To address the issues of low efficiency, poor security, insufficient compatibility, and difficulties in traceability associated with high-voltage electric energy metering (HVEEM) device verification methods, this paper proposes a design scheme for remote system (RVS) such devices based on power cloud platform (PCP). The adopts concept “high-precision local sampling + verification” develops acqu...

In order to meet the sowing demand of hybrid rice plug seedling, a horizontal rotary precision seed metering device was proposed. The key structure parameters were designed, kinematics analysis seed-filling process carried out, and main influencing factors seeding performance evaluation index determined. Taking motor speed, eccentric distance disk, layer thickness as test factors, taking qualif...

Unlimited access to a motorway network can, in overloaded conditions, cause a loss of capacity. Ramp metering (signals on slip roads to control access to the motorway) can help avoid this loss of capacity. The design of ramp metering strategies has several features in common with the design of access control mechanisms in communication networks. Inspired by models and rate control mechanisms de...

Smart spaces are those that are aware of their state and can act accordingly. Among the central elements of such a state is the presence of humans and their number. For a smart office building, such information can be used for saving energy and safety purposes. While acquiring presence information is crucial, using sensing techniques that are highly intrusive, such as cameras, is often not acce...

One of the major criticisms of ramp-metering has been the delay caused on the ramps because of the queues created by ramp control strategies. However, recently, several researchers proposed strategies that explicitly take into account ramp queues when determining metering rates. In this paper, an isolated “feedback” based ramp-metering strategy using modeling is presented. In addition to the re...

Privacy-sensitive information can be extracted from the load data which is available in high resolution in smart metering. A number of approaches to privacy-enhancing technologies (PET) have been suggested to provide privacy in smart metering while maintaining (a certain level of) functionality. To date, most of these approaches have not been subjected to real-world use beyond test pilots in mo...

In this paper we present a method of buoyancy-driven centripetal pumping utilizing a heavy, waterimmiscible liquid to displace an aqueous sample radially inwards against the prevailing centrifugal force. Using formerly introduced dissolvable-film valving, we demonstrate metering and bidirectional periodical pumping of a single sample in the radial direction. We then show integrated sample discr...

Painters of the electric power industry, IT has accelerated the development of a smart grid environment. Of Electric Power Industry in the server, watt-hour meter, modem, network, and remote metering and remote meter reading, remote control, and demand is adjustable. Through server optimization techniques to obtain the information of the remote terminal server is installed as a regional, if you...

As a result of recent changes in the policy governing Internet content distribution, such as the institution of per listener royalties for Internet radio broadcasters, content distributors now have an incentive to under-report the size of their audience. Existing metering protocols only protect against inflation of audience size. We introduce the first protocols for audience metering that prote...
