Considering the increase in life expectancy in several countries, including Brazil, and that the average age of digital game players is 31 years, studies and the development of games for adults and senior people as their target audience become necessary. The objective of this paper is to provide the analysis of the impact of the use of Augmented Reality in games with adult users above 45 years. The...
Goal. To create a mathematical tool for assessing the quality of a complex system likely availability (or failure) in the presence of interrelation in the components operation. The tool is different from the Markov's chain and other analogs. Tasks. To introduce a binomial distribution as the sum of the probabilities of ordered subsets of the numbers of successful tests. Introduction to probability...
The purpose of this research is proposing a theory to verify the influence of virtual props trading sites to game loyalty of players. The objects of sampling aims at users who are actually engaged in online games props trading sites. A survey of 459 game players in Taiwan was conducted; research results were generated through the use of descriptive analysis, reliability analysis, correlation analysis,...
In this work, we introduce the Materials Science Conceptual Evaluation (MSCE). This is a 31 item multiple choice test designed to complement the Materials Concept Inventory (MCI) developed in 2002 by Krause et al. In developing this assessment, we collected data from over 700 students, including over 100 interviews, focused on areas where students struggle or have misunderstandings. There are several...
Motion analysis and tracking often relies on multimodal signals, e.g., video, depth map, motion capture (MoCap), due to the completeness of information they jointly provide. The joint analysis of multimodal signals requires to know the correct timing, i.e., the signals to be aligned. In this paper we propose an approach to automatically estimate the correct matching and alignment between a video and...
Finding suitable developers for a given task is critical and challenging for successful crowdsourcing software development. In practice, the development skills will be improved as developers accomplish more development tasks. Prior studies on crowdsourcing developer recommendation do not consider the changing of skills, which can underestimate developers' skills to fulfill a task. In this work, we...
Feature ranking from video-wide temporal evolution brings reliable information for complex action recognition. However, a video may contain similar features in the sequence of frames which deliver unnecessary information to the ranking function. This paper proposes a method to improve the rank-pooling strategy which captures the optimized latent structure of the video sequence data. The optimization...
Internet-of-Things (IoT) applications grew rapidly in recent years. Deployment of massive machine-type communication (mMTC) with scalability and reliability becomes a challenging issue. The feature of activity sparsity in mMTC devices makes room for us to efficiently handle detection by compressive sensing (CS)-based multi-user detection (CS-MUD). However, the limited resource, such as the design...
The article presents an analysis of correlation-based clustering procedure in cooperative spectrum sensing. The motivation is to assess if it is more beneficial in terms of energy efficiency to group nodes according to the received signal-to-noise ratio (SNR) on the link between Primary User and node or according to the distance between nodes. To this end, a merged clustering measure is introduced...
This article describes a method for recognizing Ukrainian car's license plates of the most common format, which has a high percentage of correct recognition and applied in practice.
Many novel physical assistance devices are beginning to incorporate intelligent robotic systems and mechatronic components. In terms of a human-centered design it is crucial to assess the perceived subjective usability and acceptance of these systems. A questionnaire was thus designed to evaluate novel physically assisting devices in order to support developers in their design decisions as well as...
In modern electronic warfare, it is a severe challenge for the Electronic Support Measure (ESM) system to realize the recognition of the threat radiation source, the modulation of the pulse repetition interval (PRI) is closely related to the function and application of the radar radiation source. Therefore, the recognition of PRI modulation is greatly significance to the identification of the threat...
Public cloud providers, such as Amazon EC2, offer idle computing resources known as spot instances at a much cheaper rate compared to On-Demand instances. Spot instance prices are set dynamically according to market demand. Cloud users request spot instances by submitting their bid, and if user's bid price exceeds current spot price then a spot instance is assigned to that user. The problem however...
This paper investigates the various aspects of the capacity value of photovoltaic systems (PV-systems) and the effect of their penetration levels on power system reliability. Unlike wind power, the available output power of PV-systems can be classified into two specific time periods: certainly unavailable during the night and uncertainly available during the day. In other words, during the night,...
The Dempster-Shafer evidence combination method will appear inconsistent conclusions for the conflict evidence. One new universal evidence combination method was proposed. According to the concept of the Pearson correlation coefficient. Evidence distances which represent the conflict degree were calculated, and then the weight coefficient were further converted. The evidences probability were redistributed...
Softw are quality attributes are specialized requirements derived based on the requirements of the stakeholders during requirement engineering. The software system requires fulfilling the derived set of qualities to achieve high-quality software system. However, achieving a set of quality attributes can be tricky because of the underlying correlation impact among the quality attributes. Most of the...
Disturbances originating in one control loop of a large industrial plant can propagate far from the source, giving rise to plant-wide oscillations. The underlying interactions among the different control loops make it hard to identify the origin of such large scale disturbances. This paper studies the application of the convergent cross mapping (CCM) based technique to isolate the source of a plant-wide...
Brain functional connectivity measured by functional magnetic resonance imaging was shown to be influenced by preprocessing procedures. We aim to describe this influence separately for different preprocessing factors and in 20 different most used preprocessing pipelines. We evaluate the effects of slice-timing correction and physiological noise filtering by RETROICOR, diverse levels of motion correction,...
For the multi-index decision problem with uncertain information, this paper introduces the definition of interval distance of three-parameter interval grey number, proposes the relative degree of grey incidence based on interval distance of three-parameter interval grey number, constructs the grey incidence decision-making model with three-parameter interval grey number, measures the relative degree...
In semiconductor manufacturing for automotive as for many other industries, reliability tests are designed and implemented in order to predict failure rate in real life and applications. Physics-of-failure is used on the rejects observed in field and during the reliability tests to check them to stress the components as in life applications. Besides this qualitative study between field and reliability...
