This contribution deals with a mixed variational formulation of 3D contact problems with the simplest model involving friction. This formulation is based on a dualization of the set of admissible displacements and the regularization of the non-differentiable term. Displacements are approximated by piecewise linear elements while the respective dual variables by piecewise constant functions on a...

The measurement of spherical surface radii exceeding few meters presents a challenge, because the familiar radius-bench method requires large part displacements. Dual-focus zone plates can extend the radius-bench method to measurements of large radii. OCIS codes: (220.4840) Testing, (050.1965) Diffractive lenses

Introduction: Parkinson Disease (PD) is a degenerative and progressive disorder of the central nervous system. It results from degeneration of Substantia Nigra pars compacta (SNc) of the Basal Ganglia (BG). Gait disturbances in PD patients generally get worse over time. The underlying mechanism of gait disturbances in PD has not been elucidated yet. Methods: In this study, we tried to analyze ...

رسوبات کرتاسه بالایی در پهنه ایران زمین در حوضه های متفاوت، با توجه به شرایط حاکم در زمان تشکیل، ظاهراً یکنواخت نبوده است. در نتیجه، واحدهای سنگ چینه ای رسوبات کرتاسه بالایی ایران، به استثناء زاگرس و کپه داغ نامگذاری نشده یا دارای نام های محلی هستند. جهت مطالعه رسوبات کرتاسه بالایی در البرز شمالی برشی در حوالی منطقه پل زغال انتخاب گردید. برش انتخاب شده، در 21 کیلومتری جنوب چالوس به صورت ترانشه آ...

Fuel combinations with substantial differences in reactivity, such as diesel/CNG, represent one of the most promising alternative combustion strategies these days. In general, conversion from diesel to dual-fuel operation can be performed existing in-use heavy-duty compression-ignition engines minimum modifications, which guarantee very little particles, less nitrogen oxide (NOx), and reduced n...

in this note we consider the notion of intuitionistic fuzzy (weak) dual hyper k-ideals and obtain related results. then we classify this notion according to level sets. after that we determine the relationships between intuitionistic fuzzy (weak) dual hyper k-ideals and intuitionistic fuzzy (weak) hyper k-ideals. finally, we define the notion of the product of two intuitionistic fuzzy (weak) du...

Maintaining human body temperature is one of the most basic needs for living, which often consumes a huge amount of energy to keep the ambient temperature constant. To expand the ambient temperature range while maintaining human thermal comfort, the concept of personal thermal management has been recently demonstrated in heating and cooling textiles separately through human body infrared radiat...
