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.

This thesis contains a usability evaluation of ?Barnplay?, a Swedish video-on-demand service targeted at children. The objective of the study was to identify usability issues in the video service and to develop measures on improving the user interface, with special focus on adaptation to the broad target group of 3-11 year olds.The study was conducted by first mapping established practices in designs of VOD-services targeted at children, followed by interviews and usability tests with children between 2-11 concerning their use of ?Barnplay?. Based on the initial data collection, a prototype was developed and then evaluated by usability testing and A/B-testing.The main conclusion of the study is the need of better individual adjustment of the video content selection to better appeal to different age segments within the target group.

The world's natural resources are constantly being reduced, which increases the pressure on companies to actively engage themselves in environmental activities. Meanwhile, stakeholders focus is being broadened and it is now important not only to supply a particular product or service but also show that they are actively pursuing an environmental agenda. Companies can use various tools to aid in environmental efforts, but also to demonstrate to the world that the company is actively engaged in environmental activities. One such tool is the environmental standard ISO14001 which provides the company with guidance and support on how the business must manage its environmental efforts. To show a business' progress in environmental performance, it is advantageous to use environmental performance indicators as they enable stakeholders to easily understand how the business works with environmental issues.Authors in the field explain that the environmental management system propagation is limited in service organizations.

Cloud Computing är det stora modeordet i IT-världen just nu. Det har blivit mer och mer populärt på senare år men frågor har uppstått om dess prestanda och säkerhet. Hur säkert är det egentligen och är det någon större skillnad i prestanda mellan en lokal server och en molnbaserad server? Detta examensarbete tar upp dessa frågor. En serie prestandatester kombinerat med en litteraturstudie genomfördes för att få fram ett resultatet för detta examensarbete. Denna rapport kan komma att vara till nytta för de som har ett intresse av Cloud Computing men som saknar någon större kunskap om ämnet.

Formulation and testing of a new type of chainsaw lubricantThe company Agro Oil has come up with the idea of developing an environmentally adapted chainsaw lubricant with a new unusual base fluid. A field test with a tree-harvester shows unsatisfactory low temperature properties and high wear. In this work the viscosity, price and pour point of different combinations of the given base fluid and three other base fluids have been investigated. Desired viscosity and price are determined for different formulations. The new lubricants tested show lower pour points than almost all products on the Swedish market.A test equipment has been developed to investigate the wear.

The aim of this thesis is to examine interactivity in the context of performance-based interactive art. The questions asked are: what are the conditions of interactivity, how interactivity happens, and what artistic results it may yield. The method is an analysis based on close studies of three performance-based interactive artworks by applying theories of interactivity, audience participation, and collaboration.First, current theories are outlined, after which, the three artworks are introduced in detail. Next, the artworks are examined, thematically rather than individually, expanding on parameters such as the degree of artistic direction of the artwork, the degree of agency allowed to the spectator in their interaction with the work, and the idea of the ?passive? spectator as being ?activated? by interactive art.

By conducting interviews, studies as well as scanning the current scientific landscape, this paper examines the opportunities of increasing current capacity within the public transportation system in Stockholm with simple financial means for the benefit of the travelers. The paper focuses on the central station of the subway system and how adjustments of processes carried out in relation to the turnstiles could increase performance within areas of interest, given the preferences of the travelers. The theoretical framework of the paper includes models from the field of capacity management as well as theories related to the pedestrian behavior. Applying these theories and models to the collected data, the paper derives some main conclusions. First of, people using the public transportations system, and especially the subway, consider speed and dependability as the most important performance objectives for the caretakers of the public transportation system, SL and MTR to master.

There is a strong debate in the media about the CEO compensation in the listed companies and whether they deserve their high rewards. Many previous studies have shown differences in the reward system depending on the ownership structure, mostly testing for only ownership concentration or ownership category. This study aims to investigate how the influence of the owners affects the CEO reward system, testing for both the level and the structure of the reward. The sample used in the investigation is Swedish listed corporations and consists of 251 observations. A survey was also conducted but due to low response rate and because the answers are not representative for the whole sample the survey will only be used as an illustration.

ABSTRACTBackground: On behalf of the Orthopedic clinic, Västerås, a study has been conducted with focus on comparing the results after conservative and surgical treatment due to complete achillestendon rupture.Aim: To compare results when testing the active and passive range of motion, calf muscle endurance, estimation of pain related to the achillestendon and self-efficacy to be physically active for individuals who have undergone conservative or surgical treatment after complete achillestendon rupture.Method: 14 individuals afflicted by complete achillestendon rupture in 2010 were recruited as a purposive sample. Examination were conducted of: Ankle range of motion with a goniometer, calf muscle endurance through a toe-raise test, estimation of pain intensity related to the achillestendon by VAS and self-efficacy to be physically active through ?Exercise self-efficacy scale?. P-value and the median were calculated.Result: The results of ankle range of motion and calf muscle endurance were based on the difference between the injured and the healthy side. When testing active plantarflexion the conservative group had a median of 4 ? and the surgical group had a median of 10 ?.

In this study the reliability of dominance profiles as a method of establishing a person's learning style was tested. Eight students at Malmö Academy of Music tried three different ways to learn a short melody at the piano. In this way, their preferred way of learning things (either visual, auditive or kinestetic) was established. Five of the students did best when they used a visual cue to learn a melody, and the remaining three did best when auditive cues were used. All but one of the students had the worst result in the kinestetic trial.

During the spring of 2014, I have investigated the visual culture of Lolita as practiced in Sweden and Japan. My focus has been on the performative aspect of Lolita. By looking and participating in this colorful subculture, I have met people who are living the Lolita lifestyle on a daily basis as well as former Lolita practitioners. My main concern has been how does one use Lolita.I?ve tried to investigate if it is possible to look at Lolita as being more than just a clothing style.

The aim of this study is to investigate oral peer review on argumentative speech and to study the attitudes towards this peer review. The investigation was performed in an up-per secondary school class, and it focused on the different types of oral responses students give each other. In addition, the study investigated in what way the students experience this type of peer review. The results show that students reflect on form and performance as well as content, but they place more emphasis on form and performance than content. Students are positive about peer review and its importance for their progress.

Modern missiles must meet higher and higher demands. They should be autonomous, have long range and still have a big effect on the target. To maximize effect on target some missiles not only minimize miss distance, but also try to hit with a certain angle; often perpendicular to the surface of the target. In this thesis a method to guide the missile in the terminal phase of its mission where both point of impact as angle of impact are specified. The method consist of two parts.

The Private Equity industry has over the past years been booming and major external environmental changes have made the industry transform rapidly. Increased competition between Private Equity firms is one of the reasons why the industry has been and is being forced to focus more on addition of value through increased operational management. Consequently, the focus of value addition is by some said to be transferred away from deal making and financial skills, and into active operative management. This case study investigates how the portfolio management, and more specifically the measuring and management of performance, is carried out in a number of leading Swedish Private Equity funds with investments in the biotech sector. The biotech sector is characterized by extensive research and development, and many biotech companies often lack income and other measurable financial parameters in the initial phase.
