This paper describes multi-layer traffic engineering and signaling technologies in photonic-GMPLS-router networks. Multi-layer traffic engineering, which yields the dynamic cooperation of IP and photonic layers for providing IP services cost-effectively, is described. To realize multi-layer traffic engineering, we propose an OSPF extension that advertises both the number of total wavelengths an...

in this study, he’s variational approach (va) is used to solve the non-naturalvibrations and oscillations. the method works very well for the whole range of initial amplitudesand does not demand small perturbation. it is also sufficiently accurate to both linear and nonlinearphysics and engineering problems. we consider some examples to illustrate the effectiveness andconvenience of the method....

Berry, Levinsohn and Pakes (1995), or BLP, introduce a widely-used estimator that handles market-level demand shocks and price endogeneity in structural discrete choice demand models. This estimator is necessary to work with demand data from differentiated products industries. The estimator is computationally intensive and difficult to program, largely because a system of market share equations...

The Damped Trend (DT) forecasting method has been recognized for its superior accuracy. Li et al., (2014) show when DT forecasts are used within the order-up-to (OUT) policy, the bullwhip effect is avoided by using unconventional DT parameter settings. We extend this study in three directions. First, by investigating the relationship between the stability and invertibility, we show that stable ...

This paper describes the system we submitted to the SemEval-2014 shared task on sentiment analysis in Twitter. Our system is a hybrid combination of two system developed for a course project at CMUQatar. We use an SVM classifier and couple a set of features from one system with feature and parameter optimization framework from the second system. Most of the tuning and feature selection efforts ...

Information and communication technologies (ICT) have altered the balance of cost between activities within a firm and activities between firms. Easier co-operation allows companies to focus on their core strengths, while forming relations with other firms to supply the other needed skills to bring a product to market. Design, in one firm or in a consortium, is iterative and does require change...

One of the main problems in control engineering practice results from unavoidable errors in specifying parameters existing in the object model and the necessity to deal with the unwanted phenomena arising as a result. In this article, a Bayes methodology considering both asymmetrical and conditional aspects is applied for this purpose, with the application of kernel estimators methodology. Use ...

The Choghakhor International Wetland plays an important role in preserving and protection of part of the plant and animal species in the Iranian plateau. Since the water of this wetland is utilized for different human purposes, complete periodic chemical and physical quality assessment of its water seems necessary. Water quality index (WQI) was calculated using the following eleven parameters: ...
