With the increasing demand for electrical power and the growing need for the restructuring of the power industry, electric power systems have become highly complex with inherent complicated dynamics. Therefore, the study of power system stability has continued to receive significant attention from both academic researchers and industrial practitioners. This thesis focuses on supervisory wide-area control for rotor angle stability of multi-machine power systems using Linear Quadratic Gaussian/Loop Transfer Recovery (LQG/LTR) control theory with guaranteed robustness. The supervisory controllers are developed in both continuous-time and discrete-time framework and their performances and robustness are assessed using both frequency-domain tools, and time-domain simulation results. The impact of the communication time-delays that commonly exist in wide-area power system control on the performance and robustness of the closed-loop system is investigated. In particular, different methods of incorporating such time-delays into the design of the supervisory LQG controller are considered. This thesis proposes a modified supervisory LQG controller that utilizes the Extended Kalman Filter to estimate the unknown/varying time-delays. Simulation results obtained using numerical examples involving non-linear power system models demonstrate the benefits of the proposed scheme for both time-invariant and time-varying delays. The resulting supervisory control scheme is well suited for maintaining power system stability in the presence of communication time-delays.

Early and intensive behavioral intervention outcome research includes descriptions of intervention variables that may increase treatment success. This study was designed to develop an observation system that incorporates and expands on some of these variables. Measures include the number of interventionist teaching units, types of skills addressed during instruction, consequences programmed by interventionists, and engagement with teaching materials. This system allowed for a view of the differences in teaching behaviors among the participants. It is proposed that this observation system is a start toward standardized intervention measures that can be applied to evaluate varied treatment models. Such standardization can help in ensuring that all children have access to evidence-based services.

El presente trabajo de investigación propone determinar el rango aceptable de variabilidad en el sistema de medición de los contenidos de cobre y oro en el concentrado, entre el almacén de acopio en puerto y el punto de despacho en mina, mediante la realización de una serie de análisis de las variables dentro del proceso de estudio a nivel de toma de muestras, preparación de la muestra, análisis en laboratorio y métodos estadísticos empleados, con la finalidad de determinar si el impacto económico para la empresa es significativo. Para lo cual se ha descrito el análisis económico del sector minero a nivel nacional e internacional. He allí de donde viene la importancia de las diferencias de los contenidos de cobre y oro entre los puntos de despacho y acopio de una unidad minera. Es decir, si no se tiene identificado cuales son las variables o rangos aceptables de las diferencias de cobre y oro no se podrá determinar cuál es el impacto económico real en la compañía. El presente trabajo ha utilizado el método estadístico Anova y la pruebas de hipótesis t , así como análisis del sistema de medición MSA (Measurement System Analysis) usando Gage R & R, lo que nos ha permitido determinar que los sistemas de medición en ambos lugares (mina y almacén de acopio) se tiene que mejorar a través de estandarización de procesos: procedimientos de muestreo, capacitación a operarios, implementación y calibración de equipos similares, balances semanales entre ambos puntos. Esto nos permitirá disminuir la variabilidad entre los resultados de cobre y oro tanto en mina como en el almacén de acopio. / The present research work proposes to determine the acceptable range of variability in the measurement system of the copper and gold contents in the concentrate, between the storage warehouse in port and the point of dispatch in the mine, by carrying out a series of analysis of variables within the study process at the level of sampling, sample preparation, laboratory analysis and statistical methods used, with the determination to determine if the economic impact for the company is significant. For which the economic analysis of the mining sector at national and international level has been described. This is where the importance of the differences in copper and gold content between the dispatch and storage points of a mining unit comes from. In other words, if the acceptable variables or ranges of the copper and gold differences are not identified, the real economic impact on the company cannot be determined. The present work has used the Anova statistical method and the hypothesis T tests, as well as analysis of the measurement system MSA (Measurement System Analysis) using Gage R&R, which has allowed us to determine that the measurement systems in both places (mine and storage warehouse) have to improve through the standardization of processes: sampling procedures, operator training, implementation and calibration of similar equipment, weekly balances between both points. This allows us to decrease the variability between copper and gold results both in the mine and in the storage warehouse. / Trabajo de investigación

