FINITE DIFFERENCE APPROXIMATIONS FOR MEASURE-VALUED SOLUTIONS OF A HIERARCHICALLY SIZE-STRUCTURED POPULATION MODEL

*MATHEMATICAL BIOSCIENCES AND ENGINEERING*, *12*(2), 233–258.

author keywords: Hierarchically size-structured population model; measure-valued solutions; finite-difference approximations; convergence analysis

MeSH headings : Algorithms; Computer Simulation; Finite Element Analysis; Humans; Models, Statistical; Population Density; Population Dynamics; Time Factors

Bandwidth estimation for video streaming under percentile delay, jitter, and packet loss rate constraints using traces

*COMPUTER COMMUNICATIONS*, *57*, 73–84.

author keywords: Activity-based simulation; Bandwidth estimation; Video traces; Percentile end-to-end delay; Packet loss rate

TL;DR:
A CPU-efficient activity-based simulation model is presented and it is shown that the bandwidth required for n identical video streams that follow the same path through an IP network, so that the end-to-end percentile delay remains the same, is a linear function of n.

Measuring the benefits of ERP on supply management maturity model: a "big data" method

*INTERNATIONAL JOURNAL OF OPERATIONS & PRODUCTION MANAGEMENT*, *35*(1), 2–25.

Contributors: Y. Huang^{ n} & R. Handfield^{ n}

author keywords: Procurement; Information management; Buyer-supplier relationships

TL;DR:
This study provides an extensive analysis of how the deployment of ERPs systems and the selection of ERP vendors can benefit a company’s supply chain performance and suggests ERP users are more mature than non-ERP users in three key indicators: strategic sourcing, category management, and supplier relationship management.
