Rapid Color Quality Evaluation of Needle-Shaped Green Tea Using Computer Vision System and Machine Learning Models.

Color characteristics are a crucial indicator of green tea quality, particularly in needle-shaped green tea, and are predominantly evaluated through subjective sensory analysis. Thus, the necessity arises for an objective, precise, and efficient assessment methodology. In this study, 885 images from 157 samples, obtained through computer vision technology, were used to predict sensory evaluation results based on the color features of the images. Three machine learning methods, Random Forest (RF), Support Vector Machine (SVM) and Decision Tree-based AdaBoost (DT-AdaBoost), were carried out to construct the color quality evaluation model. Notably, the DT-Adaboost model shows significant potential for application in evaluating tea quality, with a correct discrimination rate (CDR) of 98.50% and a relative percent deviation (RPD) of 14.827 in the 266 samples used to verify the accuracy of the model. This result indicates that the integration of computer vision with machine learning models presents an effective approach for assessing the color quality of needle-shaped green tea.

Healthcare performance analytics based on the novel PDA methodology for assessment of efficiency and perceived quality outcomes: A machine learning approach

Efficient resource allocation in healthcare organizations remains a complex challenge, exacerbated by the intricate data structure and myriad variables involved. While traditional methods like Data Envelopment Analysis have been employed, these often lack the requisite discriminatory power for accurate evaluation. This study introduces the PDA methodology, a fusion of Principal Component Analysis, Data Envelopment Analysis, and Analysis of Variance algorithms, developed in a machine learning environment. To further optimize discriminative power, the Particle Swarm Optimization Algorithm was included. By applying the PDA methodology to hospitals in the Apulia region of Italy, we found that facilities with better perceived quality tend to be more efficient. Furthermore, we identified significant variations in efficiency based on network affiliation and hospital level. Machine learning algorithms, including linear regressions and neural networks, confirmed that our methodology outperforms traditional Data Envelopment Analysis models in precisely distinguishing between varying levels of hospital efficiency. In conclusion, this work provides a fresh perspective for future research and policy decisions in the healthcare domain, demonstrating how the use of advanced and machine learning algorithms can result in more accurate evaluations and targeted interventions.

IMPROVEMENT OF MATHEMATICAL MODELS OF FIBER-OPTIC LINEAR PATH

The article describes the main problem of making a decision about the possibility and effectiveness of the use of fiber-optic communication facilities on communication lines with random parameters. As an example, fiber-optic communication lines of a trusted operator or an adversary are considered. The main reason is indicated, which is the lack of methods that allow predicting the possibility and expediency of using specific fiber-optic communication facilities in given environmental conditions. The necessity of developing and applying a probabilistic mathematical model of a fiber-optic linear path is explained as the basis of the methodology for evaluating the effectiveness of the use of fiber-optic communication means. An analysis of existing mathematical models is given and their shortcomings and imperfections are indicated. A probabilistic mathematical model of the fiber-optic linear path has been developed, which allows calculating the numerical characteristics of the quality indicators of the fiber-optic linear path: Optical Signal-to-Noise-Ratio (OSNR) and Bit Error Ratio (BER), based on the known technical data of the communication means used. The mathematical expectation of a random variable is used as a numerical characteristic, as an idealized average of OSNR and BER. Based on the mathematical expectation, other numerical characteristics are calculated, which are also used when making a decision as a risk measure, and allow us to judge its magnitude and significance. The developed probabilistic mathematical model is proposed as the basis of the efficiency assessment methodology for evaluating the effectiveness of work on communications.

Социально-экономическая эффективность реализации проекта по использованию отвалов вскрышных пород для нужд транспортного строительства на территориях нового освоения

The objective of the paper is to demonstrate a cost efficiency assessment methodology adapted to a major integrated mining and transport project. The sources of social and economic efficiency of the project to use overburden dumps for the needs of transport construction in the areas of new development are stated in the article. In order to assess such a large-scale and complex project, it is not enough to rely on a universal general project methodology; the methods must be adapted and customized. In particular, cross-sectoral and indirect effects arise that will require an adequate organizational and economic scheme for the project to be implemented. It has been concluded that a complex assessment of economic efficiency is only possible with the view of the entire national economy, taking into account not only direct but also indirect, including non-transport, effects. However, the basis for accepting the project for a detailed study is to compare the cost of the ballast material delivered to a specific point in the project network infrastructure of the development territory from the dumps of the mining pits and from the roadside pits, i.e. following the traditional method.

