Many researches have demonstrated that the spatial information can play an important role in the classification of hyperspectral imagery. This study proposes a modified spectral–spatial classification approach for improving the spectral–spatial classification of hyperspectral images. In the proposed method ten spatial/texture features, using mean, standard deviation, contrast, homogeneity, corr...
This study uses the Genetic Weighted Pyramid Operation Tree (GWPOT) to build a model to solve the problem of predicting high-performance concrete compressive strength. GWPOT is a new improvement of the genetic operation tree that consists of the Genetic Algorithm, Weighted Operation Structure, and Pyramid Operation Tree. The developed model obtained better results in benchmark tests against sev...
Cornelia De Lange is a rare congenital syndrome with multiple anomalies including Facial dysmorphism, hirsutism, height, weight and head circumflex retardations, cardiac defects, gastrointestinal and renal defects and extremity anomaly. Prevalence of this syndrome is 1 to 30000 or 1 to 50000. The diagnosis of this syndrome is based on clinical evidence. Genetic foundation is known to have two...
The purpose of this study was to investigate magnetic resonance imaging (MRI) of the normal feline eyeand optic nerves using T1-weighted and T2-weighted images. A total of 6 healthy female domestic short haircats age 2-2.5 years and weighing 3.2 ± 0.4 kg were selected. Magnetic resonance imaging data werecollected using GEMSOW (Philips) at a magnetic field strength of 1.5 T. Dorsal, sagittal, a...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
In this paper, a novel mathematical model for a preemption multi-mode multi-objective resource-constrained project scheduling problem with distinct due dates and positive and negative cash flows is presented. Although optimization of bi-objective problems with due dates is an essential feature of real projects, little effort has been made in studying the P-MMRCPSP while due dates are included i...
The maximum weighted matching problem is to find a maximum matching in a given graph such that the sum of weights of edges in it is maximum. In this paper, the concept of maximum random fuzzy weighted matching is proposed firstly, and then the maximum random fuzzy weighted matching problem is formulated as expected value model, chance-constrained programming and dependent-chance programming acc...
This paper considers a two-stage assembly flow shop scheduling problem. When all parts of each product are completed in the first stage, they are assembled into a final product on an assembly machine in the second stage. In order to reduce the delivery cost, completed products can be held until completion of some other products to be delivered in a same batch. The proposed problem addresses sch...
anxiety comprises many clinical descriptions and phenotypes. a genetic predisposition to anxiety is undoubted; however, the nature and extent of that contribution is still unclear. extensive genetic studies of the serotonin (5-hydroxytryptamine, 5-ht) transporter (5-htt) gene have revealed how variation in gene expression can be correlated with anxiety phenotypes. complete genome-wide linkage s...
Increasing demand for electricity and consequently running out of fossil fuel resources and negative impact of fossil fuels on the environment has led to the need for finding renewable energy sources. Iran has high potentiality in exploiting wind energy because of its topology and various climatic conditions. For this purpose, optimal places for installing these facilities should be determined...
