In this paper, we investigate the use of widely linear processing in multiple-input multiple-out (MIMO) systems employing filter bank based multi-carrier with offset quadrature amplitude modulation (FBMC/OQAM). The concept of a twostep receiver combining linear processing and widely linear processing is presented. In the first step we cancel the intrinsic interference that prevents us from expl...

This paper uses the supervised learning techniques of linear regression and support vector machines in an attempt to predict the merging behavior of drivers on U.S. Highway 101 based on current traffic patterns. Using highway data from the Federal Highway Administration, the paper approaches the problem from numerous angles, eventually concluding that using a twostep approach achieves the best ...

This paper describes an approach based on the shortest path method for the detection and tracking of vibrating lines. The detection and tracking of vibrating structures, such as lines and cables, is of great importance in areas such as civil engineering, but the specificities of these scenarios make it a hard problem to tackle. We propose a twostep approach consisting of line detection and subs...

We consider a diffusional-thermal model with twostep competitive reactions for premixed combustion wave propagation in one spatial dimension. Numerical investigation of the flame speed of the system for different fuel types shows the existence of regions where two stable travelling combustion wave solutions co-exist solutions pertaining to the fast and slow branches. A hysteresis type phenomena...

This paper presents the first study using neural machine translation (NMT) for grammatical error correction (GEC). We propose a twostep approach to handle the rare word problem in NMT, which has been proved to be useful and effective for the GEC task. Our best NMTbased system trained on the CLC outperforms our SMT-based system when testing on the publicly available FCE test set. The same system...

O presente estudo, realizado em Portugal, segue uma abordagem quantitativa, com o objetivo de analisar a probabilidade ocorrência churning recursos humanos no setor privado e público. Esta pesquisa sobre visa contribuir para desenvolvimento um tema ainda pouco explorado, por meio do incremento da literatura assunto aumento estudos empíricos. Como método coleta dados, recorreu-se à aplicação que...

This paper empirically evaluates the usefulness of the Two-Step approach for transforming continuous variables toward normality. The study uses 27 corporate financial performance (CFP) variables on 39,216 US corporations to compare three variable sets: 1) random-normal, 2) original, and 3) transformed toward normality using the Two-Step. The results of several statistical procedures relevant to...
