Abstract. Previously, self-dual codes have been constructed from weighing matrices, and in particular from conference matrices (skew and symmetric). In this paper, codes constructed from matrices of skew symmetric type whose determinants reach the EhlichWojtas’ bound are presented. A necessary and sufficient condition for these codes to be self-dual is given, and examples are provided for lengt...

This paper addresses the DATA-DIFF problem: given a dataset and a subsequent version of the dataset, find the shortest sequence of operations that transforms the dataset to the subsequent version, under a restricted family of operations. We consider operations similar to SQL UPDATE, each with a condition (WHERE) that matches a subset of tuples and a modifier (SET) that makes changes to those ma...

In this work we consider a stabilized Lagrange multiplier method in order to approximate the Coulomb frictional contact model in linear elastostatics. The particularity of the method is that no discrete inf-sup condition is needed. We study the existence and the uniqueness of solution of the discrete problem.

Let k be an algebraically closed field of positive characteristic, G a reductive group over k, and V a finite dimensional G-module. Let P be a parabolic subgroup of G, and UP its unipotent radical. We prove that if S = SymV has a good filtration, then SUP is strongly F -regular.

Update summarization is an emerging summarization task of creating a short summary of a set of news articles, under the assumption that the user has already read a given set of earlier articles. In this paper, we propose a new co-ranking method to address the update summarization task. The proposed method integrates two co-ranking processes by adding strict constraints. In comparison with the o...

We study the issue of convergence of user rates and resource prices under a family of rate controlschemes called dual algorithms with arbitrary communication delays. We first consider a case where asingle resource is shared by many users. Then, we study a general network shared by heterogeneoususers and derive sufficient conditions for convergence. We show that in the case of a ...

ions ( other country GW  ) were downscaled to grid level ( other cell GW  ) based on proportion of each cell water use in other sector ( MAgPIE Other WU  ) to country total water use in other sectors (( MAgPIE Other WU  )Country) as obtained from the MAgPIE model results. In the final step, downscaled grid level groundwater abstractions for agriculture and other sectors were addded to get t...

Predicting the interestingness of images or videos can greatly improve people’s satisfaction in many applications, such as video retrieval and recommendations. In this paper, we present our methods in the 2017 Predicting Media Interestingness Task. We propose deep ranking model based on aural and visual modalities which simulates the human annotation procedures for more reliable interestingness...

The reaction process A + B → ∅ is modelled for ballistic reactants on an infinite line with particle velocities vA = c and vB = −c and initially segregated conditions, i.e. all A particles to the left and all B particles to the right of the origin. Previous models of ballistic annihilation have particles that always react on contact, i.e. pair-reaction probability p = 1. The evolution of such s...
