Face sketch is done by sketch artist for a suspected or missing person from the description of an eyewitness. These methods have been widely used by forensic investigators. It is difficult for the sketch artist to draw perfectly from such verbal descriptions given by eyewitness of scenes and hard for the informer to confirm whether the sketch looks like the real person. In this work, we proposed a conditional generative adversarial network (cGAN) for synthesizing real human face taking a sketch as an input image. The focus of our model is to generate realistic images that preserve the identity the target person verified by face recognition algorithms. The proposed cGAN has been verified on a variety of facial sketches, which confirms the effectiveness and improved facial recognition score.

Securing and hiding personal confidential information has become a challenge in these modern days. Due to the lack of security and confidentiality, forgery of confidential information can cause a big margin loss to a person. Personal confidential information needs to be securely shared and hidden with the expected recipient and he should be able to verify the information by checking its authenticity. QR codes are being used increasingly to share data for different purposes. In information communication, QR code is important because of its high data capacity. However, most existing QR code systems use insecure data format and encryption is rarely used. A user can use Secure QR Code (SQRC) technology to keep information secured and hidden. In this paper, we propose a novel SQRC system which will allow sharing authentic personal confidential information by means of QR code verification using RSA digital signature algorithm and also allow authorizing the information by means of QR code validation using RSA public key cryptographic algorithm. We implemented the proposed SQRC system and showed that the system is effective for sharing personal confidential information securely.

Nowadays Traffic jam has considered as a serious problem in city life. Sufferings due to the increment of vehicles, poor infrastructure including sluggish traffic management process have crossed the tolerance limit. In this paper, a novel technique based on an intelligent sensor network has introduced to ameliorate the running fixed time traffic controller system. Radio-Frequency Identification technique (RFID) to bring information from vehicles and Low power wide area network (LoPWAN), Wireless sensor network (WSN), Low area network (LAN), etc. are used to dispose the proposed traffic controlling system. Experimental results show that the proposed system has 98.26% accuracy in vehicle detection where Vehicle counting is faultless till the speed around 12500m/s. The proposed system is cost efficient as compared with an integrated Virtual Collaborative Conferencing System (iVCCS) system having 11.83$ cost per node. The whole system will be run in strict discipline and controlled systematically through the internet of things (IoT) to monitor the traffic of the road.

The main challenge of today's wireless network is the Quality of Service (QoS) of the medium. Now a days, many different types of Ultra High Definition (UHD) video types are introducing and online streaming of these videos are getting much popular to the users for the high quality viewing experience. But the conventional way treats all the video traffic in the same manner which may lead to the unusual delay of the real time streaming of UHD video traffic. Considering dense deployment scenario a new amendment is expecting to be announced called IEEE802.11ax on 2020 by making a big change in Physical layer features which will make faster data transmission in the network than ever. Moreover, in such huge contending situation there must need a suitable medium access control (MAC) protocol which can give priority access to UHD video traffic and can overcome the lagging experience of time critical video traffic. We have investigated this issue and proposed a novel technique to mitigate UHD video traffic scheduling problem.

The desire for wearable ultra-wideband antennas has grown up rapidly in recent years. This paper presents a wearable ultra-wideband (UWB) antenna fed by a coplanar waveguide (CPW) on paper substrate and analysis of its performance for early detection of brain stroke. A very thin sheet of paper is considered as substrate in order to make the antenna flexible, wearable, low-cost and environment friendly. The antenna shows reflection co-efficient of -10dB or less at frequencies between 1.91 GHz to 34.45 GHz. It covers the 2.36-2.4 GHz MBAN (Medical Body Area Network) band, 2.4-2.5 GHz ISM (Industrial, Scientific and Medical) band, 3.1-10.6 GHz UWB and internet of things (IoT) frequency bands and 5G communication bands. Specific Absorption Rate (SAR) is calculated placing the antenna to a 7-layer human head model only 5 mm apart in order to check the compatibility of the antenna for wearable applications. Improvement in SAR is also shown comparing with other antennas. Improvement of SAR and other simulation results of the proposed antenna make it suitable for wearable applications.

