Abstract Artificial neural networks use a lot of coefficients that take great deal computing power for their adjustment, especially if deep learning are employed. However, there exist coefficients-free extremely fast indexing-based technologies work, instance, in Google search engines, genome sequencing, etc. The paper discusses the methods pattern recognition. It is shown recognition applicati...

purpose: to determine the effect of grid pattern laser photocoagulation on diabetic diffuse macular edema with assessment of visual outcome. patients & methods: the author reviewed the medical records of 84 eyes of 62 patients with diabetic diffuse macular edema treated with grid pattern green argon laser photocoagulation in farabi eye hospital between the years 1992-1995, the follow-up period ...

a four-year field experiment was conducted to understand the characters of nutrient accumulation and distribution in maize under different yield levels, so as to provide scientific guidance for effective utilization of mineral fertilizers, and eventually for high yield of spring maize. the grain yield, nutrient (nitrogen, phosphorous, potassium) accumulation and uptake efficiency were evaluated...

the aim of this paper is to review the created problems and failure of environmental design patterns in designing process by designers. not respectfully addressing the context of environment during designing process have resulted in the loss quality of environment, damage to both nature and essence of environment as manifested in the case study area. methodology of the research was based on the...

internationally recognized golestan forests are among the most endangered features threatened by anthropogenic activities. being located in north-west of iran, south-east of caspian sea, gorganroud watershed is mostly influenced by deforestation activities. in this study the identification of regional atmospheric and hydrologic patterns and their role in conforming floods in gorganroud water ba...

abstract the present study was carried out for developing and evaluating of the optimization model of cropping pattern in irrigation networks using analytical hierarchy process (ahp). the model was programmed into two sub-models. the objective of the first sub-model was ranking of crop appropriately, and the objective of the second sub-model was ranking of cropping area of each crop. ten criter...

abstract information about the spatial patterns of soil biodiversity is limited though required, e.g. for understanding effects of biodiversity on ecosystem processes. this study was conducted to determine whether soil macrofauna biodiversity parameters display spatial patterns in the riparian forest landscape of karkhe. soil macrofauna were sampled using 200 sampling point along parallel trans...
