Risk [Failed failsafe] v Resilience [Safe to fail]David Wilson
Whilst conventional risk management are "trending" toward the rather woolly concept of "risk culture" without sound theory and the ability to objectively measure much of great importance, courtesy of the capabilities developed by Ontonix, the new discipline of "Resilience Management" offers a rigorous quantitative approach to aid real-time, verifiable, decision-making.
When risk, in the Digital Age, evolves at such pace that even real-time observation may not be adequate, management techniques that rely upon reflexive analysis are woefully inadequate. Enabled by measurement, Resilience Management identifies sources of weakness that may impair the system's ability to absorb the unforeseen, therefore reducing risk and uncertainty by extending the risk horizon, to provide "crisis anticipation" or "anticipatory awareness"

we focus on the forces and influences that are at work as the architect begins creating-envisioning-the central artifact of the system whose influences persist beyond lifetime of the system

Software Architecture Standard IEEE 1471vconovalov
This presentation covers the IEEE 1471/4210 Architecture Standard for the Software Intensive System. Following areas such as Stakeholders and their concerns, Architecture Description and System Qualities Attributes were mainly addressed. The audience consisted of Development leads, developers & testers. Hope other disciplines such as Architects and Business Analysts will find it useful as well.
NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

This document provides information about the third edition of the magazine "Sthapatya" published by the Association of Civil Engineers (Practicing) Aurangabad. It includes messages from current and past presidents of ACEP, memories and photos from past ACEP events, information on life time achievement awards given by ACEP, and a technical article on concrete maintenance, repairs and strengthening. The document highlights activities of ACEP and provides a technical educational article for members.
3. A system is a set of interacting or interdependent components forming an
integrated whole.
A system is a set of elements (often called ‘components’ instead) and
relationships which are different from relationships of the set or its elements
to other elements or sets.
4. 1. STRUCTURE : defined by components/elements and
their composition;
2. BEHAVIOR : which involves inputs, processing and
outputs of material, energy, information, or data;
3. INTERCONNECTIVITY: the various parts of a system have
functional as well as structural relationships to each other.
