At SUNY Buffalo, I took classes on sustainable energy systems and climate change, and that’s where I first discovered that one of the main sources for environmental emissions is the electricity sector/power grid. I became really interested in learning about that aspect of electricity production,” she explains. You'll find that virtually all of these transmitters use ASK/OOK to transmit. Additionally, many of the receivers support interoperability by using the same OOK signaling. This can be confirmed by testing several garage door openers, going over the FCC documents for several transmitters, and noting the supported models in various garage door openers. Encoders The first attempt at reduction is pretty obvious and is to remove the retransmission. Instead of transmitting the signal 5 times each time, only transmit it once. It's transmitted multiple times to help the receiver detect it in case of interference, but assuming there's no interference or issues receiving, this reduces the time by 5! Arbabzadeh’s interest in contributing to the SESAME tool spans beyond professional motivation: “Personally, I want to make an impact. I was very interested in coming to MITEI to work on this tool because when it becomes available, it will really make a difference in various sectors and will be so useful for stakeholders working across the energy space.” Both Goteti and Ghosh also value the proximity to leading faculty, within MITEI and across MIT. “Getting inside access to faculty is a big deal for me, coming from India,” says Goteti.

In addition to supporting each other as they bring their various areas of expertise to bear on their work at MITEI, the team members say they have found support from MITEI and from the MIT postdoc community as a whole. Galland's phrase has been variously translated from the French into English as "Sesame, open", [2] "Open, sesame" and "Open, O sesame".

The team is also working to incorporate other environmental impact categories in the model—beyond just greenhouse gas emissions, which is the tool’s current focus. They are hoping to include factors such as water impacts, air pollutants, and land use.

In contrast to the United States, Norway’s energy sector is already clean because a huge amount of its power generation comes from hydro, with some support from wind and thermal,” she says. Norwegian exports to continental Europe can enable displacement of coal with natural gas and reduce greenhouse gas emissions. It is interesting for me to develop a tool that can bring together all of these pieces from different sectors—power, transportation, et cetera—and that will allow policymakers and energy modelers to use the tool to do a system analysis for themselves,” she says. I ghetto-rigged some wire to the test pads and superglued the ends to always connect properly to the GoodFET, but you can also use the GIMME from Michael Ossmann for a more convenient connector. Open sesame has been classified by Stith Thompson as motif element D1552.2, "Mountain opens to magic formula". [9] See also [ edit ] We went from 1771 seconds down to 8 seconds. Even our most efficient implementation with the other reductions but without De Bruijn was at 177 seconds, more than 20 times longer. Awesome!

I feel fortunate to have a peek into this very exclusive world. These kinds of opportunities—being able to engage with the world’s leading researchers, CEOs, et cetera—were just not available to me at my previous institutions,” says Ghosh. “The founder of Zipcar sits right across from my cubicle! There is a Nobel Prize–winning lab on the floor below ours.” There are a number of resources and tools, many of which I've learned from and that you can learn more on this and similar topic too.

The immediate assumption is that these fixed pin garages and gates span a wide range of frequencies. For example, Wikipedia suggests these wireless devices span 300MHz - 400MHz, requiring us to send the same signal to 100 additional frequencies. However, after pulling the FCC docs of all of the fixed transmitters I could find, we see only a handful of frequencies are ever used, primarily 300MHz, 310MHz, 315MHz, 318MHz and 390MHz. Meet the interdisciplinary team of postdocs who came to MIT to work on MITEI’s novel energy assessment tool—the Sustainable Energy System Analysis Modeling Environment (SESAME). Left to right: Emre Gençer, a MITEI research scientist, is working with postdocs Naga Srujana Goteti, Maryam Arbabzadeh, and Tapajyoti Ghosh to expand the tool. Credit: Kelley TraversToday, we are facing a dual challenge: satisfying growing energy demand while reducing emissions,” says Emre Gençer, a research scientist at MITEI and leader of the SESAME project. “The composition and operation of energy systems determine our ability to meet this challenge. We developed SESAME to study all energy sectors at the pathway and system levels.”

Each member of the trio will present results from their portions of the SESAME tool expansion at various conferences. The team has also contributed to a series of journal articles about the tool, which they anticipate will be published over the coming year. Arbabzadeh is focused on using her experience to solve environmental challenges for the benefit of our planet and its future inhabitants. “During my master’s degree work, I learned about the negative environmental impacts of electricity production and wondered: ‘How can we improve this? I have the skills and knowledge, but how can I do more?’” adds Arbabzadeh. “Trying to solve these challenges is exciting for me. I think the energy sector is very important in terms of climate change, and the decarbonization of power production is an area where we can truly make a positive impact for future generations.” Sustainable engineering focuses on trying to reduce negative environmental impacts that are caused by engineering processes not considering the external impacts of their activities,” he says. “I was interested in figuring out how we can make our engineering processes take environmental impacts into account during the design process while also helping industry make profits.”

Ghosh’s role at MITEI is to literally “open SESAME”—he is working to convert the tool from a MATLAB application, which is a proprietary programming language developed by MathWorks, to an open-source web application, which will make SESAME available for all to use. This is a Herculean effort; the SESAME platform was designed with a modular structure to allow the analysis of a very large number of conventional and novel pathways—more than 1,000 energy pathways are embedded in the framework, capturing about 90% of energy-related emissions data. SESAME’s framework provides multiple functionalities for various energy stakeholders in a single tool. For example, those working in industry or policy can compare technology options, perform technology and system scenario analyses, or explore the impacts of market and policy dynamics; or energy experts can see comprehensive cross-technology comparisons. Ghosh needs to translate all of this into Python coding language for the open-source version of the tool.
