  • Embryonic Architecture with Built-in Self-test and GA Evolved
           Configuration Data

    • Authors: Gayatri Malhotra, Punithavathi Duraiswamy, J.K. Kishore
      Pages: 211 - 217
      Abstract: The embryonic architecture, which draws inspiration
      from the biological process of ontogeny, has built-in
      mechanisms for self-repair. The entire genome is stored in the
      embryonic cells, allowing the data to be replicated in healthy
      cells in the event of a single cell failure in the embryonic fabric.
      A specially designed genetic algorithm (GA) is used to evolve the
      configuration information for embryonic cells. Any failed embryonic
      cell must be indicated via the proposed Built-in Self-test
      (BIST) the module of the embryonic fabric. This paper recommends
      an effective centralized BIST design for a novel embryonic fabric.
      Every embryonic cell is scanned by the proposed BIST in case
      the self-test mode is activated. The centralized BIST design uses
      less hardware than if it were integrated into each embryonic
      cell. To reduce the size of the data, the genome or configuration
      data of each embryonic cell is decoded using Cartesian Genetic
      Programming (CGP). The GA is tested for the 1-bit adder and
      2-bit comparator circuits that are implemented in the embryonic
      cell. Fault detection is possible at every function of the cell due to
      the BIST module’s design. The CGP format can also offer gate-level
      fault detection. Customized GA and BIST are combined
      with the novel embryonic architecture. In the embryonic cell, self-repair
      is accomplished via data scrubbing for transient errors.

  • Wearable Textile Antenna for Glucose Level Monitoring

    • Authors: Asha Ghodake, Balaji Hogade
      Pages: 219 - 224
      Abstract: Wearable antennas are becoming increasingly popular as a result of their wide range of applications, including communication, health parameter monitoring, and so on. If the wearable antenna is built of textile material, it is highly comfortable to wear and has numerous benefits, such as light weight, compact size, and low cost. A 1.3 GHz microstrip antenna made from jeans substrate is presented in this work. For conducting patch and ground plane copper material is used. The electromagnetic properties of the jeans substrate are dielectric constant ℇr = 1.7 and loss tangent tan ẟ = 0.01. The main application of this antenna is glucose level monitoring. Three levels of glucose, i.e., hypoglycemia, hyperglycemia, and normal glucose level, are observed using this antenna. The antenna is placed over the arm in the first scenario, while the finger is placed over the antenna patch in the second case. When the glucose concentration in the blood varies, the blood properties change, and the antenna frequency shifts as a result. That frequency shift is used to find out the three glucose levels. The advantage of jeans substrate is that you can wear this antenna very easily over your arm. The antenna was designed using HFSS software and tested using an arm phantom and a finger phantom designed in HFSS.

  • A Dual-Band Compact Integrated Rectenna for Implantable Medical Devices

    • Authors: Shamil Hamzah Hussein Alnajjr, Prof. Khalid Khalil Mohammed
      Pages: 239 - 245
      Abstract: This work describes a dual band compact fully integrated rectenna circuit for implantable medical devices. The implantable rectenna circuit consists of tunnel diode 10×10µm2 QW-ASPAT (Quantum Well Asymmetric Spacer Tunnel Layer diode) was used as the rectifier due to its temperature insensitivity and non-linearity compared with conventional SBD diodes. A miniaturized dual band implantable folded dipole antenna with multiple L-shaped conducting sections for operation in the WMTS band is 1.5GHz and ISM band of 5.8GHz. High dielectric constant material Gallium Arsenide (εr=12.94) and folded geometry helps to design compact antennas with a small footprint of 2.84mm3 (4.5×1×0.63) mm3. Four-layer human tissue model was used, where the antenna was implanted in the skin model at depth of 2mm. The 10-dB impedance bandwidths of the proposed compact antenna at 1.5GHz and 5.8GHz are 227MHz (1.4-1.63GHz) with S11 is -22.6dB and 540MHz (5.47-6.02GHz) with S11 is -23.1dB, whereas gains are -36.9dBi, and -24.3dBi, respectively. The output DC voltage and power of the rectenna using two stage rectifiers are twice that produced by the single stage at input RF power of 10dBm.

