Support Vector Machines for Classification applied to Facial Expression Analysis and Remote Sensing

The subject of this thesis is the application of Support Vector Machines on two totally different applications, facial expressions recognition and remote sensing.The basic idea of kernel algorithms is to transpose input data in a higher dimensional space, the feature space, in which linear operations on the data can be processed more easily. These operations in the feature space can be expressed in terms of input data thanks to the kernel functions. Support Vector Machines is a classifier using this kernel method by computing, in the feature space and on basis of examples of the different classes, hyperplanes that separate the classes. The hyperplanes in the feature space correspond to non linear surfaces in the input space.Concerning facial expressions, the aim is to train and test a classifier able to recognise, on basis of some pictures of faces, which emotion (among these six ones: anger, disgust, fear, joy, sad, and surprise) that is expressed by the person in the picture. In this application, each picture has to be seen has a point in an N-dimensional space where N is the number of pixels in the image.The second application is the detection of camouflage nets hidden in vegetation using a hyperspectral image taken by an aircraft.

EFFEKTER AV STABILITETSTRÄNING I FOTLEDEN EFTER SKADA : EN LITTERATURSTUDIE

Breast cancer is the most common tumor disease among women in Sweden. About 7000persons, having a median age of 65, are diagnosed each year with this disease. Withmammography screening, breast cancer can be detected in an early stage which improves theoverall survival (OS). 20-30 % of the breast cancer tumors are overexpressing humanepidermal growth factor receptor 2 (HER2), which is a protein that stimulates cell proliferation.Trastuzumab (Herceptin®) is a humanised monoclonal antibody that targets the HER2-proteinand prevent the signals for cell proliferation.Trastuzumab has earlier been used for treatment of metastatic breast cancer. In the year of 2007trastuzumab was approved for adjuvant treatment of patients who has been medicated withsurgery and/or radiation.The aim of this study was to investigate the effects of adjuvant treatment with trastuzumab inHER2-positive breast cancer patients.

Oljetemperaturens inverkan på motoroljans degradering i lastbil

The market for heavy duty engines is constantly requiring engines that should be more andmore powerful, while still maintaining low fuel consumption. As a result of increasing enginepower, the engine and coolant temperature increases as well due to insufficient coolingperformance (because of design issues, cost etc.).Also, emission legislations, both current and future, require more and more measures to betaken by engine manufacturers. One way of meeting the legislations is the use of cooled EGR(Exhaust Gas Recirculation), which also lead to increased coolant temperatures.Both these factors also naturally lead to increased engine oil temperatures, the consequencesof which are not thoroughly investigated.This thesis project aims to investigate effects of high temperatures on engine oil degradation,with focus on the greatest degradation process: oxidation. To do this several engine runs havebeen performed on a 310 hp engine with EGR to see what happens to the engine oil in a realengine when exposed to high temperatures. During the tests oil samples have been taken andanalysed for important parameters.As a complement to these engine tests some laboratory oxidation testing have also beenperformed, to be able to compare engine test data with laboratory tests.One goal of the project was to try to formulate an empirical oxidation model, which would beable to predict oil oxidation levels in an engine, given any running parameters.

Med fokus på fredssoldatens barn : En småskalig studie av hur barn och familj hanterat situationen i samband med en förälders utlandstjänst

The purpose of this essay was to study the family situation in connection to the absence of one parent due to participation in international peacekeeping and peace enforcement operations. Focus was on the temporarily absent parent's point of view. The study was based on five interviews with parents shortly after their returning home. The main questions has been how the parent described the child-parent relationship before, during and after the absence; the children's experience during this time according to the parent and the family's adjusting to and coping with the situation. Conclusions made from the study show that with a good stabile child-parent relationship and good parenting skills of both parents the families in this study were successful in coping with the situation.

Flavan-3-oler och endotel -dysfunktion

Background: Flavan-3-ols are polyphenolic phytochemicals belonging to the flavonoids. Flavan-3-ols are present in many higher plants and are particularly concentrated in e.g. Camellia sinensis (tea) and Theobroma cacao (cacao) and have got attention due to their antioxidative capacity. Many studies have been able to associate flavan-3-ol-rich foods to improved endothelial function. The aim of the present work is to review the scientific literature and evaluate the evidence for positive effects of flavan-3-ols on endothelial dysfunction in humans. Method: Scientific articles describing intervention and observational studies about flavan-3-ols and endothelial dysfunction, were searched for on http://www.pubmed.org.

Muddring i Ireån : indirekta effekter på bottenfaunan nedströms

This research aims to investigate the effects that dredging may have on benthic fauna. The dredging took place in the stream Ireån on northern Gotland during the early summer 2010. My area of research was taking place in a scenic area downstream in Ireån close to the Baltic Sea. I chose this area due to the dredging that started just upstream of this area and continued further upstream. Thus it is not the direct impact of the dredging that is the focus for this paper but the side-effect the dredging may have on the area downstream.

Socialt arbete med ensamkommande flyktingbarn : En kvalitativ studie om hur socialarbetare upplever det tvärkulturella arbetet med ensamkommande flyktingbarn

The purpose of this study was to examine how some social workers in Sweden describe the social work with unaccompanied children. Emphasis was on the role of culture in social work with the unaccompanied children. I wanted to examine how the social workers describe their view on social work with unaccompanied. I also wanted to examine how the social workers describe their view at their own and the unaccompanied children?s cultural backgrounds influence on the social work with the unaccompanied.

