Vatten- och närsaltomsättning i Göta Älvs mynning - Studie av boxmodell
IP-adresserna under IPv4 är inte tillräckliga och har på många delar i världen redan tagit slut. IPv6 erbjuder många fler tillgängliga adresser och övergången till protokollet har redan börjat. Det Gävlebaserade företaget Interlan erbjuder en tjänst som kontrollerar om kommuner och myndigheter i de nordiska länderna är nåbara via IPv6 samt om de är säkrade med DNSSEC. Denna rapport beskriver jobbet med att förbättra och göra deras tjänst anpassningsbar för flera länder. Processen som beskrivs är parametriseringen av skripten som samlar data, skapandet av en databas att lagra data i, och ändringar till hur data presenteras så att det går att lägga till flera länder..
Tid är dyrbart och det gäller att göra det bästa möjliga av det man har : Utvärdering av en ledningsgrupp baserad på intervjuer, enkätundersökning och observationer.
The purpose of this study was to identify the positive and negative aspects of the work and dynamics of a management team and from that recommend how the team can improve. The aim was also to investigate whether there was a gap between how the members of the management team comprehend themselves and how the project, section and team managers comprehend the management team. The management team contains of seven core team members and is the head function of a research and development site in central Sweden. The results are based on interviews with the present members of the management team and three former members, a survey among the project, section and team managers and by participating observation on meetings with the team. The results show that the management team is an overall well-functioning team that with some changes and improvements, especially concerning communication and information, can reach even further.
1553-Simulator. In-/uppspelning av databusstrafik med hjälp av FPGA
At Saab Aerospace in Linköping, components for measurement systems to the fighter aircraft JAS 39 Gripen are developed. In this activity you sometimes want to record the traffic transmitted on the data busses that connects different sys-tems. This traffic on the data busses is using the military standard MIL-STD-1553. This project has aimed to create a system for recording and sending 1553-data. The system is used on an ordinary personal computer, equipped with a recon- figurable I/O card that among others has a programmable logic circuit (FPGA).
Öppna format (Lagring över tid)
Vi lagrar data mer än någonsin. Idag lagrar vi enligt analysföretaget IDC1
(2007) upp emot 36 gånger mer information än vad vi gjorde under 1998.
Men få tänker på säkerheten vid lagring av data. Med säkerhet menar vi här
säkerheten att datan som lagrats fortfarande kommer att kunna öppnas om 15
-20 år.
Med format i denna studie syftar vi huvudsakligen på filformat. HTML,
JPEG, GIF, etc. är exempel på filformat i vilket information kodas för att
kunna lagras.
Utvecklingen av energieffektiv teknologi i svenska datorcenter
This thesis investigate how energy efficient measures has spread throughout the data centers in Sweden. These questions are put up against a theoretical use of such concepts such as green IT, technological evolution, large technical systems and knowledge dissemination. These theories are used to answer the questions that are encountered during the study, such as how green IT is approached, how big of a role environmental thinking has had in the evolvement of these new technologies. The study has been conducted in a longitudinal manner, it is an observation of the phenomenon that is data centers over a longer period of time. 23 non structured interviews spanning over 27.5 hours of recorded material have been conducted alongside a study of archived material.
Modellering av 3D-miljöer utifrån geografisk data
Simuleringar används i många sammanhang för att underlätta förståelsen för händelser och förlopp som annars kan vara svåra att överblicka. Ofta är det mycket data som ska förmedlas till användaren.I de fall visuella representationer av simuleringen ska visas i realtid måste data sållas bort så att en interaktiv bildfrekvens uppnås samtidigt som betydelsefull information inte får försvinna.Vid Totalförsvarets forskningsinstitut, FOI, används simulering och visualisering som ett verktyg för att studera de komplexa duellsituationerna mellan medel och motmedel (telekrigduellen). Ett verktyg har i detta arbete tagits fram för att kunna använda sig av de stora geografiska områden som behövs i simuleringarna.Resultatet av arbetet är en applikation som utifrån geografisk kartdata skapar ett 3D-landskap som lämpar sig för realtidssimulering..
Ökat beslutsunderlag tack vare data warehouse/business intelligence
Arbetet beskriver ett systemutvecklingsarbete som innehåller kravfångst, analys och design av en data warehouse/business intelligencelösning till Svenska bordtennisförbundet. Svenska bordtennisförbundet/SBTF/ behöver utöka sitt beslutsunderlag för att kunna fatta strategiska beslut. SBTF behöver även få bättre kontroll på sin verksamhet för att kunna sätta, utvärdera och följa upp mål. SBTF önskar lösa detta genom att skapa ett data warehouse till vilket data från de olika systemen laddas för att därefter kunna presenteras för användarna genom business intelligence. I kravspecifikationen framkom att klubbarnas medlemsregister, alla tävlingsspelare, all träningsstatistik och de matcher som spelats i Sverige sedan 2011 var det dataunderlag som skulle ingå i ett data warehouse.
