In this study, we aimed to assess the value of genotyping DNA pools as a strategy to generate accurate and cost-effective genomic estimated breeding values (GEBV) of sires in multi-sire mating systems. In order to do that, we used phenotypic records of 2,436 Australian Angus cattle from 174 sires, including yearling weight (YWT; N = 1,589 records), coat score (COAT; N = 2,026 records), and Meat Standards Australia marbling score (MARB; N = 1,304 records). Phenotypes were adjusted for fixed effects and age at measurement and pools of 2, 5, 10, 15, 20, and 25 animals were explored. Pools were created either by phenotype or at random. When pools were created at random, 10 replicates were examined to provide a measure of sampling variation. The relative accuracy of each pooling strategy was measured by the Pearson correlation coefficient between the sire's GEBV with pooled progeny and the GEBV using individually genotyped progeny. Random pools allow the computation of sire GEBV that are, on average, moderately correlated (i.e., r > 0.5 at pool sizes [PS] ≤ 10) with those obtained without pooling. However, for pools assigned at random, the difference between the best and the worst relative accuracy obtained out of the 10 replicates was as high as 0.41 for YWT, 0.36 for COAT, and 0.61 for MARB. This uncertainty associated with the relative accuracy of GEBV makes randomly assigning animals to pools an unreliable approach. In contrast, pooling by phenotype allowed the estimation of sires' GEBV with a relative accuracy ≥ 0.9 at PS < 10 for all three phenotypes. Moreover, even with larger PS, the lowest relative accuracy obtained was 0.88 (YWT, PS = 20). In agreement with results using simulated data, we conclude that pooling by phenotype is a robust approach to implementing genomic evaluation using commercial herd data, and PS larger than 10 individuals can be considered.

A numerical study of natural convective heat transfer from an upward facing, heated horizontal isothermal surface imbedded in a large flat adiabatic surface has been undertaken. On the heated surface is a series of triangular shaped waves. Laminar, transitional, and turbulent flow conditions have been considered. The flow has been assumed to be two-dimensional and steady. The fluid properties have been assumed constant except for the density change with temperature giving rise to the buoyancy forces. This was with treated using the Boussinesq approach. The numerical solution has been obtained using the commercial CFD solver ANSYS FLUENT©. The k-epsilon turbulence model with full account being taken of buoyancy force effects has been employed. The heat transfer rate from the heated surface expressed in terms of a Nusselt number is dependent on the Rayleigh number, the number of waves, the height of the waves relative to the width of the heated surface, and the Prandtl number. This study obtained results for a Prandtl number of 0.74 which is effectively the value for air. An investigation of the effect of the Rayleigh number, the dimensionless height of the surface waves, and the number of surface waves on the Nusselt number has been undertaken.

Robotic task planning in real-world environments requires not only object recognition but also a nuanced understanding of spatial relationships between objects. We present a spatial-relationship-aware dataset of nearly 1,000 robot-acquired indoor images, annotated with object attributes, positions, and detailed spatial relationships. Captured using a Boston Dynamics Spot robot and labelled with a custom annotation tool, the dataset reflects complex scenarios with similar or identical objects and intricate spatial arrangements. We benchmark six state-of-the-art scene-graph generation models on this dataset, analysing their inference speed and relational accuracy. Our results highlight significant differences in model performance and demonstrate that integrating explicit spatial relationships into foundation models, such as ChatGPT 4o, substantially improves their ability to generate executable, spatially-aware plans for robotics. The dataset and annotation tool are publicly available at https://github.com/PengPaulWang/SpatialAwareRobotDataset, supporting further research in spatial reasoning for robotics.

The four-spacecraft Cluster mission was to be the first to attempt to measure space plasma gradients in three dimensions. The required accuracy of these gradient measurements poses a unique challenge to the accuracy with which the individual measurements must be carried out. In designing the electron analyzers of the PEACE(Plasma Electron And Current Experiment) instrument a design target of 1% relative accuracy between the eight electron analyzers, two on each spacecraft was set. These analyzers are of the Top Hat type of hemispherical electrostatic energy analyzer with a potential 360° field of view. To optimize the analyzer electron optics and investigate the required accuracy of fabrication it was necessary to develop a new computer simulation package. A full 3D simulation was needed to study the effects of finite manufacturing tolerances since they are not in general symmetric. Also in order to meet the scientific requirements for the performance of the analyzer it was necessary to study design parameters outside the range covered by the initial study of such analyzers by Carlson et al (1983). To achieve the accuracy with a practical use of computing time required the development of a faster computational method which is described. The comparison with laboratory calibration data shows that the desired accuracy has been achieved both in the simulation method and in the relative accuracy of the analyzers.

