The use of digital games in education is already a reality, but their use in this area has been hampered by the lack of consolidated resources for evaluation of game-based learning. This paper reports a computational architecture for learning analytics in game-based learning that is based on relational analysis and data mining of data containing evidences of learning collected during the game play...
Dialogue systems are computer systems that communicate with a human in spoken or written form. Their popularity has increased in recent years and they attract a large research and development interest. In this paper, a survey on dialogue systems is presented. A classification scheme is proposed and then the reviewed methodologies are evaluated based on a number of features, in order to obtain a maturity...
E-Learning is widely accepted to be the next generation of learning approach with extended features, while technology and theory step forward. However, the current model of e-Learning system lacks the scalable and sustainable infrastructure to support extended features. In this paper, we discuss the technical challenges faced in e-Learning and some common problems concerned by content providers. After...
In this paper, we discuss a classification method of nursing-care texts using the word2vec [1]. The word2vec is a tool which provides the continuous bag-of-words and skip-gram implementations for realizing word vectors. We have tackled to classify nursing-care texts, which are freestyle Japanese texts, for improving nursing quality in several years. Several machine learning methods have been used...
The modular multilevel converter (MMC) has become an attractive option for dc/ac conversion in many power system applications, in particular for HVDC transmission. Due to its parallel arrangement of phase legs the MMC is known to be a wye configured architecture. In this paper, the equivalent delta formulation of the conventional wye architecture is introduced. The delta configured MMC, enabled by...
Memetic Multi-Agent System (MeMAS) has recently emerged as a combination of memetic automaton and multi-agent system (MAS), wherein all meme-inspired agents acquire increasing learning capacity and intelligence through meme evolution. This paper further presents a study of MeMAS in developing human-like non-player characters in complex first-person shooter (FPS) games. In particular, we consider a...
Linear spectral unmixing consists on the identification of spectrally pure constituents, called endmembers and their corresponding proportions or abundances using a linear model. Traditionally, most of the attention has been focussed on the exploitation of spectral information when identifying a set of endmembers and, only recently, some techniques try to take advantage of complementary information...
In this paper we present an implementation of and a proposed algorithm for an easily expandable hardware Artificial Neural Network (ANN) capable of learning using inexpensive, off-the-shelf microprocessors. While significant work has been done in hardware ANN implementations, this research offers a unique, general use, unspecialized, and inexpensive model with a flexible architecture representation...
For the recent advances of Cloud Computing technologies, cloud applications have been popularity for their rich set of features. Therefore, their practical use for promoting business values can be expected. As such, cloud applications are recognized as a trend for the next generation of existing Web applications, and hence how to migrate these Web applications to the clouds becomes a desired field...
The advantages of avionics switched network in network scale and flexibility greatly improve the communication performance of avionics network, promote the development of IMA/DIMA technology and also increase network scale and complexity. Meanwhile, requirements for the management of the avionics system are also on the rise. In this paper, the characteristics of SNMP protocol and airborne switched...
This paper presents the design, deployment, and initial testing of an agent-based test bed to support a wide range of experiments and demonstrations of advanced control of building systems for energy efficiency, occupant comfort, and reliable interaction with the electric power grid. The test bed possesses the following major characteristics: 1) it supports interactions among heterogeneous components...
Binary Exchange Algorithm (BEA) always introduces excessive shuffle operations when mapping FFTs on vector SIMD DSPs. This can greatly restrict the overall performance. We propose a novel mod (2P-1) shuffle function and Mod-BEA algorithm (MBEA), which can halve the shuffle operation count and unify the shuffle mode. Such unified shuffle mode inspires us to propose a set of novel mod (2P-1) shuffle...
Considering the technical advances and economicadvantages of integrated architectures and cloud computing we conjecture that the realization of a real-time cloud, called a fog that provides reliable electronic services with temporalguarantees on board a vehicle efficiently and flexibly will be thelogical next step in the development of an automotive electronic architecture. In this paper we introduce...
There is a huge discrepancy between off-the-shelf (COTS) hardware architectures and requirements for embedded industrial applications. Industrial systems are getting more complex by the day, and an interaction of highly diverse components within these systems is unavoidable. An implementation of such systems on COTS hardware is challenging. Platforms based on single-core CPUs is becoming limited,...
This work presents improvements in terms of computational efficiency of a cellular automata based virtual environment for ultra-sound propagation, (previously abbreviated as CANAVI, i.e. Cellular Automata for ultra-sound based robot Navigation). Comparisons with our previous implementations using JAVA indicates good speed-up while using low cost, programming environments based on Python and exploiting...
With the rapid development of computer technology, it has been widely used in many fields such as politics, economy, military affairs, culture, and education and so on. The society has entered into the information age with the development of computer and network technologies, however, the security problem of information has become the fundamental mater. As we all know, the basic principle of Von Neumann...
Article describes the architecture design of user authentication system. The key features of architecture is resistance to changes in architectural and infrastructural scopes. That allows to control the functionality of the system and gives possibility to change it without special knowledge and the additional costs, to implement better support for devices from different manufactures. In addition,...
This paper presents the experience from 7 years existence of Faculty of Information Technology at Czech Technical University in Prague with respect to today Computer Engineering specialization trends. Our education process and study methods are based on programmable hardware, embedded systems and design style intended for such devices. All our courses have both parts; theoretical lectures and practical...
Most of the courses should be evaluated time to time in order to determine if the objectives of the degree are keeping reached. In this paper, the steps to update a course of Computer Architecture of the first year of the degree in Telecommunication Technologies Engineering of the University of Vigo (Spain) are described.
In this paper, we investigate computing systems and network architectures, dedicated to high frequency trading applications and evaluate their performances. Both a high processing speed and low network latency are important for high-frequency traders. The financial market literature suggests, however, that extremely high speeds discourage other traders from participating in the market, therefore harming...