  • Method for simultaneous monitoring of uterine contractions and abdominal
           pushing in a childbirth

    • Authors: Dariusz Stanislaw Radomski
      Pages: 247 - 252
      Abstract: Effective and safe labour requires good cooperation of all the physiological systems. A proper synchronization of uterine and abdominal muscles is necessary for labour progression. Therefore, a new method for simultaneous monitoring of uterine activities and parturient’s pushing efforts is presented. A high sampled, rectified electrohysterographic signal is divided into a low, uterine passband (0.1-3.00Hz) and a high, muscular (40-100Hz) one. The time-dependent mean frequencies arse estimated for each passband separately. At the moments of uterine contraction the time-dependent LOW mean frequency was locally increased. During parturient’s  pushing effort the HIGH mean frequency was increased in the manner typical for the skeletal muscles. It seems that the proposed method would be less sensitive to a measuring noise than the previously published RMS based estimators.  Moreover, the proposed method enables to monitor fatigue of a uterus or abdominal muscles during the prolonged  2nd stage of a labour. It can be helpful to make a decision of Caesarean section.

  • Energy saving chaotic sequence based encryption, authentication and
           hashing for M2M communication of IoT device

    • Authors: Bartosz Kościug, Piotr Bilski
      Pages: 253 - 259
      Abstract: In this paper, the secure low-power Internet of Things (IoT) transmission methods for encryption and digital signature are presented. The main goal was to develop energy-efficient method to provide IoT devices with data confidentiality, integrity, and authenticity. The cryptograph energy efficient and security algorithms modifications for IoT domain were made. The novelty in our solution is the usage of encryption method popular in the image processing in the domain of the Internet of Things. Proposed modification improves immunity for the brute-force and plain-text attacks. Furthermore, we propose the modifications for hash calculation method to transform it into digital signature calculation method that is very sensitive to input parameters. The results indicate low energy consumption of both methods, however it varies significantly depending on the architecture of the devices.

  • A Concept of V2G Battery Charging Station as the Implementation of IoT and
           Cyber Physical Network System

    • Authors: Muhammad Nasir, Nelly Safitri, Rachmawati Rachmawati, Yassir Yassir, Muhammad Arhami
      Pages: 269 - 273
      Abstract: The integration of the internet of things (IoT) and cyber physical network into the battery charging station system is critical to the success and long-term viability of the vehicle to grid (V2G) trend for future automobiles in terms of environmental and energy sustainability. The goal of this article is to create a V2G battery charging station concept using the internet of things (IoT) and a cyber physical network system. The V2G charging station concept was developed with the idea that every charging electric vehicle (EV) can communicate and coordinate with the charging station's control center, which includes a cyber physical system that addresses privacy and security concerns. The communication protocol must also be considered by the charging station. The preliminary test has been taken into consideration. Normal hours (for case one), peak hours (for case two), and valley hours (for case three), respectively, were created as charging circumstances for EVs at charging stations. Simulations were run for each of the three case scenarios. Each EV's battery state of charge (SoC) is provided a 50 percent initial charge and user-defined SoC restrictions. The MATLAB/SIMULINK platform was used to run the case simulations. The grid frequency, charging station output power, and the EV's battery SoC were all observed during the 24-hour simulation. As a result, the developed V2G charging station concept can regulate its input and output power depending on the battery status of the EVs inside the charging station, as well as provide frequency regulation service to the grid while meeting the energy demand of EV customers.

