In audio watermarking, the robustness to desynchronization attacks such as TSM (Time-Scale Modification) operations, is still an open issue. In this paper, both mathematical proof and experimental testing show that the histogram shape (represented as the relative relation in the number of samples among three different histogram bins) and the audio mean are two robust features to the TSM attacks...

Based on the invariant features and data distribution in time domain before and after attacking on the audio, it is clearly that the standard variance shows good invariant statistical feature. The relation of four consecutive bins in a histogram maintains change less than 5%. Then, a general data selection approach, which meets the demands of normal distribution and other distributions, is crea...

شته جالیز Aphis gossypii Glover یکی از آفات مهم و خسارت‌زا با پراکنش گسترده دامنه میزبانی وسیع در مزارع گلخانه‌ها به‌شمار می‌آید. مدیریت رایج به استفاده حشره‌کش‌های شیمیایی منظور جلوگیری خسارت اقتصادی وابسته است. مطالعه حاضر، غلظت‌های کشنده زیرکشنده فلونیکامید دی‌کلرووس طریق زیست‌سنجی برآورد شد تاثیر (LC10 LC25) هر یک آنها روی فراسنجه‌های جدول زندگی شرایط گلخانه‌ای لوبیا چیتی بررسی شد. توجه تأث...
