Making use of concrete materials in cut-off walls, because of their low permeability and standing high Hydraulic Gradient caused by underground drainage, has attracted great amount of attention. Using ordinary concrete with high elasticity modulus, compared to other materials may accompany with problems including brittleness of cutoffs due to dynamic stresses. To solve this problem, adding a ce...

Designing an injection molded plastic part requires optimizing the part with respect to various stakeholders’ needs throughout its life cycle. The conditions in which a product is operating in service are often inadequately understood or specified, resulting in wrong material selection, which in turn leads to failure when the product is used. Many aspects interrelate with the initial part desig...

Real-time pose estimation systems are fundamentally difficult to evaluate. Pose estimation performance is a function of the object geometry, environmental conditions, line of sight, sensor characteristics, algorithm characteristics, and computational platform. This paper presents lessons learned from Neptec’s two operational space systems for real-time dynamic pose estimation: the Space Vision ...

This report gives an account on our work in adaptive visualization over the Internet ressearch. In this report we present our prototypes of adaptive visualization systems and an agent-based visualization model for network applications. We propose an intelligent agent system for adaptively dispatching of visualization processes between a cluster of computers based on the changing network transmi...

with the development of internet of things (iot) technologies in recent years, the development of knowledge management systems based on them, as well as the role of these systems in different organizational areas such as staff performance management should be considered. the objective of this study is to design an application based on the iot, and analysis of its role in staff performance impro...

With the rapid growth of networking and high-computing power, the demand of larger and more complex software systems has increased dramatically. To deal with the complexity in designing large-scale complex software systems, the concept of component-based software design has gained popularity recently. However, in pursuing a component-based approach there are obstacles to be overcome. One of the...

We present the design, fabrication, and performance analysis for a class of two-dimensional acoustic cloaking coatings in air. Our approach takes advantage of transformation acoustics and linear coordinate transformations that result in shells which are homogeneous, broadband, and compact. The required material parameters are highly anisotropic; however, we show that they are easily achievable ...
