A telescopic cascode opamp typically has a higher frequency capability and consumes less power than other topologies. The disadvantage of a telescopic opamp is severely limited output swing. In a conventional telescopic opamp shown in Figure 1, all transistors are biased in the saturation region. Transistors M1-M2, M7-M8 and the tail current source M9 must have at least Vds,sat to offer a good ...
This paper concerns the application of reduced order modeling techniques to power grid simulation. Swing dynamics is a complex non-linear phenomenon due to which model order reduction of these problems is intricate. A multi point linearization based model reduction technique trajectory piece-wise linearization (TPWL) method is adopted to address the problem of approximating the nonlinear term i...
The Health Care Financing Administration (HCFA) implemented a swing-bed demonstration and evaluation program for rural communities in the 1970's. The demonstration substantiated the cost effectiveness of providing long-term care in small, rural, acute care hospitals. As a result, Section 904 of the Omnibus Reconciliation Act of 1980 (Public Law 96-499) authorized the national swing-bed program,...
A bridge crane is often used in a complex environment and subject to the interference of all loads. Some uncertain factors have an inevitable impact on its swing. So force situation during working cycle analyzed, three-dimensional dynamic mathematical model built. Through simulation analysis under action driving wind load, change law swing angle studied. Then, fuzzy control theory determine par...
For the use of green energy and ubiquitous computing, this study investigates miniature electric generators that are constructed with piezoelectric benders. Electric power is generated by vibratory deformation of piezoelectric benders. Three different designs of piezoelectric generators are created and compared in this study by using mechanics analysis. The result shows that the cantilever desi...
We present a swing motion based information access method for mobile devices in a public space. Recently, various media for public spaces exist, the poster, the signboard advertisement, and the street vision, etc. In InfoRod, the provider prints the swing motion code in those media. The user can access online information related to the media by swinging the mobile device according to the swing ...
This paper presents design and verification of an estimation and control system for a helicopter slung load system. The estimator provides position and velocity estimates of the slung load and is designed to augment existing navigation in autonomous helicopters. Sensor input is provided by a vision system on the helicopter that measures the position of the slung load. The controller is a combin...
The implications of a long-lasting mechanical load on the locomotor activity are poorly understood. The objective of the present studies was to determine an impact of excess body weight on basic spatiotemporal gait measures and to test the hypothesis that leg swing phase may account for a load-related adaptation of the stride characteristics. To this end the basic spatial and temporal stride me...
For most of our history, we predominantly ran barefoot or in minimalist shoes. The advent of modern footwear, however, might have introduced alterations in the motor control of running. The present study investigated shod and barefoot running under the perspective of the modular organization of muscle activation, in order to help addressing the neurophysiological factors underlying human locomo...
During walking, cutaneous reflexes in ankle flexor muscle [tibialis anterior (TA)] evoked by tibial nerve (TIB) stimulation are predominantly facilitatory at early swing phase but reverse to suppression at late swing phase. Although the TIB innervates a large portion of the skin of the foot sole, the extent to which specific foot-sole regions contribute to the reflex reversals during walking re...
