Goal-Oriented Requirements Engineering (GORE) has grown into an important area of research in the past decades. Still, some of its corners remain dark, since different GORE languages do not provide a well-founded conceptualization of the domain and are not consensual. This may lead to ambiguous or weak understanding of GORE concepts. In this paper, we introduce the Goal-Oriented Requirements Ontology (GORO), a domain ontology founded on the Unified Foundational Ontol-ogy (UFO) that intends to represent the nature and relations of concepts surrounding the GORE domain. We use GORO to explore and clarify the semantics used, sometimes implicitly, by well-known GORE languages.

This study explores the influence of wastewater feedstock composition on hydrothermal liquefaction (HTL) biocrude oil properties and physico-chemical characteristics. Spirulina algae, swine manure, and digested sludge were converted under HTL conditions (300 °C, 10–12 MPa, and 30 min reaction time). Biocrude yields ranged from 9.4% (digested sludge) to 32.6% (Spirulina). Although similar higher heating values (32.0–34.7 MJ/kg) were estimated for all product oils, more detailed characterization revealed significant differences in biocrude chemistry. Feedstock composition influenced the individual compounds identified as well as the biocrude functional group chemistry. Molecular weights tracked with obdurate carbohydrate content and followed the order of Spirulina < swine manure < digested sludge. A similar trend was observed in boiling point distributions and the long branched aliphatic contents. These findings show the importance of HTL feedstock composition and highlight the need for better understanding of biocrude chemistries when considering bio-oil uses and upgrading requirements.► Feedstock composition reflected in biocrude chemistry despite similar heating values. ► HTL biocrude N, O heteroatom content exceeds petroleum and requires upgrading. ► Feedstock selection and profiling critical for intended downstream application. ► Complementary analyses provide value-added data for biocrude oil characterization. ► Molecular-level profiling can aid in targeted treatments based on biocrude oil chemistry.

Requirements Engineering is the set of activities involved in creation, managing, documenting, and maintaining a requirements' set for a product. Engineering involves the use of systematic repeatability techniques to ensure that the Software Requirements are complete, consistent, valid, and verifiable. Software Requirements Specification is an organized process oriented toward defining, documenting and maintaining requirements throughout the development life cycle. Many authors suggest that requirements should always focus their claims on what the software product needs to address, without specifying how to implement them. However, the detail of Software Requirements is influenced by several factors such as: organizational thinking; existing specification standards; and regulatory needs. This work fits exactly with regulatory needs, where the characteristics of Software Requirements Specification in Regulated Environments such as aeronautics, railways and medical are presented and explored. This paper presents and analysis of software requirements specification characteristics in regulated environments. The four characteristics identified are: consistency (internal and external), unambiguity, verifiability, and traceability. The paper also describes the three standards used in these regulated environments (RTCA DO-178C, IEC 62279 and IEC 62304) and examines their similarities and differences from a Requirements Specification standpoint. The similarities and differences will be used to address a future requirements framework universal process that can be configured to address each standard by the usage of Software Process Lines.

In this paper we give the details on Non-Functional Requirements and its importance in various fields. We also investigate the effect of working out for the Non-functional Requirements which leads to the discovery of new Functional Requirements. After the coding phase in the Software Development Life Cycle (SDLC), during the process of articulating the Non-Functional Requirements the software analysts come up with the new unexpected Functional Requirements and which further creates a vicious circle. An effort is made to present the recent research in the field of finding, specifying and rectifying the Non - Functional attributes. This paper gives the details of past and current research, thus giving the ideas to researchers for future work.

All automated information systems (AIS) used on Department of Defense (DoD) data networks must register the data communication modes identifying the ports, protocols, and application services (PPS) used, and the network boundaries crossed. Compliance with the PPS requirements will reduce development time and cost, increase security, speed ecrtification and accreditation steps, enhance AIS interoperability across the department, and speed operational deployment of all new and updated AIS in DoD. This article introduces the PPS basic concepts, and demonstrates how developers and program anagers can comply with the PPS requirements, leverage the security analysis provided by the management office, and obtain the benefits listed.

The fast-paced, dynamic environment within which information and communication technology (ICT) projects are run as well as ICT professionals’ constant changing requirements present a challenge for project managers in terms of aligning projects’ requirements with project team members’ requirements. This research paper purports that if projects’ requirements are properly aligned with team members’ requirements, then this will result in a balanced decision approach. Moreover, such an alignment will result in the realization of employee’s needs as well as meeting project’s needs. This paper presents a Project’s requirements and project Team members’ requirements (PrTr) alignment model and argues that a balanced decision which meets both software project’s requirements and team members’ requirements can be achieved through the application of the PrTr alignment model.

To investigate different requirements related to m-learning projects, is important for the
development and analysis of them. In this sense, this paper has presented the results of a literature review on
requirements for mobile learning activities. Thus, it was selected as purchases related to the central scope of
this study, through the scientific examination of articles, theses and national and international dissertations
without the Bank of theses and periodicals of the Coordination of Improvement of Higher Education
Personnel. Those identified and mapped can help teachers and other professionals to use m-learning more
effectively in the educational context.

Outsourcing decisions are not, technically, irreversible. But in practical terms the organizational disruption and financial costs of bringing services back in house (“backsourcing”) mean that few organizations revert, even when quite dissatisfied with an arrangement. Instead, organizations typically seek to move to another outsourcing arrangement, that is sometimes less attractive than the original in-house delivery. Preliminary evidence from studies of business process outsourcing (BPO) experiences, like those into IT outsourcing’s success, suggests that only a minority of organizations report their BPO arrangements as satisfactory, implying that many are caught in this “can’t go back” bind. In this paper the authors examine two organizations contemplating the adoption of BPO, and consider their expectations and experiences in light of existing empirical literature. The paper concludes with a set of principles to assist organizations to avoid BPO failure.
