Numerical Study of Vortex Shedding behind a NACA 0009 Hydrofoil

This paper addresses the propeller singing mitigation strategy of implementing an anti-singing edge so that the vortex shedding mechanism causing the excitation at the trailing edge of the propeller blade can be reduced. A Reynolds-Averaged Navier Stokes model with a k-ε turbulence formulation in 2D-flow was used to investigate the problem numerically. Simulations on a NACA 0009 hydrofoil with varying inflow velocity, angle of attack, and bevel angle were done. The content in this paper is a summary of the work done by the author during his MSc Individual Project at University College London (Johannessen, MSc thesis, 2020).

Defining a Successful Project in Sustainable Project Management through Simulation—A Case Study

Modern approaches to project management link project success both to sustainability and with the value delivered to project stakeholders. In the final analysis, it is the satisfaction of the identified stakeholders based on the sustainability principle which decides whether a project is successful or not. The value delivered to appropriate stakeholders has to be incorporated in the earliest phases of the project defining process. Otherwise, it may be too late to introduce changes which would allow the right value to be delivered to the right stakeholders. In this paper, we propose that a simulation is used in the phase of project definition to choose such implementation forms for individual project phases or tasks which would facilitate the delivery of the value expected by the stakeholders. Our approach also supports the process of agreeing (among the stakeholders) on the value expected from the project. We show, using a post-factum real-world project case, that the application of a simulation in the predictive project stage may considerably increase the probability of the project’s success.

Development of an algorithm for the Earth remote sensing data classification using deep machine learning methods for analyzing the geosystem model of the territory

The authors propose their solving the task of improving the accuracy of remote sensing data classification under conditions of labeled data scarcity through using a geosystem approach that involves analyzing the genetic uniformity of various-scale territorially adjacent formations and hierarchical levels. The advantage of the proposed GeoSystemNet model is a great number of freedom degrees, which enables flexible configuration of the model based on the task being solved. Testing the GeoSystemNet model for classifying the EuroSAT set, algorithmically expanded from the perspective of the geosystem approach, showed the possibility of increasing the classification accuracy under the conditions of training data scarcity within 9 %, as well as approaching the accuracy of the deep ResNet50 and GoogleNet models. The authors note that the use of the geosystem approach according to the methodology proposed in the article for solving the above-mentioned problem requires an individual project approach to the formation of the data for analysis.

On Staging Work: How Research Funding Bodies Create Adaptive Coherence in Times of Projectification

While recent science and technology studies literature focuses on “projectification” and its felt tensions for researchers, a surprising scarcity of empirical work addresses experiences at the “other end,” such as funding bodies often held “responsible” for tensions encountered by researchers. Actors in funding bodies experience similar tensions, however. While projectification necessitates predictability and individual project objectives, research funding is also increasingly organized in networks promoting local experimentation. Moreover, funding bodies are part of a system of accountability in which investments are legitimized politically in often reductionist ways. We argue for the salience of more detailed empirical investigations into the work of funding bodies as they navigate these tensions. We apply a dramaturgical perspective to investigate the “staging work” of program committees responsible for the management of funded programs, identifying three forms of staging work: setting the scene, temporal narration, and signifying success. All come with discursive, material, and symbolic dimensions. We develop the notion “adaptive coherence” to show how the program committee sought to maintain the coherence of the overall program despite continuous risks of fragmentation due to projectification, local experimentation, and divergence in interests. “Adaptive coherence” proves productive in incorporating the temporal and spatial dimensions of staging work in networked contexts.

Organization of individual project activities with sports-gifted children

The article discusses the experience of individual project activity organization with gifted children in a summer sports camp, where 64 young athletes of the Republic of Tatarstan participated in pedagogical testing and experiment and were involved in table tennis, wrestling, athletics and showed high performance. The implementation of the individual project for their body self-control proposed by the authors within the framework of the “Champion's Way” educational program implies the creative, research activities of a young athlete, coordinated with the trainer and parents, and contributes to the development of the necessary competencies. The result of individual project activity is a socially important product obtaining - an individual project work “Self-monitoring of physical condition”, in which an athlete describes and analyzes his body in detail, observing his health. The main goal of the project as a young athlete is to learn how to examine himself to improve his athletic performance without compromising his own health. The paper presents specific proposals for project activity organization through a system of laboratory exercises and specialized trainings relevant in the field of physical culture and sports activities and aimed at skill development necessary for health-saving behavior of young athletes and coaches.

Conventional, High-Resolution and Imaging Flow Cytometry: Benchmarking Performance in Characterisation of Extracellular Vesicles

Flow cytometry remains a commonly used methodology due to its ability to characterise multiple parameters on single particles in a high-throughput manner. In order to address limitations with lacking sensitivity of conventional flow cytometry to characterise extracellular vesicles (EVs), novel, highly sensitive platforms, such as high-resolution and imaging flow cytometers, have been developed. We provided comparative benchmarks of a conventional FACS Aria III, a high-resolution Apogee A60 Micro-PLUS and the ImageStream X Mk II imaging flow cytometry platform. Nanospheres were used to systematically characterise the abilities of each platform to detect and quantify populations with different sizes, refractive indices and fluorescence properties, and the repeatability in concentration determinations was reported for each population. We evaluated the ability of the three platforms to detect different EV phenotypes in blood plasma and the intra-day, inter-day and global variabilities in determining EV concentrations. By applying this or similar methodology to characterise methods, researchers would be able to make informed decisions on choice of platforms and thereby be able to match suitable flow cytometry platforms with projects based on the needs of each individual project. This would greatly contribute to improving the robustness and reproducibility of EV studies.

Models of projects portfolio formation in construction business

The paper presents models and methods of projects portfolio formation in the construction business. The company’s strategy success depends on the projects which an organization includes in its portfolio to achieve strategic goals. Nowadays companies often use methods of individual project estimation and selection to include in their portfolio of projects. However, such approach does not consider the effect from an individual project on the whole portfolio financial result and the total risk as well as the specificities of the construction industry portfolio formation. There is usually a set of projects for evaluation and selection and, as a consequence, there are several potential portfolio combinations for a company to choose. Construction business is project-oriented and a correct choice of a certain project and a portfolio with the best combination of projects is a strategically important management element. Models and methods of portfolio formation and management will help to make a choice. The paper presents specific features of portfolio in the construction area which should be considered in the portfolio methodology formation. The comparative analysis of mathematical models for project evaluation and portfolio selection in the construction business was provided. The profiles of companies to implement different models were determined. The results of the research will be useful for scientists and practitioners to choose a model for application or adaption to a company’s needs.
