A current conveyor is an active building block that can be used to implement most active and passive components. It differs from the operation amplifier in that it uses current instead of voltage. The current conveyor also has significantly higher voltage gain over a broader frequency range. To simplify the construction of analogue circuits and increase the construction efficiency it is desirable to use a top-down methodology. This means that the whole system is partitioned into a hierarchy of subsystems.

Companies acquiring ERP systems are often dissatisfied with the project and therefore consultancy firms wish to make use of project models in order to achieve success in implementations. Since research on ERP implementations in service companies is limited, there is a need for mapping of critical activities in implementation projects in this line of business. Under these premises, the purpose of our master thesis is to develop a model for implementation of ERP systems, specified in activities, which can be used by mid-sized consultancy firms with mid-sized qualified service companies as customers.A literature study including project models, modern models and methodologies for ERP implementation, commonly existent activities, success factors and system development methods was carried out. Starting out with this, a theoretical model for ERP implementation was generated. In excess of this, a case study was conducted, where the implementation of the ERP system Microsoft Dynamics AX at the service company Eurostep, performed by the consultancy firm Medius, was studied.

The river Göta Älv reaches between Vänern and Gothenburg and is the main raw water source for Gothenburg that supplies about 700 000 people with water. To protect and maintain a high water quality, continuously samples and water analyses are made throughout the river. In 1998 a protection area was founded between surte and Lärjeholm where the raw water intake is. This was made to increase the awareness of the importance to protect the water. However, there is a lot of contribution of untreated stormwater to Göta Älv within the protection area.Göteborg Water and Sewage Works commissioned this thesis where two areas, Tagene industrial area and Kärra residential area, with untreated stormwater outlets within the protection area are studied.

This is an explorative study about subject indexing of a special collection of books, administered by the John Andrén Foundation at the library of Ystad. The study summarises a number of theoretical perspectives as well as some practical instructions on how to carry out the task. Theories have been placed into five different groups according to their various approaches to subject indexing. These have been analysed in regard to their usefulness to the Andrén collection. The authors have tested and evaluated six practical models on a selection of books from the Andrén collection.

Since product placement is a relatively new phenomenon in Swedish television, there is a lack of research on what attitudes Swedish TV-viewers hold towards it. This is where our paper will contribute to the research. The purpose of this reserachpaper is to describe and analyze what attitude Swedish TV-viewers has towards product placement. Kim Schröders multidimensional model of mass media reception were used, which is a developed model from Stuart Hall?s ?encoding/decoding? one-dimensional model.

Testing has always been an important task in the scope of software quality. Though it has never been as much appreciated within the management of the organisations as the software development has. However testing is becoming more attractive within organisations because it becomes more evident how much money working systems saves in contrast to defect ones. A tester often use testing tools to simplify the work progress. There are a lot of tools nowadays but not many evaluating models which helps the tester to know which one to recommend.

In this study, the pre-tension force in an insert screw connection are examined in order to establish a greater understanding of the system and to facilitate the process of making new metal cutting tools. Certain especially significant design variables such as the offset, the length of the contact thread and the shank length above the threaded hole, are selected to be closely examined. A comparison of the influence on the pre-tension force between threaded holes made with a worn, versus new, threading tool is also involved in the experiment. The study is limited to handling the screw sizes M2,5 and M3,5. The results show that a regression model, with good approximation, can be fitted to the measured values.

The name of the study means ?The short arm - a study in diversity and arm?s length in the cultural collaboration model?. Right now there is a reform in the Swedish cultural administration where the responsibility for handing out state funds and grants to cultural organizations is changing from the state government to the local regional governments. The purpose of this study is to map the organisational changes caused by the reform and investigate how this affects the regional policies concerning cultural diversity and the arm?s length principle.

Hospital Mergers have been proved to be troublesome, the most crucial ingredient is believed tobe the participation of members of the organization on all levels. When the hospital mergerbetween the hospital of Malmö and the hospital of Lund is a fact, it seems clear that knowledgeabout managing motivation is important. The knowledge could also lead to increased possibilitiesto improve support for motivation where needed at the hospital.I have through a literature review created a descriptive model of the theoretical view onmotivational factors for participation in change and their relationships. The theoretical modelwhere then tested in a empirical study in which additional data created a more true model of themotivation on participation at the hospital.The findings of the study show how the descriptive model illustrates how the twodifferent departments both work with a empowering philosophy that have built in properties thatenable the employees to gain more motivation. The model also underline the importance of thecommunication role to enlighten the employee in what, where, when and why the change takesplace.

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

Sitka spruce (Picea sitchensis) is not considered to be a native species to Swedish forests. It´s origin is the pacific coast of Northern America, an area that is dominated by a coastal climate which makes it likely to believe that it would be well suited for growing in the south-west of Sweden. This study aims to investigate the gain in production that can be reached by growing sitka spruce instead of Norway spruce (Picea abies) in the county of Halland. A regression model based on data from forest experiments was produced to explain the gain in production. This model was based on elevation and annual precipitation. The model was then used to create a map layer in arcGIS that shows the gain of volume in comparison to Norway spruce in percent. An analysis was carried out to find what share of the forestland in Halland county that fell into four different classes of production gain.

Two of Swedens´s major banks, SEB and Handelsbanken, which appears in the same industry and have similar strategy. Both banks can achieve a similar result despite the fact that their reward system looks quite different. An issue that arises from this observation is the relative reward system to the rest of the economy control system.Our purpose of this paper is therefore to examine the reward system in the organization's financial management systems. We wonder if the reward system may be a function of economic control system, or part of the system, or perhaps made independent of the system and then gradually adapted?In our study, we choose to assume a reward system has three functions to manage, motivate and compose the employee group.

Abstract The purpose of writing this thesis was to improve methods during requirements engineering phase. Usercentred system engineering has some problem areas, which are examined and verified to create a new guideline for developers. This guideline tends to make requirements engineering more effective and help developers create more concrete requirements. It is not uncommon that system development projects ends up with unsatisfied users or delay in deliveries. The reasons are different kinds of communication problems between users and developers during verification of requirements. There is a therapy model, called solution-focused therapy, used in family and individual therapy. The model focuses on solutions for the future instead of problems in the past.

The Swedish consumption of lamb a increasing, and today we yearly eat a kilo of lamb per person each year. As a consequence the Swedish degree of self production according to lamb is steadily decreasing, and is today about 39 %.Today Swedish Meats is now cooperating with the Swedish lamb breeders organisation to raise that percentage. At the same time the European Union presents a new agricultural reform, the MTR (Mid Term Review). The shape of this new reform is not yet fully known, but the general policy has been more or less outlined. The new reform is split into three propositions: the farm model, the regional model and the mixed model.

Background: It has been shown that companies that lived under protected conditions for a long time have had difficulties to adapt to major changes. With that in mind an even more extensive low-cost competition in the Swedish grocery market will make a threat for the traditional grocery stores' long-term survival. The question then becomes, which strategies will be successful and lead to higher customer loyalty.Problem: Are the traditional grocery stores using strategies that can compete in addition to pricing and will those strategies lead to long-term survival?Objective: Is to analyse and evaluate two traditional grocery stores' strategies and to examine whether these are consistent with customer demand.Approach: First we have created a more fundamental understanding of the situation in the Swedish grocery market. Then we have implemented two interviews in each grocery store.
