Many-core architectures are a commercial reality, but programming them efficiently is still a challenge, especially if the mix is heterogeneous. Here granularity must be addressed, i.e. when to make use of concurrency resources and when not to. We have designed a data-driven, fine-grained concurrent execution model (SVP) that captures concurrency in a resource-agnostic way. Our approach separat...

A company needs to implement several make-to-stock policies apart from a regular make-to-order production, so that the capacity of expensive resources can be fully utilized. The constraints to be considered in such capacity planning problem include finite budget for investing resources, lump demands of customers, decline of products price with time, different product mix for simultaneous manufa...

We extend the original cylinder conjecture on point sets in affine three-dimensional space to more general framework of divisible linear codes over $\mathbb{F}_q$ and their classification. Through a mix programming, combinatorial techniques computer enumeration, we investigate structural properties these codes. In this way, can prove reduction theorem for generalization conjecture, show some in...

In many ways it is a unique challenge to teach programming and high-level application development to noncomputer science majors like information systems. Simple visual computing can be a very helpful tool in such situations because it enables programs to produce something students can see. This paper describes a semesterlong experience of using image-processing as the theme in a course to teach...

An optimal maintenance strategy mix is necessary for increasing availability and reliability levels of production facilities without significantly increasing operational costs. The selection of maintenance strategies is a typical Multiple Criteria Decision-Making (MCDM) problem with conflicting goals. Consideration of interdependence among the criteria and alternative policies for maintenance s...

Splotch is a rendering algorithm for exploration and visual discovery in particlebased datasets coming from astronomical observations or numerical simulations. The strengths of the approach are production of high quality imagery and support for very large-scale datasets through an effective mix of the OpenMP and MPI parallel programming paradigms. This article reports our experiences in re-desi...

The symmetric multiprocessing (SMP) cluster system, which consists of shared memory nodes with several multicore central processing units connected to a high-speed network to form a distributed memory system, is the most widely available hardware architecture for the high-performance computing community. Today, the Message Passing Interface (MPI) is the most widely used parallel programming par...

In this paper we introduce AR Scratch, the first augmented-reality (AR) authoring environment designed for children. By adding augmented-reality functionality to the Scratch programming platform, this environment allows pre-teens to create programs that mix real and virtual spaces. Children can display virtual objects on a real-world space seen through a camera, and they can control the virtual...

The urban planning is required to direct the cities development based on the sustainable use of its territory. On the other hand, Answer Set Programming (ASP) is a logic programming paradigm with the ability of non-monotonic reasoning, which has contributed to solving complex problems in a short period of time, providing a considerable number of possible outcomes to the same problem. The treatm...
