پیر عبدالقادر

پیر عبدالقادر ؒ
)دین پور شریف والے(
پیر اساڈے عبدالقادر جیہڑے دین پور والے
دین نبیؐ دی خاطر جنھاں لکھاں دکھڑے جالے
شاہ عبدالرحیم تے عبدالقادر نے سب کرم کمایا
خواجہ اللہ بخش نے یارو فیض انہاں توں پایا
جٹو والے ٹبے اُتے تنبو دین دا لایا
دین دے اس چشمے توں لوکی بھر بھر پین پیالے
خواجہ اللہ بخش بہاولنگر چ قدم ٹکایا
دین دی روشنائی نوں ایتھے آپ نے سی پھیلایا
جٹو والہ بنیا مرکز، دین پور نام رکھایا
جگ وچ دھماں پیاں ہر کوئی دین پور نوں بھالے
حضرت دے رہے بیٹے دونویں درس قرآن پڑھاندے
شرع و حدیث تے فقہ فقر دے دیوے رہے جلاندے
لنگر پانی ہر اک نوں اوہ گھروں رہے کھواندے
شہر محلے کوچے گلیاں چرچے ہون دوبالے

حضرت یحییٰ پوتے سن جو ، بہتی شہرت پائی
جس تے نظر کرم دی کردے دل دی کرن صفائی
ذکر اذکار تے عشق نبی ؐ وچ فقر دی جوت جگائی
ایویں فیض روحانی ملدا جوں مینھ وچ ویہن پرنالے
شکل شبہات سی آپ دی ایسی من چ اتردی جاوے
ویکھے جیہڑا ول ول ویکھے فر وی صبر نہ آوے
چولا آس، رومال دا گھونگھٹ ، حضرت نوں بھاوے
دلوں بجانوں منیا جہناں بن گئے دین دے رکھوالے
حضرت جی دے بیٹے سارے پیار بھرے نے بھائی
ایہناں وچوں پیر عبدالقادر بہتی شہرت پائی
کرے دعا تے ہووے شفاء رب سوہنے گل بنائی
جہڑے در تے آون رب دکھ انہاندے ٹالے
قادری سائیںؔ در انہاں دے بہہ کے فیض کمائیے
جئے کر صدق یقین تھیں بہئے کدی وی تھوڑ نہ پائیے
رب کرے در اوہناں دے اسیں سارے آئیے جائیے
جہیڑا اوہناں دے...

Density of Aedes Aegypti Larvae Based on Knowledge, Attitude, and Action to Eradicate Mosquito Nest in Daya Market of Makassar City

Dengue Hemorrhagic Fever (DHF) is a disease caused by a dengue virus infection which is transmitted through the bite of the Aedes aegypti mosquito. To prevent the occurrence of dengue cases, it is necessary to eradicate mosquito nests. The market is one of the public places that has a risk of dengue transmission. This study aims to determine the density description of Aedes aegypti larvae based on the knowledge, attitudes and actions of cleaning managers, traders and visitors to Pasar Daya Makassar City. This type of research is descriptive observational. The research samples were cleaning managers, traders and visitors as well as containers at Pasar Daya and at the respondent's house. Sampling for respondents using purposive sampling method using inclusion and exclusion criteria. The results showed that the number of containers positive for ae. Aegypti larvae in the Daya market was 34 containers with a container index value (CI) = 35.4% and the value of Density Figure (DF) 8 and the presence of Ae. Aegypti larvae in the respondent's house (positive) amounting to (51.4%). At the level of knowledge of respondents in the poor category (68.6%), while the attitudes and actions of respondents in the poor category showed a high enough percentage, namely 65.7%, and (68.6%). Based on the results of this study, it can be concluded that the density of Aedes aegypti larvae in Pasar Daya Makassar City is in the high category.

Higher Order Sliding Mode Control Based Sr Motor Control System Design

This thesis presents a novel scheme for speed regulation/tracking of Switched Reluctance (SR) motors based on Higher-Order Sliding-Mode technique. In particular, a Second-Order Sliding-Mode Controller (SOSMC) based on Super Twisting algorithm is developed. Owing to the peculiar structural properties of SRM, torque produced by each motor phase is a function of phase current as well as rotor position. More importantly, unlike many other motors the polarity of the phase torque in SR motors is solely determined by the rotor position and is independent of the polarity of the applied voltage or phase current. SR motor needs an electronic commutation scheme for its operation. So design of commutation scheme plays an important role in motor efficiency and performance. This commutation scheme is embedded in its power supply as switching timers. The existing commutation schemes cause high power loss and based on those commutation schemes, the existing controller techniques for SR motor show low robustness especially when motor’s parameters change. Therefore a new commutation scheme is developed which optimizes power consumption in motor phases. On the bases of this commutation scheme, a new controller technique is used to design controller for SR motor which is highly efficient, simple to design and easy to implement and also provides sufficient robustness against parameter variations and unknown disturbances. The proposed controllers take advantage of this property and incorporate a commutation scheme which, at any time instant, selects to energize only those motor phases for the computation of control law, which can contribute torque of the desired polarity at that instant. This feature helps in achieving the desired speed regulation/tracking objective in a power efficient manner as control efforts are applied through selective phases and phases producing the torque of opposite polarity are kept switched off. This approach also minimizes the power loss in the motor windings reducing the heat generation within the motor. The common techniques for designing the SR Motor controls are fuzzy logic control, Artificial Neural Network (ANN) and feedback linearization. Fuzzy logic control provides sufficient robustness against parameter variations but at a high computational cost. Artificial Neural Network (ANN) shows good dynamic response against unknown disturbances but problem in using this technique is requirement of a large training data set. In the feedback linearization technique, nonlinear control problem is transformed into linear control problem and then any one of the well established and mature linear controller techniques are applied on the resulting system. Feedback linearization cannot be applied to all types of nonlinear systems; and in case of parameters uncertainties, the robustness cannot be guaranteed. All the deficiencies in discussed techniques can be overcome by introducing sliding mode control which is simple, easy to implement and provides robustness. The inherent problem of chattering in classical FOSMC can further be improved by using higher order sliding mode control (HOSMC). In order to highlight the advantages of Higher-Order Sliding-Mode controller, a classical First-Order Sliding-Mode controller (FOSMC) is also developed and applied to the same system. The comparison of the two schemes shows much reduced chattering and low power consumption in case of SOSMC. This feature is especially very important for SR motor control, due to reduced chattering; wear and tear problem of actuators is reduced. The responses of synthesized controllers are also investigated against changes in moment of inertia which could be due to engagement of load; stator phase resistance which could vary due to temperature variations in winding during operation and coefficient of viscous friction as a model uncertainty. The performance of the proposed SOSMC controller for speed regulation is also compared with that of another sliding mode speed controller published in the literature and also with dynamic sliding mode controller. The same technique is also applied on position control problem and, FOSMC and SOSMC are developed for position regulation problem; making it possible candidate for servo drive application.
