A Solar Panels Automatic Tracking System Based on PLC
Abstract:
This project Aiming at low density of solar energy, intermittent of solar ray, changing light intensity and direction with time, the project studies maximum power point of photovoltaic module based on DELTA PLC. The system designed the hardware and software, and the hardware included PLC I/O configuration, the signal processing unit, the comparison circuit of photosensitive resistance for detecting ray strength, photovoltaic modules and switch power supply; and the softwar ....etc

ABSTRACT

Objective:
• To study the effect of fibres on the strength and behaviour of ultra high performance concrete (UHPC)wall panels under one way and two way in plane action.


Methodology:
The UHPC mix already developed (taken from literature) studied in detail with regard to its fresh and hardened properties and durability. Wall panels of size 750x750x35 mm are to be cast with different aspect ratio and volume fraction of fibres for testing under one way in plane action and two way in plane action. The speci ....etc

INTRODUCTION-CONCRETE
 The word concrete comes from the Latin word concretus (meaning compact or condensed), the past participle of concresco, from com- (together) and cresco (to grow).
 Concrete is a construction material composed of cement ,coarse aggregate , plus a fine aggregate such as sand, water, and chemical admixtures.
ORIGIN OF HPC AND UHPC
 Environmental aspects
 The necessity to decrease the amount of CO2 in atmosphere.
 Replacement o ....etc

It is often desirable for structural steel members to pass through a fire wall
or common wall rather than being curtailed on each side of the wall. In such cases, the penetrating member will often be fire protected for a certain length on each side of the wall so as to minimise the possibility of fire spread through heat conduction and excessive temperature rise of the member on the unexposed side of the wall. This latter aspect is necessary to ensure that lateral restraint will continue to be provided to the top of the wall by the member on t ....etc
