Research @YorkU:<\/span><\/h4>\n

At YorkU, Amin has mainly worked on 5-Axis CNC Micromilling for Rapid, Cheap, and Background-Free NMR Microcoils. The superior mass sensitivity of microcoil technology in nuclear magnetic resonance (NMR) spectroscopy provides potential for the analysis of extremely small-mass-limited samples such as eggs, cells, and tiny organisms. For optimal performance and efficiency, the size of the microcoil should be tailored to the size of the mass-limited sample of interest, which can be costly as mass-limited samples come in many shapes and sizes. Therefore, rapid and economic microcoil production methods are needed. One method with great potential is 5-axis computer numerical control (CNC) micromilling, commonly used in the jewelry industry. Most CNC milling machines are designed to process larger objects and commonly have a precision of >25 \u03bcm (making the machining of common spiral microcoils, for example, impossible). Amin work in collaboration with research teams from YorkU and UofT on a 5-axis MiRA6 CNC milling machine, specifically designed for the jewelry industry, with a 0.3 \u03bcm precision was used to produce working planar microcoils, microstrips, and novel microsensor designs, with some tested on the NMR in less than 24 h after the start of the design process.<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div>

Research @Concordia:<\/span><\/h4>\n

At Concordia, Amin has mainly worked on Universal Amplifier Module (UAM) implemented in latest CMOS technology, that can be configured to function as a VCVS, CCCS, VCCS, CCVS and CCII. As a result, the amplifier can be used to produce four kinds of basic circuit transfer functions, i.e., voltage-, current-, transadmittance- and transimpedance- transfer functions. This is validated by presenting simulation results for second order voltage, current, transadmittance and transimpedance bandpass filter (BPF) transfer functions using only three UAM devices. The device is expected to be useful in a complex VLSI system environment where interfacing between sub-systems with varied impedance levels is required.<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div>

Research @McGill:<\/span><\/h4>\n

At McGill, Amin has mainly worked on stochastic simulation of high-speed passive distributed networks. Stochastic distributed networks can be characterized in the frequency-domain by augmented multiport Y-parameter sampled data based on a stochastic Galerkin\u2019s formulation of the network equations. In his research he proposed a Loewner Matrix approach towards generating time-domain macromodels from the augmented multiport data. The key benefit of his research is that the superior scaling of the computational complexity of the Loewner Matrix approach with respect to number of network ports is utilized to generate the macromodel much more efficiently than the traditional Vector Fitting approach.<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"_links":{"self":[{"href":"https:\/\/www.eecs.yorku.ca\/~mdaminul\/index.php\/wp-json\/wp\/v2\/pages\/9"}],"collection":[{"href":"https:\/\/www.eecs.yorku.ca\/~mdaminul\/index.php\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.eecs.yorku.ca\/~mdaminul\/index.php\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.eecs.yorku.ca\/~mdaminul\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.eecs.yorku.ca\/~mdaminul\/index.php\/wp-json\/wp\/v2\/comments?post=9"}],"version-history":[{"count":18,"href":"https:\/\/www.eecs.yorku.ca\/~mdaminul\/index.php\/wp-json\/wp\/v2\/pages\/9\/revisions"}],"predecessor-version":[{"id":342,"href":"https:\/\/www.eecs.yorku.ca\/~mdaminul\/index.php\/wp-json\/wp\/v2\/pages\/9\/revisions\/342"}],"wp:attachment":[{"href":"https:\/\/www.eecs.yorku.ca\/~mdaminul\/index.php\/wp-json\/wp\/v2\/media?parent=9"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
