No full textPosition of Ministers in Manshaat Salatin moenodin parvaneh-shamsodin esfahani-salahodin ayboubiManshaat Salatin is a work by an unknown author in the sixth and seventh centuries, written on the subject of the principles of governmental and bureaucratic correspondence (including: greetings, condolences, rites, ranks, government orders, spelling rules, exaggeration methods, etc.). Using a descriptive-analytical method, this article examines the letters of three ministers (Shams-ud-Din Isfahani, Moin-ud-Din Parvaneh and Salah-ud-Din Ayoubi) and explores the social, historical and cultural characteristics of that era. There has been no methodical or academic research on Manshaat Salatin.The results of the research show that Iranshahri ideas have been prominently highlighted in Manshaat Salatin. Through the letters, the authors have called on their audiences to be truthful, just, and reasonable, and in fact have developed an independent and documented code of conduct that has prevented the premature deviation and decline of the government.Keywords: Manshaat Salatin, Content-Based Stylistics, Court correspondence, Iranshahri Idea
Constant market shares analysis: uses, limitations and prospects
Get PDFIn this paper, we generalise the constant market shares (CMS) framework, with particular attention to the underlying theoretical conditions required for diagnostic interpretation. The approach is applied to the analysis of the export performance of the Australian processed food sector in South-East Asia over the period 1980–2003. We conclude that the usefulness of CMS analysis for evaluating a country’s international trade performance depends upon the empirical validity of the aggregation assumptions implicit in the diagnostic interpretation.aggregation, Armington model, competitiveness, constant market shares, Marketing,
Long-term Behavior of Mean-field Noisy Bounded Confidence Models with Distributed Radicals
Get PDFIn this article, we study the nonlinear Fokker-Planck (FP) equation that arises as a mean-field (macroscopic) approximation of bounded confidence opinion dynamics, where opinions are influenced by environmental noises and opinions of radicals (stubborn individuals). The distribution of radical opinions serves as an infinite-dimensional exogenous input to the FP equation, visibly influencing the steady opinion profile. We establish mathematical properties of the FP equation. In particular, we, first, show the well-posedness of the dynamic equation, second, provide existence result accompanied by a quantitative global estimate for the corresponding stationary solution, and, third, establish an explicit lower bound on the noise level that guarantees exponential convergence of the dynamics to stationary state. Combining the results in second and third readily yields the input-output stability of the system for sufficiently large noises. Next, using Fourier analysis, the structure of opinion clusters under the uniform initial distribution is examined. The results of analysis are validated through several numerical simulations of the continuum-agent model (partial differential equation) and the corresponding discrete-agent model (interacting stochastic differential equations) for a particular distribution of radicals

Amordaad, Songs of Persia II
Get PDFAmordaad, Songs of Persia II, contains Persian songs written and performed by Dr. Khodadad (Khodi) Kaviani and Haideh Esfahani, with music composition by Saeed Shahram. Kaviani is an educator at Central Washington University, an author, poet, singer, and cultural diversity trainer. Through this music, Kaviani aims to introduce people to Iranian traditions that Zoroastrians have kept alive while providing Iranians the opportunity to reconnect with their cultural roots. This gift of cultural song is dedicated to all who appreciate the Iranian culture of peace, justice, and prosperity for all.
The name for this collection of songs--Amordaad--is the fifth month in the Iranian calendar. It means Immortal, signifying an attribute of the Creator. Each day in the Iranian calendar has a special name and, when it matches with the name of the month, Zoroastrians celebrate it. There are twelve such festivals in a year, including Norooz, Mehregaan, Teergaan, Sadeh, Chaahaar Shanbeh Soori, and Seezdab b-e Dar. The Amordaad Festival is celebrated on the day of Amordaad in the month of Amordaad. These traditions go back centuries and highlight the importance of celebrating life, liberty, justice, and happiness for all.https://digitalcommons.cwu.edu/kaviani/1001/thumbnail.jp
Wafer Level Packaging With Nano Metal Paste Interconnects For UV-C LEDs