Moisture excess in granular pavement layers can decrease pavement performance leading to moisture-related distresses. The combination of trapped water and heavy traffic loads may substantially increase pore pressure and lead to shear failure if layer hydraulic conductivity is insufficient. Currently, most pavement analysis models are unable to predict pore pressure development, so the design and evaluation methods ignore this dynamic effect which may significantly underestimate the moisture damaging effect on pavements. This paper proposes the use of Biot’s poroelasticity theory for modelling fully saturated unbound materials. The proposed methodology – Poroelastodynamic Finite Integration Technique (PEFIT) – was used to analyze axisymmetric multilayered pavement structures consisting of elastic and poroelastic layers. The model was verified and validated using a well-known commercial finite element solver and field pore pressure data, respectively. A sensitivity analysis was conducted by varying critical pavement design parameters. The PEFIT analysis of a three-layer pavement system with a poroelastic base layer has shown that a decrease in base hydraulic conductivity significantly increases the maximum pore pressure, especially for high-speed loads. Results also indicate substantial pore pressure and water movement in the base layer, which may induce a potential shear failure mechanism for unbound materials.

Fixed asset management is a crucial component in supporting the performance of local governments. However, the Polewali Mandar Regency Government still faces obstacles in managing assets conventionally, such as the risk of recording errors, duplicate data, and difficulties in field data verification which is time-consuming. This study aims to design and build a Web-Based Fixed Asset Management Information System integrated with Quick Response Code (QR Code) technology as a digital solution for real-time asset data collection, tracking, and monitoring. The approach taken for system development is known as the Waterfall approach, encompassing the phases of analyzing requirements, system design, execution, evaluation, and ongoing support. The creation of the system was carried out utilizing the PHP coding language, the MySQL database system, and Tailwind CSS to achieve a mobile-friendly interface. Data collection techniques were conducted through observation, interviews, and literature studies at the General Affairs Division of the Regional Secretariat of Polewali Mandar Regency. The result of this research is a fixed asset management information system featuring the generation of unique QR Code labels for each asset, category and location management, and reporting features divided into three access levels: Admin, Operator, and Verificator. Based on the system testing results, an average score of above 4.00 was obtained for indicators of ease of use (user-friendly), access speed, and information accuracy. In conclusion, the implementation of this QR Code-based system is proven to increase the efficiency of the asset identification process in the field, minimize manual input errors, and improve accountability in regional asset management in Polewali Mandar Regency.

Advances in technology have changed people's shopping patterns, including the use of instant messaging applications such as WhatsApp as a means of transaction. AB-Mart Buyut minimarket has adopted a shopping system via WhatsApp to facilitate consumers in shopping without having to come directly to the store. This study aims to analyze the level of consumer satisfaction with the shopping system via WhatsApp implemented in the minimarket. This study uses a quantitative method by distributing a sample questionnaire of 80 consumers who have used shopping services via WhatsApp with various characteristics of the respondent's profile. The data obtained was analyzed using the SPPSS 26 windows application by testing validity, reliability test, determination test (r2), simple regression analysis test and partial test (t test) to measure the influence of factors such as service quality, ease of use, response speed, and order accuracy on customer satisfaction. The results showed that the shopping system via WhatsApp at AB-Mart Buyut Minimarket has a significant influence on customer satisfaction, with an R Square value of 0.871, which means that 87.1% of customer satisfaction is influenced by the variables studied, while the remaining 12.9% is influenced by other factors not examined in this study. The factors that have the most influence on customer satisfaction are speed of response and order accuracy. Based on these findings, it is recommended that AB-Mart Buyut Minimarket improve service quality by speeding up the response process, improving product information clarity, and ensuring accuracy in order fulfillment. Thus, the shopping system via WhatsApp can be more optimal in increasing customer satisfaction and business competitiveness.

Various algorithms have been proposed for determining the near-surface dielectric function εo of depositing materials from kinetic complex reflectometric or ellipsometric data, even under conditions where the underlying sample structure is unknown. These capabilities are essential for sample-driven closed-loop feedback control of epitaxy, since they allow compositional fluctuations to be detected over nominally vanishingly small thicknesses without the instability inherent in conventional Fresnel analysis. The accuracy of earlier derivative approaches was improved significantly with the development of virtual-interface (V-I) theory, which is based on exact equations instead of exponential-spiral approximations that are valid only for optically thick films. I summarize previous relevant work, assess the accuracy of these derivative methods analytically for the complex normal-incidence reflectance, develop new algorithms by combining earlier approaches, develop a geometric construction that allows relative sensitivities, accuracies, and applicabilities of these algorithms for determining the composition of ternary alloys to be conveniently assessed, and propose a new hybrid V-I–Fresnel method that retains the stability of the V-I approach yet is exact. For ellipsometry the virtual-substrate approximation still represents the best combination of simplicity, speed, and acceptable accuracy.

