Harmonious industrialization: classifying, connecting and valuating industries based on their contribution to human need
(IEOM, 2017)An industry can be defined as a system within which homogenous processes strive toward a common generalizable outp ut. An industry comprises various economic, social and environmental activities. Various ... -
Harvesting of Hartbeespoort Dam micro–algal biomass through sand filtration and solar drying
(ELSEVIER, 2013)Renewable energy sources such as biomass are becoming more and more important as alternative to fossil fuels. One of the most exciting new sources of biomass is microalgae. One of the major obstacles in the commercial production ... -
Hazardous elements in agricultural soils surrounding a coal plant from Santa Catarina (Brazil)
(Swanson School of Engineering, Univ of Pittsburgh, 2015) -
Heading alignment with summarized inertial pose constraints
(IEEE, 2014)A discontinuity seems to exist in present aided inertial navigation systems – the operational availability of high cost inertial navigation currently depends on the availability of a valid GPS lock. In general GPS ... -
Heuristic approach to the passive optical network with fibre duct sharing planning problem
(ORSSA, 2015)Similar to the constrained facility location problem, the passive optical network (PON) planning problem necessitates the search for a subset of deployed facilities (splitters) and their allocated demand points (optical ... -
High-glycolytic cancers and their interplay with the body's glucose demand and supply cycle
(Elsevier, 2011)Many difficult-to-treat solid cancer tumours and metastases have high-glucose uptake, usually under hypoxic conditions. Hypoxic tumours suppress the immune system and are insensitive to traditional chemoradiotherapies. The ... -
High-temperature thermal plasma treatment of monazite followed by aqueous digestion
(SAIMM, 2016)Monazite is a chemically inert, radioactive phosphate mineral that contains the light rare earth metals (Ce, La, Nd, Pr and Y), thorium and uranium. A new process, which improves the extraction efficiency of monazite, ... -
How do high glycemic load diets influence coronary heart disease?
(BioMed Central, 2015)Background: Diet has a significant relationship with the risk of coronary heart disease (CHD). Traditionally the effect of diet on CHD was measured with the biomarker for low-density lipoprotein (LDL) cholesterol. However, ... -
Hybrid nuclear plant simulator design requirements to enable dynamic diagnostics of plant operations
(Elsevier, 2017)With nuclear plant full scope simulator technology reaching maturity, the possibility of using its capabilities in expert systems such as online plant diagnostics has become a reality. The effectiveness of plant diagnostics ... -
Hydrocyclone cut-size estimation using artificial neural networks
(Elsevier, 2016)The hydrocyclone is widely used throughout the mineral processing industry when working with slurries. It is either used for classifying, desliming or dewatering. Hydrocyclones are inexpensive, application-efficient and ... -
Hydrogel-based bioflocculants for the removal of organic pollutants from biodiesel wastewater
(Springer, 2017)Hydrogel based bioflocculants namely Gelatin and acrylic acid-co-acrylamide [GL-cl-P(AA-co-AAM)] and hybrid hydrogel composite with good adsorption potential, were synthesized in this study for the treatment of biodiesel ... -
Hydrogen generation by means of hydrolysis using activated Al-In-Bi-Sn composites for electrochemical energy applications
(ESG, 2017)Effective activation compounds are developed to produce hydrogen via hydrolysis of ball-milled Al-In-Bi-Sn composites in tap water at room temperature. Al-In-Bi-Sn composites are successfully activated by 3 h of milling. ... -
Hydrogen generation of mechanochemically activated Al-Bi-In composites
(Elsevier, 2017)The individual and combined effects of Bi and In on the morphology change and reactivity towards hydrogen release of Al during mechanochemical preparation of binary and ternary Al composites were determined. Subsequently, ... -
Hydrogen production from ammonia decomposition over a commercial Ru/Al2O3 catalyst in a microchannel reactor: experimental validation and CFD simulation
(Elsevier, 2016)In this work, an integrated experimental and CFD modelling technique was used to evaluate a microchannel reactor producing hydrogen from ammonia decomposition using a commercial Ru/Al2O3 catalyst. The microchannel reactor ... -
HySA infrastructure center of competence: a strategic collaboration platform for renewable hydrogen production and storage for fuel cell telecom applications
(IEEE, 2014)The Department of Science and Technology of South Africa developed the National Hydrogen and Fuel Cells Technologies (HFCT) Research, Development and Innovation Strategy. The National Strategy was branded Hydrogen South ... -
Identification of reaction zones in a commercial Sasol-Lurgi fixed bed dry bottom gasifier operating on North Dakota lignite
(Elsevier Science, 2011)The Sasol-Lurgi fixed bed dry bottom gasification technology has the biggest market share in the world with 101 gasifiers in operation. To be able to further improve the technology and also to optimise the operating plants, ... -

Identifying opportunities for deterministic network coding in wireless mesh networks
(SAIEE Publishers, 2011)Recent advances in methods to improve network utilisation has lead to the introduction of Network Coding, a technique that can reduce local congestion in a network by combining information sent over the network. In this ... -
The IGY and beyond: a brief history of ground-based cosmic-ray detectors
(Elsevier, 2009)The state of art of ground-based cosmic-ray research from its discovery to present is reviewed. After discovery of cosmic rays by Hess in 1912, the nature of the primary and secondary radiation was established from recordings ... -
