Most of the analysis methods to determine the dynamic response of structures are formulated in terms of vectors and matrices. Because matrices and vectors are not only used for dynamic analysis of discrete systems, but also for system identification of the dynamical properties of systems it is important to have a clear understanding of how matrices and vectors should be properly utilized. This chapter...
Cyberbullying refers to the use of text, images, audio and video to harass or harm individuals or groups on a repetitive and non–stop basis in online social networks. The phenomenon has emerged as a serious societal and public health problem that demands accurate methods for the detection of cyberbullying instances to mitigate the consequences. We perform a detailed analysis of a large–scale real–world...
This paper analyzes the potential of dense time-series Sentinel-1 images for risks management in the drinking water resource. Totally 50 SAR images ranging from March 8, 2015 to August 18, 2017 were employed to monitor land cover/use changes around the Yuqiao reservoir in Tianjin Province, China. Firstly, 49 change maps were obtained by comparing the image acquired on March 8, 2015 with all other...
In the paper are analyzed articles that are indexed on Web of Science with the main topic of the conference “Communication and Information Technologies” (CIT). The articles were chosen the most cited ones. The first step of analysis summarizes statistics of the articles and the second step was oriented to detailed analysis using the software Tovek Tools. The contextual analysis was depicted in the...
Conceptual elevation of data in business process modeling was first formulated in 2003. The research community responded to this new idea enthusiastically. In the past decade, there have been numerous research activities concerning the interactions between business processes/activities and data in many aspects of business process management. Many of the advancements have or will have impacted on design/modeling,...
By the year 2060, the elderly population will double its current size in comparison to the results presented in the last census, according to the Administration on Aging (AoA). By that time an important part of the elderly population will be involved in technology. Moreover, it should be taken into account that the technological needs of elderly people will differ from those of the rest of targets...
This paper introduces a novel system for sports motion analysis. The system utilizes wearable sensors and video cameras to detect a sports motion and to provide image sequences of the motion automatically. Deep neural networks were adopted for detection and explicit segmentation of a sports motion into submotions. The proposed system is evaluated by implementing a soccer kick analysis system as an...
Malicious software poses a great risk to critical infrastructure. Researchers have proposed numerous ways to analyze malware behavior in order to understand and respond to this threat. However, only little attention has been paid to the organization of the malware analysis process itself. In this paper we present the Malware Analysis and Storage System (MASS), a novel framework for malware analysis...
This paper presents a high-resolution near-field magnetic sensing system for nondestructive inspection applications of safety and security. The system includes a probe chip based on a 0.18-μm 5-metal-layer CMOS process technology and a micro-position calibration mechanism. The probe chip includes a magnetic pick-up coil followed by a 3-stage low-noise amplifier to amplify the induced voltage on the...
Author offers timed automaton RT-grammars with a memory to analyze complex business process at manufacturing of the large industrial enterprise. The practical application of RT-grammars to the well-known generalized railroad crossing problem is presented too.
The paper draws attention on the issue of national power system modernization from inside, as a component part included in the multiple set of challenges standing before energy sector development in context of identification of the most feasible projects aimed to offer solutions to overcome problems of Moldova energy sector. When the country lack both own primary energy resources and generation capacity,...
In this work, we studied the feasibility of MSP (Multispectral Skin Photomatrix) module as a new wearable biometrie devices. The MSP device measures optical patterns of the wrist skin tissue. Optical patterns consist of 2 χ 16 photocurrent intensities of photodiode arrays, which is generated by optical transmission and diffuse reflection of photons from LED light sources with variable wavelengths...
The ongoing modernization of today's workplaces within the framework of industry 4.0 is leading to radical new developments and forcing fundamental changes to the way companies and factories are established. The purpose of this paper is to develop and improve a concept that organizes the workplace on a basic level in order to meet the upcoming challenge of accounting for robots as key players in it...
The Internet of Things systems consist of devices, sensors, and services that enable tangible objects to gather and transmit information about the physical world. In order to deliver their main functionality, some of these systems collect a very significant amount of data obtained from their sensors located in living spaces and office environments. This data may hide some interesting behavioral patterns...
Large-scale graph analysis or also called network analysis of networks is supported by different algorithms, among the most relevant are PageRank (Web page ranking), Betweenness centrality (centrality in a graph) and Community Detection, these by of their complexity and the large amount of data that process diverse applications, increasingly need to use computational resources such as processor, memory...
This work analyzes the agro-climatic variables and the water requirements by evapotranspiration for strawberry plantations in the commune of San Pedro. Correlation analysis, principal components analysis, k-means of the time series of the agro-climatic variables and evapotranspiration are used. The periods with need of water are classified to implement a water balance controller.
Highly interactive educational contents using games are widely used, and objective evaluation of these real-time is required. In order to do this, we recorded brain waves under several interactive tasks and game situations in subjects and tried to analyze them. As a result, we focused on the proportion of beta wave components, which suggested the possibility of being able to distinguish between simple...
Companies commonly establish and pursue business goals for different purposes. Many purposes, such as to understand, improve, compare, monitor and control, among others, may be driven by measurement, evaluation and analysis activities. Different strategies can be used to help achieving goal purposes. A strategy defines a set of activities and methods related to nonfunctional requirements, measurement,...
This paper presents web-based graphical schematic editor for analysis of electric and electronic circuits. It is a JavaScript application that uses Spice OPUS and Maple with PraCAn package as a computation engine. In case of linear circuits, results can be obtained in symbolic form. Continuous-time linear and nonlinear circuits as well as periodically switched linear (PSL) circuits can be analyzed...
Literature analysis shows existence of data about weather influence on man's diseases. Selection of diseases in Arkhangelsk region from multifunctional information system was made. Analysis of people prevalence in several human settlements of Arkhangelsk region by means of statistic methods was conducted. The analysis demonstrated dependence of people prevalence on weather conditions as follows: a...
