Utvärdering av Near Field Communication och Certified Wireless USB : Säkerhet vid utveckling av applikationer

Today?s society is one where technological advances are made daily, which increases the need to stop and assess the risks against users? integrity when integrating new technology in contemporary systems all the greater. We have taken two technologies, Near Field Communication and Certified Wireless USB, whose envisioned area of use is to be integrated into mobile phones, and evaluated what security threats are revealed for the respective technologies. The threats against security have been identified through research of the standards and existing reports for each technology. Practical experiments have not been conducted on account of us not having access to any equipment to run such trials.

Dual coding hypothesis : en empirisk studie kring hur väl hypotesen fungerar för auditiva stimuli

Denna studie utgår ifrån Paivios dubbelkodningsteori, som kortfattat säger att information bearbetas av två separata symboliska system. Dessa system är det ickeverbala och det verbala systemet vilka är specialiserade på att bearbeta två olika sorters stimulusmaterial: bildlikt och språklikt material. Vidare koncentrerar sig detta arbete på dubbelkodningshypotesen som kan härledas ur teorin. Genom olika minnesexperiment angående bilders och ords konkreta värde kom Paivio fram till att vi bäst minns bilder, därefter konkreta ord och slutligen abstrakta ord. Enligt dubbelkodningshypotesen beror det här på att bilder har störst möjlighet att kodas dubbelt (både ickeverbalt och verbalt).

MIMO kanalmodeler

The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.

Produktspårning med RFID : Konceptutveckling och utvärdering

The aim of this thesis was to investigate the possibility of integrating an item tracking systemwith a monitoring system currently under development at Fifth Generation Technologies (P) Ltd.A literature study of RFID technology and the networks ZigBee and MiWi was done. Based onthe literature study a concept for a distributed system was developed.The concept is to have several RFID readers placed in the area where tracking is to be performedand allow them to communicate with each other through wireless communication. The RFIDreaders shall be able to form zones and filter the data that is forwarded from the zones to theservers and thus perform some of the work that the server would normally have to do. Theconcept has been evaluated by prototype development and testing. The prototype uses an ultrahigh frequency RFID reader and a MiWi network.The test indicated some limitations with the selected technologies.

Sociala medier för Knowledge management : Företags användning av webb 2.0 baserade kollaborationsverktyg för kunskapshantering

Knowledge is today one of the most important resources for an organization to handle. But knowledge can also be difficult for organizations to manage. The internet is still growing and new tools take form that allows users to effectively share information. The purpose of this report was to describe how organizations can make use out of internal social media to facilitate knowledge management processes. Three issues involving mapping, coding and dissemination of knowledge to were produced to answer the thesis. The study was limited to examining the identification, coding and dissemination of knowledge through the internal social media plattformen, IBM Connections. The theoretical framework emphasizes how social networks can promote knowledge sharing, how a knowledge mapping can promote knowledge dissemination and sharing, how knowledge can be stored in data sources and how important interaction is to spread awareness. The theory has been supplemented by descriptions of how the system IBM Connections works. Surveys were conducted on four companies that use IBM Connections as an internal communication plattformen. The four companies were selected to illustrate how they use the plattformen of knowledge management processes and we chose to interview the people who were responsible for the introduction of the plattformen. The study identified several similarities between the different companies and that although there were some technical and cultural recalcitrant units against this new type of system within the organization so favored IBM Connections knowledge in several ways. The built-in search automatic created a map of knowledge through the plattform's user profiles. Saved files and documents could be found even after the employees left the company, which encodes knowledge into the company knowledge resources. The opportunity to interact with one another, often over great distances, favored the sharing of knowledge. A comparison with the theoretical framework provided us with the conclusion that internal social media can be used in several ways to Knowledge management through automated knowledge maps, the ability to store knowledge within the company and to communicate knowledge across functional and geographical boundaries in interactive discussions..

Dags att byta skiva : Paradigmskiftens påverkan på skivbolag

Bakgrund: Musikindustrin har upplevt omvälvande förändringar det senaste decenniet, där skivbolagen har tappat 50 % av sin försäljning sedan år 2000. Minskningen beror till stor del på det teknologiska paradigmskifte som skett i och med digitaliseringens intåg i musikindustrin, ett intåg som förändrat marknadsvillkoren för berörda parter.Syfte: Syftet är att förstå hur marknadsledande företag påverkas och handlar under teknologiska paradigmskiften, med utgångspunkt från skivbolagsindustrin. Vidare ämnar vi undersöka vad skivbolagen har haft för roll inom musikindustrin och hur den ser ut i dag efter digitaliseringens intåg.Metod: Uppsatsen är baserad på fyra intervjuer samt en e-postkorrenspondens med personer som har upplevt industrins utveckling de senaste åren. Som komplement till intervjuerna används sekundärdata.Resultat: Skivbolagen upplevde svårigheter i och med det teknologiska paradigmskifte som digitaliseringen stod för. Skivbolagen har efter ett defensivt beteende där de motverkat förändringen börjat arbeta för att skapa affärsmodeller som är applicerbara på den digitala marknaden.
