Published: July 2021

Morphology is the most visible and distinct character of plant organs and is accepted as one of the most important tools for plant biologists, plant breeders and growers. A number of methods based on plant morphology are applied to discriminate in particular close cultivars. In this study, image processing analysis was used on 20 grape cultivars (“Amasya beyazı“, “Antep karası“, “Bahçeli karası”, “Çavuş“, “Cevşen“, “Crimson“, “Dimrit“, “Erenköy beyazı“, “Hafızali“, “Karaşabi“, “Kırmızı“, “İzabella (Isabella) “, “Morşabi“, “Müşgüle“, “Nuniya“, “Royal“, “Sultani çekirdeksiz (Sultanina)“, “Yalova incisi“, “Yerli beyazv“, “Yuvarlak çekirdeksiz“) to classify them. According to image processing analysis, the longest and the greatest projected area values were observed in “Antep karası“ cultivar. The “Sultani çekirdeksiz“ cultivar had the least geometric mean diameter. The greatest sphericity ratios were observed in “Yerli beyaz“, “Erenköy beyazı“ and “Amasya beyazı“ cultivars. According to principal component analysis, dimensional attributes were identified as the most significant source of variation discriminant grape cultivars from each other. Morphological differences between the cultivars were explained by sphericity and elongation variables. According to elliptic Fourier analysis (EFA) results, grape morphology largely looks like ellipse and sphere. However, there are some cultivars that look similar to a water drop. The cultivars with similar morphology were identified by a pair-wise comparison test conducted with the use of linear discriminant analysis, and they were presented in a scatter plot. According to cluster analysis, present grape cultivars were classified into seven sub-groups, which indicated great diversity.

Published: July 2021

Siberian wildrye (Elymus sibiricus L.) is a salt-tolerant, high-quality forage grass that plays an important role in forage production and ecological restoration. Abscisic acid (ABA)-insensitive 5 (ABI5) is essential for the normal functioning of the ABA signal pathway. However, the role of ABI5 from Siberian wildrye under salt stress remains unclear. Here, we evaluated the role of Elymus sibiricus L. abscisic acid-insensitive 5 (EsABI5) in the ABA-dependent regulation of the response of Siberian wildrye to salt stress. The open reading frame length of EsABI5 isolated from Siberian wildrye was 1170 bp, and it encoded a 389 amino acid protein, which was localized to the nucleus, with obvious coiled coil areas. EsABI5 had high homology, with ABI5 proteins from Hordeum vulgare, Triticum monococcum, Triticum aestivum, and Aegilops tauschii. The conserved domains of EsABI5 belonged to the basic leucine zipper domain superfamily. EsABI5 had 10 functional interaction proteins with credibility greater than 0.7. EsABI5 expression was upregulated in roots and leaves under NaCl stress and was upregulated in leaves and downregulated in roots under ABA treatment. Notably, tobacco plants overexpressing the EsABI5 were more sensitive to salt stress, as confirmed by the determining of related physiological indicators. EsABI5 expression affected the ABA and mitogen-activated protein kinase pathways. Therefore, EsABI5 is involved in antisalt responses in these pathways and plays a negative regulatory role during salt stress.

Published: July 2021

Acacia macrostachya is used in Burkina Faso folk medicine for the treatment of inflammation and cancer. The purpose of this study was to evaluate the antioxidant and cytotoxic effects of this plant. The cytotoxic effects of root (dichloromethane B1 and methanol B2) and stem (dichloromethane B3 and methanol B4) bark extracts of A. macrostachya were assessed on chronic K562 and acute U937 myeloid leukemia cancer cells using trypan blue, Hoechst, and MitoTracker Red staining methods. The antioxidant content of extracts was evaluated using DPPH (2,2-diphenyl-1-picryl-hydrazyl) and FRAP (ferric reducing antioxidant power) methods. The root bark extracts B1 and B2 of A. macrostachya demonstrated higher cytotoxicity with IC50 values in a low µg/mL range on both U937 and K562 cells, while the stem bark B4 extract selectively affected U937 cells. Overall, healthy proliferating peripheral blood mononuclear cells (pPBMCs) were not or barely impacted in the range of concentrations cytotoxic to cancer cells. In addition, A. macrostachya exhibited significant antioxidant content with 646.06 and 428.08 µg ET/mg of extract for the B4 and B2 extracts, respectively. Phytochemical screening showed the presence of flavonoids, tannins, alkaloids, and terpenoids/steroids. The results of this study highlight the interest of A. macrostachya extracts for the isolation of anticancer molecules.
Dextran: Sources, Structures, and Properties
Authors: Díaz-Montes Elsa
Published: July 2021

