Abstract

The concept of deterministic theory underlying quantum mechanics, usually referred to as “hidden variable theories”. For instance, one may or may not assume the occurence of information loss at tiny distance scales. One may suspect some sort of cellular automaton or a classical system of continuous fields, or even classical loops, D-branes, or whatever. We discuss Gerardus ‘t Hooft idea that refer to as pre-quantization, where the physical system is not modified and complex systems are handled probabilistically. Our results for harmonic oscillators indicate that the energy eigenstates of a quantum system are going to be nice. The next one urgent question must be answered is how to construct explicit models in which energy can be seen extrinsic and how can we find its limit cycles. An atractive related problem that found by us is how to introduce weak interactions between two nearly independent systems.

Abstract

In this paper, a new symmetry argument in a vacuum state with strictly vanishing vacuum energy has been studied. This argument exploits the well-known feature that deSitter and Anti-deSitter space are related by analytic continuation in complex analysis. When we drop boundary and hermiticity conditions on quantum fields, we get as many negative as positive energy states, which are related by transformations to complex space. In this case, we have explored indirectly a new perspective to solve cosmological constant problem.

Abstract

Analisis laju kondensasi akibat pengaruh kecepatan udara (V) terhadap karakteristik perpindahan panas oven pengering pati sagu telah diteliti dengan perpindahan panas konveksi paksa dan diaplikasikan untuk mendesain oven pengering pati sagu guna menjawab kebutuhan masyarakat yang selama ini menggunakan cara pengeringan tradisional. Model uji dimodifikasi dengan memberikan saluran udara masuk dan keluar agar bilangan Nusselt meningkat dengan masukan panas (Q*) = 5.400 kJ/hr konstan. Penelitian eksperimen dilakukan dengan variasi kecepatan udara (V) = 0.7 s/d 1.0 m/s, untuk mengamati karakteristik perpindahan panas dan laju kondensasi. Karakterik perpindahan panas meningkat seiring dengan membesarnya kecepatan udara. Semakin besar kecepatan udara untuk (V) < 0.9 m/s, maka karakteristik perpindahan panas konveksi dan laju kondensasi semakin meningkar dengan gradient kenaikan besar, sedangkan untuk kecepatan udara (V) > 0.9 m/s karakteristik perpindahan panas dan laju kondensasi meningkat pula dengan gradient kenaikan kecil. Karakteristik perpindahan panas yakni bilangan Prandt (Pr) meningkat dari 0.6969 hingga 0.6974 atau meningkat sebesar 0.08%, bilangan Reynold (Re) meningkat dari 233667.092 hingga 34216.484 atau meningkat sebesar 6.83%, bilangan Nusselt (Nu) maningkat dari 762.576 hingga 1084.454 atau meningkat sebesar 29.68%, koefisien konveksi (h) meningkat dari 102.718 kJ/jam..m2.K hingga 124 kJ/jam.m2.K atau meningkat sebesar 17.16%, laju perpindahan panas konveksi (qk) meingkat dari 12542.551 kJ/jam hingga 15395.773 kJ/jam atau meningkat sebesar 18.53%. Laju kondensasi meningkat dari 0.152 kg/hr-m hingga 0.171 kg/hr-m atau meningkat sebesar 11.11%.
