PENGARUH PENGEMBANGAN APLIKASI PEMETAAN VISUAL DAN PENCATATAN PELANGGAN TERHADAP PRODUKTIVITAS PENAGIHAN PADA PT.TELEKOMUNIKASI INDONESIA

The writing of this paper aims to present visual mapping applications as an alternative to reduce billing productivity in PT. Indonesian Telecommunications. As for the background of this writing trying to find solutions to address constraints are not found that occur in the field. This is due to the increasing number of customers who use the internet in the region, especially Jakarta, in this case many customers who do not understand about the procedures of payment, due bills and internet disconnection, then there is a lot of arrears so that it becomes the duty of CTB (Caring Teritory Base) as the billing party, then it becomes a problem if the customer's address is incomplete, there is no information rt and rw , the name of the tower, as well as the floor of the building. It will be a concern for the company to reduce Revenue Loss due to unpaid bills, as well as not achieving the targets set by management to employees. The analysis method used by the author is Object Oriented Analysis. (OOA). OOA sees problems based on system user objects. With OOA can be created modeling system. The application of OOA in this study uses Unified Modelling Language (UML) diagram. The Unified Modelling Language (UML) diagrams that the authors use are the Use Case Diagram design of the Activity Diagram design, the Sequence Diagram design, and the Class Diagram design. Application development method or Software Development Life Cycle (SDLC) that the author applied is waterfall method. Waterfall method has a special feature that is the entire development process is carried out in sequence starting from the stage of concept planning, modeling, development, testing and maintenance of the system. This analysis found that the existence of Find&Go application can help in overcoming arrears problems that occur in the company.

Image Schemas and Conceptual Blending in Diagrammatic Reasoning: The Case of Hasse Diagrams

In this work, we propose a formal, computational model of the sense-making of diagrams by using the theories of image schemas and conceptual blending, stemming from cognitive linguistics. We illustrate our model here for the case of a Hasse diagram, using typed first-order logic to formalise the image schemas and to represent the geometry of a diagram. The latter additionally requires the use of some qualitative spatial reasoning formalisms. We show that, by blending image schemas with the geometrical configuration of a diagram, we can formally describe the way our cognition structures the understanding of, and the reasoning with, diagrams. In addition to a theoretical interest for diagrammatic reasoning, we also briefly discuss the cognitive underpinnings of good practice in diagram design, which are important for fields such as human-computer interaction and data visualization.

A Tool for Evaluating the Performance of SiC-Based Bidirectional Battery Chargers for Automotive Applications

In this paper, a procedure to simulate an electronic power converter for control design and optimization purposes is proposed. For the addressed application, the converter uses SiC-MOSFET technology in bidirectional battery chargers composed of two power stages. The first stage consists of a single-phase AC/DC power factor correction synchronous rectifier. The following stage is a DC/DC dual active bridge. The converter has been modulated using a phase-shift technique which is able to manage bidirectional power flows. The development of a model-based simulation approach is essential to simplify the different design phases. Moreover, it is also important for the final validation of the control algorithm. A suitable tool consisting of a system-level simulation environment has been adopted. The tool is based on a block diagram design method accomplished using the Simulink toolbox in MATLAB™.

An Automated Method to Generate and Evaluate Geochemical Tectonic Discrimination Diagrams Based on Topological Theory

Discrimination diagrams can be used to distinguish different tectonic settings of igneous rocks. To improve the quality and efficiency of the design of discrimination diagrams, an automatic design and assessment method for discrimination diagrams is proposed based on topology theory. The method is aimed at programming the traditional process of discrimination diagram design, enabling computers to simulate the visual discrimination process. It thus automatically designs tectonic setting discrimination diagrams by investigating all possible combinations of geochemical elements. In the experiment, analyses of 3803 gabbro samples were collected from three tectonic settings, including island arc, ocean island, and mid-oceanic ridge. Using the proposed method, we found thousands of discrimination diagrams with fields overlapping less than 10%. By analyzing these diagrams, the most critical elements (or element ratio pairs) are identified. Based on the result, the feasibility of using gabbroic rocks to discriminate between tectonic settings is illustrated and four representative discrimination diagrams, including the La/Y–Nb/Ba diagram, Nb/Sc–Sc/Ba diagram, Ba/Nb–Ba/Sc diagram, and La/Na2O–Nb/Ba diagram, are recommended for use. This research supports the view that gabbroic rocks can also be used to discriminate between different tectonic settings. The method could also be applied to other rock types.
