This book was released on 2018-12-28 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a collection of seven in-depth and detailed research papers authored by Dr. Raman K Attri between 1996 to 2005. The book presents early-career scientific work by the author as a scientist at a research organization. The book provides the conceptual background and key electronics and mechanical design principles used in designing sensors and instrumentation systems to measure snow hydrological parameters. The systems discussed in this book can be used to measure snow depth, layer temperature, temperature distribution profile, surface porosity, etc. The snow parameters measured from instruments and sensors discussed in this book are integrated into larger systems and are used in computer-driven models for snow avalanche predictions. The book presents the design challenges and design methods from electronics and instrumentation design point of view. While the book provides essential understanding of analog electronics design and associated mechanical design for snow hydrological sensors, the book also presents the background theoretical and mathematical models from snow hydrology physics that governs this electronics design. The first research paper discusses the design control techniques used to the design a remote surface detector to detect objects with porous, uneven, irregular surfaces like snow using ultrasonic beams. The second research paper describes signal processing techniques and electronics design approaches to design a snow depth sensor with improved sensitivity and directional response using Ultrasonic Pulse-Transit Method. The third research paper explains theoretical and mathematical model that governs the physical, mechanical, and electronics design to implement the theory of Arrayed Ultrasonic transducers to shape up the directional response and beam width of an ultrasonic beam to improve the chances of receiving sufficient reflection from the non-smooth, highly porous, uneven, non-planar, irregular snow surface. The fourth paper presents the design considerations and performance characteristics of Snow Temperature Profile Sensing System used to measure the temperature gradient and temperature distributions within and outside the snowpack at different depths. The fifth research paper focuses on describing the design of Snow Temperature Profile Sensing System in details and discusses the theoretical and mathematical model that outline important temperature parameters. Then the paper describes how the system is implemented to record or measure those parameters. The sixth paper presents the design considerations, constraints and design techniques used to use RTD temperature sensors for snow temperature measurement applications. The paper also presents the performance evaluation and suitability of such sensors. The seventh paper focuses design techniques for front-end analog signal conditioning module and the design challenges faced when interfacing analog unit to a data acquisition system. The eighth paper describes the design of snow air temperature sensing probe and methods to ensure that it measures true air temperature over a snow cover and is not influenced by solar radiations and winds. The book may be read as an applied text-book in conjunction with standard electronics and instrumentation design textbooks. The book will guide students on how to apply basic principles of instrumentation systems design, integrate concepts of physical sciences and measurement sciences for the field applications.

Download or read book Seismic Instrumentation Design written by Raman K. Attri and published by Speed To Proficiency Research: S2Pro©. This book was released on 2018-11-21 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a collection of three papers authored by Dr. Raman K Attri between 1999 to 2001. The book presents early-career scientific work by the author as a scientist at a research organization. The book provides a theoretical and conceptual understanding of concepts and principles for detection and measurements of the seismic signals. The earthquake phenomenon is one of the most unpredictable and often devastating natural events. Sophisticated and advanced technologies are being used for monitoring the seismic activities across the world and efforts are being put in place to develop prediction models. The theory behind the design of sensors, instrumentation and monitoring system is usually not known to electronics and software engineers upfront. The papers included in this book provide such basic guidance to electronics and software design engineers and equip them with the key computational and algorithmic principles based on the underlying theory of seismic activities. These design techniques are fundamental to designing sophisticated seismic instrumentation and earthquake monitoring systems. The first paper presents a simplified mathematical framework of the seismic events and backend computational software logic that will enable software engineers to develop a customized seismic analysis and computation software. The second paper presents a simplified description of various earthquake parameters of interest to a seismologist and how these complex parameters are computed using equations. In the third paper, a visionary concept is presented to integrate geo-scientific instrumentation equipment such as seismic measurement systems to information technology network that would create a centralized web-enabled database that would allow transmitting the data acquired by geographically distributed but networked observatories to better predict or alert about the phenomena like earthquakes.

Available in PDF, EPUB and Kindle. Book excerpt: Principles of Snow Hydrology describes the factors that control the accumulation, melting and runoff of water from seasonal snowpacks over the surface of the earth. The book addresses not only the basic principles governing snow in the hydrologic cycle, but also the latest applications of remote sensing, and techniques for modeling streamflow from snowmelt across large mixed land-use river basins. Individual chapters are devoted to climatology and distribution of snow, snowpack energy exchange, snow chemistry, ground-based measurements and remote sensing of snowpack characteristics, snowpack management, and modeling snowmelt runoff. Many chapters have review questions and problems with solutions available online. This book is a reference book for practicing water resources managers and a text for advanced hydrology and water resources courses which span fields such as engineering, earth sciences, meteorology, biogeochemistry, forestry and range management, and water resources planning.
