Distribuerade fastighetsautomationssystem : - En implementation av kommunikationsprotokollet BACnet

Building Automation Systems in commercial buildings are often designed and installed by different contractors, using equipment and components from different manufacturers. The lack of an accepted communication standard has resulted in a few different standards. Many manufacturers of building automation systems only support one, a few or none of these standards, while developing proprietary system solutions. Regin, who develop such equipment, are planning to adopt an open communication protocol specially designed for building automation - BACnet. As a step in that direction this thesis was announced with the purpose to investigate the possibility to implement BACnet in one of their products and to gain more knowledge of the BACnet protocol.

XML som informationsbärare för EDI

Information handling has been a key issue for different companies for a long time. Electronic Data Interchange (EDI) is used to transfer different business documents from one company to another. This is done in such way that the information itself is separated from how this information is stored and handled in the companies internal systems. As different companies have different systems there is a need for a standardised format for this exchange. There is a big difference between EDI-systems based on what kind of EDI-standard is used.

Karriärist javisst! : En kvalitativ studie om fäders upplevelser kring vård av barn

Utveckling av högspänningskontakt

This report describes the development of a high-voltage connector at the request of Scandinova Systems AB in Uppsala. The development process is described from the making of a customer demand specification, to the making of drawings for the manufacturing of prototypes. Scandinova develops high-voltage modulators, hence the need for connectors that can handle very large power pulses. Their current connector has several weaknesses that may cause the connector to melt or catch fire. The development began with a number of studies that included the modulator structure and the current connector structure and functions.

?På resande fot? - En studie om hur individer stöds och upplever mobilitet i sitt yrkesliv

The use of information technology (IT) has expanded to be available in large parts of the society.With reference to this mobility has become an increasingly used term, which reflects changes in our lifestyle, travelling and mobile artefacts. The technology development that has occurred in recent decades has made it possible for people today to be more mobile than before as they no longer are tied to a fixed workplace. Mobility has changed the ways to lead, coordinate andmeasure work productivity in organizations. It has also added new ways of working. The mobile development also means more challenges and changes in today?s modern organizations.The purpose of this paper is to analyse how employees in a consulting form use mobile technology in a work context, how they interact with others and how individuals reason about mobility.

Smart plombering och märkning

The background for this degree thesis is a need to replace the existing seal used to protect equipment containing secret or sensitive equipment used by Swedish Defence. The target design should satisfy both the need for tamper evidence and reduce Life Cycle Cost. In developing a new design for a seal, additional benefits such as improved logistics support and indication of attack methods such as heat and solvents have been considered.The lack of guiding principles for end users of seals became evident during the interviews. Major concerns for the future are education of users, information about actions if a seal is broken and user liability.The design work was divided into several phases. A feasibility study was performed including investigation of theory of labels, materials and possible technologies.

Underhållsfria material i broöverbyggnader : Fördelar ur kostnads- och miljösynpunkt vid användning av rostfritt stål och direktgjuten betong

En stor del av Trafikverkets budget går till att reparera och underhålla våra broar. Underhållsåtgärder orsakar också trafikproblem med stora miljöutsläpp och samhällskonsekvenser som följd. Eftersom broar vanligtvis dimensioneras för en lång livslängd på 120 år är det viktigt att planera för långsiktiga lösningar och förutse konsekvenserna av kommande underhållsåtgärder. Genom att använda mer underhållsfria material finns möjligheten att minska kostnaderna och koldioxidsläppen.Målet med examensarbetet är att ta reda på hur stora besparingarna är genom att svara på frågan: ?Vilka fördelar erhålls av att använda mer underhållsfria material i broöverbyggnader ur kostnads- och miljösynpunkt??.

Reproductive physiology of the female cat

The cat is one of our most common pets. Understanding the reproductive physiology of the queen is important, not only for the knowledge of our domestic cats but also for wild undomesticated feline species, many of which have been reported endangered. Understanding the mechanisms behind the estrous cycle, ovulation and pregnancy is also important for handling the feral cat populations that are a problem in several countries. The purpose of this literature study is to look into the hormonal patterns of the reproductive physiology of the female cat, with focus on ovulation, pregnancy and pseudo-pregnancy, and from this information determine in which fields more research would be needed. The female cat is seasonally polyestrous in Sweden, meaning that she can have several estrous cycles during the breeding season but goes through a long period of reproductive dormancy during the darker months of the year. The queen is considered an induced ovulator, with copulation triggering the release of luteinizing hormone (LH) from the pituitary gland needed for ovulation.
