Integration of wind units into power system introduce various sources of technical and economical challenges to operation of power system due to its inherent uncertainty and variability. In operation of power system, stochastic wind generation can affect on the system security. In this paper, optimal security-constrained unit commitment (SCUC) in presence of demand response program (DR) based o...

 We propose two mathematical models with weighted utility functions for the fair bandwidth allocation and QoS routing in communication networks which offer multiple services for several classes of users. The formulation and numerical experiments are carried out in a general utility-maximizing framework. In this work, instead of being fixed, the weight for each utility function is taken as a fr...

Abstract A coupled model system, consisting of a distributed hydrological model and an economic optimization model, is applied 1) to investigate regional interdependencies between irrigated agriculture and regional water balance and 2) to identify optimized cultivation strategies. The coupled model system is applied to a case study for the semi-arid Atankwidi catchment in West Africa. The hydro...

Generalized additive models (GAMs) based on the binomial and Poisson distributions can be used to provide flexible semi-parametric modelling of binary and count outcomes. When used with the canonical link function, these GAMs provide semi-parametrically adjusted odds ratios and rate ratios. For adjustment of other effect measures, including rate differences, risk differences and relative risks,...

The intra-annual dynamics of wood formation, which involves the passage of newly produced cells through three successive differentiation phases (division, enlargement, and wall thickening) to reach the final functional mature state, has traditionally been described in conifers as three delayed bell-shaped curves followed by an S-shaped curve. Here the classical view represented by the 'Gompertz...

This paper presents a stochastic bi-objective model to reduce the operation cost and carbon emission of smart railway station along with dependent commercial buildings, according multi-energy hub system's structure. The proposed energy system (EHS) includes power, heating, cooling subenergy hub. recovered obtained from regenerative braking (RB) during train deceleration is utilized supply load ...

BACKGROUND The development of accurate classification models depends upon the methods used to identify the most relevant variables. The aim of this article is to evaluate variable selection methods to identify important variables in predicting a binary response using nonlinear statistical models. Our goals in model selection include producing non-overfitting stable models that are interpretable...

Brucella is an intracellular bacterium that causes the zoonosis brucellosis worldwide. Alveolar macrophages (AM) constitute the main cell target of inhaled Brucella. Brucella thwarts immune surveillance and evokes endoplasmic reticulum (ER) stress to replicate in macrophages via virulence factors. The GntR regulators family was concentrated as an important virulence factor in controlling virule...

Biofuel production has been a greatly discussed topic in Brazil. In 2004, these debates led the country to develop new policies and implement a national program for biodiesel use and production (PNPB) with the intent to foster a sustainable rural development. In this context, the present study aims to assess the impacts of the PNPB on rural development in the Brazilian Legal Amazon, in a region...
