        This paper analyzes monetary policy effect on aggregate as well as sectoral output of the Indian economy for the period 1996Q1:2013Q2. We apply the standard vector autoregression (VAR) followed by impulse response function to evaluate the response of aggregate as well as sectoral output to monetary policy. We also augment the basic VAR by including various monetary transmission channels, such as, credit channel, exchange rate channel, asset price channel and direct interest rate channel and analyze the sector specific importance of each of these channels. The findings suggest that the impact of a monetary policy changes at the sectoral output level is heterogeneous. Sectors such as mining and quarrying, manufacturing, construction and trade, hotel, transport and communications seem to decline more sharply than aggregate output in response to a monetary tightening. The channels through which monetary policy is transmitted to the real economy are found to be different for every sector. In most of the cases, multiple channels are responsible for the changes in the aggregate and sectoral output to the monetary policy changes.

      • Consolidation and Permeability Properties of Pusan Clay at the Pusan New Port

        K.Ganapathi Rao,Chung, S.G.,M. Suneel 東亞大學校 建設技術硏究所 2005 硏究論文集 Vol.28 No.2

        Large reclamation projects have been carried out in the western marginal area of the Nakdong River Estuary where are located at Busan city and its vicinity, South Korea, since late 1990s. In the area studied clay deposits are unusually thick, varying from 20m to 70m in thickness. The consolidation and permeability characteristics of these clays were investigated by laboratory tests. The coefficients of consolidation and permeability of the clays in the vertical and horizontal directions were investigated by oedometer, constant rate of strain (CRS) and CRS tests with outward radial drainage. It is found from the test results that theseclays have a specific stress-strain relationship depending on the strain rate history and depositional environment, as well as a variation of permeability anisotropy during consolidation.

      • A study on response analysis of submerged floating tunnel with linear and nonlinear cables

        Yarramsetty, Poorna Chandra Rao,Domala, Vamshikrishna,Poluraju, P.,Sharma, R. Techno-Press 2019 Ocean systems engineering Vol.9 No.3

        This paper presents the comparison between SFT response with linear and nonlinear cables. The dynamic response analysis of submerged floating tunnel (SFT) is presented computationally with linear and nonlinear tension legs cables. The analysis is performed computationally for two wave directions one at 90 degrees (perpendicular) to tunnel and other at 45 degrees to the tunnel. The tension legs or cables are assumed as linear and non- linear and the analysis is also performed by assuming one tension leg or cable is failed. The Response Amplitude Operators (RAO's) are computed for first order waves, second order waves for both failure and non-failure case of cables. For first order waves- the SFT response is higher for sway and heave degree of freedom with nonlinear cables as compared with linear cables. For second order waves the SFT response in sway degree of freedom is bit higher response with linear cables as compared with nonlinear cables and the SFT in heave degree of freedom has higher response at low time periods with nonlinear cables as compared with linear cables. For irregular waves the power spectral densities (PSD's) has been computed for sway and heave degrees of freedom, at $45^0$ wave direction PSD's are higher with linear cables as compared with nonlinear cables and at $90^0$ wave direction the PSD's are higher with non-linear cables. The mooring force responses are also computed in y and z directions for linear and nonlinear cables.

        Ultrasonic study on binary liquid mixtures of propiophenone with anilines and alkyl substituted anilines at T=303.15 to 318.15 K

        Nanduri Gayatri Devi,Nanduri Veera Naga Bala Srinivasa Rao,Maganti Radha Sirija,Dittakavi Ramachandran 한국화학공학회 2018 Korean Journal of Chemical Engineering Vol.35 No.7

        Densities ‘’, ultrasonic speeds of sound ‘u’ of binary mixtures of propiophenone (PPH) with aniline, NMethylaniline, N,N-dimethylaniline and N,N-diethylaniline were measured over the entire composition range from 303.15 K to 318.15 K and at atmospheric pressure 0.1MPa. Experimental data of ultrasonic sound were compared and discussed with the computed values of ‘u’ from various velocity theories like Nomoto’s relation (UNOM), impedance relation (UIMP), Van Dael and Vangeel’s ideal mix relation (UVDV), Rao’s specific velocity relation (URAO), Junjie’s theory (UJUN) and Jouyban-Acree’s (UJOE) relation for the above binary mixtures over the entire mole fraction range at the studied temperatures. The results are satisfactory and are in agreement between the theoretical and the experimental values. Further, the molecular interaction parameter (), average percentage error and Chi-square test values were computed by using the values of experimental and theoretical ultrasonic velocities. The u values were correlated with Redlich-Kister polynomial equation to compute the coefficients and the standard deviations of the binary mixtures. The results were analyzed in terms of intermolecular interactions.

