  • Color quality is one of the important criteria in determining the output of a product in the textile industry. However, the color testing process in some current dyeing factories is still largely dependent on human factors. These traditional methods often lead to difficulties and complexity in the operation and management of production information.

  • Plant protection is an important part of crop cultivation, in which chemical method is most effective to control insecticide in comparison to other methods. Chemicals are usually spread on plant through sprayer and duster. Duster is mostly used for dense foliage crops to kill insect using insecticides in form dust powder having particles size (1-10μm). Indian farmers mostly use belly mounted hand rotary duster for dusting. It is traditional method of dusting which have many limitations.

  • In this paper, the authors propose a novel adaptive multilayer T-S fuzzy controller (AMTFC) with a optimize soft computing algorithm for a class of robust control uncertain nonlinear SISO systems. First, a new multilayer T-S fuzzy was created by combined multiple simple T-S fuzzy model with a sum function in the output. The multi-layer fuzzy model used in nonlinear identification has many advantages over conventional fuzzy models, but it cannot be created by the writer's experience or the trial and error method. It can only be created using an optimization algorithm.

  • This paper proposes a Model Predictive Control (MPC) method used for DC-AC converter applications to connect the electrical systems in industry. DC-AC inverters used to convert DC power into AC power for supplying to an AC load. Parameters are controlled in output voltage value or current value, corresponding to voltage source inverter (VSI) inverter and current source inverter (VSC) [1]. DC-AC converter phase three is the main part of the three-phase inverter.

  • This paper presents an investigation on the performance of ZnO nanorod (ZNR)-based piezoelectric nanogenerators (PENGs). ZNRs on the ZnO seed layer coated double-sided flexible polyethylene terephthalate (PET) at different molar concentrations (0.01, 0.05 and 0.1 M) were synthesized by controlling the aspect ratio (length/diameter) of ZNRs, that are closely related to the piezoelectric output potential voltage using a simple hydrothermal method.

  • Customer satisfaction terminology applied in the project problem and solution method has been increasingly important in construction industry. The method presented is using design phase of project life cycle as the study case. The interaction process or input and output method developed is a process of combining a project life cycle and a customer-oriented process. The internal and external customers were introduced to define the strategic objectives and next phase objectives. The method has ascertained the customer requirements through the design phase of project life cycle.

  • The combination of the kernel trick and the least-mean-square (LMS) algorithm provides an interesting sample by sample update for an adaptive equalizer in reproducing Kernel Hilbert Spaces (RKHS), which is named here the KLMS. This paper shows that in the finite training data case, the KLMS algorithm is well-posed in RKHS without the addition of an extra regularization term to penalize solution norms.

  • While construction of the Aswan High Dam (AHD) has stopped concurrent flooding events, River Nile is still subject to low intensity flood waves resulting from controlled release of water from the dam reservoir. Analysis of flow released from New Naga-Hammadi Barrage, which is located at 3460 km downstream AHD indicated an increase in magnitude of flood released from the barrage in the past 10 years. A 2D numerical mobile bed model is utilized to investigate the possible morphological changes in the downstream of Naga-Hammadi Barrage from possible higher flood releases.
