Software inspections are a software engineering “best practice” for detecting and correcting defects in software artifacts, including requirements, design, code and test cases. Because defects are detected early in the software development process, software inspection improves software quality and reduces rework, thus saving time and costs. As a software process, inspections are adopted in many...

The introduction of High Definition Television (HDTV) asks for spatial up-conversion techniques in order to enable the displaying of standard definition material (SDTV). Recently, X. Li and M. Orchard proposed the “New Edge-Directed Interpolation” (NEDI) algorithm for high quality up-scaling of natural images. In this paper, we first analyze and evaluate this technique, and then propose a numbe...

The development of platforms able of handling transparently distribution, heterogeneity and multi-language software in the framework of an object model has been perceived as a promising direction to develop distributed applications. We wanted to develop a platform in which programmers of distributed applications could beneet from a coherent and uniform object model, as in traditional OO languag...

Dynamic topic models (DTMs) are very effective in discovering topics and capturing their evolution trends in time series data. To do posterior inference of DTMs, existing methods are all batch algorithms that scan the full dataset before each update of the model and make inexact variational approximations with mean-field assumptions. Due to a lack of a more scalable inference algorithm, despite...

The well-known radial graph layout technique has plenty of advantages for graph visualization and graph exploration, but is quite limited in the size of graphs it can display effectively because the layout is inherently global and allows far away or out of view nodes to distort the focus region. The primary contribution of this project is to introduce sub tree clustering to allow the layout alg...

Fresnel transform implementation methods using numerical preprocessing techniques are investigated in this paper. First, it is shown that up-sampling dramatically reduces the minimum reconstruction distance requirements and allows maximal signal recovery by eliminating aliasing artifacts which typically occur at distances much less than the Rayleigh range of the object. Second, zero-padding is ...

We define the notion of " projective " multiresolution analyses, for which, by definition, the initial space corresponds to a finitely generated projective module over the algebra C(T n) of continuous complex-valued functions on an n-torus. The case of ordinary multi-wavelets is that in which the projective module is actually free. We discuss the properties of projective multiresolution analyse...

Distributed and parallel processing of very large datasets has been employed for decades in specialized, high-budget settings, such as financial and petroleum industry applications. Recent years have brought dramatic progress in usability, cost effectiveness, and diversity of parallel computing platforms, with their popularity growing for a broad set of data analysis and machine learning tasks....

Metabolic rate, heart rate, lifespan, and many other physiological properties vary with body mass in systematic and interrelated ways. Present empirical data suggest that these scaling relationships take the form of power laws with exponents that are simple multiples of one quarter. A compelling explanation of this observation was put forward a decade ago by West, Brown, and Enquist (WBE). Thei...
