The use of chronically implanted electrodes for neural recordings in small, freely behaving animals poses several unique technical challenges. Because of the need for an extremely lightweight apparatus, chronic recording technology has been limited to manually operated microdrives, despite the advantage of motorized manipulators for positioning electrodes. Here we describe a motorized, miniatur...

Purpose: Wedged beam are often used in clinical radiotherapy to compensate missing tissues and dose gradients. The Elekta Precise linear accelerator supports an internal motorized wedge, which is a single large, physical wedge on a motorized carriage. In this study, the dosimetric performance of Elekta precise three dimensional treatment planning system (3DTPS) is evaluated by comparing the cal...

Abstract In Western industrialized countries, the use of motorcycle has changed from a means transportation to recreational device. As result, this form travel gained more focus by destinations and specialized companies. context, on adventure experience is also increasingly used in customer communication. But there are only few contributions scientific literature which deal with tourism princip...

This study aims to examine if an urban road with intense motorized traffic in a medium-sized Brazilian city constitutes barrier for walking trips. A questionnaire was conducted 103 individuals area up 800 m from the selected obtain information about personal characteristics (age, income, etc.), social interactions neighborhood, and travel mobility characteristics. We used dataset explore potent...

The cost and power consumption of DC power amplifiers are much greater than that of AC power converters. Compared to a motorized spindle supported with DC magnetic bearings, a motorized spindle supported with AC magnetic bearings is inexpensive and more efficient. This paper studies a five-degrees-of-freedom (5-DOF) motorized spindle supported with AC hybrid magnetic bearings (HMBs). Most model...

Introduction: Wedge filters are commonly used in radiation oncology for eliminating hot spots and creating a uniform dose distribution in optimizing isodose curves in the target volume for clinical aspects. These are some limited standard physical wedges (15°, 30°, 45°, 60°), or creating an arbitrary wedge angle, like motorized wedge or dynamic wedge, ... The new formulation is...

INTRODUCTION In order to achieve a minimal trauma to the inner ear structures during array insertion, it would be suitable to control insertion forces. The aim of this work was to compare the insertion forces of an array insertion into anatomical specimens with three different insertion techniques: with forceps, with a commercial tool, and with a motorized tool. MATERIALS AND METHODS Temporal...

This study investigates the daylighting and thermal performance of open-plan office buildings with two scenarios of daylight louvers – fixed and motorized ones. Both types are for facade window applications. They redirect transmitted daylight to eliminate glare on occupants and increase daylight levels deeper in the interior space, but have significantly different daylight transmitting characte...

Active travel (AT) has the potential to integrate with, or in some cases substitute for, trips taken by motorized transportation. In this paper we review relevant research on AT outcomes address of and emerging data sources supporting transport paradigm shift toward AT. Our analysis identifies physical, mental, built physical environmental, monetary, societal outcomes. Traditional methods used ...

Stress is one of many ailments associated with urban living, daily travel a potential major source. Active travel, nevertheless, has been lower levels stress compared to other modes. Earlier work relied on self-reported measures stress, and study designs that limit our ability establish causation. To evaluate effects in different modes an objective proxy measure the galvanic skin response (GSR)...
