Z39.50 is a standard protocol designed to create an interface between diverse computer databases for diverse information needs. Since it has to be adjustable it is also complex and demands a certain degree of expertise when being set. However, the aim of this paper is not to make a theoretical description but to examine certain conditions in practice. From the perspective of Swedish research libraries two principal hypotheses are examined: 1) the implementation of a given technology (Z39.50) is primarily influenced by social circumstances, and 2) the way in which the technology is implemented will bias the results of information retrieval. For this examination we need a framework of theories concerning the relationship between technological development and society, organisational theories and database theories.

In the spring of 2009 Silva Sweden AB was contacted for a collaboration within the scope of a MasterThesis project. The company had discussed the possibility to develop a device that monitors usermovement during different types of exercise. The objective of this Master Thesis has therefore been todevelop and design a multi training device that records the user?s physical performance during severalactivities. The purpose of the thesis project has been to use scientific methods for product development inorder to design a multi device that supplements Silva?s range of products.The project followed a product development process divided into four phases; Market Analysis, ConceptCreation, Concept Development and Construction.

As a part of Göteborg Energi?s work towards a smarter electric grid, the company has chosen to investigate the possibilities of automation in their middle voltage grid. In Europe, there are example cases where these technologies already are installed which many articles on the CIRED conference 2011 proved. Netcontrol Oy in Finland has, together with Tekla, created an automated SCADA system that Vattenfall in Finland today uses. The grid mainly consists of 10 kV open loop fed city grid and this automation is mainly designed for this type of grid.

The objective of this study is to investigate a new pedagogical material called 4DFrame, how it is experienced by informants and how suitable it is in education - in particular mathematics. Socioculturalperspective has a central role in this study when students are given opportunities for linguistic and social interaction during the experiment with the new pedagogical material. The methodology for this study has been visits, interviews, and observations. The study reveals that there are different views on the didactic potential for mathematics of the new teaching material, though no conclusions can be drawn regarding whether this material is more or less suitable in teaching since no research have been found that compares this with other pedagogical materials. Both national and international studies show the need to find alternative and better ways to make mathematic education meaningful.

Sweden has a natural gas grid extending along the west coast, from Trelleborg to Stenungsund. There are also several smaller local networks where a planned natural gas pipeline from Skutskär to Hofors prompted the need for a comprehensive study. This study examines the linkages that exist in terms of technology and market of natural gas and biogas in Sweden. Sweden has set high targets for the future with ambition to become independent of coal and oil as energy sources. Since 1985, a part of the solution has been import of Danish natural gas.

This study is predominantly qualitative. It is also descriptive to a large extent and notoriented towards hypothesis-testing. The study aims at studying what has influenceddigitization of old Swedish dramatical works through the Dramawebben projekt, whilefocusing on the technical solutions. Four different data collection methods have been applied.Interviews and a questionaire with open-ended questions were the two primary tools. Adocument analysis and observations were applied as well.Examples from earlier research to relate to questions about digitization as an institutional andsocietal practice are presented.

AbstractThis degree project is about having meetings in The Swedish Social Insurance Agency, which is awide organisation. This work will concentrate on one of the projects going on within theorganisation which is travel-free meetings, where they are building a video meeting system thatallows the employees in the organisation to be able to meet with each other through the use ofvideoconferencing instead of physical meetings.In this work we will show how Kaikaku (radical system changes) along with Kaizen (continuouschange) can support an organisation to become more efficient and reduce wastage. We have donethis work in an organisation that is present in over one hundred locations in Sweden.The Social Insurance Agency has over 13 000 employees at over one hundred locations inSweden.The organisation has to be close to their customers and provide the best service aspossible. To be able to work in a uniform way, the employees get together and have meetings.Some meetings are just progress meetings and takes perhaps no more than two hours to complete.However, if seven employees from seven different locations need to have meetings, in the worstcase, they all have to meet in a common place.This is expensive for the organisation in travel costs, time and absence from work, but thetravelling also contributes to environmental pollution if the employees are travelling by a fuelpoweredvehicle.A whole day could go lost for having a meeting in about two hours if all sevenemployees went from their own cities to e.g. Stockholm for the meeting.Muda (wastage) of travel created several different types of Muda, namely:? Wastage with anticipation when the employees had to wait for e.g.

As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.

Sveriges ytstridskrafter hade länge en förmåga att hävda sig mot fiendens stridskrafter ute till havs på 1950- och 60-talen. Nedrustningsprogrammet av försvaret på 1960-talet innebar att teknikutvecklingen bromsade upp och flottans större fartyg kryssare, fregatter och jagare skulle bytas ut till en lätt flotta med små snabba enheter. Detta resulterade i att flottans taktik anpassades till ett tillbakadraget uppträdande längs med kustbandet och inom skärgården. Svenska officerare bevittnade på när Sovjetunionen rustade upp och utvecklade nya vapen och fartyg med robotar av högsta kvalité i Östersjöområdet. Detta hot medförde att officerarna i flottan ville satsa på ett långräckviddigt vapen för att bli mer jämbördig mot fiendens styrka ute till havs.Resultatet blev en svenskutvecklad sjömålsrobot, Robotsystem 15 (RBS 15), som infördes i marinen i början av 1980-talet.

Today the competition in the automobile industry is getting all tougher. The technology behind cars becomes more advanced. To get ahead of competitors car companies has to look into new areas of innovation.One important area is vehicle safety. Bigger companies have come so far in vehicle safety that difference between cars more depends on the car type (size) than the technology behind it.There is one area where vehicle safety that still has great opportunities for improvement, which is in active safety. The term active safety states that the car has the ability to identify treats and automatically respond to the treats.

The electrical grid needs to be changed in the future in order to manage more distributed and renewable generation and also to make it possible for electricity consumers to be more active and aware of their electricity consumption. This future grid is usually referred to as a smart grid. With the transition to a smart grid, new challenges occur. One method to determine those challenges is to perform risk and vulnerability analyses. InStockholm, the new urban district Stockholm Royal Seaport is built.

With growing economies and better living standards in many parts of the world today, there is a need of expanding the capacity of generating electricity. The alternatives for renewable energy technologies are not fully developed and have still some problems to conquer.The company Minesto has developed a technology that is called Deep Green. It is designed to gain electricity from tidal currents. Deep Green works in a similar way as a kite that is attached to the seafloor with a moving wire. It contains of a wing that moves due to the water current.

So- called ?Network Based Defense? (NBD) was introduced in Sweden in connection with the transformation of the Swedish Armed Forces in 1999. NBD is based on the U.S. variant Network Centric Warfare (NCW), which in turn is derived from research on the concept of Revolution in Military Affairs (RMA). In Sweden the concept was introduced and included not only the Armed Forces but was intended to also support the Swedish civilian agencies in order to create networks and hence share the available information and thus more effective crisis management and to provide more "bang for the buck." In developing the concept of NBD the Swedish Armed Forces used both economic and human resources, in the form of research, new technologies, new organization and new methods.Between year 2004 and 2006 the Armed Forces once again entered the process of reorganization.

Abstract New methods, techniques and tools for the building industry are constantly being developed and improved and launched on the market. The problem in the building industry development is not that the products are not good enough. The problem is instead that the existing construction companies do not choose to use these innovations, instead they continue to employ the technologies they already possess and master. This leads to the fact that the construction industry is, in the public eye, beeing seen as a conservative industry. AquaVilla is a company that basically produces houseboats.
