When a.hyperela.tic memb.a.e tub. is infla.ed b. a. interna. pressure, a.loca.ized b.lge will form when the pressure rea.hes a.critica. va.ue. a. infla.ion continues the b.lge will grow until it rea.hes a.ma.imum size a.ter which it will then propa.a.e in b.th directions to form a.ha.-like profile. The sta.0}lity of such b.lging solutions ha. recently b.en studied b. neglecting the inertia.of the infla.ing fluid a.d it wa. shown tha. such b.lging solutions a.e unsta.0}e under pressure control. In this pa.er we extend this recent study b. a.suming tha. the infla.ion is b. a. inviscid fluid whose inertia.we ta.e into a.count in the sta.0}lity a.a.ysis. This reflects more closely the situa.ion of a.eurysm forma. tion in huma. a.teries which motiva.es the current series of studies. It is shown tha. fluid inertia.would significa.tly reduce the growth ra.e of the unsta.0}e mode a.d thus it ha. a.strong sta.0}lizing effect.

The construction of la.ge softwa.e systems is a.wa.s a.hieved through a.semb.y of independently written components -- progra. modules. For these softwa.e components to work together, they must sha.e a.common set of da.a.types a.d principles for representing structured da.a.such a. a.ra.s of va.ues a.d files. This common set of tools for crea.ing a.d opera.ing on da.a.ob.ects is provided b. the infra.tructure of the computer system： the ha.dwa.e, opera.ing system a.d runtime code. b.ca.se the na.ure a.d properties of these tools a.e crucia. for correct opera.ion of softwa.e components a.d their inter-opera.ion, it is essentia. to ha.e a.precise specifica.ion tha. ma. b. used for verifying correctness of a.plica.ion softwa.e on one ha.d, a.d to verify correctness of system b.ha.ior on the other. We ca.l such a.specifica.ion a.progra. execution model （PXM）. It is evident tha. the properties of the PXM implemented b. a.computer system ca. ha.e serious impa.t on the a.0}lity of a.plica.ion progra.mers to pra.tice modula. softwa.e construction. This pa.er discusses the concept of progra. execution models a.d presents a.set of principles tha. a.PXM must sa.isfy to provide a.sound b.sis for modula. softwa.e construction. b.ca.se pa.a.lel progra. execution on computer systems with ma.y processing units is a. essentia. pa.t of contempora.y computing environments, the expression of pa.a.lelism a.d modula. softwa.e construction using components involving pa.a.lel opera.ions is included in this trea.ment.

It is found tha. a.nozzle with contra.ting a.gle of 45° genera.es the most sta.0}e a.d fa.test single droplet, which is b.neficia. for the enha.ced printing qua.ity a.d high-throughput printing ra.e. For this nozzle with the optima. geometry, we systema.ica.ly cha.ge the wetta.0}lity of the interior surfa.e, i.e., different conta.t a.gles. a. the conta.t a.gle increa.es, pinch-off time increa.es a.d the droplet speed reduces.
