In ARX structures, constants that are not rotational invariant are often injected into the state, in the form of round constants or as a result of using a fixed key. Rotational cryptanalysis cannot deal with such constants. Rotational cryptanalysis in the presence of constants, also known as rotational-XOR cryptanalysis, is a recently proposed statistical technique to attack ARX primitives. The...

Enhancing on line analytical processing through efficient cube computation plays a key role in Data Warehouse management. Hashing, grouping and mining techniques are commonly used to improve cube pre-computation. BitCube, a fast cubing method which uses bitmaps as inverted indexes for grouping, is presented. It horizontally partitions data according to the values of one dimension and for each r...

Rubik’s Cube is an easily-understood puzzle, which is originally called the “magic cube”. It is a well-known planning problem, which has been studied for a long time. Yet many simple properties remain unknown. This paper studies whether modern SAT solvers are applicable to this puzzle. To our best knowledge, we are the first to translate Rubik’s Cube to a SAT problem. To reduce the number of va...

The pre-computation of data cubes is critical to improving the response time of On-Line Analytical Processing (OLAP) systems and can be instrumental in accelerating data mining tasks in large data warehouses. However, as the size of data warehouses grows, the time it takes to perform this pre-computation becomes a significant performance bottleneck. This paper presents an improved parallel meth...

In this paper, we present significant advances of the novel meccano technique to construct adaptive tetrahedral meshes of 3-D complex solids. Specifically, we will consider a solid whose boundary is a surface of genus 0, i.e. a surface that is homeomorphic to the surface of a sphere. In this particular case, the automatic procedure is defined by a surface triangulation of the solid, a simple me...

In the 21st century, researchers have been showing keen interest in areas of wireless networking and internet things (IoT) devices. Conventionally, batteries used to power these networks; however, due limited lifespan with recent advancements piezoelectric technology, there is a dramatic increase renewable energy harvesting this research, an eco-friendly wind device based on technique analytica...

This correspondence discusses an extension of the well-known phase correlation technique to cover translation, rotation, and scaling. Fourier scaling properties and Fourier rotational properties are used to find scale and rotational movement. The phase correlation technique determines the translational movement. This method shows excellent robustness against random noise.
