Investigate waste management issue in Mexico Restaurant

Reliable data on waste management and controlling waste will be illuminated in an effective way to suggest better waste management practices in the hospitality industry in New Zealand. This research suggests effective steps to regain and minimize the waste produced in Mexico restaurant, which is located in Victoria Street, Hamilton. To obtain the data, interviews and observation were the preliminary methods used in this research to clearly understand the main cause of the problem by the organisation in terms of waste. This research has covered waste management issues faced in SMEs and steps to control food waste in restaurants. All the collected data are compared and analysed under a statistical result and these results are discussed on the basis of the current waste management practices of the business. The key findings recommend a possible method to control waste and implementing new software to monitor the waste. Further research will carry over under the same stream by influencing engineering methods and machines, which will be a positive deliverable for a sustainable environment and society

Modeling, simulation and implementation of low power photovoltaic energy conversion system

Remote areas in India are still not connected to the power grid. But they have mobile network connectivity. The people face problems in charging their cell phones. They are forced to travel a long distances to get access to electrical outlets. This project focuses on providing a Photovoltaic System which could charge a cell phone battery. The developed system provides a solution to this problem. The system comprises of PV array, Maximum Power Point Tracker, Buck Converter and Charging Circuit. The system is modeled and simulated in Matlab-Simulink Environment. Hardware for the system is also implemented. We find proper synchronism between the results

Smart Energy Home Management Using Hybrid system

Energy balance is one of the main criteria to operate the grid in stable condition. If there is any energy imbalance occurs due to increase in demand then the grid will not operate in stable condition. Increase demand is one of the major issues facing by grid. To address this problems many countries promoting the renewable energy generation this will support the grid to avoid energy imbalance problem. Prosumerplay a key role in this situation, where they can utilize the generated energy and remaining surplus power can integrate it to the grid. While utilising the renewable power generate it should be controlled and monitored effectively so that we can reduce the tariff cost. Solar panels installed in house need to  bemonitored continuously to improve the performance of battery. In this paper, the power line communication (PLC) compliant with Home Plug is implementing to check energy consumption. The system design is composed of three components: Driver circuit, ac supply, and smart device application. This system will switch over from solar energy consumption to AC supply according to the load requirement. This scheme will maintain the performance of a PV system and contribute to enhancing home energy  management system. The system design was stimulated with Matlaband verified with the hardwareresults

Corrosion Behavior of Steel in Deficient Grout with Enhanced Sulfate Ion Concentrations

Recent corrosion failures of tendons in Florida post-tensioned (PT) bridges utilizing low bleed specified grout products have shown the need for better understanding of the mechanisms that cause corrosion and to determine the extent of the problem in PT tendons with similar materials. Those deficient grouts in the tendons showed low chloride content below commonly assumed threshold limits for corrosion initiation, but they showed higher concentrations of sulfate ions, high pore water pH and higher moisture content. The role of enhanced sulfate ion concentrations in the development of steel corrosion in deficient grout has not been elucidated, but the role of sulfate ions in deficient grout with high moisture content may be comparable to the role of sulfate ions in alkaline solution. The objectives of the research were to verify the role of sulfates but also to quantify sulfate content and introduce possible sulfate limits for corrosion development in various grout conditions. To examine the cause of corrosion failure, large-scale mockup tendons of about 15 feet long were cast using expired grout materials, an excess of 15% water mix water, and enhanced chloride and sulfate concentrations to create deficiencies and corrosion conditions in the grout environment. The tendons were cast at a 30-degree incline to produce segregated grout on the upper elevation. Steel probes were embedded in the tendons on varying heights and corrosion measurements were carried on these probes. The role of pH (12.
