Authors: Fałtynowicz Zbigniew
Published: April 2020

Dwudziestego dziewiątego czerwca 1980 roku w leśniczówce Pranie nad Jeziorem Nidzkim otwarto Muzeum Konstantego Ildefonsa Gałczyńskiego. W miejscu tym wybitny poeta spędził z przerwami ostatnie lata życia (1950–1953). Tu napisał swoje najpiękniejsze utwory: poematy "Niobe" i "Wit Stwosz", "Kronikę olsztyńską" i cykl "Pieśni". Przez wiele lat opiekę nad ta placówką muzealną sprawowała córka poety Kira Gałczyńska i jej mąż Janusz Kilański. Od września 1997 roku kustoszami tego miejsca są Jagienka Kass i Wojciech Kass – dyrektor muzeum. Dzięki opracowanemu i konsekwentnie realizowanemu programowi pod nazwą Ośrodek Promienny, Muzeum Konstantego Ildefonsa Gałczyńskiego w Praniu stało się instytucją tętniąca życiem artystycznym, literackim i kulturalnym. Jest znane w kraju z wielu inicjatyw kulturotwórczych. Odbywają się w nim między innymi liczne koncerty, spektakle, spotkania autorskie, wernisaże wystaw. Działalność placówki przyczynia się w znaczący sposób do upowszechniania literatury i muzyki, a także twórczości Konstantego Ildefonsa Gałczyńskiego. Nieustannie też muzeum wzbogaca swoje zbiory o przedmioty związane z autorem "Zaczarowanej dorożki", a także troszczy się w różnych formach o wzbogacanie wiedzy o życiu i twórczości poety, między innymi organizując w roku 2019 konferencję naukową.

Lime salts: origin and control in beet processing
Authors: de Bruijn Jan Maarten
Published: April 2020

Lime salts in the thin juice obtained after juice purification is one of the most important chemical KPI’s (Key Performance Indicator) in beet processing. Too high lime salts content will significantly affect processing costs – particularly energy – due to scaling of heat exchange surfaces thus decreasing heat transfer. In addition, high lime salts are at the origin of turbidity and insoluble solids in white sugar. Therefore, it is of the utmost importance to understand the chemistry behind lime salts in beet processing in order to be able preventing too high lime salts contents in thin juice. This paper will explain the details of the chemistry behind the presence of lime salts. Further, a trouble-shooting guide is included to elucidate the different causes for high lime salts contents and how these causes can be identified, as well as the process measures to reduce the lime salts content in thin juice.
The Hydrophily of Some Lacquers for Electrical Use
Authors: Bors Adriana-Mariana , Caramitu Alina-Ruxandra , Marin Dorian , Lingvay Iosif
Published: April 2020

Through gravimetric determinations, volume resistivity, dielectric spectroscopy, and comparative thermal analysis (TG, DTA and DTG), the interactions between the distilled water and three different types of alkyd-epoxy-melamine, epoxy and polyurethane lacquers were studied. From the experimental determinations it was found that after 700 h of immersion in water at 20 � 2�C the alkyd-epoxy-melamine based lacquer has a maximum water uptake, respectively 1.76%, followed by the epoxy lacquer 1.4% and polyurethane 0.93%. The thermal analysis sugests that because the water retained by the investigated polymers does not change the TG diagrams in the temperature range up to 150 �C, which suggests that the weight increase of the samples during the immersion could be due to some chemical processes between the water and polymer by which the chemistry structure of the polymer changes. Through electrical measurementes one can observe that after the immersion in water (over 700 hours), dielectric loss increases and the volume resistivity (measured in DC) of the investigated lakes decreases, which is explained by the increasing of polar groups (-OH) in the polymer structure. A comparative analysis of the experimental data reveals that in electrical applications the lacquer LS (polyurethane) is superior to the lacquers L-528 (alkyd-epoxy-melamine) and LG (epoxy), because it has no mass losses (structural changes) up to 280�C it has a volume resistivity of about 21 % higher than L-G, and about 300 % higher than L-528, and has water uptake and dielectric loss substantially lower comparing to L-528 and L-G.

