Remburser och andra säkerhetsarrangmang vid internationell handel

AbstractWe live in a world today that is characterized by the Internet. We can get hold of people on the other side of the globe whenever we want and we can purchase what ever we want, from who ever we want, anytime we want. This development has made it important to find systems of dealing with the payment in a safe and secure way, both for a private person as well as for a company, when you do transactions with people far away, and those systems is the core of this essay. As a private person you sometimes need to transfer money to family members who live abroad and you can then use clean payments. This means that banks all over the world has systems which makes it easier when their customs wishes to transfer money abroad.

Processchemaläggare för mångkärniga processorer ? Fördelning av minnesbelastning i NUMA-system

For systems with multicore processors contention for shared resources is a problem that occurs when several memory-intensive processes are executed in parallel within the same memory domain. This contention has a direct influence on the performance of the system and is a complex problem that has been recognized for a long time. An attractive and actively studied way to minimize this problem is by using a process scheduler adapted to allocate processor cores in a way such that contention for shared resources is minimized.With the introduction of multicore NUMA-systems (Non-Uniform Memory Access) the situation has become even more complex. In these systems the access time for processor cores to different memory domains vary depending on factors such as distance and load. Thus, the process scheduler also has to consider where the memory of each process is placed to minimize the distance and balance the load on each memory domain.This report presents a user-level process scheduler for a NUMA-system based on the multicore processor Tilera TILEPro64.

Grafisk utvecklingsplattform för signalbehandling - Design och implementation

We have different kinds of signal processing everywhere around us in our everyday life, in our cellphones, when we are listening to music, watching TV etc. This makes signal processing a very interesting and important technical area, where the demand of skilled engineers sets the limit of what is possible.Working with signal processing requires in-depth knowledge in areas such as mathematics, physics, electronics, and other related areas. For this, it has traditionally been demanded by a talented developer to also master the advanced programming languages such as C / C + + and Assembler.This has begun to change; today there are several companies that offer graphical development environments for signal processing, environments where programming skills are not needed anymore, and the focus can be on signal processing instead.The goal with this project is to build a corresponding graphical development environment to reach an understanding of what is required of these systems, and also to grasp what opportunities that are available within graphic programming. Inspiration for the work has partly arise from some of the tools available on the market, and partly from previous theses that have been written about graphic programming.The challenge lies in creating a program that can execute signal diagrams in real time from given signal blocks, and be able to handle feedback loops in an efficient way and to do so at the lowest "cost" in terms of clock cycles as possible. This should also be compared against to code, compile and run a complete signal diagram directly.To increase the usability it should also be possibility to externally manage in real time the parameters of the signal diagram during execution.The interface is a separate program, which is to some extent similar to Matlab Simulink, where a signal diagram is drawn up graphically by connecting wires between different signal blocks.

Klassifikationssystem på webben: Traditionella och nya

The aim of this thesis is to investigate the opportunities of classification of web pages. Two classification systems are compared; a library classification system traditional and a system that is developed for use on the web new. UDC is chosen to represent the traditional systems, and Yahoo! represents a so called new system. UDC is used by NISS Directory of networked resources, which is a directory that uses the system for organisation of electronic resources. Both systems are analysed from two different perspectives, a multidisciplinary and a timeperspective.

Installation av övervakningssytem ombord på fartyget M/S Andromeda

This report is regarding an electrical installation of an alarm system on a post fishingboat called Andromeda. The background of the installation was an earlier andinadequate alarm system that led to a motor failure. The ship was taken out of serviceand was sold to Björn Magndahl who rebuilt it to a yacht.The project was conducted partly by developing the existing systems, partly bydocumenting the work by means of electrical blue prints. Except the alarm systems, aninstallation of the frequency control unit for the bow thruster was installed.The installation was working fine and the outcome of the documentation was handedover in a form of a binder during the test drive of the systems and the assignment wasapproved..

