Extensions to Study Electrochemical Interfaces - A Contribution to the Theory of Ions
In the present study an alternative model allows the extension of the Debye-Hückel Theory (DHT) considering time dependence explicitly. From the Electro-Quasistatic approach (EQS) done in earlier studies time dependent potentials are suitable to describe several phenomena especially conducting media as well as the behaviour of charged particles in arbitrary solutions acting as electrolytes. Thi...

A variety of computing technologies, in addition to the personal computer, are now commonly used in many settings. As networking infrastructures mature, it is increasingly feasible and affordable to consider closer integration and use of these heterogeneous devices in tandem. However, little is known about how best to design or evaluate ゲ┌Iエ けdevice ecologiesげき in particular, how best to combin...
متن کاملG-positive and G-repositive solutions to some adjointable operator equations over Hilbert C^{∗}-modules
Some necessary and sufficient conditions are given for the existence of a G-positive (G-repositive) solution to adjointable operator equations $AX=C,AXA^{left( astright) }=C$ and $AXB=C$ over Hilbert $C^{ast}$-modules, respectively. Moreover, the expressions of these general G-positive (G-repositive) solutions are also derived. Some of the findings of this paper extend some known results in the...
متن کاملA Theory of Information Matching ( TIM ) ∗
In this work, we propose a theory for information matching. It is motivated by the observation that retrieval is about the relevance matching between two sets of properties (features), namely, the information need representation and information item representation. However, many probabilistic retrieval models rely on fixing one representation and optimizing the other (e.g. fixing the single inf...
متن کاملA Formal Theory of Configurational Phenomena Tim
At an observational level t it is a commonplace that languages differ from each other in terms of the freedom with which constituents may berearranged within phrases. This has formed the basis of a traditional typological distinction between IIfree-word-order languages such as Sanskrit or Latin and IIfixed-word-order ll languages such as English. The theory of grammar should account for this va...
