Modeling of A.I based Inhalation for Advanced Life Support System Development

Present piece of idea exhibits to divert attention towards automated high precision Life Support System (LSS) instead of manual one using medical intelligence devices while treating and diagnosis to the patient, where Ventilator, inhaler and respiratory control is most important factor during operation, surgeries and in other likewise medical emergency situations to maintain proper saturation in patient lungs to sustain their lives. This work gives idea, how we can design A.I based Inhaler System for the same.&nbsp

Do Family-Controlled Malaysian Firms Create Wealth for Investors in the Context of Corporate Acquisitions?

Evidence has proved that family-controlled firms are prevalent in Malaysia and do exert considerable economic power in the country. Two possible scenarios emerge when ownership of firms become concentrated in the hands of only a few shareholders or a group of related shareholders. Firstly, the interests of related shareholders could be aligned with other non-family shareholders (Agency Problem I). Conversely, there is a possibility that related shareholders could treat themselves preferentially over the minority shareholders (Agency Problem II). Given that the ownership structures of the majority of Malaysian publically listed firms are characterised by concentrated shareholdings, protection of the interests of minority shareholders becomes critical. However, beyond anecdotal evidence, there is little empirical evidence on the relevance of minority expropriation activities to Malaysian family-controlled firms and firm value. This study investigates the corporate acquisition activities of family-controlled Malaysian firms. Corporate acquisitions are amongst the high profile corporate investment mechanisms that provide a direct meas­ure for possible expropriation of shareholder funds or value-enhancing activities. This study used classical event study methodology to examine the wealth created by corpo­rate acquisition activities of family-controlled Malaysian firms. The findings of this study found that whilst family ownership improved firm value, it could be destructive if power is entrenched by a few. The implications, especially for Malaysian policy makers, include determination of additional corporate governance framework and governmental effort to hinder concentrated family ownership in family-controlled firms. As highlighted by OECD (The Star, 2013), poor enforcement of corporate governance compliance requirements re­mains an issue for Malaysia

Gyre precoding and t-transformation-based gfdm system for uav-aided mmtc network

In this paper, an unmanned aerial vehicle (UAV)-aided multi-antenna configured downlink mmWave cooperative generalized frequency division multiplexing (GFDM) system is proposed. To provide physical layer security (PLS), a 3D controlled Lorenz mapping system is introduced. Further-more, the combination of T-transformation spreading codes, walsh Hadamard transform, and discrete Fourier transform (DFT) techniques are integrated with a novel linear multi-user multiple-input multiple-output (MU-MIMO) gyre precoding (GP) for multi-user interference reduction. Furthermore, concatenated channel-coding with multi-user beamforming weighting-aided maximum-likelihood and zero forcing (ZF) signal detection schemes for an improved bit error rate (BER) are also used. The system is then simulated with a single base station (BS), eight massive machine-type communications (mMTC) users, and two UAV relay stations (RSs). Numerical results reveal the robustness of the proposed system in terms of PLS and an achievable ergodic rate with signal-to-interference-plus-noise ratio (SINR) under the implementation of T-transformation scheme. By incorporating the 3D mobility model, brownian perturbations of the UAVs are also analyzed. An out-of-band (OOB) reduction of 320 dB with an improved BER of 1 × 10−4 in 16-QAM for a signal-to-noise ratio, Eb /N0, of 20 dB is achieved

Analytical framework of CP-free multiuser OFDM system for coordinated multi-point at mmwave

In this paper, a coordinated multipoint joint transmission (CoMP-JT) framework at mmWave for a cyclic prefix (CP)-free multiuser OFDM wireless communication system is developed and analyzed. The aim is to provide high-quality service to cell-edge users; otherwise, the cell-users would suffer from significant signal degradation due to undesired interference. The impact of complex Hadamard transform with block diagonalization channel precoding for multiuser interference reduction and designed subcarrier mapping for out-of-band (OOB) reduction are investigated. In addition, the paper studied the input back-off-aided high-power amplifier for peak-to-average power ratio (PAPR) reduction and forward error correction channel coding for improved bit error rate (BER) for cell-edge users at mmWave frequencies. Moreover, signal-to-interference-noise ratio and ergodic achievable rate are estimated both in the presence and absence of CoMP-JT-based transmission technique to verify their significance in terms of transmitted power. Numerical investigations showed an OOB reduction of 312 dB, PAPR reduction from 17.50 dB to 7.66 dB, and improved BER of 1 × 10−3 in 16-QAM for a signal-to-noise ratio of −6 dB. Hence, the simulation results demonstrated the effectiveness of the developed system

Transceiver Design for Full-duplex UAV based Zero-padded OFDM System with Physical Layer Security

In this paper, multi-antenna transceiver for zero-padded orthogonal frequency division multiplexing (OFDM) system is designed at mmWave by integrating full-duplex unmanned aerial vehicle (UAV) into the terrestrial cellular networks. Assuming that there exist no direct communication links between the ground base station (GBS) and the mobile users due to unexpected blockages from high storied buildings in urban area, the UAV applies decode-and-forward cooperative strategy on the received OFDM signals transmitted from GBS and re-transmits to the ground mobile users and passive eavesdropper. In this proposed system, intertwining logistic map (ILM)-cosine transform aided encryption algorithm combined with artificial noise enhancing physical layer security (PLS) is introduced. Also walsh-hadamard transform technique integrated with QR-decomposition based zero forcing (ZF) block diagonalization (QR-ZF-BD) precoding for multi-user interference reduction and non-iterative clipping and filtering technique for peak to average power ratio (PAPR) reduction are utilized. In addition, Low density parity check (LDPC) and repeat and accumulate (RA) channel coding with cholesky decomposition based ZF and minimum mean square error signal detection schemes for improved bit error rate (BER) are also introduced. Numerical results demonstrate the effectiveness of the proposed system in terms of PLS for color image transmission at high order digital modulation (16-PSK and 16-QAM). At the complementary cumulative distribution function of probability level 1-6%, the estimated PAPR is found to have value of 6 dB.The three users achieve BER = 1 × 10-4 at signal-to-noise ratio of 1.5 dB, 4 dB and 6 dB under RA channel coding and 16-QAM digital modulation
