Lateral flow immunoassay (LFIA) is widely utilized in a variety of point-of-care-test (POCT) applications. In this paper, we discuss the development of an ASIC based strip reader controller for LFIA. The control algorithm was proposed and implemented in Verilog HDL and fabricated into ASIC with 0.18 μm CMOS technology. Functional validation on both FPGA and ASIC implementations were presented. The...
Based on the intra-body communication by galvanic coupling, this paper aimed to explore the impact on the signal transmission in the human body when the muscles were under the stress, and investigated the channel characteristics of different transmission distance and different grip size of the human arm. The results showed that, in the short-distance channel, the stressed muscles hindered the signal...
Human Body Communication (HBC), which utilizes the human body as communication channel to convey health informatics, is a prospective communication technique for implantable and surface-mounted medical devices. In this article, we have applied Shannon's theorem to derive the channel capacity for the general galvanic coupling HBC channel. The channel characteristics and channel model of general galvanic...
System event logs have been frequently used as a valuable resource in data-driven approaches to enhance system health and stability. A typical procedure in system log analytics is to first parse unstructured logs, and then apply data analysis on the resulting structured data. Previous work on parsing system event logs focused on offline, batch processing of raw log files. But increasingly, applications...
Recently, sparse representation has been widely used in localization and bearing estimation. The basic idea of the general sparse direction-of-arrival (DOA) estimation method is to divide the space into discrete grids. But the transmission signal's DOA doesn't always fall on the discrete network. This paper reformulates the above problem by exploiting the sparsity representation based on the modified...

An oceanographic research vessel is a special vessel designed to conduct research at sea on relevant natural elements and characteristics of the ocean and acquire its basic parameters with professional researchers and specialized equipment on board. It features an integration of the ship platform, research equipment and professional researchers. It is estimated that our country owns at least 50 oceanographic...
China has carried out five massive investigation and selection work on tidal energy and the latest survey results show that China's theoretical potentiality of the tidal energy within 10m depth contour offshore is estimated to be 192.86 GW. 171 potetial sites that have over 500 kW installed capacity add up to 22.83GW in total, with an annual energy output of 62.6 TWh. These potential sites of large...
Following the successful operation of tidal range power plants, such as 240 MW Rance Tidal Power Station in France and the 254 MW Sihwa Lake Tidal Power Station in South Korea, it has proven its technical viability and can be considered a mature technology. However, the assessment technique for tidal energy resources is not perfect. This paper summarizes the main problems of current tidal energy resource...
Nearshore wave model was established based on the enhanced Boussinesq equations, which were dispersed into orthogonal grids on spatial distribution and solved using alternating direction implicit (ADI) algorithm. There are three kind of boundary conditions which are absorbing boundary, reflecting boundary and wave-generating boundary in the model, while the wave on open boundary was driven by the...
The South China Sea (SCS) is a marginal sea of the western Pacific Ocean, encompassing a large area over 3.5 million km2. It is characterized by warm tropical and subtropical water with the surface temperature around 24–30 D°C throughout the year, which makes it a suitable region for the Ocean Thermal Energy Conversion (OTEC). However, the estimates of this new type of renewable energy in the SCS...

In this paper, adaptive rate random binning code is developed for point-to-point (P2P) delay constrained source streaming. We study the error exponent, which measures the asymptotic rate at which the error probability decays with delay. An achievable lower bound of error exponent is derived. Numerical results show that the proposed adaptive rate random binning code achieves a better exponent than...

This paper addresses the problem of state feedback control for a class of stochastic high-order feedforward nonlinear systems with multiple time-varying delays. A distinct property of the system to be investigated is that the control coefficients are not restricted to 1. By introducing the sign function and the adding one power integrator, a delay-independent state feedback controller is constructed...