We study the prospects to measure the CP-sensitive triple-product asymmetries in neutralino production e+e- -> ~chi^0_i ~chi^0_1 and subsequent leptonic two-body decays ~chi^0_i -> ~l_R l, ~l_R -> ~chi^0_1 l, for l=e, mu, within the Minimal Supersymmetric Standard Model. We include a full detector simulation of the International Large Detector for the International Linear Collider. The simulation was performed at a center-of-mass energy of sqrt{s}=500 GeV, including the relevant Standard Model background processes, a realistic beam energy spectrum, beam backgrounds and a beam polarization of 80% and -60% for the electron and positron beams, respectively. In order to effectively disentangle different signal samples and reduce SM and SUSY backgrounds we apply a method of kinematic reconstruction. Assuming an integrated luminosity of 500 fb^-1 collected by the experiment and the performance of the current ILD detector, we arrive at a relative measurement accuracy of 10% for the CP-sensitive asymmetry in our scenario. We demonstrate that our method of signal selection using kinematic reconstruction can be applied to a broad class of scenarios and it allows disentangling processes with similar kinematic properties.

A flying wing possesses no definite fuselage and no horizontal tail surfaces resulting in lesser drag surfaces, a larger wing area with a better range and endurance as compared to a conventional unmanned aerial vehicle (UAV). The present work explores an efficient and stable flight of a flying wing UAV at a lower Reynolds number using backward facing step wing profile. Numerical simulations for flow over a wing with NACA0012 airfoil, having a backward facing step along the length of its chord, on its upper surface were performed. The depth of the step was also varied to find out an optimum depth of the step to improve its aerodynamic performance. This work involves two-dimensional and three-dimensional steady state and transient simulations followed by the introduction of the wing end-plates to control the wingtip vortices. Here, the wings were designed, based on their aspect- and taper-ratios. Structural analysis was carried out to investigate the natural modes and frequencies in the current wing configurations.

A FACTOR which plays an important role in the -*• *design of the horizontal tail surfaces of an airplane is the effect of the ground upon the pitching moment in the landing condition. An airplane capable of being trimmed at all attitudes in the air often cannot be landed in the three-point position because of insufficient elevator control near the ground. In an attempt to obtain quantitative measurements of this phenomenon, and to investigate the adequacy of control of certain proposed airplane designs, the experiments described herein were performed in the ten-foot wind tunnel of the GALCIT. In these tests the ground was represented by a smooth flat plate fixed in the tunnel. It is believed that this method of representing the ground, although not exact because of the presence of the boundary layer on the plate, is sufficiently precise to give value to the results. A considerable amount of experimental data regarding the effects of the ground plate upon lift and drag was obtained incidentally to these investigations. Some of these data are presented in Sections IV and V.

The advent of powerful microcomputers has dramatically affected the operation of the small architectural office. Architects with PC computers now have access to sophisticated CAD, database, specification and analysis programs. Solar energy simulation programs which formerly ran only on expensive main frame and mini computers have been ported over to the new microcomputers. The architect now has a wide range of solar energy analysis tools from which to choose. This report presents the results of evaluations of a number of solar energy analysis tools. The basis for evaluation is described briefly below. To make an informed choice when picking a solar energy analysis tool, the architect needs to know how the tool can fit into the design process; the ease of use of the tool; and the relative accuracy of the tool. The tools evaluated for this research study include complex building energy simulation programs, simplified building energy analysis programs. Programs which model building components related to solar performance, for example, WINDOWS which evaluates the thermal and optical properties of a variety of glazing options. This research project has been divided into two evaluation components. First, the operation and relative accuracy of the solar design tools is evaluated. A fractional factorial experimental method is developed to permit estimate of the effects of 8 building design variables on heating and cooling load requirements. The effects of building design variables estimated by each program are compared and discussed, giving a relative comparison of a solar design tool's accuracy. Second, the program are compared in terms of their applicability to an architectural office. This comparison discusses the applicability of each tool various phases of the design process. The complexity of the program and required skill of the user is also discussed.
