[1] Using spatially and temporally collocated data sets from the Clouds and Earth’s Radiant Energy System (CERES) and Moderate-Resolution Imaging Spectroradiometer (MODIS) instruments on the Terra satellite, a new strategy is presented for studying the Shortwave Aerosol Radiative Forcing (SWARF) over the global oceans. Using collocated data, for September 2000, the global averaged optical thick...

In this paper we investigate the e®ects of microphone and speaker locations on the performance of active noise control in ducts. We study a so-called \symmetric" con ̄guration in which the collocated performance microphone/control speaker and the collocated measurement microphone/disturbance source pairs are located equidistance from the duct center. By applying an \alignment angle" analysis to ...

in this paper occurrences of precipitation in iran was analyzed according to random processes by the applying of markov chain model. in order to do that occurrence and non-occurrence of rainfall of asfezari data base for the period of 1961/3/21 to 2004/12/31 was used. this data are for 7187 pixel and 15991 days. by using markov chain model first order two state dry and wet frequency matrix was ...

A virtual prototype design and corresponding mathematical model analysis is presented. To obtain a stable and smooth synthesized gait, the zero-moment-point (ZMP) theory and three spline interpolation method have been combined and applied. A novel data-driven model free control strategy, called Time-Delay Estimation based intelligent PID (TDEiPID) combined with Equivalent Sliding Mode Control (...

The high complexity of modern embedded systems impels designers of such systems to model and simulate system components and their interactions in the early design stages. It is therefore essential to develop good tools for exploring a wide range of design choices at these early stages, where the design space is very large. This paper provides an overview of our system-level modeling and simulat...

In this paper, we present a simplified higher-order Markov chain model for multiple categorical data sequences also called as simplified higher-order multivariate Markov chain model. The number of the parameters of the new model is only ) ) (( 2 sm s n O + which is less than ) (( 2 m ns O in the higher-order multivariate Markov chain model. Numerical experiments illustrate the benefits of our n...

n this work, computational fluid dynamics of the flow behavior in a cold flow of fluidized bed is studied. An improved finite volume based finite element method has been introduced to solve the two-phase gas/solid flow hydrodynamic equations. This method uses a collocated grid, where all variables are located at the nodal points. The fluid dynamic model for gas/solid two-phase flow is based on ...

in this paper, we show that the chapman-kolmogorov formula could be used as a recursive formula for computing the m-step-ahead conditional density of a markov bilinear model. the stationary marginal probability density function of the model may be approximated by the m-step-ahead conditional density for sufficiently large m.

Electromagnetic transients (EMT) is the most accurate, but computationally expensive method of analyzing power system phenomena. Thereby, interconnecting several real-time simulators can unlock scalability and coverage, leads to a number new challenges, mainly in time synchronization, numerical stability, accuracy quantification. This study presents such cosimulation, based on digital (DRTS), c...
