Motivation: Based on the known properties of the neurons in the earlier information-processing areas, such as V1, it is possible to make a very quantitative model of how the visual cortex may be organized. In fact, Riesenhuber and Poggio’s HMAX model has been useful in making several physiologically consistent predictions about the properties of the visual cortex [4]. The HMAX model can also be...

Analyzing tree structural features and capturing their temporal dynamic is challenging but crucial for determining key state variables related to plant function, management practices, aboveground vegetation stocks. Terrestrial laser scanning (TLS) provides a mean representing those in three-dimensional space through time. Here we further developed tested two point cloud slice-based methods esti...

The paper presents a new relaxation for hybrid planning with continuous numeric and propositional state variables based on subgoaling, generalising the subgoaling principle underlying the hmax and hadd heuristics to such problems. Our relaxation improves on existing interval-based relaxations by taking into account some negative interactions between effects when achieving a subgoal, resulting i...

چکیده تقطیع یا بخش بندی تصویر یکی از ابزارها و مراحل مهم در تجزیه و تحلیل تصویر و تشخیص اشیا بوده، جزء مباحث پایه ای در سیستم های هوشمند بینایی ماشین به حساب می آید. بخش بندی مبتنی بر بافت تصویر، زیر مجموعه ایی از بخش بندی تصویر است و عبارت است از افراز تصویر به چندین زیر ناحیه به گونه ای که هر زیر ناحیه از ویژگی بافتی یکسانی برخوردار باشد. بخش-بندی بافت تصویر می تواند به کاربردهای مختلفی از ج...

This paper presents a methodology for probabilistic hazard assessment for the multihazard seismic and tsunami phenomena [probabilistic seismic and tsunami hazard analysis (PSTHA)]. For this work, a full-rupture event along the Cascadia subduction zone is considered and the methodology is applied to a study area of Seaside, Oregon, which is located on the US Pacific Northwest coast. In this work...

The binding of oxygen by the haemocyanin of the gastropod Lymnaea stagnalis was studied by equilibrium and kinetic methods. The studies were performed under conditions in which the haemocyanin molecule was in the native state. Over the pH range 6.8-7.6, in the presence of 10mM-CaCl2 the haemocyanin bound O2 cooperatively. Over this pH range the haemocyanin molecule displayed a normal Bohr effec...

The experiment was conducted under a controlled environment to study the effects of different temperature regimes (15/10°C,20/15°C, and 25/20°C day/night) and sowing depths (0, 2, 4, and 6 cm) on the seedling emergence and early growth (height gain) of wheat (cv. Marvdasht) and wild barley (Hordeum spontaneum).The cumulative emergence and plant height gain over time were modeled with the use of...

Abstract The influences of trait diversity (i.e., the niche complementarity effect) and functional composition mass ratio on aboveground biomass (AGB) is a highly debated topic in forest ecology. Therefore, further studies are needed to explore these mechanisms unstudied ecosystems enhance our understanding, provide guidelines for specific management. Here, we hypothesized that would drive AGB ...
