To maintain a high position accuracy in robots is essential in today’s industry. Because of different factors, as for example wear and tear, the robots may need to be recalibrated after a while to maintain their high precision. Today the calibration can be costly. The robot is often sent away to be calibrated and will therefore cause stoppages in production, and if the calibration is performed in-
This study explores the Open Access phenomenon from the perspective of the commercial scientific publishing industry. Open Access has been appropriated by commercial publishers, once sceptical opponents of the concept, as a means among others of distributing scholarly publications. The aim of this study is to highlight a possible explanation as to how this has come about by looking at the internal
The use of industrial robots in manufacturing often requires good calibration approaches and tools to obtain and maintain the desirable accuracy of the robot, for the robot to be able to execute a task in a satisfactory manner. For high-accuracy methods of calibration, it is necessary to first identify the robot’s stiffness parameters. This thesis will focus on a method that is based on a clamping
The recent shift towards energy-dense and nutrient-poor diets has led to an increase of diseases such as obesity, diabetes and cardio-vascular disease. Due to poverty, geographical remoteness and lack of cultivable land, Kiribati experiences a double burden of malnutrition with high levels of NCDs among adults, and undernourishment among children. Since mothers are generally responsible for choosi
Konkurrensen är hög på den alltmer homogeniserade retail-modebranschen vilket kräver att företagen differentierar sig gentemot sina konkurrenter. Företagen fokuserar ofta på att stärka sitt varumärke genom att försöka omvandla frontlinjepersonalen till fullgoda varumärkeambassadörer. Frontlinjepersonalen har det huvudsakliga ansvaret för kundens uppfattning av varumärket i servicemötet. Därför för
Psykisk ohälsa hos piloter och flygpersonal har fått ökad uppmärksamhet sedan flygkraschen i de franska alperna med Germanwings flight 9525 år 2015. Det har lett till en ökad diskussion och medvetenhet samt utformande av olika program för Pilot Peer Support initierade av management på flygbolag, samt oberoende av piloter själva genom exempelvis fackligt arbete. Metoden för studien baseras på kvaliMental illness among pilots and cabin crew has received increased attention since the crash in the French Alps with Germanwings flight 9525 in 2015. This has led to increased discussion, awareness and the shaping of programs for Pilot Peer Support, both initiated by management of airlines and independently by pilots themselves through for example union work. The method for the study is based on qu
JastAdd is a tool for generating programming language compilers. These compilers generally use more memory than other compilers for the same language. In this thesis we have categorized the memory use of two JastAdd-generated compilers, to identify opportunities to reduce their memory use. We present several optimizations for reducing the memory use of these compilers. These include changes to the
Denna studie syftar till att identifiera samt behandla de utmaningar den svenska sjukvården ställs inför när informationssystem som man tidigare driftat i traditionella serverhallar på eller i närheten av sjukhus i allt större utsträckning ersätts eller migreras till molnbaserade lösningar. Genom en kvalitativ metodik har vi genom semistrukturerade intervjuer samlat in data från respondenter som a
Syftet med denna uppsats är att undersöka hur kvaliteten av hållbarhetsrapportering enligt GRI påverkar lönsamheten hos stora företag. Legitimitetsteorin och intressentteorin har använts för att förklara varför företag upprättar hållbarhetsrapportering. Resultaten av studien uppvisar inga signifikanta samband mellan kvaliteten på hållbarhetsrapportering och lönsamhet.
Cloud computing is a new technology which has changed business and society drastically, making it possible to create products and communication aids that were previously unheard of. Without it, services such as Facebook or Google Apps would probably not exist as we know them today. This thesis explores how cloud computing affects the value propositions of e-businesses, using data collected from mu
Under de senaste decennierna har det skett en expansion av butikskedjor i Sverige. Mindre butikskedjor har börjat etablera sig på marknaden och expanderat till fler städer, dock har de fått konkurrens från större butikskedjor som har etablerat sig i Sverige på senare tid. Alla butikskedjor erbjuder en uppsjö av utbud med kampanjer och rabatter samt andra erbjudanden för att kunna locka konsumenter
High quality III-V semiconductors on silicon substrate can make for significant progress in gate electrostatics and optoelectronic devices. Indium antimonide with its inviting properties can play a key role to further facilitate devise integration. But the question is, is it possible to obtain high quality III-V semiconductors on low cost silicon and still be able to manufacture it at large scale?
En undersökning av synen på barn och barndom i filmbearbetningar av Lewis Carrolls böcker om Alice. Utvecklingen av gestaltningarna av protagonisten och antagonisten i Aliceberättelserna jämförs med utvecklingen av synen på barn och barndom sedan "Alice's Adventures in Wonderland" publicerades 1865. Studien syftar till att bredda och fördjupa kunskapsområdet kring utvecklingen av syn
Almost every organizations works with projects, since a project is a onetime task with a clear beginning and an end and have never be done before. It is hard to say that a specific project method will suit all projects. It is up to the project manager who leads the project to choose a project method and use this as a tool to get the project to be successful together with a project team. Some resea
This study revives a heavily debated relationship between government debt accumulation and economic growth. Although indebtedness levels stay high, current economic growth forecasts seem optimistic not only in the euro area but in other advanced countries, as well. 24 advanced OECD economies are investigated to understand if financial outcomes are detrimental to the real economic variables in the
This paper investigates whether immigration promotes bilateral trade within the European Union between 2008 and 2015. Results from an augmented gravity model indicate a positive linkage between bilateral migration and trade, results which are in line with prior findings in the field research. Notably, the pro-trade effect is slightly larger for the import sector and immigrants seem to facilitate t
China experienced a growing economy with a huge market and business potential and became the second biggest country in terms of GDP. However, because of the limitation of coherent business laws and government supervision, entering the Chinese market became a severe and complicated problem for different kinds of firms. Empirical papers show that networks, called guanxi in China make a primary contr
Software security has become an increasingly hot topic of debate during the last few years of cyberattacks, especially now that we are entering the era of Internet of Things. How does the developer of a product decide which software to include from a security perspective and is it possible to create a tool for software comparison that the developer could use for this purpose? The aim of this thesi
This bachelor thesis “Time to take back what was once ours and give the finger to the middle class’ – A netnographic study focusing on the Instagram account Klasshat and their relationship to the upswing of the second hand-phenomenon” studies the popularization of second hand clothes consumption through a class and fashion perspective. Even though the history of the second hand market is closely c
This paper examines the ambiguous property rights in China and if they affect the private sector development. The indicators for property rights include both broader property rights and intellectual property rights. The property rights theory offers a perspective as a fundamental component of a market economy to enable a growth of private enterprises. The incentives and constraints offered by the
