Research ArticleOpen accessIn the abstractDetermination of Absorption Coefficients and Thermal Diffusivity of Modulated Doped GaAlAs/GaAs Heterostructure by Photothermal Deflection SpectroscopyS. Aloulou, M. Fathallah, M. Oueslati, A. SfaxiWe report in this study theoretical and experimental studies of photothermal deflection spectroscopy (PDS) for planar doped heterostructures AlGaAs/GaAs. The PDS spectra at T=300K are recorded by varying the wavelength of the excited radiation for different modulation frequencies. They show two different regions related to the fundamental electronic transitions from GaAs and Si doped AlGaAs. The DX levels have been … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,262 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCadmium Stress Responses in Medicinal and Oilseed Plants: Safflower as a Promising Candidate for Soil Cadmium RemediationChristos Kikis, Giorgos Thalassinos, Vasileios AntoniadisThis study investigated the growth responses of five economically important plants—chamomile (Matricaria recutita), oregano (Origanum vulgare), safflower (Carthamus tinctorius), sage (Salvia officinalis), and wormwood (Artemisia absinthium) exposed to increasing Cd levels. Over 60 days, plants were subjected to Cd concentrations of 0, 1, 2, 3, and 4 mg per pot. Growth parameters and Cd accumulation were then assessed. At the … …American Journal of Agricultural and Biological Sciences, Vol. 20, Issue 1 · 13 Nov 2025 · 3,410 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOn the Influence of Stator Slot shape on the Energy Conservation Associated with the Submersible Induction MotorsM. Sundaram, P. NavaneethanProblem statement: A good design of Submersible Induction Motor is required to maintain maximum efficiency level. This can be achieved in one way by optimum design of magnetic circuit. The magnetic circuit of an Induction Motor is formed by the combination of Stator core, Rotor core and air gap. In applications like Submersible Motor Pumps, the air gap cannot be … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,710 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordIAFIR Optimization against NOMA Competitors: A Comprehensive Analysis on Energy-Efficient Non-Orthogonal Multiple AccessS. Pavithra, S. ChitraThe ever-growing demands of next-generation wireless networks necessitate the exploration of innovative technologies to enhance spectral efficiency, user experience and network performance. Non-Orthogonal Multiple Access (NOMA) has emerged as a promising candidate, offering the potential for increased capacity and improved system reliability. NOMA allows multiple users to share the same time-frequency resource, breaking away from traditional orthogonal access methods. In … …Journal of Computer Science, Vol. 20, Issue 8 · 31 May 2024 · 5,053 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordTheoretical Investigation of Two Antiemetic Drugs at DFT LevelKhalil Errahmane Kanouni, Yacine BenguerbaThe geometries and the bonding properties have been predicted for two antiemetic drugs using Density Functional Theory method (DFT). Mulliken population and frontier molecular orbital analysis with the determination of the physicochemical properties was performed using the Amsterdam Density Functional package (ADF). To calculate the exchange-correlation energy, the Generalized Gradient Approximation of Becke-Perdew (GGA-BP) was used. The most important finding … …Current Research in Bioinformatics, Vol. 9, Issue 1 · 14 May 2020 · 11,496 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordGray-Level Co-occurrence Matrix Bone Fracture DetectionHum Yan Chai, Lai Khin Wee, Tan Tian Swee et al.Problem statement: Currently doctors in orthopedic wards inspect the bone x-ray images according to their experience and knowledge in bone fracture analysis. Manual examination of x-rays has multitude drawbacks. The process is time-consuming and subjective. Approach: Since detection of fractures is an important orthopedics and radiologic problem and therefore a Computer Aided Detection(CAD) system should be developed to improve the … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 8,968 accessesView PDFCite
