The increasing complexity in the development of a configurable real-time system has emerged new principles of software techniques, such as aspect-oriented software development and component-based software development. These techniques allow encapsulation of the system's crosscutting concerns and increase the modularity of the software. The properties of a component that influences the systems performance or semantics are specified separately in entities called aspects, while basic functionality of the property still remains in the component. When building a real-time system, different sets of configurations of aspects and components can be combined, resulting in different configurations of the system. The temporal behavior of the system changes and a way to ensure the predictability of the system is needed.

I föreliggande studie undersöks hur användare upplever användbarheten i ett säkerhetskritiskt system ? Luftfartsverkets flygledningssystem SIGMA. Utifrån litteraturstudier definieras begreppen användbarhet och säkerhetskritiska system. Empirin utgörs av intervjuer med användare av SIGMA-systemet. Studien visade att användarna upplever att systemet i väsentliga delar har bra användbarhet, vilket utifrån litteraturstudier, intervjuer och efterföljande analys främst tycks bero på att systemet arbetats fram med stor användarmedverkan och att det var utarbetat specifikt för arbetsplatsen.

Denna uppsats behandlar fenomenet chefslöst medarbetarskap. Ett teoretiskt område som går att relatera till självstyrande team, delat ledarskap och informellt ledarskap. Alla är företeelser som kan kopplas till platta organisationer, vilket är en organisationsform som under 2000-talet blivit allt vanligare. Detta väckte ett intresse hos undersökningsgruppen där frågor angående vilka effekter ett chefslöst medarbetarskap kan ha i en organisation uppstod. I uppsatsen redogör därför författarna, med hjälp av fallföretaget Fresh AB, för dessa effekter.Undersökningen i fallföretaget genomfördes med fem fokusgrupper med deltagare från olika delar och team i fallföretaget.

The purpose of this study is to achieve an understanding of how a CE- marking process is conducted and to identify the relevant factors that must be considered in such a process. We have conducted our study at Lo?vhults Svets & Smide AB (Lo?vhults) in Skruv, Sma?land Sweden, which are manufacturing brackets for small covering constructions.To understand how a CE-marking process is conducted several documents and provisions have been reviewed to achieve a basic understanding and insight of the subject. It thus led to that guideline ETAG 015 were studied and the factors to be considered in the CE-marking of brackets were identified. Together with Jan-A?ke Johansson at Lo?vhults we agreed on four different brackets to investigate for a potential CE-marking.

This master thesis work was done at Saab Underwater Systems AB, a company at the cutting edge of underwater technology. Here torpedoes and other underwater vehicles are developed and manufactured. The major customers are navies of different countries, mostly the Swedish navy. The aim of this master thesis is to develop, construct and evaluate an automatic Trim System for Unmanned Underwater Vehicles. The task of the system is to change the position of the centre of mass and the vehicle?s total mass or volume.

Elever ska enligt kursplanerna i teknik få förståelse för de tekniska system de möter i sitt dagliga liv. Genom att eleverna får kunskap om teknik i allmänhet och tekniska system i synnerhet får de möjlighet att påverka sina liv som medborgare i en demokrati. I litteraturen saknas idag studier om elevers uppfattningar om tekniska system. Syftet med detta examensarbete är därför att studera vilka vardagsuppfattningar elever har om de tekniska system de möter i vardagen. Studien utgår från systemteori vilken ger en möjlighet att utnyttja det gemensamma mönster som kännetecknar analys av system.

Syfte: Syftet är att få ökad kunskap om förändring i hälsa och sjukskrivning hos individer/patienter med stressrelaterad ohälsa som bedömts av ett multidisciplinärt team. Ohälsa avser depression, ångest och utmattningssymptom samt hälsorelaterad livskvalitetUndersökt grupp: Personal med stressrelaterade problem anställd inom Västra Götalandsregionen och Försäkringskassan i Västra Götalands Län.Metoder: Jämförelse av sjukskrivningsgrad och hälsoläge vid, och 6 månader efter bedömning av ett multidisciplinärt team inriktat på stress och utmattningssymptom. Instrumenten för att mäta förändring i psykisk ohälsa är 3 självskattningsformulär, Hospital Anxiety and Depression scale; HAD, Psychologic General Well-Being; PGWB och Shirom-Melamed Burnot Questionaire; SMBQ.Självskattningsformuläret fylldes i innan första kontakten med företagssköterskan i teamet samt vid uppföljning efter 6 månader.Uppföljningen bestod i en kort telefonintervju med frågor om sjukskrivningsgrad och hälsoläget.Resultat: Sjukskrivningsgraden minskade hos 45 %, endast en hade ökat. Hälsoläget förbättrades hos mer än 50 % 6 månader efter mötet med teametAntalet personer med depression enligt HAD hade minskat från fem till en och de med ångest enligt HAD från åtta till tre.Tolv personer har minskat och fem har ökat sitt poängmedelvärde på SMBQ Globalskalan.Välbefinnandet enligt PGWB-skalan ökade. Antalet med poäng över 100 ökade från tre till åtta och de med poäng 95 eller lägre minskade från fjorton till tio.Slutsats.