Kvalitetssäkring i tjänsteföretag : En jämförande studie mellan Ving och SIQ:s riktlinjer för kvalitetssäkring
When managing the quality of a service producing industry?s products, the industry faces greater challenges than the manufacturing industries do. Today?s globalization puts further pressure on service producing companies around the world to work at their absolute maximum. So, how do service producing companies work to manage quality? In this essay the writers take a deeper look at the travel agency Ving, part of My Travel Northern Europe.

Tidssynkroniserade mätningar i vattenkraftstationer
Vattenfall and Svenska Kraftnät perform start-up tests, where hydropower generators are used to power up the electrical grid in case of a blackout. To monitor the electrical grid, Phasor Measurement Units (PMU) are used. Each PMU is individually equipped with a GPS-receiver to precisely timestamp the data relative to the official time UTC. During the test, it is also of interest to timestamp the measurement signals from individual hydropower generators to later compare with PMU-data, and thus study the power grids impact on the generator. The aim is to work out an appropriate method to make these measurements and to build a data acquisition system, capable of timestamp data relative to UTC, from a generator in one of Vattenfalls hydroelectric power stations. The problem is that the generator is located in an underground station which hampers the reception of GPS-signals and wiring should be avoided if possible. Time synchronization has been solved by using Vattenfalls network, which is synchronized by the network protocol NTP.
Undersökning av riskfaktorer med produktion och inmatning av data till en databas
Syftet med denna rapport är att undersöka vilka riskfaktorer det sociotekniska systemet bidrar med vid inmatning av producerade data till en specifik databas. Denna undersökning använder STAMP-metoden (Systems Theoretic Accidents Models and Processes) för att finna riskfaktorer i systemet. Metoden utgår från att samla data om systemet genom intervju, observation samt analys av annan dokumentation kring databasen för att sedan applicera STAMP-analys på dessa. Resultaten pekade på ett antal riskfaktorer vid inmatningen av producerade data, dessa kretsade primärt kring problem med existerande säkerhetsåtgärder, avsaknad av träning samt bristande kommunikation. Resultaten ledde till en slutsats om förbättringsåtgärder på dessa punkter.

The structure of the thesis is based on opportunities to attract businesses to the region, the need of establishments in the region and benchmarking with establishment strategies of other cluster initiatives. The identified opportunities are the local business relationship with ABB, the prerequisites of life quality in the region and the availability of financial support. Further on has a number of opportunities to be developed been identified; diversification of the existing businesses, an expansion of the cooperation with universities and to simplify the contact with local authorities. Challenges that HVV is facing is: creating a more dynamic labor market, secure long-term labor supply, spread the image of the brand HVV and finally putting HVVs geographic scope. Two of the identified needs of establishments are strategically important: to establish a third-party logistician and commercializing systems for distributed generation and energy storage.
Läraren som ledare och hennes roll i elevers kunskapsutveckling och socialt uppförande
Over the past ten years, the pupils' performance and grades has fallen and the number of competent to high school has decreased gradually. The Swedish school has been criticized and the role of the teachers has been questioned, among other by the media. In autumn 2007 Johannesskolan, one of Sweden's tenth worst schools replaced the ordinary teachers of Class 9A against eight of the country's "main" educators with the goal of the class to become one of Sweden's third major. The teachers have the autumn term in which to achieve the goal and the outcome will be measured by national tests in core subjects Swedish, English and Mathematics. The aim of this paper is to examine the role of the teacher's leadership in relation to the pupils' social and intellectual development, and identify common leadership of these eight educators.
Radomoptimering för luftburna störsändarkapslar
These studies are done in behalf of Saab AB AVITRONICS in Järfälla in the form of a thesis atthe Royal Institute of Technology in Stockholm.The task was to examine the parameters that plays a role in the construction of modern radomesoperating in broadband applications.This was interesting for Saab to get an indication of which way they should go at the newdevelopment of radomes for the next generation of equipment for electronic warfare.After a thorough analysis of the influencing parameters, a optimization application was made toget a automated way to get a radome design by specifying data on the radome size, airloads,materials, etc.This is to minimise the time of the laborious work that radome development.inply.This was solved by letting ANSYS calculate the strength of the radome structure and MATLABcalculate electromagnetic data and cost models of different sizes and materials.All these parameters woven together with the optimization tool modeFrontier picks data from therespective program and perform an optimization algorithm and then iterate a step and sends thisdata to calculation programs for the new input data. In the end, we have received a convergedpoint with our optimal solution.For the presumptions and limitations for which applied for this thesis, the result was prettyintuitive. That is to say that the smaller radome - the less materal is needed and lowermanufacturing costs results in the cheapest solution possible. The reality is not so simple. Whereyou have to take more of the electrical details such as the effect on the transmitter as a majorfactor..
To derive quality from quantity
The purpose of this master thesis is to present a model that illuminates the important factors when deriving technical information from market data within a company. For companies to be able to become and stay competitive in the market, product quality is an important factor. Whilst good product quality leads to customer satisfaction and loyalty, lack of quality brings costs in service and replacements. To improve product quality, the developers need information and knowledge about what quality issues affect existing products. Most companies gather data from market about known issues, but in order eliminate known quality issues in new products; this data has to be transformed into information and knowledge.
