Deep embeddings answer one simple question: How similar are two images? Learning these embeddings is the bedrock of verification, zero-shot learning, and visual search. The most prominent approaches optimize a deep convolutional network with a suitable loss function, such as contrastive loss or triplet loss. While a rich line of work focuses solely on the loss functions, we show in this paper that...
In order to extend the life of the Solid Oxide Fuel Cell system and maximize the performance of the stack, it is very important to study the fault diagnosis method of SOFC system.

At last, this paper introduce a method which uses the fault tree method to diagnose the external system...
A novel N-JFET structure, combined with an innovative control gate between the uniform P-top and source is proposed. Control gate has a heavily doped P-type and a gap to uniform P-top. Pinch-off voltage of the JFET device can be easily adjusted by the size of the gap, while the breakdown voltage can be kept in the range of 700V ∼ 800V. Rather than using 3D simulation which is more time consuming,...
Peach is one of the most important commodities in the global fresh product market. With the development of people's living standard, consumers pay more attention to the internal quality of fruits than the appearance quality of fruits. The requirement of nondestructive analysis could be satisfied by near infrared (NIR) spectroscopy with appropriate data analysis methods. In this paper, we measured...
Private data is used on daily basis by a variety of applications where machine learning algorithms predict our shopping patterns and movie preferences among other things. Principal component analysis (PCA) is a widely used method to reduce the dimensionality of data. Reducing the data dimension is essential for data visualization, preventing overfitting and resisting reconstruction attacks. In this...
This work deals with beamforming for the MIMO Interfering Broadcast Channel (IBC), i.e. the Multi-Input MultiOutput (MIMO) Multi-User Multi-Cell downlink (DL). The novel beamformers are here optimized for the Expected Weighted Sum Rate (EWSR) for the case of Partial Channel State Information at the Transmitters (CSIT). Gaussian (Posterior) partial CSIT can optimally combine channel estimate and channel...
The Interfering Broadcast Channel (IBC) applies to the downlink of (cellular and/or heterogeneous) multi-cell networks, which are limited by multi-user (MU) interference. The interference alignment (IA) concept has shown that interference does not need to be inevitable. In particular spatial IA in the MIMO IBC allows for low latency transmission. However, IA requires perfect and typically global Channel...
Ambient energy harvesting has emerged as a promising technique to improve the energy efficiency and reduce the total greenhouse gas emissions for green relay networks. In this paper, we study the joint relay selection and power control problem for the Decode-and-Forward energy-harvesting wireless relay network. In particular, the problem formulation is to maximize the end-to-end system throughput...
With device-to-device (D2D) communications, a user terminal (UT) can be used as a relay node to support multi-hop transmission so that cell-edge or deeply faded users can obtain a better connective experience. In this paper, we investigate energy-efficient transmission for D2D-enabled cooperative networks. We aim to maximize the energy efficiency (EE) of the uplink transmission while guaranteeing...
This paper aims to explore the neural patterns between Chinese and Germans for electroencephalogram (EEG)-based emotion recognition. Both Chinese and German subjects, wearing electrode caps, watched video stimuli that triggered positive, neutral, and negative emotions. Two emotion classifiers are trained on Chinese EEG data and German EEG data, respectively. The experiment results indicate that: a)...
In this work, a trench power MOSFET (UMOS) with vertical RESURF is investigated. And the influence of some key parameters on UMOS static performances are simulated and analyzed by TCAD-Process. The proposed RESURF conventional trench gate UMOS is able to achieve better UIS performance while maintaining a specific low on state-resistance with breakdown voltage over 100 Volts. Here we are proposing...
The limited backhaul capacity has been considered as an important issue that influences the performance of traffic offloading in small-cell networks. We thus investigate how mobile users (MUs) efficiently offload traffic to different small cells with the new paradigm of dual-connectivity, subject to different backhaul capacities of small cells. Specifically, we formulate an optimization problem that...

A 600–800 V, BCD technology platform is presented in ultra-high voltage applications. An innovative feature is that all the devices have been realized by using a fully implanted technology in a p-type single crystal without an epitaxial or a buried layer. Ultra-high voltage triple RESURF LDMOS with the breakdown voltage up to 600–800V as well as low voltage CMOS and BJT have been achieved using this...
Apple plays an important role in modern agricultural economic.

This paper proposes an estimation scheme for three-dimensional (3-D) object positioning from monocular image .brightnesses without point correspondences while previous 3-D positioning methods need point correspondences. In the present scheme, at the first step, 3-D shapes of object are recovered from image brightnesses before and after rotation motion. At the second step, two vectors which are transformed...