Utvecklingssamtal - utifrån elevens perspektiv

My aim with this diploma work is to find out if the students consider development deliberations as a good forum in order to promote their knowledge development or not. I have also examined if the development deliberation is experienced as giving for the pupil or not, what I have been studying from the pupil's perspectives.MethodI have implemented three qualitative interviews with three students from class nine in a compulsory education that lies in Botkyrka municipality. There, I have also an implemented questionnaire survey with two half classes from same class.Materials To my study I have linked literature where research aims himself in on how teachers have worked with development deliberations in the school.Results Students that I have interviewed does consider development deliberations as a knowledgep romoting forum, but most as a forum for clear about study results. The students in the survey consider development deliberations as giving only when the result turns out to bee good.Importance for teachers As each development deliberation is unique, you can not come to a certain implication that all deliberations are experienced in the same way as the result shows. But that can last stakeholder for the teacher is to see how one development deliberation can to be experienced of several students.

ATTITYDER, VÄRDERINGAR och INSTÄLLNING till FRAMTIDA ARBETSLIV : ?En kvalitativ studie med sex unga kvinnliga beteendevetarstudenter?

The purpose of this paper was to investigate what young behavioral science students, born in the 1980s, think is important in their future work life. The purpose has also been to investigate what attitudes the behavioral science students have towards their future work life, and what place work has in the young behavioral science students lives. After clarification of above, the aim has also been to compare the results with former research. Thereafter the purpose has been to investigate whether traditional work motivation and job satisfaction theories are applicable for young people today. The empirical material is based on interviews with six women who study behavioral science at various levels.

The Effects of Technology-Based Self-Service on Grocery Retail : A Swedish Case

Technology based self-service (TBSS) used in supermarket self-scanning checkouts is a relatively new phenomenon in Sweden. Studies on TBSS as a self- checkout device have been formerly carried out but with focus on the customer perspective. The authors therefore saw a challenge in covering the self-scan checkout concept, from a company perspective. The purpose of this research paper is to investigate, through a management perspective, the changes brought about by implementing an innovative TBSS system in Swedish supermarkets, and its effect on the competitiveness of the company. This is done by presenting and linking the theoretical framework and empirical study in the research.

XML som informationsbärare för EDI

Information handling has been a key issue for different companies for a long time. Electronic Data Interchange (EDI) is used to transfer different business documents from one company to another. This is done in such way that the information itself is separated from how this information is stored and handled in the companies internal systems. As different companies have different systems there is a need for a standardised format for this exchange. There is a big difference between EDI-systems based on what kind of EDI-standard is used. The most common standard in Europe is EDIFACT, but with increased interest of using the Internet for business communication there is a need for a standard that is adjusted for use over the Internet.

Den Digitala Identiteten : En kvalitativ studie om identitetskonstruktion på internet

The purpose of this paper is to increase knowledge and understanding of how an identity is constructed on the internet and if it is different from the everyday identity. To analyze this, I have studied the theories of how identity is constructed in everyday life and then applied this on the empirical data that I have collected. In this study, I have chosen to pursue a qualitative approach using semi-structured interviews to gather the empirical data. In the study, six informants participated and all of them has an active social life both on and off the internet. The results that I have found in this study shows that an identity online is constructed in a similar way as it does in real life, however, some limitations that exist in everyday life do not exist online.

Ger det fria arbetet frihet : En studie om balans mellan arbete och privatliv

This qualitative study treats the construction and maintenance of balance between work and private life and how flexibility in the workplace is perceived. The study was conducted using semi-structured interviews and these have been conducted in five large companies around Gothenburg. The analysis and results are based on the phenomenographic method approach and the final results were four themes: Balance, Flexibility, Combining family and work and lifelong learning with related subcategories. The result shows that the construction and maintenance of balance between work and personal life is something that is tied to the indi-viduals and the current situation in life. Two of the most common strategies to maintain a dis-tinction proved to be planning as well as other activities, in order to move the focus away from the work.
