North -East India is one of the largest producers of pineapples in the country, and there are many small fruit-processing units across the region that process pineapples during the harvest season. These units, being labor-intensive, are a significant source of employment for the local population. Pineapple processing activities, mainly, starts with the manual peeling task that is quite repetitive, time-taking and laborious. The well-being and productivity of the workers and highly compromised due to use of old traditional tools and techniques. In spite of the various peeling related issues, the processing units adhere to the traditional peeling methods as they don¿t find any solution appropriate to their context of use. The thesis looks into existing work process related to pineapple processing and associated physical and occupational issues including risk factors influencing productivity. The issues are then addressed through strategic design intervention, developing work methods, tools, and equipment for safe, effective, fast peeling of pineapples.

Power extension of grid to isolated regions is associated with technical and economic issues. It has encouraged exploration and exploitation of decentralized power generation using renewable energy sources. Renewable energy sources-based power generation involves uncertain availability of power source round the clock. This problem has been overcome to certain extent by installing appropriate integrated energy storage unit. This Book presents technical review of hybrid wind and photovoltaic generation in standalone mode. Associated components like converters, storage unit, controllers, and optimization techniques affect overall generation. Wind and photovoltaic energy are readily available, omnipresent, and expected to contribute major future energy market. It can serve to overcome global warming problem arising due to emissions in fossil fuel based thermal generation units. This book includes the study of progressive development of standalone renewable generation units based on wind and PV microgrids.
