Fabrication of 2 way cross flow cooling tower for high pressure boilerEcway Technologies
This document describes the fabrication of a 2-way cross flow cooling tower for a high pressure boiler. It discusses cooling towers which use evaporation or air to remove process heat and cool working fluids. The objective is to remove heat from industrial sources like machinery using large cooling towers, as seen in power plants. It explains that a cooling tower allows dissipating heat into the atmosphere instead of discharging hot water into local bodies of water, which can harm ecosystems. It then provides details on the working principle of a cross flow design where air and water flow perpendicularly through a fill material for efficient heat transfer.
Design and fabrication of pneumatic design and fabrication of pneumatic Ecway Technologies
This document describes a project to design and fabricate a pneumatic lifting table. It discusses how pneumatic systems use compressed air to transfer energy and do work by applying and releasing fluid pressure. The lifting table uses pneumatic power to safely raise and position heavy loads for ergonomic access. It can be powered by compressed air or alternative power sources.
This document describes a project to develop an accident avoidance system for ramming machines. The system uses an IR transmitter and receiver to detect if an object gets too close to the machine, which will then trip a relay to stop the machine and sound an alarm. A vibration sensor and earth fault detector are also used to monitor vibrations and faults that could indicate issues. The system aims to make the machines safer for operators through quick response times and simple construction, while reducing accidents. Some benefits are increased safety and automatic accident prevention, while the main disadvantage is additional costs. Potential applications include heavy cutting machines, ramming machines, and foundries.

This portfolio was created by Andriana Andrulyte to showcase her work and apply for undergraduate studies in fashion design. It includes 15 sketches and descriptions of original outfits and clothing designs. The designs draw inspiration from nature, magazines, and specific brands. They showcase Andriana's creativity in color, pattern, silhouettes and details for both casual and party wear. The common themes are adding color, sparkle and elegance to clothing while experimenting with different fabrics, textures and styles.
