For bounded linear operators defined on complex infinite-dimensional Banach space, H. Zariouh, in an article [1] introduced and studied the property (gaz). In this study, through techniques using local spectral theory of operators, we discover sufficient conditions that allow transfer (gaz) from two tensor factors T S to their product T⊗S. The stability under perturbations is also investigated....

Gaz kaynağı operasyonlarında sürecin süresini azaltmak için, kaynak bölgesinde düzgün akışkan özellikleri elde edebilmek için aleve giden gaz akısına doğrudan beslenebilen sıvı akışkanlar kullanılır. Bunların başında da bor türevi sıvılar gelir. Trimetil borat sıvısı kullanımında verimi artırılmakla birlikte iş riski de aynı oranda artırılmaktadır. Basınçlı kaplar prensibine göre çalışan düzene...

Compound real options are combinations of real options, where an exercise of a real option opens another real option. Compound real options are commonly found in a number of industrial projects, but are especially relevant in, e.g., research and development (R&D) where the R&D projects give the real option to research further, or to start the implementation of the results. Valuation of compound...

The aggregate welfare measure for a change in the provision of a public good derived from a contingent valuation (CV) survey will be higher if the same elicited mean willingness to pay (WTP) is added up over individuals rather than households. A trivial fact, however, once respondents are part of multi-person households, it becomes almost impossible to elicit an “uncontaminated” WTP measure tha...

When the stagnation temperature of the combustion chamber or ambient air increases, the specific heats and their ratio do not remain constant any more, and start to vary with this temperature. The gas remains perfect, except, it will be calorically imperfect and thermally perfect. A new generalized form of the Prandtl Meyer function is developed, by adding the effect of variation of this temper...