Authors: Kiss Imre , Baciu Andrei Mihai , Bordeasu Ilare , Micu Lavinia Madalina
Published: April 2020

The wastes from polyethylene terephthalate (PET) packaging can be turned into armatures for concrete used in the transports infrastructure (roads with rigid concrete structure, pedestrian and concrete pavements and borders), as well as in the construction of safety elements (support walls, bulwark foundations). This experimental research was meant to create dispersed reinforced concrete with armatures from polyethylene waste, originated from the recycling programmes of PET-type packaging. The experimental programme was aimed at constructing some samples of dispersed reinforced concrete from recycled material coming from polyethylene terephthalate (PET) packaging wastes, their testing to the compressive strength and the comparison of results with the characteristics of the standardised samples of concrete (class C30/37). All the reinforcements used in this work to consolidate the dispersed reinforced concrete type were made from a mix of polyethylene terephthalate (PET) packages, of different types and characteristics, which are found daily in supermarkets and which then reach waste. The choice of a mix of polyethylene terephthalate (PET) packaging was chosen in order to render the general recycling of these types of materials as good as possible.
Compressive Strength of Woven and Strand of Recycled Polyethylene Terephthalate (PET) Reinforced Concrete
Authors: Baciu Andrei Mihai , Kiss Imre , Bordeasu Ilare , Micu lavinia Madalina
Published: April 2020

Woven fiber reinforced concrete is a material, which contains various quantities of polymer materials in composition, in addition to the conventional components of an ordinary concrete (mineral binder - cement, aggregates, water and additives). The present work refers to the concrete in which the reinforcement is made of polymeric materials (polyethylene terephthalate), originated from the recycling programs of PET-type packaging. The experimental program was aimed at constructing some samples of woven fiber reinforced concrete from recycled material coming from PET packaging wastes, their testing to the compression demands and the comparison of results with the characteristics of the standardized samples of concrete (class C30/37). Based on a sufficient number of determinations, certain correlations can be established between the compressive strength of the concrete at 28 days depending on the dosage of components (aggregate, binder, and reinforcement), water / cement ratio, reinforcement volume, etc., essential parameters from a compositional point of view. These correlations, customized by cement type and strength class, are very important to determine - with approximation - to what dosage of components (aggregate, binder, reinforcement) the respective level of compressive strength of concrete is obtained.

This study aims to find the most effective method in terms of clinical working time when applying fibreglass splints in the lower frontal group, depending on the type of composite material used. We have selected a group of 30 patients, aged between 50 and 70, with an average age of 57, in the interval March 2016 - June2017. These patients received immobilisations as part of their periodontal treatment, using a system consisting of fibreglass and three different types of composites. The shortest work time was obtained when using the Grandioso heavy flow composite, the next closest time being obtained with Gaenial flow universal. Our study indicated that the highly viscous flow composite resins offers the shortest clinical working time out of all tested materials.

Published: April 2020

The red deer is a main game species in Bulgaria, as well as in large parts of Europe. However, its behaviour has not been studied in depth on a local scale, especially on the Balkans. This study presents the first GPS telemetry data for red deer in Bulgaria –in the Central and Eastern Balkan Mountains, the Rhodopi Mountains and the lowlands of North-eastern Bulgaria. 18 individuals (2 subadult stags, 12 adult stags and 4 adult hinds) were tracked, accumulating a total of 1159 (for males) and 1464 (for females) GPS fixes. In spite of the pronounced individual differences, all stags were more mobile (average step length/12 h = 857 m) and had larger home ranges (average HR = 7393 ha) than hinds (average HR = 2085 ha, average step length/12 h = 448 m). Three of the individuals (1 hind and 2 stags) dispersed, forming two distinct home ranges. The results from this study outline the need for detailed studies on the behavior of the species, as a vital part of its management and conservation.

Elliptic Curve Scalar Point Multiplication Algorithm Using Radix-4 Booth’s Algorithm
Authors: Moon Sangook
Published: April 2020

The main back-bone operation in elliptic curve cryptosystems is scalar point multiplication. The most frequently used method implementing the scalar point multiplication, which is performed in the topmost level of GF multiplication and GF division, has been the double-and-add algorithm, which is being recently challenged by NAF (Non-Adjacent Format) algorithm. In this paper, we propose a more efficient and novel approach of a scalar multiplication method than the double-and-add by applying redundant recoding which originates from the radix-4 modified Booth’s algorithm. We call the novel algorithm quad-and-add. After deriving the algorithm, we created a new GF operation, named point quadruple, and verified with calculations of a real-world application to utilize it. Derived numerical expressions were verified using both C programs and HDL (Hardware Description Language). Proposed method of elliptic curve scalar point multiplication can be utilized in many elliptic curve security applications for handling efficient and fast calculations.

