• Conference Proceeding: Another partitioning tool for vertical fragmentation in distributed databases

  [show abstract] [hide abstract]
  ABSTRACT: In this paper we continue the development of partitioning application presented in [13] using JDBC and SQLJ in the ORACLE DBMS. Both APIs are compared by showing specific characteristics, the advantages of connecting to the database through them. The application will calculate the best partitioning scheme using vertical fragmentation and fragment allocation then obtained, in effective places of network. We use a previously implemented algorithm that calculate the local data and remote data accessing cost, and then get the best fragmentation scheme by selecting the lowest cost.

  ABSTRACT: Distributed databases are an optimal solution to manage important amounts of data. We present an algorithm for replication in distributed databases, in which we improve queries. This algorithm can move information between databases, replicating pieces of data through databases.

  ABSTRACT: Mechanical power transmission by reducing the rotating speed under a constant transmission ratio represents the function of a large group of products known as speed reducers. Cycloid gearing roller (invented by L. Braren), through its qualities, has an important role in modern mechanical transmissions. The difference between numbers of teeth of the cycloid gear roller can be equal to 1 (| Z1 - Z2 |  1), without risk of interference, as a result, can be obtained big gear ratios in accordance with in lower overall dimensions.Thus, this paper presents the modeling and simulation of cycloid curves (epicycloids, respectively hypocycloid), which generates the cycloid gears used a lot in robotics.
