The phosphate glass samples doped with Tb2O3 oxide (general formula: P2O5-Al2O3-Na2O-Tb2O3) were synthesized and studied for usage in high-dose radiation dosimetry (for example, high-activity nuclear waste disposals). influence of terbium concentration on thermoluminescent (TL) signals was analyzed. TL properties glasses investigated using various experimental techniques such as direct measurem...

rfid system is a wireless technology that can transfer data between tags and readers via radio frequency. in an rfid network, readers are located close to each other to obtain optimal connectivity and sufficient coverage. in such an environment, which is called dense reader environment (dre).different types of collisions such as reader-to-reader and reader-to-tag ones, often lead to serious pro...

BACKGROUND Treatment-limiting decisions (TLD) for severe traumatic brain injury (sTBI) have been sparsely studied. This study determine prevalence, main reason for, categories and timing of TLDs in a Norwegian regional trauma setting. METHODS A retrospective study of a 2-year cohort of 579 sTBI patients admitted to Oslo University Hospital (OUH). Prospectively collected data in the OUH Trauma...

An independent in vivo dose verification procedure for IMRT treatments of head and neck cancers was developed. Results of 177 intracavitary TLD measurements from 10 patients are presented. The study includes data from 10 patients with cancer of the rhinopharynx or the thyroid treated with dynamic IMRT. Dose verification was performed by insertion of a flexible naso-oesophageal tube containing T...

Audiovisual speech perception of children with specific language impairment (SLI) and children with typical language development (TLD) was compared in two experiments using /aCa/ syllables presented in the context of a masking release paradigm. Children had to repeat syllables presented in auditory alone, visual alone (speechreading), audiovisual congruent and incongruent (McGurk) conditions. S...

In this study, the tuned liquid damper (TLD) device was optimized by harmony search (HS) and adaptive algorithms (AHS). Using algorithm, seismic excitations were directed at single ten-story structures, TLD parameters to minimize building movement. To improve design parameters, optimization process repeated adapting factors of algorithm. For purpose, both memory consideration ratio (HMCR) fret ...

Second-order calibration and multivariate spectroscopic-kinetic measurements in the visible region are proposed to improve the Jaffé method for creatinine assay. Analyses performed on synthetic mixtures containing bilirubin, glucose, and albumin confirm that second-order calibration is useful for creatinine determination in human serum. Quantitative determinations of creatinine with the paralle...

This paper studies the DNS cache effects that occur on query distribution at the CN top-level domain (TLD) server. We first filter out the malformed DNS queries to purify the log data pollution according to six categories. A model for DNS resolution, more specifically DNS caching, is presented. We demonstrate the presence and magnitude of DNS cache effects and the cache sharing effects on the r...

Öz Amaç: Bu çalışmada meme kanseri nedeniyle radyoterapi alan gerçek hastayı taklit eden bir fantom üzerinde farklı organlarda absorbe edilen doz araştırılmıştır. Farklı organlardaki ortalama için tedavi planlama sistemi (TPS) ve termolüminesans dozimetre (TLD) ölçümleri karşılaştırılmıştır. Gereç Yöntemler: Alderson kadın rando sol dokusu hedef hacmi olarak seçildi. Varian DHX cihazında teknik...

The implementation of maximum likelihood parallel factor analysis (MLPARAFAC) in conjunction with the direct exponential curve resolution algorithm (DECRA) is described. DECRA takes advantage of the intrinsic exponential structure of some bilinear data sets to produce trilinear data by a simple shifting scheme, but this manipulation generates an error structure that is not optimally handled by ...
