Chapter 10 - Storage and file structure. In this chapter, we probe below the higher levels as we describe various methods for implementing the data models and languages presented in preceding chapters. We start with characteristics of the underlying storage media, such as disk and tape systems. We then define various data structures that allow fast access to data.

We present the results of a study related to phase transformation of chemically synthesized FePt nanoparticles under high pressure from face-centered cubic into face-centered tetragonal structure. As-synthesized nanoparticles are around 4.5 nm and show superparamagnetic behavior at 300 K. After annealing under 60 bar pressure of hydrogen at 400◦C for 2 h, nanoparticles exhibit strong ferromagnetic behavior with 5391 Oe coercivity.

In this chapter, we begin a discussion of file systems at the lowest level: the structure of secondary storage. We first describe the physical structure of hard disks and magnetic tapes. We then describe disk-scheduling algorithms, which schedule the order of disk I/Os to maximize performance. Next, we discuss disk formatting and management of boot blocks, damaged blocks, and swap space. We conclude with an examination of the structure of RAID systems.

This present study was elucidated the effects of different pre sowing seed treatments on stored seeds of Desi Chickpea seeds. Seeds were stored in plastic bags for one planting season, i.e. 8 months under ambient and control conditions of Prayagraj. After storage, seeds were treated with different doses of Polyethylene Glycol 6000, sodium chloride, magnetic and electric seed treatments.

Nanotechnology is the rapidly expanding field and nanoparticles are omnipresent. Biological nanoparticles are assembled from molecules or atoms synthesized in a biological system. They include magnetosomes, lipoproteins, viruses, exosomes and ferritins.. A typical instance of a protein cage possessing this native biological function is ferritin. This engineered ferritin, which has the same architecture as natural H-ferritin, is termed magnetoferritin. The iron storage protein ferritin consists of a spherical polypeptide shell (apoferritin) and accommodates various metal ions.

The systems for controlling the position of AMB’s rotor in the FESS are designed based on the emerging approaches of an adaptive neuro-fuzzy inference system (ANFIS). The results of AMB’s rotor position in the FESS indicated that the system responds with satisfactory control performance to reduce overshoot, a zero-error steady-state, and short rise time.
