Abstract This work is concerned with the finite‐time consensus of leader‐following non‐linear multi‐agent systems by means distributed event‐triggered impulsive control. The protocol first put forward based on strategies, where instants are determined proposed condition. For condition, it not only determines but also effects update time Moreover, compared existing controllers, controller designed in this does contain any sign function, thereby overcoming chattering phenomenon. In addition,...

Social media, such as social network (e.g., Facebook), microblogs (e.g. Twitter) have experienced a spectacular rise in popularity, and attracting hundreds of millions users generating unprecedented amount information. Twitter, for example, has rapidly gained approximately 500 million registered 2012, 340 tweets daily. Although each tweet is limited to only 140 characters, the aggregate may provide realistic representation landscapes certain topic interest. Furthermore, with widespread use...

This paper presents a digital image encryption scheme based on an amnesic super chaotic system. First, the performance of hyperchaotic system with addition memristor is analyzed, such as phase track map, Lyapunov exponential Pongalai cross-section, and other tests. The test results prove that has better hyper-chaotic properties. proposed in this generates initial value through SHA3-256 function to realize 'one one secret.' Chaotic sequences are generated by memristive used encrypt image....

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) have been extensively documented as posing significant health risks to human populations. However, there is a lack of research their impact on endangered species, which significantly affects the effectiveness conservation efforts maintenance these In this study, we examined levels PFAS pollution in adults juveniles vulnerable Saunders’s gull ( Larus saundersi ), along with various food sources using ultra high-performance liquid...

Social media represents an emerging source of big data with rich mobility information embedded. While extensive studies in cartography, geographic science, and visualization have been conducted to extract movement patterns from spatial data, new challenges opportunities arise for deriving at scale massive social data. Conventional methods (e.g. flow mapping) cannot effectively capture features the process addressing concerns such as visual clutter. Furthermore, these are not scalable volume...

Abstract To enhance the precision of trajectory tracking control in industrial robots, a nonlinear end-to-end sliding mode algorithm for robots based on dung beetle is proposed. By employing terminal to resolve issue inadequate performance and integrating optimizer (DBO) parameter adjustment, significant enhancements are achieved accuracy.

Abstract A layer multiplexing-based encrypted image scheme for DNA color images is proposed. Firstly, a memristor added to the Sprott-B chaotic system make it fourth-order memristorised hyper-chaotic system. The hyperchaotic has better pseudo-randomness. encryption proposed generates initial value of by SHA3-256 function achieve “One image, one secret”. sequence generated memory encrypting image. process includes zero complements, chunking, encryption, multiplexing, decryption, and improved...

The vibration of the main landing gear is principally generated during aircraft process, which not only affects safety aircraft, but also causes wear and tear on components, thereby affecting reliability system. induced by various factors, related to natural frequency range structure in root. Hence modal analysis first importance investigate suppression gear. In this paper, six-wheel bogie under research establishing finite element model through use Hypermesh, obtaining its six frequencies...

With the development of nuclear technology, safety analysis methodologies were advancing from traditional conservative to more realistic approaches. For CPR1000-type NPP, Conventional Method (CM) which employed MEDUSE, PERSEE and REFLET codes in order was still use evaluate LB LOCA mass energy release (MER). This complex operation yielded excess result as well inconvenience. Meanwhile, a deterministic method (MDR) had been applied using Realistic code CATHARE GB for MER EPR design. In this...

Taking west quay No.15 bridge reinforcement in Beijing as an example, the application of steel-concrete composite structure T girder engineering is analyzed this paper, which focuses on performance comparison before and after such bearing capacity (bending, shear), dynamic characteristics (natural frequencies natural period). Data analysis results show that Bridge bending shear carrying greatly increased so by steel mixed method, meets requirements specification provides important basis for...

In order to enhance the efficiency and obtain more safety margin in new type nuclear power plant design, it is of great necessity significance study potential probability vessel structure design improvement which based on CPR1000 NP. this paper, LB LOCA chosen as typical accident with CATHARE GB code DRM applied. Sensitivity in-vessel structure, length fuel rods water inventory are performed. The result shows that by reducing between bottom core inlet, extending rod increasing primary...

To manage climate challenge and optimize energy supply structure, China has decided to develop more nuclear power in a safe high-efficiency manner. On sustainable development perspective, it is necessary closed fuel cycle (CFC) system also take great efforts improve natural uranium (NU) utilization ratio of thermal reactor. CANDU certainty play an important role this strategy. This paper presents CNNC Third Qinshan Nuclear Power Company Limited (TQNPC) being the engineering technologies...

Candu Energy, based on its highly successful CANDU 6 (C6) reactors proven four continents, is preparing to launch C6 referenced Generation III products: Enhanced (EC6), the natural uranium optimized, and Advanced Fuel Reactor (AFCR), alternative fuel reactors. The AFCR design EC6 with appropriate changes reactor core cater for cycles post Fukushima improvement.. paper reviews common basis of these then discusses unique advantages market specific features each product. implementation plan...
