Abstract

Uterine Cervical Cancer is one of the prevalent forms of cancer in women worldwide. Most cases of cervical cancer can be prevented through screening programs aimed at detecting precancerous lesions. In this paper, novel methods have been proposed for automated probabilistic image segmentation of cervical cancer. The detection of cervical lesions is an important issue in image processing because it has a direct impact on surgical planning. We examined the segmentation accuracy based on a validation metric against the estimated composite latent gold standard, which was derived from several experts' manual segmentations. The distribution functions of the lesion and control pixel data were parametrically assumed to be a mixture of probability distributions with different shape parameters. We also estimated the corresponding receiver operating characteristic (ROC) curve over all possible decision thresholds. The automated segmentation yielded satisfactory accuracy with protean optimal thresholds.

Abstract

Suicide (self annihilation) is a common incident affecting the people of all classes throughout the globe. . It is a peculiar crime where both the accused and victim is same person. Attempt to suicide and abetment of suicide is punishable under Sec. 309 and Sec.306 of Indian Penal Code. Medicolegists should be very cautious regarding the opinion while dealing such cases because many times the exact cause and circumstance of the incident remains concealed. Thorough investigation, meticulous examination including visit to the scene of crime is utmost essential to take correct decision to avoid miscarriage of justice. Such a situation arose when a young married male person was admitted in unconscious state in hospital with history of attempt of suicide by hanging. The case was booked under Sec.309 of Indian Penal Code by the police. But presence of some unexplainable mysterious mechanical injuries over his body found during medicolegal autopsy following his death after eight (8) days put the forensic experts in a dilemma to rethink the background. This interesting case report is depicted here for better understanding of such similar incidences.

Abstract

High Performance Computing is mostly used for Scientific Research. Various atmospheric models are used across the world, but the Weather Research and Forecast (WRF) Model is a fully functional modeling system for atmospheric research and operational weather prediction communities. If considered the weather models through which we achieve real-time forecasting and climate prediction, they are very time-critical and need a strong scaling. In this scenario only clusters with faster nodes and processors are not enough. With the introduction of CUDA cards in market, the computing power has raised its bar. In this paper, we have emphasized on the efficiency and scalability of WRF model on ParamVayu a HPC cluster at National Center for Medium Range Weather Forecasting (NCMRWF) and also on the performance scalability using the GPU cards. This research was done for benchmarking WRF model performance using various interconnects viz. PARAMNet-3, Infiniband and Gigabit. The paper also discusses on ways to increase the performance by changing node to core configuration and the GPU acceleration of WRF model using GPU Tesla c1060.

Abstract

In India two out of three children suffer from various types of abuse be it physical, emotional or sexual. Though the reasons can be manifold, mostly the sufferers are unwanted children. The present case is about a two year old female child who was brutally beaten by her mother, upon provocation by the mother's lover and was thrown away in a river bank. Though found alive at the time of recovery, she died in the hospital four days later. Meticulous autopsy examination was corroborative with the said incidence with evidences of multiple injuries all over the body including various fractures of bones. This is a unique case report of brutal physical abuse of a child who paid for her mother's extramarital affair.

Keywords

Abuse, Unwanted Children, Brutally, Autopsy.
