Cooperative tracking plays a key role in space situation awareness for scenarios with limited number of observations or poor performance single sensor both. To use the information from multiple networked sensors, both centralized and decentralized fusion algorithms can be used. Compared algorithms, are more robust terms communication failure computational burden. One popular distributed estimation approach is based on average consensus that asymptotically converges to estimate by exchanges...
An increase in mechanical load the heart causes cardiac hypertrophy, either physiologically (heart development, exercise and pregnancy) or pathologically (high blood pressure heart-valve regurgitation). Understanding hypertrophy is critical to comprehending mechanisms of development treatment disease. However, major molecular event that occurs during physiological pathological dynamic process sarcomeric addition, it has not been observed. In this study, a custom-built second harmonic...
This paper presents an Omnidirectional mobile target-node (TN) localization technique in nonline-of-sight (NLOS) scenarios. Here, a TN cooperates with base-nodes (BNs) antenna-arrays to allow them find its position via time-of-arrival (TOA) and direction-of-arrival (DOA) measurements. When line-of-sight (LOS) channel is available, each BN localizes TNs coverage area reasonable accuracy. However, when LOS obstructed, considerable error generated. To avoid NLOS error, proposed identify if the...
Abstract The scientific observation of gamma-ray bursts (GRBs) paves the way towards unveiling a novel perspective dynamic universe. In past few years, several nano-satellite (NanoSat) GRB missions were deployed, especially Gamma-Ray Integrated Detectors (GRID) Mission which is currently constructing constellation NanoSats with more than ten compact detectors. Owing to unpredictability time and location GRBs, angular response such detector one most important aspects for not only localization...
Abstract Both the NaIL scintillator and silicon photomultiplier (SiPM) are susceptible to temperature fluctuations, which could change characteristics of detected neutron gamma waveforms result in significant drift pulse shape discrimination (PSD) values with fixed PSD algorithm parameters, causing false alarms or missed alarms. This paper investigates a temperature-adaptive neutron-gamma using one-dimensional convolutional neural network (1D-CNN). can discriminate mixed data automatically...
To compare the long-term survival outcomes, recurrence patterns and morbidity of type B C radical hysterectomy (RH) for stage IB2 cervical cancer (FIGO 2018). Based on FOUR-C database, patients who underwent or RH in 47 hospitals from 2004 to 2018 were reviewed. Univariate multivariate analyses performed 5-year overall (OS) recurrence-free (RFS), between two groups after propensity score matching (PSM). A total 1308 enrolled this study, 840 468 C. There was no difference outcomes C, either...
A joint manifold learning fusion (JMLF) approach is proposed for nonlinear or mixed sensor modalities with large streams of data. The multimodal data are stacked to form manifolds, from which the embedded low intrinsic dimensionalities discovered moving targets. mapped resolve target locations. JMLF framework tested on digital imaging and remote sensing image generation scenes mid-wave infrared (WMIR) augmented distributed radio-frequency (RF) Doppler Eight methods explored train system...
Space object classification is desired for space situational awareness to be able discern resident (RSO) characteristics, behaviors, and perspective changes. Due the limited sensing resources observations, it challenging responsive unfolding unexpected events. Many machine learning algorithms are already used classify objects based on various sensor observations from radar telescope. In this paper, use of deep neural networks (DNN) proposed due DNN robust performance in many tasks, such as...

With the emergence of long lasting surveillance systems, e.g., full motion video (FMV) networks and wide area imagery (WAMI) sensors, extracting targets' term pattern life over a day becomes possible. In this paper, we present framework for (POL) targets from WAMI video. We first apply context-aware multi-target tracker (CAMT) to track multiple in obtain tracklets, traces, locations, information extracted long-term trajectories. Then, entity propagate time are constructed with interested...

Developments in video tracking have addressed various aspects such as target detection, accuracy, algorithm comparison, and implementation methods which are briefly reviewed. However, there other attributes of full motion (FMV) that require further investigation for situation awareness event activity analysis. Key behavior analysis include interaction between individuals, groups, crowds well with objects the environment like vehicles buildings over a specified time duration it is typically...
Image compression is an important component in modern imaging systems as the volume of raw data collected increasing. To reduce while collecting imagery useful for analysis, choosing appropriate image method desired. Lossless able to preserve all information, but it has limited reduction power. On other hand, lossy compression, which may result very high ratios, suffers from information loss. We model compression-induced loss terms National Imagery Interpretability Rating Scale or NIIRS....

This paper introduces a novel implementation of direction-of-arrival (DOA) estimation for localization nodes in (mobile) ad-hoc networks. The technique is being implemented on software defined radio (SDR) system. SDR system needs DOA for: (a) beam-forming and detection, (b) localization. detection process coarse estimation, while the fine one. fuses two known techniques: delay-and-sum root-MUSIC. former simple suitable on-line (high speed) required detection. Hence, it would consume less...
