    Abstract: After the study on the confines of the commercial incandescent lamps, we have a conclusion that the both of the W-filament lamps and LED lamps already have the optimized as the power hungry incandescent lamps. Only FL lamps have a capability for the significant improvement in the consumed energy and quantum efficiency. We have studied the FL lamps ... Show More
  • Low Level Carbon Detection in Steel Alloys Based on Optimization of Observation Conditions of Laser-Induced Breakdown Spectroscopy (LIBS) in Ambient Air

    DOI: 10.11648/j.wjap.20160101.12
    Abstract: In this study, we present results regarding the application of a relatively simple bench-top laser-induced breakdown spectroscopic (LIBS) technique working in the UV/visible spectral region for the rapid, direct and sensitive quantification of the element carbon in steel alloys under ambient air standard conditions. We carry out further optimizatio... Show More
  • Anisotropic Stars with a Prescribed Form of Metric Potential Z

    Manuel Malaver

    Issue: Volume 1, Issue 1, August 2016
    Pages: 20-25

    Accepted: 8 August 2016
    Published: 31 August 2016
    DOI: 10.11648/j.wjap.20160101.13
    Abstract: Assuming a linear equation of state and charged anisotropic matter, in this paper we obtain two new classes of exact solutions of the Einstein-Maxwell system with a particular form of the metric potential Z deduced for Malaver (2016). A physical analysis of electromagnetic field indicates that is regular in the origin and well behaved. The obtained... Show More
  • First-Principles Local Density Plus Virtual Crystal Approximations Study of HgCdTe

    Wei Zeng, Qi-Jun Liu, Zheng-Tang Liu

    Published: 10 November 2016
    DOI: 10.11648/j.wjap.20160101.14
    Abstract: We have calculated the structural, elastic, mechanical and electronic properties of cubic Hg0.5Cd0.5Te by using the first-principles density functional theory (DFT) within the local density approximation (LDA) plus virtual crystal approximation (VCA). Compared with the previous experimental and theoretical data of cubic Hg0.5Cd0.5Te, our calculated... Show More
