Utveckling och utförande av frekvensstudie vid Rapid Granulator AB

The object of this examination project is to produce a method of work sampling at Rapid Granulator AB. The aim is to perform the method at the company and evaluate if it is executable. The study is delimited to the basic construction of the 45-series in the assembly hall.Preparations to produce the method of the work sampling resulted in definitions of activities, a form and a product tree. Several days were spent studying the assembling to learn and understand the entirety.The work sampling result showed a large amount of no value adding time that was used in the assembling. Some of the activities could be reduced and we observed some problems during the assembly process.

Utmattningsberäkning av hydraulikkopplingar : Metoder och beräkningar gällande utmattningsteorier

The purpose of this thesis is to investigate the fatigue life of two components in different hydraulic quick couplings. The crack which initiates the fatigue failure usually occurs in the bottom of one of the threads. Thus, the threads in the coupling are carefully investigated. A few different approaches for determining the fatigue life are studied for each component. CAD (Computer Aided Design) models for both components are created and analyzed with FEM (Finite Element Method).

Prövning av måttet Läpp-till-Lyft (L-t-L) på vuxna utan sväljsvårigheter

Context: Lip-to-Lift (L-t-L) is a bedside-method for measuring oral transit time at swallow. It was designed for a swallowing examination of persons on nursing homes where weight loss was noted in people with average L-t-L-time >5 seconds (Sandin, 2005). The measurement was validated and evaluated by Eriksson, Bremer Zerpe (2008).Objectives: The study objective was to examine L-t-L on a group of young adults without swallowing disorders and as to examine the inter- and intra-judgereliability of the measure.Questions:What is the L-t-L-time for young adults without swallowing disorders?Are there any gender differences regarding L-t-L-time?How high is the inter/intra-judge reliability of L-t-L?Method: Examination of L-t-L-time was carried out on 20 young adults, aged 19-27 years, without swallowing disorders after Sandin?s (2005) instructions. Measurements of 20 swallows per person were made.Results: The average L-t-L-time of young adults without deglutition-difficulties was 1.13 seconds (sd =.14).

Ena dagen student nästa dag nyutexaminerad sjuksköterska

Background: Every year about 4600 nurses are examined in Sweden. The work as a nurse is responsible and she is often working under time pressure. Aim: To describe nurse?s understandings about her professional role during her first year after the examination. Method: Systematic literature review, where 10 scientific articles were examined.

Manuell arytmitolkning och defibrillering prehospitalt för att minska avbrott i bröstkompressioner

Abstract Background Todays guidelines for advanced CPR emphasize chest compressions with good quality and early defibrillation. Prehospital CPR performed by ambulance crew, an automated external defibrillator (AED) is used. The AED analyzes the heart rhythm and the performer is following the advice to chock the heart or not, given by the AED. During on-going CPR there are sequences when no chest compression is performed known as hands-off time. Hands-off time includes the time for the AED to analyze the heart rhythm and the time when advice is given to the crew.

Matematisk generering och realtidsrendering av vegetation i Gizmo3D

To render outdoor scenes with lots of vegetation in real time is a big challenge. This problem has important applications in the areas of visualization and simulation. Some progress has been made the last years, but a previously unsolved difficulty has been to combine high rendering quality with abundant variation in scenes. I present a method to mathematically generate and render vegetation in real time, with implementation in the scene graph Gizmo3D. The most important quality of the method is its ability to render scenes with many unique specimens with very low aliasing.

Analys av faktorer som påverkar interna leveransledtider : Dimensionering av lager

It is becoming increasingly important for companies to meet customer demands due to intense competition in today's global market, that forcing companies to improve their offerings and become better at managing their supply chain (Shen et al., 2006).  Long lead times can be reduced by using different methods and strategies shows various researches. Lead times occur in the planning, production, inventories and handling of products (Treville et al., 2003).The aim of the study is to develop a method to analyze the factors that affect the length of internal delivery lead time in manufacturing companies. The method also included suggestions for reducing delivery lead-time to internal customers.The main factors that influenced the length of the on delivery lead times has summarized to make a selection among the factors that can have the most significant impact. The selected elements will be used as a method to analyze how these areas affect a company?s length on internal delivery lead times.The study shows that the causes of the long delivery lead times was the location of the customer order point, uncertain forecasts, long material and production planning time, and long waits in the production and storage.The delivery lead time, according to this report?s suggested improvements reduced by centralizing CODP and makes more reliable forecasts.

Energiåtervinning : av kompressorkylvattnet

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

Förbättring av den svenska kiselalgsmetoden-hantering av sedimentering

Benthic diatoms are used in Sweden for monitoring water quality in run-ning water; the method is also frequently used in other countries in Europe. One of the problems of the diatom method is the need for sedimentation of the fresh sample, to be able to decant the over standing water and add alco-hol as a preservations solution. To my knowledge, no results have been published about how long the settling time must be to ensure that the ben-thic diatoms really have settled down to avoid a loss of the diatoms when decanting the over standing water. The aim of my investigation was to improve the Swedish method where the benthic diatoms are used for water quality monitoring. I wanted to find out the appropriate time necessary to wait until all diatoms have settled down before decanting the over standing water. First, fresh benthic diatom samples were taken in the river Fyrisån and the lake Mälaren on different days. After arriving in the laboratory, I waited three different times (30 min, 60 and 180 min) for the diatoms to settle.

Realistisk restidsberäkning för comodal reseplanering

With increasing traffic congestion problems in bigger cities, it is becoming more and more important to provide the traveller with correct information about all transport alternatives. When doing that, the traveller gets the opportunity to make the best decision based on the current traffic situation. Instead of traditional travel planners, where public and private transport modes are presented separately, the co-modal travel planner offers a combination. In order to make the comparison correct and fair, the travel times have to be estimated realistically and on equal basis. This master thesis focuses on how to estimate travel times in the city of Stockholm for journeys by cars, public transport, bicycles and also for walking.An investigation of the available data on maps and travel times shows where the currently used methods are lacking.
