A Vision-Based Method to Find Fingertips in a Closed Hand
Chaudhary, Ankit,Vatwani, Kapil,Agrawal, Tushar,Raheja, J.L. Korea Information Processing Society 2012 Journal of information processing systems Vol.8 No.3
Hand gesture recognition is an important area of research in the field of Human Computer Interaction (HCI). The geometric attributes of the hand play an important role in hand shape reconstruction and gesture recognition. That said, fingertips are one of the important attributes for the detection of hand gestures and can provide valuable information from hand images. Many methods are available in scientific literature for fingertips detection with an open hand but very poor results are available for fingertips detection when the hand is closed. This paper presents a new method for the detection of fingertips in a closed hand using the corner detection method and an advanced edge detection algorithm. It is important to note that the skin color segmentation methodology did not work for fingertips detection in a closed hand. Thus the proposed method applied Gabor filter techniques for the detection of edges and then applied the corner detection algorithm for the detection of fingertips through the edges. To check the accuracy of the method, this method was tested on a vast number of images taken with a webcam. The method resulted in a higher accuracy rate of detections from the images. The method was further implemented on video for testing its validity on real time image capturing. These closed hand fingertips detection would help in controlling an electro-mechanical robotic hand via hand gesture in a natural way.

Effect of location of load on shear lag behavior of bonded steel-concrete flexural members
Ankit Bhardwaj,Ashok K. Nagpal,Sandeep Chaudhary,Vasant Matsagar 국제구조공학회 2021 Steel and Composite Structures, An International J Vol.41 No.1
Shear lag is one of the governing phenomena considered in the design of flanged flexural members. The effect of the location of load on shear lag is not well understood yet. This paper presents a study to understand the shear lag behavior in the concrete slab of bonded steel-concrete composite flexural members, conducted with the help of a developed three-dimensional finite element model. The effect of the location of load on shear lag behavior is studied with the help of twelve loading arrangements at the service and the ultimate loads. Three effective widths based on different design criteria are used to understand the effect of the location of load on effective width. These effective widths are effective width for deflection at the service load, effective width for maximum stress at the service load, and effective width for bending moment capacity at the ultimate load. The shear lag behavior is found to be significantly affected by the location of the load. Increase in scaled eccentricity causes shear lag to vary from positive to negative.

Bond Behavior in Flexural Members: Numerical Studies
Ankit Bhardwaj,Vasant Matsagar,A.K. Nagpal,Sandeep Chaudhary 한국강구조학회 2021 International Journal of Steel Structures Vol.21 No.1
Adhesive bonding has recently emerged as an alternative to shear stud connection in steel–concrete composite fl exural members. Research on adhesive-bonded steel–concrete composite fl exural members is in a preliminary stage, and the behavior of the bond layer in these structures is not well understood yet. A three-dimensional fi nite element model is developed and used to conduct the parametric investigations. The developed model is validated with experimental results available in the literature. The behavior of the bond layer is defi ned in terms of normal stress, normal strain, shear stress, and shear strain. Seven diff erent parameters are studied regarding their eff ect on the behavior of the bond layer. The parameters include load proportion factor, longitudinal distribution of load, transverse distribution of load, width of concrete slab, depth of the concrete slab, Young’s modulus of the adhesive and transverse location of the adhesive fi ber. Parametric investigations are carried out to establish the relevance of parameters in terms of their eff ect on the behavior of the bond layer. The most signifi cant parameters are identifi ed as load proportion factor, longitudinal distribution of load, and Young’s modulus of adhesive.

DNA transfer between distantly related organisms over the years by means other than reproduction is known as horizontal gene transfer (HGT). Although HGT has played a significant role in the adaptive evolution of pro karyotes, its importance in determining the evolution of eukaryotes, particularly in insect lineages, remains unknown. A thorough examination of high-quality insect genomes has revealed more than the expected number of genes from different donors, bacteria, fungi, viruses, and plants. Most of these transfers have been concen trated in higher numbers in one of the highly destructive hemipteran global insect pests, the whitefly (Bemisia tabaci). Acquisition of genes in whiteflies from different donors has provided several advantages, including synthesizing vital components (biotin, lysine, and pantothenic acid) and a recently identified involvement in detoxifying plant toxins and many other unknowns. This review highlighted recent HGT events in hemipteran insects. We detailed the number and function of the horizontally transferred genes in B. tabaci from different donors and the advantages of such transfers. We also discussed the possibility of using HGT silencing to manage B. tabaci.
