Waterfall Model

The role of suppliers and customers greatly affect the distribution of basic food that will be realized in distribution scheduling. In addition to suppliers and customers, several factors used in the preparation of scheduling are the location of suppliers and customers, time / period, and the route of the trip that is formed along with the status of the food delivered. The initial step in making an application is needed is to make an analysis and design first. So the model used in this study is a modified Waterfall model. In the analysis section an application needs search is performed to determine the properties of the application to be made, such as management of user access rights and existing facilities and business process modeling using Unfied Modeling Language (UML), namely use case diagrams, activity diagrams, and class diagram. At the design stage it is used to create software blueprints. The things done include database design and application interface. Existing facilities in this application that must be available are login and registration facilities, managing supplier and customer data as well as couriers, ordering groceries, and scheduling the distribution of groceries, as well as the status of food distribution. For further development of this research can implement the design of applications that are made. Moreover, it can determine the method of finding the route with the shortest distance or the route with the fastest time

Games have become one of the most popular activities across cultures and ages. There is ample evidence that supports the benefits of using games for learning and assessment. However, incorporating game activities as part of the curriculum in schools remains limited. Some of the barriers for broader adoption in classrooms is the lack of actionable assessment data, the fact that teachers often do not have a clear sense of how students are interacting with the game, and it is unclear if the gameplay is leading to productive learning. To address this gap, we seek to provide sequence and process mining metrics to teachers that are easily interpretable and actionable. More specifically, we build our work on top of Shadowspect, a three-dimensional geometry game that has been developed to measure geometry skills as well other cognitive and noncognitive skills. We use data from its implementation across schools in the U.S. to implement two sequence and process mining metrics in an interactive dashboard for teachers. The final objective is to facilitate that teachers can understand the sequence of actions and common errors of students using Shadowspect so they can better understand the process, make proper assessment, and conduct personalized interventions when appropriate.

To diagnose scoliosis, the standing radiograph with Cobb’s method is the gold standard for clinical practice. Recently, three-dimensional (3D) ultrasound imaging, which is radiation-free and inexpensive, has been demonstrated to be reliable for the assessment of scoliosis and validated by several groups. A portable 3D ultrasound system for scoliosis assessment is very much demanded, as it can further extend its potential applications for scoliosis screening, diagnosis, monitoring, treatment outcome measurement, and progress prediction. The aim of this study was to investigate the reliability of a newly developed portable 3D ultrasound imaging system, Scolioscan Air, for scoliosis assessment using coronal images it generated. The system was comprised of a handheld probe and tablet PC linking with a USB cable, and the probe further included a palm-sized ultrasound module together with a low-profile optical spatial sensor. A plastic phantom with three different angle structures built-in was used to evaluate the accuracy of measurement by positioning in 10 different orientations. Then, 19 volunteers with scoliosis (13F and 6M; Age: 13.6 ± 3.2 years) with different severity of scoliosis were assessed. Each subject underwent scanning by a commercially available 3D ultrasound imaging system, Scolioscan, and the portable 3D ultrasound imaging system, with the same posture on the same date. The spinal process angles (SPA) were measured in the coronal images formed by both systems and compared with each other. The angle phantom measurement showed the measured angles well agreed with the designed values, 59.7 ± 2.9 vs. 60 degrees, 40.8 ± 1.9 vs. 40 degrees, and 20.9 ± 2.1 vs. 20 degrees. For the subject tests, results demonstrated that there was a very good agreement between the angles obtained by the two systems, with a strong correlation (R2 = 0.78) for the 29 curves measured. The absolute difference between the two data sets was 2.9 ± 1.8 degrees. In addition, there was a small mean difference of 1.2 degrees, and the differences were symmetrically distributed around the mean difference according to the Bland–Altman test. Scolioscan Air was sufficiently comparable to Scolioscan in scoliosis assessment, overcoming the space limitation of Scolioscan and thus providing wider applications. Further studies involving a larger number of subjects are worthwhile to demonstrate its potential clinical values for the management of scoliosis.

Abstract An inverse finite element (FE) algorithm is proposed for sheet forming process simulation. With the inverse finite element analysis (FEA) program developed, a new method for concurrent engineering (CE) design for sheet metal forming product and process is proposed. After the product geometry is defined by using parametric patches, the input models for process simulation can be created without the necessity to define the initial blank and the geometry of tools, thus simplifying the design process and facilitating the designer to look into the formability and quality of the product being designed at preliminary design stage. With resort to a commercially available software, P3/PATRAN, arbitrarily three-dimensional product can be designed for manufacturability for sheet forming process by following the procedures given.

