Noise and Vibration Analysis of a Tri‐Lobe Compressor for Industry Application: A Finite Element and Campbell Diagram Approach

Engineering Reports, Volume 8, Issue 8, August 2026.
Finite element and Campbell analyses evaluated noise and vibration in a tri‐lobe compressor. A critical speed of 243 rad/s due to backward whirl was identified. Modal and static results revealed vibration hotspots at flanges and lobe tips. Design optimization enhances structural integrity, reduces resonance risk, and minimizes noise emission.

Behaviour Identification in Farmed Red Deer (Cervus elaphus) Using Wearable Activity Collars

New Zealand Journal of Agricultural Research, Volume 69, Issue 4, August 2026.
Wearable sensors such as accelerometers have shown promise in identifying a range of behaviours in ruminant livestock for welfare and production purposes. The research and production of wearables have primarily focused on delivering to the dairy and beef cattle industries.

High prevalence of muscle stability deficits in semi‐professional football players—Adaptive Force assessment reveals selective impairment of holding capacity with preserved maximal strength: A cross‐sectional study

Knee Surgery, Sports Traumatology, Arthroscopy, Volume 34, Issue 8, Page 2987-3001, August 2026.
Abstract Purpose Despite considerable research, strength screening has shown limited value for injury prediction. The concept of muscle stability assessed by Adaptive Force (AF) offers a distinct perspective—addressing neuromuscular holding capacity closer to injury‐prone motions rather than pushing strength.

Static and Dynamic Analysis of Porous Gas Bearings Lubricated With Air, Refrigerant R‐134a, Helium and Hydrogen

Lubrication Science, Volume 38, Issue 5, Page 301-326, August 2026.
ABSTRACT Porous gas bearings (PGBs) enable high‐speed, oil‐free operation in modern rotating machinery. This study develops a coupled thermo‐hydrodynamic (THD) model for a cylindrical porous gas bearing lubricated with four working fluids—air, R‐134a, helium and hydrogen.

Mandibular Movement Monitoring in Children With Neurodisability

Pediatric Pulmonology, Volume 61, Issue 8, August 2026.
ABSTRACT Background Obstructive sleep apnoea (OSA) in children is diagnosed using polysomnography (PSG), but children with neurodisability are >3 times more likely to not tolerate leads and sensors. The diagnostic accuracy of Sunrise, a small sensor applied to the chin, has not been assessed in this special population.

Control System for the Navigation of the Agricultural Robots: A Review

Journal of Field Robotics, Volume 43, Issue 5, Page 3474-3505, August 2026.
ABSTRACT Control systems for the navigation of autonomous agricultural robots—particularly those operating in uneven terrain and in the presence of static or dynamic obstacles—have advanced considerably in recent years. As conventional machinery evolves toward increasingly automated systems, the design of reliable navigation controllers has become ...
