background : the age standardized incidence rates of esophageal cancer in women and men in iran have the fifth and eighth ranks, respectively. due to the high incidence rate of esophageal cancer and the necessity of knowledge of its geographical distribution, the incidence of this cancer was mapped at province and county levels in the present study. methods: the study population of this empiric...

in this paper, using a one-dimensional simulation model, the reforming process of sour gas, i.e. ch4, co2, and h2s, to the various charged particles and syngas in a dielectric barrier discharge (dbd) reactor is studied. an electric field is applied across the reactor radius, and thus a non-thermal plasma discharge is formed within the reactor. based on the space-time coupled finite element meth...

Large volumes of dynamic stream data pose great challenges to its analysis. Besides its dynamic and transient behavior, stream data has another important characteristic: multi-dimensionality. Much of stream data resides at a multidimensional space and at rather low level of abstraction, whereas most analysts are interested in relatively high-level dynamic changes in some combination of dimensio...

This paper evaluates the security level of the River Keyak against the cube-like attack. River Keyak is the only lightweight scheme of the Keccak-permutation-based Authenticated Encryption Cipher Keyak, which is one of the 16 survivors of the 3rd round CAESAR competition. Dinur et al. gave the sevenround cube-like attack on Lake Keyak (1600-bit) using the divide-and-conquer method at EUROCRYPT ...

A partial-sum query obtains the summation over a set of specified cells of a data cube. We establish a connection between the covering problem in the theory of error-correcting codes and the partial-sum problem and use this connection to devise algorithms for the partial-sum problem with efficient space-time trade-offs. For example, using our algorithms, with 44 percent additional storage, the ...

An n-cube is the set of 2 points in n-dimensional Euclidean space and is often denoted by {0, 1}n. It is known that n-cube as a Cartesian product of pair of points is Ramsey, but no asymmetrical results are known. In this work we are concerned with bounds on the necessary dimension n of Euclidean space such that every r-coloring gives us monochromatic hypercube of some color and given dimension...

This project is a continuation of the PTAM (Parallel Tracking and Mapping for Small AR Workspaces) like approach solution [1]. Basically, it turned to be not an appropriate solution for recognizing full cube under not ideal illumination. Since the process might fail during the processing of any face out of six, it has to start from scratch, thus it will not be finished at all. On the contrary, ...

This paper introduces the concept of the smooth tGAP structure represented by a space-scale partition, which we term the space-scale cube. We take the view of 'map generalization is extrusion of data into an additional dimension'. For 2D objects the resulting vario-scale representation is a 3D structure, while for 3D objects the resulting vario-scale representation is a 4D structure. This paper...

The data cube, also known in the OLAP community as the multidimensional database, is designed to provide aggregate information that can be used to analyze the contents of databases and data warehouses. Previous research mainly focussed on strategies for supporting queries, assuming that updates do not play an important role and can be propagated to the data cube in batches. While this might be ...

A tensor-product higher-order space-time discontinuous-Galerkin method is extended to unstructured element shapes. The use of a tensor-product formulation is key to maintaining efficiency at high polynomial orders. The discrete system of equations arising at each space-time slab is solved using a Jacobian-free Newton-Krylov scheme. An alternatingdirection-implicit (ADI) preconditioner for hexah...
