The intelligent home appliance monitoring is the mainstream development of the future automation and networking technology. Appliance operation can be easily monitored through sensing and other similar perceptions of the corresponding power link. These products of smart energy monitoring system communicate with one another via intelligent sockets equipped with ZigBee wireless transceivers. A home-based...
Documenting a preliminary pilot study of the quantification of the reliability of recyclable elements and sub-assemblies in a precast concrete structure, this paper explores the feasibility of applying a most recently developed expectation-maximization (EM) algorithm embedded safety assessment technique. The recent push to increase sustainable practices in the construction industry can be attended...
Conference proceedings front matter may contain various advertisements, welcome messages, committee or program information, and other miscellaneous conference information. This may in some cases also include the cover art, table of contents, copyright statements, title-page or half title-pages, blank pages, venue maps or other general information relating to the conference that was part of the original...
A switching strategy for multi-level multi-phase voltage source inverter (VSI) based on optimal feedback quantization is derived. The contributions include the improved harmonics distortion comparing with the conventional SVPWM and the realizable block diagram of quantization to produce optimal switching state. By finding the most significant switching state, the implementation of quantization block...
A new dual-stator brushless doubly-fed induction motor is proposed for EV/HEV applications. With the advantages of high torque density, wide torque-speed range, synchronous motor-like characteristics, robust rotor configuration and low cost as a result of no permanent magnets, the proposed configuration exhibits promising potential as a traction motor in EV/HEV. The possible topology, rotor winding...
Since the Great East Japan Earthquake, everyone has come to relook how to use electric energy. In addition, people who say that it should aggressively install safe and clean energy system have increased. To create city which is learned from nature, supported by science and technology, we started activity of community in Fukuoka and Yokohama. This paper introduces overview of smart energy system and...
This paper presents an integrated modulation scheme based on the chaos theory, which is implemented on the bidirectional power interface for vehicle-to-grid (V2G) systems. The energy is frequently exchanged between the electric vehicle (EV) and the power grid in V2G systems, where the conventional power electronic conversion technique is evitable to increase the complexity of the electromagnetic environment...
Design strategies that account for local micro-climatic conditions can reduce the overall energy consumption of buildings over its life. This paper evaluates non-structural retrofit strategies for reducing energy consumption for existing buildings. Based on real-life data on usage statistics of buildings and accounting for local climatic conditions, we validate energy consumption predictions by Sefaira®...
The objective of the proposed method is to reconstruct the three-dimensional structure of a scene in real-time via moving a low-cost RGB mono-camera by hand. Only simple and fast algorithms are used for the purpose of real-time with a decent structure resolution. To compensate the defects of the cheap algorithms, the scene structures will be buffered and used only when they are considered as a good...
This paper represents a comparative picture of irrigation cost of different Bangladeshi crops for diesel, grid electricity and solar power based irrigation systems. The study has been conducted on 27 types of crops. All the data were collected about volume of water for those crops. Then three different types of pump (solar, diesel, electric) have been chosen with same power rating i.e. 5hp. Specific...
In recent years, machine-to-machine (M2M) networks have been widely considered in wireless communication systems. Machines typically have constrained power, and their processing and communication capabilities are limited. To avoid the transmission of redundant information in order to save the transmission power, compressive sensing (CS) is a promising tool to consider. In this paper, under the two-tier...
Since the government data is credible, plentiful, and relevant to citizen, the government disclosures part of its data as government open data to stimulate the development of public applications [1]. The trip planning application providing as the best path for the trip [2] draws the most attention for people. In this article, we proposed a real-time trip planner system assisted with government open...
The navigation within the building is possible to display using the oriented graph. To find shortest way in the graph is possible to solve in the different mode. Our question is Is possible to predict the shortest way by artificial Intelligence, primarily by Perceptron neural network with one secret layer. During the test project was used algorithm Dijkstra [1] and was developed tool for automatic...
Employing an L-C-L filter cell to modify the asymmetrical half-bridge converter (AHBC), an AHBC with input current ripple reduction (AHBC-CRR) is proposed. In addition to having zero-voltage switching operation, low voltage stress, lossless snubbing, and voltage clamping features preserved from its predecessor, the proposed converter can shape input current waveform of AHBC to a non-pulsating fashion...
In the university environment, as well as in many other institutions and industrial companies there are a large number of different assets. Significant differences from other enterprises or institutions are the large variation in purchase and huge turnover of assets. Exceptionally assets are lent or transferred between faculties, relatively frequent are exchanges and long-term loans between departments...
The integration of small sized standalone solar systems to the grid is technically complicated resulting into expensive operation which is not affordable to all. As such, this paper presents a smart controller based design using digital signal processing for cost effective operation of solar-grid tied system. The hybrid system is able to size the connected system and deploy the operation strategy...
In this paper, the bidirectional three-phase dual-active-bridge DC converter with the hybrid modulation is implemented, to improve the light-load efficiency. Charging and discharging behaviors are controlled by the phase angle and the duty cycle of voltage applied on both sides of the transformer. The hybrid modulation and the experimental results of the converter are presented. A lab-scaled converter...
A climate change simulation framework for intelligent green building adaptation design is proposed. The simulation framework is developed for studying environmental performance of existing or proposed green buildings under present and future urban microclimate conditions. It draws on a synthesis of environmental computer simulation in three areas: (1) overall climate change scenario modelling at city...
This paper introduces a method to cooperatively operate the chemical-free energy storage system (ESS) with the solar photovoltaic (PV) system for more resilient power distribution in buildings. Specifically, the power distribution network in a commercial building located in Singapore is investigated as a case study. The re-design of building power distribution network and the ESS operation strategy...
In this paper, a green communication scheme is proposed for a cooperative network wherein two source nodes send data packets to a destination node with the aid of a relay node. There is a trade-off between the time taken and the energy consumed by the system to complete the transmission of the data packets. A mathematical analysis on the expected cost in time and energy by the system are derived....
