An Optimize Approach to Design MUX Based Decoder Using Source Coupled Logic
Pooja Verma,Deepak Punetha,Yogita Bahuguna 보안공학연구지원센터 2016 International Journal of Hybrid Information Techno Vol.9 No.5
In Combination logic there are some patterns which commonly occur and it is convenient to represent these in their own separate units often they are also available as separate integrated circuits. This research paper covers the two of these, the decoder and the multiplexer. In this work, designing of 2:1 MUX and MUX Based Decoder using SCL (Source Coupled Logic) is done. Power and value of current spike (Rail–to-Rail current) is found for the circuits. The Simulation is done using 180nm technology using TANNER (Version 9.2) tool.

Non-convex Dynamic Economic Dispatch Using an Innovative Hybrid Algorithm
Verma Pooja,Parouha Raghav Prasad 대한전기학회 2022 Journal of Electrical Engineering & Technology Vol.17 No.2
An innovative hybrid algorithm (i h PSODE) is proposed in this paper to solve non-convex dynamic economic dispatch (DED) problem. It integrated with a novel particle swarm optimization (nPSO) and diff erential evolution (nDE). A new inertia weight, gradually varying acceleration coeffi cient and position update equation introduced in nPSO, to avoid stagnation. And in nDE a new mutation strategy and crossover rate are presented, to avoid premature convergence. Additionally, in i h PSODE after calculation identify best half member and discard rest of members from the population. In current population applied nPSO, to maintain exploration and exploitation. Then to enhance local search ability and improve convergence accuracy applied nDE. Hence, proposed i h PSODE has higher probability of avoiding local optima and it is likely to fi nd global optima more quickly. Firstly, proposed i h PSODE as well as its anticipated integrating component nPSO and nDE are testifi ed on IEEE CEC2006 constrained benchmark functions. Then performance of these proposed algorithms are evaluated with non-convex DED problem with valve-point eff ects using fi ve diff erent test systems (5-unit with losses, 10-unit without losses, 10-unit with losses, 15-unit with losses and 30-unit without losses). Several numerical and graphical experiments have been done to verify performances of proposed algorithms. Additionally, statistical and comparative analysis confi rms superiority of proposed algorithms over many state-of-the-art algorithms

Synthesis, Characterization and Antimicrobial Activity of New Thiadiazole Derivatives
Pooja Mullick,Suroor A. Khan,Surajpal Verma,Ozair Alam 대한화학회 2010 Bulletin of the Korean Chemical Society Vol.31 No.8
A series of thiadiazole derivatives were synthesized with differently substituted benzoic acids which were cyclized to give differently substituted thiazolidin-4-one. Elemental analysis, IR, 1H NMR, 13C NMR and mass spectral data confirmed the structure of the newly synthesized compounds. The derivatives of these moieties were evaluated for antimicrobial activity. Most of the synthesized compounds showed good antimicrobial activity at 200 and 100 μg/mL. Compounds showed most significant antibacterial activity against gram negative test organism Escherichia coli and most significant antifungal activity against test organisms Aspergillus niger and Candida albicans. It was observed that compounds with OCH3 at 3, 4 position of phenyl ring [5(a-l)] were more potent against microbes as compared to compounds having unsubstituted phenyl ring [4(a-l)].

Thiadiazole Derivatives as Potential Anticonvulsant Agents
Mullick, Pooja,Khan, Suroor A.,Verma, Surajpal,Alam, Ozair Korean Chemical Society 2011 Bulletin of the Korean Chemical Society Vol.32 No.3
A series of thiadiazole derivatives were synthesized with differently substituted benzoic acids which were cyclized to give differently substituted thiazolidin-4-one. Elemental analysis, IR, $^1H$ NMR, $^{13}C$ NMR and mass spectral data confirmed the structure of the synthesized compounds. The derivatives of these moieties were evaluated for anticonvulsant activity by MES model and neurotoxicity by rotarod method. The synthesized compounds showed good potential for anticonvulsant activity besides this, the compounds also showed neurotoxic effect. It was observed that compounds with $OCH_3$ at 3, 4 position of phenyl ring [5(a-l)] showed less protection against convulsions as compared to compounds having unsubstituted phenyl ring [4(a-l)].

The oldest and most extensively cultivated form of millet, known as pearl millet (<i>Pennisetum glaucum</i> (L.) R. Br. Syn. <i>Pennisetum americanum</i> (L.) Leeke), is raised over 312.00 lakh hectares in Asian and African countries. India is regarded as the significant hotspot for pearl millet diversity. In the Indian state of Haryana, where pearl millet is grown, a new and catastrophic bacterial disease known as stem rot of pearl millet spurred by the bacterium <i>Klebsiella aerogenes</i> (formerly <i>Enterobacter</i>) was first observed during fall 2018. The disease appears in form of small to long streaks on leaves, lesions on stem, and slimy rot appearance of stem. The associated bacterium showed close resemblance to <i>Klebsiella aerogenes</i> that was confirmed by a molecular evaluation based on 16S rDNA and gyrA gene nucleotide sequences. The isolates were also identified to be <i>Klebsiella aerogenes</i> based on biochemical assays, where Klebsiella isolates differed in D-trehalose and succinate alkalisation tests. During fall 2021-2023, the disease has spread all the pearl millet-growing districts of the state, extending up to 70% disease incidence in the affected fields. The disease is causing considering grain as well as fodder losses. The proposed scale, consisting of six levels (0-5), is developed where scores 0, 1, 2, 3, 4, and 5 have been categorized as highly resistant, resistant, moderately resistant, moderately susceptible, susceptible, and highly susceptible disease reaction, respectively. The disease cycle, survival of pathogen, and possible losses have also been studied to understand other features of the disease.
