Mit rechnergesteuerten Einrichtungen haben es heute nicht nur Ingenieure und Informatiker zu tun, sondern mehr und mehr Menschen mit unterschiedlichem fachlichen Hintergrund, mit verschiedenartigen Aufgaben in wechselnden Situationen und mit unterschiedlicher Motivation. Die vielschichtige Gemeinschaft der Anwender solcher Systeme und deren Einsatzszenarien wachsen rasch. Die Spannweite reicht ...

PSP (Personal Software Process) methodology developed by SEI (Software Engineering Institute) aims to help developers to produce highquality software products. Software developers who use PSP can analyze their personal process performance based on the collected individual performance metrics and improve their personal development processes to perfect their work habits and to make more accurate ...

The latest advances in the stabilization of Li/Na metal battery and Li-ion cycling have highlighted importance electrode/electrolyte interface [solid electrolyte interphase (SEI)] its direct link to behavior. To understand structure properties SEI, we used combined experimental computational studies unveil how ionic liquid (IL) cation nature salt concentration impact silicon/IL interfacial form...

Ideal Adsorbed Solution Theory (IAST) is a common method for modelling mixture adsorption isotherms based on pure component isotherms. When the adsorbent has distinct sites, segregated version of IAST (SIAST) provides improved adsorbed loadings compared to IAST. We have adopted concept SIAST and applied it an explicit isotherm model which takes into account different sizes adsorbates: so called...

Since the release of Building Systems from Commercial Components [Wallnau 01] in July of 2001, the design and engineering team from the SEI COTS-Based Systems Initiative has developed the collection of techniques described in that book into a more prescriptive COTS-based systems design process. This evolution has been partially described in this column and other forums and will soon be offered ...

A new method for determining the vitrification rate of pottery depending on the firing temperature was devised using secondary electron images (SEI) of scanning electron microscope (SEM). Several tests were performed to establish the appropriate operating conditions of SEM and reproducibility as well as to examine the applicability of the method. The grayscale values converted from each pixel o...

Progress in rational engineering of Li-ion batteries requires better understanding of the electrochemical processes and accompanying transformations in the electrode materials on multiple length scales. In spite of recent progress in utilizing transmission electron microscopy (TEM) to analyze these materials, in situ scanning electron microscopy (SEM) was mostly overlooked as a powerful tool th...

Developed by the Software Engineering Institute (SEI) at Carnegie Mellon University, Software Quality Requirements Engineering for Acquisition (A-SQUARE) is a methodology used for eliciting and prioritizing security requirements as part of the acquisition process. In the project described in this paper, we evaluated the effectiveness of the A-SQUARE method by applying it to a COTS product for t...

In December 2001 the SEI CMMI Product Team released version 1.1 of the Capability Maturity Model Integrated for Systems Engineering and Software Engineering (CMMI-SE/SW 1.1). After several years of preparation the CMMI replaced both the CMM version 1.1 of 1993 (SW-CMM) and the systems engineering standard EIA 731. According to the SEI survey data, several hundred organisations from all over the...
