Most of the land use change modelers have used to model binary land use change rather than multiple land use changes. As a first objective of this study, we compared two well-known LUC models, called classification and regression tree (CART) and artificial neural network (ANN) from two groups of data mining tools, global parametric and local non-parametric models, to model multiple LUCs. The ca...
one of the most important applications of multi-objective optimization is adjusting parameters ofpractical engineering problems in order to produce a more desirable outcome. in this paper, the decoupled sliding mode control technique (dsmc) is employed to stabilize an inverted pendulum which is a classic example of inherently unstable systems. furthermore, a new multi-objective particle swarm o...
This study reports the empirical analysis of a hyper-heuristic evolutionary algorithm that is capable of automatically designing top-down decision-tree induction algorithms. Top-down decision-tree algorithms are of great importance, considering their ability to provide an intuitive and accurate knowledge representation for classification problems. The automatic design of these algorithms seems ...
BACKGROUND The effect of transmitted drug resistance (TDR) on first-line combination antiretroviral therapy (cART) for HIV-1 needs further study to inform choice of optimum drug regimens. We investigated the effect of TDR on outcome in the first year of cART within a large European collaboration. METHODS HIV-infected patients of any age were included if they started cART (at least three antir...
Cocaine- and amphetamine-regulated transcript (CART) was originally isolated from rat brain, but CART is also synthesized and stored in the anterior pituitary. The localization of pituitary CART and factors regulating its synthesis are largely unknown. The regulation of pituitary CART synthesis and release in response to CRH and glucocorticoids was examined in vitro and in vivo. CART immunoreac...
از یک سو فقدان اطلاعات کمی در مورد چگونگی پراکندگی گونه¬های گیاهی و عکس العمل آن¬ها نسبت به متغیرهای محیطی، عدم وجود نقشه¬های پراکنش گونه¬ای و از سوی دیگر پیشرفت در تولید لایه¬های محیطی (سامانه اطلاعات جغرافیایی، سنجش از دور و آمار) باعث گردیده است که مدلسازی پراکنش گونه¬ای از اهمیت بالایی در دهه اخیر برخوردار گردد. این مطالعه با هدف مدلسازی و تهیه نقشه رویشگاه بالقوه گونه گون زرد (astragalus v...
This paper investigates consumers' response to conditional promotions (CP) offered in an offline retail store. Using qualitative research inquiry, we decipher the consumer decision-making process by finding linkages between 'pre-cart' and 'post-cart' add-on purchases. Thematic analysis of data (focus groups personal interviews) resulted four themes, i.e. 'Criticality Product Utility,' 'Mode Pay...
CART (cocaine- and amphetamine-regulated transcript) peptides are novel brain neuropeptides that have been shown to have a role in the control of feeding behavior in mammals. The effects of intracereboventricular (i.c.v.) administration of two CART fragments, CART (62-76) and CART (55-102) on feeding and behavioral activity of goldfish (Carassius auratus) were examined. Both CART peptide fragme...
Voltage insecurity is a most vital problem that the modern power systems are imposed off. Timely and accurate assessment of voltage security is necessary to detect post-contingency voltage problems in order to prevent a large scale blackout. The paper presents machine learning techniques based on CART algorithm and probabilistic decision tree based strategy for estimation of voltage security. T...
