Comparison of solutions to the task of IT product configuration items early identification using hierarchical clusterization methods

The object of this study is the IT project configuration management process. During the research, the problem of early identification of configuration items (CI) in the information system (IS) of enterprise management was solved. Research in this field is mainly aimed at solving the task of early identification of services and microservices during the refactoring of software systems. The issue of the application of artificial intelligence methods for the detection of CI has not been sufficiently investigated. During the study, the Chameleon hierarchical clustering method was adapted to solve the problem of early identification of CI IS. This method takes into account both the internal similarity and the connectivity of individual functions of the studied IS. The adapted Chameleon method was used when solving the task of early identification of CI in the functional task "Formation and maintenance of an individual plan of a scientific and pedagogical employee of the department". 10 functions and 12 essences of the problem database were considered as the initial CIs. The result of the solution is a dendrogram with all possible options for decomposition of the description of the task architecture into individual CIs. Based on the results, a comparative analysis of the use of Chameleon, DIANA, and AGNES methods for solving the problem of early identification was carried out. According to the criteria "Number of vertices of the dendrogram", "Number of levels of decomposition of the dendrogram", and "Evenness of filling the elements of the dendrogram", the results from using the Chameleon method are the best. Using the research results allows automating the procedure of forming backlogs of IT project implementation teams. This makes it possible to improve the quality of IS development by assigning IS containing similar functions to the same IT project executor

A new configuration for enhanced integration of a battery–ultracapacitor system

The principal shortcoming of the batteries in electric vehicles is their limited specific power. The potential solution is having a hybrid energy storage system (HESS) that integrates the ultracapacitor (high specific energy) with the battery (high specific energy), thus ensuring high specific energy and power. Classically, a bidirectional DC–DC converter integrates the two sources, but the converter introduces a delay during the charging–discharging transition of the ultracapacitor. This work proposes a novel converter topology that interfaces the two sources, eliminating an existing transition delay, providing a fault-tolerant operation in case of a switch failure, and efficiently charging the ultracapacitor. Additionally, an algorithm is presented that facilitates energy sharing between the battery and the ultracapacitor, preventing overloading of the battery and ensuring that the ultracapacitor contributes to the peak load demand. The proposed configuration and energy management algorithm are validated experimentally using a 24V laboratory prototype.

Practical implementation of configuration management in the context of concept ship design – first lessons

The implementation of configuration management (CM) in support of concept design activities at the Products and Proposals department of Damen Naval has put forward a number of challenges that seem to be unique to the shipbuilding industry and the process of concept development therein, that traditional enterprise-level product lifecycle management software and processes are unable to tackle. Information fluidity, an uneven and fast evolving tooling landscape and limited team sizes have driven us to pursue dedicated software implementations in support of CM during concept design. From the first attempts of doing so, we have seen that a number of performance requirements for the software that were completely under the radar are now driving factors for further selection (mostly related to speed and agility of the tool), while some others even impact our way of working and organizational structure as a whole, requiring us to carry system responsibility per discipline, instead of only functional responsibility.

Deploying Cray EX systems with CSM at LANL

SummaryLos Alamos National Laboratory has deployed (over the last year and a half) a pair of Cray Shasta machines—a development testbed named Guaje and and production machine named Chicoma, which will soon comprise the bulk of LANL's open science research computing portfolio. In the process, we have encountered a number of problems and challenges in several realms—authentication and authorization, cluster health management, image management, and configuration management. Both independently and in collaboration with Cray/HPE, we have found solutions and brought the system into stable production. The presentation will discuss the solutions and how they came about, and issues we are working to resolve in the near future.

It increases the overall effectiveness of server administration by reducing difficulties with server management and establishing the groundwork for a strong and resilient digital infrastructure that can adjust to changing cyber security threats

Supporting the digital thread through the principles of complementarity

AbstractTo establish a coherent Digital Thread, encompassing diverse information obtained during the design process, it is imperative to ensure the traceability of information particularly between engineering and manufacturing teams. A challenge lies in maintaining links between data, particularly in the context of configuration management. Through the principles of complementarity, we explore links between the Engineering and the Manufacturing definitions through a major structural element. We forsee the principles of complementarity as a support for Digital Thread throughout the product lifecycle.

