This paper describes development of a 32-bit embedded microcontroller board intended for a broad range of applications. In addition, three example applications are discussed. The first application is an embedded data logger installed on locomotives. This device has resources for recording analog and digital inputs, GPS position, GMT time, logging records to SDHC card and uploading periodically over...
During Aging muscle physiological properties change, which affect the Electropmyography (EMG) signals recorded by either surface electrodes or needle electrodes. In this paper, an surface EMG generation techniques has been presented by considering multilayer muscle model and physiologic behavior of type-I and type-II motor units during voluntary contraction from the latest findings in literature....
In this paper, the control of a class of linear model following systems with a full-state observer is investigated. We assume that the model dynamics are completely known and the order of the model can be different from that of the controlled plant. The observer-based controller is designed utilizing linear matrix inequality approach. The controller developed in this investigation is linear and under...
Equipped with camera, microphone, GPS and other sensors, together with convenient applications such as email clients, smartphones have a high potential to become a cost-effective intelligence gathering platform in a war zone. However, current smartphone applications are developed for civilian use. Due to lack of support for military requirements, such as confidentiality, smartphones may not be directly...
Several new Android smartphones support Near Field Communication (NFC). The Android SDK provides an NFC API that can be used to develop NFC applications that conduct peer-to-peer (P2P) data exchange. The Android emulator does not support P2P communication between instances of the Android Virtual Device (AVD). In addition to this constraint, P2P experimentation on actual smartphones is difficult due...
The Gas turbine technology has steadily advanced since its inception and emerged as a strong force in the generation market. It has been an active area of research. Research and development was one of the major keys to its success. The objective of this paper is to present a survey of two gas turbine designs available from two different companies i.e., General Electric (GE) and Westinghouse used in...
Oscillatory pathways are among the most important classes of biochemical systems with examples ranging from circadian rhythms and cell cycle maintenance. Mathematical modeling of these highly interconnected biochemical networks is needed to meet numerous objectives such as investigating, predicting and controlling the dynamics of these systems. Identifying the kinetic rate parameters is essential...
The conducting properties of core/shell nanoclusters of two different materials - one with a metal core/ semiconductor shell, and the other with a metal core/ insulator shell have been investigated. Experiments carried out for the two samples under the same conditions demonstrate distinct variations in the conducting properties of both. At increasing temperatures, the metal/semiconductor core/shell...
In 2010 a group of students at Embry-Riddle designed and built a robot capable of playing the popular videogame “Rockband.” The goal of the robot was to compete against human players in a score duel. Development of the robot presented many challenges that had to be overcome in order for the robot to be successful. This paper discusses the solutions to those challenges and the results of testing the...
Labeled datasets play a major role in the process of validating and evaluating machine learning techniques in intrusion detection systems. In order to obtain good accuracy in the evaluation, very large datasets should be considered. Intrusion traffic and normal traffic are in general dependent on a large number of network characteristics called features. However not all of these features contribute...
Agile software development methodologies, such as Scrum, have gained tremendous popularity and proven successful in quickly delivering quality Functional Requirements (FRs). However, agile methodologies have not adequately modeled Non-Functional Requirements (NFRs) and their potential solutions (operationalizations) with FRs in early development phases. This research proposes three fundamental agile...
This research describes the construction of a discrete event simulation model of the operations of a major emergency department (ED) in Melbourne, FL. Real data were used to fit distributions to patients' interarrival times, and to validate the model using statistical analyses. After meetings with the ED's management personnel, a major problem identified was the constant occurrence of bottlenecks...
Implementing the smart grid will require intelligent interaction between the power generating and consuming devices, which is achieved by installing devices capable of processing data and communicating it to various parts in the grid. The role of embedded processors will be to achieve high performance in the given real time situations. The embedded processors carry out tasks similar to security encryption,...
Portable Impedance/Reflected Power Meter consists of an integrated system with 1) a portable circuit designed to make voltage and current measurements in a power-line carrier circuit, 2) a digitizer (NI USB-5132) capable of sampling signals in the frequency range of 30 kHz to 500 kHz, and 3) a LabVIEW application configured to acquire the signal from the digitizer to a computer and perform computation...
Steganography is the science of hiding information in such a way that an adversary wouldn't know it existed. As a result of research in this field, there are now many practical steganography tools for mediums that aren't processed in real time. However, research on real time mediums, for example Voice over Internet Protocol (VoIP), isn't as mature. While significant and ever-improving research has...
A design pattern addressing the versioning problems of multi-generational software systems is presented. The problem of coordinated versioning, inheritance, and evolution are considered. A model is proposed for evaluating the pattern. Preliminary results suggest high scalability and effectiveness.
This paper introduces a novel visualization approach for the Smart Power Grid using advanced scientific visualization software AVS Express 7.3, to explore the planning and monitoring of the American Electricity Infrastructure. The paper discusses the rationale underlying the Power Grid design, describes its implementation and performance details, and assesses its strengths and weaknesses against the...
Load shedding is required when there is an imbalance between electricity demand (customers' usage) and electricity supply (the ability of the electricity network to generate and transport the required amount of electricity to meet this demand). Hybrid novel design methodology is proposed to enhance the underfrequency load shedding in terms of consumer satisfaction level. A Consumer Priority Assignment...
