The airflow structure of enclosure directly affects the spread COVID-19 and is also closely related to indoor air quality, thermal comfort personnel, building energy consumption. Although a large number studies on field have been conducted under mixing displacement ventilation with single inlet in rectangular rooms. However, best authors knowledge, only limited dealt structures multi-slot oppos...

A numerical investigation was carried out in order to predict the effects of symmetric heating on irregular acoustic streaming in air-filled shallow enclosures. The fluid motion is driven by periodic vibration of the enclosure left wall. The vertical walls of the enclosure are adiabatic while the horizontal walls are heated symmetrically. A control-volume method based, explicit time-marching Fl...

A convenient mathematical formulation is given for the absolute lowfrequency response of an electrodynamic direct radiator loudspeaker mounted in a vented or unvented enclosure. The combined effects of speaker Q (ratio of reactance to resistance), enclosure size, and enclosure tuning are shown to control the convergence of the response curve towards ts asymptotic value. Mathematical criteria ar...

Enclosure and Acacia shade availability to plants are basic variable in arid and semi-arid rangelands. the aim of this study was investigation the impact of patch enclosure and Acacia shade using four treatments which are Inside Enclosure Under Acacia shade (IEUA), Inside Enclosure Without Acacia shade (IEWA), Outside Enclosure Under Acacia shade (OEUA) and Outside Enclosure W...

BACKGROUND Dairy goats are commonly housed at a space allowance of 0.7-0.8 m²/goat in commercial Norwegian goat herds, which is very low compared to regulations and recommendations in other European countries. One easy and cheap way to increase space allowance is to allow the animals' access to outdoor area. The aim of this study was to investigate the effect of access to an outside enclosure a...

Soil  erosion  as a  one  of  the  biggest  environmental  problems  worldwide, is threatening  both ecosystem health and  food security. This case study conducted in Khamsan paired watersheds aimed to compare runoff volume and sediment yields from 51 natural rainfall events on 18 USLE’s standard plots, where they had installed on the different conditions in the term of enclosure and aspect. Fa...

Consider linear systems involving affine-linear dependencies on interval parameters. Presented is a free C-XSC software implementing a generalized parametric fixed-point iteration method for verified enclosure of the parametric solution set. Some specific features of the corresponding algorithm concerning sharp enclosure of the contracting matrix and inner approximation of the solution enclosur...