Effect of land configuration and nutrient management on greengram (Vigna radiata)

A field experiment was conducted from 2010–11 to 2012–13 during the post-rainy seasons at Navsari, Gujarat to evaluate the effects of land configuration and nutrient management on productivity, quality, nutrient uptake and economics of greengram [Vigna radiata (L.) Wilezek] cultivation. Growth attributes, viz. plant height, branches/ plant and dry-matter accumulation, and yield attributes, viz. pods/plant, seeds/pod and seed index and seed and stover yield of greengram exhibited significantly higher values under raised bed method of planting compared to flat bed. Application of recommended dose of fertilizers (RDF 20 : 40 N:P kg/ha) resulted in markedly higher growth and yield attributes, grain yield, stover yield, N and P uptake, and net returns over the application of 75% RDF. Similarly, an application of FYM at 5 t/ha resulted in higher growth and yield attributes, grain yield and stover yield over no FYM application. Among treatment combinations, raised bed planting + RDF found superior to the other treatments.

Land configuration and nutrient management model increased the productivity through improved soil enzyme activities in an organic cotton wheat production system

Suitable land configuration and nutrient approach are essential for sustaining crop production under semi-arid Inceptisols of India. The study aimed to assess the effect of land configuration (raised bed [RB] and flat bed [FB]) and nutrient approach, viz., organic (Organic), inorganic (soil test crop response [STCR]), and integrated nutrient management (STCR-Integrated plant nutrient supply [IPNS]) along with farm yard manure (FYM) and control (CK) on soil’s physicochemical and biological properties after two consecutive cycles of cotton-wheat. Results showed that land configuration did not impact the pH, organic carbon, and its stock at 0–15 and 15–30 cm soil. However, bulk density was reduced (2.03%) and microbial biomass carbon increased (5.12%) significantly under RB at 0–15 cm soil compared to FB planting. The RB significantly increased the available N (4.06%), P (8.40%) and K (4.22%) and urease (8.37%), alkaline phosphatase (6.10%), and dehydrogenase activity (8.28%) of soils compared to FB. Soil physicochemical and biological properties were highly impacted under STCR-IPNS treatment and least under control at both depths. Integrated treatment showed the highest seed cotton (3097 kg ha−1) and wheat grain yield (6085 kg ha−1); however, land configuration did not impact the yield of both crops. Further, RB increased the protein content of wheat by 1.1% and the ginning percentage and lint index of cotton by 2.4% and 5.5%, respectively compared to FB. In terms of nutrient management, cotton and wheat quality parameters were found higher for STCR-IPNS treatment. Thus, the study suggests that RB planting with an integrated nutrient approach could be a sustainable and feasible practice for quality food and fiber production for semi-arid Inceptisols.

Approach to spatial integration on a novel and complex major project – STEP concept Tokamak

