Today's environments of increasing business change require software development methodologies that are more adaptable. This article examines how complex adaptive systems (CAS) theory can be used to increase our understanding of how agile software development practices can be used to develop this capability. A mapping of agile practices to CAS principles and three dimensions (product, process, and people) results in several recommendations for "best practices" in systems development.

Flaxseed imparted the evidence of health benefits in human being. Response surface methodology (RSM) was employed to develop flaxseed fortified rice -corn flour blend based extruded product using twin screw extruder. The effect of roasted flaxseed flour (RFF) fortification (15-25 %), moisture content of feed (12-16 %, wb), extruder barrel temperature (120-140°C) and screw speed (300-330 RPM) on expansion ratio (ER), breaking strength (BS), bulk density (BD) and overall acceptability (OAA) score of extrudates were investigated using central composite rotatable design (CCRD). Increased RFF level decreased the ER and OAA score significantly while increased BS and BD of extrudates (p<0.01). Moisture content of extruder feed was positively related to ER (p<0.01) and OAA (p < 0.05) and negatively related to BD (p < 0.01). Extruder barrel temperature was found to be negatively related to ER and OAA (p<0.05) and positively related to BD (p<0.1). Quadratic effect of screw speed was significantly positively related to ER (p < 0.01), BS (p<0.05) and negatively related to BD (p<0.01). 15 % RFF fortification with rice flour, 16 % moisture content (wb) of extruder feed, 120°C extruder barrel temperature and 330 RPM of screw speed gave an optimized product of high desirability with corresponding responses as 3.08 ER, 0.53 kgf BS, 0.106 g.cm −3 BD and 7.86 OAA.

In the last few years, wireless networking has seen considerable interest among service providers, users, vendors and content developers. Significant advances have been made in devices, applications, middleware and networking infrastructure. With wireless becoming such a mainstream technology, there is a growing interest in increasing its usage in the enterprise environment. Before wireless solutions can be deployed widely, the requirements of the enterprise environment and capabilities and limitations of wireless technologies must be addressed. In this study, we analyse and discuss the enterprise requirements and how such requirements can be met by the current and emerging wireless infrastructure. In particular, the major requirements are dependability, security, coverage, ease-of-use, devices, network interoperability and cost. Some of these requirements are addressed in the paper, and we also present a dependable, secure and scalable solution for the emerging wireless enterprise. Since this is an emerging area, we present several possible approaches to conduct research in wireless enterprise.