      Pages: 275 - 280
      Abstract: Automatic car license plate recognition (LPR) is widely used nowadays. It involves plate localization in the image, character segmentation and optical character recognition. In this paper, a set of descriptors of image segments (characters) was proposed as well as a technique of multi-stage classification of letters and digits using cascade of neural network and several parallel Random Forest or classification tree or rule list classifiers. The proposed solution was applied to automated recognition of number plates which are composed of capital Latin letters and Arabic numerals. The paper presents an analysis of the accuracy of the obtained classifiers. The time needed to build the classifier and the time needed to classify characters using it are also presented.

  • Discretization Method of Continuous-Time Dynamic Linear Model

    • Authors: Sławomir Gryś, Waldemar Minkina
      Pages: 281 - 286
      Abstract: The article presents a new discretization method
      of a continuous-time linear model of sensor dynamics. It can be useful to reduce measuring errors related to the inertia of the sensor. For example it is important in the measurement of rapid processes as temperature changes in combustion chambers, or for shortening the time needed to establish the sensor readings in a transition state. There is assumed that sensor dynamics can be approximated by linear differential equation or transfer function. The searched coefficients of equivalent difference equation or discrete transfer function are obtained from Taylor expansion of a sensor output signal and then on the solution of the linear set of equations. The method does not require decomposition of sensor transfer function for zeros and poles and can be applied to the case of transfer function with zeros equal to zero. The method was used to compensate the dynamics of sensor measuring fast signals. The Bode characteristics of a compensator were compared with others derived using classical methods of discretization of linear models. Additionally, signals in time were presented to show the dynamic error before and after compensation.

  • Audio Compression using a Modified Vector Quantization algorithm for
           Mastering Applications

    • Authors: Shajin Prince, Bini D, Alfred Kirubaraj A, Samson Immanuel J, Surya M
      Pages: 287 - 292
      Abstract: Audio data compression is used to reduce the transmission bandwidth and storage requirements of audio data. It is the second stage in the audio mastering process with audio equalization being the first stage. Compression algorithms such as BSAC, MP3 and AAC are used as standards in this paper. The challenge faced in audio compression is compressing the signal at low bit rates. The previous algorithms which work well at low bit rates cannot be dominant at higher bit rates and vice-versa. This paper proposes an altered form of vector quantization algorithm which produces a scalable bit stream which has a number of fine layers of audio fidelity. This modified form of the vector quantization algorithm is used to generate a perceptually audio coder which is scalable and uses the quantization and encoding stages which are responsible for the psychoacoustic and arithmetical terminations that are actually detached as practically all the data detached during the prediction phases at the encoder side is supplemented towards the audio signal at decoder stage. Therefore, clearly the quantization phase which is modified to produce a bit stream which is scalable. This modified algorithm works well at both lower and higher bit rates. Subjective evaluations were done by audio professionals using the MUSHRA test and the mean normalized scores at various bit rates was noted and compared with the previous algorithms.

  • An IEEE 802.11 MAC Layer Covert Channel Based On Supported Rates

    • Authors: Geovani Teca, Marek Natkaniec
      Pages: 293 - 299
      Abstract: Wireless Local Area Networks present several vulnerabilities that are exploited, and as a result, numerous attacks have been developed and used against them. Although countermeasures to detect and eliminate such threats have been created throughout the years, few methods exist to prevent the attacks. IEEE 802.11 covert channels could be considered a candidate to prevent Wi-Fi attacks since they allow secret communication between the client station and the access point without establishing an association. They can be implemented in frames that attackers do not target. This paper presents a new covert channel that prevents Wi-Fi attacks. We also describe metrics, and discuss the performance results of the proposed solution. We show that the new protocol is able to achieve high efficiency of operation.