Efficiencya Assessment and Target Setting Using a Fully Fuzzy DEA Approach

Data envelopment analysis (DEA) is a non-parametric methodology for efficiency assessment. This paper proposes a new radial, input-oriented and fully fuzzy DEA approach, based on an LU-fuzzy partial order (L for lower, U for upper), for assessing the relative efficiency of a set of Decision-Making Units (DMUs). The proposed approach involves a radial input contraction, Phase I, and an additive slacks maximization, Phase II. Each phase is first formulated as a fully fuzzy linear programming (FFLP), and then it is transformed into a multiobjective optimization problem. The latter is solved using the lexicographic weighted Tchebycheff method. The proposed fully fuzzy DEA approach provides, for each unit, a fuzzy efficiency measure and a fuzzy target operating point. A classification of the efficiency status of the units is also presented. Computational experiences and comparison with other fuzzy DEA approaches are reported.

Introduction. The development of a clear and understandable strategy for the development of higher education, focused on training, which will be in demand by the modernised economy in the strategic perspective, is one of the conditions for the implementation of the Decree the President of the Russian Federation of 07 May2018. In this regard, the importance of an adequate efficiency assessment of the training system in general and in higher education is growing.Aim. In the context of the initiated discussion on methodological improvement of efficiency assessment of universities, the aims of the present article are the following: to discuss the existing criteria and indicators (proposed by the macro-regulator) of the expertise; to justify the inconsistency of such criteria and indicators to obtain real information on the innovative potential and the quality of human potential of graduates.Methodology and research methods. The research work was carried out on the basis of a systematic approach and inductive research method. To confirm the hypothesis, the method of comparative analysis and the following general scientific methods were applied: analytical review of scientific literature and normative documents, generalisation, comparison and analogy.Results and scientific novelty. Based on the performance monitoring data, the author presents the results of the evaluation of some universities, recognised as centers of innovation, technological and social development of the regions according to the indicators proposed by the Ministry of Education and Science. The conducted analysis indicates the complexity of the formulation of conclusions regarding the innovative potential of universities due to the incorrectness of the approach proposed by the macro-regulator. The shortcomings of the new project proposed by the Ministry of Science and Higher Education to assess the effectiveness of universities and their leaders are revealed. It is necessary to revise the methodology applied. When assessing university efficiency, principle focus should be emphasised on: a) identifying the fact and the dynamics of the increment of knowledge and skills of trainees (primarily, the degree of formation of abilities to learn and independently gain new knowledge); b) assessment of the economic component of the human potential of graduates, involving the introduction of indicators, by which it is possible to judge their demand in the labour market. Three measurement control points are proposed: the level of remuneration at the initial stage of career, in five and ten years after graduation. As a basic indicator of the university innovation activity, it is proposed to consider the share of the profits derived from the use of intellectual activity results in the total income of the organisation. In technical universities, this indicator can be used with additional indicators: number of patents per 100 scientific and pedagogical workers; the number of patents per 100 published articles indexed in the world scientometric databases. In order to maximise the potential of in-service teachers, the principles of financing universities should be changed, as well as the target rates should be introduced to attract young scientific and pedagogical personnel.Practical significance. The research results can be used to improve the methodology for efficiency assessment of universities, as well as to avoid the institutional traps in higher education and science.

Winners in the urban champions league – A performance assessment of Japanese cities by means of dynamic and super-efficient DEA

This paper aims to provide an advanced dynamic efficiency assessment methodology for city performance strategies in Japan, based on an extended and super-efficient Data Envelopment Analysis (DEA). The use of this novel efficiency-improving approach originates from earlier research based on the so-called Distance Friction Minimisation (DFM) method. In the present study we develop a new multi-period model from a blend of a Target-Oriented (TO) DFM model including a dynamic approach. This new model is able to present a more realistic efficiency improvement projection comprising a dynamic system of target-settings to achieve a target improvement level so as to programme more realistic policy actions. The above-mentioned Dynamic TO-DFM model will be applied to and tested for a multi-dimensional efficiency assessment of several large Japanese cities. In this study, we consider due to comparative data limitations, two inputs (population and city budget) and two outputs (GDP and tax revenues). Based on these items, this study assesses the relative economic performance of 16 Japanese big cities by means of the above described, extended super-efficient DEA model. Finally, we present an efficiency improvement programme based on the Dynamic TO-DFM model for enhancing the position of inefficient cites.

