When hydrologic scientists are looking for data to use in their data models relevant to their research area, they encounter a bottleneck when trying to collect relevant information, sometimes they might not know of all the available sources. Great Lakes Monitoring (GLM) collects data from 5 different state and federal agencies that take measurements on nutrients, geochemicals, contaminants, among...
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...
Testing-as-a-service (TaaS) is a new model to provide testing capabilities to end users. Users save the cost of complicated maintenance and upgrade effort, and service providers can upgrade their services without impact on the end-users. Due to uneven volumes of concurrent requests, it is important to address the elasticity of TaaS platform in a cloud environment. Scheduling and dispatching algorithms...
The monitoring system in coal mine has special requirements for data query. Analysis shows that routing in the system should have four features: data-centric routing, supporting query of geographic position, low delay and high reliability of data transmission, robustness of topology. A mobile agent based routing algorithm with mobile sink and a dynamical weight metric which is derived from its current...
Botnet detection has attracted lots of attention. But few works have considered online detection. In this paper, we propose a novel approach that can monitor the botnet activities in real time. We define the concept of ldquofeature streamrdquo to describe raw network traffics. If some feature streams show high similarities, the corresponding host will be regarded as suspicious bots which will be added...
Wireless sensor network (WSN) is a novel technology in acquiring and processing information and has been an active research area in recent years. In this paper, firstly, a high reliability routing protocol is designed which is able to rapidly detect the change of topological and routing information of network, choose the best route, recover route when some nodes damaged. Secondly, the basic information...
Distributed generation (DG) has impacts on the performance of connected distribution network. DG is usually not requested to participate in voltage regulation of the distribution network and will be disconnected from the distribution network quickly enough when a fault occurs in it for eliminating DG's negative influence. But in this way it will also limit the capability of DG to suppress the voltage...
Along with the maturity of market economy in China, annual salary system has been experimented and subsequently practiced by thousands of enterprises, and then the deficiency in design of the annual salary system has gradually appeared. On the basis of a case of annual salary system of a middle and small- scaled scientific and technical enterprise, it was made that an anticipative analysis of the...
Wireless sensor network is applied widely in monitoring system of coal mine. An application environment of WSN in coal mine is analyzed to satisfy the data acquirement of mine monitoring. The result of analysis shows that routing protocols applied in coal mine should have four characteristics: data-centric routing mechanism, supporting query of geographic position information, low delay and high reliability...
Due to the special and complicated environment in coal mine, the reliability and energy-efficiency are both the primary issues to be considered during the design of the wireless sensor networks (WSNs) for coal mine. In this paper, we put forward a reliable geographical adaptive fidelity (RGAF) routing protocol, which is based on cluster-unit topology (CUT) for the WSNs in coal mine. RGAF utilizes...
Agent distortion issue occurs as traditional Holmstrom- Milgrom model is applied to venture business. To wipe out this difficulty, this paper does reconstructions and extensions towards classical principal-agent theory, brings forward ob-endeavor theorem, validates moral hazard with hidden action, and discovers synergy effect of the endeavor level towards endeavor effect index through calculating...
