Das Hauptziel dieser Forschungsarbeit ist es, die verschiedenen Ziele anzugehen, wie z.B. (i) die Nutzung des Wechselstrommodells und die Entwicklung neuer Zielfunktionen, (ii) die ausschlie liche Verwendung von Stromphasen anstelle von Spannungsphasen, die von den meisten bestehenden Forschern verwendet werden, (iii) die Bew ltigung von PMU-Ausfallproblemen, (iv) die Einbeziehung fehlerhafter PMU und Messunsicherheit in die mathematischen Modelle, (v) die Erkennung von parallelen Leitungsausf llen und (vi) die Sicherstellung der Kosteneffizienz der entwickelten Modelle. Diese gesamte Forschungsarbeit wird phasenweise durchgef hrt, um die oben genannten Ziele zu erreichen. Erstens werden die Spannungsphasen zur Entwicklung des TLOD-Modells verwendet. Zweitens werden die Stromphasoren zur L sung des Problems der Erkennung von Leitungsausf llen (TLOD) herangezogen. Auch die Erkennung von parallelen Leitungsausf llen wird zum ersten Mal mit stromphasorbasierten Algorithmen validiert. Die Wirksamkeit und Durchf hrbarkeit der vorgeschlagenen TLOD-Algorithmen wurde an verschiedenen IEEE-Benchmark-Testsystemen in der MATLAB-Umgebung berpr ft. Die Leistung der vorgeschlagenen TLOD-Modelle wurde durch Berechnung der Erkennungsgenauigkeit (DA) bewertet.

Sericulture is a rearing of silkworm for the production of raw silk. The natural silk is obtained from four species of silkworm viz. Mulberry silkworm (Bombyx mori), Tassar silkworm (Antheracea mylitta.), Muga silkworm (Antheracea assamensis) and Eri silkworm (Philosemia ricini). The mulberry silk is one of the superior over other silk.The quality and quantity of mulberry silk is greatly varied with respect of different condition to which the plan is exposed. The component of leaf varies according to variety of mulberry and high yielding bivoltine silkworm hybrids. It is advisable to choose silkworm strain and mulberry variety which is suitable for particular region. India has strong sericultural base with enormous potential for boosting silk production. In India's context, stability of double cross hybrid with higher survival is more relevant than higher productivity under prevailing situation. The stability of bivoltine crop was not achieved mainly due to climate, rearing and socio-economic conditions. This necessitated evolution of the double cross hybrid silkworm breeds for increased cocoon and gradable raw silk production.

The primary aim of this research work is to address the different objectives such as (i) exploitation of the AC model and development of the new objective functions, (ii) utilization of current phasors exclusively instead of voltage phasors which are used by most of the existing researchers, (iii) tackling of PMU outage issues, (iv) incorporation of faulty PMU and measurement uncertainty into the mathematical models, (v) detection of parallel line outage and (vi) ensuring the cost-effectiveness of the developed models. This entire research work is accomplished phase-wise to achieve the objectives mentioned above. Firstly, the voltage phasors are used to develop the TLOD model. Secondly, the current phasors are utilized to solve the transmission line outage detection (TLOD) problem. The detection of parallel line outage is also validated for the first time using current phasor based algorithms. The effectiveness and viability of the proposed TLOD algorithms have been checked on different IEEE benchmark test systems in the MATLAB environment. The performance of the proposed TLOD models has been evaluated by computing the detection accuracy (DA).

Computer-aided implant surgery has been introduced in recent years, with the aim of simplifying and improving the diagnostic phase and providing predictable implantology results, as this field is a highly operator-dependent surgical technique. It can also reduce the need for bone regeneration, allowing the use of all available bone tissues and respecting prosthetic-guided implantology principles, achieving a final result that satisfies both aesthetics and biomechanics. Computer aided implantology is useful and beneficial to the patients as they experience less surgical trauma, pain, and swelling while their recovery time is reduced and the ability to return to their normal lives is expedited.

Automotive industry is continuously working for the development of the vehicles. New innovative features and advance methods of power generation are being innovated so that the industry can minimize the use of fossil fuels such as petrol and diesel to save them for future. Global warming has also become a major problem for the world and to control the temperature increase, we have to control the emission of vehicle exhaust. The electric vehicles are the best alternative for this and to solve the problem of more consumption of electric power, the vehicles with the installed solar panels can be the best option because we know that sun is the best renewable energy source which is going to last till the existence of human life. This report concludes the designing parameters required for the designing of the vehicle according to the need of future utilization and which can be merged with the solar and electric power source. The objective of the report is to design a vehicle which consist the features like light weight, good ergonomics, compatible with electric system on safety parameters, and good aesthetics.

This book presents the research works and investigations related to the contingency due to line outage. Firstly, the detail assessment of the impact of line outage has been studied through PV curve method. Later on, investigation has been carried out to find the most critical line in normal loading condition. In view of this, ranking of the line outage contingencies are done on the basis of proposed overall severity index (OSI) comprising of two index i.e. active power deviation-based index and voltage deviation based index. Furthermore, the critical contingency is identified though well-known L-index. Moreover, the impact of critical contingency is analysed through new indices namely voltage deviation index (VDI) and loss deviation index (LDI). The effectiveness and viability of the proposed schemes are checked on different IEEE benchmark systems in MATLAB environment.

This book presents the research works related to the development of new algorithms for line outage identification using voltage phasor of PMU. Three new voltage phasor-based algorithms are introduced. The proposed three models are 1) Direct comparison of phasor angle measurement (DCPAM) model 2) Comparison of bus current injection (CBCI) model 3) Comparison of bus power injection mismatch (CBPIM) model. The proposed algorithms also consider the constraints like PMU outage issue and measurement noises which reflect the novelty and reliability of the methodology. The performance of the proposed methodologies are checked on different IEEE test systems in terms of accuracy.

Die computergest tzte Implantatchirurgie wurde in den letzten Jahren mit dem Ziel eingef hrt, die Diagnosephase zu vereinfachen und zu verbessern und vorhersagbare implantologische Ergebnisse zu erzielen, da dieser Bereich eine stark vom Operateur abh ngige chirurgische Technik ist. Sie kann auch die Notwendigkeit der Knochenregeneration verringern, indem sie die Nutzung aller verf gbaren Knochengewebe erm glicht und die Prinzipien der prothetisch gef hrten Implantologie respektiert, um ein Endergebnis zu erzielen, das sowohl sthetisch als auch biomechanisch zufriedenstellend ist.Die computergest tzte Implantologie ist n tzlich und vorteilhaft f r die Patienten, da sie weniger chirurgische Traumata, Schmerzen und Schwellungen erleiden, w hrend sich ihre Genesungszeit verk rzt und sie schneller in ihr normales Leben zur ckkehren k nnen.
