We introduce the SCP the sorted common prefix, and study some of its properties. Based on the internal representations used by a class of new compression schemes, we show how the SCP table can be constructed using an ( ) max κ Σ + u O number of comparisons on average, and ( ) Σ u O worst case, where u is the size of the sequence, Σ is the number of symbols, and max κ is the maximum SCP value. W...

ÐMany recent studies [8], [10] have suggested that the optimistic concurrency control (OCC) protocols outperform the locking-based protocols in real-time database systems (RTDBS). However, the OCC protocols suffer from the problem of unnecessary transaction restarts that is detrimental to transactions meeting their deadlines. The problem is more intensified in mixed transaction environments whe...

the properties of alkaline sulfite anthraquinone (as/aq) pulp from old corrugated container (occ)was studied. in each trial 100 grams (based on dry weigth) of occ and 18% active alkali was used.three levels of anthraquinone (0.0.1 and 0.2% based on dry weigth of the occ) and two pulpingtimes (120 and 150 minutes at maximum pulping temperature) were applied. pulping temperature,na2so3/naoh ratio...

This study attempts to investigate sociotechnical gaps in online collaborative consumption (OCC) to improve user experience and provide better design requirements. A new approach is proposed to evaluate usability and sociability of the OCC communities. The formation of social capital within OCC will also be studied to gain insights into design requirements. Due to its features as a community wh...

A multi-set of N strings of length n is called a multi-track string. The permuted pattern matching is the problem that given two multi-track strings T = {t1, . . . , tN} of length n and P = {p1, . . . , pN} of length m, outputs all positions i such that {p1, . . . , pN} = {t1[i : i+m−1], . . . , tN [i : i+m−1]}We propose two new indexing structures for multi-track stings. One is a time-efficien...

This work proposes using the changes in LEDs' spectral emission induced by temperature variations to implement emitters for new communication channels Optical Camera Communication (OCC) systems. If a camera can discriminate shift response, these modifications be contemplated as data channel. The main advantage is that obtained from same physical optical emitter device, only are needed. Thus, th...

In the path minimum query problem, we preprocess a tree on n weighted nodes, such that given an arbitrary path, we can locate the node with the smallest weight along this path. We design novel succinct indices for this problem; one of our index structures supports queries in O(α(m,n)) time, and occupiesO(m) bits of space in addition to the space required for the input tree, where m is an intege...

The Wnt signaling pathway is hyperactivated in most colorectal cancers (CRC). Finding new regulators of this pathway represents the potential for cancer diagnosis or treatment. OCC-1 was initially reported as an up-regulated gene in colon carcinoma, without knowing its mechanism of action. Here, two novel transcript variants and an exonic microRNA that originated from the OCC-1 gene are reporte...

Error Tree is a novel tree structure that is mainly oriented to solve the approximate pattern matching problems, Hamming and edit distances, as well as the wildcards matching problem. The input is a text of length n over a fixed alphabet of length Σ, a pattern of length m, and k. The output is to find all positions that have ≤ k Hamming distance, edit distance, or wildcards matching with P . Th...

Novelty detection involves modeling the normal patterns for detecting any divergence from this behavior. Our recently proposed algorithm, Glabal&Local One Class Classifier (GLocal OCC), can solve this problem by maximizing the margin between the hyperplane and the origin through embedding the global information into the OCSVM framework. In this paper, we propose Linear Programming (LP) GLocal O...