Master thesis examines a selected part of electromagnetic compatibility. In this work, there is theoretically discussed how electromagnetic interference appears and how is spread through free space environment. To eliminate ambient interference signals, the measurements have been performed in anechoic chamber where the undesirable interference signals were suppressed. In the thesis, there are also described parameters of EMI receivers and limits of electromagnetic interference. The description of calculations of the antenna height for finding maximum intensity of electric field strength for standard measurement distance has been made. For proposed transformed measurement distance, calculations of intensity electric field with addition of parameters measuring antenna and object under test were performed. Correction curves for conversion intensity electric field have been obtained as the result.

The semiconductor industry was benefited by the advances in technology in the last decades. This fact has an impact on the sensors field, where the simple transducer was evolved into smart miniaturized multi-functional microsystems. However, commercially available gas and biological sensors are mostly bulky, expensive, and power-hungry, which act as obstacles to mass use. The aim of this work is gas and biological sensing using capacitive structures. Capacitive sensors were selected due to its design simplicity, low fabrication cost, and no DC power consumption. In the first part, the dominant structure among interdigitated electrodes (IDEs), fractal curves (Peano and Hilbert) and Archimedean spiral was investigated from capacitance density perspective. The investigation consists of geometrical formula calculations, COMSOL Multiphysics simulations and cleanroom fabrication of the capacitors on a silicon substrate. Moreover, low-cost fabrication on flexible plastic PET substrate was conducted outside cleanroom with rapid prototyping using a maskless laser etching. The second part contains the humidity, Volatile Organic compounds (VOCs) and Ammonia sensing of polymers, Polyimide and Nafion, and metal-organic framework (MOF), Cu(bdc)2.xH2O using IDEs and tested in an automated gas setup for experiment control and data extraction. The last part includes the biological sensing of C - reactive protein (CRP) quantification, which is considered as a biomarker of being prone to cardiac diseases and Bovine serum albumin (BSA) protein quantification, which is used as a reference for quantifying unknown proteins.

The increasing demand for electricity over the last few decades has not been followed by adequate growth in electric infrastructure. As a result, the reliability and safety of the electric grids are facing tremendously growing pressure. Large blackouts in the recent past indicate that sustaining system reliability and integrity turns out to be more and more difficult due to reduced transmission capacity margins and increased stress on the system. Due to the heavy loading conditions that occur when the system is under stress, the protection systems are susceptible to mis-operation. It is under such severe situations that the network cannot afford to lose its critical elements like the main generation units and transmission corridors. In addition to the slow but steady variations in the network structure over a long term, the grid also experiences drastic changes during the occurrence of a disturbance. One of the main reasons why protection relays mis-operate is due to the inability of the relays to adjust to the evolving network scenario. Such failures greatly compound the severity of the disturbance, while diminishing network integrity leading to catastrophic system-wide outages. With the advancement of Wide Area Measurement Systems (WAMS), it is now possible to redesign network protection schemes to make them more adaptive and thus improve the security of the system. Often flagged for exacerbating the events leading to a blackout, the back-up distance protection relay scheme for transmission line protection and the loss-of-field relay scheme for generator unit protection can be greatly improved from an adaptability-oriented redesign. Protection schemes in general would benefit from a power re-distribution technique that helps predict generator outputs immediately after the occurrence of a contingency. / Ph. D.

A high-resolution directivity measurement system at Brigham Young University has been renovated and upgraded. Acoustical treatments have been installed on the microphone array, professional-grade audio hardware and cabling have been utilized, and user-friendly MATLAB processing and plotting codes have been developed. The directivities of 16 played musical instruments and several loudspeakers have been measured by the system, processed, and plotted. Using loudspeakers as simulated musicians, a comprehensive analysis was completed to validate the system and understand its error bounds. A comparison and evaluation of repeated-capture to single-capture spherical systems was made to demonstrate the high level of detail provided by the 5 degree resolution system. Analysis is undertaken to determine how nonanechoic effects in anechoic chambers influence results. An overview of directivity measurement systems from the literature is provided as well as a dedicated discussion of the directivity measurement system at Brigham Young University.
