Influence Analysis of Washers Material in the Fatigue Life of Bolted Joints
(2015-09-22)
The union of parts by using bolts is one of the most used, which combines versatility and low cost, and the failure of a single bolt can cause failure of the entire structure or machine. Several factors influence the ...
Stability of BEC Systems in Nonlinear Optical Lattices
(Springer, 2011-01-01)
The dynamics and stability of a Bose-Einstein Condensate, described by a two-dimensional nonlinear Schrodinger equation in a one-dimensional conservative plus dissipative nonlinear optical lattice, are investigated. In the ...
Multi-layers lateral SOI PIN photodiodes for solar cells applications
(2019-08-01)
In this paper, a lateral PIN photodiode based on a SOI wafer has been studied through numerical simulations. This device can be used as a solar cell embedded in a CMOS circuit in order to propose autonomous ultralow-power ...
A negative-bias-temperature-instability study on omega-gate silicon nanowire SOI pMOSFETs
(2019-08-01)
The Negative-Bias-Temperature-Instability (NBTI) is an important reliability parameter for advanced technology nodes. This work presents an experimental study of NBTI in omega-gate nanowire (NW) pMOSFET. The 3D-numerical ...
Importance of event detection and nonlinear characterization of dynamical systems with discontinuity boundary
(2021-01-01)
In this study, the response of a dynamical system with an increasingly stiff freeplay nonlinearity is investigated. Numerical simulations are carried out on a forced Duffing oscillator with low, intermediate, and hard ...
Natural Quasi-Rendezvous and Evasive Maneuvers assisted by Atmospheric Drag
(2019-11-04)
The study of evasive maneuvers of spacecraft in the face of the danger of collision with space debris is essential and important today due to the growth of missions at low altitudes (LEO). Bodies that orbit this region are ...
Adaptive Secure Rate Allocation via TAS/MRC under Multi-Antenna Eavesdroppers
(Ieee, 2019-01-01)
This paper investigates the secrecy outage performance of a multiple-input multiple-output and multi-antenna eavesdropper system. We consider a novel formulation for the secrecy outage probability, which is capable of ...
Reactivation of natural fractures network by hydraulic fracturing
(2020-11-18)
Modelling the process of induced fracture initiation, propagation and interaction with natural fractures is a very challenged task. Significant progress has been made in recent years in the development of complex fracture ...
A New Approach to Compute Grounding Impedance of Rods in a Frequency Dependent Multi-layer Soil
(Ieee, 2020-01-01)
Long cylindrical rods are commonly employed to grounding system in transmission lines and they can be buried in stratified soils. In this condition, the grounding impedance is significantly modified by the presence of ...
Modeling the formation and propagation of desiccation cracks in soils
(2014-01-01)
The problem of desiccation cracks in soils has received increasing attention in the last few years, in both experimental investigations and modeling. Experimental research has been mainly focused on the behavior of slurries ...
