Описание: A collection of articles on recent complexity developments in numerical optimization. The topics covered include complexity of approximation algorithms, new polynomial time algorithms for convex quadratic minimization and interior point algorithms.
Описание: Data Correcting Approaches in Combinatorial Optimization focuses on algorithmic applications of the well known polynomially solvable special cases of computationally intractable problems. The purpose of this text is to design practically efficient algorithms for solving wide classes of combinatorial optimization problems. Researches, students and engineers will benefit from new bounds and branching rules in development efficient branch-and-bound type computational algorithms. This book examines applications for solving the Traveling Salesman Problem and its variations, Maximum Weight Independent Set Problem, Different Classes of Allocation and Cluster Analysis as well as some classes of Scheduling Problems. Data Correcting Algorithms in Combinatorial Optimization introduces the data correcting approach to algorithms which provide an answer to the following questions: how to construct a bound to the original intractable problem and find which element of the corrected instance one should branch such that the total size of search tree will be minimized. The PC time needed for solving intractable problems will be adjusted with the requirements for solving real world problems.

Описание: Mathematical techniques, both continuous and discrete, are playing an increasingly important role in understanding several fundamental problems in medicine.For instance, the mathematical theory of nonlinear dynamics and discrete optimization has been used to predict epileptic seizures. Discrete optimization techniques and measures derived from the theory of nonlinear dynamics are used for prediction of impending epileptic seizures from analysis of multi-electrode electroencephalographic (EEG) data. Several examples of the use of mathematics in medicine can also be found in recent cancer research. Sophisticated mathematical models and algorithms have been used for generating treatment plans for radionuclide implant and external beam radiation therapy. With Gamma Knife treatment, for example, optimization techniques have been used to automate the treatment planning process. Optimization has also been used to address a variety of medical image registration problems.The work grew out of a workshop on optimization which was held during the 2005 CIM Thematic Term on Optimization in Coimbra, Portugal. It provides an overview of the state-of-the-art in optimization in medicine and will serve an excellent reference for researchers in the medical computing community and those working in applied mathematics and optimization.
Описание: This book is a complete and practical guide to WCDMA/UMTS cellular network deployment. After introducing the network architecture of such a system, the
"WCDMA (UMTS) Deployment Handbook" defines the coverage and capacity concepts associated with the dimensioning and design phases. Progressing to a discussion of the main
system parameters associated with network optimization and detailing optimization techniques for the main services supported by UMTS, and includes the specifics of indoor deployment
and HSDPA networks evolution.
This book covers all stages from planning to optimization with sufficient details as required on a day-to-day basis, and thorough reference
information for the reader who wants to understand the concepts in more detail. It is relevant for daily tasks: the approach taken in this book is similar to the work flow of network planner
and optimization engineers, allowing such personnel to easily find the relevant information. It is written by the company which made CDMA a household name: Qualcomm was the first
company to use CDMA technology for cellular application and is a technical leader in this domain.
It is based on industry feedback: all the contributors to this book have
been working in direct interaction with WCDMA operators, throughout the world, since the early days of WCDMA commercial deployment. It looks to the future: this book addresses the
next level of challenge that WCDMA operators will face - deployment of indoor systems and HSDPA. Providing a complete introduction and reference guide to everything associated
with the life cycle of a WCDMA/UMTS cellular network, from initial dimensioning through to the successful deployment of indoor solutions, or migration to HSDPA, this book is a
must-have for network planners and optimization engineers as well as telecommunication engineering students.
Описание: This title assesses dose of the representative person for the purpose of radiation protection of the public. The Commission intended that its revised
recommendations should be based on a simple, but widely applicable, system of protection that would clarify its objectives and provide a basis for the more formal systems needed by
operating managers and regulators. The recommendations would establish quantified constraints, or limits, on individual dose from specified sources.
These dose constraints
apply to actual or representative people who encounter occupational, medical, and public exposures. This report updates the previous guidance for estimating dose to the public.Dose
to the public cannot be measured directly and, in some cases, it cannot be measured at all. Therefore, for the purpose of protection of the public, it is necessary to characterise an
individual, either hypothetical or specific, whose dose can be used for determining compliance with the relevant dose constraint.
This individual is defined as the
'representative person'. The Commission's goal of protection of the public is achieved if the relevant dose constraint for this individual for a single source is met and radiological
protection is optimised. This report explains the process of estimating annual dose and recognises that a number of different methods are available for this purpose.
methods range from deterministic calculations to more complex probabilistic techniques.In addition, a mixture of these techniques may be applied. In selecting characteristics of the
representative person, three
mportant concepts should be borne in mind: reasonableness, sustainability, and homogeneity. Each concept is explained and examples are provided to illustrate their roles.
Doses to the public are prospective (may occur in the future) or retrospective (occurred in the past). Prospective doses are for hypothetical individuals who may or may not exist in the
future, while retrospective doses are generally calculated for specific individuals.The Commission recognises that the level of detail afforded by its provision of dose coefficients for six
age categories is not necessary in making prospective assessments of dose, given the inherent uncertainties usually associated with estimating dose to the public and with identification
of the representative person. It now recommends the use of three age categories for estimating annual dose to the representative person for prospective assessments.
These categories are 0-5 years (infant), 6-15 years (child), and 16-70 years (adult). For practical implementation of this recommendation, dose coefficients and habit data for a 1-year-old
infant, a 10-year-old child, and an adult should be used to represent the three age categories. In a probabilistic assessment of dose, whether from a planned facility or an existing
situation, the Commission recommends that the representative person should be defined such that the probability is less than about 5 per cent that a person drawn at random from the
population will receive a greater dose.
If such an assessment indicates that a few tens of people or more could receive doses above the relevant constraint, the
characteristics of these people need to be explored. If, following further analysis, it is shown that doses to a few tens of people are indeed likely to exceed the relevant dose constraint,
actions to modify the exposure should be considered. The Commission recognises the role that stakeholders can play in identifying characteristics of the representative
Involvement of stakeholders can significantly improve the quality, understanding, and acceptability of the characteristics of the representative person and the resulting
estimated dose.The optimisation of radiological protection: Broadening the process - The principle of optimisation of radiation protection is defined by the Commission as
