BACKGROUND Data from our previous studies indicate that Taser X26 stun devices can acutely alter cardiac function in swine. We hypothesized that most transcardiac discharge vectors would capture ventricular rhythm, but that other vectors, not traversing the heart, would fail to capture the ventricular rhythm. METHODS Using an Institutional Animal Care and Use Committee (IACUC) approved protoc...

Gastric residual volume (GRV) is considered as an objective parameter for gastric emptying and tolerance of feeding. The effect of infant's position after feeding on gastric residual has been mostly conducted in infants. The aim of this study was to assess the difference between right side and semi recumbent positions after feeding on gastric residual volume among infants. A quasi experimental ...

This paper presents a simplified approach for the design of semi-continuous composite beams in braced frames, where specific attention is given to the effect of joint rotational stiffness. A simple composite beam model is proposed incorporating the effects of semi-rigid end connections and the non-prismatic properties of a 'cracked' steel-concrete beam. This beam model is extended to a sub-fram...

In this paper experimental studies on vibration suppression of a cantilevered ER sandwich beam subjected to periodic disturbances are conducted. The employed controller combines a semi-active controller with an active controller and is thus termed hybrid controller. The semi-active controller is based on fuzzy-like control strategy and the active controller uses a plant disturbance canceler for...

The vision of populating the world with autonomous systems that reduce human labor and improve safety is gradually becoming a reality. Autonomous systems have changed the way space exploration is conducted and are beginning to transform everyday life with a range of household products. In many areas, however, there are considerable barriers to the deployment of fully autonomous systems. We refe...

We have developed a semi-supervised learning method based on the Expectation-Maximization (EM) algorithm, and maximum likelihood and maximum a posteriori classifiers. This scheme utilizes a small set of labeled and a large number of unlabeled training samples. We have conducted several experiments on multispectral images to understand the impact of unlabeled samples on the classification perfor...

Because of many advantages over other control systems, semi-active control devices have received considerable attention for applications to civil infrastructures. A variety of different semi-active control devices have been studied for applications to buildings and bridges subject to strong winds and earthquakes. Recently, a new semi-active control device, referred to as the resetable semi-acti...
