CAD modelling of the human femur taking into account the structure of the bone
2021
The use of 3D models of the human bone system has great utility in the biomechanical study, due to the fact that these structures cannot be analyzed or tested in vivo. Within this paper, taking into consideration its real bone structure, the human femur CAD modelling is established. Firstly, a preliminary anatomical study is done, in order to highlight the fact that the thigh bone is a heterogeneous structure, consisting of several entities with different mechanical characteristics. The modelling starts from a homogenous 3D model of the femur, from which, every single separate entity is designed and finally they are assembled within a single product assembly. Therefore, the final result ens…
Development and Structure of Environmental Worries in Germany 1984–2019
2021
Abstract Referring to a survey question in the German socio-economic panel, which measures worries about protecting the environment, the article looks at the development of environmental worries in Germany for the timespan 1984–2019. The analyses mainly have descriptive character. We explore several expectations and assumptions discussed in historical accounts of the environmental movement in Germany and in empirical studies on environmental attitudes and their determinants. Results show that the overall development can be divided into a period of rising environmental worries in the 1980s, a considerable decline in the 1990s, and a relative stability since 2000. From 2018 to 2019, however, …
Becoming Dialogical: Psychotherapy or a Way of Life?
2011
After birth the first thing we learn is becoming a participant in dialogue. We are born in relations and those relations become our structure. Intersubjectivity is the basis of human experience and dialogue the way we live it. In this paper the dilemma of looking at dialogue as either a way of life or a therapeutic method is described. The background is the open dialogue psychiatric system that was initiated in Finnish Western Lapland. The author was part of the team re-organizing psychiatry and afterwards became involved in many different types of projects in dialogical practices. Lately the focus has shifted from looking at speech to seeing the entire embodied human being in the present m…
Is small and medium-sized beautiful? The structure and evolution of family SMEs research
2021
PurposeThe field of scientific research on small and medium-sized family businesses has been growing exponentially and the aim of this paper is to systematize the body of knowledge to develop an agenda for the future.Design/methodology/approachAdopting comparative bibliometric analyses on 155 articles (from 1989 until 2018) the authors provide a systematic assessment of the scientific research about small family firms, unveiling the structure and evolution of the field. Bibliographic coupling, co-citation analysis and co-occurrence analysis are adopted to identify the most influential studies and themes.FindingsFour clusters of research are reviewed: succession in family SMEs, performances …
ProteinScanAR - An Augmented Reality Web Application for High School Education in Biomolecular Life Sciences
2012
Understanding protein structures is a crucial step in creating molecular insight for researchers as well as students and pupils. The enormous scaling gap between an atomic point of view and objects in daily life hampers developing an intuitive relation between them. Especially for high school students, it can be difficult to understand the spatial relations of a protein structure. Due to lack of direct imaging techniques, molecules can only be explored by studying abstract molecular models. Here, the use of Augmented reality (AR) techniques has proven to strongly improve structural perception. In this work we present ProteinScanAR, an augmented reality framework for biomolecular education t…

Optimal Adaptive Inspection Planning Process in Service of Fatigued Aircraft Structures
2009
In this paper, a control theory is used for planning inspections in service of fatigue-sensitive aircraft structure components under crack propagation. One of the most important features of control theory is its great generality, enabling one to analyze diverse systems within one unified framework. A key idea, which has emerged from this study, is the necessity of viewing the process of planning in-service inspections as an adaptive control process. Adaptation means the ability of self-modification and self-adjustment in accordance with varying conditions of environment. The adaptive control of inspection planning process in service of fatigued aircraft structures differs from ordinary stoc…
What Makes a Text Easy or Difficult to Understand?
1989
Abstract The question of what makes a text easy or difficult to comprehend is answered on the basis of an empirical investigation, which draws especially on theories related to text and memory linguistics. Easy and difficult texts, verified empirically, were analyzed on micro‐ and macro‐levels. Certain aspects of syntax, lexicon and information structure were first studied. These were followed by text‐level analyses related to the narrative and structural organization and the propositional structure of the texts. The article gives an account of the parameters that were most clearly associated with level of text comprehension. The results are also discussed in the light of the possible impli…
In Itinere STRATEGIC ENVIRONMENTAL ASSESSMENT of an integrated provincial waste system
2009
In the paper, the practical problem of analysing in an integrated way the performance of provincial waste systems is approached, in the framework of the Strategic Environmental Assessment (SEA). In particular, the in itinere phase of SEA is analysed herein. After separating out a proper group of ambits, to which the waste system is supposed to determine relevant impacts, pertinent sets of single indicators are proposed. Through the adoption of such indicators the time trend of the system is investigated, and the suitability of each indicator is critically revised. The structure of the evaluation scheme, which is essentially based on the use of ambit issues and analytical indicators, calls …
Dialog Structure Automatic Modeling
2010
This paper presents the approach implemented as part of a conversational bot named WIH (Word Intelligent Handler). It has a complex architecture with several components. Some of them are the ER-memory, EP-memory and other minor modules that provide the prototype of good modeling of Spanish sentences. They constitute the knowledge-representation mechanism that is used by WIH to build automatic answers during dialogs with humans. In this paper a small description of these components and some of its interaction is given, along with test cases and a statistical analysis of the results obtained. It is shown here that WIH prototype can adapt its behavior and learning rate of its internal working …
