Influence of Heat Treatment on Fatigue Crack Growth in Ti-6Al-4V Alloy
2011
The paper contains the results of experimental work carried out in order to analyse the initiation and propagation of fatigue cracks in Ti-6Al-4V titanium alloy. The tests were performed on plane specimens with the stress concentrators in form of one-sided sharp notches. The tested specimens were made of the oxygenated Ti-6Al-4V subjected to various variants of heat treatment.
Low Urethral Pressure Profile - Clinical Implications
2001
The clinical impact of urethral pressure profilometry (UPP) has been a main urological topic over the past three decades. Exaggareted expectations and differing techniques with incongruent results caused a controversial appearance. However, since the UPP is the only method to measure directly aspects of the urethral closure function, all types of sphincteric urinary incontinence represent indications for this measurement. Based on long-term experience this paper aims to discuss the various complexes regarding the urethral pressure profilometry. The significance of the urethral closure function for urinary continence and the urodynamic relevance of active and passive pressure transmission ar…
Rural Municipalities and Change in Local School Structure: Comparing Room of manoeuvre among Rural Municipalities in Latvia and Norway
2018
Rural depopulation, decreasing numbers of children and general centralization combined with high expectations to education, are factors that challenge rural communities and school structures in Latvia and Norway. The ambition of this article is to explore and compare the role of the municipality and other levels of governance in making decisions on school structure in rural municipalities. The research method is a multiple case study approach, supported by survey data. Through the lenses of multi-level governance theory, we have investigated how national frames like regulations and educational expectations are affecting local decision-making. Local politicians navigate between national fram…
A multi objective genetic algorithm for the facility layout problem based upon slicing structure encoding
2012
This paper proposes a new multi objective genetic algorithm (MOGA) for solving unequal area facility layout problems (UA-FLPs). The genetic algorithm suggested is based upon the slicing structure where the relative locations of the facilities on the floor are represented by a location matrix encoded in two chromosomes. A block layout is constructed by partitioning the floor into a set of rectangular blocks using guillotine cuts satisfying the areas requirements of the departments. The procedure takes into account four objective functions (material handling costs, aspect ratio, closeness and distance requests) by means of a Pareto based evolutionary approach. The main advantage of the propos…
Multiple Hypotheses Testing
1993
The paper is mainly concerned with multiple testing procedures which control a given multiple level α. General concepts for this purpose are the closure test and a modification which is independent of the special structure of hypotheses and tests. We consider improvements of this modification using information about the logical dependences (redundancies) within the system of hypotheses and present an efficient algorithm. Finally, we discuss some problems which are specific for hierarchical systems of hypotheses, e.g. in model search.
School adjustment in children who stutter: The quality of the student-teacher relationship, peer relationships, and children's academic and behaviora…
2020
Abstract Introduction The aim of this study was to investigate the quality of the student-teacher relationship, peer relationship, emotional and behavioral outcomes and academic performance in school adjustment of children who stutter. Methods The convenience sample consisted of 536 children – 62 affected by stuttering and 474 in the control group – and 36 prevalent teachers from six primary and secondary schools in Northwest Italy. Children were assessed with a sociometric questionnaire. Teacher evaluations were also used to assess their perception of their relationships with the student (Student-Teacher Relationship Scale), children’ behavior (Strengths and Difficulties Questionnaire), an…
On the category Set(JCPos)
2006
Category Set(JCPos) of lattice-valued subsets of sets is introduced and studied. We prove that it is topological over SetxJCPos and show its ''natural'' coalgebraic subcategory.
Nörttikulttuurin identiteettikriisi
2020
Nörttikulttuuri on identiteettikriisissä. Perinteisesti nörttimäisinä pidetyt käytänteet ja kulttuurituotteet ovat siirtyneet lähemmäs valtavirtaa, mikä on häivyttänyt rajaa nörttien ja muiden median ja teknologian käyttäjien välillä. Nörttikulttuurin sisälle tämä on heijastunut kiistaksi siitä, kuka saa osallistua nörttikulttuurin kuluttamiseen, tuottamiseen ja määrittelyyn, ja millä tavoin. Stereotypia nörttikulttuurista valkoisten heteromiesten maskuliinisena kenttänä ei koskaan ole pitänyt täysin paikkansa, mutta 2000-luvulla väitteen totuudellisuus on murentunut entisestään.
 Tässä artikkelissa tarkastelemme nörttiyden kriisiä kolmen tapaustutkimuksen kautta ja analysoimme, mitä G…
Impact of reverse logistics on supply chain performance
2013
Purpose – The purpose of this paper is to analyse the impact of reverse logistics on order and inventory variance amplification in a single-echelon supply chain (SC) and to propose a new order policy for dampening such amplification. Design/methodology/approach – A general review of the literature on sustainable operations and on the impact of reverse logistics on SC performance provides the foundation for the study. The authors use difference equation math approach for modelling and analysing a closed SC. A proper design of experiment and data collected from the European Union statistics validate the obtained numerical results. Findings – The variability of reverse flow in a closed loop S…
Algorithms for the calculation of the view factors between human body and rectangular surfaces in parallelepiped environments
1992
Abstract The thermal comfort conditions for people in moderate thermal environments are subjected to spatial changes, depending on the radiative exchanges of the human body with the surrounding surfaces. Radiative thermal exchanges are notably accounted for by means of the “view factors” between a person in a given posture and the surface of the enclosure. These important parameters can be evaluated by means of a large set of graphs by Fanger, for rectangular surfaces. But the handling of graphs could lead to reading errors. In this paper a simple algorithm is presented, which is able to compute the required view factors. A validation, by means of a comparison against experimental data, is …
