FPGA Implementation of Single Neuron PID Controller for Depth of Anesthesia Based on PSO

Anesthesia is considered as one of the most important part of any surgical operation due to this it must be good monitored and controlled, i.e. the rate of infusion must be given an inappropriate dose to save the patient status in an adequate level of anesthesia. The model translates the relation between the drug used and patient response is pharmacokinetic pharmacodynamic (PK/PD). Bispectral index (BIS) is the most standard for maintaining the Anesthesia level. In this paper an optimal PID controller with neural network consists of one neuron is presented to evaluate the drug infusion rate, the system input will be the propofol drug rate, and the level of hypnosis will be the system output since it is measured during surgery from the monitor of the BIS device. optimal controller will calculate the infusion rate by using particle swarm optimization (PSO) method for tuning all the variables needed to find the optimal rate and considered it as a control signal. Then all the result is obtained by Matlab software and the hardware implantation is done using the Integrated Synthesis Environment from Xilinx ISE version 14.6 and downloaded on Spartan 3 Kit (XC3SD3400ACS484-4 by). The output results obtained from the controller in measuring the value of the infusion rate and tracking the BIS value for different patients show its efficiency and robustness in measuring the Depth of Anesthesia (DOA) correctly.
SIW-Based Leaky-Wave Antenna Supporting Wide Range of Beam Scanning Through Broadside

In this letter, a substrate integrated waveguide-based leaky-wave antenna with wide beam scanning is presented to mitigate open stopband (OSB). The unit cell of this proposed antenna consists of a longitudinal slot and a post placed oppositely offset from the center line. By introducing inductive post along with the longitudinal slot in each unit cell, the OSB is suppressed resulting in continuous beam scanning. An equivalent circuit of the proposed unit cell is developed to explain the impedance matching technique used here to suppress OSB. Dispersion diagram is also used to analyze this seamless scanning. This antenna can scan from –49° to +69° through broadside because of wide impedance matching. Finally, the antenna is prototyped and experimentally verified. Measured results are in accord with simulated results. This antenna provides maximum gain of 14.2 dBi and low level of cross polarization.
A Nested SIW Cavity-Backing Antenna for Wi-Fi/ISM Band Applications

In this communication, a cavity-backed slot antenna is proposed using substrate-integrated waveguide (SIW) technology for Wi-Fi/Industrial, Scientific, and Medical Radio band applications. This antenna comprises two SIW cavities, a rectangular and circular with a circular ring slot on the top of each cavity for radiation. The circular cavity is designed such that it is nested inside the rectangular cavity, and each one is excited by separate feedlines (microstrip and coaxial probe). By properly optimizing the antenna dimensions, it produces two frequency bands at 5.2 and 5.8 GHz with a small frequency ratio of 1.12. Finally, the design is fabricated and the results are experimentally verified. The experimental results show that the proposed antenna exhibits a −10 dB impedance bandwidth of 6% (5.04–5.35 GHz) in the lower frequency band and 3.4% (5.73–5.92 GHz) in the higher frequency band with maintaining the input port isolation better than 28 dB. Due to the SIW cavity-backing structure, the antenna shows unidirectional radiation patterns at both resonant frequencies of 5.2 and 5.8 GHz with the gain of 6.97 and 6.2 dBi, respectively. Moreover, the antenna possesses the advantages of lightweight, planar configuration, and ease of fabrication.
Enhancing Isolation in Dual-Band Meander-Line Multiple Antenna by Employing Split EBG Structure

A closely located dual-band meander-line antenna array with isolation enhancement by inserting novel split electromagnetic bandgap (EBG) uniplanar structure is proposed. The meander-line antenna is coupled to a parasitic rectangular patch to achieve the dual-band operation. Splits are applied on the surface of an EBG structure to cause decoupling at the first resonant mode and utilizing an EBG structure to decouple at the second resonant mode. The prototype of the proposed structure achieves a dual band of 180 MHz (3.42–3.6 GHz) and 400 MHz (4.7–5.1 GHz). The mutual coupling is significantly reduced by 26 and 44 dB at 3.48 and 4.88 GHz, respectively, compared to the reference antenna. In addition, the structure has high front-to-back ratio radiation characteristics.
A Polarizer Integrated Dielectric Resonator Antenna for Polarization Reconfigurability