Dextran is an exopolysaccharide (EPS) synthesized by lactic acid bacteria (LAB) or their enzymes in the presence of sucrose. Dextran is composed of a linear chain of d-glucoses linked by α-(1→6) bonds, with possible branches of d-glucoses linked by α-(1→4), α-(1→3), or α-(1→2) bonds, which can be low (<40 kDa) or high molecular weight (>40 kDa). The characteristics of dextran in terms of molecular weight and branches depend on the producing strain, so there is a great variety in its properties. Dextran has commercial interest because its solubility, viscosity, and thermal and rheological properties allow it to be used in food, pharmaceutical, and research areas. The aim of this review article is to compile the latest research (in the past decade) using LAB to synthesize high or low molecular weight dextran. In addition, studies using modified enzymes to produce dextran with specific structural characteristics (molecular weights and branches) are addressed. On the other hand, special attention is paid to LAB extracted from unconventional sources to expose their capacities as dextran producers and their possible application to compete with the only commercial strain (Leuconostoc mesenteroides NRRL B512).
Non-Gaussianity of Four-Photon Superpositions of Fock States
Authors: de Freitas Miguel Citeli , Dodonov Viktor V.
Published: July 2021

We study two families of four-photon superpositions of the Fock states: even vacuum squeezed states (EVSS) and orthogonal-even coherent states (OECS). These families are distinguished due to several properties: for certain values of parameters, they give the fourth-order uncertainty products close to the known minimal value (which is lower than for the Gaussian states); they have equal dimensionless values of the second- and fouth-order moments of the coordinate and momentum for all values of parameters; they possess zero covariances for all values of parameters. Since these states are obviously non-Gaussian, we consider them as good candidates to compare several different measures of non-Gaussianity proposed by different authors for the past fifteen years. The reference Gaussian states in all examples are thermal states dependent on a single parameter (an effective temperature or the coordinate variance). We analyze the measures based on the normalized Hilbert–Schmidt distance and the relative entropy (introduced by Genoni–Paris–Banaszek), the fidelity measure (Ghiu–Marian–Marian) and its logarithmic analog (Baek–Nha), as well as the Mandilara–Karpov–Cerf “Gaussianity parameter”. These measures are compared with the kurtosis of the coordinate probability density and with the non-Gaussian behavior of the Wigner function.
SAR ATR for Limited Training Data Using DS-AE Network
Authors: Park Ji-Hoon , Seo Seung-Mo , Yoo Ji-Hee
Published: July 2021

Although automatic target recognition (ATR) with synthetic aperture radar (SAR) images has been one of the most important research topics, there is an inherent problem of performance degradation when the number of labeled SAR target images for training a classifier is limited. To address this problem, this article proposes a double squeeze-adaptive excitation (DS-AE) network where new channel attention modules are inserted into the convolutional neural network (CNN) with a modified ResNet18 architecture. Based on the squeeze-excitation (SE) network that employs a representative channel attention mechanism, the squeeze operation of the DS-AE network is carried out by additional fully connected layers to prevent drastic loss in the original channel information. Then, the subsequent excitation operation is performed by a new activation function, called the parametric sigmoid, to improve the adaptivity of selective emphasis of the useful channel information. Using the public SAR target dataset, the recognition rates from different network structures are compared by reducing the number of training images. The analysis results and performance comparison demonstrate that the DS-AE network showed much more improved SAR target recognition performances for small training datasets in relation to the CNN without channel attention modules and with the conventional SE channel attention modules.
Development of a Self-Powered Piezo-Resistive Smart Insole Equipped with Low-Power BLE Connectivity for Remote Gait Monitoring

