Research ArticleOpen accessIn the abstractLow-Noise High-Accuracy TOF Laser Range FinderShahram Mohammad Nejad, Saeed OlyaeeThis paper presents a new low-noise high-accuracy laser range finder based on the Time-Of-Flight (TOF) method. A Q-switched Nd:YAG laser at 1064 nm as a source and a SLIK avalanche photodiode as a detector are used. The optical section of the system including ZnS/MgF2 optical filter, designed by C++ and Zemax software, has been successfully implemented and tested. The quality … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,849 accessesView PDFCite
Research ArticleOpen accessIn the abstractA screen for Benzo(a)pyrene in Fish Samples From Crude Oil Polluted EnvironmentsChimezie Anyakora, Mohsen Arbabi, Herbert CokerSeveral studies have shown that exposure to Benzo(a)pyrene increases the risk of cancer. In this study several fish samples from Niger the Delta region of Nigeria were screened for the presence of Benzo(a)pyrene. The study was carried out using Gas chromatograph coupled to a mass spectrometry detector. Benzo(a)pyrenes in the samples were identified through both retention time match with authentic … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 6,766 accessesView PDFCite
Research ArticleOpen accessIn the abstractImprovement of Nuclear Track Density Measurements Using Image Processing TechniquesA. Mostofizadeh, X. Sun, M. R. KardanThe well known edge detection methods were applied to evaluate accuracy and precision of nuclear track densitometry of polycarbonate detector. All measurements carried out in two cases of before and after improvement of track images. Considering the overlapping phenomenon -including double and triple tracks- experimental and statistical results showed that not only each particular edge detection method affects the accuracy … …American Journal of Applied Sciences, Vol. 5, Issue 2 · 28 Feb 2008 · 7,427 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Modeling Approach for Collision Avoidance in Robotic SurgeryReza Ramezanifard, Javad Dargahi, Siamak Najarian, Farhad Tabatabai GhomsheWe present a new system that can be used in combination with an array of ultrasonic piezoelectric sensors and has application in surgical navigation procedures. Using the proposed assembly, the maneuverability of the surgical tools can be enhanced and the incidence of potentially damaging contact with non-target tissue can be reduced. The emphasis of our work was based on controlling … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 6,795 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Physical Refining on Palm Vitamin E (Tocopherol, Tocotrienol and Tocomonoenol)Chiew Wei Puah, Yuen May Choo, Ah Ngan Ma, Cheng Hock ChuahThis study reports the effect of physical refining on palm vitamin E including α- tocopherol, α-, γ and α-tocotrienols as well as α- tocomonoenol. A method using HPLC with fluorescence detector using normal phase silica column is described. An isocratic elution with n-hexane/THF/2-propanol (1000:60:4, by vol.) as mobile phase was used. The structure of the α- tocomonoenol was determined using … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 8,362 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of An Acoustic Temperature Transducer and its Application for Heater Temperature MeasurementMohammad A.K. Alia, Tariq Al MograbiRecent developments in temperature measurement have encouraged researchers to develop low-cost, simple structure, computerized generic transducers for environmental monitoring and industrial process control. The research presents a computerized technique which allows to measure temperature according to the variation of acoustic velocity (frequency) in a closed waveguide. Signal conditioning and processing was carried out using labVIEW (G Language) VIs. In order … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 6,817 accessesView PDFCite
Research ArticleOpen accessIn the abstractRange of Medium and High Energy Protons and Alpha Particles in NaI ScintillatorOnder KabadayiWe have calculated the range of proton and alpha particle in NaI scintillator which is a commonly used substance in scintillation detector manufacturing. The stopping power of proton and alpha particle in NaI is calculated first by using the theoretical treatment of Montenegro et al.[1]. The range calculation has been performed by using a technique that we developed in the … …American Journal of Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2004 · 6,946 accessesView PDFCite
Research NotesOpen accessIn the abstractMetadata Stewardship and Quality in Telecom SectorBhola Gan Chaudhuri, Shalli RaniThe spread of the telecom network infrastructure, constellations of satellites and the use of the Internet of Things (IoT) have brought about unprecedented volumes of heterogeneous information which facilitate the contemporary monitoring systems of the environment and the earth. Metadata control and information quality have also become significant in the telecom industry in controlling data reliably, enhancing data services, and … …Journal of Computer Science, Vol. 22, Issue 10 · 22 Oct 2026 · 335 accessesView PDFCite
Research ArticleOpen accessIn the abstractSM-SCAM YOLO: Enhancing Object Detection with Multi-Scale Module and Spatial Channel Attention MechanismShanmuga Sundari Mariyappan, Kayalvizhi Mohan, K. B. K. S. DurgaDetecting tiny objects remains a significant hurdle in computer vision, primarily due to scale variation, occlusion, and the loss of detail in low-resolution features. Although YOLO-based detectors are popular for their speed and efficiency in real-time tasks, they often struggle with accurately identifying small objects because of information loss during downsampling. This study introduces an improved YOLO-based model that integrates … …Journal of Computer Science, Vol. 21, Issue 6 · 12 Jun 2025 · 3,921 accessesView PDFCite
