An apparatus for direct fugacity measurements on mixtures containing hydrogen

global results on some nonlinear partial differential equations for direct and inverse problems

در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...

Method and an Apparatus for Hydrogen Production from Water

Model Apparatus for Quantum Measurements

We present a model system that behaves as a measurement apparatus for quantum systems should. The device is macroscopic, it interacts with the microscopic system to be measured, and the results of that interaction affect the macroscopic device in a macroscopic, irreversible way. Everything is treated quantum mechanically: the apparatus is defined in terms of its (many) coordinates, the Hamilton...

An Apparatus for Pressure Measurements of Spreading Substances

Results of measurements of the spreading of proteins have been reported in the previous article. The measurements were made with an apparatus differing in various ways from existing apparatus (Langmuir, Marcelin, and Adam). I t was essential in the construction of this apparatus to obtain an instrument by which it would be possible to make quick and accurate measurements. ~ Also we tried to mak...

Apparatus for Neutron Scattering Measurements on Sheared Fluids

We report on the construction of an apparatus to allow neutron scattering measurements on fluids undergoing shear. The apparatus has been used with the cold neutron small-angle-neutron-scattering (SANS) spectrometer at the NIST research reactor and will be made available to users as a permanent part of the NIST facility.
