Most teachers give written feedback because it is a required deliverable, like a checkout assistant handing every customer the printed receipt, even though few use them. However there is no point in giving feedback unless the learner uses it: modifies or actively reappraises something specific as a result. This paper explores the theoretical and practical implications of taking this as the star...

Overlap function (which has symmetry and continuity) is widely used in image processing, data classification, multi-attribute decision making problems. In recent years, theoretical research on overlap been extended to interval valued lattice function, but intuitionistic fuzzy (IF-overlap function) not studied. this paper, the concept of IF-overlap proposed for first time, then generating method...

Follow-the-Leader (FTL) is an intuitive sequential prediction strategy that guarantees constant regret in the stochastic setting, but has poor performance for worst-case data. Other hedging strategies have better worst-case guarantees but may perform much worse than FTL if the data are not maximally adversarial. We introduce the FlipFlop algorithm, which is the first method that provably combin...

مسیر تحولی و جایگزینی قطعات آنالوگ با دیجیتال، گیرنده های مخابراتی را نیز در برگرفته است. با توجه به پیشرفت سریع تکنولوژی و ظهور بیشتر استانداردهای مخابرات سیار و همزیستی آن ها در سراسر جهان، یک گیرنده رادیویی چندحالته قطعا یک مزیت قابل توجه به حساب می آید. به همین دلیل در چندسال اخیر تحقیقات گسترده ای در زمینه طراحی و ساخت رادیوهای نرم افزاری صورت گرفته است. در این سیستم ها سعی شده است حتی الم...

Geo-replicated storage systems are at the core of current Internet services. Unfortunately, there exists a fundamental tension between consistency and performance for offering scalable geo-replication. Weakening consistency semantics leads to less coordination and consequently a good user experience, but it may introduce anomalies such as state divergence and invariant violation. In contrast, m...
