Parallel MRI for Regridding Multi-Shot Diffusion Data
INTRODUCTION A single shot EPI readout is commonly used in diffusion weighted imaging to avoid motion artefacts. Signal decay restricts the echo train length and this limits resolution. Furthermore, the small phase encode bandwidth leads to susceptibility artefacts. Parallel MRI enables image reconstruction from an acquisition with phase encodes omitted and this allows a shorter echo train leng...

متن کاملinvestigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances
در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
Multi-Purpose Mobile Artefacts
Paper-based artefacts (e.g., forms, manuals, questionnaires) are used ubiquitously and pervasively to support a wide set of activities. Education and Health Care are major examples of such endeavour. However, given the passiveness of the medium itself, several problems (e.g., communication, adjustment, lack of interactivity) are usually encountered within these activities which hinder human eff...
متن کاملFast Vortex Methods
We present three fast adaptive vortex methods for the 2D Eu-ler equations. All obtain long-time accuracy at almost optimal cost by using four tools: adaptive quadrature, free-Lagrangian formulation, the fast multipole method and a nonstandard error analysis. Our error analysis halves the diierentiability required of the ow, suggests an eecient new balance of smoothing parameters , and combines ...
