In this paper a forecasting method has been mentioned that is contingent on a hybrid empirical mode decomposition (EMD) and Extreme Learning Machine (ELM). The non stationary time series is further decomposed into distinct intrinsic mode functions (IMF). A short term forecasting is also carried out in this work to prove the accuracy of the given model. This model is implemented in MATLAB/SCRIPT environment.","PeriodicalId":208028,"journal":{"name":"2017 International Conference on Circuit ,Power and Computing Technologies (ICCPCT)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127928480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although, there are numerous protection systems such as firewalls and intrusion detection and prevention system, and anti-viruses that are developed to protect cloud infrastructures and services from severe attacks, but still the risk of criminal activities exists. This lead to attract the attention of researchers and scientists around the world to digital forensic which is a science to aid law enforcement officers and digital investigator to identify, collect and analyze digital footprints or evidence which are collected from a crime scene. One of the significant sources of as a digital evidence in the cloud is log data because they frequently connect events in certain time. The process of log data forensics mitigates the investigation process by identifying the malicious behavior and reveal the hidden malicious activities. Cloud log analysis can help to reconstruct cybercrime events which occurred in the cloud. Traditional log data analysis procedures and tools can be adapted to cloud through using new fast on memory computing platforms such as Apache Spark. Spark is a general-purpose cluster-computing engine, which is very fast and reliable. This paper presents analysis approach for batch and stream log data using Apache Spark. The results show that Spark can be used as a fast platform for handling the diverse large size of log data and extract useful information that can assist digital investigators in the analysis immense amount of generated cloud log data in a given frame of time. Furthermore, the results can make provision to reconstruct and generate a timeline related to historical past sequence events occurred during a cloud crime as well as identify the malicious user's IP address, date and time, with a number of accesses.","PeriodicalId":208028,"journal":{"name":"2017 International Conference on Circuit ,Power and Computing Technologies (ICCPCT)","volume":"131 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116896901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

That contributes approximately 2.8% to 3% of annual global greenhouse gas emissions, especially CO2. The marine transportation is expected to increase further more as energy demand is expected to grow by 25% from 2014 to 2040. Environmental concerns for the reduction of CO2 emission compel the shipping industry to reduce fossil fuel consumptions by increasing efficiency in shipping transportation and by adopting renewable energy sources for shipping. Wind energy for ship transportation is abundant and its potential is also high on seas. Wing sails, Airborne wind turbines, Wind kites, Flettner rotors, etc. are different techniques to harness wind energy for shipping. Flettner Rotor technique is one which provide thrust force for propelling the ship. In this paper, a cylindrical Flettner rotor (without endplates) of 12.5 m height and 2.1 m diameter is used for the theoretical analysis to estimate net power generation by Flettner rotor using the values of lift coefficient of Cl = 12.5 and drag coefficient of Cd = 0.2. Calculations have been made for ship speeds of 15 knots and 20 knots and wind speed variation from 5 m/s to 20 m/s at all true wind angles. Net power output obtained is maximum at true wind angles of 100 degree and 260 degree. At ship speed of 15 knots, the maximum values of net power obtained is 42.2 kW, 124 kW, 239.9 kW and 386.7 kW at wind speeds of 5 m/s, 10 m/s, 15 m/s, 20 m/s respectively. Whereas, at ship speed of 20 knots maximum values of net power is 68.2 kW, 189.5 kW, 358.8 kW and 575.2 kW at wind speeds of 5 m/s, 10 m/s, 15 m/s, 20 m/s respectively.

Ghosh","doi":"10.1109/ICCPCT.2017.8074353","DOIUrl":"https://doi.org/10.1109/ICCPCT.2017.8074353","url":null,"abstract":"Aditya Tokamak is a fusion reactor for obtaining nuclear fusion energy from high temperature, ionized gas called plasma. The magnetic field is used to confine plasma in the shape of torus. A disruption is a violent event that terminates magnetically confined plasma. In a disruption, the temperature drops drastically and heat particles are released from confinement on a short timescale and dumped on the vessel wall, causing damage in proportion to the stored energy. The loss of confinement is associated with the production of runaway electrons, which may also produce damage. In order to mitigate disruption, it is necessary for early prediction of disruption. The signals like Halpha, Hard X ray, Plasma current, Mirnov coil signal, Vloop, Soft X-ray should be analyse for the detection of plasma disruption. From the signal if there is any peak in the Halpha, Hard X ray and the non negative value appears in Vloop signals before the decayed of the plasma current indicates the disruption. There are hard and soft disruptions. Since the hard disruption is dangerous, methods like Artificial Neural Network (ANN) using mmultilayer perception and the Fast Fourier Transform (FFT) where already used to find the disruption in terms of frequency component signals. Since Aditya Tokamak signals are non stationary, the above mentioned methods for stationary signal, so those methods are not providing correct and satisfactory results. In this work, different wavelet transforms like Daubechies, Discrete Meyer, Symlets and Biorthogonal were applied on the signal and the corresponding approximation and detailed coefficients were obtained from all the signals in order to obtain the disruption. On an average, of thirty signals are used from different shots for the analysis. Out of the above mentioned wavelet transforms, Discrete meyer and Biorthogonal wavelet are providing the better results than others in terms of the statistical parameters such as mean, skewness and kurtosis. Mean is minimum and the skewness and kurtosis are maximum in the disruption signal, which is confirmed with its time domain analysis. Discrete meyer and the Biorthogonal wavelet transforms provide the spectral information in contrast to frequency domain approaches like FFT. It provides early information about the hard disruption. Wavelet transform is better than FFT and ANN. Since the range of parameters responsible for disruption is not fixed by this method the analysis can be strengthened with Framelet transform.","PeriodicalId":208028,"journal":{"name":"2017 International Conference on Circuit ,Power and Computing Technologies (ICCPCT)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123415900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
