Sensorfusion för undervattensrobot i kärnteknisk miljö med Kalman filtrering

WesDyne TRC AB is a fully owned subsidiary of the global WestinghouseElectric Corporation. WesDyne is a world leader in non-invasive methods for theinspection of nuclear power plants. One of the inspection platforms used to scanfor defects in and around the welds in the reactor vessel is called the T-crawler.The T-crawler operates under water in a radioactive environment by stepping onthe vessel (reactor tank) inner wall using suction cups. The environment is harshand many traditional positioning sensors are not suitable for implementation. Thisthesis investigates the possibility to use a gyroscope and a pressure sensor tocreate an alternative and independent positioning system.

Optimering av ultraljudssändare- och mottagare avseende räckvidd, strålningsvinkel och energiförbrukning

Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..

Estimering av GPS pålitlighet och GPS/INS fusion

The Global Positioning System (GPS) provides location and time information as long as there are unobstructed lines of sight to four or more GPS satellites. However, when this is not the case the signal may be inaccurate or sometimes even completely blocked. In these situations the Inertial Navigation System (INS) is an appropriate choice for positioning.  An INS has already been proposed in a previous thesis by Erik Andersson and the objective of this thesis is to fuse the GPS with the INS in a proper way. A part of this project is to decide the reliability of the GPS.Three methods for GPS reliability detection have been proposed. One method based on the statistical properties of each of the separate systems, and two methods based on the statistical properties of the residuals between the GPS and INS.

Positionering för överlevnad? : - en kvalitativ studie om nystartade företags arbete med sin positionering

Purpose:Only 60 percent of the newly started companies survive their three first years. The purpose of this report is to obtain a deeper understanding regarding how newly started companies work with their positioning and if there are some kind of a relationship between positioning and the survival rate of newly started companies.Research questions:Do newly started companies know what position is? Do they incorporate positioning in their day to day marketing?Approach:We have used a hypothetical-deductive way of reasoning and a qualitative study to gather the information needed. We have through interviews asked our questions to six newly started companies in three different cities.Findings:In our essay, we reached the conclusion that newly started companies do not spend sufficient time or energy on positioning their products. The companies interviewed only market their product as a good product.

Utveckling av nytt koncept för positioneringsslid

A manufacturing machine at the engineering company Sandvik Coromant has a positioning table which task is to move an item linearly. The positioning table has a linear motor capable of high velocity and acceleration. This makes it possible to achieve short cycle times and a more profitable production.The purpose of this thesis is to bring forward a new concept which is more adapted to the requirements of the positioning table. The reason is that the current positioning table provides an unnecessarily positioning accuracy of 0.01 mm, while the requirement for the positioning accuracy is just 0.1 mm. The goal is to reduce manufacturing and component costs.To develop a suitable solution an approach for the concept development process has been performed.

Positionering av industriella tjänster

This thesis aims to investigate the positioning concept of industrial services. We chose to identify the reasons why positioning is used as well as to describe the positioning process. The research strategy chosen for this thesis was a case study of a consultancy firm Benima AB. This firm was chosen due to the fact that a new positioning concept during the latest year hade been implemented and therefore seemed like a good choice for our study. Of the six available theoretical reasons for positioning, we found that Benima AB had two of them: namely change in target market or their needs and demands and renewed company identity/personality.

Corporate Brand Positioning

PURPOSE: To investigate to what extent product brand positioning models can be used to analyzecorporate brand positioning;METHODOLOGY: The phenomenon is observed from a positivist epistemological position within a primarilyinductive research design. The research strategy is defined as qualitative, while the method of ethnographiccontent analysis is implemented to analyze primary data;THEORETICAL PERSPECTIVE: Product and brand positioning literature; Product brand positioning rhombus;EMPIRICAL DATA: Ethnographic content analysis of brand commercials;CONCLUSION: As shown by the extensive literature review product brands (PB) and corporate brands (CB) coexistin corporate environments. One of key insights of this study shows that product brand positioning(PBP) and corporate brand positioning (CBP) processes can also co-exist in the same corporate environment.Moreover, PBs can be built based on the CB, making the investment in CB a long term return on investment.The study also observes that PBP messages include the ?against whom? attribute, highlighting differentiationin the competitive environment; when on the corporate level, this evolves, and in some cases becomes quitethe contrary, when the concept of ?from whom? or ?by whom? is stressed more than the differentiation amongother CBs in the competitive environment. This stresses the importance of including brand identity elementsin CBP..

Indoor Positioning Using WLAN

This report evaluates various methods that can be used to position a smartphone running the Android platform, without the use of any special hardware or infrastructure and in conditions where GPS is unavailable or unreliable; such as indoors. Furthermore, it covers the implementation of such a system with the use of a deterministic fingerprinting method that is reasonably device independent, a method which involves measuring a series of reference points, called fingerprints, in an area and using those to locate the user.The project was carried on behalf of Sigma, a Swedish software consulting company..

Affärsplanering i små företag: en studie om segmentering och
positionering

Lots of choices are to be made by a company who enters a new market with a new businessidea. Common questions that show up when a company is making it´s businessplan are how to target the market and how to use marketing as a tool to reach a specific customer or segment. It is difficult to know wether to target the market in different ways and what processes that can be used in the choice how to select the most potential and profitable customer. Another important question is how a company can positioning themself in a way so the customer will get a positive understanding of the company and what different positive abilities to mention in a possible businessproposal. This study is made on a small company in Sweden called AYEN Technology.

MONOLITH : TCP/IP kommunikation och seriell dataöverföring

Bofors UwS (Underwater Systems) har påbörjat utvecklingen av ett nytt centraliserat system för att koordinera alla torpedhanterare ombord på ett fartyg till en central enhet. Detta system måste kunna ta emot och i vissa fall sända data till de övriga delsystemen ombord på fartyget. För att lyckas med detta behöver de en kommunikationsapplikation till denna centrala enhet. MONOLITH är en prototyp av en sådan applikation. Dess huvudändamål är att demonstrera hur detta kan utföras och att testa enheter som kan kontrollera ett antal torpeder.
