Hot-in-place recycling of asphalt pavement is one the important regeneration technologies engineering, which apply to pavements with fewer diseases, excellent driving quality, slight rutting, and good structural strength. However, surface layer some road sections was aging, penetration index aged at 25°C lower than 20(0.1mm), does not meet recommended requirements criterion in China. In 2019, 3...

A measurement 1,2 is presented of diffractive dijet production in deep-inelastic scattering (DIS) interactions at HERA of the type ep→ eXY , where the X system is separated by a large rapidity gap from a low-mass leading baryonic system Y . The data are consistent with QCD factorisation in diffractive DIS and yield tight constraints on both shape and normalisation of the diffractive gluon distr...

Abstract The general integer mapping theory of invertible linear transforms is considered in this paper. Two terms of integer factor and elementary triangular matrix are introduced. We prove that there exists an integer implementation if a linear transform is invertible and in finite dimensional space. The integer implementation of an invertible linear transform has several advantages such as (...

The paper presents a simple, linear time, in-place algorithm for performing a 2-way in-shuffle which can be used with little modification for certain other k-way shuffles.

The (k,n)-perfect shuffle, a generalisation of the 2-way perfect shuffle, cuts a deck of kn cards into k equal size decks and interleaves them perfectly with the first card of the last deck at the top, the first card of the second-to-last deck as the second card, and so on. It is formally defined to be the permutation ρk,n : i→ ki (mod kn + 1), i ∈ {1,2, . . . ,kn}. We uncover the cycle structu...

One of the classic data structures for storing point sets in R is the priority search tree, introduced by McCreight in 1985. We show that this data structure can be made in-place, i.e., it can be stored in an array such that each entry only stores one point of the point set. We show that the standard query operations can be answered within the same time bounds as for the original priority searc...

Omni-directional locomotion systems are yet of little advantage in virtual environments (VEs) with limited large display system, where users may experience visualless situations when they move in a direction that is not covered by the large screen. This paper presents a new omni-directional locomotion interface based on step-inplace movement and a smart-turntable system to impart users with the...

Currently there is limited evidence linking age-friendly characteristics to outcomes in elders. Using a representative sample of 1,376 adults aged 60 and older living in Detroit, this study examined the association between age-friendly social and physical environmental characteristics and the expectation to age in place, and the potential differences between low- and higher-income elders. Based...

Every permutation of {1, 2, . . . , N} can be written as the product of two involutions. As a consequence, any permutation of the elements of an array can be performed in-place using simultaneous swaps in two rounds of swaps. In the case where the permutation is the k-way perfect shuffle we develop two methods for efficiently computing the pair of involutions that accomplishes these swaps. The ...
