We developed an unsupervised machine learning algorithm and applied it to big corneal parameters identify monitor keratoconus stages. A dataset of swept source optical coherence tomography (OCT) images 12,242 eyes acquired from SS-1000 CASIA OCT Imaging Systems in multiple centers across Japan was assembled. total 3,156 with valid Ectasia Status Index (ESI) between zero 100% were selected for the downstream analysis. Four hundred twenty topography, elevation, pachymetry (excluding ESI...
AbstractAbstract<title/>Quartz is usually detected as an impurity of kaolinite clays. The present work attempts to evaluate the role and behaviour quartz particles in geopolymerisation its probable effects on mechanical geopolymeric products. Two clays with different free contents were used raw materials produce geopolymers. Results showed that using high content kaolin causes higher compressive strength. Scanning electron microscopy studies confirmed does not participate completely remains...
Objectives: Reducing infant mortality in the whole world is one of millennium development goals.The aim this study was to determine factors related using data mining algorithms. Methods: This population-based case-control conducted eight provinces Iran. A sum 2,386 mothers (1,076 cases and 1,310 controls) enrolled study. Data were extracted from health records filled with checklists centers. We employed several algorithms such as AdaBoost classifier, Support Vector Machine, Artificial Neural...
The Fe−Ni−TiO2 nanocomposite coatings were electrodeposited by pulse frequency variation. results showed that the with a very dense coating surface and nanocrystalline structure was produced at higher frequencies. By increasing from 10 to 500 Hz, iron TiO2 nanoparticles contentswere increased in expense of nickel content. XRD patterns an enhancement ofBCC phase observed grain size deposits reduced 35 nm. microhardness roughness 647 HV 125 nm Hz due reduction incorporation into Fe−Ni matrix...
This paper presents a lossless data hiding method using integer wavelet transform. The modification of small coefficients the high frequency subbands are used to embed data. We use histogram prepare enough space for hiding. Data embedding is done by processing these selected modified subband histograms. show that we can capacity applying multi-level decomposition and modification. Experimental results our outperforms prior arts in terms larger pay-load.
Background: The use of mobile phones in the field medicine is rapidly increasing developed and developing countries. This study aimed to evaluate performance top applications based on superiority from user's point view medical content. Methods: Information each app was recorded a Google Forms, especially designed for this purpose. Bazaar App Store, which has two main categories health: health fitness, used as source Persian-language Android applications. apps these domains were installed,...
This paper presents a lossless data hiding method using coefficients of integer wavelet domain. The modification selected small the high frequency subbands are used to embed data. We use histogram intelligently select proper for hiding. Data embedding is done by processing these coefficients. show that at low payload our has comparable PSNR than best known reversible techniques, while higher payloads it significant superiority on image quality.
Purpose The purpose of this paper is to fabricate zirconia-nano alumina porous nanocomposites with different amount (0-30 Wt.%). Specimens were prepared by solid state sintering method at temperature (1,400-1,700°C). Design/methodology/approach Effects processing and on microstructure, distribution nanoparticles, flexural compressive strengths, micro-hardness densification investigated. Findings Results indicated that interpenetration particles their contacts increased increasing...
Despite the international recognition of fact that patient can help improve her or his safety, there is little evidence shows how want to take active role. The aim this study was investigate Patients’ Attitudes Toward Receiving Information and Blood Transfusion Safety. This performed by systematic reviewing articles, magazines, foreign books world health organization reports related blood transfusion its auditing. data banks were reviewed electronically. Electronic searches include: Magiran,...
In this paper, we propose a method for cryptanalysis of the Shi reversible data hiding algorithm. We also to improve its security by using concepts in number theory. Our improvement part encrypts four keys before embedding it digital image and detection are used as side information recover original data. Theoretical analysis experimental results shows that finding from marked after applying our proposed algorithm is not feasible reasonable time.
