Higher-order fractional filters with fully controllable frequency characteristics are realized in this work, after fitting the filter’s magnitude response data using a minimum-phase state-space model. Subsequently, rational integer-order transfer functions derived and implemented as active elements: a) Operational Transconductance Amplifiers (OTAs) b) Field Programmable Analog Array (FPAA) devi...

BACKGROUND Numerous techniques have been used to rejuvenate the aging midface. The Endotine midface technique involves an endoscopic temporal approach, including midface dissection and malar suspension with fixation. The Endotine device (Microaire, Charlottesville, Virginia) eliminates the intraoral incision and use of sutures, enabling multipoint fixation and fast, simple adjustability for opt...

The flexible production of solid wood custom furniture is needed to meet the individual needs market. Based on M Company, this study developed a digital design platform and its key technologies (data extraction integration, part family division, coding technology, model base construction, information interaction, connection) proposed multi-attribute overlapping clustering technology (MOCT) meth...

Magnetic field is one efficient approach to realize non-contact control of materials. Here, we propose a type membrane-based metasurface consisting several parts magnetorheological films embedded with magnetic particles, which enable sound insulation through field. The abundant degree freedoms in membrane-type metamaterials are explored by considering composite structures. Through numerical cal...

* Corresponding author ABSTRACT Achieving the dimensional integrity for a complex structural assembly is a demanding task due to the manufacturing variations of parts and the tolerance relationship between them. While assigning tight tolerances to all parts would solve the problem, an economical solution is taking advantage of small motions that joints allow, such that critical dimensions are a...

Achieving the dimensional integrity for a complex structural assembly is a demanding task due to the manufacturing variations of parts and the tolerance relationship between them. Although assigning tight tolerances to all parts would solve the problem, an economical solution is taking advantage of small motions that joints allow, such that critical dimensions are adjusted during assembly proce...

We describe a sampling technique particularly suitable for active vision: Dimensionally-Independent Exponential Mapping (DIEM), in which each dimension of the original data is sampled in an exponentially increasing or decreasing series of steps, with bilateral symmetry about the data mid-point. Multidimensional data sampling is achieved by combining single dimension sampling coordinates. DIEM i...

An ergonomics assessment was conducted in a modern, automated hospital-based laundry to investigate workers' complaints of musculoskeletal aches and pains and general fatigue. Numerous job stressors were identified requiring ergonomic solutions, including prolonged standing, excessive manual handling of transport units, non-adjustability of workstations, work pacing, awkward postures, lack of j...
