In this report, the implementation of a technology called sensor-based sorting technology is analyzed from different perspectives. The technology can be used to identify individual particles in order to sort wanted material from unwanted material. Today, the technology is widely used in different industries such as the food industry, the recycling industry, and to some extent the mining and minera

The purpose of this paper is to investigate the possibilities of optimizing the production of paper pulp in a Conical Disc (CD) refiner for different production rates, taking into account the variables that are thought to be the most important for the production. These include three separate dilution waters, conical disc gap and flat gap. Another task is to compare the values of these variables af

Millions of deaf people around the world live without the possibility of going to school or learning a language and experience a prolonged disconnection from their social environments. The purpose of this study was to explore deaf people’s experiences in Mongolia of a transition from social and psychological isolation towards a process of inclusion. The research was carried out by using mainly n

This thesis investigates the ontological meta-narratives of glitch art and focuses on it as the transition from images with noise, into a site of meaning. In the first chapter I will discuss glitch art as a failure in communication that stimulates our perception. By relating glitch art to noise art, I will describe the prevalence of a common artistic approach towards errors, while through Fiske’s

The purpose of this thesis is to explore the possibility of asymmetry in the dynamic conditional correlation of stock returns and gold returns. We hypothesize that this asymmetry might be different for large and small firms, as a result of size specific characteristics that may influence firm profitability and risk following negative market shocks. We investigate this on three different sized U.S.

The sun is an important reason to why there is life on earth. To be able to predict future solar activity it is important to uncover past solar activity and its cyclicity. This thesis investigates the solar activity throughout the past 2000-years to the beginning of 21th century. Diagrams which contain relevant data from radionuclide and sunspot records have been constructed to get a better overvi

Urmia Lake is the largest habitat of Artemia Urmiana in the world located in an endorheic basin in northwest Iran. This shallow terminal lake has been designated as a Biosphere Reserve by UNESCO and a National Park under the 1971 Ramsar Convention. Currently, the entire lake’s watershed is threatened due to its abrupt desiccation of more than 50% of its surface area and the concomitant increase of

All languages distinguish between genders to a varying degree. Gender stereotypes in language are often gender-specific, where agentic words are considered as male and communal words are considered as female. Studies have found that countries with gendered languages express more sexism, compared to countries with natural gender or gender-neutral languages. The following study will investigate the

The advantages with infrared heating and the fact that the technology has become significantly more inexpensive opens up a bigger interest to develop products using infrared heaters further. What will the future kitchen look like? How can infrared technology develop and create more conventional and intellectual products processing our food? By pushing the limits of the technology today the main

Alla ekosystem, skogar, sjöar, hav etc., är föränderliga och står under konstant påverkan, såväl inre som yttre, vilken försöker driva det för stunden rådande tillståndet åt olika håll. Sjöar har två dominerande tillstånd som de kan befinna sig i, antingen är de näringsfattiga och klara eller så är de näringsrika och grumliga. I den har studien har jag undersökt Börringesjön, i södra Skåne. SyftetAbstract All ecosystems, forests, lakes, seas etc., are changeable and are under constant influence, inner as well as outer, that try to push the for the moment present state in different directions. Lakes have two dominating states in which they can exist, they are either clear and low in nutrients or turbid and high in nutrients. In this study I have been examining lake Börringesjön in the sout

Background: Supply chains become more and more complex. Mapping can be a good way to understand a company’s supply chain and its processes. IKEA’s Direct Delivery Customer (DDC) process has a rather unique characteristic at IKEA. By using a make-to-order strategy are sofas, sofa covers and custom made worktops delivered to customers’ home from the supplier. The material flow goes through IKEA’s Cu

The objective for this master thesis has been to develop a mathematical model of the actuator parts of the fifth generation Haldex AWD system. The parts to be modeled are the DC-Machine and the pump. Also a model of the elasticity of the clutch has to be derived as well as a model for the hydraulic fluid. These models were then to be implemented in Matlab Simulink. The model was derived by means o

Abstract Peroxisome proliferator-activated receptor gamma (PPARγ) is expressed in multiple tumor cells as well as macrophages, and has been identified as a putative target for the development of novel therapies against colon cancer. Stimulation of the nuclear receptor PPARγ transcriptional activity can suppress colon carcinogenesis. To understand the molecular mechanisms underlying the anti-tumor
