Perancangan Website Promosi Pada PT. Mitra Kerinci Padang

PT. Mitra Kerinci is a tea plantation company that has an office in Padang. Website promotion, especially at PT. Mitra Kerinci Padang does not yet have a website capable of providing information. On the basis of the problems that occur, the author has conducted research to design a promotional information system for PT. Partners of Kerinci Padang. In the process, the output design, input design and file design are designed, which are then implemented into the PHP programming language supported by the MySQL database. With the existence of a promotional website at PT. This Padang Kerinci partner, can provide information that is effective and easily accessible to users.

A Survey On Fragmentation In Distributed Database Systems

One of the most critical aspects of distributed database design and management is fragmentation. If the fragmentation is done properly, we can expect to achieve better throughput from such systems. The primary concern of DBMS design is the fragmentation and allocation of the underlying database. The distribution of data across various sites of computer networks involves making proper fragmentation and placement decisions. The first phase in the process of distributing a database is fragmentation which clusters information into fragments. This process is followed by the allocation phase which distributes, and if necessary, replicates the generated fragments among the nodes of a computer network. The use of data fragmentation to improve performance is not new and commonly appears in file design and optimization literature. An efficient functionality of any distributed database system is highly dependent on its proper design in terms of adopted fragmentation and allocation methods. Fragmentations of large, global databases are performed by dividing the database horizontally, vertically or combination of both. In order to enable the distributed database systems to work efficiently, the fragments have to be allocated across the available sites in such a way that reduces communication cost of data.In this article, we have tried to describe the existing methods of database fragmentation and have an overview of the existing methods. Finally, we conclude with suggestions for using machine learning to solve the overlap problem in fragments.

How to prevent fracture of NiTi files

More certain therapeutic and significantly facilitated solution of everyday endodontic problems are provided by the introduction of NiTi rotary files in endodontic practice and their proper application. However, their widespread use has caused more and more frequent fractures and has become a significant frustrating factor that diminishes their numerous benefits. Torsional stress and cyclic fatigue are the main reasons for the occurrence of a fracture, and the frequency of NiTi file fractures is exactly proportional to the degree of bending of the canal, knowledge of the features of the file, ie. the skill and expertise of the therapist. The most dominant factor for the occurrence of fractures is the dentist who, in addition to manual dexterity, must have a good knowledge of the anatomy of various canal systems and file design in order to make the best choice for each individual case. Properly formed access cavity and knowledge of the working part of NiTi files enable maximum realization of endodontic skills, increased efficiency of intervention and reduced possibility of error during canal instrumentation. The special treatment of NiTi alloy and new solutions related to the design of the working part have significantly increased file flexibility and resistance to cyclic fatigue. Specific design (reduced number of threads, change of conicity, interruption of blade continuity), reduced engagement of file, ie. change of dynamics of movement in the canal (full rotation, reciprocal, eccentric, transaxial), as well as reduced number of processing files, have also significantly influenced the reduction of fracture risks. The aim of this paper was to analyze the most common reasons for the fracture of NiTi files and emphasize measures and factors that can increase their safe use and reduce complications during canal instrumentation.

Influence of Metallurgy and File Design in Micro Crack Formation in Root Canals - An in Vitro Study

Aim and Objectives: This study aims to compare the incidence of dentinal microcracks produced by Max Wire Technology (XP Endo Shaper-single files), Adaptive Pitch (Hero shaper – multiple files) and Controlled Memory (Hyflex – multiple files) files during root canal procedures in single- rooted teeth using a stereomicroscope. Materials and Methods: Sixty four single-rooted mandibular premolars with similar sizes and completed apices were selected. All specimens were decoronated using a diamond- coated bur with water cooling, leaving roots approximately 15 millimeter in length.Silicone impression material was used for covering the external surface of roots to simulate periodontal ligament space, and specimens were then embedded in the alginate impression material.

Research on Lightweight Method of Ancient Building Information Model Based on WebGL

Aiming at the large amount of component data in the 3D dynamic display of the ancient building BIM model, which caused difficulties in information exchange during the protection of the ancient building, a lightweight method of the ancient building BIM model combining with WebGL and IFC standards was proposed. Using WebGL technology to extend the 3D visualization method of BIM models of ancient buildings, providing new technical support for the protection and research of ancient buildings. First define the JSON intermediate file, design the Revit-JSON data interface, make the model support .html and .js format, and improve the visual display method of the web side; use JavaScript to directly call the JSON interactive program of the underlying GPU to improve the web-side rendering effect of the model; Three.js framework realizes the display and interaction of 3D models of ancient buildings on the Web. Taking a typical ancient building as an example to carry out experiments, the method in this paper can reduce the storage volume by more than 70% on the basis of ensuring that the model information is complete, and has a good rendering effect in the browser. The experimental results verify the effectiveness and feasibility of the method.

SISTEM INFORMASI PEMESANAN TIKET KAPAL MENTAWAI FAST KOTA PADANG BERBASIS WEB

ABSTRACT Mentawai Fast is a company engaged in the field of transportation services. The problem is that there is no web-based ship ticket booking information system, ticket purchases are still manual or a passenger must go to the agent to buy tickets and requires a long time. In this system, it starts with analyzing the current system, which is done by output design, input design, file design. The research method used is SDLC (System Devolopment Life Cyle) with stages a). Planning, b) Analysis, c) Designing Systems and Software, d). Implementation, using design tools, namely UML (Unified Modeling Language). With the design of this ordering information system, it is expected to provide maximum service to customers and minimize errors in data processing. The benefits of this ordering information system are expected to improve service to customers and facilitate the transaction process faster and easier.
