Secondary users selection and sparse narrow-band interference mitigation in cognitive radio networks
(
Elsevier B.V.
, 2018 , Article)
Spectrum scarcity is a critical problem that may reduce the effectiveness of wireless technologies and services. To address this problem, different spectrum management techniques have been proposed in the literature such ...
Experimental and theoretical studies on axially crushed corrugated metal tubes
(
Elsevier Ltd
, 2018 , Article)
In this paper, crushing behaviors of tube with shallow and deep corrugation are experimentally and theoretically examined under axial loading condition. Three types of specimens were tested under quasi static axial loading. ...
Significance of PCM arrangement in cooling vest for enhancing comfort at varied working periods and climates: Modeling and experimentation
(
Elsevier Ltd
, 2018 , Article)
Personal cooling vests that incorporate phase change material (PCM) have been utilized to improve thermal sensation of people working outdoors in different fields (firefighting, construction, military, police, etc.). In ...
Robustness quantification of hierarchical complex networks under targeted failures
(
Elsevier Ltd
, 2018 , Article)
Robustness is one of the key properties in complex networks to ensure the expected level of performance and service availability in case of perturbations and failures. Network robustness is generally quantified using various ...
Biomechanical design of a composite femoral prosthesis to investigate the effects of stiffness, coating length, and interference press fit
(
Elsevier Ltd
, 2018 , Article)
Traditionally, high stiffness hip prostheses are associated with aseptic loosening. Hence, the effects of stiffness, coating length, and interference press fit on load sharing and micro-movements are investigated for a ...
Effect of microwave sintering on the properties of copper oxide doped Y-TZP ceramics
(
Elsevier Ltd
, 2018 , Article)
The effect of various amounts of copper oxide (CuO) up to 1 wt% on the densification behaviour and mechanical properties of 3 mol% yttria-tetragonal zirconia polycrystal (Y-TZP) were studied by using microwave (MW) sintering ...
