Research ArticleOpen accessIn the abstractBlind Source Separation under Semi-White Gaussian Noise and Uniform Noise: Performance Analysis of ICA, Sobi and JadeRMuna H. Fatnan, Zahir M. Hussain, Hind R. MohammedA comparative study is presented to evaluate the performance of three important Blind Source Separation (BSS) techniques under noisy conditions. The ability of FastICA, SOBI and JadeR is tested in separating several kinds of signals under noisy conditions, including human speech and frequency-modulated (quadratic and linear FM) signals. Additionally, different mixing matrices are used to inspect the effect of the … …Journal of Computer Science, Vol. 15, Issue 1 · 31 Dec 2018 · 7,991 accessesView PDFCite
Review ArticleOpen accessIn the abstractEnvironmental Concerns and Toxicogenetic Endpoints of Priority Substances (PSs) and Contaminants of Emerging Concerns (CECs): A Comprehensive ReviewDe-Sheng Pei, Chun-Di Chen, Naima Hamid et al.Priority Substance (PSs) and Contaminant of Emerging Concerns (CECs) exhibited a wide range of environmental and public health concerns worldwide. This review summarized the documented studies related to the current surface water occurrence, spatial distribution, ecological risks and toxicity of selected PSs, such as polycyclic aromatic hydrocarbons (PAHs) and CECs, such as Di(2-Ethylhexyl) Phthalate (DEHP) and Pharmaceuticals and Personal Care … …American Journal of Environmental Sciences, Vol. 14, Issue 3 · 10 Jul 2018 · 8,393 accessesView PDFCite
Research ArticleOpen accessIn the abstractImprovements on Semi Critical Assisted-Solvent Extraction of Biocrude Oil from Spirogyra. sp Macro AlgaeTulio Chavez-Gil, Hany F. Sobhi, Alexis Pacheco-LaracuenteHere, we report on an improved chemical method to extract hydrocarbons (CH) and Fatty Acid Methyl Esters (FAME) from wild green macro algae, which is higher than that carried out with conventional Soxhlet (Sx) and similar to that of Subcritical (SbC) or supercritical fluid (SCE) extraction methods. Crude oil plus residual biomass gave combined calorific values of 49.05 MJ/kg in … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 18 Apr 2018 · 10,085 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Ecological Factors on Snails Infection by Schistosoma japonicum in Central Sulawesi, IndonesiaSutrisnawati Mardin, Teguh Wahju Sardjono, Loeki Enggar Fitri et al.In Central Sulawesi, Napu valley and Lindu Lake (Indonesia), Schistosoma are spread in the host snails (Oncomelania hupensis lindoensis). In the present work, the influence of ecological factors on the spreading of Schistosoma japonicum cercariae infection in the snails were analyzed. The Oncomelania hupensis lindoensis snails were collected and analyzed by ring method in the form of graphs and matrices. … …American Journal of Environmental Sciences, Vol. 14, Issue 2 · 5 Apr 2018 · 8,495 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeometry and Direct Kinematics to MP3R with 4×4 OperatorsRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.Anthropomorphic mechatronic systems are the most widely used robotics systems worldwide today in industry and in all automated environments. These systems are best suited to the modern automation and mechatronisation needs of the modern world, being mobile, dynamic, light, robust, complex, technologically simple, easy to design and manufactured, implemented, maintained and used in almost any industrial site, both in machine … …Journal of Mechatronics and Robotics, Vol. 1, Issue 2 · 1 Dec 2017 · 7,241 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comprehensive Review and Performance Evaluation of Detection Techniques of Black Hole Attack in MANETNaveen Hemrajani, Sunil Kumar JangirMobile Ad Hoc Network (MANET) is an auto Configuring network. Due to its natural characteristics, a MANET is vulnerable to many security threats. Blackhole attack compromises the performance and the reliability of the network. Since nodes are allowed to move freely within the network, it becomes very important to protect the communication among mobile nodes for the sake of security. … …Journal of Computer Science, Vol. 13, Issue 10 · 18 Oct 2017 · 7,737 accessesView PDFCite
Review ArticleOpen accessIn the abstractSolid State Hydrogen Storage in Polymeric Materials: A ReviewRolando PediciniHydrogen storage is one of the major obstacles to overcoming so that hydrogen becomes next fuel and/or energy carrier of the future. The hydrogen storage materials are one of the principal challenges that must be met before the development of a hydrogen economy. Among all materials studied an important class that could have a future, in particular in portable applications, … …Energy Research Journal, Vol. 8, Issue 2 · 7 Aug 2017 · 7,082 accessesView PDFCite
Research ArticleOpen accessIn the abstractAccessing the Appropriateness of a Spatial Regression Using Generalized (h1h2-)Slepian Random FieldWayan Somayasa, Jamhir Safani, La Ode Ngkoimani, Muhamad Zamrun F.In this study we derived asymptotic goodness-of-fit test (model check) for spatial regression where the critical region as well as the p-value of the tests are approximated based on the distribution of a type of the integral functional of the generalized (h1h2-)-Slepian field and the set-indexed Gaussian white noise. Such random fields are obtained as the limit process of the … …Journal of Mathematics and Statistics, Vol. 13, Issue 2 · 2 May 2017 · 7,364 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiodegradation of BTEX: Optimization through Response Surface MethodologyAyat E. El Telib, Muftah H. El-Naas, Janice A. AcioResponse Surface Methodology (RSM) was used to optimize the biodegradation of Benzene, Toluene, Ethyl benzene and m-, o-, p-Xylene (BTEX) by Pseudomonas putida immobilized in PVA matrices in a specially-designed novel Spouted Bed Bioreactor System (SBBS). A mixture of 60 mg L-1 of BTEX compounds in air was contacted with the immobilized bacteria in three spouted bed bioreactors in series. … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 3 Jan 2017 · 8,285 accessesView PDFCite
Review ArticleOpen accessIn the abstractCoenzyme Q10 and its Effective SourcesHamideh Vaghari, Roholah Vaghari, Hoda Jafarizadeh-Malmiri, Aydin BerenjianCoenzyme Q10 (2,3-dimethoxy, 5-methyl, 6-decaprenyl benzoquinone, CoQ10) is naturally present in many organisms. It has key roles in several biochemical pathways. CoQ10, as an electron and proton carrier for energy coupling leads to Adenosine Triphosphate (ATP) formation. Furthermore, in medicine, the pharmacological use of CoQ10 has attracted more attention due to its benefits in treating cardiovascular and degenerative neurologic diseases. … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 4 · 10 Oct 2016 · 9,283 accessesView PDFCite
