A New Multilevel Thresholding Method Using Swarm Intelligence Algorithm for Image Segmentation  [PDF]
Sathya P. Duraisamy, Ramanujam Kayalvizhi
Journal of Intelligent Learning Systems and Applications (JILSA) , 2010, DOI: 10.4236/jilsa.2010.23016
Abstract: Thresholding is a popular image segmentation method that converts gray-level image into binary image. The selection of optimum thresholds has remained a challenge over decades. In order to determine thresholds, most methods analyze the histogram of the image. The optimal thresholds are often found by either minimizing or maximizing an objective function with respect to the values of the thresholds. In this paper, a new intelligence algorithm, particle swarm opti-mization (PSO), is presented for multilevel thresholding in image segmentation. This algorithm is used to maximize the Kapur’s and Otsu’s objective functions. The performance of the PSO has been tested on ten sample images and it is found to be superior as compared with genetic algorithm (GA).
MRI Evaluation of Acute Internal Derangement of Knee  [PDF]
Venkateshwaran Arumugam, Ganesan Ram Ganesan, Paarthipan Natarajan
Open Journal of Radiology (OJRad) , 2015, DOI: 10.4236/ojrad.2015.52011
Abstract: Introduction: Internal derangement of the knee is a blanket term used to cover a group of disorders involving destruction of the normal functioning of the ligaments or cartilages. MRI provides excellent soft tissue contrast and is capable of evaluating the soft tissue and bony structures in multiple imaging planes which provide significant advantage in IDK. Methods and Materials: A prospective study of hundred twenty patients who underwent MRI for the diagnosis of internal derangement of knee between the period January 2013 and January 2015 was conducted. All the patients gave a history of knee joint pain following trauma and clinically suspected to have meniscal and ligament tears. Patients were evaluated using Philips intera R 11 1.5 T with pulsar gradient system using a sensor extremity coil. Results: Commonest lesion detected in our study was ACL tear followed by meniscal tear and medial collateral ligament injury. The most common sign of cruciate ligament injury was hyper intensity in the ligament. Grade 3 was the most common grade of meniscal tear. Conclusion: MRI is unique in its ability to evaluate the internal structure as well as the surface of the meniscus. Many anatomical variants can mimic a tear on MRI. MRI is an excellent non invasive modality for imaging the knee.
Is Distal Femur Locking Plate a Superior Implant in Distal Femur Fracture?  [PDF]
Anil Chander, Ganesan Ram Ganesan, Vignesh Jayabalan
Open Journal of Orthopedics (OJO) , 2015, DOI: 10.4236/ojo.2015.59035
Abstract: In spite of advances in techniques and improvements in surgical implants, confusion still prevails regarding use of specific implants in distal femur fracture. Fractures in the distal femur have posed considerable therapeutic challenges throughout the history of fracture treatment. Most of these surgical failures were due to inadequate fixation of the fracture fragments. The Aim of the study is to determine whether distal femur locking plates are superior implants than dynamic condylar screw and distal femur nail. A prospective and observational study was done in Department of Orthopaedics and Traumatology, Sri Ramachandra Medical Collage, Chennai between Jan. 2011 and Jan. 2015. Patients with distal femoral fractures, admitted into the hospital, were treated using various modes of internal fixation and followed up over a period of six months to one year and their functional outcome was evaluated. The functional and radiological assessment of patients during follow-up was done using Neer’s criteria. The use of any one of the implant, i.e. distal femur locking plates, dynamic condylar screw or distal femur nailing for internal fixation, depends on the type of fracture and the pre operative planning and intra operate decision of the surgeon. In our study, 38% of fractures treated by Dynamic condylar screw, 72% of fractures treated by distal femur locking plate and 42% of fractures treated by Distal femur supracondylar nail had excellent/satisfactory results. Locking plates had better outcome in both extra-articular and intra-articular group. They also had better outcome in both younger and older age groups.

