A bstract We have searched for axion-like resonance states by colliding optical photons in a focused laser field (creation beam) adding another (inducing stimulation of the decays, where frequency-converted signal can be created as result stimulated photon-photon scattering via exchanges resonances. quasi-parallel collision system (QPS) such allows access to sub-eV mass range particles. In past...

Humanoid robots are expected to both locomote and interact with objects within unstructured environments. A key component to realizing this goal is the ability for our algorithms to handle multiple contact switching scenarios within a whole-body control framework. To complement the many advances in trajectory optimization we must recognize which tools work best to robustly track these trajector...

Quadri-pulse stimulation (QPS), a type of repetitive transcranial magnetic (rTMS), can induce considerable aftereffect on cortical synapses. Human experiments have shown that the effect synaptic efficiency (in terms potentiation or depression) depends time interval between pulses. The maturation biophysically-based models, which describe physiological properties plasticity mathematically, offer...

In recent years, intelligent reflecting surface (IRS) has emerged as a promising technology for 6G due to its potential/ability significantly enhance energy- and spectrum-efficiency. To this end, it is crucial adjust the phases of elements IRS, most research works focus on how optimize/quantize phase different optimization objectives. particular, quantized shift (QPS) assumed be available at wh...

A compensation implementation scheme of the advanced targeting process based on fine tracking system is proposed in this paper. Based working quantum positioning (QPS) and its acquisition, pointing (ATP) system, subsystem ATP designed. six orbital parameters satellite Mozi, azimuth angle pitch are transformed into dynamic center system. The deviation analyzed. In Simulink, simulation experiment...

This paper presents an overview of the state art for safety-critical optimal control autonomous systems. Optimal methods are well studied, but become computationally infeasible real-time applications when there multiple hard safety constraints involved. To guarantee such constraints, it has been shown that optimizing quadratic costs while stabilizing affine systems to desired (sets of) states s...

این مقاله، روشی را برای کلاس‌بندی نوع مدولاسیون‌های دیجیتال از خانواده‌های ASK، PSK ، FSK، بدون اطلاعات قبلی از سیگنال دریافتی پیشنهاد می‌دهد. این روش دارای دو گام است و "روش خوشه‌بندی" نام دارد. در گام اول خانواده مدولاسیون و در گام دوم مرتبه‌ی مدولاسیون مشخص می‌شود. با استفاده از روش خوشه‌بندی، حداقل پیش‌پردازش‌ها، مؤثرترین ویژگی‌های جداسازی و مناسب‌ترین جداسازها در مورد هر دسته استفاده گردید...

در این تحقیق، توانایی روش طیف‌سنجی عدسی نورگرمایی با چیدمان دو لیزر پمپ و پروب پیوسته برای آشکارسازی مقادیر جزیی ناخالصی در آب مورد بررسی قرار گرفت. به این منظور، غلظت‌های مختلف یون آهن محلول در ترکیب چهار به یک آب و اتانول، مطالعه شد. جهت افزایش حساسیت روش از تقویت‌کننده قفل‌شونده و مدولاسیون شدت باریکه پمپ استفاده شد. همچنین، وابستگی شدت سیگنال نورگرمایی به‌دست آمده بر حسب فرکانس مدولاسیون با...

The planktonic ciliate Balanion masanensis n. sp. is described from living cells, from cells prepared by quantitative protargol staining (QPS), scanning electron microscopy (SEM), and transmitted electron microscopy (TEM) preparations, and the sequence of its nuclear small subunit rDNA (SSU rDNA) is reported. This species is almost ovoid with a flattened anterior oral region when the cells are ...
