Smart Scheduling of EVs Through Intelligent Home Energy Management Using Deep Reinforcement Learning
No full textThis article presents the deep reinforcement learning (DRL) based smart scheduling in intelligent home energy management system (SSIHEMS) for electric vehicles (EVs) scheduling by utilizing the photovoltaic (PV) on the rooftop for economic dispatch problems. Therefore, optimizing home appliances to minimize consumption cost is challenging because of the randomness of electricity prices and poses a challenge for efficient scheduling. The data-driven model-free DRL-based SSIHEMS is utilized to optimize the decision by managing different home appliances and offering appropriate scheduling EVs to overcome the shortcomings. The decision includes the proper scheduling of battery charging, discharging, and EV to reduce the dependency on the electric grid through a collaborative approach. In addition, the proposed work covers designing a gym-based environment that incorporates the states fed to an agent and receives the reward based on the action taken for scheduling. Hence, the case study is performed to validate the proposed approach. It is verified that the decisions for battery charging, discharging, and EV scheduling are managed well through PV generation with respect to time. Furthermore, to verify the robustness and effectiveness, a comparison of different algorithms such as deep Q-network (DQN), double DQN, and dueling DQN
Introducing Iqbal the Economist
Get PDFThe Iqbal Memorial Lecture was instituted in 1994 when the Pakistan Society of Development Economists (PSDE) celebrated the completion of a decade of steady progress. A brief announcement stated: “The Iqbal Memorial Lecture attributed to the national poet [Emphasis added], Allama Muhammad Iqbal has been included in the programme for the first time. Professor Ian M. D. Little is delivering that lecture” [Secretary’s Report (1994), p. 1472]. Iqbal, the poet and philosopher par excellence, has made incisive remarks or comments on economic and social issues in his poetry, philosophical writings, and in the course of his discourses as well as some famous letters, particularly those written to the Quaid-i-Azam, Muhammad Ali Jinnah, the founder of Pakistan. But these do not make Iqbal an economist. The Secretary of the PSDE was, therefore, careful in observing that the lecture commemorates our “national poet”. However, it will be of great interest to this largest national congregation of economists and other scholars concerned with development to know that the very first published book of Iqbal related neither to poetry nor philosophy, but economics. It was written in Urdu. He also taught the subject at undergraduate and Master’s level, even though he had not studied it as a student. At the Government College, Lahore, Iqbal studied English, Philosophy and Arabic for his B.A. and then completed the M.A. in Philosophy.

ABSTRACT:
Muhammad Wasil and K.H. Ahmad Ghozali has a history of studying astronomy with Kiai Noor Ahmad Jepara (deceased), author of the book of astronomy Nur al-Anwar. Even so, Muhammad Wasil and K.H. Ahmad Ghozali has a different method for predicting the phenomenon of a solar eclipse. These two calculation methods are often used as references in predicting solar eclipse phenomena, even though they have different final results. This research is intended to answer the questions: (1) What is the method for calculating global solar eclipses by Muhammad Wasil and K.H. Ahmad Ghozali? (2) What is the comparison of the level of accuracy of the global solar eclipse calculation method of Muhammad Wasil and K.H. Ahmad Ghozali? (3) What are the advantages and disadvantages of the global solar eclipse calculation method Muhammad Wasil and K.H. Ahmad Ghozali? Problems are discussed through literature study by collecting data through documentation and interviews. All data is analyzed and compared with NASA results as a reference for accuracy levels.
This research concludes: Firstly, the calculation methods of Muhammad Wasil and K.H Ahmad Ghozali have similarities using the concept of a geocentric ecliptic coordinate system, apart from that there are differences between the two calculation methods including the concept of the shape of the Earth used, data sources, provisions for delta T(∆T), and the approach used in the calculation method. Second, the level of accuracy of the global solar eclipse calculation method K.H. Ahmad Ghozali's calculation method is higher than Muhammad Wasil's in predicting the phenomenon of a solar eclipse. This level of accuracy is based on calculating the state of the greatest eclipse which has a direct impact on the implementation of eclipse prayers. Third, Muhammad Wasil's method for calculating global solar eclipses has the advantage of contacts being calculated more completely, being able to depict a map of the movement of the eclipse, a higher level of accuracy in calculating umbral contacts, while there are disadvantages, namely that it is difficult to implement without the help of a program as a tool. In the calculation method for global solar eclipses, K.H. Ahmad Ghoazali has advantages, including a more practical calculation method, having a high level of accuracy for penumbral contact and the peak of the eclipse (greatest eclipse), while his disadvantages are low accuracy in calculating umbral contact for global solar eclipses.
Keywords: Muhammad Wasil, K.H. Ahmad Ghozali, global solar eclipse

Perihal gurindam [About stanza]
No full textArtikel ini berkenaan dengan perihal 'gurindam'. Menurut R.J. Wilkinson, kekata gurindam berasal daripada bahasa Sanskrit dan bermakna rangkap yang menjadi bidalan atau pepatah berangkap yang berpadan dengan tempatnya, sesuai rangkap dengan maksudnya; sesuai pemula dengan kesudahannya; sesuai sebab dengan akibatnya dan seimbang salah dengan hukumnya. Za'ba menjelaskan bahawa gurindam itu suatu jenis syair yang berjela, rangkapnya bersukat tetapi tidak tetap. lsi gurindam ialah fikiran yang bernas, yang disampaikan dengan bahasa nyanyian yang kemas dan riang. Gurindam membawa bahasa tamsil, ibarat dan umpama, serta melukiskan isinya dengan warna yang indah lagi bijaksana. Za'ba menyatakan seterusnya: isi gurindam dinyatakan terus-menerus sahaja. Dengan bahasa yang riang (humour), banyak gurindam tua yang lekat pada lidah Melayu sebagai bidalan. Contoh dua buah gurindam yang disiarkan media cetak ialah Gurindam Melayu, karya Zafilin A Hamid dan salinan kedua daripada 12 rangkaian Gurindam Duabelas, ciptaan Raja Ali Haji bin Haji Ahmad pada tahun 1846. Selain menyatakan sebab-akibat, Gurindam Duabelas membawakan iktibar dan nasihat yang disampaikan menerusi lukisan, kiasan dan ibarat. Penulis memberikan penjelasan mengenai jenis-jenis gurindam seperti gurindam bersajak, yang tidak bersajak, tidak bersukat dan gurindam melarat. This article is about 'gurindam'. According to R.J. Wilkinson, the word 'gurindam' was originally from the Sanskrit language and means stanzas of discourse that are a kind of proverb, which is suitable with the situation and time; with a beginning and ending; its cause and effect; and balanced with the law and its consequences. Za'ba explained that 'gurindam' is a lengthy poem, measured but not fixed stanzas. The 'gurindam' contents are thoughtful, delivered with a neat and concise language, fresh, and allegorical. 'Gurindam' carries the language full of examples, parables and metaphors; and depicts its contents with colour and wisdom. Za'ba further states that the contents of 'gurindam' are expressed continuously. The author found two 'gurindams' on the printed media; one is the Gurindam Melayu, by Zafilin A Hamid. The other was the second of the 12 series of Gurindam Duabelas, created by Raja Ali Haji bin Haji Ahmad in 1846. The 'gurindam duabelas' brought teachings and lessons expressed by words painting a picture, figuratively and allegorically. The writer gives further explanations on the types of 'gurindam' such as the 'gurindam bersajak' (rhyme), 'tidak bersajak' (does not rhyme), 'tidak bersukat' (unmeasured) and 'gurindam melarat' (lengthy gurindam)
