The distributed Brillouin optical sensor allows monitoring physical parameters such as temperature and stress, making them ideal for application in structural monitoring. Currently, the researches focus on improving the detection distance and resolution of these sensors, the laboratory tests are the main tools to checking the results of different theorical proposals. Therefore, the aim of this paper...
On the example of machine-building enterprise expediency use of SADT technologies in perfecting of the main business processes is shown. As-Is model one of key processes is constructed, the analysis is carried out it and To-Be model, taking into account recommendations about its perfecting is offered.
The recent attentions on video analysis have led to the extensive enhancement of computer vision technologies. However, it is still necessary to closely monitor the results of video analysis by human operators. This paper introduces a trajectory-based scene retrieval system that can help human operators look closely at desired scenes based on a trajectory query. The system includes the index and mapper...
The smart substation is an important part of smart grid. By transmitting GOOSE (Generic Object Oriented Substation Event) and MMS (Manufacturing Message Specification) message among devices, the smart substation can realize the functions including, protection, control, alarm etc. Currently available smart substation secondary system's operation and maintenance analysis doesn't take account of the...
The operation error of the electric energy metering device directly affects the accuracy of the electricity trade calculation, so it's very important to ensure the device working accurately. In this paper, three levels of indexes of electric energy meter were selected from the life cycle management, which cover basic information, operational monitoring and site inspection. Then the state evaluation...
The paper is devoted to solving the problem of developing new and improving existing methods of NFV technological solutions analysis on the earlier stages of developing process. A method of analysis functional and non functional requirements of NFV infrastructure realization is proposed. The proposed method bases on mathematical modelling approach. E-network is use as tool for NFV behavioural modelling...
ETL systems are responsible for populating data warehouses' storage structures with historical subject-oriented business data. To do that in the most appropriated manner ETL systems require special computational means, involving frequently the manipulation of large amounts of data that come usually from disparate information sources. Planning and designing ETL systems are very complex tasks, where...
This work investigates sensor signal processing approaches that can be used with a sensor system for direct on-site monitoring of groundwater, enabling detection and quantification of BTEX (benzene, toluene, ethylbenzene and xylene) compounds at μg/L (ppb) concentrations in the presence of interferents commonly found in groundwater. A model for the sensor response to water samples containing multiple...
In wireless ad hoc networks (WANETs), collaboration among nodes is usually inefficient and the network is vulnerable to various attacks. Although some intrusion detection systems (IDSs) and reputation strategies have been proposed to enhance the network's robustness, the significant power consumption they cause will reduce the networks' lifetime. In this paper, we propose a power-efficient mechanism...
Specific requirements and characteristics of primary storage make designing desirable deduplication schemes a sophisticated task. In this paper, we propose DIODE, a Dynamic Inline-Offline DEduplication scheme that provides salient read/write performance and space-saving simultaneously for primary storage systems. DIODE orchestrates inline and offline processes in a dynamic manner. We propose two innovative...
The study deals with the design of an information system for companies' manufacturers' saddlery and harness in Venezuela, which allows offering its users the possibility of developing an effective and efficient performance. To achieve in this paper types Generic Strategies (Porter) is analyzed and the theoretical foundations of the Balanced Scorecard (Kaplan and Norton) also runs as strategic management...
Cyber security is a challenging research problem especially when one considers exponential growth in information technologies. Most previous cyber security research have generally centered on securing and protecting physical resources (computers, network devices, and mobile platforms), protocols and applications. However, little work has focused on the human side and behavior, what motivates cyber...
The next generation of cellular systems are expected to experience a proliferation of the number of emerging use cases alongside supporting high speed mobile broadband services. Massive Machine Type Communication (mMTC), which caters to a large number of low-data rate and low-cost devices, is such an use case. Smart utility meters, automated sensors in farms, and vehicle tracking nodes for logistics...
Condition monitoring of wind turbine gearbox based on cointegration by vibration signals is investigated in this research. Firstly, we establish cointegration model of gearbox in normal condition and analyze the stability of the residuals calculated by cointegration model. According to the principle of cointegration, once gearbox failure occurs, the cointegration relationship is broken and the stability...
Today's buildings provide continuously growing amounts of data monitored from diverse sensors. With regard to the similarly increasing energy needs of buildings, accurate evaluation and analysis of these data can be used in order to improve energy efficiency and reduce overall energy consumption of buildings. Hence, this work introduces a comprehensive framework based on well-known data analytics...
MEMS technology has never been used for a non-imaging wearable ultrasound application, where e.g. lateral resolution is a minor issue. We combine finite element modeling and thin-plate analytic modeling and some measurements on MEMS devices, to optimize the performance of four MEMS layouts for a wearable bladder monitor. An array of square diaphragms, clamped on two sides, appears to be most favorable.
The paper deals with a methodology of detecting and localizing leakages in water distribution networks. Two approaches are presented: based on a hydraulic model of the network, and based on approximate models and fuzzy classifiers. Moreover, a case study concerning applications of the methodology to a real network in Rybnik, Poland is presented. A pilot version of the system has been running since...
This paper proposes a method to help understanding the influence of a game design on player retention. Using Far Cry® 4 data, we illustrate how playtime measures can be used to identify time periods where players are more likely to stop playing. First, we show that a benchmark can easily be performed for every game available on Steam using publicly available data. Then, we introduce how survival analysis...
At present, bridge maintenance management typically consists of regular visual building inspections. Structural damage frequently remains undiscovered until it becomes clearly visible, a situation which makes little economic sense. However, it is often the case that damage and critical reactions to a bridges internal structure occur in inaccessible and concealed places, and are caused by existing...
Service Oriented Architecture (SOA) and Software Product Line (SPL) have individually proven to be Software Engineering concepts, which are creating values for developing software systems. While SOA is being used for developing applications from an orchestration of web services, SPL has ability to prepare core sets of assets and manage with variable components. The combination of SOA and SPL has highlighted...
