Vehicle Traffic Driven Camera Placement for Better Metropolis Security Surveillance
Security surveillance is one of the most important issues in smart cities, especially in an era of terrorism. Deploying a number of (video) cameras is a common surveillance approach. Given the never-ending power offered by vehicles to metropolises, exploiting vehicle traffic to design camera placement strategies could potentially facilitate security surveillance. This article constitutes the fi...
متن کاملBoron Sheets and Boron Nanotubes
Based on an ab initio study, we present a structure model for a broad boron sheet, which is the precursor of boron nanotubes. Furthermore we could show that, in contrast to the armchair types, zigzag boron nanotubes have no surface tension (strain energy). As result, we predict that boron nanotubes will exhibit a chirality dependent stability, something that is unique among all nanotubular mate...
متن کاملModeling Comma Placement in Chinese Text for Better Readability using Linguistic Features and Gaze Information
Comma placements in Chinese text are relatively arbitrary although there are some syntactic guidelines for them. In this research, we attempt to improve the readability of text by optimizing comma placements through integration of linguistic features of text and gaze features of readers. We design a comma predictor for general Chinese text based on conditional random field models with linguisti...
متن کاملPercutaneous fluoroscopic gastrostomy catheter placement: is larger better than small bore?
Aim: To compare the dysfunction and complication rates of small bore and large bore gastrostomy catheters. Material and Methods: A total of 521 patients (291 males, 230 females, mean age 56 years, range 16-90 years) underwent percutaneous fluoroscopic gastrostomy placement between August 2000 and January 2009. Choice of catheter was based on the preference of the Radiologist. Data was collected...
متن کاملOptimal Placement of Phasor Measurement Unit for Better Power System Observability
Secure and reliable opertation of the grid requires real time monitoring and control of entire power system. Phasor measurement units (PMU) are being deployed for real time monitoring and analysis of power system. The most important factor to be considered in placement problem is observability of power system with minimum number of PMUs. This paper proposed an Integer Linear Programming (ILP) b...
