Book excerpt: Use this book to prepare for the ISTQB® Certified Tester Foundation Level Performance Testing exam. The book has been designed to follow the ISTQB syllabus, covering all of the syllabus learning objectives, with additional reference material extending beyond the syllabus. The book covers an overall methodology for managing and conducting performance testing. Performance testing has often been considered a black art. In many organizations, perhaps an individual or a small group of technical staff or contractors is given the task of "load testing" an extended system, network, or application. Performance testing is like any other form of testing. It follows a defined test process that is similar to other test types. It utilizes a disciplined approach to the definition of requirements and user stories, the creation of test conditions, test cases, and test procedures. It establishes measurable goals against which the success or failure of the testing can be judged. It also requires (and this cannot be stressed highly enough) a definition and recognition of performance test failures. Readers will gain the knowledge with both content and practice questions to prepare them for the ISQTB Performance Testing exam. The book covers the performance test types, the performance testing methodology, and the steps to plan, create, and execute performance tests and analyze the results. You will: Understand the basic concepts of performance efficiency and performance testing Define performance risks, goals, and requirements to meet stakeholder needs and expectations Understand performance metrics and how to collect them Develop a performance test plan for achieving stated goals and requirements Conceptually design, implement, and execute basic performance tests Analyze the results of a performance test and communicate the implications to stakeholders Explain the process, rationale, results, and implications of performance testing to stakeholders Understand the categories and uses for performance tools and criteria for their selection Determine how performance testing activities align with the software life cycle .

Book excerpt: An Essential Reference for Intermediate and Advanced R Programmers Advanced R presents useful tools and techniques for attacking many types of R programming problems, helping you avoid mistakes and dead ends. With more than ten years of experience programming in R, the author illustrates the elegance, beauty, and flexibility at the heart of R. The book develops the necessary skills to produce quality code that can be used in a variety of circumstances. You will learn: The fundamentals of R, including standard data types and functions Functional programming as a useful framework for solving wide classes of problems The positives and negatives of metaprogramming How to write fast, memory-efficient code This book not only helps current R users become R programmers but also shows existing programmers what’s special about R. Intermediate R programmers can dive deeper into R and learn new strategies for solving diverse problems while programmers from other languages can learn the details of R and understand why R works the way it does.

Book excerpt: each your body to burn more fat to improve health and performance. The concept of Metabolic Efficiency (ME) can be applied to individuals just beginning exercise, fitness enthusiasts and the seasoned athlete. ME describes the relationship between the body's ability to use fat and carbohydrate as energy sources across a variety of exercise intensities. Being more of a "fat burner" will allow you to improve your health, reduce risk for chronic disease, lose weight and body fat, improve athletic performance and eliminate gastrointestinal (GI) distress. The second edition of Metabolic Efficiency Training: Teaching the Body to Burn More Fat has been enhanced to provide more nutrition and exercise prescription strategies for individuals of all ages, abilities and fitness/sport interests.

Download or read book Engine Testing written by A. J. Martyr and published by Elsevier. This book was released on 2012-04-18 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: Engine Testing is a unique, well-organized and comprehensive collection of the different aspects of engine and vehicle testing equipment and infrastructure for anyone involved in facility design and management, physical testing and the maintenance, upgrading and trouble shooting of testing equipment. Designed so that its chapters can all stand alone to be read in sequence or out of order as needed, Engine Testing is also an ideal resource for automotive engineers required to perform testing functions whose jobs do not involve engine testing on a regular basis. This recognized standard reference for the subject is now enhanced with new chapters on hybrid testing, OBD (on-board diagnostics) and sensor signals from modern engines. - One of few books dedicated to engine testing and a true, recognized market-leader on the subject - Covers all key aspects of this large topic, including test-cell design and setup, data management, and dynamometer selection and use, with new chapters on hybrid testing, OBD (on-board diagnostics) and sensor signals from modern engines - Brings together otherwise scattered information on the theory and practice of engine testing into one up-to-date reference for automotive engineers who must refer to such knowledge on a daily basis
Download or read book The National Fuel End use Efficiency Field Test Energy Savings and Performance of an Improved Energy Conservation Measure Selection Technique written by M.P. Ternes and published by . This book was released on 1991 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: The performance of an advanced residential energy conservation measure (ECM) selection technique was tested in Buffalo, New York, to verify the energy savings and program improvements achieved from use of the technique in conservation programs and provide input into determining whether utility investments in residential gas end-use conservation are cost effective. The technique analyzes a house to identify all ECMs that are cost effective in the building envelope, space-heating system, and water-heating system. The benefit-to-cost ratio (BCR) for each ECM is determined and cost-effective ECMs (BCR> 1.0) are selected once interactions between ECMs are taken into account. Eighty-nine houses with the following characteristics were monitored for the duration of the field test: occupants were low-income, houses were single-family detached houses but not mobile homes, and primary space- and water-heating systems were gas-fired. Forty-five houses received a mix of ECMs as selected by the measure selection technique (audit houses) and 44 served as a control group. Pre-weatherization data were collected from January to April 1988 and post-weatherization data were collected from December 1988 to April 1989. Space- and waterheating gas consumption and indoor temperature were monitored weekly during the two winters. A house energy consumption model and regression analysis were employed to normalize the space-heating energy savings to average outdoor temperature conditions and a 68 F indoor temperature. Space and water-heating energy savings for the audit houses were adjusted by the savings for the control houses. The average savings of 257 therms/year for the audit houses was 17% of the average pre-weatherization house gas consumption and 78% of that predicted. Average space-heating energy savings was 252 therms/year (25% of pre-weatherization space-heating energy consumption and 85% of the predicted value) and average water-heating savings was 5 therms/year (2% of pre-weatherization water-heating energy consumption and 17% of predicted). The overall BCR for the ECMs was 1.24 using the same assumptions followed in the selection technique: no administration cost, residential fuel costs, real discount rate of 0.05, and no fuel escalation. A weatherization program would be cost effective at an administration cost less than $335/house. On average, the indoor temperature increased in the audit houses by 0.5 F following weatherization and decreased in the control houses by 0.1 F. The following conclusions regarding the measure selection technique were drawn from the study: (1) a significant cost-effective level of energy savings resulted, (2) space-heating energy savings and total installation costs were predicted with reasonable accuracy, indicating that the technique's recommendations are justified, (3) effectiveness improved from earlier versions and can continue to be improved, and (4) a wider variety of ECMs were installed compared to most weatherization programs. An additional conclusion of the study was that a significant indoor temperature take-back effect had not occurred.
