With installation of positive train control (PTC) on many U.S. rail corridors, Class I railroads may soon leverage these investments in communications network infrastructure to implement “advanced PTC” systems incorporating moving blocks.

Abstract:

Within a global physical theory, a notion of locality allows us to find and justify information-processing primitives, like non-signalling between distant agents. Here, we propose exploring the opposite direction: to take agents as the basic building blocks through which we test a physical theory, and recover operational notions of locality from signalling conditions. First, we introduce an operational model for the effective state spaces of individual agents, as well as the range of their actions. We then formulate natural secrecy conditions between agents and identify the aspects of locality

Abstract:

Application of MXene materials in perovskite solar cells (PSCs) has attracted considerable attention owing to their supreme electrical conductivity, excellent carrier mobility, adjustable surface functional groups, excellent transparency and superior mechanical properties. This article reviews the progress made so far in using Ti3C2Tx MXene materials in the building blocks of perovskite solar cells such as electrodes, hole transport layer (HTL), electron transport layer (ETL) and perovskite photoactive layer. Moreover, we provide an outlook on the exciting opportunities this recently developed

Abstract:

Currently, speed detection of travelling block system is carried out mainly by detection roller speed, which results in a larger error. Against this background, a method to test crown block pulley was put forward, and its rotation speed precision and also its reliability were analyzed. The method is effective in improving detection accuracy and avoiding errors arising from skidding on the basis of applying the principle that rotation speed ratio of different fixed blocks is a constant value, thus judging the occurring of slipping by examining rotation speed for different fixed pulley. This met

Abstract:

Operational flexibility is a powerful but complex strategy that is increasingly used in manufacturing and service industries. We introduce operational flexibility to ship production as a method to alleviate the effects of delays that ultimately create issues such as high cost, high variability in production workload, ineffective production control, and resultant low facility use. Our emphasis is on how incorporating a flexible curved block job shop can, with appropriate control/scheduling, increase the efficiency and timeliness of the block assembly process for both flat and curved blocks and

Abstract:

Seasonal and industrial fluctuations in natural gas demands require optimized gas storage operations, especially in depleted reservoirs, to ensure a stable supply. This study proposes a novel optimization model for injection–production processes using the simulated annealing–particle swarm optimization (SA-PSO) algorithm. The model focuses on minimizing pressure variances across different reservoir blocks during injection–production cycles. The approach is applied to the W23 underground gas storage facility, where a high-precision 3D geological model and numerical simulations were developed. T
