TL;DR: In this article, refractory high entropy alloys with the compositions of NbTiVTaAlx were prepared under a high-purity argon atmosphere and their microstructure and compressive properties at room temperature were investigated.

TL;DR: The Markowitz mean-variance optimization algorithm is developed to solve the asset allocation problem and the Black Litterman model is enhanced by including the error estimates resulting from the bootstrapping methods.

TL;DR: In this paper, the newly engineered metal matrix composite (MMC) of aluminium 7075 reinforced with 10 wt% of B4C particles were prepared by stir casting method and experiments were carried out by adopting face centered central composite design of response surface methodology.

TL;DR: A new priority based job scheduling algorithm (PJSC) in cloud computing is proposed based on multiple criteria decision making model that will help in job scheduling of cloud computing.

TL;DR: This paper proposes to use a hybrid intelligent approach using combination of classifiers in order to make the decision intelligently, so that the overall performance of the resultant model is enhanced.

TL;DR: In this paper, the current status of biofuel from algae as a renewable source is reviewed and the advantages of biofuels from microalgae can be discussed, such as their rapid growth rate, greenhouse gas fixation ability and high production capacity of lipids.

TL;DR: The performance analysis of the protocols is carried out on Adhoc On-demand Distance Vector, Dynamic Source Routing, Optimized Link State Routing and Destination Sequenced Distance Vector protocols using NS2 simulator.

TL;DR: In this paper, the authors exploit the multi-spectral optical data from the LANDSAT ETM + (Enhanced Thematic Mapper) to map surface states, including indices of salinity and sodicity as: (BI: Brightness Index), NDSI: Normalized Difference Salinity Index, SI: Salinity index, ASI: Aster Salinityindex (Agriculture), Index of Salinity (using GIS Geographic Information System and remote sensing), and finally the SSSI “Soil Salinity and Sodicity Index”.

TL;DR: Water scarcity is a manmade phenomenon brought about by the increasing demands of the population for water, which has an adverse impact on domestic hygiene, public health, and cost of domestic water, and could impart political problems as serious as bringing down governments as mentioned in this paper.

TL;DR: It has been demonstrated that the proposed novel feature selection approach for the classification of high dimensional cancer microarray data using Particle swarm Optimization gives better result than others.

TL;DR: In this article, the authors examined the performance of supercritical carbon dioxide extraction of lipids from Botryococcus braunii for biodiesel production and found that the optimum operating conditions for a supercritical extraction were pressure between 220-250 bar and temperature of 50°C.

TL;DR: In this article, a large-scale integrated water reuse process based on MBR+RO technology (capacity 200 m3/d) has been designed and established in a German laundry within an EC funded project eventually resulting in a reuse ratio of around 80% of the total wastewater.

TL;DR: A review of metal matrix composite reinforced with TiB2 particles developed after 1997 is presented in this article, where the main focus is given to Aluminium as matrix material because of its unique combination of good corrosion resistance, low electrical resistance and it possesses excellent mechanical properties in addition to good corrosion resist due to which the alloy finds extensive application in naval vessels manufacturing.