No full text: Light emitting diodes (LEDs) have made remarkable progress since their invention and today they can be found in a wide range of applications such as TV remotes, automotive headlamps, general lighting, traffic signals, camera flashes, display and screens. LEDs that emit light in the ultraviolet-C (UV-C) range are used in applications such as air/water purification and sterilization. Cost per chip of these LEDs is relatively higher than the blue LEDs due to the expensive manufacturing process and low demand. But, the market for these LEDs in applications such as water purification is expected to grow in the coming years into a multimillion dollar market resulting in high volume manufacturing and low cost of chips. Consequently there will be a need for high volume and cost effective packaging solution with excellent thermal and optical performance. Existing packaging technologies like ceramic and lead frame packaging are expensive, less productive, and offer limited processing options. Meanwhile, wafer level packaging is a highly productive and cost-effective solution. Today, Silicon is the most common substrate of the integrated circuits. Moreover, its close coefficient of thermal expansion (CTE) with the LED base materials such as GaN and AlGaN, and the high thermal conductivity make it a good choice as a substrate of UV-C wafer level package. In this study we developed a silicon wafer level packaging approach combining advanced processes such as through silicon via (TSV) technology and chip to wafer (C2W) bonding for flip chip UV-C LEDs. We have integrated Si reflector cups for redirecting light from the sidewalls of UV-C LEDs using suitable material such as Aluminum. Complexities of a monolithic flow and the advantages of a dual wafer flow will be discussed. A new method to establish the interconnection in TSVs with metal nano pastes (MNPs) is introduced. The current vs voltage characteristics, optical performances, merits of reflectors, and improvements in spectral distributions of each package are measured and characterized. Different ways of bonding the chips to the submount and the thermal resistances of each package are studied. In conclusion we demonstrate the fabrication of a wafer level package for UV-C LEDs with a new cost effective TSV interconnection method using MNPs. We also show that sidewall emission of the LEDs is redirected with almost no loss in light which will be suitable for applications like water purification and protein analysis where the target doesn’t encapsulate the LED.Electrical Engineering, Mathematics and Computer ScienceElectronic Components, Technology and Material
The Effect of Low-Dose Ketamine in Treating Acute Asthma Attack; a Randomized Clinical Trial
Get PDFIntroduction: Efficient treatment of asthma can play an important role in controlling asthma attacks, rapid recovery and decrease of patient mortality. Therefore, in the present study the therapeutic effect of low-dose ketamine is evaluated in patients with acute asthma attack.
Methods: In the present single-blind, randomized clinical trial with placebo control, the effect of low-dose intravenous ketamine in treating 18 to 85 year-old asthmatic patients who presented to the emergency department was evaluated. Peak expiratory flow rate (PEFR) and the patients’ response to treatment were measured before and 1 hour after treatment. Additionally, using SPSS 22.0, effectiveness of ketamine with 0.3, 0.4, and 0.5 mg/kg doses followed by infusion of the same dose during 30 minutes were compared with placebo.
Results: 92 patients were enrolled (59.8% female, mean age 48.5 ± 13.9 years). 15 (16.3%) patients were treated with 0.3 mg/kg ketamine, 14 (15.2%) with 0.4 mg/kg, and 16 (17.4%) with 0.5 mg/kg doses. Mean PEFR was 336.2 ± 101.5 liters in the placebo group and 345.8 ± 84.7 liters in the ketamine group before intervention (p = 0.6), while after intervention, they were 352.1 ± 101.2 and 415.8 ± 76.2 liters, respectively (p = 0.001). Ketamine treatment with 0.4 and 0.5 mg/kg doses led to a higher increase in PEFR compared to 0.3mg/kg dose (df: 3, 88; F = 23.8; p < 0.001).
Conclusion: It seems that administration of 0.4 - 0.5 mg/kg doses of intravenous ketamine followed by infusion of the same dose during 30 minutes can be effective for rapid recovery of PEFR in patients with mild to moderate asthma

Data-Driven Stability Verification of Homogeneous Nonlinear Systems with Unknown Dynamics
No full textIn this work, we propose a data-driven approach for the stability analysis of discrete-time homogeneous nonlinear systems with unknown models. The proposed framework is based on constructing Lyapunov functions via a set of data, collected from trajectories of unknown systems, while providing an a-priori guaranteed confidence on the stability of the system. In our data-driven setting, we first cast the original stability problem as a robust optimization program (ROP). Since unknown models appear in the constraint of the proposed ROP, we collect a finite number of data from trajectories of unknown systems and provide two variants of scenario optimization program (SOP) associated to the original ROP. We discuss that the proposed ROP, and its corresponding SOPs, are not convex due to having a bilinearity between decision variables. We also show that while one of the proposed SOPs is more efficient in terms of computational complexity, the other one provides Lyapunov functions with a much better performance for the original ROP. We then establish a probabilistic closeness between the optimal value of (non-convex) SOP and that of ROP, and subsequently, formally provide the stability guarantee for unknown systems with a guaranteed confidence level. We illustrate the efficacy of our proposed results by applying them to two physical case studies with unknown dynamics including (i) a DC motor and (ii) a (homogeneous) nonlinear jet engine compressor. We collect data from trajectories of unknown systems and verify their global asymptotic stability (GAS) with desirable confidence levels.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Team Peyman Mohajerin Esfahan
