Går det att mäta blodtryck med fotopletysmografi och bioakustisk sensor i kombination?

The aim of the work was to investigate the possibility to combine information from PPG and bio-acoustic technology to extract information that is related to the blood pressure. The measurements have been carried out with several different configurations. First the relation between arterial sounds and the PPG-signal was studied. After those measurements with both PPG and the bio- acoustic technique was concluded on people in different positions and after riding a bike. The goal was to vary the blood pressure.

Demonstratortest av gassensor baserad på tryckt organisk elektronik och jonledande papper

Researchers at Karlstad University have developed a method for making paper ion conducting. The reasearchers want to test this technique in various applications and produce products that make use of the ion-conducting paper. Hopefully this will drive the development forward and result in new applications for the ion-conducting paper.This study was to test the possibility of manufacturing a gas sensor of conducting paper along with electrodes of conductive polymers printed on the paper. By comparing the paper sensor with an electrochemical cell in which the electrodes of conductive polymer replaces electrodes of metal and ion-conductive paper replaces the liquid electrolyte in the electrochemical cell, it was hoped that it would be possible to measure the oxidation and reduction reactions that a gas could introduce at the electrodes.It was shown that it is possible to measure a potential difference in the range of 0.3 V to 0.5 V between the electrodes when exposing an electrode to 100% oxygen. The reaction that takes place is relatively slow and the reaction rate is partly due to the distance between the electrodes.Since the sensor can measure oxidation and reduction reactions it is possible that, in further development of a sensor, the sensor can be made ??into a versatile sensor with more applications than gas measurement as there are many more ways to oxidize or reduce the electrodes than by exposure to oxygen.During the study there have been discussions and meetings held with various companies in the sensor industry to be able to specify what the market demands of a sensor made ??of paper and the requirements that must be placed on the sensor for it to be interesting for the companies..

Gränsöverskridande uttryck i textilkonst - En jämförande studie av två feministiska textilkonstnärer från skilda tidsperioder

Similar to work of the feminist movement in the seventies, you nowadays can see an increased level of textile art expressions with feminist standpoints. In this thesis I compare two textile artists from each time period. These are Maria Adlercreutz with her composition I hennes ögon bevaras folkets ljus from 1972, and Lisa Anne Auerbach?s exhibition Chicken Strikken from 2012. The aim is to put the two artists in a contemporary context and explore their feministic approaches in the textile field.

Att existera i ögonblicket -Töj, en textil sittmöbel

This project started with an exploration of geometric shapes and textile materials. It resulted in a chair made out of textile bands with different elasticity. The surface for sitting is flat when the chair is not used, and changes in the moment you sit down and gets a new shape. A piece of furniture that adapts to each individual. The chair emphasizes the important relationship between human and product as the person using it becomes a part of the chair for a moment..

En naken forntid? - om textilforskningens roll i den övergripande arkeologiska diskussionen

The aim of this essay is to make clear, whether or not, textile research is visualised in a wider archaeological discussion today. The aim is then to discuss what the archaeological and textile technological research situation in Scandinavia looks like today, and how that relate to what has happened in these two research fields during the years. This essay also has a purpose to find out if there is a need of visualising textile research more in future archaeology, how that shall be done, and what that can possibly supply to our general picture of the prehistory.The head questions are discussed in the light of three investigations. The first is a study of literature used in archaeological education at five Swedish universities. The other two consists of a study which is aimed to find out how textile research results are published, and one in which archaeologists and textile researchers have answered questions about how they experience the relation between archaeology and textile research.There has also been done a comparison between interpretations of the archaeological material from the site of Löddeköpinge in west Scania.

Obtaining high quality textile fibre from industrial hemp through organic cultivation

AbstractThe urgency to find alternative fabrics to conventionally produced cotton is increasing as vast amounts of agrochemicals are used and a lot of irrigation is required. In this literature survey the potential of organic cultivation practices to produce highly qualitative hemp fibre, suitable for the textile industry, was investigated. The definition of a fibre in the textile context as well as of the qualities that are essential for a textile fibre was necessary as a base for the discussion in this thesis. The quality parameters looked at were fineness, strength, length, friction, and colour. The impact of external growth factors and plant development on these quality properties are discussed.

Ämnesövergripande arbete i matematik och textilslöjd : Ett praktiskt försök i skolår 6

The aim of this thesis is to try to make the mathematics content of textile handicraft visible. This is done through an attempt at integrated studies in the two subjects with 6th grade students.The main question is: In what way may integrated studies in mathematics and textile handicraft lead to making the mathematics content of textile handicraft visible to the students? This question has been divided into three sub-questions: 1. What knowledge do students have on the order of the millimeter, centimeter, decimeter and meter units of length?, 2.

Det kommer inte alltid att vara så här. En undersökning om mönster och förgänglighet

The purpose of this project was to to find a way for textile patternsto talk about its own, and our, inevitable death. By doing so I hopedto incorporate questions about transience into daily life.I assumed that from a decentralized background position, patternson everyday objects have a unique ability to pose complexquestions that can be interpreted over time. The investigation wasinspired by how russian constructivists looked at everyday objectsas equals, and let them carry the spirit of the revolution.In the process I tried to find out how, and if, a philosophicalmessage can be transmitted through design and how differentcomponents of a pattern can work together to express that message.Resulting in two textile patterns with textile motifs, my workshowed that design definitely can raise metaphysical questions andmay as well have an advantage over art when trying to reach peoplein their own reality..

Textilindustrins avloppsvatten och avloppsslam ur ett miljöperspektiv : Underlag för internationella riktlinjer inom projektet Sweden Textile Water Initiative

The aim of my thesis is to obtain knowledge of textile wastewater and textile sludge from an environmental perspective, which can be used as a basis for the  ?Sweden Textile Water Initiative? guidelines for a sustainable sludge management. In my study I have mainly focused on textile dyes, salts and metals and their routes during wastewater treatment.This paper is partly a literature review, which I began by identifying the pollutants discharged from each textile process. Then I studied wastewater and sludge quality, environmental aspects, possible treatment and recycling methods. I have also tried to find existing type of guidelines in order to make comparisons.

Avståndsmätning med Hög Noggrannhet till Låg Kostnad

Active sensors are used a lot in the society and industry, for example to gain better control over processes or to get proximity sensing features in different products. Within industry there is great interest in developing safe automation products that can be controlled with high accuracy but still at a low cost.The goal of this project is to develop a prototype of a non-contact rangefinder that measures distance using infrared light. The sensor is to be used for various applications in industries with relatively high accuracy and be compact, but at a low cost. By implementing a rangefinder into a product, more accurate detections of an object?s presence can be done.In this project a new distance sensor, EPC600 from ESPROS, was used.

Identified opportunities and challenges inCSR certification : the case of CSC9000T in China?s textile industry

Corporate Social Responsibility (CSR) issues have been received much attention in businessand management practises globally. Jensen & Yeh (2009, 3) state that ?The agenda ofCorporate Social Responsibility (CSR) has emerged as a factor in the process of globalization,and Chinese companies may sometimes feel pushed into this agenda without a clearunderstanding of the rationale behind it?. China?s textile and apparel industry, amanufacturing-based economy with its products bounding up with the consumers worldwide,has been facing enormous pressure to take CSR initiatives, particularly in relation toenvironmental issues and labor standards.
