During the past several years, many enterprises have created data warehouses (and data marts) in order to run applications. Data warehousing technologies used have been primarily extract-transform-load (ETL) tools, database modeling and design tools, and relational database (RDB) systems. There are three major holes in data warehousing today. These include inadequate attention to dirty data, in...

We characterize long (up to 285 mm) gradient index (GRIN) lens endoscope systems for multiphoton imaging. We fabricate a portable, rigid endoscope system suitable for imaging unstained tissues, potentially deep within the body, using a GRIN lens system of 1 mm diameter and 8 cm length. The portable device is capable of imaging a ~200 µm diameter field of view at 4 frames/s. The lateral and axia...

The main motivation here is a question: whether any polyhedron which can be subdivided into convex pieces without adding a vertex, and which has the same vertices as a convex polyhedron, is infinitesimally rigid. We prove that it is indeed the case for two classes of polyhedra: those obtained from a convex polyhedron by “denting” at most two edges at a common vertex, and suspensions with a natu...

Graph data mining is highly versatile, as it applies not only to graph data but to relational data, as long as it can be represented as pairs of relationships. However, modeling RDBs as graphs using existing methods is limited in describing semantics of the relational data. In this paper, we propose a two-phased graph-modeling framework that converts any RDB to a directed graph with richer sema...

In the renewal of old process computer system of the continuous casting plant, Nippon Steel Corporation has attained cost reduction by the introduction of general-purpose PC server and OS, and middleware (NS SEMI SYSTEM) originally developed in the activity of open system solution. Also the adopting general purpose RDB to the continuous casting plant has been realized in the first time. The red...

We show that rigid reachability, the non-symmetric form of rigid E-unification, is undecidable already in the case of a single constraint. From this we infer the undecidability of a new rather restricted kind of second-order unification. We also show that certain decidable subclasses of the problem which are P-complete in the equational case become EXPTIME-complete when symmetry is absent. By a...

Paediatric bronchoscopy entails two endoscopic techniques: flexible and rigid bronchoscopy. Flexible bronchoscopy is mainly performed by pulmonologists, whereas rigid bronchoscopy is a more invasive procedure usually carried out by otorhinolaryngologists. Each method has advantages and drawbacks. The selection of flexible or rigid bronchoscopy depends on the indication, the clinical context and...

in this paper by using concepts of graph theory, forces method and substructure ing method for analysis of structures, some methods have been introduced for optimal analysis of structures in a large scale, using substructuring method. planar rigid frames assuming linear behavior and small deformations, have been optimal analyzed, by using forces method. thus, a fortran power station computation...

a 25 year-old construction worker underwent neck laceration following penetrating neck trauma in a falling incident. the 3rd tracheal ring was injured which was initially repaired and the patient was discharged in good general condition. (figure 1 shows the patient’s neck view after discharge from hospital).two months later the patient was again admitted due to provocative coughing and a metal ...
