یکی از مهم ترین مشکلات سیستم های ofdm عدم توانایی این سیستم ها در حذف سیگنال تداخل در باند فرکانسی سیگنال مطلوب می باشد. برای حذف این تداخلات از روش های شکل دهی پرتو استفاده می شود. دو روش مرسوم شکل دهی پرتو، روش pre-fft (شکل دهی پرتو در حوزه زمان) و روش post-fft (شکل دهی پرتو در حوزه فرکانس) می باشند. برای به روزرسانی وزن ها در هر دو روش راه حل های مختلفی پیشنهاد شده است که می توان همه آن ها ر...
Cloud services provide a powerful resource to which weak clients may outsource their computation. While tremendously useful, they come with their own security challenges. One of the fundamental issues in cloud computation is: how does a client efficiently verify the correctness of computation performed on an untrusted server? Furthermore, how can the client be assured that the server learns not...
Reinforcement learning is based on exploration of the environment and receiving reward that indicates which actions taken by the agent are good and which ones are bad. In many applications receiving even the first reward may require long exploration, during which the agent has no information about its progress. This paper presents an approach that makes it possible to use pre-existing knowledge...
Generative Adversarial Networks (GANs) have shown great promise recently in image generation. Training GANs for text generation has proven to be more difficult, because of the non-differentiable nature of generating text with recurrent neural networks. Consequently, past work has either resorted to pre-training with maximumlikelihood or used convolutional networks for generation. In this work, ...
the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
Background Pre-eclampsia is one of the main causes of morbidity and mortality among pregnant women. This study was done with the objective of measuring abdominal aorta intima-media thickness, serum level of leptin, and lipid profile in neonates of pre-eclampsia mothers and comparing them with neonates of mothers without pre-eclampsia (control group). Materials and Methods Ninety neonates of pre...
To evaluate the effect of seed pre-soaking on forage yield and quality and water productivity in late planting of two forage sorghum cultivars, a field experiment was conducted was conducted as split factorial arrangements in randomized complete block design with three replications in 2017 and 2018 growing seasons at the research field of Seed and Plant Improvement Institute, Karaj, Iran. Four ...
