The radio magnetotellucic (RMT) method originates from (Tikhonov, 1950) and (Cagniard,1953) who discovered the possibility to estimate resistivity in the Earth’s subsurface using naturally occurring telluric currents. This through measuring the surface impedance of electromagnetic waves. Later (Paal, 1965) makes use of electromagnetic plane-waves originating from radio transmitters that operates in the very low frequency range (10 − 30kHz). These plane waves artificially induce telluric currents which can then be used to estimate resistivity in shallow subsurface. It is hence the source of the electromagnetic wave inducing the telluric current that named the RMT method accordingly. It’s then shown by (Bastani, 2001) that the signal can be measured in an even broader band (10 − 250kHz) to gain a better vertical resolution. Finally, frequency of the electromagnetic wave is affecting the skin depth and one can therefore estimate the depth of resistivity layers in the subsurface. In this thesis a data processing algorithm has been developed, based on the work in (Bastani, 2001), that processes RMT field data. Impedance, resistivity among other quantities is calculated. One can then export this data and use it in existing modeling software. New processing parameters has been implemented and its effect on the data set investigated. The software is implemented in matlab, and tested with synthetic data and data measured at Blötberget, Sweden. However, work is still to be done due to field equipment malfunction during measurements at Blötberget. This rendering an, at least partly, faulty data set. Therefore one cannot completely exclude calibration issues until a clean data set is taken. / Den radio magnetotelluriska (RMT) metoden har sitt ursprung i (Tikhonov, 1950) och (Cagniard, 1953) arbete där strukturen hos geologisk resistivitet uppskattas med hjälp av naturligt förekommande elektriska jordströmmar. Detta genom att mäta den elektromagnetiska vågimpedansen vid markytan. Sedan använder (Paal, 1965) sig av elektromagnetiska planvågor från lågfrekventa radiosändare (10 − 30kHz), som artificiellt inducerar jordströmmar, för att uppskatta resistiviteten i mer ytligt underliggande geologisk struktur. Det är således källan till den inducerade jordströmmen som namngett RMT-metoden. Det är sedan påvisat av (Bastani,2001) att man kan använda sig av frekvenser i ett bredare spektrum (10 − 250kHz) för att få ökad vertikal upplösning. Slutligen påverkar frekvensen hos den elektromagnetiska vågen inträngningsdjupet och på så sätt tillåts det att uppskatta resistiviteten vid ett särskilt djup. I denna studie har en databehandlingsalgorithm utvecklats, baserat på arbete utfört av (Bastani, 2001), som bearbetar RMT fältdata. Impedans och resistivitet samt andra storheter beräknas för att sedan kunna exporteras och användas i existerande modelleringsprogramvara. Programvaran är skriven i matlab, och dess funktionalitet har prövats med syntetisk data samt data från Blötberget, Sverige. Även påverkan av olika processparametrar har undersökts. Detta har gjorts med framgång, men arbete återstår för att fullständigt verifiera korrekt implementering då utrustningen som användes för insamling av fältdata vid Blötberget felade. Därför kan kalibreringsproblem i programvaran inte helt uteslutas.

In this thesis a buck converter has been developed to be used as a test bench in power electronics laboratory. For this purpose, first, steady-state and small-signal analyses of a buck converter is carried out, then open-loop and closed-loop control of the converter are developed and simulated. Then, the circuit is manufactured and tested. The test results are compared with the simulation results. Finally, an experimantal procedure is prepared to enable the students to perform the experiment in the laboratory with the test bench developed.

A Stewart Platform robot was designed, constructed, and programmed for use in Cal Poly’s ME 423 Robotics: Fundamentals and Applications laboratory section. A Stewart Platform is a parallel manipulator robot with six prismatic joints that has six degrees of freedom, able to be defined in both position and orientation. Its purpose is to supplement parallel robot material covered in lecture. Learning objectives include applying and verifying the Stewart Platform inverse kinematics and investigating the Stewart Platform’s operation, range of motion, and limitations. The Stewart Platform geometry and inverse kinematics were modeled and animated using MATLAB. The platform was then built using linear actuators, magnetic spherical bearings, and acrylic plates. Control of the Stewart Platform is achieved using an Arduino Due and a custom HexaMoto shield. Users interact with the system using a GUI created with MATLAB’s App Designer.

In the Black-Scholes model, the volatility considered being deterministic and it causes some inefficiencies and trends in pricing options. It has been proposed by many authors that the volatility should be modelled by a stochastic process. Heston Model is one solution to this problem. To simulate the Heston Model we should be able to overcome the correlation between asset price and the stochastic volatility. This paper considers a solution to this issue. A review of the Heston Model presented in this paper and after modelling some investigations are done on the applet. Also the application of this model on some type of options has programmed by MATLAB Graphical User Interface (GUI).

Ball mill grinding is an important operation in the processing of most minerals, in that it may be used to produce particles of the required size and shape, to liberate minerals from each other for concentration purposes, and to increase the powder surface area. Grinding of minerals is probably the most energy consuming task and optimization of this operation has vital importance in processing plant operations to achieve the lowest operating costs. Predicting the complete product size distribution, mill specifications and power draw are important parameters of this optimization. In this study, a computer simulation program is developed in MATLAB environment to simulate grinding operations using the kinetic model in which comminution is considered as a process continuous in time. This type of model is commonly and successfully used for tumbling grinding mills having strongly varying residence time as a function of feed rate. The program developed, GRINDSIM, is capable of simulating a ball mill for a specified set of model parameters, estimating grinding kinetic parameters from experimental batch grinding data and calculating continuous open and closed-circuit grinding behavior with mill power input. The user interacts with the program through graphical user interfaces (GUI&rsquo / s).
