Abstract In 2006, K. Feng, L. Xu and F. J. Hickernell initiated the concept of a linear error-block code which is a natural generalization of the classical linear code. In this correspondence, we investigate optimal linear errorblock codes in two directions: maximal dimension codes and maximal minimum π-distance codes. First perspective on optimizing a code is by studying lower bounds and upper...

Aim at solving the existing problems of 3D model retrieval based on neural network, this paper proposes a new algorithm based on BP-bagging. Through bagging, the algorithm turns the weak classifier into the strong. As to feature extraction, the algorithm projections 3D model into six 2D images by six perspective points. Then transforms the images into frequency domain, gets the high dimension f...

1. Introduction Crime has been shown to exhibit marked variations over both space and time. Sherman (1989) reported that 3% of addresses are the subject of 50% of police call for service (Sherman, 1989 p.3). This is also the case with the temporal dimension; Van Koppen (1999) in his study of commercial robberies reported daily and weekly peaks and distinct increases in winter rather than in sum...

This paper continues the study of the Gregory-Laflamme instability of black strings, or more precisely of the order of the transition, being either first or second order, and the critical dimension which separates the two cases. First, we describe a novel method based on the Landau-Ginzburg perspective for the thermodynamics that somewhat improves the existing techniques. Second, we generalize ...

Since innovation plays an important role in the context of food, as evident in how successful chefs, restaurants or cuisines in general evolve over time, we were interested in exploring this dimension from a more virtual perspective. In particular, the paper presents results of a study that was conducted in the context of a large-scale German online food community forum to explore another impor...

When Information Technology (IT) Innovations become Disruptive Innovations (DI), they bring along with them a dimension of “wicked problems” due to their disruptive attributes; they however, concurrently usher in an “empowerment opportunity” due to the typical nature of advances in IT. The session would explore the opportunities that this phenomenon holds for both “Blue Ocean” research and prac...

This paper organizes a variety of existing strategy theories, typologies and models into a framework that can be used to analyze and validate the investment thesis for a proposed acquisition by a strategic or corporate buyer. One dimension of the framework utilizes the classical models and theories of strategy. A second dimension applies models that were developed to understand M&A value creati...

Starting from an ontology draft which reflects the intended modeling perspective, the ontology engineer can be supported by suggesting similar already existing sub-ontologies and ways for integrating them with the existing draft ontology. Our approach combines syntactic, linguistic, structural and logical methods into an innovative modelingperspective aware solution for detecting matchings betw...

To address complexity of modeling the world’s processes, over the years in different scientific disciplines separation assumptions have been made to isolate parts of processes, and in some disciplines they have turned out quite useful. It can be questioned whether such assumptions are adequate to address complexity of integrated human mental and social processes and their interactions. In this ...
