Hamiltonian Monte Carlo (HMC) is a successful approach for sampling from continuous densities. However, it has difficulty simulating Hamiltonian dynamics with non-smooth functions, leading to poor performance. This paper is motivated by the behavior of Hamiltonian dynamics in physical systems like optics. We introduce a modification of the Leapfrog discretization of Hamiltonian dynamics on piec...

The idea to improve MT quality by using deep linguistic and knowledge-driven information has frequently been expressed. If the goal is to use deep information for building an MT system, there are two extreme options: (1) to start from a purely knowledge-driven approach (RBMT) and try to arrive at the same recall found in current SMT systems; (2) to start from an SMT system and try to arrive at ...

With the aim to improve the steel rolling process performance, this research presents a novel hybrid system for selecting the best parameters for tuning in open loop a PID controller. The novel hybrid system combines rule based system and Artificial Neural Networks. With the rule based system, it is modeled the existing knowledge of the PID controller tuning in open loop and, with Artificial Ne...

An approach for hybrid model parameter identification based on sensitivity equations approach is tested on a hybrid model for biosurfactant production process. The computer simulations were performed using software tools created in Matlab (The MathWorks, Inc.) environment. Possible difficulties and ways of practical implementation of the analyzed identification algorithms for the identification...

supplier evaluation and selection is complex which caused by the dynamic and fuzzy environment. current mcdm methods do not consider the nature of the environment that can affect the process of evaluation and ranking. the aim of this study is to propose a dynamic fuzzy hybrid mcdm method for evaluation, ranking and selection. the proposed method employs fuzzy analytic hierarchy process (fahp) f...

triticale (x triticosecale wittmack) is a hybrid seed plant result from wheat and secale. this seed has high amylolitic and protelytic activities, introducing it as adjuncts in mashing process. in this study, influence of malting process on physico-chemical properties variety of barley (namely sahra) and triticale and malt quality of them were investigate. malt of barley was selected as referen...

this paper aims to present a model for agile supply chain model in construction enterprises with performance evaluation of suppliers and contractors. management and selection of suppliers and contractors plays an important role in process of constructions, because contractors are as corner stones of construction projects. also, contractors are the main factor in converting resources to the fina...

Process simulation is an increasingly useful tool for the analysis of processes in the mineral industry. The ability to simulate process behavior without having to disturb plant operation prevents the loss of man-hours and production. Additionally, simulation tools provide a platform for the development of control and optimization strategies. Model predictive control, in particular, relies heav...
