Privacy is a major issue today as more and more users are connecting and participating in the Internet. This paper discusses privacy issues associated with web metering schemes and explores the dilemma of convincing interested parties of the merits of web metering results with sufficient detail, and still preserving users’ privacy. We analyse different categories of web metering schemes using a...

In order to further improve the seeding performance of maize seed-metering device, a pressure-holding precision device for was designed. The is made up several seed rowing modules, which effectively solves problems inconvenient disassembly and complex maintenance current device. working principle introduced, mechanical kinematic analysis seeds during operation carried out. orthogonal test out w...

Ramp metering has been recognized as an effective freeway management strategy to either avoid or ameliorate freeway traffic congestion by limiting access to the freeway. California has applied ramp metering widely in major metropolitan areas. Currently, California has three major ramp metering systems: San Diego Ramp Metering System (SDRMS), Semi-Actuated Traffic Management System (SATMS), and ...

To ensure higher Level of Service (LoS) at urban motorways, new traffic control concepts are being applied since in most cases there is no available space for infrastructural build-up. For urban motorways, the mostly used control methods are ramp metering combined with additional control methods like variable speed limit control (VSLC). This paper gives a review of the current ramp metering app...

Net metering is a utility metering practice that encourages direct consumer investment in renewable energy technologies. Laws and regulations that establish net metering practices now exist in 22 states. Net metering enables electricity customers with small generators to receive a higher value for some or all of the electricity they generate. This is accomplished by allowing the electric meters...

A negative pressure chamber rotary precision seed metering device was designed to achieve the buckwheat sowing goal, solving problems of traditional poor sealing and air suction high power consumption. The planting plate fixedly connected with shell forming a chamber, which rotates around an axis. suitable for designed. Single factor test response surface were carried out on device. Results sho...

This paper reports a reconfigurable microfluidic dilution device for high-throughput quantitative assays, which can easily produce discrete logarithmic/binary concentration profiles ranging from 1 to 100-fold dilution in parallel from a fixed sample volume (e.g., 10 μL) without any assistance of continuous fluidic pump or robotic automation. The integrated dilution generation chip consists of s...

Based on the principle of moment balance, this paper designs a fertilizer application amount online detection device, which is mainly composed two major parts: guide mechanism and metering discharging mechanism.Under electromagnetic reversing buffering mechanism, discharged into device falls alternately storage box units mechanism. Once gravity in greater than suction sucker, board automaticall...
