The fabrication of a human head phantom for the use in microwave systems designed for head imaging is presented. Since most of the ongoing research activities on microwave imaging of human head use the band from 1 GHz to 4 GHz, the fabricated phantom is designed to emulate the electrical properties of human brain tissues across that band. A material that has electrical properties equal to those of...
Mind is a compound information handling and processing mechanism and consciousness — (the processed information) is the core component of mind. The spirit of consciousness is definite correspondence between substance with some rules or laws. Information processed in the mind approaching from both the outer world (physical world) and the inner world (mind). The information can be represented in many...
Shared services is an organizational culture of sharing and innovation across the organization. It enables the sharing of services by functions of organization such as Finance, Human Resources and Information Technology through a common mechanism of a shared services centre. Delivery of services is through Information and Communication Technology infrastructure. Shared services increases productivity...
Potential functions can be used to design efficient path planning schemes. However, it is often difficult to design appropriate potential functions to mimic desired behavior of the agent. Instead of using a pre-designed potential function for path planning, this paper presents an algorithm that learns the underlying potential function from a given sample trajectory generated by a “expert” (say, a...
Speech dialogue systems, such as Apple's “Siri,” have gradually become more widespread, and in the near future, a greater number of general users will have the opportunity to communicate with such systems. To facilitate this, it is necessary for the system to communicate more naturally with users, and to realize that both verbal and nonverbal information must be taken into consideration. Therefore,...
Recently, personal robots and home robots are developing by many companies and research groups. It is considered that a general effective interface for user of those robots is speech or voice. In voice instruction system, we propose the estimation method of a target. The present method is based on the instruction history of a user. Additionally, we propose the update algorithm of fuzzy rules based...
Many robots are designed so that the number of their actuators is as small as possible to decrease their weight. In many cases, the number of actuators in robots is smaller than that of muscles in animals. We propose the method to increase the dexterity of the robot without increase of actuators. The link made from shape memory gel (SMG) is deformed to be suitable for each task of the robot. The methods...
Striatum is a major stage of the motor loop but, despite a pivotal role in the execution of movements, it has been poorly studied thus far under Parkinsonian conditions and Deep Brain Stimulation (DBS). We propose a computational framework to analyze the spiking activity of striatal neurons under several conditions. This framework combines point process models and single unit recordings, and separately...
Expressing emotion to others and recognizing emotion state of the counterpart are not difficult for human. Emotion state of a person may be recognized from the facial expression, voice, and/or gesture. Speech emotion recognition research gained a lot of attention in recent years. One of the important subjects in speech emotion recognition research is the feature selection. The speech features used...
This paper presents a method of automatic lexical stress assessment for L2 English speech. Syllable stress can be labeled at three levels - primary (P), secondary (S) and no (N) stress, but secondary stress may vary among word pronunciations within and across accents and present difficulties for human perception. Hence, evaluation of lexical stress based on all three levels (i.e., the P-S-N criterion...
Synthesis of natural sounding speech is the greatest challenge in a Text-to-Speech Synthesis (TTS) system. In natural speech, duration, intensity and pitch are dynamically varied which is manifested as rhythm or prosody of speech. If these variations are not recreated, the synthesized speech will sound robotic. Synthesis of good quality speech depends on how well the duration and intonation patterns...
In contrast to intelligence, wisdom is the part of the propositional knowledge part of the background of knowledge that is a mean between two extremes of believing without sufficient evidence and not believing with sufficient evidence. Wisdom may be incorporated in an artificial intelligence system as artificial wisdom (AW). An intelligence system with AW, will learn a collection of activities like...
In this article, we discuss how to detect occasional social interaction by a group of people in an open space such as a hall by observing the environment by cameras. Since it is known in the field of social psychology that some characteristic arrangement is maintained by each group of people during interaction, previous works have tried to detect social interaction based on the arrangement. However,...
This study focuses on the negotiation in the financial markets, specifically in programming an algorithm to trade automatically (without human intervention) in the foreign exchange market (Forex). The platform used in this study was the Meta Trader (version 5), which allows for this kind of negotiation. The main objective was to conclude about the effectiveness of anewly developed strategy for automatic...
In this paper, we discuss the causes and implications of fratricide in a battlespace increasingly governed by information and intelligence. We propose that, by integrating artificial intention awareness into battlefield communication and control systems by means of the Digital Crosstalk client-server architecture, we can address many of the problems that have been found to be causative agents in fratricide...
The security of web applications is an ongoing dilemma. Hackers and bots are getting more and more innovative in bypassing the various defensive tools implemented to enforce security. e-Commerce Applications, such as those used for the transaction processes, could be in a placed in a position of not providing a fair chance to all consumers because because can interact more quickly. This is especially...
Foreground extraction and moving object detection are often used in human tracking systems. However those methods are not able to produce accurate results when objects are too close or when occlusions happen since the result is generally a single big blob which contains all the different objects. In this paper we propose a novel and efficient moving object detection enhancement method. Indeed, by...
Customer store loyalty is one of the most important motivations that facilitate the intentions of re-patronizing a retailer's website and create marketing values for firms. Research on survey-based for measuring consumers' loyalty to persist in online shopping environment has been developed. But while the measured values of human perceptions towards various attributes are often uncertain data, most...
In this work, a human head from nuclear electromagnetic pulse (NEMP) is simulated by using CST program for the analysis of SAR at 1MHz, 10MHz, 50MHz. The human head model is homogeneous and simulated with the brain equivalent material. And the NEMP is described by the second double exponential pulse shape with some characteristic parameters. From these results, we find that while the frequency increase,...
