Students’ Precedence of Attributes Related Online Management Education – A RIDIT Approach

This paper sheds light in understanding the effectiveness of online management education by ranking the priority, perception and preference shown by students while they are considering online management education. The students’ precedence of attributes which are in favor and also against the online management education was considered.The ranking of student’s preference and priority of attributes related to online management education was measured and analyzed by RIDIT approach and was inferred that major advantages of online management education includes convenience in performing group assignments, assessments and group projects. Respondents also felt that the quality of courses and pedagogy in online management courses is superior and the Collaborative and interactive learning and teaching were also considered a benefit of performing online management education.  However the major limitations related to online management education were found to be No proper accreditation and certification, No recognition by university or education board and also the credibility of exams, assessments and evaluation system was also skeptical. This paper helps in understanding the areas in which the online management education can enhance its favorable features and thereby overcoming its restrictions and increasing the quality of course delivery by using an innovative digital platform.

Fabrication of Horizontal Silicon Nanowires Using a Thin Aluminum Film as a Catalyst

Silicon nanowires have been the topic of research in recent years for their significant attention from the electronics industry to grow even smaller electronic devices. The semiconductor industry is built on silicon. Silicon nanowires can be the building blocks for future nanoelectronic devices. Various techniques have also been reported in fabricating the silicon nanowires. But most of the techniques reported, grow vertical silicon nanowires. In the semiconductor industry, integrated circuits are designed and fabricated in a horizontal architecture i.e. the device layout is flat compared to the substrate. When vertical silicon nanowires are introduced in the semiconductor industry, a whole new architecture is needed to fabricate an electronic device. If the silicon nanowires can be grown horizontally, it will be much easier to incorporate these nanowires in the current architecture. In this thesis, horizontal silicon nanowires were grown on top of a silicon substrate in a bottom up approach. A thin layer of pure aluminum was used as a catalyst to grow the silicon nanowires. In this process, silicon from the substrate itself acts as a source to grow the nanowires. A device cannot be fabricated if the silicon nanowires are in full contact with the underlying silicon substrate. Therefore, in the later part, these silicon nanowires were grown on top of an oxide layer using the same conditions. Several windows were etched in the oxide layer with variable oxide widths to observe the growth of these nanowires

Life history and production studies of Sialis californica Banks and Sialis rotunda Banks (Megaloptera : Sialidae)

Comparative ecological studies of Sialis californica Banks and Sialis rotunda Banks were made in Western Oregon from 1966 to 1968. Field collections for S. rotunda were made in fish holding pond at the Oak Creek laboratories, 5 miles west of Corvallis, Benton County, and for S. californica in enriched sections of Berry Creek experimental stream, 13 miles north of Corvallis. Life histories were determined in aquaria, in laboratory streams and the natural habitats. S. rotunda, predominantly a pond species, completed its life cycle in one year in all situations. S. californica, commonly a stream species, took one or two years depending on oviposition time and food availability. Both species were reared successfully in the laboratory through all stages of their life cycle. There are ten larval instars. The larvae are carnivorous and feed on insects and other small benthic organisms. Biweekly or monthly samples were collected from the two locations for density, biomass, growth rate and production studies. Density and biomass of S. rotunda in the pond were much higher than for S. californica in the stream. Enrichment with sucrose and urea resulted in differences in density and biomass of S. californica between the four experimental sections at Berry Creek. The unenriched section usually had a high density but low or similar biomass compared with the enriched sections which had few individuals. The lower density in the enriched sections was associated with unfavorable substrate conditions for early-instar larvae because of dense mats of the filamentous bacterium, Sphaerotilus natans. Larger larvae were not hindered by the S. natans filaments and had rapid growth because food was abundant. Production of both species was calculated by two methods: (1) Ricker's (1946) method, the product of growth rate and mean biomass; and (2) Allen's (1951) graphical method, using numbers per m² and mean individual weight at each sampling date, The results from both methods were comparable, with the graphical method usually providing a slightly higher estimate of production. Annual production of S. rotunda in the pond was 13.18 Kilocalories/ m². This was more than double the production of S. californica in any of the sections of Berry Creek. In Berry Creek, the population in the unenriched section had low growth rate but the density of larvae resulted in high biomass and a comparable production to that in the enriched sections. The accumulated annual production was: unenriched, 4.94 Kilocalories; enriched, 6, 34 Kilocalories. The relationship between larval growth and food consumption rate was established by experiments in laboratory streams during summer and winter. These data were used to estimate food consumption by field populations. In the pond, S. rotunda larvae consumed 137 gms/m²/year. In Berry Creek, individuals in enriched sections consumed one and half to two times more food than did individuals in the unenriched section

