This paper presents an improved one-layer projection neural network for solving the linear assignment problem. The assignment problem is first converted into a linear programming problem, then a corresponding recurrent neural network is constructed. The optimality and global convergence of the proposed neural network are analysed and proved. Compared with existing neural networks for linear assignment...
The present work describes the study and improvement of heterogeneous integration based on epitaxial layer transfer technique, which is used to separate III/V device from their substrate and transfer to the other substrate. Our work aims in the development of a new process for integration of GaAs device with Silicon substrate. It is based on low temperature bonding of the epitaxial layer transfer...
A short channel normally-off static induction transistor (SIT) for low power applications is designed. Research about this SIT's performance such as I-V characteristics, gate-source breakdown, gate-drain breakdown et al. is achieved by numerical simulation. Process parameters and structural parameters of SIT are optimized based on the simulation results. After tape-out we conduct the SIT's performance...
A design method is proposed for obtaining high gate control efficiency SIT with surface-gate structure for low power Applications. In this paper a high performance SIT with comparatively large voltage amplification factor was manufactured and tested. Based on simulation and calculation, voltage amplification factor depends on not only the aspect ratio of the channel but also the impurity distribution...
This paper presents a monolithically integrated 2×4 coherent source array operating at 0.54–0.55 Tera-Hertz (THz) in 65nm digital CMOS technology. The source array contains 20 oscillating elements which can radiate in-phase THz signal via each of their own differential slot ring antennas. Each of the oscillating elements is made of a triple-pushed Colpitts voltage controlled oscillator (TPCVCO). Among...
We developed a novel copper-bondable silver paste for the pressureless bonding of large-area chip on bare copper substrate. This paste includes silver nanoparticles, silver sub-micron-sized flakes, and organics. The finally densification, which is controlled by grain boundary and lattice diffusions, was developed by the formation of robust solid necks among the nanoparticles and flakes. The sintered...
The noise performance of an all-digital phase-locked loop (ADPLL) is limited by the resolution of the time-to-digital converter (TDC). Most TDC research in the past focused on the arrival time difference between the edges of the divider feedback and the reference signal [1-2]. This results in coarser TDC resolution and worse ADPLL noise performance. This paper presents a fractional-/VADPLL that employs...
Contactless (3D) touch sensors, when integrated with displays, offer many advantages over that of conventional touch-panel screens by offering a more hygienic and a more immersive & interactive human/machine interface for 3D user experiences [1]. While significant progress has been made in developing 3D contactless touch sensors for larger television and monitor type displays [2-3], the technology...
The problem of detecting a subspace signal is studied in colored Gaussian noise with an unknown covariance matrix. In the subspace model, the target signal belongs to a known subspace, but with unknown coordinates. We first present a new derivation of the Rao test based on the subspace model, and then propose a modified Rao test (MRT) by introducing a tunable parameter. The MRT is more general, which...
The tracking loop is an important part of GPS receiver, and its performance has great influence upon the receiver. So the tracking performance of tracking loop is underlined in this paper. To improve the performance of traditional tracking loop, three typical structures of Kalman filter based tracking loops are investigated, which are carrier and code combined Kalman filtering loop, carrier and code...
In order to determine the viewing distance with low complexity and high transportability, a measurement method using a single camera is proposed in this paper. After the image of the face of the viewer is taken by a single camera, it is input to the preprocessing component and the resolution of the image is transformed into a given resolution for fitting function. The pixel distance between binocular...
Automatic identification of HEp-2 cell images has received an increasing research attention. Feature representations play a critical role in achieving good identification performance. Much recent work has focused on supervised feature learning. Typical methods consist of BoW model (based on hand-crafted features) and deep learning model (learning hierarchical features). However, these labels used...
Limiting short circuit current and increasing power system stability is a contradiction. An optimization and decision model for limiting short circuit current considering sensitivity ranking is established. Firstly, the influence on impedance matrix caused by current limiting measures is analyzed, and a variable selection strategy considering the sensitivity relation between current limiting measures...
Dissolved Gas Analysis (DGA) has already gained its popularity in fault diagnosis for the oil-immersed transformers. However, owing to the fuzziness and uncertainty between the failure phenomena and failure mechanisms, power equipment failure reasons are very complicated and the accuracy of existing algorithms is low. Diagnostic methods based on artificial intelligence are commonly introduced in the...
Cost aggregation is the most important step in a local stereo matching algorithm. In this paper, a novel cost aggregation method based on Adaptive Shape Support Window (ASSW) is proposed. There are two main parts: At first we construct a local support skeleton anchored each pixel with four varying arm lengths decided on color similarity, as a result, the support window integral of multiple horizontal...
It is difficult to detect the target area of the image which has complex gray scale information in the field of industrial detection. So in order to improve the accuracy of detection, this paper proposed improved image segmentation method based on the region of interest. In the proposed method, the authors extracted regions of interest from the detected image that remove the effects of the complex...
Glass is a brittle and amorphous material. It can be used as the functional material for optics, electronics and semiconductor. However, it's difficult to machine glass with superior surface finish due to its high hardness and low fracture toughness. An experimental investigation was performed to identify the key factors governing the machining mode in micro-end-milling of glass. The results show...
Knowledge representation is a central problem in intelligent design, where there are a number of contradictory problems. In order to overcome the limitations of existing knowledge representation methods in processing contradictory problems, this paper proposes a novel scheme of knowledge representation based on basicelement in Extenics.