The purpose of this work was to establish an approach to drive the development, at pace, of a commercially relevant Spherical Tokamak Concept. Building on the table of parameters and idealised geometry generated from the work of S. Muldrew et al. [1], applying core principles, tools, and approaches. The generation and utilisation of a reflective 3D Spatial Model to represent the current concept, now forms a strong basis for identifying, evaluating, and delivering future integrated decisions, developed within a 16 Month timeframe.STEP is an ambitious programme, tasked with delivering a prototype plant by 2040 as a pathway to commercial fusion energy. Tackling the integration of a system that itself is based on emergent technologies, significant assumptions (e.g. Plasma Physics) and uncertainties is a significant challenge whilst maintaining acceptable levels of commercial relevance and feasibility. This paper shares the developments and approaches to collaboration and communication taken, including the management of a graphical representation (CAD or Computer Aided Design) to overcome this challenge.The work conducted has resulted in a single point CAD (utilising CATIA software) model representing the current integration status including an appropriate approach to configuration management. Clear channels and methods of communication nurtured a successful collaborative and cross-functional integration approach. Transitioning swiftly from an externally driven approach to integration, to an inherent, self-orchestrating one across all system areas. This paper presents results as a single point Concept Design for the Integrated Tokamak, a strategic management approach, technological integration challenges (e.g. Services, Maintenance, Neutronics) faced, and considerations for the future (post concept design).Introducing a centralised design process, appropriate control and clear communication utilising CAD has been the key to maturing the STEP Tokamak Concept. Initial focus on facilitating collaboration and utilising this environment as a ‘sandbox’ enabled early establishment of a ‘space-claim’ concept design in which to iterate. Staging the integration approach and CAD model fidelity developments through ‘Identification, Realisation and Accommodation’ built a resilient foundation to progress through the full design process. This approach has enabled early identification of not only where the integration challenges lay but also their significance, resulting in strategic deployment of valuable resource.

EXECUTIVE TEAM FAULT LINES AND GREEN INNOVATION PERFORMANCE OF ENTERPRISES - A PERSPECTIVE OF RISK UNDERTAKING

Environmental pollution and ecological degradation are increasingly becoming urgent global issues, drawing widespread attention. Against this backdrop, how businesses can balance economic benefits with environmental protection to ensure sustainable development has become a pressing issue to address. Green innovation, representing a synergistic blend of "innovation-driven" and "green development," can simultaneously meet the requirements for economic growth and ecological environmental protection. In the process of driving green innovation, the executive team plays a crucial role. As the heart of corporate decision-making and execution, the internal differentiation within the executive team, including physiological fault lines based on gender and age as well as task-related fault lines based on education, function, and tenure, affects the team's collaboration and decision-making efficiency, thereby influencing the implementation and outcomes of green innovation. Green innovation projects often entail high risk, difficulty, and long return cycles. 
 When making green innovation decisions, a company's insufficient risk-taking capacity may limit its investment and attempts at green innovation. This study, grounded in upper echelon theory and other theoretical frameworks, selects Chinese manufacturing companies listed from 2015 to 2022 as research subjects. From the perspective of corporate risk-taking, it delves into how physiological and task-related fault lines within the executive team affect green innovation performance by influencing the company's capacity for risk-taking. The research findings indicate that rational configuration and effective risk management by the executive team are crucial for promoting green innovation within a company, offering theoretical and practical guidance for achieving sustainable development.

The Neocolonial Structural Model Re-Foundation and The Pragmatic Inference of Organizational Culture in Ngugi Wa Thiongo’s Devil on The Cross (1980)

Through the frame frequency of the imported state and the westernization of the African political order, the social construction of the African bureaucracy appears as a structural device of abstraction, exploitation, and brutality. Then, through the frame of reference with the importation of conceptual juridical coordination and perceptual representative consensus, the African public administration enhances a frameshift transformation and a succession of causality. Therefore, in combinatorial and transactional analysis, the framework of Devil On The Cross progresses in a method of empirical processing decomposition. Within this respect, the elemental and pure imaginary of the African administration proceeds as a functional derivative governmentality and a colonial functional inception power. Subsequently, with its interaction design, processing system, and volume technique, the realm of Devil On The Cross inserts a paradigmatic analysis and a value engineering within which this African administration happens as an characteristic structural formula and an inefficient relational frame theory. Moreover, within the space-time continuum, the configuration management and the linear configuration programming of the African management apparatus, Devil On The Cross becomes a holomorphic function and an analytic continuation that reveal the anachronism nature and the asynchronous system of the African post-colonial administration.

