The objective of this work is to study and design a solar inverter, of a power of exit of environ 500 VA with a tension of entry of 12 VDC and an exit has purely sinusoidal wave of 230 VAC at a frequency of 50 Hz. The improvements made to the inverter are primarily at the level of the order, with first of all, the generation of a purely sinusoidal wave, but also the monitoring of the tension of entry...
This paper describes the development of Flutter, a new sensor-driven, robotics technology kit for in-school use with elementary-age students. Our development began by conducting focus groups with teachers (N=6) in which we guided a participatory design process. Through affinity diagramming, we identified science and math as areas of focus for the program; we also brainstormed project-topics with the...
This paper presents the system that allows SEFI modelling by means of injecting upsets in different microcontroller memory blocks, carrying out its functional control and detect the moment when SEFI occurs. Test setup was developed on the basis of National Instruments PXI modular equipment and LabVIEW software. Developed fault injection system was tested on PIC17 microcontroller. The comparison between...
Post Silicon Validation is critical step in order to deliver quality microcontroller chips to customers but is increasingly becoming complex and time consuming process as the design size is increasing. Due to increased number & diversity of design intellectual property, microcontroller post silicon validation has moved towards customized validation concept and hardware setup for individual design...
The Internet-of-Things (IoT) is an new area where everyday objects are embedded with intelligence and the ability to transmit and receive information. The arrival of this emerging topic presents a pressing educational need. In this paper, a new, innovative course on IoT is presented. The pedagogical approach is to guide students in developing a conceptual “toolbox” of necessary IoT skills centered...
In most homes, electrical appliances are controlled and operated manually, this could be difficult and challenging to do when tiredness, handicap, morphological variations (height, aging etc.) and inadequate skill stands in the way as impediment. This study aims to implement a better and more flexible means of controlling home appliances by means of an automated switching mechanism using speech recognition...
Vehicle accidents are one of the most leading causes of fatality. The time between an accident occurrence and the emergency medical personnel are dispatched to the location of accident is the critical factor in the survival rate after an accident. By minimizing the gap time, mortality rate can be reduced. One approach to reduce the delay time is to use the Real Time Wireless Accident Tracker Using...
This paper presents a design approach to an embedded monitoring system found in distributed renewable energy power systems. The grid connected distributed power system, delivers energy to the consumers located on the micro-grid, operating at distribution voltage levels, and also delivering the remaining surplus energy to the main distribution grid. The aim of this paper is to present the development...
This paper presents a way of creating a laboratory work on controlling a remote servomotor. Using LabView, a real experiment is performed, the equipment being remotely controlled, and viewing with a camcorder. The purpose of this paper is to demonstrate the possibility of carrying out laboratory works for students requesting e-learning.
Surveillance is one of the most important security system in today's life as it protects home from theft, burglaries and murders, as become routine in big cities. This system is very useful as it is used in many places like offices, industrial, storehouse or bank locker room, ATM etc. This embedded based home security system designed by use of smart sensors like pyroelectric infrared sensor (PIR),...
This paper presents a design of a remotely placed village school where smart education can be provided to kids. Automatic pre-programmed story based animated lessons are taught in the class from computer screen for an efficient and unique learning. Schools are powered by locally generated green renewable electricity from solar PV modules. Microcontroller based regulated DC bus is efficiently used...
The diagnostic information and the prescription of any health discrepancies are generated by checking certain parameters with an expert verified medical database. The health parameters are taken as input via sensors or through the keyboard. The microcontroller based intelligent system is designed with the help of medical data base.
IOT is one of the most controversial topic in current digitalized era. The scope of IOT is developing gradually with new technologies like smart grids, smart homes, smart cities etc. IOT permits internet connectivity for all kind of physical objects and devices. Virtualization of different types of system is becoming trend in today's world that allows to perform without direct physical interaction...
The paper considers the results of MATLAB modeling of artificial neural networks trained to perform basic logical operations: AND, OR, XOR and NOT. Below is a description of implementation of these artificial neural networks on a microcontroller by Texas Instruments family MSP430G2x, which is marketed by the manufacturer as an ultra-low power consumption device. Implementation of artificial neural...
The currently used hardware validation architectures for Application Specific Integrated Circuits intended for automotive Engine Control Unit development are reviewed and a new architecture is proposed. An alternative to hardware validation by different simulation architectures is proposed and analyzed.
The evolving in Internet of Things and the plenty diversity of electronic components bring challenges and demand high level tools to improve the application development process. Concurrent computing is useful for catching the logic structure of a problem or solution and handling different and independent components, which is convenient in this context. Therefore, in this paper is presented a library...
The method used in Romania for combating hail is the sowing of the clouds method, with missiles launched from the ground. This paper presents contributions of the University of Craiova, Center for Innovation and Technology Transfer in the development Hail Suppression System.
In this paper, we present experimental results of photovoltaic (PV) emulator systems implemented in a low-cost microcontroller. The insufficiency of space for installation of real PV panels and the high costs of the commercial emulators require of alternative systems which allow the generation of the characteristic curves of the solar panels. Irradiance and temperature can be set on the emulator to...
Olfactometers are kind of machines specially designed to deliver different odorants to the users, based on a timely protocol. Purchasing off the shelf systems are expensive and require additional customizations according to the type of the experiments they will be used for. In order to facilitate smell, taste, psychology, and neuroscience experiments we have developed our own laboratory olfactometer...
This paper proposes and analyzes the use of the Arduino Zero board as the lab platform for the Computer Structure course that constitutes an essential part of Computer Science studies. The understanding of the main functional blocks of a computer, addressing the main concepts included in the course syllabus, is reinforced by mean of the hands-on experience acquired in the lab sessions and the completion...
