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...
A multi-beam LiDAR scheme based on an integrated star coupler is proposed. The architecture allows for acquisition of multiple scanning directions within a single pulse repetition interval, enabling multi-target detection and tracking, thus combining the advantages of flash and scanning LiDAR.
We propose a compact on-chip fan-out for multicore fiber using a focusing grating coupler array realized on a single-etch silicon nitride platform. Coupling loss of 11 dB with a 3-dB bandwidth of 30 nm and channel crosstalk lower than 28 dB are demonstrated.
A 3D integrated hybrid silicon laser was demonstrated with tuning range of 30 nm, a side-mode suppression ratio of 34 dB, optical output power of 2 mW, and peak relative intensity noise of −135 dB/Hz.
A method of hybrid integration using grating couplers is demonstrated providing a way to utilized high speed InP photodetectors in silicon photonics. Responsivity measurements before and after bonding are reported to quantify coupling efficiency.
Expression recognition in the wild is a challenging task because of the interference of various environment. In this paper, we propose a transfer-learning method that utilize two representative transformations from grayscale images as input and fuse their results in decision level to enhance the overall performance, which also address the dimensional mismatch issue when applying pre-trained deep neural...
This study aims to design an adaptive output recurrent cerebellar model articulation controller (AORCMAC), which is embedded into the direct torque control (DTC) system of an induction motor as the speed controller. Similar to the conventional cerebellar model articulation controller (CMAC), the designed AORCMAC also has the advantages of rapid learning, simple architecture, online training, and nonlinear...
This paper investigates the type-2 T-S fuzzy multiple feedback-loop guaranteed cost controller design for uncertain singular systems with transmission and state delays. Based on the type-2 T-S fuzzy theory, this work constructs a mathematical model for a class of nonlinear uncertain singular time-delay systems. Using the parallel distributed compensation concept with Lyapunov theory and linear matrix...
Nowadays, the development of video coders is resulting in significantly increased performance. Among all coder categories, fine grain scalable video coders have the chance to show great advantage by freely extracting code-streams with different bitrates, resolutions, and frame rates from one source-coded bit file to satisfy the various requirements of subscribers in a multicast network. Based on the...
An optical ring resonator (ORR) based 1 × 4 integrated optical beamforming network (OBFN) targeting mmW is reported. The optimized true time delay response of a 3-ORR delay line with a bandwidth of 8.7 GHz was achieved over tuning range of 172.4 ps, which corresponds to a 31π phase shift for a 90 GHz signal. A 3 Gbps OOK NRZ data signal was transmitted through the delay line to verify the overall...
This paper studies an uplink simultaneous wireless information and power transfer (SWIPT) system with non-orthogonal multiple access (NOMA), consisting of two users and one energy-harvesting access point (AP). The users transmit their independent information simultaneously to the AP which harvests energy and decodes information at the same time by dynamic power splitting (DPS). We focus on the ergodic...

In order to solve the problem that the accuracy of flaws identification in ultrasonic testing is not high enough due to the error in sensor information acquisition and the noise interference in the detection environment, a method of flaws identification in ultrasonic testing based on evidential reasoning rule (ER rule) is studied. Firstly, ER rule is proposed to consider the reliability and weights...
The microfluidic fluorescence detection system's strengths are high sensitivity and easy operability, nevertheless it may also be more vulnerable to electronic circuit, ambient light, quenching effect which can influence the quality of the signal detection by adding noise. In order to improve the efficiency of the fluorescence detection system, eliminating noises from the signal is a significant step...
Internet of Things (loT) is network connected “Things” such as vehicles, buildings, embedded systems, sensors, as well as people.

Due to the large...
In this paper a new model is proposed to schedule the capacity of both up and down spinning reserve (SR) considering transmission constraints. Up SR is seen as the most important resource to cope with many contingencies and it is well studied, while the down SR is ignored by many papers especially when network constraints are considered. Ignoring the down SR would cause sub-optimal or even unfeasible...
Laser voltage imaging (LVI) and laser voltage probing (LVP) are laser stimulation techniques to verify a device under test (DUT) and have been widely used for scan chain circuit debugging and various frequency-dependent failure modes. In the case of complex logic failures in advanced technology nodes, defect localization continues to be a challenge in the failure analysis field. Dynamic electrical...

Applying the Meyer-Neldel Rule, the drain current model is developed. The model results are in agreement...
Low frequency noise behavior and hot carrier injection (HCI) effect in 65nm NMOSFET was investigated in this paper. The number of oxide traps and interface traps induced by HCI effect and traps density near silicon oxide interface before and after HCI test were calculated by low frequency noise technology. It was observed that the change during HCI test was determined by low frequency noise technology.
With the development of network technology and e-commerce, online-purchasing has become a fashion which takes a significant ratio of the whole market. Product reviews in e-market platform have a lot of information, and buyers tend to rely on the product'information and the reviews to determine the exactly quality of the product. However, the existence of fake reviews will mislead the consumers and...
