AUTOMATISK PAN/TILT-KONTROLLER FÖR ANTENNINRIKTNING

This report describes the design and construction of a prototype that automatically aims a microwave link towards a target. The link, that is located on a mobile aerial mast, is used by Saab Training Systems as a part of an infrastructure network. The report also discusses the development of a GUI that communicates with the control unit by Bluetooth.The control unit, called Pan/Tilt-controller, controls the position of the link by stepping motors. One motor controls the azimuth angle and the other one controls the elevation angle.By a GUI the operator enters the coordinates on its own position and the targets position. Hereafter a bearing is calculated and it will be sent up to the control unit.The control unit will sense its own direction by a magnetic sensor that works as an electronic compass.

 Unga föräldrar :  En kvalitativ studie om ungt föräldraskap sett utifrån professionellas perspektiv

The purpose of this paper was to examine how young parenthood is represented by the professionals and their thoughts and experiences from meetings with the young parents, and how the professionals work with this group of parents. As professionals we refer to those who work with young parents, and the definition of young parents are parents in the ages 15-24. The paper also discusses what needs these parents have, and what kind of support the society offers, according to the professionals. The method we worked with was interviews and we interviewed six professionals to find out how the professionals looked upon the young parents and their situation. Earlier research has stated that young parenthood is associated with many risks and disadvantages for both the parents and their children.

Barn till alkoholmissbrukare : en studie av barnens uppväxtvillkor och det sociala nätverkets betydelse

Our purpose with this paper was to examine what effect a parent's drinking problem can have for the children in the family. A combination of literature study and qualitative interview analysis was used. The most important research questions were: How do the parent's problems affect the child? In what ways can the social network around the child help it to develop normally despite problems in the home environment? To what extent a parent's drinking problem affects a child depends on many different factors. Based on earlier research and interview data we drew the conclusion that growing up in a family where a parent has a drinking problem has a negative effect on all children.

Ledningsstrukturer inom terroristorganisationer - En fallstudie om ISIS

Since events of September 11 and the subsequent conflicts surrounding the event, the war against terrorism has been constantly present. It has been used several methods and strategies to address these threats, including a method current in use, the targeting method. The method refers to use few but precise attacks to knock out key functions within these organizations, mostly individuals in the higher command and control structures within these organizations. The effectiveness of the method has been put in question when the majority of the terrorist organizations continue their strife, in some cases even increasing its intensity. The purpose of this study is to investigate which role the higher command plays in these organizations ability to wage war.

Nulägesanalys och verifiering av autentiseringsmetoder : En studie på ett konsultbolag i nätverksbranschen

This report is written for a consultant networking company with the purpose to review the development ofthe company's remote connections from a user friendly and security perspective.This includes an investigation of the possibilities to consolidate existing authentication methods foraccessing customers. The problem lies in the amount of methods being used. Through case study wefound that smart cards, SMS-service, software and hardware tokens exist.The only method feasible from a security perspective is smart cards. Since the method is not commonlyused by the company's customers a standardization of it would be counterproductive.Also, the purpose of this report is to investigate how the ongoing internal development of the remoteconnection will affect the company's clients. Within this framework we have also verified a designsuggestion.We interpret, after the completion of the case study, that the internal development of the remoteconnection is marginally affected by legal perspectives.

Socialtjänstens stöd till familjehem ur utvecklingsekologiskt perspektiv - Fallet Linnéa -

The aim of this essay was to investigate how social workers, within chosen Social services districts in the northwest of Skåne, work with children placed in foster care. Our purpose was to investigate the interaction between the child and the foster home from the perspective of the Ecology of Human Development. Our questions were:* How do the social worker prepare the child and the foster home before a placement?* What kind of support is offered to the foster home with the purpose of supporting the child?* How do the social worker make the childs contact with the biological parents easier?* To what degree does the social worker work on strengthening the child's network?* Which factors do the social worker decide the allocation of support?* What do the social worker think affects the work with the foster home from a society level?To answer our question we have interviewed nine social workers. We found that the social workers were generally good at perceiving how the micro- and meso-systems, and to a certain extent the exo-system, influenced the foster child.

Massundanträngning i samband med pålning i lera

Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

Det viktiga mötet: En studie av intern interaktion i företagsinkubatorer

Entrepreneurship is considered essential for the Swedish economy, as well as globally. Accordingly,massive efforts are put into creating environments that successfully can support new ventures. The business incubator is a prominent part of these efforts and is important especially for the knowledge shared within its internal network. The aim of this study is to further explore how different activitieswithin the incubator can influence the interaction, and thereby the construction of social capital,among the incubatees. Using a qualitative case study of three incubators, and the framework of theincubator model, it is concluded that three distinguishing components within the framework influence the interaction, namely infrastructure, mediation and business support.

Resurseffektivt bussprotokoll o?ver RS-485

This report describes the design and implementation of a multi-master, packet based protocol for small and tiny microcontrollers where resources are limited. The protocol was named "Tiny Controller Network" or TCN for short. The protocol is meant mainly as a control bus for automation and sensor acquisition applications but due to its flexibility can also be used for other purposes as well. It borrows some of its functionality and design ideas from the well known CAN bus and Modbus but also has a number of major differences like the use of standard hardware and time synchronisation. One of the key aspects during the design was the use of very little system resources and common on-chip hardware peripherals like a UART.
