Rengöringsmaskin av produktionslina : Rengöring av band i produktion
The project was carried out with SwedSafe AB, engaged in hearing and manufacture of earplugs. Since the company is a world leader in the sale of these products, it is important that they keep a higher level of quality of these products.Production of earplugs is currently a automated manufacturing process that is divided into four conveyor belts and one of the conveyor belts is what will be affected in the project. The belt affected during this process is exposed to various elements such as filling, closing, fermentation and extraction of products. Because the belt gets dirty, degraded products and the work environment is affected. To increase the quality of products and improve the working environment requires an automatic cleaning process, which collects dirt from the belt.The aim of the project is to design a machine that prevents the belt from becoming dirty, preserve molds clean and improve the working environment without disrupting production.
Volymsrapportering vid drivningsarbete
Reporting harvested and forwarded volumes are important for the forest industry as it provides information of the size of the stock and facilitates logistics. Figures from Holmen Skog show low reporting frequency. The purpose of this study is to investigate the reason and find suggestions for improvement. A total of 17 machine operators were interviewed using a questionnaire combined with open questions. The results show that the majority of the machine operators find it simple to use the reporting system, although, some of them reports that it doesn?t always work as supposed to.
Skogsbrukets framtida arbetskraftsförsörjning : skogsmaskinföraryrkets attraktionskraft
The scarcity of qualified forest machine operators as well as the increased competition for competent machine operators among others from the mining industry in Norrland, were the reasons to investigate what attracts and what deters active and potential forest machine operators to the occupation. An interview study was conducted among four groups with four persons in each group. The groups were students in year 1 and 3 respectively at a forestry school at upper secondary school level as well as employees of a forest company and employees of contractors. The majority of all respondents were of the opinion that their interests in machines had been important for the choice of occupation. But for the active machine operators both the interest in the forest and their interest for machines have had importance for choosing this occupation.
Vitamin- och mineraltillskott för barn : Utbud, innehåll samt kunskap och attityder kring dessa produkter hos personal vid apotek och hälsokosthandel
Background:Chronic heart failure (CHF) is a complex clinical condition. The higher survival rate after heart attack and other heart diseases, plus aging population, has led to more CHF patients. Symptoms can have negative impact on exercise capacity, ability to perform activities of daily living and quality of life. Heart failure clinics have been established to help better quality of life. Helping to stabilize and maintain patients´ health can reduce the need of hospital admission.
Kvinna Och Kropp. Två hinder vid en hjärtinfarkt
Purpose: To describe the gender impact on the situation of women at the onset of myocardial infarction and describe why women wait to contact medical caregivers when showing symptoms of myocardial infarction. Method: Literature review with a descriptive design. Articles was retrieved from PudMed and Cinahl. Findings: Women are affected more than men of the so-called atypical symptoms of a heart attack. This means that they can not always relate the symptoms to a heart attack.
Flödesoptimering i begränsande resurs
Most companies have a bottleneck in their production, that is a constraining re-source. When the demand is higher than the capacity in the constraining resource it is impossible to produce the demanded output. This problem leads to delayed deliveries, unhappy customers and ultimately to decreased revenue. Bottlenecks therefore has a significant role in production and must be handled thereof.MW Power in Sävsjö, Sweden designs and manufactures water and steam boilers for the customer's unique needs. MW Power invested in a new plasma cutting ma-chine but the machine has not reached the expected capacity.
Att vara förälder till ett barn med medfött hjärtfel : en litteraturstudie
Introduction : Structural cardiac malformations affects 0.8-1% of children born worldwide, in Sweden 800-1000 children per year. Most children with congenital heart disease and their families will have frequent and lifelong contact with highly specialized care. Awareness of the parents experience is crucial in order to improve the nursing care. These experiences will be illustrated using a theoretical model of family-based nursing. Aim: The aim of this study was to describe experiences of being a parent to a child with a congenital heart disease.
Hjärtfrekvensvariabilitet hos friska hundar
In healthy dogs, heart rate fluctuates during the day. Heart rate variability (HRV) reflects the autonomic nervous system´s regulation of the cardiovascular unit. Heart rate variability shows the balance between the sympathetic and parasympathetic nervous system, also called sympathovagal balance. Heart rate variability can be measured by time domain - and frequency domain analysis. In a time domain analysis you study the beat-to-beat-interval (RR-interval) in an electrocardiogram (ECG), while a frequency domain analysis can be used to determine the size of the variability.

Demonstrationsprojektets roll i framväxten av ny teknik: Fallstudier av två vindkraftprojekt
This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.
Utveckling av nytt koncept till processmaskin
Metso Paper offers a front-running range of solutions and services for the pulp and paper industry. At the baling unit, design solutions are developed for manufacturing and handling of pulp bales. The machines are continuously developed to satisfy customer needs. One big step in the development of the baling line was to remove hydraulics from the machines and replace it with electrical motors and pneumatics. This was not done on the folding machine which is still driven by mainly hydraulics.
Utveckling av ett svensk-engelskt lexikon inom tåg- och transportdomänen
This paper describes the process of building a machine translation lexicon for use in the train and transport domain with the machine translation system MATS. The lexicon will consist of a Swedish part, an English part and links between them and is derived from a Tradostranslation memory which is split into a training(90%) part and a testing(10%) part. The task is carried out mainly by using existing word linking software and recycling previous machine translation lexicons from other domains. In order to do this, a method is developed where focus lies on automation by means of both existing and self developed software, in combination with manual interaction. The domain specific lexicon is then extended with a domain neutral core lexicon and a less domain neutral general lexicon.

Maskinduglighet på planlaserskärare
Lars Höglund AB is one of Scandinavia?s most qualified manufacturers of sheet metal products and provides custom designed products of very detailed precision. One of the main methods of manufacturing is laser cutting. When Lars Höglund AB signed up a new customer, with high demands in tolerances for the products, Lars Höglund AB thought it would be necessary to know the capability of the laser cutting machine. Also the process of how to retrieve this capability was interesting. The capability will be researched for the following elements: Cutting right angles in squares with a corner radius of 1 mmCutting corners which are not right angleCutting of circles with constant radius Measurements were made on 150 pieces of sheet metal details, which had been cut out by the machine. The data from the measurements where later used to study the capability.
