Some considerable damage to steel structures during the Hyogo-ken Nanbu Earthquake occurred. Among them, many exposed-type column bases failed in several consistent patterns, such as brittle base plate fracture, excessive bolt elongation, unexpected early bolt failure, and inferior construction work, etc. The lessons from these phenomena led to the need for improved understanding of column base...

As mobile learning simultaneously employs both handheld computers and mobile telephones and other  devices  that  draw  on  the  same  set  of  functionalities,  it  throws  open  the  door  for  swift connection between learners  and teachers. This  study examined and articulated the impact of  the application of mobile devices for teaching English vocabulary items to 123 Iranian semi-illitera...

The aim of this work was to define reliable markers of muscle and processing time in dry-cured ham using a rapid, precise semi quantitative method for the protein fraction soluble in low ionic strength buffer. For this purpose protein labchip Agilent was used to separate proteins and peptides and accurately determine their molecular weights and concentrations electrophoretically. In this way th...

In this paper we discuss curvature tensors in the context of Absolute Parallelism geometry. Different curvature tensors are expressed in a compact form in terms of the torsion tensor of the canonical connection. Using the Bianchi identities some other identities are derived from the expressions obtained. These identities, in turn, are used to reveal some of the properties satisfied by an intrig...

The geometric constructions are performed on (semi) Riemannian manifolds and vector bundles provided with nonintegrable distributions defining nonlinear connection structures induced canonically by metric tensors. Such spaces are called nonholonomic manifolds and described by two equivalent linear connections also induced unique forms by a metric tensor (the Levi Civita and the canonical distin...

In this paper we explore the connection between semi-classical and quantum Birkhoff canonical forms (BCF) for Schrödinger operators. In particular we give a ”non-symbolic” operator theoretic derivation of the quantum Birkhoff canonical form and provide an explicit recipe for expressing the quantum BCF in terms of the semi-classical BCF.

The inference rule semi-resolution is introduced and shown to be complete for ground CNF formulas. It can be employed in a connection-graph setting, and preservation of the spanning property is shown to hold when activated links are deleted. Potential advantages from the employment of semi-resolution as the inference engine in prime implicate computations are brieey discussed .

A mathematically rigorous realization of Feynman integrals is given. The construction works for quadratic actions (there is only a restriction to certain time intervals). These techniques enable the calculation of the semi-classical approximation for a given Feynman prop-agator. Finally, delta sequences in Gaussian analysis are presented and their connection to semi-classical approximation is d...

Ever since the introduction of fuzzy sets by L. A. Zadeh [14], the fuzzy concept has invaded almost all branches of Mathematics. The concept of fuzzy topological space was introduced and developed by C.L. Chang [3] and since then many fuzzy topologists [1,6-13] have extended various notions in classical topology to fuzzy topological spaces. The concept of somewhat continuous functions was intro...