    • Authors: Olha Kovalchuk, Mykhailo Kasianchuk, Mikolaj Karpinski, Ruslan Shevchuk
      Pages: 301 - 307
      Abstract: In the digital society, states’ information security has become one of the key elements of ensuring the competitiveness and sustainable development of the state, guaranteeing its integrity and security in general. An important component of state security is the internal security of the state, which must ensure the personal and public safety of its citizens. Modern Ukraine is building a new system of criminal justice, which requires a new information system for risk assessment and support for optimal decision-making. Today, applied research and the development of information and analytical software for the internal security of the state have acquired a special meaning.In the paper, there is built a set of models for providing operational information for decision-making in criminal justice. This is a cluster model for creating criminal profiles of convicts, and a scoring model for identifying individual characteristics of criminals that have the greatest impact on their propensity to re-offend. The obtained models can provide reliable support for decision-making in the field of criminal justice and become part of the information support system for the internal security of Ukraine in general.

  • Design and Implementation of Intrusion Detection Systems using RPL and
           AOVD Protocols-based Wireless Sensor Networks

    • Authors: Joseph Kipongo, Theo G. Swart, Ebenezer Esenogho
      Pages: 309 - 318
      Abstract: Wireless Sensor Network (WSN) technology has grown in importance in recent years. All WSN implementations need secure data transmission between sensor nodes and base stations. Sensor node attacks introduce new threats to the WSN. As a result, an appropriate Intrusion Detection System (IDS) is required in WSN for defending against security attacks and detecting attacks on sensor nodes. In this study, we use the Routing Protocol for Low Power and Lossy Networks (RPL) for addressing security services in WSN by identifying IDS with a network size of more or less 20 nodes and introducing 10% malicious nodes. The method described above is used on Cooja in the VMware virtual machine Workstation with the InstantContiki2.7 operating system. To track the movement of nodes, find network attacks, and spot dropped packets during IDS in WSN, an algorithm is implemented in the Network Simulator (NS2) using the Ad-hoc On-Demand Distance Vector (AODV) protocol in the Linux operating system.Keywords—Intrusion Detection Systems, wireless sensor networks, Cooja simulator, sensor nodes, NS2

    • Authors: Andrzej Marek Borys
      Pages: 319 - 324
      Abstract: In this paper, we show why the descriptions of the sampled signal used in calculation of its spectrum, that are used in the literature, are not correct. And this finding applies to both kinds of descriptions: the ones which follow from an idealized way of modelling of the signal sampling operation as well as those which take into account its non-idealities. The correct signal description, that results directly from the way A/D converters work (regardless of their architecture), is presented and dis-cussed here in detail. Many figures included in the text help in its understanding.

  • The improvement of fiber-detection method to enhance the output of
           amplify-received relaying on FSO communications

    • Authors: Ucuk Darusalam, Purnomo Sidi Priambodo, Fitri Yuli Zulkifli, Eko Tjipto Rahardjo
      Pages: 325 - 333
      Abstract: The performance of free-space optical (FSO) communications that using an optical amplifier (OA) in the scheme of an amplify-received (AR)-relaying has a major drawback in the detection of input signal quality under the effects of turbulence. As an OA is based on a fiber-detection (FD) method to receive and delivers a signal at the amplification process stage, there is an opportunity to implement an optical filter to improve the quality of the input signal. In this paper, as the continuation of previous work on improvement of direct-detection, the optical filter is applied on the AR-relaying of optical signal detection, implementing an OA in the receiver. The novelty proposed in this work is the improvement of FD method where the OF is designed as the integration of cone reflector, pinhole and multi-mode fiber with an OA. The optical filter produces an optical signal, the input of the OA, which minimizes the effects of turbulence, background noise and the fluctuation of the signal spectral. Thus, OA in AR-relaying produces signal output with high power and rise up below threshold level. Additionally, an OF with a lower pinhole diameter produces the best quality of the signal spectral to be delivered into an EDFA. Through this implementation, the performance of optical relaying network on FSO can be significantly improved.

