In many communication systems, turbo coding Techniques for Encoding and Decoding are employed to repair errors. As compared to other error correction codes, turbo codes provide great error correcting capabilities. For the implementation of the Turbo decoder, a Very Large Scale Integration (VLSI) architecture is suggested in this study. The Maximum-a-Posteriori (MAP) algorithm is employed at the decoder side, where soft-in-soft-out decoders, interleaves, and deinterleavers are all used. The usage of the MAP algorithm reduces the quantity of iterations necessary to decode the information bits being transferred. This research employs a system for the encoder component that consists of two recursive convolutional encoders and a pseudorandom interleaver on the encoder side. Tools from Octave and Xilinx Vivado are used for the Turbo encoding and decoding. The system is synthesised and implemented using a specialised integrated circuit.

This paper is aimed to focus on bandwidth enhancement of a slot antenna with coplanar waveguide feeding. The experimentation is performed on the general CPW structure which is having a signal conductor in the middle and two ground layers etched on either side of feed with some gap to allow a unique feature of uniplanar in construction. In this context, the study of a CPW transmission line discontinuity is applied to prepare a slot antenna and this is followed by the study of incorporating serrated shape in the structure.

The majority of the world's natural water sources are not always safe to consume untreated. Raw water from rivers, lakes, ponds, and groundwater can include microorganisms. Waterborne diseases can be contracted by consuming it when pathogens in the water are spread through a drinking water distribution system. As it guarantees that water is free of dangerous microorganisms that cause water-borne diseases, disinfection is an essential water treatment technique. Different disinfection techniques are used to inactivate germs to fight waterborne illnesses. The primary goal of this essay is to describe various disinfection techniques, their applicability, limitations, and factors affecting the disinfection process. Chlorine by products and the effects of chlorine by products on people.

The clamping diode in Diode and the multilevel inverter (CHB-MLI) Inverter with Clamped Multilevel (DC-MLI). With these advantages, an inverter topology with 18 total component counts when coupled had been discovered. This proposed topology has the potential to generate up to According to the ratio allocated to its DC sources, there are 17 output levels. Aside from increasing the number of output voltage levels, this study has a relatively low number of component counts. The THD limit defined by IEEE standard is also a goal (i.e. 5 percent) all voltage applications under 69kV. To ensure that the suggested topology is functional, it is being simulated in Mat lab/Simulink with various modulation indexes. The amount of THD, the number of voltage outputs, and the RMS voltage are all being monitored and discussed. Finally, to assess the uniqueness of the suggested topology, a comparison study with recently disclosed topologies is being carried out.

A fuel cell electric vehicle (FCEV) is an electric vehicle that uses a fuel cell to power an electric motor. FCEV aims to provide customers with the benefits of battery electric vehicles such as low-to-zero emissions, high efficiency and low maintenance, without compromising on range and recharge times. A novel power management control strategy is proposed to improve the fuel cell system simulation model that is easy to use and has acceptable accuracy at the same time. The simulation model is developed through MATLAB / Simulink software using the energy macroscopic representation method, the accuracy of this method is compared with an established model. Fuel cell integration simulation analysis is performed using experimental data from a real battery car.

In this research, we present a Tri-strip monopole antenna for LTE, WLAN (Wireless Local Area Network) and WIMAX (Wireless interoperability for microwave access) Applications. This is due to the fact that wireless applications is not needed to connect all operating frequencies simultaneously, Which will effect improving functionalities without increasing size of antenna. A miniaturized triple wideband coplanar waveguide-fed patch antenna with the defected ground structure isused for LTE, WLAN and WIMAX applications. The proposed antenna with overall size of 40 mm×40 mm×1mm and the design simulation are carried on a Rogers RT/ duroid 5880 substrate using HFSS v.13.0 simulation software. The proposed antenna shows the gain of 9dB at notch band frequency therefore it is good for its working conditions. Moreover, the proposed antenna is fabricated with a new metamaterial approach by placing the unit cell we have observed the triple band notch characteristics and depth in resonant frequency. There is enhancement in gain and radiation patterns, return loss is analyzed and parametric analysis is presented for optimization of antenna. The average gain that is observed through the band is 3.5dB and the average radiation efficiency that is observed for the model is 94%.

The remainder of the pavement system is supported by the subgrade, the soil layer on top of which the subbase or pavement is constructed. The California Bearing Ratio (CBR) value of a subgrade must be at least 10. This is essential for highway engineers. Numerous studies demonstrate that if a subgrade has If the subbase material has a CBR value < 10, it will deflect under traffic loads in a similar way to the subgrade and harm the pavement. Pavement drainage and stability are provided by the subbase, a layer of aggregate material immediately beneath the pavement. The inferior, that Undrained water can freeze and expand in the layers supporting the pavement, placing intense internal strain on the pavement structure. Additionally, running water can transport debris from the subbase or subgrade and, in conjunction with traffic, pump it out of the drains. Highway engineers must consequently provide a solid, permeable subbase with longitudinal sub-drains. The effects of saturation on the stability of the soil subgrade are reviewed in this essay.

This essay is focused on the idea of suggesting an alternative fuel for diesel engines. The experiments show that the diesel-biodiesel blends can be used as substitute fuels for diesel engines. Recent studies have demonstrated that the use of diesel biodiesel blends can significantly lower emissions of carbon monoxide (CO), total hydrocarbons (HC), and particulate matter. The mixing of biodiesel with diesel significantly reduces the emission particulate matter (PM) because the blended biodiesel contains oxygen. It was recommended that some alternative fuels that are climate-friendly based on various experiments.

Castellated beam applications for diverse buildings are quickly gaining popularity. This is a result of the section's enhanced depth without adding weight, excellent strength-to-weight ratio, low maintenance requirements, and low cost of painting. Increased vertical bending stiffness, ease of service provision, and appealing appearance are the main advantages of castellated beams. Castellated beams are made by zigzaggingly cutting I sections, then rejoining them to increase the depth of the parent I sections. When castellated beams are loaded, their increased depth makes them more susceptible to web post buckling and lateral torsional buckling failure. There are numerous other forms of failure that must be considered, such as the development of flexure mechanisms, lateral torsional buckling, and vierendeel mechanisms, rupture of the welded joint in a web post, and shear buckling of a web post. A study demonstrates how using stiffeners in the beam's web part can reduce these failures. Therefore, it is necessary to do a thorough analysis of the stiffeners' number, size, and readily available places in the web part of the castellated beam. In order to explore the experimental and analytical behavior of the castellated beam with stiffeners, an attempt has been undertaken in the current paper. The outcome shows that using end stiffeners at the ends of castellated beams increases their strength and reduces their deflection.
