The article has analyzed the connotation of the idea of large-scale engineering education and the challenges of higher engineering education. On this basis, this paper pertinently puts forward some countermeasures to strengthen the higher engineering education reform: clearing the target of engineering education, strengthening engineering practice and humanistic quality education, innovating the personnel training mode, and enhancing the ability of teaching staff.

Decisive Parameters for Backwater Effects Caused by Floating Debris Jams  [PDF]
Arnd Hartlieb
Open Journal of Fluid Dynamics (OJFD) , 2017, DOI: 10.4236/ojfd.2017.74032
The dimensional analysis of the backwater effect caused by debris jams results in the Froude number of the approach flow in the initial situation prior to debris jam formation and the debris density as decisive parameters. For the more precise detection of the influence of both parameters the results of different hydraulic model test series at the Laboratory of Hydraulic and Water Resources Engineering of the Technical University of Munich concerning debris jams at spillways as well as at racks for the retention of wooden debris were uniformly evaluated. On the one hand a significant increase of the backwater effect with a rising Froude number of the approach flow could be shown. This is in good correlation to recent test results for debris jams at retention racks at the Laboratory of Hydraulics, Hydrology and Glaciology of the Swiss Federal Institute of Technology Zurich. On the other hand a significant increase of the backwater effect could also be shown for a rising debris density. However, the test results also show that significantly different backwater effects can occur in different test runs with identical test conditions. These differences are a result of the randomness of debris jam development, and therefore, a more exact quantification of the dependence of the backwater effect on the Froude number of the approach flow and on the debris density is not considered useful for the present results.
Hermeneutical Elicitation of Requirements: A Technical Perspective to Improve the Conception of the Software Requirements  [PDF]
Wagner Varalda, ítalo Santiago Vega
Journal of Computer and Communications (JCC) , 2018, DOI: 10.4236/jcc.2018.69010
Abstract: In order to develop quality software that meets the originals needs of its users, it is necessary to perform the Requirements Engineering, so that the software context to be developed is identified, examined and specified properly. However, there is a problem that is increasingly in debate: the difficulty in understanding and establishing the purpose of the software to be developed, as pointed out by important researches in the area, such as the Chaos Report, which indicates that only 29% of software projects are successful, and the Software Engineering Institute, which points out software requirements as a critical factor for the success of software engineering and that deficiencies in this dimension are the main causes of software project failures. This article presents a proposal to address this problem through the use of the Hermeneutical Elicitation of Requirements, which is the conceptual adequacy of some hermeneutical methods in a technical approach that assists the requirements engineer to conceive better of the software requirements. In this way, the software engineer will be better able to develop the software to better meet the needs of its end users and sponsors.

