Knowledge, information, and modern technologies have become some of the most influential drivers of today's society, consequently leading to a high popularity of the concepts of big data (BD). However, their actual harnessing is a demanding task that is accompanied by many barriers and challenges. To facilitate the realization of the corresponding projects, the (big) data science engineering process (BDSEP) has been devised to support researchers and practitioners in the planning and implementation of data intensive projects by outlining the relevant steps. However, the BDSEP is only geared towards a test last development approach. With recent works suggesting the application of test driven development (TDD) in the big data domain, it appears reasonable to also provide a corresponding TDD focused equivalent to the BDSEP. Therefore, in the publication at hand, using the BDSEP as a foundation, the test driven big data science engineering process (TDBDSEP) is proposed, facilitating the application of TDD in the big data domain and further enriching the discourse on BD quality assurance.

big data play an indispensable role not only in the cognitive mechanisms of human sensation, quantification, qualification, estimation, memory, and reasoning, but also in a wide range of engineering applications. A basic study on the theoretical foundations of big data science is presented with a coherent set of general principles and analytic methodologies for big data systems. Cognitive foundations of big data are explored in order to formally explain the origination and nature of big data. A set of mathematical models of big data are created that rigorously elicit the general essences and patterns of big data across pervasive domains in sciences, engineering, and societies. A significantfinding towards big data science is that big data systems in nature are a recursive n-dimensional-typed hyperstructure (RNTHS) rather than pure numbers. The fundamental topological property of big data reveals a set of denotational mathematical solutions for dealing with inherited complexities and unprecedented challenges in big data engineering.

The advancement of portable X-ray digital radiography devices is currently hindered by the limited penetration depth, limit of detection (LoD), and spatial resolution of commercially available scintillators for X-ray imaging. In this study, data mining engineering is proposed to boom X-ray imaging quality via the auto-discovery of potentially overlooked inorganic scintillators. This mining criteria encompassed the comprehensive set of screening parameters, including equivalent substitution, structural rigidity, effective atomic number, and material density. Among 27 389 potential candidates identified in this analysis, Lu2WO6:Eu3+ scintillator is successfully mined with the feature of light yield at approximate to 27 600 photons/MeV. This scintillator exhibits a low LoD of approximate to 8.5 nGyair s-1- significantly lower than the standard dosage typically employed in X-ray diagnostics. It also demonstrats exceptional reliability in terms of penetration depth and spatial resolution for X-ray imaging at distances of 51.9 mm and line pairs per millimeter values of 18.2, respectively. The peripheral X-ray leakage dose of the portable DR device is restricted to only 682 uSv h-1, thus ensuring safe usage without necessitating additional protective measures while enabling various applications such as indoor or outdoor high-voltage wire damage detection and field first aid. We proposed data mining engineering to boom X-ray imaging quality via the auto-discovery of potentially overlooked inorganic scintillators. A overlooked scintillator, Lu2WO6:Eu3+, was mined with a light yield at 27600 photons/MeV and a low limit of detection at 8.5 nGyair/s. This scintillator film exhibited deep penetration depth (51.9 mm) and high spatial resolution (18.2 lp/mm) for X-ray imaging, respectively. image

This study has been undertaken to amalgamate the principles of Site Reliability engineering and data engineering to effectively measure, monitor and manage the reliability of petabyte-scale data engineering process from collection at source to processing, analyzing, and distributing the data for appropriate decision making to improve business outcomes and system performance. Modern data architectures increasingly leverage cloud platforms, low-code systems, and serverless technologies to enable scalable data engineering. However, these innovations also introduce new complexities regarding reliability assurance. As these failure-prone yet business-critical data infrastructures continue rapid adoption, it is vital to elucidate architectural paradigms, quantified benchmarks, and procedural methodologies tailored to safeguarding dependability across heterogeneous, distributed data ecosystems. This paper will equip end users with a reusable framework ingrained with best practices to develop a blueprint for data reliability across business units of an organization.

