This short note points out an improvement on the robust stability analysis for electrically driven robots given in the paper. In the paper, the author presents a FAT-based direct adaptive control scheme for electrically driven robots in presence of nonlinearities associated with actuator input constraints. However, he offers not suitable stability analysis for the closed-loop system. In other w...

Many prior efforts have suggested that Internet video Quality of Experience (QoE) could be dramatically improved by using data-driven prediction of video quality for different choices (e.g., CDN or bitrate) to make optimal decisions. However, building such a prediction system is challenging on two fronts. First, the relationships between video quality and observed session features can be quite ...

In this paper the relationships between crude oil and refined product prices are investigated in a multivariate framework. This allows us to test several (partly competing) assumptions of earlier studies. In particular, we find that the crude oil price is weakly exogenous and that the spread is constant in some but not all relationships. Moreover, the multivariate analysis shows that the link b...

The NSDL Materials Digital Library Pathway (MatDL) is utilizing a wiki to facilitate the expert community-driven development of a controlled vocabulary on assembly of nanosystems. Vocabulary development is being initiated using preferred subject terms gathered from Dublin Core metadata captured during the execution of nanoscale computer simulation codes of a research group whose members are def...

Mechanisms for controlling object freshness and refresh by are examined. Preliminary trace-driven analysis is preformed to explore object freshness relationships, a possible means of optimizing them based on traffic characteristics is introduced, and possible modifications to current mechanisms are contemplated.

The enterprise software need adapt to new requirements from the continuous change management. The recent development methods have increased the flexibility of software. However, previous studies have ignored the stability of business object and the particular business relationships to support the software development. In this paper, a coarse-grained business object based software development, B...

Overwash is a physical process of coastal sediment transport driven by storm events and is essential to landscape resilience in low-lying barrier environments. This work establishes a comprehensive set of scaling laws for overwash morphology: unifying quantitative descriptions with which to compare overwash features by their morphological attributes across case examples. Such scaling laws also ...

Mutual relationships of human endogenous retroviruses (HERVs) and their similarities to other DNA elements are studied in this paper. We demonstrate that a completely data-driven grouping is able to reflect same kinds of relationships as more traditional biological classifications and phylogenetic taxonomies. The clusters and their visualization were computed with the Median Self-Organizing Map...

currently, outsourcing is recognized as one of the useful strategies in the world of business. in this respect, business processes outsourcing is one of the most common forms of outsourcing. the purpose of the present study is to provide a multi attribute decision making model in order to outsource the process of azin-tane company. to this end, 19 effective attributes were driven after doing in...

Previous computer simulations of multiple 10 keV Si cascades in 3C–SiC demonstrated that many damage-state properties exhibit relatively smooth, but noticeably different, dose dependencies. A more recent analysis of these damage-state properties, which includes additional data at low and intermediate doses, reveals more complex relationships between system energy, swelling, energy per defect, r...
