Bøger af David Johnston

A teacher book that supports teachers and technicians in delivery of the required practicals, complete with answers to the student book questions, safety guidance and non-specialist information.

A workbook-style Lab Book to allow students to record their completion of the required practicals, as well as giving them additional practice through exam-style questions.

Provide full coverage of the required practicals and build students' working scientifically skills with questions that enable them to apply their knowledge to new contexts. - Extend knowledge and build working scientifically skills with 'Further Application' sections that provide additional questions to allow students to practice applying their knowledge. - Help guide students through the practical, the analysis of results, and generating a reasoned conclusion with scaffolded questions. - Get exam ready with exam-style questions, guidance on how practicals are assessed, a list of useful equations, and a checklist to monitor progress. - Cover all the required practicals with methods provided, complete with safety notes and guidance on equipment.

Random Number Generators, Principles and Practices has been written for programmers, hardware engineers, and sophisticated hobbyists interested in understanding random numbers generators and gaining the tools necessary to work with random number generators with confidence and knowledge. Using an approach that employs clear diagrams and running code examples rather than excessive mathematics, random number related topics such as entropy estimation, entropy extraction, entropy sources, PRNGs, randomness testing, distribution generation, and many others are exposed and demystified. If you have ever Wondered how to test if data is really random Needed to measure the randomness of data in real time as it is generated Wondered how to get randomness into your programs Wondered whether or not a random number generator is trustworthy Wanted to be able to choose between random number generator solutions Needed to turn uniform random data into a different distribution Needed to ensure the random numbers from your computer will work for your cryptographic application Wanted to combine more than one random number generator to increase reliability or security Wanted to get random numbers in a floating point format Needed to verify that a random number generator meets the requirements of a published standard like SP800-90 or AIS 31 Needed to choose between an LCG, PCG or XorShift algorithm Then this might be the book for you.

Exam board: AQA Level: GCSESubject: ScienceFirst teaching: September 2016First exams: Summer 2018 All the support you need to teach the AQA GCSE Science (9-1) required practicals (covers separate sciences and Combined Science) with technician notes, model results, advice on common student mistakes and additional experiments to extend knowledge. - Provides full coverage with technician notes for every core practical, complete with equipment lists and safety notes. - Offers guidance around possible causes for different kinds of anomalous results for each experiment. - Highlights common student mistakes with explanations on how to address them. - Helps provide a holistic approach to teaching practicals with suggested variations on the core practicals, linked experiments and extension experiments. The Teacher Books include answers to all of the questions in the accompanying Lab Workbooks, complete with mark schemes and with extension and maths questions flagged.

This new book by academic David Johnson, on the Spanish 'Golden Age' plays argues for the importance of these plays place in history, as well as on the British stage.

Offers both clinicians and researchers guidance on hazard preparation efforts as well as early response and intervention practices. This title emphasizes an evidence- and prevention-based approach that is geared toward readiness, response, and recovery phases of natural and human-made disasters.

A look at Lorca's ambivalent view of his own homosexuality as expressed through his life and his art.
