TL;DR: This paper explores the use of a model neural network for motor learning that can represent smooth nonlinear functions, yet has simple training rules with a single global optimum.
Abstract: This paper explores the use of a model neural network for motor learning. Steinbuch and Taylor presented neural network designs to do nearest neighbor lookup in the early 1960s. In this paper their nearest neighbor network is augmented with a local model network, which fits a local model to a set of nearest neighbors. The network design is equivalent to local regression. This network architecture can represent smooth nonlinear functions, yet has simple training rules with a single global optimum. The network has been used for motor learning of a simulated arm and a simulated running machine.

TL;DR: In this article, the authors present initial network architectures and capacity-efficient design for an IP/Optical network with highly dynamic IP and wavelength services, restoration against up to 3 failures, and aggregate traffic levels that represent a 10-fold increase over today's network traffic.

TL;DR: In this article, a method for redirecting a traffic flow in a communication network, in which a first or default service path has been configured for the traffic flow to go through is disclosed.
Abstract: A method for redirecting a traffic flow in a communication network, in which a first or default service path has been configured for the traffic flow to go through is disclosed. The method comprises: receiving a notification message from a network node, the notification message including a traffic characteristic information of a packet of the traffic flow; creating a set of rules based on the received traffic characteristic information; and sending the set of rules to a plurality of switches in the communication network, the set of rules configuring a second or alternative service path to be used by subsequent packets of this traffic flow. Also, a network node for carrying out this method is provided.

TL;DR: Two distribution network design problems, i.e., static and expansion planning, are solved using PSO and a novel encoding/decoding technique is devised to represent the network as a particle in PSO for mono- and multi-objective optimization of distribution networks.
Abstract: This paper presents a comprehensive study on mono- and multi-objective approaches for electrical distribution network design using particle swarm optimization (PSO) Specifically, two distribution network design problems, ie, static and expansion planning, are solved using PSO The network planning involves optimization of both network topology and branch conductor sizes Both the planning problems are used to illustrate mono- and multi-objective optimization of distribution networks Firstly, three PSO variants, ie, PSO with inertia weight (PSO-IW), PSO with constriction factor (PSO-CF), and comprehensive learning PSO, are evaluated on a mono-objective (minimization of total cost of installation and energy loss) static planning problem A novel encoding/decoding technique is devised to represent the network as a particle in PSO Also, a heuristics based branch conductor size selection algorithm has been developed and used Statistical tests performed to compare the performances of the three PSO variants reveal that the PSO-CF exhibits relatively better performance Subsequently, the PSO-CF is applied for mono-objective expansion planning and multi-objective static and expansion planning problems In the multi-objective planning with two conflicting objectives (total cost of installation and energy loss, and total non-delivered energy), the Pareto-optimality principle based tradeoff is done using the strength Pareto evolutionary algorithm-2 The efficiency of PSO for distribution system planning problem, in general, is demonstrated through different examples

TL;DR: In this article, the authors provide an end-to-end perspective from network design to optimization from a theoretical and practical perspective on the planning and optimization aspects of UMTS, and a number of other new techniques to help operators get the most out of their networks.
Abstract: UMTS Network Planning, Optimization, and Inter-Operation with GSM is an accessible, one-stop reference to help engineers effectively reduce the time and costs involved in UMTS deployment and optimization. Rahnema includes detailed coverage from both a theoretical and practical perspective on the planning and optimization aspects of UMTS, and a number of other new techniques to help operators get the most out of their networks. Provides an end-to-end perspective, from network design to optimization Incorporates the hands-on experiences of numerous researchers Single authorship allows for strong coherency and accessibility Details the complete iteration cycle of radio link budgeting for coverage planning and dimensioning Rahnema demonstrates detailed formulation of radio capacity and coverage in UMTS, and discusses the tradeoffs involved. He presents complete link budgeting and iterative simulations for capacity and coverage planning, along with practical guidelines. UMTS Network Planning contains seventeen cohesive and well-organized chapters which cover numerous topics, including: Radio channel structures, radio channel models, parameters, model tuning Techniques for capacity and coverage enhancements Complete treatment of power control, handoffs and radio resource practical management processes and parameters Detailed coverage of TCP protocol enhancement for operation over wireless links, particularly UMTS Application of GSM measurements to plan and re-engineer for UMTS radio sites Guidelines for site co-location with GSM, the QOS classes, parameters and inter-workings in UMTS AMR voice codecs and tradeoffs, core and access network design, architectural evolution, and protocols Comprehensive discussion and presentation of practical techniques for radio performance analysis, trending, and troubleshooting Perfect for professionals in the field and researchers specializing in network enhancement. Engineers working on other air interfaces and next generation technologies will find many of the techniques introduced helpful in designing and deploying future wireless networks as well. Students and professionals new to the wireless field will also find this book to be a good foundation in network planning, performance analysis, and optimization.
