The most basic micromixer is a T- or Y-mixer, where two confluent streams mix due to transverse diffusion. To enhance micromixing, various modifications of T-mixers are reported such as heterogeneously charged walls, grooves on the channel base, geometric variations by introducing physical constrictions, etc. The performance of these reported designs is(More)
An HPLC method is described for the determination of drotaverine in plasma; papaverine is used as the internal standard. The lower limit of quantitation is 50 ng ml-1 with an inter-assay precision (RSD) of below 4%. The method has been validated and successfully used to assay clinical trial samples in healthy volunteers.
Efficient mixing is difficult to achieve in miniaturized devices due to the nature of low Reynolds number flow. Mixing can be intentionally induced, however, if conducting or nonconducting obstacles are embedded within the microchannel. In the case of conducting obstacles, vortices can be generated in the vicinity of the obstacle due to induced charge(More)
The performance of micro-mixers is evaluated in terms of deviations from perfectly mixed state and mixing length (i.e., device length required to achieve perfect mixing). Different variations of T-mixer are reported for improved mixing performance, including geometric constrictions/obstacles embedded in the channel wall, heterogeneously charged walls,(More)
Biomolecule gradients play an important role in the understanding of various biological processes. Typically, biological cells are exposed to linear and nonlinear concentration gradients and their response is studied for understanding cell growth, cell migration, and cell differentiation mechanisms. Recent studies have demonstrated the use of microfluidic(More)
Short term load forecasting in this paper is done by considering the sensitivity of the network load to the temperature, humidity, day type parameters (THD) and previous load and also ensuring that forecasting the load with these parameters can best be done by the Regression Line Method (RLM) and Curve Fitting Method (CFM). The analysis of the load data(More)
Droplet-based microfluidic devices have received extensive attention in the fields of chemical synthesis, biochemical analysis, lab-on-chip devices, etc. Conventional passive microfluidic hydrodynamic flow-focusing devices (HFFDs) control the droplet breakup process by manipulating the flow ratios of the continuous phase to the dispersed phase. They(More)
Digital Elevation Model (DEM) is an important input for geo-spatial analysis. For various applications like flood management, ortho rectification of remote sensing images, navigation, architectural works, defence, etc., high resolution DEM is required. TanDEM-X mission was launched in 2010 to obtain high resolution global DEM with HTRI-3 standard. SAR(More)
We present a new filter based method for the calculation of PI achievable performance for simple feedback control systems. We also extend this new approach to multiloop systems and address some key questions such as (a) what would be the performance with alternate loop pairing? (b) what performance improvement will accrue through the use of decouplers in(More)
