Analysis and Evaluation of EndpointSecurity Solutions

The main objective for this degree project was to analyze the Endpoint Security Solutions developed by Cisco, Microsoft and a third minor company solution represented by InfoExpress. The different solutions proposed are Cisco Network Admission Control, Microsoft Network Access Protection and InfoExpress CyberGatekeeper. An explanation of each solution functioning is proposed as well as an analysis of the differences between those solutions. This thesis work also proposes a tutorial for the installation of Cisco Network Admission Control for an easier implementation. The research was done by reading articles on the internet and by experimenting the Cisco Network Admission Control solution. My background knowledge about Cisco routing and ACL was also used. Based on the actual analysis done in this thesis, a conclusion was drawn that all existing solutions are not yet ready for large-scale use in corporate networks. Moreover all solutions are proprietary and incompatible. The future possible standard for Endpoint solution might be driven by Cisco and Microsoft and a rude competition begins between those two giants.

A Unified Load Generator for Geographically Distributed Generation ofNetwork Traffic

During the last decade, the Internet usage has been growing at an enormous rate which has beenaccompanied by the developments of network applications (e.g., video conference, audio/videostreaming, E-learning, E-Commerce and real-time applications) and allows several types ofinformation including data, voice, picture and media streaming. While end-users are demandingvery high quality of service (QoS) from their service providers, network undergoes a complex trafficwhich leads the transmission bottlenecks. Considerable effort has been made to study thecharacteristics and the behavior of the Internet. Simulation modeling of computer networkcongestion is a profitable and effective technique which fulfills the requirements to evaluate theperformance and QoS of networks. To simulate a single congested link, simulation is run with asingle load generator while for a larger simulation with complex traffic, where the nodes are spreadacross different geographical locations generating distributed artificial loads is indispensable. Onesolution is to elaborate a load generation system based on master/slave architecture.

Using ant colonies for solve the multiprocessor task graph scheduling

The problem of scheduling a parallel program presented by a weighted directed acyclic graph (DAG) to the set of homogeneous processors for minimizing the completion time of the program has been extensively studied as academic optimization problem which occurs in optimizing the execution time of parallel algorithm with parallel computer.In this paper, we propose an application of the Ant Colony Optimization (ACO) to a multiprocessor scheduling problem (MPSP). In the MPSP, no preemption is allowed and each operation demands a setup time on the machines. The problem seeks to compose a schedule that minimizes the total completion time.We therefore rely on heuristics to find solutions since solution methods are not feasible for most problems as such. This novel heuristic searching approach to the multiprocessor based on the ACO algorithm a collection of agents cooperate to effectively explore the search space.A computational experiment is conducted on a suit of benchmark application. By comparing our algorithm result obtained to that of previous heuristic algorithm, it is evince that the ACO algorithm exhibits competitive performance with small error ratio.

Influence of hardwood, softwoodand fractionated pulp in a stratifiedthree-layered fine paper : Lövved, barrved och fraktionerad massa ochdess inverkan på ett treskiktat finpapper

Four different trials of stratified three-layered fine paper, of sulphate pulp, were performed to investigate if stratified fine fraction or fibres from birch can improve the properties of a paper compared to a reference sheet. All trials had five different scenarios and each scenario was calendered with different linear load. All sheets had a grammage of 80 g/m2.In the first trial, the paper contained birch, pine and filler of calciumcarbonate (marble), and was manufactured with the pilot paper machine XPM and the stratified headbox Formator at RCF (Stora Enso Research Center in Falun). The furnish consisted of 75% birch and 25% pine.The second trial contained coated sheets with paper from trial one as the base paper. The coating slip contained calciumcarbonate and clay and the amount was approximately 10-12 g/m2.The third trial, also with birch and pine but without filler, was performed at STFI (Skogsindustrins Tekniska Forskningsinstitut in Stockholm) with the laboratory scaled paper machine StratEx and the stratified headbox AQ-vanes. The furnish consisted of 75% birch and 25% pine, except for one scenario which contained of 75% pine and 25% birch.The last trial contained fractionated pulp of birch and pine and was performed at STFI. 50% was fine fraction and 50% was coarse fraction.This test does not show any clear benefits of making stratified sheets of birch and pine when it comes to properties such as bending stiffness, tensile index and surface smoothness. The retention can be improved with birch in the surface plies. It is possible that the formation can be improved with birch in the surface plies and pine in the middle ply. It is also possible that fine fraction in the surface plies and coarse fraction in the middle ply can improve both surface smoothness and bending stiffness. The results in this test are shown with confidence intervals which points out the difficulties of analysing sheets manufactured with a pilot paper machine or a laboratory scaled paper machine.

