Identifiering av stelkroppsmodell för industrirobot

In this masters thesis we consider a method for experimental identification of the inertial parameters of an industrial robot, using measured torques and joint angles. A dynamic model of the first three joints of the robot has been identified.To achieve good identification results, it is important to carefully choose the trajectory for the experimental identification. A method to generate trajectories using two suggested design criteria has been used and evaluated using an ABB industrial robot, and one of them yields good identification results..

Rekursiv greyboxidentifiering av drivsystem i industrirobot.

In modern industrial robots the components in the transmission contain nonlinearities. These nonlinearities need to be to estimated either for better control or to use the parameters for diagnosis of the system. There is a lot of work done within system identification and mainly within the field of iterative parameter estimation.This thesis considers recursive grey-box identification for a nonlinear model of the transmission in an industrial robot. The nonlinearities that are identified are friction, spring stiffnes, hysteresis and backlash. These nonlinearities are a part of the models that are presented in this thesis.

Identifiering av synkronmaskinsmodell genom SSFR-test

At the Division of Electricity at Uppsala University there is an experimental rig forhydroelectric generators. The experimental rig?s vital part is a 12-pole synchronousmachine, whose electrical characterizing parameters (resistances, inductances andtime constants) are unknown. The aim of this thesis is to characterize the machine inits current state by perform a Standstill Frequency Response (SSFR) test. From theanalysis of the measurement data, which is a part of the test, a set of basic parametershave been received.

Plain Capital - Where the magic happens : En fallstudie om organisationsidentifikation 

Purpose: The aim of this thesis is to create a greater understanding of organizational identification and the factors influencing this process. The understanding will be obtained by identifying what individuals identify them selves with and why this identification occurs.Method: The thesis is a case study with an abductive research approach with a focus on organizational identification. Data has been collected with a qualitative focus in interviews and images.Conclusion: The employees at Plain Capital primarily identify themselves with their profession, the company and their co-workers. The reasons why they identify are mostly because of the feeling of pride and participation. We have discovered a link between a strong group identity and a high organizational identification.

Brand Identification hos internationella distributörer : En studie i skapandet av Brand Identification - och dess effekter på varumärket

Syfte: Syftet med studien är att beskriva hur svenska modeföretag arbetar för att skapa Brand Identification  hos sina externa distributörer, samt vilka faktorer som påverkar möjligheterna att skapa Brand Identification. Vidare är syftet att belysa vilka tillvägagångssätt svenska modeföretag använder för att tackla faktorernas inverkan på skapandet av distributörernas Brand Identification.Resultat: Studien visar att arbetet med Brand Identification är viktigt redan i ett inledande skede av ett samarbete. Förmågan att skapa en känsla av tillhörighet är viktig för att Brand Identification med producentens varumärke ska vara möjlig, särskilt då distributören arbetar som representant för flera varumärken. Tillvägagångssätt för detta är kommunikation som är riktad mot distributörens säljkår samt socialiseringsprocesser vid personliga besök hos distributörerna..

Identification of inhalation pauses is an important step in the developmentof automatic methods for spontaneous speech parsing.Identification of inhalation pauses is considered to be a keyword-spotting speechrecognition problem. Hybrid HMM(Hidden Markov Models)/ANN(Artificial NeuralNetworks) approach is applied to this problem. Method gets 90,8% in Recall, 66,4% inPrecision and 76,7% in F-score.

Socialization and Identification of New Recruits in Knowledge Intensive Firms: A Case Study

Using the models from van Maanen and Schein (1977) and Dutton et al. (1994), we have been able to investigate the socialization process and organizational identification both from the organizational as well as the individual?s perspective. The link between these two perspectives establishes a better insight into the company?s actual socialization intentions and the individual?s identification with the firm.

Modellering, identifiering och reglering av skannern i ett laserbatymetrisystem

The purpose with this masters thesis was to model the scanner in a system for laser bathymetry. The model was then used to develop a controller for the scanner so a good search pattern was achieved. Two different types of models have been tested, a physical model and a Black Box model of Box Jenkins type. The physical model has been derived from Lagranges equations. Identification experiments have been used to compute the Black Box model and to find the unknown parameters in the physical model.

