Recently, the development of knowledge bases is considered to be a process of extending an ontology with specific knowledge of a particular application. Reuse of pre-existing knowledge sources gives rise to knowledge bases endowed with a common and standard terminology. But, reuse often requires an enormous effort, so few knowledge-based applications have arisen following this approach. In this...

This paper reports on the use of tools that statically analyze rule-bases in order to detect logical errors, such as redundancy, inconsistency, and incompleteness. The analysis uses a variant of the KB-Reducer algorithm (Ginsberg 1991). In contrast to accounts of similar tools, which seldom describe tools as used in the field, the experience described in this paper is derived from using tools t...

DISCOVER1 (DIStribution COunter VERsion 1) is a new program that can identify DNA motifs occurring with a high deviation from the expected frequency. The program generates families of patterns, each family having a common set of defined bases. Undefined bases are inserted amongst the defined bases in different ways, thus generating the diverse patterns of each family. The occurrences of the dif...

Jilin Province is one of the principal production bases of traditional Chinese medicine (TCM) in China with its typical preponderance in TCM resources, research and development power, and industrialization capacity. The province has 2,790 species of TCM materials in total. Over 20% of the TCM materials in common use are from Jilin Province. The province has established 36 good agricultural prac...

An algorithm and its first implementation in C# are presented for assembling arbitrary quantum circuits on the base of Hadamard and Toffoli gates and for constructing multivariate polynomial systems over the finite field Z2 arising when applying the Feynman’s sum-over-paths approach to quantum circuits. The matrix elements determined by a circuit can be computed by counting the number of common...

In this paper we present a general and very simple construction for generating complete orthonormal bases for system identiication. This construction provides a unifying formulation of orthonormal bases since the common FIR and recently popular Laguerre and Kautz model structures are restrictive special cases of our construction. A distinguishing feature of our construction is that it can gener...

background: prevalence of obesity in the world, in both developed and developing countries, is growing rapidly. bariatric surgery is now accepted as the treatment for morbid obesity. objective: this study compares laparoscopic sleeve gastrectomy's effectiveness (lsg) with the most common bariatric surgery, laparoscopic roux-en-y (lrygb) gastric bypass.   methods: a systematic review was perform...

This paper describes a unified theory for autocalibration of a moving camera. The camera models can be 2D projective, 2D affine camera and 1D projective projections. The scenes can be either non-planar scenes or planar scenes and the camera may also undergoes a pure rotation. All these cases are unified into the same framework based on the direction bases. Each formulation on the direction base...

Missing values are an old problem that is very common in real data bases. We describe the damages caused by missing values on condensed representations of patterns extracted from large data bases. This is important because condensed representations are very useful to increase the efficiency of the extraction and enable new uses of patterns (e.g., rules with minimal body, clustering, classificat...
