Power line communication has recently attracted the attention of energy companies as a useful and natural technology for building the advanced metering infrastructure. In this context, device language message specification/companion specification for energy metering (DLMS/COSEM) is an increasingly popular standardised application protocol for communication between utilities and their customers....

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...

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...

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...

Ramp metering is an effective, viable, and practical strategy used to manage freeway traffic. It is a proven freeway management technique as various forms of ramp control have been in place since the 1960s in the Chicago, Detroit, and Los Angeles areas. Due in part to the success of these early applications, ramp metering has received increased emphasis in recent years under the umbrella of adv...