Kan professionell skepticism användas för att förutse revisorers beteende?

Auditors have a big role in society. The question of auditor independence has been debated frequently after the financial crisis. Long auditor tenure with clients has both advantages and disadvantages so the question is hard to solve.One of the traits that are encouraged with auditors is professional skepticism. An important part of professional skepticism is the personal skepticism of the auditor. The purpose of this dissertation is to investigate if a high professional skepticism can increase auditor independence by increasing profession identification and decreasing client identification.

Identifierings- och igenkänningssystem för markförband, lösningen för att undvika vådabekämpning?

Syftet med uppsatsen är att belysa möjligheter och begränsningar med olika tekniska system för att identifiera kontakter på stridsfältet, främst med avseende på att minska risken för vådabekämpningar.

Genom statistisk analys utvärdera geometriska parametrars påverkan på ett XPI- cylinderhuvuds snurrtal

This Master Thesis is a product development project that has been carried out in cooperation with Scania CV AB. The purpose has been to find the relationship between geometric parameters and the swirl number for an XPI- cylinder head in order to improve the design specification.The increased focus on environmental issues from society leads to tighter emission legislations for the truck manufactures. In order to drive the development forward considerable resources are spent on research and development on diesel engines and its combustion process. The inlet air has a significant impact on the formation of emissions and the flow that is desired is called swirl. Swirl is achieved by making the air rotate around the vertical axis of the cylinder.Earlier cylinder heads that has been developed at Scania CV AB have shown clear relationships between geometric parameters of the cylinder head and the swirl number.

Hemma i världen(globen?) En studie av social förändring och identitet

In this thesis my purpose is to study the mechanisms and discourses that are the foundations for identification processes, in a contemporary society characterised by increased mobility. By means of a fictitious life history, I relate to this problem constantly through the work. At the beginning of the essay I discuss the traditional, western, philosophical view of the self and its surroundings, which eventually leads me to focus on the theories of the sociology of knowledge. From this perspective I choose to examine globalisation processes and mobility, to create an understanding of how these two, changes the circumstances for the individual identification. In my concluding argument I stress that all research or all studies concerning identification processes must take into account that these identifications always take place with regard to time/place which also means, that it takes place both in real space and in imaginary space.

Utvärdering av vibrationer inom vattenkrafts normer

The International Organization for Standardization (ISO) proposes vibration standards for the evaluation for machine damage due to vibration in rotational machines, where some vibration parameters are given to measure the vibrationgrade. This work evaluates the relevance of the vibration standards in hydro plants that are proposed by the ISO, and also investigates if there are methods used in other countries could have greater importance. Through statistical analysis of collected data we got a better understanding of relation among different vibration parameters, and also the importance of correct choice of the parameters for the evaluation of vibration. We have found that the vibration standards available today in hydro plants are not reliable for the judgment of vibration?s grade.

Individual identification in pigs using microchips

Individual identification of pigs could be used in commercial herds for production monitoring, disease monitoring and breeding evaluation. This study investigates the possibility of using microchips designed for dogs and cats to identify individual pigs from birth, through rearing to carcass at the slaughter plant. Two different sizes of microchips, and two different ages of the pigs at injection were tested. Castrates and gilts from ten litters were evenly distributed between chip sizes and injection ages. All pigs were identity marked with both electronic ear tags and injected with microchips.

Tecken på smärta under anestesi - hur anestesisjuksköterskan bedömer patienten

ABSTRACT Introduction: One of the great difficulties that the nurse anesthetist encounter in their profession is to assess and estimate sleep depth versus signs of pain in the anesthetized patient. Based on a pre-operative appointment and the perioperative monitoring, an assessment of the patient is made. The experience that the nurse anesthetist has can make it easier to understand what subtile signs of the patient depends on. Purpose: With this in mind, the purpose of the pilot study was to try to find out if there are specific signs of pain during anesthesia and if the professional experience played a role. As a subsidiary aim the authors examined whether there were factors in the patient that the nurse anesthetist takes into account in the identification of pain during anesthesia.