In this communication, we introduce a p-i-n-diode-based polarizer integrated with a dielectric resonator antenna (DRA) to realize a polarization reconfigurability. The p-i-n-diode-based polarizer is found to be effective in altering the electromagnetic-field distribution of the DRA, such that the polarization of the DRA can be actively changed. Unlike conventional p-i-n-diode-based reconfigurable antennas, the proposed active polarizer would not degrade radiation performance of the DRA. In this way, the antenna retains the high radiation efficiency with its simple excitation. The proposed antenna uses a simple and agile-switching mechanism to provide three switchable polarizations to the DRA including: a <inline-formula> <tex-math notation="LaTeX">$y$ </tex-math></inline-formula>-axis polarization (STATE 1), a +45° polarization (STATE 2), and a −45° polarization (STATE 3) across a wide effective bandwidth (overlapped bands of three states) of 15.0%. The radiation efficiencies maintain 65%–79% in each state throughout the effective operating band. Finally, the experimental results agree well with the theoretical analyses.

EMG Signal Classification Using Radial Basis Function Neural Network

Classification of electromyography (EMG) signals of human arm using Radial Basis Function Neural Network (RBFNN) is presented. Using an 8-channel Myo armband, EMG signals are collected from the arm muscles. Several time domain features are extracted from the collected EMG signals; then an RBFNN is trained. In the training process, the patient moves his\her hand according to a predefined position to obtain training patterns. After the training process is completed, the trained RBFNN can recognize the patient’s intended gesture from the hand’s EMG signals and consequently the patient can control a prosthetic hand’s movements. One RBF network is trained for each extracted feature, and excellent classification results are achieved. Next, different structures of RBFNN are implemented to obtain a simpler classifier. A MATLAB program is written to train networks and record the results. The experimental results show that RBFNN is an excellent classifier with RMS error less than or equal to 10-15 for implementing a myoelectric prosthetic hand. This work is carried out by Intelligent Prosthetics Research Group (IPRG) at College of Engineering, University of Kerbala in 2018.
Proactive Conformal Antenna Array for Near-Field Beam Focusing and Steering Based on Curved Substrate Integrated Waveguide

The quadratic phase distribution on the antenna aperture is necessary to produce a near-field-focused (NFF) beam. The generation, as well as the steering of the quadratic phase distribution, is difficult for a series-fed NFF array antenna, especially for a large-aperture application. This is because the phase control capability of the planar series-fed beam-forming network is limited. In this paper, a curved substrate integrated waveguide (SIW) is employed as the feeding carrier to enhance the amplitude and phase control capability. The spatial placement of the SIW slot array antenna can be sufficiently used to synthesize the desired NFF beam. As examples, two kinds of proactive conformal SIW NFF slot array antennas, working in the standing-wave mode and the leaky-wave mode, have been developed. Both of them have the ability to generate the high-quality NFF beam. In addition, the proactive conformal SIW leaky-wave slot array antenna has the stable focal height over a wide steerable range. After careful analysis and design, these two kinds of antenna arrays are fabricated and proactively conformal to 3-D-printed frameworks with the desired shape. The theoretical analysis and simulated results are verified by experimental results.
A Review on Classification of Data Imbalance using BigData

Classification is one among the data mining function that assigns items in a collection to target categories or collection of data to provide more accurate predictions and analysis. Classification using supervised learning method aims to identify the category of the class to which a new data will fall under. With the advancement of technology and increase in the generation of real-time data from various sources like Internet, IoT and Social media it needs more processing and challenging. One such challenge in processing is data imbalance. In the imbalanced dataset, majority classes dominate over minority classes causing the machine learning classifiers to be more biased towards majority classes and also most classification algorithm predicts all the test data with majority classes. In this paper, the author analysis the data imbalance models using big data and classification algorithm.

