A key ingredient in simulation of ow in porous media is accurate determination of the velocities that drive the ow. Large-scale irregularities of the geology (faults, fractures, and layers) suggest the use of irregular grids in simulation. This paper presents a control-volume mixed nite element method that provides a simple, systematic, easily implemented procedure for obtaining accurate veloci...

introduction: acoustic transient cavitation is the primary mechanism of sonochemical reaction and has potential use for tumor treatment. in this study, the in vivo anti-tumor effect of simultaneous dual-frequency ultrasound at low-level intensity (isata < 6 w/cm2) was investigated in a spontaneous murine model of breast adenocarcinoma in balb/c mice. materials and methods: forty tumor bearing m...

In this paper, we discuss the design and testing of a reactive environment for musical performance. Driven by the interpersonal interactions amongst musicians, our system gives users, i.e., several musicians playing together in a band, real-time control over certain aspects of their performance, enabling them to change volume levels dynamically simply by moving around. It differs most notably f...

introduction: low self-esteem in adolescence is one of the risk factors for negative outcomes in important domains of adulthood life. due to the lack of trials based on modern methods of teaching in the field of self-esteem, this study aimed to investigate the effects of a peer-led training program on female second graders’ self-esteem in public secondary schools in shiraz. methods: the present...

There have been many researches on object grasping in cooperating systems assuming no object slippage and stable grasp and the control system is designed to keep the contact force inside the friction cone to prevent the slippage. However undesired slippage can occur due to environmental conditions and many other reasons. In this research, dynamic analysis and control synthesis of a cooperating ...

Lung volume equipment and infection control. J.L. Clausen. ©ERS Journals Ltd 1997. ABSTRACT: As part of the consensus workshop regarding lung volume measurements for the American Thoracic Society and European Respiratory Society, this background paper reviews mechanisms and risks of cross-infection resultant from performing measurements of absolute lung volumes either by body plethysmography, g...

Continuous blood volume monitoring (CBVM) is believed to be a promising method for making the determination of patients' "dry weight" more objective, and ultrafiltration (UF) control more appropriate. Although blood volume response to UF and the interrelation between blood volume changes and changes in hemodynamic parameters are highly individual, certain principles of this response and interre...
