Recently, human being’s curiosity has been expanded from the land to sky and sea. Besides sending people explore ocean outer space, robots are designed for some tasks dangerous living creatures. Take exploration an example. There many projects or competitions on design of Autonomous Underwater Vehicle (AUV) which attracted interests. Authors this article have learned necessity platform upgrade a previous AUV project, would like share experience one task extension in area fish detection....

Collision risk index is important for assessing vessel collision and one of the key problems in research field avoidance. With accurate obtained through movement parameters encounter situation analysis, pilot can adopt correct avoidance action. In this article, a estimation model based on support vector machine proposed. The proposed method comprises two units, that is, machine–based unit predicting genetic algorithm–based optimizing machine. algorithm are illustrated empirical analysis...

Road traffic safety is essential, therefore in order to predict fatalities effectively and promote the harmonious development of transportation, a prediction model based on support vector machine established this paper. The selection parameters greatly affects accuracy machine. Introducing particle swarm optimization can find optimal improve by parameter optimization. However, standard easy trap into local optimum, so that best solutions cannot be found. Therefore, mutation operation genetic...

Abstract To obtain a speaker’s pronunciation characteristics, method is proposed based on an idea from bionics, which uses spectrogram statistics to achieve characteristic give stable representation of the linear superposition short-time spectrograms. deal with issue slow network training and recognition speed for speaker systems resource-constrained devices, traditional SOM neural network, adaptive clustering self-organizing feature map (AC-SOM) algorithm proposed. This automatically...

An optical single-channel color image encryption scheme based on chaotic fingerprint phase mask and diffractive imaging is proposed. In this proposed scheme, the used to generate random masks served as a secret key directly. Additionally, generated by fingerprint, Lozi map, secure hash algorithm (SHA-256) are only interim variables. With help of placed at different diffraction distances, that encoded into grayscale pattern phase-truncation technique encrypted noise-like pattern. For...

Abstract A crucial aspect of self‐control is the voluntary inhibition impulsive actions. Stimuli can elicit impulses (or preparation) to act not only in presence but also absence perceptual awareness, whether people control action elicited by unconscious stimuli remains unclear. This study used a masked prime version Go/NoGo/Free task and combined mathematical modeling behavioral data investigate impulses. In experiment, when subliminal stimulus triggers impulse, participants need freely...

The effects of non-heat-induced and double-induced(heat-induced Na+-induced) whey protein isolate nanoparticles (WPINs) at concentrations C = 1 %, 2 5 % as well oil fractions (φ 0.1, 0.4, 0.7) on the properties food-grade Pickering emulsions (PEs) were systematically investigated. At a Na+ 300 mM, particle size double-induced WPINs (290 μm) is significantly larger (P < 0.05) than that (210 μm). PEs stabilized by exhibited small compared to those under identical fraction WPIN concentration...

MLPQ/GIS [4,6] is a constraint database [5] system like CCUBE [1] and DEDALE [3] but with special emphases on spatio-temporal data. Features include data entry tools (first four icons in Fig. 1), icon-based queries such as @@@@ Intersection, Union, Area, Buffer, Max Min, which optimize linear objective functions, for Datalog queries. For example, 1 we loaded displayed that represents the midwest United States two contraint relations describing movements of persons. The query icon opened...

Shockwave detection is critical in analyzing shockwave structure and location. High speed video imaging systems are commonly used to obtain image frames during control experiments. Image edge algorithms become natural choices detecting shockwaves. In this paper, a computer software system designed for introduced. Different algorithms, including Roberts, Prewitt, Sobel, Canny, Laplacian of Gaussian, implemented can be chosen by the users easily accurately detect Experimental results show that...

One of the important directions for gas metering is network transmission, such that web management system can directly acquire data usage different customs, and give billing pricing without human interaction. The meter typically no wire connection safety consideration, so wireless communication necessary. An appropriate module plays an role wirelessly transferring meter. Therefore, we tried several kinds transmission modules, as nRF24L01, CC1101 WIFI module, to find out some cost-effective...

Hyperspectral Images are a set of narrow spectrum band images used in the recognition and mapping surface materials such as minerals vegetation. Usually these Image datasets high dimensional which makes its classification process complex task low accuracy by using conventional approaches. dimensionality reduction feature have become necessary steps multi-dimensional hyperspectral image processing. This study investigates an effective algorithm for extracting spatial features stationary...
