Single Incision Laparoscopic Surgery-An Overview and Current Status  [PDF]
Amit Goel
Surgical Science (SS) , 2012, DOI: 10.4236/ss.2012.310100
Abstract: Single incision laproscopic surgery is an alternative to conventional multiport laproscopy. Natural orifice transluminal endoscopic surgery term coined by a Consortium in 2005 remains a research technique with few clinical cases. Single incision surgery offers advantage of better cosmesis, reduced incisions, lesser hernias, decreased pain and infections. Long learning curves and cost of instrumentation are the difficulties encountered in its propagation. Single incision laproscopic surgery is an evolving technique for advanced laproscopic centers. This article outlines the overview of devices and instruments and the techniques, feasibility of single incision laproscopic surgery.

Abstract: Objective: Maxillofacial injuries are one of the commonest injuries encountered. Roentgenographic evaluation of maxillofacial trauma is of prime importance for diagnosis and treatment of these injuries. Study Design: Forty patients were evaluated in the prospective four-year study. We studied and evaluated the demography and diagnostic efficacy of clinical, plain radiography, and computed scan in maxillofacial trauma. Result: Road traffic accidents were the commonest cause of maxillofacial injuries. Patients having multiple fractures, mandibular fractures were the commonest. Conclusion: Computed tomography proved a useful adjunct in midfacial trauma.

Effect of PVP, PVA and POLE surfactants on the size of iridium nanoparticles  [PDF]
Anjali Goel, Neetu Rani
Open Journal of Inorganic Chemistry (OJIC) , 2012, DOI: 10.4236/ojic.2012.23010
Abstract: Commonly transition metal nano particle are synthesized by physical, chemical or electrochemical methods. In the present work colloidal iridium nanoparticles were synthesized by chemical oxidation method with different surfactants like poly vinyl pyrrolidone (PVP), poly vinyl alcohol (PVA) and poly oxyethylene lauryl ether (POLE). It was found that shape and size of Ir-nano particles resulted were related to kind of capping agent (surfactant) used. The characterization of the synthesized nano particle has been carried out by UV-vis, X-ray diffraction (XRD), FT-IR, scanning electron microscopy (SEM) and transmission electron microscopic (TEM) techniques. UV-vis and FT-IR confirm the oxidation of IrCl3 into IrO2 while XRD confirms the amorphous nature of the iridium nanoparticles synthesized. The morphology and size of the particle were confirmed by TEM. The average particle size determined by Scherrer equation was about 4.12 nm to 4.23 nm with PVP, 2.74 to 3.36 nm with PVA and 20.41 to 42.25 nm with POLE. Poly oxyethylene lauryl ether particles were not further analyzed because of their large size and less stability. Further particle size was confirmed with TEM, which was 4.5 nm with PVP and 7.0 nm with PVA. The particles are spherical with no agglomeration tendency.
Testability Estimation of Framework Based Applications  [PDF]
Noopur Goel, Manjari Gupta
Journal of Software Engineering and Applications (JSEA) , 2012, DOI: 10.4236/jsea.2012.511097
Abstract: Quality of software systems is highly demanded in today’s scenario. Highly testable system enhances the reliability also. More than 50% of test effort-time and cost are used to produce a highly testable system. Thus, design-for-testability is needed to reduce the test effort. In order to enhance the quality, productivity and reduced cost of the software organizations are promoting to produce the reuse-oriented products. Incorporating reuse technology in both aspects-software development process and test process may payoff many folds. Keeping this view, our study focus the testability of the object-oriented framework based software systems and identify that flexibility at the variable points of the object-oriented framework, chosen for framework instantiation, greatly affects the testability of object-oriented framework based software at each level of testing. In the current paper, we propose a testability model considering the flexible aspect of the variable point to estimate testability in the early phase, requirement analysis phase, of development process of the framework based software. The proposed model helps to improve the testability of the software before the implementation starts thus reducing the overall development cost.
A Multiobjective Optimization Method for Designing M-Channel NPR Cosine Modulated Filter Bank for Image Compression  [PDF]
Anamika Jain, Aditya Goel
Engineering (ENG) , 2015, DOI: 10.4236/eng.2015.72008
Abstract: This paper proposes a method to design multichannel cosine modulated filter bank for image compression using multiobjective optimization technique. The design problem is a combination of stopband residual energy, least square error of the overall transfer function of the filter bank, coding gain with dc leakage free condition as constraint. The proposed algorithm uses Non-dominated Sorting Genetic Algorithm (NSGA) to minimize the mutually contradictory objective function by minimizing filter tap weights of prototype filter. The algorithm solves this problem by searching solutions that achieve the best compromise between the different objectives criteria. The performance of this algorithm is evaluated in terms of coding gain and peak signal to noise ratio (PSNR). Simulation results on different images are included to illustrate the effectiveness of the proposed algorithm for image compression application.

