With the advantages of reasonable structure, convenient installation and easy transportation, the module drilling rig instead of the traditional oil rig, has been more widely used in offshore oil fields. However, due to its module design, there are still some problems such as low-level of automation and difficulties of monitoring and management of the whole system. In this paper, a supervisory control...
Making Smart Energy Cities (SEC) a reality requires an intelligent and integrated assessment and consideration of various data sets, as well as relevant intelligent systems in a transparent and accessible manner. The scope of this paper is to present an innovative package of decision support tools (entitled “OPTIMUS”) for energy managers and energy consultancies, in order to make cities more energy...
Agricultural Information System is an integrated system that the data is recorded, reported and outcomes are observed in Turkish Agriculture. Agricultural Information System is an informative system, which gathers all data, information and processes belonging to all agricultural activities due to the activity types, which provides follow-up, processes of institutional assignment and inspection and...
Tropical Rainfall Measurement Mission (TRMM) is an useful data for different application, whereas the data was less used in monitoring the meteorological drought in arid regions. In this study, we investigated the spatial-temporal process of a meteorological drought event (occurred at middle reach of Heihe River basin from May 2009 to September 2009) use TRMM 3B43 precipitation data product and observed...
The frequent occurrences of drought in the Great Plains of United States have led to significant crop loss. Timely monitoring of drought-induced agricultural impacts, especially at a large scale from remote sensing, is of great importance for ensuring food security. Following the authors' prior drought impact work in Kansas, based on MODIS data, this study investigated the impacts of drought on winter...
Monitoring and fault diagnosis systems are vital for industrial robot systems for better awareness of system status and shortening the down time. In many cases, the monitoring systems are not upgraded after the robot first installation, because the modifications could cause undesired disturbance for the production. However, for better monitoring and diagnostics rich information is essential that typically...
With growing complexity of premium cars, the end-of-line test systems also increase in complexity. The test systems have to provide more and more functionality like flashing of electronic control units (ECUs) and sensor calibration. Current end-of-line test systems evolved to complex networked IT-systems, which consist of various components and subsystems from different suppliers. Automotive production...
The self-sustainability of micro grids is an important challenge in the smart grids field due to the need to balance the fast growing energy consumption, reduce greenhouse gas emissions and increase energy independence by using renewable resources. The use of decentralized paradigms, and particularly multi-agent systems and holonic control, enable to face this challenge by implementing intelligent...
Media production networks deal with large and predictable video transfers and streaming sessions which need to be scheduled to optimally use the limited network capacity. As the time and locality of transfers are predictable, advance bandwidth reservation results in more effective use of the underlying network. To offer reliable reservations, the incorporation of fault-tolerance related features in...
Motivated by frequent failures in cloud computing systems, we analyze failure frequency and continuity of tasks from the Google cloud cluster, and find what we call killer tasks that suffer from frequent failures and repeated rescheduling. Killer task can be a big concern in cloud systems as it causes unnecessary resource wasting and significant increase of scheduling workloads. In this paper, we...
The cost effectiveness of micro-wind technology is closely linked to the annual energy production plants, which strongly depends on the wind characteristics and on the morphological properties of the installation site. The power curve of a wind turbine, supplied by manufacturers, characterizes the theoretical energy performance that it should have at a particular site. The behavior of a wind turbine...
This paper describes the operation and calibration modes for an experimental monitoring system of a photovoltaic (PV) plant with greater emphasis on the Maximum Power Point Tracker (MPPT). In order to optimize the energy production and therefore the economic convenience, it is very important that MPPT device works properly and that the measurement of PV electrical quantities is not affected by excessive...
This paper proposes a monitoring approach based on single string real-time measurements. An electronic board was developed able to sense string voltage and string current along with open circuit voltage and short circuit current of a selected solar panel belonging to the string. Acquired information allowed real time monitoring of the power actually produced by each string. At the same time, information...
An energy-informatic-centric smart campus represents a viable structure addressing to different groups of users, like: students, teachers/educators, researchers and technical administrators, using information and communications technology system interface for accessing various services and requiring real time information regarding university buildings energy consumption and production, air quality...
This paper presents a novel system which has been developed to supervise in real time the operation of a Grid-Connected Utility-Scale PV Power Plant in order to ensure a reliable and uninterruptible power supply. The system is composed of a complex acquisition architecture which measures the required information with a high temporal resolution and using a high-precision protocol for synchronizing...
The operation of different energy sources in a MicroGrid (MG) has to be monitored and controlled by means of the Energy Management Systems (EMS) both in the grid-connected and islanded modes. In the first case, the MG can be seen as a single controllable unit by the grid operator whereas in the islanded mode the successful balance between internal load and planned generation is also required. In this...
This paper proposes an innovative strategy to optimize the energy metering in large and energy-consuming plants such as industrial flour mills. The proposed solution deals with ISO 50001 implementation which represents a critical challenge for many companies because the benefits due to improvements in energy management could be potentially canceled by the costs of an Energy Management System (EnMS)...
Over the past few years there has been an increasing use of informatics means in the school, as an essential mechanism to make the much desired change and modernization. However, this not translated into a simplification of administrative procedures. This paper describes a project that aims to focus the entire evaluation process in a single web application, allowing create autonomous mechanisms of...
The aim of this paper is to present the benefits of the use of Supervisory Control And Data Acquisition (SCADA) system for the deployment of a micro-grid supplied by hybrid energy system in remote sites and unconnected grids. A microgrid, based in the experimental test site of TechnoCentre éolien (TCE) at Riviere-au-Renard (Québec), and equipped by a SCADA system has been selected as case study for...
The reduction of equipment variability of availability can significantly reduce cycle times, improve yields, reduce time-to-market and lower overall operational costs. Despite extensive efforts to reduce variability of availability, however, the execution of preventive maintenance (PM) is still one of the main sources of equipment variability of availability in the industry. In this paper, a model...
