Bärbara datorer, en möjlig källa för nickel- och koboltexponering av hud? : Direktvisande tester för nickel och kobolt på bärbara datorer och frisättningsförsök på en bärbar dator
Background: Since1994, the EU NickelDirective is limiting the release of nickel from objects that are in prolongedcontact with skin. Despite this, nickel is still the most common cause of contactallergy in industrialized countries. This could implicate that other productswith short contact to the skin, which are not restricted by EU´s legislation inREACH (Registration, Evaluation, Authorisation and Restriction of Chemicalsubstances), could be a source of nickel or cobalt exposure. There is no limitfor cobalt release within REACH. To determine if there is cobalt or nickelpresent on the surface of a material and if metal can be released in contactwith the skin, there are quantitative and qualitative methods, such as the DMG(dimethylglyoxime)-test, the cobalt spot-test and a method for releasedetermination according to EN1811.Objectives: Laptops are not included in the REACH legislation.
Att datorisera ett bibliotek: datoriseringen av skolbiblioteket på Sunnerbogymnasiet i Ljungby
The purpose of this paper is to describe methods to computerize a library and to compare theory with a process in a school library. The case study is based on a school library called Sunnerbogymnasiet which is situated in Ljungby. My questions are;- Which methods are parts of the process to computerize a library?- Which methods are used in the process in Sunnerbogymnasiet?- What does the practical process look like compared to the methods described in theory?In the paper I present the methods in the process according to the studied literature and compare these with a process at Sunnerbogymnasiet. The most significant result is that cooperation between the school library and the community library was the most important reason for the choice of library computer system.
Knacksensorplacering på lastbilsmotor
This work is an experimental study where knock sensor placements are investigated using engine tests. The aim is to studythe quality of the signal from knock sensors and how the signal for engine control is affected at different sensor locations on Scanias, engine DC13. To find out at witch position on the engine youcan get a usable signal for engine control, the engine is running while the knock sensors with advanced measurement equipment is connected to the engine. Evaluation of signals from the knock sensors are made in the computer program Matlab. The program is producing a seriesof plots, from these plots it is visually possible to draw conclusions and find connections.
Lagerprogram för Satellitlager
Texo Application has created robots that they call for satellites; with these you can feed in storage pallets into a satellite storage. Satellite storages consist of channels in height (e.g.3 to 8 pieces) and width (e.g.3 to 100 pieces). Channels can be different long (e.g. 5 to 200 pallets). At deposit of a storage pallet the truck insert the satellite in a channel and then the pallet, the pallet is driven into the channel until it reaches another pallet or the other end.
Installationsgränssnitt under Linux och Windows XP utifrån ISO 9241
This thesis investigates how different Linux-distributions installation
interface relate to the ISO 9241 standard,
parts 12 and 13, and how they relate to the installation interface of Windows
XP, with the hypothesis:
"There is a Linux-distribution whose installation interface according to
applicable HCIrecommendations is equivalent to that of Windows XP."
With the checklists provided by ISO 9241 an empirical study has been made, and
so comparable measurements of how well the Linux-distributions and Windows XP
follows the
recommendations of the standard was obtained.
By comparing the results from the tests similarities and differences between
the installation interfaces can be deducted.
As the result and the conclusion shows there are Linux-distributions whose
installation interface, according to the applicable HCI-recommendations, are
equivalent to that of Windows XP..

filmen vill vi visa unga homosexuella tjejer, eller som de medverkande benämner
det flator. Vi vill visa dessa i sina sociala sammanhang. Att vara lesbisk och
ung betyder inte att man måste leva annorlunda.
För att finna våra karaktärer sökte vi i hela södra Sverige.
Multimedia på folkbibliotek: uppfattningar och åsikter bland användare i Kungsbacka
Master thesis studying the use of multimedia on CD-ROM in a library setting by analysis ofqualitative interviews with nineteen persons.The thesis relates the study to some relevant issues in human-computer interface (HCI) researchand to the commercial market for multimedia CD-ROM products. Three main types ofuse were described by the persons interviewed: recreational, information seeking and usingmultimedia to learn more about using computers. Children and young people interviewed mademost use of the multimedia provided, whereas adults thought it to be less valuable as a sourceof knowledge for them personally.HCI research shows various results of using multimedia for educational purposes. Thecommercial market is dominated by American products which can have a negative effect onthe use of multimedia in Swedish public libraries..
