Zooplankton abundance in Amini and Kadmat islands of Lakshadweep
No full textStudies on zooplankters collected from the lagoons of Amini and Kadmat islands of Lakshadweep Archipelago were carried out based on a survey conducted during January - February, 2014. The displacement volume ofzooplankton in Amini and Kadmat were 58.35 and 15ml per 100 m3 respectively. The density was also higher in Amini than in Kadmat which is estimated as 64480 and 47726 numbers per 100 m3 respectively. A total of twentyone groups of zooplankters viz., copepods,ostracods, chaetognaths, Lucifer sp., medusae, doliolids,mysids, tintinnids, euphausiids, appendicularians,siphonophores, cladocera, amphipods, isopods,polychaete larvae, prawn larvae, crab larvae, squilla larvae, molluscan larvae, fish eggs and fish larvae were recorded from these two ecosystems. Groupwise studies indicated the dominance of copepods in Amini forming 40% while in Kadmat, the maximum was contributed by crab larvae (50%). The dominance of crab larvae in Kadmat was due to a swarm of zoea stage of crab at station 2 in the western side of the island.Among the copepods, calanoid copepods contributed the maximum with 71% in Amini and 81% in Kadmat.Followed by the dominance of copepods in Amini,ostracods (33%) and crab larvae (14%) formed major components. In Kadmat, copepods formed the second dominant group which contributed 20% followed by prawn larvae (11%), ostracods (6%) and the share by other groups were less than 5%. Comparative studies on the occurrence of different groups of zooplankters in these two island ecosystems showed that copepods and ostracods were very much higher in Amini than in Kadmat while, crab larvae contributed more in Kadmat which was due to the swarming of zoea stage of crab. Both qualitative and quantitative abundance of zooplankters in these two ecosystems are presentedand discussed

Analytical modeling of ultrasonic surface burnishing process: Evaluation of residual stress field distribution and strip deflection
No full textUltrasonic surface burnishing (USB) process is a promising surface enhancement technique that improves fatigue life of components by exerting work hardening and compressive residual stress of the surface layers. However, USB is a complex process in practice, and there is not an analytical model published to facilitate the design and comprehension of the process. In the present paper an analytical elastic-plastic model was developed to correlate USB process factors to residual stress field (RSF). Also, deformation of strip samples was determined in the analytical approach. Parameters such static force, ultrasonic vibration amplitude, ball material and its diameter as well as ultrasonic vibration frequency were included in the model to find how they influence the residual stress variation and strip deflection. Two types of material constitutive equation i.e. Johnson-Cook (JC) that is sensitive to strain rate as well as Chaboche hardening that is influenced by cyclic loading were considered to find which material behavior is more consistent with experimental results. The experiments have been carried out on two different materials with various initial state of residual stress field (IRSF). It was obtained from the results that residual stress field variation and strip deflection obtained by experiments are consistent well with the values derived from analytical model. Therefore, the model was comprehensively used to find how the USB process factors influence the RSF and strip deflection
Field relations, geochemistry and geodynamic implications of chromitites from the Bandan Mine, Eastern Iran
No full textThe Bandan chromite mine is the main chromite deposit in Sistan suture zone, eastern Iran. The chromite deposits are structurally tabular to lens-shaped bodies hosted by dunitic to harzburgitic mantle peridotites. Similar to Alpine type podiform chromites, chromitite pods are enclosed within dunitic envelops. The chromites show mainly massive to disseminated and also brecciated textures. Chemically, the Cr/Fe ratio is higher than 2 and TiO2 content in accordance with ophiolitic chromites is low (< 0.2 wt. %). As a result of low Cr# (Cr# = Cr x 100 / (Cr + Al)) ranging from 50 to 52 the Bandan chromite deposit is high-Al type. Calculated parental melt chemistry shows MORB (Mid-ocean ridge basalt)-type signature with Al2O3 and FeO/MgO ratio contents of 15-16 and 1.1-1.2, respectively. Although the geodynamic setting of high-Al podiform chromites have been debated but petrographical - geochemical characteristics of ophiolitic mantle-crust sequences may relate chromite genesis to supra-subduction zone setting
A compiler for multi-key homomorphic signatures for Turing machines
No full textAt SCN 2018, Fiore and Pagnin proposed a generic compiler (called “Matrioska”) allowing to transform sufficiently expressive single-key homomorphic signatures (SKHSs) into multi-key homomorphic signatures (MKHSs) under falsifiable assumptions in the standard model. Matrioska is designed for homomorphic signatures that support programs represented as circuits. The MKHS schemes obtained through Matrioska support the evaluation and verification of arbitrary circuits over data signed from multiple users, but they require the underlying SKHS scheme to work with circuits whose size is exponential in the number of users, and thus can only support a constant number of users. In this work, we propose a new generic compiler to convert an SKHS scheme into an MKHS scheme. Our compiler is a generalization of Matrioska for homomorphic signatures that support programs in any model of computation. When