Analysis of Structure and Tendencies of Qualified Immigrant Workforce on the Swedish Labor Market

The purpose of this paper is to make quantitative and qualitative analysis of foreign citizens who may participate on the Swedish labor market (in text refers to as ‘immigrants’). This research covers the period 1973-2005 and gives prediction figures of immigrant population, age and gender structure, and education attainment in 2010. To cope with data regarding immigrants from different countries, the population was divided into six groups. The main chapter is divided into two parts. The first part specifies division of immigrants into groups by country of origin according to geographical, ethnical, economical and historical criteria. Brief characteristics and geographic position, dynamic and structure description were given for each group; historical review explain rapid changes in immigrant population. Statistical models for description and estimation future population were given. The second part specifies education and qualification level of the immigrants according to international and Swedish standards. Models for estimating age and gender structure, level of education and professional orientation of immigrants in different groups are given. Inferences were made regarding ethnic, gender and education structure of immigrants; the distribution of immigrants among Swedish counties is given. Discussion part presents the results of the research, gives perspectives for the future brief evaluation of the role of immigrants on the Swedish labor market.

Utredning av hylskvaliteter : Investigation of core qualities

Vid framställningen av papper för tryckindustrin som använder rullat papper används olika typer av kartonghylsor. Hylsans uppgift är att bära papperet från pappersbruket till kunden. Vidare är det hylsan som ligger till grund för att papperet skall vara körbart och rullbart i tryckpressen. På bruken och tryckerierna utsätts hylsorna för stora påfrestningar vilket gör att hylskvaliteten är av största vikt. I detta examensarbete har ett antal hylskvaliteter avsedda för pappersindustrin utretts. Utredningen omfattades av att undersöka vilka variationer som existerade i dimension, styrka och fukt hos vissa utvalda hylskvaliteter. Syftet var att påvisa den faktiska kvaliteten hos dessa hylsor och utreda om kraven som finns anvisade för dessa uppfylldes. Vidare mål var att kartlägga existerande lagringsklimat vid pappersbruket som använder hylsorna för att fastställa om förhållandena är acceptabla.

Kartdataimport för fälttillämpning

I dagsläget kan WM-datas Fältmodul i deras MoveITS-system inte hantera kartdata i andra format än Shape. Fältmodulen är en TabletPC som kör operativsystemet Windows XP. Den kan användas för att redigera viss geografisk information som exempelvis skyltpositioner. Fältmodulen används av Stockholms Tekniska kontor för inventering av skyltstolpar.Stockholms Tekniska kontor ska börja leverera sina kartor i GML (Geography Markup Language). Men eftersom WM-datas Fältmodul inte klarar av det formatet skulle det här examensarbetet gå ut på att ta fram komponenter för hantering av det. Då det under examensarbetets gång har varit svårt att få tag i information runt GML har istället en större fokus blivit lagd på MIF (MapInfo Interchange Format). Eftersom det finns andra kommuner som använder MIF finns det intresse från WM-data att det tas fram komponenter även för detta format.Ett stort antal klasser har utvecklats för hantering av MIF-filer. Dessa klasser är helt utvecklade i C# och har gjorts under examensarbetets gång utifrån de specifikationer som finns för formatet från företaget MapInfo. För GML har det tagits fram information som kan ligga till grund för utveckling av komponenter för hantering av det formatet.

Utveckling och analys av en PIC-mikrokontrollers möjligheter att kommunicera via TCP/IP

Sterners Specialfabrik AB tillverkar bland annat mynt- och biljettautomater. För att underlätta felsökning, underhåll, avläsning av statistik med mera på en automat är det lämpligt att detta utförs på en PC över Internet. Det innebär att automaten inte behöver besökas då dessa uppgifter skall utföras. Examensarbetet går ut på att få en PIC mikrokontroller att kommunicera med en användare vid en PC över internet. För detta krävs att en TCP/IP stack implementeras på PICmikrokontrollern. Arbetet ledde till en fungerande demoapplikation som klarar av att kommunicera över TCP/IP. Demoapplikationen innehåller diverse olika funktioner för att demonstrera hur en automat skulle kunna styras och övervakas.

Öppna arenor och slutna rum : några kommunikationskonsulter i Dalarna ser på opinionsbildning

