We describe an architecture and Medium Access Control (MAC) protocol for WDM networks. Our system is based on a broadcast star architecture and uses an unslotted access protocol and a centralized scheduler to efficiently provide bandwidth-on-demand in WDM networks. To overcome the effects of propagation delays the scheduler measures the delays between the terminals and the hub and takes that de...

level and the procedural memory network related to the action itself. The abstract layer forms the “connector hub” in the action space and consists of single neurons coding for different actions at an abstract level (like reach, grasp, push, tool use etc). The abstract action layer is similar to “canonical neurons” found in the pre-motor cortex that are activated at the sight of objects to whic...

This paper presents investigations into the development of linear quadratic regulator (LQR) robust control of a flexible link manipulator. The dynamic model of the system is developed using a finite element methods (FEM). The problems of a flexible link manipulator are uncertainties and parametric nonlinearities. Previous researches have fathom around control methods for the system, few present...

This paper discusses the application of recurrent neural networks for identification and control of helicopter vibrations. A class of recurrent networks called Memory Neuron Networks are used for plant identification and control. These networks are obtained by adding trainable temporal elements to feed-forward networks. This makes the network output history sensitive and gives them the capabili...

Design of network, through which data, packages or even people can be transported, is an important issue for achieving a desired level of service quality at an acceptable cost. For this purpose, it is possible to design a network comprised of nodes that are connected to each other with dedicated lines. However, this kind of solution will not be cost effective. In order to decrease the total tra...

The stem cell niche provides a supportive microenvironment to maintain adult stem cells in their undifferentiated state. Adhesion between adult stem cells and niche cells or the local basement membrane ensures retention of stem cells in the niche environment. Drosophila male germline stem cells (GSCs) attach to somatic hub cells, a component of their niche, through E-cadherin-mediated adherens ...

In portable specially appointed systems (Manets), there is no altered foundation. A standout amongst the most broadly utilized directing conventions for a specially appointed system is the Ad hoc On Demand Distance Vector steering convention, shortened as AODV. In the customary AODV steering convention, source hub advances RREQ (Route Request) bundle to discover way to the terminus hub. The mod...

Although papillary renal cell carcinoma (PRCC) accounts for 10%-15% of renal cell carcinoma (RCC), no predictive molecular biomarker is currently applicable to guiding disease stage of PRCC patients. The mRNASeq data of PRCC and adjacent normal tissue in The Cancer Genome Atlas was analyzed to identify 1148 differentially expressed genes, on which weighted gene co-expression network analysis wa...

Inclement weather at an airline's hub airport can be devastating to that airline's schedule. The repercussions resonate throughout the airline's network as capacity is reduced, connections are missed, and passengers are delayed on a larger scale than during irregular operations at a spoke airport. The main hypothesis behind the work presented in this thesis is that by shifting a small fraction ...
