The paper considers the task of monitoring psychophysiological stress under conditions close to real life, using a wrist-mounted wearable device and a reproducible machine-learning pipeline. An experimental protocol with three classes of states — rest, induced psychosocial stress and standardized physical activity — implemented on a sample of 12 subjects is proposed. The multimodal device registers PPG/HRV, EDA/GSR, skin temperature, and IMU signals. The data is segmented into 60-s windows in 15-s increments, and preprocessing and feature extraction are performed. An ML pipeline has been b

The study develops a Web-GIS prototype for digital environmental passportization of launch-vehicle stage drop zones with built-in veri-fication, traceability, and risk-based prioritization. The platform uses Django 5.0 with PostgreSQL/PostGIS and supports GeoJSON and WMS/WFS; the core entities are Zone, District, Incident, and Pass-port, supplemented by an AuditLog and RBAC. Passporting is im-plemented via Smart Forms with rules for completeness, unit con-sistency, and coordinate accuracy, plus Data Quality/Quality Gate checks (georeferencing, missing values/anomalies, source reliability, ver

Conducting research studies in the agricultural sector to develop technological processes for mechanized cotton harvesting, as well as designing and testing components of cotton harvesting machines, is an urgent task. Although new methods have been developed to evaluate the technological process of mechanized cotton harvesting, in-depth theoretical research on modeling the interaction between the spindle and the cotton plant has not been thoroughly studied. Additionally, methods for calculating the deformation of the doffer brushes during their interaction with the spindle surface when raw cot

This study investigates the effect of transformational leadership on teacher performance, with organizational culture and organizational commitment serving as mediating variables. A quantitative survey was conducted among 128 junior high school teachers in East Java, Indonesia. Structural equation modeling based on partial least squares (SEM-PLS) was employed to examine both direct and indirect relationships among the constructs. The results indicate that transformational leadership has a positive and statistically significant effect on teacher performance. In addition, organizational culture

This study examines the implementation of Financial Services Alternative Dispute Resolution through the Financial Services Sector Dispute Resolution Institution (LAPS SJK) in resolving general insurance disputes under Indonesian Financial Authority Regulation (POJK) No. 61/POJK.07/2020. The purpose of this research is to analyze the legal framework, effectiveness, and challenges of LAPS SJK as a mandatory dispute resolution mechanism in the financial services sector, particularly in general insurance disputes. This research employs a normative juridical method with a statutory, conceptual, and