Introduktion till Certifierad Grafisk Produktion på Jernström Offset

The aim for this thesis was to develop a proposal of documentation, containing rules and procedures, which JernströmOffset needs to acquire the Certified Graphic Production certification. A fundamental part was to study the materialissued by Sveriges Grafiska Mediaförening, to clarify the requirements that must be met to obtain the certification. Therecommendations found in the CGP material must also be considered.Based on the requirements and recommendations of Certified Graphic Production, a mapping of the workflows atJernström Offset was performed. It was done by interviewing employees from different departments at the company,this to get a clear understanding of the operations carried out throughout the production flow and the final qualityfollow-up.During our reviewing process we found that a number of changes, in terms of working environment and practices,must be made at the company. As a result of this we propose some appropriate actions to be implemented.The documentation was finally written, through the requirements and recommendations of Certified GraphicProduction and then applied to Jernström Offset?s work procedures..

Varumärkesvänner och relationsreklam - En kvantitativ studie av medarbetarkommunikation på Facebook

Marketers of today are confronted by the fact that it is increasingly difficult to gain the customer's attention, as they first have to break through the ad clutter. In a landscape where the general attitude towards advertising is negative, one way to successfully deliver the message to the customer involves communicating through personal impact. By using stimuli containing identical information with different senders, this thesis seeks to quantitatively explore whether brands can make use of the personal networks of its employees, in their social media marketing strategy. The purpose of the study is to investigate if communication via the employees could enhance traditional communication effects, such as buying intention and electronic WOM intention. Furthermore, the study aims to examine which role the employee should hold when communicating on behalf of the brand, and if the communication effects vary with the degree of product involvement.

Sjuksköterskors erfarenheter av att uppmärksamma, bedöma och hantera somatiska symtom och problem i det psykiatriska omvårdnadsarbetet

Background:Patients with mental disabilities are more prone to somatic illnesses than the general public. Unhealthier lifestyles and side effects of medication might be causes of conditions that lead to diabetes, cardiovascular diseases and premature death. According to the Social Board patients with mental disabilities receive poorer treatment than patients with only somatic diagnosis.Aim:The aim of the study was to describe nurses' experiences to identify, assess and manage somatic symptoms and problems within the psychiatric care.Method:The study is based on interviews with 12 nurses working in psychiatric outpatient and inpatient care. A qualitative content analysis was chosen.Result:The nurses performed nursing through talking, blood sampling and measuring for example blood pressure. They followed up side effects of medication.

Informationsoperationer ? en amerikansk idé?

I USA infördes begreppet informationsoperationer i mitten av 1990-talet och det har sedan dess skett en stor utveckling inom detta fält. Även i den svenska Försvarsmakten har konceptetinformationsoperationer införts och en utveckling och uppbyggnad av förmågor inom detta koncept pågår. Syftet med denna uppsats är att undersöka huruvida konceptet informationsoperationers uppkomst i Försvarsmakten kan utgöra ett exempel på idéspridning. Utgångspunkten är att USA som en av världens ledande försvarsmakter är trendsättare för andra försvarsmakter i västvärlden, däribland den svenska Försvarsmakten. Med utgångspunkt i teorin om idéspridning undersöks om den amerikanska idén om informationsoperationer har spridit sig och snappats upp av Försvarsmakten som sedan översatt idén efter sina egna förutsättningar.

Singel eller Tillsammans?: En kvantitativ studie om effekterna av att göra reklam för flera produkter inom en produktkategori tillsammans

This paper quantitatively examines the effects of marketing brands within the same product category and the same brand portfolio jointly. We have chosen to call this type of marketing category advertising. The results of the study show that category advertising leads to increased brand awareness within the category, which is particularly important for brands within less salient subcategories. For strong brands however, category advertising leads to lower purchase intentions, an effect which could potentially be moderated by focusing the advertisement on the complementary nature of the products combined with promotional elements. The study also shows that there is no difference between advertising products jointly and separately when it comes to brand attitude, category attitude, typicality, brand purchase intention for weak brands and category purchase intention.

Spannmålsexport & exportsubventioner - hand i hand?

This thesis analyzes the effects of export subsidies on Swedish cereal export. The analyzes are based on data on cereal export from Sweden to countries outside the EU from 1990 to 2003. In 1995 Sweden became a member of the European Union. Before the membership, the Swedish agricultural policy was decoupled in a larger sense than the European CAP was, which means that the Swedish producers had decreased their production more than the European farmers. When Sweden became a member of the EU the production started to increase again to an EU level.

Arbetsmiljöekonomisk utvärdering av ergonomiförbättringar : Grundade i antaganden om sjukfrånvaro och förändring i arbetsbelastning efter intervention inom en avdelning i läkemedelsbranschen

The purpose of this study is to incrementally, through a combination of various methods, examine the assumptions about the working economic outcomes that can be made based on planned ergonomic intervention in a department at Pfizer Health AB in Strängnäs. The study contributes to knowledge about how assumptions on OSH financial results can be made, based on planned ergonomic interventions. These assumptions were based on biomechanical calculations made on the basis of ergonomics measurements with inclinometer. The study is important because previous research has shown that poor work environment have a bad impact on the economy of a company in different ways. It can for example be negative impact on the company's productivity and quality of the units produced or the services provided.
