Rotational cryptanalysis is a statistical method for attacking ARX constructions. It was previously shown that ARX-C, i.e., ARX with the injection of constants can be used to implement any function. In this paper we investigate how rotational cryptanalysis is affected when constants are injected into the state. We introduce the notion of an RX-difference, generalizing the idea of a rotational d...

In this study, an ARX model with nonparametric multi time scale regression model was proposed for short term gust forecasting and applied to a ski resort in Japan. Proposed ARX model can be used for short term forecasting of mean and fluctuating wind speed. Proposed nonparametric multi time scale regression model can appropriately estimate the peak factor and shows better agreement with the mea...

Infantile spasms are a catastrophic form of pediatric epilepsy with inadequate treatment. In patients, mutation of ARX, a transcription factor selectively expressed in neuronal precursors and adult inhibitory interneurons, impairs cell migration and causes a major inherited subtype of the disease X-linked infantile spasms syndrome. Using an animal model, the Arx((GCG)10+7) mouse, we determined ...

Quantitative modeling is an important tool for research on complex physiological systems. Mathematical model are playing important role in analyzing complex system. In order to create an accurate model and significant interpretations, system identification techniques are needed. An optimized auto-regressive model based on Sequential Genetic algorithm (Sequential GA) is investigated in this stud...

Industrial process control systems commonly exhibit features of time-varying behavior, strong coupling, and nonlinearity. Obtaining accurate mathematical models these nonlinear achieving satisfactory performance is still a challenging task. In this paper, data-driven modeling techniques deep learning methods are used to accurately capture category smooth system’s spatiotemporal features. The op...

We propose the first adaptation of Matsui’s algorithm for finding the best differential and linear trails to the class of ARX ciphers. It is based on a branch-and-bound search strategy, does not use any heuristics and returns optimal results. The practical application of the new algorithm is demonstrated on reduced round variants of block ciphers from the Speck family. More specifically, we rep...

An integrated modeling and robust model predictive control (MPC) approach is proposed for a class of nonlinear systems. First, the nonlinear system is identified off-line by a RBF-ARX model possessing linear ARX model structure and state-dependent Gaussian RBF neural network type coefficients. On the basis of the RBF-ARX model, a combination of a local linearization model and a polytopic uncert...

In this paper, we study linear cryptanalysis of the ARX structure by means of automatic search. To evaluate the security of ARX designs against linear cryptanalysis, it is crucial to find (round-reduced) linear trails with maximum correlation. We model the problem of finding optimal linear trails by the boolean satisfiability problem (SAT), translate the propagation of masks through ARX operati...
