Intelligent damage determination refers to the identification of the damage and parts of the vehicle in the picture and video through the image recognition algorithm, and then automatically output the damage of the vehicle. How to accurately judge the size of the damage on the vehicle components is an important step to get the damage of the vehicle. This problem is actually a solution to the intersection of two connected graphs. However, the existing algorithms can only solve some simple and special graphics. In practical applications, the shapes of damage and parts are changeable, and these algorithms can no longer meet the actual needs. This paper presents a universal algorithm for solving the intersection of connected graphs by pixelating the graph and according to the change law of the relative position relationship between the points on the plane and the graph. The algorithm has a wide range of applications and simple input requirements for graphics. The application results of simulation tests and actual scenes show that this algorithm can accurately calculate the intersection of concave polygons, holed polygons and other connected graphics, which has high practical application value.

Various wake oscillator models considering different damping terms are employed for predicting vortex-induced vibration of one degree-of-freedom rigid elastically mounted cylinder in the present work. Three distinct damping terms are considered, i.e. Van der Pol Type, Rayleigh Type and Van der Pol-Rayleigh Type. The dynamic behaviours of wake oscillator models with different damping terms are compared to provide better insights into the mechanism for flows to interact with vibrations of the elastically mounted cylinder. The results shows that the damping effect increases when different damping terms, in the order above, employed in the wake oscillator.

The unreasonable building layout will worsen the wind environment at the pedestrian height around the building. The main objective of this paper is that using ANSYS Fluent software to study the impact of space corridors on pedestrian-level wind environment around buildings and give a reasonable space corridor layout position. In this paper, the calculation model was set up according to the detailed rules of green building evaluation standard to ensure the validity of CFD simulation. Based on the calculation results, the variation laws of different space corridor arrangements on the average wind speed amplification coefficient at pedestrian height in 3 evaluation areas were discussed. It is concluded that the layout of the space corridor in the middle of the buildings which is case-3 is beneficial to the pedestrian wind environment in the street valley of the buildings.

Intravenous infusion is a method frequently used in medical treatment. Locating veins is the prerequisite for intravenous infusion. At present, vein localization in many medical scenarios is still performed manually. However, when encountering infectious diseases, the difficulty of manually locating vein will increase sharply due to the wearing of corresponding protective measures. Inspired by the successful application of deep learning in the field of semantic segmentation, a lightweight neural network is proposed to realize vein visualization from color skin images. The feature loss is included in the training loss to reduce the noise of the visualization result and enhance the smoothness of the image. The network is deployed to a smartphone, which greatly improves the convenience of vein visualization. Experiments were conducted to evaluate the proposed method and its mobile terminal performance. The experimental results show that the proposed method can clearly locate veins in skin areas, and thus can be used to assist medical treatment.

Autonomous Vehicles [AVs] will emerge as a powerful catalyst, thus forming a potentially disruptive technology opening doors to technological, socio-cultural and legal challenges. Present-day research is mainly focused on technological orientation, lacking the predominant social and behavioural linkages. NZ being a testbed of innovative technologies, is facing significant challenges in growing population and traffic congestions. Auckland ranks 47th globally in terms of traffic congestion costing $$1.3$b a year to the economy. Therefore, harnessing AV technology will be a significant step to remain competitive. The people’s readiness for acceptance influences AVs successful implementation. In this background, it is quintessential to ascertain and evaluate critical factors affecting the successful deployment of AVs in NZ. This exploratory research study is a part of a larger project of realizing a trust dynamics and governance framework for humanizing driverless technology. It is being carried out in collaboration with BMW NZ Group using Autonomous Level 2 Vehicle in Auckland on high, medium and low-density roads with level 3 functions mostly. Drawing on systematic qualitative evidence, this study attempted to find out key determinants/variables affecting user acceptance, including anthropomorphism, training, feedback, safety, security, privacy, customization and adaptive automation for AVs deployment in NZ and their role in garnering users’ trust besides suggesting an HMI Autonomous Driving Events Relationship Framework for AVs.
