Poisson and negative binomial regression methods are used to analyze the monthly time series data to determine the effects of introducing an integrated security management system including closed-circuit television (CCTV), door alarm monitoring, proximity card access, and emergency call boxes to a large privately-owned complex of apartment buildings in New York City. Crime rates in a control ap...

Recent works dealing with new considerations about the notion centralizer of equivalence relations gave the opportunity to reveal beyond this construction widerranging phenomenons of functorial nature which do not belong, as it is well-known, to this notion by itself. And this was done in two distinct ways: on the one hand through the notion of action accessible category [2] and on the other ha...

In this paper, we propose a visual assistance system that shows the scene behind a vehicle to its driver in the form of a virtual mirror by utilizing a surveillance camera. The virtual mirror will be displayed on a windshield display as if it were floating in the air in front of the vehicle. The driver entering an intersection can confirm the safety around the vehicle by checking the image in t...

We define the notion of a (P, P̃ )-structure on a universe p in a locally cartesian closed category category with a binary product structure and construct a (Π, λ)-structure on the C-systems CC(C, p) from a (P, P̃ )-structure on p. We then define homomorphisms of C-systems with (Π, λ)-structures and functors of universe categories with (P, P̃ )-structures and show that our construction is functori...

background : mechanical ventilation is used for some infants in neonatal intensive care units (nicu) due to many physiological and clinical causes. since these patients have endotracheal tubes, cleaning and keeping the airways open through suctioning should be done to increase oxygenation. this study aimed to evaluate effect of open and closed suctioning methods on respiratory parameters of inf...

BACKGROUND AND AIM: Nasal fracture is one of the most common facial fractures and the main goal of this study was evaluation of closed reduction surgery of nasal bone fractures.METHODS: Thirty six patients including 24 male and 12 female patients suffered from nasal bone fractures were treated by closed reduction method. Preoperative and postoperative computed tomographic scans were analyzed by...

We propose a semantics for permutation equivalence in higher-order rewriting. This semantics takes place in cartesian closed 2-categories, and is proved sound and complete.
