The silicon photomultiplier (SiPM) is nowadays an attractive technology in various fields of physics including medical imaging applications. The use of detectors with a large sensitive area has created the necessity to handle detectors with many channels. This has led to the development of data acquisition system for the read-out in parallel of four SiPM matrices with 16 pixels each. The matrices...
Traffic is becoming one of important problems in our society, which is possible to be resolved by the application of the Internet of Things. Based on the analysis of relevant researches on the Internet of Things, this paper proposes the architecture of real-time information collecting and monitoring system. The system integrates several advanced technologies, such as RFID and wireless sensor networks...
Fast and accurate unveiling of power line outages is of paramount importance not only for preventing faults that may lead to blackouts, but also for routine monitoring and control tasks of the smart grid, including state estimation and optimal power flow. Existing approaches are either challenged by the combinatorial complexity issues involved, and are thus limited to identifying single- and double-line...
Over the last two decades, an interesting area of Brazilian military and civil sectors is the Unmanned Aircraft Vehicle (UAV) development. This article tackles the modeling of conflicts resolution of Unmanned Aircraft System (UAS) using a lightweight Duration Calculus (DC) to verify if the temporal specification and design of the system is correct and to ensure formally that the system implementation...
This paper proposes swarm intelligence based approach for the real time coordination of groups of UAVs (Unmanned Aerial Vehicles) in tasks where values that are sensed from the aerial platform can be used to qualify the individuals. In particular, as an example application, here we consider environmental monitoring UAV teams. Their function is to monitor an area and when some undesired environmental...
Collecting and analyzing real-time data of a distributed wireless sensor network system is very challenging since it combines a series of processes to continuously monitor and respond to a wide variety of events. This paper presents an event-driven, real-time data collection system architecture for an independent living spaces monitoring system. A service-replacement-based timestamp matching structure...
Quality of Experience (QoE) is the users' most direct assessment of the network operator's service. How to accurately and efficiently collect QoE data from a point near the user is always a technical challenge to the operators. The way QoE related information submitted to the management system is important because the volume of the data may be excessive enough to interfere with the ordinary chargeable...
Computer networks and more specifically wireless communication networks are increasingly becoming susceptible to more sophisticated and untraceable attacks. Most of the current Intrusion Detection Systems either focus on just one layer of observation or use a limited number of metrics without proper data fusion techniques. However, the true status of a network is rarely accurately detectable by examining...
Smart distribution grid is an important part of smart grid, which connects the main network and user-oriented supply. As an “immune system”, self-healing is the most important feature of smart grid. Major problem of self-healing control is the ‘uninterrupted power supply problem’, that is, real-time monitoring of network operation, predicting the state power grid, timely detection, rapid diagnosis...
This paper proposes a solutions for 35kV integration smart substation. Following the standards in IEC61850, the solution is designed to a three-level equipment and double networking pattern. Considering the substation scale, economical efficiency of investment and corresponding to practical needs of 35kV substation, we integrated plenty equipment and features, which indeed, can substantially reduce...
Automatic EEG spike detection provide valuable information for diagnosis of epilepsy. In the past 30 years, a number of algorithms were proposed. However, the basic idea of most algorithms is to identify spike activities. We have developed an algorithm based on identify non-spike activities for off-line analysis. In this paper, we improved the algorithm for online application using real-time template...
This paper designed a controlling model based on internet technology connecting to grid according to the characteristic that biogas power generator connecting to grid system needs a relatively high response speed and accuracy when processing real-time data. By connecting with the processing characteristics of biogas power generator connecting to grid, the model designed an internet network with a...
Recent work in the Smart Grid field has concentrated on the utilities' requirements, whereas user research on energy awareness and conservation has only been done at a relatively small scale. We attempt to bridge this gap by analyzing the requirements for a grid-wide real time energy monitoring system and combine them with requirements derived from state of the art user feedback applications, both...
Achieving dependable and real-time operation in Wireless Sensor Networks (WSNs) is a hard and open problem. This can be an obstacle for many applications, namely in the automotive and medical domains, particularly if safety-critical control is envisaged. To overcome the communication uncertainties that are intrinsic to wireless and dynamic environments, a generic approach is to constantly adapt to...
Motivated by the need of industrial enterprises for supervision services for quality, security and safety guarantee, we have developed an Activity Recognition Framework based on computer vision and machine learning tools, attaining good recognition rates. However, the deployment of multiple cameras to exploit redundancies, the large training set requirements of our time series classification models,...
Wireless Sensor Networks (WSNs) is an emerging technology holding a great potential for distributed manufacturing automation. The WSN is not only a replacement of the conventional wired sensors, but is a technology that enhances flexible, distributed sensing, and collaborative information processing, which are vital elements for the distributed intelligent manufacturing control paradigm. Currently,...
The user review on a web topic is particular useful information. These reviews usually concern such sentiment or opinions as positive, negative or mixed mood which will affect other users' behaviors, psychological and cognitive activities. Classical web sentiment analysis system could not reach the real-time demand. The functions of online web sentiment analysis system are campus network net flow...
The experience on construction and operation of current Distribution Automation (DA) is summarised in this paper. A pilot project of DA based on Geographic Information System (GIS) is conducted and some effective measures for improving the system are discussed considering the problems in practice. Due to the large quantity of distribution devices and frequent changes, a system interface to achieve...
