This paper describes a trial detection system to monitor the behavior of patients walking along the corridor of a group home for dementia patients. Generally, we do not install video cameras, in order to protect the privacy of the residents. We have developed a simple linear array sensor to detect the behavior of a person walking along the corridor. We have deployed these linear array sensors a...

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...

A fast and reliable transmission mechanism of urgent information is essential for establishing a wireless sensor network infrastructure for a safe and secure living environment. In this paper, we propose a transmission mechanism where high reliability and low latency in transmitting urgent information are achieved by making an “assured corridor” where urgent information is forwarded preferentia...

This paper formulates the vehicle navigation task as a constrained optimal control problem with constraints bounding a traversable region of the environment. A model predictive controller iteratively plans an optimal vehicle trajectory through the constrained corridor and uses this trajectory to establish the minimum threat posed to the vehicle given its current state and driver inputs. Based o...

The corridor allocation problem is one of assigning a given set of facilities in two rows along a straight corridor so as to minimize a weighted sum of the distances between every pair of facilities. This problem has practical applications in arrangements of rooms in offices and in hospitals. The problem is NP-hard. In this paper, we present two population based metaheuristic implementations fo...

Changes in demographics and the burgeoning costs of medical care are putting hospitals in all developed countries under increased pressure. This paper will demonstrate how simulation is contributing to satisfying stakeholders demands for increased efficiency and rates of return as well as improving the potential for geriatric patients reconvalescence and reducing the number of ‘corridor beds’. ...

OBJECTIVE To investigate the long-term results of the corridor operation in the treatment of symptomatic atrial fibrillation refractory to drug treatment. BACKGROUND The corridor operation is designed to isolate from the left and right atrium a conduit of atrial tissue connecting the sinus node area with the atrioventricular node region in order to preserve physiological ventricular drive. Th...

By examining the census tracts and towns that are intersected by Massachusetts' major highway corridors, Diesel and Health along Massachusetts' Highway Corridors ascertains whether these areas contain significantly higher rates of diesel particulate matter (DPM), lung cancer, and asthma. DPM was significantly higher for corridor towns than non-corridor towns. Hot spot analysis revealed statisti...

1. Pursuant to 40 CFR 51.309(d)(3), the WRAP directs its Technical Oversight Committee (TOC) to track emissions and to describe the tracking process in such a way that can be included in state and tribal implementation plans. At a minimum, using the most recent state emission inventories available, the TOC should produce a report for each five-year implementation plan revision on the current an...
