This book was released on 2018-09-23 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Siting Criteria for Hf Communication Centers Electrical and topographical characteristics of terminal sites are of considerable importance in their effects on radio propagation, and reception, for long-range ionospheric communication. It is the purpose of this report to provide an engineering guide for the siting of such radio terminals based on the current state of knowledge of propagation factors and communication techniques. Aspects of siting such as ground conductivity and dielectric constant; Fresnel zone requirement, size and clearance; ambient noise level, vertical angle of radiation; and other factors for an ideal site will be considered and standards to guide compromises for practical circumstances will be given.

This book was released on 2018-08-03 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Occupational exposure to heat can result in injuries, disease, reduced productivity, and death. To address this hazard, the National Institute for Occupational Safety and Health (NIOSH) has evaluated the scientific data on heat stress and hot environments and has updated the Criteria for a Recommended Standard: Occupational Exposure to Hot Environments [NIOSH 1986a]. This updated guidance includes information about physiological changes that result from heat stress, and relevant studies such as those on caffeine use, evidence to redefine heat stroke, and more.

Download or read book Software Defined Radio for Engineers written by Alexander M. Wyglinski and published by Artech House. This book was released on 2018-04-30 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the popular Artech House classic, Digital Communication Systems Engineering with Software-Defined Radio, this book provides a practical approach to quickly learning the software-defined radio (SDR) concepts needed for work in the field. This up-to-date volume guides readers on how to quickly prototype wireless designs using SDR for real-world testing and experimentation. This book explores advanced wireless communication techniques such as OFDM, LTE, WLA, and hardware targeting. Readers will gain an understanding of the core concepts behind wireless hardware, such as the radio frequency front-end, analog-to-digital and digital-to-analog converters, as well as various processing technologies. Moreover, this volume includes chapters on timing estimation, matched filtering, frame synchronization message decoding, and source coding. The orthogonal frequency division multiplexing is explained and details about HDL code generation and deployment are provided. The book concludes with coverage of the WLAN toolbox with OFDM beacon reception and the LTE toolbox with downlink reception. Multiple case studies are provided throughout the book. Both MATLAB and Simulink source code are included to assist readers with their projects in the field.
Download or read book Guidelines for the management of symptomatic sexually transmitted infections written by World Health Organization and published by World Health Organization. This book was released on 2021-07-15 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The WHO global health sector strategy on sexually transmitted infections, 2016–2021, endorsed by the World Health Assembly in 2016, aims to eliminate STIs as a public health threat by 2030. In 2019, WHO published estimates of new cases of chlamydia, gonorrhoea, syphilis and trichomoniasis. Recent changes in the epidemiology of STIs and progress in prevention, diagnosis and treatment of STIs and HIV have necessitated changes in approaches to STI prevention and management. To address these STIs, the most widely used approach in clinical settings is the syndromic management of STIs. In most resource-limited settings, the syndromic management flow charts are still the standard of care where laboratory diagnosis is not available or is hard to access. The objectives of these guidelines are to provide updated, evidence-informed clinical and practical recommendations on the case management of people with symptoms of STIs; and to support countries in updating their national guidelines for the case management of people with symptoms of STIs. These guidelines include the management of symptomatic infections related to urethral discharge syndrome, including persistent urethral discharge syndrome; vaginal discharge syndrome, including persistent vaginal discharge; anorectal infection; genital ulcer disease syndrome; and lower abdominal pain syndrome. These guidelines are intended for programme managers for STI prevention and control at the national level and the health-care providers at the frontline – primary, secondary and tertiary health care.
