The non-orthogonal multiple access (NOMA) technique or more generally the non-orthogonal principle is a crucial component for the next generation cellular system. For two-user downlink NOMA, the constellations of near and far users are superposed for transmission, and maximum likelihood (ML) or successive interference cancellation (SIC) receiver is used for reception. In this paper, we aim to further...
A bend-resistant large mode area fiber with combination structure of multi-trench and leakage channel is proposed. In terms of the practical requirement for active fibers, the core region is designed with a higher refractive index than the pure silica, which allows the core to be highly doped with gain medium. In the meantime, a ring of high-index rods are introduced to work as the resonant ring,...
As renewable energy resources such as wind become more prolific, the challenges in utilizing these resources to their full efficiency come to the forefront of power system engineers. Although the sustainability of such alternative energy resources is attractive, the ability to obtain satisfactory efficiency has been difficult until recent advances in nonlinear control technologies. The subject of...
This paper deals with image categorization from weak supervision, e.g. global image labels. We propose to improve the region selection performed in latent variable models such as Latent Support Vector Machine (LSVM) by leveraging human eye movement features collected from an eye-tracker device. We introduce a new model, Gaze Latent Support Vector Machine (G-LSVM), whose region selection during training...
The modified global harmony search algorithm (MGHS) is designed to solve the shortest path problem. The dynamic gene mutation rate is defined to add into harmony search algorithm to avoid producing local optimal solutions. The path is constructed based on priority value of corresponding node in harmony vector with dynamic priority value encoding rule, and the shortest path is obtained by updating...
Considering the locality feature of voltage control problems, This paper proposes a coordinated voltage control method with tiered weight coefficients of optimization targets, the optimization problem is formulated and solved based on the model predictive control method. At the initial control time, the correlation degree between buses is obtained based on the dynamic voltage response feature and...
New control methods are presented in this paper for a hopping single-legged robot in the 2D plane. It is aimed to keep the robot's movement stably, namely kinematic parameters oscillating in a small range. Body angle, hopping height and horizontal velocity respectively represent the control parameters of three degrees of freedom. Finally, a series of simulation experiments show that all the kinematic...
Solar photovoltaic system maybe underperformanned because of too much dust, dirt and bird droppings, etc. 3D mapping for the cleaning robot still remains challenging in this large scale scenario. This paper presents a robust mapping system with Kinect V2 for automated photovoltaic cleaning system. Firstly, Kinect V2 is well-calibrated for a remedy to the production variety and the approach is fast...
The study bases on the peculiarity of the emergency events in the college life and the particular characters of the college students. We carry out the study by using the suitable new, which can induce emotion and the suitable respondent. The study divides into three parts. The first part is the study about the spread process of the emotion, we can get that the process developed in the order as “emotion...
Currently, the release of different chip products has come to a burst. Time-to-market period of these products has been shortened to an extreme, nearly 8 to 12 months. To reduce production period, hardware architects try to shorten every design and manufacture stage. Therefore, it has become one of the major concerns for them that how to accelerate electronic design automation (EDA) tools, which have...
In this work we present a novel and generic framework for reactive collision avoidance in bipedal locomotion, which is formulated as an optimization problem considering the constraints of collision avoidance as well as others (e.g. joint limits) to simultaneously satisfy both Cartesian and joint space objectives. To realize the reactive behaviors, several task space motions, such as the translational...
A low frequency (100 KHz∼1 MHz, mainly use in magnetic resonance wireless power transfer system ) permeability measurement method is designed and tested in this paper. In this method, a coaxial cavity and a low frequency band (30 KHz∼8 GHz) Vector Network Analyzer (VNA) are used as measurement equipment. Comparing the impedance change of coaxial cavity, with magnetic material in it or with air, we...
The hyperspectral remote sensing realizes image formation of spatial feature of the target by taking nanoscale super-high spectral resolution and meanwhile performs continuous spectral covering for dozens of and even hundreds of narrow wave bands formed on the wider wavelength range of each image element, which is with the ability of distinguishing the subtle difference of ground object spectrum,...
As the most abundant inland river of water resource in Liaoning province, Hun River affords industrial and agricultural production and domestic water task in central city group of Liaoning province. Recently, dozens of sewage draining exits in different sizes are constantly discharging along Hun River. Environmental monitoring communique can discover that indicators of ammonia nitrogen and COD are...
Full IP process in 4G wireless communication era has already made the synchronous digital hierarchy multi-service transfer platform (SDH/MSTP) no longer suitable for multi-service grooming mechanism. Packet transport network (PTN), which has not only almost the same advantages as MSTP in network construction, but has other characteristics like cost-effective as well, is been recognized as the most...
In view of old-fashioned digital display instrument of substation, an improved character recognition method for digital display instrument is proposed. It is a method mainly based on pulse coupled neural network which comes from study of cat's visual cortex neurons. Apart from synchronous oscillation that is one characteristic of pulse coupled neural network being used in image segmentation, the other...
As a classical ARMA modeling strategy, time series analysis is used widely. But when the model order is high, the computational complexity will be very large. Dynamic??data system can decrease the computational complexity by predigesting two-dimension order searching to one-dimension, but there are some problems, such as complexity of parameter estimate and artificial uncertainty. A modeling strategy...
In this paper, we present an integrated approach of multiple algorithms for visual localization and object tracking. First, a spatial point monocular vision range model is established.
