تعیین میزان حساسیت خصوصیات ارتعاشی (فرکانس ها و اشکال مودی) یک سیستم مکانیکی نسبت به تغییر در پارامترهای سازه­ای آن (جرم و سختی) از اهمیت خاصی برخوردار می باشد. روشهای اولیه ارائه شده در این زمینه،بر مبنای آنالیز حساسیت مرتبه اول بوده است. ولی بعلت وجود محدودیت های زیاد در کاربرد آنها، مطالعات گسترده ای برای ارائه روشهای مؤثر وجامع دیگری در این زمینه بعمل آمده است. از جمله این روشها  میتوان به ...

BACKGROUND Knowledge of the factors that influence maternal serum screening (MSS) service utilization can be used to develop health policies to promote equitable access to MSS and further diagnostic tests. The purpose of this study was to find the factors associated with utilization of MSS as well as the current status of service utilization in mainland China. METHODS This was a hospital-base...

Genomic copy number changes are frequently found in cancers and they have been demonstrated to contribute to carcinogenesis; and it is widely accepted that tumors with microsatellite instability (MSI) are genetically stable and mostly diploid. In the present study we compared the copy number alterations and the gene-expression profiles of microsatellite stable (MSS) and MSI colorectal tumors. A...

The Message Scheduled System (MSS) is a composable real-time architecture that allows the extension of systems at runtime without compromising timing guarantees. In this paper, we introduce the MSS architecture and discuss its guarantees as well as the way of proving the holding of these guarantees for any system that follows the MSS architecture.

The present study was conducted to develop a valid and reliable indigenous measure for assessment of menopausal symptoms in Pakistani women. For development of Menopausal Symptoms Scale (MSS), items were empirically generated and were presented on a four point likert scale. A sample of 250 women, ages ranged from 40-60 years, was approached from the gynecology outpatient ward of a public sector...

Despite improved awareness of work-related diseases and preventive measures, many workers are still at high risk of developing occupational hypersensitivity airway diseases. This stems from a lack of knowledge of bioaerosol composition and their potential effects on human health. Recently, archaea species were identified in bioaerosols, raising the possibility that they play a major role in exp...

Cerenkov luminescence (CL) imaging is a new molecular imaging modality that utilizes the photons emitted during radioactive decay when charged particles travel faster than the phase velocity of light in a dielectric medium. Here we present a novel agent to convert and increase CL emission at longer wavelengths using multimodal protein microspheres (MSs). The (64)Cu-labeled protein microspheres ...

From its inception on, the notion of management support systems (MS) has been closely linked to task structuredness. Using data collected with a survey questionnaire, this article presents the results of an empirical analysis of the relation between task structuredness and satisfaction with MS. Two dimensions of task structuredness are distinguished: task difficulty and task variability. The re...

Based on a low-temperature route, monodispersed CoFe(2)O(4) microspheres (MSs) were fabricated through aggregation of primary nanoparticles. The microstructural and magnetic characteristics of the as-prepared MSs were characterized by X-ray diffraction/photoelectron spectroscopy, scanning/transmitting electron microscopy, and vibrating sample magnetometer. The results indicate that the diameter...
