Social media offer abundant information for studying people's behaviors, emotions and opinions during the evolution of various rare events such as natural disasters. It is useful to analyze the correlation between social media and human-affected events. This study uses Hurricane Sandy 2012 related Twitter text data to conduct information extraction and text classification. Considering that the original...
An accurate marching-on-in-degree (MOD) scheme is proposed to solve the time-domain integral equation (TDIE) integrated with the modified nodal analysis (MNA) for simulating transient field-circuit coupling problems. In the MOD scheme, a set of weighted Laguerre polynomials is chosen as the temporal basis functions. Besides, the current continuity equation is modified for connecting the electromagnetic...
Microrobots have great potential for microassembly and non-invasive surgery applications. Motivated by studies proposing MRI-guided drug delivery to tumor cells using magnetic micro carriers, this paper studies two major challenges of this problem: (i) microrobot swarm trajectory generation, and (ii) swarm aggregation using a global input. We propose an augmented RRT for trajectory generation to reduce...
Here we demonstrate self-aligned bi-layer metallic metasurfaces that accomplish dual and broadband terahertz antireflection. Numerical simulations and experimental measurements show that excellent antireflection performance can be achieved by simply tailoring the geometry of the subwavelength structures. This flexible antireflection scheme can be applied to substrates with arbitrary refractive indices...
This paper is concerned with finite-time synchronization for two models of coupled Cohen-Grossberg neural networks with time-varying delays. In the first one, linearly coupled Cohen-Grossberg neural networks is considered. In the second one, nonlinearly coupled Cohen-Grossberg neural networks is discussed. Based on finite-time stability theory, some inequality techniques, and designed controllers,...
Software development for Cyber-Physical Systems (CPS), e.g., autonomous vehicles, requires both functional and non-functional quality assurance to guarantee that the CPS operates safely and effectively. EAST-ADL is a domain specific architectural language dedicated to safety-critical automotive embedded system design. We have previously modified EAST-ADL to include energy constraints and transformed...
Modeling and analysis of non–functional properties is crucial in energy-aware real-time (ERT) automotive systems. EAST-ADL is an architectural language dedicated to safety critical automotive embedded system design. We have previously modified EAST-ADL to include energy constraints and transformed ERT behaviors modeled in EAST-ADL/STATEFLOW into UPPAAL models amenable to formal verification. Previous...
Controlling microrobots in the past have required the used of heavy coil systems and large power supply units, in this paper we show that a strong permanent magnet is sufficient for the control scheme. The development of a controlling stage was deemed to be a priority and allowed for the manipulation of microrobots, otherwise known as alginate particles or artificial cells, in the xy-plane. We show...
The problem of passivity is discussed in this paper for reaction-diffusion Cohen-Grossberg neural networks (CGNNs) with multiple time-varying delays. By constructing suitable lyapunov functionals and employing some inequality techniques, several sufficient conditions guaranteeing the passivity of CGNNs are obtained. Furthermore, several criteria for robust passivity are also derived for the case that...
This paper investigates the synchronization problem of nonlinearly coupled reaction-diffusion neural networks (NCRDNNs). By utilizing Lyapunov functional combined with several inequality techniques, a criterion for synchronization of NCRDNNs is presented. With designed pinning scheme, the synchronization problem of NCRDNNs is further discussed and a sufficient condition for pinning synchronization...
UHF sensor plays a very important role in UHF method. In order to overcome the shortcomings of the external GIS partial discharge (PD) detection sensor, a small quasi TEM horn antenna sensor is designed in this study. Compared with the traditional TEM horn antenna, it uses the dielectric-loading, three-dimensional microstrip and back cavity structure considering the bandwidth and gain performance,...
Generally, we can speed up fault location procedures and reduce the recovery time via installing telecontrolled and automated sectionalizers in distribution networks. Besides, circuit breakers can also be installed in the network to reduce the average number of users' outages. However, the number of circuit breakers (CBs) is limited by the time selectivity. In smart grid perspective, the usage of...
Medical and health data are collected and stored in various document types and databases including clinical treatment records, medical examinations, prognosis health information, health billing and claims, health surveys, and community health settings. Such huge amount, wide range, and unstructured dataset characteristics imply a big challenge for researchers and government officers to analyze and...
Low-light camera is a special kind of detector which is capable of detecting weak signal down to a few photons or even single photon. Low-light camera is an essential element in super-resolution localization microscopy, because the latter requires detection of the weak fluorescence from single molecules. Currently, there are several types of widely-used low-light cameras which are commercially available...
Today, due to the popularity and convenience of wireless communications, people communicate with others by using mobile phones almost every day, as one of their important daily activities. Currently, LTE-4G is the mainstream of mobile communication. Recent studies on the upcoming LTE-5G wireless environments employ AES to protect delivered messages. However, using this cryptography standard to encrypt/decrypt...
In the previous work, an interactive real-time user interface (RTUI), which is a reliable human-in-the-loop framework that allows human users to dynamically modify the parameters of network model during the simulation process, is investigated. However, the delay overhead of parameter re-configuration commands transmission is unavoidable, especially for a great amount of parameters in a large scale...
The nematode Caenorhabditis elegans is widely used as a genetic model organism because of its relevance to human biology and disease. Quantifying C. elegans movement behavior is important for understanding the differences between genotypes under various food conditions. One of the most common ways to quantify C. elegans movement is through path analysis. However, comparing the movement paths between...
In order to find the change laws of human meridian and to prove the laws' consistency with Traditional Chinese Medicine theory, conductance series data of 72 acupoints from 10 volunteers was collected for 2 years. Visualized analysis method is used in this paper to find the laws, as it a good way to find change laws before there's a definite research target. As it is a tough job to collect data form...
Sub-health is a state between health and disease conditions, which is common among people living with the fierce competition and rapid pace of modern life. At present, there are no unified approaches to diagnose the sub-health patients. Self-reporting, the use of questionnaires, is one of the most popular approaches to evaluate health conditions. While a questionnaire consists of as many as 400 questions,...
Visualization of goods package has become an important factor in communicating goods characteristics to consumers and plays a critical role in influencing consumers' purchase decision. This phenomenon is particularly apparent in the case of mature consumer goods such as perfume products, chocolate, daily commodity, and so on. To construct a design support model for assisting package designers to create...
