Function approximation via hybrid functions

Abstract: In this chapter, square integrable time functions of Lebesgue measure are approximated via hybrid functions and such approximations are compared with similar approximations using BPF and Legendre polynomials. For handling discontinuous functions, a modified method of approximation is suggested in hybrid function domain. This modified approach, named HFm approach, seems to be more accurate than the conventional HF domain technique, termed as HFc approach. The mean integral square errors (MISE) for both the approximations are computed and compared. Finally, error estimates for the SHF domain approximation and TF domain approximation are derived. The chapter contains many tables and graphs along with six illustrative examples.

System Identification: Parameter Estimation of Transfer Function

Abstract: In this chapter, parameter estimation of the transfer function of a linear system has been done employing many non-sinusoidal orthogonal function sets, e.g., block pulse functions, non-optimal block pulse functions, triangular functions, hybrid functions and sample-and-hold functions. A comparative study of the parameters estimated by different methods are made with focus on estimated errors. One numerical example has been studied extensively and ten figures and fourteen tables have been presented as illustration.

The Effects of Individuals’ Economic and Time Resource on their Information Seeking Behavior: An Inter-Individual Analysis of Information Seeking

Abstract: Objectives: This study investigates the effects of cost and time resources on information seeking trends of individual for a buying decision and observes the effects on inter-individual-level variation of behavioural pattern. Methods/ Statistical Analysis: We derive cost and time related dimensions from the data of the responses and estimate its effect on individuals information seeking. An in-depth questionnaire was administered to 307 respondents. Factor analysis, cluster analysis, multiple regression and Bayesian regression were used to identify cost and time related dimensions, finding segments of information seekers, estimating their effect on individual information seekers actions and compare between the individual level and aggregate level effect. Findings: It was found that there is a significant difference on individual’s propensity to perceived cost and incurs time and the user behavior under certain circumstances provides better results than aggregate level analysis. Previous researches on aggregate level or on individual differences use factor analysis or multiple regressions to show the personal differences but there population was always grouped according to their demographic variables, i.e. age, sex, educational level, subject specialization, working place, occupation etc. which characteristics may not act similarly at the time of searching information. In this research people are grouped according to their behavioural likeness and unlikeness. The Bayesian approach following a continuous model of heterogeneity is used in this research which evolves very rich and exemplary findings. It suggests that perceived cost has negative effect on frequency of visiting library and information center. It means that those who visit less to the library and information center tend to incur higher cost to procure information. The pricing strategy of the information may be designed accordingly. Applications/Improvements: Findings are very useful in designing information centers. If the regular information seekers can be grouped according to their behavioural characteristics, they can be served in a better way.

Tuning the resonance frequency of metamaterial nanoparticles: Silver core and PVP cladding

Abstract: Silver nanoparticles are often used as optical resonator or scatterer in different opto-electrical devices. But being a metal, high ohmic loss will occur because absorption and scattering both peaks arises at the same resonating frequency. To overcome this limitation, separation of absorption peak and scattering peak is very much needed. So in this work we present a method using metamaterial incorporating Poly Vinyl Pyrrolidone (PVP) capped silver nanoparticles which is able to decouple the absorption and scattering peak successfully with changing the thickness of the cladding layer. Study and analysis has been done to tune the resonance frequency shift between the absorption and scattering peak by varying cladding thickness. A shift of 116nm between resonating frequency of absorption and scattering efficiencies is observed for 50nm PVP cladding on core of 100nm diameter of silver nanoparticles.

Advanced Portable Exoskeleton with Self-healing Technology Assisted by AI

Abstract: The intention of this paper is to exhibit the wonderful combination of the future artificial intelligent system capable of making important decision with prompt action installed in the mechanical exoskeleton. It will follow the orders from the operator of the suit and will be comprising of nanochips to control the various function of the system. Such a system will be controlled by the human beings encoded with a single person at a time. This is recommended for the safety of the suit itself. This exoskeleton will have self-healing technology. At the time when exoskeleton is getting damaged by any man-made source, then it will start the self-healing process. The exoskeleton will not only provide the protection of the person operating it but also has a wide variety of use. The most significant part of this exoskeleton will be its self-sustaining energy production to power up the suit for its functioning. The energy producer will be environment-friendly and will not produce any toxicants. Magnetic fields will be used to yield electricity. This suit will be capable of working everywhere in air, water and land. Since this will be the first prototype of the suit, some more characteristics with developments will be presented inside. This will also be the encroachment in the field of robotics where there will be the best coordination between a machine and a human. This modernisation will defend the precious human lives fighting for redeemable civilisation.
