We present a simple three-layer assignment algorithm for planar layouts generated by a class of layout algorithms. This class of algorithms includes simple variations of the following algorithms developed by Mehlhorn et al. (1986): (i) The algorithm that generates planar layouts for the two-terminal net CRP with dmax tracks. (ii) The algorithm that generates planar layouts for the twoand three-...

This paper proposes the use of a class of feedforward artificial neural networks with polynomial activation functions (distinct for each hidden unit) for practical modeling of high-order Volterra systems. Discrete-time Volterra models (DVMs) are often used in the study of nonlinear physical and physiological systems using stimulus-response data. However, their practical use has been hindered by...

While the development of Organizational Memory (OM) has become common, the evaluation of these initiatives is yet a challenge. There are several reasons for this. On the one hand, there are various OM realizations possible. On the other hand, there is a lack of evaluation methodologies. We suggest the KnowledgeEco ontology-based methodology as an evaluation tool for OMs in organizations. Drawin...

In this paper we study two important reliability issues in deep submicron VLSI design, namely antenna eeect and crosstalk noise, in the context of three-layer channel routing. Cost functions for both of the failure mechanisms are introduced and based on these cost models, reliability enhancement techniques are presented. For antenna eeect minimization, a layer reassignment algorithm is adopted ...

Increasing popularity of decentralized Peer-to-Peer (P2P) architecture emphasizes on the need to come across an overlay structure that can provide efficient content discovery mechanism, accommodate high churn rate and adapt to failures in the presence of heterogeneity among the peers. Traditional p2p systems incorporate distributed client-server communication, which finds the peer efficiently t...

introduction: the penetration depth of irrigating solutions in dentinal tubules is limited; consequently, bacteria can remain inside dentinal tubules after the cleaning and shaping of the root canal system. therefore, new irrigation systems are required to increase the penetration depth of irrigating solutions in dentinal tubules. methods: a comparative study regarding the penetration depth of ...

irrigation management, soil tillage method and fertilizer management play important roles in increasing crop yield and water and solute movement in the soil profile. the present research was conducted to study the effects of a no-tillage system and nitrogen fertilizer on the mineral nitrogen movement and soil moisture under optimum irrigation conditions. the study was conducted at safiabad agri...

The hybrid ARIMA-SVMs prediction models have been established recently, which take advantage of the unique strength of ARIMA and SVMs models in linear and nonlinear modeling, respectively. Built upon this hybrid ARIMA-SVMs models alike, this study goes further to extend them into the case of multistep-ahead prediction for air passengers traffic with the two most commonly used multistep-ahead pr...

How to help patients find their departments or wards is an issue that needs to be solved by hospitals urgently. This paper presents an iBeacon-based indoor positioning system for hospitals. It firstly analyzes the advantages of iBeacon compared with the common indoor positioning technologies; then designs the indoor positioning system for hospitals based on the three-layer architecture of Inter...
