Social influence has attracted tremendous attention from both academic and industrial communities due to the rapid development of online social networks. While most research has been focused on the direct influence between peers, learning cascaded indirect influence has not been previously studied. In this paper, we formulate the concept of cascade indirect influence based on the Independent Cascade...
As the most promising solution to sustain network capacity scaling beyond the fundamental nonlinear Shannon limits of standard single-mode fibers, space division multiplexing (SDM) has attracted enormous attention. To utilize the dimension of “space”, including mode-division multiplexing (MDM) using multi-mode (few-mode) fibers and core multiplexing using multi-core fibers, SDM can substantially increase...
Synthetic aperture radar (SAR) is traditionally developed to obtain high-resolution images. AS real-time SAR imaging is becoming more and more important, high speed radar signal processing method and high resolution of radar imaging technology are being widely studied. Optical processing provides inherent parallel computing, which can perform 2D Fourier transformation at the speed of light. It will...
In Cognitive Neuroscience, the sustained attention under disturbance condition has been a hot research topic. We not only study the basic mechanism of sustained attention, but also study how the disturbance affects the nervous system of sustained attention.
Aiming at the requirement of Doppler and channel estimation which applied to underwater mobile communication with orthogonal frequency division multiplexing (OFDM) technology, a PN sequence based method for Doppler and channel estimation is proposed, an underwater acoustic OFDM communication system structure is given and a block data frame based on PN sequence is designed. For the Doppler estimation...
Driven by ubiquitous cloud computing application, datacenters have been deployed widely as important IT resources. However, some disadvantages are challenging the cloud computing because the datacenters are deployed concentrated and remotely, which cannot guarantee the quality of experience (QoE) for the customers, such as the latency, bandwidth, energy consumption, and network cost. Fog computing...
A bent-tip optical angular displacement sensor was designed. The output function of the bent-tip fiber gained based on the bent-tip optical bundle structure analyzing. Effects of spacing p and angular α on receiving optical fiber bundle and the transmitting fiber was simulated, and the displacement h of transmitting fiber from reflect surface impact on the differential intensity is investigated. Sensor...
The achievements in underwater robotics and Wireless Sensor Networks make it possible to explore aquatic environment further. Target tracking which combines the mobility of underwater robotics with sensor networks has become an important application area in aquatic environment. This paper employs a Robotic Fish-based Sensor Network (RFSN) as mobile sensing platform to realize the target tracking....
During the last ten years, the progress of the Internet of Things (IoT) has continued unabated and gradually expanded into almost every corner of our daily lives. One very typical use case of IoT is the intelligent building (IB). Along with the remarkable rise of IoT, an increasing number of smart devices will be connected to IB networks, which brings many challenges to current IB network architectures...
Code virtualization built upon virtual machine (VM) technologies is emerging as a viable method for implementing code obfuscation to protect programs against unauthorized analysis. State-of-the-art VM-based protection approaches use a fixed scheduling structure where the program follows a single, static execution path for the same input. Such approaches, however, are vulnerable to certain scenarios...
Non-Volatile Memory Express (NVMe) is designed with the goal of unlocking the potential of low-latency, randomaccess, memory-based storage devices. Specifically, NVMe employs various rich communication and queuing mechanism that can ideally schedule four billion I/O instructions for a single storage device. To explore NVMe with assorted user scenarios, we model diverse interface-level design parameters...
As The integration of Physical space and cyberspace, the large-scale data distributing to diversification terminal which is geographical distribution of mass has become a huge challenge. When the data size can't be processed by the technology for traditional scope, how to deal with the user quality of service and efficient use of system resources has become an important issue of concern, with the...
The TanDEM-X constellation is served by two X-band SAR satellites, which fly in close orbit formation acting as a large and flexible single-pass radar interferometer. This paper investigates the potentials for monitoring sea ice in the Bohai Sea with the unique constellation. Our results show that the coherence and interferometric phase of TanDEM-X data can be used to detect sea ice, and the radial...
The frequent occurrences of drought in the Great Plains of United States have led to significant crop loss. Timely monitoring of drought-induced agricultural impacts, especially at a large scale from remote sensing, is of great importance for ensuring food security. Following the authors' prior drought impact work in Kansas, based on MODIS data, this study investigated the impacts of drought on winter...
Student motivation is one of the most important individual characters for explaining student performance in class. Existing researches show that it can be affected largely by social-contextual factors. Rather than focusing on social relationship, in this paper we construct social activity networks for analyzing the impact of collective behaviors on student motivation. We conduct field experiments...
In this paper we propose a novel approach to deal with synchronization of networked Euler-Lagrange systems separating local controller design from topology graphs. A specified consensus network is first constructed, where many existing consensus algorithms regardless of our node dynamics can be used. Subsequently, each Euler-Lagrange system is driven by a local controller designed together with the...
Spatial multiplexing (SM) gains in multiple input multiple output (MIMO) cellular networks are limited when used in combination with ultra-dense small cell networks. This limitation is due to large spatial correlation among channel pairs. More specifically, it is due to i) line-of-sight (LOS) communication between user equipment (UE) and base station (BS) and ii) insufficient spacing between antenna...
As mobile devices grew rapidly over the past few years, the wireless data demand has increased exponentially. Due to the extremely high price of licensed spectrum, License Assisted Access (LAA) has been proposed to provide high capacity by extending LTE transmissions to the unlicensed spectrum that WiFi systems operate. Due to the coexistence with WiFi systems, mobility management has become a critical...
The convergence analysis of two-dimensional based integrated predictive iterative learning control (2D-IPILC) is presented for batch process in presence of output noises. In the 2D-IPILC method, iterative learning control (ILC) in the batch domain is integrated reasonably with real-time model predictive control (MPC) in the time domain. Based on the 2D system theory, system response of output tracking...
Alzheimer's disease (AD) is a progressive brain disease. Accurate diagnosis of AD and its prodromal stage, mild cognitive impairment, is crucial for clinical trial design. There is also growing interests in identifying brain imaging biomarkers that help evaluate AD risk presymptomatically. Here, we applied a recently developed multivariate tensor-based morphometry (mTBM) method to extract features...
