Complex contact interactions between the robot and its environment (contact between a dextrous hand and a grasped object, contact between an all-terrain vehicle and the terrain, ..) depend on physical properties such as mass, mass distribution, rigidity/elasticity factors, viscosity, and collision forces. Classical geometrical models (representing the spatial properties of an object) are obviou...

Previously the investigation of employee harassment within the workplace would typically have involved obtaining evidence regarding physical contact, verbal contact (face to face or via telephone) or written contact (via letters or notes or email) between a suspect and a victim. Social media has added a new avenue to the investigation of employee harassment that goes beyond the physical workpla...

Urbanization, resource exploitation, and lifestyle changes have diminished possibilities for human contact with nature in urbanized societies. Concern about the loss has helped motivate research on the health benefits of contact with nature. Reviewing that research here, we focus on nature as represented by aspects of the physical environment relevant to planning, design, and policy measures th...

The aim of this study was to examine how to support breastfeeding of preterm infants immediately after birth in the delivery ward, during their hospital stay in a neonatal intensive care unit (NICU), and at home after hospital discharge. Specifically, the role of early physical contact, maternal breastfeeding attitude, and an internet-based peer support group were investigated. The delivery war...

The purpose of this study was the investigation of the removal of phenol with nanoparticles zero valent iron and iron powder. The effect of various parameters such as initial concentration, pH, contact time, and dosage of NZVI and Fe powder was examined, and a Central Composite Design (CCD) was then applied to appraisal the effect of these variables. The chemical and physical characteristic...

Full counting statistics of electron transport is of fundamental importance for a deeper understanding of the underlying physical processes in quantum transport in nanoscale devices. The backaction effect from a detector on the nanoscale devices is also essential due to its inevitable presence in experiments. Here we investigate the backaction of a charge detector in the form of a quantum point...

I try to present a small view of the properties and issues related to astronomical interferometry observations. I recall a bit of history of the technique, give some basic assessments to the principle of interferometry, and finally, describe physical processes and limitations that affect optical long baseline interferometry and which are, in general, very useful for everyday work. Therefore, th...

Despite the obvious relevance of tactile sensing to robot manipulation, no comprehensive theory exists regarding how to use this information to estimate hand-object state. This paper explores this issue in the context of particle filtering. The paper proposes using measurements of contact positions and velocities for the purposes of estimating the shape and pose of an object held by the robot. ...
