The noise, called the Cook term, is ad­di­tive, Gauss­ian and mod­els ther­mal fluc­tu­a­tions dur­ing the cool­ing process. Math­e­mat­i­cally, the Cahn—Hilliard—Cook equa­tion is a semi­lin­ear, par­a­bolic, sto­chas­tic par­tial dif­fer­en­tial equa­tion with a non­lin­ear drift term which fails to be glob­ally Lip­schitz con­tin­u­ous, or even one-sided Lip­schitz con­tin­u­ous or glob­ally mo­not­one.

The equa­tion is dis­cretized by a fi­nite el­e­ment method com­ple­mented by Back­ward Euler time step­ping. In the talk we out­line how to prove strong con­ver­gence of the ap­prox­i­ma­tion as the dis­cretiza­tion pa­ra­me­ters van­ish.

Fer­rari and Zs. Mahsa Rafiee AlhossainiTarbiat Modares University és Miskolci Egyetem A multivariate location-scale model for clustered ordinal data Or­di­nal data ex­ists in many fields of study. Many types of data also have a hi­er­ar­chi­cal or clus­ter struc­ture.

Ex­tend­ing the meth­ods for di­choto­mous out­comes to or­di­nal out­comes has been ac­tively pur­sued. De­vel­op­ments have been mainly in terms of lo­gis­tic and pro­bit re­gres­sion mod­els. In par­tic­u­lar, be­cause the pro-por­tional odds as­sump­tion, which is based on the lo­gis­tic re­gres­sion for­mu­la­tion, is a com­mon choice for analy­sis of or­di­nal data.

Many of the mixed mod­els for or­di­nal data are gen­er­al­iza­tions of this model and in­clude the pro­por­tional odds as­sump­tion or its equiv­a­lent un­der the pro­bit or com­ple­men­tary log-log link func­tion. For non-pro­por­tional odds, dif­fer­ent ex­ten­sions of the pro­por­tional odds model are pre­sented. In a some­what dif­fer­ent ex­ten­sion of the pro­por­tional odds model, the scale of the re­gres­sor ef­fects are al­lowed to vary, in other words, the un­der­ly­ing vari­ance of the lo­gis­tic dis­tri­b­u­tion can vary as a func­tion of co­vari­ates.

Bináris opciós rendszer lurch bring­ing to­gether ex­ten­sions of the pro­por­tional odds model, for lon­gi­tu­di­nal or­di­nal data, a mixed or­di­nal lo­ca­tion-scale model was pre­sented which in­clude a log-lin­ear struc­ture for both the within-sub­ject and be­tween-sub­ject vari­ances, al­low­ing co­vari­ates to in­flu­ence both sources of bináris opciós rendszer lurch, and also in­clude a sub­ject-level ran­dom ef­fect in the within-sub­ject vari­ance spec­i­fi­ca­tion.

In this study, we ex­tended the lo­ca­tion-scale ap­proach for mul­ti­vari­ate clus­tered or­di­nal data to si­mul­ta­ne­ously model two or­di­nal out­comes.
