Timing the US Stock Market Using Moving Averages and Momentum Rules: An Extensive Study
2017
Master's thesis Business Administration BE501 - University of Agder 2017 In this thesis we investigate the performance of moving average and momentum strategies by simulating returns, both in-sample and out-of-sample, while simultaneously taking into account important market frictions. We do so for two stock indices and four stock portfolios, at daily and monthly frequency, in the period from 1928 to 2015. This is carried out in order to examine if the active strategies outperform the passive benchmark on a risk-adjusted basis, and to see if the trading rules pro table when tested in-sample also are pro table out-of-sample. In addition, and for the rst time, we examine the relevance of data…
Potential for Usage of Thermoelectric Generators on Ships
2010
Published version of an article from the journal: Journal of Electronic Materials. he original publication is available at Springerlink. http://dx.doi.org/10.1007/s11664-010-1189-1 The useful waste heat potential for a bulk carrier has been evaluated as a preliminary step towards developing a thermoelectric generator (TEG) waste heat recovery system for ships. A medium-sized bulk carrier produces 6.2 MW of waste heat, and the most promising usable sources for the TEG are shown herein to be the exhausts from the main engine and the sludge oil incinerator.
Managing HMI utilities for control systems
2007
Masteroppgave i informasjons- og kommunikasjonsteknologi 2007 – Høgskolen i Agder, Grimstad The supervisor of this project, Origo Engineering AS delivers complete control and automation systems for the oil industry and smelting plants. Each hardware and software package is custom‐made. A part of the functionality is implemented by scripts – small programs that are coded and run directly on a Human Machine Interface (HMI) server. This method has some challenges, which are listed and further described in this report. Those challenges increase the time and cost of producing the control and automation system. The purpose of this master thesis is to design a solution that will solve those challe…
Enterprise content management: an analysis of contemporary practice and its relationships with enterprise architecture
2012
Masteroppgave i informasjonssystemer- Universitetet i Agder, 2012 Enterprise Content Management (ECM) consists of a wide set of interrelated issues, and previous research on ECM points out that there is a lack of a common understand of the concept itself. Further, there is a lack of a holistic approach to ECM and initiatives are often individual initiatives covering sub-parts of ECM. Organizations seem to have a more functional approach to ECM. Enterprise architecture (EA) is a concept which promises to provide a holistic and long-term view of a company’s processes, systems, and technologies so that individual projects can build capabilities – not just fulfill immediate needs. EA also promi…
Evaluating the effect of mineralogy and mechanical stability of recycled excavation materials by Los Angeles and micro-Deval test
2021
This paper presents the findings of the mechanical performance of recycled excavation materials (REM). The aim was to document the stable performance of REM and to suggest its suitability for unbound applications. Test operations were performed at different schedules with the Los Angeles (LA) and micro-Deval (MD) test machine. X-ray diffraction (XRD) analysis was performed to examine the effect of mineralogy on the performance of REM. The results showed that REM showed consistent LA performance, but significant variations were observed in MD values. XRD results showed that up to 20% of chlorite and mica minerals had no influence on the LA performance of REM.
Speciālā lietojuma valodas tekstu tulkošana: atšķirības starp juridiskajiem un tehniskajiem tulkojumiem
2021
Speciālā lietojuma valoda (SLV) pēta konkrētas profesionālās jomas valodu, tādēļ attiecīgajās jomās profesiju pārstāvji to izmanto kā darbarīku. Augsti pieprasītas jomas, kurās ir nepieciešams pārzināt SLV, ir tiesību zinātne un tehnoloģijas. Minētajās profesijās juridisko un tehnisko tekstu tulkošana ir ļoti nepieciešama jomu vispusības un starptautiskuma dēļ. Šī iemesla dēļ šī darba mērķis ir identificēt SLV tekstu tulkošanas īpatnības un definēt juridisko un tehnisko tulkojumu atšķirības, analizējot no latviešu uz angļu valodu iztulkotus juridiskos un tehniskos tekstus. Pētījuma jautājums tika izvirzīts, lai izpētītu SLV tekstu tulkošanas īpatnības un noteiktu atšķirības starp juridiskaj…
Comparing indoor performances of a building equipped with four different roof configurations in 65 Italian sites
2020
Abstract—Despite the increasing concern of institutions and technical organizations toward the improvement of the building energy (and, therefore, environmental) efficiency, the main goal of technicians should be also devoted toward the levels of internal thermal comfort that buildings are able to realize. As that, the relationships between energy performances and comfort conditions provided by the enclosures are of paramount importance in guiding designers in their work. In this paper, the influence of diverse roof construction typologies on energy and indoor performance of buildings has been investigated, in different Italian sites during heating and cooling seasons. In addition, it must …
Transition to distributed energy generation in Finland: Prospects and barriers
2015
Abstract Small-scale distributed energy generation is expected to play an important role in helping Finland increase its energy self-sufficiency. However, the overall strategy to date for promoting distributed energy remains unclear. It is not yet well understood which factors promote the growth of the distributed energy sector and what barriers need to be removed. In this article we present the results of a questionnaire directed at a panel of 26 experts from the distributed energy value chain and 15 semi-structured interviews with industry and non-industry representatives. We investigated, from a sociotechnical transition perspective, the possibilities and challenges of the transition to …
Robust H∞ sliding mode control with pole placement for a fluid power electrohydraulic actuator (EHA) system
2014
Published version of an article in the journal: International Journal of Advanced Manufacturing Technology. Also available from the publisher at: http://dx.doi.org/10.1007/s00170-014-5910-8 In this paper, we exploit the sliding mode control problem for a fluid power electrohydraulic actuator (EHA) system. To characterize the nonlinearity of the friction, the EHA system is modeled as a linear system with a system uncertainty. Practically, it is assumed that the system is also subject to the load disturbance and the external noise. An integral sliding mode controller is proposed to design. The advanced techniques such as the H ∞ control and the regional pole placement are employed to derive t…
Full-Waveform Terrestrial Laser Scanning for Extracting a High-Resolution 3D Topographic Model: a Case Study on an Area of Archaeological Significance
2014
AbstractThis paper describes a method, which uses full-waveform terrestrial laser scanning to survey the surface of the slope below the Temple of Juno, located in the Valley of the Temples in Agrigento (Sicily, Southern Italy). The surface is characterized by the presence of large rock blocks, which have fallen down from the upper side; possible further detachments of rock blocks would cause a situation of general instability, with a very high risk to the archaeological structures in the near future. The methodology was designed to evaluate the potential of full-waveform laser scanning technology for the production of a very high resolution 3D topographic model of the slope, to be used as a…
