Dass die Energiewende wichtig ist, darin besteht spätestens seit der Veröffentlichung der EU-Klimaberichte die internationale Einigkeit. Jedoch sind die Pfade der Energiewende auch heute noch ein Auslöser für zum Teil hitzige Diskussionen. Die Energiewende ist neben einem zunehmenden Energiemix auch der Übergang von der stoffgebundenen Energie, gebunden in der Kohle, gebunden in den Erdöl-Produkten, hin zu einer zunehmend regenerativ erzeugten elektrischen Energie. Selbst mit dem Ausbau der Netze für den elektrischen Strom in Richtung Kupferplatte BRD, hat die Vollelektrifizierung ein Umsetzungsproblem: es fehlen die wichtigen Energiespeicher. Das elektrische Netz kann nicht quasi wie ein Schwamm beliebig viel elektrische Energie aufnehmen, sondern immer nur so viel, wie zeitgleich an anderer Stelle elektrische Energie abgenommen wird. Darum müssen, mangels Energiespeicher, immer noch die Windenergieanlagen abgeregelt werden zur Vermeidung einer Überlast in den Netzen. Mit dem Abregeln der Windenergieanlagen geht bereits jetzt im Giga-Watt-Bereich grundsätzlich erzeugbare elektrische Energie unwiderruflich verloren. Batterien allein sind als Speicher in dieser Größenordnung keine Option mehr; Batterien und Wasserstoff ergänzen vielmehr einander.

The book introduces you to the numerous topics of the energy transition with exciting subject matter. At the same time, you will learn about what are probably the most exciting developments in the modern world with the challenges of today; on the one hand with a view to maintaining energy supply security for people, and on the other hand with a view to the many opportunities for future generations. The book explains why the energy transition has not yet become a reality and why the energy transition is now gaining momentum. A book about the energy transition also necessarily deals with structural change and is also a testimony to the huge efforts and challenges that the regions are making and overcoming when the goals are clearly defined and when the regional identity is supported by these goals on an inter-municipal basis. A book about the energy transition is also a testimony to the great efforts and challenges that companies in the energy markets are making and overcoming when established structures are broken up and networked with new or complementary business models, when complementary services are created with the expanded energy products. The success of the energy transition therefore depends crucially on the start and speed of implementation of defined goals, which requires determination and regional identity with the emerging fields of action.

Das Buch führt mit spannender Thematik an die zahlreichen Tangenten der Energiewende heran. Sie erfahren zugleich die wohl spannendsten Entwicklungen der modernen Welt mit den Herausforderungen von Heute; dies zum einen mit Blick auf den Erhalt der Energieversorgungssicherheit für die Menschen, dies zudem mit Blick auf die vielen Chancen für die kommenden Generationen. Das Buch erklärt, warum die Energiewende bisher nicht real werden konnte und wodurch die Energiewende jetzt Fahrt aufnimmt. Ein Buch über die Energiewende befasst sich unbedingt auch mit dem Strukturwandel und ist auch ein Zeugnis der sehr großen Anstrengungen und der Herausforderungen, welche die Regionen eingehen und bewältigen, wenn die Ziele klar definiert sind und wenn die regionale Identität mit diesen Zielen interkommunal unterstützt ist. Ein Buch über die Energiewende ist zudem auch ein Zeugnis großer Anstrengungen und Herausforderungen, welche die Unternehmen in den Energiemärkten eingehen und bewältigen, wenn die etablierten Strukturen aufgebrochen werden und vernetzt werden mit neuen bzw. mit ergänzenden Geschäftsmodellen, wenn mit den erweiterten Energieprodukten die ergänzenden Dienstleistungen entstehen. Der Erfolg der Energiewende hängt somit ganz entscheidend ab von dem Beginn und von dem Tempo der Umsetzung definierter Ziele, was die Entschlossenheit und die regionale Identität mit den entstehenden Handlungsfeldern erfordert.

Literature is to describe the waves of our thoughts and feelings with the help of words and sentences and create the same waves in others. This definition is the correct definition of literature. The works written in this way are called literary works. In order to properly understand the word literature, it is necessary to define the word art as well as fine arts...If the commodity (material) in fine arts is sound, then fine art is musical; if there are colors and lines, then there will be a picture; stone or other different materials will be sculptures; if there is stone, wood, brick, and other materials (soil, clay), it is architecture; body, muga (hands, eyebrows, eyes) movements are games (tans); speech, and words become literature...These six types of beautiful watches are divided into two groups with the attention of getting closer to each other. Literature, music, game (dance) - one category; painting, sculpture, architecture are one category.

