In this paper, we present a method to accelerate the speed of querying and retrieving images in database. First we change the storing method: pixels of an image are saved in Hilbert order instead of Row-wise order using in traditional method. Then after studying the property of Hilbert curve, we give a new algorithm which greatly reduce the data segment number on the disk. Although we have to r...

tourism as a growing industry needs special attention in developing countries. during last decades, nature based tourism has been growing faster than other tourism fields and it seems to grow even faster. ever growing demand for nature based tourism emphasizes the necessity of a holistic planning for preserving environment against degradation. objective of this study is to present a nature base...

Assignment problem is an important subject discussed in real physical world. We endeavor in this paper to introduce a new approach to assignment problem namely, ones assignment method, for solving a wide rang of such problems. This method offers significant advantages over similar methods, in the process, first we define the assignment matrix, then by using determinant representation we obtain ...

in order to apply suitable methods for sugar beet seed sowing and determine the relation between yield and growth parameters in saline soils, two salt tolerant progeny lines were sown by five methods for two years (1995 and 1996) using a split plot design. growth parameters such as leaf area index, crop growth rate, total dry weight and relative growth rat were analysed. ph and ec of the soil a...

The effects of periodicity perturbations in underwater phononic crystal layers composed of noninterpenetrating rows of identical shells are investigated. The results for one row are obtained by using a multiple scattering method between shells. Then, taking into account the multiple reflections and transmissions between two adjacent rows, a Debye series method is used to calculate the reflectio...

Among various radio sources which control different dependencies/functions, in this article, we will talk about the Call Admission Control (CAC), and we are supposed to confine our concentration on W-CDMA which is based on high raised platforms, since during the recent years remarkable amount of attention has been focused on platforms located in stratosphere layer [1]. Firstly, we study the cap...

A field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of Roselle (Hibiscus sabdariffa L.) in 2014/15 cropping season at Wondo Genet Agricultural Research Center experimental site (at Wondo Genet station). Two inter-row spacing (60 and 90 cm) and three intra-row spacing (30, 60 and 90 cm) were evaluated using two varieties, WG-Hi...

In this paper, a new statistical projection method called Bilinear Discriminant Analysis (BDA) is presented. The proposed method efficiently combines two complementary versions of Two-Dimensional-Oriented Linear Discriminant Analysis (2DoLDA), namely Column-Oriented Linear Discriminant Analysis (CoLDA) and Row-Oriented Linear Discriminant Analysis (RoLDA), through an iterative algorithm using a...
