Conceptual design of a fully passive transfemoral prosthesis to facilitate energy-efficient gait
(IEEE, 2018-12)
In this paper, we present the working principle and conceptual design toward the realization of a fully-passive transfemoral prosthesis that mimics the energetics of the natural human gait. The fundamental property of the ...
Challenges for radiative transfer 1: towards the effective solution of conjugate heat transfer problems
(Elsevier, 2018-12)
This paper lists crucial challenges in radiative transfer with the objective of gathering information on improving and choosing methods for solving conjugate heat transfer problems. Developments in computational and ...
Effect of electrostatic stabilization on thermal radiation transfer in nanosuspensions: Photo-thermal energy conversion applications
(Elsevier, 2018-04)
Solar thermal collectors are among the most important photo-thermal energy conversion systems. Effectiveness of these systems is measured by the ability of working fluid to absorb incident radiative energy. Although ...
Adaptive MIMO FSO communication systems with spatial mode switching
(IEEE, 2018-08)
In this paper, we propose an adaptive multiple-input multiple-output (MIMO) free-space optical (FSO) system with dynamic adaptation between spatial modes of operation. The proposed adaptive system supports three MIMO modes. ...
Rounding heuristics for multiple product dynamic lot-sizing in the presence of queueing behavior
(Elsevier, 2018-12)
We present heuristics for solving a difficult nonlinear integer programming (NIP) model arising from a multi-item single machine dynamic lot-sizing problem. The heuristic obtains a local optimum for the continuous relaxation ...
Increasing test efficiency by risk-driven model-based testing
(Elsevier, 2018-10)
We introduce an approach and a tool, RIMA, for adapting test models used for model-based testing to augment information regarding failure risk. We represent test models in the form of Markov chains. These models comprise ...
Energy optimized routing with directional antennas and tagging for multimedia sensor networks
(IEEE, 2018-04-24)
Several routing optimization strategies have been proposed in research for Wireless Multimedia Sensor Network (WMSN), because of unavailability of the external power source. In this paper, a global energy optimization ...
Eigenvalues and dynamical properties of weighted backward shifts on the space of real analytic functions
(Institute of Mathematics Polish Academy of Sciences, 2018)
Usually backward shift is neither chaotic nor hypercyclic. We will show that on the space A(Omega) of real analytic functions on a connected set Omega subset of R with 0 is an element of Omega, the backward shift operator ...
Dual resonance proximity coupled patch antenna
(IEEE, 2018-05-24)
In this paper there are four different shape of proximity patch antennas (straight, trimmed, trapezoid and ribbon). The minimum input match achieved with the straight proximity patch antenna as -39.68 dB. The maximum gain ...
A software defined radio based data link design for VHF band wireless sensor networks
(Elsevier, 2018-10)
In this paper, we present an overall data link design for a tactical wireless sensor network operating at VHF band considering software defined radio (SDR) approach. An empirical channel modeling for the target environment ...
