Guillaine Barre Syndrome after OPCAB Surgery  [PDF]
Murali Vettath, A. V. Kannan
Surgical Science (SS) , 2014, DOI: 10.4236/ss.2014.512082
Abstract: We report a successful treatment of the first reported case of Guillaine-Barre Syndrome (GBS) detected post Off Pump Coronary Artery Bypass Surgery (OPCAB). A 70-year-old man underwent OPCAB surgery for Triple Vessel Disease. In the post-operative period he developed respiratory distress with unexplained weakness in the limbs. CSF study confirmed Guillaine-Barre Syndrome. He was administered immunoglobulin therapy. The patient fully recovered and was discharged in good health.

Removal of hexavalent chromium from aqueous solution using activated carbon derived from palmyra palm fruit seed
A. Kannan, S. Thambidurai
Bulletin of the Chemical Society of Ethiopia , 2008,
Abstract: In this study, removal of chromium(VI) from aqueous solutions by Palmyra palm fruit seed carbon (PPFSC) and commercial activated carbon (CAC) was investigated. The metal adsorption capacity has been studied as a function of contact time, pH and carbon dosage. The adsorption yields increased with the increasing of adsorbent dosage and contact time, and subsequently reached the equilibrium. The suitability of the Freundlich and Langmuir models were also investigated for each chromium sorbent system. In order to understand the reaction mechanism, kinetic data has been studied using pseudo first order rate equation. The Lagergren’s constants were calculated for different initial concentrations of metal ions. The chromium(VI) ions could be rapidly removed from the sorbents by treatment with HCl acid and at the same time the regenerated sorbent could be used again to adsorb heavy metal ions. The suitability of this material for treatment of tannery wastewater was also examined.

An Escalated Approach to Face Tracking and Facial Expression Recognition from Video Files
R. Baskaran,A. Kannan
International Journal of Soft Computing , 2012,
Abstract: Tracking faces and identifying expression from a video files is a complex mining application due to the fact that even a delicate change in the emotion of the face could convey a great variation as an expression. This paper presents a robust novel method to track both male and female faces and recognize the facial expression in video files. Face localization in a digital image, which is being grabbed from the video source is performed using the hue-saturation and YC C based algorithms. Morphological algorithm over this region b r signals the eyes and mouth position in that region. Lips, eyebrows and eyelids are then identified. Distance between eyebrow and eyelid and the slope of the curvature of the lips are derived which facilitates in deciding the facial expression of the given digital image.

Extended Use of Vettath’s Anastomotic Obturator (VAO)  [PDF]
Vettath Prabhakaran Murali, Ismail E. Thazhkuni, Kannan A. Vellachamy
Surgical Science (SS) , 2011, DOI: 10.4236/ss.2011.29098
Abstract: Stroke rate in redo coronary artery bypass surgery has remained a stumbling block, where the aorta is used as origin for the top end of the vein graft. Avoiding the side-clamp on these redo aortas by using the Vettath’s Anastomotic Obturator (VAO) technique of anatomosing the vein graft could bring this down. We have also been able to use this technique in combined aortic valve replacement and CABG. These two situations where the VAO is used are elucidated here.
An Intelligent System for Lung Cancer Diagnosis from Chest Radiographs
H. Khanna Nehemiah,A. Kannan
International Journal of Soft Computing , 2012,
Abstract: In this study we propose an Intelligent Lung Cancer Diagnosis System (ILCDS) that has been developed to detect all possible lung nodules from chest radiographs. Our system uses image processing techniques and feed forward neural networks for detection and validation of nodules. Nodules are relatively low-contrast white circular objects within the lung fields. As nodules are the most common sign of lung cancer, nodule detection in chest radiographs is a major diagnostic problem. Even experienced radiologists have trouble while distinguishing the normal pattern of blood vessels and nodules that indicate the Lung cancer. Our work is centered around two major sub systems namely Nodule Detection Subsystem (NDS) and Nodule Validation Subsystem (NVS). The Nodule Detection Subsystem is constructed using wavelet based image-processing techniques such as Besov ball projections, Laplacian of Gaussian filter and Gabor wavelet networks which are used to remove the noise from the image, find the edges of the image and detect the nodule, size and its location. The NDS detects all the possible nodules and gives the nodule-detected image. The processed image shows all nodules in the chest radiograph. Since all nodules are not cancerous, the nodules detected by the NDS are validated by the NVS. The NVS is constructed using Feed forward neural network classifiers, which classifies the nodules into non-cancerous and cancerous nodules.
A Low-Power VLSI Implementation for Efficient Removal of Impulse Noise using CLA
Vinoth Kannan. A,Priyameenakshi .K
International Journal of Electronics and Computer Science Engineering , 2012,
Abstract: The impulse noise is caused by sharp, sudden disturbances in the image signal. Its appearance is randomly scattered white or black (or both) pixels over the image. In this paper, an efficient VLSI implementation for removing impulse noise using CLA is presented. Our result preserves the edge features and obtains excellent performances in terms of quantitative evaluation and visual quality The design reduce the low complexity impulse noise with low cost of hardware implementation. Compared with ripple carry adder, CLA(carry look-ahead adder) achieves a better performance and reduced carry propagation time. Here Xilinx power estimator(XPE) is used to compare the power required for VLSI implementation.
A method for importance sampling through Markov chain Monte Carlo with post sampling variational estimate
A. John Arul,Kannan Iyer
Statistics , 2013,
Abstract: We propose a method to efficiently integrate truncated probability densities. The method uses Markov chain Monte Carlo method to sample from a probability density matching the function being integrated. The required normalisation or equivalently the result is obtained by constructing a function with known integral, through non-parametric kernel density estimation and variational procedure. The method is demonstrated with numerical case studies. Possible enhancements to the method and limitations are discussed.
