Operational Characteristics

Regulations and policies contain a rich source of requirements and failure to address these authoritative requirements in software system development can impose costly penalties for regulatory noncompliance. Despite the advancement of information system research, regulatory requirements compliance remains one of the primary challenges still to be efficiently dealt in system development because of the scarce information, complexity, and understanding of available approaches in requirements engineering process of a system development. This paper reports a systematic literature review of the documented approaches of regulatory requirements compliance, classifies these approaches according to different criteria and provides a qualitative analysis of their operational characteristics. The results of this analysis can serve system developers as the means of deriving appropriate methods and tools for regulatory requirements compliance in the software system development.

Conceptual Research

Requirements engineering is the process of discovering the purpose and implicit needs of a software system that will be developed and making explicit, complete, and non ambiguous their specification. Its relevance is based in that omission or mistakes generated during this phase and corrected in later phases of a system development lifecycle, will cause cost overruns and delays to the project, as well as incomplete software. This chapter, by using a conceptual research approach, reviews the literature for developing a review of types of requirements, and the processes, activities, and techniques used. Analysis and synthesis of such findings permit to posit a generic requirements engineering process. Implications, trends, and challenges are then reported. While its execution is being mandatory in most SDLCs, it is done partially. Furthermore, the emergence of advanced services-oriented technologies suggests further research for identifying what of the present knowledge is useful and what is needed. This research is an initial effort to synthesize accumulated knowledge.

Thick Medium

TEM characterization and microanalysis of the recording media is crucial and complementary to new material system development as well as quality control applications. Due to the type of material generally used for supporting the medium, i.e., a polymer, conventional macro- and microthinning procedures for thin foil preparation are not applicable. Ultramicrotorny (UM) is a viable option and has been employed in previous similar studies. In this work UM has been used for preparation of XTEM samples from a magneto-optical (MO) recording medium in its original production format.The as-received material system consisted of a 4-layer, 2100 Å thick medium including a 300 Å TbFeCo layer enveloped by silicon nitride protective layers supported on a 1.2 mm thick × 135 mm (5.25 in.) diameter polycarbonate disk. Recording tracks had an approximate pitch of 1.6 μm separated by 800 Å deep peripheral grooves. Using a Buehler Isomet low-speed diamond saw, 1 mm wide and 20 mm long strips were cut out of the disk along the recording tracks.
