Flight penetration of wind shear: Control strategies

Wind shear is a dangerous condition where there is a sharp change in the direction and magnitude of the wind velocity over a short distance or time. This condition is especially dangerous to aircraft during landing and takeoff and can cause a sudden loss of lift and thereby height at a critical time. A numerical simulation showed the effective performance of the Linear Quadratic Regulator and the Nonlinear Inverse Dynamics controllers. The major conclusions are listed and discussed

The Concept of ‘House’ in Evelyn Waugh’s Work: An Analysis of ‘Decline and fall’, ‘Vile Bodies’, ‘A Handful of Dust’, ‘Work suspended’, ‘Brideshead revisited’ & ‘Sword of Honor’

Review of six novels “Decline and fall, Vile Bodies, A handful of dust, Work suspended, Brideshead revisited & Sword of Honor” written by Evelyn Waugh shows, how the terminology “house” figures as an important factor in developing the theme in the novels. Despite many variations of theme in the different groups of his novels, taken without any chronological order, there is one particular aspect, in Waugh’s novels that reappears most constantly, that is the theme of the house; it is an element in his novels about which generalizations can most readily be made. It is a recurring symbol that seems to stand for a great deal that Waugh finds worth preserving and attaining even though it is nearly inaccessible and can rarely be presented to the reader seriously. Study indicates that the Country-‘house’ and the changing role of his father was Waugh’s concern. ‘House’ occupies an important place in novels written by Evelyn Waugh. Analysis of fictions reveals that Waugh used the character of the house in most affluent manner. ‘House’ for Waugh, symbolizes transmission of customs and beliefs, occasions, morale, and culture. While elaborating the concept of house he deals with the residents with humor, respect and with pity and sorrow. Writer follows a particular pattern while addressing the house; he treats the occupants of the house stately with comic respect. His first novel “Decline and Fall”, the perception and morality concerned with the noble house seems under threat. The fear of losing the country house is framed on the perception and conditioning rather than any form of learning. Waugh attaches values and reservations to the house. Contrary, in Vile Bodies it is analyzed that Waugh followed the same Pattern to expose the positive content and influence of the house. A number of characters - Adam, Nina, Agatha and others were portrayed in rebellion against the naturally followed customs and ceremony represented by Doubting Hall and Anchorage House. Evelyn Waugh tries to showcase the positive side of the English House instead of the eccentric, which was presented by his earlier novels. Evelyn Waugh projects the ineffectiveness of the modernization which is deficient in every attribute associated with the house. In handful of dust Evelyn Waugh seems to have developed a striking contrast between Tony’s Gothic house and Brenda’s London flat where she begins the spend most of her time later. Beaver’s mother, with whose son Brenda is committing adultery, “is subdividing a small house in Bulgaria “into six small flats at three pounds a week, of one room each and a bath”. In the novel scoop though Waugh may be whimsical or ambivalent about the attributes of Boot Magna, he is quite definite about Lord Copper’s mansion: it is “frightful”, “execrable”, where Boot encounters a page-boy whose face is “of ageless evil”. All that remains is for the world of Boot Magna to triumph finally over the world of politics, of Lord Copper and of London “that atrocious city”. In his later novels like ‘work suspended’ Evelyn Waugh begins to present the positive side of the English house instead of the eccentric, which was presented in his earlier novels. The pattern is the same. By emphasizing the positive contents and influence of the House, the novelist shows the futility of the modern age, which is devoid of every virtue, order and restraint associated with the house. The hero of Work Suspended, a novelist who is looking for a “house” recognizes that the devotion of people of his generation to domestic architecture is “wistful, half romantic, and half aesthetic”. John Plant himself is conscious of the house’s positive value, which plays a great role in forming a man’s personality. Brideshead Revisited, one of the most familiar and most disputed of country-house novels, opens sometime after the outbreak of hostilities. Like the earlier two, moreover, Waugh’s novel makes the national crisis a moment for wistfully taking stock of the English Past. In Brideshead Revisited, the challenge to order and tradition is more insidious. Brideshead stands for the ideal values of aristocracy - honor, continuity and order - to which has been added Roman Catholicism. Waugh has removed every “taint” of oddness from the place, an act that seems to reveal his “true” feelings, after all: Brideshead is positive good; the civilized rural existence (steeped in a Catholic past) is one of the last remaining outposts of sanity in a preposterous society.  In Sword of Honour,it directly concerned with the country-house theme the Crouchback seat of Broome, like the other elements just discussed, both resembles its counterparts in Waugh’s previous novels and notably differs from them at the same time. Evelyn Waugh’s funny and experimental satire of houses proclaims a new generation coming and taking on the world, they reveal the darkness and hollowness under the shining surface of high life.

