This article presents the method for training a deep artificial neural network (DANN) for regression analysis; this method is based on the generalized delta rule. To illustrate the rule, a DANN with two hidden layers is used. The model’s construction is described in the form of mathematical equations. Subsequently, a DANN program is written in Visual C# .NET. This program is tested with the task of estimating the shear strength of soil samples.

The paper proposed an ensemble classifier (EC) that is combined by parallel single classifiers. The single classifiers can compensate for the others by combining in parallel. Then, the EC can improve classification accuracy. The paper proposed the use of Multi-layer Perceptron Networks (MLPN) to build EC. The study is tested on IEEE 39-bus power system network.

The influence of various operational parameters including initial dye concentration, catalyst concentration, pH value, inlet gas concentration, and type of irradiation source was investigated on the efficiency of the photocatalytic ozonation removal of DR54. Various inorganic and organic reactive oxygen species (ROS) scavengers were applied to investigate the mechanism of photocatalytic ozonation. In addition, a three-layer perceptron neural network was developed for modeling the relationship between the operational parameters and decolorization efficiency of the dye.

Chapter 2 - Network hardware. The layered model that dominated data communication and networking literature before 1990 was the Open Systems Interconnection (OSI) model. Everyone believed that the OSI model would become the ultimate standard for data communications - but this did not happen. The TCP/IP protocol suite became the dominant commercial architecture because it was used and tested extensively in the Internet; the OSI model was never fully implemented. In this chapter, we first briefly discuss the OSI model and then we concentrate on TCP/IP as a protocol suite.

Enhancer–promoter interactions (EPIs) play key roles in transcriptional regulation and disease progression. Although several computational methods have been developed to predict such interactions, their performances are not satisfactory when training and testing data from different cell lines.

Fused deposition modelling (FDM) is gaining distinct advantage in manufacturing industries because of its ability to manufacture parts with complex shapes without any tooling requirement and human interface. The properties of FDM built parts exhibit high dependence on process parameters and can be improved by setting parameters at suitable levels. Anisotropic and brittle nature of build part makes it important to study the effect of process parameters to the resistance to compressive loading for enhancing service life of functional parts.

In this paper, authors present the overview model of convolutional neural network including major function in each layer and transformations in this network. Based on that theory, authors have designed an application of English handwriting recognition using convolutional neural network as well as having comparative tests between some recognition algorithms.

The system’s architecture is based on an original design that constitutes a vNIC, a physical network interface card (pNIC), and a software. The vNIC creates the virtual host, while the relay system manages the software. Thus, pNIC provides an interface between the physical layer and the software layer. Finally, we conduct empirical testing of the proposed system’s viability using real-life Internet-based research. The results show that our proposed system performs effectively and has good operability.

Managing Small Office WLAN An Ideal Solution from D-Link White Paper May, 2009 Abstract The deployment of wireless local area network (WLAN) in a small office environment is often hindered by the lack of simplicity, stability and affordability. Multiple access points (APs) will require more effort in configuration and management, and the complexity of security settings adds to the burden. With limited resources in a small office, solutions provided for bigger organizations will be too complicated and not economical.

Like most networking software, TCP/IP is modeled in layers. This layered representation leads to the term protocol stack, which refers to the stack of layers in the protocol suite. It can be used for positioning (but not for functionally comparing) the TCP/IP protocol suite against others, such as Systems Network Architecture (SNA) and the Open System Interconnection (OSI) model. Functional comparisons cannot easily be extracted from this, because there are basic differences in the layered models used by the different protocol suites.

As WLANs (Wireless Local Area Networks) become increasingly common, it's becoming vital to be able to test them for proper performance and to optimize their operation. This book, written by a member of the IEEE committee that develops WLAN standards, is the first book addressing that need. It covers test equipment and methods for the RF (wireless) and physical layers of WLAN, protocols, the application layer, and manufacturing testing.

Abstract: The purpose of this white paper is to present discussion and findings that conclude that Cisco MPLS-based VPNs are as secure as their layer 2 counterparts such as Frame- Relay and ATM. This document details a series of tests were carried out on a Cisco router test bed validating that MPLS based VPNs (MPLS-VPN) provide the same security as Frame-Relay or ATM. ATM and Frame-Relay have a reputation in the industry as being secure foundations for enterprise connectivity. Essential items that make ATM and Frame-Relay a secure network were considered and tested on an MPLS-VPN.

The ping command is a good tool for troubleshooting Layers 1 though 3 of the OSI model and diagnosing basic network connectivity. Using ping sends an ICMP packet to the specified device (workstation, server, router or switch) and then waits for a reply. The IP address or host name can be pinged. In order to ping the host name of a router, there must be a static host lookup table in the router or a DNS server for name resolution to IP addresses.

This lab focuses on the Telnet (remote terminal) utility to access routers remotely. Telnet is used to connect from a local router to another remote router in order to simulate being at the console on the remote router. The local router acts as a Telnet client and the remote router acts as a Telnet server. Telnet is a good testing or troubleshooting tool since it is an application layer utility. A successful Telnet demonstrates that the entire TCP/IP protocol stack on both the client and server are functioning properly. Telnet from the workstation as a client into any router with...

This lab is designed to be a build-to-specifications test. There are numerous issues that need to be addressed for this lab to work correctly. The lab is designed to illustrate some of the problems associated with NBMA networks and linkstate routing protocols such as OSPF. Although the lab specifications will require you to solve problems in ways that you will probably never see in a production network, you will find that the same problem can be solved more than one way, sometimes using layer 2 techniques and sometimes using layer 3 techniques.
