in this study, under the constraint of resource-saving and environment-friendliness objective, based on multi-agent genetic algorithm, multi-objective spatial optimization (moso) model for land use allocation was developed from the view of simulating the biological autonomous adaptability to environment and the competitive-cooperative relationship. the model was applied to solve the practical m...
Spatial count data is usually found in most sciences such as environmental science, meteorology, geology and medicine. Spatial generalized linear models based on poisson (poisson-lognormal spatial model) and binomial (binomial-logitnormal spatial model) distributions are often used to analyze discrete count data in which spatial correlation is observed. The likelihood function of these models i...
Background: Multiple sclerosis (MS ( is one of the chronic autoimmune diseases of the central nervous system with unknown etiology. Nitric oxide (NO) as a free radical has contradictory effect on the central nervous system and on MS disease. Nitric oxide is one of the distractive factors of the immune system and is a factor in the destruction of myelin. On the other hand, there is an interact...
Purpose: The purpose of this study was the Effectiveness cognitive Captain's Log software on visual-spatial perception for student with learning disability. Method: This research was a pretest-posttest design with control group. The statistical population consisted of all students with learning disabilities who were referred to educational and rehabilitation centers of students with specific l...
Hyperspectral anomaly detection is one of the main challenging topics in both military and civilian fields. The spectral information contained in a hyperspectral cube provides a high ability for anomaly detection. In addition, the costly spatial information of adjacent pixels such as texture can also improve the discrimination between anomalous targets and background. Most studies miss the wort...
Aims: From Lufor’s perspective, space is constructed based on spatial operation, recreation and the space in which recreation takes place. This approach is a descriptive view of the relationship between space from a materialistic point of view and its dominant ideas with its dwellers. In this perspective, humans integrate distinct and indistinct data of space and create map-like mental images f...
the statistical analysis of spatial data is usually done under gaussian assumption for the underlying random field model. when this assumption is not satisfied, block bootstrap methods can be used to analyze spatial data. one of the crucial problems in this setting is specifying the block sizes. in this paper, we present asymptotic optimal block size for separate block bootstrap to estimate the...
Aboveground biomass (AGB) of forests is an essential component of the global carbon cycle. Mapping above-ground biomass is important for estimating CO2 emissions, and planning and monitoring of forests and ecosystem productivity. Remote sensing provides wide observations to monitor forest coverage, the Landsat 8 mission provides valuable opportunities for quantifying the distribution of above-g...
Security is a very important issue in the development and dynamics of urban spaces. One of the areas in which security is considered very important in its development is the economic sector, and bazar security is essential as a clear manifestation of economic activities. The Iranian Bazar is one of the important urban spaces and its economic beating heart, and it consists of different spaces, o...
