In this paper, Power generation from the foot overbridge using piezoelectric tile, which is constructed with the piezoelectric transducer, is being discussed. Often more, it is seen, people walk on foot overbridge. Installing piezoelectric tile (Piezotile), we can achieve the huge amount of power, a single piezotile, which has the capability to produce up to 7-watt power, eventually installing numerous piezotile, will provide us with much power, and so power generation from this way is an easy way out. To analyze the mechanical system of the piezotile convert to the electrical circuit and PID controller is used to making the system more stable and increase the accuracy in the piezoelectric transducer. It has the possibility to generate a huge amount of power and this power source has various applications in the home, street lighting, buildings, store energy, emergency power grid and so on. Energy is inconstant and furthermost energy has vanished in nature, the thought of green-energy is to renovate numerous energy into electrical energy. Piezotile is one kind of piezoelectric transducer, which transform foot stress into electric energy.

The conventional permanent magnet linear generator (PMLG) used for oceanic wave energy extraction are made of ordinary graded neodymium iron boron (NdFeB) permanent magnets (PMs). As a result, while the temperature of the generator gradually increases because of continuous operation, the generation of electrical power would be low because of demagnetization. In this paper, it is analyzed that, the conventional PMLG can not produce much electricity at high temperature because of using the ordinary graded NdFeB PMs. On the other hand, NdFeB that can maintain its remanence magnetism at high temperature saturates at low magnetic field. Therefore, high graded N48H NdFeB is proposed to be used in the PMLG to overcome this dilemma. Simulation results show that, because of using N48H PMs in the PMLG, the generated voltage, current, flux linkage and output power reaches to higher value than that of using the conventional N35 NdFeB PMs. The proposed PMLG with N48H is able to produce 28% more electrical power output than that of using the conventional N35. Finite element method is used for the simulation platform. During the simulation, same operating temperature and parameters of the PMLG is considered for both the high graded and ordinary one for fare comparisons.

In this paper, a simple D-shape photonic crystal fiber (PCF) plasmonic biosensor is proposed and analyzed. The sensor performance is investigated by applying a mode solver based finite element method (FEM). The sensing layer and plasmonic metal (gold) layer both are deposited on the external upper plane surface for comfortable and easy fabrication. The sensor exhibits the maximum sensitivity of 8000 nm/RIU and 522 RIU-1, and resolution of 1.25×10-5 RIU and 1.92×10-5 RIU using the wavelength and amplitude interrogation method, respectively, in the detection range between 1.45 and 1.48. Owing to the simple design and highly sensitive characteristics, the proposed biosensor can be precisely applicable for biomolecular analytes detection.

Machine learning algorithm suffers to recognize the Bangla handwriting from images because of the complex design, diversities among different writers and similarity between characters and digits. In recent times, deep learning is becoming very popular among the researchers for Bangla Handwriting Recgnition (BHR) because of its high efficiency i n t erms of memory, time complexity and robust feature extraction. This research aims at improving the performance of baseline Convolutional Neural Network (CNN) by increasing the recognition accuracy with minimizing the computational overhead; this paper presents a real-time Bangla Handwritten Characters and Digits Recognition (BHCDR) system using adopted CNN. Our proposed preprocessing technique, data augmentation and incorporating dropout filters i n t he b aseline C NN a rchitecture h ave achieved the goal. The proposed eight layered architecture has used two convolutional layers followed by two Maxpooling layers with 25% dropout filters from one layer to another and two fully connected layers with 50% dropout followed by a softmax classifier. The proposed model is trained and tested using 118,698 images of Bangla lekha-isolated dataset and 21000 images of CMATERdb dataset for Bangla hand-written characters and digits maintaining the ratio of 4:1 respectively. The proposed model has achieved the mean accuracy of 97.43% for classification with the average computational costs of 44.95 ms/f.

We consider the electrical load scheduling problem for a multi-chambered refrigerated warehouse with each chamber consisting of a screw compressor operating under load-unload control. Considering loading and unloading time duration of the compressors to be fixed, we propose a simple load scheduling scheme where the loading of the compressors starts with a uniform time delay. We provide analytical models to calculate the cumulative load of the warehouse compressors at any given time and the electricity cost under dynamic pricing considering the proposed load scheduling scheme. We then validate the analytical models via simulations. As a benchmark, we consider a warehouse system where the loading time of the compressors starts randomly. We investigate that the total load under the proposed scheduling scheme do not vary significantly with time. However, the traditional system has significant variation in total load with time. We compare the electricity cost of warehouses for the proposed and the traditional systems under a dynamic pricing model. We find that the proposed load scheduling scheme significantly reduces the electricity cost compared to the traditional system. However, the cost reduction decreases with increasing the loading-unloading duty cycle, i.e., with increasing the ratio of loading time duration to the total loading-unloading time duration.

