Abstract. Urban heat island (UHI) and urban air pollution are two major environmental problems faced by many metropolises. The UHI affects changing the local circulation chemical reaction environment, e.g. temperature relative humidity. In this study, WRF-CMAQ (Weather Research Forecasting Community Multiscale Air Quality) model was used to investigate impact of an on vertical distribution aero...

Requirements on subsystems have been made clear in this paper for a linear time invariant (LTI) networked dynamic system (NDS), under which subsystem interconnections can be estimated from external output measurements. In NDS, may distinctive dynamics, and are arbitrary. It is assumed that matrices of each depend its (pseudo) first principle parameters (FPPs) through fractional transformation (...

For f : [0, 1]→ R, we consider Lft , the local time of spacetime Brownian motion on the curve f . Let Sα be the class of all functions whose Hölder norm of order α is less than or equal to 1. We show that the supremum of Lf1 over f in Sα is finite is α > 12 and infinite if α < 1 2 . Abstrait: Soit Wt un mouvement brownien et soit L f t le temps local du processus (t,Wt) pour le courbe f : [0, 1...

Centralized wide area control design using systemwide data has been suggested to enhance large interconnected power systems dynamic performance. Because of the nature of wide area interconnections, communication delay cannot be ignored in the wide area control. A long time delay may cause a detrimental effect to system stability and degrade system robustness. The general Linear Fractional Trans...

background: celiac disease (cd) has been found in up to 10% of the patients presenting with unexplained abnormal liver function tests (lft). as there is no precise data from our country in this regard, we investigated the prevalence of cd in patients presenting with abnormal lft. methods: from 2003 to 2008, we measured iga anti-tissue transglutaminase (t-tg) antibody (with elisa technique) with...

UNLABELLED Reflexologists claim that massage to specific points of the feet increases blood supply to internal organs. This study measured changes in cardiovascular parameters in subjects receiving reflexology to areas of their feet thought to correspond to the heart (intervention) compared with other areas which are not (control). METHOD 16 reflexology-naive healthy volunteers received an ac...

INTRODUCTION SUMMARY We present an exact and analytical expression for the Fourier transform of a function that has been sampled logarithmically. The procedure is significantly more efficient computationally than the fast Fourier transformation (FFT) for transforming functions or measured responses which decay slowly with increasing abscissa value. We illustrate the proposed method with an exam...

Melemahnya harga karet alam dan kelangkaan penyadap merupakan masalah utama yang dihadapi perusahaan perkebunan dalam satu dasawarsa terakhir. Merebaknya penyakit gugur daun Pestalotiopsis membuat langkah-langkah peningkatan produktivitas menjadi sulit dicapai. Upaya efisiensi biaya adalah strategi harus dilakukan untuk mempertahankan performa saat ini. Sistem sadap frekuensi rendah atau low fr...
