ODMG and SQL object models ten years later: there are no contradictions

open access: yesТруды Института системного программирования РАН, 2018
In 2005, I wrote an article in which I discussed the most important features of the standards ODMG 3.0 (ODMG object model) and the SQL:2003 (SQL data model) and convincingly (as it seemed to me) argued that the similarity between the object model and ...

Web applications and data: achieving abstraction and scalability

open access: yesТруды Института системного программирования РАН, 2018
Nowadays it has become clear that no data store is all-purpose. SQL-based systems have been prevalent for several decades though this approach leads to serious issues in modern high scalability architectures.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Ranking of Illegal Buildings Close to Rivers: A Proposal, Its Implementation and Preliminary Validation

open access: yesISPRS International Journal of Geo-Information, 2019
Illegal buildings (IBs) are a dramatic problem in developing countries due to the population explosion, but, at the same time, they represent an unsolved issue in several states usually called advanced (as, for instance, Italy).

2D MOF with Intrinsic Porosity for Colorimetric Volatile Organic Compounds (VOCs) Detection

open access: yesAdvanced Materials, EarlyView.
An uncommon 2D MOF with intrinsic in‐plane porosity that can be mechanically exfoliated undergoes a distinct and reversible colour change upon exposure to various volatile organic compounds. ABSTRACT In this work, we report an uncommon 2D metal–organic framework (MOF) with intrinsic in‐plane porosity that undergoes a distinct and reversible colour ...

Modulating the Charge Transfer Channels via Constructing Charge‐Assisted Hydrogen‐Bonded Organic Frameworks for Enhanced Photosynthesis of Hydrogen Peroxide

open access: yesAdvanced Science, EarlyView.
This work reports a strategy of engineering charge‐assisted hydrogen bonds to tailor charge transfer channels in HOFs, significantly improving their performance in photocatalytic H2O2 production. ABSTRACT The production of H2O2 via artificial photosynthesis is often limited by inefficient charge‐carrier separation, causing significant charge ...
