教练机的航电综合

军用飞机的航电系统日趋综合化,费用也很可观。由于教练机的主要任务是培训飞行员,而不是实战,所以,针对某型教练机,在综合数据、任务、显示控制的基础上,通过建立GPS、火控雷达、CCRP等仿真模型,在平显火控/多功能显示系统中用软件模拟实现了这些功能,从而简化了航电系统,大大降低了成本。利用这种成功的仿真模式,还可以根据需求建立先进武器如导弹、战场态势、防御等仿真模型,在航电系统中进行模拟,使航电系统能进一步得到超值使用。

In‐Vehicle AR‐HUD System to Provide Driving‐Safety Information

Augmented reality (AR) is currently being applied actively to commercial products, and various types of intelligent AR systems combining both the Global Positioning System and computer‐vision technologies are being developed and commercialized. This paper suggests an in‐vehicle head‐up display (HUD) system that is combined with AR technology. The proposed system recognizes driving‐safety information and offers it to the driver. Unlike existing HUD systems, the system displays information registered to the driver's view and is developed for the robust recognition of obstacles under bad weather conditions. The system is composed of four modules: a ground obstacle detection module, an object decision module, an object recognition module, and a display module. The recognition ratio of the driving‐safety information obtained by the proposed AR‐HUD system is about 73%, and the system has a recognition speed of about 15 fps for both vehicles and pedestrians.

Using Pre-construction Validation to Regulate Urban Skylines

This article describes best practices from contemporary scientific protocols that can be used to perform pre-construction validation of urban design guidelines. Because of the prominence of skylines in the urban landscape, their regulation represents a prime candidate for applying design guidelines. We tested guidelines for three prospective skyline factors: overall skyline shape (convex, concave, or flat), number of turns in the roofline of individual buildings (4, 8, or 12), and level of variance in four attributes of individual buildings: height, width, depth, and setback (low, medium, or high). Level of variance in building attributes had the strongest effect on judged pleasantness. The respondents preferred rugged skylines over simple ones, whatever their overall shape. These findings suggest that regulations for skyline appearance should focus on variances in the four building attributes.
