This paper proposes a metering cost minimisation model that minimises sampling cost under the constraints of the required sampling accuracy of clean development mechanism (CDM) energy efficiency (EE) lighting project. Usually small scale (SSC) CDM EE lighting projects expect a crediting period of 10 years given that the lighting population will decay as time goes by. The SSC CDM sampling guidel...

The corridor simulation environment with the capability of modeling various types of traffic control strategies as the external control modules is of critical importance in developing and improving corridor management strategies. In this research, a microscopic network simulation model, Vissim, is used to develop such an environment, where the new stratified Mn/DOT metering algorithm was simula...

Part I: Modeling, Estimation, and RampMetering Control of Freeway Traffic Themain objective of Part I is to develop improved algorithms for freeway on-ramp metering control. Toward this end, two macroscopic traffic models are first introduced and analyzed. The first is a modification of the cell transmission model (CTM) developed by Daganzo. This modified CTM uses cell vehicle densities as its ...

This paper treats the problem of controlling large freeway systems through ramp metering to enhance their efficiency. Following a rigorous discretization methodology, an extension of the CTM model to inhomogeneous freeways with on and off ramps is proposed. Based on passivity theory and the piecewise affine formulation of this model, an LMI formulation is developed to design non-local feedback ...

Objective: In recent years, farmers have shown great interest to using native drill planter rather than complex planters to grow vegetables. Methods: In this study, we tested a native planter Independent variables were the two types of substrate surface (asphalt and plowed field), three ground speed (3, 5 and 7 kph) and four types of seeds (tomatoes, onions, radishes and lettuce). Dependent var...

The purpose of this report is to provide utilities implementing Advanced Metering Infrastructure (AMI) with the knowledge necessary to secure that implementation appropriately. We intend that utilities use this report to guide their planning, procurement, roll-out, and assessment of the security of Advanced Metering Infrastructure. This report discusses threats to the AMI, the likely sources of...

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...

The onramp metering control problem is posed using a cell transmission-like model called the asymmetric cell transmission model (ACTM). The problem formulation captures both freeflow and congested conditions, and includes upper bounds on the metering rates and on the onramp queue lengths. It is shown that a near-global solution to the resulting nonlinear optimization problem can be found by sol...
