20110246831 | METHOD AND APPARATUS FOR OPERATIONAL-LEVEL FUNCTIONAL AND DEGRADATION FAULT ANALYSIS - An apparatus and method are provided for analyzing fault tolerance of a system, and performing “what if?” analysis for various fault-tolerant system design options. The fault tolerance analysis approach handles logical failures and quality faults emanating from loss of precision in signal values. The method can detect quality faults, which can allow systems to be built which are resilient to precision losses. Two analysis steps are provided, one static and another simulation-based, which are used in tandem to check the fault tolerance of an automotive or other system. While a simulation-based method checks fault-resilience under specific test cases and fault-scenarios, the static analysis method quickly checks all test cases and fault-scenarios. The static analysis method makes approximations while performing the analysis, and any fault detected is reproduced using the simulation-based method. All analysis operations are performed on operations-level behavioral models of the applications, thereby reducing the cost of analysis. | 10-06-2011 |

20130323767 | Method to Identify Liver Toxicity Using Metabolite Profiles - The present disclosure relates to a methodology that identifies the underlying mechanisms that lead to hepatotoxicity. This is done by using the alterations in cellular metabolite profiles obtained before and after therapy/drug treatment in combination with a model of liver metabolism. Subsequently, by using a covariance matrix adaptation followed by evolutionary selection, it compares the drug-induced metabolite profiles obtained experimentally with those generated using the in silico model, automatically shortlists potential parameters whose alterations could have produced the drug-treated metabolite profile. Values of these parameters are estimated by formulating an optimal control problem to minimize the differences between the model-generated metabolite values and experimentally observed data. The estimated parameters are given as an input to the homeostatic liver model and simulations are carried out, thereby the results providing a mechanistic explanation for the development of toxicity. | 12-05-2013 |

20140295518 | PROCESS FOR GENERATION OF HYDROGEN AND SYNGAS - The present invention is related to a process for generation of hydrogen and syngas based on biomimetic carbonation and photocatalysis. A path breaking way has been developed for generation of solar fuels in specific hydrogen by coupling biomimetic carbonation with photocatalysis. Efforts are being made worldwide to mimic the reaction for fixation of anthropogenic CO2 into calcium carbonate using carbonic anhydrase (CA) as a biocatalyst. CA is being employed to accelerate the rate of hydration of CO2 to form carbonate ions and proton. Presently carbonate is being precipitated from aqueous solution as calcium carbonate given a suitable saturation of calcium and carbonate ions by addition of appropriate buffer. A major breakthrough in the area of generation of solar fuels like hydrogen has been achieved by coupling biomimetic carbonation with photocatalysis. This approach may prove to be a revolutionary technical advancement required for hydrogen economy demanding carbon neutral hydrogen production. Also the production of hydrogen in addition to carbonates as end products during biomimetic carbonation may make the process commercially viable to be adopted by industries emitting carbon dioxide. The carbonate rich stream has been photocatalytically reduced to formaldehyde. This breakthrough thus opens new horizons in the area of carbon sequestration by virtue of the fact that end product of carbon sequestration is not only environmentally benign product of calcite but it would lead to the generation of clean energy including hydrogen, methane and methanol. Maximum hydrogen evolution has been observed up to 101.14 μmoles/mg of, free CA, 156.8 μmoles/mg of immobilised CA and 101.14 μmoles/mg of CA 6684.5 μmoles/mg of stabilised CA using TiO2/Zn/Pt as photocatalyst. The problem of using Zn as a metal donor has been overcome by illuminating the system. Hydrogen evolution to the tune of 84 μmoles/mg of CA has been observed for system with Zn as metal donor in the presence of Pt as co-catalyst with illumination. | 10-02-2014 |
