  • Transforming digitization in supply chain management using artificial intelligence and machine learning
    Chintan Singh, Amrita Kumari Das
    Supply Chain Management Strategic Implementation in Manufacturing, 2024
    The industries underwent enormous transformation in the past century, which is a major economic and technical factor in the lives of nations that are connected to it. The advancement of new digital technologies as part of Industry 4.0 has made it possible to control the supply chain more effectively. In the modern, global business world, organizations that accept change and prepare for it have a chance to survive and be competitive. In order to ascertain its trending dimensions, it was therefore intended to analyze the concept of digitization and Industrial Revolution 4.0 in supply chain management. Supply chain becoming “digitalized” meant a smarter model that utilizes digital technologies like artificial intelligence (AI) and machine learning (MLn). These advances significantly strengthen the capacity for planning, sourcing, and procurement strategy. This chapter comprises explanations of the substantial benefits of MLn and AI that have been made to lowering freight costs, improving delivery efficiency, and eliminating supplier challenges all of which are beneficial for supply networks. Different AI-based business models of organizations have also been examined in an exploratory case study for operations and supply chain management. Additionally, a method for designing business models and digitization is suggested in this chapter.

    All the different studies associated with linking criminal behavior to traumatic childhood experiences have depicted that there is a variety of negative aftereffects that may include mental disorders as well as destructive behavior.
  • Crime investigating firearms: Need for cooperation between various agencies for successful prosecution
    Puneet Puri, S. K. Shukla, R. K. Sarin, Vaishali, Amrita Das, Neha Tomar
    International Journal of Medical Toxicology and Legal Medicine, 2020
    The research paper presents a case study of a criminal case involving use of firearm where the usual test firing resulted in fragmentation of bullets by defects produced inside the barrel of pistol during its manufacturing process whereas the evidence bullets recovered from the body of victim were intact. This fact itself indicates that the evidence bullets have not been discharged from the suspected firearm recovered from accused and also not proper collection/lifting of firearm discharge residue particles [FDR] from the site of injuries results in forming no definite opinion regarding presence of FDR particles around entry wounds and in estimation of range of firing. The paper also extensively discusses how close cooperation of investigating agencies and medical officers can result in successful prosecution of criminal case.

  • Synthesis and characterization of Eu3+ doped α-Al2O3 nanocrystalline powder for novel application in latent fingerprint development

    Advanced Materials Letters, 2016
    In the present study, we investigate upon the synthesis and characterization of inorganic Eu 3+ doped Al2O3 nanophosphor for its structural and luminescent properties. The luminescent nanopowder was prepared using a combustion method in which the stoichiometric ratio of oxidizers and fuel was fixed to one, with varying concentration of Eu 3+ ions acting as an activator. The prepared powder showed excellent thermal stability. For the identification of the phase and structure of the powder synthesized, X-ray diffractometer was used. From the XRD analysis, it is revealed that the rhombohedral crystallite phase of α-alumina was formed. The type of morphology and particle size was ascertained by Filed Emission-Scanning Electron Microscope (FE-SEM) and it was found that particles were having irregular spherical shape. A qualitative analysis of these nanophosphor particles was made using an Energy dispersive X-ray detector (EDS) and it was found that the samples were composed of Al, O and Eu ions. Photo-luminescence (PL) spectra were obtained using Spectrofluorometer absorption. The intense band position was observed at 618 nm and other less intense bands were also seen at 592 nm, 601 nm, 631 nm, while two weak bands were observed at 660 nm and 718 nm, when excited at 226 nm. The CIE color space chromaticity diagram was calculated from the CIE Calculator program using obtained PL spectra. The prepared nanophosphor powder was tested for latent fingerprint detection in forensic applications. The synthesized nanophosphor was successfully used as a latent fingerprint developing powder on various non-porous surfaces for forensic application.
  • Eu2+,Dy3+ codoped SrAl2O4 nanocrystalline phosphor for latent fingerprint detection in forensic applications

    Materials Research Express, 2016
    In this work, europium and dysprosium doped strontium aluminate (SrAl2O4:Eu2+,Dy3+) nanophosphor is synthesized and its novel application for the detection of latent fingerprints on various contact surfaces is reported. The SrAl2O4:Eu2+,Dy3+ is synthesized using a combustion method and shows long-lasting afterglow luminescence. The powder particles are characterized using field emission scanning electron microscopy (FE-SEM), SEM–energy dispersive x-ray analysis, x-ray diffraction and photoluminescence spectrophotometry. The FE-SEM image analysis reveals that the nanoparticles are mostly 8–15 nm in size with an irregular spherical shape. This nano-structured powder was applied to fresh and aged fingerprints deposited on porous, semi-porous and non-porous contact surfaces, such as ordinary colored paper, glossy paper, glass, aluminum foil, a yellow foil chocolate wrapper, a soft drink can, a PET bottle, a compact disc and a computer mouse. The results are reproducible and show great sensitivity and high contrast in the developed fingermark regions on these surfaces. These nanophosphor particles also show a strong and long-lasting afterglow property, making them a suitable candidate for use as a fingerprint developing agent on luminescent and highly patterned surfaces. These kinds of powders have shown that they can remove the interference from background luminescence, which is not possible using ordinary luminescent fingerprinting powders.
