Teststrategier och användning av testautomation : En studie utförd på företaget Extenda AB

In today?s IT world where software is constructed in a rapid pace, testing has become a crucial area to master when testing has to be done at a greater speed. To still be able to handle the demands of high quality software, companies have to spend more resources on testing and introduce test Automation. By automating test cases the testers can gain time which they can spend on doing more complex testing and thereby increase the quality of the software.In this thesis we have helped Extenda AB, who delivers systems to retail companies, to introduce test Automation in one of their customer specific projects. This has been done using their own in-house ?capture/replay? tool ECP (Extenda Cashier Player).We have also derived a process that explains how Extenda can introduce test Automation on other customer projects.

Aktörer och artefakter : Ett samtida perspektiv på bibliotek och automatisering

This bachelor thesis examines the activities and values associated with Automation and technical development at four Swedish research libraries. It does so by applying textual analysis to annual reports and job advertisements from the respective libraries. The study also questions whether some assumptions of Automation have changed or remain over time, and includes a short historical discussion in relation to the contemporary analysis. As an added perspective it introduces the methods and philosophies of French sociologist Bruno Latour. The author reflects on the merits of Latour in research of library Automation.

INDUSTRIELL AUTOMATION : Behov och möjligheter med ökad användning av internationella standarder i tillverkningsindustrin

Standarder används i alla organisationer som en frivillig överenskommelse om att lösa ett återkommande problem eller en rekommendation på ett arbetssätt.Standarder inom industriell Automation SIS/TK 279 har använts inom tillverkningsindustrin under lägre tid men pga. många faktorer begränsades dess användning.Syftet med detta arbete är att undersöka vilka faktorer som orsakades de nuvarande begränsningarna och hur skulle kunna reducera både tid och kostnader genom att nyttja dessa standarder, och på så sätt demonstrera behovet av standarder för industriell Automation. Genom att använda sig av kvalitativa metoder skall kartläggningen ge en överblick av de befintliga internationella standarderna inom industriell Automation . Behovsinventering skall ske genom att intervjua aktiva personer inom Automation och litteratur studie. Sedan skall föreslås hur olika standarder för industriell Automation kan fylla behovsgap och öppna upp för nya möjligheter inom den svenska tillverkningsindustrin.Analysen resulterades i de nuvarande begränsningsproblem som orsakades av följande; Bristande kunskaper om standarder som förekommer i alla delar av näringslivet. Bristandande resurser i form av brist på kunniga personer och ekonomiska hinder.Svårigheter för tolkning och tillämpning av standarder.Ovanstående och många andra faktorer minskar intresset för deltagning och framtagning av nya standarder inom industriell Automation.

Automation i Distributionsnät

As a part of Göteborg Energi?s work towards a smarter electric grid, the company has chosen to investigate the possibilities of Automation in their middle voltage grid. In Europe, there are example cases where these technologies already are installed which many articles on the CIRED conference 2011 proved. Netcontrol Oy in Finland has, together with Tekla, created an automated SCADA system that Vattenfall in Finland today uses. The grid mainly consists of 10 kV open loop fed city grid and this Automation is mainly designed for this type of grid.

Det Intelligenta Huset : - En studie i hemautomation

Today all buildings contain some form of home Automation. It might be heating controlled by athermostat or motion detectors controlling outdoor lighting.This paper,The Intelligent House, deals with the planning of a house in Kiruna, in the north ofSweden and further immerses itself in home Automation or intelligent control in single-familyhomes. The house has been entirely planned, from layout to structural design and plumbing.The purpose of the paper has been to investigate the possibilities in home Automation in singlefamilyhomes and to choose a suitable home Automation system for the house being planned.The system has been designed and the costs and energy savings have been calculated.The system chosen for the house is called KNX and is the largest system for home Automation inSweden. It is used to control heating, ventilation, lighting and alarm systems in the house. Is hasbeen found that KNX is very expensive and that the amount of energy, possible to save in thehouse, using the system, is relatively small.

Framtagning av en utvecklingsprocess för automation - baserat på konceptet Lean Automation

Due to the globalization today the competition in the market has in- creased and it requires flexibility and produce according to customer demand. In order to reduce the cost of wages industrial companies are now considering moving the manufacturing to low-cost countries. To keep up with the competition in the market without moving the manu- facturing abroad, Lean Automation was developed. The concept of Lean Automation is to reduce the perceived complexity with automa- tion and make Automation available for new users and in new applica- tions.Haldex Brake Products are situated in Sweden and want to maintain the manufacturing of the automatic brake adjusters in the country. It is a product well-known and highly exposed to the competition in the mar- ket.

Utveckling av ett öppet Home Automation-protokoll för användning över IP-nätverk

Detta arbete tar upp utvecklingen av ett nytt protokoll för användning inom Home Automation över IP-nätverk, med stor vikt på flexibilitet och enkelhet. Vi valde att utveckla ett nytt protokoll för Home Automation då en granskning av dagens protokoll visar att dessa inte är tillräckligt öppna eller flexibla för att passa alla enheter som används eller alla scenarion som kan uppstå.I våra litteraturstudier samlades information in som skapade grunderna för vårt protokoll och gav oss en större inblick i teknikerna bakom dagens tekniker inom home Automation. Detta gav oss även möjlighet att senare jämföra vårt färdiga protokoll med redan existerande protokoll för att se om vi lyckats skapa något som kan användas. Metoden vi valde för att utveckla protokollet är en generell designmetod där vi efter granskningen av tidigare protokoll tar fram ett antal punkter som det nya protokollet skall uppnå. Det visade sig dock vara problematiskt att få fram svar om vissa protokoll så vi frångick metoden genom att istället utveckla protokollet utefter ett antal olika scenarion som det bör kunna hantera.Resultatet av arbetet är ett protokoll som uppfyllde nästan alla mål vi satt upp för det.

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.
