The ability of Gaussian noise to induce ordered states in dynamical systems is here presented in an overview of the main stochastic mechanisms able to generate spatial patterns. These mechanisms involve: (i) a deterministic local dynamics term, accounting for the local rate of variation of the field variable, (ii) a noise component (additive or multiplicative) accounting for the unavoidable env...

Localized ecological interactions can generate striking large-scale spatial patterns in ecosystems through spatial self-organization. Possible mechanisms include oscillating consumer-resource interactions, localized disturbance-recovery processes and scale-dependent feedback. Despite abundant theoretical literature, studies revealing spatial self-organization in real ecosystems are limited. Rec...

Project management is an important factor to accomplish the decision to implement large-scale software systems (LSS) in a successful manner. The effective project management comes into play to plan, coordinate and control such a complex project. Project management factor has been argued as one of the important Critical Success Factor (CSF), which need to be measured and monitored carefully duri...

  During fixation of a femoral neck fracture in a 23-year-old male patient with cannulated screws, a broken guide wire fragment inadvertently advanced through the hip joint and protruded into the pelvis. A second surgical approach was needed to remove the broken fragment from the pelvis. Awareness of such a potentially devastating complication will make surgeons more cautious during implementa...

introduction: knowledge management is one of the most interesting and challenging issues of management in the new millennium. educational and research institutions such as libraries and information centers are the most suitable places for the implementation of knowledge management programs. this study aimed to identify and rank the factors affecting the implementation of knowledge management in...
