iranian traditional cities were created with a system based on experiments and gradual establishment of society through time. qajar era is especially important in iranian art history. until mid qajar era, iranian cities’s architecture mainly took benefit of its common traditional architecture that is already seen in most desert-surrounding cities. till this era, there was not any connection bet...

A parsimonious and compatible system of taper, total, and merchantable volume equations sharing a common vector of three parameter estimates was derived from Clark and Saucier’s (1990) volume ratio model. Clark and Saucier’s model expresses volume inside bark as a function of outside bark diameter and is itself not compatible with the derived taper equation. To ensure compatibility, models were...

We propose a procedure to detect significant changes in forest spatial patterns and relevant scales. Our approach consists of four sequential steps. First, based on a series of multi-temporal forest maps, a set of geographic windows of increasing extents are extracted. Second, for each extent and date, specific stochastic simulations that replicate real-world spatial pattern characteristics are...

This paper reports the development of a new spatial simulation model of landscape dynamics – DINAMICA, which presents: 1) multi-scale vicinity-based transitional functions, 2) incorporation of spatial feedback approach to a stochastic multi-step simulation engineering, and 3) the application of logistic regression or weights of evidence to calculate the spatial dynamic transition probabilities....

the present study aims to simulate the spatial pattern of land use change in lisar protected area,iran. land cover maps for 1989, 2000, and 2007 were depicted using tm, etm+, and irs liss-iii images ofthe area at stake. images were classified using a merge of unsupervised and supervised classification. camarkov model was used to predict land cover maps as a top-down approach in investigating la...

In some tasks that require sustained attention, vigilance levels of the operator might become very important. EEG has been proved very effective for measuring vigilance. However, many difficulties exist in this field such as how to label the EEG data, how to remove the noise from the EEG data and so on. In this paper, we introduce a very useful signal transform method, Common Spatial Pattern, t...

The Common Spatial Pattern (CSP) algorithm is a popular method for calculating spatial lters in motor imagery braincomputer interface system. However, the performance of CSP is in uenced by several factors such as the selection of channels, time window length, frequency band and etc.. One of the existing problems is that some above parameters for CSP is tuned manually in most of papers in the l...

We propose a novel framework for the classification of single trial ElectroEncephaloGraphy (EEG), based on regularized logistic regression. Framed in this robust statistical framework no prior feature extraction or outlier removal is required. We present two variations of parameterizing the regression function: (a) with a full rank symmetric matrix coefficient and (b) as a difference of two ran...
