Dynamics of Axially Functionally Graded Timoshenko Beams on Linear Elastic Foundation

Abstract: The chapter presents a detailed study into dynamic behaviour of axially functionally graded (AFG) tapered Timoshenko beam on linear elastic foundation. Geometric nonlinearity is induced in the system through Von Karman strain–displacement expressions, which are inherently nonlinear. The material model is such that it exhibits continuous gradation of material properties along the length of the beam. A set of linear springs is assumed to be attached to the bottom of the beam to mathematically replicate the foundation behaviour. Governing equations of motion are derived through suitable energy principle. The free vibration study is carried out on statically deflected configuration to plot the backbone curves of the system. Forced vibration problem is solved by assuming dynamic equilibrium under maximum amplitude of excitation. Amplitude and frequency of excitation of the external transverse harmonic excitation are the controlling factors of the system response. Frequency response curves pertaining to different combinations of system parameters are furnished as benchmark results.

Hydrostatic Pressure Study of GaAsSbN/GaAs Quantum Well Based Optoelectronic Devices

Abstract: In order to investigate the effect of hydrostatic pressure and N impurities on optoelectronic properties of GaAsSbN/GaAs Quantum Well (QW), electronic band structure, band offsets, effective mass of charge carries, relative permittivity and optical gain have been calculated under the vicinity of 16 band k.p Hamiltonian. It has been anticipated that GaAsSbN/GaAs QW system would be a potential candidate for numerous optoelectronic applications such as efficient tandem solar cells, which can cover up the entire regime (850nm to 1850nm) of AM 1.5 spectra, LASER diodes for the potential applications in the 1.3−1.55 μm regime and wide range optical modulators.

Information Technology Industry: A Contagious Bubble Ball Ride Accelerating the Socio-Economic Catastrophe

Abstract: This paper focuses on the superficially created lifestyle of IT workers; one that is created against their volition with lots of free rides to bubble –balls. It also examines the overall operating characteristics of IT organizations. Present work shows, unusual working hours and stressed out social lifestyle of IT workers start draining health and other resources. Similarly very uncertain future Debt Service Coverage Ratio of IT companies results in depletion of assets in servicing debt obligations. It is highly imperative for all the stakeholders to acknowledge discontinuation of super economic performance in the long run. We were, on the contrary, frightened to observe the abnormal behavior of IT creeping and contaminating other socio-economic sectors. We hint at the disease for these peripherally impacted sectors also in this work.

Study of Non-biological Property for Identification Cancerous Skin Tissue

Abstract: In this paper, an array of inter-digitated (IDT) capacitive sensors has been designed for the detection of skin malignancy on the basis of change in dielectric permittivity of human skin tissue. Here, the IDT-based capacitive sensor is designed with a pair of rectangular-shaped identical electrodes and extended for an array to facilitate such identification. The identification process is based on change in dielectric permittivity of skin tissue to presence excess water contain. In order to do so, an electrical model of skin tissue is designed to which an excitation potential of 1 V is given to study the impedance profile of skin tissue. This impedance profile is seen to be different for cancerous skin with that of a normal one. Therefore, it can discriminate a normal skin from an affected one in terms of change in impedance profile. This work is executed in multi-physics-based simulation software.

Design optimization of erbium-doped fiber ring laser for C and L band amplification incorporating chirped fiber Bragg grating

Abstract: This paper presents simulation studies of an efficient Wavelength division multiplexed erbium doped fiber ring laser for high gain and low noise, in C band and extending up to L band region (1545–1615nm) An average gain of 3310dB and noise figure of 7dB (maxima) has been reported on optimizing the system at −30dBm/channel input signal level, 150mW pump powers and amplifier lengths of 10m and 20m respectively at room temperature The system has also been investigated for different fiber lengths, pump powers, input signal levels and temperatures Inclusion of chirped fiber Bragg grating (CFBG) provided a uniform gain over 70nm with 02dB (p-p) variation
