This paper proposes mapping between different sensory modalities for a robot system to generate motion expressing auditory signals or sounds from the movements of objects. Since all correspondences between auditory signals and visual signals in the world are hard to memorize, the ability to generalize is indispensable. We adopted a neural circuit model called RNNPB, which has good generalizatio...

Against the backdrop of increasing energy demands, the threat of climate change and dwindling fuel reserves, finding reliable, diverse, sustainable/renewable, affordable energy resources has become a priority for many countries. Marine energy conversion systems are at the forefront of providing such a resource. Most marine renewable energy conversion systems require tribological components to c...

Introduction: In radiation therapy, determining the location of the tumor accurately during irradiation is one of the most important requirements. However, lung tumors are not fixed in a single location and move during irradiation due to respiratory motion. Due to limitations in assessing such movements, using a lung phantom can be useful and operational for their fast, easy an...

Reliability assessment of reciprocating equipment piston rod leads to nonlinear elastic-plastic deformation analysis of rod with initial imperfection under axial dynamic load. In this paper a new and effective model and analytical simulation method are presented to evaluate dynamic deformation and elastic-plastic stress of reciprocating machine piston rod. This new method has capability to acco...

The strong vibration of reciprocating pump in oil transportation station pipeline system will seriously affect the safe running of the equipment and pipeline. And the resonance between pipe and equipment will cause more severe damage. Therefore before the formal operation of station, not only static stress analysis, but also modal analysis and vibration analysis are necessary for the reciprocat...

INTRODUCTION The purpose of this in vitro study was to assess the amount of apically extruded debris using rotary and reciprocating nickel-titanium instrumentation systems. METHODS Eighty human mandibular central incisors were randomly assigned to 4 groups (n = 20 teeth per group). The root canals were instrumented according to the manufacturers' instructions using the 2 reciprocating single-...

Background. China is the largest producer of rape oilseed in the world; however, the mechanization level of rape harvest is relatively low, because rape materials easily adhere to the cleaning screens of combine harvesters, resulting in significant cleaning losses. Previous studies have shown that bionic nonsmooth surface cleaning screens restrain the adhesion of rape materials, but the underly...

In the article, mechanical and electromechanical starting characteristics of an asynchronous electric drive a two-piston ship compressor are investigated by numerical method. A distinctive feature operation reciprocating is that its load torque changes with certain frequency. The dependence on shaft piston angle rotation presented in form Fourier series. Moments inertia reduced to single system...

BACKGROUND Although retrograde decremental accessory pathways (DAPs) are thought to typically present as permanent junctional reciprocating tachycardia (permanent junctional reciprocating tachycardia), they may also be diagnosed unexpectedly during electrophysiology study. We aimed to compare the clinical and electrophysiological characteristics of patients with DAPs to an age-matched cohort wi...