Lifetime extension for large offshore wind farms: Is it enough to reassess fatigue for selected design positions?

Fatigue reassessment within the decision process of lifetime extension might be uneconomical when individually performed for each turbine of a large offshore wind farm. This paper analyses the possibilities to extrapolate results from fatigue reassessment of wind turbines at selected design positions to other wind turbines of the wind farm. Five monopile-based turbines placed in a generic offshore wind farm were assessed with integrated aero-hydro-elastic simulations. A fatigue assessment was performed for each out of the five selected turbines using site specific environmental data commonly available during the design process. The results were compared to a fatigue reassessment where environmental data were modified in order to account for changes in environmental conditions during the service lifetime of the wind turbines. Results indicate that an extrapolation is feasible for selected parameters when changes in environmental conditions are small. This is an important step towards an effective and efficient assessment methodology for lifetime extension of offshore wind turbines.

An Efficient Assessment Methodology for the Diagnosis of Neurological Disorders from the Uttered Speech Signal

Automatic regular monitoring of the people with speech dysfunctions and the identification of the diseases has a considerable effect in the civilization. Recent days, researches are going on to find the correlation between the speech dysfunctions and the speech impairments. Many algorithms are there to forecast the sternness of the dysfunction's signs. The dysfunctions are majorly classified into Dysarthria & Apraxia. The goal of this paper is to diagnose the people who are affected by the Dysarthria and Apraxia, the diseases under the category taken into account here are Parkinson's disease, Cerebral Palsy, Aphasia and Throat tumor. The total survey on the voice signals of the subjects was made and the dysponia attributes namely Jitter, Shimmer, Pitch, Entropy, Glottal to Noise Equivalent Ratio, Harmonics to Noise Ratio and Wavelet based Dynamic Mel Frequency Coefficients have been extracted from the recorded speech signals using their respective algorithms. Besides this, the categorization has been done using the Eigen value based Support Vector Machine (SVM) classifier to sort out the subjects. The proposed algorithm attained 97.83% accuracy. We visualize our work as the improvement headed for the advancement of acoustic signal processing for the automated unremitting scrutinizes.

OPERATIONAL EFFICIENCY ASSESSMENT OF PENSION FUND MANAGEMENT COMPANIES

The aim of the research is to assess operational efficiency of pension fund management companies by using dedicated efficiency assessment methodology and analyse implications brought by the efficiency assessment. The efficiency assessment methodology employed is Data Envelopment Analysis ( DEA ). The pension fund management companies subject to operational efficiency assessment are the ones operating in Baltic countries Estonia, Latvia and Lithuania. The general research period is 2009-2013. The operational efficiency within the given research is defined as ability of a pension fund management company to generate profit before interest and taxes (i.e. efficiency model output variable) by using commission and administration expenses (i.e. efficiency model input variables). Because a pension fund management business might be dependent on economies of scale and, to a lesser extent, economies of scope, fund management companies are grouped by using a cluster analysis performed on the basis of assets under management and a share of non-pension fund management revenue in order to improve comparability of efficiency findings. Methods used in the empirical part of the research to process above mentioned data are mathematical programming, including DEA as well as main trend analysis, cluster analysis, development indicators, relative and absolute indicators and other methods. The research outcome is assignment of operational efficiency ranks as well as average indicators for pension fund management companies operating in the chosen Baltic countries during the time period 2009-2013 with subsequent discussion of implications efficiency measurement methodology and other analyses performed bring to findings of the research.

Soil solutions: improving water management across Sydney's public open spaces

With the support and assistance of Sydney Water Corporation (SWC), URS Australia Pty Ltd (URS) have developed an Irrigation and Landscape Efficiency Assessment methodology (ILA) to improve the management of public open space across Sydney. To date over 180 ILAs have been conducted, with a number of key management issues identified. Excessive watering from poor irrigation scheduling practises, low soil water-holding capacity (from shallow or sandy textured soils); and inappropriate location of ornamental plantings are regularly encountered. This paper explores the key issues impacting water management across Sydney's public open spaces, and highlights methods available to rectify these issues and reduce potable water use into the future.