A DUPLICATE ACTIVE STORAGE INDEXES FOR MULTIPLE CLIENT ENVIRONMENTS

As opposed to the present authenticated structures, for example skip list and Merkle tree, we design a singular authenticated structure known as Homomorphic Authenticated Tree, we present additional information about PoS and dynamic PoS. Whenever a verifier wants to determine the integrity of the file, it at random selects some block indexes from the file, and transmits these to the cloud server. To the very best of our understanding, no existing dynamic PoSs supports this method. We developed a novel tool known as HAT which is an excellent authenticated structure. We suggested the excellent needs in multi-user cloud storage systems and introduced the type of deduplicatable dynamic PoS. Existing dynamic PoSs can't be extended towards the multi-user atmosphere. Because of the problem of structure diversity and tag generation, existing system can't be extended to dynamic PoS. An operating multi-user cloud storage system needs the secure client-side mix-user deduplication technique, which enables a person to skip the uploading process and acquire the possession from the files immediately, when other proprietors of the identical files have submitted these to the cloud server. to lessen the communication cost both in the evidence of storage phase and also the deduplication phase concentrating on the same computation cost. We prove the safety in our construction, and also the theoretical analysis and experimental results reveal that our construction is efficient used. Within this paper, we introduce the idea of deduplicatable dynamic evidence of storage and propose a competent construction known as DeyPoS, to attain dynamic PoS and secure mix-user deduplication, concurrently

Ionic polarization-induced current-voltage hysteresis in ch3nh3pbx3 perovskite solar cells

CH3NH3PbX3 (MAPbX3) perovskites have attracted considerable attention as absorber materials for solar light harvesting, reaching solar to power conversion efficiencies above 20%. In spite of the rapid evolution of the efficiencies, the understanding of basic properties of these semiconductors is still ongoing. One phenomenon with so far unclear origin is the so-called hysteresis in the current–voltage characteristics of these solar cells. Here we investigate the origin of this phenomenon with a combined experimental and computational approach. Experimentally the activation energy for the hysteretic process is determined and compared with the computational results. First-principles simulations show that the timescale for MAþ rotation excludes a MA-related ferroelectric effect as possible origin for the observed hysteresis. On the other hand, the computationally determined activation energies for halide ion (vacancy) migration are in excellent agreement with the experimentally determined values, suggesting that the migration of this species causes the observed hysteretic behaviour of these solar cells

Effect of Energy Input on Microstructure and Mechanical Properties of Titanium Aluminide Alloy Fabricated by the Additive Manufacturing Process of Electron Beam Melting.

Titanium aluminides qualify adequately for advanced aero-engine applications in place of conventional nickel based superalloys. The combination of high temperature properties and lower density gives an edge to the titanium aluminide alloys. Nevertheless, challenges remain on how to process these essentially intermetallic alloys in to an actual product. Electron Beam Melting (EBM), an Additive Manufacturing Method, can build complex shaped solid parts from a given feedstock powder, thus overcoming the shortcomings of the conventional processing techniques such as machining and forging. The amount of energy supplied by the electron beam has considerable influence on the final build quality in the EBM process. Energy input is decided by the beam voltage, beam scan speed, beam current, and track offset distance. In the current work, beam current and track offset were varied to reflect three levels of energy input. Microstructural and mechanical properties were evaluated for these samples. The microstructure gradually coarsened from top to bottom along the build direction. Whereas higher energy favored lath microstructure, lower energy tended toward equiaxed grains. Computed tomography analysis revealed a greater amount of porosity in low energy samples. In addition, the lack of bonding defects led to premature failure in the tension test of low energy samples. Increase in energy to a medium level largely cancelled out the porosity, thereby increasing the strength. However, this trend did not continue with the high energy samples. Electron microscopy and X-ray diffraction investigations were carried out to understand this non-linear behavior of the strength in the three samples. Overall, the results of this work suggest that the input energy should be considered primarily whenever any new alloy system has to be processed through the EBM route
