The study of brain dominance in human-computer interaction has increased in recent years in an attempt to address the need of users especially who cannot read or write. The objective of this paper is to determine the brain dominance from brainwave signal that are measured using Emotive device and to analyse the pattern of brain dominance brainwave signal by using signal processing. The result of Power...
In this paper, we proposed a novel method (CompUXLSA) to predict user experience from reviews sentences using Latent Semantic Analysis (LSA). Human uses words to represent or express thoughts. The “word of mouth” could influence others especially through web and social media, which are the common communication tools today. We believe that reviews can be categorized according to user experiences since...
A previous study proposed a driver-assistance system (DAS) using a haptic interface to encourage drivers to prepare for spontaneous deceleration behavior against potential collision risk. Driving simulator experiments showed that drivers’ reaction time were shortened while using the haptic DAS. However, there existed concerns regarding drivers’ risk compensation behavior while using the system. Therefore,...
The basic algorithm that consistently updates the switches of a Software Defined Network while preserving the update property of per-packet consistency is the two-phase update. The two-phase update is underspecified on two matters: 1) how to detect when the last packet of the old rule set has left the network and therefore exactly when to delete the old rules 2) recoverability of the update. Recoverability...
This paper presents an optimized configuration of a bidirectional single-phase vehicle to grid (V2G) system which consisted of a DC/AC inverter and a full-bridge isolated DC/DC converter. An optimized current controller is designed for the DC/AC converter that improves the system operation in terms of reducing switching losses whereby increasing the efficiency of power-flow. It regulates the DC-link...
Software-Defined Network (SDN) is an emerging network paradigm which enables flexible network management by separating control plane from data plane. Due to the centralized management scheme that SDN adopts, intensive control plane overhead incurs as the scale of SDN increases. One way of alleviating the overhead is to either distribute the overhead to multiple controllers, or offload the overhead...
In this demo, we provide a Mininet-based Software-Defined Network (SDN) simulation environment that improves the total flow throughput and scalability of the overall network. Mininet is a suitable and manageable tool to implement the proposed SDN based flow admission control module in order to configure the entire topology since it has already built in Open-Flow switches and virtual controllers. This...
Distributed renewable energy has become a significant contender in the supply of power in the distribution network in Queensland and throughout the world. As the cost of battery storage falls, distribution utilities turn their attention to the impacts of battery storage and other storage technologies on the low voltage (LV) network. With access to detailed residential energy usage data, Energex's...
The main objective of this research was to investigate the association between electroencephalogram (EEG) and memory recall in human participant. A sample of 34 healthy participants was recruited and exposed to 10 minutes animated learning contents. After 30 minutes of the learning session, they performed a memory recall task; the correct and incorrect responses in recall task were recorded for computing...
Reversible logic is one of the emerging computational methodologies which assures zero power dissipation through theoretical laws of thermodynamics. It has received significant interest in application on quantum computing, nanotechnologies and low power computing devices. In this work, we present a reversible logic implementation for Binary Coded Decimal (BCD) adder which is designed to obtain lowest...
Arabic phonemes can be categorized as voiced and voiceless with each phoneme has a different articulation manner according to the corresponding vowel. In addition, Arabic language comprises of six vowels. Hence, in this paper, a comparison within each vowel between the voiced and voiceless Arabic phonemes is conducted. The experiments are based on Malay speakers. In total, 1433 tokens are recorded...
Managing coordination between Autonomic Managers in the Multi-Cloud environment requires an effective control mechanism to handle issues such as conflict during decision-making and in the execution phase. MAPE-K control loop provides a primary control loop in managing adaptation activity where the complex environment especially in Multi-Cloud with decentralized Autonomic Managers, is not sufficient...
Noise affects the values of pixels in a thermal image. As the values of pixels will determine the appearance of the bit planes of thermal images, noise will affect the bit planes as well. Noisy thermal images have bit planes which resembles static. These bit planes will not be useful for the purpose of extracting low-level details, e.g. detecting edges and blobs. The method described in this article...
The emerging gigabyte fast access to customer terminal (G.fast) project has been initiated within ITU Telecommunication Standardization Sector (ITU-T) SG15 in February 2011. This new copper access technology is expected to provide aggregate (upstream and downstream) data rates up to 1 Gbps over distances up to 250m. This paper discusses the concept of G.fast channel modelling based on copper cable...
In this paper, theoretical analysis on the downlink spectral efficiency of non-orthogonal multiple access (NOMA) in Nakagami fading is introduced. Thanks to our accurate analytical technique, a closed-form expression of NOMA is proposed. With the closed form, the exact average of the spectral efficiency can be achieved at different user power allocations and channel conditions. Furthermore, the findings...
Differential evolution (DE), one of the evolutionary algorithms (EAs), is well-known for its quality solutions and speed convergence. Just like any EA, the execution of DE depends on the selection of its control parameters consisting of population size, crossover rate and scale factor. DE is operated by two different kinds of search mechanisms, i.e., exploration and exploitation. The selection of...
Decentralized energy generation and distribution systems (mini/micro-grids) based on renewable energy sources forms one of the prospective solution for electrification of remote areas where conventional grid penetration is non-feasible. In such scenarios, efficient operation and periodic maintenance becomes indispensable for system sustainability. Deploying these systems in geographically inaccessible...
This paper addresses the L1-optimization concept advanced in the modern control theory with an application to the design of the L1-optimal lateral autopilot system. The control objective is to maintain the desired roll orientation of an UAV in the presence of external unmeasurable disturbances, in particular, of a gust. To achieve a high performance index, the two separate control algorithms are proposed...
The article deals with the problem of controlling the flow of information coming from a group of unmanned aerial vehicles by radio channel. The stream is a sequence of binary information packages. The inevitable data losses compensated by repetition of lost packages. Modern methods control of data flow assumes using a mechanism automatic repetition query based on the method of sliding window. In this...