  • Analysis of Latency-Aware Network Slicing in 5G Packet xHaul Networks

    • Authors: Mirosław Klinkowski
      Pages: 335 - 340
      Abstract: Packet-switched xHaul networks are a scalable solution enabling convergent transport of diverse types of radio data flows, such as fronthaul/midhaul/backhaul (FH/MH/BH) flows, between remote sites and a central site (hub) in 5G radio access networks (RANs). Such networks can be realized using the cost-efficient Ethernet technology, which enhanced with time-sensitive networking (TSN) features allows for prioritized transmission of latency-sensitive fronthaul flows. Provisioning of multiple types of 5G services of different service requirements in a shared network, commonly referred to as network slicing, requires adequate handling of transported data flows in order to satisfy particular service/slice requirements. In this work, we investigate two traffic prioritization policies, namely, flow-aware (FA) and latency-aware (LA), in a packet-switched xHaul network supporting slices of different latency requirements. We evaluate the effectiveness of the policies in a network-planning case study, where virtualized radio processing resources allocated at the processing pool (PP) facilities, for two slices related to enhanced mobile broadband (eMBB) and ultra-reliable low latency communications (URLLC) services, are subject to optimization. Using numerical experiments, we analyze PP cost savings from applying the LA policy (vs. FA) in various network scenarios. The savings in active PPs reach up to 40%-60% in ring scenarios and 30% in a mesh network, whereas the gains in overall PP cost are up to 20% for the cost values assumed in the analysis.

      Pages: 341 - 352
      Abstract: The unpredictable and huge data generation nowadays by smart devices from IoT and mobile Crowd Sensing applications like (Sensors, smartphones, Wi-Fi routers) need processing power and storage. Cloud provides these capabilities to serve organizations and customers, but when using cloud appear some limitations, the most important of these limitations are Resource Allocation and Task Scheduling. The resource allocation process is a mechanism that ensures allocation virtual machine when there are multiple applications that require various resources such as CPU and I/O memory. Whereas scheduling is the process of determining the sequence in which these tasks come and depart the resources in order to maximize efficiency. In this paper we tried to highlight the most relevant difficulties that cloud computing is now facing. We presented a comprehensive review of resource allocation and scheduling techniques to overcome these limitations. Finally, the previous techniques and strategies for allocation and scheduling have been compared in a table with their drawbacks.

      Abstract: Energy consumed by the  sensor nodes are more sporadic in a sensor networks. A skilled way to bring down energy consumption and extend maximum life-time of any sensor present can be of evenly and unevenly distributed random area networks. Cluster heads are more responsible for the links between the source and destination. Energy consumption are much compare to member nodes of the network. Re-clustering will take place if the connectivity in the distributed network failure occurs in between the cluster networks  that will affects redundancy in the network efficiency. Hence, we propose  pragmatic distribution based routing cluster lifetime using fitness function (PDBRC) prototype  is better than the existing protocol using MATLAB 2021a simulation tool.

  • PCA based components selection criteria for computationally efficient
           Physical Layer Key Generation (PLKG) system

    • Authors: Tapesh Sarsodia, Uma Rathore Bhatt, Raksha Upadhyay, Vijay Bhat
      Pages: 361 - 369
      Abstract: Data security is one of the prime concerns in wireless networks. PLKG has been emerging as an attractive alternative to traditional cryptographic techniques. PLKG is more computationally efficient than cryptography. Moreover, PLKG using Principal component analysis (PCA) as pre-processing may further save computations. This paper proposes three mechanisms to select components of PCA which are based on Information content, Mean and Histfit. Bit Disagreement Rate (BDR) is compared for each mechanism. Histfit based method is found to be best. Since only two components are supposed to be processed for key generation, it is computationally efficient/ power efficient too.

