Abstract:
Graphimages, which represent data structures through nodes and edges, present significant challenges for clustering due to their intricate topological properties. Traditional clustering algorithms, such as K-means and Density-Based Spatial Clustering of Applications with Noise (DBSCAN), often struggle to effectively capture both spatial and structural relationships within graph images. To overcome these limitations, we propose a novel two-stage clustering approach that integrates conventional clustering techniques with graph-based methodologies to enhance both accuracy and efficiency.

ABSTRACT Tomato is one of the most important crops, the worldwide production in 2012 reached 161.8 million tons. Considering the lack of agronomic information on already available cultivars as well as on the varieties under development by breeding programs for organic systems, the objectives of this work were determine the yield components of 14 tomato cultivars in the organic system, through univariate and multivariate analysis. The experimental design was randomized blocks with six replications and five plants per plot. Evaluations consisted of total, marketable and non-marketable yield and

Abstract:
Holter monitoring of electrocardiogram (ECG) is a modern method for assessing the balance of the autonomic nervous system (ANS) and its impact on the activity of the cardiovascular system. Heart rate variability (HRV), as a characteristic of heart rate fluctuations of R-R intervals, reflects the balance of the ANS. The diagnostic value of the method increased by cardiovascular reflex tests, such as orthostatic, breath holding, Valsalva maneuver. Aim - to determine the diagnostic sensitivity and capabilities of functional tests in the process of ECG monitoring to assess the balance of autonomic

Background:The chronic nature of rheumatic diseases has a negative impact in quality of life. Pain and loss of function in the upper extremity cause a progressive difficulty to perform daily activities, often requiring integral physical rehabilitation programs. Anthropometric measurements habitually take prolonged periods of time, given the extensive nature of physical examination in rheumatic patients. It is unknown which factors are most efficient to better reflect the functional status of the rheumatic patient.Objectives:Determine the most efficient anthropometric measurements in the upper

Background. The growing of spring wheat in arid conditions is a difficult task because the biological characteristics of the crop and its demands on moisture reserves. The need for sowing spring wheat in the spring is dictated by the possible death of winter grains in winter. Purpose. To determine the most adaptive varieties of spring wheat with high yield and good quality for cultivation in the dry climate of the Lower Volga region of Russia. Methods. To achieve this goal, an environmental test of spring wheat varieties was carried out by us; the harvest results were processed by analysis of

knowledge is a fluid mixed of experiences, existing information, values, and expert insight, which is acquired by education and experience. Knowledge is classified into two major types, namely explicit and tacit. Unlike explicit knowledge, the tacit knowledge is intuitive and exists in the human brain, and cannot be simply codified and transferred.1Epidemiology is the scientific and systematic study of the occurrence, dispersion, and determinants of health-related conditions in a specific population at a point or period of time in order to manage health issues.

Abstract:
ABSTRACTFreezing of Gait (FOG) is a prevalent symptom in advanced Parkinson's Disease (PD), characterized by intermittent transitions between normal gait and freezing episodes. This study introduces a novel graph‐theoretic approach to detect FOG from video data of PD patients. We construct a sequence of pose graphs that represent the spatial relations and temporal progression of a patient's posture over time. Each graph node corresponds to an estimated joint position, while the edges reflect the anatomical connections and their proximity. We propose a hypothesis testing procedure that deploys

Abstract:
Substantial gains have been made in recent years toward understanding techniques for immersing participants in recreation activities. Immersed participants “become physically (or virtually) a part of the experience itself” (Pine &amp; Gilmore, 2020, p. 40); their actions merge with their awareness (Csikszentmihalyi, 1975). As competition in the leisure and travel industries intensifies, managers and program evaluators will need efficient approaches to measure the ebbs and flows of participants’ immersion during participation. The latest research suggests it is not sufficient to use a single nu

Abstract:
In many industrial experiments, completely randomized designs (CRDs) are impractical due to restrictions on randomization, or the existence of one or more hard-to-change factors. Under these situations, split-plot experiments are more realistic. The two separate randomizations in split-plot experiments lead to different error structure from in CRDs, and hence this affects not only response modeling but also the choice of design. In this dissertation, two graphical tools, three-dimensional variance dispersion graphs (3-D VDGs) and fractions of design space (FDS) plots are adapted for split-plot
