در این مقاله روش غیرخطی کنترل کننده مد لغزشی موجکی با لایه مرزی تطبیقی از طریق تابع لغزشی متغیر با زمان در خودخلبان پیچشی برای موشک emraat که قابلیت هدایت با مانور btt را دارد، به کارکرفته میشود.سطح لغزشی متغیر با زمان همه فرکانسهای مدل نشده سیستم را فیلتر میکند. پهنای لایه مرزی، پهنای باند شکست فرکانس و پارامترهایی که در تقریب شبکه موجکی عصبی پدید میآیند همگی قابل تنطیم هستند. از اینرو می...
C3-symmetrical, alkoxyphenyl substituted 2,5,8-(tris-1,3,4-oxadiazol-2-yl)benzo [1,2-b; 3,4-b′; 5,6-b′′]trithiophenes (OXD-BTT) are synthesized via threefold Huisgen-reaction. A broad variation of alkoxy substitution pattern and chain lengths is reported. The thermal behavior was investigated differential scanning calorimetry (DSC), polarized optical microscopy (POM) thermogravimetry (TGA). Opt...

Structural modal estimation has consistently remained one of the most crucial areas research in mechanical vibration analysis and signal processing. It is imperative to accurately monitor signals rotor blades their corresponding structural parameters. Blade tip timing (BTT) a promising approach used measure health blades. However, existing BTT methods focus on frequency accuracy, neglecting dam...

Cardiovascular disease is a leading cause of death in North America and Europe, and heart failure represents a major component, affecting about 2.5% of the adult population [1, 2]. Ten percent of the heart-failure population experiences truly advanced heart failure, with limited long-term survival. For patients with New York Heart Association (NYHA) Class IV heartfailure symptoms poorly respons...
Since there are very few prospective trials in patients who undergo LVAD placement as bridge to transplantation (BTT) and very little data on the long-term use of MCS as a permanent alternative to heart transplantation (HT), or destination therapy (DT) , most of the patient selection criteria for LVAD therapy, including the criteria for DT published by the U.S. Centers for Medicare and Medicaid...
PurposeThe International Consortium on Primary Graft Dysfunction is a multicenter, prospective observational study that has collected data over 2700 HT recipients to identify clinical risk factors for PGD in the contemporary era. The objective of this was determine whether BTT with LVAD associated and, if so, high-risk features recipients.MethodsWe from 10 participating sites Europe, United Sta...
The use of the MP2 aproximation with a small basis set is known to reproduce interaction energies for weakly bonded complexes with fairly good accuracy, when corrected for the BSSE. However, it is always a good practice to compare the results obtained in this fashion with higher-level calculations whenever they are computationally allowable. In the case of the BTT-aminoacid complexes studied in...
