The scattering effect in the environment results in color fading and contrast reduction. As a result, clarity of image is seriously degraded resulting in decreased in performance of the multimedia processing system. In this paper various challenges and issues related to restoration of hazy image are discussed in brief. Different types of dark channel prior techniques are also discussed.

Practically, this is due to the substantial presence of particles in the environment that absorb and scatter light. In computer vision, the absorption and scattering processes are commonly modeled by a linear combination of the direct attenuation and the airlight. To overcome such problem image dehazing techniques was adopted. In classic techniques dehazing was done by using some prior knowledge, but this technique gives color distortion, artifact effect etc in the output scene. In this paper we have discussed different types of Convolutional Neural Network techniques (CNN) which are based on training of dataset and overcome the problem of classic techniques.

K. Abstract: In this digital era, the flip flops are widely used for data storage. To increase the flip flops reliability, speed and power consumption, the fault resistant capacity must be improved. Therefore, it is needed to design the flip-flops for lowest average power consumption, smallest delay and area and maximum reliability with fault resistant capacity. Presently, the device scaling reduces the supply voltage requirement, transistor size, device capacitances, node charge and increases clock frequency therefore the circuits become vulnerable to the glitches. Voltage transient as a result of the collected charge is called a transient fault. In memory elements transient faults may be produced by the preceding combinational circuit glitches. Voltage supply scaling is a very efficient step to lower the power consumption. In static CMOS circuit designs, power consumption due to the glitches cannot be ignored as the portion of power consumption varies from 9% to 38% [1]. In the field of digital integrated circuits and systems, the energy-efficient circuit design is one of the great challenge for the researchers [2]. In [3-7] the authors presented novel designs which are reduced great power consumption and provide the fault free output with higher performance results. Clock network consumes more power, therefore, this is necessary to reduce the clock count. To reduce the clock count, the true single phase clock (TSPC) technique has been advised with the basic registers [8]. In [9], the authors proposed DET-FF to overcome the built-in clock overlap threat, by using true single phase clock circuits instead of an inverted clock. Power consumption in clock distribution network is very significant, which may account 45% of the total system power [10]. To reduce the clock power consumption, the clock frequency can be scaled down, by sampling the data on both of the falling and rising edges of the clock, without altering the system throughput. The DET procedure reduce the 50% power dissipation of the clock network system. Although DET designs are more complex as compared to single edge triggered (SET) designs, this can be more energy efficient [11]. The dual data rate flip flop (DDR-FF) has a lower clock load by cause of its simple configuration and lower activity factor because of its hard edge quality factor [12]. DET flip flops provide the equal data rate as SET flip-flops at the half of the clock frequency, which leading reduction in power dissipation of digital synchronous logic designs [13-14]. Therefore, we have presented a novel low power glitch resistant DET-FF which can work accurately at low voltage supply. The rest part of this paper is organized as follows. Section II includes, background study. We have discussed the proposed design in section III. Section IV explains the comparative analysis of different DET-FF designs and finally section V, concludes this work Description: Power Analysis of Novel Glitch Resistant DET-FF 2019-01-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/116 Title: CO2 gas sensing properties of Na3BiO4‑Bi2O3 mixed oxide nanostructures Authors: Gupta, Sandeep; Divakaran, Anoop Mampazhasseri; Awasthi, Kamlendra Abstract: In this paper, we report Na3BiO4-Bi2O3 mixed oxide nanoplates for carbon dioxide gas sensing applications. These nanoplates have been synthesized using electrochemical deposition with potentiostatic mode on ITO substrate and characterized using scanning electron microscopy (SEM) and X-ray difraction (XRD) to analyze their surface morphology and structure. SEM study shows the presence of horizontally aligned nanoplates stacked on top of one another (thickness ≈ 40 to 75 nm). XRD pattern shows the presence of monoclinic Na3BiO4 and Bi2O3. The gas percentage response is evaluated by measuring the change in electrical resistance of the nanoplates in the presence of carbon dioxide for diferent pressures at 50 °C, 75 °C, and 100 °C. Percentage response of more than 100% is seen at 30 psi gas pressure which increases to ≈277% at 90 psi at 100◦C.
