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...
Interoperable Coordinate Transformation and Identification of Coordinate Systems
The OpenGIS Consortium (OGC), an industry group, has developed COM, CORBA and Java interface specifications allowing vendors to develop mutually interoperable geospatial software. OGC established the Coordinate Transformation Working Group (CT-WG) in April 1998. The working group developed a Unified Modeling Language object model of coordinate systems (CS) and coordinate transformations (CT) in...
متن کاملBilingual Memory Storage: Compound-Coordinate and Derivatives
A recurring theoretical issue in the study of bilingualism concerns the manner in which speakers of one or more languages might store their languages in memory. Figure 1 shows a plausible semantic network organization for the Spanish-English interlingual homograph red. Interlingual homographs are words across languages that are similar in form, but different in meaning (Degani and Tokowicz 2010...
متن کاملReducing Retrieval Time in Automated Storage and Retrieval System with a Gravitational Conveyor Based on Multi-Agent Systems
The main objective of this study is to reduce the retrieval time of a list of products by choosing the best combination of storage and retrieval rules at any time. This is why we start by implementing some storage rules in an Automated Storage/Retrieval System (Automated Storage and Retrieval System: AS/RS) fitted with a gravity conveyor while some of these rules are dedicated to storage and ot...
متن کاملCoordinate Systems and Terrain Reusability
This paper is about a coordinate system problem for the “live” aspect of LVC training that impacts terrain reusability. Commonly used commercial software for producing correlated terrains has an outdated definition of datums that assumes that NAD83 and WGS84 are still equivalent, and does not take into account the newer realizations of these, or the fact that there have been significant plate t...
متن کاملMultipole structure and coordinate systems
Multipole expansions depend on the coordinate system, so that coefficients of multipole moments can be set equal to zero by an appropriate choice of coordinates. Therefore, it is meaningless to say that a physical system has a nonvanishing quadrupole moment, say, without specifying which coordinate system is used. (Except if this moment is the lowest non-vanishing one.) This result is demonstra...
