Affine Transformation Based Ontology Sparse Vector Learning Algorithm

al. [ 8 ], Agapito et al. [ 9 ], Umadevi et al. [ 10 ] and Cohen [ 11 ]). The model of ontology can be regarded as a graph G = ( V , E ), in which each vertex v expresses a concept and each edge e = v i v j represents a directly contact between two concepts v i and v j . The aim of ontology similarity calculating is to learn a similarity function Sim : V × V → ℝ + ∪ {0} which maps each pair of vertices to a score real number. Moreover, the purpose of ontology mapping is to bridge the link between two or more different ontologies based on the

Landslide Susceptibility Assessment in Constantine Region (NE Algeria) By Means of Statistical Models

rates of the FR and WoE methods are in the range of 0.7332–0.7907, indicating a good performance of the models, with a slight differentiation for the WoE model. In the case of the success rates, the IV method shows a low score of 0.5881. This value is less convincing than the two remaining models ( Fig. 5d ). 3.4 Discussion From these calculations, we can say that the slope gradient is the most important parameter for slope stability analysis, because the driving force of mass movement increases with increasing slope. In the study area, the gradients over than

The Quality Estimation of Different Tobacco Types Examined by Headspace Vapor Analysis

Abstract

In order to judge the quality of tobacco leaf, it is necessary to conduct sensory smoke evaluations. However, these are subjective and the results are difficult to quantify. Therefore, we have attempted to establish a quantitative method for evaluating tobacco quality by comparing results of headspace analysis. Forty-seven leaf samples of different types (flue-cured, Burley, Oriental) were analyzed. The first step in this study was to have a panel of experts smoke cigarettes made from the test tobaccos and have them evaluate 10 sensory attributes. The scores were then analyzed by the technique of principal component analysis (PCA). Results showed that the score for the flavor note attribute indicated the type of tobacco and the scores of the other 9 attributes were combined as a total to indicate smoking quality. Following the sensory study, headspace vapors of the test tobaccos were analyzed with a headspace sampler, gas chromatography, mass spectroscopy system (HS-GC-MS), in which the gas sampling loop and the HS-GC transfer line were deactivated. In order to obtain conditions for good reproducibility, the heating temperature and time of the headspace vials were examined. PCA was performed for the headspace vapor (HSV) analysis results for 31 selected peaks. The first and second principal components could be used to classify tobacco types. The third principal component partially indicated differences of smoking qualities. Finally, multiple regression analysis was performed on the HSV analysis results in order to estimate the smoking quality scores. The regression model of all samples combined had a low regression coefficient. Then, we separated the results of the three tobacco types, as we considered that the headspace data might reveal information about the classifications themselves. The final outcome was a regression model that could be applied to each type with a higher accuracy. The variables that entered the models were compared.

Evaluation of radiographers’ and CT technologists’ knowledge regarding CT exposure parameters

Abstract

Introduction: Since the CT operators play an important role in the diagnosis and treatment of diseases and exposing the patients to radiation exposure, they must be aware of all CT parameters which affect the image quality and patient dose and update their knowledge in parallel with the progresses in CT technology. Therefore, the knowledge of radiographers and CT technologists regarding the CT parameters was assessed in this study to identify and resolve any potential deficiencies.

Material and methods: This study was conducted in 2018 among 113 radiographers and 103 CT technologists in Khuzestan province using a three-part questionnaire containing demographic characteristics, general opinion on CT scan dose and questions assessing technologists’ knowledge of CT exposure parameters. Data were analyzed using SPSS software.

Results: Total knowledge scores of radiographers and CT technologists about CT exposure parameters were 36 and 42, respectively. The highest knowledge score among technologist was the knowledge of changing parameters based on patient characteristics and the lowest was in the field of awareness of noise index and diagnostic reference levels.

Conclusion: Total knowledge scores of radiographers and CT technologists about different scan parameters affecting dose and image quality was very low. Reviewing and updating the content of academic education and holding retraining courses are suggested.

Evaluation of phoneme perception based on the digitalized phoneme test in children with cochlear implants

Evaluation of phoneme perception based on the digitalized phoneme test in children with cochlear implants

Early diagnosis of congenital defect of hearing poses new challenges for a multidisciplinary team of pedoaudiologists, ENT (ear-nose-throat) specialists and speech therapists. This study assessed the perception of phonemes in children with a cochlear implant and the possibilities of applying acoustical solutions in the audiologic evaluation. The participants were 17 implanted children, aged 5-9 years, who received a cochlear implant when they were from 18 months to 3 years old. Detection thresholds and discrimination score were assessed. This study also aimed at verifying the possibilities of applying the digital audioprocessing algorithm in clinical practice. The test based on the phonemes aa, uu, ii, ss, sh (Ling 5 sound test) was used. The test was modified in the frequency domain - the main aim of this modification was to improve the precision of the reconstruction of the audible threshold. The results indicated significant correlations between pure tone audiometry results and thresholds of phoneme detection [dB SPL]. The identification score in this group was 95-100% for sound pressure level 65 dB SPL.
