Autism is a neural development disorder characterized by the deterioration in social interacttion, abnormal language expression, repetitive actions, imaginative game tendencies, and limited and/or obsessiveness in certain activities/ interests. Lack of sleep is one of the factors contributing to the worsening of overall negative symptoms of autistic children. From the Islamic perspective, sleep is a necessity and could function as a treatment for health problems, in addition to influencing behavior patterns. Sound therapy has been used in dealing with various health problems, including sleep problems and mental ill health. Possibly, it can also address sleep problems of the autistic children. Listening to the melodious Qur’anic recitation is known to have therapeutic effects even on individuals who do not understand the meaning of the verses being read;it could function as sound therapy. However, no established work has been done to study the effect of Qur’anic verses recitation on autistic children and their sleep problems. Similar to the use of music therapy, Qur’anic recitation is also expected to have a positive impact on speech, learning and interpersonal relationship. As a healing medium, Qur’anic therapy is also expected to have a better result as compared to other conventional sound therapy since its content could be psychotherapeutic.

Improved NCTF Control Method for a Two-Mass Rotary Positioning Systems

引用

Intelligent Control and Automation 2011年第4期2卷 351-363页

作者： mohd Fitri mohd yakub B. A. Aminudin 不详

This paper describes an improvement of the existing nominal characteristic trajectory following (NCTF) as a practical control method for a two-mass rotary point-to-point (PTP) positioning systems. Generally, the NCTF controller consists of a nominal characteristic trajectory (NCT) and a PI compensator. A notch filter is added as a part of the compensator to eliminate the vibration due to the mechanical resonance of the plant. The objective of the NCTF controller is to make the object motion follow the NCT and end at its origin. The NCTF controller is designed based on a simple open-loop experiment of the object. The parameters identification and an exact model of the plant are not necessary for controller design. The performance response of improved NCTF controller is evaluated and discussed based on results of simulation. The effect of the design parameters on the robustness of the NCTF controller to inertia and friction variations is evaluated and compared with conventional PID controller. The results show that the improved NCTF controller has a better positioning performance and is much more robust than the PID controller.

Repercussions of solar high energy protons on ozone layer during super storms

引用

Research in Astronomy and Astrophysics 2019年第1期19卷 21-28页

作者： Asheesh Bhargawa mohd yakub Ashok Kumar Singh Department of Physics University of Lucknow

We are very aware of the importance of the ozone layer, without which life on the Earth would not have evolved in the way it has. Solar storms carry energetic protons into the Earth's upper atmosphere,where they boost production of nitrogen oxides which are known as ozone killers and which ultimately increase ultraviolet(UV) radiations. In the present study, we estimate the effects of solar energetic protons during super storms(Dst index <-300 nT) over the total ozone column for the last 32 yr. We select a total of seven super storm events that occurred during solar cycles 22–24(for the last 32 yr) having Dst index <-300 nT. To that end, we apply superposed epoch analysis(SEA) to verify the impact of storm events on the quantitative variation of total ozone column and on UV radiations during super storm *** completing the empirical analysis, we conclude that the ozone column gets depleted significantly(22±6.8%) as proton density increases during super storm events and this decrement in the ozone level is further responsible for a substantial increase(26±11.2%) in peak UV radiation intensities.