The ability to process large amounts of data and to extract useful insights from data has revolutionised society. This phenomenon dubbed as big data has applications for a wide assortment of industries, including the construction industry. The construction industry already deals with large volumes of heterogeneous data;which is expected to increase exponentially as technologies such as sensor networks and the Internet of Things are commoditised. In this paper, we present a detailed survey of the literature, investigating the application of big data techniques in the construction industry. We reviewed related works published in the databases of American Association of Civil Engineers (ASCE), Institute of Electrical and Electronics Engineers (IEEE), Association of Computing Machinery (ACM), and Elsevier Science Direct Digital Library. While the application of data analytics in the construction industry is not new, the adoption of big data technologies in this industry remains at a nascent stage and lags the broad uptake of these technologies in other fields. To the best of our knowledge, there is currently no comprehensive survey of big data techniques in the context of the construction industry. This paper fills the void and presents a wide-ranging interdisciplinary review of literature of fields such as statistics, data mining and warehousing, machine learning, and big data Analytics in the context of the construction industry. We discuss the current state of adoption of big data in the construction industry and discuss the future potential of such technologies across the multiple domain-specific sub-areas of the construction industry. We also propose open issues and directions for future work along with potential pitfalls associated with big data adoption in the industry. (C) 2016 Elsevier Ltd. All rights reserved.

Context MapReduce is a processing model used in big data to facilitate the analysis of large data under a distributed architecture. Objective The aim of this study is to identify and categorize the state of the art of software testing in MapReduce applications, determining trends and gaps. Method Systematic mapping study to discuss and classify according to international standards 54 relevant studies in relation to reasons for testing, types of testing, quality characteristics, test activities, tools, roles, processes, test levels, and research validations. Results The principal reasons for testing MapReduce applications are performance issues, potential failures, issues related to the data, or to satisfy the agreements with efficient resources. The efforts are focused on performance and, to a lesser degree, on functionality. Performance testing is carried out through simulation and evaluation, whereas functional testing considers some program characteristics (such as specification and structure). Despite the type of testing, the majority of efforts are focused at the unit and integration test levels of the specific MapReduce functions without considering other parts of the technology stack. Conclusions Researchers have both opportunities and challenges in performance and functional testing, and there is room to improve their research though the use of mature and standard validation methods.

作者： Wang, Yingxu Peng, Jun Chongqing Univ Sci & Technol Sch Elect & Informat Engn Chongqing Peoples R China

big data are pervasively generated by human cognitive processes, formal inferences, and system quantifications. This paper presents the cognitive foundations of big data systems towards big data science. The key perceptual model of big data systems is the recursively typed hyperstructure (RTHS). The RTHS model reveals the inherited complexities and unprecedented difficulty in big data engineering. This finding leads to a set of mathematical and computational models for efficiently processing big data systems. The cognitive relationship between data, information, knowledge, and intelligence is formally described.

作者： Wang, Yingxu Wiebe, Victor J. Univ Calgary ICIC Calgary AB Canada

big data are products of human collective intelligence that are exponentially increasing in all facets of quantity, complexity, semantics, distribution, and processing costs in computer science, cognitive informatics, web-based computing, cloud computing, and computational intelligence. This paper presents fundamental big data analysis and mining technologies in the domain of social networks as a typical paradigm of big data engineering. A key principle of computational sociology known as the characteristic opinion equilibrium is revealed in social networks and electoral systems. A set of numerical and fuzzy models for collective opinion analyses is formally presented. Fuzzy data mining methodologies are rigorously described for collective opinion elicitation and benchmarking in order to enhance the conventional counting and statistical methodologies for big data analytics.

In the Information Age, Machine learning (ML) provides a competitive advantage to any business. Machine learning applications are not limited to driverless cars or online recommendations but are widely used in healthcare, social services, government systems, telecommunications, and so on. As many enterprises are trying to step up machine learning applications, it is critical to have a long-term strategy. Most of the enterprises are not able to truly realize the fruits of ML capabilities due to its complexity. It is easier to access a variety of data today due to data democratization, distributed storage, technological advancements, and big data applications. Despite easier data access and recent advancements in ML, developers still spend most of the time in data cleansing, data preparation, and data modeling for ML applications. These steps are often repeated and result in identical features. As identical features can have inconsistent processing while testing and training, more issues pop up at later stages in ML application development. The unification of ML features is an effective way to address these issues. This paper presents details about numerous methods to achieve ML features unification.
