We Should Have Already Had This: The Lithium-Ion Battery With Built-In Fire Suppression

  On October 22, 2020, yesterday, Dexter Johnson posted The Lithium-Ion Battery With Built-In Fire Suppression . Within this topic, Dexter Johnson regards a Stanford University research team and the SLAC National Accelerator Laboratory (its former name was the Stanford Linear Accelerator Center [1] ). Johnson stated: Now [Yi] Cui and his research team, in collaboration with SLAC National Accelerator Laboratory, have offered some exciting new capabilities for lithium-ion batteries based around a new polymer material they are using in the current collectors for them. The researchers claim this new design to current collectors increases efficiency in Li-ion batteries and reduces the risk of fires associated with these batteries. [2]   Johnson was saying this: fires are a current Li-ion battery threat that has been realized, but a new design can secure client use-case safety, and this required this battery redesigned. As this technology approaches marketplace entry points, this shall c

COVID-19


On 17 April, 2020, 5:00 AM Chicago, IL time, Greg Stewart, Klaske van Heusden, and Guy A. Dumont released the IEEE SPECTRUM article How Control Theory Can Help Us Control COVID-19 (link). Stewart, et. al. wrote, “As we write these words, several billion people, the majority of the world’s population, are confined to their homes or subject to physical-distancing policies in an attempt to contain on of the worst pandemics of modern times” (Stewart, Heusden, Dumont, 17 Apr, 2020). This is a reflection against the COVID-19 pandemic’s recorded measures.

The Reproduction Number of COVID-19


Against other recent disease outbreaks, Stewart, et. al. wrote that the COVID-19 pandemic is unique: the reproduction number, or Ro (“R naught”), that is, the infection rate per infected person during infection.

The Cost of Easing Social-Distancing Restrictions

About easing social-distancing standardization, Stewart, et. al. wrote a commonly cited proposition is binary in scope because some blocks would be removed only when intensive care cases do not extend beyond a certain number.

For a Holistic Model: Simulating a Highly Infectious Disease
Against non-binary nonpharmaceutical interventions, Stewart, et. al simulated recovery strategy policies to contend against a commonly used infectious-disease model. As a result, the most dangerous time an intensive care patient can experience, wrote Stewart et. al., was inclusively between the first and third months of virtually any deadly and highly contagious illness due to patients’ need of critical care relatively far outnumbered all of the available beds in the intensive care unit. Due to easing social-distancing restrictions, the second surge, said Stewart, et. al. of this is inclusively between the third and fifth months, so the disease effectively doubles its dangerousness.

Next, Stewart, et. al. displayed: although the binary, on-off, approach, began relatively dangerous inclusively during the first two months, its patient population effectively halved inclusively from the third month to the seventh month. Also, the patients’ critical care need peaked every month, but valleyed every two months. Plus, the R0 values are inversely proportional to the binary on-off approach’s number of patients or beds, so this means intensive care had been historically capable of successfully mitigating highly infectious diseases.

According to Stewart, et. al. their third experiment had a different goal: ninety percent occupancy in hospital intensive care units, and they designed a control systems theory-based policy based on simple feedback. In summary of Stewart, et. al., the Ro being high warrants many restrictions implemented. In contrast, later conditions began improvement, and other social services are allowed. This process enabled the maximum rate of recovery. During the first month that the pandemic model began its simulation, the patients needing critical care decreased against the threshold, and this model prevented any further threshold exceeder months, inclusively, from the second month to the seventh. Also, the R0 number is inversely proportional to the patients who needed intensive care because of uncertain patients since many reports of a highly infectious disease were self-reported. Even noncompliance, said Stewart, et. al., is not a great enough deterrent to withdraw the feedback policy because the variance is, in summary, logarithmic, so eventually little change in control effectiveness transpired. This is a Web-based tool, and the biggest challenge, said Stewart, et. al. would be onboarding nonspecialists because the epidemiological model has various components, and these components work with the feedback policy selections and different model noncompliances.

Slaves to Christ and Feedback
In the Apostle Paul’s (INT) Epistle to the Ephesians, the Apostle Paul recommended slavery. The Apostle Paul said (link), “not with eye-service as men-pleasers, but as servants of Christ, doing the will - of God from [the] heart” (6:6). Given that many of the Bishop, Paul’s, epistles include feedback such as to Timothy, and also to Timothy and Silvanus, together (1 Thess 1:1), this indicates that Paul had countered noncompliance with a substantial amount of feedback, and this is evident because Paul authored most of the New Testament. Since Christianity is one of the world’s most popular religions (link), the adoption of a feedback model is crucially dependent on limiting noncompliance. For onboarding nonspecialists of the infectious disease model, then, the goal ought to be a mentor-catechism program. This is better than another Master-slave relationship because the Christianity controls are already mostly in place, worldwide.

In response to the Institute of Industrial Science, the University of Tokyo’s Circular Reasoning: Spiral Circuits for More Efficient AI

Circular Reasoning On June 14, 2020, the IIS (Institute of Industrial Science) at the UTokyo (University of Tokyo) wrote  Circular Reasoning: Spiraling Circuits for More Efficient AI ; but a Press Release from this institute is giving a synopsis on this topic. On this press release, the IIS wrote, “Researchers from the Institute of Industrial Science at the University of Tokyo designed and built specialized computer hardware consisting of stacks of memory modules arranged in a 3D-spiral for artificial intelligence (AI) applications” (IIS, June 14, 2020). The IIS continued on, saying this research is allowing a singular way work can be done regarding the next generation energy efficient AI devices (Here is a current generation, but energy efficient, AI device, Android Pie: link ) shall be implemented into production.             The Fundamentals of Machine Learning                On this press release, the IIS is explaining the fundamentals of ML (Machine Learning).

IS the Future of AI “Women?”

Interdisciplinary Campus Culture On April 14, 2020, Katy Rank Lev wrote the Carnegie Mellon University’s (CMU) news article The Future of AI is Female . Since artificial intelligence’s (AI) initial measurement, wrote Lev, CMU built AI. Lev wrote that each of the colleges CMU is representing contribute to make AI a new field, describing this AI as a frontier, humanity can democratize: from healthcare, the eventual goal area is education. In a rush, Lev cut the conversation short, and Lev mentioned CMU’s interdisciplinary campus culture as the source of the effective AI women, but this is despite women historically not represented as scientists, technologists, and engineers, and math (STEM), worldwide. But CMU is spotlighting undergraduate students and highly honored faculty members, and Lev is including these women because she agrees with the Women in Tech movement as far as the East is from the West: CMU is the best Computer Science University with AI, and this is IT at this point in

Drone Uses AI and 11,500 Crashes to Learn How to Fly

Learning to Fly by Crashing On 10 May, 2017, Evan Ackerman wrote the IEEE (Institute for Electricians and Electrical Engineers) SPECTRUM article Drone Uses AI and 11,500 Crashes to Learn How to Fly. In Ackerman’s article, Ackerman used a block quote by Carnegie Mellon University roboticists Dhiraj Gandhi, Lerrel Pinto; and Abhinav Gupta, the writers of a paper, “Learning to Fly by Crashing” (Gandhi, et. al., 27 Apr 2017). From Ackerman’s block quote from Gandhi, et. al., “[T]he gap between simulation and real world remains large especially for perception problems” (Gandhi, et. al.). Ackerman contrasted known motion from unconfirmed motion without identifying the pre-existing condition called Schrödinger’s cat in the case that the crashes shall eventually happen without outside help: a continuing crash failure, and in security terms this is interned as a false positive because this helps Schrödinger’s cat stay alive or rest buried in the soil. In this case, this drone detects these t