Effect of soil nutrient management and land configuration on rhizospheric microbial diversity under cotton (Gossypium spp.)-wheat (Triticum aestivum) cropping system in semi-arid region

Microbial diversities in the vicinity of root rhizosphere play a crucial role in promoting plant and soil ecosystem health and productivity. They have great potential as key indicators of soil health in agro-ecosystems enhancing the availability of nutrients. Therefore, a study was carried out during 2019–20 and 2020–21 at research farm of Chaudhary Charan Singh Haryana Agricultural University, Hisar, Haryana to investigate the rhizospheric microbial diversities under cotton (Gossypium spp.)-wheat (Triticum aestivum L.) cropping system as affected by land configuration and nutrient management. Experiment consisted of 5 nutrient treatments replicated thrice and two land configurations, viz. raised bed (RB) and flatbed (FB) planned in factorial randomized block design (RBD). The results of experiment under RB revealed that farmyard manure (FYM) and FYM with biofertilizer and cow urine formulation (FYM + Org) showed the highest bacterial, fungal, phosphate solubilizing bacteria, azotobacter and actinomycetes population (6.92 to 7.51, 24.63 to 26.80, 7.61 to 7.68, 8.74 to 9.15,7.27 to 7.66 cfu/g soil, respectively). The decrease in microbial diversity was observed under inorganic fertilizer application through soil test crop response approach with targeted yield of 5.5 and 2.8 mg/ha (STCR5.5/2.8) and 6.0 and 3.2 mg/ha (STCR6.0/3.2) and control for cotton and wheat, respectively. Higher microbial population and soil organic carbon was found in RB compared to FB. The STCR5.5/2.8 and STCR6.0/3.2 recorded highest cotton and wheat yield followed by FYM and FYM+Org and least in control under cotton-wheat system. Thus, the study suggests that RB planting with an addition of manures along with biofertilizer and cow urine formulation could be a sustainable and feasible practice through enhanced microbial population raising soil fertility leading to increase the crop yields under semi-arid regions.

AN OVERLAPLESS MATURITY MODEL FOR CONFIGURATION MANAGEMENT

IT departments often encounter challenges due to overlapping practices from various frameworks, leading to unnecessary costs and inefficiencies. Additionally, Configuration Management (CM) process-es are frequently implemented poorly, missing out on potential benefits. To address these issues, our research employs a Systematic Literature Review and Design Science Research methodology to develop a comprehensive and non-redundant CM Maturity Model. By integrating frameworks such as COBIT, ITIL, and CMMI-SVC, our model is designed to assist organizations lacking clear improvement strate-gies, those with inadequately implemented CM processes, or those seeking self-assessment. The model is also beneficial for companies managing multiple standards simultaneously. Managers can utilize this model to evaluate CM maturity before implementing various frameworks. Furthermore, we introduce the concept of “Quick Wins” to accelerate improvement initiatives. This research provides a practical tool for IT professionals to streamline CM processes and navigate the complex landscape of IT frameworks, ultimately leading to more efficient and effective CM practices.

MiniDAQ-3: Providing concurrent independent subdetector data-taking on CMS production DAQ resources

The data acquisition (DAQ) of the Compact Muon Solenoid (CMS) experiment at CERN, collects data for events accepted by the Level-1 Trigger from the different detector systems and assembles them in an event builder prior to making them available for further selection in the High Level Trigger, and finally storing the selected events for offline analysis. In addition to the central DAQ providing global acquisition functionality, several separate, so-called “MiniDAQ” setups allow operating independent data acquisition runs using an arbitrary subset of the CMS subdetectors. During Run 2 of the LHC, MiniDAQ setups were running their event builder and High Level Trigger applications on dedicated resources, separate from those used for the central DAQ. This cleanly separated MiniDAQ setups from the central DAQ system, but also meant limited throughput and a fixed number of possible MiniDAQ setups. In Run 3, MiniDAQ-3 setups share production resources with the new central DAQ system, allowing each setup to operate at the maximum Level-1 rate thanks to the reuse of the resources and network bandwidth. Configuration management tools had to be significantly extended to support the synchronization of the DAQ configurations needed for the various setups. We report on the new configuration management features and on the first year of operational experience with the new MiniDAQ-3 system.
