The Elizabethan Anti-stage Movement
Criticism of the theater in the Elizabethan period was not the first thing happened in the history of the world\u27s drama. Most historians and critics agree that the antitheatrical prejudice began with Plato. The Platonic belief in the reality of the Idea was often referred to in later arguments against the stage. According to Plato, the physical world is not real because it is an imitation of the Idea and only the Idea is the Truth. Thus, art is three times removed from the Truth because it is an imitation of the physical world. In the Elizabethan era, the anti-stage arguments were later intensified with the conflict of power among the Church, the City and the Court
Video in development : filming for rural change
This book is about using video in rural interventions for social change. It gives a glimpse into the many creative ways in which video can be used in rural development activities. Capitalising on experience in this field, the books aims to encourage development professionals to explore the potential of video in development, making it a more coherent, better understood and properly used development tool - in short, filming for rural change
Strong convergence rates of probabilistic integrators for ordinary differential equations
Probabilistic integration of a continuous dynamical system is a way of
systematically introducing model error, at scales no larger than errors
introduced by standard numerical discretisation, in order to enable thorough
exploration of possible responses of the system to inputs. It is thus a
potentially useful approach in a number of applications such as forward
uncertainty quantification, inverse problems, and data assimilation. We extend
the convergence analysis of probabilistic integrators for deterministic
ordinary differential equations, as proposed by Conrad et al.\ (\textit{Stat.\
Comput.}, 2017), to establish mean-square convergence in the uniform norm on
discrete- or continuous-time solutions under relaxed regularity assumptions on
the driving vector fields and their induced flows. Specifically, we show that
randomised high-order integrators for globally Lipschitz flows and randomised
Euler integrators for dissipative vector fields with polynomially-bounded local
Lipschitz constants all have the same mean-square convergence rate as their
deterministic counterparts, provided that the variance of the integration noise
is not of higher order than the corresponding deterministic integrator. These
and similar results are proven for probabilistic integrators where the random
perturbations may be state-dependent, non-Gaussian, or non-centred random
variables.Comment: 25 page

Fasilitas Pelatihan Cadd di Makassar
CADD (Computer Aided Design & Drafting) merupakan alat bantu program yang banyak digunakan di berbagai kalangan profesi saat ini seperti arsitek, kontraktor, mekanikal, industri seni, animasi, dan berbagai profesi lainnya. Setelah munculnya CADD mulai terjadi peralihan, dari yang dulunya orang-orang yang masih menyajikan gambar dengan menggunakan tangan hingga sekarang semuanya menggambar dengan menggunakan CADD. Hal ini tentunya tidak mengherankan mengingat dengan menggunakan CADD mereka memperoleh banyak keuntungan, baik dari gambar yang dihasilkan jauh lebih cepat, lebih akurat, serta kualitas gambar yang dihasilkan jauh lebih bersih dan rapi jika dibandingan dengan menggunakan tangan. Maraknya perkembangan teknologi dan informasi membuat semuanya terasa lebih mudah karena telah menggunakan komputer dalam memudahkan pekerjaan. Tapi berbagai kemudahan ini perlu ditunjang pula dengan kemampuan yang mencukupi. Oleh karena inilah diajukan perancangan Fasilitas Pelatihan CADD di Makassar dimana nantinya fasilitas ini mampu memberikan pengetahuan tentang CADD dan mempersiapkan calon-calon profesional bidang tertentu untuk lebih siap dalam menghadapi tuntutan di dalam dunia kerja nantinya
Effects of momentum-dependent nuclear potential on two-nucleon correlation functions and light cluster production in intermediate energy heavy-ion collisions
Using an isospin- and momentum-dependent transport model, we study the
effects due to the momentum dependence of isoscalar nuclear potential as well
as that of symmetry potential on two-nucleon correlation functions and light
cluster production in intermediate energy heavy-ion collisions induced by
neutron-rich nuclei. It is found that both observables are affected
significantly by the momentum dependence of nuclear potential, leading to a
reduction of their sensitivity to the stiffness of nuclear symmetry energy.
However, the t/He ratio remains a sensitive probe of the density
dependence of nuclear symmetry energy.Comment: 20 pages, 11 figure
Invariants of differential equations defined by vector fields
We determine the most general group of equivalence transformations for a
family of differential equations defined by an arbitrary vector field on a
manifold. We also find all invariants and differential invariants for this
group up to the second order. A result on the characterization of classes of
these equations by the invariant functions is also given.Comment: 13 page

Exchange coupling between two ferromagnetic electrodes separated by a graphene nanoribbon
In this study, based on the self-energy method and the total energy
calculation, the indirect exchange coupling between two semi-infinite
ferromagnetic strips (FM electrodes) separated by metallic graphene nanoribbons
(GNRs) is investigated. In order to form a FM/GNR/FM junction, a graphitic
region of finite length is coupled to the FM electrodes along graphitic zigzag
or armchair interfaces of width . The numerical results show that, the
exchange coupling strength which can be obtained from the difference between
the total energies of electrons in the ferromagnetic and antiferromagnetic
couplings, has an oscillatory behavior, and depends on the Fermi energy and the
length of the central region.Comment: 4 pages, 6 figures, International Conference on Theoretical Physics
