Gait Analysis of Pak Biawak: A Necrobot Lizard Built using the Skeleton of an Asian Water Monitor (Varanus Salvator)

Advanced Robotics Research, EarlyView.
Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

Interference in Internal Involute Spur Gears

Transactions of the Japan Society of Mechanical Engineers, 1955
This paper deals with the interference in internal involute spur gears and shows, giving the pressure angle α and the addendum (for module) ρ1, ρ2, that the minimum tooth difference to avoid the trochoidal interference is nearly equal to (ρ1+ρ2)cosec2δ and that of avoiding the trimming is nearly equal to 2 (ρ1+ρ2)cosec2δ where (2δ-sin 2δ)/2sin2δ=tanα ...

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

Sustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

Study of the tooth contact for high contact ratio spur gears with long tip relief [PDF]

MATEC Web of Conferences, 2019
Profile modifications are commonly used to avoid shocks between meshing gear teeth produced by the delay of the driven gear, and the subsequent sooner start of contact, due to the teeth deflections.

Relationship Between Micro‐Level Circular Economy and Sustainable Performance in the Metalworking Industry

Sustainable Development, EarlyView.
ABSTRACT The large multinational metalworking industry has increasingly adopted micro‐level circular economy (MLCE) practices; however, the extent to which these initiatives translate into sustainable performance remains insufficiently understood. This study examines the relationship between MLCE and economic, environmental, and social performance ...
