Mechanically driven spin-orbit-active weak links
No full textWe show that new functionality of spin-orbit-active electronic weak links can be achieved by their time- dependent mechanical deformation. As an illustration we use a simple model to calculate the electronic spin cur- rent generated by rotating a bent spin-orbit-active nanowire coupled to bulk metallic leads. © M. Jonson, R.I.

A relational algebraic framework for VHDL models management
No full textVery High-Speed Integrated Circuit Hardware Description Language (VHDL) has been used as a design automation tool in all phases of modern very large-scale integrated ( VLSI) design. However; complex relationships between components of real-world systems make the VHDL modeling problem very difficult. Such difficulty can be alleviated by employing some kind of computer-based frameworks with sound formalisms. This paper proposes a new framework for relational algebraic VHDL models management. Its conceptual bases are the system entity structure and the relational algebra formalism. The framework supports automation of the well known planning-generation-evaluation paradigm for VHDL models management. Within the framework, a family of hierarchical structures of a system is organized in the form of VHDL model structure. A candidate model structure which meets design objectives is first selected from the family. Then the VHDL model for the structure is systematically constructed by combining primitive VHDL models in a VHDL library. Designers can conduct appropriate experiments oil the VHDL model for design verification and performance measure. The framework has been implemented on a relational database management system. Experiments of a simplified CPU design show that the framework could be useful for VHDL models management

No full textThis study described syntactic structure on fairy-tale collection of Gadis Korek Api by H.C. Andersen. The study which seen from syntactic structure is sentence pattern based on function category, category, and syntactic role. This study aimed to describe syntactic structure on fairy-tale collection of Gadis Korek Api by H.C. Andersen and it’s distribution towardh Indonesian language. This research used qualitative method and note method was employed for collecting the data. In analysing the data, the researcher used Agih method by applying Immediate Constituent Analysis technique (ICA) as a basic technique. A book entitled Gadis Korek Api and others fairy-tale are the work of danish author, H.C. Andersen that used Indonesian standard. The analysis showed syntactic structure of fairy-tale language which form of sentence pattern based on the user, the pattern of imperative sentence, sentence pattern contains conjunction, and sentence pattern of complex sentences. Keywords: Sentence Pattern; Fairy-tale; Syntactic.</p

RASES: A database supported framework for structured model base management
No full textStructured management of model base has placed demands on some kind of computer based frameworks with highly structured formalisms. This paper proposes a new framework, called the relational algebraic system entity structure (RASES), which is based on the system entity structure (SES) formalism and the relational algebra (RA) formalism. These formalisms provide a conceptual basis for the structured model base management. Within the framework, structural knowledge of a system is represented in a hierarchical structure and saved in a database. Furthermore, several operations can be formulated in terms of relational algebra which can be coded in a standard query language such as the SQL. The framework can be easily implemented on, and fully utilize the functionality of, relational database management system (RDBMS). With the help of the implemented framework, simulation models can be systematically synthesized from the models in the model base through the following processes. First, a family of hierarchical structures of a system is organized in the form of entity structure by the entity structuring process. Then, candidate models of the system which meet design objectives are synthesized from the entity structure through the pruning process. Finally, designers can conduct appropriate experiment with the models for design verification and performance measure. ？ 1997 Elsevier Science B.V
