In recent times, farmers face a lot of problems due to birds and animals spoiling their crops by intruding into the farms. Comparatively, old methods like scare crows are not as effective as before, as the intruders realize the tactics relatively. Also, the other problems faced are forest fires destroying crops and withering of crops due to insufficient irrigation. Hence, in this work a new innovative method is adapted which protects the crops precisely. This work aims at developing a rotatory device that detects and identifies any real time moving object in its jurisdiction. This work also aims at developing a system that detects forest fires and conveys the same to the farmer instantly; and a system that irrigates the crops automatically upon requirement. On effective implementation, this work increases crop yield. It also contributes to factors like reduction in hunger overall and prevention of farmers' suicide. As a measure of cost effectiveness, the device is miniaturized to an extent where the ultrasonic sensor detects various movements in a 30 cm radius and triggers the servo motor and the sprinkler. Upon being triggered, the servo motor helps the device rotate accordingly to 180° angle. Simultaneously, the sprinkler sprinkles the water onto the detected intruder, which accounts for driving them away. The flame sensor for forest fire detection and the moisture sensor for automatic irrigation also work simultaneously. The precision and accuracy of the device will be enhanced in the future course according to the requirements.

Any applications would prefer to have the circuits which are of high speed and consumes less power. To meet these requirements, the scaling of the circuits which are generally designed using Metal Oxide Semiconductor Field Effect Transistors (MOSFET) is done. Too much scaling down of the transistors or the integrated circuits (IC) affects the channel of the transistors causing Short Channel Effects (SCEs) which in turn affecting the reliability and performance of the circuits. To avoid this issue, a substitute of MOSFET known as Fin Field Effect Transistors (FinFE T) is used in the circuits. This helps to reduce the scaling needed and also has the better performance than the MOSFETs. This work demonstrates the advantageous performance of the FinFE Ts by implementing some of the basic building blocks of the digital circuits such as Inverter, NAND gate, NOR gate, a combinational circuit like Full Adder and a sequential circuit like SR Flip Flop. The designs are simulated using HSPICE tool at 45 nm technology. The parameters such as static power dissipation, dynamic power dissipation, rise time and fall time are examined through waveforms. The circuits with MOSFETs have the higher values from the parameters than the circuits with FinFETs.

AbstractCirculating tumor cells (CTCs) are extremely scarce cells which cut off from a primary tumor and percolate into the circulation of blood flow and are, thus, critical for precise cancer detection and treatment. Deterministic lateral displacement (DLD) which exploits asymmetric splitting of laminar flow around the implanted microposts has displayed trustworthy capabilities in separating cells of varying sizes. In this research work, a microfluidic channel consisting of three symmetrically aligned inlets and outlets and embedded circular posts has been proposed which effectively separates the CTCs from lymphocytes utilizing the concept of DLD. Using a commercial software COMSOL Multiphysics 5.4, the design of the proposed microchannel has been simulated and analyzed considering an injected blood sample containing massive CTCs and slim WBCs of radii 13.5 µm and 6 µm, respectively. The proposed model of microchannel isolates the CTCs from WBCs at a comparatively higher sample mass flow rate of 4 × 10–6 kg/s and Reynolds number of 8.9 thereby operating efficiently at higher throughput, and offers excellent linearity in terms of velocity magnitude, pressure, shear rate and Reynolds number. The computational analysis of the proposed microchannel reveals that it can isolate CTCs from WBCs with better separation ratio, offers higher throughput, reduces possibilities of clogging and maintains better uniformity of pressure distribution and other flow parameters when compared with existing microchannel designs. The maximum separation ratio for CTCs and WBCs has been obtained as 84% and 96%, respectively.

Microelectromechanical system based silicon diaphragm pressure sensor using S-shaped piezoresistors with four grooves has been proposed for pressure measurement in the range of 0 to 1.02 kg.cm-2. Four voids are located between every two grooves where the piezoresistors are placed. These piezoresistors are electrically connected with aluminium wires to form a Wheatstone bridge. By introducing grooves around the diaphragm, more stress is concentrated in the void regions, resulting in high sensitivity. In addition, improvement in the performance of the sensor has been attained by modifying its geometrical dimensions. On the basis of simulation experiments, the proposed pressure sensor has achieved a high sensitivity in the range of 45.41 mV/V/Kg.cm-2 to 48.25 mV/V/kg.cm-2 by taking different lengths of piezoresistors varying from 300 μm to 120 μm. The pressure sensor has a very low nonlinearity compared to other pressure sensors within this range. The design and simulation of the proposed piezoresistive pressure sensor is carried by using COMSOL Multiphysics 5.2a.

There are different types of Microfluidic particles sorting devices have been developed, but most of those devices have limitation in terms of the relatively low throughput. In this which method has been used is Hydrodynamic Filtration through which sorting of Bacteria particles (Beads or cells) from given sample medium can be separated which are of different size. A new scheme has been describes in this paper for a continuous sorting of Bacteria particles that is Mammalian cells (K. Pneumoniea) using Lattice-Shaped and dual-depth microchannel network. Microchannels were sorted on the base of size and it is clearly showed that the angles dominate the separation efficiencies. The problem which occurs during a fluid flow is clogging due to which particles are not separated in proper way can be overcome. The Scheme presented here for a size based particle sorting can be applicable to various biological or industrial experiments for diagnosis to achieve length-dependent sorting of bispherical microparticles. Even experimented at different angles of a lattice surface at 0 or 90 degree, 15 degree, 25 degree and 35 degree for particle sorting of K. Pneumoniae particle from sample which is precisely obtained through outputs. As per the application how this simulation method may be applied to the design of efficient hydrodynamic cell in microfluidic device for size based separation is simulated.
