Accurate estimation of glottal closure instants (GCIs) and opening instants (GOIs) is important for speech processing applications that benefit from glottal-synchronous processing. This paper proposes a novel improvement to the DYPSA framework, based upon a multiscale analysis technique and an accurate estimation of glottal volume velocity. This replaces the linear prediction residual for candi...

with the introduction of communicative language teaching, a large number of studies have concerned with students’ oral participation in language classrooms. although the importance of classroom participation is evident, some language learners are unwilling to engage in oral activities. this passivity and unwillingness to participate in language classroom discussions is known as “reticence”. rev...

The ZnCrFeO4 nanoparticles were synthesized as antiferromagnetic material using sol-gel method. The X-ray diffraction (XRD) analysis and transmission electron microscopy (TEM) certified that ZnCrFeO4 nanoparticles have single-phase cubic structure with a range of 50–100 nm in size. A facile and sensitive analytical method was developed for simultaneous determination of sun...

PURPOSE Contrast, sharpness, enhancement, and density can be changed in digital systems. The important question is to what extent the changes in these variables affect the accuracy of caries detection. MATERIALS AND METHODS Forty eight extracted human posterior teeth with healthy or proximal caries surfaces were imaged using a photostimulable phosphor (PSP) sensor. All original images were pr...

This communication describes a simple sensitive one-step potentiometric aptasensing method for quantitative detection of referenced therapeutic biomarker (programmed death-ligand 1, PD−L1). The aptasensor is constructed by modifying PD−L1-specific aptamer on Ti3C2-MXene nanosheets-functionalized electrode. Introduction PD−L1 induces the specific reaction between and aptamer, thereby resulting i...

Abstract—A GPR object detection algorithm delivers a promising performance using the Hough transform through a high computational load. This paper presents a fast Hough-based algorithm. To reduce the parameter space of the Hough transform, first, two parameters for a reflection hyperbola were estimated using cross correlation between adjacent A-scans. Next, only a 1D Hough transform is necessar...

In this paper we introduce a real recognition system for intelligent vehicles proposed is fully based on image processing. Detection step is achieved in grayscale with spot light detection, and recognition is done using our generic “adaptive templates”. The whole process was kept modular which make our TLR recognizing different traffic lights from various countries. To compare our image process...

Unmanned aerial vehicles (UAV) have been widely used to capture and down-link real-time videos/images. However, their role as a low-cost airborne platform for capturing high-resolution, geo-referenced still imagery has not been fully utilized. The images obtained from UAV are advantageous over remote sensing images as they can be obtained at a low cost and potentially no risk to human life. How...

for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