  • Shared-Semaphored Cache Implementation for Parallel Program Execution in
           Multi-Core Systems

    • Authors: Adam Milik, Michał Walichiewicz
      Pages: 371 - 382
      Abstract: The paper brings forward the idea of multi-threaded
      computation synchronization based on the shared semaphored
      cache in the multi-core CPUs. It is dedicated to the implementation
      of multi-core PLC control, embedded solution or parallel
      computation of models described using hardware description languages.
      The shared semaphored cache is implemented as guarded
      memory cells within a dedicated section of the cache memory that
      is shared by multiple cores. This enables the cores to speed up the
      data exchange and seamlessly synchronize the computation. The
      idea has been verified by creating a multi-core system model using
      Verilog HDL. The simulation of task synchronization methods
      allows for proving the benefits of shared semaphored memory
      cells over standard synchronization methods. The proposed idea
      enhances the computation in the algorithms that consist of
      relatively short tasks that can be processed in parallel and
      requires fast synchronization mechanisms to avoid data race

  • Solving the problem of discrete process control synthesis using
           optimization on a sliding interval

    • Authors: Zhazira Julayeva, Waldemar Wójcik, Gulzhan Kashaganova, Kulzhan Togzhanova, Saken Mambetov
      Pages: 383 - 389
      Abstract: The paper presents a solution to the problem of synthesis of control with respect to the sliding interval length for the optimization of a class of discrete linear multidimensional objects with a quadratic performance criterion. The equation of motion of a closed multidimensional discrete system in the general non-stationary case is derived based on the length of the optimization interval and their main properties. The closed-loop is fitted with a signal representing the predicted values averaged over the whole sliding interval of optimization with a certain weight. A problem with a sliding optimization interval may not require a real-time solution by means of a sequence of solutions on compressed intervals. Therefore, the study of control systems with optimization on a sliding interval is of undoubted interest for a number of practically important control problems.

  • Quantum Europe, Quantum Poland

    • Authors: Ryszard S. Romaniuk
      Pages: 391 - 398
      Abstract: Quantum Information Technologies promises are very serious, greatly exceeding only technical and market levels. Development of QIT in Europe, treated as building a new infrastructural civilization level, requires a broader view of coordination, funding and priority-setting policy. Simple measures used in the case of the development of new technologies, but not creating a significant ecosystem, are insufficient in this case. Quantum technologies are poised to create a new information layer of knowledge-based society. In this essay, the author subjectively addresses some of the issues such as: what we already know and what we don't know, and what efforts are being made in Europe.

  • Selected Advances of Quantum Biophotonics – a Short Review

    • Authors: Marcin Lelit, Andrzej Białecki, Tomasz Gabler, Filip Łabaj, Emil Pituła, Ryszard Romaniuk
      Pages: 399 - 405
      Abstract: This article discusses four fields of study with the potential to revolutionize our understanding and interaction with biological systems: quantum biophotonics, molecular and supramolecular bioelectronics, quantum-based approaches in gaming, and nano-biophotonics. Quantum biophotonics uses photonics, biochemistry, biophysics, and quantum information technologies to study biological systems at the sub-nanoscale level. Molecular and supramolecular bioelectronics aim to develop biosensors for medical diagnosis, environmental monitoring, and food safety by designing materials and devices that interface with biological systems at the molecular level. Quantum-based approaches in gaming improve modeling of complex systems, while nanomedicine enhances disease diagnosis, treatment, and prevention using nanoscale devices and sensors developed with quantum biophotonics. Lastly, nano-biophotonics studies cellular structures and functions with unprecedented resolution.

      Abstract: Driver assistance systems have started becoming a key differentiator in automotive space and all major automotive manufacturers have such systems with various capabilities and stages of implementation. The main building blocks of such systems are similar in nature and one of the major building block is road lane detection. Even though lane detection technology has been around for decades, it is still an ongoing area of research and there are still several improvements and optimizations that are possible. This paper offers an Optimized Dynamic Origin Technique (Optimized DOT) for lane detection. The proposed optimization algorithm of optimized DOT gives better results in performance and accuracy compared to other methods of lane detection. Analysis of proposed optimized DOT with various edge detection techniques, various threshold levels, various sample dataset and various lane detection methods were done and the results are discussed in this paper. The proposed optimized DOT lane detection average processing time increases by 9.21 % when compared to previous Dynamic Origin Technique (DOT) and 59.09 % compared to traditional hough transform.
