Remote Ultra-Low Light Imaging detectors are photon limited detectors developed at Los Alamos National Laboratories. RULLI detectors provide a very high degree of temporal resolution for the arrival times of detected photoevents, but saturate at a photo-detection rate of about 10 photo-events per second. Rather than recording a conventional image, such as output by a charged coupled device (CCD...

This paper addresses the problem of tracking space-borne objects of interest (OoIs) with a satellite-assisted collaborative space surveillance network (SSN). It is formulated as a multiple moving-object tracking problem in a hybrid distributed wireless sensor network (WSN) made of both mobile and static nodes. The static nodes may be considered as ground-based sensors with fixed locations, whil...

We study the stochastic $p$-Laplace system in a bounded domain. propose two new space-time discretizations based on approximation of time-averaged values. establish linear convergence space and $1/2$ time. Additionally, we provide sampling algorithm to construct necessary random input an efficient way. The theoretical error analysis is complemented by numerical experiments.

Background: Sialic acid is a component of serum that is elevated in diseases such as diabetes and certain malignancies.  The normal range of SSA concentration and serum neuraminidase activity in different populations are varied, probably due to racial differences. Objective: The purpose of the present study was to obtain the average SSA concentration and serum neuraminidase activity, in an Iran...

The rheumatic disease autoantigen, Ro/SSA, was immunogenic to a rabbit host. The heteroimmune rabbit serum bound the Ro/SSA particle in immunoblots and in an ELISA. Both the rabbit anti-Ro/SSA and a human prototype anti-Ro/SSA serum also bound IgG; and moreover, IgG inhibited both rabbit and human anti-Ro/SSA activity. Anti-IgG activity of the rabbit and human anti-Ro/SSA sera bound Ro/SSA by W...

Space situational awareness (SSA) plays an important role in maintaining space advantages. Task planning is one of the key technologies SSA to allocate multiple tasks satellites, so that a satellite may be allocated supervise objects, and object supervised by satellites. This paper proposes hierarchical distributed task-planning framework for systems with focus on fast effective task customized...

Short-term traffic flow prediction is one of the most important issues in the field of intelligent transport system (ITS). Because of the uncertainty and nonlinearity, short-term traffic flow prediction is a challenging task. In order to improve the accuracy of short-time traffic flow prediction, a hybrid model (SSA-KELM) is proposed based on singular spectrum analysis (SSA) and kernel extreme ...

This review article deals with some effects of neck muscle proprioception on human balance, gait trajectory, subjective straight-ahead (SSA), and self-motion perception. These effects are easily observed during neck muscle vibration, a strong stimulus for the spindle primary afferent fibers. We first remind the early findings on human balance, gait trajectory, SSA, induced by limb, and neck mus...

This paper investigates possible autonomy architecture designs of a Raven-class telescope as applied to the tracking and high level characterization problem in Space Situational Awareness (SSA). Various levels of autonomy are defined and existing systems and capabilities are discussed. Telescope interactions with distributed sensor networks such as the Space Surveillance Network (SSN) are revie...
