The purpose of this thesis is to investigate the possibility to make small, cheap and ultra low power sensor platforms, connected in wireless networks for monitoring of home and industrial environments. The concept is based on ideas from our supervisor, Jerry Lindblom. The developed system consists of a generic platform for different sensors, a receiver and software. A GPRS module from RO Rollytech AB and a database from Gema Industri AB have been modified and used to demonstrate an example of a complete system. To the platform, it is possible to connect any resistive sensor and any sensor that can act as a switch.

The Center for Genomics and Bioinformatics (CGB) is an academic department at Karolinska Institute. Generally stated, the CGB department is committed to the generation and management of genetic information by approaches aiming at elucidating the connection between genes, protein and function.WiGID is a genome information database that is available through WAP (Wireless Application Protocol).Our version of WiGID is based on WML, PHP and PostgreSQL as a database server.One of the changes on the old WiGID application was the creation of a relational database with seven tables and one view, instead of the file that represented the database on the old version. We also changed the script language from python to PHP.The search engine ability has been extended with three new search alternatives for a user to choose from. Each choice leads to other, sometimes multiple choices.A GUI has been created for the administrator, to be able to insert information into the database.The structure of the search engine is primarily for narrowing down the search result on the phone display, thereby making the search efficient..

Denna studie tacklar ett av de problem som modern IP-telefoni brottas med, som gör att det är svårare att konkurrera med traditionell telefoni: fördröjningar på grund av otillräckliga Session Initiation Protocol-servrar (SIP). Genom tester av de viktigaste faktorerna jämförs fyra högaktuella Open Source SIP-servrar: OpenSIPS, Kamailio, FreeSWITCH och Yate. Avsikten är att underlätta valet av SIP-server för nya applikationer inom IP-telefoni, öka prestandan samt snabba på utvecklingen. Studien behandlar de intressantaste faktorerna vid val SIP, såsom användarvänlighet, hastighet, lagring av användardata samt ljudkvalité. Slutsatsen blev att Kamailio stod som klar segrare, med överlägsna resultat i jämförelse med övriga servrar, på de parametrar som valts ut.

Detta arbete handlar om nätverksfilsystemsprotokollen SMB/CIFS, SMB2 och NFSv3. Arbetet baseras på artikeln ?A New Network File System is Born: Comparison of SMB2, CIFS, and NFS? som skrivits av Steven M. French på IBM, Samba Team. I den artikeln saknas det prestandatester och därför känns det relevant att göra prestandatester för att få fram vilket protokoll som har högst hastighet med olika filstorlekar i Windowsmiljö.

The use of fossil fuels such as coal and gas are a contributor to the global warming. The climate change is a worldwide problem with far reaching consequences that is believed to be very expensive. The United Nations has been introducing a framework convention on climate change. One component of the convention is the Kyoto protocol. The protocol is obligating the developed countries to decrease their emissions of greenhouse gases by 5.2 percent during the time period 2008-2012.

Lansen Technology develops and sells alarm systems. The communication between the system devices are wireless. The radio protocol used by the system is developed by Lansen with the purpose to be energy efficient. The alarm systems target groups are individuals, businesses and government agencies. The current system is installed, configured and controlled from a control panel for all audiences.

Development and accuracy tests of advanced exchange trading systems require well adjusted tools for testing. Aptness of these tools are probable to have a major impact on identification of bugs and verification of new functionality. Identifying erroneous parts and bottlenecks of the trading system is of outmost importance for the exchange as a whole since stability and correctness are two of the determinant factors its viability is measured by. This paper covers how this test-tool was created and the motivation behind the design choices made. The tool was created with the goal to be broad enough to cover the majority of cases that could arise, fast enough to be able to test the trading systems speed limitations (i.e.

This report describes the construction and development of a control box, which is a tool for testing and verifying a certain model of Rapid?s built in staplers (model A6102). Basically the function of the control box is to interpret any errors that may occur in the stapler and to make it possible to test fire the stapler.The control box should be able to communicate with the stapler using a specialized communication protocol. The different data such as errors, firmware etc. from the stapler is presented in plain language on a display.

Abstract  This paper examines the Copenhagen Climate Conference held in the Bella Center in Copenhagen, December 2009. The aim of this paper was to analyse the highly anticipated conference, and why it did not result in a binding protocol between the world?s states. The focus of this paper was to examine two key actors in the Copenhagen negotiations: the people?s republic of China and the European Union.

Opioids are considered the "golden standard" in pain management for both humans and small animals, but is used less often in equine medicine - probably for fear of side effects. Are there any studies that suggest that side effects are a major problem, or is it lack of experience which is the greatest obstacle to use? As early as 1937 it was shown that morphine and morphine derivatives provide analgesia in horses. For species other than horses used opioids often both pre-, intra-and postoperatively. They relieve pain effectively and are often included in the anesthesia protocol.

Climate change is one of the most difficult problems that humans have to deal with. Today, the evidence of human effects on the climate change and the rise of temperature on earth are strong. It is extremely important that all countries get together and cooperate in order to be able to solve the problem with climate change. One step in the work on climate changes is the Convention on Climate Change, which was agreed on in 1992. The Convention on Climate Change resulted in the Kyoto Protocol in 1997. The Kyoto Protocol is an agreement between a number of industrialized countries to limit or reduce the green gas emissions.

Den 21 januari 2011 delades de sista tillgängliga blocken av IPv4-adresser ut. Detta gör att dess efterträdare IPv6 är aktuellare än någonsin, då det snart inte finns några adresser kvar. IPv6 för med sig mer inbyggd säkerhet, men också nya säkerhetsrisker. Detta arbete undersöker vilka säkerhetsrisker gällande tillgänglighet som finns vid en övergång från IPv4 till IPv6 och vilken medvetenhet systemadministratörer har om dessa. Resultaten tyder på att det finns en mängd olika säkerhetsrisker vid övergången till IPv6.

Every year more than 6000 thefts, to a value of 1.5 billion SEK, are reportedwithin the Swedish building trade. Plus all the indirect costs of having theconstruction site standing still.SafeTool is a newly started company that will try to prevent this problem witha modern technology solution.The key to SafeTool?s solution is RFID ? Radio Frequency Identification ? andthe solution looks like this;All tools are stored in a container on the construction site. Every tool isequipped with a RFID-tag that uniquely identifies the tool. With antennas in thecontainer it is possible to detect when a tool is leaving the container and whenit comes back.

Traumatic deaths hit relatives hard and a fast and professional encounter can make crisis management easier. The purpose of this literature review is to find partly how relatives after traumatic deaths are taken care of and how nursing staff fulfil the relatives' needs and also how nurses prepare themselves before this encounter with the realatives. The method in this study consists of a literature review. This was done through critical examining a number of articles within this area. The result shows how a nurse could encounter relatives after traumatic deaths.
