Existing approaches to combined performance and availability modelling of multi-layered service systems do not consider the delays associated with the detection of failure (repair) and subsequent reconfiguration. The detection delay influences the runtime overhead while both of them together affects the system downtime. The effect of these two types of delays should therefore be considered for ...

This paper investigates the lateral vibration of single-layered graphene sheets based on a new theory called doublet mechanics with a length scale parameter. After a brief reviewing of doublet mechanics fundamentals, a sixth order partial differential equation that governs the lateral vibration of single-layered graphene sheets is derived. Using doublet mechanics, the relation between natural f...

In this study, we investigate the effects of treatment with layered chondrocyte sheets and synovial cell transplantation. An osteochondral defect was created of 48 Japanese white rabbits. In order to determine the effects of treatment, the following 6 groups were produced: (A) synovial cells (1.8 × 10(6) cells), (B)layered chondrocyte sheets (1.7 × 10(6) cells), (C) synovial cells (3.0 × 10(5) ...

Layered learning is a hierarchical machine learning paradigm that enables learning of complex behaviors by incrementally learning a series of sub-behaviors. A key feature of layered learning is that higher layers directly depend on the learned lower layers. In its original formulation, lower layers were frozen prior to learning higher layers. This paper considers an extension to the paradigm th...

In this paper, we present an optimal solution to the problem of error control in layered and replicated media systems satisfying real-time delay constraints. In doing so, we rely on an apriori estimate of loss along with a hybrid proactive FECARQ scheme to statistically guarantee the quality of service for receivers. Our optimal Layered Media Multicast Control (LMMC) solution to a formulation o...

This paper surveys the current state of the object-oriented paradigm as it applies to the handling of geo-referenced information. The model of any computerized system is multi-layered, with a high-level system-independent conceptual model of the application domain supported by increasingly system-oriented models beneath. The author argues that object-oriented approaches can be taken at each of ...

We study nonlinear waves in a two-layered imperfectly bonded structure using a nonlinear lattice model. The key element of the model is an anharmonic chain of oscillating dipoles, which can be viewed as a basic lattice analog of a one-dimensional macroscopic waveguide. Long nonlinear longitudinal waves in a layered lattice with a soft middle (or bonding) layer are governed by a system of couple...

Layered space-time codes have been designed to exploit the capacity advantage of multiple antenna systems in Rayleigh fading environments. In this paper, we present a new efficient detection algorithm based on a sorted QR decomposition. It only needs a fraction of computational effort compared to the standard detection algorithm requiring multiple calculations of the pseudo inverse of the chann...

This paper presents an integrated method to help design and implement a Web-based Decision Support Systems (DSS) in a distributed environment. First, a layered software architecture is presented to assist in the design of a Web-based DSS. The layered software architecture can provide a formal and hierarchical view of the Web-based DSS at the design stage. Next, a component-based framework is pr...
