Learning Objects Repositories are becoming increasingly available on the Internet. Learning Objects Pool (LOP) built around the “stock exchange” metaphor, brings a new concept of Learning Objects Repositories pushing users motivation to produce good LOs as well as increasing the cooperation between users, either by submitting suggestions and comments or rating existing LOs. To achieve such high...

One interpretation of levels of processing effects (LOP) on priming in implicit tests of memory is in terms of deficits in lexical processing during shallow study tasks. In two experiments the extent of lexical processing engaged in during standard shallow encoding tasks was manipulated by placing the encoding question either before or after the target stimulus. Clear evidence was found in expl...

In H.264, block-based discrete cosine transform (DCT) and blockbased motion compensated prediction are used to reduce both spatial and temporal redundancies. Due to the block-based coding, discontinuities at block boundaries, referred to blocking artifacts are created. To reduce these blocking artifacts, H.264 employs a deblocking filter. However, it causes a significant amount of complexity; t...

This paper is to examine Mandarin rhythm spoken in Taiwan. Oral recordings of twenty speakers who took the National Exam of Qualified Mandarin Teachers held in Taiwan in 2010. Based on the oral scores, they were evenly divided into two different groups: high oral proficiency (HOP) and low oral proficiency (LOP). Rhythmic correlates in sentence reading were analyzed from two perspectives: (a) pi...

Abstract Background Development of automatic, pneumatic tourniquet technology and use personalised pressures has improved the safety accuracy surgical systems. Personalisation pressure requires accurate measurement limb occlusion (LOP), which can be measured automatically through two different methods. The ‘embedded LOP’ method measures LOP using a dual-purpose cuff acting as both patient senso...

The linear ordering problem is an NP-hard problem that arises in a variety of applications. Due to its interest in practice, it has received considerable attention and a variety of algorithmic approaches to its solution have been proposed. In this paper we give a detailed search space analysis of available LOP benchmark instance classes that have been used in various researches. The large fitne...

In this paper, we present a multi-parent memetic algorithm (denoted by MPM) for solving the classic Linear Ordering Problem (LOP). The MPM algorithm integrates in particular a multi-parent recombination operator for generating offspring solutions and a distance-and-quality based criterion for pool updating. Our MPM algorithm is assessed on 8 sets of 484 widely used LOP instances and compared wi...

In this paper, we develop a new heuristic procedure for the linear ordering problem (LOP). This NP-hard problem has a significant number of applications in practice. The LOP, for example, is equivalent to the so-called triangulation problem for input-output tables in economics. In this paper we concentrate on matrices that arise in the context of this real-world application. The proposed algori...

We propose a new parameter for optimizing the performance of rateless codes by minimizing latency and data overhead. We call it Latency-Overhead Product (LOP). It is based on ideas used in the analysis of digital circuits. We demonstrate the effectiveness of the LOP parameter for a specific class of rateless codes called Online codes (OC). We give results from experiments in ideal channel and s...
