Hybrid prediction-optimization approaches for maximizing parts density in SLM of Ti6Al4V titanium alloy
2022
AbstractIt is well known that the processing parameters of selective laser melting (SLM) highly influence mechanical and physical properties of the manufactured parts. Also, the energy density is insufficient to detect the process window for producing full dense components. In fact, parts produced with the same energy density but different combinations of parameters may present different properties even under the microstructural viewpoint. In this context, the need to assess the influence of the process parameters and to select the best parameters set able to optimize the final properties of SLM parts has been capturing the attention of both academics and practitioners. In this paper differ…
Leilighetskompleks i små lokalsamfunn- virkninger i eiendomsmarkedet : en analyse basert på data fra Egersund
2009
Masteroppgave i økonomi og administrasjon - Universitetet i Agder 2009 Hensikten med oppgaven er å undersøke boligmarkedet i Egersund, og virkningene av bygging av større leilighetskomplekser. Bygging av leiligheter har økt de siste årene, og utgjør i dag 21,9 % av det totale boligmarkedet. Spesielt i større byer har det vært mye bygging av leiligheter. Denne trenden finnes nå også i mindre byer. På bakgrunn av teori har jeg utledet en prisfunksjon. Denne gir prisen som en funksjon av de ulike egenskapene til boligene. Funksjonen dannes på bakgrunn av etterspørrernes etterspørselsfunksjoner og tilbydernes tilbudsfunksjoner. En prisfunksjon kan anta ulike former. Jeg har valgt å se nærmere p…
Predicting women purchase intention for green food products in Indonesia
2009
Masteroppgave i økonomi og administrasjon - Universitetet i Agder 2009 This study investigated the applicability of the Theory of Planned Behavior in predicting women consumers on their intention towards purchasing green food products among 406 participants. Using linear regression, five independent variables had been examined: attitude towards green food products, subjective norms, perceived behavioral control, and perceived difficulty in predicting purchase intention. The results reveal further evidence of consistency between Attitude, Subjective Norm, Perceived Behavioral Control and Perceived Difficulty as presented in Theory of Planned Behavior. Despite the supporting evidence for the …
Rejection odds and rejection ratios: A proposal for statistical practice in testing hypotheses
2016
Much of science is (rightly or wrongly) driven by hypothesis testing. Even in situations where the hypothesis testing paradigm is correct, the common practice of basing inferences solely on p-values has been under intense criticism for over 50 years. We propose, as an alternative, the use of the odds of a correct rejection of the null hypothesis to incorrect rejection. Both pre-experimental versions (involving the power and Type I error) and post-experimental versions (depending on the actual data) are considered. Implementations are provided that range from depending only on the p-value to consideration of full Bayesian analysis. A surprise is that all implementations -- even the full Baye…
A test of water pouring height and run intermittence effects on single-ring infiltration rates
2018
Assessing how the infiltration process depends on the water impact energy improves interpretation of hydrological processes. Impact energies vary with the height of water pouring; that is, the distance between the water delivery point and the soil surface. The effects of the height of water pouring on infiltration in an initially near saturated soil can be tested in the field by two repeated Beerkan infiltration runs separated by a short pause (30 min) and using both low (non-perturbing) and high (perturbing) heights of water application. The double two-stage Beerkan run methodology was applied in two soils. The infiltration rate at the end of the perturbing stage of the experiment was 0.2–…
Water transmission properties of a sandy-loam soil estimated with Beerkan runs differing by the infiltration time criterion
2021
Abstract The Beerkan method consists of a ponded infiltration experiment from a single ring inserted a small depth into the soil. Fixed, small volumes of water are repeatedly poured into the ring to maintain a quasi-zero head on the soil surface. According to the standard Beerkan infiltration run, a new water volume is poured on the infiltration surface when the previously applied volume has completely infiltrated and the soil surface is entirely exposed to air (ta criterion). However, water could also be applied when the soil exposition to air begins (to criterion) or half the soil surface is exposed to air (tm criterion). The effect of the infiltration time criterion on determination of t…
Waging War Against Mechanical Man. Frank H. Knight's Critique of Behavioristic Psychology
2002
The major theme of this essay is to explore the rationale of Knight's campaign against the adoption of behaviorism in economics. We also attempt to qualify whether Knight's methodological criticism may somewhat undermine his recently acquired credentials as an institutionalist economist. In so doing we focus our attention in particular, but not exclusively, on his debate with the institutionalist Morris A. Copeland. In the first section we try to explain why behaviorism gained consensus among institutional economists, and we also provide a brief overview of the main behavioristic themes as they were presented in contemporary economic literature. The second section is devoted to Knight's rea…
Intellectual capital reporting: A knowledge tool to coordinate a group of regional non-profit organisations
2017
Whilst many organizations worldwide have stopped disclosing Intellectual Capital (IC), to the best of our knowledge, the only longstanding NPO still measuring, managing and reporting its IC is a large Italian non-profit organization (NPO), ANPAS Piemonte. The main aim of the article is thus to investigate the reasons why ANPAS Piemonte continues to deal with IC, to examine the determinants of this choice, the costs and the benefits management gets from IC measurement, management and reporting. In other words, the paper aims to explore the intellectual capital (IC) reporting process from an internal, managerial point of view. The paper employ a case study methodology to address its aim, and …
Metaphysics of cosmological models
2023
This article aims to address the metaphysical dimension of cosmological models, be they mythological, philosophical, religious or modern scientific models, using multidisciplinary and transdisciplinary methodology. Such an approach is a novelty, both in the theological field and in the philosophical field and secular sciences, which studies the origin of humans and the universe. Contribution: The originality of this article consists in introducing the concept of transcendental cosmology, which, along with spiritual cosmology, can be a serious theological and philosophical reply to the Bing Bang theory.
Six Sigma in small- and medium-sized enterprises: a Black Belt project in the Swedish steel industry
2014
Many big companies around the world have solid Six Sigma infrastructures and it is easy to find in literature successful case studies. Conversely, small and medium-sized enterprises (SMEs) generally suffer lower attention in the literature. This happens because SMEs have only recently approached the methodology; they have weaker connection with the academia; or they do not rigorously pursue the frameworks. This paper is based on a Six Sigma project in a Swedish medium-sized company that produces steel tubes mainly for hydraulic applications. The project focused on the improvement of warehouse activities related to cutting processes. This Black Belt project was part of a Six Sigma education …
