On the Proper Homotopy Invariance of the Tucker Property

引用

Acta Mathematica Sinica,English Series 2007年第3期23卷 571-576页

作者： daniele Ettore OTERA Universitádi Palermo Dipartimento di Matematica ed Applicazionivia Archirafi 3490123-PalermoItaly and Université Paris-SudMathématiquesBt 42591405 Orsay Cedex-France

A non-compact polyhedron P is Tucker if, for any compact subset K begong to P, the fundamental group π1 （P - K） is finitely generated. The main result of this note is that a manifold which is proper homotopy equivalent to a Tucker polyhedron is Tucker. We use Poenaru＇s theory of the equivalence relations forced by the singularities of a non-degenerate simplicial map.

Influence of Process Parameters and Sr Addition on the Microstructure and Casting Defects of LPDC A356 Alloy for Engine Blocks

引用

Journal of Materials Science & Technology 2016年第6期32卷 515-523页

作者： Giulio Timelli daniele Caliari Jovid Rakhmonov Department of Management and Engineering University of PadovaStradeUa S.Nicola3 1-36100 VicenzaItaly

The effects of Sr addition and pressure increase on the microstructure and casting defects of a low-pressure die cast （LPDC） AISi7Mg0.3 alloy have been studied. Metallographic and image analysis techniques have been used to quantitatively examine the microstructural changes and the amount of porosity occurring at different Sr levels and pressure parameters. The results indicate that an increase in the filling pressure induces lower heat dissipation of the liquid close to the die/core surfaces, with the formation of slightly greater dendrite arms and coarser eutectic Si particles. On the other hand, the increase in the Sr level leads to finer microstructural scale and eutectic Si. The analysed variables, within the experimental conditions, do not affect the morphology of eutectic Si particles. Higher applied pressure and Sr content generate castings with lower amount of porosiW. However, as the filling pressure increases the flow of metal inside the die cavity is more turbulent, leading to the formation of oxide films and cold shots. In the analysed range of experimental conditions, the design of experiment methodology and the analysis of variance have been used to develop statistical models that accurately predict the average size of secondary dendrite arm spacing and the amount of porosity in the low-pressure die cast AISiTMg0.3 alloy.

On “Over-Sized” High-Gain Practical Observers for Nonlinear Systems

引用

IEEE/CAA Journal of Automatica Sinica 2018年第3期5卷 691-698页

作者： daniele Carnevale Corrado Possieri Antonio Tornambè Dipartimento di Ingegneria Civile e Ingegneria Informatica Universita di Roma Tor Vergata

In this paper,it is shown that the performances of a class of high-gain practical observers can be improved by estimating the time derivatives of the output up to an order that is greater than the dimension of the system, which is assumed to be in observability form and, possibly, time-varying. Such an improvement is achieved without increasing the gain of the observers, thus allowing their use in a wide variety of control and identification applications.

Geomechanical design of a room and rib pillar granite mine

引用

Journal of University of Science and Technology Beijing 2008年第2期15卷 97-103页

作者： daniele Peila Claudia Guardini Sebastiano Pelizza Tunnelling Underground Space Center Department of EnvironmentLand and Geotechnology Engineering Politecnico di Torino Tunnelling Underground Space Center Department of EnvironmentLand and Geotechnology EngineeringPolitecnico di TorinoTorinoItaly

The geomechanical and stability design of an underground granite mine located in Canal San Bovo （Trento district, Northeastern Italy） was described. The exploitation of the granite, which is used in the ceramic industry, was carried out by the rooms and rib pillars method. The rooms are 12 m wide while the pillars are 11 m wide and they cross the main discontinuity set of the rock mass in the perpendicular direction. To verify the stability condition of an underground mine, it is necessary to carry out the calcula- tions that are able to check both the local and global stability of the rock mass. In the studied example, this approach has been applied with the development of analytical and numerical parametric analyses and it has permitted to get the best orientation and to design the size of rooms and pillars.

CUBE, a Cable-driven Device for Limb Rehabilitation

Journal of Bionic Engineering 2019年第3期16卷 492-502页

In this paper, a novel cable-driven parallel robot, CUBE, is introduced for the assistance of patients in rehabilitation exercising of both upper and lower limbs. The system is characterized by a lightweight structure that is easy to set-up and operate, for both clinical and home usage for both pre-determined and customized exercises, with control over the position of the end-effector while locking its rotation around the horizontal axes. Its cable-driven design makes it inherently safe in human/robot interactions also due to the extremely low inertia. While a novel end-effector design makes the device wearable both on the upper and lower limbs without having to disassemble any part of the structure. The design is presented with its kinematic analysis. Then, the manufacturing through 3D?printing and commercial components of a first prototype is reported. Finally, the system is validated through motion tests along simple trajectories and two different spatial exercises.
