Treatment technology for leachate from faecal sludge drying beds

The use of planted drying beds for faecal sludge treatment is effective for solid-liquid separation, but the leachate produced requires further treatment prior to discharge or reuse. This study investigates the potential of a new and low-cost solution for leachate treatment

Feature Extraction and Static Analysis for Large-Scale Detection of Malware Types and Families

There exist different methods of identifying malware, and widespread method is the one found in almost every antivirus solution on the market today; the signature based approach. This approach uses a one-way cryptographic function to generate a unique hash of each file. Afterwards, each hash is checked against a database of hashes of known malware. This method provides close to none false positives, but this does also mean that this approach can only detect previously known malware, and will in many cases also provide a number of false negatives. Malware authors exploit this weakness in the way that they change a small part of the malicious code, and thereby changes the entire hash of the file, which then leaves the malicious code undetectable until the sample is discovered, analyzed and updated in the vendors database(s). In the light of this relatively easy mitigation for malware authors, it is clear that we need other ways to identify malware. The other two main approaches for this are static analysis and behavior based/dynamic analysis. The primary goal of such analysis and previous research has been focused around detecting whether a file is malicious or benign (binary classification). There has been comprehensive work in these fields the last few years. In the work we are proposing, we will leverage results from static analysis using machine learning methods, to distinguish malicious Windows executables. Not just benign/malicious as in many researches, but by malware family affiliation. To do this we will use a database consisting of about of 330.000 malicious executables. A challenge in this work will be the naming of the samples and families as different antivirus vendors labels samples with different names and follows no standard naming scheme. This is exemplified by e.g. the VirusTotal online scanner which scans a hash in 57 malware databases. For the static analysis we will use the VirusTotal scanner as well as an open source tool for analyzing portable executables, PEframe. The work performed in the thesis presents a novel approach to extract and construct features that can be used to make an estimation of which type and family a malicious file is an instance of, which can be useful for analysis and antivirus scanners. This contribution is novel because multinominal classification is applied to distinguish between different types and families

Anchor Handling Tug Supply : Is there a correlation between fuel consumption and rate levels?

The last four years have seen offshore vessel owners struggle with declining utilization and revenues from their fleet. Reducing the cost of operation have been the focus for survival, second only to securing capital expenditure runway. Where other offshore segments have seen a clear favouritism from oil companies, hiring and advocating for vessels with more fuel and cost-efficient profiles, the powerful and complex AHTS vessels have been lacking a similar seen focus. This thesis has studied the variance between consumption and rate levels for the large sized AHTS vessels. Through statistical analysis and regressions, it sought to determine a correlation between consumption profile and rate levels earned, both from an overall perspective, and during power distribution favouring either buyer or seller, in geographical specified areas of operation. Interviews with eight relevant industry professionals were in addition conducted, to strengthen the quantitative results together with evaluating and connecting relevant literature on the subject. The overall results found that the fuel consumption has played a diminutive part in determining rate levels for these vessels. Indications where found supporting a positive correlation between less fuel consuming vessels and rates, when buyer’s bargaining power was strong. For the area specific research, the South American and Australian covered areas reflected to be the regions with the strongest consumption focus and rate correlation. Respondents were found to diverge in their expressed views, with oil companies more inclined to support a fuel efficient AHTS’s positive influence on rates, while owners expressed little confidence in consumption significantly affecting rates

Dissociative identity disorder: Integration versus non-integration

For the mental health professional, the client with Dissociative Identity Disorder (DID) can be exciting, exhausting and frustrating. Formal education offers little help in treatment and diagnosis of this disorder. This paper will explore the most utilized treatment goals available to the professional and the client. Although most experts in the field of Dissociative Disorders subscribe to the treatment goal of integration, this study challenges that idea. As the results of the study indicate, integration was not the most utilized goal of treatment among the participants of this study

The Effect of Deformation by Torsion and Subsequent Heat Treatment on the Microstructure of AA6082

