The information stored on theese computers can be very easy to retrieve if you have the will and the skill to do it. Very few people have any knowledge how to protect themselves from theese threats..
Del projekt inom ClampCal - Utvärdering av mätmetoder för temperatur, viskositet och densitet samt röregenskaper
The dissertation were performed on SP, Technical Institute of Sweden.
The dissertation were carried out on the measurement technical department, this dissertation is a part of a bigger project, project ClampCal.
One of SP?s returning assignments are flow-measurement. When flow-measurement is performed, the flow has to be stopped so that a meter can be installed in the pipes where measurement is going to take place. At every stop there is time delay in the flow which causes the customers to loose money. This is why SP wanted to find a better solution so that measurement can be done without any stops in the flow.
Usage of a so-called Clamp-on meter was considered, but since the measurement uncertainty is too large it takes some investigation on the parts where the largest uncertainties occur and thus find a solution that can diminish the uncertainty as much as possible.
The parts that were considered to have an opportunity to reduce measurement uncertainties were the fluid temperature, its characteristics and the pipe geometry and its characteristics.
For the fluid temperature a Pt100-sensor with four different radii for various pipes was used.

A vulnerable group in society is people with ASD (autism spectrum disorders) or autism. This group seems to increase, mainly due to genetic factors but also environmental problems. Medical research has accelerated in the U.S. and Europe. The biggest problem for people with disabilities is the inability to communicate, both verbally and socially.
Integration av PLM och CAD i komplex produktutveckling : En utredning av Scanias framtida systemmiljö för produktdatahantering
In today's producing companies, there is a high demand on early integrated productdevelopment. One way to facilitate communication between departments and collaborationbetween people and thereby enable early sharing of product information within the companyis to use PLM, Product Lifecycle Management.The CAD environment at Scania is at the moment being upgraded from Catia v4 to Catiav5. In this stage it is important that also the interacting computer systems in Scania?s PLMenvironment are adjusted and in the future join the development. Scania has an idea of howthese systems will be developed as the transition from Catia v4 to Catia v5 is being carriedout.
Bevarande av webbplatser : En kartläggning bland statliga myndigheter i Sverige
The purpose of this thesis was to investigate if Swedish agencies preserve their websites according to the Swedish archival legislations and guidelines. As a theory the OAIS Reference Model (Open Archival Information System, developed by US Consultative Committee for Space Data Systems, CCSDS) has been used as a model to show how important it is to develop strategies for public digital information which has to be preserved for long term. The ingest function in the OAIS Reference Model demands that files are prepared for long term preservation and requires that the digital information fulfils established technical requirements.In the study the Swedish National Archive and their advices about preserving websites to archivists on the Swedish agencies are being studied. To control if the agencies meet the requirements for their management and preservation of their websites a survey was sent out to investigate if Swedish agencies preserve their websites. According to the survey result, 84 of 113 agencies preserve their websites in some way. If the technical requirements really was met could not be verified in this thesis, the results was relied on the responses from the authorities.
The digital dark age? Bevarande av elektroniskt material i Sverige
The first law in Sweden containing an act of legal deposit is from 1661. Since then the printing-houses are supposed to deliver all printed material to the Royal Library and other recipient libraries. Today, more and more information is solely published electronically. This material is not yet included in the law of legal deposit. In a similar way as our printed cultural heritage is saved for posterity our electronic cultural heritage has to be saved.
Miljöklassningssystem : Skillnader mellan Miljöklassad Byggnad och LEED samt dess påverkan på fastighetsvärdet
A uniform environmental rating system for green buildings is demanded in today's society, where the requirements of the energy consumption for real estate are increasing. There are several different systems around the world used to rate buildings, all with different assessment criteria and starting points, which make it difficult to compare environmental rated buildings with each other.The purpose of this paper is to acquire knowledge about the differences between the Swedish environmental rating system Miljöklassad Byggnad and the American LEED, to discover which system is most advantageous. We also examine whether environmental rating affect the value of a property.Miljöklassad Byggnad is relatively simple structured, which makes it possible for private individuals to rate their property. LEED is better structured on the other hand in the case of environmental classification of commercial properties, because there are manuals for among others hospitals, schools and retail. The rating system for Miljöklassad Byggnad is good since the system seeks to fix the number of errors and deficiencies as soon as possible.

Byggnadsarbetarens syn på att bli involverad i projekteringen : En intervjustudie i byggprojekt
Title Becoming involved in the planning process - from the construction workers perspective.University/Institution Halmstad UniversityKeywordsEmpowerment through participation, construction workers involvement in decision making in the planning process, knowledge management and communication in the planning process, partnering, human resource managementAimThe aim of this bachelor thesis is to provide knowledge and examine how construction workers perceive involvement in the planning process of partnering projects, what they can contribute and what they get out of the planning process.Methodology The study was conducted with a qualitative approach in the form of semi-structured interviews. The interview studie consist of 10 interviews with construction workers who are specially educated in participating in the planning process at the company ByggDialog AB.ConclusionAll respondents are positive to be involved in the planning process. The main advantages they can see is that they are able to influence technical solutions and methods that will be used later on in the production. Therefore it is important to consider when construction workers should be involved in the planning process so that they get the chance to influence in this decisions.When it comes to the decision making the construction workers should be involved in the decisions that are related to their tasks in the production such as technical solutions, choice of methods and materials. Their main duties and working hours should be in the production.Involvement in planning does not automatically mean that the construction workers are involved in the decision making, it is up to them how much they participate.
Gränser : En studie av den estetisk-praktiska miljöns pedagogisk-terapeutiska grundegenskaper utgående från två verksamheter: Hagastiftelsens verkstäder och Kristofferskolans bokbinderi
Borderlands. A study of the aesthetic-practical environment, its pedagogical and therapeutical properties based on the outline of two practices/institutions: the workshops at Hagastiftelsen and the bookbindery at the Kristofferschool. The perspective on education, pedagogy and therapy taken is an existential one where the main aims of an educational-therapeutic intervention is to support biographical development and integrity. In the process action research in my own bookbinding workshop as well as hermeneutic research at the workshops at Hagastiftelsen where adults with autism and other neuropsychological disorders work have been the sources of primary empirical data. Secondary sources are patient-histories written by Oliver Sacks as well as autobiographical narratives of some adults with autism.
Val av fönster - En Multikriterieanalys
Fönster blir idag en allt viktigare del av en byggnads klimatskärm. Det ställs därför krav på olika funktioner vilka måste uppfyllas oberoende av fönstertyp. Då glas blir vanligare i moderna konstruktioner ställs det högre krav på värmeisolerande förmåga. Cirka 35 % av en byggnads värmeförluster sker genom fönster. Detta ställer krav på tillämpning av energieffektiva fönster vid ny- och ombyggnad. Underhåll av fönsterkonstruktionerna är en oundviklig detalj och måste ske någon gång under en byggnads livslängd.

Phosphate is a used as a surface treatment method which is used for various purposes in the industry. In this case, phosphate coated wire is used in the processes to achieve a desirable outcome. The reason to why phosphate coated wire is used in the production process is because phosphate acts as an accumulator, where it stabilizes the lubricant on the surface of the wire. Lubrication is important because it plays a major role in the roll quality and characterizes important benefits regarding the outcome.Currently, SKF has to wash away all phosphates residues after extrusion process in an operation called tumbling. The main reason for this is simply because the surface has to be completely free from lubricants and coatings till the next step of process.
