Time will tell: behavioural scoring and the dynamics of consumer credit assessment
Full text linkThis paper discusses the use of dynamic modelling in consumer credit risk assessment. It surveys the approaches and objectives of behavioural scoring, customer scoring and profit scoring. It then investigates how Markov chain stochastic processes can be used to model the dynamics of the delinquency status and behavioural scores of consumers. It discusses the use of segmentation, mover-stayer models and the use of second and third order models to improve the fit of such models. An alternative survival analysis proportional hazards approach to estimating when default occurs is considered. Comparisons are made between the way credit risk is modelled in consumer lending and corporate lending
Single- and Multi-carrier Quadrature Amplitude Modulation: Principles and Applications for Personal Communications, WATM and Broadcasting: 2nd
No full textSingle- and Multi-carrier Quadrature Amplitude Modulation Principles and Applications for Personal Communications, WLANs and Broadcasting L. Hanzo Department of Electronics and Computer Science, University of Southampton, UK W. Webb Motorola, Arlington Heights, USA formerly at Multiple Access Communications Ltd, Southampton, UK T. Keller Ubinetics, Cambridge Technology Centre, Melbourn, UK formerly at Department of Electronics and Computer Science, University of Southampton, UK Motivated by the rapid evolution of wireless communication systems, this expanded second edition provides an overview of most major single- and multi-carrier Quadrature Amplitude Modulation (QAM) techniques commencing with simple QAM schemes for the uninitiated through to complex, rapidly-evolving areas, such as arrangements for wide-band mobile channels. Targeted at the more advanced reader, the multi-carrier modulation based second half of the book presents a research-orientated outlook using a variety of novel QAM-based arrangements. * Features six new chapters dealing with the complexities of multi-carrier modulation which has found applications ranging from Wireless Local Area Networks (WLAN) to Digital Video Broadcasting (DVB) * Provides a rudimentary introduction for readers requiring a background in the field of modulation and radio wave propagation * Discusses classic QAM transmission issues relevant to Gaussian channels * Examines QAM-based transmissions over mobile radio channels * Incorporates QAM-related orthogonal techniques, considers the spectral efficiency of QAM in cellular frequency re-use structures and presents a QAM-based speech communications system design study * Introduces Orthogonal Frequency Division Multiplexing (OFDM) over both Gaussian and wideband fading channels By providing an all-encompassing self-contained treatment of single- and multi- carrier QAM based communications, a wide range of readers including senior undergraduate and postgraduate students, practising engineers and researchers alike will all find the coverage of this book attractive

No full textLedgers of the W.T. Carter and Brother Lumber Company: An Archival Processing Project
Full text linkThe W.T. Carter and Brother Lumber Company began in 1898 and operated until 1968 when it was sold to the U.S. Plywood Corporation. The Polk County, Texas company harvested longleaf pine during a crucial period of development for the Texas economy. The lumber industry was the state’s first large scale commercial enterprise not dependent on farming and provided a model for future extractive industries in the state. The W.T. Carter and Brother Lumber Company town of Camden, Texas exemplifies rural implementations of the company town system in the Texas lumber industry. This public history thesis provides a brief history of paternalism and its impact in the development of company towns in the southern lumber industry. In addition the thesis provides an updated history of the W.T. Carter and Brother Lumber Company, its subsidiary companies, and the sawmill company town of Camden, Texas. The author discusses archival preservation and processing best practices applied to the company’s extensive collection of ledgers donated to the East Texas Research Center, a regional university archive. This work demonstrates the archival decisions making process regarding a more traditional processing method over MPLP and other archival processing techniques
