Lubrication is a system where all moving machine parts need to be
lubricated, in order to avoid direct friction between the components can cause the
most damage. In motor fuel lubricity do thorough all of the moving parts, and
therefore required the maximum pressure in supporting the work of the auxiliary
engine. The pressure should reach a value of 4.0 to 4.5 kg / cm2 to achieve
maximum lubrication. This prevents the engine when the auxiliary overloaded
then the pressure was not until approaching the limit poor lubrication and an
alarm occurs at a pressure of 3.7 kg / cm2. The author formulates the problem by
searching for the factors of the decline in the cylinder liner lubrication systems,
lubrication systems the impact of falling cylinder liner, and the efforts taken to
address the decline in the cylinder liner lubrication system.
The author summarizes the problems and try to solve the problem by
using the method of hazard operability is with a systematic way of analyzing the
risk of a system whereby the operating activities of potential problems in a system
that is identified using a circuit.
There are many causes less optimal lubrication system maintenance on
auxiliary engines. Among them is happening in MV. Energy Prosperity, of causes
found. In MV. Energy Prosperity less optimal lubrication system so that the
pressure lubricating oil is not normally caused by problems with filters and pumps
and piston cooling case cover, filters and pumps is a component of risky
impending penurunanan pressure and also the influence of the components of the
piston cooling case cover, though not too conspicuous in its work it can cause
lubricating oil pressure is not normal.

Mitigation of the effect of Standard Networks Attacks in SSL Encrypted Traffic by Encrypted Traffic Analysis
No full textWith increased use of encryption, cyber threat landscape is changing. For general public this transition shifts to more private and safer internet experiences, but at the same time it is a serious concern for security personnel now. For them it hinders control over the traffic moving on their network and poses difficulty in traffic analysis and management. Security personals are interested in knowing how the network is being accessed, whether or not that traffic contains some malware and is safe enough and compliant with your organization’s policies. This project is not about decrypting the encrypted content of the packet’s payload as it will highly degrade network performance plus some advanced encryption algorithms like AES are assumed to be perfect. So the aim of this project is to analyze encrypted traffic and find out some interesting patterns without the need for bulk decryption. The analysis will be based on flow based features and metadata. Encrypted Traffic Analytics maintains the integrity of the encrypted flow and doesn’t affect the privacy of users
Designing a Pagerank based Prototype Search Engine
No full textIn this paper the challenges faced during building a prototype of a search engine have been discussed. Each component of a search engine has been described in details. Architectures for each module have been proposed that is most appropriate according to our research on search engine technology and their implementation details have also been provided. . Several algorithms had been designed and implemented for each of the component but pre-built technologies were also used like Pagerank. As Google’s Pagerank [1] algorithm is also embedded in our search engine (although in a small scale), thus its explanation is also provided along with the implementation details
Analysis of SIR Epidemic Models
No full textModeling epidemics has played a vital role in predicting the impact of a disease in a population and the ability to overcome it. The objective of this paper is to introduce the concept of agent based modeling classification for SIR epidemic model, suggest a new discrete-time agent based SIR model and formally document Gillespie’s Algorithm based SIR epidemic model. Furthermore a computational analysis of chemical master equation and Gillespie’s algorithm based SIR modelshas been performed showing that the use of latter results in considerable reductionin execution tim
Industrial Control and Building Automation System Penetrating Testing using Modbus TCP Testbed
No full textIndustrial Control System (ICS) plays a vital role in industries as it controls industrial processes such as power plants, food production, transportation, water and gas distribution etc. Similarly Building Automation System (BAS) is utilized for control, energy efficiency and conservation of modern buildings. As both BAS and ICS systems are becoming increasingly interconnected with networking technologies and becoming a lucrative target for attacks thus pose a serious threat to the infrastructure they control. ICS and BAS networks have been using legacy protocols with implementation of ICT protocols and technologies to be connected with modern networks. Thus, they have lack of security implementation. This paper presented a test-bed for testing vulnerabilities in Modbus protocol on HVAC control system. Two MITM attack scenarios were discussed and performed to demonstrate the weakness in the Modbus TCP protocol. The proposed system was tested using EasyIO-FS-32 server class controller having Modbus RTU, TCP and BACnet MSTP, TCP
PARALLEL LOSSLESS IMAGE COMPRESSION USING MPI
No full textIn lossless compression techniques, perfectly identical copy of the original image can be reconstructed from the compressed image. The paper implements three lossless compression techniques namely Huffman Encoding, Run Length Encoding and DPCM techniques using MPI. The experimental results show considerable reduction in execution time and better compression ratio for certain types of images
