In this paper, utilization of clustering algorithms for data fusion in decision level is proposed. The results of automatic isolated word recognition, which are derived from speech spectrograph and Linear Predictive Coding (LPC) analysis, are combined with each other by using fuzzy clustering algorithms, especially fuzzy k-means and fuzzy vector quantization. Experimental results show that the ...

Three strains of facultatively anaerobic thermotolerant and moderately halophilic bacteria were isolated from two Jordanian hot spring locations. The novel Bacillus strains were short rods, Gram-positive, motile and spore formers. The strains were capable of anaerobic (but not aerobic) growth at 63C, moderately halophilic, able to grow at NaCl concentration range of 12 15 % and at temperatures ...

Face recognition is important in human identification. The biological recognition technique acts as a good method and broad applications in security areas. This work presents a method to improve the face recognition accuracy using a combination of Principal Component Analysis (PCA), and Wavelet Transform. Wavelet Transform is used to decompose the input image with different levels and rearrange...

صخلملا Infertility affects 15% of couples seeking children worldwide and male factor is evident in about 30-50% of the cases. To assess the effect of sperm chromatin integrity on the outcomes of intracytoplasmic injection, sperm DNA compactness was evaluated by acridine orange staining in 40 fertile and 44 infertile men attending one infertility clinic. The results showed no significant differe...

صخلملا The search for novel anticancer drugs continues. This work includes a preliminary study of the effect of two crude extracts of Greek or Mediterranean sage (Salvia triloba L. f.) on three malignant human cell lines and one malignant murine cell line. A boiling water extract and a methanolic extract were prepared from dried leaves of S. triloba. Yields of extraction were 9.8 and 22.4%, res...

سابقه و هدف: در سال­ های اخیر روند رو به افزایش تخریب منابع آب، خاک محیط زیست اثر کاربرد بی رویه مواد شیمیایی موجب ترغیب پژوهشگران کشاورزی ارگانیک سال ­های شده است. با وجود همه اثرات مثبتی که ارتباط مصرف آلی بر روی ویژگی­ فیزیکی مطرح است، هنوز این رابطه نگرانی­ زیادی از نظر مسائل زیست­ محیطی، سلامت دارد. بسته منبع، اغلب دارای مقادیر نسبتا عناصر سنگین می باشند؛ بنابراین اندازه گیری دقیق میزان فل...
