Recent, rapid advancement in visual question answering architecture: a review
Understanding visual question answering is going to be crucial for numerous
human activities. However, it presents major challenges at the heart of the
artificial intelligence endeavor. This paper presents an update on the rapid
advancements in visual question answering using images that have occurred in
the last couple of years. Tremendous growth in research on improving visual
question answering system architecture has been published recently, showing the
importance of multimodal architectures. Several points on the benefits of
visual question answering are mentioned in the review paper by Manmadhan et al.
(2020), on which the present article builds, including subsequent updates in
the field.Comment: 11 page
Moore’s Law and Space Exploration: New Insights and Next Steps
Understanding how technology changes over time is important for industry, science, and government policy. Empirical examination of the capability of technologies across various domains reveals that they often progress at an exponential rate. In addition, mathematical models of technological development have proven successful in deepening our understanding. One area that has not been shown to demonstrate exponential trends, until recently, has been space travel.
This paper will present plots illustrating trends in the mean lifespan of satellites whose lifespans ended in a given year. Our study identifies both Wright’s law and Moore’s law regressions. For the Moore’s law regression, we found a doubling time of approximately 15 years. For Wright’s law we can see an approximate doubling of lifespan with every doubling of accumulated launches. We conclude by presenting a conundrum generated by the use of Moore’s law that is the subject of ongoing research
Travel to extraterrestrial bodies over time: some exploratory analyses of mission data
This paper discusses data pertaining to space missions to astronomical bodies beyond earth. The analyses provide summarizing facts and graphs obtained by mining data about (1) missions launched by all countries that go to the moon and planets, and (2) Earth satellites obtained from a Union of Concerned Scientists (UCS) dataset and lists of publically available satellite data
An Unusual Complex Odontoma
Odontoma, complex type is an agglomerate of all the dental tissues that are characterized by normal histodifferentiation but abnormal morphodifferentiation producing little or no resemblance to normal tooth form. They are usually asymptomatic but often associated with eruption disturbances. An interesting case of unusually large complex odontoma that was associated with pain and an impacted as well as missing molar is reported
