This paper reports a 3.0 THz detector which can detect the terahertz wave radiated by a quantum cascade laser (QCL) working at pulse mode. The detector was implemented in a 65 nm silicon CMOS process. The chip size is 1.5×l.5 mm2 including bonding pads. THz detector using FET is based on plasma wave theory proposed by Dyakonov and Shur which allows detection of THz radiations far beyond the FET devices...
In biomedical research, events revealing complex relations between entities play an important role. Event trigger identification is a crucial and prerequisite step in the pipeline process of biomedical event extraction. There exist two main problems in the previous work: (1) Traditional feature-based methods often rely on human ingenuity, which is a time-consuming process. Though most representation-based...
Genomic selection (GS) is a marker-assisted selection approach to enhance quantitative traits in breeding population in which whole genome single-nucleotide polymorphisms (SNPs) markers can be used to predict breeding values (BV). GS has been proved to increase breeding efficiency in both plant and animal breeding, such as dairy cattle, pig, rice, soybean and loblolly pine. Here, we propose a deep-learning...
We demonstrate a technique that enables three-fold enhancement of time delay and seamless delay switching for RF signals at gigahertz speed from optical ring resonators on an integrated Si3N4 chip, solely by optical power control.
A true-time-delay(TTD) element is demonstrated using on-chip stimulated Brillouin scattering. Record net-Brillouin-gain of 47dB enabled 4ns delay over 100MHz and phase-shift of ∼200°. The TTD element was validated by incorporating it in a two-tap filter.
We present an integrated RF photonic notch filter on a Si3N4 chip, with tunable bandwidth (150–300 MHz), high rejection (>50 dB), tuning range of 1–12GHz and negligible RF insertion loss, using resonators' unique phase responses.
Indirect rotor field oriented control (IRFOC) plays an important role in the high performance induction machine drives. In the indirect rotor field oriented control — based induction machine adjustable speed control system, the rotor field angle is usually obtained by the rotor angular velocity and the slip angular velocity. The rotor angular velocity can be sensed by an encoder with sufficient accuracy...
Aiming at the situation that the cable trench of the pumped storage power station is easy to be struck by lightning, using ATP-EMTP electromagnetic simulation software, established high-voltage cable and secondary cable distributed parameter model, focus on the analysis of lightning strikes the high-voltage cables in the cable trenches, the electromagnetic coupling between the high-voltage cable core...
Loop invariant generation is a fundamental problem in program analysis and verification. In this work, we propose a new approach to automatically constructing inductive loop invariants. The key idea is to aggressively squeeze an inductive invariant based on Craig interpolants between forward and backward reachability analysis. We have evaluated our approach by a set of loop benchmarks, and experimental...
In this paper, finite-time synchronization for delayed complex-valued bidirectional associative memory (BAM) neural networks is investigated. Based on the finite-time stability and some inequality techniques, a synchronization criterion is provided to guarantee that the drive-response systems achieve synchronization in finite time, and the settling time can be estimated effectively. Meanwhile, a suitable...
This paper addresses the problem of jointly recognizing object fluents and tasks in egocentric videos. Fluents are the changeable attributes of objects. Tasks are goal-oriented human activities which interact with objects and aim to change some attributes of the objects. The process of executing a task is a process to change the object fluents over time. We propose a hierarchical model to represent...
In this paper, we propose an approach to detecting project-specific recurring designs in code base and abstracting them into design templates as reuse opportunities. The mined templates allow programmers to make further customization for generating new code. The generated code involves the code skeleton of recurring design as well as the semi-implemented code bodies annotated with comments to remind...
To better assess the effectivity of UHF-PD sensor/system, two types of assessment procedures were established-the simple procedure and the complicated procedure. Both procedure required GTEM-Cell system and Simulation GIS/GIL. The element structure, the diagram and the signal transmission path of GTEM-Cell system and the Simulation GIS/GIL were demonstrated. The result data indicated that the discernment...
Resonant wireless power transmission has the advantages of long transmission distance and high efficiency. Series — series (SS) transmitting and receiving system is suitable for small load research. In this paper SS-type circuit is analyzed and discussed by using equivalent circuit theory. The mathematical models of the transmission efficiency and output power are derived. The influencing factors,...
We present a microwave photonic notch filter based on a Si3N4 photonic chip, with a noise figure of less than 20 dB, a positive link gain and an ultra-deep rejection beyond 50 dB in the stopband. This level of performance is achieved by using on-chip resonators' unique phase responses, and thorough optimizations of the photonic link.
A decentralized connective stabilization control problem employing reduced-order observers is solved for complexity large-scale systems with expanding construction. Without changing the original decentralized control laws, a decentralized controller is designed for the resulting expanded system so that the new subsystem added to the original one and the expanding system are robustly connective stable...
Robust state estimation of a discrete time-varying uncertain system is investigated in this paper when there are not only process and measurement noise, but also parameter uncertainties which affect a state-space model arbitrarily. The expectation minimization based robust state estimation is generalized to uncertain linear systems with a known deterministic input signal. The derived robust estimator...
In this paper, sampled-data control is considered for the attitude control of nonlinear spacecraft control systems. We mainly study a linearized spacecraft model i.e. the linearized inertial pointing spacecraft model. Moreover, it is shown that designed controller globally stabilizes the nonlinear space-craft system, and locally optimizes the spacecraft performances. The simulation results demonstrate...
This paper investigates the dynamics of evolutionary networked games with different length information via semitensor product (STP) method. First, a networked game with different length information is modeled by a probabilistic Boolean network (PBN) with time delays. Second, a control networked game is considered and its algebraic form is given. Finally, an example is presented to substantiate the...
Antimonene is a new 2D material and its applications in gas sensors are still deficient. We took a first principles investigation of three small organic molecules (formaldehyde, acetone, and methane) adsorption on the antimonene. We found that only the adsorption of the acetone molecule could induce a moderate adsorption energy, obvious charge transfer, and large work function change, which are suitable...