Published: July 2021

The evolution of low power electronics and the availability of new smart materials are opening new frontiers to develop wearable systems for medical applications, lifestyle monitoring, and performance detection. This paper presents the development and realization of a novel smart insole for monitoring the plantar pressure distribution and gait parameters; indeed, it includes a piezoresistive sensing matrix based on a Velostat layer for transducing applied pressure into an electric signal. At first, an accurate and complete characterization of Velostat-based pressure sensors is reported as a function of sizes, support material, and pressure trend. The realization and testing of a low-cost and reliable piezoresistive sensing matrix based on a sandwich structure are discussed. This last is interfaced with a low power conditioning and processing section based on an Arduino Lilypad board and an analog multiplexer for acquiring the pressure data. The insole includes a 3-axis capacitive accelerometer for detecting the gait parameters (swing time and stance phase time) featuring the walking. A Bluetooth Low Energy (BLE) 5.0 module is included for transmitting in real-time the acquired data toward a PC, tablet or smartphone, for displaying and processing them using a custom Processing® application. Moreover, the smart insole is equipped with a piezoelectric harvesting section for scavenging energy from walking. The onfield tests indicate that for a walking speed higher than 1 ms−1, the device’s power requirements (i.e., P¯=5.84 mW) was fulfilled. However, more than 9 days of autonomy are guaranteed by the integrated 380-mAh Lipo battery in the total absence of energy contributions from the harvesting section.
Static and Dynamic Verification of Space Systems Using Asynchronous Observer Agents
Authors: Daszczuk Wiktor B.
Published: July 2021

Formal verification of distributed systems is essential, especially in mission-critical systems that cannot be restarted. Such are space systems in which satellites read sensor values and autonomously make actuator decisions based on them, and ground services only set general patterns of behavior. The verification formalism should correspond to the essential characteristics of a distributed system, such as node autonomy and asynchrony of actions and communication, as in our Integrated Model of Distributed Systems (IMDS). It is also crucial that the formalism allows for finding partial deadlocks and checking partial termination, where only a subset of the system nodes is involved while the rest can perform their own tasks at the same time. This article presents the idea of using monitoring agents—observers prepared in the IMDS formalism. Observers check the state of individual system components by polling, allowing verification without knowing the global state of the system. Such an agent is an ideal prototype of a runtime observer that checks if the actual operation of the system corresponds to a design that has previously been proven correct.
On the Improvement of Eye Tracking-Based Cognitive Workload Estimation Using Aggregation Functions
Authors: Kaczorowska Monika , Karczmarek Paweł , Plechawska-Wójcik Małgorzata , Tokovarov Mikhail
Published: July 2021

Cognitive workload, being a quantitative measure of mental effort, draws significant interest of researchers, as it allows to monitor the state of mental fatigue. Estimation of cognitive workload becomes especially important for job positions requiring outstanding engagement and responsibility, e.g., air-traffic dispatchers, pilots, car or train drivers. Cognitive workload estimation finds its applications also in the field of education material preparation. It allows to monitor the difficulty degree for specific tasks enabling to adjust the level of education materials to typical abilities of students. In this study, we present the results of research conducted with the goal of examining the influence of various fuzzy or non-fuzzy aggregation functions upon the quality of cognitive workload estimation. Various classic machine learning models were successfully applied to the problem. The results of extensive in-depth experiments with over 2000 aggregation operators shows the applicability of the approach based on the aggregation functions. Moreover, the approach based on aggregation process allows for further improvement of classification results. A wide range of aggregation functions is considered and the results suggest that the combination of classical machine learning models and aggregation methods allows to achieve high quality of cognitive workload level recognition preserving low computational cost.
Ultra-Highly Sensitive Ammonia Detection Based on Light-Induced Thermoelastic Spectroscopy
Authors: Mi Yao , Ma Yufei
Published: July 2021

