This paper presents a design method of broadband radar absorber (RA) combining together the features frequency selective surfaces (FSSs), subwavelength hole array, and magnetic absorbing sheets. The is constructed periodic array square conducting patches embedded into substrate perforated with circular arrays backed by metal ground. absorption characteristics are tuned improved means perforating holes embedding FSSs. After optimizing dimensions FSSs, RA thickness 2.4 mm achieves reflection...
Despite the great success of deep learning in many fields such as computer vision, natural language processing, and information retrieval, there are relatively few studies on convergence convolutional neural networks (CNNs), is a lack theoretical necessary conditions for CNNs. The initialization convolution kernel CNNs an important factor whether network can converge. However, existing methods do not analyze influence their performance did application, thus best different models. In this...
This paper introduces DFTs-OFDM to the QAM-based quantum noise stream cipher (QNSC) transmission system. Results show that applying can help QNSC improve signal quality.
The Web has been rapidly deepened by many searchable databases online recently. Those can be accessed through form-based search interfaces that allow users to specify query conditions. For integrating databases, the very first challenge is understand interface. Such a interface considered as an schema with multiple attributes, however, created autonomously and its not defined in HTML which makes extraction of task. In this paper, we propose novel approach automatic logic attributes from...
Abstract Satellite communication is integral to modern systems, yet navigating the intricacies of routing in networks characterized by high loads and dynamic evolution poses a significant challenge. This research dedicated enhancing satellite algorithms, with goal bolstering network efficiency amplifying success rate business transmissions. Our approach introduces an improved simulated annealing algorithm incorporating adaptive temperature control innovative path neighborhood exploration...
Abstract This paper focuses on solving the routing optimization problem under dynamic topology of satellite communication network. With rapid development low-earth-orbit (LEO) network technology, dynamically changing networks has brought about frequent link switching and triggered a large number updates. proposes an improved algorithm named Stable A-Star Routing (SASR) algorithm. The SASR is based A-star aims to reduce path-switching frequency enhance path stability by optimizing selection...
We propose an energy-aware algorithm based on impairment-aware information (EAIA) to improve the energy efficiency in flexible-grid optical networks. Simulation results validate that our proposed EAIA have higher than traditional without impairment information.
The OTN over WDM network is one of the best solutions optical transmission network. As a traditional multi-layer network, traffic grooming algorithms in have been fully studied. However, cross-connects capacity management problem node still under study. In our previous work, an numeric model proposed to analyze node, and results show that LIU placement ratio 60%-70% backbone this paper, we pushed heuristic algorithm called minimum blocking probability optimization (MBPO) for solving problem....
The location technologies, such as GPS and telegraphy, are producing more data of moving objects. Spatio-temporal database is needed to manage these data, so solve the problems in spatio-temporal applications. However, there few prototypes systems yet. This because attention always paid on some specified aspects not whole system. In this paper, we present design implementation a prototype for managing A Trajectory Model proposed where objects' movements 2D plane over time treated...
The particle of the PSO algorithm is lack ofparticle diversity, and this makes itself fall into thelocal extremum, which leads to premature. Basedon a large number experimental analysis, paperindicated that reason lead thePSO algorithm's diversity PSOalgorithm's rapid convergence smallprobability speed divergence.According this, paper comes up with analgorithm extend random factor named RPSOalgorithm from (0, 1) (-1, 1), theparticle velocity has divergence probability thenincreases so...
The starting point detecting function is used in the welding robot. Currently, it only when workpiece has translated. However, practice, not translation, but also rotation. Therefore, algorithm research of important significance to practical application principle analyzed. which detect two surfaces studied systematically. mathematical expressions are proposed based on coordinate translation and errors between taught actual positions groove obtained. A teaching example given. weld plastics...
At present, with the rapid development of satellite communication, people have paid more attention to satellite-ground station routing algorithm. Ant colony optimization (ACO) has good robustness. But it is not easy obtain optimal solution. We propose an Improved Colony Optimization-Tabu Search Satellite-ground Routing (IACO-TSSGR) The simulation results show that, after convergence, better performance than ACO. After algorithm its pathfinding failure rate 0%, while ACO's still 8%. So, can...
Different from general multi-failure, group-failure in cross-layer intelligent optical networks has the characteristic of cluster. Because multi-failure may occur due to single failure, it is more harmful for than failure. The original survivability with regards multiple failures not suitable based research. Group-failure eager be solved networks, and corresponding key theory technology are anxious proposed. This paper mainly focuses on performance networks. Three topics paid attentions to,...