Chinese Science Bulletin , 2007, DOI: 10.1007/s11434-007-7003-7
Abstract: This paper takes the interaction between engineering construction and ecosystem changes as the main science issue. Based on the DPSIR (Drive-Press-State-Impact-Response) framework, this study analyzes the interlinkage of interaction between engineering construction and ecosystem changes from the aspect of drive, press, state, impact and response, brings forward the interaction model, interaction scenario analysis method and interaction index (drive-response index, IIDR, drive-impact index, IIDI, impact-response index, IIIR, impact index, IIII), and advances the corresponding calculation models and interaction index system. And also this paper adopts the different interaction indexes to respect the impact on and response to engineering construction, and takes the Manwan hydropower station and road traffic construction in the Longitudinal Range-Gorge Region (LRGR) as example to analyze and validate the interaction model. By the systematic analysis of the outcome, the IIDR, IIDI, IIIR and IIII of construction and operation of Manwan hydropower station are respectively 3.67, 3.92, 14.35 and 0.35. There is no remarkable variance of interlinkage elements in interaction system, and exploitation of hydropower station benefits the sustainable development of regional environment and society based on the supposition of without considering the environment cost, diffusion effect, potential negative effect and potential responses of hydropower station construction. Through some case studies, the interaction model we built shows very good practical value in interaction quantitative analyzing and interaction index system constructing.
The information activity of rail passenger information staff: a foundation for information system requirements
Martin Rose
Information Research: an international electronic journal , 2006,
Abstract: Introduction. This paper examines the goal-directed information activity of passenger information staff, working in the dynamic environment of rail network control. The explicit aim is to define a meaningful set of information system requirements. The report shows how dynamic situations may lead us to question a number of established theories of information science. Method. Passenger information officers (PIOs) were observed on duty within the rail command and control headquarters. Observation sessions totally eight hours involved the manual recording of sequential information flows and the associated activity of PIOs. A semi-structured management interview was also conducted to provide further insight into the organizational context. Analysis. A viewpoint-oriented analysis technique was used to analyse sequential data captured during observation sessions. Event sequences that represent and explain the viewpoints were identified and elaborated into detailed scenario descriptions. Results. The analysis both supports and contests a number of established theories from information science. Additionally, a range of 'mandatory' and 'desirable' system requirements are derived from the scenario and viewpoint analyses. Conclusion. Dynamic situations have a significant impact on information behaviour which is not always predicted by current theories of information science.
Building Requirements Semantics for Networked Software Interoperability  [PDF]
Bin Wen, Keqing He, Jian Wang
Journal of Software Engineering and Applications (JSEA) , 2010, DOI: 10.4236/jsea.2010.32016
Abstract: Naturally, like the web, integrated software systems in Internet will have to be distributed and heterogeneous. To im-prove the interoperability of services for SAAS, it is crucial to build requirements semantics that will cross the entire lifecycle of services especially on requirements stage. In this paper, a requirements semantics interoperability extend-ing approach called Connecting Ontologies (CO) that will act as semantics information carrier designing to facilitate the requirements identification and services composition is proposed. Semantic measurement of Chinese scenario is explored. By adopting the approach, a series of tools support for transport domain are developed and applied based on CO and DPO (Domain Problem Ontology) to enforce requirements engineering of networked software efficiently.
A New Maturity Model for Requirements Engineering Process: An Overview  [PDF]
Badariah Solemon, Shamsul Sahibuddin, Abdul Azim Abdul Ghani
Journal of Software Engineering and Applications (JSEA) , 2012, DOI: 10.4236/jsea.2012.55040
Abstract: It is widely acknowledged that Requirements Engineering (RE) has an important implication for the overall success of software or system development projects. As more and more organizations consider RE as the principal problem areas in the projects, improving RE process therefore appears critical for future business success. Moreover, nowadays there are evidences that support improving RE process maturity can contributes to improved business performance. There exist generic Software Process Improvement (SPI) standards, specialised RE process improvement models as well as guidance and advices on RE. However, they suffer from various issues that limit their adoption by organizations that are interested to assess and improve their RE process capability. Therefore, the research presented in this paper proposes a new RE process improvement model. The model is built by adapting and expanding the structure of the continuous representation of the formal maturity framework Capability Maturity Model Integration for Development (CMMI-DEV) developed by the Software Engineering Institute (SEI) through three rounds of development and validation stages, which involved RE and CMMI expert panel in the software industry. This paper aims to provide an overview on what, why and how we build the maturity model for RE. The intention is to provide a foundation for future development in the area of RE process improvement.
Icons: Visual Representation to Enrich Requirements Engineering Work  [PDF]
Sukanya Khanom, Anneli Heimbürger, Tommi K?rkk?inen

Adapting icons in requirements engineering can support the multifaceted needs of stakeholders. Conventional approaches to RE are mainly highlighted in diagrams. This paper introduces icon-based information as a way to represent ideas and concepts in the requirements engineering domain. We report on icon artifacts that support requirements engineering work such as priority types, status states and stakeholder kinds. We evaluate how users interpret meanings of icons and the efficacy of icon prototypes shaped to represent those requirements attributes. Our hypothesis is whether practitioners can recognize the icons’ meaning in terms of their functional representation. According to the empirical data from 45 participants, the findings demonstrate the probability of providing users with icons and their intended functions that correspond to RE artifacts in a novel yet effective manner. Based on these findings, we suggest that icons could enrich stakeholders’ perception of the RE process as a whole; however, meaningful interpretation of an icon is subject to the user’s prior knowledge and experience.
