This paper presents and compares 3 methods for the statistical localization of partially occulted landmarks. In many real applications, some information is visible in images and some parts are missing or occulted. These parts are estimated by 3 statistical approaches : a rigid registration, a linear method derived from PCA, which represents spatial relationships, and a non linear model based up...

This paper proposes a model predictive control (MPC) approach for non-linear systems where the dynamics are embedded inside linear parameter-varying (LPV) representation. The MPC problem is therefore replaced by an LPV problem, without using linearization. Compared to general MPC, advantages of this that it allows tractable construction terminal set and cost, only single convex program must be ...

A common method to study the dynamic behavior of macroeconomic variables is using linear time series models; however, they are unable to explain nonlinear behavior of the series. Given the dependency between stock market and derivatives, the behavior of the underlying asset price can be modeled using Markov switching process properties and the economic regime significance. In this paper, a two-...

This study aims to evaluate the impact of pavement physical characteristics on the frequency of single-vehicle run-off-road (ROR) crashes in two-lane separated rural highways. In order to achieve this goal and to introduce the most accurate crash prediction model (CPM), authors have tried to develop generalized linear models, including the Poisson regression (PR), negative binomial regression (...

The Vicsek model describes the evolution of a system composed by different agents moving in the plane. Each agent has a constant speed and updates its heading using a local rule depending on the headings of its “neighbors”. Although the original model by Vicsek is non-linear, most of the convergence results obtained so far deal with linearized versions. In this paper, we introduce a new linear ...

Considering profiles as functional variables, two control charts are proposed for their monitoring in phase II. Due to its conformity with the nature of real-world profiles, applying functional model leads to proposed control charts obtained through functional data analysis techniques with desired features. These include simplicity in calculation and possibility of using them for different prof...

cfrp composites have unique application qualities such as high resistance and durability to environmental conditions, having relatively low weight and easy to install in strengthening concrete structure elements. the brackets should be strengthen sufficiently if they are not calculated and implemented well. application of the cfrp is one of the methods for such purposes. the study involves usin...

in this paper, firstly by using a mixed linear programming a new model of locating facilities with limited capacity is presented to design a closed-loop supply chain in a multi-product and multi-period mode. then, using a robust optimization approach, the proposed model decreases in non-deterministic expansion. the results show that the proposed model can handle facility capacity in a closed lo...
