Here we used an alcohol sensor circuit along with LCD display, a buzzer alarm, ATmega328 microcontroller, keypad and GSM sim module. The system first uses the alcohol sensor in order to detect the alcohol. The sensor provides analog input. These analog inputs are sent to the microcontroller for further processing. The microcontroller calculates the percentage of alcohol from the analog input received and displays the same on the LCD screen. The device was observed to sound an alarm when the percentage of alcohol exceeded the preset value of 0.05 g/mL. Through the use of a 4x4 keypad, documentation of the driver license serial number, the car plate number and name of the driver was achieved. These documented details of the erring driver were transmitted to a preprogrammed mobile phone number via SMS using the SIM800 GSM/GPRS module.</p> B. I. Bakare A. Umoru S.

It consists of temperature sensors for real-time temperature monitoring, ESP32 Thing board is used for data receiving, processing and sending it to the MQTT broker, openHAB software installed in the personal computer is used as a home server for creating dashboard panel, MQTT broker is used to establishing the communication in between openHAB home server and ESP32 Thing board, Wi-Fi router is used to create the communication channel, a battery-powered remote-controlled heater with a digital thermostat is used as a testing device where user can set the desired temperature for house heating. The main objectives of this work are to design a low-cost monitoring and control system for thermal energy storage systems, to monitor the real-time temperature data, to design a control system for thermostat settings with the following features such as manual/automatic operations, local/remote control options. The user can access the dashboards locally via any computer and remotely via openHAB Cloud console from anywhere in the world. The proposed system in this work will help residence to manage their heating systems smartly in a cost-effective way, which will be the replacement of the conventional thermostat settings. The utility provider company can also use this system to control the thermostat settings from centrally, wirelessly, and remotely.</p> Md Habibur Rahaman M.

The amount of stored data and query data sources have become needful features for huge data systems. There are a large number of platforms used to handle the NoSQL database model such as: Spark, H<sub>2</sub>O and Hadoop HDFS / MapReduce, which are suitable for controlling and managing the amount of big data. Developers of different applications impose data stores on difficult tasks by interacting with mixed data models through different APIs and queries. In this paper, a complex SQL Query and NoSQL (CQNS) framework that acts as an interpreter sends complex queries received from any data store to its corresponding executable engine called CQNS. The proposed framework supports application queries and database transformation at the same time, which in turn speeds up the process. Moreover, CQNS handles many NoSQL databases like MongoDB and Cassandra. This paper provides a spark framework that can handle SQL and NoSQL databases. This work also examines the importance of MongoDB block sharding and composition. Cassandra database deals with two types of sections vertex and edge Portioning. The four scenarios criteria datasets are used to evaluate the proposed CQNS to query the various NOSQL databases in terms of optimization performance and timing of query execution. The results show that among the comparative system, CQNS achieves optimum latency and productivity in less time.</span></p> Eman A. Khashan Ali I. El Desouky Sally M.

This manuscript describes the control design to achieve a deadbeat desirable performance in terms of: i) Zero steady-state error. ii) Minimum rise time. iii) Minimum settling time. iv) Less than 2% overshoot/undershoot. This paper considers an Islanded microgrid system composed of two distributed generation (DG) units. Each DG unit includes three-phase pulse width modulation (PWM) inverter. The proposed controllers are proportional- integral (PI) type. The Controllers gains of the inverters and the Phase Locked Loop (PLL) parameters are designed to guarantee deadbeat dynamic performance in terms of minimal overshoot and system stability. The Particle Swarm Optimization (PSO) is used to tune the controller parameters of the current, PQ loops, and the PLL. The proposed controllers are compared with the traditional (Ziegler and Nichols), auto-tuned, and interior-point methods to shows the excellence of the proposed technique. Results authenticate and endorse the effectiveness of the proposed controllers and PLL design technique to achieve the desired deadbeat response of the study microgrid system.</p> Ehab Bayoumi Mostafa Soliman Hisham Soliman Copyright (c) 2020 Ehab Bayoumi, Mostafa Soliman, Hisham Soliman 2020-09-23 2020-09-23 4 5 10.24018/ejece.2020.4.5.242 Optimal Reconfiguration of Distribution Network in Presence of D-STATCOM and Photovoltaic Array using a Metaheuristic Algorithm <p>In this paper, grasshopper optimization algorithm (GOA) a novel meta-heuristic optimization algorithm is used to solve the network reconfiguration problem in presence of distribution static compensator (D-STATCOM) and photovoltaic (PV) arrays in a distribution system. Here, D-STATCOM acts as distribution flexible ac transmission (D-FACT) device and PV arrays as decentralized or distributed generation (DG). The main purpose of the present research includes power loss minimization and voltage profile (VP) enhancement in radial distribution systems under different loading conditions. The proposed GOA is based on swarming behavior of grasshoppers in nature. The proposed GOA is validated using the standard 33, 69 and 118 – bus test systems. The simulation results proved that the optimal network reconfiguration in presence of D-STATCOM units and PV arrays leads to significant reduction in power loss and enhancement in VP. The results obtained by the proposed GOA are compared with base value and found that the optimal network reconfiguration in presence of D-STATCOM and PV arrays is more beneficial than individual objective optimization. Also, the proposed GOA is more accurate, efficient and reliable in finding optimal solution when compared to existing modified flower pollination algorithm (MFPA), firework algorithm (FWA), fuzzy-based ant colony optimization (ACO) and genetic algorithm (GA).</p> Kola Sampangi Sambaiah T.
