Multipath transmission control protocol (MPTCP) has been proposed for devices with multiple network interfaces. This idea seems to be impossible for user implementation at the beginning of its proposal. However, the emergence of smartphones with multiple network access allows this idea to be implemented. This paper provides both theoretical and emp...

Investigating the potential for deploying a wind farm requires accurate knowledge of the vertical profile of wind speed (WS), both temporal and with height. Commonly, WS estimations at different heights involves calculating site‐dependent parameters such as roughness length, atmospheric conditions, and wind shear coefficient. This study proposes a...

With the advent of robust computing power, any sophisticated algorithm for data compression is becoming a trivial task. With more than petabytes of seismic data produced every day and the trend toward 4D survey, it is becoming essential to develop robust algorithms for the seismic data compression. This led to significant research efforts in data c...

Seismic data may undergo many types of distortions. However, the effect of distortion on raw data may not be apparent until the end of the standard processing of seismic reflection data. This paper presents a semi-blind metric for seismic data quality assessment, namely weighted normalized mean squared error (wNMSE). A weighting scheme is utilized...

This paper presents an investigation of the long short-term memory (LSTM) neural networks for seismogram time series prediction. LSTM has been widely used for time series prediction problems and achieved excellent results therefore it is interesting to utilize this technique for seismology. A seismogram from Albuquerque, New Mexico (Anmo), USA prov...
Chapter
In this work, we present a weighted l1 norm-based Extreme Learning Machine (ELM), namely, enhanced Regularized ELM (eRELM) for regression problems with outliers contaminated data. The enhancement includes the introduction of a weighting scheme based on l1 norm to a regularization term in the optimization problem. Seismogram is typically recorded wi...

The modern seismic acquisition produces a large data volume that significantly increases the cost of storage and transmission. Therefore, it is desirable to reduce the cost by compressing the seismic data. In this work, we propose a model-based compression scheme to deal with the large data volume. First, each seismic trace is modeled as a superpos...

This work develops a model-based compression scheme for seismic data. First, seismic traces are modeled as multitone sinusoidal waves superposition. Each sinusoidal wave is regarded as a model component and is represented by a set of distinct parameters. Second, a parameter estimation algorithm for this model is proposed accordingly. In this algori...

Text images are used in many types of conventional data communication where texts are not directly represented by digital character such as ASCII but represented by an image, for instance facsimile file or scanned documents. We propose a combination of Run Length Encoding (RLE) and Huffman coding for two dimensional binary image compression namely...

This paper develops a new framework for data compression in seismic sensor networks by using the distributed principal component analysis (DPCA). The proposed DPCA scheme compresses all seismic traces in the network at the sensor level. First of all, the statistics of the seismic traces acquired at all sensors are represented by a mixture model of...
Conference Paper
This work considers the data compression of sequential seismic sensor arrays. First, the statistics of the seismic traces collected by all the sensors are modeled by using the mixture model. Hence, a distributed Principle Component Analysis (PCA) compression scheme for sequential sensor arrays is designed. The proposed scheme does not require trans...

... Simple linear regression techniques can be used to predict the number of vaccinations. Linear prediction coding (LPC) [10], [11] differs from linear regression by the use of single dimensionality. LPC is usually applied to one dimension time series without taking other values as inputs. ...

... Bilateral filtering with Gaussian kernels has outperformed wavelet transform-based denoising, dictionary learning-based denoising and standard Bilateral filter with noise thresholding for seismic image denoising [18]. Motivated by this and its effectiveness in improving event detection for time-series non-intrusive load monitoring [19], we adopt and adapt a graph-based bilateral filter (GraphBF) with Gaussian kernel [20], which has never been tested for denoising of timeseries raw seismic signal recordings. ...
... Deep learning methods are widely used to solve the seismic compression problem. Restricted Boltzmann machine (RBM) [14] with single layer neural network is proposed in Nuha et al. [15]. Although being computationally efficient, a single layer cannot capture all data features and the reconstruction error is high. ...

... They all rely on the observation that the covariance matrix can be computed exactly at the global server by adding up the local covariance matrices. This basic version is, for instance, used in Liu et al. (2018). In this version, the covariance matrices of the local datasets are computed and sent to the aggregator. ...
... The results showed that the proposed scheme can extract the information from both seismic reflection layers and neighboring traces. More recently, a distributed principal component analysis (DPCA) compression was proposed for smart seismic acquisition networks in [32] and [33], wherein the overall statistics of the seismic traces recorded by all sensors in the acquisition network are used for global PC estimation. In [34], the nonlinearities of seismic traces were investigated and extended by using a five-layer autoassociative neural network model to improve seismic interpretation. ...
