We propose a way of synthesizing Thai vowels, monophthong and diphthong which consist of nine short-long vowel pairs and three short-long vowel pairs respectively. By adjusting the fundamental frequency or pitch contour, the five tonal of these vowels can be synthesized, leading to a total of 120 phonemes. We evaluate the synthesized monophthongs by comparing the first and second formants to st...

We present a data set of human activities that includes both visual data (RGB-D video and six Degrees Of Freedom (DOF) object pose estimation) and acoustic data. Our vision is that robots need to merge information from multiple perceptional modalities to operate robustly and autonomously in an unstructured environment.

This paper reports on high-precision recordings of hand-held instrument motion during actual vitreoretinal microsurgery. The movement of a hand-held instrument during vitreoretinal microsurgery was recorded in six degrees of freedom. Data were acquired for 5 min using an inertial sensing module that has been developed for use with a commercially available microsurgical instrument. Maximum veloc...

The aim of this study was to demonstrate the change in separation-individuation between late adolescents in the first, second, third and fourth year of higher education. The study sample used for this longitudinal study consisted of 148 students attending class studies, computer education and science education departments of Kırıkkale University. The Separation-Individuation Test of Adolescence...

I propose a modification of the spherical infall model for the evolution of density fluctuations with initially Gaussian probability distribution and scale-free power spectra. I introduce a generalized form of the initial density distribution around an overdense region and cut it off at half the inter-peak separation accounting in this way for the presence of neighbouring fluctuations. Contrary...

The behaviour based trust models generally compute social trust using interactions of a member with other members, referred to as “friends”. These models largely ignore the interactions of friends with their friends, referred to as “friendship effects”. Results from social studies and behavioural science show that friends have a significant influence on the behaviour of the members in the commu...

Three-dimensional (3D) enveloping grasps for dexterous robotic hands possess several advantages over other types of grasps. This paper describes a new method for kinematic 3D enveloping grasp planning. A new idea for grading the 3D grasp search domain for a given object is proposed. The grading method analyzes the curvature pattern and effective diameter of the object, and grades object regions...

I investigate the link between children living in single-parent households and dropping out of school in Mexico. I focus on how migration structures households, bridging distinct literatures describing the role of single parenthood and migration in the educational trajectories of children. Using two waves of the Mexican Family Life Survey (MxFLS), which includes 3,855 school-age children, I lon...

Presents an approach to improved performance and flexibility in industrial robotics by means of sensor integration and feedback control in task-level programming and task execution. Also presents feasibility studies in support of the ideas. Discusses some solutions to the problem using six degrees of freedom force control together with the ABB S4CPlus system as an illustrative example. Consider...