This invited paper demonstrated an ultra-highly sensitive ammonia (NH3) sensor based on the light-induced thermoelastic spectroscopy (LITES) technique for the first time. A quartz tuning fork (QTF) with a resonance frequency of 32.768 kHz was employed as a detector. A fiber-coupled, continuous wave (CW), distributed feedback (DFB) diode laser emitting at 1530.33 nm was chosen as the excitation source. Wavelength modulation spectroscopy (WMS) and second-harmonic (2f) detection techniques were applied to reduce the background noise. In a one scan period, a 2f signal of the two absorption lines located at 6534.6 cm−1 and 6533.4 cm−1 were acquired simultaneously. The 2f signal amplitude at the two absorption lines was proved to be proportional to the concentration, respectively, by changing the concentration of NH3 in the analyte. The calculated R-square values of the linear fit are equal to ~0.99. The wavelength modulation depth was optimized to be 13.38 mA, and a minimum detection limit (MDL) of ~5.85 ppm was achieved for the reported NH3 sensor.
Significant Geo-Social Group Discovery over Location-Based Social Network
Authors: Li Wei , Zlatanova Sisi
Published: July 2021

Geo-social community detection over location-based social networks combining both location and social factors to generate useful computational results has attracted increasing interest from both industrial and academic communities. In this paper, we formulate a novel community model, termed geo-social group (GSG), to enforce both spatial and social factors to generate significant computational patterns and to investigate the problem of community detection over location-based social networks. Specifically, GSG detection aims to extract all group-venue clusters, where users are similar to each other in the same group and they are located in a minimum covering circle (MCC) for which the radius is no greater than a distance threshold γ. Then, we present a GSGD algorithm following a three-step paradigm to enumerate all qualified GSGs in a large network. We propose effective optimization techniques to efficiently enumerate all communities in a network. Furthermore, we extend a significant GSG detection problem to top-k geo-social group (TkGSG) mining. Rather than extracting all qualified GSGs in a network, TkGSG aims to return k feasibility groups to guarantee the diversity. We prove the hardness of computing the TkGSGs. Nevertheless, we propose the effective greedy approach with a guaranteed approximation ratio of 1−1/e. Extensive empirical studies on real and synthetic networks show the superiority of our algorithm when compared with existing methods and demonstrate the effectiveness of our new community model and the efficiency of our optimization techniques.
The Quadrature Method: A Novel Dipole Localisation Algorithm for Artificial Lateral Lines Compared to State of the Art
Authors: Bot Daniël M. , Wolf Ben J. , van Netten Sietse M.
Published: July 2021

The lateral line organ of fish has inspired engineers to develop flow sensor arrays—dubbed artificial lateral lines (ALLs)—capable of detecting near-field hydrodynamic events for obstacle avoidance and object detection. In this paper, we present a comprehensive review and comparison of ten localisation algorithms for ALLs. Differences in the studied domain, sensor sensitivity axes, and available data prevent a fair comparison between these algorithms from their original works. We compare them with our novel quadrature method (QM), which is based on a geometric property specific to 2D-sensitive ALLs. We show how the area in which each algorithm can accurately determine the position and orientation of a simulated dipole source is affected by (1) the amount of training and optimisation data, and (2) the sensitivity axes of the sensors. Overall, we find that each algorithm benefits from 2D-sensitive sensors, with alternating sensitivity axes as the second-best configuration. From the machine learning approaches, an MLP required an impractically large training set to approach the optimisation-based algorithms’ performance. Regardless of the data set size, QM performs best with both a large area for accurate predictions and a small tail of large errors.
PSON: A Serialization Format for IoT Sensor Networks
Authors: Luis Álvaro , Casares Pablo , Cuadrado-Gallego Juan J. , Patricio Miguel A.
Published: July 2021

In many Internet of Things (IoT) environments, the lifetime of a sensor is linked to its power supply. Sensor devices capture external information and transmit it. They also receive messages with control commands, which means that one of the largest computational overheads of sensor devices is spent on data serialization and deserialization tasks, as well as data transmission. The simpler the serialization/deserialization and the smaller the size of the information to be transmitted, the longer the lifetime of the sensor device and, consequently, the longer the service life. This paper presents a new serialization format (PSON) for these environments, which simplifies the serialization/deserialization tasks and minimizes the messages to be sent/received. The paper presents evaluation results with the most popular serialization formats, demonstrating the improvement obtained with the new PSON format.

