Hoy en dia vivimos en un mundo repleto de información, es decir, de datos, y no cabe duda que para interpretarlos correctamente es fundamental el conocimiento de la Estadística, que podría definirse como el arte de obtener conclusiones a partir de datos. Dirigida a estudiantes universitarios de cualquier area, esta Introduccion a la Estadistica solo exige conocimientos de algebra a nivel de enseñanza media.Su objetivo no es simplemente el de presentar conceptos y tecnicas estadisticas, sino que pretende que los futuros profesionales sepan cuando y como deben aplicar los conocimientos estadisticos y, ademas, entiendan la razon por la cual se utiliza uno en concreto en determinados casos. Para ello, los autores han realizado un gran esfuerzo a la hora de explicar las ideas que sustentan los conceptos y las tecnicas estadisticas presentadas.Las aplicaciones de la Estadistica y las distintas perspectivas de su uso se explican aqui de forma clara y concisa, y se ilustran con numerosos ejemplos y problemas de trabajo sobre una amplia variedad de temas, en su mayor parte tomados de la vida real. Para desarrollar las habilidades del lector, se proponen cientos de ejercicios y problemas de repaso que incitan a pensar.

A remarkable fact in mathematics is the accordance between algebra and geometry: since the time of Descartes it is possible to express geometric phenomena in terms of numbers. And after doing calculations with these numbers, we can draw geometric conclusions from them. However, soon it appeared that, for instance, a circle and a line outside that circle have imaginary meeting points: points that have imaginary coordinates but can not be found in the figure. Karl von Staudt found a brilliant way to visualize imaginary geometric points, lines and planes, and Felix Klein simplified and extended his method. In this book imaginary elements appear as Klein-movements in our real space. Apart from its mathematical importance, these movements may be seen as an alternative for the remarkable occurrences of complex numbers in physics, viz. quantum physics.

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.
