Gully erosion is one of the most complicated and destructive forms of water erosion. In order to prevent this erosion, the important factors advancing gully head must be recognized. Nowadays, several models have been proposed in measuring gully head advancement and identifying the severity of erosion. These models must be calibrated for each country to see whether they are applicable or not. So...

Mesacanthus is a common and speciose genus of acanthodian fish from Lower Old Red Sandstone and Middle Old Red Sandstone assemblages (representing the Lower Devonian and Middle Devonian respectively) and is well represented in many palaeoichthyology collections in the UK. Based upon descriptions given during the 19th century, specimens of the genus Mesacanthus from the Orcadian Basin and Midlan...

This article was acceptedfor publication October 1, 1990. Occupational therapy has greatly increased the medical profession's awareness of sensory in­ put and its effect on motor output, based on the foundation proVided by Rood (McCormack, 1990; Trombly, 1989) and Ayres (1973, 1985). From her person­ al experience, Grandin (1986) offered a unique perspec­ tive on the importance of deep pressure...

In this paper, we propose a novel and simple fast block-matching algorithm (BMA), called adaptive rood pattern search (ARPS), which consists of two sequential search stages: 1) initial search and 2) refined local search. For each macroblock (MB), the initial search is performed only once at the beginning in order to find a good starting point for the follow-up refined local search. By doing so,...

the growing population and increasing socio-economic necessitiescreates a pressure on land use/land cover. nowadays, land use change detection using remote sensing data provides quantitative and timely information for management and evaluation of natural resources. this study investigates the land use changes in part of hableh rood watershed of iran using landsat 7 and 8 (sensor etm+ and oli) i...

The adaptive rood pattern search (ARPS) algorithm proposed by Nie and Ma has shown two to three times of search speed-up improvement over that of diamond search (DS) based on the MPEG4 Verification Model encoding platform. In this paper, first we have shown that the distribution of motion vectors bears a rood shape. An improved ARPS algorithm, called ARPS-3 or unequalarm ARPS, is then proposed ...

hazelnut is grown in limited areas of iran with high rainfall and high relative humidity. new cultivars and rootstocks that are tolerant of drought and low humidity are needed to expand hazelnut cultivation. to this end, seeds of 14 local corylus avellana l. genotypes (a1, a2, gerche, gerde eshkevarat, gerde shok, mahalli karaj, nakhon rood, navan1, navan7, navan9, navan10, pashmineh, shirvani ...
