A packet loss compliant logic-based communication alogoritham for cooperative path following control
(International Federation of Automatic Control, 2013)We introduce an event driven communication logic for decentralized control of a network of robotic vehicles (agents). The strategy proposed is robust to packet losses and drives the vehicles to predefined paths while holding ... -
Observability analysis of 2D single-beacon navigation in the presence of constant currents for two classes of maneuvers
(International Federation of Automatic Control, 2013)We analyze the observability properties of an underwater vehicle (moving in 2D) performing single beacon navigation for two specic classes of maneuvers, whereby the vehicle measures its distance to a xed transponder located ... -
Four-quadrant propeller modeling: A low-order harmonic approximation
(International Federation of Automatic Control, 2013)We propose a four-quadrant propeller model suitable for energy-efficient motion planning of autonomous marine vehicles. The model can be used to capturethe main features of experimental thrust and torque curves by using a ... -
Evaluation of antioxidant activities in captive-bred cultured yellow seahorse, Hippocampus kuda (Bleeker, 1852).
(Elsevier, 2014)Globally, seahorses and other Syngnathid fishes are in great demand as they form an important ingredient in traditional Chinese medicine (TCM). As a consequence of dwindling supplies from natural sources, TCM traders are ... -
Fate of copper complexes in hydrothermally altered deep-sea sediments from the Central Indian Ocean Basin.
(Elsevier, 2014)The current study aims to understand the speciation and fate of Cu complexes in hydrothermally altered sediments from the Central Indian Ocean Basin and assess the probable impacts of deep-sea mining on speciation of Cu ... -
Dynamics of auto- and heterotrophic picoplankton and associated viruses in Lake Geneva.
(European Geosciences Union, 2014)Microbial dynamics have rarely been investigated in Lake Geneva, known as the largest lake in western Europe. From a 5-month survey, we report dynamic patterns of free-living virus, bacteria and small phytoplankton abundances ... -
Indian summer monsoon rainfall characteristics during contrasting monsoon years.
(Springer, 2014)The present paper presents a diagnostic study of two recent monsoon years, of which one is dry monsoon year (2009) and the other is wet monsoon year (2010). The study utilized the IMD gridded rainfall data set in addition ... -
Intramolecular Diels–Alder reaction as a key step in tandem or sequential processes: a versatile tool for the synthesis of fused and bridged bicyclic or polycyclic compounds.
(Elsevier, 2014)This review summarizes the recent examples of tandem or sequential reactions used for the last 10 years for the synthesis of fused and bridged bicyclic or polycyclic compounds with IMDA cycloaddition as the key means to ... -
Penicillin-mediated changes in viable benthic diatom assemblages – insights about the relevance of bacteria across spatial and seasonal scales.
(CSIRO Publishing, 2014)Penicillin, a beta-lactam antibiotic, cannot affect diatoms directly but does so through bacteria. Its effects on viable benthic diatom assemblages in a tropical environment were evaluated across spatial (intertidal sandflat, ... -
A revisit to vityaz transform fault area, Central Indian Ridge: Isotopic evidence of probable hydrothermal activity.
(OMICS Publishing Group, 2014)Boron and chlorine isotopes have been used as a proxy for tracing the presence of hydrothermal activity in the CIR area. Isotopic compositions of boron (delta<sup>11</sup>B) and chlorine (delta<sup>37</sup>Cl) measured ... -
Caerulomycin A- An antifungal compound isolated from marine actinomycetes.
(Scientific Research Publications, 2014)Actinomycetes have been prolific sources of novel secondary metabolites with a range of biological activities that may ultimately find application as therapeutic compounds. Hence several drug discovery companies are engaged ... -
Parameter optimization using GA in SVM to predict damage level of non-reshaped berm breakwater.
(Multi-Science Publishing Company, 2014)In the present study, Support Vector Machines (SVM) and hybrid of Genetic Algorithm (GA) with SVM models are developed to predict the damage level of non-reshaped berm breakwaters. Optimal kernel parameters of SVM are ... -
Observed intraseasonal and seasonal variability of the West India coastal current on the continental slope.
(Indian Academy of Sciences, 2014)We present current data from acoustic Doppler current profilers (ADCPs) moored on the continental slope off the west coast of India. The data were collected at four locations (roughly at Kanyakumari, Kollam, Goa, and Mumbai) ... -
Effect of water depth on the performance of intelligent computing models in predicting wave transmission of floating pipe breakwater.
(Multi-Science Publishing Company, 2014)Understanding the physics of complex system plays an important role in selection of data for training intelligent computing models. Based on the physics of the wave transmission of Horizontally Interlaced Multilayer Moored ... -
Modeling geochemical datasets for source apportionment: Comparison of least square regression and inversion approaches.
