A Unique Method for Detecting and Characterizing Low Probability of Intercept Frequency Hopping Radar Signals by means of the Wigner-Ville Distribution and the Reassigned Smoothed Pseudo Wigner-Ville Distribution
Low probability of intercept radar signals, which are may times difficult to detect and characterize, have as their goal ‘to see but not be seen’. Digital intercept receivers are currently moving away from Fourier-based techniques and toward classical time-frequency techniques for analyzing low probability of intercept radar signals. This paper...
Flexible Boundary Multi-Microgrids Power Distribution Systems with Internet of Thing for System Efficiency Enhancement
Multi-microgrid power distribution systems are gaining attention in the smart grid era. Distributed energy resources, energy storage, as well as energy sharing and scheduling has a great potential to enhance multi-microgrid systems’ performance. This research develops an algorithm for optimal operation of various distributed energy resources in a...
Automatic Generation Control and Automatic Voltage Regulator Design for Load Frequency Control of Interconnected Thermal Power System
This paper presents a new model for each component of Automatic generation control (AGC) and automatic voltage regulator (AVR) loops considering generator rate constraints (GRC) of one and two areas interconnected thermal power system. Any mismatch between system generation and demand results in a change in system frequency that is highly undesired...
Integration of the Internet of things in Service Management: Designing a Monitoring Device for the Elderly
Controlling and monitoring the elderly is an arduous and imperative task with regard to their physical safety. To assist in this aforementioned control, the main objective of this project is to present a real prototype for monitoring the elderly. Therefore, this prototype can become a support tool for managers of nursing homes, hospitals, etc., as ...
Electromagnetic Antenna Cloaking with Metamaterial Structures
Electromagnetic (EM) cloaks, based on spatial transformations, can potentially be utilized as shielding devices for antennas in close proximity with multiple antenna arrangements as well as highly scattering environments. In these environments each antenna can be enclosed in a cloak that is designed to be shield at the transmitting frequencies of t...
A Comparative Study on Fatigue Performance of Die Steel from Variable Manufacturing Routes
In automotive body manufacturing, the dies used for blanking, trimming, and piercing are subject to harsh and demanding conditions, including high-impact loading and a large number of cycles. As the strength of sheet metal continues to increase, the service life of trim dies has become a major concern for the industry. To address this issue, this...
Design, Analysis and Fabrication of Arduino Mini CNC Plotter
This project will demonstrate how to make your own low-cost Arduino Mini CNC Plotter. For X and Y axis we will use stepper motors and rails from two DVD/CD rom microwave steppers and a tee tube you can build a 4x4 printer. Since its a serial communication you can also then use your Bluetooth module to print your stuff or control your printer wir...

Neutron Concentrator, a Hypothetical Small Neutron Star based on the Emission of Neutrons in Minerals Such as Granite and Other Commonly Available Objects
The aim of this work is to verify the existence of neutron emission in some "circuits" mainly composed of common stones. The idea of this work finds its foundation in the moment in which it is possible to limit the scattering of any neutrons produced, once this is done, the neutron beam could be driven so that they are concentrated in a certain poi...
The Ctesiphont system. Evolution of the catenary structure
La complicada situació n de la España de los años de autarquía (1940-55), llevo a que algunos arquitectos propusieran soluciones sumamente económicas y de rápida construcción para tratar de solucionar el grave problema de la falta de vivienda. Entre esas propuestas llama especialmente la atención el sistema Ctesiphonte, basado en una catena...
Time Series Analysis Model For Annual Rainfall Data in Lower Kaduna Catchment Kaduna, Nigeria
Time series analysis and forecasting has become a major tool in many applications in water resources engineering and environmental management fields. The effects of climate change and variability on water demand in the 21st century makes the time series analysis of rainfall, a major replenishing source of water, more imperative than ever before. Th...
