Close-spaced-sublimated (CSS) CdS films exhibit strong fundamental edge luminescence, high optical absorption, and a bandgap of ~2.41 eV. Structurally, these films show good crystallinity with thickness-dependent grain sizes that vary between 100-400 nm. In contrast, chemical-bath-deposited (CBD) CdS exhibits subband luminescence, lower absorption, and a thicknessdependent bandgap. These films ...
این رساله در 4 فصل ارائه شده است. هدف از مطالعه کنونی ساخت و بررسی کاربرد های نانو نیمه رسانا های نور کاتالیزگر تلفیقی بر پایه کادمیم سولفید و زینک سولفید می باشد. برای دسـت یابی به این هـدف، ترکـیب های پودری cds، zns و همـچنـین ترکـیب های cds-30/zns و cds-15/znsکه نسبت cds موجود به zns در تلفیق آن ها به ترتیب 30 و 15% می باشد، با ترکیب کردن زینک سولفید، کادمیم سولفات و سولفید سدیم ساخته شد. مد...
Three experiments evaluated the effects of condensed distillers solubles (CDS) on performance and metabolism characteristics in finishing diets. In Exp. 1, 250 crossbred steers (355 ± 18 kg of BW) were used in a randomized complete block design study and fed 0, 9, 18, 27, or 36% CDS to replace a portion of urea and a 1:1 ratio of dry-rolled corn (DRC) and high-moisture corn (HMC). Dietary fat i...
The connected dominating set (CDS) has been extensively used for routing and broadcast in mobile ad hoc networks. While existing CDS protocols are successful in constructing CDS of small size, they either require localized information beyond immediate neighbors, lack the mechanism to properly handle nodal mobility, or involve lengthy recovery procedure when CDS becomes corrupted. In this paper,...
We develop a composite photoanode by sensitizing TiO2 nanorod arrays with PbS quantum dots (QDs) and CdS QDs. Benefitted from additional introduced PbS QDs and CdS QDs onto TiO2, the absorption of the composite photoanodes are broaden from UV to visible region. The experimental results showed that the PbS sandwiched between TiO2 and CdS cannot only broad the absorption properties but also impro...
An important barrier to the widespread dissemination of clinical decision support (CDS) is the heterogeneity of information models and terminologies used across healthcare institutions, health information systems, and CDS resources such as knowledge bases. To address this problem, the Health Level 7 (HL7) Virtual Medical Record project (an open, international standards development effort) is de...
At present, there are no widely accepted, standard approaches for representing computer-based clinical decision support (CDS) intervention types and their structural components. This study aimed to identify key requirements for the representation of five widely utilized CDS intervention types: alerts and reminders, order sets, infobuttons, documentation templates/forms, and relevant data presen...
In this paper, we present an automatic child-directed speech detection system to be used in the study of child language development. Child-directed speech (CDS) is speech that is directed by caregivers towards infants. It is not uncommon for corpora used in child language development studies to have a combination of CDS and non-CDS. As the size of the corpora used in these studies grow, manual ...
In this paper, the author proposes an algorithm to determine a stable Connected Dominating Set (CDS) for Mobile Ad hoc Networks (MANETs) based on the notion of a metric called the Node Stability Index (NSI) of a node, defined as the sum of the predicted expiration times of the links (LETs) with the neighbor nodes that are not yet covered by a CDS node. The proposed algorithm prefers, to include...
The molecular origin of the photoluminescence of carbon dots (CDs) is not known. This restricts the design of CDs with desired optical properties. We have synthesized CDs starting from carbohydrates by employing a simple synthesis method. We were able to demonstrate that the CDs are composed of aggregated hydroxymethylfurfural (HMF) derivatives. The optical properties of these CDs are quite uni...