Reclaiming Technology: A poetic-scientific vocabulary aims to evoke ways of thinking about, and intervening in, technology worlds through a series of blended writing styles.Consisting of thirty-five short essays, contributors were asked to problematize some aspect of their research with technology – broadly conceived as artifact, process, craft, infrastructure, or concept – without being constrained by the more traditional repertoires of academic publishing. The result is a set of critical and experimental texts whose vocabulary speaks to the poetic, affective, and mundane modes through which technology can inspire and make anew.The ambition to reclaim stems from a collective desire to shift the grounds upon which exuberant technological claims making occurs. The book’s poetic-scientific approach is an effort at rendering technology otherwise so as to enable the emergence of alternate claims-making pathways towards more just and dignified socio-technical futures.The book should appeal to those who are curious about the technology-society nexus in more general terms. More particular audiences include anthropology and STS scholars, students (at all levels) interested in methods and writing, and practitioners looking for conceptual resources to think about technology differently.

Preface City of Mosul is one of the important Iraqi cities that has been distinguished from other Iraqi cities with civilized features that affected the character of its social life, throughout its long social history, which gave the city a unique cultural depth. It seems that the Islamic conquest of the city of Mosul in 16 AH was a shining station in the history and character of the city, when Islamic religion entered it with Arab tribes who migrated from the Arabian Peninsula. The city acquired a new and bright civilized reputation depending on the new Islamic culture with its values, principles, morals and ideals. Thus, the province of Mosul remained throughout the Umayyad and Abbasid eras ruled by Muslim rulers and princes. Many states were established in Mosul during that period, including the Hamdaniyah, Aqiliyah, Atabegiyah and other emirates and countries. After the fall of the Abbasid Caliphate in 656 AH / 1258 AD by the Tatar Mongol invasion, city of Mosul was governed by the Mongol ruler in 1260 AD. The city, like other Iraqi cities, suffered from oppression, persecution, killing and destruction, which prompted many of its people to leave out of it.

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.

A celebrated international bestseller that exposes the ticking time-bomb underneath our new technological order.The resources race is on. Powering our digital lives and green technologies are some of the Earth's most precious metals - but they are running out. And what will happen when they do? The green-tech revolution will reduce our reliance on nuclear power, coal, and oil, but by breaking free of fossil fuels, we are setting ourselves up for a new dependence - on rare metals like cobalt, gold, and palladium. These are essential to electric vehicles, wind turbines, and solar panels, as well as our smartphones, computers, tablets, and other technologies. But we know very little about how rare metals are mined and traded, or their environmental, economic, and geopolitical costs - until now.

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.

Today, deep underground basements are an important component of new urban building construction. This is often because parking in most large cities is generally inadequate and often serviced by aging, outdated, and deteriorated above-grade parking structures that do not fit the surrounding architecture and occupy valuable aboveground space. The integration of underground parking into major, new building projects in urban environments can enhance the aesthetic and economic values of the overall development. The current state-of-practice for seismic design of buildings with multiple underground storeys involves approximate approaches that primarily differ according to the designer¿s judgement and experience. While current research mainly aims at understanding the effect of soil structure interactions, this study has ultimate goal of finding appropriate recommendations concerning the inclusion of underground storeys in the modelling and analysis of reinforced concrete buildings and optimizing their design.

The aquatic systems are extremely important to mankind as they have various uses, including drinking water supply, irrigation, navigation, recreation, etc. These are also source of organic productivity. Water is one of the essential items needed by man, plant, animal and other living beings for their survival. Water is most precious resources on the earth covering almost 70% of the earth's surface. There are several books and research dealing with water and water related concepts, and maximum number of books and research are focused on marine water or river water. We all know that in hilly region, one of the most important sources of fresh water is ¿lakes¿. And these lakes are the main source of water in most of the river in Himalaya Region. As per their geography, location, climatic condition and approach of reach, these lakes are highly tough. Due to this fact, they are so far from any kind of pollution, and serves the mankind by fulfilling their basic need of life ¿ drinking water.

Voltage sags and harmonics disturb the power quality and this can be overcome by custom power device called Dynamic Voltage Restorer (DVR). The DVR is normally connected between the source or feeder and critical or sensitive load. The performance of DVR depends on the efficiency of the control technique involved in reference signal generation considering phase angle jumps. The control technique shall compensate the voltage disturbances and shall reject the load current disturbance. If voltage regulation is high, disturbance rejection ability decrease and vice versa Hence a robust and optimal control technique is very much required to compromise between voltage regulation and disturbance rejection. The work is focuses on implementation of various control techniques with suitable voltage source converter topology for proper voltage regulation and disturbance rejection.

Nutmeg is an important tree spice which produces two different spices namely Nutmeg and mace. The Nutmeg fruits are harvested on time at the proper stage of maturity in order to maintain their nutrient level as well as attaining desirable quality. Presently, the method adapted for harvesting Nutmeg in Konkan region by anual i.e. by hand picking, by shaking the tree branches or by using bamboo stick having a curves hook. It was therefore necessary to develop harvesting system with simple design, easy for operation, low cost but higher working efficiency.
