A Decomposition-Based Approach for the Multiperiod Multiproduct Distribution Planning Problem by S. Ahmad Hosseini, Güvenç Şahin, Tonguç Ünlüyurt

“…We address the most general case of multiperiod, multiproduct network planning problems, where we allow spoilage on arcs and storage at nodes. In our models, all network parameters change over time and products. …”

Design of Reverse Curves Adapted to the Satellite Measurements by Wladyslaw Koc

“…The method may be particularly useful in the situations when both tangents cannot be connected in an elementary way using a circular arc with transition curves. Thus, the only solution would be the application of two circular arcs of opposite curvature signs, that is, the use of an inverse curve. …”

Gouvernance touristique des grandes stations et durabilité. Une lecture en termes de proximité by Emmanuelle Marcelpoil, Vincent Boudières

“…Such a comprehension makes it possible to encourage forms of negotiation and to create the conditions of local scenes of discussion on becoming to it stations. The stations of the Arcs, of Val d’Isère in Savoy will illustrate the diversity of the methods of articulation between proximities organisational and cognitive, in varied territorial contexts.…”

Profile Shaped-configuration of Convex Ellipse Rotor and Its Following High-shape Technology by Xiangjun Yang, Fuchun Sun

“…Finally， all parameter coordinate equations of raised shaped-profiles are provided， and the comparative advantage results of raised rotor to common circular arc rotor is focused on. All results show that the elliptical arc foundation rotor and high-profile rotor profile construction method have significant improvement in both high yield and leakage prevention effects， and the fundamental problem of the optimal axial length ratio and maximum shape factor of the arcs arc of the Roots pump is solved.…”

Extension du champ télécinématographique de la science-fiction. The Mandalorian (Disney+) by Hannedouche Cédric

“…These series are therefore part of a process of renewal of the genre by upsetting serial standardization (unequal duration of episodes, varied tones, creation of new narrative arcs, etc.) and in turn pose themselves as laboratories of science fiction telecine to come. …”

Efficient Algorithms on Multicommodity Flow over Time Problems with Partial Lane Reversals by Urmila Pyakurel, Shiva Prakash Gupta, Durga Prasad Khanal, Tanka Nath Dhamala

“…The multicommodity flow problem arises when several different commodities are transshipped from specific supply nodes to the corresponding demand nodes through the arcs of an underlying capacity network. The maximum flow over time problem concerns to maximize the sum of commodity flows in a given time horizon. …”

High-Accuracy and Efficient Simulation of Numerical Control Machining Using Tri-Level Grid and Envelope Theory by Zhengwen Nie, Yanzheng Zhao

“…To calculate the instantaneous engagement region, the immersion angles are obtained by fusing the intersection points between the bottom-level voxel edges and the cutter surface, which are then trimmed by feasible contact arcs determined using envelope theory. In a series of test cases, the proposed method shows higher efficiency than the tri-dexel model and stronger applicability in high-precision machining than the two-level grid.…”

Composite Operator Method Analysis of the Underdoped Cuprates Puzzle by Adolfo Avella

“…Given this recipe and exploiting the few unknowns to enforce the Pauli principle content in the solution, it is possible to qualitatively describe some of the anomalous features of high-Tc cuprate superconductors such as large versus small Fermi surface dichotomy, Fermi surface deconstruction (appearance of Fermi arcs), nodal versus antinodal physics, pseudogap(s), and kinks in the electronic dispersion. …”
