Hybrid Cycle with the Combination of Flywheel and Gear System
The mean of my hybrid cycle is that the flywheel connected with the back wheel with the help of chain mechanism and also the gear system connected with it. The main function of flywheel is to store the waste energy which arises due to break. Like heat energy, sound energy. And the stored energy utilized by the help of gears as we required speed during riding.

IRJET- Hyperloop Transportation System
This document provides an overview of the Hyperloop transportation system. Some key points:
- Hyperloop uses pods or capsules that travel inside low pressure tubes using magnetic levitation. This allows the pods to reach speeds over 1200 km/h.
- The tubes have air compressors that maintain low pressure, reducing air resistance and allowing high speeds. Linear induction motors along the tubes propel the pods.
- Hyperloop has the potential to be faster, cheaper to build and more energy efficient than other high-speed rail and transportation systems. It could transport people and goods over long distances in under an hour.
- Two versions are proposed - a passenger only pod, and a passenger plus vehicle pod.
Lehigh Hyperloop Preliminary Design Briefing 2017 (2)
The Lehigh Hyperloop team aims to design and build a prototype pod that can travel at up to 180 m/s (400 mph). The team is made up of undergraduate students led by Emma Isaacs, Tech Tana, and Gencer Ates. The estimated 487 kg pod uses magnetic levitation, cold air propulsion, eddy current braking, and other systems. It is designed with various safety features to ensure controlled braking and stopping in case of emergencies. The team performs its work out of the Wilbur Powerhouse facility on Lehigh's Mountaintop Campus.
Abstract DEP
This document summarizes a research project on designing and testing a distributed electric propulsion system for aircraft. Distributed electric propulsion involves placing multiple small engines around the aircraft's fuselage and wings to improve efficiency. The project aims to design and test a scaled model aircraft powered by 10-12 small electric engines distributed along its wingspan. Testing will analyze lift characteristics at varying payloads. Distributed electric propulsion could make air travel more efficient, economical, and environmentally friendly by increasing lift and reducing emissions compared to traditional jet engines.

- SJTU-EX has two pseudo-anthropomorphic legs, with each leg containing four active joints (hip flexion/extension, hip abduction/adduction, ankle flexion/extension, ankle abduction/adduction) and two passive joints (diamond mechanism joints replacing knee).
- Springs are applied to both active and passive joints to store energy during swinging and help support weight during stance phase.
- The parallel diamond mechanism between hip and ankle increases load capacity over series architectures and provides a large workspace.

High Performance Computing for Accelerating Sustainable Transportation Innova...
Today, making gains in vehicle efficiencies is becoming extremely difficult as one needs to consider the complex interaction between the engine, battery, power electronics, materials, controls, aerodynamics, etc. and find optimal solutions that provide safe and affordable vehicles with small carbon footprint. It is thus important to codify and automate the knowledge and intuition we have collectively acquired so far and use our precious human resource for the creative solutions that build upon that. Computational science is prime to tackle this challenge as it is the only tool within our reach to get an handle on the exponential increase in the vehicle calibration space that is needed to find optimal designs. Computational Science, the field of using computers and numerical algorithms/methods to enable scientific discoveries and technology innovations, is a rapidly growing field that has a huge potential to revolutionize the way science and engineering has been performed for centuries. For this reason, it is often called the third pillar of modern science complimenting observations and theory. Since the advent of transistor (not so long ago) and rapid innovations in the electronics industry, the computing power has increased exponentially with extreme affordability (the GPU on Ipad3 has 32,000 X operations compared to mainframe from the 60s). The modern supercomputers utilize large number of such compute cores (100s to millions) to provide compute capabilities that we did not even dream off few decades back. It is the challenge, great opportunity, and promise in front of us to translate the knowledge we have acquired through observations and adapt the existing theoretical frameworks to generate clear set of instructions that we can compute at scale to simulate real-world applications. The integration of observations (through advanced characterization), theory, computations, and now data would be the driving force of science and technology for sustainable transportation but also broader field of management of energy and water resources while minimizing environmental impact. In this talk, I will give specific examples of computational effort related to transportation (engines, battery performance and safety, pyrolysis of biomass for transportation fuels, thermal management in power electronics, etc.) and lay down a roadmap as to how we can utilize HPC to accelerate the design of highly efficient and cost-effective vehicles that meet the regulatory, safety, and consumer demands going forward.

OSU was the first public entity in Oregon to receive a Certificate of Authorization (COA) for unmanned aircraft systems (UAS) flights in 2012. The document summarizes that OSU now has 25 active COAs across 5 states and has conducted UAS flights internationally for purposes such as remote sensing in agriculture, earth and oceanic sciences, engineering, forestry, fish and wildlife, and search and rescue applications. OSU is dedicated to using UAS for these types of remote sensing projects.

This document discusses using small unmanned aircraft to detect Colorado potato beetle damage. A working group from USDA-ARS and Oregon State University is researching how to use multi-spectral and hyper-spectral imagery from unmanned aircraft to identify and locate plant stress. The group has found that small unmanned aircraft can detect a nitrogen deficiency in potatoes and capture images showing a Colorado potato beetle outbreak on potatoes within a day. Further independent study and data validation is needed but growers have expressed interest in this detection technology.

UAS and distributed temperature sensing technologies allow atmospheric scientists to observe previously unseen processes. UAS provide high resolution temperature data over large areas at lower costs than traditional tall towers. A study used a UAS equipped with distributed temperature sensing to observe the morning transition period, finding that the sharpness of the temperature gradient decreased by around 4 minutes or 250 meters as vertical mixing weakened the gradient. These new observation methods enable capturing a broader range of spatial and temporal scales than ever before and will lead to new discoveries as atmospheric science moves to more representative locations.

UAVs have potential for cost-effective data collection for civil engineering applications. Researchers at Oregon State University are using UAVs to inspect bridges and wireless towers, map slopes for stability analysis, and conduct surveys. Students are gaining experience with UAV photogrammetry, laser scanning, and GPS techniques. Research aims to evaluate UAV accuracy, optimize data collection and processing, and explore applications such as transmission line inspection and post-disaster mapping.

The document summarizes the work of the Linus Pauling Institute at Oregon State University over the past 13 years. It discusses the Institute's focus on determining the roles of micronutrients, antioxidants, and other dietary factors in promoting optimal health and preventing disease. Key areas of research include cancer prevention, cardiovascular health, aging, and the protective effects of certain foods/compounds against oxidative stress and inflammation. The Institute has grown from half a researcher in 1996 to 12 full researchers and 4 research assistants currently. The work described emphasizes the important influence of diet and lifestyle on gene expression and chronic disease risk, beyond just genetic factors.
