Feature pyramid of bi-directional stepped concatenation for small object detection
Multimedia Tools and Applications, 2021In recent years, great breakthroughs have been made in object detection. However, performance of the most algorithms declines significantly when detecting small objects in an image. Thus, multi-scale feature maps are often used to develop network variants to generate multi-scale representations.

Effective vibrating barriers design for the Zoser pyramid using artificial neural network [PDF]
Soil Dynamics and Earthquake EngineeringVibrating Barrier (ViBa) is a non-invasive strategy used to protect buildings, especially ancient and historic structures, from seismic wave vibrations. The ViBa is a spring-mass device installed at a separate location beneath the ground surrounding the ...

Transient magnetorheological response of magnetoactive elastomers to step and pyramid excitations
Soft Matter, 2016Transient rheological response of magnetoactive elastomers is experimentally studied using dynamic torsion at a fixed oscillation frequency in temporally stepwise changing magnetic fields and oscillation amplitudes. For step magnetic-field excitations, at least three exponential functions are required to reasonably describe the time behavior of the ...

Performance evaluation of stepped multiple basin pyramid solar still
Materials Today: Proceedings, 2021Abstract In this work an attempt has been carried out to design and construct a novel stepped multiple basins in pyramid solar desalination system. Four basins have been incorporated in the pyramid solar still in which the area of each basin varies gradually towards the condensing glass surface.

The Geometry of Zoser's Step Pyramid at Saqqara
Journal of the Society of Architectural Historians, 1986The Step Pyramid of Zoser at Saqqara is examined from the point of view of constructive geometry and mensuration. The evidence is that it is based on geometric proportion, though this may simply be the outcome of peg-and-chord technology employed in setting out the monument. The procedure that the architect may have followed in setting out the monument

The 3-Step Pyramid Insole Treatment Concept for Idiopathic Toe Walking
Foot & Ankle Specialist, 2016The idiopathic toe walking (ITW) gait pattern is characterized in children for walking since the beginning on their first steps on the forefoot; however, these children are able to support their whole foot on the ground. ITW can only be diagnosed in the absence of any orthopaedic or neurological condition known to cause tiptoe walking.

Repetition Pitch glide from the step pyramid at Chichen Itza
The Journal of the Acoustical Society of America, 2006Standing at the foot of the Mayan step pyramid at Chichen Itza in Mexico, one can produce a pitchy “chirp” echo by handclapping. As exposed by Declercq et al. [J. Acoust. Soc. Am. 116, 3328–3335 (2004)], an acoustic model based on optical Bragg diffraction at a periodic structure cannot explain satisfactorily the chirp-echo sonogram.

One-step synthesis of TOP capped PbSe pyramidal nanocrystals
Materials Chemistry and Physics, 2006Nano layers of PbSe have been fabricated in liquid medium via direct reaction of lead acetate and n-trioctylphosphine bonded selenium. The effect of temperature on particles diameter is studied. The scanning electron microscopy reveals that the layer-by-layer deposition has taken place with average diameter of the particle of about

Impaired step-tracking control in patients with cerebellar and pyramidal lesions
Neurophysiology, 1988Kinematic and electromyographic characteristics of step-tracking movements performed with and without visual guidance were investigated in patients with prevalently intermediary and lateral cerebellar and pyramidal tract lesions. Parameters of the phasic programmed component of motion were shown to be little affected by damage to the intermediary ...
