Theoretical-Applicative Research on Design and Implementation of a Special Dynamometer
2013
The topic of he present paper is taken from the Automotive Systems Nurnberg, Sibiu. It refers to the product automatic gear box which equips a few FORD models, the specific part for which the research was developed being a auto screwing bolt for plastic which raises problems at the robotized screwing because of the poor knowledge of the accurate value of the axial force and the necessary torque.
Management performance of telework teams based on experimental methods
2009
This paper seeks to answer the following two questions: Which management factors have great effect on the management performance of telework teams? and How should management choose suitable team members for telework? The research will use experimental methods for exploring the novel topic of management performance of telework teams. The experimental design, implementation and result analysis will be done by using a computer experimental system we developed. The experimental research results show that an effective way of improving management performance of telework teams relates to the positive and the negative degrees of psychological factors, team factors, ethical factors and individual ba…
Applicability of over-coring technique to loaded RC columns
2014
Stress determination is a very important step in the assessment of the safety of existing reinforced concrete structures. In rock mechanic this goal is achieved with the over-coring technique. The main idea behind such a technique is to isolate a material sample from the stress field in the surrounding mass and monitor its re-equilibrium deformation response. If the materials remains elastic, and elastic properties are known, stresses may be obtained from the corresponding measured strains. The goal of this paper is to evaluate if the over-coring technique is applicable to reinforced concrete members. The results of an experimental investigation on the behaviour of compressed concrete colum…
The experimental research strategy of the endmilled aluminum alloys
2017
In this paper, the most important aspects of the research methodology of the resulted surface quality by aluminum alloys endmilling, are presented. The first part of the paper includes a short presentation of the cutting processes aluminum alloys evolution. In the second part, the research problem was defined by setting a fundamental objective and identifying the specific objectives which contribute to achieve the fundamental objective. In this context an experimental study, was performed, starting with the organization and conducting the endmilling process, in which the cutting regime were established, then the characteristic measured parameters were determined, so that the research factor…
Experimental Research of Thermal Comfort Conditions in Small Test Buildings with Different Types of Heating
2015
Abstract The aim of this study is detailed analysis of long-term monitoring data of thermal comfort conditions and energy efficiency in small test buildings equipped with different heating systems. Calculations of PPD index and local thermal discomfort factors are provided for the test buildings during three weeks of heating season. It is shown that the type of heating system has influence not only on heating energy need, but also on thermal comfort conditions in the room.
Dependence of fracture toughness of composite laminates on interface ply orientations and delamination growth direction
2004
A critical review has been performed of the published experimental research concerning delamination onset and growth in composite laminate interfaces of different lay-ups under single-mode loadings. It was found that, depending on the loading mode and interface lay-up, the traditional fracture toughness characterization by unidirectionally reinforced composite tests can lead to marked under- or overestimation of material resistance to crack growth. Empirical models of fracture toughness as a function of delamination front orientation with respect to reinforcement directions of the adjacent laminae have been validated and their applicability range established.
Model to Assess the Quality of Magmatic Rocks for Reliable and Sustainable Constructions
2017
Geomechanical assessment of rocks requires knowledge of phenomena that occur under the influence of internal and external factors at a macroscopic or microscopic scale, when rocks are submitted to different actions. To elucidate the quantitative and qualitative geomechanical behavior of rocks, knowing their geological and physical–mechanical characteristics becomes an imperative. Mineralogical, petrographical and chemical analyses provided an opportunity to identify 15 types of igneous rocks (gabbro, diabases, granites, diorites, rhyolites, andesites, and basalts), divided into plutonic and volcanic rocks. In turn, these have been grouped into acidic, neutral (intermediate) and basic magmat…
Uterine transplantation: one human case followed by a decade of experimental research in animal models
2011
Uterine transplantation (UTx) aims to treat unconditional uterine factor infertility by replacing a non-functioning or non-existing uterus. After one attempt of UTx in the human 10 years ago, intensive research has been performed. The results of these specific studies on surgical technique, ischaemia-reperfusion injury, immunosuppression and fertility are discussed.
Work-Related Stress, Physio-Pathological Mechanisms, and the Influence of Environmental Genetic Factors
2019
Work-related stress is a growing health problem in modern society. The stress response is characterized by numerous neurochemicals, neuroendocrine and immune modifications that involve various neurological systems and circuits, and regulation of the gene expression of the different receptors. In this regard, a lot of research has focused the attention on the role played by the environment in influencing gene expression, which in turn can control the stress response. In particular, genetic factors can moderate the sensitivities of specific types of neural cells or circuits mediating the imprinting of the environment on different biological systems. In this current review, we wish to analyze …
Business competencies and innovation capability in cross-border small regional enterprises
2017
This paper explores the socio-economic aspects of human capital, especially the IT users' innovation capability in regional cross-border small and medium-sized enterprises in Poland and in Germany. Socio-economic aspects of human capital are crucial for the socioeconomic development that may be achieved through virtual access to online learning tools and by diagnosing IT users' innovation capability and their business competencies, in relation to information and communication technologies. This paper presents an initial report on experimental research that was conducted online using the author's diagnostic tools. Conclusions and findings of this work contribute to socioeconomic development …
