DNA matching has become one of the most used biometric identification method during the last several years. DNA stores the information for creating and organizing an organism. It can be thought of as a string over the alphabets {A, C, G, T, N}, which makes four chemical components that make it up. Here, N represents an unknown nucleotide. This unknown(More)
In emitter geo-location estimation systems, it is well known that the geometry between sensors and the emitter can seriously impact the accuracy of the location estimate. Here we consider a case where a set of sensors is tasked to perform a sequence of location estimates on an emitter as the sensors progress throughout their trajectories. The goal is to(More)
This article introduces a new DNA sequence compression algorithm which is based on LUT and LZ77 algorithm. Combined a LUT-based preceding routine and LZ77 compression routine, this algorithm can approach a compression ratio of 1.9 bits/base and even lower. The biggest advantage of this algorithm is fast execution, small memory occupation and easy(More)
—When trying to estimate the location of a non-cooperative non-coherent emitter using intercepted signal measurements from a single airborne platform, the doppler-based techniques, such as the Frequency of Arrival (FOA) is not applicable. In this paper, we propose a single platform long baseline interferometry (LBI) based emitter location estimator which(More)
In this paper, we propose a fast 2-D block-based motion estimation algorithm called Particle Swarm Optimization Zero motion Prejudgment(PSO-ZMP) which consists of three sequential routines: 1)Zero-motion prejudgment. The routine aims at finding static macroblocks(MB) which do not need to perform remaining search thus reduces the computational cost;(More)
Time-of-flight (TOF) information improves the signal-to-noise ratio in positron emission tomography (PET). The computation cost in processing TOF-PET sinograms is substantially higher than for nonTOF data because the data in each line of response is divided among multiple TOF bins. This additional cost has motivated research into methods for rebinning TOF(More)
OBJECTIVES To facilitate the diagnosis, treatment and surgical options for congenital bony atresia of external auditory canal (EAC) with temporal-mandibular joint (TMJ) retroposition by analyzing its audiological features and the morphology of temporal bone on CT scan. MATERIALS AND METHODS Two cohorts of patients with congenital EAC bony atresia with(More)
