Use of computers and computer networks is nowadays a part of everyday life. You do not use them only at home when you sit at you computer, but you can use them all the time everywhere. This can involve everything from surf to any website when you are at home, to checking your email on your mobile when you are on your way to work. Most people do not think about how it really works when they try to access a web page by typing the address into their browser, but something that most people probably notice is how long it can sometimes take to access a web page.All items which are directly connected to the IP network have a unique IP address that is used to make it possible to communicate. The IP address is either a period separated sequence of digits representing 32 bits or a colon separated sequence of digits representing 128 bits, depending on whether the address is an IPv4 or IPv6 address.

Presterar Hedgefonder bättre än traditionellt förvaltade fonder?

Hedge funds have the past few years become an increasingly popular investment alternative and in the last decade hedge fund assets managed have quadrupled to USD 2000 billion, a growth rate of around 25-30% per year. One explanation for this substantial increase is that hedge funds' minimum limits on capital invested has declined, which have made ??them available to retail investors. The recent turmoil in financial markets has also contributed to investors finding their way to hedge funds, whose goal is to generate stable returns regardless of how the market develops.Using Sharpe?s, Treynor?s and Jensen's performance measures, I have investigated whether hedge funds manage to generate higher risk-adjusted returns than traditional managed funds.

Top-talents med förväntningar - En kvalitativ intervjustudie om att leda i spänningsfältet mellan performance management och top-talents på ett managementkonsultbolag

This paper aims to outline leaders' experiences of managing consultants from their company's performance management system. The study was conducted by qualitative interviews with senior managers and HR professionals within a management consulting firm. The aim was to describe the company's performance management system, their consultants and the challenges of leading in this context. The theoretical framework consists of previous research in leadership, performance management and management consulting. Within these research areas the authors identify a knowledge gap in leaders' perspectives on managing top-talents with performance management systems in the management consulting industry.

Ett meningsfullt utvecklingssamtal - En studie av ledning, chefer och medarbetares förväntningar utifrån teorier om organisationskultur

This thesis is examining if the management, the managers and the employees have a differentpoint of view regarding the purpose and the expectations of a performance review. Additionally it is an assignment from the Swedish company Flexlink AB with the purpose of constructing a new template for their performance reviews. The assumption is that if you manage to create one template for performance reviews that meets the expectations at all levels of the organization, it will contribute to create a meaningful performance review.We decided to study this from an organizational cultural perspective, since the organizational culture plays a significant part in performance reviews. Performance reviews are systematic conversations between employees and managers related to planning, information exchange and developing the relationship. Previous research indicates that if employees are satisfied with their performance reviews, they prone to be more satisfied with their work situation and have a higher organizational commitment.

Bedömning förr och nu : En studie i bedömning genom grundskolan

AbstractAimThe aim is that by using the curriculumcodes, analyze and compare four curriculums in physical education. The study begins in the elementary school introduction in 1962, and then makes three more strikes in 1980, 1994 and 2011.The questions that are addressed in this paper are,Which expression of competence code can be found in the different curricular?What are the expressions for performance code can be found in the different curricula?Is there any change regarding which code teachers use when they assess the students?Method  As a basis, the four curricula Lgr 62 Lgr 80, Lpo 94 and Lgr 11 in physical education are used. These four curriculums are studied and compared for similarities and changes in the assessment uses comparative content analysis. A number of publications in the curriculum codes are used in the analysis of the curriculum.

Konstruktion och utvärdering av Current Conveyors

Normally the operational amplifier is used as a component in active filter design. The goal for future components in filter design is large bandwith and the use of low supply voltages. The use of current-mode instead of voltage-mode circuits gets a step closer to the required performance. A component that use current as the signal conveying part is the current conveyor. In this report a comparative study between two current conveyor structures of second generation (CCII) is performed.

Experimentell jämförelse av Cassandra, MongoDB och MySQL

Context. Performance and resource usage is often an important factor for database driven services. Depending on the purpose of the application, choosing the wrong type of database may require unnecessary hardware upgrades or replacements. Objectives. This study investigates the differences in performance and resource usage between different SQL- and NoSQL-databases. The study is a comparison that focuses on how the databases perform in different applications.

Utveckling av ett hjälpmedel för träning och utvärdering av förare av tunga fordon

The purpose of this master thesis is to evaluate how internal vehicle information inScania buses and trucks can be used for evaluation of driver performance regardingfuel economy, vehicle wear, traffic safety, emissions and cargo damage. To someextent it was examined whether this information could be used for training the driverto a better driving style. In addition, a prototype for such a system was developed.By first defining what distinguishes a talented driver and how he/she differs from apoor driver, followed by a study of the internal vehicle communication, a system thatin real-time gathers and interprets vehicle data could be developed.The resulting system can with reasonably high reliability detect a number of trafficevents (such as braking, lane changing or hilltops). At each such event, the driver?sbehaviour can be evaluated.

