Computational applications of noise sensitivity
This thesis is concerned with the study of the noise sensitivity of boolean functions and its applications in theoretical computer science. Noise sensitivity is defined as follows: Let f be a boolean function and let ... be a parameter. Suppose a uniformly random string x is picked, and y is formed …

Analysis and Design of Software-Based Optimal PID Controllers
… as load disturbance attenuation, robustness, and noise sensitivity. In this thesis, a MATLAB-based software tool is used to solve a constrained optimization problem, with respect to all three requirements. This gives tuning of both the PID parameters and a low-pass filter time constant. A large …

Effectively Encoding SAT and Other Intractable Problems into Ising Models for Quantum Computing
… but current technology is limited by noise sensitivity. Quantum Annealing is an alternative approach that uses a noisy quantum system to solve a particular optimization problem. Problems such as SAT and MaxSAT need to be encoded to make use of quantum annealers. Encoding SAT and MaxSAT …

A comparative study of neural network algorithms.
… speed of the trained network for test data and noise sensitivity. The Multi-layer feed forward neural network is trained using the Fast training algorithm and delta rule training algorithm. Then both algorithms are compared for speed and generalization capability of Optical Character Recognition …

A tunable Bose-Einstein condensate for quantum interferometry
… research in which the achievable interferometric sensitivity is bounded by the atomic shot noise. Until a few years ago the employment of BECs in such devices was strongly limited by the effect of the interactions between the condensed atoms. This obstacle is today removable exploiting interaction …
