Superiority of the r-k Class Estimator Over Some Estimators In A Linear Model
No full textWOS: 000305514300014In regression analysis, to overcome the problem of multicollinearity, the r - k class estimator is proposed as an alternative to the ordinary least squares estimator which is a general estimator including the ordinary ridge regression estimator, the principal components regression estimator and the ordinary least squares estimator. In this article, we derive the necessary and sufficient conditions for the superiority of the r - k class estimator over each of these estimators under the Mahalanobis loss function by the average loss criterion. Then, we compare these estimators with each other using the same criterion. Also, we suggest to test to verify if these conditions are indeed satisfied. Finally, a numerical example and a Monte Carlo simulation are done to illustrate the theoretical results.Cukurova University Academic Research ProjectsCukurova University [FEF-2008D17]; TUBITAK-BIDEBTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK)This research was supported by Cukurova University Academic Research Projects under project number FEF-2008D17.

Mullah Sadullah al-Fatlawi and His Work of et-Tibyân fî Tasrîfi Kalimâti'l-Qurân
No full textBu çalışma, hala hayatta olan ve Diyarbakır'da ikamet eden Molla Sadullah'ın hayatı ve 'et-Tibyân fî Tasrîfi Kelimâti'l-Kur'ân adlı eserini ele almaktadır. Molla Sadullah, bu eserinde Kur'ân'ı Kerîm'de geçen bazı kelimelerin aslını, sarf açısından geçirdikleri değişiklikleri, kelimelerin anlamlarını, kıraat farklılıklarını izah etmektedir. Söz konusu eseri, Kur'ân'da geçen bazı kavramların köklerini ve bu köklerin uğradığı i'lâl, idgâm ve kalb gibi sarfla ilgili kuralların izahı ve buna bağlı olarak da onlarda meydana gelen değişikliklerin ortaya konulması açısından çok önemli bir çalışmadır. Kur'ân'da geçen ve mevzu bahsi olan kelimelerin uğradığı değişimleri sarf ilmi açısından izah etmekle kalmayan müellif, söz konusu kelimelerin geldikleri farklı manaları da bazen ayrıntılı bir şekilde ele alarak ilim talebeleri ve onları yetiştiren hocaların istifadesine sunmaktadır.This study examines the work of Mullah Sadullah, who is still alive and residing in Diyarbakır, called 'et-Tibyân fî Tasrîfi Kelimâti'l-Qur'an'. This book explains the originals of some of the words in the Qur'an surahs, the stages they went through in terms of consumption, the meanings of the words, and the differences in recitation. It is a very important study for students in terms of explaining the roots of the concepts of the Qur'an and how these roots change with i'lâl and iqlâb. Not only does the author show the change that the words of the Qur'an have undergone, but also explains the different meanings of the words, sometimes in detail, and presents them to the benefit of the students of science and the teachers who train the students

