This book will take you on a whirlwind tour of full-stack web application development using Raspberry Pi. You will learn how to build an application from the ground up.You will gain experience and know-how of technologies including:- The Linux operating system and command line.- The Python programming language.- The Raspberry Pi General Purpose Input Output pins (GPIOs).- The Nginx web server.- Flask Python web application microframework.- JQuery and CSS for creating user interfaces.- Dealing with time zones.- Creating charts with Plotly and Google Charts.- Data logging with Google Sheet.- Developing applets with IFTTT.- Securing your application with SSL.- Receiving SMS notifications to your phone using Twilio.This book will also teach you how to set up a remote wireless Arduino sensor node and collect data from it. Your Raspberry Pi web application will be able to process Arduino node data in the same way it processes data from its onboard sensor.Raspberry Pi Full Stack will teach you many skills essential to building Web and Internet of Things applications.The application you will build in this project is a platform that you can extend upon. This is just the start of what you can do with a Raspberry Pi and the software and hardware components that you will learn about.This book is supported by the author via a dedicated discussion space.

Ever since the Raspberry Pi was introduced, it has been used by enthusiasts to automate their homes. The Raspberry Pi is a powerful computer in a small package, with lots of interfacing options to control various devices. This book shows you how you can automate your home with a Raspberry Pi. Youll learn how to use various wireless protocols for home automation, such as Bluetooth, 433.92 MHz radio waves, Z-Wave, and Zigbee. Soon youll automate your home with Python, Node-RED, and Home Assistant, and youll even be able to speak to your home automation system. All this is done securely, with a modular system, completely open-source, without relying on third-party services. Youre in control of your home, and no one else.At the end of this book, you can install and configure your Raspberry Pi as a highly flexible home automation gateway for protocols of your choice, and link various services with MQTT to make it your own system. This DIY (do it yourself) approach is a bit more laborious than just installing an off-the-shelf home automation system, but in the process, you can learn a lot, and in the end, you know exactly whats running your house and how to tweak it. This is why you were interested in the Raspberry Pi in the first place, right?- Turn your Raspberry Pi into a reliable gateway for various home automation protocols. - Make your home automation setup reproducible with Docker Compose. Secure all your network communication with TLS.- Create a video surveillance system for your home.- Automate your home with Python, Node-RED, Home Assistant and AppDaemon.- Securely access your home automation dashboard from remote locations.- Use fully offline voice commands in your own language.

The Internet of Things (IoT) is becoming a major application area for embedded systems. As a result, more and more people are becoming interested in learning about embedded design and programming. Technical colleges and universities are moving away from legacy 8 and 16-bit microcontrollers and are introducing 32-bit embedded microcontrollers to their curriculums. Many IoT applications demand precision, high processing power, and low power consumption.Produced by IBM, Node-RED is an open-source visual editor for wiring the Internet of Things. Node-RED comes with a large number of nodes to handle a multitude of tasks. The required nodes are selected and joined together to perform a particular task. Node-RED is based on flow type programming where nodes are configured and joined together to form an application program. There are nodes for performing complex tasks, including web access, Twitter, E-mail, HTTP, Bluetooth, MQTT, controlling GPIO ports, etc. One particularly nice aspect of Node-RED is that the programmer does not need to learn how to write complex programs. For example, an email can be sent by simply joining nodes together and writing only a few lines of code.The aim of this book is to teach how Node-RED can be used in projects. The main hardware platform used with most of the projects in this book is Raspberry Pi 4. Chapters are included to show how Node-RED can be also be used with Arduino Uno, ESP32 DevKitC, and the ESP8266 NodeMCU microcontroller development boards.

Este es un texto que contiene una exposición axiomática de la teoría general de espacios vectoriales topológicos y trata con profundidad algunos aspectos de la teoría y, asimismo, muestra varios ejemplos interesantes de aplicacion a otras ramas de la Matematica.

This book captures the excitement of a formative phase of UK science during and immediately following WWII. It links back to scientists working at Antarctic whaling stations and the complimentary voyages of Captain Scotts Discovery that explored the vast icy Southern Ocean, funded by a tax on whale oil. In the depths of WWII a small group of young scientists were brought together under the inspirational leadership of Dr (later Sir) George Deacon, and shortly after the end of the war, the UKis first National Institute of Oceanography was formed. The discoveries from 50 years ago underpin our modern-day science. The bookis chapters are all written and edited by NIO scientists and convey the atmosphere of work at sea in a bygone age before small computers,satellite navigation and easy communication. The book is A useful introduction for students of marine and/or environmental science. It will appeal to many scientists and the general public , to those interested in science and innovation during and after WWII and of course to many living in the Surrey who always wondered what went on in the leafy lanes that were home to NIO and its successors for almost 50 years.

El herpes zóster (HZ) es una enfermedad que acompaña desde antiguo a la humanidad, si bien es cierto que los clásicos no diferenciaban entre herpes zóster y otras enfermedades eruptivas de la piel en sus escritos. No fue hasta finales del s. XVIII cuando se establecio una forma de diferenciar el herpes zoster de la viruela, y a finales del siglo XIX se distinguio de la erisipela.El HZ esta causado por el virus herpes tipo 3 o virus varicela-zoster (VVZ), uno de los ocho virus conocidos de la familia Herpesviridae. Tiene distribucion mundial y la susceptibilidad es universal. El unico reservorio es el ser humano, y la transmision se produce de persona a persona por contacto directo a traves de la piel, por via respiratoria o por via conjuntiva.Se produce por la reactivacion endogena del VVZ. Es decir, para desarrollar un HZ, es preciso haber sufrido una primoinfeccion, generalmente en la infancia, que aparecera en forma de varicela (clinica o subclinica). Una vez superada la primoinfeccion, el VVZ queda acantonado en los ganglios sensitivos hasta su eventual reactivacion.

Este libro está dirigido a los estudiantes que se inician en el Cálculo Diferencial e Integral, tanto a aquéllos que necesitan sobre todo un aprendizaje práctico (Escuelas Técnicas y Ciencias Aplicadas), como a los que requieren un conocimiento mas teorico y profundo. Su contenido abarca todos los temas basicos del Analisis Matematico: sistemas numericos, funciones elementales, sucesiones y series numericas, limites y continuidad de funciones, sucesiones y series funcionales, derivacion, integracion de Riemann (propia e impropia).

Texto ideado para un curso preuniversitario con una visión general de la Química y que está exento de las limitaciones que imponen las barreras de sus ramas principales como son la Química física, inorganica, organica y analitica, si bien es una adecuada introduccion al estudio de las mismas.

El objetivo de la presente obra es exponer una visión global sobre las características y la utilización de los abonos, así como numerosas recomendaciones para el abonado de los cultivos. Se ha planteado dentro de un amplio marco, que incluye muchos aspectos marginales, de los productos cosechados. Las cuestiones mas importantes y problematicas se tratan cientificamente, pero tambien se resumen de forma simplificada, cuando ello es posible y necesario.

Esta obra es un texto de enseñanza. Su finalidad es la de presentar un panorama de los objetos, métodos y técnicas de la Geología así como de los conceptos teóricos actuales que se extraen.
