Analisi comparativa delle specie esotiche e autoctone di mele stellate
La Nigeria il Paese pi popolato dell'Africa, con una popolazione stimata di oltre 170.507.539 milioni di persone; ricca di flora e fauna diverse, che forniscono materiali per il cibo, la medicina, il riparo, l'abbigliamento ecc. Con l'incessante aumento della popolazione e la crescita della produzione alimentare, la terra subisce una maggiore pressione. A ci si aggiunge la modernizzazione, che comprende la costruzione di scuole, strade, industrie/fabbriche, case, centri commerciali, bancarelle, ecc. L'incessante aumento della popolazione ha portato anche a un incremento della domanda di cibo, legno e altre materie prime. Il finanziamento degli istituti di ricerca da parte del governo non sufficiente per realizzare i progetti. Oltre che come cibo, il cibo delle nostre foreste serve anche come medicina. Molte delle difficolt incontrate nella formulazione di metodi per la conservazione delle risorse genetiche tropicali sono dovute alla mancanza di informazioni sufficienti sul valore alimentare, sulla genetica, sui metodi di propagazione appropriati, sui valori economici e medicinali di queste specie arboree; una persona non informata che non comprende l'importanza di piantare alberi consumer questi frutti senza una propagazione adeguata.

An interdisciplinary approach to understanding queueing and graphical networks In today's era of interdisciplinary studies and research activities, network models are becoming increasingly important in various areas where they have not regularly been used. Combining techniques from stochastic processes and graph theory to analyze the behavior of networks, Fundamentals of Stochastic Networks provides an interdisciplinary approach by including practical applications of these stochastic networks in various fields of study, from engineering and operations management to communications and the physical sciences. The author uniquely unites different types of stochastic, queueing, and graphical networks that are typically studied independently of each other. With balanced coverage, the book is organized into three succinct parts: Part I introduces basic concepts in probability and stochastic processes, with coverage on counting, Poisson, renewal, and Markov processes Part II addresses basic queueing theory, with a focus on Markovian queueing systems and also explores advanced queueing theory, queueing networks, and approximations of queueing networks Part III focuses on graphical models, presenting an introduction to graph theory along with Bayesian, Boolean, and random networks The author presents the material in a self-contained style that helps readers apply the presented methods and techniques to science and engineering applications. Numerous practical examples are also provided throughout, including all related mathematical details. Featuring basic results without heavy emphasis on proving theorems, Fundamentals of Stochastic Networks is a suitable book for courses on probability and stochastic networks, stochastic network calculus, and stochastic network optimization at the upper-undergraduate and graduate levels. The book also serves as a reference for researchers and network professionals who would like to learn more about the general principles of stochastic networks.

What every electrical engineering student and technical professional needs to know about data exchange across networks While most electrical engineering students learn how the individual components that make up data communication technologies work, they rarely learn how the parts work together in complete data communication networks. In part, this is due to the fact that until now there have been no texts on data communication networking written for undergraduate electrical engineering students. Based on the author’s years of classroom experience, Fundamentals of Data Communication Networks fills that gap in the pedagogical literature, providing readers with a much-needed overview of all relevant aspects of data communication networking, addressed from the perspective of the various technologies involved. The demand for information exchange in networks continues to grow at a staggering rate, and that demand will continue to mount exponentially as the number of interconnected IoT-enabled devices grows to an expected twenty-six billion by the year 2020. Never has it been more urgent for engineering students to understand the fundamental science and technology behind data communication, and this book, the first of its kind, gives them that understanding. To achieve this goal, the book: Combines signal theory, data protocols, and wireless networking concepts into one textExplores the full range of issues that affect common processes such as media downloads and online gamesAddresses services for the network layer, the transport layer, and the application layerInvestigates multiple access schemes and local area networks with coverage of services for the physical layer and the data link layerDescribes mobile communication networks and critical issues in network securityIncludes problem sets in each chapter to test and fine-tune readers’ understanding Fundamentals of Data Communication Networks is a must-read for advanced undergraduates and graduate students in electrical and computer engineering. It is also a valuable working resource for researchers, electrical engineers, and technical professionals.

Raggiungere l'uguaglianza di genere ed eliminare tutte le forme di discriminazione contro le donne sono diritti umani fondamentali e le donne di tutto il mondo subiscono regolarmente violazioni dei loro diritti umani. Negli ultimi decenni le Nazioni Unite hanno fatto progressi nel garantire i diritti delle donne a livello globale attraverso trattati, conferenze e risoluzioni. Uno di questi la Dichiarazione e la Piattaforma d'azione di Pechino del 1995. La Piattaforma d'azione ha stabilito la responsabilit dei governi nella promozione dell'uguaglianza e la Nigeria l'ha adottata insieme ad altri 188 paesi. Nel contesto della revisione venticinquennale dell'implementazione della Piattaforma d'azione di Pechino, una prospettiva storica permette una valutazione critica dei progressi fatti in Nigeria per l'avanzamento delle donne e la promozione dell'uguaglianza di genere in termini di consegna degli impegni contenuti nella Piattaforma d'azione e le lacune e gli ostacoli che dovranno essere affrontati negli anni a venire. Finora sono stati fatti passi incredibili a livello globale per raggiungere un mondo in cui ogni ragazza e donna possa avere le stesse opportunit degli uomini.
