ENERGY DEMAND AND EXHAUST GAS EMISSIONS OF MARINE ENGINES : MITIGATING TECHNOLOGIES AND PREDICTION | Author : V.THANIKACHALAM | Abstract | Full Text | Abstract :In recent years more and more focus has been placed on the environmental aspects of ships, because
of the great attention to exhaust gas emissions from ships including CO2, a leading contributor to
Green House Gasses (GHG) emissions, due to their negative effect on global warming.
Maritime transport has clear environmental advantages: it expends relatively little energy and its
infrastructure requirements are small compared to land-based transport modes. Due to low energy
need, shipping is a highly carbon-efficient transport mode, i.e. carbon dioxide emissions are low
compared to the weight of cargo transported. Shipping can be up to four times more efficient than
road transport. Because of relatively small contribution to greenhouse gas emissions shipping is also
good in the terms of mitigation of climate change.
However, air pollution from ships has been unregulated until recently. Ships currently produce about
half as much sulphur oxides (SOx ) as land-based sources and about a third as much nitrogen oxides
(NOx ). Ships emit several hazardous air pollutants such as sulphur dioxide, nitrogen oxides and fine
particles. Once emitted, airborne emissions can travel considerable distances so the shipping
emissions affect land air quality. Also the emissions from ships during port stays can be substantial
contributor to the local air quality.
Thus,this report describes the different exhaust gas emission products, their untoward effects and the
various ways in which it can be mitigated |
| LEVERAGING TENSOR FLOW FOR SPEECH RECOGNITION AND IMAGE CLASSIFICATION LINKED TO CONVOLUTED NEURAL NETWORKS (CNN) FOR EFFICACIOUS DEEP LEARNING | Author : Hardik Chaudhary, Vipul Goyal | Abstract | Full Text | Abstract :Deep learning these days is playing a very major role in natural signal and information processing,like
speech recognition and image classification. Deep learning technologyis immersed on the basis of the
human brain. In deep learning, artificial neurons network automaticallytrained itself by large datasets that
discovers connected patterns without the help of a human.Deep learning detects a pattern in unstructured
data like image, sound, video, and text.For Image classification, CNN in deep learning is very popular. In
many patterns, CNN performs bettercompared to human in a large dataset like image. In our research, we
have used python with Kerasfor binary image classification. In this, we are using an animal’s dataset,
namely cat and dog, for image classification. Four different parameters with four different combinations
have been appliedin CNN for comparison. It is shown that for Binary image classification combination of
sigmoid classifier and Relu activation function gives higher classification accuracy than any other
combination of classifier and activation function |
