The architecture of a software-driven testbed is discussed. The test setup has been developed as measurement and instrumentation system to functionally verify and thermally validate the communication subsystems designed and manufactured for the nanosatellite applications. The system is applied for qualification of a communications subsystem currently under consideration for ZA-CUBE-2 mission.
One of the objectives of this research is to explore and investigate on how to improve online voice communication. We use our previously developed user-specific emotion recognition model to recognize user's emotion during communication and then to express it using an avatar to show to the partner. Another objective is to investigate the performance of our model in real-time environment using a stand-alone...
For mobile phone users, short message service (SMS) is the most commonly used text-based communication type on mobile devices. Users can interact with other users and services via SMS. For example, users can send private messages, use information services, apply for a job advertisement, conduct bank transactions, and so on. Users should be very careful when using SMS. During the sending of SMS, the...
Introducing more Distributed Generation (DG) into power grid infrastructure drives more attention to understand how large scale DG affects grid operation. Islanding is an important concern in this area. Islanding refers to the condition that DGs within a microgrid continue energizing while the microgrid has been disconnected from the main grid. Considering the adverse effects of Islanding, it should...
This work is motivated by the need for the fundamental increase of spectral efficiency with the transmissions on the Transmission Control Protocol and the Internet Protocol (TCP/IP). We define a bit-unit (BU) that is conceptually similar to an IP packet that contains sufficient information for its destination to identify the address and interpret the contents. Armed with these functions, each BU is...
Micro-grid is defined as a local power network with distributed energy resources (DERs) as micro-power sources scattered throughout the supply area. For reliable and short range transmission of power, micro-power sources are controlled as standalone as well as grid-synchronized power sources. The idea is to design a resilient, efficient and cost effective infrastructure based on advanced communication...
OFDM (Orthogonal Frequency-Division Multiplexing) is one of the most used digital schemes at the moment. Conventionaly, OFDM uses inverse Fast Fourier transforms and Fast Fourier Transforms (IFFT/FFT) at the transmitter and receiver to modulate and demodulate data. This work analyses different alternatives to the use of these IFFT/FFT of OFDM systems by replacing them with Discrete Cosine Transform...
This paper reviews the Internet of Things in an automotive setting, complemented by Electromagnetic Interference as a cause of failures. Electromagnetic Interference is, as a common cause failure, able to disturb even redundant systems. Due to the safety-critical nature of automotive applications, different methods in order to reduce the susceptibility and to increase the robustness of automotive...
The uprising interest in multi-agent based networked system, and the numerous number of applications in the distributed control of the smart grid leads us to address the problem of time synchronization in the smart grid. Utility companies look for new packet based time synchronization solutions with Global Positioning System (GPS) level accuracies beyond traditional packet methods such as Network...
With the modernization and commercialization of the unmanned aerial vehicle (UAV) industry, new unmanned aircraft system (UAS) designs are being researched and developed for a variety of applications in the civil market. This project is for a vertical take-off/landing (VTOL) UAV which is being developed for new and cost-effective agricultural solutions. The proposed design entails setting up a new...
Carbon monoxide (CO) concentration reflects the environmental quality of an area. An instrument that measures CO level is very useful for mitigation of effects caused by it due to industrial development. The inherent problem of CO measurement is wide distribution of this gas that continuous measurement is difficult to do. This research proposes a CO measurement system using wireless sensor. The system...
Information sharing in teams is one of the most important aspects of successful software development. For instance, requirements, design decisions and guidelines need to be communicated with the whole team or with specific team members. For information exchange, communication is mandatory. Meetings are an effective way to communicate with many team members. Hence, much information can be shared during...
This study investigates how genetic programs can be effectively used in a multi-agent system to allow agents to learn to communicate. Using the pursuit domain and a co-operative learning strategy, communication protocols are compared as multiple predator agents learn the meaning of commands in order to achieve their common goal of first finding and then tracking prey. The outcome of this study reveals...
This paper discusses on-going research in the ways Global Software Engineering (GSE) teams collaborate for a range of software development tasks. The paper focuses on providing the means for observing and understanding GSE team member collaboration including team coordination and member communication. Initially the paper provides the background on social and human issues relating to GSE collaboration...
This paper represents a cooperative searching strategy of swarm robot in finding and localizing odor source. 3 robots, namely: Cyborg G11, Cyborg G12, and Cyborg G13 were used as agents that form the swarm in this research. The cooperation among the robots trough communication has shown the success of the swarm in odor searching. When one of the agents in swarm robot detected a high concentration...
According to the craft flow and requirements, the automatic control system was designed by ourselves for the high-temperature and high-pressure reaction tank. As system hardware core, industrial computer, PLC (Programmable Logic Controller) and serial communication technologies were applied in hardware design. Signal collection and converting, data converting and process control were realized by software...
The article focuses on experimental measurement of multi-carrier narrowband Power Line Communication. The aim of experimental measurements was comparison of multi-carrier narrowband Power Line Communication from the view-point of possible communication distance, available data rate and impact of noise. The specifications G3-PLC and PRIME are considered. The field test results and data rate measurements...
With the increase in awareness about climate change, scientists and engineers are emphasizing on the energy production through renewable energy sources, thus giving rise to the distributed generation and smart grids. The expected growth in distributed generation is causing issues related to power quality and efficient operation of the overall power system. Under the given circumstances, smart grid...
This paper explains how Fusion networking technology can be used as a communication mechanism between utility substations for transporting time critical traffic in wide area power system protection applications to attain deterministic low delay, zero packet loss and ultra-low packet delay variation. The requirements for inter substation communications are presented with focus on the IEC 61850 protocols...
In this research, a multiple regression analysis was employed to analyze the correlation between the measured personality and expressivity or decipherer ability. Analysis was performed to determine what kind of personality factors are related to decipherer ability. As a result, it is clarified that decipherer ability have strong relationships with self-assertion, diligence, openness, and acceptance...