Yaşadığımız dönemde bu kadim şehirde yetişen değerli âlim ve şahsiyetlerden biri, Molla Sadullah el-Fetlevî'dir. Nahiv, sarf, lügat, fıkıh, tefsir ve hadis gibi ilim dallarında ihtisas sahibi olan el-Fetlevî, nahiv ve sarf başta olmak üzere pek çok ilim dalında eser telif etmiş ve çok sayıda makale yazmıştır. Onun en önemli eserlerinden biri, Abdülgafûr el-Lârî'nin (ö. 912/1506) Hâşiye 'alâ şerhi'l-Câmî li'l Kâfiye adlı eseri üzerine kaleme almış olduğu'Avnu'l-Bârî fî Halli Ba'di Müşkilâti'l-Lârî adlı kitabıdır. Çalışmamızın konusu olan 'Avnu'l-Bârî fî Halli Ba'di Müşkilâti'l-Lârî adlı eser, 98 varaktan oluşmaktadır. Eserin mukaddimesinde pek çok edebi sanata yer veren yazar, garip ifadeler kullanmış ise de metin kısmını anlaşılır ve yalın bir dille yazmıştır. Müellif, söz konusu eserde Abdülgafûr'un ismin özelliklerinden izafet konusuna kadar olan kısmı ele alıp şerh etmiştir. Bu tez çalışmasında Molla Sadullah el-Fetlevî'nin hayatı ve ilmi şahsiyeti ile İbnü'l-Hâcib, Molla Câmî ve Abdülgafûr el-Lârî'nin hayatı ele alınmıştır. Haşiyetu 'Abdilgafûr 'ala şerhi'l-Câmî ve el-Fetlevî'nin'Avnu'l-Bârî fî Halli Ba'di Müşkilâti'l-Lârî'nin genel özellikleri hakkında bilgiler verilmiştir. Bunun ardından el-Fetlevî'nin 'Avnu'l-Bârî fî Halli Ba'di Müşkilâti'l-Lârî adlı eserin tahlil ve tahkiki yapılmıştır.Diyarbakır, which is one of the most important cities of the region and contains ancient cultures and civilizations, has been an important scientific center that has been the cradle of science and wisdom for a long time. As in the past, great scholars have been trained in the scientific institutions located in its basin. One of the valuable scholars and personalities who grew up in this ancient city during the period we live in is Molla Sadullah al-Fetlawi. Al-Fetlawi, who is a scholar and scholar in branches of science such as nahiv, lexicography, fiqh, tafsir and hadith, has written works in many branches of science, especially nahw and sarcasm, and has written many articles. One of his most important works, Abdulgafur al-Lari 'Avnu'l-Bârî fî Halli Ba'di Müşkilati'l-Lârî, which was written on the work of Hâşiyetu 'Abdilgafûr 'ala'l-Câmî. The work called 'Avnu'l-Bârî fî Halli Ba'di Müşkilati'l-Lârî', which is the subject of our study, consists of 98 pages. The author, who included many literary arts in the introduction of the work, used strange expressions, but wrote the annotation part in an understandable and plain language. In the work in question, the author has discussed and annotated the part of Abdulgafur's name from the characteristics of the name to the subject of relativity. In this thesis, the life and scientific personality of Molla Sadullah al-Fetlawi and the life of Abdulgafur al-Lari are discussed. Information has been given about the general characteristics of Hashiyetu 'Abdilgafûr 'ala'l-Câmî and al-Fetlevî's 'Avnu'l-Bârî fî Halli Ba'di Müşkilati'l-Lârî. After that, the analysis and verification of al-Fetlevî's work called 'Avnu'l-Bârî fî Halli Ba'di Müşkilati'l-Lârî was made

Get PDFCarbon Monoxide and Sulfur Dioxides concentrations and traffic volume data were
collected at several locations in Ipoh City in the state of Perak in Malaysia. The sites were
categorised into an enclosed area and an open area and at each site different vehicles driving
mode were considered. A mathematical models based for pollutant concentration were
developed using the least square method. Results from these studies indicate that the
maximum concentration of pollutant is higher in an enclosed surrounding for all driving
modes compared to an open surrounding similar traffic volume. The relationships derived
between traffics flows and pollutants concentrations indicate that the adopted approach to
forecast pollutant levels from traffic counts is workable for Malaysian situation. (Abstract by author
Innovative Fluorescent Polymers in Niosomal Carriers: A Novel Approach to Enhancing Cancer Therapy and Imaging
No full textCancer is anticipated to become the pioneer reason of disease-related deaths worldwide in the next two decades, underscoring the urgent need for personalized and adaptive treatment strategies. These strategies are crucial due to the high variability in drug efficacy and the tendency of cancer cells to develop resistance. This study investigates the potential of theranostic nanotechnology using three innovative fluorescent polymers (FP-1, FP-2, and FP-3) encapsulated in niosomal carriers, combining therapy (chemotherapy and radiotherapy) with fluorescence imaging. These cargoes are assessed for their cytotoxic effects across three cancer cell lines (A549, MCF-7, and HOb), with further analysis to determine their capacity to augment the effects of radiotherapy using a Linear Accelerator (LINAC) at specific doses. Fluorescence microscopy is utilized to verify their uptake and localization in cancerous versus healthy cell lines. The results confirmed that these niosomal cargoes not only improved the antiproliferative effects of radiotherapy but also demonstrate the practical application of fluorescent polymers in in vitro imaging. This dual function underscores the importance of dose optimization to maximize therapeutic benefits while minimizing adverse effects, thereby enhancing the overall efficacy of cancer treatments. This study evaluates the use of three fluorescent polymers (FP-1, FP-2, FP-3) encapsulated in niosomes for combined cancer therapy and imaging. Tested across cancer cell lines, these formulations enhance the effects of radiotherapy and allow for in vitro imaging of cancer cells. The findings emphasize the significance of dose optimization in improving treatment.
