In this paper, numerical simulations have been performed to study the performance of a single fully activated flapping wing serving as energy harvester. The aims paper are predicting and maximizing extraction efficiency by using optimization methodology. metamodeling genetic algorithms applied in order find optimal configuration improving efficiency. A response surface method (RSM) based on Box...

The kaolin suspension calcination technology is currently gaining attention as a new process of calcining kaolin. In this paper, the cooling system designed by CBMI Construction Co., Ltd. simulated using ANSYS Fluent software to analyze velocity field and temperature gas–solid two-phase flow Eulerian model. A compiled UDF (User-Defined Function) used simulate transfer mass heat from downcomer t...

A major problem in information retrieval is the difficulty to define the information needs of user and on the other hand, when user offers your query there is a vast amount of information to retrieval. Different methods , therefore, have been suggested for query expansion which concerned with reconfiguring of query by increasing efficiency and improving the criterion accuracy in the information...

Object-Relational database systems allow users to define new user-defined types and functions. This presents new optimizer and run-time challenges to the database system on shared-nothing architectures. In this paper, we describe a new strategy we are exploring for the NCR Teradata Multimedia Database System; our focus is directing research for real applications we are seeing. In doing so, we w...

High concentration of dissolved oxygen within microalgae cultures reduces the performance corresponding cultivation system (MCS). The main aim this study is to provide a reliable computational fluid dynamics (CFD)-based methodology enabling simulate two relevant phenomena governing distribution MCS: (i) mass transfer through liquid–air interface and (ii) evolution due photosynthesis including i...

We analyse the detailed structure of a highly-inclined (i & 80◦) disc galaxy which lies within the Hubble Ultra Deep Field (UDF). The unprecedented depth of the UDF data allow disc and extraplanar emission to be reliably traced to surface brightness levels of μV,i,z ∼ 29 − 30 mag arcsec −2 (corresponding to rest-frame equivalents of μg,r,i ∼ 28 − 29 mag arcsec ) in this redshift z = 0.32 system...

The distribution of PM2.5 around a thermal manikin with realistic female body shape in naturally ventilated room has been modelled. health risk (HR) due to inhalation the quantified by integrating pollutants mass flux over boundaries virtual box mannequin’s head (the breathing zone). By same approach HR is evaluated another that surrounds manikins and defines occupied zone. paper focuses on pec...

The electrostatic spray technology can significantly improve the utilization rate of liquid medicine under operation characteristics unmanned aerial vehicles (UAVs) with small load and low volume. To explore settlement law droplets, further amount droplets deposited in target crops, reduce loss missing target, this study adopted method combining numerical simulation high-speed photography to mo...

The study was aimed at evaluating the antioxidant activity of hydroalcoholic solution extracts of Urtica dioica L. (UD), Malva neglecta Wallr. (MN) plants and their mixture. In this study, flower (UDF), root (UDR), seed (UDS) and leaf (UDL) parts of UD and flower (MNF) and leaf (MNL) parts of MN were used. The antioxidant properties of hydroalcoholic extracts and their mixture were evaluated us...
