OVERVIEW OF COGENERATION OPPORTUNITIES IN NEPALESE SUGAR SECTOR eecfncci
This document provides an overview of cogeneration opportunities in the Nepalese sugar sector. It discusses how cogeneration works by using fuel to generate both steam for industrial processes and electricity. The sugar sector in Nepal is described, including annual sugarcane production and bagasse production. Current practices and configurations in sugar plants are outlined. The document proposes upgrading to higher pressure boilers and turbines to increase power generation potential. Estimates suggest upgrading several plants could generate over 50 MW of surplus power for the grid.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
