The substitution of diesel by cleaner renewable fuels such as short-chain alcohols in dual-fuel internal combustion engines is considered an attractive solution to reduce the pollutant emissions from engines. In this context, two-phase flow models for multi-component mixtures considering real-fluid thermodynamics are required further understanding evaporation and mixing processes transcritical ...

Two new apterous species of the genus Lathrobium Gravenhorst, 1802 from Fujian Province, East China, Lathrobium daocongchaoi Peng & Li, sp. n. and Lathrobium fujianense Peng & Li,sp. n., are described and illustrated.

A consistent thermodynamic model based on a combination of the Peng-Robinson equation state for gas components with an activity aqueous phase is utilized in this study to accurately evaluate performance geologic CO2 storage saline aquifers. To account thermal effects, enthalpy and conductivity are derived consideration dissolution brines. Several conceptual numerical setups variations parameter...

PENG Light is a controlled natural language designed to write unambiguous specifications that can be translated automatically via discourse representation structures into a formal target language. Instead of writing axioms in a formal language, an author writes a specification and the associated background axioms directly in controlled natural language. In this paper, we first review the contro...

Abstract Positive displacement expanders are widely investigated and theirs models commonly use the REFPROP database to evaluate fluid properties. However, estimating procedures in CFD using result heavy of CPU time. Therefore, a study has been carried out determine if simpler methods for property estimation suitable. The ANSYS CFX solver used includes number cubic equations state, namely, Redl...

background and purpose: highly consumption of antibiotics and their entrance into the environment has increased concerns all over the world. these compounds enter to the environment through an incomplete metabolism and a considerable amount of them cannot be removed using usual waste filtration systems. therefore, the present study aimed to investigate the feasibility of using ultraviolet radia...

In this paper we present PENG-D, a proposal for a controlled natural language that can be used for expressing knowledge about resources in the Semantic Web and for specifying ontologies in a human-readable way. After a brief overview of the main Semantic Web enabling technologies (and their deficiencies), we will show how statements and rules written in PENG-D are related to (a subset of) RDFS ...

In this case study we show how an unambiguous semantic representation can be constructed dynamically in left-to-right order while a text is written in PENG, a controlled natural language designed for knowledge representation. PENG can be used in contexts where precise texts (e.g. software specifications, axioms for formal ontologies, legal documents) need to be composed. Texts written in PENG l...

The combination of the piezoelectric materials and polymer is an effective way to make the piezoelectric nanogenerator (PENG) possess both the polymer's good flexibility and ferroelectric material's high piezoelectric coefficient. The volume ratio of ferroelectric material in the composite is an important factor that determines the PENG's output performance. In this paper, the BaTiO₃/polydimeth...
