    Full text link
    Security is one of the most important issues to force a lot of research and development effort in last decades. We are introduced a mining technique like firewall detection and frequent item set selection to enhance the system security in event management system. In addition, we are increasing the deduction techniques we have try to overcome attackers in data mining rules using our SIEM project. In proposed work to leverages to significantly improve attack detection and mitigate attack consequences. And also we proposed approach in an advanced decision-making system that supports domain expert’s targeted events based on the individuality of the exposed IWIs. Furthermore, the application of different aggregation functions besides minimum and maximum of the item sets. Frequent and infrequent weighted item sets represent correlations frequently holding the data in which items may weight differently. However, we need is discovering the rare or frequent data correlations, cost function would get minimized using data mining techniques. There are many issues discovering rare data like processing the larger data, it takes more for process. Not applicable to discovering data like minimum of certain values. We need to handle the issue of discovering rare and weighted item sets, the frequent weighted itemset (WI) mining problem. Two novel quality measures are proposed to drive the WI mining process and Minimal WI mining efficiently in SIEM system

    This paper addresses the characteristic extraction of hub protein based on Tumor Protein P53 whose properties are already established and known to have key functionalities. These characteristics can throw some light in the direction of hub classification in a cost effective manner. Current methods in this line use Gene Ontology database or sequence homology which are time consuming and complex. The proposed method uses a 420 element vector for the characteristic filtering of hub character from HPRD database and has shown some positive results

    1. The aim of this study was to evaluate the electroencephalographic (EEG) and behavioural responses of turkeys stunned with three different concussive non-penetrative captive-bolt guns prior to slaughter. 2. A total of 31 slaughter weight ex-breeding female turkeys (29 weeks of age; mean body weight 13.32 ± SD 0.65 kg) were stunned with the Cash Poultry Killer (CPK) (n = 10), Turkey Euthanasia Device (TED) (n = 10) and Zephyr EXL (n = 11). 3. Mean peak kinetic energy was highest for the CPK compared to the TED and Zephyr EXL (75.9 ± 4.5, 28.4 ± 0.4 and 24.4 ± 0.7 J, respectively). 4. A total of 29 (94%) of the turkeys were rendered unconscious following captive bolt stunning, with total power of the EEG (Ptot) significantly reduced from baseline values (reductions of 67% CPK, 84% TED and 76% Zephyr EXL, p < 0.01) and waveforms becoming isoelectric after periods of transitional EEG. However, two birds shot with the CPK and Zephyr EXL had periods of behavioural/reflexes (rhythmic respiration, nictitating membrane reflex, neck tension) and EEG activity (43–47 and 36–60 + s after the shot, respectively) indicating incomplete concussion and return of consciousness. In one bird, the shot was incorrectly positioned (Zephyr EXL), while the other appeared to be related to a defective cartridge (CPK). 5. In conclusion, all three captive bolt gun models were effective in producing unconsciousness in turkeys, provided they were positioned correctly and power loads performed according to their specifications.

    Extraction of bioactive compounds from medicinal plants permits demonstration of their physiological activity. It also facilitates pharmacology studies leading to discovery of synthesis of more potent drugs. The plant selected in the present study is Dioscorea oppositifolia L. (Dioscoreaceae) which is used traditionally for antiseptics, ulcers and abscesses. The root is chewed to cure toothache and aphthae. The whole plant extract is used for secondary syphilis and Psorasis. The present investigation was intended to evaluate the preliminary phytochemical characters and fluorescence analysis of this species

    Compressed full-field Fourier transform spectrometry

    Imaging Fourier transform spectrometry (IFTS) can be used for hyperspectral imaging in the wide-field mode. Wide-field hyperspectral imaging is a powerful technique for quantifying functional and morphological states of cells and tissues. Multiplexed fluoresce imaging, Multicolor spectral karyotyping of human chromosomes, spectral fluorescence resonance energy transfer(sp-FRET) and spontaneous Raman imaging are few examples. Unlike other hyperspectral imaging modalities, IFTS measures the Fourier transform of the spectrum of light at each pixel in the wide-field image, and traditionally, the inverse Fourier transform is used to extract the spectral information. The spectral recovery process (for each pixel) can be captured by a set of liner equations written in the matrix form below. Please click Additional Files below to see the full abstract

    Failure Analysis towards Reliable Performance of Aero-Engines

    Aero-engines are critical components whose reliable performance decides the primary safety of anaircrafthelicopter. This is met by rigorous maintenance schedule with periodic inspection/nondestructive testingof various engine components. In spite of these measures, failure of areo-engines do occur rather frequentlyin comparison to failure of other components. Systematic failure analysis helps one to identify root causeof the failure, thus enabling remedial measures to prevent recurrence of such failures. Turbine blades madeof nickel or cobalt-based alloys are used in aero-engines. These blades are subjected to complex loadingconditions at elevated temperatures. The main causes of failure of blades are attributed to creep, thermalfatigue and hot corrosion. Premature failure of blades in the combustion zone was reported in one of theaero-engines. The engine had both the compressor and the free-turbine in a common shaft. Detailedfailure analysis revealed the presence of creep voids in the blades that failed. Failure of turbine bladeswas also detected in another aero-engine operating in a coastal environment. In this failure, the protectivecoating on the blades was cracked at many locations. Grain boundary spikes were observed on these locations.The primary cause of this failure was the hot corrosion followed by creep damag

    Preformation Probability and Kinematics of Clusters Emission yielding Pb-daughters

    Full text link
    In the present study, the newly established preformation formula is applied for the first time to study the kinematics of the cluster emission from various radioactive nuclei, especially those decaying to the double-shell closure 208^{208}Pb nucleus and its neighbours as daughters. The recently proposed universal cluster preformation formula has been established based on the concepts that underscore the influence of the mass and charge asymmetry (ηA\eta_A and ηZ\eta_Z), cluster mass AcA_c and the Q-value, paving the way to quantify the energy contribution during the preformation as well as the tunnelling process separately. The cluster-daughter interaction potential is obtained by folding the relativistic mean-field (RMF) densities with the recently developed microscopic R3Y using the NL3∗3^* and the phenomenological M3Y NN potentials to compare their adaptability. The penetration probabilities are calculated from the WKB approximation. With the inclusion of the new preformation probability P0P_0, the predicted half-lives from the R3Y and M3Y interactions are in good agreement with the experimental data. Furthermore, a careful inspection reflects slight differences in the decay half-lives, which arise from their respective barrier properties. The P0P_0 for the systems with the double magic shell closure 208^{208}Pb daughter are found to be relatively higher with an order of ≈102\approx 10^2 than those with neighbouring Pb-daughter nuclei. By exploring the contributions of the decay energy, the recoil effect of the daughter nucleus is appraised, unlike several other conjectures. Thus, the centrality of the Q-value in the decay process is demonstrated and re-defined within the preformed cluster-decay model. Besides, we have introduced a simple and intuitive set of criteria that governs the estimation of recoil energy in the cluster radioactivity.Comment: 09 Pages, 06 Figures, and 01 Tabl