This paper describes a compact 32-bit architecture developed for the Rijndael ciphering/deciphering system. The implementation is complied with NIST Advanced Encryption Standard (AES). The design processes any 128-bit block data with 128-bit key. For the compact hardware, the field inversion circuit and the key scheduling circuits are shared by both the encryption and decryption process. The on-the-fly KeyScheduling implementation offers fast processing speed but with core size trade-off. According to the evaluation made on the targeted FPGA, the design can offer the throughput of 768 mbps at 264 MHz clock speed.
50 Years of Progress in Speech and Speaker Recognition Research
Authors: Furui Sadaoki
Published: April 2020

Research in automatic speech and speaker recognition has now spanned five decades. This paper surveys the major themes and advances made in the past fifty years of research so as to provide a technological perspective and an appreciation of the fundamental progress that has been accomplished in this important area of speech communication. Although many techniques have been developed, many challenges have yet to be overcome before we can achieve the ultimate goal of creating machines that can communicate naturally with people. Such a machine needs to be able to deliver a satisfactory performance under a broad range of operating conditions. A much greater understanding of the human speech process is required before automatic speech and speaker recognition systems can approach human performance.
Metamorphic Testing Using Geometric Interrogation Technique and Its Application
Authors: Sim K.Y. , Pao W.K.S. , Lin C.
Published: April 2020

Usual techniques used in the automatic test case generation and executions assume that a complete oracle will be available during the testing process. However, in some numerical programs this assumption is not valid because the oracle in form of analytical solution is either not available or too difficult to obtain. To overcome this problem, metamorphic testing proposes to generate follow-up test cases to check important properties of the output function. We study the intrinsic properties of Medial Axes for casting applications. Even though Medial Axes is a geometric function that is independent from the output function of casting simulation, we propose to use its intrinsic properties for metamorphic testing of casting simulation to alleviate the oracle problem.

Published: April 2020

In this paper, it is shown how to adapt certain matrix transformation to create a novel asymmetric block encryption scheme. The proposed scheme is especially useful for encryption of large amounts of data, such as digital images. First, a pair of keys are given by using matrix transformation; Second, the image is encrypted using private key in its transformation domain; Finally the receiver uses the public key to decrypt the encrypted messages. This scheme satisfies the characters of convenient realization, less computation complexity and good security.
Modelling, Detection and Exploitation of Lexical Functions for Analysis
Authors: Schwab Didier , Lafourcade Mathieu
Published: April 2020

Lexical functions (LF) model relations between terms in the lexicon. These relations can be knowledge about the world (Napoleon was an emperor) or knowledge about the language ( is synonym of ). In this article, we show that LF instanciation in texts is useful both for semantic analysis (for example, resolution of lexical ambiguities or prepositional attachment and synthesis, i.e. natural language generation. We describe the architecture of a Semantic Lexical Base and the way how LFs are modeled, detected and used. More precisely, we show how each LF is modelled using thematic (conceptual vectors) and lexical (materialised relations between database objects) information and how we exploit the results in the base. We also describe how these functions allow the database to be explored continuously rather than in a discrete way.

Effects of Path Visibility on Urban MIMO Systems
Authors: Hemrungrote Sirichai , Hori Toshikazu , Fujimoto Mitoshi , Nishimori Kentaro
Published: April 2020

Multiple-Input Multiple-Output (MIMO) wireless communication technology is expected to improve the channel capacity over the limited bandwidth of existing networks. Since urban MIMO systems have complex propagation characteristics, the channel capacity cannot be estimated using a simple method. Hence, we introduce channel capacity characteristics to urban MIMO systems by using a combination of imaging and ray-launching methods as a ray-tracing scheme. A simulation based on these methods with variable parameters can reproducibly estimate various urban propagation characteristics and discriminate the effects of the urban model and antenna configurations. The characteristics of the Signal-to-Noise Ratio (SNR), the channel capacity, the spatial correlation, as well as the path visibility are then determined from the results of the simulation. The parameter called path visibility introduced in our previous study is considered again herein. We clarify that only this single parameter can be used to determine the channel capacity characteristics in urban MIMO scenarios. This parameter also provides guidance in determining the appropriate range for the base station (BS) height.
Adaptive Forgetting-factor RLS-based Initialisation Per-tone Equalisation in Discrete Multitone Systems
Authors: Sitjongsataporn Suchada
Published: April 2020

