Search engine for books / Amierul Izzuddin Azman
No full textSearch engine is web-based software that searches for and identifies things in a collection that match the user's keywords or characters, and is mostly used to locate specific websites on the Internet. The basic idea of information retrieval (IR), as is well-known in the computer industry, is to search a given amount of data and retrieve those records that fulfil a set of criteria. For this project, it will be more on developing a search system that focus on the domain of books. Although many search engines available for book searching, most of them still have room for improvement. The reality to find books using search engine are quite challenging because, the users need to know the title of the book in order to retrieved relevant result from the search engine. Therefore, this project aims to propose a search engine that might produce better result by manipulating the indexing structure of the search engine. Software Development Life Cycle also known as SDLC was used as the methodology in this project development. This project applies the vector space model for the matching process, because the chosen software library for this project which is Apache Lucene is using the vector space model as its foundation. In addition, the Bag-of-Words approach was used as the basis for the indexing module. The indexing process indexed the information of the books such as the book title, the author name, publisher, year published, pages count and synopsis of the book. The search engine's assessment criteria include recall and precision. In IR, recall and precision have long been used as standard evaluation criteria. Keenly, the results of this project prove that index files that contain more domain information can increase the relevancy of a search engin

P. O. Box 22452
Riyadh 11495, Saudi ArabiaThe K0-group for unital C*p –algebra is defined. Then it is proven that the K0 -group of unital commutative C∗p-algebra (A, ||.|| p ) is
isomorphic to the K0-group of the commutative unital C*p –algebra ( (A, ||.|| p)1 p ). The concept of n-special C*p –algebra was introduced by Azmi in [2]. Let A be an n-special C*p –algebra then the characterization of these algebras as in [2] leads to a surjective group homomorphism from K0(A) to Z, which turns into isomorphism when A is a special C*p –algebr
Conducting political research in a highly sensitive post-conflict environment: Reflections from the internally displaced camps in Kenya / Muhammad Danial Azman
No full textThis article elucidates the ethical and methodological intricacies of the semi-structured interviews when the author conducted is qualitative-based fieldwork in the Internally Displaced Camps (IDPs) in Nairobi and Rift Valley, Kenya. Research can be regarded as the production of knowledge, and the research process is the roadmap used in order to produce scientific knowledge about the objectivity of individual agency and its social reality, but there is a paucity of recent studies that reveal the complexity of conducting research in highly sensitive environments, especially in the IDP camps. This study hopes to fill in the gap in scholarship by interviewing the survivors of the post-election violence (PEV) who occupied the IDP camps and urban slums using a framework of research ethics on the IDPs. The essay looks into the process of ethical and moral considerations in response to the issues of political sensitivity when interviewing the IDPs. The paper begins with a brief introduction to the case study. Secondly, the research ethical framework and the actual research design are discussed. Following this, the challenges faced by the author regarding research important decisions made before, during and after the fieldwork (research steps and processes) are examined. The analysis concludes by suggesting the research prospects and limitations of the semi-structured interview method in the IDP camps and highlights the importance of recognising the 'positionality' of the researcher from just 'observing' to the furthe

Implementasi Kaidahla Yunkiru Tagayyur Al-ahkam Bitagayyur Al-azman Wa Al-ahwal Dalam Ibadah Di Masa Pandemi
No full textCovid 19, which spread on the earth, changed the whole social order, be it economics, education, politics, health and even the way of Muslims, especially worship. This is caused by an emergency requiring everyone not to carry out activities outside the home, so that the impact on all worship activities that should be carried out by worshiping in the mosque must be avoided. In this article the author tries to explore changes in law if viewed from the side of the rule “La Yunkiru Tag{ayyur Al-Ahkam Bitag{ayyur Al-Azman wa Al-Ahwal” (not denied the change in a law due to the eruption of the times and circumstances) during a pandemic. This principle becomes the basis of the flexibility of Islamic law in accordance with the development and conditions of the times. So that Islamic law is always present as a law in accordance with human history throughout the ages from the time of Adam to the end of time. Islam is always suitable and in accordance with all climates and all nations throughout the world. It is a religion that remains perfect when faced with all the changes that are continually there. Islam comes with ease and flexibility, not a religion that has not been stagnant when responding to changing timesKey words: Covid 19, Islamic Law, Changing Times Covid 19 yang merebak di bumi merubah tatanan bermasyarakat seluruhnya, baik ekonomi, pendidikan, politik, kesehatan bahkan cara umat Islam beragama khususnya ibadah. Ini oleh akibatkan olehkondisi darurat menuntut setiap orang untuk tidak melakukan aktivitas di luar rumah, sehingga berdampak pada seluruh aktivitas ibadah yang harusnya dilaksanakan dengan caraberjamaah di masjid harus dihindari.Dalam artikel ini penulis mencoba menggali Perubahan hukum jika ditinjau dari sisi kaidah “La Yunkiru Tagayyur Al-Ahkam Bitagayyur Al-Azman wa Al-Ahwal”(tidak diingkari berubahnya sebuah hukum disebabkan karena berubanhya zaman dan keadaan) di masa pandemi.Kaidah ini menjadi dasar fleksibelitas syariat Islam yang sesuai dengan perkembangan dan keadaan zaman.Sehingga syariat Islam selalu hadir sebagai syariat yang sesuai dengan sejarah manusia sepanjangzaman sejak masaNabi Adam hingga manusia akhir zaman.Islam selalu cocok dan sesuai dengan segala iklim dan segala bangsa di seluruh dunia.Ia agama yang tetap sempurna ketika dihadapkan pada segala Perubahan yang terus menerus ada. Islam datang dengan kemudahan dan keluwesan bukan agama yang jumud (stagnan) tidak bisa berkembang saat merespon Perubahan keadaan zaman
Effects of weaving patterns towards different welded joints
No full textWelding plays major role in shipbuilding activities as it joins most metals. This requires many welders to be employed. When it comes to weaving, most welders have preferable patterns. There will be circular in motion, zigzag, crescent, straight and many more. Weaving can be defined as the way of manipulation of the torch during the welding process. However, there was no analysis done to study their effects on heat affected zone (HAZ) for each type of welded joint. In this paper, the author will focus on tee and butt joint
Nonexistence of global solutions for fractional temporal Schrödinger equations and systems
No full textWe, first, consider the nonlinear Schrödinger equation
