Industrivatten : ett gestaltningsförslag över det Östra årummet i Gävle
A proposal of a new path from the inner town of Gävle to a small cultural area in the seaside. The thesis contains historical background, analysis over town and the area, and a proposal of a new shape for the postindustrial area near the stream called Gavleån. .
Undersökning av mätsystem och regulatorstrukturer för industriella tillämpningar
This thesis is divided in to two different parts. The first part includes examination of the measurementsystem of an industrial robot using a resolver sensor. The main focus is on methods for suppressing noise in the angularvelocity signal without increasing timedelay. Five different methods are investigated. Three of these are based on oversampling: burstsamplingmethod, meanvaluemethod and correlationmethod.
Överföring av och beräkning med timmätta värden ? från MT2000 till Xpower
New technology makes it possible to remotely measure all consumers in a power network onan hourly basis and store the values in a database.This thesis work describes the conversion process between automatic meter reading systemMActor and calculation software Xpower.Then the possible differences between calculations of power networks using load curves incombination with a yearly estimate of consumption and calculations using hourly measuredvalues is examined.The result of the comparison shows that, for the power network under inspection, nosignificant difference could be noticed. This does not mean that calculations using hourlymeasured values would be unnecessary. I believe that in a near future calculations using hourmeasurements will be the primary choice for many power companies to whom technology isavailable.Also some basic calculations of fundamental power network parameters, such as power factorand loses, are presented using hourly measured distribution transformers in combinations withits hourly measured loads.The report is written in Swedish.
Lågtempererad fjärrvärme i Umeå
People in today?s society are becoming more and more aware of how important it is to use energy as efficiently as possible. This is clearly noticeable by an increase in home produced heat with e.g. solar panels or heat pumps heating systems. These changing customer demands forces district heating technology to be redesigned, which is why there is an ongoing research regarding the next generation of district heating - low temperature district heating (LTDH).
Resurseffektivt bussprotokoll o?ver RS-485
This report describes the design and implementation of a multi-master, packet based protocol for small and tiny microcontrollers where resources are limited. The protocol was named "Tiny Controller Network" or TCN for short. The protocol is meant mainly as a control bus for automation and sensor acquisition applications but due to its flexibility can also be used for other purposes as well. It borrows some of its functionality and design ideas from the well known CAN bus and Modbus but also has a number of major differences like the use of standard hardware and time synchronisation. One of the key aspects during the design was the use of very little system resources and common on-chip hardware peripherals like a UART.
Muddring i Ireån : indirekta effekter på bottenfaunan nedströms
This research aims to investigate the effects that dredging may have on benthic fauna. The dredging took place in the stream Ireån on northern Gotland during the early summer 2010. My area of research was taking place in a scenic area downstream in Ireån close to the Baltic Sea. I chose this area due to the dredging that started just upstream of this area and continued further upstream. Thus it is not the direct impact of the dredging that is the focus for this paper but the side-effect the dredging may have on the area downstream.
Segmentering av lokala nätverk - För mikro- och småorganisationer
Syftet med den här rapporten är att beskriva ett antal olika tillvägagångssätt man kan använda sig av då man har behov av att dela in ett lokalt nätverk i olika segment och med det även kunna reglera trafikflödet mellan segmenten. De lösningar som presenteras i arbetet är inriktade mot mikro- och småföretag.Anledningen till att vi har valt att arbeta med det här området är att vi anser att det är viktigt för organisationer att har en strukturerad och segmenterad design på sitt interna datornätverk.Vi har arbetat genom att i förväg samla in information om olika tekniker som kan tänkas lösa vårt problem, och därefter testat olika scenarion med dessa tekniker. Data har samlats in efter varje genomfört scenario och sammanställts i statistisk form för att kunna avgöra vilken metod som var att föredra.Vi har testat lösningar där man segmenterar nätverket i en lager 2-switch medan man möjliggör och förhindrar trafikflöde mellan segmenten i en router. Även lösningar där man använder en lager 3-switch har testats. På så sätt kan routningen ske direkt i switchen och det blir betydligt mindre belastning i routern.

Kommunikationslösningar i molnet : Examensarbete angående olika nätverkslösningar i WAN
Att koppla samman nätverk över geografiskt olika platser har blivit allt vanligare i dagens samhälle. Rapporten kommer belysa olika WAN-lösningar för att göra detta möjligt. De olika lösningar som kommer belysas i denna rapport är att hyra egen fiber, lager2-länk, MPLS och även VPN. Det kommer göras jämförelser mellan dessa lösningar när det gäller kostnad, säkerhet, hastighet och tillförlitlighet. Detta har gjorts med vetenskapliga artiklar och intervjuer men rapporten innefattar även en praktisk tillämpling i form av ett experiment..
