Wireless Wrist Pulse Monitor Design
Abstract: Wrist pulse has been used for diagnosis of disease in Ayurveda and traditional Chinese medical system. But this diagnosis is subjective to the experience and sense of the medical practitioner as same pulse may be interpreted in different way by different person. In order to make this diagnosis objective rather than subjective, digitization of wrist pulse is needed. Many platforms have been developed for acquiring the wrist pulse; however, they …

Review on Photoconductive Antenna Design from Conventional to Microstructures
Abstract: Semiconductors possess many diverse phenomena under terahertz-frequency electromagnetic radiation (THz). This is due to the fact that the energy of THz photons is at quite large scales in case of bulk and low-dimensional materials and devices. With regard to broadband THz sources, various inorganic crystals such as ZnTe/GaP/GaAs/GaSe/DAST/LiNbO3 have been used which are pumped by femtosecond laser pulses. These pulses are combined with field-resolved detection through electro-optic sampling using similar …

Solidification Curve Analysis of Cylindrical Casting by FEM
Abstract: In casting process, molten metal is solidified in mould cavity. Solidification process majorly classify into three different sections: (i) liquefaction (ii) solidify (iii) after solidification. In all three processes, one parameter which is called 'IHTC' (Intermediate Heat Transfer Coefficient), is varies with time. IHTC coefficient depends on shape, size, type of casting etc., so, it is continuously varies with all dependent functions. So, establishment of IHTC value is a very …
