Making waves: The potential of generative AI in water utility operations.

Water utilities facing increasingly complex infrastructure and operations stand to significantly benefit from artificial intelligence (AI). Current research in water distribution systems engineering primarily focuses on Specialized AI, which plays a crucial role in processing extensive datasets, identifying patterns, and extracting actionable insights to improve the resilience and efficiency of water utility operations. However, barriers of usability, accessibility, and trainability hinder broader adoption.

Analytical model for sound of explosives and firearms.

An analytical model is presented for approximate prediction of the waveform and the sound level spectrum of blast waves generated by explosives and firearms. The model is based on numerical results for spherical blast waves, with overpressures between 10 kPa and 100 MPa, and a nonlinear propagation theory for blast waves. The matching of the numerical results and the nonlinear propagation theory is investigated, and compared with results from the literature and results of calculations with a nonlinear propagation model.

Humanising childbirth - Maternity acupressure training for healthcare providers at the Fernandez Foundation Hospitals, Hyderabad, India. Evaluation of program delivery in one region of India.

Background: Internationally, traditional medicine approaches are used to support humanised childbirth practices. Labour support issues in low- and middle-income countries (LMICs), include limited resources, staffing, and escalating pharmaceutical interventions. There is a strong interest in evidence-based acupressure programs, however, training and experience to implement them is limited.

Model calculations and measurements of shooting sound in practical situations.

Shooting sound in practical situations with propagation distances up to 300 m is investigated by means of model calculations and measurements. The results illustrate uncertainties in the model calculations for practical situations. The measurements were performed with various small-caliber weapons.

Noise of underwater explosions in the North Sea. A comparison of experimental data and model predictions.

An analysis is presented of sound measurements performed near two detonations of unexploded ordnance (UXO) in the North Sea, at distances ranging from 1.5 to 12 km. The charge masses of the detonations were 325 and 140 kg TNT equivalent.
