Impact force measurement in Shirodhara. [PDF]
J Ayurveda Integr Med, 2019 Shirodhara is an ayurvedic procedure usually administered to alleviate mental stress. The process involves impact on the forehead by a free fall of a continuous stream of temperature controlled fluid.In this study, the impact force generated on the forehead due to fluid falling from dhara pot held at a standard height of 4 angulas is measured passing ...

Confronting interatomic force measurements [PDF]
Review of Scientific Instruments, 2021 The quantitative interatomic force measurements open a new pathway to materials characterization, surface science, and chemistry by elucidating the tip–sample interaction forces. Atomic force microscopy is the ideal platform to gauge interatomic forces between the tip and the sample.

Influence of Noise on Force Measurements [PDF]
Physical Review Letters, 2010 We demonstrate how the ineluctable presence of thermal noise alters the measurement of forces acting on microscopic and nanoscopic objects. We quantify this effect exemplarily for a Brownian particle near a wall subjected to gravitational and electrostatic forces.

Vision-based force measurement [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2004 This paper demonstrates a method to visually measure the force distribution applied to a linearly elastic object using the contour data in an image. The force measurement is accomplished by making use of the result from linear elasticity that the displacement field of the contour of a linearly elastic object is sufficient to completely recover the ...

Measuring mitotic forces [PDF]
, 2018 Productive chromosome movements require that a large multiprotein complex called the kinetochore assemble on sister centromeres. The kinetochore fulfills two critical functions as (1) the physical linkage between chromosomes and spindle microtubules and (2) a mechanomolecular sensor that relays a spindle assembly checkpoint signal delaying anaphase ...

Roughness of Microspheres for Force Measurements [PDF]
Langmuir, 2008 We have investigated the morphology and surface roughness of several commercially available microspheres to determine their suitability for force measurements using the atomic force microscope. The roughness varies considerably, depending on sphere size and material, ranging from nearly ideally flat up to micrometer-sized features.

The kilogram and measurements of mass and force
Journal of Research of the National Institute of Standards and Technology, 2001 This paper describes the facilities, measurement capabilities, and ongoing research activities in the areas of mass and force at the National Institute of Standards and Technology (NIST). The first section of the paper is devoted to mass metrology and starts with a brief historical perspective on the developments that led to the current definition of ...

Nanonet Force Microscopy for Measuring Cell Forces [PDF]
Biophysical Journal, 2016 The influence of physical forces exerted by or felt by cells on cell shape, migration, and cytoskeleton arrangement is now widely acknowledged and hypothesized to occur due to modulation of cellular inside-out forces in response to changes in the external fibrous environment (outside-in).

Design of a Tri-Axial Force Measurement Transducer for Plantar Force Measurements [PDF]
Journal of Dynamic Systems, Measurement, and Control, 2018 Transducers for spatial plantar force measurements have numerous applications in biomechanics, rehabilitation medicine, and gait analysis. In this work, the design of a novel, tri-axial transducer for plantar force measurements was presented. The proposed design could resolve both the normal and the shear forces applied at the foot's sole.
