The paper discusses the reasons of complexity rise in ERP system SAP R/3 and proposes a method for measuring complexity of SAP. A program in ABAP for measuring complexity of particular SAP implementation is proposed as a tool for keeping ERP complexity under control. Main principle of the measurement method is counting the number of items or relations in the system. The program is based on coun...

The gamma-ray excited, temperature dependent scintillation characteristics of CsI(Tl) are reported over the temperature range of -100 to +50°C. The modified Bollinger-Thomas and shaped square wave methods were used to measure the rise and decay times . Emission spectra were measured using a monochromator and corrected for monochromator and photocathode spectral efficiencies . The shaped square ...

Transition time constraints are ubiquitous in scheduling problems. They are said to be sequence-dependent if their durations depend on both activities between which they take place. In this context, we propose to extend the Θ-tree and Θ-Λ-tree data structures introduced by Vilím in order to strengthen the bound computation of the earliest completion time of a set of activities, by taking into a...

There are many different definitions of the risetime of a transient waveform. In the context of HEMP standards, the 10-90% risetime of an idealized double exponential waveform has been defined and used for many decades. However, such a risetime definition is not strictly applicable to the transient voltage out of a pulse generator, since no practical switch can close in zero time. In this paper...

We propose that freshwater calcite microbialites may represent an alternative trajectory toward a community ecology aggregate that achieves some of the biological functions perfected by macroorganismic communities. A distinctive assemblage of microbialites studied at Pavilion Lake, British Columbia, Canada, could be a prototypical example of this transitional stage of biological organization. T...

the term globalization undoubtedly has affected all parts of humanity life in current century. globalization as a comprehensive phenomenon has influenced economical, political, social and cultural aspects of our societies. contemporary architecture as a multidimensional category is depended on various factors and needs to be pursued in different fields, in order to reach to a perfect comprehend...

an artificial neural network (ann) was used to analyse the capillary rise in porous media. wetting experiments were performed with fifteen liquids and fifteen different powders. the liquids covered a wide range  of  surface  tension ( 15.45-71.99  mj/m2 )  and  viscosity (0.25-21 mpa.s). the powders also provided an acceptable range of particle size (0.012-45 μm) and surface free energy (25.54-...

In contrast to entropy, which increases monotonically, the “complexity” or “interestingness” of closed systems seems intuitively to increase at first and then decrease as equilibrium is approached. For example, our universe lacked complex structures at the Big Bang and will also lack them after black holes evaporate and particles are dispersed. This paper makes an initial attempt to quantify th...

The concept of "complexity" is familiar to most of project's managers, but it is not comprehended in the same way. although the complexity highlights negative points, but it may bring positive advantages which support the project. Researches conducted on this field show that the understanding of "complexity" between the researchers is different and it is mainly depends on th...

the origin the concept of lz compexity is in information science. here we use this notion to characterize chaotic dynamical systems. we make contact with the usual characteristics of chaos, such as lyapunov exponent and k-entropy. it is shown that for a two-dimensional system lz complexity is as powerful as other characteristics. we also apply lz complexity to the study of the quasiperiodic fib...