Compressive Sensing (CS) has added a great advantage in signal processing because it requires significant computation through which a Cognitive Radio (CR) user can find an opportunity in the wideband spectrum. In this paper, CS has been presented which estimates a notable part of the wideband spectrum instead of recovering the whole wideband spectrum. Some spectrum sensing approaches have been presented through which CS will be accomplished under cooperative CR network and it will be compared with the non-cooperative case in terms of Receiver Operating Characteristics (ROC). In the analysis, the fading effect of the channel has been considered and investigated under Rayleigh and Nakagami channel. At the end, the most appropriate arrangement for CS under cooperative CR network has been discovered through step by step comparative analysis.

In this study, a comprehensive idea of designing multilayer antireflection coating (ARC) on the solar cell and minimization of the overall reflectance are provided. A theoretical model for the optimization of multilayer antireflection coating for solar cell has been presented on the basis of optical interference transfer-matrix theory. Also, PCID simulation has been carried out to understand the performance of silicon solar cell of antireflection coating. Reflectance calculation for various single, double and three ARCs on silicon substrate are presented. Optical reflection values were deduced with this transfer-matrix formulation via a personal computer using MATLAB program. The reflection loss has been calculated lower than 34.66%, 8.47%, and 5.71% using single, double, and three layers respectively with high refractive index materials. External quantum efficiencies (EQEs) of 65.34% and 81.81% were obtained for the single and double layers ARCs on silicon substrate. It was also observed that the thickness of the antireflection coating should be less about 200 nm. Therefore, it is suggested that the antireflection layers proposed in this study effective to improve the efficiency of solar cell.

The foresighted fabrication of hetero-junction photovoltaic cells can be made more efficient by incorporating silicon nanoparticles synthesized from the sand of the Padma river of Bangladesh. Alumino-Thermic process was used to reduce silicon from sand and the purified silicon was then gone through the ultrasonication method to make the silicon powder of bigger diameter into nanoparticle range. Sonication time was varied and different profile distribution was observed by the DLS test. The incorporation of Si-NPs as dopant in CuO and ZnO cells increases the optical absorption and hence the band gap of the photovoltaic cells.

The skyrocketing mobile traffic demand drives the researchers to exploit the enormous spectrum in the millimeter wave (mmWave) bands (10 GHz to 300 GHZ) to facilitate high capacity backhaul channel (base stations to core network) for the next generation 5G networks. However, channel modeling is still challenging for backhaul networks due to high propagation loss, environmental attenuation, absorption loss, and sensitivity of blockage. This research will investigate a statistical mmWave channel modeling for backhaul networks in case of both line-ofsight (LOS) and non-LOS conditions at a particular mmWave band 28 GHz using by a novel simulator NYUSIM. We consider a urban macro cell scenario which operates a radio frequency bandwidth up to 800 MHz. Simulation was performed considering on some crucial parameters such as beam movements (arrival and departure), power delay profiles (omnidirectional, directional, small scale), and path losses. These investigations may be utilized to exhibit the potential of 28 GHz mmWave band and its worthy for the design of future 5G backhaul networks.

In last few years, the most accepted and prominent choice in wind farm technology is Doubly Fed Induction Generators (DFIGs). But it is vulnerable to faults, especially which relate to grid, as its stator winding is directly attached to the grid. For uninterrupted supply of power, the DFIG requires to be connected to the grid during the faults according to the grid code. Hence, improving the Fault Ride Through (FRT) capability is one of the major concerns to ensure the stable operation of DFIG based wind farms. This paper is focused on the performance of various converter-inverter topologies for transient stability analysis of DFIG. Thus far, two level and three level neutral point clamped converter-inverter topologies have been implemented in FRT analysis. However, the analysis has not yet been performed for the two newly introduced advanced topologies i.e. flying capacitor and Zsource model. Simulations had been executed using PSCAD/EMTDC simulation platform. The effect of different converter-inverter topologies on the terminal voltage and the DC-link voltage were demonstrated and compared. Simulation results show that flying capacitor model outperforms all the other converter-inverter topologies by all aspects.
