INTRODUCTION The radioactive isotopes of ruthenium with mass numbers 103 and 106 are common fission products and may represent a radiological hazard for the population in case of their release into the environment and transfer to the food chain. Ru, having a half-life of 39.26 d, decays by β emission onto Rh. Ru (T1/2=374 d) is a pure β emitter, and its daughter nuclide, Rh, is radioactive as w...

In this paper deals with the combined effect of thermal radiation and heat source on the MHD free convection heat and mass transfer flow of a viscous incompressible fluid past a uniformly vertical porous plate. The velocity, temperature and concentration field are obtained and discussed graphically for various values of the physical parameters present. In addition, expressions for the skin fric...

This document proposes a new header for use with the SIP call control architecture. The Replaces header is used in peer-to-peer call control to logically replace an existing SIP dialog with a new SIP dialog. This primitive can be used to enable a variety of features, for example: "Attended Transfer" and "Retrieve from Call Park". Note that definition of these example features is non-normative. ...

detected in ten of the fourteen patients, and BAO and MAO were significantly higher than in controls and comparable with acid output in patients with duodenal ulcer (table). These results suggest that increased gastric acid output could be a feature of absorptive hypercalciuria. If ionisation of dietary calcium is a prerequisite for calcium absorption, gastric acid hypersecretion might help to ...

Several industrial processes have the “dead-time effect ” produced due to measurement delay or due to the approximation of higher order dynamics of the process by a simple transfer function model. This delay causes the unstabilty of the whole system. In this paper the designing of Fuzzy controller is done for the system having higher order and high dead time. Performance table shows the affects...

We present observational user study findings of UbiTable, a multi-user interactive table top that provides walk-up wireless connections for multiple personal devices. UbiTable offers shared interactions that allow writing, annotating, drawing, copying, and the transferring of content amoung the tabletop and associated user devices. Out findings uncovered general design considerations and tradeo...

This document analyses the security of the BGP/MPLS IP virtual private network (VPN) architecture that is described in RFC 4364, for the benefit of service providers and VPN users. The analysis shows that BGP/MPLS IP VPN networks can be as secure as traditional layer-2 VPN services using Asynchronous Transfer Mode (ATM) or Frame Relay. Behringer Informational [Page 1] RFC 4381 Security of BGP/M...

This paper addresses a control system design for a table drive system based on the disturbance observer (DOB)-based predictive functional critical control (PFCC). To empower the previously developed DOB-based PFC to handle constraints on controlled outputs, we propose to take a critical control approach. To this end, we derive the transfer function representation of the PFC controller and yield...

the purpose of the present study was to investigate the effect of variability of attentional focus distance by self-talk on the learning of table tennis forehand in. after pretest, the participants performed 180 forehand strokes during 6 sessions with repeating the words “slightly rotation” in the internal focus group “slightly open” in the near external focus group, “over the net ” in the far ...
