Periodic perturbation method for controlling chaos for a positive output DC-DC luo converter

Abstract: A simple, non-feedback method of controlling chaos is implemented for a DC-DC converter. The weak periodic perturbation (WPP) is the control technique applied to stabilize an unstable orbit in a current-mode controlled Positive Output Luo (POL) DC-DC converter operating in a chaotic regime. With WPP, the operation of the converter is limited to stable period-1 orbit that exists in the original chaotic attractor. The proposed control strategy is implemented using simulations and the results are verified with hardware setup. The experimental results of the converter with WPP control are presented which shows the effectiveness of the control strategy

Performance Enhancement of MANET based on Cross-layered Reconfigurable Hierarchical Routing Protocol

High speed data communication is the demanding factor in both commercial and defence applications. Several algorithms are proposed to support the high-speed data exchange while ensuring the quality, performance and reliability. However, there is still a gap, citing various compatibility issues with variety of transceiver technologies. This paper proposes a novel algorithm for enhancing the performance of mobile ad-hoc networks using Free-Space Optics (FSO). The FSO has the natural ability to the interference while capable of large bandwidth and excellent compatibility. Low power and adaptability are the features with which it has contributed to the latest technologies like storage area network, wireless area network etc. The proposed work uses optical spheres with a multi-transceiver system and a cross-layered reconfigurable routing mechanism. Parameters such as delay, residual energy, throughput, and drop are verified for the Crosslayered Reconfigurable Hierarchical Routing Optical Sphere (CRHROS) protocol for varying numbers of optical transceivers. The proposed work also compares the performance of two traffic sources, Constant Bit Rate (CBR) and Variable Bit Rate (VBR), for the proposed algorithm

Economic Feasibility of Carnation Cultivation in the Nilgiris District of Tamil Nadu, India

Aim: To estimate the economics of Carnation Production under Protected cultivation, to estimate the feasibility of the protected cultivation of Carnation in the study district, and to assess the constraints faced by the farmers in scaling up the protected cultivation in the study district and to suggest suitable solutions. Study Design: An ex-post-facto study was conducted, among the carnation cultivators of Nilgiris district of Tamil Nadu. Place and Duration of Study: The Nilgiris district was purposively selected for the study as it possesses the largest area under carnation flower cultivation in Tamil Nadu and the study was conducted between April 2023 and June 2023. Methodology: The present study employed a multi-stage purposive cum random sampling technique to select the district, blocks, villages, and respondents for research. The Nilgiris district was purposefully chosen for its significance in carnation flower cultivation within Tamil Nadu. Specifically, Kothagiri, Coonoor, and Uthagai blocks of the Nilgiris district were selected as focal areas for this investigation. Within each of these selected blocks, two villages were chosen, resulting in a total of six villages as study locations. To ensure representation, 30 farmers engaged in carnation cultivation were then selected, with a proportion of 5 farmers per village. The respondents were interviewed with a pre-structured questionnaire through a random approach. Furthermore, the study incorporated feasibility analysis, which included evaluating key financial metrics such as the Benefit-Cost Ratio, Net Present Worth, and Internal Rate of Return. These financial analyses were conducted to assess the economic viability and potential returns associated with carnation cultivation in the Nilgiris district. Results: The results reveal that the net return/ 4000 m2 is Rs. 16.67 lakhs. The BCR was found to be 1.40 (Financially feasible). The NPV was found to be Rs. 70.35 lakhs and the IRR was estimated to be 40.00 per cent. Major constraints encountered by the farmers include the higher cost of polyhouse material and construction, followed by the higher cost of the seedlings and the poor availability of skilled labour. Conclusion: Protected cultivation technology unlocks the potential to produce crops with high productivity and superior quality
