All natural flyers equip flexible wings. It’s widely thought that the wing flexibility can play important roles in flight aerodynamics. In the current work, a combined experimental and computational method is developed to study the role of morphing wing in hovering dragonfly aerodynamic performance. We start with taking high-speed images of a freely flying dragonfly. Next, a surface reconstruct...

This paper proposes a voice morphing system for people suffering from Laryngectomy, which is the surgical removal of all or part of the larynx or the voice box, particularly performed in cases of laryngeal cancer. A primitive method of achieving voice morphing is by extracting the source's vocal coefficients and then converting them into the target speaker's vocal parameters. In this ...

This paper presents two algorithms, based on conformal geometry, for the multi-scale representations of geometric shapes and surface morphing. A multi-scale surface representation aims to describe a 3D shape at different levels of geometric detail, which allows analyzing or editing surfaces at the global or local scales effectively. Surface morphing refers to the process of interpolating betwee...

An alternative technique for shape morphing using a surface generating method using partial differential equations is outlined throughout this work. The boundaryvalue nature that is inherent to this surface generation technique together with its mathematical properties are hereby exploited for creating intermediate shapes between an initial shape and a final one. Four alternative shape morphing...

Vocal effort modification of natural speech is an asset to various applications, in particular, for adding flexibility to concatenative voice synthesis systems. Although decreasing vocal effort is not particularly difficult, increasing vocal effort is a challenging issue. It requires the generation of artificial harmonics in the voice spectrum, along with transformation of the spectral envelope...

Introduction: The inferiorly and laterally based platysma myocutaneous flap contains hair in some ethnics; therefore, it is required to change the myocutaneous flap to myofascial flap to prevent the hair growth after its transfer to the oral cavity.   Materials and Methods: Five male mongrel dogs were selected for this study. De-epithelialized laterally based platysma fl...

Background: The standard methods for reconstruction of soft tissue defects in the leg include gastrocnemius flap for proximal third defects, soleus flap for middle third and free flap in the distal third. However, there are problems with the use of free flap, like increased operative time, damage of major vessels and the need for experienced microsurgeon. Mathods: This prospective study was und...

BACKGROUND Chemical space is virtual space occupied by all chemically meaningful organic compounds. It is an important concept in contemporary chemoinformatics research, and its systematic exploration is vital to the discovery of either novel drugs or new tools for chemical biology. RESULTS In this paper, we describe Molpher, an open-source framework for the systematic exploration of chemical...

Visual morphing is a class of techniques that deal with the metamorphosis of one image into another, which generates a series of smoothly continuous intermediate images between two given images. Over the past few years, a number of computable models of visual morphing have been developed. However, most of these models are based on the pixel domain. Little theoretical and computational work of v...

the distal third of the tibia, ankle and heel area is difficult to reconstruct. for small to medium size defects, local flaps are often an easier alternative than free flap. in lower limb surgery, the sural flap is based on this principle and this flap is becoming increasingly popular. the distally based superficial sural artery flap, first described as a distally based neuro skin flap by masqu...