An AA6082-aluminum alloy is used in the production of suspension components for cars at Raufoss Technology AS. The components are manufactured through a process of several forming and heating steps. Through torsion testing with subsequent heat treatment, it has been found that the alloy is susceptible to recrystallization during heat treatment following deformation. A linear relationship between the heat treatment temperature and Zener-Hollomon parameter Z and risk of recrystallization is proposed. This relationship suggests that there is a risk of a recrystallized microstructure after post-deformation heat treatment at temperatures above T_(heat treatment) [℃]=1355-30×ln⁡Z. The flow properties of the material during hot working conditions were examined by torsion testing. Constitutive relations are suggested based on the recorded experimental stress-strain curves and strain rate and deformation temperature measurements. The activation energy for hot work is estimated to be Qhw = 170 kJ/mol for the alloy. The experimental data are found to deviate from the suggested constitutive relations at low deformation temperatures (T = 350℃ and T = 400℃) and shear strain rates below 1 s-1. The constitutive relations are generally found to correlate with the experimental data at higher strain rates and deformation temperatures

English as Path and Barrier: A Comparative Case Study of Refugee Education Policies in Uganda, Rwanda, Tanzania, and Ethiopia

På grunn av økt tvungen migrasjon og en vedvarende politikk for bruk av eksoglossiske undervisningsspråk i afrikanske land, er det et stort behov for videre forskning på hvordan utdanning for elever med flyktningbakgrunn best kan tilrettelegges. Denne oppgaven bidrar til det lite utforskede feltet rundt bruk av engelsk som undervisningsspråk i grunnskoleopplæring for flyktninger, gjennom en komparativ casestudie av språkforskrifter for flyktninger i Uganda, Rwanda, Tanzania og Etiopia. Casestudien anvender et perspektiv basert på lingvistisk neoimperialisme for å få en dypere forståelse av «hvordan og hvorfor» disse språkforskriftene har utviklet seg som de har, samt for å svare de økende utrop om dekolonisering av engelskundervisning. Funnene i denne oppgaven er verdifulle for å informere fremtidige tilnærminger til opplæring i engelsk som andrespråk, både for lærere og beslutningstakere, ved å gi økt innsikt i de respektive rollene til engelsk, hjemmespråk og flerspråklighet i flyktningopplæring i Uganda, Rwanda, Tanzania og Etiopia. Oppgaven finner en tendens til å betrakte engelsk som kunnskapens lingua franca, gjennom å etablere engelsk som undervisningsspråk i høyere utdanning. Denne posisjoneringen fører til økende bruk av engelsk i grunnskolen, og resulterer i en dobbeltsidig rolle der engelsk både fungerer som en vei inn i og en barriere mot utdanning. Oppgaven peker også på mangel på empirisk forskning med utgangspunkt i flyktningers egne perspektiver, og understreker behovet for mer kontekstnær forskning på de levde konsekvensene av disse språkpolitiske føringene. Til slutt fremhever oppgaven nødvendigheten av at norske engelsklærere får økt forståelse for hvilken rolle både hjemmespråk og tidligere undervisningsspråk spiller i det språklige repertoaret til elever med flyktningbakgrunn.In light of increased forced migration and a continued use of exoglossic mediums of instruction in African countries, there is a major need for further research on how to better facilitate education for students with refugee bakground. This thesis contributes to the underexplored field of English as a medium of instruction in primary refugee education through a comparative case study of refugee education policies in Uganda, Rwanda, Tanzania, and Ethiopia. The case study implements the lens of linguistic neo- imperialsim to gain a deeper understanding of “how and why” these policies have evolved as they have, and as a response to the increaing calls of decolonising the EAL field. The findings of this thesis are valuable in informing future approaches to EAL education, both for teachers and policy makers, through a further understanding of the respective roles of English, home languages, and multilingualism in Ugandan, Rwandan, Tanzanian, and Ethiopian refugee education. The study finds a tendency of viewing English as the lingua franca of knowledge, as it is implemented as the medium of instruction in higher education. This postitioning leads to increased roles of English in primary education, resulting in the duality of English as both a path and a barrier to education. The thesis also points to a lack of empirical research from refugee perspectives, urging further contextual research on the lived implications of these polices. Lastly, the thesis notes the need for Norwegian EAL teachers to further understand the role home languages and previous mediums of instruction have in the linguistic repertoires of students with refugee background
