Algorithmic Approaches For Protein-Protein Docking And quarternary Structure Inference - Mitra, Pralay
Molecular interaction among proteins drives the cellular processes through the formation of complexes that perform the requisite biochemical function. While some of the complexes are obligate (i.e., they fold together while complexation) others are non-obligate, and are formed through macromolecular recognition. Macromolecular recognition in proteins is highly specific, yet it can be both permanent and non permanent in nature. Hallmarks of permanent recognition complexes include large surface of interaction, stabilization by hydrophobic interaction and other noncovalent forces. Several amino acids which contribute critically to the free energy of binding at these interfaces are called as “hot spot” residues. The non...
RETHROTTLE : Execution Throttling In The REDEFINE SoC Architecture - Satrawala, Amar Nath
REDEFINE is a reconfigurable SoC architecture that provides a unique platform for high performance and low power computing by exploiting the synergistic interaction between coarse grain dynamic dataflow model of computation (to expose abundant parallelism in the applications) and runtime composition of efficient compute structures (on the reconfigurable computation resources). Computer architectures based on the dynamic dataflow model of computation have to be an infinite resource implementation to be able to exploit all available parallelism in all applications. It is not feasible for any real architectural implementation. When limited resource implementations are considered, there is a possibility of loss of...
Performance Enhancement Of Intrusion Detection System Using Advances In Sensor Fusion - Thomas, Ciza
The technique of sensor fusion addresses the issues relating to the optimality of decision-making in the multiple-sensor framework. The advances in sensor fusion enable to perform intrusion detection for both rare and new attacks. This thesis discusses this assertion in detail, and describes the theoretical and experimental work done to show its validity.
The attack-detector relationship is initially modeled and validated to understand the detection scenario. The different metrics available for the evaluation of intrusion detection systems are also introduced. The usefulness of the data set used for experimental evaluation has been demonstrated. The issues connected with intrusion detection systems...
Search On A Hypercubic Lattice Using Quantum Random Walk - Rahaman, Md Aminoor
Random walks describe diffusion processes, where movement at every time step is restricted only to neighbouring locations. Classical random walks are constructed using the non-relativistic Laplacian evolution operator and a coin toss instruction. In quantum theory, an alternative is to use the relativistic Dirac operator. That necessarily introduces an internal degree of freedom (chirality), which may be identified with the coin. The resultant walk spreads quadratically faster than the classical one, and can be applied to a variety of graph theoretical problems.
We study in detail the problem of spatial search, i.e. finding a marked site on a hypercubic lattice...
