In this paper we discuss a number of the ways in which the recognition accuracy of automatic speech recognition systems is affected by ambient noise in the automobile, along with the extent to which various techniques for robust speech recognition can provide for more robust recognition. We consider separately the effects of engine noise, interference by turbulent air outside the car, interfere...

Introduction Park visitors' travel choices and behavior are longstanding concerns for the National Park Service. Travel behaviors can affect natural and cultural resources and the quality of the visitor experience. Driving park roadways has been central to the Ameri can national park experience since the earliest days of park preservation. As historian David Louter (2006) argued in his book Win...

Traumatic brain injury, or TBI, is an unfortunate consequence of many civilian accident and military combat scenarios. Examples include head impact sustained in sports activities and automobile accidents as well as blast wave loading from detonated improvised explosive devices (IED). In the United States, over 5 million people live with disabilities associated with TBI (online report at www.cdc...

Wind-shield walls decrease the velocity of wind-drift sand flow in transit. This results in sand accumulating in the wind-shadow zone of both windshield wall and track line, causing severe sand sediment hazard. This study reveals the characteristics of sand accumulation and the laws of wind-blown sand removal in the wind-shadow areas of three different types of windshield walls, utilizing three...

Abstract In the past decades, studies of materials with transparency and durable superhydrophobicity have captured much attention because versatile uses in outdoor glass wall, automobile windshield solar panel. this paper, a superhydrophobic transparent SiO 2 film transmittance over 44% was obtained on substrate facile method dip-coating without further modification. The contact angle sliding w...

In this paper, we attempt to present the design algorithm of the windshield wiper mechanisms. In order to analyze the windshield wiper mechanisms, three mechanical models are developed: kinematic model – to evaluate and optimize the kinematic function of the mechanism; inverse dynamic model – to determine the crank turning torque applied to the input element in order to generate the kinematical...

In this paper, a quad-port multiple-input multiple-output (MIMO) semitransparent antenna is designed for automotive applications. The transparent soda lime glass substrate used in the prototype windshield applications, and radiator nontransparent copper metal. unit cell of MIMO similar to “NISSAN automobile-like” logo. proposed has −10 dB impedance bandwidth 3.4 11 GHz. edge-to-edge distance be...
