social stratification in the modern society, in which meritocracy holds a hegemonic status. In Sweden, a political aim has been that everybody should get upper secondary education, and the government has established a National Agency for Education to promote and control the quality in ed
There is a vast global market of information and communication technologies to be used for educational purposes (ICT4E), both inside and beyond formal schooling. Both the products on offer and the large bulk of academic literature and strategic documents concerned with ICT4E tend to look at these technologies as providing simple technical solutions to complex educational problems. Moreover, the ut
When designing control systems for real applications, it is important to first do testing in a simulated environment, to ensure adequate performance. This is especially important when designing control systems for applications that have high operation costs, e.g., submarines, since late errors in the development can be extremely costly. Saab develops steering systems for submarines. Prior to this
In a world where innovative solutions can emerge from anyone, anywhere at any time, it has become imperative for companies to learn how to take advantage of this widespread abundance of knowledge. One way, through which organizations can access this external expertise, is by hosting online communities that facilitates interactions with external stakeholders. The master’s thesis conducted by Brandt
Vid mikroskopi så tar man en bild av ljus som har passerat igenom ett prov. Ljusets styrka påverkas av provet och fångas på en kamera. Ett problem som uppstår är när man ska ta bilder av genomskinliga material, dessa påverkar ju inte ljusets styrka. Det finns flera lösningar på detta problem, en av dessa kommer beskrivas här och har undersökts närmare i exjobbet.} Ljus färdas olika snabbt igenom This thesis contains an examination of a method for quantitative phase imaging using lateral shearing interferometry. The focus is on how the degree of spatial coherence in the light source effect the image. The method is examined by first creating a simulation of the system, then looking at some analytical solutions for the interaction between some parameters, and finally conducting an experime

Närmare bestämt utreds förhållandet mellan EU-domstolens autonoma tolkning av bestämmelsen och de motiv som sägs ligga bakom den exklusiva behörigheThe essay deals with the meaning of the exclusive jurisdiction in proceedings concerning rights in rem in immovable property, according to article 24.1 of the Brussels I-regulation (recast) (regulation 1215/2012), and its relation to Swedish international private and procedural law. More specifically, the essay investigates the relationship between the autonomous interpretation of the provision, g
The aim of the study is to find a relation between the tip pressure produced by ram sounding and CPT in order to improve the possibilities of determining the shear strength of clay till. CPT is a pressure probe and mainly used to get a good picture of the statigraphy and the soil condition. CPT has shown to be useful regarding the evaluation of key parameters such as shear strengh and angle of fri
Artikel 1(1) i FN-stadgan ger uttryck för FN:s grundläggande syfte, att bevara den internationella fred- och säkerheten. Vidare föreskriver artikel 2(4) FN-stadgan att alla medlemsstater ska avhålla sig från bruk av, eller hot om, mellanstatligt våld. Dessa regleringar kompletteras av att stater enligt folkrätten tilldelas en omfattande suveränitet. Som utgångspunkt är stater således förbjudna attArticle 1(1) of the Charter of the United Nations states the main purpose of the United Nations, which is to maintain international peace and security. To achieve the purposes laid out in the Charter all states shall, according to article 2(4) of the Charter, refrain from the threat or use of force against the territorial integrity or political independence of any state, or in any other manner inc

Current advances in Deep Learning have shown significant improvements in common Machine Learning applications such as image, speech and text recognition. Specifically, in order to process time series, deep Neural Networks (NNs) with Long Short-Term Memory (LSTM) units are widely used in sequence recognition problems to store recent information and to use it for future predictions. The efficiency i
An ongoing trend the last couple of years has been the intense reporting of an increased amount of deliberate vehicle fires in Sweden. As the overall assumption in society is that the number of deliberate vehicle fires is steadily increasing, a statistic model trying to investigate this was made. In 1998, the share of deliberate car fires were estimated to 12%, the same number in 2015 was 38%, ind
Miljöproblemen har länge varit ett aktuellt och omtalat diskussionsämne som man aktivt jobbat för att begränsa och minska människans negativa klimatpåverkan med målsättningar samt nya lagar och krav. Byggsektorn står idag för en betydande del av Sveriges koldioxidutsläpp och för att ha möjlighet att uppnå de mål som finns i Parisavtalet krävs åtgärder i byggbranschen. Klimatneutralitet är ett relaThe environmental problems have for a long time been a current and highly spoken topic of discussion which one has actively worked to limit and reduce the human's negative climate impact with agreements, laws and requirements. Today the constructions sector stands for a significant part of Sweden's carbon dioxide emissions and to be able to achieve the goals in the Paris Agreement, measure
Nearly 40 percent of overall energy usage in the European Union is used by buildings and 85 percent of that is for heating and cooling them[4]. This massive amount of energy is thought to be able to be lowered by introducing smarter control of the building systems. Technology to do this is continuously being developed and improved. The newest analysis system developed by Schneider Electric uses cl

Wind energy production is a section that became bigger and bigger thanks to the interests in finding new ways to produce energy that do not involve fossil fuels because of environment concerns, because of their costs and because of their limited amount. Even though wind energy was exploited also in the past, for example in wind mills, it is with wind turbines that all the problems affecting these
Since the early 1980’s and up until today many organizations have realized the importance of paying more and more attention to the effective strategic planning of the information systems resources. There are several reasons for this that where recognized by Pyburn (1983), one was the high speed of technological progress both in regards to IT and Telecoms facilities. Another key factor, which is ve