Hardware Implementation of Audio Watermarking Based on DWT Transform

Presently, the duplicate copy of an audio can be generated with great ease using some smart devices, and transmitted over the internet which raises concern over copyright and privacy. Digital audio watermarking is a procedure to insert some data bits known as watermark into audio signal. Then the audio with watermark is to be transmitted to end user or made public. The proposed algorithm is used to insert a binary watermark image into a detailed coefficient of the Daubechies 9/7-based DWT transform. A watermark is dispersed consistently in low frequencies, which builds the robustness and inaudibility of the watermark data. Further, the watermark is embedded into an audio signal to have robust system against audio attacks and inaudible performance. The algorithm is verified using MATLAB and subsequently implemented on FPGA hardware to verify the real-time performance. Hardware implementation helps to embed the watermark at the same instance when audio is being captured. The results show promising application for real-time audio applications

The mean values of change in Indirect bilirubin (mg/dl) in both males and females before and after exchange transfusion was highly significant.  The mean values of change in Total bilirubin (mg/dl) in males and in females were significant

Diversification in Indian agriculture towards high-value crops: The role of smallholders

"Agricultural diversification towards high-value crops can potentially increase farm incomes, especially in a country like India where demand for high-value food products has been increasing more quickly than that for staple crops. Indian agriculture is overwhelmingly dominated by smallholders, and researchers have long debated the ability of a smallholder-dominated subsistence farm economy to diversify into riskier high-value crops. Here, we present evidence that the gradual diversification of Indian agriculture towards high-value crops exhibits a pro-smallholder bias, with smallholders playing a proportionally larger role in the cultivation of vegetables versus fruits. The observed patterns are consistent with simple comparative advantage-based production choices. The comparatively high labor endowments of the small farmers, as reflected in their greater family sizes, induce them to diversify towards vegetables. Although fruit cultivation is also labor intensive (as compared to cultivation of staples), fruits are relatively capital intensive, making them a less advantageous choice for smallholders who tend to have low capital endowments. Furthermore, both the probability of participation in fruit and vegetable cultivation as well as land allocation to horticulture decreases with the size of landholdings in India. Small or medium holders do not appear to allocate a greater share of land to fruits or vegetables. However, the share allocated to vegetables is significantly higher if the family size is bigger, while the reverse is true in the case of fruits." from Authors' Abstractdiversification, Smallholders, small farms, High value agriculture,

In the dynamic realm of deepfake detection, this work presents an innovative approach to validate video content. The methodology blends advanced 2-dimensional and 3-dimensional Convolutional Neural Networks. The 3D model is uniquely tailored to capture spatiotemporal features via sliding filters, extending through both spatial and temporal dimensions. This configuration enables nuanced pattern recognition in pixel arrangement and temporal evolution across frames. Simultaneously, the 2D model leverages EfficientNet architecture, harnessing auto-scaling in Convolutional Neural Networks. Notably, this ensemble integrates Voting Ensembles and Adaptive Weighted Ensembling. Strategic prioritization of the 3-dimensional model's output capitalizes on its exceptional spatio-temporal feature extraction. Experimental validation underscores the effectiveness of this strategy, showcasing its potential in countering deepfake generation's deceptive practices.Comment: 6 pages, 2 figure
