Thermal and mechanical characterization of injection moulded high density polyethylene/paraffin wax blends as phase change materials
(
Elsevier Ltd
, 2014 , Article)
Thermal and mechanical properties of blends based on high density polyethylene and paraffin wax were investigated. The blends were prepared from 5 to 50vol. % of paraffin wax employing a twin-screw extruder. Thermal behaviour ...
Processing, characterization and modeling of recycled polypropylene/glass fibre/wood flour composites
(
Elsevier Ltd
, 2014 , Article)
Polypropylene (PP) is one of the most common thermoplastic materials in the world. There is a need to recycle the large amount of this used material. To overcome the environmental problems, related to the polymer waste, ...
Controlling the trajectory of a flexible ultrathin endoscope for fully automated bladder surveillance
(
IEEE
, 2014 , Article)
During cystoscopy, the urologist manually steers a cyst scope inside a patient's bladder to visually inspect the inner surface. Cystoscopies are performed as part of surveillance for bladder cancer, making it the most ...
Improved mechanical properties of recycled linear low-density polyethylene composites filled with date palm wood powder
(
Elsevier, Ltd
, 2014 , Article)
Recycled linear low-density polyethylene (RLLDPE) was blended with date palm wood powder to prepare composites in which the concentration of the filler ranged from 10 to 70wt.%. The cross-linking of composites was performed ...
A preemptive bound for the Resource Constrained Project Scheduling Problem
(
Springer US
, 2014 , Article)
The Resource Constrained Project Scheduling Problem is one of the most intensively investigated scheduling problems. It requires scheduling a set of interrelated activities, while considering precedence relationships, and ...
Financial portfolio management through the goal programming model: Current state-of-the-art
(
Elsevier B.V.
, 2014 , Article)
Since Markowitz (1952) formulated the portfolio selection problem, many researchers have developed models aggregating simultaneously several conflicting attributes such as: the return on investment, risk and liquidity. The ...
A review of time-frequency matched filter design with application to seizure detection in multichannel newborn EEG
(
Elsevier Inc.
, 2014 , Article)
This paper presents a novel design of a time-frequency (t-f) matched filter as a solution to the problem of detecting a non-stationary signal in the presence of additive noise, for application to the detection of newborn ...
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 ...
Outage performance of cooperative systems under IQ imbalance
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
In this contribution, we investigate the outage performance of OFDM-based Decode and Forward (DF), Amplify and Forward (AF) and Controlled DF (CDF) cooperative systems under IQ Imbalance (IQI). In particular, tractable and ...
Synthesis, immunomodulation and cytotoxic effects of vanadium (IV) complexes
(