An adaptive forgetting-factor inverse square-root recursive least squares (AF-iQRRLS) with inverse of correlation matrix updating is presented for per-tone equalisation in discrete multitone-based systems. The proposed inverse covariance update of the square-root covariance Kalman filter is introduced to prepare for the signal flow graph (SFG). This reduced derivation of adaptive inverse square-root recursive least squares algorithm can modify via SFG. In order to reduce the computational complexity, the forgetting-factor parameter for each group called per-group forgettingfactor (PGFF) approach based on AF-iQRRLS algorithm is introduced. The forgetting-factor from the middle of each group is selected as a representative in order to find an optimal forgetting-factor parameter by using AF-iQRRLS algorithm. After convergence, it is fixed for remaining tones of whole group. Simulation results reveal that the trajectories of modified PGFF of the proposed algorithm for each individual tone can converge to their own equilibria. Moreover, the performance of the proposed algorithms are improved as compared with the existing algorithm.
Signal and Image Processing in the Encrypted Domain
Authors: Kiya Hitoshi , Fujiyoshi Masaaki
Published: April 2020

This paper describes signal processing in the encrypteddomain, i.e., that after encryption but before decryption. In this framework, signal processing operations can be directly applied to encrypted signals without decrypting of encrypted signals, whereas the ordinary framework encrypts signals for transmission and/or storing but it decrypts them before signal processing operations are applied to. The described framework befits contemporary cloud computing in which not only transmission but also storing and processing are done in the public Internet. Addition to brief survey, two tangible application scenarios are also demonstrated in this paper where a new signal processing algorithm is introduced each.

Published: April 2020

This paper presents the design and analysis of a floating-point arithmetic accelerator in compliance with the IEEE standard single precision floatingpoint format. The accelerator can be used to extend a general-purpose processor such as Motorola MC6820, where floating-point execution units are unembedded by default. It implements standard and non-standard mathematic functions, addition/subtraction, multiplication, Product-of-Sum and Sumof- Product through a micro-instruction set supported by both single and multi-processors systems. The architecture of the unit is based on an instruction pipeline which can simultaneously fetch and execute an instruction within one clock cycle. The non-standard operations such as Product-of-Sum and Sum-of-Product are introduced to compute threeinput operands. The algorithm complexity and hardware critical delay are determined for each operator. The synthesis results of the accelerator on a Xilinx FPGA Virtex 5 xc5vlx110t-3ff-1136 and on Faraday 130-nm Silicon technology report that the design respectively achieves 200 MHz and 1 GHz.
A Cross Video-MAC Layer Approach for Generating Adaptive FMO Map
Authors: Huu Vu Tien , Aramvith Supavadee
Published: April 2020

Recent researches in video transmission over heterogeneous networks move toward cross-layer design to realize the optimal video quality. In this work, we investigate the cross layer approach between H.264 video coding layer and IEEE 802.11e Medium Access Control (MAC) layer on the issues of how to improve error resiliency of H.264 video using Flexible Macroblock Ordering (FMO), and how to reduce packet dropping rate at MAC layer. We propose an adaptive FMO map generation to separate high and low important macroblocks to different priority queues based on the overflow state of MAC layer queues. The arrival rate of packets to queues is thus changed to reduce the queue overflow and to decrease of the packet droppingrates at queues. Experimental results show that using the proposed scheme can reduce the packet drop rate at the queues resulting in the reduction of packet loss rate and the improvement of the average PSNR.
Complexity Reduction of Modied Per-Survivor Iterative Timing Recovery for Partial Response Channels
Authors: Warisarn Chanon , Kovintavewat Piya , Supnithi Pornchai
Published: April 2020

The problem of timing recovery operating at low signal-to-noise ratio has been recently solved by a modified per-survivor iterative timing recovery (MPS-ITR) proposed in [1], which jointly performs timing recovery, equalization, and error-correction decoding. In practice, this scheme exploits a splitpreamble strategy in conjunction with a per-survivor soft-output Viterbi algorithm equalizer to make it more robust against severe timing jitters or cycle slips. Although the MPS-ITR outperforms existing iterative timing recovery schemes [1], its complexity is extremely high. Therefore, this paper proposes a reduced-complexity MPS-ITR scheme (denoted as MPS-ITR-M) to make it more implementable in reallife applications. This is achieved by applying the M-algorithm [2] to the MPS-ITR. Numerical results show that at low-to-moderate complexity, the MPSITR- M performs better than other schemes.
Empirical Modelling for exploring the factors contributing to disability severity from road traffic accidents in Thailand
Authors: Rungrattanaubol Jaratsri , Na-udom Anamai , Harfield Antony
Published: April 2020

