Title: Engineering Thermal Devices: Simulation experiments

Abstract: Scientists have made sufficient progress in developing devices based electronics, spintronics, and photonics. But the progresses to design and develop the devices that can utilize the flow of phonons are still rare. If flow of heat in solids could be controlled as electric current in semiconductor circuits, very large numbers of innovations could happen in thermal engineering.

We know, the thermal radiation heat-ups the surface exposed by it and the efforts are always made to cool the surface. We have not made sufficient efforts to store this heat for its fruitful use at later. The first-most requirement to utilize the heat is to have a material which allows us to control the flow of heat in desire direction and/or stores the heat for longer time. At nanoscale, to study heat transport thorough a material is not an easy task because of thermal contacts to be made on nanoscale devices, heat baths and temperature sensors are to be connected at nanoscale. Not only this, the carrier of heat – Phonons is not point particle with definite properties but bundles of energy that have no mass or charge which remains unaffected by electromagnetic field. These are main causes why the devices that control the flow of heat in a desire manner are still not available for practical use.

Computer simulation helps in overcoming such problems. Because of some simulation studies, temperature profile, heat flux, thermal conductivity, negative differential thermal resistance, interface thermal resistance, thermal rectification are now known at nanoscale. Our results of heat transport in monoatomic, diatomic chain, linear mass graded, exponential mass graded, mass defected chain, thermal diode, and thermal transistor will be presented during the talk. Such study will help in understanding heat transport mechanism in conducting and non-conducting polymers, RNA/DNA chains, nanowires, nanotubes, etc.. Such study is useful in designing molecular/nano-heat pumps and nano-thermal devices.

Title: Understanding the Relationship between Socioeconomic Status and Cognitive Abilities of Preschoolers

Abstract: Preschool education has been gaining importance in many countries. Previous studies have explored the association between socioeconomic status (SES) and children cognitive abilities and found that parents that were involved in their children’s education would influence their children’s cognitive ability. Parents that are more involved in children’s education do contribute to children’s high levels of cognitive abilities. This study intends to examine the level of cognitive abilities among preschoolers and how it is affected by the parents socioeconomic status (SES). 100 preschoolers aged 6 years old were selected from different socioeconomic background to participate in this study. The samples were represented by 49 boys and 51 girls. The instrument used in this study was the McCharty Scales of Children Abilities (MSCA) test battery that consists of the Verbal test, Perceptual-performance test, Quantitative test and General Cognitive Index (GCI). The results showed that 41% of the preschoolers have a moderate GCI score but they scored highly in the Quantitative section. The study also found that there was a significant difference in the father’s education and the children’s cognitive abilities. However, no significant differences were found on the other three variables including father’s income, father’s occupation and mother’s education. This study concluded that parents with a low level of education does not necessarily have children with low cognitive abilities. There is a need to explore other variables that would impact children’s level of cognitive abilities.

Title: IoT and a small step for social efficiency

Abstract: IoT (Internet of Things), Big Data, and AI (Artificial Intelligence) are the top three buzz words in ICT research areas, and indeed a variety of applications have been realized in advanced parts of the world, both in and among countries. On the other hand, many other parts of the world still suffer from inefficiency issues at least some of which should be improved by technologies. In this talk, instead of summarizing the mainstream of IoT research, I will discuss an issue related to human flows as an example of small steps for social efficiency. Human flow is human behavior of movement and it has been already tackled both in research and commercial perspectives, but still we have inefficient building and event structure where a vast number of people makes inefficient move and congestion as a reality. I introduce a recent research to analyze such human flow, and discuss what we can.