A comparator establishes the bridge to connect the realms of digital and analog circuits. Moreover, the need to fulfil the consistent demand of low power and high speed small-scale devices has brought the MOS transistor based circuit design near to the edge of feasible design limit. In recent times, with the advancement in fabrication technology, FinFET has emerged as the most competent alternative with the prospective to overcome the short channel effect challenges of MOSFET. In this paper, we have presented a dynamic latch comparator circuit using 32nm PTM model of FinFET and performed our simulations with LTspice and MATLAB. Our designed comparator has shown an impressive propagation delay time of only 7.25 ps and average power consumption of 45.64 µW at 0.8V dc supply and 2.5 GHz operating frequency. Also, its performance comparisons with other contemporary designs verified the supremacy of our proposed comparator. Moreover, it seems that in the upcoming years, FinFET has the potential to bring forth radical transformation in device modeling and supersede conventional MOSFET oriented design.

Transformer coupled matching network is one of the alternative topologies for millimeter-wave integrated circuit design. Its impedance (inter-stage) transforming network (ITN) have been examined by planar and stacked topology with dimensional changing where planar transformer gives comparatively better performance than the stacked one. One-to-one-turn transformer-coupled ITN has been evaluated by the physical properties on optimum dimensional changing. Where ITN parameters and its properties function have been set below self-resonant frequencies (SRF) at 60 GHz & 79 GHz amplifiers. The quality factors (Qf)and insertion losses (IL)of transformer ITN are Qf@60GHz>20, insertion loss IL60GHz<4dB and Qf@79GHz>22, IL79GHz<3dB at their center frequency. Also, parasitic inter-winding capacitances between primary and secondary coil are minimum because of the phasor angle between these two-coil voltage goes near to 0°. At millimeter-wave, the parasitic resistances of transformer coupled ITN are coming down <3Ω form tee-type equivalent circuits of impedance matrices. Extracted Optimal values of capacitances, resistances and inductances help to increase mutual coupling coefficient as well as a good quality factor. Proposed planar and stacked small transformers have been utilized on ITN matching section of two millimeter-wave amplifiers on 55nm CMOS process. Supplying with 0.9V, mm-wave transformer coupled amplifiers have been designed layout area to 0.77 mm2 with 34.51 dB peak gain at 60 GHz and 0.46 mm2 with 17.15dB peak gain and both contain 24GHz 3dB bandwidth. As a result, it is confirmed that transformer coupled planar and modified stacked transformer are effective for shrinking layout area and high gain wideband 3dB BW in millimeter-wave regime.

This work deals with the design and simulation of patch antenna that provides resonance at frequency 9.968 GHz and applicable for RFID, WiMAX, and X-band applications. The antenna has a -10 dB impedance bandwidth of 300 MHz ranging from 9.8 GHz to 10.1 GHz. The prospect of this design is to obtain a small size, light weight and low-cost miniaturized antenna with good antenna characteristics and ease of integration using feed-networks. The basic theory and design are analyzed, and the simulation results are obtained using computer simulation technology (CST) Microwave Studio. The proposed antenna provides excellent VSWR of 1.208 and a gain of 5.960 dB. The simulated directivity, return loss (S11) and radiation efficiency are 6.015 dBi, -20.49 dB and 98.14% respectively.

The world's total population and the total number of vehicles are increasing day by day. The consumption rate of total power is also rising. Sometimes it becomes a big problem to provide the nation with enough power in underdeveloped or a developing country only because of the high-power consumption by the consumers. It is also observed that the road line continuously consumes a huge amount of electricity, and this amount of electricity can be saved if a controlled process can be operated on the road. In order to save the waste of electricity from the road and to operate street light in a controlled manner, an intelligent lighting system is introduced with a Piezo electricity generator. With the appearance of vehicles or people on the road, the light intensity can be changed in this system. This system also introduces the zebra crossing light to warn a driver at night when a person passes a road using the zebra crossing. This warning from the zebra crossing light can save a person from an accident. Another special feature of this system is the Piezoelectric generator, which provides extra electricity. In this system, several components are used to operate the system properly. Light Dependent Resistor and Ultrasonic sensor are used to control street lights by sensing night and day or by detecting vehicles or pedestrians at night. The lights at the zebra crossing point are controlled by a Passive Infrared Resistor. All these features of this system will provide an uninterrupted supply of electricity as this system can make a major contribution in saving a country's most needed energy.

The consumption rate of total power is also rising. Sometimes it becomes a big problem to provide the nation with enough power in underdeveloped or a developing country only because of the high-power consumption by the consumers. It is also observed that the road line continuously consumes a huge amount of electricity, and this amount of electricity can be saved if a controlled process can be operated on the road.