Although cooperative social networks are considered key to human evolution, emphasis has usually been placed on the functions of men’s cooperative networks. What do women’s networks look like? Do they differ from men’s networks and what does this suggest about evolutionarily inherited gender differences in reproductive and social strategies? In this paper, we test the ‘universal gender differences’ hypothesis positing gender-specific network structures against the ‘gender reversal’ hypothesis that posits that women’s networks look more ‘masculine’ under matriliny. Specifically, we ask whether men’s friendship networks are always larger than women’s networks and we investigate measures of centrality by gender and descent system. To do so, we use tools from social network analysis and data on men’s and women’s friendship ties in matrilineal and patrilineal Mosuo communities. In tentative support of the gender reversal hypothesis, we find that women’s friendship networks in matriliny are relatively large. Measures of centrality and generalized linear models otherwise reveal greater differences between communities than between men and women. The data and analyses we present are primarily descriptive given limitations of sample size and sampling strategy. Nonetheless, our results provide support for the flexible application of social relationships across genders and clearly challenge the predominant narrative of universal gender differences across space and time.

Published: July 2021

Introduction. Optimization placement problems are NP-hard. In most cases related to cutting and packing problems, heuristic approaches are used. The development of analytical methods for mathematical modeling of the problems is of paramount important for expanding the class of placement problems that can be solved optimally using state of the art NLP-solvers.
The problem of placing two irregular two-dimensional objects in a convex polygonal region of the minimum size, which is a convex polygonal hull of the minimum area or perimeter, is considered. Continuous rotations and translations of non-overlapping objects are allowed.
To solve the problem of optimal compaction of a pair of objects, two algorithms are proposed. The first is a sequentially search for local extrema on all feasible subdomains using a solution tree. The second algorithm searches for a locally optimal extremum on a single subdomain using a "good" feasible starting point.
Purpose of the paper. Show how to construct a minimal convex polygonal hull for two continuously moving irregular objects bounded by circular arcs and line segments.
Results. A mathematical model is constructed in the form of a nonlinear programming problem using the phi-function technique. Two algorithms are proposed for solving the problem of placing a pair of objects in order to minimize the area and perimeter of the enclosing polygonal area. The results of computational experiments are presented.
Conclusions. The construction of a minimal convex polygonal hull for a pair of two-dimensional objects having an arbitrary spatial shape and allowing continuous rotations and translations makes it possible to speed up the process of finding feasible solutions for the problem of placing a large number of objects with complex geometry. Keywords: convex polygonal hull, irregular objects, phi-function technique, nonlinear optimization.
About Methods for Classifying Hidden Language Concepts in Specialized Texts Involving Pseudoinverse, Clustering and Data Grouping
Authors: Krak Iurii , Kulias Anatoliy , Petrovych Valentina , Kuznetsov Vladyslav
Published: July 2021

This paper discusses the problems of analysis of hidden language concepts in scientific texts in the Ukrainian language, using methods of text mining, dimensionality reduction, grouping of features and linear classifiers.
A corpus of scientific texts and dictionaries, as well as stop words and affixes, has been formed for processing specialized texts. The resulting texts were analyzed and converted into text frequency-inverse document frequency (TF-IDF) feature representation. In order to process the feature vector, we propose to use methods of dimensionality rteduction of the data, in particular, the algorithm for the synthesis of linear systems and Karunen – Loeve transform and grouping of features: T-stochastic grouping of nearest neighbors (T-SNE). A series of experiments were performed on test examples, in particular, for the determination of informational density in the text and classification by keywords in specialized texts using the method of random samples consensus (RANSAC). A method of classification of hidden language concepts was proposed, making use of clustering methods (K-means). As a result of the experiment, the structure of the classifier of hidden language concepts was obtained in structured texts was obtained, which gained a relatively high recognition accuracy (97 – 99 %) using such linear classification algorithms: decision trees and extreme gradient boost machine. The stability of the proposed method is investigated by using the perturbation of the original data by a variational autoencoder, test runs shown that sparse autocoder reduces the mean square error, but the separation band decreases, which affects the convergence of the classification algorithm.
In further research, we propose to apply other methods of analysis of structured texts and ways to improve the separability of specialized texts with similar authorial styles and different topic using a proposed set of parameters. Keywords: text processing, language concepts, pseudoinverse, clusterization, methods of data groupings.

