the study of flight vehicle structures reveals the importance of obtaining the most suitable accuracy compatible with construction. for this purpose, several experiments were conducted at the agard institute. in this paper the results of one such experiment performed on a sample airplane wing are presented. aircraft structural engineers use several methods to model these structures. specifing h...

We present several examples of programs which ee-ciently monitor the answers from queries performed on data structures to determine if any errors are present. Our paper includes the rst eecient on-line error monitor for a data structure designed to perform nearest neighbor queries. Applications of nearest neighbor queries are extensive and include learning, categorization, speech processing , a...

(ABSTRACT) Several novel silica structures have been generated using a simulated-annealing strategy with an ab-initio based covalent-bonding potential. First-principles total-energy pseu-dopotential methods have been used to examine several promising novel structures and to compare their structural parameters, cohesive energies and bulk moduli with those of low-quartz, low-cristobalite, silica-...

Several THz electromagnetic band gap (EBG) structures are investigated and demonstrated. Various design, fabrication, and characterization methods and techniques are utilized and compared. These THz EBG structures may enable future high performance EBG based THz components. VC 2010 Wiley Periodicals, Inc.