Future Impacts of Variable Renewable Power Production : An analysis of future scenarios effects on electricity supply and demand

Many scenarios try to describe a future of supply and demand for electricity in Sweden. All the studied scenarios contain an increased amount of variable renewable energy (VRE) power production. VRE power sources, such as solar and wind power, depend on weather conditions, like solar irradiance and wind speed. There are also scenarios predicting an increased amount of plug-in electrical vehicles (PEVs), which charge their batteries from the electricity grid and thereby changes the consumption patterns. In a future power system with less nuclear power and increased VRE power production it is of interest to investigate the scenarios impact on supply and demand. The scenarios were compiled into cases for the years 2030, 2050, and 2100. Simulations of each case VRE shares resulted in hourly power production data. Aggregating the data and comparing it with the consumption gives an understanding of the power and regulation need. For Case 2030, a VRE share of 10.3% was calculated. The hydropower in Sweden could cover the power need for the whole year and even peaks in demand. For the larger shares of Case 2050 and 2100, hydropower was not able to cover peaks in power demand solemnly. The consumption of PEVs was small for all cases, reaching shares of 1.5% to 7.1%, compared to the consumption of all other sectors. Considering short-term statistics for wind power and the latest news that some of Sweden’s nuclear reactors might shut down in advance, it is possible that Case 2030 might occur sooner than predicted. If larger shares of VRE power have to be produced to meet consumer needs in the near future, grid-stabilizing measures has to be investigated.
Detecting Compiler Warning Defects Via Diversity-Guided Program Mutation

Compiler diagnostic warnings help developers identify potential programming mistakes during program compilation. However, these warnings could be erroneous due to the defects of compiler warning diagnostics. Although the existing technique (i.e., Epiphron) can automatically generate test programs for compiler warning defect detection, the effectiveness of Epiphron on defect-finding is still limited, due to the limitation for generating warning-sensitive test program structures. Therefore, in this paper, we propose a DIversity-guided PROgram Mutation approach, called DIPROM, to construct diverse warning-sensitive programs for effective compiler warning defect detection. Given a seed test program, DIPROM first removes its dead code to reduce false positive warning defects. Then, the abstract syntax tree (AST) of the test program is constructed; DIPROM iteratively mutates the structures of the AST to generate warning-sensitive program variants. To effectively construct diverse warning-sensitive structures, DIPROM applies a novel diversity-guided strategy to generate program variants in each iteration. With the generated program variants, differential testing is conducted to detect warning defects in different compilers. In the experiments, we evaluate DIPROM with two popular C compilers (i.e., GCC and Clang). Experimental results show that DIPROM significantly outperforms three state-of-the-art approaches (i.e., HiCOND, Epiphron, and Hermes) by up to 18.93%$\sim$∼76.74% in terms of the bug-finding capability on average. Meanwhile, DIPROM is efficient, which spends less time on finding the same average number of warning defects. We at last applied DIPROM to the latest development versions of GCC and Clang. After two months’ running, we reported 8 new warning defects; 5 of them have been confirmed/fixed by developers.
OPTIMUM THROUGHPUT AND PERFORMANCE EVALUATION OF MARINE TERMINALS. IN: MARITIME TRANSPORT

This paper proposes an economic approach for determining the optimum throughput and evaluation of marine terminals in a competitive environment. The engineering approach for determining optimum terminal throughput is discussed along with theoretical and empirical engineering optimum throughputs. The economic approach is necessary in a deregulated (competitive) environment in which marine terminals have become diffused because the terminals need to concern themselves with whether they can satisfy economic efficiency objectives such as profit maximization or throughput maximization in evaluating their performance.
Broadband circularly polarized moxon based antennae for RFID and GPS

