Forensic Carving from Unallocated Space
Computer Forensics investigations have become more and more common while
investigating IT-related issues. From experience, hard disks, USB thumb, memory
sticks contains information that might be useful. Computer Forensics is
regulary conducted by Police, Customs, Tax investigators but also within
private companies and organisations. However, there are areas within the
storage device that are not part of the organisied structure that a file system
gives. The reason for that might be that the information has been erased by
intention, a virus destroyed the file system and so on.
Styrd borrning eller konventionell schaktning : en jämförelse av två rörläggningsmetoder
This is a diploma thesis executed as a part of the examination of the educationalprogram Building engineer ? Construction management at Halmstad University. The aim of the thesis is to compare and evaluate conventional open-cut pipe-laying withhorizontal directional drilling. The thesis includes a comparison of the economic,environmental and time-based aspects of both methods and discusses which factorsthat determine the optimal choice of method.The study is mainly based on previous studies regarding the subject and oninterviews with professionals from the industry.A fictional project with five realistic cases of pipe-laying scenarios was compiled,sent to different companies for calculation, evaluated and compared. Our conclusionregarding when it?s suitable to use which method is entirely dependent on thespecific project.

Transporter på väg - En studie över Sveriges lastbilscentralers metoder för att möta ökande drivmedelspriser
Background and problem: In the last few years the threat against the environment and especially the emissions of carbon dioxide has become increasingly debated. The government have set up a goal to lower the emissions of carbon dioxide with 40 percent until 2020 compared to the level in 1990. The emissions in the transportation sector have, in contrast to the total emissions, increased since 1990 and will continue to increase unless powerful control measures are implemented. The lorry centres have to use strategies to answer to these external threats which lead us to the two questions of this thesis: - What methods do the lorry centres use actively and which do they consider as the most important methods for fuel saving? - Are there any differences which methods small, medium and large centres considers as important? Purpose: The main purpose of this thesis is to examine which methods lorry centres use actively and which they consider as important for fuel saving.
Framtagande av kravspecifikation för standardsystem
There are several methods and models within the areas of software engineering on how to proceed during a software development process. For each of these methods and models there are benefits and drawbacks, depending on how you choose to look at them. A difference of principle between the different models is that they either advocate iterative development or not. In parts of software engineering one makes use of different methods depending on which is most fitting in a specific situation. There are several methods on how to recieve more qualitative data from the end-users during the requirement collection, but the reappearing pattern is still user centric participation, which means that the user participates more actively in part of or the entire development process.
När delar blir till helheter eller helheter blir till delar : En studie om olika läsinlärningsmetoder
AbstractThe present thesis examines reading acquisition. The aim of the study is to gain a deepened understanding of various methods used for reading acquisition, how teachers? are dealing with these methods and what aspects require special attention. The overall research question of the thesis is: How can one assess children?s future reading ability and identify a method that is appropriate to this ability? The overall aim leads to several more specifically addressed issues.In the theoretical part, different perspectives and theories about reading acquisition are presented along with different methods for how to work in order to facilitate reading.
Jämförelse av två mätmetoder för mindre gasvolym
Two different methods for measuring biogas production were used, gas meter and gasbags. The gas meters were electronic and counted each time a certain gasvolume passed through them. The gasbags collected the gas that hade passed through the gas meter until a manual measuring could be done. The two different methods gave the same result for a volume at three liters but for a volume around 0,2 liters they did not. Accuracy and precision for the gasbags was more exact than for the gas meters even if the method was difficult with a lot of different elements that could affect the result.
A comparison of transporters? paddle use when unloading pigs at slaughter
Today, pigs are moved on farm, between farms, between countries and to abattoirs. This movement of live pigs requires handling practices that are designed for the purpose. The objective of this study was to research the use of paddle in moving pigs, to investigate if there were different methods of paddle practice, explore the time efficiency of different kinds of paddle use and if there were any time variations in methods that varied in intensity of touch. This study was done on two Swedish abattoirs for a total of five weeks. A total of 22 transporters working at two different abattoirs where studied during unloading of pigs at the abattoirs.
