Finite time convergence based on robust synergetic control (SC) theory and terminal attractor techniques is investigated. To this end a fast terminal synergetic control law (FTSC) is applied to drive a DC–DC Buck converter via simulation and through a dSpace based experimental setup to validate the approach. As robust as [...]

A novel low-cost broadband photodetector was fabricated based on nanostructures SnS thin film with cubic crystal structure. The SnS thin film was prepared by means of chemical bath deposition. The photodetector demonstrated a high performance for abroad range light detection from UV to near-infrared. The photoresponse characteristics were tested under [...]

This chapter discusses the mechanism of photocatalysis processes using nanomaterials and their applications. It also focuses on the different types of nanomaterials used in photocatalysis in terms of their synthesis method, microstructure, and their optical and magnetic properties. A number of photocatalytic materials are synthesized by employing hydrothermal methods, such [...]

Nanotechnology is often described as an emerging technology – one that not only holds promise for society but also is capable of revolutionizing our approaches to common problems. It is an emerging technological field with great potential to lead in breakthroughs that can be applied in real life. Novel nano-/biomaterials [...]

The objective of this paper is to analyze temporal and seasonal trends of air pollution in Bahrain between 2006 and 2012 by utilizing datasets from five air quality monitoring stations. The non-parametric and robust Theil-Sen approach is employed to study quantitatively temporal variations of particulate matter (PM10 and PM2.5), nitrogen [...]

The aim of this study is to investigate in-depth the effect of Co2+ ions doping on ZnFe2O4 nanoparticles in term of morphology, magnetic and optical properties. Zn1-xCoxFe2O4 (x = 0.0, 0.1, 0.2, 0.3, 0.4, 0.5) powders were prepared by co-precipitation method. X-ray diffraction (XRD) and Energy Dispersive Spectroscopy (EDS) confirmed [...]

Many universities are striving to have an environmental impact on the society as they are considered as small communities aiming to be eco-friendly and having low CO2 emission. This concept has been emerging after the worldwide concern on the ozone depletion issue and global warming. As a result, many titles [...]

This paper proposes a linear feedback structure of sliding mode control for a three-phase rectifier fed by a non-ideal supply voltage. The aim of the proposed technique is to achieve power flow with unity power factor even under distorted and/or unbalanced grid voltage condition. The performance of the proposed sliding [...]

The effects of various CO2 concentrations in CO2 bioconversion by cultivation of microalga Chlorella vulgaris were investigated using a vertical tubular photobioreactor. The response surface technique with central composite design was applied to model the CO2 biofixation rate, the specific growth rate (SGR), and the biomass productivity of C. vulgaris [...]

Abstract Tungsten oxide (WO3) nanoparticles doped with different amounts of manganese ions (W1−xMnxO3, where x = 0.011, 0.022 and 0.044) were synthesised by hydraulic acid-assisted precipitation, followed by thermal calcinations. The powders were characterised by X-ray fluorescence (XRF), X-ray diffraction (XRD), diffuse reflectance spectroscopy (DRS) and magnetic measurements. The monoclinic [...]
