The morphological characteristics of the canal section are significantly different from those of natural rivers. In this paper, the cross-sectional morphological characteristics of the canal are studied based on the measured section data of the inland waterway in Jiangsu Province, China. A regression analysis of the cross-section of the canal revealed that the shape of the stable section conformed to the parabolic function, and parameter A can be used to characterize the width of the section. The statistical analysis of the width-to-depth ratio of cross sections revealed that the width-to-depth ratio distribution range in those canals has obvious geographical differences. It is suggested that the quadratic function coefficient A and the width-to-depth ratio can be used as the two cross-section parameters to describe the cross-sectional shape of the canal waterway

The leaf spring is an important component in the suspension system of the vehicle and the parabolic leaf spring is widely applied in the modern vehicles. Accounting for the symmetricity of the structure and loading condition, the leaf spring is simplified to be a planar structure to analyze. Based on the absolute nodal coordinate formulation (ANCF), the computer aided design (CAD) geometric model is transformed directly to the computer aided analysis (CAA) finite element (FE) model. The linear transformation from Bezier triangle to the ANCF triangular element mesh and the general method to construct the curved structure using the ANCF triangular element are proposed. Thus, the integration of CAD and CAA system is facilitated. Using the ANCF element, the complex and time-consuming transformation from the CAD model to the CAA model with the conventional FE is avoided. As a result, the unnecessary error introduced in the intermediate transformation is avoided. The simplified suspension system including a mono-leaf parabolic leaf spring is built and the transient analysis is conducted. The results are compared against those obtained by the commercial FE software ANSYS.

The sea-sky line is an important geographical indication for the detection and tracking of targets on the sea. When a long-range offing target appears, it must be in the sea-sky line area. According to the features of sailing on the sea and six degree-of-freedom movements, an algorithm for realtime position of sea-sky line is proposed. Firstly, the model of the sea camera is constructed. Then according to the projection transformation, the relativity between geographic coordinate system and image coordinate system is derived by means of geometrical deduction. Finally, the mathematical model of sea-sky line is obtained. Experimental results show that the algorithm is accurate, efficient and robust, which lays the foundation for the next visual research of ships.

This paper is aimed at providing potential strategies of car-sharing promotion in a real market. To get more attraction and profits, car-sharing companies are focusing on the customers' interests and rights. In order to better address the issue, several successful car-sharing organizations and sharing concept are introduced firstly, and next we concentrate on the benefits of this new traffic mode. Thirdly, the characteristics of car-sharing members are discussed, and experimental results indicate that car-sharing is often used by some specific population. Further, existing problems/solutions in parking area and person-to-person car-sharing system are expounded. And parking reservation strategies are proposed to balance the demand and supply of parking space concurrently. Finally, this work takes Uber as an example to explore the legitimacy of car-sharing organizations, which turns out that these organizations do not need more regulations and the life cycle of shared cars is investigated as well.

Using UAV to create map of environment for further UGV path planning could give much benefits, because UAV has better field of view and could process big areas quicker. Different approaches exist to store resulting map (such as elevations maps, octomaps, etc.), but most of them are operating with point clouds at some step. This article shows practical way to directly use point clouds to plan traversable UGV path. It allows to skip discretization of space as usually done and utilize all data available. This work presents algorithms for point cloud based terrain assessment and global path planning with rapidly exploring random trees (RRT). Publicly available datasets of UAV-generated point cloud maps are used for experiments. Article gives quantitative estimation of performance of planning on point cloud map on CPU and practical realization details. Highlights-Proof practicability of UGV traversable global path planning directly on point cloud, generated from UAV; Shows experimental results on publicly available datasets; Gives quantitative estimation of performance of planning on point cloud map on CPU and practical realization details.

The crashes were mapped using two separated and independent Linear Reference Systems (LRSs) to meet different traffic business needs within the Wisconsin Department of Transportation (WisDOT). The State Trunk Network (STN) is the early-developed LRS for the interstate and state roads, while the Wisconsin Information System for Local Roads (WISLR) includes all roads with a detail for the local roads. A link_link table has been developed to easily translate the data from the high-resolution STN to the lower-resolution WISLR network. However, the reverse translation is more challenge due to the ambiguities. This paper presents a utility to realize the opposite translation automatically without influencing other existing business programs. In this utility, rules are set to partially avoid the ambiguities. The results of the quality assurance/quality control indicate that the proposed utility is feasible and accurate.

The problems such as decrease of ship stability and transverse inclination are bound to be generated during the loading and unloading of cargo. In order to solve this problem, this paper takes the “Influence of Loading and Unloading Heavy Cargo on the Ship Stability” as the topic, and makes a deep research. First, it expounds the relevant concepts involved in the transportation of heavy goods in detail. Then, based on the theory of ship statics and comparing with previous research results, this paper summarizes and compares the ship stability calculation methods of loading and unloading, and proposes a general calculation method for ship stability, based on which it deduces the calculation method of ship's initial stability height and transverse inclination angle of the ship's heavy lifting considering the change of boom elevation when loading and unloading the heavy cargo. On the basis of this method, this paper analyzes the basic factors that affect the ship stability and the transverse inclination during the loading and unloading of heavy cargoes, and puts forward the specific method to adjust the transverse inclination. Finally, it verifies the above method taking “M/V Dafu” as a calculation example. Apparently, it can be seen from the calculation results that the calculation precision has reached the actual production requirement, and the change of the ship's initial stability is only related to the elevation angle of the boom. Thus, the transverse inclination of ship caused by loading and unloading of the heavy cargo can be adjusted by the allocation of ballast water.
