Säker grannupptäck i IPv6
The IPv6 protocol offers with some new functions, one of them is auto configuration. With auto configuration it is possible for nodes, i.e. hosts and routers, for automatically associated with IPv6 addresses without manual configuration. Auto configuration it is another protocol as it uses Neighbor Discovery protocol (ND) messages (ND is mandatory in the IPv6 stack). The main purpose of ND is that nodes can discover other nodes on the local link, perform address resolution, check that addresses are unique, and check the reachability with active nodes.There are exactly the same vulnerabilities of IPv6 as IPv4 and is now exception, ND if not properly secured.
Hotbilden i Sverige : En undersökning av den digitala hotbilden mot ett medelstort svenskt företag
Internet and information technology today has a rather obvious role in the activities of companies and organizations. All cash transactions within and between companies is digitized, communication within the company is done via e-mail, sales and marketing is done largely with marketing and ads on the Internet. This has resulted in economic benefits for companies and organizations, and facilitated the work for them. However, this has also led to new threats have emerged. Companies and organizations is well aware that there are numerous threats that comes with using the Internet and Information Technologies but exactly what those threats are for a mid-sized company in Sweden is not clarified anywhere.
Miljöoptimera avfallsindustrin i Sverige : - återvinn restprodukten gips
One of the most common ways to produce heat and electricity in Europe today is by the incineration of waste or combustion of coal. These materials can be very sulfurous and during combustion sulfur dioxide is produced. This is an environmental and health related toxic substance which is why power plants have strict regulations on removing it from the flue gas. Sulfur dioxide is removed from the flue gas by adding a limestone reagent. The sulfur dioxide reacts with the limestone and the synthetic product obtained is ?Flue Gas Desulfurization gypsum?.

Att bygga för böcker ? de nya stadsbiblioteken i Simrishamn och Landskrona
The aim of this study is to describe and analyse the creation and the design of a new public library. In order to concretize this, the study sets out from two examples, the public libraries in Simrishamn and Landskrona. The material used to attain the purpose of the study consists partly of interviews, partly of literature on the subject. To be able to put these two libraries in their historical context, the essay also provides a short overview of the development of public library buildings in Sweden during the 20th century. Another aspect that is discussed is the actual procedure of planning a public library from scratch.
The role and influence of the Architect in industrialized building
An emerging trend within the construction industry is the expectation of the customer to experience and sense the product, maybe even in a customized manner. The latter trend would extend the necessity of incorporating not only function and aesthetics, but also perception and sensation. To meet this trend while at the same time improve the productivity the use of information technology such as BIM and technical platforms has increased in construction projects. Nevertheless, in spite of large investments, the construction industry has not managed to increase the effectiveness and productivity as much as other industries. Evident is that successful use of information technology depend on the integration and collaboration of various experts in a continuous and dynamic process.
Boendepersonalens uppfattningar kring socialt stöd
SummaryIntroductory: Since the mid-90s, the numbers of places in psychiatric inpatient settings have decreased and accommodations for individuals with schizophrenia have become increasingly common. In addition to the basic needs that we humans have, individuals with schizophrenia may be in need of special support. Social support can be seen as a protective factor for maintaining health and the recovery of the individual. Lack of social support has shown to be linked to mental illness. The extent of need and support of individuals with mental disabilities may be such that they live in a special accommodation where such assistance can be provided by staff.
Utfackningsväggar ur lufttäthets- och fuktsäkerhetsperspektiv : En jämförelse mellan platsbyggda och prefabriceradeutfackningsväggar
The swedish national board of housing, Building and Planning,recommends that all stakeholders in the construction industryperform a moisture control design to make sure that the buildingachieves good moisture resistance. Since June 1, 2006 there are nospecific requirements or quantitative values for air leakage.Although the swedish national board of housing does presentrequirement that the building envelope must be sealed so that theclient?s requirements for specific energy consumption and installedelectric power for heating purposes are met. Despite this, studiesfrom SP shows that few buildings meet the client?s requirements inspecific energy, which increases the risk of occurrence ofcondensation-related moisture damage.This study aims to evaluate curtain walls connections from airsecurity and moisture safety.
Ett aktivt beslut att renovera passivt : En ekonomisk jämförelse vid upprustning av miljonprogrammetsflerbostadshus
As a result of increased energy prices more and more energy-efficient homes are coveted. An energy-efficient alternative is passive houses, which is characterized by an extremely well insulated building envelope that recovers the heat without the use of radiators or under floor heating. But a passive house requires a higher investment cost than a conventional building project, since it will require more construction materials, training of construction workers, greater land area, and long construction period. But the lower operating cost expects to pay back the higher cost of investment. We therefore question how profitable a passive house is in relation to houses built according to modern conventional building techniques.The aim of our study is to investigate the viability of passive houses compared to conventional houses.

Verifiering av beräknad energiprestanda för flerbostadshus byggda år 2007-2009
The building industry consumes approximately 40 % of the total energy consumption in Sweden, where the using stage is dominating with 80 %. There is a lot of work in progress to reduce energy use in the building industry, and the demands from authorities regarding energy use increases. As a part of this work Building and planning department of Sweden has established a requirement that has been applied since 2006, and restricts a maximum energy use for buildings.The requirement includes that an energy simulation must be done in advance to demonstrate that it is possible to meet the demands.Reality is however more complex than an energy simulation program, that frequently underestimates the energy use of buildings. The purpose of this thesisis to study and analyse deviations between estimated and actual energy use in modern apartment buildings. The study includes four apartment buildings in Stockholm, Gothenburg and Jönköping that were built in 2007-2009.
Utvärdering av SIEM-produkter
Denna rapport behandlar ett examensarbete med målet att hitta en paketering för resursövervakning i nätverk (NPMD - Network Performance Monitoring & Diagnostics) samt centraliserad logghantering (SIEM - Security Information & Event Management).Arbetet har utförts över fem veckor och bestod av att undersöka vilka produkter som kan vara möjliga att leverera till Ateas kunder genom att ta fram förslag på produkter och sedan utvärdera dessa i en virtuell testmiljö.Efter att två veckor av arbetet passerat beslutades att enbart SIEM-produkter skall utvärderas då vi annars inte kunnat hålla tidsramen på fem veckor. De första två veckorna bestod mestadels av efterforskning av olika produkter baserat på ett antal kriterier.Applikationen ska:? Stödja mallar och regler för Payment Card Industry Data Security Standard (PCI-DSS)? Stödja korrelering av händelser? Ej vara open source eller en hårdvarulösningUnder resterande tre veckor installerades, konfigurerades och utvärderades de produkter som var intressanta för ändamålet. Utvärderingen av produkternas funktioner och egenskaper utfördes i en virtuella miljö. Resultatet av testerna är ett dokument som innehåller information om varje produkts förmågor samt betyg på varje produkt.
Det uppätna monopolet : Initiativ, inflytande och resurser vid planeringen av kvarteret Druvan genom projektet Mitt I City
The purpose of this essay is to examine if the municipality has a real freedom of action to control the use of the land and the shaping of the buildings in a large and prestigious building project.In Karlstad there is now (2006) a large building project in form of a shopping mall. This project is in its final stage of completion and offers me a suitable case to examine. To undertake the purpose of the essay, the following research question is formulated:Do the municipality have a real freedom of action to control the use of the land and the shaping of the buildings in a large and prestigious building project as the Mitt I City project?In an attempt to examine the project and the planning process, three themes are applied. The first theme derives from the hypothesis that the part that initiate the process gets the upper hand as future discussions are taking place in relation to the original ideas.
