Numerical Simulation on the Basic Rules of Multihole Linear Codirectional Hydraulic Fracturing by Weiyong Lu, Yonglong Wang, Xin Zhang

“…Multihole codirectional hydraulic fracturing is influenced by the angle between the direction of the hole distribution and maximum principal stress, the difference of the principal stress, and the spacing of the boreholes. The smaller the angle, the difference value of the principal stress, and the hole spacing, the better the multihole codirectional hydraulic fracturing effect.…”

GROTHENDIECK RINGS OF DEFINABLE SUBASSIGNMENTS AND EQUIVARIANT MOTIVIC MEASURES by Quy Thuong Le

“…This paper studies categories of definable subassignments with some category equivalences to semi-algebraic and constructible subsets of arc spaces of algebraic varieties. These equivalences lead to the identity of certain Grothendieck rings, which allows us to compare the motivic measure of Cluckers-Loeser with that of Denef-Loeser for certain classes of definable subassignments.…”

Existence of Mild Solutions to Nonlocal Fractional Cauchy Problems via Compactness by Rodrigo Ponce

“…We obtain characterizations of compactness for resolvent families of operators and as applications we study the existence of mild solutions to nonlocal Cauchy problems for fractional derivatives in Banach spaces. We discuss here simultaneously the Caputo and Riemann-Liouville fractional derivatives in the cases 0<α<1 and 1<α<2.…”

Framing the Land: Canadian Landscapes Revisited in Jin-me Yoon and Lorraine Gilbert’s Photography by Gwendolyne Cressman

“…I will be looking at the ways in which two contemporary Canadian photographers, Jin-me Yoon and Lorraine Gilbert, have revisited earlier landscapes in their works and how, through various processes of reframing, they reveal and contest the political, social and ecological underpinnings active in the production of these spaces. I will be paying attention to the critical visual investigation they deploy around Nordic landscapes defined not as the abstract spaces of the nation but as the places where issues of identity and memory unfold.…”

Optimization mechanism of attack and defense strategy in honeypot game with evidence for deception by Lihua SONG, Yangyang JIANG, Changyou XING, Guomin ZHANG

“…Using game theory to optimize honeypot behavior is an important method in improving defender’s trapping ability.Existing work tends to use over simplified action spaces and consider isolated game stages.A game model named HoneyED with expanded action spaces and covering comprehensively the whole interaction process between a honeypot and its adversary was proposed.The model was focused on the change in the attacker’s beliefs about its opponent’s real identity.A pure-strategy-equilibrium involving belief was established for the model by theoretical analysis.Then, based on the idea of deep counterfactual regret minimization (Deep-CFR), an optimization algorithm was designed to find an approximate hybrid-strategy-equilibrium.Agents for both sides following hybrid strategies from the approximate equilibrium were obtained.Theoretical and experimental results show that the attacker should quit the game when its belief reaches a certain threshold for maximizing its payoff.But the defender’s strategy is able to maximize the honeypot’s profit by reducing the attacker’s belief to extend its stay as long as possible and by selecting the most suitable response to attackers with different deception recognition abilities.…”

Stability of a weighted L2 projection in a weighted Sobolev norm by Averseng, Martin

“…We prove the stability of a weighted $L^2$ projection operator onto piecewise linear finite elements spaces in a weighted Sobolev norm. Namely, we consider the orthogonal projections $\pi _{N,\omega }$ from $L^2(\mathbb{D},1/\omega (x)\mathrm{d}x)$ to $\mathcal{X}_N$, where $\mathbb{D} \subset \mathbb{R}^2$ is the unit disk, $\omega (x) = \sqrt{1 - \vert x\vert ^2}$ and the spaces $(\mathcal{X}_N)_{N \in \mathbb{N}}$ consist of piecewise linear functions on a family of shape-regular and quasi-uniform triangulations of $\mathbb{D}$. …”

Research on Drilling and Sealing Technology for Cross Bedding of Superthick Coal Seam by Yao-bin Li, Cai-Hao Yue, Xin Guo

“…Through the simulation and comparison of gas pressure at different extraction time and the gas pressure changes when the spacing of boreholes is 8 m, 10 m, and 12 m, the results show that, under the designed parameters, when the pressure value at the middle of the two boreholes starts to be less than 0.74 Mpa, the standard extraction time of the upper and lower cross strata boreholes is 160 days, and the most suitable spacing of boreholes is 10 m. …”

Urban redevelopment, governance and vulnerability: thirty years of ‘regeneration’ in Dublin by Niamh Moore-Cherry

“… Over the last three decades, state intervention through urban regeneration has focused on ‘fixing’ perceived social and spatial vulnerabilities within particular neighbourhoods, communities or city spaces but has often generated new urban crises. Previous research examining regeneration over significant periods of time in the UK and Ireland, suggests that often the same spaces and communities are subject to repeated rounds of intervention. …”