instantiated with SKHS for circuits, we recover the Matrioska compiler of Fiore and Pagnin. As an additional contribution, we show how to instantiate our generic compiler in the Turing Machines (TM) model and argue that this instantiation allows to overcome some limitations of Matrioska: • First, the MKHS we obtain require the underlying SKHS to support TMs whose size depends only linearly in the number of users. • Second, when instantiated with an SKHS with succinctness poly(λ) and fast enough verification time, e.g., S⋅logT+n⋅poly(λ) or T+n⋅poly(λ) (where T, S, and n are the running time, description size, and input length of the program to verify, respectively), our compiler yields an MKHS in which the time complexity of both the prover and the verifier remains poly(λ) even if executed on programs with inputs from poly(λ) users. While we leave constructing an SKHS with these efficiency properties as an open problem, we make one step towards this goal by proposing an SKHS scheme with verification time poly(λ)⋅T under falsifiable assumptions in the standard model
First data on the taxonomic diversity of the Portulaca oleracea aggregate (Portulacaceae) in Iran
No full textThe review of specimens from Iran belonging to the Portulaca oleracea L. aggregate resulted in the recognition of six microspecies: P. cypria Danin, P. granulatostellulata (Poelln.) Ricceri & Arrigoni, P. nitida (Danin & H.G.Baker) Ricceri & Arrigoni, P. rausii Danin, P. socotrana Domina & Raimondo, and P. trituberculata Danin, Domina & Raimondo, all reported for the first time for the flora of Iran. The identification was based on the microscopic study of seeds. It is noted that P. oleracea is not confirmed for Iran. Distribution data and an identification key for Portulaca microspecies in Iran are presented
Decomposing changes in the conditional variance of GDP over time
No full textA well established fact in the growth empirics literature is the increasing (unconditional) variation in output per capita across countries. We propose a nonparametric decomposition of the conditional variation of output per capita across countries to capture different channels over which the variation might be increasing. We find that OECD countries have experienced diminishing conditional variation while other regions have experienced increasing conditional variation. Our decomposition suggests that most of these changes in the conditional variance of output are due to unobserved factors not accounted for by the traditional growth determinants. In addition to this we show that these factors played very different roles over time and across regions.A well established fact in the growth empirics literature is the increasing (unconditional) variation in output per capita across countries.

A two-stage strategy for generator rotor angle stability prediction using the adaptive neuro-fuzzy inference system
No full textGenerator rotor angle oscillations can be caused by sudden changes in its mechanical power input or its electrical power output. When dampening or synchronizing torque is inadequate, rotor angle instability occurs, resulting in an increase in rotor angle, loss of synchronism, or oscillatory swings of the rotor angle with increasing amplitude. To this end, in this work, we offer a novel two-stage approach for predicting rotor angle stability following a large disturbance. The process begins with the creation of a database of dynamic simulation scenarios. This collection contains a wide set of stable and unstable rotor angle trajectories derived from different fault simulations. Then, the fuzzy c-means (FCM) clustering algorithm is utilized to put the sampled data of rotor angles with the highest degree of similarity in the same cluster. Angle sets generated by FCM are used to train the adaptive neuro-fuzzy inference system (ANFIS). Finally, the trained ANFIS is used to predict the future rotor angle stability situation of generators. In addition, a stability index is suggested in this article, which will assist ANFIS in more accurately predicting the stability condition. The efficiency of the proposed method is tested on the IEEE 39-bus system. The obtained results from simulations confirm that the proposed strategy can correctly predict the rotor angle instability or stability situation of generators in a few cycles after fault clearance
Integration of chemical looping combustion for cost-effective CO2 capture from state-of-the-art natural gas combined cycles
No full textChemical looping combustion (CLC) is a promising method for power production with integrated CO2 capture with almost no direct energy penalty. When integrated into a natural gas combined cycle (NGCC) plant, however, CLC imposes a large indirect energy penalty because the maximum achievable reactor temperature is far below the firing temperature of state-of-the-art gas turbines. This study presents a techno-economic assessment of a CLC plant that circumvents this limitation via an added combustor after the CLC reactors. Without the added combustor, the energy penalty amounts to 11.4%-points, causing a high CO2 avoidance cost of 93.8/ton) with an energy penalty of 8.1%-points. This conventional CLC plant would also require a custom gas turbine. With an added combustor fired by natural gas, a standard gas turbine can be deployed, and CO2 avoidance costs are reduced to 96.3/ton when a hydrogen cost of 90.3/ton by lowering the energy penalty to only 0.6%-points. An attractive alternative is, therefore, to construct the plant for added firing with natural gas and retrofit the added combustor for hydrogen firing when CO2 prices reach very high levels
