The irradiance of the Sun changes slightly with the solar cycles. In this paper the variation of heliospheric current sheet tilt angle with the total solar irradiance is examined. The average value of the tilt angle, following both the radial and the classic models are considered at length with a view to re-look some interesting features. Intensity of protons and antiprotons in different solar ...

We model the spontaneous elastic shear deformations of smectic elastomers as they make the thermal transition between the A and C phases. Tilt of the director is accompanied by shear. Unlike nematic elastomers where spontaneous elongation is associated with changes in the magnitude of order, spontaneous distortion in smectics is instead shear and is associated with rotation of the director of t...

A subclinical form of slipped capital femoral epiphysis (SCFE) can lead to subtle morphologic abnormalities, such as cam-type femoroacetabular impingement (FAI). Femoroacetabular impingement is a mechanical hip abnormality that typically affects young populations and leads to hip pain and premature osteoarthritis. Imaging is critical to diagnosis, whether by radiograph, magnetic resonance imagi...

Reduced inertial sensor systems (RISS) have been introduced by many researchers as a low-cost, low-complexity sensor assembly that can be integrated with GPS to provide a robust integrated navigation system for land vehicles. In earlier works, the developed error models were simplified based on the assumption that the vehicle is mostly moving on a flat horizontal plane. Another limitation is th...

The optimal power generation from a solar power system for a detailed loading and irradiation scenario prevailing at a specific location in India has been determined. Three different types of loads reflecting economic and residential activity at the location has been considered. Daily global and diffuse solar irradiation data corresponding to two different seasons of the year have been used in ...

[Purpose] The purpose of this study was to determine the effect of ground tilt on the lower extremity muscle activity of stroke patients performing squat exercises. [Subjects] Fifteen hemiparetic patients volunteered to participate in this study. [Methods] The subjects performed squat exercises at three different ground tilt angles: 15° plantar flexion, a neutral position, and 15° dorsiflexion....

Superparamagnetic colloidal particles confined to a flat horizontal air-water interface in an external magnetic field, which is tilted relative to the interface, form anisotropic two-dimensional crystals resulting from their mutual dipole-dipole interactions. Using real-space experiments and harmonic lattice theory we explore the mean-square displacements of the particles in the directions para...

The equation of motion has been obtained from the mass and linear momentum conservation laws and has been expressed in terms of interface local tilt angle. Through the development of the equation have been neglected the contribution from the gravity terms associated to the curvature of the interface but retained those dependent by interface inclination. The analytical solution is presented in t...

[Purpose] This study aimed to develop unilateral exercises for urban drivers and investigate the effect of these exercises on low back pain (LBP). [Subject and Methods] A 40-year-old male driver, who complained of LBP on the left side at L3-5 levels, participated in this study. A two-session program was conducted, and LBP, pelvic tilt angle, and trunk range of motion were measured after each se...

In this paper, we investigate the kinematic mechanism and path planning of a two-caster nonholonomic vehicle (the Essboard) which is a recent variant of skateboards. Different from the most studied Snakeboard, the Essboard consists of a torsion bar and two platforms, each of which contains a pedal and a caster. We study the relationship between the tilt angle of the pedal and the wheel directio...
