غزلیات
زندہ رکھی ہے ترے پیار کی خوشبو ایسے
اپنے شعروں میں دیے تیرے حوالے میں نے
کیوں نہ ہر لفظ پہ آنکھوں سے یہ ٹپکیں آنسو
جس قدر درد ملے شعر میں ڈھالے میں نے
ز
اپنی ذات کے اندر آ!
خواب نگر سے باہر آ!
شیش محل میں کس نے کہا
ہاتھ میں لے کر پتھر آ!
دیکھ کے صحرا نے یہ کہا
آنکھ میں بھر کے ساگر آ!
تجھ سے مسخر دل نہ ہو گا
لاکھ تو بن کے سکندر آ!
ہنس کے کہا درویش نے یہ
غم کی آگ میں جل کر آ!
ز
یوں تو کہنے کو فقط صبح کا تارا ڈوبا
ہاں، مگر رات کے راہی کا سہارا ڈوبا
جس کی باتوں سے سدا پیار کی کرنیں پھوٹیں
اُس کی آنکھوں میں مری سوچ کا دھارا ڈوبا
میری قسمت بھی ہے روٹھی مرے ساجن کی طرح
میں جو منجدھار سے نکلا تو کنارا ڈوبا
آج پھر سُرخ گھٹائوں کی ہے آمد آمد
آج پھر ۱ور کوئی درد کا مارا ڈوبا
کیسا کہرام مچا ہے لبِ دریا یونسؔ
ایسا لگتا ہے کوئی جان سے پیارا ڈوبا
ز
مل کر جو چلا جاتا
کیا اس میں ترا جاتا
معیار سے اپنے تو
کیوں کر ہے گرا جاتا
منزل نہ بھلے ملتی
رستہ تو دیا جاتا
ہوتی ہے وہاں غیبت
میں کیسے بھلا جاتا
ز
اب خونِ جگر دے کے یہ پالا نہیں جاتا
آ جا کہ ترا درد، سنبھالا نہیں جاتا
ہم جس کے سبب نقل مکانی پہ تلے ہیں
کیوں شخص وہ بستی سے نکالا نہیں جاتا
روتے ہو یہ بتلائو کہ تم ہجر میں کس کے
بے وجہ تو آنکھوں کا اُجالا نہیں جاتا
Fine Arts, shows the aesthetic side of any society and it is very important part of any culture, as its presence expresses the cultural diversity and richness and connects different segments of society. This article throws a light on the fine arts of Makkah society before the Prophet Hood. It is very common among historians and orientalists to accuse the society of Makkah void of any cultural expression apart from its love for poetry, which is not true. The matter of the fact is that this society was fully developed aesthetically despite its nomadic and barren desert life. The cultural expressions of storytelling, poetry, architecture, painting, sculpture making were true and pure to this part of world without any influence from outside world. The tradition of storytelling was an essential element of Makkah cultural life and it was common among the elite of Makkah to have night sittings, where along with drinking, music they used to narrate anecdotes of past. Although the architecture of Makkah people was simple, it was self-sufficient to the needs of the environment. This research paper is an attempt to look into the various forms of Fine Arts of Makkah and how these expressions were deeply embedded in the society.
Modern technological systems consist of many components with strong interactions between them. Faults may cause an unacceptable loss of the system functionality, instability, or fatality. Systems capable of automatically detecting, diagnosing faults, and maintaining the overall functionality are desirable. Fault diagnosis (FDD) is a process that detects, locates, andnds nature of fault. Fault tolerant control (FTC) system has the ability to tolerate faults. Among dynamical systems, switched systems (SS) have numerous applications in control of robotics, automotive industry, aircraft and air tra c control, industrial electronics (power converters) etc. A typical SS is composed of a family of subsystems and a rule that governs the switching among them. Ideally, the FDD/FTC systems are designed on the basis of assumption that it is switching synchronously with corresponding subsystems of SS; that is; FDD/FTC system switches exactly at the time of switching in the switched system to be monitored. However, in practice, the switching in FDD/FTC system lags the switching of the switched system to be monitored. This creates a particular interest in the design of FDD/FTC systems especially when there is event-based switching. In this dissertation, the term\asynchronous" is used to illustrate this situation. This thesis studies the design of FDD and FTC systems of SS under asynchronous switching scenario, in the presence of disturbances and noise (unknown inputs). In therst part, a framework for fault detection and isolation (FDI) is proposed. The residual (symptom signal) is so generated that it is sensitive to faults and robust against disturbances. A multi-objective problem is formulated based on H?=H1ltering. Using the average dwell time approach and the piecewise Lyapunov function technique, su cient conditions are suggested in terms of linear matrix inequalities (LMIs) to guarantee the stability and desired performance. In addition, the proposed framework has also been extended to design FDI strategy for uncertain SSs. A norm-bounded uncertainty is considered. To improve the FDD capability adaptive threshold scheme is developed. xiii In the second part, fault estimation (FE) and FTC schemes are proposed. The proposed framework is based on unknown input observer (UIO) and H1 optimization. On the basis of FE, recon guring control law approach is utilized to tolerate faults. To this end, an integrated approach for FE/FTC is proposed for SSs. The last part of this dissertation addresses another very important problem of highly practical interest; that is, the design of fault detection (FD) scheme for switched system with state delays, under asynchronous switching. The tools from robust control theory, Lyapunov stability theory, and linear matrix inequality are used to propose the schemes. To demonstrate the e ectiveness of the proposed schemes, the algorithms have been tested on the dynamics of highly maneuverable aircraft technology (HiMAT) and battery converter unit (BCU) of hybrid electric vehicle.
