Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.

Föreliggande arbete tar sin utgångspunkt i Försvarsmaktens befintliga förmåga att verka med pansarvärnsrobotar. Med syfte att undersöka om det eventuellt finns ett tomrum att fylla för pansarbrytande robotsystem och att jämföra befintligt system mot föregående och ge förslag på önskvärda förmågor. Ur historik, äldre studier, teknisk data från föregående system och intervjuer dras slutsatser som ligger till grund för värderingar av det existerande behovet. Resultatet visar att pansarvärnsrobot 57 har god möjlighet till att lösa given uppgift om systemet tillförs i större omfattning inom skytteförbanden. Miljön styr taktiken, taktiken styr nyttan vilket i sin tur genererar effekt med systemet.

Abstract The purpose of writing this thesis was to improve methods during requirements engineering phase. Usercentred system engineering has some problem areas, which are examined and verified to create a new guideline for developers. This guideline tends to make requirements engineering more effective and help developers create more concrete requirements. It is not uncommon that system development projects ends up with unsatisfied users or delay in deliveries. The reasons are different kinds of communication problems between users and developers during verification of requirements. There is a therapy model, called solution-focused therapy, used in family and individual therapy. The model focuses on solutions for the future instead of problems in the past.

Trycksår kan förekomma på alla typer av vårdavdelningar och tar lång tid att läka samt är en stor kostnad för samhället. Syftet med litteraturstudien var att undersöka åtgärder för trycksårsprevention. Metoden är baserad på en modifierad version av Forsberg & Wengströms modell för en systematisk litteraturstudie. Sökning i databaser PubMed och CINAHL utfördes och resultatet i litteraturstudien grundades på nio kvantitativa vetenskapliga artiklar. Författarna kunde identifiera olika preventionsåtgärder där framför allt evidensbaserade bedömningsinstrument som Modifierad Nortonskala och MNA-SF är viktiga att använda i trycksårsprevention, men även temperaturmätning, ?Continental anal plug? (CAP), god nutrition, aktivitet samt tryckreducerande underlag som fårskinn..

Project management has been a very popular way of conducting information system development in the past years. Among all major information system developing companies today, almost everyone work in some form of project management. Our objective with this study has been to find out if there are any problems that begin in the early part of the project. Problems that, if they aren?t solved directly, can become bigger problems later on in the project.

Sweden has one of the best elderly cares in Europe and the Swedish care work is also one of the best in terms of quality, compared to other European countries. In recent years, higher demands have been set on the care work and the number of privatizations of public services has increased. In 2009 a new law came into force, the Act on System of Choice (LOV) which increased individual?s right to a greater participation and a free choice in the selection of health and social care providers. This paper aims to highlight the impact of the law, system of choice.

The purpose of this study is to evaluate an existing user interface. The company in question has a web-based user interface (available through logging in via their website), but they are interested in making the process of using the interface more convenient and the interface more accessible, so that users without a background in computing can properly manage the interface. At the same time they want to apply additional functionalities in order create and to manage increased traffic on the company?s website. For this reason it is important to take into account the issues involved in human-computer interaction (HCI) as well as aspects of cognitive psychology in order to make the tool and the web interface more usable, more motivational, and therefore more efficient and professional.

Superior Canal Dehiscence Syndrome (SCDS) is a newly described syndrome with symptoms including sound- and pressure induced vertigo, conductive hyperacusis and autophony. SCDS is caused by absence of bone overlying the superior semicircular canal and can be surgically treated. As the syndrome and surgical technique is new, it is of importance to study possible postoperative outcomes..

Background: Diversified companies, for example audit firms, sometimes offer different kinds of products and services. Different key success factors can in the same company thereby evolve. Goal congruence has to be achieved in the business divisions as well as in the company as a whole even though each business segment might have to focus on different factors. Purpose: The purpose is to analyze if differences in technology and culture between the business divisions in diversified companies motivate a differentiated reward system. Method: The study has a case study approach.

The Swedish Welfare Act § 4 says that "Animals must be kept and cared for in a good environment for animals and in such a way that promotes their health and allow them to behave naturally." Pigs in the wild spend 80% of their waking hours walking around and rooting for food, eating and exploring their environment with its snout. Fattening pigs in commercial farms spend 80% lying doing nothing. A lactating sow is lying down most of her day, and only 10-20% of the body surface is in contact with the floor, so the pressure is high on these spots. Piglets lie down and paddle with their legs, with high liquid content in the tissues, several times an hour, to stimulate and massage the sow's udder. In the existing system, these individuals are held more often on floors that are anything but inviting to sleep on.

Floating housing is a concept gaining ground in Sweden. The dwellings are different in many ways from traditional homes, not only regarding flotation, but also several other technologies. The purpose of this thesis is to emphasize the qualities that exist in living on water. The ambition was to present a proposal for a floating residential area located in Jönköping, containing homes of varying sizes, and to present their technologies. In order to find inspiration and solutions studies have been made on existing floating homes in Stockholm and Kalmar, focusing on their technical and functional solutions.