Abstract-Novel circularly polarized (CP) VHF SATCOM antenna which was based on Moxon antenna (bent dipole element over a ground plane) has been extended for RFID and GPS applications. A sequence of topologies starting from a single vertical element to two vertical elements of the Moxon arms, then widened strip arm elements were investigated to understand the effects on impedance match over the widened bandwidth. The logic in this evolution was to obtain maximized gain based on Fano-Chu limits, which suggests that more metallization in the radiating configuration that fill the volume would yield higher gain for electrically small antenna. Extending the width of the strip of the equivalent dipole elements lead to a wider bandwidth and improved cross-polarization ratio. Furthermore, splitting the tapered bow tie elements increased the volume filled with radiating elements leading to improved overall performance. Ultimately extended bends at the tip of the tapered sections parallel to the ground plane helped to improve overall performance. In overall, the antenna presented here produced lower physical height, higher gain, wider bandwidth, better crosspolarization and lower back lobe radiation compared to commercial counterparts such as an eggbeater currently used in SATCOM practice as well as similar antennas in RFID and GPS applications. Here, the concept is extended to cover RFID (850-1050 MHz) and GPS (centered at 1227 and 1575 MHz) bands leading to new applications at a significant cost and size reductions and much improved performance. Prototype antennas were built based on HFSS simulations yielded better than -25 dB return loss. During simulations attention was paid to identify the effects of individual antenna elements as an optimization parameter on the overall input impedance matching over the extended bandwidth. Simulated and measured results yielded higher than industrial counterpart antenna gain, bandwidth and cross-polarization for much reduced physical dimensions.
Screening of marine fungal strains for laccase-like activities amenable to biotechnological applications

Background Environmental pollution is one of the major problems that world is facing to date. Several approaches are been studied and oxidative enzymes from microbial organisms represent an eco-friendly and cost–effective processes, amenable to biotechnological applications, as for instance industrial dye decolorization. The aim of this study was to screen marine-derived fungal strains isolated from three coastal areas in Tunisia, to identify laccase-like activities, and to produce and characterize active fungal secretomes of interest for dye decolorization. Results Following the screening of twenty fungal strains isolated from the harbours of Sfax and Monastir (Tunisia), five strains were identified displaying laccase-like activities. Molecular based taxonomic approaches allowed us to identify these strains as belonging to the species Trichoderma asperellum , Stemphylium lucomagnoense and Aspergillus nidulans . Among these five isolates, one T. asperellum strain ( T. asperellum 1) gave the highest level of secreted oxidative activities, and as such it was chosen for further studies. Optimization of the growth medium for liquid cultures was first studied to improve the level of laccase-like activity in culture supernatants. Finally, T. asperellum 1 secretome allowed decolorizing different synthetic dyes belonging to diverse dye families, in the presence or absence of 1-hydroxybenzotriazole (HBT) as a mediator. Conclusions The optimal growth conditions to produce laccase-like active secretomes from T. asperellum 1 were 1.8 mM CuSO 4 as an inducer, 1% NaCl to mimic seawater environment and 3% sucrose as a carbon source. T. asperellum 1 secretome was effective to decolorize different synthetic dyes belonging to diverse chemical classes, and the presence of HBT as a mediator improved the decolorization process.

Questionnaire Survey Methodology in Educational and Social Science Studies

Questionnaire surveys dominate the methodological designs in educational and social studies, particularly in developing countries. It is conceived practically easy to adopt study protocols under the design, and of course, most researchers would prefer using questionnaire survey studies designed in the most simple ways. Such studies provide the most economical way of gathering information from representations giving data that apply to general populations. As such, the desire for cost management and redeeming time have caused many researchers to adapt, adopt and apply the designs, even where it doesn’t qualify for the study contexts. Consequently, they are confronted by managing consistent errors and mismatching study protocols and methodologies. However, the benefits of using the design are real and popular even to novice researchers, and the problems arising from the design are always easily addressed by experienced researchers.
