This paper proposes a graph-based algorithm for constructing 3D Korean traditional houses automatically using a computer graphics technique. In particular, we target designing the most popular traditional house type, a giwa house, whose roof is covered with a set of Korean traditional roof tiles called giwa. In our approach, we divided the whole design processes into two different parts. At a high level, we propose a special data structure called ‘modeling graphs’. A modeling graph consists of a set of nodes and edges. A node represents a particular component of the house and an edge represents the connection between two components with all associated parameters, including an offset vector between components. Users can easily add/ delete nodes and make them connect by an edge through a few mouse clicks. Once a modeling graph is built, then it is interpreted and rendered on a component-by-component basis by traversing nodes in a procedural way. At a low level, we came up with all the required parameters for constructing the components. Among all the components, the most beautiful but complicated part is the gently curved roof structures. In order to represent the sophisticated roof style, we introduce a spline curve-based modeling technique that is able to create curvy silhouettes of three different roof styles. In this process, rather than just applying a simple texture image onto the roof, which is widely used in commercial software, we actually laid out 3D giwa tiles on the roof seamlessly, which generated more realistic looks. Through many experiments, we verified that the proposed algorithm can model and render the giwa house at a real time rate.

This paper presents an innovative electronically controlled suspension system installed on a real car and used as a test bench. The proposed setup relies on a sensor network that acquires a large real-time dataset collecting the car vibrations and the car trim and, through a new controller based on a recently proposed theory developed by the authors, makes use of adjustable semi-active magneto-rheological dampers. A BMW series 1 is equipped with such an integrated sensors-controller-actuators device and an extensive test campaign, in real driving conditions, is carried out to evaluate its performance. Thanks to its strategy, the new plant enhances, at once, both comfort and drivability of the car, as field experiments show. A benchmark analysis is performed, comparing the performance of the new control system with the ones of traditional semi-active suspensions, such as skyhook devices: the comparison shows very good results for the proposed solution.

In order to testify the driving characteristics of 3m homemade steel-belt friction drive test bench, a data detection system under AT89C52 is developed.The system uses two photoelectric encoders as the speed testing unit and one weighing sensor as the strength testing unit.therefore.It is critical to both of them to be used on real time to detect properties,such as rotation speeds, direction, pre-tightening force and dynamic load and so on. It is tested that this system is stable which can record the date of pre-tightening force accurately with the error in the range of 1% and keep transmission accuracy with the error in the range of 0.5%.

According to such properties of DME as high saturated vapor pressure, low viscosity and easy formation of mixture with air, a CPC (Controllable Premix Combustion) low-pressure common rail electrical control fuel injection test bench of DME engine is developed through this research. In addition, an overall design of the test system, hardware and software development of electrical control unit (ECU) and a test on the test bench are undertaken. The software of ECU is programmed by using real time modular programming. It has the advantages of flexible programming, convenient transplantation and wide extending possibility. Test results show that the injector switch timely, spray powerfully and pulverize perfectly. The software accomplishes many tasks such as signal acquisition as well as real-time control requirement of engine operation. Test result also shows the feasibility and good comprehensive performance of low-pressure common rail electronic system for DME fuel.
