Agile Methodologies

Despite its weaknesses (such as described in the 1975 collection of essays The Mythical Man Month [11]), the traditional software development life cycle (collect requirements, design, implement, test, deploy, maintain) has remained the standard framework for software development. However, in recent years it has become clear that the life cycle is not well suited to applications that are experimental in nature (i.e., where there is no precedent for the particular kind of application) or that exist in rapidly changing environments. This has led to the development of agile methodologies (also known as lightweight... 

In extreme programming and other agile methodologies, refactoring is an integral part of the software development cycle developers alternate between adding new tests and functionality and refactoring the code to improve its internal consistency and clarity. 

Abstract A relatively small number of mammalian pheromones has been identified, in contrast to a plethora of known insect pheromones, but two remarkable Asian elephant/insect pheromonal linkages have been elucidated, namely, (Z)-7-dodecen-1-yl acetate and frontalin. In addition, behavioral bioassays have demonstrated the presence of a chemical signal in the urine of female African elephants around the time of ovulation. Our search for possible ovulatory pheromones in the headspace over female African elephant urine has revealed for the first time the presence of a number of known insect pheromones. This search has been facilitated by the use of a powerful new analytical technique, automated solid phase dynamic extraction (SPDE)/GC-MS, as well as by novel macros for enhanced and rapid comparison of multiple mass spectral data files from Agilent ChemStation . This chapter will focus on our methodologies and results, as well as on a comparison of SPDE and the more established techniques of solid phase microextraction (SPME) and stir bar sorptive extraction (SBSE).

Figure 4.11 Quantitative analysis software for chromatography. Since the signal from the detector situated at the outlet of the column is analogical, an analogue-digital converter (ADC) is necessary. The stored chromatogram, digitized, serves as a basis for its exploitation hy the software. Different zones of the screen can display the calibration curve, methodology, etc. (software Chemstation from Agilent Technologies).

The software application is composed by two main parts according to the client-server design methodology and based on the reusing principle which is an agile approach for short-time releasing of software to the customers. 

Another trend is the use of agile design and development, where fast prototyping, test-driven, model-driven and behavior-driven development methodologies allow focusing on business cases and semantic interoperability issues.

Agile approach is discussed in hterature, and importance of human factor is stressed, while technical aspects are presented usually in a general way. The research starts with development of methodology for identification of structure of technical resources and their status (own/shared).
