ڈاکٹر سلامت اﷲ
مشہور ممتاز ماہر تعلیم ڈاکٹر سلامت اﷲ کا انتقال ۹۰ برس کی عمر میں ۲۳؍ جنوری ۲۰۰۲ء کو دہلی میں ہوا اور جامعہ ملیہ اسلامیہ کے قبرستان میں تدفین ہوئی، جامعہ سے عمر بھر ان کا گہرا تعلق رہا، وہ اس کے شعبہ تعلیم (استادوں کے مدرسہ) کے معماروں اور قومی سطح کے ماہرین تعلیم میں تھے۔ رسالہ جامعہ کے شعبہ ادارت سے منسلک تھے اور اس میں ان کے مضامین بھی چھپتے تھے، انہوں نے اردو اور انگریزی میں متعدد کتابیں لکھیں جن میں تعلیم اور اس کا سماجی پس منظر، تعلیم، فلسفہ تعلیم اور سماج، بنیادی استاد کے لئے، ہم کیسے پڑھائیں: Education of Muslims in thought or Basic اور Secular India can Education do it Education وغیرہ قابل ذکر ہیں، وہ عمر بھر علمی و تعلیمی خدمت میں مصروف رہے، ان کی وفات علمی و تعلیمی دنیا کا بڑا حادثہ ہے، اﷲ تعالیٰ ان کی مغفرت فرمائے، آمین!!

The purpose of this paper is to guide about the main reason of clashes between revealed religions in the society. We do not clarify our vision regarding religion. People do not know about the basic ethics of our religions. So, it creates moral illness in the society. We have narrow approaches about religion and took it in very conservative thoughts. For getting out of extreme level of destruction and moral degradation it is necessary to build a universal society which consists of those social values which are common in all religions. People are inclined towards ills and far away from God that is why our society is a victim of destruction. These ills made them to go far away from God and religion. In the present era the situation is the same, people do not understand the religion properly. Only through this proper understanding, destruction, prejudice, extremism and cruelty can be removed from the society. All the religions have some common features as justice, honesty, courtesy, patience etc these features are the ethical as well as religious codes of a society and if all people follow these features an ideal society can be established. This study covers revealed religions all around the world.
This PhD dissertation reports design and analysis of Micro-Electro-Mechanical system (MEMS) based displacement amplification mechanism. The proposed displacement amplification mechanism has been designed and tested in three different configurations giving experimental amplification factors of 7.6, 16 and 16.14 respectively. The mechanism has been analytically modeled using kinematic and Direct Force Displacement Method. Numerical simulations are carried out by writing a code using MATLAB. Results are found in good agreement with that of the simulated results using FEM based software IntelliSuite® and experimental results substantiating the viability of this displacement amplification mechanism. Parametric analysis of the proposed mechanism evaluated the effect of different geometric parameters, hence finalizing the design geometry. The analysis predicts that length and the angle of flexure are the two key geometric parameters that significantly affect amplification factor and have direct relationship with length and inverse relationship with angle of micro-flexure. Natural frequencies and associated mode shapes of all three configurations of mechanism during free vibrations have been determined from modal analysis. Polysilicon based Multi-User MEMS Processes (PolyMUMPs) has been used for the fabrication of all micro displacement amplification mechanism prototypes. A micro mechanical probe station equipped with tungsten and acupuncture needles has been used to test the functionality of prototypes. The amplification mechanism can be incorporated with micro gripers for increasing displacement at jaw tip. Design and analysis of a variant of displacement amplification mechanism consisting of two configurations of designed amplification mechanisms having experimental amplification factor of 5.8 has been proposed. Thermal and static analysis simulations of configuration 3 of the designed displacement amplification mechanism incorporated with thermal chevron actuator and electrostatic comb drives have been carried out and results discussed in detail at the end.