Michel Tremblay : serial-adaptateur de pièces fran aises
Sathya Rao
Intercambio , 2010,
Abstract: A well-know playwright and novelist, Michel Tremblay is also a prolific translator and adaptator of theatre plays. Yet there are very few studies devoted to this aspect of his work which so far encompasses almost thirty adaptations and translations of plays, mostly from the United States. This article sets out to show that these practices are to be understood within a dynamic perspective that sees the progressive replacement of ideology by pragmatic considerations. Our study will focus on various adaptations of French plays as they illustrate the very complexity of the adaptation process as performed by Michel Tremblay.
Traduction et transmission dans L'étrange Destin de Wangrin
Sathya Rao
Intercambio , 2008,
Abstract: This articles proposes a postcolonial reading of L’étrange destin de Wangrin ou les roueries d’un interprète by Amadou Hampaté Ba. Such a reading is particularly relevant as it highlights the pattern of ambivalence at the core of the novel while bringing light on its inner complexity as well as profound actuality. As it will be shown, this complexity can be apprehended in terms of both an economics and ethics of transmission.
Sequential Approach with Matrix Framework for Various Types of Economic Thermal Power Dispatch Problems  [PDF]
Srikrishna Subramanian, Ganesan Sivarajan
Energy and Power Engineering (EPE) , 2010, DOI: 10.4236/epe.2010.22016
Abstract: This paper presents a sequential approach with matrix framework for solving various kinds of economic dispatch problems. The objective of the economic dispatch problems of electrical power generation is to schedule the committed generating units output so as to meet the required load demand while satisfying the system equality and inequality constraints. This is a maiden approach developed to obtain the optimal dispatches of generating units for all possible load demands of power system in a single execution. The feasibility of the proposed method is demonstrated by solving economic load dispatch problem, combined economic and emission dispatch problem, multiarea economic dispatch problem and economic dispatch problem with multiple fuel options. The proposed methodology is tested with different scale of power systems. The generating unit operational constraints are also considered. The simulation results obtained by proposed methodology for various economic dispatch problems are compared with previous literatures in terms of solution quality. Numerical simulation results indicate an improvement in total cost saving and hence the superiority of the proposed method is also revealed for economic dispatch problems.
Diminution in Error Approximation by Identity Authentication with IPAS for FTLSP to Enhance Network Security  [PDF]
Kuljeet Kaur, Geetha Ganesan
Journal of Information Security (JIS) , 2013, DOI: 10.4236/jis.2013.44022

In this paper, we have proved the diminution in error approximation when identity authentication is done with Ideal Password Authentication Scheme (IPAS) for Network Security. Effectiveness of identity authentication parameters for various attacks and security requirements is verified in the paper. Result of analysis proves that IPAS would enhance the transport layer security. Proof of efficiency of result is generated with drastic diminution in error approximation. IPAS would have advanced security parameters with implemented RNA-FINNT which would result in fortification of the transport layer security protocol for enhancement of Network Security.

Fault Diagnostics on Steam Boilers and Forecasting System Based on Hybrid Fuzzy Clustering and Artificial Neural Networks in Early Detection of Chamber Slagging/Fouling  [PDF]
Mohan Sathya Priya, Radhakrishnan Kanthavel, Muthusamy Saravanan
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.712335
Abstract: The slagging/fouling due to the accession of fireside deposits on the steam boilers decreases boiler efficiency and availability which leads to unexpected shut-downs. Since it is inevitably associated with the three major factors namely the fuel characteristics, boiler operating conditions and ash behavior, this serious slagging/fouling may be reduced by varying the above three factors. The research develops a generic slagging/fouling prediction tool based on hybrid fuzzy clustering and Artificial Neural Networks (FCANN). The FCANN model presents a good accuracy of 99.85% which makes this model fast in response and easy to be updated with lesser time when compared to single ANN. The comparison between predictions and observations is found to be satisfactory with less input parameters. This should be capable of giving relatively quick responses while being easily implemented for various furnace types.
