Complete Submodularity Characterization in the Comparative Independent Cascade Model

Comparative Study of Two Various Percent of CO Injection Effect to Cascade Methanol Synthesis Reactor in the Presence of Long-term Catalyst Deactivation

A History Sensitive Diffusion Network: Preliminary Model and Simulation

Diffusion is a process by which information, viruses, ideas and new behavior spread over social networks. The traditional independent cascade model gives activated nodes a one-time chance to activate each of its neighboring nodes with some probability. This paper extends the traditional model to an iterative fashion. We propose a model called the iterative cascade model that allows activated no...

Nano selenium-lovastatin mixture modulate inflammatory cascade in arthritic irradiated model

Background:  The development of nanotechnology has been a boon to mankind as its significance paved the way for several applications in therapeutics. This study was to evaluate the anti-arthritic capability of nano Selenium-lovastatin mixture (Lov-Se) against inflammatory cascade in arthritic irradiated rats. Materials and Methods: Animal model of Arthritis was organized by subcutaneous in...

History Sensitive Cascade Model, Midterm Report

We introduce and define the History Sensitive Cascade Model. We then explore how vertices are activated in this model. We introduce the notion of how many vertices are expected to be activated after some time, given that some vertices are active initially. We show that this is NP-hard to compute exactly, and use submodularity to provide a lower bound on the approximation found by a greedy algor...

MTBF evaluation for 2-out-of-3 redundant repairable systems with common cause and cascade failures considering fuzzy rates for failures and repair: a case study of a centrifugal water pumping system

In many cases, redundant systems are beset by both independent and dependent failures. Ignoring dependent variables in MTBF evaluation of redundant systems hastens the occurrence of failure, causing it to take place before the expected time, hence decreasing safety and creating irreversible damages. Common cause failure (CCF) and cascading failure are two varieties of dependent failures, both l...
