Many scientific applications rely on the evaluation of elementary transcendental functions (e.g.~sin, cos, exp, log). Software math libraries are a popular approach for realizing such functions, and frequently use series expansion or lookup-table-based techniques. However, software approaches necessarily suffer from the traditional overheads of fetching/decoding instructions, limited cache sizes,...
with the development of industrialization and computer science and technology, people more and more attention to the intelligent industrial, big data applications in industry by leaps and bounds, artificial intelligence in various fields show their unique style. In this paper after the modern media from the perspective of Ideological and political culture to establish research study of artificial...
the optimization algorithm plays an important role in solving the complex problems, and many complex problems can be modeled as a combinatorial optimization problem. The multi-dimensional knapsack problem is a kind of typical combinatorial optimization problem. The pollination algorithm is a kind of natural heuristic algorithm proposed in recent years, which has the characteristics of few parameter...
In order to elevate equipment-oriented traditional asset management to system-oriented advanced asset management (AAM) decision-making for smart power grid, for the problem that influence of different positions of the equipment in network topology on system reliability is not taken into consideration in retiring strategies of transformer LCC (life cycle cost), which may cause overestimation or underestimation...
Free-piston Stirling power generating system is a complex coupling system of thermo-mechanical-electrical, the thermo-electrical efficiency of which is affected by many factors. The effect of critical parameters of core components on system efficiency is a main focus, including the regenerator porosity and the change of wire screen diameter on the effect of system, the regenerator changes of flow...
UAVs (Unmanned Aerial Vehicles) have been widely used in power line inspections, but low autonomous cruise capacity of UAVs requires strict condition for operators and site while landing during UAV power line inspections. This paper presents an autonomous landing control technique for UAVs when charging at the electric towers based on vision positioning method. The proposed system consists of three...
In order to realize autonomous landing of the unmanned aerial vehicle (UAV) in power patrolling, a visual method vision based on Faster Regions with Convolutional Neural Network (Faster R-CNN) for UAVs is studied. In this paper, we design the landing sign of the combination of concentric circles and pentagon, and propose the Faster R-CNN recognition algorithm which can be used to identify the target...
This paper presents an intelligent operation and maintenance training system for power grid operation staff of substation based on augmented reality (AR), whose functions, characteristics, software configuration and implementation are introduced in details. As the training and examination system for operation and maintenance personnel, the system was composed of intelligent training system and intelligent...
We propose a novel approach for safe tracking of a moving target in cluttered environments using a quadrotor. The key contribution of our work is a formulation that enables the generation of safe and dynamical feasible tracking trajectories that satisfy arbitrary relative motion patterns (circling, parallel tracking, undirectional tracking, etc.) with respect to the target. In our framework, forming...
This paper focuses on the influence of annealing process on the properties and microstructural evolution of through-silicon-via electroplating copper. Particular attention is paid to the interposer-related through-silicon-via applications, which is fabricated by via-last process with the diameter of 20 microns and above. A interposer was designed and fabricated with its diameter of 100 microns and...
This article presents a simple, non-toxic, and low-cost tips arrays made of poly-dimethylsiloxane pyramidal material, which is expected to have a large-scale application in the future civil biomedical field. A layer of silica and silicon nitride are grown on the silicon wafer as a corrosion mask by thermal oxygen and low pressure chemical vapor deposition process, sequentially. After lithography process,...
Inverse reinforcement learning (inverse RL), an inverse process of reinforcement learning (RL), is mainly used to solve problems in extracting a reward function from observed (nearly) optimal behavior of an expert acting in an environment. The extract of a reward function is one of the biggest obstacles of the deployment of reinforcement learning agents in the real world. In many real-world tasks,...
Link prediction has become increasingly popular in complex networks due to its wide application, including extracting missing information, identifying spurious interactions and so on. The simplest framework of link prediction methods are based on similarity index. Most similarity indices are obtained by using the basic topological feature of network, which ignores the impact of some special local...
In a traditional process of software testing, an user have to buy servers and test tools to set up various test environment artificially, which causes high-cost, long test time and difficult test implements with limited resource. Cloud computing integrates a large number of physical resources into a pool and realizes the virtualization of various resources based on virtualization techniques. Users...
Interruptible load management is an important part of demand side management in the power market. Interruptible load management by the power companies and users will be interrupted to sign the contract. The implementation of the interrupt load management needs to solve the problem of determining the outage load contract model, which can interrupt load pricing, and participate in the market operation...
Early identification of emerging technological opportunities is crucial for companies to formulate technology strategies that can provide a core competitive advantage over competitors in the future. It is required to have an effective approach to support industrial practitioners to identify and analyze technological opportunities, especially for a new emerging technology-enabled market. This research...
With the development of optical remote sensing satellite, ship detection and identification from large-scale remote sensing images has become a priority research topic. Specially, inshore ship detection has received increasing attention in many safe and marine applications. However, most of the popular techniques for inshore ship detection are limited by calculation efficiency and detection accuracy...
The modified resin system of 4, 4'-bismaleimidodiphenylmethane ((BDM)/ortho-diallyl bisphenol A(DBA)(BMI)/reactive groups-terminated polyethersulfone (rPESU) (BMI/P)was prepared by melting pre-polymerization. Typical properties (The gelation time, mechanism, phase structure and thermal stability) of the BMI/P resin were systematically investigated, and their origins were discussed. The results show...
This paper addresses the problem of robust topology design of the multi-UAV formation. We use a digraph to model the topology of the multi-UAV formation, and propose the definition of anti-k-communication-destroying topology, meaning the system can still performs normally even when any arbitrary k communicating links are destroyed. By exploring the property of this kind of topology based on graph...
Many scientific applications rely on evaluation of elementary functions. Nowadays, high-level programming languages provide their own elementary function libraries in software by using lookup table and/or polynomial approximation. However, one downside is slow since lookup tables could keep cache thrashing and polynomial approximations require a number of iterations to converge. Thus, elementary functions...
