The Jigsaw is a cooperative learning technique in which the class is first divided into expert groups that are assigned different but related tasks. New “home” groups consisting of one memb er from each expert group are then formed. Each expert instructs the other members of this new group about what they have learned. In our application of the jigsaw, we use the expert groups to give students ...

Program composition and compositional proof systems have proven them­ selves important for simplifying the design and the verification of programs. The paper presents a version of the jigsaw program composition operator pre­ viously defined in [FFG90, FFG91]. Here, the jigsaw operator is defined as the unification of its components by their most general unifier. The jigsaw operator generalizes ...

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...

In this paper, we consider the square jigsaw puzzle problem in which one is required to reassemble the complete image from a number of unordered square puzzle pieces. Here we focus on the special case where both location and orientation of each piece are unknown. We propose a new automatic solver for such problem without assuming prior knowledge about the original image or its dimensions. We us...

We present a new technique to produce composite images called Puzzle Image Mosaic (PIM). The method is inspired by Jigsaw Image Mosaic (JIM), where image tiles of arbitrary shape are used to compose the final picture. The JIM approach leads to impressive results, but the required computation time is high. We propose an algorithm that produces good results in lower time. The technique takes adva...

Jigsaw cooperative learning is a model that encourages active students and helps each other in mastering the subject matter by dividing it into groups of origin experts teaching activities. Each group responsible for material or subject. After expert has finished studying one topic their expertise, student returns to home teach expertise friends discussion group. The aim study was test whether ...

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...

Introduction: In Pharmacy Diploma Program, mathematics is known as pharmaceutical mathematics. Due to the importance of pharmaceutical mathematics in practice, it is important to have a basic mathematical skill as a basis in calculations in pharmaceutical science. Therefore, it is necessary to create a lecturing condition that enables students more active in understanding the lessons. This rese...
