The main purpose of this thesis is to present a Cultural-Historical Activity Theory (CHAT) based analysis of the activities conducted by and with visually impaired users supported by audio-haptic technology.This thesis covers several studies conducted in two projects. The studies evaluate the use of audio-haptic technologies to support and/or mediate the activities of people with visual impairment

Klimatförändringen medför att allt mer frekventa och kraftiga skyfall belastar den ständigt växande staden. Urbaniseringen tillsammans med förtätningen av stadsmiljöer har lett till att sådana regn får allt större konsekvenser. Detta beror på den ökade andelen hårdgjorda ytor som hindrar nederbörd från att naturligt infiltrera. Istället bildas större volymer ytavrinning som måste ledas bort för atDue to climate change more extreme precipitation is expected to strike the constantly growing cities around the world. Urbanization along with densification of urban areas magnifies the impact of heavy rainfall. These two processes have increased the amount of hard surfaces that prevent precipitation to naturally infiltrate, and therefore result in larger amount of surface runoff that must be dive

Lake sediments have lately been explored as a 10Be archive, complementing previous research on ice cores and marine sediments. 10Be is an important proxy as it can be used to study past solar activity, a factor which affects the climate. Where other methods studying solar activity only cover a brief period of history, 10Be has the potential to go further back in time. The concentrations of 10Be st

Untreated asthma limits the ability to live an active life, still many asthmatics does not have the level of control over their asthma as they could have. In addition, about 50% of the asthmatics use their inhaler incorrectly, which affects the result of the medicine negative. The asthma inhaler is central in an asthmatics living and has great potential for de- velopment towards a modern asthma mo

Flyktingar, alternativt skyddsbehövande och övrigt skyddsbehövande har rätt till uppehållstillstånd då dem har asylskäl i den svenska rätten. Uppehållstillstånd kan även beviljas när det föreligger synnerligen ömmande omständigheter. Ensamkommande flyktingbarn som flyr från krig eller förföljelse i hemlandet möts i Sverige av en asylprocess där åldern är viktig för prövningen av uppehållstillståndRefugees, persons eligible for subsidiary protection and persons otherwise in need of protection have the right to residence permit when they have grounds for asylum in the Swedish law. A residence permit may also be granted for an asylum seeker with exceptionally distressing circumstances. Unaccompanied children who are fleeing war or persecution in the native country meet in Sweden an asylum pro

Issue of Study: The case company, Metius, has difficulties in meeting its customers’ demands for delivery reliability due to issues in the final assembly process. A leading management control system linked to the company’s final assembly could allow the production management to act proactively and avoid more dissatisfied customers due to poor delivery reliability. Relevant literature gives little

The aim of the thesis is to investigate the impact of mediatization on the harshen Swedish terror law with the intention to explicate an interaction between media and politics. The analysis applies a deductive approach based on critical security studies and theories of mediatization which will adhere process-tracking as a main strategy. The process-tracking will not show any correlation since the

This thesis analyse different understanding of the world how this leads to different actions with real consequences for people. In a public policy chain from the government of Sweden down to the field in Burkina Faso, civil servants have been interviewed in order to identify changes in discourses and what they may potentially mean. The use of qualitative data gives a deeper understanding of how in

A multi-antenna base station (BS) can spatially multiplex a few terminals over the same bandwidth, a technique known as multi-user, multiple-input multiple-output (MU-MIMO). A new idea in cellular MU-MIMO is the use of a large excess of BS antennas to serve several single-antenna terminals simultaneously. This so-called "massive MIMO" promises attractive gains in spectral efficiency with

Lek är något som skall vara något positivt, oskyldigt och tillföra glädje för barnen. På förskolor spenderar barnen den mesta av sin vakna tid, där de leker, äter och sover middag. Det är en plats där barnen skall känna sig trygga. Få vet att det faktiskt finns skadliga kemikalier i textiler, köksredskap och till och med i leksaker som en så känslig grupp som barn kommer i kontakt med. Att skadlig

Livsmedel är någonting som alla individer konsumerar flera gånger om dagen utan att reflektera över om det man äter kan påverka ens mående och välbefinnande. Det som konsumenten förväntar sig av livsmedlet är att det inte är förorenat eller innehåller mikrobiella, kemiska eller fysikaliska faror som göra en sjuk. De frågor som man som konsument kan ställa sig är: Hur vet livsmedelsföretagen att deThe English title of this master thesis project is ”Risk assessment, hazard analysis and HACCP plan during production of fruit- and berry based products”. As the title refers to, this projects is divided into two part. The first one is the risk assessment of a company’s raw material for their production. The second part is a Hazard Analysis Critical Control Point (HACCP) method that is used to eva

The purpose of this study is to examine the perceptions of various hierarchical levels regarding AI integration into the innovation process within a KIF and examine its influence on the design and usage of MCS. By synthesizing insights into the relationship between AI integration and MCS, this research contributes valuable knowledge to academic discourse and practical implementation strategies, en

Kan mjölk skydda mot gropfrätning på processutrustning av rostfritt stål och hur kan man testa det? Tetra Pak säljer högspecialiserad processutrustning till livsmedelsproducenter och utrustningen är ofta tillverkad av rostfritt stål. Stålet motstår många typer av rost, men gropfrätning är en typ av korrosion som påverkar stålet vid framför allt höga temperaturer och höga salthalter. Dessa förutsäThis master’s thesis is written for Tetra Pak with the aim to investigate if pitting corrosion inhibition can be detected for Stainless Steel 316L in contact with dairy products in an experimental setup. The aim was also to continue developing a corrosion test method to facilitate for material selection of food pro- cessing equipment in order to reduce the extent of detrimental pitting corrosion.

Mänskliga aktiviteter påverkar den biologiska mångfalden genom en mängd olika aktiviteter som ofta leder till att ekosystem utarmas. Detta leder i förlängningen till stora samhällsekonomiska förluster. Det nuvarande svenska rättsliga systemet för bevarande av biologisk mångfald fokuserar på att bevara och skydda arter som är hotade och specifika områden där dessa lever. Jag ifrågasätter utgångspunHuman activities affect biological diversity in a multitude of ways,often leading to a disruption of ecosystems. In extension this results in large economic losses for the society. The present Swedish system for preservation of biodiversity focuses on conservation of species and the specific habitats of these. I want to challenge the basic premise that biodiversity is best sustained through the pr

Background: In today’s globalized world, many producing companies depend on large supplier networks. Supplier relations require maintenance and a tool for that is supplier auditing. ABB is a leader in power and automation technologies that enable industrial customers to improve performance while lowering environmental impact. ABB business division Process Automation (PA) and business unit Control

The automotive industry is currently witnessing a standard battle between the emerging propulsion technologies and the internal combustion engine. Almost all efforts, whether they are initiated by governments or established players of the automotive industry, have been deployed on a small-scale basis. However, an ambitious attempt is currently being made by the venture-backed company Better Place,
