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. |

Abstract | Full Text |
Abstract :Competition in an increasingly global and marketing has created new techniques of Maintenance in order to
upkeep their performance in terms of quality, productivity and cost. One such recent technique is condition
monitoring. Condition monitoring is nothing but checking the condition of the machine by using parameters
like vibration. The detection of incipient faults in machinery is very important in achieving unhindered
production in any plant. Condition monitoring if properly used can indentify most if not all of the factors
limiting the effectiveness and efficiency of the total plant. One of the most promising techniques of condition
monitoring is based on the analysis of vibration signals. In this work vibration is selected as the parameter
to assess the health of Dump Mill of a Banbury machine in a tyre manufacturing industry. In most of the
cases bearing points were selected to assess the vibration level. The normal level was fixed from the
Manuals, Manufacturers Catalogues and some Standards of Vibration. The vibration data were taken from
the machines with the help of Rio-Vibro Meter in different location and analysis carried out in order to find
the defective components in the machine and the corrective actions were also proposed at the end. |

ENSURING DISTRIBUTED ACCOUNTABILITY FOR DATA SHARING IN THE CLOUD |

Abstract | Full Text |
Abstract :Cloud computing enables highly scalable services to be easily consumed over the Internet on an
as-needed basis. A major feature of the cloud services is that users’ data are usually processed remotely
in unknown machines that users do not own or operate. While enjoying the convenience brought by this
new emerging technology, users’ fears of losing control of their own data (particularly, financial and
health data) can become a significant barrier to the wide adoption of cloud services. To address this
problem, in this paper, we propose a novel highly decentralized information accountability framework to
keep track of the actual usage of the users’ data in the cloud. In particular, we propose an objectcentered approach that enables enclosing our logging mechanism together with users’ data and policies.
We leverage the JAR programmable capabilities to both create a dynamic and traveling object, and to
ensure that any access to users’ data will trigger authentication and automated logging local to the JARs. |

COST OPTIMIZATION OF HEATING VENTILATION AIR CONDITIONING SYTEM (HVAC) BY USING BULIDING MANAGEMENT SYSTEM |
Author : Sandesh Hegde, Dr. Ramachandra C G |
Abstract | Full Text |
Abstract :Heating, ventilation and air conditioning (HVAC) will account major portion of the money
spent by any organization on the energy. The small adjustments in the HVAC systems will
improve the building internal environment and can save energy utilized by the HVAC system,
hence we can save money. Improvement of the energy efficiency will benefit in profitability of
the organization. HVAC System is more frequently applied in industrial facilities as well as in
living compounds and offices. Fully automatic control of these systems is impossible to avoid
while going to save the energy cost. Basic parameter of air that needs to be monitored and
regulated is temperature. The inside air temperature depends on the outside air temperature,
mechanical Infrastructure and occupancy in the zone. For this reason it is necessary to
produce a control technique capable of monitoring and controlling the temperature. By using
the signals given by the sensing elements such as sensors, control system will perform full
automatic control of HVAC system by comparing the current temperature with temperature
defined in the Building Management system hence regulate the flow of chilled air into the zone
by adjusting the Variable air volume throttle which acts as a gate to the chilled air into the
specified zone. Hence we can maintain desired comfort level inside the building.
The zone control will allows user to maintain different temperature in different zone. Hence
can save chilled water flow into the building, which will result in less load on chiller. Hence we
can some amount of energy which consumed by the chiller, so we can reduce the cost which is
spent on the energy. |

EMPLOYABILITY OF MACHINE LEARNING TECHNIQUES IN DEVELOPING ADVANCE TRAFFIC INFORMATION SYSTEM TO PREDICT HEAVY TRAFFIC CONGESTION IN MITIGATING CRASH OCCURRENCES DURING PEAK HOURS ON EXPRESS WAYS USING SUPPORT VECTOR MACHINE CLASSIFICATION |
Author : Jaskaran Singh Kohli |
Abstract | Full Text |
Abstract :The traffic security on roads is critical for the proficient activity of the regional framework, and there is
an intimate connection between traffic states and crashes on freeways, and the event of accidents might
be affected by the cooperation of various blends of traffic states upstream and downstream of the
accident area. In light of the accident information and the comparing traffic stream finder information
gathered on freeways in Shanghai, this investigation proposes a half and half model joining a support
vector machine (SVM) display with a k-means bunching calculation to foresee the probability of
accidents. The Random Forest (RF) display is utilized to choose the critical and noteworthy factors for
model development from the information of the traffic stream 5– 10 min before the accident happened. At
that point, the cross-approval and transferability of various models (SVM demonstrate without variable
choice, SVM display with variable determination, and a half and half SVM show with variable choice)
are resolved to utilize 577 accidents and 5794 coordinated non-crash occasions. The results show that
the mishap figure show close by the four most fundamental variables picked using the RF model can get
an alluring desire execution for mishaps. With the blend of the clustering computation and SVM
illustrate, the precision of the mishap desire model can be as high as 78.0%. Additionally, the outcomes
of the transferability of the three exceptional models propose that the variable assurance and gathering
estimation both have use for mishap desire. |
