Current state of e-services in Saudi Arabia: the case of intermediaries in facilitating government services in Madinah city
The government of Madinah has launched âKhdamatecâ electronic Offices (e-Offices) concept under their national electronic Government (e-Government) modernisation agenda to facilitate service delivery to citizens and seamless interaction to communicate their needs. By offering e-Offices around the government departments, Madinah government hopes to increase accessibility of e-Government services and make steps forward to electronic age, encourage Medina' citizens to participate and use e-Services and bridging digital divide. However, the empirical findings illustrate that the adoption and diffusion of the e-Office concept and e-Government in the wider context at a lethargic pace. This paper highlights some of the challenges faced by the Madinah city in implementing the e-Office concept and e-Government
Non-local quantum effects in cosmology 1: Quantum memory, non-local FLRW equations and singularity avoidance
We discuss cosmological effects of the quantum loops of massless particles,
which lead to temporal non-localities in the equations of motion governing the
scale factor a(t). For the effects discussed here, loops cause the evolution of
a(t) to depend on the memory of the curvature in the past with a weight that
scales initially as 1/(t-t'). As one of our primary examples we discuss the
situation with a large number of light particles, such that these effects occur
in a region where gravity may still be treated classically. However, we also
describe the effect of quantum graviton loops and the full set of Standard
Model particles. We show that these effects decrease with time in an expanding
phase, leading to classical behavior at late time. In a contracting phase,
within our approximations the quantum results can lead to a bounce-like
behavior at scales below the Planck mass, avoiding the singularities required
classically by the Hawking-Penrose theorems. For conformally invariant fields,
such as the Standard Model with a conformally coupled Higgs, this result is
purely non-local and parameter independent.Comment: 18 pages, 13 figures - extra references added and minor wording

Regge behavior in effective field theory
We derive the Regge behavior for the forward scattering amplitude in scalar
field theory using the method of regions. We find that the leading Regge
behavior to all orders can be obtained. Regge physics emerges from a kinematic
region that involves the overlap of several modes, so that a careful treatment
of the overlap regions is important. The most consistent and efficient approach
utilizes graphs containing collinear, anti-collinear and Glauber modes, or
modes of SCET_GComment: 18 pages, 6 figure
MRI brain classification using support vector machine
The field of medical imaging gains its importance with increase in the need of automated and efficient diagnosis in a short period of time. Other than that, medical image retrieval system is to provide a tool for radiologists to retrieve the images similar to query image in content. Magnetic resonance imaging (MRI) is an imaging technique that has played an important role in neuroscience research for studying brain images. Classification is an important part in retrieval system in order to distinguish between normal patients and those who have the possibility of having abnormalities or tumor. In this paper, we have obtained the feature related to MRI images using discrete wavelet transformation. An advanced kernel based techniques such as Support Vector Machine (SVM) for the classification of volume of MRI data as normal and abnormal will be deployed
A physiologically inspired model for solving the cocktail party problem.
At a cocktail party, we can broadly monitor the entire acoustic scene to detect important cues (e.g., our names being called, or the fire alarm going off), or selectively listen to a target sound source (e.g., a conversation partner). It has recently been observed that individual neurons in the avian field L (analog to the mammalian auditory cortex) can display broad spatial tuning to single targets and selective tuning to a target embedded in spatially distributed sound mixtures. Here, we describe a model inspired by these experimental observations and apply it to process mixtures of human speech sentences. This processing is realized in the neural spiking domain. It converts binaural acoustic inputs into cortical spike trains using a multi-stage model composed of a cochlear filter-bank, a midbrain spatial-localization network, and a cortical network. The output spike trains of the cortical network are then converted back into an acoustic waveform, using a stimulus reconstruction technique. The intelligibility of the reconstructed output is quantified using an objective measure of speech intelligibility. We apply the algorithm to single and multi-talker speech to demonstrate that the physiologically inspired algorithm is able to achieve intelligible reconstruction of an "attended" target sentence embedded in two other non-attended masker sentences. The algorithm is also robust to masker level and displays performance trends comparable to humans. The ideas from this work may help improve the performance of hearing assistive devices (e.g., hearing aids and cochlear implants), speech-recognition technology, and computational algorithms for processing natural scenes cluttered with spatially distributed acoustic objects.R01 DC000100 - NIDCD NIH HHSPublished versio