This paper introduces a computer-based model for predicting the severity of injuries in road traffic accidents. Using accident data from surveys at hospitals in Thailand, standard data mining techniques were applied to train and test a multilayer perceptron neural network. The resulting neural network specification was loaded into an interactive environment called EDEN that enables further exploration of the computer-based model. Although the model can be used for the classification of accident data in terms of injury severity (in a similar way to other data mining tools), the EDEN tool enables deeper exploration of the underlying factors that might affect injury severity in road traffic accidents. The aim of this paper is to describe the development of the computer-based model and to demonstrate the potential of EDEN as an interactive tool for knowledge discovery.
VLSI Implementation With Double Cipher and Media Processing for Ad-Hoc Network
Authors: Fukase Masa-aki
Published: April 2020

Ubiquitous network is really one of remarkable trends of next generation information and communication technologies. However, the rapid increase of ubiquitous technologies has given rise to serious concerns about security issues which are getting worse, especially in the case of ad-hoc network because it is resource constrained. Both transience and secureness are characteristic features of ad-hoc network. In order to provide a sophisticated processor accompanied with such characteristics, we have so far developed HCgorilla. This is a ubiquitous processor that unifies basic aspects of PC processors, mobile processors, Java CPUs, cryptography processors, etc. The unification of these processors has shown effectiveness to achieve not only power and chip area saving but also secureness for ubiquitous environment. The secureness provided by HCgorilla is temporal with practically enough cipher strength and without relying on permanent network infrastructure. This is really one of qualitative conditions required for ad-hoc networks. Considering the ever growing ubiquitous network, the target of this study is the total optimum design of HCgorilla chips with particular emphasis on small resource and secure implementation. The improved version, HCgorilla.7 is implemented in a CMOS standard cell chip. Specific features of HCgorilla.7 are described regarding occupied area, power consumption, throughput, and cipher strength. Judging from these results, HCgorilla is one of most profitable candidates for the next generation ubiquitous environment.
A Design Method for a Robust Stabilizing Multi-Period Repetitive Control System for Multiple-Input/Multiple-Output Plants with Specied Input-Output Frequency Characteristic Using the Parameterization
Authors: Chen Zhongxiang , Sakanushi Tatsuya , Yamada Kou , Tohnai Satoshi , Zhao Yun
Published: April 2020

The multi-period repetitive control system is a type of servomechanism for a periodic reference input. Recently, the parameterization of all robust stabilizing multi-period repetitive controllers for multipleinput/ multiple-output plants with uncertainty was obtained by Chen et al. However, using their method, it is complex to specify the low-pass filter in the internal model for the periodic reference input of which the role is to specify the input-output frequency characteristic. Because, the low-pass filter is related to four free parameters in the parameterization proposed by Chen et al. Chen et al. examined the parameterization of all robust stabilizing multi-period repetitive controllers for multiple-input/multiple-output plants with specified input-output frequency characteristic such that the input-output frequency characteristic can be specified beforehand. However, they omitted complete proof on account of space limitations. This paper gives the complete proof and demonstrates the effectiveness of the parameterization. The control characteristics of the system are presented, along with a design procedure for a robust stabilizing multi-period repetitive controller with specified input-output frequency characteristic. A numericalexample is presented to illustrate the effectiveness of the proposed method.

