Guest Editorial Marine Systems Electrification
No full textShipboard Electrical Applications are increasing in marine systems, from generators to users (propulsion, thrusters, handling, air conditioning, auxiliaries, actuators, and so on), as a matter of fact. Electrical applications are largely utilized in many classes of “all electric” and “more electric” ships, such as cruise liners, naval vessels, supply vessels, yachts, offshore energy vessels, platforms, drilling rigs, cable/pipe-layers, ice-breakers, inland waterways, and so on. Beside the development of electrical applications, competition demands to reduce volume, weight, and emissions in order to cut ship capital expenditures and operating costs. A revision to the existing electric power system architectures is regarded as a promising way to meet such demands. In this view, power electronics is a key enabling technology along with advanced grid controls, energy storage systems, and by-wire-actuators to make electrical energy utilization more efficient and rational

Overview of Manufacturing PMC's Using Traditional and 3D printing Technology (FDM)
No full textAbstract: Composite materials are those materials which are made by combining two or more materials with unique properties. Polymer matrix composites are one of the most important composites which are used in various industries due to their light weight, high stiffness and high strength. Because of its advantages it is important to know the manufacturing techniques of PMCs. PMCs are used by automotive, pharmaceutical, sports and aerospace industries. This paper gives detailed review of different traditional and 3d printing methods of manufacturing Polymer Matrix Composites. These methods are more effective in making special shapes west bullet proofs, boat bodies and heavy cylinders. In recent research on effecting manufacturing of composite materials, it is found that the 3d printing technology makes some difference in making PMC with much better properties. In this review we also discuss about one of the 3d printing methods, that is Fusion Deposition Modeling for making PMCs with improved strength and properties.
Keywords: Stiffness, Strength, Polymer Matrix Composite, Manufacturing, FDM, 3d printing.

Modern Poetic Trends of Odisha versus the Neoteric Strives of Guruprasad
No full textThis paper tries to bring out the literary trends of Odia literature from nineteenth century to the last part of twentieth century. With reference to the long literary passage of some 175 years attempts have been made to introduce Guruprasad Mohanty and churn out the specialty by the by of his poetry. How the passage runs, with what level of frequency and with what newness all these things are discussed here in this article. What was the need of the modern literature and why it is so everything in this regard has been discussed along with various proofs. The real and underneath reasons of complexity of this post independence literature or the attitude and nature of this literature especially poetry are brought out here. Especially, here efforts have been taken to differentiate between the pre independence and post independence literature. Again, in one of the sections, there is a sketch of influences, inspirations and impacts of T.S. Eliot, his life, literature, philosophy, style and personal doctrines. Further, how he has influences Guruprasad Mohanty has also been discussed with ample examples. Overall an assessment has been made on the originality of Guruprasad's literature as well of the attempts of some other contemporary poets of this period.

A Selective Harmonic Elimination Method for Five-Level Converters for Distributed Generation
No full textIn distributed generation, high power capability and high efficiency are very important requirements. For this reason, this paper proposes a new analytical procedure for selective harmonic elimination in five-level inverters operating at fundamental frequency. For each modulation index, the proposed method calculates all possible switching angles eliminating a specified odd harmonic from the output voltage. The method has limited computational complexity, simple and cost-effective real-time implementation, and full capability of integration with closed loop control. Simulation and experimental results highlight full elimination of selected harmonic
Optimal Low Switching Frequency Pulsewidth Modulation of Current-Fed Three-Level Converter for Solar Power Integration
No full textLarge-scale photovoltaic energy conversion systems have been installed at many places across the world and they handle higher power levels. In high power conversion, low device switching frequency operation is preferred in order to satisfy the thermal constraints of semiconductor devices and also to improve efficiency. However, low device switching frequency operation leads to higher total harmonic distortion (THD) of the converter output currents. Synchronous optimal pulsewidth modulation (SOP) is an emerging low device switching frequency modulation technique, which has been successfully implemented for voltage source inverters without compromising on THD. The goal of our research is to propose, analyze, and implement a modified SOP technique for current source inverter topologies. The additional switching constraints for these inverter topologies have been included in the modified SOP technique. The experimental results obtained from a low-power prototype demonstrated its effectiveness
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
