Tomato fruit are rich in γ-aminobutyric acid (GABA), which lowers blood pressure and improves sleep. An increase GABA content is important for enhancing the nutritional quality of tomato fruit. To investigate effects 5-aminolevulinic (ALA) on synthesis greenhouse tomatoes, cultivar (Solanum lycopersicum cv. '184') was used as an experimental material. During fruit-setting period, root drenching with 0, 10, 50 mg·L-1 ALA, foliar spraying 50, 100 surface 100, 200 ALA were applied. The study...

Conventional visual and manual road crack detection method is no fit to the development of highway: it time-consuming, non-precise, dangerous, costly. Automatic pavement survey required. This paper treats a problem arising in design intelligent vehicles also describes an automatic based on image processing. It enhances by comparing two fast correct first, then processes segment threshold extracts linear feature. means that diseases processed Ostu algorithm division (by contrasting whole...

To deal with the problem of tracking person a mobile robot in dynamic scene occlusion, system is presented this paper. We focus on individual system, which applied our two-wheel single PTZ (pan-tilt-zoom) camera. The works reliably environment partial/complete occlusion. For sake complete we use several filters and spatial relation restriction to represent target model. These are all based appearance target, each filter models part human body more rigid than entire body. construct...

High-efficiency control of the motion oil film plays a critical role in optimizing electrofluidic display (EFD) technology. In this paper we focus on studying effect different pixel shapes kinetics electrofluidic. Four kinds pixels including square pixel, rectangle trapezoid and triangle were designed discussed. The electro-optic characteristics switching dynamics four arrays studied respectively. results indicate that reduction inscribed circle grid leads to an increase threshold voltage....

The mechanism the process on Cu-Mn surface studied a liner sweep voltammetry experiment, and optimized applied voltage for system recommended. properties monolithic NPC, including morphology, chemical composition, area wettability were systematically characterized. specific around 11.86 m2/g as-dealloyed NPC measured...

On the price of complexity, new video compression standard H.264 is more effective than MPEG-4 in compression. Aimed at motion estimation problem search rate, a directional pattern and an improved cross diamond algorithm which adopts many technologies including prediction initial point, suitable choosing auxiliary points are proposed this paper. Simulation results demonstrate that can effectively enhance rate under similar PSNR.

Deep learning-based methods for building extraction from remote sensing images have been widely applied in fields such as land management and urban planning. However, extracting buildings commonly faces challenges due to specific shooting angles. First, there exists a foreground–background imbalance issue, the model excessively learns features unrelated buildings, resulting performance degradation propagative interference. Second, complex boundary information, while conventional network...

With regard to ground-based astronomy observations, due the interference of atmospheric turbulence, noise and other factors, observed images are degraded, which makes it difficult obtain high-resolution astronomical images. In such case, image restoration is essential. Of all deconvolution algorithms, one based on scaled gradient projection (SGP) highly effective while equipping a high precision fast convergence. But SGP algorithm requires an accurate point spread function (PSF) estimation...

Aiming at overcoming some inherent drawbacks and bottlenecks encountered by the conventional Knowledge, Recommendation, Search, Social Systems, in this article we introduce Knowledge Network System (KNS), a novel type of knowledge graph which is constructed new proposed algorithm, Evolutionary Collective Intelligence (ECI) algorithm. The ECI, an agent-machine interactive constructs KNS iteratively recommending interesting/matched samples/files to agents, meanwhile taking advantages...

Abstract Aiming at the problem of low flexibility and poor scalability Non-Dispersive InfraRed method CO 2 concentration detection equipment, a platform based on Zynq series SoC is designed.

Because of the nonlinear motion robot-fish and uncertain water waves, it is difficult to track dynamic target accurately quickly for robot-fish. To solve this problem, paper proposed tracking strategy underwater based on Unscented Kalman filter (UKF). UKF a filtering basis unscented transformation, which consists prediction update recursively, thus estimate state system. avoid particle degeneracy, selects sigma points adopting scale symmetric sampling strategy. We apply method competition in...

In this paper, a comprehensive evaluation indicator system of urban infrastructure was constructed, and vulnerability assessment model based on AHP method developed. Taking Beijing as an example, empirical research the date in 2008 conducted.