Published: April 2020

The modified repetitive control system is a type of servomechanism for a periodic reference input. When modified repetitive control design methods are applied to real systems, the influence of uncertainties in the plant must be considered. In some cases, uncertainties in the plant make the modified repetitive control system unstable, even though the controller was designed to stabilize the nominal plant. Recently, the parameterization of all robust stabilizing modified repetitive controllers was obtained by Yamada et al. In addition, Yamada et al. proposed the parameterization of all robust stabilizing modified repetitive controllers for time-delay plants. However, no paper has proposed the parameterization of all robust stabilizing modified repetitive controllers for multiple-input/multiple-output time-delay plants. In this paper, we expand the result by Yamada et al. and propose the parameterization of all robust stabilizing modified repetitive controllers for multipleinput/multiple-output time-delay plants.
Blind Scheme with Histogram Peak Estimation for Histogram Modication-Based Lossless Information Embedding
Authors: Fujiyoshi Masaaki
Published: April 2020

In this paper, a simple scheme for histogram modification-based lossless information embedding (HM-LIE) is proposed. The proposed scheme is free from memorizing side information, i.e., blind. A HMLIE scheme modifies particular pixel values in an image in order to embed information in it on the basis of its histogram, i.e., tonal distribution. The scheme recovers the original image as well as extracts embedded information from a distorted image conveying embedded information. Most HM-LIE schemes should memorize a set of image-dependent side information per image. The proposed scheme does not have to memorize such information to avoid costly identification of the distorted image carrying embedded information because of the introduction of two mechanisms. One is estimating side information on the basis of a simple statistic, and the other is concealing not only main information but also a part of the side information in the image. These approaches make the proposed scheme superior to the conventional blind schemes in terms of the quality of imagesconveying embedded information.

Thin film preparation of silicon nanocrystals embedded in silicon oxide by sol-gel method
Authors: Fangsuwannarak Thipwan , Khunchana Kanika
Published: April 2020

In this paper, nano silicon powders were prepared by the grinding technique and subsequently mixed in sol-gel of Tetraethylorthosilicate and ethanol solution. The silicon dioxide films synthesized from the sol-gel solution were preliminary studied in the term of the optical property as a refractive index (n) by varying the aging time and annealing temperatures. By using a Fourier transform infrared spectroscopy technique, the obtained x-composition values of the SiOx films were extended from 1.67 to 1.98 with a decreasing time of the aged sol-gels. In addition, the lower x-composition value can be controlled by increasing the annealing temperatures from 60◦C to 500◦C. The prepared films from the precursor of nano-silicon powder suspension were characterized by photoemission spectroscopy and Raman spectroscopy in order to obtain more understanding of the chemical composition and silicon nano-crystallite quality, respectively. Presenting the spectra broadening and the frequency downshifting from 521 cm−1 was caused by the quantum size effect.

Published: April 2020

This paper presents our experimental work on two aspects of sentiment analysis. First, we evaluate the performance of different machine learning as well as lexicon based methods for sentiment analysis of texts obtained from variety of sources. Our performance evaluation results are on six different datasets of different kinds, including movie reviews, blog posts and twitter feeds. To the best of our knowledge no such work on comprehensive evaluative account involving different techniques on variety of datasets have been reported earlier. The second major work that we report here is about the heuristic based scheme that we devised for aspect-level sentiment profile generation of movies. Our algorithmic formulation parses the user reviews for a movie and generates a sentiment polarity profile of the movie based on opinion expressed on various aspects in the user reviews. The results obtained for the aspect-level computation are also compared with the corresponding results obtained from the document-level approach. In summary, the paper makes two important contributions: (a) it presents a detailed evaluative account of both supervised and unsupervised algorithmic formulations on six datasets of different varieties, and (b) it proposes a new heuristic based aspect-level sentiment computation approach for movie reviews, which results in a more focused and useful sentiment profile for the movies.

Published: April 2020

This paper addresses two NP-hard and strongly related problems in production planning of flexible manufacturing system (FMS), part type selection problem and machine loading problem. Various flexibilities such as alternative machines, tools, and production plans are considered. Real coded genetic algorithms (RCGA) that uses an array of real numbers as chromosome representation is developed to handle these flexibilities. Hybridizing with variable neighbourhood search (VNS) is performed to improve the power of the RCGA exploring and exploiting the large search space of the problems. The effectiveness of this hybrid genetic algorithm (HGA) is tested using several test bed problems. The HGA improves the FMS effectiveness by considering two objectives, maximizing system throughput and minimizing system unbalance. The resulted objective values are compared to the optimum values produced by branch-and-bound method. The experiments show that the proposed RCGA could reach near optimum solution and the hybridization can improve the performance of the RCGA.
Agent Aided Routing for Faster and Efficient Spreading of Messages in Delay Tolerant Networks
Authors: Asif Iqbal Shahid Md. , Chowdhury Alok Kumar , Akhter Amina
Published: April 2020