Syftet med denna uppsats är att ta reda på hur lokala kommunikationskonsulter i Falun/Borlänge-regionen ser på opinionsbildning via professionella konsulter. De centrala begrepp som avhandlas är PR, opinionsbildning och lobbying.Den teoretiska ram som omger undersökningen består av de teoribyggen som skapats av Jürgen Habermas, James E. Grunig och Larsåke Larsson. Habermas ställer sig tveksam till den demokratiska nyttan av professionell opinionsbildning, Grunig är mer positiv och Larsson ser både för- och nackdelar med PR-verksamheten. Larssons undersökning av opinionskonsulter från 2005 refereras också.Undersökningen bygger på intervjuer med ett antal kommunikationskonsulter verksamma i Falun och Borlänge. Den lokala marknaden för opinionsbildande uppdrag diskuteras, men också huruvida politiska uppdrag förser byråerna med politisk färg. Huruvida medarbetarnas engagemang är viktigt och hur hög statusen på opinionsbildande uppdrag är ventileras, samt vilka arbetsmetoder som används. Intervjuerna behandlar också förekomsten av lobbying på lokal nivå. Till slut redogör de intervjuade för sin syn på hur opinionsbildning, PR och lobbying via konsulter påverkar demokratin.Under slutsatser diskuteras resultatet i relation till den teoretiska ramen. Att PR- och reklambranscherna alltmer växer samman och att opinionsbildning är ett vanligt inslag i många projekt är ett faktum som också skymtat fram i den teoretiska ramen. Men reklam- och PR-metoder integreras också i politiken, på gott och ont. Följaktligen växer den gråzon som finns mellan de olika typerna av kommunikation och mellan opinionsbildande och icke-opinionsbildande uppdrag. Det försvårar gränsdragning och tydlighet, men skapar nya kreativa möjligheter.Att den ökade användningen av kommunikationskonsulter kanske kan bidra till en orättvis fördel för resursstarka organisationer diskuteras. Ny teknik, t.ex. Internet, kan dock eventuellt vara den motvikt som gör det möjligt även för resurssvaga grupper att höras i det offentliga samtalet. Kommunikation som maktfaktor tas även upp utifrån termer som lobbying och medias dagordningsfunktion.Några aspekter av den outnyttjade potential som PR har ventileras också. PR som metod är en outnyttjad resurs på det lokala planet, något som kan bero både på okunskap hos de lokala kunderna och ett traditionellt arbetssätt hos byråerna. Utifrån intervjusvaren framkommer att både byråerna, deras kunder och media på landsorten skulle gynnas av ett större samarbete.Resultaten av intervjuerna stöder mycket i den teoretiska ramen, medan somligt förkastas. Som sammanfattning kan sägas att opinionsbildning via konsulter kan användas för både gott och ont. Vilket som blir resultatet handlar som oftast om etik, ansvar, öppenhet och professionalitet.ABSTRACTThe primary target for this report is to find out how communication consultants in the region of Falun and Borlänge views the practice of establishing public opinions by using professional public relations consultants. The concepts in focus are PR, the moulding of public opinion and lobbying.The theoretical framework surrounding this report is the writings by Jürgen Habermas, James E. Grunig and Larsåke Larsson. Habermas has doubts as to the democratic use of professional consultants working with public opinions, Grunig has a somewhat more positive approach and Larsson sees both advantages and disadvantages in a democratic sense with the PR industry. Larssons research concerning consultants working with the moulding of public opinions from 2005 is also reviewed. The research is carried out by interviewing some communication consultants working in the Falun /Borlänge- area. The local market for commissions concerning public opinions is discussed, but also if and how political commissions are forcing a political stamp upon the firms engaging in such commissions. The importance of personal commitment in the consultants and the level of prominence commissions concerning public opinion has in the business is discussed, but also which methods is used and preferred. The interviews also deal with the practice of lobbying in the local arena. Finally the participants state their views on how the moulding of public opinion, PR and lobbying effects the democracy. Conclusively, the result is put in relation to the theories earlier mentioned. The public relations market is merging with the advertising business, that is a fact, and establishing public opinion is a common element in a lot of projects. But methods used for advertising and PR are also integrated in the political sphere, for good and bad. That has made the distinction between different kinds of communication harder, thereby enhancing the difficulties of establishing boundaries and achieving clarity. Yet at the same time it facilitates new creative opportunities.The growing use of communication consultants may contribute to unfair advantages for organisations with large economic resources. New technical development though, such as the Internet for example, may prove to simplify communication for groups with lesser economic power. Communication as an aspect of power is being discussed in terms of lobbying and the agenda setting power of media.Some aspects of the unused potential that lies within PR are also in focus in this report. PR as a method is an unused resource in the local market, which can be due to the local clients lack of knowledge but also to the traditional work carried out by the communication firms. The findings of the interviews show that both communication firms, their clients and the local media would benefit from greater cooperation.The theoretical base in this work is mostly supported by the interviews, though a few of the findings does not agree. The moulding of public opinions by professional consultants can be used for both good and bad. What the result will be is, not surprisingly, a question of ethics, responsibility, openness and professionalism.

A web based decision support system for status assessment in advanced parkinson

The purpose of this work is to develop a web based decision support system, based onfuzzy logic, to assess the motor state of Parkinson patients on their performance in onscreenmotor tests in a test battery on a hand computer. A set of well defined rules, basedon an expert’s knowledge, were made to diagnose the current state of the patient. At theend of a period, an overall score is calculated which represents the overall state of thepatient during the period. Acceptability of the rules is based on the absolute differencebetween patient’s own assessment of his condition and the diagnosed state. Anyinconsistency can be tracked by highlighted as an alert in the system. Graphicalpresentation of data aims at enhanced analysis of patient’s state and performancemonitoring by the clinic staff. In general, the system is beneficial for the clinic staff,patients, project managers and researchers.
