uct was obtained under the same PCR conditions as those used for A. argenteus. However, three primer sets (MSAA-3, MSAA-4 and MSAA-6) gave PCR products in the amplification using low annealing temperatures at 45 ¡C, 35 ¡C and 40 ¡C, respectively, although the remaining sets did not provide any products even at the low annealing temperatures (e.g. 10 ¡C below the annealing temperature in Table 1...

We describe a simple extension for MSAA to ray tracing and describe how to integrate motion blur with MSAA. We show that MSAA extends naturally to a ray tracer, but it does not integrate well with motion blur. To solve this problem, we add a cache to help reduce unnecessary shading. We then show that the quality and performance of our MSAA + motion blur solution makes it worthwhile for many ray...

The modulated scattering antenna array (MSAA) is composed of one normal antenna element and several modulated scattering elements (MSEs). In this report, a 2-element MSAA is used as the receiving antenna in 2 × 2 multiple input multiple output (MIMO) system. MIMO performance of MSAA with various array spacing is measured to investigate the relation between the array spacing and the MIMO perform...

The modulated scattering array antenna (MSAA) is composed of one normal antenna element and several modulated scattering elements (MSE). In this report, a 2-element MSAA is used as the receiving antenna in a 2 by 2 multiple input multiple output (MIMO) system. The MIMO performance of the MSAA with various array spacing is measured to investigate experimentally the relation between the array spa...

ساختار ll-sst (low-low satellite-to-satellite tracking) اولین بار با پرتاب ماهواره grace (gravity recovery and climate experiment) در 2002 اجرایی شد. برای رسیدن به دقت و حساسیت بیشتر در بازیابی میدان جاذبه زمین در مقیاس جهانی می توان ساختار ll-sst را با ساختار hl-sst (high-low satellite-to-satellite tracking)که قبلاً در ماهواره champ (challenging minisatellite payload) استفاده شده ترکیب کرد. اخت...

1 Introduction The previous researches on the modulated scattering antenna array (MSAA) have shown that the second-order intermodulation scattering signal is relatively low compared with the direct received signal [1]. In this report, a switched reflector is used to solve this problem. The diversity performance of the MSAA with a switched reflector is investigated. It is shown that the diversit...

The multiple-input multiple-output (MIMO) performance of the modulated scattering antenna array (MSAA) is analyzed numerically for the first time in indoor environment based on an approach to hybridization of the Volterra series method and method of moments (MoM) in this letter. Mutual coupling effect between the Modulated scattering element (MSE) and the normal antenna element is also consider...

The diversity performance of the modurated scattering array antenna (MSAA) with various array spacing is measured in Rayleigh fading environment to investigate experimentally the relation between the array spacing and the diversity performance of the MSAA. A 2-element modulated scattering monopole array antenna with various array spacing which is supposed to be used for mobile handset applicati...

A total of 172 sera from patients with multiple sclerosis (MS), theri relatives and nursing personnel, patients with other neurological and nonneurological diseases, and healthy donors living in the United State or East Africa under vastly divergent hygienic conditions were examined for their capacity to neutralize the MS-associated agent (MSAA), which induces in experimental animals a transito...

In this paper a novel Modified Simulated Annealing Algorithm (MSAA) is used as global optimization technique to find the solution of combinatorial optimization problem which is usually difficult to tackle. MSAA combines good methodologies like global minimum converging property of Simulated Annealing algorithm and fast convergence rate of Hamming scan algorithm. Orthogonal Netted Radar System (...
