The paper presents a passive FPGA-based identification scheme for on-line monitoring and identification of power quality events and system disturbances caused by various power generation (e.g. wind turbines) and consumption (e.g. nonlinear loads) devices. The wide proliferation of distributed renewable energy and green power sources, and rapid changes in utility load types require affordable and robust...
In the current electricity production mix wind energy is claiming a significant part. In order to guarantee stable electricity production predictability of the wind farm operational behaviour is essential. Big data approaches have the potential for a significant role in realizing this goal. In order to gain insights in turbine operational behaviour it is necessary to obtain a farm wide dataset, containing...
We propose to demonstrate HDBExpDetector, a system for analysts to discover bursty events from a thirdparty web database by using nothing but the existing search interface of the web database to monitor and detect sudden changes to aggregates that satisfy certain user-defined conditions.

The identification of vulnerabilities relies on detailed information about the target infrastructure. The gathering of the necessary information is a crucial step that requires an intensive scanning or mature expertise and knowledge about the system even though the information was already available in a different context. In this paper we propose a new method to detect vulnerabilities that reuses...
Modern applications are increasingly being composed from multiple components that require and consume services at dierent layers of the cloud stack. The diverse, dynamic and unpredictable nature of both cloud services and application workloads makes quality-assured provision of such cloud service-based applications (CSBAs) a major challenge. While elasticity and autoscaling gives CSBA providers the...
Network monitoring system plays an important role in ensuring network security and maintaining network stability. Based on the thorough study of the application of the simple network management protocol (SNMP), a network intelligent monitoring model for test internet protocol (IP) network is designed, and a network monitoring system is developed. The system can realize the network equipment operation...
Home energy monitoring system has importance rule in home energy management. Many reports show that it has effectiveness for reducing energy consumption in home. But in medium term and long term of using home energy monitoring system there are some report show the rapidly dismiss of energy saving effective because of user do not pay attention anymore. For improve the traditional home energy monitoring...
The paper puts forward new ideas for the establishment of distributed price monitoring system on based on the Multi-Agent theory, in order to make the price monitoring process intelligent, the fault diagnosis of real-time price intelligent and conflict resolution intelligent. Price monitoring intelligent system based on Multi-Agent, which realize the intelligent operation, control and supervision...
This paper introduces SmartCare, a project revolving around a smart environment especially built to enable aging in place. The paper describes the vision behind SmartCare as well as its translation into a deployed system. The physical incarnation of SmartCare is the SmartCare apartment, an actual apartment in a retirement community. We provide a description the technologies that are deployed in the...
Spectrum policy in the US (and throughout most of the world) consists generally of a set of nationally determined policies that apply uniformly to all localities. However, it is also true that there is considerable variation in the features (e.g., traffic demand or population density), requirements and constraints of spectrum use on a local basis. Global spectrum policies designed to resolve a situation...
With the rise in Air Traffic flow across the world due to advancement in technology and developments in the field of aeronautical engineering, the cases of emergency and panic situations on flights have also emerged at an exponential rate. Every single day, we hear of emergency situations in flights like fires, birdstrikes, diversions, engine failures and emergency landings etc. Across the globe,...
Many of the people around us forget to take medication on time. The proposed model of smart medical box is a single board computer based assistive device for people who suffer with short term memory loss. It is an alarm based device that helps in reminding patients about their medication. The use of Internet of Things (IoT) concepts and health sensing technologies make diagnosis easier and convenient...
The Fish owners of the pet fish are usually distressed when they are away from home environment because they could not feed the fish on time. Both reasons, food starvation and overfeeding risk the health of fish and leads to poor water quality in indoor fish tanks. Thus monitoring the fish feeder is of great importance which can be very beneficial for the fish owners. This work is aimed to design...
Elasticity is a key component of modern cloud environments and monitoring is an essential part of this process. Monitoring demonstrates several challenges including gathering metrics from a variety of layers (infrastructure, platform, application), the need for fast processing of this data to enable efficient elasticity and the proper management of this data in order to facilitate analysis of current...
Recently, due to the development of automobile industry, the number of vehicles is increasing. The traditional parking lots are unable to meet the growing demands from so many vehicles. Therefore, the current parking lots present many problems. Such as, can't find parking spaces quickly, difficult to manage too many vehicles and manual toll collection costs much time. To solve those problems above,...
The need for efficient public transportation system such as buses is rapidly increased due to the increasing in population, the passengers need to know the accurate arrival time of the particular bus to particular station and then plan their journey from their home. Fuel monitoring have been the major problem that most of bus companies looking to solve. This paper developed a bus tracking and monitoring...
This paper proposes a technique based in the graphical cluster analysis to be implemented in Smart Power Quality Analyzers (SPQA), a proposal Instrument Class S, according to the standard UNE-EN 61000-4-30, with the goal of monitoring electrical grids where new events arise as a consequence of the penetration of new energy resources. In the presence of an electrical fault the instrument triggers the...
This paper presents voltage security assessment with application of Phasor measurement unit (PMU) using Decision Tree (DT). An algorithm is developed by CART to identify the most sensitive buses which are most viable and hampered the security of power system. Such buses are ranked in terms of their index called joint bus ranking. PMUs are costly devices and should be placed only on such buses which...
Pulse oximeters use photoplethysmographic (PPG) signals for measurement of oxygen saturation in arterial blood. They measure volumetric changes in the blood flowing through the body, usually extremities such as a finger or an ear lobe. The peripheral pulse signal obtained by transmitted light through the illuminated body extremity, gets modulated by heart synchronous pulse, respiratory activity and...
A Non-Intrusive Load Monitoring (NILM) method, robust even in the presence of unlearned or unknown appliances (UUAs) is presented in this paper. In the absence of such UUAs, this NILM algorithm is capable of accurately identifying each of the turned-ON appliances as well as their energy levels. However, when there is an UUA or set of UUAs are turned-ON during a particular time window, proposed NILM...
