در این پژوهش نانو ذرات cds و پوسته/هسته (cds/zns) با استفاده ازروش سنتز شیمیایی مرطوب تهیه شدند و از 3-mercaptopropionic acid (mpa) به عنوان مولکول پوششی استفاده شد. اثر پوسته­ی zns بر خواص اپتیکی و ساختاری cds مورد بررسی قرارگرفت. شدت فوتولومینسانس (intensity of photolumincence) نانو ذرات cds پس از پوشش پوسته­ی  zns افزایش یافت. طیف پراش پرتو x نانوذرات cds پس از گرمادهی در دمای اتاق، ساختار س...

در دهه ی گذشته، نانوبلورهای نیمه رسانا به دلیل نظریه تحدید کوانتومی، هم در تحقیقات تئوری و هم در کارهای تجربی علاقه زیادی را به خود جذب کرده اند. از این میان نانو ذرات cdsبه عنوان مهمترین نیمه رسانای گروه ii–vib، به دلیل ویژگی های بی نظیر اندازه و شکلش بسیار مورد مطالعه قرار گرفته است. نانو ذرات cds، به دلیل ویژگی های غیر معمول فوتوالکتریکی مانند فوتو کاتالیکی و خواص اپتیکی غیر اپتیکی، کاربرد ف...

—Currently, Connected Dominating Sets (CDS) have been widely used to serve as virtual backbones for the topology control of wireless ad hoc networks. Lifetime is one of the most important characteristics of a wireless ad hoc network since mobile nodes are equipped with energy-limited batteries. In this paper, we propose two CDS construction algorithms, CDS-LL and Extended CDS-LL (E-CDS-LL), to...

Eugenol, both in its pure form (EG) and included in essential clove oil (CO) was successfully solubilized in aqueous solution by forming inclusion complexes with β-cyclodextrins (β-CDs) and its modified hydroxypropyl-β-CDs (HP-β-CDs). To investigate the molecular association between β-CDs/HP-β-CDs with pure EG and essential CO, phase solubility studies were undertaken. Essential CO formed insol...

We propose an algorithm to determine stable connected dominating sets (CDS), based on the predicted link expiration time (LET), for mobile ad hoc networks (MANETs). The proposed LETbased CDS algorithm is the first such algorithm that constructs a CDS based on edge weights represented by predicted link expiration time, rather the traditional approach of using node weights like the wellknown maxi...

Active contours and minimal paths have been extensively studied theoretical tools for image segmentation. The recent geodesically linked active contour model, which basically consists in a set of vertices connected by paths of minimal cost, blend the benefits of both concepts. This makes up a closed piecewise-defined curve, over which an edge or region energy functional can be formulated. As an...

Clinical decision support (CDS) systems link patient data with an electronic knowledge base in order to improve decision-making and computerised physician order entry (CPOE) is a requirement to set up electronic CDS. The medical informatics literature suggests categorising CDS tools into medication dosing support, order facilitators, point-of-care alerts and reminders, relevant information disp...

We propose an algorithm to determine stable connected dominating sets (CDS), based on node velocities, for mobile ad hoc networks (MANETs). The proposed minimum velocity-based CDS (MinV-CDS) algorithm prefers slow-moving nodes with lower velocity, rather than the usual approach of preferring nodes with a larger number of uncovered neighbors, i.e., larger density (referred to as MaxD-CDS). The c...

BACKGROUND Computer-based clinical decision support (CDS) systems have been shown to improve quality of care and workflow efficiency, and health care reform legislation relies on electronic health records and CDS systems to improve the cost and quality of health care in the United States; however, the heterogeneity of CDS content and infrastructure of CDS systems across sites is not well known....

BACKGROUND Clinical decision support (CDS) has been shown to be effective in improving medical safety and quality but there is little information on how telephone triage benefits from CDS. The aim of our study was to compare triage documentation quality associated with the use of a clinical decision support tool, ExpertRN©. METHODS We examined 50 triage documents before and after a CDS tool w...
