Average Current Estimation Technique for Reliability Analysis of Multiple Semiconductor Interconnects
Average current analysis checking the impact of
current flow is very important to guarantee the reliability of
semiconductor systems. As semiconductor process technologies
improve, the coupling capacitance often become bigger than self
capacitances. In this paper, we propose an analytic technique for
analyzing average current on interconnects in multi-conductor
structures. The proposed technique has shown to yield the acceptable
errors compared to HSPICE results while providing computational
current moment, interconnect modeling, reliability
analysis, worst-case switching
Security Engine Management of Router based on Security Policy
Security management has changed from the
management of security equipments and useful interface to manager.
It analyzes the whole security conditions of network and preserves the
network services from attacks. Secure router technology has security
functions, such as intrusion detection, IPsec(IP Security) and access
control, are applied to legacy router for secure networking. It controls
an unauthorized router access and detects an illegal network intrusion.
This paper relates to a security engine management of router based on
a security policy, which is the definition of security function against a
network intrusion. This paper explains the security policy and designs
the structure of security engine management framework.

Implementing High Performance VPN Router using Cavium-s CN2560 Security Processor
IPsec protocol is a set of security extensions
developed by the IETF and it provides privacy and authentication
services at the IP layer by using modern cryptography. In this paper,
we describe both of H/W and S/W architectures of our router system,
SRS-10. The system is designed to support high performance routing
and IPsec VPN. Especially, we used Cavium-s CN2560 processor to
implement IPsec processing in inline-mode.

Seismic Fragility for Sliding Failure of Weir Structure Considering the Process of Concrete Aging
This study investigated the change of weir structure performances when durability of concrete, which is the main material of weir structure, decreased due to their aging by mean of seismic fragility analysis. In the analysis, it was assumed that the elastic modulus of concrete was reduced by 10% in order to account for their aged deterioration. Additionally, the analysis of seismic fragility was based on Monte Carlo Simulation method combined with a 2D nonlinear finite element in ABAQUS platform with the consideration of deterioration of concrete. Finally, the comparison of seismic fragility of model pre- and post-deterioration was made to study the performance of weir. Results show that the probability of failure in moderate damage for deteriorated model was found to be larger than pre-deterioration model when peak ground acceleration (PGA) passed 0.4 g.