Routing schemes in Delay Tolerant Networks depend on the intermediate nodes to carry messages till the forwarding of the messages to other nodes or delivery of the messages to their destinations. Thus, efficient and faster spreading of messages is essential to reduce the delay of sending a message from source to destination. In this work, we aim to design a new agent aided routing scheme in Delay Tolerant Networks to avoid large message delivery delay. Here, the source of a message is permitted to create unlimited copies of a message and distribute these copies to agents. Agents acting as the representative of the sources receive messages from the sources based on their node visited list and delivery predictability. After that, the agents forward the copies to the other intermediate nodes or deliver the message directly to the destination. Thus, the agents help in faster and efficient dissemination of a message in the network which helps in reducing message delivery delay. Besides, we compare our scheme with that of other schemes in different network scenarios through simulations. Simulation results show that our agent based routing scheme performs better than that of others in terms of Delivery Ratio, Delay and Communication Overhead.
Peak-to-Average Power Ratio Reduction Method for OFDM Signal by Permutation of Subcarriers
Authors: Boonsrimuang Pornpawit , Limwattanacha Kanchana , Boonsrimuang Pisit , Kobayashi Hideo
Published: April 2020

Many PAPR reduction methods for OFDM time domain signal have been proposed up to today, all of which can be classified into two kinds of methods as the distortion and distortion-less methods. The most of distortion-less methods show better PAPR performance without degradation of BER performance. However the distortion-less methods are usually required to control the transmission data information so as to minimize the PAPR performance at the transmitter. From this fact, the distortion-less methods are required to inform the controlled information as the side information to the receiver for the correct demodulation of data information. The side information is usually informed to the receiver with the higher signal quality by using the separate channel or the embedded in the data information which would lead the degradation of transmission efficiency and the increase of hardware complexity of transmitter and receiver.
This paper proposes a novel distortion-less PAPR reduction method which employs the permutation of subcarriers in the frequency domain. The feature of proposed method is to achieve the better PAPR performance with a very few embedded side information for the correct demodulation of data information at the receiver. This paper presents various computer simulation results to verify the effectiveness of proposed method as comparing with the conventional OFDM method in the non-linear channel.
Hardware Evaluations of Simple Radio Positioning System Based on Direct Sequence Spread Spectrum
Authors: Watanabe Shinichi , Okada Minoru
Published: April 2020

This paper proposes a simple positioning scheme without huge computational cost. The proposed scheme employs a three-element loop array for the transmitter. A Direct-Sequence Spread Spectrum (DS/SS) sequence is transmitted at a frequency of Low Frequency (LF) band. We evaluate location determination error rate by using a computer simulator and theoretical analysis. The theoretical analysis agrees with the simulation result. The difference is at most 1.3 dB at error rate of 10−5. Computer simulation result shows that the proposed technique can identify the region of 2 by 3 meters at the region determination error rate of 10−2. In order to show the hardware complexity requirement for implementing the proposed receiver, the impact of bit width for ADC (Analog-to-Digital Converter), and digital signal processing block to the error rate performance is evaluated by computer simulation. Computer simulation shows that the proposed scheme can be constructed by 2-bit ADC and 5-bit integrate and dump filter.
An Evaluation of Significant Lightness Difference Effective Term for CIEDE2000 Comparative Image Colour Pixels
Authors: Homnan Bongkarn , Benjapolakul Watit
Published: April 2020

As CIEDE2000 standard has developed the colour difference formula, the colour difference formula of compared colours in similar colour space has been evaluated and emphasized in this paper. The lightness difference effective term has been distinctively separated from the small informative colourdifference of CIEDE2000. In addition, the power of the lightness difference effective term can clearly magnify the lightness difference which illustrated categorized surfaces of the lightness difference effective term for total colour differences in the CIEDE2000 standard. All projected four categories are classified by compared image colour pixels based on the colour space’s three forward transform functions of the lightness of the colour, the chroma between red/magenta and green, and the chroma between yellow and blue. Results show that the lightness difference effective term gives mainly three different surfaces in four categories. Furthermore, in first category, the most two maximum statistical frequencies can be expressed with the left side along with the right side of the probability mass function of the lightness difference effective term; in third category, the obvious maximum statistical frequency can be expressed with only the left side of the probability mass function; and in second and fourth categories, the maximum statistical frequency can be expressed most absolutely with the left side of the probability mass function.
