TORSIONAL STRESS CONCENTRATIONS IN SHAFTS: FROM ELECTRICAL ANALOGIES TO NUMERICAL METHODS
2013
This paper presents the historical development of methods used for the study of torsional stresses in shafts. In particular the paper covers both analog methods, in particular those based on electrical analogies proposed since about 1925, and numerical methods, in particular finite difference methods (FDM), finite element methods (FEM) and boundary elements (BEM).
The transformation of a building of the 1970s into a contemporary sustainable building in the Mediterranean Basin
2008
The paper shows the design strategies adopted by a group of graduands of the Faculty of Building Engineering at the University of Palermo involved in a research project aimed to analyse the problems related to the renovation of modern buildings and to solve them by using sustainable approach. In particular, the aim of the research is to investigate these problems in the context of the Mediterranean Basin by adopting, when possible, design criteria inherited by the traditional architecture where sustainable design strategies were used unconsciously. The graduands thesis consists in the transformation of Mazara City Hall into the new "Satiro Danzante Museum" by using natural ventilation syste…
Identification of Synaptic Integration Mode in CA3 Pyramidal Neuron Model
2019
International audience; A morphologically realistic and anisotropic model of CA3 pyramidal neuron was developed to determine the synaptic integration modes the neuron is able to perform. Linearity and nonlinearity were identified in different synaptic locations with varying active mechanisms such as the presence of ionic channels in the dendritic arbor and the types of receptors in the synapse. Quantification of synaptic integration was performed using paired-pulse stimulation protocol and subthreshold input/output (sI/O) transformation. Results show that the mode of synaptic integration is location-dependent while the linearity or nonlinearity in the integration is mainly influenced by the…
Computer Aided Optimization Via Simulation Tools of Energy Generation Systems With Universal Small Wind Turbines
2012
This paper considers the general issues in the project and the optimization of energy generation systems using small universal wind turbines, suitable in Distributed Generation (DG) and computer aided optimization for a better exploitation of wind source. Optimization in this field reveal to be more and more important because the local generation and consumption of electrical power, even for grid connected generators can suffers for unevenness of wind source exploitation, also in terms of wrong directions and in not regular wind flows. Computer aided design and optimization of small plants may give significant improvements in the development of the wind source also in accordance with the pr…
