Degradation Characteristics of the Optical Constants of PE-LD Film-Covered Greenhouses in an Arid Climate

A. M. Abdel-Ghany, I. M. Al-Helal, P. Picuno, M. F. Cidek, more

International Journal of Thermophysics > 2019 > 40 > 6 > 1-14

This study is to describe the degradation behavior of the optical constants (refractive index $$ \bar{n} $$ n¯ and extinction coefficient $$ \bar{\sigma } $$ σ¯ ) of PE-LD sheets during exposure to an arid climate. Values of $$ \bar{n} $$ n¯ and $$ \bar{\sigma } $$ σ¯ are used to determine the solar radiative properties of any PE-LD cover at any time without the need of measurements. Different...

Effect of Aging on the Spectral Radiative Properties of Plastic Film-Covered Greenhouse under Arid Conditions

A. M. Abdel-Ghany, I. M. Al-Helal, Anil Kumar, A. A. Alsadon, more

International Journal of Thermophysics > 2018 > 39 > 10 > 1-15

Plastic films are widely used to cover greenhouses in arid regions. Unlike predicting the total radiative properties of films, predicting the deterioration behavior of the spectral radiative properties is quite difficult during the service life of the films. These properties should be of great interest for crop morphogenesis studies. This study was to investigate the degradation behavior of spectral...

Design and implementation of discrete PID control applied to Bitumen tank based on new approach of pole placement technique

AR. Hamed, E. M. Shaban, R. R. Darwish, A. M. Abdel ghany

International Journal of Dynamics and Control > 2017 > 5 > 3 > 604-613

This paper develops a novel approach for pole placement method of discrete proportional-integral-derivative (PID) control with industrial application of Bitumen system. The approach utilizes first order discrete-time transfer function (TF) with samples time delay more than unity for tuning the PID compensators, in order to achieve a priori set point of Bitumen mixing temperature. The work also introduces...

Adaptive functional-based neuro-fuzzy PID incremental controller structure

A. A. Fahmy, A. M. Abdel Ghany

Neural Computing and Applications > 2015 > 26 > 6 > 1423-1438

This paper presents an adaptive functional-based neuro-fuzzy PID incremental controller structure that can be tuned either offline or online according to required controller performance. First, differential membership functions are used to represent the fuzzy membership functions of the input–output space of the three-term controller. Second, controller rules are generated based on the discrete proportional,...

Evaluation of human thermal comfort and heat stress in an outdoor urban setting in summer under arid climatic conditions

A. M. Abdel-Ghany, I. M. Al-Helal, M. R. Shady

Environment Protection Engineering > 2014 > Vol. 40, nr 3 > 139--150

Thermal sensation and heat stress potential were evaluated in summer in an outdoor arid environment. Such evaluation had never been made in arid regions. Various scales: the temperaturehumidity index (THI), physiological effective temperature (PET), universal thermal climatic index (UTCI) and standard effective temperature (SET*) were used for the evaluation. RayMan software model was used to estimate...

Ant Colony Optimization based PID for single area load frequency control

M. Omar, M. Soliman, A. M. Abdel Ghany, F. Bendary

2013 5th International Conference on Modelling, Identification and Control (ICMIC) > 119 - 123

2013 5th International Conference on Modelling, Identification and Control (ICMIC)

In this paper a novel Artificial Intelligence technique known as Ant Colony Optimization (ACO) is used for optimal tuning of PID controller for load frequency control. The system proposed here is a single area with reheat thermal system containing nonlinearities represented by Generation Rate Constraint (GRC), dead band and wide range of parameters. Three different cost functions have been suggested...

Gamma rays interaction with bismuth borate glasses doped by transition metal ions

F. H. ElBatal, M. A. Marzouk, A. M. Abdel ghany

Journal of Materials Science > 2011 > 46 > 15 > 5140-5152

Ultraviolet, visible, and infrared spectroscopic measurements have been employed to investigate undoped binary bismuth borate glass (60 mol% Bi₂O₃, 40 mol% B₂O₃) and doped samples with 0.2% 3d transition metal oxides in order to obtain information about the role of all the constituents oxides including the dopants on the measured properties. The undoped sample shows strong extended UV-near visible...
