The public package registry npm is one of the biggest software registry. With its 216 911 software packages, it forms a big network of software dependencies. In this paper we evaluate various methods for finding similar packages in the npm network, using only the structure of the graph. Namely, we want to find a way of categorizing similar packages, which would be useful for recommendation syst...

The SOA Innovation Lab has investigated the use of standard software packages in a service-oriented context. As a result, we present a holistic approach for developing a service-oriented enterprise architecture with custom and standard software packages. It starts on enterprise level with the identification of domains where both the SOA paradigm and standard software are of relevance. Here SOA ...

Though there are now many software packages that can develop urban delivery schedules, there is a reluctance on the part of those involved with the management of the transportation systems to use automatic vehicle scheduling packages" The lack of confidence in such packages is, in part, the result of several failed implementation attempts, These failures can often be attributed to factors such ...

We briefly discuss software packages for the analysis of molecular ecological data, focusing on three levels of analysis: parentage and relatedness, population genetic structure, and phylogeny reconstruction. For the first two levels of analysis, we have gathered lists of some of the packages that we consider to be the most useful and user-friendly. For each package, we provide information on n...

This paper relates the Defense Acquisition University defined systems engineering process to zonal ship design at the concept and feasibility design level. In particular, it describes an effective way of capturing a complete set of customer requirements based on the Universal Navy Task List (UNTL) and allocating these required functions to system packages comprised of hardware, software, and ma...

We have compared current image analysis software packages in order to find the most useful one for assessing microbial adhesion and inhibition of adhesion to tissue sections. We have used organisms of different sizes, the bacterium Helicobacter pylori and the yeast Candida albicans. Adhesion of FITC-labelled H. pylori and C. albicans was assessed by confocal microscopy. Four different Image ana...

The article is devoted to the comparative analysis of software packages in financial time series modeling. The most common among economists packages R, Eviews and Gretl are considered. Volatility is often used as a rough approximation to measuring of overall risk financial instruments. Polish stock index WIG for the modeling of financial time series volatility was chosen. Econometric model of f...

The rise of user-contributed Open Source Software (OSS) ecosystems demonstrate their prevalence in the software engineering discipline. Libraries work together by depending on each other across the ecosystem. From these ecosystems emerges a minimized library called a micro-package. Micropackages become problematic when breaks in a critical ecosystem dependency ripples its effects to unsuspectin...

Introduction: This study was aimed to investigate the beneficial effects of functional magnetic resonance imaging (fMRI) data in treatment planning for patients with CNS tumors in order to decrease the injury of functional regions of the brain followed by increase in life quality and survival of patients. This study pursues a novel approach in planning for the treatment of brai...
