In this paper we propose a new approach for Big Data mining and analysis. This new approach works well on distributed datasets and deals with data clustering task of the analysis. The approach consists of two main phases: the first phase executes a clustering algorithm on local data, assuming that the datasets was already distributed among the system processing nodes. The second phase deals wit...

The paper presents a data-driven approach to information extraction (viewed as template lling) using the structured language model (SLM) as a statistical parser. The task of template lling is cast as constrained parsing using the SLM. The model is automatically trained from a set of sentences annotated with frame/slot labels and spans. Training proceeds in stages: rst a constrained syntactic pa...

The complex solidification dynamics and thermal cycling during Selective Laser Melting process is expected to result in non-equilibrium material characteristics. There is an essential need for characterization techniques which are critical towards the estimation of anisotropies. The current investigation is targeted towards establishing tensile testing methodologies and their relation to differ...

The cosmic microwave background (CMB) is one of only a few physically observable remnants of the early Universe. Studies of the spectrum, polarization and spatial distribution of the CMB can potentially lead to a detailed understanding of the processes that took place in the early Universe. Many of the outstanding cosmological questions regarding the age, contents, future, and large scale dynam...

The application of digital holography as a viable solution to 3D capture and display technology is examined. A review of the current state of the field is presented in which some of the major challenges involved in a digital holographic solution are highlighted. These challenges include (i) the removal of the DC and conjugate image terms, which are features of the holographic recording process,...

In this paper, the maximum Peak-toAverage Power Ratio (PAR) as well as the PAR distribution of Wavelet-OFDM in discrete-time domain is derived. Furthermore, the PAR reduction method Selected Mapping (SLM) is adapted to this OFDM technique, presenting both on optimum and a lowcomplexity algorithm. All results are compared to their well-known counterparts in conventional CyclicPrefix OFDM.

Several properties of OFDM has made it an essential modulation scheme for high speed transmission links. But one major drawback ofOFDM is its large Peak-toaverage power ratio. Here we have reviewed some of the PAPR reduction techniques and compared the performance of clipping and filtering,partial transmit sequence and selected mapping methods for QAM modulated OFDM. We have also shown analytic...

This paper presents a successful technique for creating a new language model (LM) that adapts the original target LM used by a machine translation (MT) system. This technique is especially useful for situations where there are very scarce resources for training the target side (Spanish Sign Language (LSE) in our case) in order to properly estimate the target LM, the Sign Language Model (SLM), u...

The application of OFDM within a multi-user downlink scenario is considered. Thereby, two problems occur. First, due to OFDM, the transmit signal exhibits a large peak-to-average power ratio (PAR). Second, the multi-user interferences have to be equalized (or precoded) at the transmitter side. In this article, we address combined precoding and PAR reduction. As precoding schemes sorted Tomlinso...
