Tactile stimulation (light stroking) of a body wall flap attached to the ventral nerve cord of the medicinal leech evokes episodes of swimming activity. This swimming response undergoes habituation, involving changes in swim initiation and swim maintenance. Repeated stimulation of the body wall flap evoked swimming activity between three and 39 times before this response failed. During repetiti...

Fuzzy logic inference system (FIS) has been widely applied to the controller design for automatic guided vehicles (AGV) because FIS allows easier controller design under uncertainty and nonlinearity (Hwang et al., 2007; Godjevac & Steele, 1999; Baturone et al., 2008; Er &Deng, 2004; Ng & Trivedi, 1998). Wall following is a commonly adopted scheme for an AGV to navigate in the indoor or outdoor ...

Breast cancer is the leading new cancer diagnosis in women in the United States and is the second most lethal cancer in this patient population after lung cancer. Chest wall recurrence after mastectomy poses unique clinical challenges, as such tumors are often not amenable to surgical resection and durable local control with radiation or systemic therapy is challenging. When uncontrolled, chest...

The path following is the automatic control of the mobile robot along the specified path without human interference. The proposed path following applies for the robot navigation in unknown environments, where the robot has no preliminary information about obstacles. This paper presents an innovative idea for the path following control that is to integrate the basic path following control with t...

Intimal hyperplasia, common at the deployment site of an intra-arterial stent, may be caused by artery wall hypoxia. The purpose of this study was to determine the effect of an intra-arterial stent on artery wall oxygen concentrations. Transarterial wall oxygen gradients were measured by microelectrode at stent deployment sites in New Zealand White rabbits. Thinned artery walls and decreased ox...

In this paper, a mobile robot control law for corridor navigation and wall-following, based on sonar and odometric sensorial information is proposed. The control law allows for stable navigation avoiding actuator saturation. The posture information of the robot travelling through the corridor is estimated by using odometric and sonar sensing. The control system is theoretically proved to be asy...

This thesis primarily describes performance and decision heuristics of human operators intervention with an autonomous formation flight (AFF) system during monitoring of a station-keeping display. Due to mental and physical workloads, automation technologies have been applied to formation flight for precise station-keeping and resultant fuel reduction, shifting control authority from humans to ...
