Retirement Planning: 401k vs Roth 401k, IRA vs Roth IRA, Outskirts Press, Denver, Colorado, 2020.
Quantitative Analysis of 401(k) vs Roth 401(k), IRA vs Roth IRA, and Roth Conversion. This book aims to provide a comprehensive analysis, with data simulations, of: 1) when investing in a Roth 401(k) or Roth IRA would be a better choice than investing in a traditional pretax 401(k) or IRA; 2) when a Roth conversion would be beneficial to an investor.

The hope is that an investor can utilize the formulas and data contained in this book when making strategic decisions on choosing between a Roth 401(k) and pretax 401(k) or between a Roth IRA and traditional IRA, or deciding whether to do a Roth conversion.
 
Java Persistence with JPA 2.1, Outskirts Press, Denver, Colorado, 2013.
The goal of this book is to provide a concise and comprehensive coverage of Java Persistence API 2.1, which is part of Java EE 7 but can be used in Java SE as well. Concepts are illustrated through code examples for easy understanding. It may serve as an introductory text for Java developers who do not know anything about JPA, and a reference book for experienced JPA developers who may look up for concepts and code snippets while they develop complex JPA applications.
 
Java Persistence with JPA, Outskirts Press, Denver, Colorado, 2010.
Concise and complete coverage of Java Persistence API 2.0 with code examples, design patterns, and performance tuning tips. It is Java EE 6.0 compliant, but can be used in Java SE 5.0 and Java EE 5.0 or later. It is written for Java developers and architects to learn everything about JPA and use it as a reference book.
 
C++ and Object Oriented Numeric Computing for Scientists and Engineers, Springer-Verlag, New York, 2001 (paperback 2012; Chinese translation 2002).
Concise and complete coverage of ANSI/ISO C++, with special emphasis on object-oriented numeric computing through numerical algorithms and code examples