En studie i användbarhet: En kritisk analys av användbarhetsstudier i biblioteks- och informationsvetenskap
Usability studies are not a central field of research in library and information science. Although literature in library and information science treats the importance of usable user interfaces quite extensively, the literature does not significantly treat potential problems in measuring usability. The aim of this master thesis is to investigate, through a critical analysis, the methods used when conducting usability studies in library and information science. The critical analysis is based on potential problems in measuring usability identified through a literature review from the field of studies Human-Computer Interaction, the concept of usabilitys original domain. The material which is to be analysed, is chosen from one library and information science journal Journal of the American Society for Information Science and Technology.
Att förbättra elevers läsförståelse : Hur lärare undervisar elever för att eleverna ska nå ökad läsförståelse i årskurs 5
The purpose ot this study is to investigate how two teachers of fifth grade say they are working with reading comprehension in their teaching. Furthermore the aim is to investigate how the teachers' instruction in reading cmprehension expresses itself. The study was conducted from a teachers perspective and the questions that the stydy will answer are: How do two teachers in fifth grade believe they should teach in order to develop reading comprehension among their own students, and what methods, activities and materials are the teachers using in order to develop students' reading omprehension in the educational practise. The methods used during the study were interviews and observations. The observations were made in order to complete the picture from the interviews.
Agila metoders påverkan på testare
To assure good quality the software needs to be tested to find errors and to verify that the programme meets the customer?s expectations. Traditional methods are usually used in software development and means that a number of predetermined steps are followed. By using agile methods the development can more easily be adapted to the changes on the market. With these methods the testing is carried out continuously throughout the project.
Kyrkan som immateriellt kulturarv En studie i kulturvårdens förhållningssätt till liturgiska värden
This master thesis aims to examine the methods of the conservation field and their visionabout maintenance and change, in terms of liturgical values. This is to be able todetermine if there is a need to develop the methods that the field of conservation has tosafeguard the intangible cultural heritage of the churches.This is mainly a literature review, focusing on different tutorials from the Swedish nationalheritage board, and different texts on liturgy aswell as Unesco's Convention for theSafeguarding of intagible Heritage (2003), ratified in Sweden in January 2011. A casestudy of the practical work has been carried out on three churches that have undergonechange. The application process and the results were important for this study.The conclusion is that the conservation field have ambitions to preserve the liturgicalvalues, but they do not have sufficiently developed methods to do so. Nevertheless, itappears that most cases of change in churches, increases the liturgical values..
Slumpmässig Informationssökning eller ?Jag talar hellre om inspiration?. Skådespelares slumpmässiga informationsanskaffning
The aim of this study has been to investigate actors? methods for acquiring information that is necessary for their profession, with a focus on the more random methods they might possibly use. The study is based on the following questions: What information needs do actors have in relation to their profession? Which methods do actors use to procure information? Which information systems do actors use? What role does the library play in the actors? acquisition of information? Through an interview study with 10 informants a picture is formed of the actors? information behavior. With the help of theoretical ideas regarding random methods of acquisition, we describe which information needs actors have and how they acquire that information.
Bråkiga barn -Att förstå och bemöta utagerande barn i förskolan
Inspired by the article Special support on dubious grounds published in Teachers News (2010), we chose to examine the methods and procedures regarding acting out children without diagnosis. In preliminary work, we discussed the various forms and causes of acting out behavior among children in preschool and supervision and conflict management. The topic seemed relevant since we on several occasions experienced a feeling of inadequacy and lack of knowledge in our educational role both in teacher training placement time and during our working years as supply teacher and graduated child minders. Based on our past experiences and interests of acting out children without the diagnosis, work limited extent and time aspect for the course of the work we chose to only interview three pedagogues. Through the interviews, we wanted to compare these three pedagogues description of their work around acting out children without diagnosis in relation to accepted theories such as structure and clarity.
Dagvattendammars reningseffekt : påverkande faktorer och metodik för statistisk modellering
Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.
