a significant portion of gross domestic production (gdp) in any country belongs to the transportation system. transportation equipment, in the other hand, is supposed to be great consumer of oil products. many attempts have been assigned to the vehicles to cut down greenhouse gas (ghg). in this paper a novel heuristic algorithm based on clark and wright algorithm called green clark and wright (...
We present a framework to integrate macroscopic traffic flow models with microscopic emission and fuel consumption models. Since macroscopic traffic flow models do not provide the acceleration as an output, while microscopic emission and fuel consumption models require both the instantaneous speeds and accelerations as input, we describe how to generate these variables. In particular, we consid...
Microscopic emission and fuel consumption models have been widely recognized as an effective method to quantify real traffic emission and energy consumption when they are applied with microscopic traffic simulation models. This paper presents a framework for developing the Microscopic Emission (HC, CO, NOx, and CO2) and Fuel consumption (MEF) models for light-duty vehicles. The variable of comp...
The absence of energetic particles commensurate with the energy produced in the Fleischmann–Pons experiment hinders our ability to sort out the microscopic physics involved. Models that we have studied for excess heat are based on the fractionation of the large nuclear quantum to a large number of much smaller quanta. These models predict that it should also be possible to up-convert vibrationa...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
Beta-delayed neutron emission is important for nuclear structure and astrophysics as well reactor applications. Significant advances in experimental techniques the past two decades have led to a wealth of new measurements that remain be incorporated databases. We report on coordinated effort compile evaluate all available ?-delayed data. The different measurement been assessed data compared wit...
The β-delayed neutron emission probabilities of neutron rich Hg and Tl nuclei have been measured together with β-decay half-lives for 20 isotopes of Au, Hg, Tl, Pb, and Bi in the mass region N≳126. These are the heaviest species where neutron emission has been observed so far. These measurements provide key information to evaluate the performance of nuclear microscopic and phenomenological mode...
Here, we collect two parts of a research project on the pedestrian flow modeling. Rapid growth in the volume of public transport and the need for its reasonable, efficient planning have made the description and modeling of transport and pedestrian behaviors as important research topics in the past twenty years. First, we present a macroscopic model for the pedestrian flow based on continuum mec...
Microscopic models of traffic demand and traffic flow have reached a maturity which allows their usage for investigating large-scale effects of measures and/or developments. In microscopic models, every participant is described individually by a set of attributes. Demand models use attributes such as the age, employment state, sex, home location, and the availability of mobility options for com...
