An enhanced weighted performance-based handover parameter optimization algorithm for LTE networks by Sas Bart, Spaey Kathleen, Jansen Thomas, Bălan Irina, Moerman Ingrid, Demeester Piet

“…<p>Abstract</p> <p>This article introduces an enhanced version of previously developed self-optimizing algorithm that controls the handover (HO) parameters of a long-term evolution base station in order to diminish and prevent the negative effects that can be introduced by HO (radio link failures, HO failures and ping-pong HOs) and thus improve the overall network performance. …”

Transfigurations of the Commonplace: Hirst’s Tumbler, Joyce’s Tap by Judith Woolf

“…In this paper, I shall consider how an early Damien Hirst mini-installation, consisting of a glass tumbler of water and a ping-pong ball, takes its only partly mocking place in a still life tradition going back to Roman <i>xenia</i> and seventeenth-century vanitas paintings, and to a related literary tradition typified by Thomas Hardy’s <i>Under the Waterfall</i> and James Joyce’s great prose aria to water all its forms in the Ithaca section of <i>Ulysses</i>.…”

Process Modelling of Isoamyl Acetate Synthesis Catalysed by Lipase from Candida antarctica in a Solvent-free System by Leong , Sim Siong, Azudin, Nurhazwani Yusoff, Shukor, Syamsul Rizal Abd

“…The objective of this work is to propose a reaction mechanism and develop a model for the synthesis of isoamyl acetate from isoamyl alcohol and acetate anhydride by using lipase from Candida antarctica in a solvent-free system. Ping-Pong Bi-Bi reaction mechanism with acetic anhydride and acetic acid inhibition is found to be the mechanism which is able to describe this reaction. …”
