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.

Trådlösa Nätverk : säkerhet och GPU

Trådlosa nätverk är av naturen sårbara for avlyssning för att kommunikationen sker med radiovagor. Därfor skyddas trådlosa nätverk med kryptering. WEP var den första krypteringsstandarden som användes av en bredare publik som senare visade sig innehålla flera sårbarheter. Följden blev att krypteringen kunde förbigås på ett par minuter. Därför utvecklades WPA som ett svar till sårbarheterna i WEP.

Småföretags Kommunikationskanaler : till externa resurser

Livskraftiga företag har en förmåga att använda sig av externa resurser för att kunna lösa sina problem där de interna resurserna inte är tillräckliga. Småföretag har inte möjlighet att ha alla resurser själva utan måste specialisera sig för att kunna bli mer konkurrenskraftiga i en ständigt ändrande omvärld.Syftet med denna undersökning är belysa vilka olika kommunikationskanaler småföretag använder sig av och vilka faktorer som påverkar valet när de söker externa resurser. Det teoretiska ramverket består av kommunikationsprocessen och kommunikationskanaler. Kommunikationskanalerna består av nätverk, internet, mässor och reklam.  Denna kvalitativa studie är utförd på småföretag inom metallbearbetningsindustrin.

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.

Varför barn får kontaktperson och kontaktfamilj : En aktstudie om barnens bakgrund och skäl till insats

The aim of this study was to look into why children receive the interventions contact person and contact family. This was done by studying case-files. The main questions were:-       How common is it that there are reasons for the intervention linked to parents and which are the most common?-       How common is it that there are reasons for the intervention and problems linked to children and which are the most common?-       Is there any indication of connections between reasons, age, gender or type of intervention? If so, what are the connections?The main results of this study were that most of the children lived with a single mother, often with a weak social network, and in need of relief. It was more common that reasons were linked to children then parents and the most common reasons indicated a need for an extra adult.

Kraftkabelförläggning i mark : - en studie av produktionsmetoder

The assignment given to us by NCC was to compose a degree project based on ground excavations for power cables. The aim of the study was to examine suitable excavation methods depending on different possible terrain conditions. The amount of previously written material within this subject is nearly non- existent and therefore there is a genuine interest by the NCC to receive a compilation of different production methods. The greater part of this study is based upon interviews with several companies active within this area of expertise. The technique of placing the electricity grid beneath ground for safety is today getting more and more common.

Betydelsen av öppenhet, deltagande och ansvar i utformningen av megaprojekt En analys av policyprocessen kring ESS-projektet mellan 1990-2008

This thesis consists of three parts: one normative, one empirical and one constructive, with the intention to explore the enforcement of accountability in megaprojects.The thesis aims to evaluate the level of accountability in the policy process of the European Spallation Source, ESS between 1990 and 2008. In order to make a comparison possible, a norm is created concerning how a policy process should be designed, with primary focus on openness and participation, to make enforcement of accountability possible. The policy process of the ESS is compared with this norm with the purpose of discovering whether the process contains elements that assure enforcement of accountability. After the comparison is done, it is possible to formulate constructive proposals about how the enforcement of accountability can be improved.The thesis also explores how networks, consisting of actors with particular resources, surrounding the ESS-project affects the form of the policy process, e.g. in shaping the social construction of the aim and purpose of the project.
