We study the problem of clustering data objects with location uncertainty. In our model, a data object is represented by an uncertainty region over which a probability density function (pdf) is defined. One method to cluster such uncertain objects is to apply the UK-means algorithm [1], an extension of the traditional K-means algorithm, which assigns each object to the cluster whose representat...

Bed shear stress is an important measure of benthic habitats since it related to many ecological processes. In this study, we focused on the fluctuating characteristics in rough-bed open-channel flows. The roughness element method was adopted mimic natural rough beds and Improved Delayed Detached Eddy Simulation (IDDES) model used obtain comprehensive information about near bed. Three arrangeme...

Alat penukar panas merupakan suatu peralatan yang digunakan untuk mempertukarkan energi dalam bentuk antara aliran fluida berbeda suhu dapat terjadi melalui kontak langsung maupun tidak langsung. Salah satu tipe dari alat kalor banyak dipakai adalah Shell and Tube Heat Exchanger. Namun perawatannya kita perlu adanya evaluasi lapangan sebelum dilakukan maintenace. Metode data selama 5(lima) hari...

Due to the remarkable energy savings, isothermal nature of operation and low costs, storage with phase-change materials (PCMs) is a reliable technology for filling gap between supply demand. In this paper, an attempt has been made modify functionality PCM in plate type heat exchanger zigzag configuration. A two-dimensional, time-dependent simulation model phase transition during charging discha...

Sequential combustion architectures rely on auto-ignition flame stabilization in the second stage combustor. Due to exponential temperature dependence of ignition delay time flames can respond hot spots generated by unsteady first combustion. In this paper, response is investigated extending an existing analytical model for acoustic waves so that it also accounts entropy waves. Explicit express...

The primary requirement in designing air conditioning systems healthcare facilities is eliminating contaminants. It considered one of the crucial health elements building design, particularly presence many airborne diseases such as COVID-19. purpose this numerical research to simulate various ventilation designs for a hospital room model by taking into account results obtained previous research...

This study reports the three-dimensional (3D) flow of Ag-MgO hybrid nanofluid (HNF) over a spinning disc flexible thickness in presence modified Fourier law. The HNF is contained silver and magnetic nanoparticulate base fluid engine oil. energy transition has been examined involvement melting heat propagation. highly nonlinear system partial differential equations (PDEs) processed by adopting p...

Abstract The acting on the planing hull is most complex hydrodynamics simulation. Therefore, an analysis was done to evaluate drag, lift force, and seakeeping in two degrees of freedom (2-DOF) which heave trim. It fundamental aspects overall high-speed vessel. This article focused hydrodynamic performance a complete interceptor configuration that could control motion behavior deep-V calm water ...

The heat convection phenomenon has been investigated numerically (mathematically) for a channel located horizontally and partially heated at uniform flux with forced free convection. horizontal fluid inlet the enclosure was exposed to source from bottom while upper side kept constant temperature equal outlet temperature. Transient, laminar, incompressible mixed convective flow is assumed within...
