DDoS: Ett evolverande fenomen / DDoS: An evolving phenomenon
Internetfenomenet ?Distributed Denial of Service?, förkortat DDoS, beskrivs ofta som ett av de
största hoten mot Internet idag. Genom att utnyttja den grundläggande strukturen i kommunikation
mellan nätverk och datorer kan kriminella blockera och stänga ute webbplatser och -tjänster från
användare, samtidigt som det är mycket svårt för offret och myndigheter att någonsin identifiera
den eller de skyldiga. Enorma globala nätverk av ovetande människors infekterade datorer fjärrstyrs
till att utföra angrepp mot alla sorters organisationer på Internet med olika motiv, som finansiella,
politiska eller för ren vandalism. Syftet med det här arbetet är att göra en dagsaktuell kartläggning
över läget kring DDoS-angrepp och titta på statistik över de mest förekommande angreppstyperna,
och se om den nyare publicerade forskningen kan svara på de pågående och framträdande trender
som kan ses.
Konkursprediktion inom service- och informationsteknikbranschen : En undersökning baserad på Altmans studie 1968
Under de senaste åren finns en ökad uppmärksamhet i att kunna förutspå konkurs och andra former av ekonomiska kriser. Vissa forskare menar att konkursprediktion har varit huvudforskningsämne inom redovisning och finans sedan Altmans studie från 1968. Under åren har flera modeller vuxit fram och tidigare forskning har påvisat att konkurs kan förutspås med en hög grad av tillförlitlighet.Denna uppsats har som utgångspunkt Altmans studie från 1968. 66 företag har undersökts i tre år mellan åren 2000 och 2010, varav hälften av företagen har inlett konkurs och den resterande hälften är så kallade friska företag (ej konkurs). Detta i syfte för att undersöka om Altmans konkurspredektionsmodell Z??-score kan appliceras på svenska företag inom service och informationsteknikbranschen.De 33 friska företagen har jämförts mot de 33 konkursförsatta företagen och sedan sammanslagits för en total procentuell klassificering.Vår studie visar att 14 av 33 konkurssatta företag visar tecken på konkurs ett år innan konkurs inleddes.

Identifiering och reducering av köer i samband med återbesök
Purpose ? The purpose of this thesis is to develop a total cost model for container transports and create a tool that calculates a suitable transport quantity from an economic view, which fulfills the demands on delivery service. To achieve this purpose the following questions will be answered:Which costs are affected by the decision between the two transport alternatives LCL and FCL? How does the decision of sending product LCL or FCL influence the delivery service? How can a tool be constructed to simplify the decision-making process regarding the choice of sending products LCL or FCL? Method ? A total cost model was developed. This model is supported from existing literature.
The Communicating Home - Definition, Evaluation and Business Opportunities for TeliaSonera in a 3-5 years perspective
The communicating home concept has been defined byidentifying the dominating communication technologiesto/from and in the homes, the most important customerbehavior and user needs, the dominating products and thedominating actors of the industry.The evaluation of the communicating home industry has beenperformed with a five forces framework analysis and theoriesregarding value migration and value structures of industries. Ithas been concluded that actors of communication technologies,goods and access services will compete fiercely. The barriersof entry will however be high. When it comes to contentservices the situation is completely different. These actors will,to the largest extent, meet lower competition and low barriersof entry.
"Challenges when implementing standardized and processes within a customer service unit"
Abstract Interest in Lean grows and spreads to the public from industrial and service sectors. Lean is currently used in administrative processes and it is called Administration but can administration be Lean? The aim of our study is to develop a useful model for a successful implementation of Lean Administration by using various scientific articles, books and information from the case study.The part of the purpose is to: ? Identify critical success factors that arise? Identify the challenges arising from the implementation of Lean Administration.We have studied a Division within Distribution at GE Healthcare in Uppsala. The model that we have developed provides challenges and success factors for a successful implementation.In order to succeed in implementation, a culture that promotes continuous improvement must exist in the organization. A key success factor is to understand Lean Administrations structure and principles.
När barn behöver stöd i skolan : Direkta och indirekta målformuleringar

As theoretical toolswere used discourse analysis and interpretive policy analysis. The concept ofalienation as it appears throughout Foucault?s work was also used to understand howdifferent knowledge fields as education, special education, psychology and medicinedivide themselves from each other.

Det goda mötet
Måltidskunskap är ett relativt nytt och outforskat området. Forskare menar att måltiden är en diffus sak att undersöka och att det krävs mer djupgående forskning kring ämnet. Den nordiska forskning som gjorts delar upp måltiden i fem aspekter. En av dessa aspekter är mötet. Mötet är en stor del i gästens helhetsupplevelse då det är där all kontakt med personalen sker.
Från produkt till prenumerationstjänst
The use of subscription services directed towards customers has become a common phenomenon in a vast number of different industries. We have noticed a clear trend of new businesses emerging solely offering subscriptions, and existing companies altering sales of their products to become parts of subscriptions. But research has not caught up with this trend yet, especially regarding why it occurs and how it affects existing businesses internally. The purpose of this study is to examine the driving forces for change and examine how existing businesses have to change parts of their business models to offer subscription services. The premise of this study has been Vargo & Luschs (2004) Service Dominant Logic with their foundational premises and Business Model Canvas by Osterwalder et.
Internetbegränsning på stadsbibliotek
The purpose of this thesis is to investigate how city librariesmaintain the intellectual freedom in their Internet service. Thediscussion about Internet filters has been quiet in Sweden forseveral years, so I wanted to see if there had been an increased useof filters. I also wanted to see if the city libraries regulated theInternet service in another way. I sent a survey to 100 libraries andgot answer from 83. To explain what intellectual freedom is, I usedStuart Hamilton?s theory about intellectual freedom in the librarycontext.
Den demokratiska lyxen
Abstract: The fashion industry is perhaps the most unpredictable one where change occurs very rapidly. In order to be attractive and interesting in this competitive industry, a brand must constantly be up to date and differentiated from other brands to attract the consumers. This has given rise to an increasing growth of brands that cooperate for marketing reasons and more specifically, clothing retailers that perform designer collaborations with exclusive designers to create limited collections.Studies describing the effects of those collaborations on the retailers brands are rare and especially from a consumer perspective. Since H&M has been a pioneer in designer collaborations and has done it more times and for more years than any other retailer we have conducted our study on their case. Our intention was to investigate how the designer collaborations have affected the brand equity and image of H&M, if the collaborations have increased the willingness to pay for H&M's other ranges and if they have affected H&M's ability to extend its brand to higher price segments, through an experimental study.
Ersättningsmodeller för ballasttransporter : vid anläggning och underhåll av skogsbilvägar
