چکیده
In order to reduce the influence of unreasonable road alignment design on vehicle driving safety, a study optimization and safety based two-dimensional point collision dynamics was carried out. First, through model, relationship kinematic parameters before after deduced. Second, according vehicle–road coupling dynamic model analysis collision, threshold between radius circular curve superelevation derived by taking rollover as critical condition. Next, scheme stability proposed. Finally, rationality verified PC-Crash simulation. The simulation results showed that proposed minimum meets requirements rollover. This optimized relevant indicators under premise ensuring provides reference for improvement design. It also has important guiding significance formulation management measures.

Effect of Objective Function on the Optimization of Highway Vertical Alignment by Means of Metaheuristic Algorithms
The main purpose of this work is the comparison of several objective functions for optimization of the vertical alignment. To this end, after formulation of optimum vertical alignment problem based on different constraints, the objective function was considered as four forms including: 1) the sum of the absolute value of variance between the vertical alignment and the existing ground; 2) the su...
متن کاملMaximum Power Point Tracker for Photovoltaic Systems Based on Moth-Flame Optimization Considering Partial Shading Conditions
The performance of photovoltaic (PV) systems is highly dependent on environmental conditions. Due to probable changes in environmental conditions, the real-time control of PV systems is essential for exploiting their maximum possible power. This paper proposes a new method to track the maximum power point of PV systems using the moth-flame optimization algorithm. In this method, the PV DC-DC co...
متن کاملmortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...

A subset W of the vertices of a graph G is a resolving set for G when for each pair of distinct vertices u,v in V (G) there exists w in W such that d(u,w)≠d(v,w). The cardinality of a minimum resolving set for G is the metric dimension of G. This concept has applications in many diverse areas including network discovery, robot navigation, image processing, combinatorial search and optimization....
