Volcanic ash forecasting is a crucial tool in hazard assessment and operational volcano monitoring. Emission parameters such as plume height, total emission mass, and vertical distribution of the emission plume rate are essential and important in the implementation of volcanic ash models. Therefore, estimation of emission parameters using available observations through data assimilation could h...

Wireless communication of the future w ill comprise of several heterogeneous networks whose access technologies will vary to a large extent on the network capacity, data rates, bandwidth, power consumption, Received Signal Strength and coverage areas. With their complementary characteristics, integration of these networks to offer overlapping coverage to mobile users pose many interesting resea...

BACKGROUND This study sought to assess symphyseal morphology in adolescents with different mandibular growth patterns (MGPs) in order to see if a relation exists. MATERIALS AND METHODS In this study the symphyseal parameters (height, depth, and ratio) of normal subjects were compared with four groups with malocclusion (cl III vertical, cl II vertical, cl III horizontal, and cl II horizontal)....

BACKGROUND/AIM Balanced occlusal arrangement of artificial teeth and balanced occlusion is a specific type of occlusion that preserves the stability of complete dentures. Balanced occlusion comprises realization of tooth contacts at the working side as well as at the balancing side, at the same time. The aim of this study was to assess the influence of balanced occlusal arrangement of artificia...

OBJECTIVES To evaluate the potential for machine learning techniques to identify objective criteria for classifying vertical facial deformity. METHODS 19 parameters were determined from 131 lateral skull radiographs. Classifications were induced from raw data with simple visualisation, C5.0 and Kohonen feature maps; and using a Point Distribution Model (PDM) of shape templates comprising poin...

OBJECTIVE To analyze and compare the vertical component of ground reaction forces and isokinetic muscle parameters for plantar flexion and dorsiflexion of the ankle between long-distance runners, triathletes, and nonathletes. METHODS Seventy-five males with a mean age of 30.26 (±6.5) years were divided into three groups: a triathlete group (n=26), a long-distance runner group (n = 23), and a ...

BACKGROUND The sit-to-stand movement requires balance control and coordination between the trunk and lower limbs. For these reasons, it is commonly used in clinics for evaluating lower limb muscle function in the elderly. The aim of the present study was to point out re levant biomechanical and neurophysiological sit-to-stand parameters allowing comparison between elderly fallers and non-faller...

A vertical test grating appears tilted away from a surrounding inducing grating which is 15 degrees from vertical (repulsion effect) but towards an inducer 75 degrees from vertical (attraction effect). This is the tilt illusion (TI) and similar effects occur when inducing and test stimuli are presented successively (tilt after-effect or TAE). When it was reported [Wolfe, J. (1984). Vision Resea...

The purpose of this dissertation was to investigate how different Item Response Theory (IRT)-based calibration methods affect student achievement growth pattern recovery. Ninety-six vertical scales (4 × 2 × 2 × 2 ×3) were constructed using different combinations of IRT calibration methods (separate, pair-wise concurrent, semiconcurrent, and concurrent), lengths of common-item set (10 vs. 20 com...

Due to invisibility and complexity of the underground displacement monitoring, there exit few practical monitoring sensors capable of monitoring the underground horizontal and vertical displacements simultaneously. A novel electromagnetic underground displacement sensor able to monitor both the horizontal and the vertical displacements was proposed in our previous studies and abbreviated as the...
