We present an architecture in support of intelligent agent-mediated, behavioral interventions in special education programs for individuals with Autism Spectrum Disorder (ASD). The proposed architecture is a derivative of the Procedural Reasoning System (PRS) architecture with representative, inter-pretative, reasoning, knowledge-based, and procedural control components abstracted from the physical...
The More Electric Aircraft (MEA) emphasizes the utilization of electrical power as opposed to hydraulic, pneumatic, and mechanical power for optimizing aircraft performance and life cycle cost. The main sources of regenerative energy in the more electric aircraft power distribution system are the aircraft actuation systems: ailerons, rudder, flaps, spoilers, horizontal stabilizers and others. Instead...
When designing an autonomous All-terrain Vehicle (ATV) one must ensure that the communications paths to all major subsystems use a robust electrical signaling protocol. One such protocol is the CAN bus. This paper describes an effort to utilize a CAN bus to connect existing and new hardware on an ATV. The work involved a redesign of the braking control system as well as the throttle controls. The...
The Simulation Environment for Autonomous Robots (SEAR) has been updated to include new sensors that are more usable and customizable than in previous iterations. The simulator is now also fully integrated into robotics middleware MyRobotLab (MRL) allowing users to access other external libraries and use multiple programming languages to set up and control a simulation. SEAR interfaces with user code...
Imaging based techniques provide for a way for reconstructing surfaces using Shape from shading algorithms. Adding the convenient approximation of target wave fields by superposition of simple plane waves a new greedy algorithm for reconstruction of water surface is introduced. The algorithm developed optimizes each wave-front for several parameters until the least squares error is minimum. The methodology...
In this paper, a simplified approach to modeling Maximum Power Point Tracking (MPPT) for photovoltaic (PV) applications, and a simple procedure for implementing an approximation to MPPT sometimes referenced as the “constant voltage” (CV) method, are presented. To develop these concepts, the photovoltaic source is first modeled. A simplified model of the means for adjusting the photovoltaic source...
This paper presents an effective approach for reducing parasitic resistance of a CMOS negative inductor with a single compensating resistor. A compensating resistor is used to mitigate the effect of parasitic resistance with quadratic frequency dependence. The undesired parasitic effect is induced by the inevitable finite drain-source resistance of the input CMOS transistor of the most common Linvill...
Olfactory-based mobile robots use odors as a guide to navigate and track in the unknown environments. The key issue of localizing the odor plume source is how to trace odor plume effectively. This paper presents an effective olfactory-based planning and search algorithms for using on mobile robots. The algorithms are based on Bayesian inference theory and artificial potential field methods. The Bayesian...
Current conveyors can be used as building blocks for implementing non-Foster circuits such as negative capacitors and negative inductors that are useful in extending bandwidth in metamaterials. In the present paper, measured results are presented for a prototype integrated circuit current conveyor negative capacitor. This circuit has been fabricated in a 0.5 micron CMOS process following previous...
In this paper the author describes his experience in the delivery of a series of workshops providing an introduction to robotics. The workshops were attended by a group of high school students with an interest in the area who did not have previous knowledge of the elements that were presented. These elements included basics of the C/C++ language, including variables, data types, operators, decision/iteration...
According to the US Bureau of Labor and Statistics the job outlook for computer scientists and engineers is stellar for the long term—President Obama and industry leaders encouraged colleges to graduate 10,000 more engineers a year. Computer science and engineering salaries are high, but yet it is unlikely that the number of technology majors will meet the projected demand. Sadly, for many students...
Social Media (SM) data are growing, and SM is becoming an acceptable part of daily life for billions of people around the world. Extracting information from Social Networking Sites (SNS) can provide great challenges as well as opportunities. Using SM data beyond day-to-day communication can provide additional values. There is much research and many products that are dedicated to take SNS beyond communication...
A downlink “feedback” channel for an algorithm of LTE Femtocell Inter-cell Interference mitigation is designed in this paper. Specifically, in the receiver, a blind-detection method is established in order to correctly decode the signal transmitted. The simulation result shows that the designed channel would have low block error ratio (BLER). A simulation was implemented on DSP, and results also show...
In this paper, we investigate the performance of classification of protein crystallization images captured during protein crystal growth process. We group protein crystallization images into 3 categories: noncrystals, likely leads (conditions that may yield formation of crystals) and crystals. In this research, we only consider the subcategories of noncrystal and likely leads protein crystallization...
The paper addresses the calculation and theory involved in the analysis of detection and measurement of the shape of a water surface using laser beam reflections. The experiment is carried out in a closed environment and the method is developed mainly for indoor testing. A set of general equations are formulated to describe the water surface based on the set of data collected from the measurements...
There is increasing interest in impedance-matching methods that use non-Foster circuits to provide wideband operation in a variety of microwave devices such as antennas and metamaterials. In addition, many of these prior non-Foster circuits employ bipolar negative impedance converter designs, and it is advantageous to move such designs into CMOS. Therefore, the present work provides new measured results...
Because fog conditions are a major concern for transportation safety, it is vital that low cost devices be developed to warn of low visibility conditions. This paper describes the process by which a low-cost standalone and portable fog detection apparatus was designed, developed and tested using an optical transmissometer technique. Extensive testing was performed to validate and calibrate the device...
Efficient sound source detection and location with microphone arrays is important for many applications, including teleconferencing, surveillance, and smart rooms. While the steered response power algorithms exhibit robust performance relative to other approaches, their applications are limited by the high computational load required. For dynamic auditory scenes, the entire space must be scanned at...
