This work represents a quantitative assessment of the eco-park theory and its application to a case involving the export of several chemical products in addition to heat and electricity. The network is assessed in terms of environmental impact and profitability relative to existing facilities. GAMS software was employed to create the optimization problem akin to a typical transportation problem...

Integration of wind units into power system introduces various sources of technical and economical challenges to operate power system due to its inherent uncertainty and variability. In operation of power system, stochastic wind generation can affect the system security. In this paper, optimal Security-Constrained Unit Commitment (SCUC) in presence of Demand Response (DR) program based on stoch...

This paper focuses on optimal operation schedule of a Microgrid that is interconnected to the power grid. We develop a mathematical model to compute the optimal operation schedule that embodies demand response. Wind turbine, photovoltaic, fuel cell and micro turbine are considered as the only sources along with energy storage system (ESS) for supplying electricity to the micro-grid. In grid-con...

Distributed lag non-linear models (DLNMs) are a modelling tool for describing potentially non-linear and delayed dependencies. Here, we illustrate an extension of the DLNM framework through the use of penalized splines within generalized additive models (GAM). This extension offers built-in model selection procedures and the possibility of accommodating assumptions on the shape of the lag struc...

We propose a data-constrained generalized maximum entropy estimator for discrete sequential move games of perfect information. Unlike most other work on the estimation of complete information games, the method we proposed is data constrained and requires no simulation or assumptions about the distribution of random preference shocks. We formulate the GME estimation as a (convex) mixed-integer n...

When the Automated Guided Vehicles (AGVs) are transferring the parts from one machine to another in a job shop environment, it is possible that AGVsstopon their guidepaths since their batteries are discharged.Consequently, it is essential to establish at least one Battery Charging Storage (BCS) to replace full batteries with empty batteries for the stopped AGVs. Due to non-predictable routes fo...

Drift wave turbulence is known to self-organize to form axisymmetric macroscopic flows. The basic mechanism for macroscopic flow generation is called inverse energy cascade. Essentially, it is an energy transfer from the short wavelengths to the long wavelengths in the turbulent spectrum due to nonlinear interactions. A class of macroscopic flows, the poloidally symmetric zonal flows, is widely...

The paper documents the energy-economy dataset GTAP-EG which is based on the general Global Trade Analysis Project (GTAP) database and OECD International Energy Agency (IEA) statistics. The GTAP-EG dataset is developed in collaboration with the researchers at Purdue University, who created a GEMPACK version of the energy dataset. In contrast to their work, the GTAP-EG is implemented in the GAMS...

OQNLP and MSNLP are multistart heuristic algorithms designed to find global optima of smooth constrained nonlinear programs (NLPs). By ”multistart” we mean that the algorithm calls an NLP solver from multiple starting points, keeps track of all feasible solutions found by that solver, and reports back the best of these as its final solution. The starting points are computed by a scatter search ...

The excitatory amino acid antagonists D,L-2-amino-5-phosphonovalerate (D,L-AP5), its isomers D-(-)-AP5 and L-(+)-AP5, D,L-2-amino-4-phosphonobutyrate (AP4), D,L-2-amino-7-phosphonoheptanoate (AP7), beta-D-aspartylaminomethylphosphonic acid (ASP-AMP), cis-2,3-piperidinedicarboxylic acid (cis-PDA), and gamma-D-glutamylaminomethylsulphonic acid (GAMS) were tested for their ability to produce a phe...
