An image coding algorithm, PROGRES (Progressive Resolution Coding), for a high speed resolution scalable decoding is proposed. The algorithm is designed based on a prediction of the decaying dynamic ranges of wavelet subbands. Most interestingly, because of the syntactic relationship between two coders, the proposed method costs very similar amount of bits as used by uncoded (i.e. not entropy c...

We consider the problem of private information retrieval (PIR) from N non-colluding and replicated databases, when the user is equipped with a cache that holds an uncoded fraction r from each of the K stored messages in the databases. This model operates in a two-phase scheme, namely, the prefetching phase where the user acquires side information and the retrieval phase where the user privately...

A centralized coded caching scheme has been proposed by Maddah-Ali and Niesen to reduce the worst-case load of a network consisting of a server with access to N files and connected through a shared link to K users, each equipped with a cache of size M . However, this centralized coded caching scheme is not able to take advantage of a non-uniform, possibly very skewed, file popularity distributi...

This paper presents robust methods for determining the order of a sequence of stripes captured in an uncoded structured light scanning system, i.e. where all the stripes are projected with uniform colour, width and spacing. A single bitmap image shows a pattern of vertical stripes from a projected source, which are deformed by the surface of the target object. If a correspondence can be determi...

The number of uncoded (non-coding; nc) RNAs with unknown functions is increasing. Since their first detections especially miRNA ncRNAs have become very important. In fact, importance has been well understood and relations diseases are more evident. It clear that they can be used in the diagnosis most future. Northern hybridization, flow cytometry, cloning, qPCR, sequencing microarray analysis f...

this study aimed at investigating the effect of learners’ gender on their preferences for corrective feedback. learners’ prefer- ences which were investigated included the necessity, frequency, timing, type, method, and delivering agent of error treatment. to this end, a questionnaire was administered to a random sample of 100 participants (50 males and 50 females) studying english (efl) at shi...

introduction: feedback is very important in education and can help quality in the training process and orient the trainees in clinical contexts. this study aimed to assess the residents’ points of view about feedback in clinical education at shiraz university of medical sciences. methods: the sample of this study included 170 medical residents attending medical workshops in shiraz university of...

recent interaction studies havefocused on the relationship between interactional feedback and l2 development.despite the large body of knowledge in this regard, few studies have examinedlearners’ preferences for interactional feedback. besides, different findingshave been reported concerning learners’ preferences for feedback and none hasexamined the factors accounting for the variation in the ...
