Abstract Vertical agriculture in urban areas is a new phenomenon where interest needed order to develop. The objective of the research develop tower system vertical farming technique. In this research, could produce 624 plants. This made using PVC pipe with 26 holes per tower. Each set towers equipped an irrigation system, namely water pump drain nutrient pipe. way monitoring works that ESP 32 ...

This research proposes an effective vertical clustering strategy of 3D data in an elliptical helical shape based on 2D geometry. The clustering object is an elliptical cross-sectioned metal pipe which is been bended in to an elliptical helical shape which is used in wearable muscle support designing for welfare industry. The aim of this proposed method is to maximize the vertical clustering (ve...

Using the NASA Goddard Institute for Space Studies (GISS) climate model, it is shown that with proper choice of the gravity wave momentum flux entering the stratosphere and relatively fine vertical layering of at least 500 m in the upper troposphere-lower stratosphere (UTLS), a realistic stratospheric quasi-biennial oscillation (QBO) is modeled with the proper period, amplitude, and structure d...

Abstract Analyses of sedimentology, ichnology and depositional environments Langhian–Tortonian siliciclastic deposits in the southern Tebessa Basin (eastern Algeria) have revealed a tidally dominated deltaic setting with high concentration vertical burrows. From south to north, two are here distinguished Basin: subaerial lower delta plain Oum Ali region trace fossils Ophiomorpha Skolithos linea...

An experimental investigation was conducted to simultaneously measure the instantaneous velocities of large particles and air in two-phase flow using Laser Doppler Velocimeter. Measurements at two Photo-Multiplier voltage settings are used to separate the signals from the small seeding particles that trace the air flow and the suspended solid particle based on the difference of scattered light ...

Heat pipe is a device that transports heat with minimal temperature drop using the latent heat of fluid in a closed container. In vertical type named as thermosyphon (Wickless), capillary action is replaced by the gravitational force, this condenser is placed above evaporator. In this paper, to investigate the effect of inlet air temperature and the air mass flow rate was studied. The temperatu...

-Deterioration in heat transfer at supercritical water cooling in a vertical pipe is numerically analyzed. The calculation is based on a parabolic solver for steady-state equations in r-z two dimensions, a Ice model for turbulence and a steam table library for physical properties of supercritical water. Calculation results agree with the experimental data of Yamagata et al. It is found that hea...

Gas-lift pumps are devices for lifting liquid phase incorporating the gas phase to be injected in the bottom of liquid column. They are widely used in various industrial applications such as oil extracting in petroleum industries. Gas-liquid flow being the main part of the flow through these systems, flowing in vertical pipes of gas-lift pumps has different regimes namely bubbly, slug, chur...

The data reported in this article presents actual installation costs and performance data for a selection of residential Ground Source Heat Pump (GSHP) systems in Melbourne, Australia. The installation cost data includes five main cost components: ground loop installation, head pipe installation, heat pump, mechanical room installation, and fittings. The performance data presented here includes...
