For simple structure and lower maintenance cost, electric vehicles are popular in this sub-continent. As passenger vehicles, easy bikes are being widely used in Bangladesh. Mainly, iron core transformer based bulky chargers with efficiency lower than 80% are used to charge more than 10 million easy bikes. These inefficient chargers cause huge power losses to national utility grid. Moreover, manual controls of such conventional charger are bothersome to its user. Implementations of power electronics based chargers are able to operate in more than 90% efficiency which can reduce the power losses from utility grid. A high capacity synchronous buck converter based charger with built in intelligent system is proposed in this paper. An automated charging current control system is initiated. After the simulation by using PSIM software, a lightweight prototype of easy bike charger is built and its performance is evaluated for high output current. The efficiency and its maximum rated power is observed and compared with the conventional charger.

Two bi-directional switch based three-phase buck AC voltage controller is presented in this paper. The operational principle of the proposed three-phase regulator is a direct consequence of using two three-phase bi-directional switches in the buck converter topology. The converter works on per phase basis and therefore three phase output voltages remain same in case of load unbalance. The topology has reduced number of switches for a three-phase AC voltage control having output voltage regulation, input current shaping and power factor improvement capability. Reduced number of switches allows simple control circuit, less switching loss, reliable operation and low cost. Steady state analysis and simulation results of open and closed loop control of the proposed converter are presented in this paper. The voltage mode feedback control method used for controlling the regulator shows acceptable regulation of the converter output voltage. During sudden variation of load or input voltage the controller adjusts the duty cycle to recover to the desired output voltage.

Text compression algorithm performs compression at the character level. Bangla text has some unique features such as no distinct upper and lower case letter, consonant cluster (CC) and consonant with dependent vowel sign (CV) etc. The conventional Lempel-Ziv-Welch (LZW) algorithm is not suitable for compressing Bangle text. Therefore, in this paper, we propose a modified LZW (MLZW) algorithm which can compress Bangla text effectively and efficiently. In our proposed method, a dictionary with Unicode ranges from 1–90 is used for Bangla characters. The compression process is started with checking the input character. If input character is a part of CC or CV, then CC or CV is considered as a character and search it in the dictionary. If the character to be encoded is already in dictionary, encode it with the dictionary index. Otherwise, the character is added to the dictionary and is encoded with its corresponding dictionary index. Simulation results indicate that the proposed MLZW algorithm compresses Bangla text effectively and efficiently. We observed that the proposed MLZW provides higher compression rate approximately 3% for dictionary index and 33% for output sequence compared with LZW algorithm.

Some unavoidable shortcomings of acoustic wave based communications leads to the use of low frequency electromagnetic (EM) waves for underwater vehicle communication. Electric conductivity, causing frequency dependent attenuation, limits communication distance and data transfer rate in sea environment. An enhancement in range and bandwidth can be achieved by: 1) allowing EM signals to cross seawater-to-air boundary and achieve long-range horizontal communication using air path, followed by air to water signal transmission, if needed, and 2) exploring guided waves phenomenon at the water side of the seawater-air interface. A computational investigation to compare the EM wave propagation characteristics in seawater, in both sides of the seawater-air interface within a thin layer, and in air after crossing interface, in order to determine the optimum operating frequencies, ranges of communication, antenna orientation, and vertical offset of submerged antenna is presented in this paper. It is shown that with approximately 70 dB loss of signal strength, guided electric fields through air-water interface can be transmitted to a distance of 1 km at 10 KHz when the transmitter is 5 m below the interface.

A very simple multiband multiple-input multiple-output (MIMO) antenna system is developed. The proposed antenna system consists of two alphabetic letter shaped elements: one is C-shaped and another is inverted L-shaped — all together can combinedly operate the wideband frequency range of LTE-1, 2, 3, 7, 12, 13, 14, 22, 40, 43 and WLAN bands. The C-shaped antenna element excites lower order resonance to cover lower frequency bands from 700 MHz to 800 MHz, whereas L-shaped is responsible for other higher frequency bands (1.7–3.8 GHz). The reflection coefficient is achieved 6 dB in case of LTE-2, LTE-3 LTE-12, LTE-13, LTE-14 bands, but for all other bands it is greater than 10 dB. The two U-shaped and I-shaped slots are introduced to reduce the coupling effects between two antenna unit. The isolation of this proposed MIMO antenna is achieved higher than 15 dB with a compact size of 70 × 70 × 0.8mm3 which is suitable for 4G/LTE ultra slim mobile phones and wireless devices.

This paper proposes a new and simple while cost-effective method for DC link voltage controller for a light weight electric vehicle with Permanent Magnet Synchronous Motor (PMSM) drive. A bi-directional boost converter with PI regulated variable duty cycle is used for maintaining a constant DC link voltage. Keeping the DC link voltage constant provides better performance under variable load condition. The vector controlled PMSM drive allows to follow the exact speed command for variable applied load condition. The design of direct and quadrature axis current regulator for the PMSM motor is also discussed. The DC link voltage controller along with vector control PMSM drive has been simulated in MATLAB/Simulink.

In this paper, we utilize periodic nanostructures to enhance the short circuit current density of bulk heterojunction organic solar cell. We exploit the technique of broadening the absorption spectrum efficiently using periodic nanostructures in photoactive layer to improve the short circuit current density of our solar cell. In this regard, we simulate a conventional 200 nm thick P3HT:PCBM solar cell with four different nanostructures (pillar, rectangle, pyramid, sphere) placed in the active medium and calculate the absorbed power and generation rate initially. Then, we calculate the short circuit current density with different nanostructures incorporated into it. We find that maximum short circuit current density (21.70 mA/cm2) can be achieved when pillars are incorporated and 20.21% improvement is observed at optimized condition. Finally, we extend our study by replacing P3HT:PCBM with PBDTTT-C:PCBM active layer. In the latter case, a shortened enhancement of 9.37% is observed.

Steganography is the science of hiding information in digital media that seemingly harmless. LSB replacement technique is commonly used in hiding information. Exploiting modification direction (EMD) method is a high capacity technique. EMD method uses the relationship of η adjacent pixels to embed the secret data. This method can hide (2n + 1)-ary notational secret digit into η cover pixels. Based on this method Chao et al. proposed Data Hiding Scheme with Diamond Encoding (DEMD) method which can embed (2k2 + 2k + 1)-ary secret data in a pair of pixel. Our proposed method is extension of DEMD method. A reference matrix is required for this method on the other hand our method doesn't need this matrix and also overcome the overflow problem.
