A new chaos-based image-encryption and compression algorithm
( Hindawi Publishing Corporation , 2012 , Article)We propose a new and efficient method to develop secure image-encryption techniques. The new algorithm combines two techniques: encryption and compression. In this technique, a wavelet transform was used to decompose the ... -
A sensitivity analysis approach to identify key environmental performance factors
( Hindawi Publishing Corporation , 2014 , Article)Life cycle assessment (LCA) is widely used in design phase to reduce the product's environmental impacts through the whole product life cycle (PLC) during the last two decades. The traditional LCA is restricted to assessing ... -
Advances in smart materials and applications
( Hindawi Publishing Corporation , 2014 , Article)[No abstract available] -
An Experimental and Kinetic Study of the Sorption of Carbon Dioxide onto Amine-Treated Oil Fly Ash
( Hindawi Publishing Corporation , 2016 , Article)A new CO2 adsorbent is produced from waste oil fly ash (OFA). Ammonium hydroxide solution is used to convert OFA to activated carbon. Then, the product is used for the adsorption of CO2 from a nitrogen/carbon dioxide ... -
Antioxidant Activity Mediates Pirfenidone Antifibrotic Effects in Human Pulmonary Vascular Smooth Muscle Cells Exposed to Sera of Idiopathic Pulmonary Fibrosis Patients.
( Hindawi Publishing Corporation , 2018 , Article)Idiopathic pulmonary fibrosis (IPF) is a chronic lung disease characterized by an exacerbated fibrotic response. Although molecular and cellular determinants involved in the onset and progression of this devastating disease ... -
Approximate analytic solutions of transient nonlinear heat conduction with temperature-dependent thermal diffusivity
( Hindawi Publishing Corporation , 2014 , Article)A new approach for generating approximate analytic solutions of transient nonlinear heat conduction problems is presented. It is based on an effective combination of Lie symmetry method, homotopy perturbation method, finite ... -
Automatic prediction of age, gender, and nationality in offline handwriting
( Hindawi Publishing Corporation , 2014 , Article)The classification of handwriting into different categories, such as age, gender, and nationality, has several applications. In forensics, handwriting classification helps investigators focus on a certain category of ... -
An Autonomous Packet Transmission Strategy for Opportunistic Wireless Sensor Networks
( Hindawi Publishing Corporation , 2012 , Article)We consider a wireless sensor network that comprises a single hop between the sensor nodes and the central controller node with multiple antennas. In this system model, we concentrate on the single-beam opportunistic ... -
Comparative Serological Study for the Prevalence of Anti-MERS Coronavirus Antibodies in High- and Low-Risk Groups in Qatar
( Hindawi Publishing Corporation , 2019 , Article)Infection with Middle East respiratory syndrome coronavirus (MERS-CoV) could be asymptomatic or cause mild influenza-like illness. Therefore, the prevalence of MERS-CoV infections in the general population could be ... -
Comparison of the Protective Effects of Individual Components of Particulated trans-Sialidase (PTCTS), PTC and TS, against High Cholesterol Diet-Induced Atherosclerosis in Rabbits
( Hindawi Publishing Corporation , 2017 , Article)Previous studies showed the presence of Mycoplasma pneumoniae (M. pneumoniae) and membrane-shed microparticles (MPs) in vulnerable atherosclerotic plaques. H&S Science and Biotechnology developed PTCTS, composed by natural ... -
Considering the Specific Impact of Harsh Conditions and Oil Weathering on Diversity, Adaptation, and Activity of Hydrocarbon-Degrading Bacteria in Strategies of Bioremediation of Harsh Oily-Polluted Soils
( Hindawi Publishing Corporation , 2017 , Article)Weathering processes change properties and composition of spilled oil, representing the main reason of failure of bioaugmentation strategies. Our purpose was to investigate the metabolic adaptation of hydrocarbon-degrading ... -
Constraint violations in stochastically generated data: Detection and correction strategies
( Hindawi Publishing Corporation , 2014 , Article)We consider the generation of stochastic data under constraints where the constraints can be expressed in terms of different parameter sets. Obviously, the constraints and the generated data must remain the same over each ... -
Continuous-Time ΣΔ ADC with Implicit Variable Gain Amplifier for CMOS Image Sensor
( Hindawi Publishing Corporation , 2014 , Article)This paper presents a column-parallel continuous-time sigma delta (CTSD) ADC for mega-pixel resolution CMOS image sensor (CIS). The sigma delta modulator is implemented with a 2nd order resistor/capacitor-based loop filter. ... -
Control of Power Converters for Emerging Applications of Power Electronics
( Hindawi Publishing Corporation , 2016 , Article)With the skyrocketed development in semiconductor devices, power electronics converters, either at system-level or at device-level, are receiving special attention in different applications as renewable energy sources, ... -
Coupled coincidence point results for (ψ,φ) -weakly contractive mappings in partially ordered Gb-metric spaces
( Hindawi Publishing Corporation , 2013 , Article)In this paper we present some coupled coincidence point results for (ψ,φ) -weakly contractive mappings in the setup of partially ordered Gb -metric spaces. Our results extend the results of Cho et al. (Fixed Point Theory ... -
Cross-Layer Optimal Rate Allocation for Heterogeneous Wireless Multicast
( Hindawi Publishing Corporation , 2009 , Article)Heterogeneous multicast is an efficient communication scheme especially for multimedia applications running over multihop networks. The term heterogeneous refers to the phenomenon when multicast receivers in the same session ... -
Evaluation of Global Genomic DNA Methylation in Human Whole Blood by Capillary Electrophoresis UV Detection
( Hindawi Publishing Corporation , 2017 , Article)Alterations in global DNA methylation are implicated in various pathophysiological processes. The development of simple and quick, yet robust, methods to assess DNA methylation is required to facilitate its measurement and ... -
Fixed point results for generalized chatterjea type contractive conditions in partially ordered G-metric spaces
( Hindawi Publishing Corporation , 2014 , Article)In the framework of ordered G -metric spaces, fixed points of maps that satisfy the generalized Chatterjea type contractive conditions are obtained. The results presented in the paper generalize and extend several well ... -
