Computational model of an inertially governed PDMS microchannel for blood cell sorting S. Ramya, S. Praveen Kumar, M. Abinaya, D. Lingaraja, G. Dinesh Ram Aip Conference Proceedings, 2024 Recently, inertial-based microfluidic systems for cell separation have gained popularity owing to their ease of use and ultra-high throughput. Hydrodynamic forces prevail at the microchannel's top and bottom, creating two counter-rotating vortices that power these devices. The vortices form due to the centrifugal force acting as a secondary force inside the spiral form of the microchannel. This study employs COMSOL Multiphysics for a numerical simulation of dean flow dynamics based on the Navier-Stokes equation. Changing the flow rate inside a spiral microchannel allows for more efficient separation of RBCs, WBCs, and platelets, the three primary cell types found in human blood. The influence of channel Reynolds number and radius of curvature on dean flow velocity is investigated. PDMS (Poly Dimethyl Siloxane) is chosen as a material because of its flexibility and biocompatibility nature. The optimized spiral microchannel can be used for effective cell focusing and separation corresponding to their size depends on lateral hydrodynamic forces.
Electrophoretic separation of platelets using cross flow microfluidic channel for clinical assays D. Lingaraja, S. Praveen Kumar, J. Raguraman, S. Ramya, G. Dinesh Ram Aip Conference Proceedings, 2024 Microfluidic devices build benefits such as capacity to manipulate 10-9 to 10-18 L sample volume, fast analysis and on-spot detection are required for separation and analysis of biomolecules for earlier clinical assays. This paper presents the electrophoresis based separation of platelets from whole blood for the early diagnosis of illness such as thrombocytophenia and thrombocytosis. Simple cross flow microfluidic channel, utilizing focusing and filtration channels, is designed for separation based on electrophoresis and electro-osmosis principle. Blood and analyte solution is introduced into the device using the capillary forceand the separation is achieved by applying the electric potential. The concentration of different molecules along the channels is analyzed for the designed structure.
Design and comparison of seutolerant 10T memory cell for radiation environment applications S. Praveen Kumar, D. Lingaraja, V. R. Gayathri, S. Ramya, G. Dinesh Ram, T. Aravind Aip Conference Proceedings, 2024 The goal of the 10T memory cell's design is to allow it to bounce back from failure at any of the weak nodes. High stability, low power consumption, and a minimal environmental impact are important design priorities. The paper begins by proposing a 10T memory cell with appropriate transistor size and an upset physical mechanism to increase reliability in an aeronautical radiation environment. To show the efficacy of RHBD, we use Tanner Tool to stimulate the suggested idea in a TSMC 65nm CMOS process. The 10T memory cell architecture is more resilient to 0->1 and 1->0 single node upsets due to the longer read/write access time.
Design and development of effective arbitration system in a SoC S. Ramya, S. Praveen Kumar, M. Himashinii, D. Lingaraja, G. Dinesh Ram, T. Aravind Aip Conference Proceedings, 2024 As the ratio of machine masters per chip increases, system performance becomes more dependent on the arbitration procedure. The arbitrator circuit, which regulates the entitlement for colourful requestors, has an impact on the system's results. Typically, an arbitration plan is selected based on the operation. For each cycle, a memory arbitrator chooses which CPU will haveaccess. An arbitrator is used by a packet switch to select which input packet will be added to the conversation. The Round-Robin arbitration with adjustable weight of resource access time is introduced in this paper. When subvention hunger is prohibited, the round-robin arbitrator method is helpful. Each requestor's permitted time shares are quantified by the arbitrator. Giving requests in a round-robin fashion ensures at least some fairness. By weight, the requestors might order their time shares. Requestor B will get a time slice that is twice as long as Requestor A's if their respective weights are two and four, respectively. The process of verifying designs is carried out with the aid of System Verilog. Arbitrator inputs are shuffled, labour projections are calculated using an algorithm, and verification data is collected. This article includes the effort necessary to construct and verify a weighted Round-Robin arbitrator.
