Parallelization of microfluidic droplet generators is one of the major challenges that droplet microfluidics has to overcome to contribute significantly towards the sustainable manufacturing of advanced materials such as nanoparticles, quantum dots, active pharmaceuticals, etc. A massive parallelization system needs to maintain consistency and uniformity across all droplet makers. To achieve ...

Time-Domain Model of the Inner Ear to Study Nonlinear Responses

The ear doesn’t solely listen but it also speaks. Sounds formed in the inner ear which are measurable in the outer ear are called Otoacoustic emissions (OAEs). Some claim these are produced by the outer hair cells (OHCs), the amplifiers in the inner ear. Our hypothesis is that the OHCs only amplify distortion products (DPs) but do not produce them.

Multiphysics Analysis and Optimization of Mechatronic Device Applications for Switching Devices

O. Cracium[1]
[1]ABB, Ladenburg, Germany

Medium- and high-voltage circuit breakers and reclosers are important grid protection devices that connect different grid sources and increase the network/grid reliability. Currently, there is a clear need of increasing the numbers of switching operation. Therefore, the optimal design of these devices becomes of extreme importance in order to enable the required switching capabilities. This ...

Design and Analysis of Electro Static Drive (ESD) for the AEI 10 m Prototype

[1] Indian Institute of Technology Madras, Chennai, Tamil Nadu, India

We calculate the maximum force acting on the mirror and found it to be 0.54 µN at 700 V. The force magnitude can be improved by increasing voltage and diminishing the separation between plates. The force along X, Y-axis acts towards the center of the plates and in Z direction towards the plates to which the mass is closer.

Mung bean is a good source of protein, vitamins, certain minerals and antioxidant compounds for the vegetarian population of the country. During storage, high moisture content of mung bean leads to the maximum quality and quantity losses due to the growth of fungus and insects. Thus drying of mung bean grains is an important postharvest operation to increase the shelf life of mung bean. Infrared ...

The rotary kiln process is a commonly practiced method in the industry for producing sponge iron using coal. In the industry, there have been recent reports of premature failures of certain air tubes in a rotary kiln. Most of those cases have concentrated on those air tubes which run into the kiln around the middle portion of the kiln. This research work aims at identifying the probable cause of ...

Modeling of Decarburization in Metal Droplet in Basic Oxygen Steelmaking

Ankit [1], T. K. Kundu [1],
[1] Indian Institute of Technology Kharagpur, Kharagpur, West Bengal, India

Basic Oxygen Steelmaking is the process of refining hot metal obtained from blast furnace using oxygen. In the process, supersonic jet of oxygen is blown over the metal bath resulting in formation of droplets. The droplets mix with slag to form an emulsion in which refining reactions take place. Among those reactions, decarburization reaction is the most important one. ...

[3] Monash University, Victoria, Melbourne, Australia

The groundwater flow modelling of any typical field situation is highly complicated in terms of heterogeneity and anisotropic assumptions. In order to simplify the complexity, this poster gives the grid approach to solve the typical field problem with simple steps using GMS (MODFLOW) and ArcGIS software. In this poster Ground water flow modeling of Kosi alluvial fan in Bihar region of India has ...

Research and Development of Multiphysics Models in Support of the Conversion of the High Flux Isotope Reactor to Low Enriched Uranium Fuel

The findings presented in this report are results of a five-year effort led by the Research Reactors Division (RRD) of the Oak Ridge National Laboratory (ORNL), which is focused on research and development toward the conversion of the High Flux Isotope Reactor (HFIR) fuel from high-enriched uranium (HEU) to low-enriched uranium (LEU). This report focuses on the tasks accomplished by the ...

The Bio Inspired Tactile Sensor

N. Sabri [1]
[1] Universiti Malaysia Perlis, Malaysia

In recent years, studies on robotics have been needed, to utilise the tactile sensors for artificial skin. Researchers have been working on tactile transduction technologies which lead to many sensor prototypes and devices for robotic applications in their effort to solve the tactile sensing problems in robotics and medical industries, but they remain unsatisfactory. This project addresses the ...
