Advances in wireless communication and embedded computing technologies can have significant impacts in structural sensing, monitoring and control. Prior research efforts have demonstrated the benefits of low-cost wireless sensing systems for structural monitoring. This paper discusses the possibilities of extending the functionalities of wireless sensors for structural control applications. By ...

In this paper we study totally projective QTAG-modules and the extensions of bounded QTAG-modules. In the first section we study totally projective modules M/N and M ′/N ′ where N , N ′ are isomorphic nice submodules of M and M ′ respectively. In fact the height preserving isomorphism between nice submodules is extented to the isomorphism from M onto M ′ with the help of Ulm-Kaplansky invariant...

High voltage IGBT modules are widely used in high power applications, such as traction and large drives. These applications demand high reliability modules and power devices with improved electrical characteristics in terms of reduced losses, increased ruggedness and good controllability for an increased temperature range. The previous SPT+ 3.3kV module rated at 1500A offered superior static an...

Three-dimensional integrated circuits (3D ICs) introduce wafer bonding and Through Silicon Vias (TSVs) as new modules, thus extending manufacturing requirements beyond CMOS. A 3D IC with a photosensor is taken as an example to further analyze the resulting new metrology requirements for mass production. For the wafer bond module, data on defects before and after bonding, bond interface adhesion...

Universal Design for Learning (UDL) aims to increase accessibility to learning by extending the concepts of Universal Design (UD). UD arose in the field of architecture and suggests that one can increase the accessibility of an architectural feature if certain considerations are made to the design of that feature prior to its construction. The essence of UDL is to extend accessibility of a lear...

Intelligent tutoring systems (ITSs) provide students with a one-on-one tutor, allowing them to work at their own pace, and helping them to focus on their weaker areas. The RUR– Python Learning Environment (RUR-PLE), a game-like virtual environment to help students learn to program, provides an interface for students to write their own Python code and visualize the code execution (Roberge 2005)....

We extend some recent results on the differentiability of torsion theories. In particular, we generalize the concept of (α, β)-derivation to (α, β)higher derivation and demonstrate that a filter of a hereditary torsion theory that is invariant for α and β is (α, β)-higher derivation invariant. As a consequence, any higher derivation can be extended from a module to its module of quotients. Then...

Let $R$ be a ring, $sigma$ be an endomorphism of $R$ and $M_R$ be a $sigma$-rigid module. A module $M_R$ is called quasi-Baer if the right annihilator of a principal submodule of $R$ is generated by an idempotent. It is shown that an $R$-module $M_R$ is a quasi-Baer module if and only if $M[[x]]$ is a quasi-Baer module over the skew power series ring $R[[x,sigma]]$.

In this paper we study the module contractibility ofBanach algebras and characterize them in terms the conceptssplitting and admissibility of short exact sequences. Also weinvestigate module contractibility of Banach algebras with theconcept of the module diagonal.
