Current mode circuits like current conveyors are getting significant attention in current analog ICs design due to their higher band-width, greater linearity, larger dynamic range, simpler circuitry, lower power consumption and less chip area. The second generation current controlled conveyor (CCCII) has the advantage of electronic adjustability over the CCII i.e. in CCCII; adjustment of the X-...

Soft magnetic films with a wide-range tunable ferromagnetic resonance frequency are suitable for miniaturization and multifunctionalization of microwave integrated circuits. Fabrication of these films for high-frequency applications is usually complicated and difficult. We demonstrate a simple method to fabricate patterned FeNi soft magnetic strip films by magnetron sputtering and photolithogra...

NIOSH researchers conducted a study to compare seat designs on underground coal mine haulage vehicles. The objective of the study was to support prior findings that NIOSH-designed seats, which incorporated ergonomic design features (e.g., viscoelastic foam padding and low-back support), are improved designs. Based on measured levels of vehicle jarring/jolting and perceived discomfort, researche...

Nowadays, the research about three-dimensional topology control has focused on ensuring the connectivity of the networks, and has seldom considered the balance between neighbor node degree and energy consumption minimum path. In order to solve this problem, this paper proposes an adjustable topology control algorithm in three-dimensional wireless sensor networks, and this algorithm can dynamica...

Metal organic frameworks (MOFs) is a research hotspot in the solar fuel production and photo-degradation of pollutants field due to high surface area, rich metal/organic species, large pore volume, adjustability structures compositions. Therefore, this review, we first summarized design factors photocatalytic materials based on MOF from perspective “star” MOF. The modification strategies MOFs-b...

Sukhan Leey;x Chunsik Yix Jet Propulsion Laboratoryy Dept. of Computer Sciencex California Institute of Technology University of Southern California Pasadena, CA 91109 Los Angeles, CA 90089-0781 Abstract The assemblability, which is the probability of successfully assembling the product parts, is directly related to the product cost. Especially, we consider the assembly failures due to toleranc...

LTE broadcast is a communication standard which is expected to revolutionize the multimedia service provision in the future. The distinctive features of this standard such as increased service capacity, high spectral efficiency, and spectral adjustability have encouraged many companies to select this standard for the future generation broadcasting. In this paper, after a complete introduction o...

In this paper, we investigate the task-space consensus problem for multiple robotic systems with both the uncertain kinematics and dynamics in the case of existence of constant communication delays. We propose an observer-based adaptive controller to achieve the manipulable consensus without relying on the measurement of task-space velocities, and also formalize the concept of manipulability to...

Sling therapy is the enhanced surgical support of the urethra. In this article, the history of the use of slings for the surgical treatment of female urinary stress incontinence is reviewed, and the usual surgical routes for retropubic (transvaginal) or transobturator tape passage are described. The latest innovation in sling therapy is the use of minislings, which are short tape mesh implants ...
