Automatic signal type identification (ASTI) is an important topic for both the civilian and military domains. Most of the proposed identifiers can only recognize a few types of digital signal and usually need high levels of SNRs. This paper presents a new high efficient technique that includes a variety of digital signal types. In this technique, a combination of higher order moments and hi...
the cultivar khavaran has come out of the national potato breeding program started in 2001 and continued for ten years in the seed and plant improvement institute karaj, iran. the breeding methodology has initiated by selection among germplasm consisting an open pollination of the clone 397097-13. the khavaran release included single plant selection, visual assessment, preliminary observation n...
High utility itemset mining (HUIM) is a new emerging field in data mining which has gained growing interest due to its various applications. The goal of this problem is to discover all itemsets whose utility exceeds minimum threshold. The basic HUIM problem does not consider length of itemsets in its utility measurement and utility values tend to become higher for itemsets containing more items...
اَبَر بتن خودمتراکم (high performance high strength self compacting concrete, hphsscc)، بتن نسبتا جدیدی است بدون نیاز به ویبره و با مقاومتی حدود 800 kg/cm2 که در صورت استفاده از آن در سیستم های پس تنیده، صرفه جوئی های بیشتری نسبت به چنین بتن هائی با نیاز به ویبره را بدست خواهد داد.

most of hazelnut orchards in iran have been established by planting native genotypes. to enhance productivity of these orchards, adapted and high yielding hazelnut cultivars are to be developed and released. to meet this quest, collection and evaluation of iranian hazelnut germplasm have began by horticultural crops research department, seed and plant improvement institute, iran, since 1994. ha...
in order to develop a high yielding rice cultivar with optimum cooking quality, a cross was conducted between two rice cultivars khazar, high yielding and resistant to blast disease and daylamani tarom, with good cooking quality in 1990. forty pure lines were selected and compared for high grain yield in 1996. ten selected lines together with two check cultivars dasht and onda were tested in ad...
recently, incremental sheet metal forming (ismf) process as one of the new methods in rapid prototyping collection has been considered by researchers. this process is based on a defined path in cnc controller and applies a spherical-head tool that supplies the required pressure for sheet metal forming. despite affirmation of process ability in forming symmetric geometries, some of its aspects s...
applications such as high definition viedeo reproduction, portable computers, wireless, and multimedia demand, and ever-increasing need for ligh-frequency high-resolution and low-power analog-to-digital converters. flash, two-step flash, and pipeline convertors are fast but consume large amount of power and require large area. to overcome these problems, successive approximation converter blo...
this study aimed at examining the effects of iranian efl learners’ anxiety, ambiguity tolerance, and gender on their preferences for corrective feedback (cf, henceforth). the effects were sought with regard to the necessity, frequency, and timing of cf, types of errors that need to be treated, types of cf, and choice of correctors. seventy-five iranian efl students, twenty-eight males and forty...
