Referensmötet och den ickeverbala kommunikationen
This is a qualitative interview study of the importance of the non-verbal communication related to the reference situation at public libraries. The experiences of both librarians and users of the reference service have been explored with regards to non-verbal communication. Eight interviews have been carried out. The results reveal that the users and librarians consider that it is important that the librarian find eye contact as well as give affirmation through nodding and smiling. To demonstrate interest and involvement in the questions through attentive listening is also of great value.
Design comparison between HiperLAN/2 and IEEE802.11a services
This paper is a study and comparison between the two Wireless LAN (WLAN) standards HiperLAN/2 and IEEE 802.11a. WLANs are used instead or together with ordinary LANs to increase mobility in for example an office. HiperLAN/2 is an European standard developed by ETSI and the IEEEs standard is American. A WLAN-card consists roughly of a Medium Access Control (MAC), Physichal layer (PHY) and an antenna. The antenna is the same for the different standards.
TCP/IP i taktiska ad hoc-nät
TCP (Transmission Control Protocol) is a transport protocol designed for the wired Internet. In wireless networks packet losses occur more frequently due to the unreliability of the physical link. The main problem is that TCP treats all losses as congestion, which leads to a lower throughput. Ad hoc networks are multihop wireless networks of mobile nodes, where each node can allow other packets to pass through it. Topology changes often occur and may lead to packet losses and delays, which TCP misinterprets as congestion.
Informationsförmedlaren som kommunikatör
This is a study about the communication interaction in the context of the reference work at some public university-libraries and some private company libraries in Gothenburg and Borås. The primary purpose of the study is to investigate the communication interaction in a library situation. The second purpose is to deepen the knowledge, understanding and to establish what is important in this communication. Focus has been on how the intermediaries communicate and how she or he perceives this communication. The intermediary needs to manage the communication with all the different patrons and different information needs of the patrons.

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.
Fjärrstyrning av videokamera
On some occasions it may be inappropriate with a cameraman behind the camera. In somecases there is no cameraman available or it is a smaller event, like a family celebration, to befilmed. It can also be difficult for a cameraman to shoot from certain angles. One solution forthis kind of situations can be to remotely control the camera movements. There are thosekinds of solutions on the market today but they either address professional filmmakers or thefunctionality is limited, for example by the absence of wireless remote control.This project aims to develop a solution to the problem with absence of wireless remote controland also a solution with more flexibility and less complexity than today?s solutions.
Visualiseringsverktyg för modulärproduktutveckling : En studie om designen och implentationen av ett verktyg som ska effektivisera ett modulärt arbetssätt
Due to a growing interest in communication in today?s society the demand for equipment that is used in communication networks increases while the competition between companies that produce this equipment grows. To meet the increasing demand and at the same time having a competitive product development many companies use some effective product design, such as the modular product design. When a modular product design is used it?s good to compare different module configurations for a certain product and to simplify these comparisons some tool can be used.
Gränslandet mellan hem och förskola : en arena för gästfrihetens kommunikation
The purpose of this master thesis is to examine some pre-school teacher's and parent's perceptions about communication within the pre-school context and how this can be described in terms of conceptual dichotomy.The empirical investigation consists of a qualitative study, where data have been collected by interviewing two focus groups and one single parent.The main theoretical tools which the study uses as its premiss is Derridas' theory of hospitality and Habermas' theory of deliberative dialogues. The study also considers the conception of the intermediate domain as an arena for communication between parents and pre-school teachers, and further more the conception of stereotyping in social and cultural contexts.In order to explore these processes I have used the qualitative method of interpretation; Hermeneutic, also with a narrative approach to the analysis.The results and the analysis of the data show that the interviewed parent and pre-school teachers have a poor sense of knowing how much influence to give to each other. The parents were not satisfied with the level of open communication and how the pre-school teachers share information of the activities..