This study aims to assess the implementation of the openness of banking data access policies to improving tax compliance in Indonesia. It cause by the implementation of tax collection using a self-assessment system, thus requiring taxpayer data and information through financial institutions, include banking. Researchers used qualitative descriptive methods. The results of this study are, first, there is support for the implementation of the policy on openness to access to banking data in increasing tax compliance in Indonesia in the form of the issuance of Law Number 9 of 2017 concerning Access to Financial Information. Second, the implementation of banking data disclosure policies to increase tax compliance in Indonesia, including the willingness of target groups to comply with policy outputs, in this case the reporting of customer data by banks to the DGT. Third, the policy of open banking data access does not impede or reduce the number of bank accounts and deposits. Fourth, there are technical obstacles both by the DGT and the banking sector, especially in the first year. Furthermore, there are several inhibiting factors in the implementation of this policy, namely IT factors, and resistance from some circles at the beginning of the emergence of regulations, limited financial resources to process data quickly, so it must be done gradually, in addition to lack of quantity and quality of human resources

Assessment Tasks

Assessment practices need to change in mathematics classrooms that adopt the curriculum standards recommended by the National Council of Teachers of Mathematics (NCTM). An assessment system that focuses on broad learning outcomes, uses tasks that are aligned with instructional practices, involves students actively in the process, and informs teachers' instructional and curricular decisions is recommended. Such an assessment process requires teachers to identify important mathematical ideas, along with performance standards that describe what students must do to demonstrate that those ideas have been learned. Open-ended questions, observations, interviews, pre- and post-assessments, self- and peer-assessments are strategies that can be used to gather evidence of students learning. Documentation strategies are needed to help teachers organize and manage assessment data. NCTM has provided six standards for assessment that teachers can use as guidelines to help them evaluate the appropriateness of assessment tasks.

Cascade Flow

This study aims to design an axial turbine rotor blade and predict the turbine performance at preliminary design stage. Quasi three dimensional method was applied to design including blade to blade flow analysis. The blade profile uses a NACA 0015 airfoil by varying the profile thickness from hub to tip. The profile is divided into eleven segments which has different parameters. The profile was analysed using blade to blade flow/cascade flow analysis called vortex panel method to obtain lift coefficient. The analysis of cascade flow was performed in potential flow and prediction of turbine perfomance is carried out involving common best practice to give drag effect on the blade. The design of the turbine was applied on three different rotors, which also have a different discharge, head, and design rotation. The outer diameter of turbine 1 is 0.65 m, while turbine 2 and turbine 3 have an outer diameter of 0,60 m. The calculation result show that the efficiency of turbines 1, 2, and 3 were 88,32%, 89,67%, and 89,04%, respectively.

This paper presents a method to use the Bezier curve to rapidly generate three-dimensional low-thrust trajectories, which can provide a suitable initial approximation to be used for more accurate trajectory optimal control tools. Two missions, from Earth to Mars and the asteroid Dionysus, are considered to evaluate the performance of the method. In order to verify the advantages of this method, it is compared with the finite Fourier series method. Numerical results show that the Bezier method can get better performance index in shorter computation time compared with the finite Fourier series method. The applicability of the solution obtained by Bezier method is evaluated by introducing the obtained solution into the Gauss pseudospectral method as an initial guess. The simulation results show that the Bezier method can rapidly generate a very suitable three-dimensional initial trajectory for the optimal solver. This is very important for rapid evaluation of the feasibility of a large number of low-thrust flight schemes in the preliminary mission design stage.

A three-dimensional finite element code is used for the eigenvalue analysis of the thermoacoustic combustion instabilities modeled through the Helmholtz equation. A full annular combustion chamber, equipped with several burners, is examined. Spatial distributions for the heat release intensity and for the time delay are used for the linear flame model. Burners, connecting the plenum and the chamber, are modeled by means of the transfer matrix method. The influence of the parameters characterizing the burners and the flame on the stability levels of each mode of the system is investigated. The obtained results show the influence of the 3D distribution of the flame on the modes. Additionally, the results show what types of modes are most likely to yield humming in an annular combustion chamber. The proposed methodology is intended to be a practical tool for the interpretation of the thermoacoustic phenomenon (in terms of modes, frequencies, and stability maps) both in the design stage and in the check stage of gas turbine combustion chambers.
