Power-law energy level-spacing distributions in fractals
In this article we investigate the energy spectrum statistics of fractals at
the quantum level. We show that the energy-level distribution of a fractal
follows a power-law behaviour, if its energy spectrum is a limit set of
piece-wise linear functions. We propose that such a behaviour is a general
feature of fractals, which can not be described properly by random matrix
theory. Several other arguments for the power-law behaviour of the energy
level-spacing distributions are proposed
Analisis Perilaku Voice sebagai Moderator Hubungan antara Ketidakpuasan Kerja dan Kreativitas
This study examined the effect of job dissatisfaction to creativity, as main effect. And also investigate whether Commitment Continuance and some of Contextual variables could significantly moderate the relationship between job dissatisfaction and creativity The sample research was employees (Educative and Administrative Employee) at the Private High School in Semarang. Of the 225 questionnaire were distributed, 213 questionnaire were returned to the researcher (response rate 94%). Twenty two of these were excluded from the data analysis because of missing value, not give the same code and no code, leaving sample of 184.It was hypothesized that Job Dissatisfaction would affect significantly to Creativity. It was also hypothesized that Commitment Continuance and some of Contextual Variables simultaneously would significantly moderated the relationship between Job Dissatisfaction and Creativityi The result of Simple Rgression Analysis indicated that Job Dissatisfaction had no significant effect on Creativity. Based on Moderated Regression Analysis, the results were not supported the predicted moderating effect of Continuance Commitment and Some of Contextual Variables simultaneously in relationship between Job Dissatisfaction to Creativity. The result warrant future research
A Novel QoS provisioning Scheme for OBS networks
This paper presents Classified Cloning, a novel QoS provisioning mechanism for OBS networks carrying real-time
applications (such as video on demand, Voice over IP, online
gaming and Grid computing). It provides such applications with a minimum loss rate while minimizing end-to-end delay and jitter. ns-2 has been used as the simulation tool, with new OBS modules having been developed for performance evaluation purposes. Ingress node performance has been investigated, as well as the overall performance of the suggested scheme. The results obtained showed that new scheme has superior performance to classical cloning. In particular, QoS provisioning offers a guaranteed burst loss rate, delay and expected value of jitter, unlike existing proposals for QoS implementation in OBS which use the burst offset time to provide such differentiation. Indeed, classical schemes increase both end-to-end delay and
jitter. It is shown that the burst loss rate is reduced by 50% reduced over classical cloning
On Solving Pentadiagonal Linear Systems via Transformations
Many authors have studied numerical algorithms for solving the linear systems of pentadiagonal type. The well-known fast pentadiagonal system solver algorithm is an example of such algorithms. The current paper describes new numerical and symbolic algorithms for solving pentadiagonal linear systems via transformations. The proposed algorithms generalize the algorithms presented in El-Mikkawy and Atlan, 2014. Our symbolic algorithms remove the cases where the numerical algorithms fail. The computational cost of our algorithms is better than those algorithms in literature. Some examples are given in order to illustrate the effectiveness of the proposed algorithms. All experiments are carried out on a computer with the aid of programs written in MATLAB
Public Release of RELXILL_NK: A Relativistic Reflection Model for Testing Einstein's Gravity
We present the public release version of relxill_nk, an X-ray reflection
model for testing the Kerr hypothesis and general relativity. This model
extends the relxill model that assumes the black hole spacetime is described by
the Kerr metric. We also present relxilllp_nk, the first non-Kerr X-ray
reflection model with a lamppost corona configuration, as well as all other
models available in the full relxill_nk package. In all models the relevant
relativistic effects are calculated through a general relativistic ray-tracing
code that can be applied to any well-behaved, stationary, axisymmetric, and
asymptotically flat black hole spacetime. We show that the numerical error
introduced by using a ray-tracing code is not significant as compared with the
observational error present in current X-ray reflection spectrum observations.
In addition, we present the reflection spectrum for the Johannsen metric as
calculated by relxill_nk.Comment: 15 pages, 8 figures. v2: refereed version. Code and documentation

Testing the Kerr metric with X-ray Reflection Spectroscopy of Mrk 335 Suzaku data
Einstein's gravity has undergone extensive tests in the weak field
gravitational limit, with results in agreement with theoretical predictions.
There exist theories beyond general relativity (GR) which modify gravity in the
strong field regime but agree with GR in the weak field. Astrophysical black
holes are believed to be described by the Kerr metric and serve as suitable
candidates to test strong gravity with electromagnetic radiation. We perform
such a test by fitting one Suzaku dataset of the narrow-line Seyfert 1 (NLS1)
galaxy Mrk 335 with X-ray reflection spectroscopy, using the Johannsen metric
to model the black hole spacetime and test for deviations from Kerr. We find
the data is best modeled with a hybrid model that includes both partial
covering absorption and a reflection component. This is the first time such a
model has been proposed for a high-flux (low reflection) Mrk 335 dataset. We
constrain the Johannsen deformation parameter to
, and the
parameter to , both at the 99%
confidence level. Although additional solutions at large deviations from the
Kerr metric show statistical similarity with the ones above, further analysis
suggests these solutions may be manifestations of uncertainties beyond our
control and do not represent the data. Hence, our results are in agreement with
the idea that the supermassive compact object at the center of Mrk 335 is
described by the Kerr metric.Comment: 13 pages, 9 figures. v2: refereed versio
