We explore an opportunity to expand the stylistic variety of handmade and artisanal jigsaw puzzles through the appication of techniques from natural simulation. Typical jigsaw puzzle designs reflect the manufacturing constraints of die-cut, mass-production methods. We generate novel families of puzzle forms by applying a phase field approach to the simulation of dendritic solidification. We ext...

P-Jigsaw is an extension of W3C’s Jigsaw Web-server implementing a cache management strategy for replacement and pre-fetching based on association rules mining from the access-log.

Multi-touch technology has become increasingly popular interactive technology of teaching content. The displays with multi-touch are responsive enough to support a wide variety of applications. In this study, we attempt to apply three different technologies of C#, Microsoft Surface and Windows Presentation Foundation developing an interactive jigsaw game. This game would design with the multi-t...

Processes retrieve a variety of resources, such as files, from the operating system to function. However, securely accessing resources has proven to be a challenging task, accounting for 10-15% of vulnerabilities reported each year. Current defenses address only a subset of these vulnerabilities in ad-hoc and incomplete ways. In this paper, we provide a comprehensive defense against vulnerabili...

Shared last-level caches, widely used in chip-multiprocessors (CMPs), face two fundamental limitations. First, the latency and energy of shared caches degrade as the system scales up. Second, when multiple workloads share the CMP, they suffer from interference in shared cache accesses. Unfortunately, prior research addressing one issue either ignores or worsens the other: NUCA techniques reduce...

MOTIVATION Computational gene finding systems play an important role in finding new human genes, although no systems are yet accurate enough to predict all or even most protein-coding regions perfectly. Ab initio programs can be augmented by evidence such as expression data or protein sequence homology, which improves their performance. The amount of such evidence continues to grow, but computa...

An algorithm for assembling square jigsaw puzzles is presented. We commence by introducing criteria that govern the selection of proper jigsaw puzzle solving method for a given application. Our algorithm uses the gray level profiles of border pixels for local matching of the puzzle pieces. Unlike the classical best-first search, the algorithm simultaneously locates the neighbors of a puzzle pie...

BACKGROUND Neurocognitive disorders are an important societal challenge and the need for early prevention is increasingly recognized. Meta-analyses show beneficial effects of cognitive activities on cognition. However, high financial costs, low intrinsic motivation, logistic challenges of group-based activities, or the need to operate digital devices prevent their widespread application in clin...

This paper compared two collaborative activities for college students' integration of research pieces of cognitive science. One is the jigsaw method that assigns different pieces to different students and makes them exchange what they learn. The other is a simpler type of collaboration that gives all pieces to all students in a serial order. Comparing the results, we found that the jigsaw promo...
