The relationships between mean terminal velocity and volume diameter of different hydrometeors, as well how they change with background aerosol concentrations have been investigated numerical simulations tropical deep convection from the Weather Forecast Research Model (WRF), coupled spectral bin microphysics. results showed a positive correlation either mass-weighted (Vm) or number-weighted (V...

In this study, a white light particle image velocimetry (WL PIV) system which employs a light sheet generated with a flash was used. The system was developed in order to provide a cost-efficient and safe alternative to laser systems while keeping the accuracy limits required for hydraulic model tests. To investigate the accuracy of WL PIV method under different flow conditions, experiments were...

The simplest water diversion method in irrigation systems is using intakes. Measuring the mean velocity is one of the essential hydraulic parameters in increasing the efficiency of the intake. In this study, the mean velocity was predicted for different width ratios of an intake using ANN-MLP neural network model. In order to do that, the flow field within a 90-degree intake was first simulated...

In order to create more comfortable and energy saving living spaces, we have to investigate what is comfortable and how to measure comfort of users in a living space. Some measures of thermal comfort have been defined as Predicted Mean Vote (PMV) and Predicted Percentage Dissatisfied (PPD) as an international standard. However, complex and high cost equipments are required to measure PMV by con...

In this paper, we describe a Continuously Adaptive Mean Shift (CAMshift) algorithm with a Kalman filter. A CAMshift algorithm does not consider an object’s direction vectors and velocity. In addition, sometimes, CAMshift loses the tracked object when the color of the background is similar to that of the object. However, using a Kalman filter with the CAMshift algorithm can overcome these disadv...
