over the past decade, many applications were intended for filtration by membrane technology especially the thin film composite (tfc) membranes. in advanced developments of thin film membranes, an attempt was made to spread a new generation of membranes called thin film nano composite (tfn) membranes. however, in the last generation of tfns, an ultrathin selective film of nanoparticles is coated...

The simulation of the store separation using the automatic coupling of dynamic equations with flow aerodynamics is addressed. The precision and cost (calculation time) were considered as comparators. The method used in the present research decreased the calculation cost while limiting the solution error within a specific and tolerable interval. The methods applied to model the aerodynamic force...

this field study was conducted on 60 women who working in related centers of universities of medical sciences in tehran. data gathering tool was maternal separation anxiety questionnaire that designated by hock & et al. (1982).  findings revealed that majority of the research units (71.7%), have high degree of maternal separation anxiety. mean degree of maternal separation anxiety was (21.22±3....

â a model is developed for separation of multicomponent gas mixtures in a countercurrent hollow fiber membrane module. while the model’s solution in countercurrent module usually involves in a time consuming iterative procedure, a proper initial guess is proposed for beginning the calculation and a simple procedure is introduced for correcting the guesses, hereby the cpu time is decreased ess...

This paper presents an approach for knowledge-based multimedia presentation generation. The basic idea is the separation of information to be presented, presentation and the context in which presentation generation takes place. The context takes into consideration a wide set of influencing factors. Methods for the basic steps of intelligent multimedia presentation generation (content selection,...

Compared with common airliners, High/Medium Altitude Long Endurance (HALE/MALE) RPAS are lighter and have larger wingspan. Therefore RPAS will be extremely sensitive to vortex interactions with larger airliners, not only during departures and arrivals, but also at medium and high altitudes during the en-route phase. The extent of this sensitivity shall be investigated in order to determine safe...

An HPSG-based grammar and a sentence generation system for small set of Japanese in legal expert domain are constructed. The system adopts its own general semantic system into which a domainspeci c logical form is converted. This separation between domain-speci c semantics and linguistic one gives exibility to both the task processing and the sentence generation. We also propose a visualization...

We have performed laboratory experiments to study wave generation over and in the lee of model topography. We have chosen to use periodic, finite-amplitude hills which are representative of the Earth’s major mountain ranges as well as the repetitious topographic features of the ocean floor. The topographic shapes are selected to encompass varying degrees of roughness, from smoothly-varying sinu...

Based on spectral beam combining we obtain 16 W of output power, combining two 1063 nm DBR-tapered diode lasers. The spectral separation within the combined beam can be used for subsequent sum-frequency generation. OCIS codes: (140.2020) Diode lasers; (140.3298) Laser beam combining; (190.2620) Harmonic generation and mixing

Aspect-oriented framework is a new paradigm that complements the aspect-oriented technology. The premise of aspect-oriented technology is the separation of concerns, where functional components are designed relatively in isolation of the non-functional components in order to avoid the code-tangling phenomena. In this paper we present a formal methodology that supports the aspectual behavioral m...
