Physical-statistical analysis of land mobile-satellitechannel
Electronics Letters, 1998 The authors describe a time-series propagation model in mobile-satellite channels which considers 3D path profiles. Based on the Fresnel-Kirchhoff theory, the prediction is produced by considering statistical distributions for the building profile, leading to time-series which have both first- and second-order statistics similar to real outdoor ...

Diurnal Dust Devil Behaviour for the Viking 1 Landing Site: Sols 1 to 30 [PDF]
, 2004 Previous martian studies have provided an understanding of diurnal dust devil behaviour for Viking 2 and the Mars Pathfinder landing sites. It is the purpose of this work to complete this analysis by analysing the meteorological data from the Viking 1 ...

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.

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion
Advanced Robotics Research, EarlyView.A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

Exploitation dynamics of fish stocks
, 2006 I address the question of the fluctuations in fishery landings. Using the fishery statistics time-series collected by the Food and Agriculture Organization of the United Nations since the early 1950s, I here analyze fishing activities and find two ...

Sialic Acid Sensing via Molecularly Imprinted Polymer on Laser‐Induced Graphene
Advanced Sensor Research, EarlyView.Sialic acid is an important biomarker for oral and overall health. Salivary levels of sialic acid are linked with oral cancer and other diseases. We develop a point‐of‐care sensor for sialic acid, based on molecularly imprinted aminophenylboronic acid electropolymerized onto laser‐induced graphene.

Documentation of landslides and inaccessible parts of a mine using an unmanned uav system and methods of digital terrestrial photogrammetry [PDF]
, 2015 Quite a big boom has recently been experienced in the technology of unmanned aerial vehicles (UAV). In conjunction with dense matching system, it gives one a powerful tool for the creation of digital terrain models and orthophotomaps.