"Ett artigt pennekrig" En biografisk studie av Gustaf Montgomerys nätverk och författarskap under en period av ideologisk förändring och nya roller för författare 1812-1842
Studies of networks, fields and of communicative circulations complement each other. This master thesis is a biographical study of an author and journalist, Gustaf Montgomery GM, his network in Sweden of the early 19th century, and a study of his authorship and literary career. The starting-point of the study is GM:s change of field from the conservative to the liberal in 1832. The aim is to give explanations to this change and to describe how the change in turn effected the network. The method used is critical of sources.
VARN Ett nätverksbaserat 2D-actionmultiplayerspel skrivet i Java.
VARN A network multiplayer 2D action game written in Java. All games that support any form of play across networks is in one way or another affected by the delay, or "ping", that occurs from the time it takes for information to travel over the wires. Not only does it take time, it varies depending on how far away the connected partner is and the current status of the network you are on. Through the years a lot of different methods have been developed to combat these delays. I have reviewed some of these methods and implemented a synchronization system in Java meant to be used in online action multiplayer games..
Smarta Hus : Nya behov och lösningar med participativ design
In this Bachelor Thesis (20 p.), we present the history and development of "Intelligent Houses", and most important- explore some of the future possibilities in this area. The project has been carried out through an interdisciplinary cooperation between three different educations at the Blekinge Institute of Technology. By conducting a dialogue with various actors with different professions, we have been trying to identify needs within the concept of "Intelligent Houses", were the end user is not only the tenant or homeowner. Through Participatory Design methods, such as a Future Workshop, we have brought the users together to discuss their own and each others needs and hindrances in their respective work practice, and how intelligent house technology could improve their work conditions. We have also been testing a highly sophisticated CO/CO2/Moisture/Temperature/Enthalpy multi-sensor & controller, originally developed for regulating indoor climate systems.
"Snipp snap snut, nu tog tiden slut" : En analys av användares medvetenhet kring integritet på mobilapplikationer
This study focuses on the integrity of students at Uppsala University that has used the university?s network, UpUnet. We?ve studied their opinions with the use of questionnaires that cover questions related to privacy and awareness about logging of data traffic.The results showed that more students than our hypothesis suggested were unaware of the surveillance on the network, and the majority of these also had a negative opinion towards logging of data traffic. However, we found that there were several relations between how the students responded on our questionnaire, and we?ve presented these in the analysis chapter towards the end of the essay..
Controllerns yrkesroll- Förklarad med hjälp av rollteori ur ett multipelt per-spektiv
Bakgrund: Tidigare forskning och litteratur som behandlar controllerns professionella yrkes-roll beskriver den tekniska rollen, där controllerns administrativa och funktionalistiska roll i organisationen står i fokus. Rollen kan beskrivas vidare med hjälp av sociologisk rollteori där rollskapande och rollåterskapande är två centrala begrepp.Problem: Utifrån tidigare forskning har vi formulerat tre frågor i syfte att förstå controllerns yrkesroll utifrån ett socialt rollperspektiv: Vad betyder begreppet controller och vad säger teori och tidigare forskning att en controller bör göra? Vad är controllerns roll i praktiken och hur skapas yrkesrollen? På vilket sätt går controllerns rollskapande att förklara med hjälp av rollteori?Metod och teori: Vi tillämpade en fenomenologisk tolkande metod i denna studie, då vi valde att fokusera på controllern som individ. Utifrån sociologisk rollteori ur ett multipelt perspektiv analyserar vi rollbegreppet, i syfte att få kunskap om hur individer skapar mening i den värld de lever i. Vi använder oss av tre rollteorier av tre välkända författare inom sociologisk roll-teori för att vidare tolka controllerns roll bortom den tekniska beskrivningen.
Access to the market - a question of collaboration?
When contemplating entering an alliance the rationale behind the decision should differ
depending on the size of the companies involved as well as on other important factors. The important
factors influencing the decision are related to the resource pooling potential of the alliance,
the power structure along with the business network the companies are a part of. The
analysis has shown proof of a need for cooperation if one wish to succeed in the telecommunication
industry and it has also determined which resources that are deemed to be most important to
get in touch with, for our study object, to facilitate its access to the market. Those resources are
defined as a direct channel to the customer, funds/capital and the access to relevant business
networks. To get in touch with these lacking resources, three alternative approaches has been
proposed; all of them involving a strategic alliance decision.