Lärares erfarenheter av att använda sociala medier i undervisning
This study aims to investigate how and why teachers use social media to reach their students, and how they handle different levels of computer literacy among students.The purpose of this study is to investigate the experience of teachers using social media in their teaching. I have done interviews with two teachers, who use social media in different ways. One of the teachers makes her students publish their work on the Internet on wiki-spaces, and the other one use Facebook for discussions and teamwork. This report uses the pedagogy theories laid forth by Vygotskij as a vantage point to analyze the answers from the teachers. I have also looked at some of the published student texts on the Internet.This study concludes there are students who don?t have access to computers and Internet at home.
En utvärdering av fastighetsskötares användande av ett mobilt arbetsordersystem
När ett nytt system kommer i användning så är det viktigt att följa upp utifall
systemet fyller sin funktion och är användbart. Enovation i Karlskrona har
utvecklat ett mobilt arbetsordersystem till fastighetsskötarna på
fastighetsbolaget Gallionen. Det är det systemet som vi har utvärderat i detta
arbete.
Anledningarna till att systemet har utvecklats är många. Den viktigaste
anledningen är att fastighetsskötarna ska slippa åka fram och tillbaka till
receptionen för att hämta nya arbetsordrar och slippa ha med sig en massa
papper.
Interaktiv Produktpresentation åt Abu Garcia
Detta projekt har producerats i samarbete med Abu Garcia i Svängsta, Blekinge.
Vårat projekt är en interaktiv produkt presentation gjord i flash med inslag av
3d, video och ljud. Våran tanke är att användaren ska kunna se hur en
Ambassadeur Record fiskerulle ser ut både på insidan och utsidan, hur den
fungerar och vad som gör den så unik.
Det finns också video filmer som beskriver tillverknings processen, och hur man
som förstagångs användare använder en Ambassadeur rulle.
Design och bakgrundsljud är anpassad så att den ska väcka en känsla av fiske
och fridfull utomhus miljö..
BIM vid installationsprojektering
Planet rendering plays an important role in universe visualization and geographic visualization. The recent tools and methods allow better data acquisition, usually with very high resolution. However in computer graphics, there is always the limitation on the resolution of geometry and texture due to numerical imprecision. Not many applications can handle high resolution data effectively.This thesis introduces, Implicit Surface Scene, a level of detail scene management inspired by dynamic coordinate system and SCALEGRAPH? which change over time depending on the current camera position relative to the planet surface.
Registrering av faktisk närvaro i förskolan - vem berörs?
Every municipality in Sweden is responsible for offering its citizens adequate childcare. Parents hand in a preliminary schedule to the preschool for when their child needs to be in childcare, and based on this the preschool staff is scheduled. Some municipalities measure the actual time a child is in childcare. The essay idea comes from when I heard that one municipality was thinking of register the children's actual time in preschools. I started thinking on how to solve such a task.
Minnet sviker Aldrig : Att utnyttja volatil data i Krypterade system
When the use of encryption amongst the regular computer user grows morewidespread than ever it makes the life of the IT-forensics experts difficult.Hampering the judicial investigations that otherwise could have lead to convictions.In this report we will treat the subject of crypto analysis with a focus on decrypting files and devices encrypted with the software TrueCrypt. A solution will be presented that can facilitate the future work involving encryption. The application DFEAT that has been developed during the writings of this report is faster than the corresponding software EFDD, and attacks both partitions and bitwise copies of entire harddrives where PKF fails.DFEAT is a lightweight application that is almost 50 times smaller compared to EFDD and 200 times smaller than PKF's portable version..
Virtuell hållfasthetsprovning av en turistbuss
The competitive nature of the automotive industry has always implied a necessity to improve product development concerning time-to-market, cost and product quality. As capacity of computer-aided engineering (CAE) tools has evolved, so has the strive for simulation-driven design. Virtual durability testing using full vehicle models is one of many challenges posed in front of vehicle manufacturers when computer simulations are given a key role in product development.This thesis has been initiated as a preliminary step towards implementing dynamic virtual durability testing in the development of buses and coaches at Scania. The objective has been to assess the predictability of a full vehicle coach model and to what level of precision structural loads can be predicted. Previously performed proving ground testing of a Scania Touring coach has been the basis for the modelling and simulations in this thesis.A virtual model of the Scania Touring coach has been created in multi-body simulation software package MSC.Adams.
Återkallning av Meningsbärande Enheter med Hjälp av Stödord och Internet : Ett kvasiexperiment för att undersöka återkallning av semantiskt meningsbärande enheter med externa hjälpmedel
The current study sought to examine if post-produced semantic memory cues are a good aid for memory recall. It also focused on remembering units with a meaning, instead of just remembering lists of words. In the current study a factual text was used where the participants were tasked with recalling as much information as possible either with the aid of cues (keywords written by the participants themselfs), computer with Internet or no aids at all. The results showed that keywords are significantly better for memory recall. The results were discussed in regards to modern models describing semantic memory.
