Purpose
To estimate the national and provincial estimates of incidence, mortality and burden of skin cancer in Iran from 1990 to 2016.
Methods
The data for incidence and mortality rates were collected from the National and Subnational Burden of Diseases (NASBOD) project. We employed a two‐stage spatiotemporal model to estimate cancer incidence based on sex, age, province and year. The national...
Both safety and non-safety applications of vehicular networks rely on accurate position information. However, accurate localization of a vehicle in a global navigation satellite system (GNSS) denied environment is a challenging and still open research problem. The 802.11p dedicated short-range communication systems (DSRC), designed for vehicle-to-vehicle and vehicle-to-infrastructure communications,...
We propose a method for tracking a moving receiver using RF messages broadcasted from opportunistic beacons. The beacons are not required to be synchronized with each other or with the receiver. By measuring the time-of- arrival (TOA) of the RF messages transmitted from the beacons at different locations along the receiver's trajectory, the receiver is able to track its own location, velocity and...
We propose a novel technique to localize a periodic transmitter using a single mobile receiver. By having the receiver measure the time-of-arrival (TOA) of the periodic messages sent by the transmitter, the receiver is able to measure the virtual time-difference-of-arrival (V-TDOA) between different locations along its trajectory. The V-TDOA can then be used in place of TDOA measurements in various...
In this paper we propose a method to localize a periodic RF transmitter using a single mobile receiver. The receiver measures the time-of-arrival (TOA) of the periodic messages at different locations along its trajectory. By comparing the TOA of successive messages at different points along its trajectory, the receiver can eventually estimate the transmitter location. The challenge lies in separating...
This paper considers the problem of tracking an acoustic sources in three dimensional (3-D) space by using a vertical acoustic vector sensor (AVS) array in a shallow ocean environment. The innovations of this work are double fold: 1) a particle filtering (PF) approach is developed to track the position of an acoustic source; and 2) based on the source motion and wave propagation models, the posterior...
This paper presents a computationally efficient method of 3-D localization of underwater acoustic sources in heavy-tailed non-Gaussian noise by an acoustic vector sensor (AVS) array. Noise is modeled as a Gaussian mixture. Estimation of source coordinates, signal waveform and noise parameters is based on the space-alternating generalized EM (SAGE) algorithm. This method requires one 2-D search and...
