Optimal Precision Relay: 21st Century Bidding Card-playing technique at Bridge has reached, for quite some time now, a very advanced and scientific level. That is not the case when it comes to bidding! Much of the work devoted to bidding over the years has mostly focused on trying to find specific remedies to specific deficiencies. But just tweaking traditional bidding is not the solution, as it cannot and never will achieve satisfactory results, as it is based on a "dialogue" by which each partner describes part of his hand to the other, and that partial description is hopelessly inadequate and insufficient to reach the optimal contract. The solution is elsewhere and requires rethinking the way partners communicate. The dialogue needs to be replaced by a "monologue," by which one partner asks the other to fully describe his hand through successive, economical relay bids. In this book, the author presents a new bidding methodology which fully integrates the relay process into a bidding method. Based on the Optimal Hand Evaluation point count, it counts opening hands in HLD points and opens 1 strong Club hands of 18+ HLD points, which limits every other opening to 17 HLD points. The method reverses the traditional process of using jumps to describe maximum hands by using "braking" bids to describe minimum hands. This enables a much more economical description of the hand and 12 of its 13 cards at the level of three! It extends the use of transfer responses to all openings of one, allowing them to precisely describe responding hands through economical rebids in various point zones. Optimal Precision Relay is a fully developed relay bidding method, proposing novel solutions that will be of interest to many readers.

My goal for “The Modified Optimal 2/1-Club System” is to show how to use the Optimal Point Count (OPC) method of hand evaluation developed by Patrick. Darricades in his book “Optimal Hand Evaluation” (2019) to improve the dialogue between two players to achieve an optimal bridge contract. The primary objective is to demonstrate how to apply the new system approach to contract bridge by illustrating a more accurate method of hand evaluation whether you play 2/1, Standard American (SA), Acol or Precision, among others. The Two over One (2/1) Game Force bidding system was an improvement over the SA System that has been in effect and played by bridge players for many years. Many claim that the advantage of the 2/1 system allows the partnership to know that game is possible with only a single bid provided one has 13+ points. As we shall see for suit contracts it is only true if the opening 2/1 bidder has 15 points, not 12/13 points since 25/26 points do not result in game whenever a singleton in one hand finds “wasted honor points” in partner’s hand. Yet, most 2/1 conventions call for 13+ High Card Points (HCP). Another flaw of the 2/1 approach is the fact that opening 1-level suit bids have a wide bidding range (12-21). To eliminate this flaw, the principles of Pinpoint Precision with 1*= 18+ points and new responses associated with a new and improved hand evaluation method. A major flaw of most Strong Club opening bids is that they are based solely on HCPs with opening bids of 1*=16/17+ HCP. To correct these flaws among others, the search for a better hand evaluation method and a better bidding system has been unrelenting. Hand evaluation methods have been popularized by Milton Work, Charles Goren, Marty Bergen, and Petkoy Zar, and others. All falling short when applied to the commonly used “dialogue” bidding systems. The Optimal Point Count (OPC) method of hand evaluation corrects the many flaws of prior hand evaluation methods when applied to any bidding system. In this book many “traditional/standard” bidding practices that do not help to show suit fi t and distribution are to be avoided or re-defined. Splinters and mini splinters which show the location of voids and singletons to help locate wasted honors, the XYZ bidding convention, cue bidding, and new bids for the investigation of game and slam are among the cornerstone conventions reviewed in this book. Newly defined 2 and 3-level bids to show hands with 6/7+card suits are defined to prevent the opponents from finding their optimal contract and to improve upon difficult bidding sequences using traditional bidding strategies. The evaluation of one’s Offense to Defense Ratio (ODR), why many well-known bidding sequences must be avoided, and an analysis of several old “standard” bridge laws/rules are reviewed to show why they need not be used to improve one’s judgement if one employs the OPC method.

In this book, three different methods are presented to enhance the capacity and coverage area in LTE-A cellular networks. The scope involves the evaluation of the effect of the RN location in terms of capacity and the determination of the optimum location of the relay that provides maximum achievable data rate for users with limited interference at the cell boundaries. This book presents a new model to enhance both capacity and coverage area in LTE-A cellular network by determining the optimum location for the RN with limited interference. The new model is designed to enhance the capacity of the relay link by employing two antennas in RN. This design enables the relay link to absorb more users at cell edge regions. An algorithm called the Balance Power Algorithm (BPA) is developed to reduce MR power consumption. The book pertains to postgraduate students and researchers in wireless & mobile communications.

An Application-Oriented Introduction to Essential Optimization Concepts and Best Practices Optimization is an inherent human tendency that gained new life after the advent of calculus; now, as the world grows increasingly reliant on complex systems, optimization has become both more important and more challenging than ever before. Engineering Optimization provides a practically-focused introduction to modern engineering optimization best practices, covering fundamental analytical and numerical techniques throughout each stage of the optimization process. Although essential algorithms are explained in detail, the focus lies more in the human function: how to create an appropriate objective function, choose decision variables, identify and incorporate constraints, define convergence, and other critical issues that define the success or failure of an optimization project. Examples, exercises, and homework throughout reinforce the author’s “do, not study” approach to learning, underscoring the application-oriented discussion that provides a deep, generic understanding of the optimization process that can be applied to any field. Providing excellent reference for students or professionals, Engineering Optimization: Describes and develops a variety of algorithms, including gradient based (such as Newton’s, and Levenberg-Marquardt), direct search (such as Hooke-Jeeves, Leapfrogging, and Particle Swarm), along with surrogate functions for surface characterization Provides guidance on optimizer choice by application, and explains how to determine appropriate optimizer parameter values Details current best practices for critical stages of specifying an optimization procedure, including decision variables, defining constraints, and relationship modeling Provides access to software and Visual Basic macros for Excel on the companion website, along with solutions to examples presented in the book Clear explanations, explicit equation derivations, and practical examples make this book ideal for use as part of a class or self-study, assuming a basic understanding of statistics, calculus, computer programming, and engineering models. Anyone seeking best practices for “making the best choices” will find value in this introductory resource.

With ample coverage of preamplifiers and mixers and a new chapter on headphone amplifiers, this practical handbook provides an extensive repertoire of circuits that can be put together to make almost any type of audio system. A resource packed full of valuable information, with virtually every page revealing nuggets of specialized knowledge not found elsewhere. Essential points of theory that bear on practical performance are lucidly and thoroughly explained, with the mathematics kept to a relative minimum. Douglas' background in design for manufacture ensures he keeps a wary eye on the cost of things. Includes a chapter on power-supplies, full of practical ways to keep both the ripple and the cost down, showing how to power everything. Douglas wears his learning lightly, and this book features the engaging prose style familiar to readers of his other books.
