Sensors deployment has played an important role in many engineering applications, and the key goal is aimed at achieving an optimal surveillance region with a set of sensors. In this paper, a probabilistic strategy was chosen as the sensing model and a Gaussian probability distribution was employed, furthermore an accumulative probability for all the utilized sensors was presented and an optimal deployment on meshed planar grid was proposed. It was proved that the deployment problem was NP-complete, and an approach for approximating this solution should be resorted to intelligent methods. Particle swarm optimization (PSO) was a widely used artificial intelligent tool, and hereby an improved discrete PSO (DPSO) was proposed for solving the deployment problem, and which was based on integer coding, and the initialization, positions and velocities updating were distinct with the traditional PSO. In final, the deployment was investigated respectively by using uniform sensors (binary coding problem) and combinational sensors (multivariate integer coding problem), which were indicated to the core structure of proposed DPSO. © 2017, Springer-Verlag Berlin Heidelberg.

From a perspective of agricultural machinery and agronomy combination, a method was proposed to analyze corn production mechanization system. Based on the analysis of background and conditions, an analysis framework of corn production mechanization system was put forward, which was focusing on technology integration, organizational integration and management integration. For technology integration, the available agricultural and agronomic technologies those can be combined in the process of production mechanization were analyzed. For organizational integration, the existing categories of service organizations of corn planting and agricultural machinery were summarized to analyze the integration idea and method of the combination of agricultural and agronomic technologies. For management integration, suggestions on resource management, task adjustment and process management were proposed to promote the corn production mechanization.

In order to find the method of auto detecting body temperature in pig's cultivation, the homemade thermal infrared imager was used to acquire the infrared thermograms of pigs. The imager was loaded on the arm of the auto-inspection trolley with the camera lens toward pigs, so it can clearly collect the images of pig ear roots. When the thermograms were collected, they were firstly transformed by HSV colorspace into the S-layer images. Furthermore, the morphological closing operation was used for binary image denoising. Finally, adapted Otsu was applied to ear roots detection of piglets, finishing pigs and pregnant pigs separately. The objective function was selected, because it was simple to find a grayscale to maximize η with the minimum computation at the same time. The results showed that the method can be perfectly used to analyze images with complete ear roots for piglets, finishing pigs and pregnant pigs. When the method was applied to those images with incomplete ear roots, the detection rates were 23% for piglets, 25% for finishing pigs and 33% for pregnant pigs.The method cannot be used to analyze images without any ear roots of pigs. The method was applied to the auto-inspection system which can help to find the high temperature pigs in the cultivation. When the abnormal pigs were found, the auto inspection trolley would alert, and then stopped inspecting and began to spray. © 2016, Chinese Society of Agricultural Machinery. All right reserved.

During the last ten years, the international construction market has kept growing. However, not all the international contractors have good performance according to the study of the rankings of international contractors in ENR TOP 225. The core competence analysis model was established according to the theory and research of the competitiveness in international contracting industry. Two methods to determine the core competences of leading international engineering constructor were confirmed. Firstly, the core competences could be found by studying the market performance to research companies' products, services and core business units. Secondly, the general competences and core competences could be determined according to the enterprises' resources and capabilities to determine. © (2014) Trans Tech Publications, Switzerland.

The higher order crack tip fields for anti-plane crack in Functionally Graded Piezoelectric Materials (FGPMs) under mechanical and electrical loadings are investigated. Different from previous analyses, all material properties of the functionally graded piezoelectric materials are assumed to be power function of x parallel to the crack. The boundary conditions on crack surfaces are assumed to be the stress free and electrically impermeable. Similar to the Williams’ solution of homogeneous elastic materials, the higher order crack tip fields of FGPMs are obtained by the eigen-expansion method. This study possesses fundamental significance as Williams’ solution to homogeneous materials. © 2015, Public Library of Science. All Rights Reserved.

The higher order crack tip fields for an anti-plane crack in functionally graded piezoelectric materials (FGPMs) under mechanical and electrical loadings are studied. Different from previous analyses, all material properties of FGPMs are assumed to be linear functions of x parallel to the crack. The boundary conditions on crack surfaces are assumed to be the stress free and electrically impermeable. By using the eigen-expansion method, the problem is reduced to solving the system of ordinary differential equations. The higher order stress and electric displacement crack tip fields for FGPMs are obtained by solving the ordinary differential equations. © (2014) Trans Tech Publications, Switzerland.

The differences of corn planting-harvesting process and harvesting equipment between China and developed countries, corn harvester developing process and major model were introduced. The general technology and equipment of snapping, husking and straw treatment of corn harvesting machine, and the research and exploration of corn harvesting technology regardless of row in China were expatiated. The major factor for restricting development of corn harvest mechanization in China, the development trend of foreign corn harvester, and planting and harvesting characteristics of Chinese corn producing areas were analyzed. Finally, it pointed out that the corn harvester should be designed with combination of agricultural machinery and technology to suit local condition in China.

An ellipsoid particle model was established according to the physical properties of rice grain. The discrete element method was used to simulate the impact process of a grain with a detection sensor. The results indicated that the peak normal contact force Fn max was increased with the increasing of curvature radius during the central impact process. Rotation of grain was driven during the eccentric impact process which reduced the value of Fn max. The differences of Fn max was enlarged with the increasing of grain radius ratio γ, and the minimal value of peak force ratio η was lower than 45% with γ of 3. The asymmetric variation behavior of η was shown during the oblique impact process and the variation range of η was increased. The minimal value of peak force ratio η was about 30% with γ of 3. The rise time of impact force tr was in the range of 14-26 μs. Then, a detection sensor using piezo-electric polyvinylidene fluoride (PVDF) film as sensitive material was presented and the rice grains impact tests were carried out. The results showed that the peak output voltage was fluctuated in 2-4 V, and the rise time of impact force tr was 15-35 μs.
