The influences of nanosilica and modified on cure, compression set, mechanical swelling characteristics are studied in blends ethylene-propylene-diene monomer (EPDM)/styrene-butadiene rubber (SBR). In EPDM/SBR composites, the made from rice husk ash (RHA) was utilised as a reinforcing nanofiller. interaction between matrix at interface is crucial for production composites. This study uses bis[3...

The use of adequate thermal energy storage (TES) systems has shown the potential to increase efficiency in many fields, such as building sector. Shape-stabilized phase change materials (SS-PCMs) have attracted attention address one key barriers (PCMs), leakage during liquid state, that nowadays limits its applicability. However, SS-PCMs still drawbacks overcome, poor fire reaction and stability...

In some phases of system development state-based methods are adequate; in others event-based methods are adequate. Petri nets provide a system model which supports both methods and thus allow a smooth transition between the diierent phases of system development. Most temporal logics for Petri nets, however, do not support both methods. In this paper we introduce a temporal logic for Petri nets ...

In this work, we present crack propagation experiments evaluated by digital image correlation (DIC) for a carbon black filled ethylene propylene diene monomer rubber (EPDM) and numerical modeling with the help of variational phase-field fracture. Our main focus is evolution cracks in one-sided notched EPDM strips containing circular hole. The are complemented investigations identifying mechanic...

BACKGROUND This study aimed at determining the prevalence of malaria and anemia among children in rural community of Okada, Edo State Nigeria, as well as to assess the level of use of Insecticide treated bed nets and its impact on prevalence of malaria and anemia among study population. METHODS Thick blood films from 226 children with signs and symptoms of malaria in Okada community were stai...

Logic Petri nets (LPNs) can describe and analyze batch processing functions and passing value indeterminacy in cooperative systems. Logic Petri workflow nets (LPWNs) are proposed based on LPNs in this paper. Process mining is regarded as an important bridge between modeling and analysis of data mining and business process. Workflow nets (WF-nets) are the extension to Petri nets (PNs), and have ...
