There can be many. By their nature invasive tumors spread from tissue to tissue, abduct themselves to cause new tumors. In many of the human biological parts, CT scan has given an accurate approach for early and successful detection of the cancerous tumors. But there were cases where diagnosis with CT scan images failed and resulted in many false positives. In economically backward countries these false positives raised the notifying concern from women who cannot afford multiple diagnosis tests. Due to change in biological metabolism the growth of the breast fat in women to considerably abnormal size is the main cause for false positives. In many of the images under study, this huge thick breast fat layer led to the rise of misclassification rate with false positives. Rendering societal help is a need for an accurate mechanism that can reduce the false positives at an initial diagnosis itself. The proposed method introduces a novel constraint-based algorithm to classify a mammogram image as cancerous, aiming to reduce false positives. Our proposed deep learning algorithm WOMT is trained with Wasserstein Distribution constraints that are derived from mass transfer of cancerous patches to non-cancerous patches. Our experimental simulations with a deep learning model trained with these constraints resulted in reduced false positives.

The major issue arises at the efficiency of these engines. Every attempt made to improve these engines tends to attain the maximum efficiency. The study is about the effects of air swirl in the cylinder on its performance. Here a single cylinder direct injection diesel engine is used for study. For obtaining different swirl intensities the following design parameters have been changed the piston crown, cylinder head and inlet duct. By changing the piston crown design the enhancement in the turbulence inside the cylinder is achieved. Also grooves are made to achieve the increase in swirl intensity for better mixing of fuel and air.

The key challenge to use this technology is removing CO2 from syngas (H2+CO+CO2) before sending to turbine. Conventional solvent based absorption techniques need cooling of syngas to facilitate scrubbing process. This limitation results in significant energy penalty and reduced efficiency. Pressure Swing Adsorption (PSA) is a widely accepted technique for CO2 capture at elevated temperatures. PSA process is characterized by preferential adsorption of desired gas species on a porous adsorbent at high pressure and recovery of the same at lower pressure. However main issues of this technology are low recovery rate, development of suitable regenerable adsorbents for high temperature applications. Key factors that will decide the commercial worthiness of adsorbents are selectivity, stability, adsorption/desorption ...

This is because the CO 2 will be at higher pressure (requires smaller equipment) thereby making the separation process efficient and easy for sequestration. However the challenges remain to exploit this technology are; (i) it can only be applied for new plants since the separation process becomes integral part of combustion (results in higher down times), and existing plant cannot be retrofitted, (ii) the technology is not as mature as other counterparts and cannot be applied for large scale power production, (iii) higher energy penalty due to cooling of syngas for CO 2 separation with conventional methods. These issues have led worldwide researchers to focus on overcoming the challenges and make the technology of future. From the research of past decade, it is evident that CO 2 separation by adsorbents is best choice. Due to inherent disadvantages of process such as limited operating temperatures, recovery and purity of CO 2 , recovery ®eneration energy penalty, much of research in focused on developing enhanced adsorbents and processes. In this paper we present different techniques and materials developed by researchers in the past decade and also present future scope for pre-combustion capture applied to IGCC.

The problem being NP-hard, ANNs is one of the effective methods of solving in a polynomial time. The performance of the network depends on type of network architecture and the training algorithms. In this paper an attempt is made to design optimum feed-forward back-propagation network architecture with respect to the training algorithm and number of neurons in the hidden layer. The results show that Levenberg-Marquardt training algorithm (trainlm) is faster and accurate.

More than 80% of our energy comes from the combustion of fossil fuels, which will still remain the dominant energy source for years to come. It is agreed that carbon dioxide produced from the combustion process to be the most important anthropogenic greenhouse gas leading to global warming. It is well accepted fact that the gasification technology is the only solution for both these issues. The technology is yet to mature for large scale commercialization. Main issues hindering full exploitation of this technology are higher capital costs, limitations on feed stock flexibility, limited range of operating conditions, energy penalty of syngas cleaning, and limited conversion efficiency. Researchers from across the world are focusing on developing technology. In this paper we present the significant developments took place during the past decade.
