In this paper we study the Arc Orienteering Problem in directed and undirected graphs. To the best of our knowledge, we give the fist approximation algorithms for both the undirected and the directed versions of the problem. Our main results are the following: (i) We give an O( log 2(m) log log(m) )−approximation algorithm for the AOP in directed graphs, where m is the number of arcs of the gra...

The transperineal ultrasound (TPU) value of the angle of progression (AOP) during fetal head engagement, at station 0, is a critical cut-off for current obstetrical practice, especially when intrapartum instrumental interventions are required. Still, controversial measurements were reported in previous high resolution imagistic studies. Our TPU and direct "gold-standard" magnetic resonance (MRI...

Aspect-Oriented Software Development (AOSD) is one of the newest approaches for managing complexity by further modularizing code for large software systems. Software code continues to grow in size as well as complexity [1]. Aspect-Oriented Programming (AOP) is meant to improve modularity, and reduce complexity by separation of concerns in code. AOP is designed to work with programming languages...

The need for comparison between AOP and related approaches has been retained as a key issue in [MLTK97]. We have noticed strong similarities between AOP and some object-oriented approaches including some notion of viewpoint. We report them in this paper and we discuss how this brief comparison may be used for further discussion of the other key issues that were retained in [MLTK97].

the state-based behavior of AOP program with the consideration of the interactions between the base modules and aspects. Based on the model, test cases can be derived so as to uncover the potential state behavior errors in the AOP programs. In addition, an example is provided to show the effectiveness of the proposed approach.

Analytically oriented psychotherapy (AOP) has been considered the treatment of choice for borderline patients and a useful technique in the treatment of schizotypal patients. There are many exceptions, however, in addition to a number of borderline and schizotypal patients who are just barely amenable to this modality: they are at the border of treatability by AOP. Limitations relating to time,...

The goal of the paper is to present that Aspect Oriented Programming AspectJ integrated with Spring AOP provides very powerful mechanisms for modularizing enterprise security cross-cutting concerns. Aspect-oriented programming (AOP) allows weaving a security aspect into an application providing additional security functionality or introducing completely new security mechanisms.Spring’s proxy-ba...

In the 60s and 70s the software engineering offensive emerged from long-standing problems in software development, which are captured by the term software crisis. Though there has been significant progress since then, the current situation is far from satisfactory. According to the recent report of the Standish Group, still only 34% of all software projects succeed. Since the early days, two fu...

BACKGROUND Type II diabetes mellitus is a complex heterogeneous group of metabolic conditions characterized by an increased level of blood glucose, due to impairment in insulin action and/or insulin secretion. Hyperglycemia is a major factor in the pathogenesis of atherosclerosis in diabetes. Oxidative modification of low density lipoprotein (LDL) is recognized as one of the major processes inv...
