The Architectural Dynamics of Encapsulated Botnet Detection (EDM)
Botnet is one of the numerous attacks ravaging the networking environment.
Its approach is said to be brutal and dangerous to network infrastructures as
well as client systems. Since the introduction of botnet, different design
methods have been employed to solve the divergent approach but the method of
taking over servers and client systems is unabated. To solve this, we first
identify Mpack, ICEpack and Fiesta as enhanced IRC tool. The analysis of its
role in data exchange using OSI model was carried out. This further gave the
needed proposal to the development of a High level architecture representing
the structural mechanism and the defensive mechanism within network server so
as to control the botnet trend. Finally, the architecture was designed to
respond in a proactive state when scanning and synergizing the double data
verification modules in an encapsulation manner within server system
Das Kreuz mit dem Kreuz : wenn Wirbelsäule und Bandscheiben verschleißen – Abgestuftes Therapiekonzept ermöglicht differenzierte Behandlung
Rückenschmerzen bezeichnen die Mediziner inzwischen als Volkskrankheit oder gar als Epidemie der Neuzeit. So leiden zirka 80 Prozent der Deutschen wenigstens einmal in ihrem Leben an Kreuzschmerzen, 35 Prozent davon langfristig. Zirka 20 Millionen Bundesbürger begaben sich beispielsweise 1999 wegen derartiger Beschwerden in ärztliche Behandlung; keine andere Krankheit verursacht so viele Krankenhausaufenthalte. Beträgt die Krankheitsdauer mehr als sechs Monate, kehrt lediglich jeder Zweite in den Arbeitsprozess zurück. Während früher sehr viel schneller gravierende operative Methoden eingesetzt wurden, hat sich in den vergangenen Jahren ein abgestuftes Therapiekonzept entwickelt, das sich sehr differenziert an dem jeweiligen Stadium der Erkrankung ausrichtet

Efficient multi-scale modelling of path dependent problems – complas 2017
With growing capabilities of computers use of multi-scale methods for detailed analysis of response with respect to material and geometric nonlinearities is becoming more relevant. In this paper focus is on MIEL (mesh-in-element) multi-scale method and its implementation with AceGen and AceFEM based on analytical sensitivity analysis. Such implementation enables efficient multi-scale modelling, consistency and quadratic convergence also for two-level path following methods for the solution of path dependent problems
Scale-free Universal Spectrum for Atmospheric Aerosol Size Distribution for Davos, Mauna Loa and Izana
Atmospheric flows exhibit fractal fluctuations and inverse power law form for
power spectra indicating an eddy continuum structure for the selfsimilar
fluctuations. A general systems theory for fractal fluctuations developed by
the author is based on the simple visualisation that large eddies form by
space-time integration of enclosed turbulent eddies, a concept analogous to
Kinetic Theory of Gases in Classical Statistical Physics. The ordered growth of
atmospheric eddy continuum is in dynamical equilibrium and is associated with
Maximum Entropy Production. The model predicts universal (scale-free) inverse
power law form for fractal fluctuations expressed in terms of the golden mean.
Atmospheric particulates are held in suspension in the fractal fluctuations of
vertical wind velocity. The mass or radius (size) distribution for homogeneous
suspended atmospheric particulates is expressed as a universal
scale-independent function of the golden mean, the total number concentration
and the mean volume radius. Model predicted spectrum is in agreement (within
two standard deviations on either side of the mean) with total averaged radius
size spectra for the AERONET (aerosol inversions) stations Davos and Mauna Loa
for the year 2010 and Izana for the year 2009 daily averages. The general
systems theory model for aerosol size distribution is scale free and is derived
directly from atmospheric eddy dynamical concepts. At present empirical models
such as the log normal distribution with arbitrary constants for the size
distribution of atmospheric suspended particulates are used for quantitative
estimation of earth-atmosphere radiation budget related to climate
warming/cooling trends. The universal aerosol size spectrum will have
applications in computations of radiation balance of earth-atmosphere system in
climate models.Comment: 18 pages, 5 figures. arXiv admin note: substantial text overlap with

Single charge and exciton dynamics probed by molecular-scale-induced electroluminescence
Excitons and their constituent charge carriers play the central role in
electroluminescence mechanisms determining the ultimate performance of organic
optoelectronic devices. The involved processes and their dynamics are often
studied with time-resolved techniques limited by spatial averaging that
obscures the properties of individual electron-hole pairs. Here we overcome
this limit and characterize single charge and exciton dynamics at the nanoscale
by using time-resolved scanning tunnelling microscopy-induced luminescence
(TR-STML) stimulated with nanosecond voltage pulses. We use isolated defects in
C thin films as a model system into which we inject single charges and
investigate the formation dynamics of a single exciton. Tuneable hole and
electron injection rates are obtained from a kinetic model that reproduces the
measured electroluminescent transients. These findings demonstrate that TR-STML
can track dynamics at the quantum limit of single charge injection and can be
extended to other systems and materials important for nanophotonic devices
