Abstract: Abstract：The air graded combustion of a coal-fired boiler of 400 MW units in a power plant was reconstructed, to see the impacts of the burnout wind and mixing biomass gas on combustion and NOx emission of coal fired boiler. Study is based on numerical simulation adding three layer separation burnout of (SOFA) to main burner. Coal combustion and pulverized coal blending was built. Simulation was carried out with pine gas and no SOFA (15% and 25% air distribution ratio) for combustion process and behavior. Different conditions were applied to analyze the NOx emission, Velocity field and temperature field. Results acquire through simulation suggest that under condition of no SOFA and only 15% SOFA wind can form a tangent circle and field of velocity is stable but burning wind is not ideal under......

Abstract: This paper proposes a miniaturized high-isolation MIMO textile antenna for 2.4GHz ISM band Wireless Body Area Network (WBAN) applications. An inverted S-type radiating element is used to reduce the overall dimension of the proposed MIMO textile antenna with very compact size of 86 mm×40 mm×1.6 mm. The proposed MIMO antenna consists of S shaped type radiator, ground and two slots. The Defected Ground Structure (DGS) are introduced in the shared ground plane of the proposed MIMO textile antenna to produce high isolation between the antenna elements. By putting two slits in a ground plane the isolation characteristic is improved and the resonant frequency can be controlled. In general, textiles present a very low dielectric constant that reduces the surface wave losses and increases the performance of the antenna. The proposed MIMO textile antenna has been designed on jeans substrate with dielectric constant εr = 1.6 and 1.6mm thickness. The proposed MIMO.....

Abstract: Multilevel inverters are power electronic devices that changes over DC to AC quantity. But these devices produces non-sinusoidal signal which contains harmonics. So as to be overcome this problem a 31-level cascaded multilevel inverter topology was developed. The proposed inverter topology has been designed based on the minimum number of switches, switching power losses and total harmonic distortion[THD] when compared to the symmetrical seven level and asymmetrical fifteen level inverter topology. The simulation results are presented showing the validity of the analysis.

Abstract: Manufacturing Assembling forms unavoidably prompt a condition of lingering worry into materials and
items. This can present potential issues, regarding dimensional dependability, Structural trustworthiness and
diminished weariness life. The traditional method to alleviate the leftover anxieties is post-weld heat treatment, which
is a successful procedure, however it experiences a few detriments: the expense of treatment as far as gear and
vitality is high. Subsequently another methodology is expected to conquer the disadvantages experienced by the
ordinary pressure easing procedures. As an expansion to the current strategies for better quality feasibility vibratory
welding method is presented. The current test is planned to dissect the impact shear weight on the lap welded mellow
steel plates of IS 2062 evaluation B, which are welded during vibration with varieties of current that is at various
amplitudes and increasing speeds. What's more, it is recognized that the shear quality is expanding while the welding
procedure is finished by offering vibrations to the work piece.

Abstract: India, whose GDP depends on the agriculture is not a developed nation in terms of modernization in
agriculture. The high cost of labor, uncertainty in the production of crops, lack of knowledge about new
methods, continuing with the same orthodox and traditional means to go about agriculture, the inefficient use of
proper irrigational facilities results in low productivity. Due to this uncertainty in the irrigation process the
crops may also dry up. About 14.7% of India's growth depends on the agricultural sector, so it's a huge cause
of concern.
With this project, the current problems related to farming are solved and practically implemented solutions are
provided. Using IOT as well as GSM, a whole new concept of farming using networks is introduced reducing
labor, updating farmer about the live conditions of farm on the mobile devices and presenting its graphical
value using thing speak. It makes the process handy with the click a button reformation..........

Abstract: Concrete is principally utilized material for the development of different kinds of structures in the
advanced time of common foundations. Concrete is solid in pressure yet it is feeble in strain and shear. To
dispense with those issues, strands were acquaint in concrete with upgrade its rigidity and shear quality. By
utilizing filaments in solid blend it changes over fragile nature of cement into flexible nature. Different Efforts
are being made in the field of solid innovation to grow such kind of cements which have exceptional attributes.
In the old time just plain and straight steel fiber were utilized. In present day advancement of fiber fortified solid
some new kind of strands like glass, carbon, polypropylene and aramid filaments are given in plain cement to
the improvement in elasticity, exhaustion qualities, shrinkage attributes, sway, flexural quality, and compressive
quality. The different properties of FRC rely upon fiber geometry, type, modulus of flexibility, solidness,
viewpoint proportion, fiber substance and fiber direction. Total size and network quality is likewise a significant
parameter of fiber fortified cement........
