High temperature thermal stability of innovative nanostructured thin coatings for advanced tooling
(
Trans Tech Publications Ltd
, 2014 , Article)
Tools for machining are made of hard steels and cemented carbide (WC-Co). For specialized applications, such as aluminium machining, diamond or polycrystalline cubic boron nitride are also used. The main problem with steel, ...
Synthesis, immunomodulation and cytotoxic effects of vanadium (IV) complexes
(
Bentham Science Publishers B.V.
, 2014 , Article)
Vanadium is known to exhibit several bioactivities and shows potential as a pharmaceutical drug. The current studies were conducted with the goal of synthesizing a new generation of oxovanadium(IV) complexes, investigating ...
Effect of temperature and erosion on pitting corrosion of X100 steel in aqueous silica slurries containing bicarbonate and chloride content
(
Elsevier Ltd
, 2014 , Article)
The effect of temperature on erosion-enhance pitting corrosion behavior of X100 steel has been investigated. Tests were performed at two temperatures with the help of open circuit potential (OCP), potentiodynamic polarization ...
Comparability of Interview and Self-Administration of the Functional Assessment of Chronic Illness Therapy-Tuberculosis (Facit-Tb) Instrument in Iraqi Pulmonary Tuberculosis Patients
(
Elsevier
, 2014 , Article)
Objectives
To investigate the extent to which two different modes of administration (interview by a trained interviewer versus self-administration) yielded a comparable estimate of health-related quality of life (HRQL) ...
Automated detection of perinatal hypoxia using time-frequency-based heart rate variability features
(
Springer Berlin Heidelberg
, 2014 , Article)
Perinatal hypoxia is a cause of cerebral injury in foetuses and neonates. Detection of foetal hypoxia during labour based on the pattern recognition of heart rate signals suffers from high observer variability and low ...
Criticality measures for components with multi-dimensional degradation
(
Taylor and Francis Ltd.
, 2014 , Article)
Failures of engineering structures and equipment are often attributed to the failure of a single component. Hence, it is important to identify critical components in a system and understand how a component's criticality ...
Design of power system stabilizers based on μ-controller for power system stability enhancement
(
Elsevier
, 2014 , Article)
Abstract The problem of the poorly damped low-frequency (0.1–0.4Hz) oscillations of power systems has been a matter of concern to power engineers for a long time, because they limit the power transfer capability in power ...
Exact average OFDM subcarrier SINR analysis under joint transmit-receive I/Q imbalance
(
IEEE
, 2014 , Article)
The subcarrier signal-to-interference-plus-noise ratio (SINR) expression for orthogonal frequency-division multiplexing (OFDM) systems impaired by in-phase/quadrature (I/Q) imbalance is a ratio of correlated random variables. ...
Hybrid radio resource allocation and interference coordination for type 1a-relayed long term evolution uplink
(
Institution of Engineering and Technology
, 2014 , Article)
Relay technology has been included in long term evolution (LTE) cellular system through 3GPP Release 10. Relay-based LTE cellular system is one of the most promising technologies to enhance the throughput and coverage of ...
A series flywheel architecture for power levelling and mitigation of DC voltage transients in multi-terminal HVDC grids
(
Institution of Engineering and Technology
, 2014 , Article)
This study proposes a new architecture of flywheel energy storage system (FESS) which can be implemented at generating unit (GU) level (e.g. wind turbine) or scaled up for application in grid-side converter (GSC) stations ...
