Mechanical design and development aspects of a small AUV - Maya
(Institute for Systems and Robotics, 2007)
This paper contains a description of the mechanical design route that was adopted in building a small AUV (Autonomous Underwater Vehicle). At the outset, it is decided to follow a set of guidelines that defined a broad set ...
Pressure gauge experiments in India
(UNESCO, 2004)
Pressure measurements made in differing turbid water bodies and turbulent clear-water bodies have led to the inference that the effective mean-depth in situ density value, Row eff, of these water bodies is less than the ...
Field evaluation of navigational sensors using DGPS/GPS for a small AUV
(Allied, India, 2003)
This paper presents the preliminary results of a field experiment for low-cost strap down IMU/GPS combination for the estimation of 2-D components of vehicle position (Trajectory). In present approach the effects of earth ...
Performance of Honeywell silicon pressure transducers
(Allied, India, 2003)
Simultaneous calibration of three Honeywell pressure transducers (PPTR) at four ambient temperatures have been carried out using a novel static calibration system developed in-house. Calibration results indicated that ...
Endurance and stability of some surface meteorological sensors under land- and ship-based operating environments
(Allied, India, 2005)
The endurance and stability of some surface meteorological sensors under land- and ship-based operating environments is described. The sensors evaluated are those for measurement of relative humidity, barometric pressure ...
TNF-a and IL-6 inhibitory effects of cyclic dipeptides isolated from marine bacteria Streptomyces sp.
(Springer and Business Media, 2017)
Inflammation is mediated by a variety of soluble factors, including a group of secreted polypeptides known as cytokines. The anti-inflammatory cytokines are a series of immune regulatory molecules that control the pro ...
First record of cold-seep induced enhanced water column methane concentrations from the EEZ of India
(Springer, 2021)
A scientific expedition was carried out onboard RV Sindhu Sadhana (12th to 23rd February, 2020) for gas hydrate/cold-seep exploration in Mannar basin, northern Indian Ocean. We observed for the first time gas flares in the ...
Seismotectonics and 3-D seismic velocity structure of the Arunachal Himalaya
(Elsevier, 2023)
Knowledge of seimotectonics of Arunachal Himalaya holds the key to comprehend the complex deformation scenario in the eastern Himalayan syntaxial (EHS) zone comprising India, Eurasia and Burma plates. Data from a network ...
Eastern Arabian Sea CO2 outgassing during the last deglaciation and Holocene related to deep-water carbonate chemistry
(Elsevier, 2023)
Glacial to interglacial changes in atmospheric CO2 are an intriguing part of carbon reorganization in the climate system and are estimated by investigating deep-water carbonate ion concentrations ([CO32−]). The scarcity ...
Toxigenic Escherichia coli with high antibiotic resistance index recovered from sands of recreational beaches of Mumbai, India
(Elsevier, 2024)
Mumbai, India's seven-island city, is known for its sandy beaches as a major tourist attraction, but urbanization and industrialization have weakened the environment. Unregulated sewage disposal and untreated effluents off ...
