Research and Application on Reverse Engineering of Tooth Surfaces of Hypoid Gear Limei Zhanga, Lixin Nieb Henan Polytechnic University, Jiaozuo, Henan Province, 454000, China azlm@hpu.edu.cn, bnielixin@hpu.edu.cn Keywords: Reverse Engineering, Hypoid Gear, Boundary Conditions, Active Design Abstract.
Reverse engineering, which is an approach for constructing a CAD model from a material solid through dimensional measurement and surface modeling, could be used to structure digitized tooth surfaces of hypoid gear.
The reverse engineering of a NURBS tooth surface can be considered as specific number of curve's reverse solution, and the key is the structure of control equations and the selection of boundary conditions in each of reverse processes.
Control points of NURBS tooth surface can be obtained from data points by reverse engineering.

So analyzing the influencing factors of engineering cost control is the key point to finding the solution of these problems.
The unbalanced supply and demand relation of building materials, labour and construction machinery.The price of building materials directly affect the engineering cost in the post-disaster reconstruction period.
Otherwise, the transportation in many disaster areas are in palsy state, which makes it very difficult to transport large mechanism and materials.
Strengthen the construction materials management.
In order to effectively control the composite price of construction materials and avoid the risk owing to the market asymmetric information, it is requisite to build the price inquiry and price bulletin system, ensuring the construction enterprises to select the construction materials suppliers and transporters through comparison and bidding method, and recognize the professionals to inquiry the price of materials and equipments.

The authors present the development of a scientific cloud computing environment (SCCE) for engineering and business simulations that offers high performance computation capability.
The use of advanced engineering simulation technology allows engineers to understand and predict the future performance of complex structures and systems designs which can be optimized to reduce risk, improve performance or enhance survivability.
The code is designed for the realization of large-scale ab initio calculations on parallel computers, and thereby we expect that OpenMX can be a useful and powerful tool for nano-scale material sciences in a wide variety of systems such as bio-materials, carbon nanotubes, magnetic materials, and nanoscale conductors [7].
