Rocket Engine Combustion Instability Naveen Penmetsa University of Colorado, Boulder, CO, 80309 C ombustion instability has long been an area of research in the design of both aircraft and rocket engines. Specifically in terms of rocket engines, combustion instabilities occur in every type of engine including solid rocket motors, cryogenic engines, hyperbolic engines, and hydrocarbon engines. Although combustion oscillations tends to exist in almost every engine, the goal is to minimize these variations

Nathanael Betz Narrative 1 Knutson 18 December 17 Deep Ocean Surfing At 5:30 a.m. My alarm clock buzzed. It was Wednesday. I thought to myself, school doesn't start for another two and a half hours. I suddenly remembered it's one of the most exciting days that I will experience. Both my parents were sleeping. I turned off my alarm and got out of my warm bed. Immediately I put on swimming shorts with no shirt, to top it off a flat brim hat sitting backwards on my head. I walked into the hallway

The waves form and break in front of me, the sound of them crashing lingers in my ears . Sitting here at the beach, I feel as if the world was still and I was the only one who existed. My toes dig into the warm, golden sand and the pleasure sweeps over me. The slight breeze is twisting my hair into knots but I don’t care. Without a breeze, the beach wouldn’t be the beach. All I hear is the roaring waves crashing in front of me and the smell of salt and sand in the air. My feet hit the icy water and

is the type of thing that just makes one feel invincible once accomplished. When I was nine years old, I was given the opportunity to surf for the first time in Maui, Hawaii where I overcame my fear of trying new things. I woke up to the sound of waves crashing onto the beach and a seagull’s “Caw! Caw!” For some reason, being on vacation makes me famished in the morning, so I got up and walked into the kitchen where my dad had already made me some scrumptious scrambled eggs. I devoured them and then

Abstract The health and economic impact of food spoilage to both consumers and producers are enormous, it has a detrimental effect on the consumer's health and negatively impacts the bottom line of the producers. In the past monitoring of food quality are done using a sensor which observes changes in temperature, releases of gases which are not effective and every year million health cases result from food spoilage. This paper introduces an intelligent monitoring system that uses NFC based sensor

It was a sunny day meaning only the main street lights had to be on during the day. Sarah Gamble was outside drawing messages in the mud when her mom called her inside. “Wipe your feet and help me clean up for our guests. They’ll be here in about fifteen minutes.” Sarah had heard about her cousin Travis, but had only imagined the details of his personality. She dreamed of a strawberry blonde with cute freckles and a goofy smile. A boy with an imaginative brain and an adventurous spirit just like

• Undesirable harmonics are absent. • Reactive power compensation is possible. Disadvantages: • Resonance with line impedance occurs. • Tuning frequency is less accurate and requires a lot of calculations. • It cannot be used when harmonic components vary randomly. • Heavy and bulky. 3.1.2 Active Filters: It inject equal and opposite harmonics onto the power system to cancel those generated by other equipment. Remarkable advances in the field of power electronics had sparked interest in APF for harmonic

Hypothesis: In the study it was hypothesized that as the nicotine dependence progresses it would lead to low positivity in the mood, high negativity in the mood, and higher mood variability. The study also observed whether nicotine dependence in a person changes after increasing the frequency of the person smoking during the course of the study. Methods: a. Participants In the study, the participants who were recruited were from the SECASP project. The study was a longitudinal study based on examining

The Same The birds awoke me again this morning. Scraping and tapping at my window; almost begging me to get out there and play with them. They are the most beautiful creatures in the world, you know? The way they have the ability to soar anywhere they desire. To explore the far edges of the horizon, flying over trees and escaping from the world on the ground. The day began to unravel, as any other before it. The weather fine, the children giggling and playing with one another in the yards. I

splashing in the water riding the waves, riding our boogie boards. Oh yes today was going to be fun! As I put on my swim suit I smelt the lingering smell of the oceans salty water from the previous time we had gone to the beach. It reminded me of how much fun I had, had and made me even more exited. The whole time we were in the car driving to the beach I couldn’t help but remember how much I loved the ocean, I loved the salty water, the enormous waves, I loved riding the waves with my board or just body
