Scalings of t.e densit. peak and pellet.penet.at.on lengt. in It.R are developed based on simulat.ons using 1.5D BALDUR int.grat.d predict.ve modeling code. In t.ese simulat.ons, t.e pellet.ablat.on is described by t.e Neut.al Gas Shielding （NGS） model wit. grad-B drift.effect.t.ken int. account. t.e NGS pellet.model is coupled wit. a plasma core t.ansport.model, which is a combinat.on of an MMM95 anomalous t.ansport.model and an NCLASS neoclassical t.ansport.model. t.e BALDUR code wit. a combinat.on of MMM95 and NCLASS models, t.get.er wit. t.e NGS model, is used t. simulat. t.e t.me evolut.on of plasma current. ion and elect.on t.mperat.res, and densit. profiles for It.R st.ndard t.pe I ELMy H-mode discharges during t.e pellet.inject.on. As a result. t.e scaling of t.e densit. peak and pellet.penet.at.on lengt. at.peak densit. can be est.blished using t.is set.of predict.ve simulat.ons t.at.covers a wide range of It.R plasma condit.ons and pellet.paramet.rs. t.e mult.ple regression t.chnique is ut.lized in t.e development.of t.e scalings. It.is found t.at.t.e scaling for densit. at.cent.r is sensit.ve t. bot. t.e plasma and pellet.paramet.rs; whereas t.e scalings for densit. and locat.on of t.e addit.onal peak are sensit.ve t. t.e pellet.paramet.rs only.

Biological evidence suggest. t.at.fish use most.y ant.rior muscles for st.ady swimming while t.e caudal part.of t.e body is passive and, act.ng as a carrier of energy, t.ansfers t.e moment.m t. t.e surrounding wat.r. Inspired by t.ose findings we hypot.esize t.at.cert.in swimming pat.erns can be achieved wit.out.copying t.e dist.ibut.d act.at.on mechanism of fish but.rat.er using a single act.at.r at.t.e ant.rior part.t. creat. t.e t.avelling wave. t. t.st.t.e hypot.esis a pit.hing flexible fin made of silicone rubber and silicone foam was designed by copying t.e st.ffness dist.ibut.on profile and geomet.y of a rainbow t.out. t.e kinemat.cs of t.e fin was compared t. t.at.of a st.adily swimming t.out. Fin＇s propulsive wave lengt. and t.il-beat.am- plit.de were det.rmined while it.was act.at.d by a single servo mot.r.
