غزل

 

نہ خط لکھوں نہ زبانی کلام تجھ سے رہے
رہے بس اتنا شناسائی کا بھرم باقی
نہ عہدِ ترکِ تعلق، نہ قربتیں پیہم
یہی رہیں ترے نشتر، ترا طریق علاج
نظر میں عکس فشاں ہو ترے جمال کی دھوپ
اب اس سے بڑھ کے مجھے چاہیے بھی کیا آخر
خاموشیوں کا یہی انتقام تجھ سے رہے
اشارتاً ہی دعا و سلام تجھ سے رہے
بس ایک ربطِ مسلسل، مدام تجھ سے رہے
اسی طرح غمِ دل کو دوام تجھ سے رہے
دیارِ جاں میں سدا رنگِ شام تجھ سے رہے
دیارِ فن میں اگر میرا نام تجھ سے رہے

مغرب کا نظریہ ملکیت اور اسلام تقابلی جائزہ

Islam recognizes the right of individual ownership of material things in this world. A person can hold all kinds of Halal material things in his individual possession. However, Islamic Shari'a doesn't allow such a concept of individual ownership which is given in Capitalism and as adopted by Western world. The Western world's concept about individual ownership is very liberal and without any restrictions. While, Islam doesn't give full liberty to any individual but rather instructs them to own and possess Halal material things via legitimate sources, and also instructs the right usage of these material things in the light of Qur'an and Sunnah. The benefit of this Islamic law is that disqualified individuals, such as an insane person or children, have no right on disposing his or her individual property. Similarly, in the eyes of Islam, an individual person is not allowed to dispose his or her property in such a way which causes trouble and inconvenience to others, for example a person cannot dig a well on his own land which causes trouble and inconvenience to others. Islam prohibits such disposing of an individual's property.

Performance Analysis and Enhancement of Phased-Mimo Radar and Frequency Diverse Array Radar

Multiple-input-multiple-output (MIMO) radar and frequency diverse array (FDA) radar have gained significant attention from researchers community due to their numerous advantages over the phased-array radars. The distinguishing features of MIMO radar and FDA radar are waveform diversity and frequency diversity, respectively, while their phased-array counterpart lacks any such diversity. The hybridization form of MIMO and phased-array radars, called phased-MIMO radar, has also attracted the researchers attention due to its capability of combining the benefits of both. In this dissertation, phased-MIMO radar with closely spaced antennas and FDA radar with small inter-antenna frequency offset have been studied. To analyse the performance of radar, ambiguity function has proved to be a useful foundation. We have formulated ambiguity functions of phased- MIMO and FDA radars and derived their important mathematical properties. We have shown that FDA radar can promise better range resolution as compared to that of phased-array radar. For FDA we have proposed two novel schemes of inter-antenna frequency offset. Firstly, it is the time-dependent frequency offset as compared to the constant offset in the existing FDA. With the proposed idea a range-dependent beampattern can be synthesized with the maximum constantly illuminating the given target location. This is in contrast to the time-modulated beampattern with constant frequency offset. Secondly, we have proposed non-uniform (logarithmically increasing) frequency offset as compared to the uniform offset in the existing FDA. The proposed frequency offset promises a beampattern with a maximum only at the given target location. On the contrary, beampattern of FDA with uniform frequency offset exhibits multiple maxima in the visible range. The proposed schemes can provide a strong foundation for the development of modern radars capable of scanning the space more intelligently. We have investigated the proposed schemes only for linear array but they can be extended to planar arrays to scan the space in three dimensions.
