Turkey's 2023 Energy Strategies and Investment Opportunities - Bok av Ceren Erdin & Gokhan Ozkaya - Häftad

Turkey's 2023 Energy Strategies and Investment Opportunities - Bok av Ceren Erdin & Gokhan Ozkaya - Häftad

In Turkey, current energy generations are not sufficient for the existing energy needs and besides, energy demand is expected to increase by 4¿6 per cent annually until 2023. Therefore, the government aims to increase the ratio of renewable energy resources (RES) in total installed capacity to 30 per cent by 2023. By this date, total energy investments are expected to be approximately $110 billion. Turkey is the fastest growing energy market among OECD countries. Therefore, Turkey is an attractive..

Synthesis of indolylquinoline and acridone alkalaids- A green approach - Bok av A Nepolraj & P Pitchai - Häftad

Synthesis of indolylquinoline and acridone alkalaids- A green approach - Bok av A Nepolraj & P Pitchai - Häftad

We have described the total syntheses of quinoline alkaloids, which include indoloquinoline, naphthyridine alkaloids like perlolidine and acridone alkaloids. Synthesis of 1-oxo-1,2,3,4-tetrahydrocarbazole was achieved with good yield using conventional and microwave procedure (unconventional energy). The utility of indole-3-butanoic acid and ethyl 4-(1H-indol-3-yl)butanoate were studied by adopting various catalysts and solvents. As our major synthetic targets were the indoloquinoline alkaloids,..

POWER QUALITY ENHANCEMENT - Bok av P. Bharath Kumar - Häftad

POWER QUALITY ENHANCEMENT - Bok av P. Bharath Kumar - Häftad

This book presents the nine switch converter based UPQC is simulated using MAT LAB/SIMULINK. It effectively reduces the current and voltage harmonics. The nine-switch converter is more suitable for replacing back- to-back converter in ¿series¿shunt¿ systems. As a further performance booster, a modified space vector modulation and 120 degree modulation scheme is presented for reducing the overall commutation count by 33%. It is also compensated for voltage sags, total harmonic distortion with proper..

Design & analysis of innovative solar deployment on dynamic buildings - Bok av Muhammad Rehan Siddiqi - Häftad

Design & analysis of innovative solar deployment on dynamic buildings - Bok av Muhammad Rehan Siddiqi - Häftad

Current buildings (in Europe) constitute roughly for 40% of the energy usage out of the total energy used. This level can be dropped to 10-20% if smarter and greener buildings are incorporated around the world. Buildings can be made smart by using dynamic movement (rotation), sensors and greener by deploying solar energy to conserve power. In this research, different innovative solar tracking techniques will be deployed on different structures (non-rotating and rotating). By means of simulation (LabVIEW)..

Unification of Gravitational and Electromagnetic Forces - Bok av Ling Jun Wang - Häftad

Unification of Gravitational and Electromagnetic Forces - Bok av Ling Jun Wang - Häftad

Professor Ling Jun Wang presents in this book first time ever a classical theory of unification of gravitational and electromagnetic forces, free of any of the fundamental problems of general relativity and particle physics. One of the important discoveries from this classical unification theory is the Wang¿s Law which states that the total linear momentum of the gravitational field transmitted into space is conserved. Wang's unification theory has naturally answered the historical action-at-distance..

Effect of feeding Moringa to Oreochlomis Shiranus in semi-intensive systems - Bok av Brian Tonthozo Ntakati - Häftad

Effect of feeding Moringa to Oreochlomis Shiranus in semi-intensive systems - Bok av Brian Tonthozo Ntakati - Häftad

Aqua-feed production is currently one of the fastest expanding agricultural industries of the world with annual growth rates in excess of 30% per year. Feed is very important in cultured fish in captivity as nothing is more important than sound nutrition and adequate feeding (FAO, 2014). This is further stressed by the fact that feed represents about 40 - 60% of total production cost in aquaculture (Fagbenro and Davies, 2003). Management, environmental factors and fish size all have an effect on..

OPTIMAL DG PLACEMENT FOR VOLTAGE IMPROVEMENT USING PSO - Bok av Besta Hariprasad - Häftad

The size and location of DG are the crucial factors in the application of DG for loss minimization. This book presents an algorithm for the identification of bus location using Sensitivity analysis and also an algorithm for the determination of size of the DG using PSO. This methodology is tested on IEEE 15 bus system. By installing DGs at all the potential locations with the determined sizes, the total real power loss of the system has been reduced by 83% and the voltage profile of the system is..
