Internet and information technology today has a rather obvious role in the activities of companies and organizations. All cash transactions within and between companies is digitized, communication within the company is done via e-mail, sales and marketing is done largely with marketing and ads on the Internet. This has resulted in economic benefits for companies and organizations, and facilitated the work for them. However, this has also led to new threats have emerged. Companies and organizations is well aware that there are numerous threats that comes with using the Internet and Information Technologies but exactly what those threats are for a mid-sized company in Sweden is not clarified anywhere.

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.

I Sverige har förekomsten av klamydia ökat hos ungdomarna sedan 1997 och fortsatt stiga under 2000-talet. Den sexuella aktiviteten har förändrats till att ha fler tillfälliga partners och att skydda sig med kondom är inte alltid så självklart för de unga. Det kognitiva- och socioemotionella ssteme i hjärnan är inte färdigutvecklat hos tonåringarna vilket kan leda till spontana beslut och riskfyllt beteende. Syftet för denna litteraturstudie var att beskriva skolhälsovårdens hälsofrämjande omvårdnadsåtgärder för att påverka ungdomars sexuella risktagande. Event History Calendars, en metod för det individuella hälsosamtalet visade efter en månads postintervention en minskning av det sexuella riskbeteendet.

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.

Probiotika, nyttiga bakterier som är välgörande för människan, förekommer allt mer i olika produkter riktade till små barn ? alltifrån droppar och kapslar till modersmjölksersättningar och grötar. Inom barnhälsovården saknar barnsjuksköterskan/ distriktssköterskan vägledning och riktlinjer angående probiotika i små barns kost. Syftet med litteraturstudien var att undersöka evidens angående probiotikas hälsoeffekter i preventivt syfte på friska små barn. Metoden var en litteraturstudie baserad på 20 vetenskapliga artiklar.

Förekomsten av brott är ett stort problem i vårt samhälle och har stor inverkan på de enkla beslut som tas i vår vardag, exempelvis på valet av område att bosätta sig i. Historiskt sett har ansvaret för att förebygga brottslighet legat hos polisen och de enskilda hushållen men de kan inte allena lösa problemen med brottslighet, och följaktligen blir en bredare strategi för brottsförebyggande arbete nödvändig. Ett sätt att utforma säkerheten är genom arkitektur och kallas för Crime Prevention through Environmental Design (CPTED). Perspektivet avser att minska både möjligheter och rädslan för brott genom att utnyttja de möjligheter som finns att öka överblickbarheten, att ta vara på framtoningen av ett område och att stärka den territoriella känslan hos invånare i ett bostadsområde.Grunden för den teoretiska ramen kommer från artikeln Towards an Economic approach to Crime and Prevention (2002), och använder sig av de fyra begreppen som utvecklades av Clark och Homel (ökad ansträngning, en ökad risk, minska belöningar och minimera antalet potentiella ursäkter). Det finns mängder av litteratur som behandlar ett ekonomiskt angreppssätt på brottslighet, men det finns emellertid få ekonomiska bidrag vad gäller att förebygga brott, och ännu färre inom området för att utforma brottsförebyggande arkitektur.

Unit testing is a type of testing technique which is becoming quite fashionable to the developers and companies that are in the business of creating and managing software. Alas there are seldom any concrete data to support the positive claims of the authors in unit testing methodology books. These claims are instead based on empirical studies and the experience of the authors. The problem that arises from this situation is that it becomes problematic for managers and also the developers themselves to convince both customers and their own management to use this type of testing as there is no exact return of investment model. This essay examines this problem from two points, the first point is from the literature itself and interviews conducted with a number of developers at a software company located in Umea, Sweden.

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.

This examination report is a part of a program for Industrial organisation and Economics with specialization in Logistics and Management at Jönköping University. The report contains an analysis of the internal material handling at Kongsberg Automotive, and also an improvement proposal for a new material handling system.The aim with the report is to find a better material handling system and also make an analyse of the existing system. The goal is to shorten the distance for the operators when they order material, and also to increase the productivity.The investigation methods for the report have for the most part consisted of observations and interviews of key-persons who daily work in the production. During some time the actual material handling-system has been observed and some shortcomings have been discovered, and these are also discussed in the report.The shortcomings that have been discovered are for once the indistinct signal that should signal need of material in the production. Some other activities have also been discovered that does not bring any value into the final products.

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.

The purpose of this thesis work was to develop an automatic fault detection system for surveillance of bearing temperature in hydropower turbines. The parameters used except the bearing temperature were cooling water temperature and cooling water flow. A simple static model based on data sampled every minute was developed to estimate the bearing temperature. Then a detector for detection of change in bearing temperature based on the CUSUM-algorithm was designed. Since the amount of data was very small the developed model was too uncertain to be used in a working system.The designed fault detection system showed to work well for the available data.

We have carried out a study of a classification system for the Swedish collection at The Royal Library in Stockholm from 1887. It was printed in 50 copies. The constructor, Bernhard Lundstedt, and his colleagues used it as guidance in lack of a catalogue. We regard it a local classification system. Little research has been done on old classification systems, but Francis Miksa points out the importance of examining them.
