In the pursuit of a system capable of measuring pain signals in humans we propose a method to differentiate those signals related to pain from those which are not. We performed a time-frequency analysis using the Gabor transform to have complete information about the spectrum and its behaviour through the time to study the main differences over the evoked potentials provoked by both nociceptive an
Abstract On May 18th in Abu Dhabi, UAE, IRENA released a report declaring that Djibouti can meet 100% of energy demand through renewable energy sources by 2020. Today, 55% of the population lives without access to electricity, 60% is unemployed, and the country depends greatly on imports of energy sources, inter alia fossil fuels and electrical power, which contribute to the continued rising leve
When viewing moving objects in videos the movement of the eyes is called smooth pursuit. For evaluating the relationship of eye tracking data to the moving objects, the objects in the videos need to be detected and tracked. In the first part of this thesis, a method for detecting and tracking of moving objects in videos is developed. The method mainly consists of a modified version of the Gaussian
A short introduction to optimal control problems is presented. For these problems the calculation of sensitivity matrices with the method of adjoint equation is shown. The adjoint equations are derived with the corresponding initial values. At the end two examples are calculated.
This study has focused on challenges encountered when setting up a weather-network for agricultural purposes (e.g. linking temperature to the suitability of crops and pest incidence) with only low-cost sensors and materials. The study included a set of experiments in a meteorological station and a one-month period of observations in a large coffee plantation with a complex terrain in Costa Rica. T
Like many other lakes, Lake Ringsjön in Sweden has a long history of eutrophication problems. Eutrophication of lakes is mainly due to surplus of phosphorus. Most phosphorus reaches Lake Ringsjön from adjacent watercourses. In order to initiate action plans to reduce phosphorus concentrations in the lake, it is of great importance to know which watercourses have high phosphorus concentrations. Pho
Sammanfattning En arbetsgivare är enligt lag förbjuden att diskriminera en arbetstagare, praktikant eller arbetssökande med en funktionsnedsättning. Det föreligger en skyldighet för arbetsgivaren att vidta de stöd- och anpassningsåtgärder som anses nödvändiga och rimliga för att de individer med funktionsnedsättning ska hamna i en jämförbar situation med individer utan funktionsnedsättning. Med b
Religionsfrihet i arbetslivet är ett aktuellt ämne som ständigt utvecklas och möter nya utmaningar. En dagsaktuell del av religionsfriheten är möjligheten till samvetsfrihet för barnmorskor, vilket innebär att en barnmorska kan vägra utföra aborter med hänvisning till sin religion. Syftet med denna uppsats är att undersöka möjligheten till samvetsfrihet i Sverige. För att undersöka detta har jag aFreedom of religion at the workplace is a current topic that is constantly evolving and facing new challenges. An up-to-date part of the freedom of religion is the possibility of freedom of conscience for midwives, meaning that a midwife can refuse to perform abortions, according to their religion. The purpose of this essay is to examine the possibilities of freedom of conscience in Sweden. To exa
The purpose of this essay is to examine how the Shoah affects Israeli society today and deals with the construction of identity and collective memory of the Post-Shoah generations in Israel. The study analyzes three Israeli documentary films through the theory of Marianne Hirsch’s “postmemory”. These films are The Flat (2011), Six Million and One (2011), and Defamation (2009). The essay cast its l
Increasingly popular, distance education has been researched from many angles, but studies done from a cultural analytic perspective are rare. Most studies up to this point have focused on the pedagogical perspective. This thesis aims to investigate challenges faced by different stakeholders in distance education, including online course promoters, teachers, and students, from a cultural analytic
Much of the equipment used in Snoezelen environments today is not interactive, and the equipment that is interactive can be hard for the user to access. By having interactive equipment in Snoezelen environments the user gets to experience and hopefully better understand the concept of cause and effect. The purpose of this master thesis has been to develop an interactive interface that can appeal
Sony Mobile has a quite large internal user group with the purpose of investigating the usability of their mobile devices. The Telephony Domain was using among other techniques usability testing to evaluate the usability of their products. The performed conventional usability testing has its limitations e.g. the controlled test environment cannot fully represent real life setting and it’s very exp
Since the boom in global food prices in 2008, governments and companies around the world seek to boost agricultural output and sustain internal food security through the purchase and lease of farmland in Sub-Saharan Africa. There is no consensus in the literature whether land acquisitions by foreign investors are beneficial to the livelihoods of the local people in Africa. This thesis aims to cont
Collimated Transmission Spectroscopy (CTS) is a technique that is commonly used to study the optical absorption of different media. In this work CTS was used to measure the absorbance of pure raspberry juice in order to investigate how well the fruit content may be determined in a commercially available raspberry fruit drink. Another method, RGB colorimetry, which is a much more available techniqu
The following thesis sets out to identify and map out the current problems that a circular economy, where waste management is the main focus, faces within the construction sector among entrepreneurs mainly in the southern parts of Sweden. As well as proposing solutions to said problems which are deemed to be applicable and have potential according to the authors. Construction waste amounts for one
Enligt Socialstyrelsen (2017) är förekomsten av ångest bland barn cirka 10 %. Studier visar att sen eller utebliven behandling kan leda till långsiktiga biverkningar i olika aspekter. Med tanke på detta är det viktigt att erbjuda vård för att förhindra negativa följder som psykiatriska sjukdomar. Studier har visat att KBT är en effektiv behandling för ångestsjukdomar som uppträder under barndomen,
The world continues to be shaped by crises in both new and familiar forms. International and non-international armed conflicts and disasters are barriers to individual wellbeing, development, stability, and in the case of the former, represent a basic challenge to peace. The aftermath of such crises, in which communities can be rebuilt and the fabric of society can be mended, can be a time for rec
Poly-3-D-hydroxybutyrate (PHB) is a biopolymer naturally produced by a range of bacterial species. PHB production both from glucose and xylose has also been enabled by engineering the robust baker’s yeast Saccharomyces cerevisiae, however yields remain low. In the present study, additional modifications were carried out in S. cerevisiae strains already expressing functional enzymatic pathways for