Deepak Goel, Manish Mittal
World Journal of Neuroscience (WJNS) , 2015, DOI: 10.4236/wjns.2015.55034
Abstract: Objectives: To find out prescription patterns and seizure freedom with different mono-, duo- and poly-therapies used in various seizure disorders in Indian setting. Material and Methods: Subjects with seizures, not responding to first antiepileptic drug, were evaluated prospectively for a period of 6 months. Patients on various dual antiepileptic drugs (AEDs) prescriptions were prospectively analyzed for 1) the pattern and frequency of different duo-therapies; 2) etiological profile of patients in duo-therapy prescription; and 3) frequency of seizure freedom on various duo-therapy groups. Results: Among 2542 patients, 293 (11.5%) lost in follow-up and thus, 2249 (88.5%) were followed. 1324 (58.9%) had seizure freedom on mono-therapy, 532 (23.7%) required duo-therapy and only 45 (2%) were better controlled on poly-therapy. Among the subjects, who were on mono-therapy, Carbamazepine/Oxcarbazepine was the most commonly prescribed in 1285 (50.55%) patients as first drug followed by Valproate compound and Phenytoin. The most common duo-therapy used was combination of Valproate with Lamotregine, followed by Phenytoin and Phenobarbitone. Other mono-therapy and combinations are given in this paper. Conclusions: Duo-therapy was required and found to be effective in 23.7% of Indian patients with epilepsy. Selection of appropriate two drug combination is based on individual approach and overall clinical profile of patient.
Performance Analysis of Receive Diversity in Wireless Sensor Networks over GBSBE Models
Shivali Goel,Jemal H. Abawajy,Tai-hoon Kim
Sensors , 2010, DOI: 10.3390/s101211021
Abstract: Wireless sensor networks have attracted a lot of attention recently. In this paper, we develop a channel model based on the elliptical model for multipath components involving randomly placed scatterers in the scattering region with sensors deployed on a field. We verify that in a sensor network, the use of receive diversity techniques improves the performance of the system. Extensive performance analysis of the system is carried out for both single and multiple antennas with the applied receive diversity techniques. Performance analyses based on variations in receiver height, maximum multipath delay and transmit power have been performed considering different numbers of antenna elements present in the receiver array, Our results show that increasing the number of antenna elements for a wireless sensor network does indeed improve the BER rates that can be obtained.
STILLING BASINS BELOW OUTLET WORKS – AN OVERVIEW
H L Tiwari,,V.K.Gahlot,,Arun Goel
International Journal of Engineering Science and Technology , 2010,
Abstract: A stilling basins are transition structures constructed to dissipate excess energy confined by high velocity flow at the outlet of conduit or tunnel so that the flow beyond the basin does not endanger the stability of bed and banks of downstream channel. In a stilling basin kinetic energy causes turbulences and it is ultimately lost as heat and sound energy. there are several types of stilling basins which are used in various hydraulic structures like dam, canal, culvert etc. The type of stilling basin most suitable at a particular location mainly depends upon initial Froude Number and initial velocity of flow. This paper covers design principles and features of various stilling basins used for outlet works.

H.L.Tiwari,,Arun Goel,,V. K. Gahlot
International Journal of Engineering Science and Technology , 2011,
Abstract: This research paper presents an experimental study of end sill for new stilling basin models in dissipation of energy for a rectangular shaped pipe outlet of size 10.8cm x 6.3 cm. The models were tested for three Froude numbers namely 1.85, 2.85 and 3.85 in the laboratory. The new models are developed by changing the shape of end sill. The scour (magnitude and location) after the end sill were measured for each model. The results have indicated that for all flow conditions, the sloping end sill is more effective in lowering the downstream kinetic energy than other end sills tested,
