Internet of Things (IoT) involves processing massive data. This poses a huge challenge in the current computing systems due to the limited memory bandwidth. Processing in-memory (PIM) is a promising candidate to minimize this bottleneck and reduce the performance gap between processor and memory latency. We propose LUPIS (Latch-Up based Processing In-memory System) for nonvolatile memory (NVM)....

Off-line compilation of logic grammars using Magic allows an incorporation of filtering into the logic underlying the grammar. The explicit definite clause characterization of filtering resulting from Magic compilation allows processor independent and logically clean optimizations of dynamic bottom-up processing with respect to goal-directedness. Two filter optimizations based on the program tr...

Synchronous presentation of stimuli to the auditory and visual systems can modify the formation of a percept in either modality. For example, perception of auditory speech is improved when the speaker's facial articulatory movements are visible. Neural convergence onto multisensory sites exhibiting supra-additivity has been proposed as the principal mechanism for integration. Recent findings, h...

Chipita International, Inc., one of Greece’s largest manufacturers of bakery products and snacks, makes croissants on seven specialized processing lines in Lamia, Greece. A rise in the demand for croissants over the past years called for an increase in output. We undertook a project to determine cost-effective ways of speeding up the croissant-processing lines. We found that the efficiency of a...

We present the ‘online processing system’ version of Text-Induced Corpus Clean-up, a web service and application open for use to researchers. The system has over the past years been developed to provide mainly OCR error post-correction, but can just as fruitfully be employed to automatically correct texts for spelling errors, or to transcribe texts in an older spelling into the modern variant o...

In many real-life situations, uncertainty can be naturally described as a combination of several components, components which are described by probabilistic, fuzzy, interval, etc. granules. In such situations, to process this uncertainty, it is often beneficial to take this granularity into account by processing these granules separately and then combining the results. In this paper, we show th...

A hardware implementation of the pending interest table (PIT) for named data networking (NDN) is presented. One of the major challenges in this research is the per-packet update requirement in NDN packet processing. In general, the data structure of the lookup table is optimized in order to minimize the implementation cost and maximize the lookup performance. However, more computation steps are...

The fast increase in the size and number of databases demands data mining approaches that are scalable to large amounts of data. This has led to the exploration of parallel computing technologies in order to perform data mining tasks concurrently using several processors. Parallelization seems to be a natural and cost-effective way to scale up data mining technologies. One of the most important...

With the growing importance of XML in data exchange, much research has been done in proving flexible query mechanisms to extract data from structured XML documents. The semi-structured nature of XML data and the requirements on query flexibility pose unique challenges to database indexing methods. Recently, ViST that uses suffix tree and BTree was proposed to reduce the search time of the docum...
