L¿Echec n¿est pas une Malédiction, mais un Maître brise le mythe selon lequel l¿échec serait d¿origine maléfique. Ce livre remet en cause, cette pensée préconçue selon laquelle, l¿échec serait l¿opposé du succès; il explique dans un langage direct, mais simple et accessible à tous, le rôle important que joue l¿échec dans la démarche du succès.

The metaverse is like a giant virtual world where you can go and do almost anything you can imagine. It's like a big video game, but you feel like you're really there instead of just playing on a screen. You can meet other people, explore new places, and create things.Think of it like a giant playground that you can access through your computer or phone. It's a place where you can be whoever you want to be and do whatever you want to do, just like in the real world, but it's all online.This book explains the Metaverse in everyday language, and how you will benefit from it

The Eastern States Agricultural and Industrial Exposition was founded more than a century ago to promote the agricultural and industrial development of the eastern states. Held at the fairgrounds in West Springfield, Massachusetts, the inaugural event was the National Dairy Show in 1916, followed by what would become known as The Big E, the combined state fair of the six New England states: Connecticut, Massachusetts, Maine, New Hampshire, Rhode Island, and Vermont. Weathering floods, hurricanes, the Great Depression, and two world wars, it is currently one of the largest fairs in North America, with an attendance of over 1.3 million fairgoers in 2015. With photographs spanning the past century from exposition archives, area residents, and his own collection, author David Cecchi presents a fascinating visual history of what he refers to as the fair.

Our global technology had been experiencing creative technology innovation stage. Creative technology will be experiencing to increase needs in global societies. They may include on medical creative technology industry, non-man driven or electric car transport industry, online movie or listen music or reading ebooks entertainment, even robot manufacture or service industries etc. During to most of global industries need to own high creative technology to help them to improve service performance or or raise efficiencies. Hence, future creative technology industry social needs will be influenced to increase and to assist any kinds of industries development. In my this book, I shall give evidences to explain why and how what kinds of industries , which will increase creative technology industry need. Readers can bring fresh creative industries development knowledge.

Predictions of the impacts of climate change on the intensity, amount, and spatial and temporal variability of rainfall and temperature are required. The aim of this study was to assess the status of climate change and hydrological response to climate change for Gumara River sub-basin. Statistical Downscaling Model (SDSM 4.2) was used to downscale HadCM3A2a and HadCM3B2a predictors into finer scale resolution. To estimate the level of impact of climate change, climate change scenarios of precipitation and temperature were divided into four time windows of 25 years each from 2001 to 2099. The Soil and Water Assessment Tool (SWAT) was used to simulate the hydrological response. The results showed that the SWAT calibration and validation reveals a good agreement with R2 = 0.9 and NSE = 0.89 during calibration and R2 = 0.89 and NSE = 0.86 during validation. Annually, both precipitation and temperature showed increasing trends in all future time horizons in which precipitation increases up to a maximum of 13.7% (2076 to 2099) and temperature increases by 1.010c (2076 to 2099).

Arm inductor and sub-module capacitor are two key components in the modular multilevel converter. Optimizing the selections of arm inductance and sub-module capacitance is thus critical for the converters design.Arm inductors in MMC are used to limit the circulating current which flows within the converter. The switching frequency harmonic is found to be the dominant component in the circulating current when an active circulating current suppressing controller is implemented. The analytical relationship between the arm inductance and switching frequency circulating current is derived, based on which the arm inductance requirement is obtained by limiting the circulating current to meet the defined specifications. A simulation has been carried out in the MATLAB, and the simulation results verify the theoretical analysis. A scaled-down MMC prototype has been built, and the experimental results validate part of the analysis.

?A colorful page-turner.? ?Walter Isaacson, New York Times Book Review?As important a book on space as has ever been written.? ?Homer Hickam, #1 New York Times bestselling author of Rocket BoysThe dramatic inside story of the historic flights that launched SpaceX?and Elon Musk?from a shaky start-up into the world's leading-edge rocket company.SpaceX has enjoyed a miraculous decade. Less than 20 years after its founding, it boasts the largest constellation of commercial satellites in orbit, has pioneered reusable rockets, and in 2020 became the first private company to launch human beings into orbit. Half a century after the space race it is private companies, led by SpaceX, standing alongside NASA, pushing forward into the cosmos, and laying the foundation for our exploration of other worlds.But before it became one of the most powerful players in the aerospace industry, SpaceX was a fledgling start-up, scrambling to develop a single workable rocket before the money ran dry. The engineering challenge was immense; numerous other private companies had failed similar attempts. And even if SpaceX succeeded, they would then have to compete for government contracts with titans such as Lockheed Martin and Boeing, who had tens of thousands of employees and tens of billions of dollars in annual revenue. SpaceX had fewer than 200 employees and the relative pittance of $100 million in the bank.In Liftoff, Eric Berger, senior space editor at Ars Technica, takes readers inside the wild early days that made SpaceX. Focusing on the company's first four launches of the Falcon 1 rocket, he charts the bumpy journey from scrappy underdog to aerospace pioneer. We travel from company headquarters in El Segundo, to the isolated Texas ranchland where they performed engine tests, to Kwajalein, the tiny atoll in the Pacific where SpaceX launched the Falcon 1. Berger has reported on SpaceX for more than a decade, enjoying unparalleled journalistic access to the company's inner workings. Liftoff is the culmination of these efforts, drawing upon exclusive interviews with dozens of former and current engineers, designers, mechanics, and executives, including Elon Musk. The enigmatic Musk, who founded the company with the dream of one day settling Mars, is the fuel that propels the book, with his daring vision for the future of space.Filled with never-before-told stories of SpaceX's turbulent beginning, Liftoff is a saga of cosmic proportions.
