Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Research Paper (postgraduate) from the year 2019 in the subject Instructor Plans: Computing / Data Processing / IT / Telecommunication, , course: M.Tech, language: English, abstract: Fiber amplifiers are a crucial and fast-growing field in the communication system. The study of this field show that the formulation procedures of lasers generation and amplifier amplification displays a problematical process due to the factors affecting and changing amplifier and laser significance in a dynamic way.Gain, noise figure, wavelength, power flatness and power output are directly affected by any element or parameter inside the amplifier configuration. The design parameters such as: erbium ions concentration, EDF length, isolators, wavelength division multiplexing (WDM) position, pump power position, circulators, pump directions, all of these elements and factors are affecting directly the amplifier output. EDFA is an amplifier that is best used because of its low loss and high gain. For communication, there are two windows 1530-1560nm(C-band) and 1560-1610nm (L-band).

Taschenbuch. Zustand: Neu. Neuware - Celestial Love: A Collection of Poems is a mesmerizing debut book that takes readers on an ethereal journey through the vast, boundless expanse of the cosmos. In this extraordinary collection, the poet explores the most powerful force in the universe-love, through the lens of stars, moons, and galaxies. Each poem weaves a tapestry of emotions, charting a love story that transcends space and time, reaching beyond the known universe to a place where celestial beings are bound by a force greater than all earthly limitations.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Master's Thesis from the year 2019 in the subject Instructor Plans: Computing / Data Processing / IT / Telecommunication, , course: M.Tech, language: English, abstract: With the evolvement of high speed and long-distance data communication systems, conventional band erbium-doped fiber amplifiers (C-EDFAs) are getting more attention in recent times. Major advantage of the C-band EDFA is that it provides the user to realize a system with wide bandwidth of 40 nm. But, from the reported works, it is evident that for Gain enhancement in C-band using EDFA is reported with the use of multiple stages, multiple pumps, Gain flattening filters etc. However, these techniques suffered from high cost, complex techniques, and low performance. Here enhancement process was done through the narrowband Fiber Bragg Gratings (FBG) or fiber reflectors mirrors. In this work, a conventional band erbium doped fiber amplifier is proposed with high gain and less noise figure by incorporating the two fiber bragg gratings (FBGs) for amplified spontaneous noise reinjection. Maximum ASE is emerged at 1565 nm for the at -55 dBm carrier powers. Maximum gain is found out to be 48.16 dB with noise figure of 5.29 dBm. Fiber amplifiers are crucial and fast-growing field in the communication system. The study of this field show that the formulation procedures of lasers generation and amplifier amplification displays a problematical process due to the factors affecting and changing amplifier and laser significances in a dynamic way. Gain, noise figure, wavelength, power flatness and power output are directly affected by any element or parameter inside the amplifier configuration. The design parameters such as: erbium ions concentration, EDF length, isolators, wavelength division multiplexing (WDM) position, pump power position, circulators, pump directions, all of these elements and factors are affecting directly the amplifier output.

Taschenbuch. Zustand: Neu. Neuware -The introduction of arsenic, which is represented by the symbol ¿As¿ in the periodic table, is one of the heavy metals that can be found in soil, water and food. This substance is one of the xenobiotics and if it is ingested, it will have adverse health consequences. Arsenic is classified as a carcinogen. Rice, which is one of the most consumed food products in the world, has a special tendency to accumulate arsenic in itself, so the continuous consumption of rice, especially rice that has more than the permissible limit of arsenic, can cause various health problems for consumers, including cancers. Nowadays, the contamination of rice with heavy metals, especially arsenic, is a trending topic of food safety in the world. It is said that rice is the second most consumed food in the world after wheat, especially in Asian countries. Thus, evaluating the amount of arsenic in imported and local rice in order to confirm or reject their immunity is of vital value for the consumers of this product. The purpose of this research is to determine the amount of arsenic in imported and local rice and compare it with the permissible limit according to international standards.Books on Demand GmbH, Überseering 33, 22297 Hamburg 56 pp. Englisch.

Hardcover. Zustand: New. 1st Edition. Contents: Preface. Foreword. Introduction. 1. Visual culture of Islam: reflection on the art heritage of Muslim Bengal. 2. Inscriptions as a source for Islamic history. 3. Advent of Islam in Bengal and the emergence of a new system. 4. Mystical dimension of the Islamic inscriptions of Bengal. 5. Inscriptions as art in the Islamic architecture of Bengal. 6. Diversity of titles in the Islamic inscriptions of Bengal. 7. Inscriptions of the formative period of Muslim rule. 8. Inscriptions of the early Bengal sultanate. 9. Inscriptions of the Husayn Shahi sultans. 10. Inscriptions of the period of transition to mughal rule. 11. Inscriptions during the reign of mughal emperors. 12. Later inscriptions. 13. Miscellaneous inscriptions. Conclusion. Appendices. Select bibliography. Index. List of maps. Architectural inscriptions are a fascinating aspect of cultural heritage of Bengal because of their rich and diverse historical content and artistic merit. Arabic and Persian epigraphs help us understand the advent of Islam in Bengal and its gradual diffusion, which eventually transformed the region into a Muslim majority area, making Bengali Muslims the second largest linguistic group in the Islamic world. This book is an interpretive study of the Arabic and Persian inscriptions of medieval Bengal in the wider context of a rich epigraphic tradition of Bengal. While focusing on previously untapped sources, it takes a fresh look into these inscriptions and examines the inner dynamics of the social, intellectual and religious transformations of Bengal. Thus it explores many unique dimensions of Arabic and Persian inscriptions of Bengal. In addition to deciphering and editing the epigraphic texts, the information derived from them has been analysed to construct the political, administrative and cultural scenario of the period. This book also examines many newly discovered epigraphs not noticed previously. The first complete survey of the Arabic and Persian inscriptions in Bengal ever to be attempted on this outstanding scale, the book reveals the significance of epigraphy as a source for history and culture of medieval Bengal. While the book will generate immense interest for scholars in various fields especially in the academic areas such as South Asian Studies, Bengal History, Archaeological Studies of the region, common readers will also enjoy reading it lucidly for their general knowledge.

Taschenbuch. Zustand: Neu. Neuware -Brassinosteroids (BRs) are steroidal plant growth-promoting hormones occur ubiquitously in the plant kingdom. These plant steroids are essential regulators of a variety of physiological processes including organ elongation, vascular differentiation, male fertility, timing of senescence, and leaf development. BRs also regulate the expression of hundreds of genes, impact the activity of numerous metabolic pathways, and also help to control overall developmental programs leading to morphogenesis. In the recent years, studies have indicated that BRs could be exploited for conferring tolerance against various abiotic stresses, nevertheless, the high production cost of these natural plant steroids has hampered initiatives for their wide commercial use. This monograph gives an insight that how BRs could be used and which analogue is most effective to ameliorate the toxicity generated by nickel stress. This work will also facilitate a ready reference on current subject matter to the students as well as researchers alike.Books on Demand GmbH, Überseering 33, 22297 Hamburg 292 pp. Englisch.
