Distributed denial of service (DDoS) is a fundamental security problem in the ISP layer internet things. However, most existing DDoS detection methods are based on NetFlow data, which cannot handle huge delay flow generation and massive network traffic. Besides, it extremely hard to obtain real attack traffic construct traditional supervised binary classification model. To solve these problems,...

In this paper, the vibration characteristics of multi-layer shell that internal and external surfaces with a layer of piezoelectric sensor and actuator is investigated. The backrest shell laminated with simple analytical method to evaluate and the results were compared with results obtained by other researchers. The numerical solution methods (GDQ) for shells with piezoelectric layers and plain...

—Energy efficient multiple-input multiple-output (MIMO) with beamforming is one of the splendid ways to increase throughput in wireless networks. The existing schemes have focused on multi layer for multi-user. However, when multi layers for multi-user is implemented on wireless networks the system performance degrades in term of energy consumption, time and processing. The single layer multi-...

Soft X-rays excite the inner shells of materials more efficiently than any other form light. The investigation synchrotron radiation (SR) processes using inner-shell excitation requires beamline to supply a single-color and high-photon-flux light in soft X-ray region. A new integrated computing multi-layered-mirror (MLM) monochromator was installed at 07A (BL07A) NewSUBARU, which has 3 m undula...

The theory of the goodness of fit procedures for multivariate normality based on spherical harmonics, introduced in [6], is extended to cover the context of the multivariate linear model (MLM). The limiting distribution of the statistics considered does depend on the distribution of the covariates in the MLM, and our results provide a complete description of the manner in which the covariate di...

A chaotic orbit generated by a nonlinear system is irregular, aperiodic, unpredictable and has sensitive dependence on initial conditions. However, the chaotic trajectory is still not well enough to be a crypto system in digital secure communication. Therefore, we propose a Modified Logistic Map (MLM) and give a theoretical proof to show that the MLM is a chaotic map according to Devaney’s defi...

A new Markov-based method for real time prediction of network transmission time delays is introduced. The method considers a Multi-Layer Perceptron (MLP) neural model for the transmission network, where the number of neurons in the input layer is minimized so that the required calculations are reduced and the method can be implemented in the real-time. For this purpose, the Markov process order...

| The problem of estimating the parameters of complex-valued sinusoidal signals (cisoids, for short) from data corrupted by colored noise occurs in many signal processing applications. We present a simple formula for the asymptotic (large-sample) Cram er-Rao bound (CRB) matrix associated with this problem. The maximum likelihood method (MLM), which estimates both the signal and noise parameters...
