Abstract:

Abstract The research aims to explore the level of students’ conceptual understanding of static fluid. This quantitative descriptive research involves 30 students. The research instrument consisted of 10 reasoning multiple choice questions with reliability is 0.629. Student responses are categorized into five levels of conceptual understanding, which are level 0 (NU), level 1 (SM), level 2 (PU/SM), level 3 (PU), and level 4 (SU). The result shows that most students at level 4 (SU) for the concept of hydrostatic pressure are related to density. Most students at level 3 (PU) for the concept of h

Abstract:

Abstract An object-based verification method for short-term, storm-scale probabilistic forecasts was developed and applied to mesocyclone guidance produced by the experimental Warn-on-Forecast System (WoFS) in 63 cases from 2017 to 2018. The probabilistic mesocyclone guidance was generated by calculating gridscale ensemble probabilities from WoFS forecasts of updraft helicity (UH) in layers 2–5 km (midlevel) and 0–2 km (low-level) above ground level (AGL) aggregated over 60-min periods. The resulting ensemble probability swaths are associated with individual thunderstorms and treated as object

Abstract:

The concepts of floating, flying, and sinking object have been studied since junior high school. However, we still often find students' misconceptions regarding the concept, especially of flying objects, even at the university level. This work aims to propose a clarification of the concept of a flying object in the fluid to be correctly described the condition for the flying object. We used eggs, water, and salt solutions to demonstrate sinking, rising, and floating objects in the fluids. The results showed that when the density of the object is the same as the density of the fluid, the positi

Abstract:

The feeling of control is a fundamental aspect of human experience and accompanies our voluntary actions all the time. However, how the sense of control interacts with wider perception, cognition, and behavior remains poorly understood. This study focused on how controlling an external object influences the allocation of attention. Experiment 1 examined attention to an object that is under a different level of control from the others. Participants searched for a target among multiple distractors on screen. All the distractors were partially under the participant's control (50% control level),

Abstract A model of recognition is described based on cell properties in the ventral cortical stream of visual processing in the primate brain. At a critical intermediate stage in this system, ‘Elaborate’ feature sensitive cells respond selectively to visual features in a way that depends on size (± 1 octave), orientation (± 4 5 °) but does not depend on position within central vision (± 5 °). These features are simple conjunctions of 2-D elements (e.g. a horizontal dark area above a dark smoothly convex area). They can arise either as elements of an object’s surface pattern or as a 3-D compon

Abstract We use the age measurements of 114 old astrophysical objects (OAO) in the redshift range 0 ≲ z ≲ 8 to explore the Hubble tension. The age of the universe at any z is inversely proportional to the Hubble constant, H 0, so requiring the universe to be older than the OAO it contains at any z will lead to an upper limit on H 0. Assuming flat ΛCDM and setting a Gaussian prior on the matter density parameter Ωm = 0.315 ± 0.007 informed by Planck, we obtain a 95% confidence level upper limit of H 0 < 70.6 km s−1 Mpc−1, representing a 2σ tension with the measurement using the local distanc

To avoid these issues and to guarantee the reasonable ranking order, this paper introduces a new additive consistency concept for HFPRs.

The probability of an event is in the range of [0, 1]. In a sample space S, the value of probability determines whether an outcome is true or false. The probability of an event Pr(A) that will never occur = 0. The probability of the event Pr(B) that will certainly occur = 1. This makes both events A and B thus a certainty. Furthermore, the sum of probabilities Pr(E1) + Pr(E2) + … + Pr(En) of a finite set of events in a given sample space S = 1. Conversely, the difference of the sum of two probabilities that will certainly occur is 0. Firstly, this paper discusses Bayes’ theorem, then complemen

Abstract We report a Karl G. Jansky Very Large Array search for redshifted CO(1–0) emission from three H i-absorption-selected galaxies at z ≈ 2, identified earlier in their CO(3–2) or CO(4–3) emission. We detect CO(1–0) emission from DLA B1228-113 at z ≈ 2.1933 and DLA J0918+1636 at z ≈ 2.5848; these are the first detections of CO(1–0) emission in high-z H i-selected galaxies. We obtain high molecular gas masses, M mol ≈ 1011 × (α CO/4.36) M ⊙, for the two objects with CO(1–0) detections, which are a factor of ≈1.5–2 lower than earlier estimates. We determine the excitation of the mid-J CO ro

Abstract:

Concrete is one of the most common construction materials used throughout the world. Concrete consists of three main components: cement, coarse aggregate, and fine aggregate. Coarse aggregate serves as the main structural component in concrete, providing strength and resistance to external loads. Currently, technological advancements in construction are rapidly progressing. Therefore, innovation in concrete production is necessary, one of which is recycled aggregate concrete. The aim of this research is to determine the effect of using granite waste as a partial substitute for coarse aggregate

By using segmentation, the main goal is to be able to maintain the tracking process longer when the object starts to be occluded until it is severely occluded right before it is completely disappeared. Object tracking based on object detection was developed by modifying the Mask R-CNN architecture to process RGBD images. The d

The questions of climate change, which are the most relevant at the present time, cause us to think about life in modern realities. Common anomalies require adaptation and effective solutions to provide comfort. The combined effect of outdoor temperature transitions through 0°C and humidity has a negative impact on the condition of the building and the inside microclimate. Most of the buildings that exist now are designed for climatic parameters that differ significantly from modern ones, so the question of adapting objects requires extra attention.

In the present work, we evaluated the performance of six shape comparison methods, among which three are based on machine learning, to distinguish between 588 multi-domain proteins and to recreate the evolutionary relationships at the protein and sp
