Quantum Correlations Using Classical Detectors, Chamithri Adikarige Dec 2021

Quantum Correlations Using Classical Detectors, Chamithri Adikarige

Theses

Single photons are vital to quantum computing, information processing, and transportation. Popular single-photon experiments are one or two-photon interference, classification of the light source, and characterization of detectors. Currently, the most efficient detector in the telecom wavelength is the Superconducting Nanowire detector. How- ever, experiments have been successful in demonstrating single-photon measurements can be done with unconventional detectors. One such method employed an EMCCD camera to observe spatial correlations between pixels with single photons. This thesis aims to test non-single photon-counting PIN photodetectors to observe time-correlation measurement. The improved detection model uses a high-resolution 2GHz oscilloscope and a cross-correlation algorithm. …

Catastrophe theory is a mathematical technique for the qualitative analysis of system equations, defining the jump phenomena and sudden changes caused by smooth changes in the system parameters. This theory has been applied previously to the study of steady state stability of power system. This paper presents a new technique in the area of power system stability studies to describe steady-state voltage stability in terms of one of the catastrophe manifolds to which the power system can be fitted.

Well Design And Influence Of Ground Water Level On Pump Performance., Abdel-Razik Zidan

Mansoura Engineering Journal

A deep water well of 600 m depth was designed and drilled in the farm, college of agriculture Al-Qassim, fourteen stages turbine pump was selected. to be installed on this well, according to the total head and water discharge required for irrigation. A severe decline of ground water level will not provide the required water discharge and total head even if the pump works under its maximum speed. This could make a trouble shooting or damage to the pump unless its column pipe length will be increased to deal with the existing water level.

Neural Networks Applied To Grading Of Cup-Disk Ratio In Glaucomatous Cases., A. Tolba, S. Sitteen

Mansoura Engineering Journal

Automatic measurement of cup-disc ratio is a challenging problem. This problem could be efficiently solved with a neural network based learning technique. The eye signature renders the measurement of this ratio a tedious task. The physicians prepared maps for grading of this ratio. These maps classify the development of disease in a human eye in nine stages as shown in Figure 1. Neural networks and their solution time is very strongly dependent upon the initial random values of the synaptic connections and the order of pattern presentation to the input layer. Therefore it was necessary to study this phenomena and …

Waveform Estimation Techniques For Event-Related Bioelectric Signals: A Comparative Study Of Performance., Fatma El-Zahraa Abou-Chadi

Mansoura Engineering Journal

Many bioelectric signals result from the electrical response of physiological system to an impulse that can be internal (ECG signals) or external levoked potentials). A comparative study of performance of seven waveiorm estimation techniques used for event-related signals that are time-locked to a stimulus is presented in this paper Computer generated signals and noise for several signal-to-noise ratios (SNR's) are used to make ensembles of simulated noisy waveforms. The performance of each technique is numerically investigated using the root-mean-squared error and two well known SNR estimators. The results show that an adaptive impulse correlated filter (AICF) performs the best. It …

In this paper mathematical formulate were derived to express yarn crimp ratio in terms of weave structure, yarn spacing, and yarn diameter. It is discriminated between floated weaves and extended weaves. In floated weaves yarn spacing is constant and equal to yarn spacing at the point of intersection. In extended weaves, yarns are separated only at points of intersection. To increase accuracy and safe effort and time consumed in measuring yarn crimp ratio is determined by weighing crimped …

A developed sweep-line algorithm (SL) is introduced to find all sell-intersection points accurately and quickly. The previous work is limited to handle polygons that having no line-segments in parallel to $Weep-line directions. An invalid loop detection and removing (ILDR) algorithm is proposed. The invalid loops detection algorithm divides the polygon al self-intersection points into a set of small polygons, and re-polygonized them. The polygons are checked for direction; invalid polygons are always having inverse direction with the boundary polygon. The proposed algorithm has been implemented in Visual …

Factors Affecting The Natural Machine Damping Power In Series Compensated Power Systems., A. Sallam

Mansoura Engineering Journal

Studies of the application of series capacitor compensation in integrated power systems lead to consideration of the effects of the compensation upon the contribution arising from the natural damping of the generators. In general the series compensation is chosen because of the reduction in transfer reactance, but this paper shows that there is also an improvement in the natural positive sequence machine damping Automatic voltage regulator effects and the effects of feedback signals in such controls have been studied. The possibility of sub-synchronous resonance is taken into account.