Computer based information systems play an important role in modern military combat vehicles. The crew needs to be able to quickly get information about both the vehicle and its outer surroundings in order to quickly make the correct decisions. In this report, we describe the development of a prototype new information system for the BvS10 vehicle, manufactured by BAE System Hägglunds AB in Örnsköldsvik.An important aspect of the system is the time it takes from the point that the information is generated by the vehicle sensors until it is presented to the user. The system must be able to ensure that it never displays information that is out of date. Thus, it is important to create a layer and component based architecture for the solution, making it possible to control, in detail, the information?s age as it moves through the system.

ABSTRACT (english)Introduction: The possibility to transplant an organ is an important part of the health care system, which demands great resources and a well functioning organization with a level of high competence. The work with organ donation is complex and brings forward a great amount of different emotions for the operation room nurse. Aim: The aim with the study is to illustrate the operating room nurses experience when the organ donor is brain dead. Method: Data collection has been performed with semi-structured interviews, which have been interpreted by qualitative manifest analysis. The design of the study is pilot towards a study in full scale.

When using the digital halftone proofing systems, a closer print match can be achieved compared to what earlier couldbe done with the analogue proofing systems. These proofing systems possibilities to produce accurate print match canas well lead to producing bad print matches as several print related parameters can be adjusted manually in the systemby the user. Therefore, more advanced knowledge in graphic arts technology is required by the user of the system.The prepress company Colorcraft AB wishes to control that their color proofs always have the right quality. This projectwas started with the purpose to find a quality control metod for Colorcraft´s digital halftone proofing system(Kodak Approval XP4).Using a software who supports spectral measuring combined with a spectrophotometer and a control bar, a qualitycontrol system was assembled. This system detects variations that lies out of the proofing system´s natural deviation.The prerequisite for this quality control system is that the tolerances are defined with consideration taken to the proofingsystems natural deviations.

An important task for project managers in multi-project environments is to effectively choose the right people to the project team. For organizations, it means being able to prioritize and plan human resources among the various projects running in parallel. The purpose of this paper is to describe how a project manager in multi-project environments looks at the allocation of people in their projects. We did our research through literature reviews and interviews with seven project managers.The research shows that the studied organizations highlight both the expertise and the personal factors in an election. They do not use any specific personality test to identify their staff.

Vårt syfte med denna studie är att utifrån en socialpsykologisk ansats ta del av elevhälsovårdens och stödverksamhetens arbete respektive samarbete på en gymnasieskola i en medelstor stad. Med hjälp av kvalitativ metod har vi utfört sex enskilda intervjuer, en parintervju samt ett experiment. Vi har använt oss av följande socialpsykologiska teorier: Gruppsykologi (Svedberg, 2007), Det potentiella rummet (Winnicott, 1993), Ungdomstidens kriser (Cullberg, 2006), Den konkreta och abstrakta socialiteten (Asplund, 1987), Benämnandets kraft (Crafoord, 2005), Emotionsteori (Scheff, 1990). Genom dessa teorier har vi försökt belysa svårigheter med, och ge en förståelse kring, hur elevens situation i skolmiljön ser ut samt hur arbetet inom, respektive samarbetet mellan, elevhälsovård och stödverksamhet mot en god elevhälsa ter sig. Vi har i föreliggande studie upptäckt att vissa typer av problem respektive svårigheter hos eleven uppmärksammas medan andra glöms bort.

Diagnosis means detection and isolation of faults. A model based diagnosis system is built on a mathematical model of the system. The difficulty when constructing the diagnosis system depends om how the model is formulated. In this report, a method is described that rewrites the model on such a form that the construction of the diagnosis algoritm is easy. The model is transformed by two state space transformations and the result will be a system on state space form where one part of the system becomes easy to supervise.

In a time where information overload is a fact, well formulated messages is required and communication is a big contributing element for building strong brands. In the north of Sweden, Norrmejerier is one of the big actors with dominance on the dairy factor market. Through making milk products that lands in the consumers refridgerators, they are not only working for economical interest but also for improving the nature of the north of Sweden. Through visual communication, Norrmejerier shows the consumers a beneficial view of the north of Sweden which corresponds to the populations own impression of their part of the country. This contributes to a feeling of belonging that makes strong and loyal consuments. The feeling of belonging is also reflected in Norrmejeriers commercial movies, that uses the consumers conscience to make costumers. By two group interviews and a semiotic analysis of Norrmejeriers commercial movies, this study aims to examine how Norrmejerier uses qualities of the north of Sweden when building their brand.

The upper secondary school 2011 (Gy 2011) was a reform which created large changes in the Swedish educational system. One of the major changes was the requirement of certification for sport schools. Schools in Sweden have historically used sports in their marketing, this opportunity was impaired by the reform. This thesis aims to investigate how brands are applied on webpages of sport schools that are certified in football and/or cross-country skiing. Content analysis was used as method of data collection.
