Rock masses are naturally affected by discontinuities, joints and fractures that affect their exploitation. After block extraction, different cutting pattern can produce different recovery ratio of the block. The optimization of the cutting pattern can be computed if the discontinuities are mapped by the use of non-destructive methods. We propose a software code able to compute the number of intersected slabs by different cuttings scenarios. The algorithm adopts a brute force computation of several scenarios as specified by the user. The software uses the Open MP library in order to reduce computation time.

tsCaptum is a Python library that enables explainability for time series classification and regression using saliency maps (i.e., attribution-based explanation). It bridges the gap between popular time series frameworks (e.g., aeon, sktime, sklearn) and explanation libraries like Captum. tsCaptum tackles the computational complexity of explaining long time series by employing chunking techniques, significantly reducing the number of model evaluations required. This allows users to easily apply Captum explainers to any univariate or multivariate time series model or pipeline built using the aforementioned frameworks. tsCaptum is readily available on pypi.org and can be installed with a simple ”pip install tsCaptum” command.
tsCaptum 是一个 Python 库,可使用显著性图(即基于归因的解释)实现时间序列分类和回归的可解释性。它在流行的时间序列框架(如 aeon、sktime、sklearn)和 Captum 等解释库之间架起了一座桥梁。tsCaptum 采用分块技术解决了解释长时间序列的计算复杂性问题,大大减少了所需的模型评估次数。这使得用户可以轻松地将 Captum 解释器应用到任何单变量或多变量时间序列模型或使用上述框架构建的管道中。tsCaptum 可在 pypi.org 上轻松获取,只需使用简单的 "pip install tsCaptum "命令即可安装。

SmartSAT is a mobile web application designed to enhance the efficiency and equitable access of San Antonio’s public transit services, providing real-time bus arrival predictions, notifying riders of seat availability, and gathering rider’s feedback. It aims to leverage technology to deliver an inclusive service with potential impacts for social equality, and enhancement of overall ridership experience. Two studies were conducted to access the impact of SmartSAT on the actual bus arrival times and rider’s communte experience. The findings of the arrival times analysis indicated that certain routes exhibited very slow average differences between their actual and schedule arrival times while a couple displayed a big average difference showing significant delayes and deviations from the schedules timetable. The rider experience study found that there is a differential in the feelings of access to the city’s public transit system held by poor, working-class, and Latinx communities in San Antonio. These findings suggest the need for regular minitoring and optimazation of the bus schedules to improve the effieiency and inclusive access to the current transportaiton system. The outcomes of the study primarily benefit San Antonio residents, especially for underserved communities, leading to an enhancement of its transit network infrastructure.
SmartSAT 是一款移动网络应用程序,旨在提高圣安东尼奥公共交通服务的效率和公平性,提供公交车实时到站预测,通知乘客座位空余情况,并收集乘客的反馈意见。其目的是利用技术提供具有包容性的服务,从而对社会平等产生潜在影响,并改善乘客的整体乘车体验。我们进行了两项研究,以了解 SmartSAT 对巴士实际到达时间和乘客公共体验的影响。到站时间分析结果表明,某些线路的实际到站时间与计划到站时间的平均差异非常小,而有几条线路的平均差异很大,显示出明显的延误和偏离计划时间表的情况。乘客体验研究发现,圣安东尼奥的穷人、工薪阶层和拉丁裔社区对城市公共交通系统的使用感受存在差异。这些发现表明,有必要对公交车时刻表进行定期监测和优化,以提高现有交通系统的效率和包容性。研究结果主要惠及圣安东尼奥居民,尤其是服务不足的社区,从而改善其公交网络基础设施。

Multi-level capacitated lot-sizing problems with linked lot sizes and backorders (MLCLSP-L-B) are used in pharmaceutical tablets manufacturing processes to right-size material production lots so that costs are kept at a minimum, production resource capacities are not exceeded, and customer demand is fulfilled. Uncertain demand behavior characterizes today’s global tablets market. Pharmaceutical companies request solution approaches that solve the MLCLSP-L-B with probabilistic demand. Implementing this model in industrial applications for tablets manufacturing systems requires efficient data processing due to the amount of data and the capability to store simulated demand scenarios. This paper covers the first integration of the MLCLSP-L-B with probabilistic demand and Relational Database Structures (RDS). Modeling techniques for the RDS to process massive data are outlined. A virtual environment provides the implementation software PostgreSQL and infrastructure environment. Additionally, numerical experiments with research data are used to evaluate the agility and efficiency of the developed RDS.
