Trans-imperial mediations of the 'Turk': early modern depictions of Ottoman encounter in English drama and non-fiction prose
No full textMy dissertation will examine the role of the trans-imperial mediator in facilitating literary and cultural interactions between England and the Ottoman Empire in the early modern period. I define „trans-imperial mediator‟ to mean those travelers who shuttled between England and the Ottoman Empire, on behalf of their employers, for trade, intelligence-gathering, or diplomatic exchange. I argue that these mediators fashioned depictions of the Turk in response to their own trans-imperial anxieties. They imagined themselves to be aliens among the Ottoman subjects whom they encountered daily, despite sharing more in common with these Ottomans than the countrymen to whom they addressed their writing. At the same time, they felt equally uncertain about the prospects of returning home and being accepted as Englishmen, despite their assertions to the contrary. The identity that they created for themselves - Englishmen who were distinctly different from „the Turk‟ - must be understood as a response to their multiple identities and complex obligations. I argue that the „Turk‟ that these mediators introduced to English audiences must also be read as a composite creation – an imaginative response to the obligations of serving English interests while trying to live among the Ottomans. English playwrights recognized the creative opportunities allowed by dramatizing the polyvalent figure of the trans-imperial mediator to fashion their own types of Turks. Dramatists recognized the unique conjunctions between the vilified trans-imperial mediator and the Turk by using the play space to „recover‟ the imagined voice of the mediator and interrogate what anxieties occasioned the creation of particular types of Turk. English dramatists also introduced the figure of the trans-imperial mediator to a sympathetic audience – those discontented Englishmen who imagined escaping from the limiting social and economic conditions at home. Through lending the trans-imperial mediator a voice of his/her own, English „Turk‟ plays can be interpreted anew as interpretive paradigms for understanding how mediation functioned literarily in non-fiction accounts. Once we consider the shared investments that linked English trans-imperial mediators to their fictionalized counterparts, we may better understand why particular images of the 'Turk‟ must be interpreted through a web of domestic anxieties.Ph.D.Includes abstractVitaIncludes bibliographical referencesby Ameer Sohraward
Analysis of Photovoltaic Installations Performance and Deployment: Case Dubai Energy Sector
No full textThis thesis investigates the performance and degradation of photovoltaic (PV) systems in Dubai, a region characterized by its unique climatic conditions. With a growing emphasis on sustainable and clean energy, understanding the efficiency and longevity of PV installations in such environments is crucial. This study focuses on analyzing the Performance Ratio (PR) and degradation trends of two prevalent PV technologies: polycrystalline silicon (Poly-Si) and monocrystalline silicon (Mono-Si).
Employing a comprehensive dataset provided by Al-Suwaidi Constructions, the research analyzed PV systems across various strategic locations in Dubai, including Jebel Ali, Al Qusais, Al Barsha, and Al Lisaili. These systems, integrated directly with the grid and varying in capacity from 1.5 MW to 2 MW, were scrutinized over a five-year period (January 2018 to December 2022). The methodology involved a detailed PR analysis using linear regression models to identify long-term trends and annual degradation rates.
Key findings revealed that Poly-Si systems, despite being less efficient initially, exhibited lower annual degradation rates (-0.73% and -0.93%) compared to Mono-Si systems (-1.48% and -1.63%). This suggests a notable advantage in terms of stability and long-term performance for Poly-Si in harsh environments like Dubai. The study also contextualized these findings within the global landscape, comparing the performance of PV systems in various geographical settings.
The research contributes significantly to the field of renewable energy, providing valuable insights for stakeholders in selecting appropriate PV technologies considering environmental conditions and long-term efficiency. It underscores the importance of tailored solutions in the deployment of sustainable energy technologies, particularly in regions facing extreme climatic challenges
امیر خسرو، حسن سجزی اور واقعۂ اسیری: چند غلط فہمیوں کا ازالہ
No full textAmeer Khusrau, the great poet, prose writer, musician, Sufi, linguist and an intellectual, was arrested during a battle in Multan. Historians have given different accounts of Ameer Khusrau’s life and his arrest. One of such accounts is also attributed to Ameer Hasan Sajzi Dehlvi, a historian, writer and poet. The author of this article has proved that different narrations about Ameer Khusrau’s arrest have many inaccuracies and some of the writers have either misunderstood or misquoted the historians. The author feels that Ameer Khusrau, despite his genius, has not been treated fairly in the annals of history. He has proved with historical evidence in this article that many things and events quoted about Ameer Khusrau and his arrest are incorrect or only have half truths
Inequalities in photovoltaics modules reliability:From packaging to PV installation site
No full textIn recent years, the determination of the reliability of photovoltaic (PV) modules has been of ubiquitous interest to the PV industry. Therefore, this work reports on the reliability and degradation mechanism of 186 PV modules from packaging to installation stage. The paper shows that no cracks or hotspots affecting the PV modules before the packaging stage, while a minor reduction in the output power was observed at ±0.3%. The same PV modules were delivered using standard practice, and no further precautions were considered. Electroluminescent (EL) images of all PV modules were taken at the PV installation site, and it was discovered that 2.2% evolved cracks. Depending on the crack size, the estimated output power losses under standard test conditions varied from 0.53% to 1.43%. Furthermore, the PV modules were thermally inspected six months after being installed. It was found that hotspots developed in all the cracked PV modules, and their temperature increased from 10 °C to 20 °C. In addition, a potential induced degradation (PID) test was performed on the cracked PV modules and compared with a crack-free module. It was found that PID affected the modules with cracks more than the crack-free module

Am 26, 1060 (1956).Author Institution: Department of Physics, University of PittsburghMeasurements of the hydrogen iodide fundamental vibration-rotation spectrum at with a resolution of or better and a precision hydraulic wavelength have yielded values of line intensity of unusual accuracy. The line intensities have, in turn, been used as input data in the determination of individual line widths. Two meters of absorbing hydrogen iodide were pressurized to one atmosphere with nitrogen as a non-absorbing broadening additive with the result that the line widths were comparable with the slit width. Thereupon, point by point conversion of the transmission curves to plots of the absorption coefficient permitted direct determination of the line intensity . Finally, small corrections for instrumental smearing were introduced in the manner of the Kostkowski and treatment as well as wing corrections to replace the portions of the Lorentz curve which could not be differentiated practically from the noise. Present unsmoothed results are as follows: [FIGURE] These indicate a value for the integrated band intensity of only at Thus, the coefficient of the linear term in the electric dipole moment expansion is very small and the effect of vibration-rotation interaction may be expected to be quite marked. As the table shows, the R-branch is in fact considerably enhanced at the expense of the P-branch. The value of the interaction parameter computed from relative intensities near the center of the band is