Akuta effekter av assisterade hopp på kvinnliga idrottares hoppförmåga

Vertical jumping ability is an essential skill in many sports. The aim of this study wasto investigate the acute effects of assisted jumps on subsequent countermovementjump (CMJ) performance by female athletes. Nine healthy, trained female subjectsvolunteered to participate in the study. In a randomized order, they performed oneregular warm up protocol before testing their CMJ baseline value, and one warm upprotocol with an addition of five assisted jumps at 30% body weight reduction beforeanother CMJ test. Elastic cords attached to an overhead pulley system and to aharness around the subjects' upper body were used to reduce the body weight.Significant improvements were noted in jump height, 2.3 cm (7%), positive forceimpulse, 4.7 Ns (2%), vertical take off velocity, 0.1 m/s (3%), countermovement time,0.1 s (12%) and breaking time, 0.1 s (14%), p.

Interaktionens pris : Mot en ny konstkritik

The paper discusses the problems contemporary Swedish art criticism faces when judging performance art and interactive art. Problems include among others that performance art is collectively ignored in Swedish newspaper art criticism. This prevents art critics from fair contextualising of contemporary performance art. Down in the rabbit hole, performance by Tris Vonna-Michell and its reception exemplifies these problems. Performance and interactive art seems to be disturbing art critics.

Röjning på snö och röjning på barmark : effekter på produktivitet och kvarvarande bestånd

Approximately 4000-5000 hectares, of SCA´s forest land area in Västerbotten, are in need of pre-commercial thinning (PCT) every year. Within the management district, the areas annually treated with PCT must increase, in order to decrease the area with an urgent need for PCT. This can be done by employing more forest workers or entrepreneurs, by mechanized PCT or by an extended season for PCT. Positive experiences from a private forest owner, who started to carry out PCT when the first snow came and then continued for several months, gave an idea to investigate the possibilities to prolong the season of PCT. The purpose of this experiment was to compare PCT carried out when there was snow on the ground with PCT performed when there was no snow on the ground.

Den polska lastbilschaufförens verksamhet : Att i Sverige betraktas som egenföretagare eller anställd och vad blir inkomstbeskattningskonsekvensen?

Export is a top priority for Sweden's economy but for Swedish companies it may involve uncomfortable risks of exporting without sincere consideration. When the United Nations Security Council puts an embargo against a country, this often mean an import and export restriction. The thought is to push undemocratic regimes into respecting human rights. When the embargo is in force, however, the parties are not able to fulfill their contractual obligations, which practically means that the agreement will be suspended. The problem is what happens when an embargo is in force for a longer period of time.

The Surveillance Camera Players : Ett konstnärligt motstånd mot övervakningssamhället

The purpose with this essay is to examine how arts and politics integrate to raise urgent messages and call upon social changes. Performance art as an artistic manifestation against the surveillance society has been studied to clarify this integration and through an empirical examination of the anarchistic performance group The Surveillance Camera Players. This group formed in New York City 1996 as a manifestation against the increased use of surveillance cameras in public places in Manhattan. Through performance in front of these cameras, The Surveillance Camera Players are able to express their protest against the surveillance society which, occurring to them, violates citizens constitutionally right to privacy. The development and signification of the surveillance society are examined through theoretical perspective by foremost Michel Foucault, but also by contemporary scientist in that field.

Projektuppföljning - En studie av relationen mellan projektuppföljning och organisationsstruktur

This paper aims to examine performance monitoring in project organisations. The number of organisations that regularly performs projects as a key part of their operations grows rapidly, why this topic has become of large interest. Through a theoretical framework developed by Lars Östman in 1977, the performance monitoring system of the Swedish government-owned public utility Svenska Kraftnät is studied closely. The results from this analysis are then linked to an analysis of the organisation's internal structure through Mintzbergs generic organisational structures. Close connections are found between organisational structure and performance monitoring, which leads on to interesting observations about the connection between size of a project organisation and choice of monitoring method..

Diskkrypteringsprestanda i GNU/Linux

This thesis compares the impact on disk performance in a GNU/Linux  environmentwith three encryption algorithms: AES,  Serpent and Twofish in three different implementations: DM-crypt, Loop-AES and Truecrypt. For all three algorithms a key length of 256 bits is used.The thesis shows that the least performance impact during data encryption, and thus file writing, is reached by using AES or Twofish encryption implemented in DM-crypt or TrueCrypt. The thesis shows that some data operations with a sufficiently low processor utilization barely affects disk performance at all if encrypted using the optimal implementation and algorithm.It is also discovered that the performance impact during data decryption, or file reading, can be minimized by using the most efficient implementation and algorithm. The best results are met with the AES or Twofish cipher, regardless of implementation.An important conclusion that  is  drawn is that it is hard to determine a superior encryption solution for all purposes. However, by reviewing and examining the collected data from all aspects of disk performance the AES implementation in TrueCrypt is, with small marginals, determined to be the most optimal..