        Quasi-oppositional-based Rao algorithms for multi-objective design optimization of selected heat sinks

        R. V. Rao,R. B. Pawar 한국CDE학회 2020 Journal of computational design and engineering Vol.7 No.6

        In this paper, an endeavor is made to enhance the convergence speed of the recently proposed Rao algorithms. The new upgraded versions of Rao algorithms named as “quasi-oppositional-based Rao algorithms” are proposed in this paper. The quasi-oppositional-based learning is incorporated in the basic Rao algorithms to diversify the searching process of the algorithms. The performance of the proposed algorithms is tested on 51 unconstrained benchmark functions. Also, three multi-objective optimization case studies of different heat sinks such as a single-layered microchannel heat sink (SL-MCHS), a double-layered microchannel heat sink (DL-MCHS), and a plate-fin heat sink (PFHS) are attempted to investigate the effectiveness of the proposed algorithms in solving real-world complex engineering optimization problems. The results obtained using the proposed algorithms are compared with the results obtained using the well-known advanced optimization algorithms such as genetic algorithm (GA), artificial bee colony (ABC), differential evolution (DE), particle swarm optimization (PSO), teaching-learning-based algorithm (TLBO), Jaya algorithm, multi-objective genetic algorithm (MOGA), non-dominated sorting genetic algorithm (NSGA-II), real-coded GA (RCGA), direction-based GA, self-adaptive multi-population (SAMP) Rao algorithms, and basic Rao algorithms. The proposed quasi-oppositional-based Rao algorithms are found superior or competitive to the other optimization algorithms considered.

        A self-adaptive population Rao algorithm for optimization of selected bio-energy systems

        R. Venkata Rao,Hameer Singh Keesari 한국CDE학회 2021 Journal of computational design and engineering Vol.8 No.1

        This work proposes a metaphor-less and algorithm-specific parameter-less algorithm, named as self-adaptive population Rao algorithm, for solving the single-, multi-, and many-objective optimization problems. The proposed algorithm adapts the population size based on the improvement in the fitness value during the search process. The population is randomly divided into four sub-population groups. For each sub-population, a unique perturbation equation is randomly allocated. Each perturbation equation guides the solutions toward different regions of the search space. The performance of the proposed algorithm is examined using standard optimization benchmark problems having different characteristics in the single- and multi-objective optimization scenarios. The results of the application of the proposed algorithm are compared with those obtained by the latest advanced optimization algorithms. It is observed that the results obtained by the proposed method are superior. Furthermore, the proposed algorithm is used to identify optimum design parameters through multi-objective optimization of a fertilizer-assisted microalgae cultivation process and many-objective optimization of a compression ignition biodiesel engine system. From the results of the computational tests, it is observed that the performance of the self-adaptive population Rao algorithm is superior or competitive to the other advanced optimization algorithms. The performances of the considered bio-energy systems are improved by the application of the proposed optimization algorithm. The proposed optimization algorithm is more robust and may be easily extended to solve single-, multi-, and many-objective optimization problems of different science and engineering disciplines.

        Strain Improvement of Candida tropicalis for the Production of Xylitol: Biochemical and Physiological Characterization of Wild-type and Mutant Strain CT-OMV5

        Rao Ravella Sreenivas,Jyothi Cherukuri Pavanna,Prakasham Reddy Shetty,Rao Chaganti Subba,Sarma Ponnupalli Nageshwara,Rao Linga Venkateswar The Microbiological Society of Korea 2006 The journal of microbiology Vol.44 No.1

        Candida tropicalis was treated with ultraviolet (UV) rays, and the mutants obtained were screened for xylitol production. One of the mutants, the UV1 produced 0.81g of xylitol per gram of xylose. This was further mutated with N-methyl-N'-nitro-N-nitrosoguanidine (MNNG), and the mutants obtained were screened for xylitol production. One of the mutants (CT-OMV5) produced 0.85g/g of xylitol from xylose. Xylitol production improved to 0.87 g/g of xylose with this strain when the production medium was supplemented with urea. The CT-OMV5 mutant strain differs by 12 tests when compared to the wild-type Candida tropicalis strain. The XR activity was higher in mutant CT-OMV5. The distinct difference between the mutant and wild-type strain is the presence of numerous chlamvdospores in the mutant. In this investigation, we have demonstrated that mutagenesis was successful in generating a superior xylitol-producing strain, CT-OMV5, and uncovered distinctive biochemical and physiological characteristics of the wild-type and mutant strain, CT-OMV5.
