Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The aim of this book is to present a theoretical development of higher order statistics (HOS) and their applications in blind identification and equalization domain. We provide a description of HOS theory, then we introduce the application of HOS to identify the transmission channels. In the one hand, we present a theoretical development linking cumulants and impulse response channels. In the other hand, these relationships are used to develop several algorithms. Finally, to assess the performance of these approaches to identify the parameters of communications channels, we consider theoretical channel models. One ends with simulation results illustrating the performance of the proposed methods. In the part of the implementation of HOS in blind equalization problem, we have checked the effectiveness of the proposed algorithm on a Multi-Carrier Code Division Multiple Access (MC-CDMA), for this we have chosen fast fading channels called BRAN. In this context, we use the equalizers techniques after channel identification to correct channel distortion. Theoretical analysis and numerical simulation results in noisy environment show that the proposed algorithm reduces the bit error rate. …

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Nowadays, phytotherapy is considered by many scientists as the ancestor and the basis of the actual medicine. This old discipline rely in the pharmacological properties of plants to treat various diseases and conditions and supported human beings in all aspect throughout their evolution which allowed several civilizations to develop several remedies, for example to treat wounds, problems related to gastrointestinal transit and even poison. The different plant species that compose Asteraceae family contribute in several sectors, especially in gastronomy, cosmetics and medicine. Indeed, Centaurea is considered an important genus in this family and several phytocompounds contained in Centaurea species are considered nowadays a reference for pharmaceutical industries to develop new drugs with fewer side effects. However, several mechanisms remain ambiguous for scientific community to clearly explain the pharmacological properties of secondary metabolites of plants in order to fully exploit this natural resource. The objective of this book is to summarize and valorize the phytochemical and pharmacological properties of some Centaurea species previously studied.…

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Biotechnology is about understanding how living organisms function at the molecular level. In its simplest form, biotechnology is a biology-based technology that harnesses cellular and biomolecular processes to develop technologies and products that help improve our lives and the health of our planet. We have been using the biological processes of microorganisms for over 6,000 years to make useful food products, such as bread and cheese, and to preserve dairy products. As a result, modern biotechnology is providing revolutionary products and technologies to fight debilitating and rare diseases, reduce our environmental footprint, feed the poor, use less energy, be more ecosystem friendly, and have safer, cleaner and more efficient industrial manufacturing processes. The impact of biotechnology is therefore important in the health industry, but it also extends to other areas such as the environment, agriculture and even industry.…

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - La biotecnología consiste en comprender cómo funcionan los organismos vivos a nivel molecular. En su forma más simple, la biotecnología es una tecnología basada en la biología, que explota los procesos celulares y biomoleculares para desarrollar tecnologías y productos que ayuden a mejorar nuestras vidas y la salud de nuestro planeta. Llevamos más de 6.000 años utilizando los procesos biológicos de los microorganismos para elaborar productos alimentarios útiles, como el pan y el queso, y para conservar los productos lácteos. Así, la biotecnología moderna proporciona productos y tecnologías revolucionarias para combatir enfermedades debilitantes y raras, reducir nuestra huella medioambiental, alimentar a los pobres, utilizar menos energía, ser más respetuosos con el ecosistema y tener procesos de fabricación industrial más seguros, limpios y eficientes. El impacto de la biotecnología es, por tanto, importante en la industria de la salud, pero también se extiende a otros ámbitos como el medio ambiente, la agricultura e incluso la industria.…
