In this paper, we describe how traditional systems engineering processes, such as those delineated in the ANSI//EIA 632 standard, are becoming inadequate for today’s complex systems, in which there is a rich set of interconnections and interrelationships between all of the systems in an enterprise. We further suggest that a new discipline (or an extension of the old discipline) is developing in...

This report presents a conceptual framework for multi-level modeling of complex sociotechnical systems, provides linkages to the historical roots and technical underpinnings of this framework, and outlines a catalog of component models for populating multi-level models. This includes a description of the “systems movement,” a summary of philosophical underpinnings, a review of seminal concepts,...

Nowadays much emphasis is given to innovative procurement in the road construction sector. However, typical discussions about it do not focus on all the stakeholders involved in the process and all aspects. However, one cannot forget that procurement is a complex system, and everyone’s perspective is important for success. This paper looks at the worldviews of stakeholders in the road construct...

there are two dominant approaches to describe and understand the anatomy of complete health and well-being systems internationally. yet, neither approach has been able to either predict or explain occasional but dramatic crises in health and well-being systems around the world and in developed emerging market or developing country contexts. as the impacts of such events can be measured not simp...

Abstract The wireless channel is characterized by large statistical variations, which results in wide variations in its response. If the system is designed to meet the worst conditions of the channel, the throughput will be very small and the efficiency will degrade. On the other hand, if the system is designed to track the channel variations, it will yield a larger throughput. In this work, we...

Adaptive algorithms lead to adjust the system coefficients based on the measured data. This paper presents a dichotomous coordinate descent method to reduce the computational complexity and to improve the tracking ability based on the variable forgetting factor when there are a lot of changes in the system. Vedic mathematics is used to implement the multiplier and the divider in the VFF equatio...

A common trend in modern applications is the move towards more mobile, adaptive, customisable software. The evolution of software from static, invariant tools for narrow portions of a task to adaptive, open interaction frameworks is embodied in the use of a variety of technologies for creating a reconfigurable application. Perhaps the two most important techniques are Adaptive architectures and...

An expert panel was convened to explore the use of adaptive implementation in the TMDL program, following a 2001 National Research Council report recommendation. This paper summarizes the panel’s report suggesting an adaptive implementation process for water quality management. In current practice, what the panel calls standard implementation, a plan for reducing pollutant loads to meet water q...

The study presented in this paper underlines the capacity increase resulting from the joint use of Multi-Carrier (MC) adaptive modulation techniques and MC-CDMA receiver in the context of Beyond 3G systems. The performance enhancement due to such near optimal rate and power adaptation decreases with diversity order. Moreover, results obtained through two different kinds of Wireless Channels (ET...

The discussion of the adaptive landscape in the philosophical literature appears to be divided along the following lines. On the one hand, some claim that the adaptive landscape is either “uninterpretable” or incoherent. On the other hand, some argue that the adaptive landscape has been an important heuristic, or tool in the service of explaining, as well as proposing and testing hypotheses abo...
