We introduce a new diagrammatic approach to perturbative quantum field theory, which we call flow-oriented perturbation theory (FOPT). Within it, Feynman graphs are replaced by strongly connected directed (digraphs). FOPT is coordinate space analogue of time-ordered and loop-tree duality, but it has the advantage having combinatorial canonical rules, combined with simplified $i\varepsilon$ depe...

this paper presents an appropriate categorization of business processes in order to study the different aspects of knowledge management for each kind of business processes. in this categorization, business processes are classified into the four categories including work-flow oriented, decision oriented, information oriented and motivation oriented. then, the special attributes and knowledge man...

We present a seemingly new definition of flows and flow numbers for oriented matroids and prove that the flow number ΦL and the antisymmetric flow number ΦLas of an oriented matroid are bounded with its rank. In particular we show that if O is an oriented matroid of rank r then ΦL(O) ≤ r + 2 and ΦLas(O) ≤ 3b 9 2 rc+1. Furthermore, we introduce the notion of a semiflow and show that each oriente...

OBJECTIVE To evaluate breathing pattern and thoracoabdominal motion during breathing exercises. METHODS Twenty-four patients with class II or III obesity (18 women; 6 men) were studied on the second postoperative day after gastroplasty. The mean age was 37 +/- 11 years, and the mean BMI was 44 +/- 3 kg/m(2). Diaphragmatic breathing, incentive spirometry with a flow-oriented device and incenti...

The ability to debug programs composed using aspect-oriented programming (AOP) techniques is critical to the adoption of AOP. Nevertheless, many AOP systems lack adequate support for debugging, making it difficult to diagnose faults and understand the program‘s composition and control flow. We present an AOP debug model that characterizes AOP-specific program composition techniques and AOP-spec...

There are several methods for mining communities on the Web using hyperlinks. One of the well-known ones is a max-flow based method proposed by Flake et al. The method adopts a page-oriented framework, that is, it uses a page on the Web as a unit of information, like other methods including HITS and trawling. Recently, Asano et al. built a site-oriented framework which uses a site as a unit of ...
