Software testing is traditionally seen as a difficult and time consuming activity that is hard to embed in the software development process. This book provides a different view. It explains to stakeholders how testing can add value to software development and doing business, and provides the tester with practical information. TestGoal is not just another methodology. Several good testing methodologies exist. But, like any other profession, also testing encompasses more than the simple application of a methodology.

In this article, the authors present new models of protection that allow to simulate the overcurrent relay, instantaneous overcurrent relay and differential relay by using Matlab/Simulink. Initially, a methodology that presents how to build a library, including the different models and their communication architectures. Secondly, a case study in 220 kV transmission systems is selected as an example for fault simulation and relay testing for each relay model and the coordination protection.

Present study is ascertain to elaborate the role of green supply chain management towards the suppliers’ performance. Further, the role of social capital as a potential mediator is also explored in the Thai business to business (B2B) context. Data was collected by using the survey questionnaires. Different statistical tests for measurement model and hypothesis testing respectively. Findings highlighted that suppliers’ performance both in environmental and operational terms improves due to the GSCM practices.

The purpose of this study is to develop an Interpersonal Mindfulness Scale-TR (IMS-TR) for Turkish culture. For the data collection process, four different sample groups participated in the study. To test the construct validity of the scale an exploratory factor analysis was performed. Results suggested a 13-item, two-factor solution as (1) awareness and (2) being in the moment.

The data collected using purposive sampling and Slovin formula. The hypothesis of this research is tested by multiple linier regression. The research results showed that the variable site design, informative, security and communication have a partialy significant effect to the online shopping customer satisfaction, while the convenience of shopping variable is not significant. This understandable because each online store has different system and procedure that incovenience for consumers.

Gross Domestic Product (GDP) is the sum of income for all goods and services acquired in a given time period. This study develops a model of GDP data for the state of Johor between 2005-2016 using the Logistic Growth model. Long-term GDP equilibrium values are predicted using non-linear equations and tested with different parameters. Forecasts of GDP in the near future are also presented using the appropriate parameters.

The objective of the study is to analyze existing personnel risks and develop an adaptive, universal methodology for assessing their likelihood, with further modeling of possible risk scenarios. In the framework of the study, a two-stage method for estimating the probability of occurrence of 30 personnel risks characteristic of different types of personnel flows was tested. Possible scenarios were simulated using the Scenario Manager method.

Hacker’s Challenge brings you fact-based, computer-security war stories from top researchers, consultants, incident-response specialists, and forensic analysts working in the computer-security industry today. Rather than just retelling the story, however, the book goes further—it pulls you, the reader, inside the story. As each story unfolds, you are presented with information about the incident and are looked upon to solve the case. This book is unlike any other available right now.
