Comparing Requirements Analysis Techniques in Business Intelligence and Transactional Contexts

Requirements elicitation is a key concern in information technology (IT) projects. Busi-ness intelligence systems (BI) have emerged and are now used widely in organizations. These systems are designed to support manager's decision-making in their business performance moni-toring activities and their requirements are very different from those of transactional systems. But past research did not consider these differences. Therefore, this paper relies on a comparative approach to assess differences in the level of use and perceived effectiveness of requirements analysis techniques in both business intelligence and transactional contexts. An exploratory quali-tative study was conducted with two phases of semi-structured interviews with experienced practitioners. Our results show that 28% of the techniques differ in their level of use or perceived effectiveness, thus demonstrating the specificity of decision makers' needs. Our results reveal the importance of using techniques appropriate to the context to adequately define requirements and improve projects’ success.

Prospect and challenges of analog switching for neuromorphic hardware

To inaugurate energy-efficient hardware as a solution to complex tasks, information processing paradigms shift from von Neumann to non-von Neumann computing architectures. Emerging electronic devices compete with speed, energy, and performance to revolutionize the neural hardware system where training and inference must achieve milestones. In this Perspective, we discuss the essential criteria for training and inference in various nonvolatile neuromorphic systems such as filamentary resistive switching, interfacial resistive switching, electrochemical random-access memory, and ferroelectric memory. We present a holistic analysis of technical requirements to design ideal neuromorphic hardware in which linearity is the critical aspect during training, whereas retention is the essential criterion of inference. Finally, we evaluate the prospect of a futuristic neuromorphic hardware system by optimizing the training and inference dilemma.

Analysis of geometric parameters and technical requirements for pin conical joints in pump nodes

The article analyzes the causes of the situation with the appearance of manufacturing errors and the lack of the necessary technical requirements to perform a pin conical joint his intended purpose. The analysis was performed based on geometric construction of the assembly dimensional chain of two parts to be connected and a conical pin with a taper 1:50 according to GOST 9465-79, which is used in the pin joints of pumping equipment. The geometric analysis included the separation of deviations into linear dimensions and angular deviations. The values of the angular deviations were reduced to the linear values of their projections along the axis of the pin, to determine the tolerance on the end height protrusion of the pin above the surface of the connecting parts. Also, the unfoundedness of assigning the roughness index of the hole under the pin at the level of Ra 1.6 μm and its inexpediency when it is impossible to ensure the required contact length is theoretically proved and the solution of this contradiction is proposed. A detailed analysis of the technical requirements for drawings of pumping equipment units containing pin conical joints and paragraphs of the relevant standards, which resulted in the inconsistencies, and offer recommendations that will ensure the quality of the joint following its official purpose. Analysis of the geometric parameters of pin conical joints for the first time allowed to determine the dependence of the height of the pin end protrusion above the surface of the connecting parts and the tolerance for this parameter, as well as to propose mathematical dependences for their determination. The presented dependencies can be used in practice for a reasonable calculation during the design of pin conical joints in pump nodes and in machine-building enterprises where such joints are used. For the first time, the determination of the tolerance for hole size for machining conical reamers is presented, and the formula for calculating this parameter is proposed, which is given in the recommendations for their use in machine building enterprises and products containing pin conical joints.

Project Management in Data Warehouse Implementations: A Literature Review

Project management (PM) is a vital part of any data warehouse (DWH) implementation due to its complexity, time constraints, size, high costs, and importance to business. To help achieve efficient PM, project managers require a source of reference that aggregates the previously acquired body of knowledge (BOK) and presents the discovered findings. Yet, no such resource currently exits. Furthermore, no evaluation of the existing BOK has been made, which obstructs its current understanding and hinders future enhancements in the field. The goal of this paper is to remove these gaps by conducting a systematic review of the literature. The review identified 33 relevant studies. Results show that the current literature mostly covers global considerations and research on DWH requirements analysis techniques and that only a small number of studies were conducted to assist project managers. The review method incorporated two research dimensions used to synthesize, interpret and present the findings: the PMBOK ® Guide ’s PM knowledge areas (PMKAs) and DWH stage. The majority of identified studies pertained to integration management, followed by scope management PMKAs. The biggest research gap was discovered for procurement management PMKA. The project initiation/planning DWH stage is most frequently analyzed in existing studies, followed by requirement analysis and database design. Findings from the identified studies are incorporated into a reference map in order to serve project managers as a reference point for additional guidance in their projects and an agenda for further research is provided for researchers looking to contribute to the field.

3D characterization of nanowire devices with STEM based modes

Advanced semiconductor devices have 3D morphologies with nanometer sized features. Therefore, their structural and chemical characterization requires analysis techniques with high spatial 3D resolution. Through focal integrated differential phase contrast and high angle annular dark field scanning transmission electron microscopy (STEM) depth sectioning are among the techniques that can potentially fulfill these needs. In this work they are applied to Si and Ge nanowire structures with gate all around replacement metal gates. It is shown that with both imaging modes slicing with 2D lattice resolution through the polycrystalline gate stack and the monocrystalline wires is possible, while a resolution in the viewing direction on the order of 5 nm is obtained. Based on fast Fourier transformation analysis the crystal distribution in the gate stack and morphology of the nanowires are analyzed. Similar structures are investigated with combined STEM-energy dispersive spectroscopy 180° tomography on pillar shaped TEM specimens. Comparison of the 3D imaging modes and standard TEM/STEM imaging is discussed.

Technical requirements for translucent structures of schools and kindergartens

The article presents some features of the translucent structures design of schools and kindergartens. The analysis of technical requirements for translucent structures of schools and kindergartens was represented. Based on a review of the typical composition of the premises of schools and kindergartens, it was found that different technical requirements should be established for translucent structures installed in rooms of various functional purposes and operating conditions. It was determined that the existing construction practice doesn’t take into account the differentiation of requirements for translucent structures of various premises of schools and kindergartens, and their design, as a rule, is taken to be the same for the entire construction objects. In future, it leads to disruption of the normal operation of the facility (especially in terms of ensuring normal temperature and humidity conditions and natural lighting of the premises). The features of the replacement of translucent structures in reconstructed schools and kindergartens were considered. It has been revealed that the use of modern types of translucent structures of standard construction (first of all, PVC window units) in the reconstruction leads to a significant decrease in the indicators of natural room lighting. Ways to solve this problem were given. Moreover, perspective directions for future research of the issue under consideration were considered.

Sustainable Infrastructure Design Framework through Integration of Rating Systems and Building Information Modeling

BIM (building information modeling) can be the basis for carrying out various performance analyses. Sustainable infrastructure rating systems are suitable tools for assessing an infrastructure’s environmental performance. It is necessary to integrate them in the design process. The research adopted a thorough literature review to follow the development trends, interviews with professionals from the academia and industry, and a critical analysis of technical requirements for integrating BIM tools and infrastructure sustainability rating systems in the design process. This study propagates a conceptual framework for integrating sustainability rating systems by introducing BIM with a sustainability metric plug-in. The adoption of the proposed solution allows for what-if scenarios to better support the incorporation of sustainability into design decisions and the assessment of sustainability at the design phase of the infrastructure project. The framework is used to refine designs and ensure that sustainable goals are met and to demonstrate compliance with regulatory requirements. This paper concludes that greater emphasis should be placed on supporting technical requirements to facilitate the integration of BIM and sustainability rating systems. It defines the possibility of BIM adoption to influence the sustainable project performance in the infrastructure. This framework could streamline the sustainable design process and lead to more integrated infrastructure delivery.