Morgan found that the adi from of the clans formed on the basis of maternal rights, from which the clans based on paternal rights later developed. In this way we understand that the castes we see among the people who are tired of the ancient Social civilization are based on paternal rights and before that there were Social clans with maternal rights. As important as Darwin’s theory of evolution way in biology and how important Marx’s Philosophy of surplus value was in the field of Political, Economy, so important is the discovery that there was a Primitive maternal right that preceded patriarchy in civilized populations. The Social system that forgot this historical background enslaved the woman. set her aside from production. She was stripped of her rights and made to kneel before the man the began to paint her limbs. Myths about women and literary evidence in written form spilled out of masculine thought. Thus, the women become the most physically vulnerable in the attack on the country. In his poems, he shows the way in which the Tamil community considers activities that are considered sacred and pure. Malati Maitri writes about Social liberation, questioning the sacred practices of sacrifice, family morality, domesticity, motherhood and affection.

The majority of farmers are still unsure of which vegetable seeds are appropriate for planting on this property. This is due to farmers' lack of understanding of the conditions for planting these vegetable seeds on their fields. Due to farmers' and the general public's lack of understanding of land suitability evaluation, vegetable seeds have not been planted with optimum results because the requirements required for these vegetable crops do not match the land conditions that sustain vegetable growth. Understanding the significance of choosing vegetable seeds based on the adaptability of selecting land and plants also relies solely on farmers' scant knowledge. As a result, the authors believe that more research is needed to decide the best vegetable seeds for cultivation based on soil suitability and plant growth requirements. The AHP approach is very analytical and well-suited to determining the priority weight of each norm, which will later be used as a rating reference by the TOPSIS method. Based on the degree of soil suitability and the conditions for proper growth, it can be calculated that vegetable seeds will be planted later as an alternate, accurate, and dynamic approach

Since the emergence of the Covid-19 virus in Indonesia, learning activities in the education system have been changed to distance learning using online media. The most widely used application according to the results of interviews with teacher representatives from 4 vocational schools in Karawang Regency is Google Classroom. However, the application received a poor rating based on the rating on the Google Play Store. So that usability testing is carried out in order to assess the effectiveness, efficiency and user satisfaction of the application. There are several usability testing techniques, including (SUS) System Usability Scale and Usefull, Satisfaction and ease of Use (USE) Questionnaire. This study aims to obtain the results of usability testing and a comparison between the two techniques used. Both have some similarities where the analysis can be done using any media, it's just that there are differences in the number of questions and data analysis. The System Usability Scale (SUS) technique contains 10 questions while the Usefull, Satisfaction and ease of Use (USE) Questionnaire technique contains 30 questions with 3 main dimensions, namely Usefulness, Satisfaction and Ease of Use. The research method used is Product Moment Pearson’s method for data validity analysis and Cronbbach's Alpha method for data reliability  analysis. This research is a quantitative descriptive study conducted on 50 high school students/equivalent and university students. The results of the questionnaire technique (SUS) System Usability Scale state that Google Classroom has a good interface with a score of 72 with advantages in ease of use and desire to use it again, while based on the Usefull, Satisfaction and ease of Use (USE) Questionnaire technique states Google Classroom has an average value of 84% with 81% (usefulness), 86% (ease of use), 87% (ease of learning) and 83% (satisfaction). Then according to the comparison, the Usefull, Satisfaction and ease of Use (USE) Questionnaire technique is stated to be better with a reliability value of 0.967 while (SUS) System Usability Scale only has reliability (0.634).

The changes taking place in the modern world and in the education system in particular are characterized by continuity and abruptness, but they have a strong impact on people. Modern education is designed to help adults be resilient to change and capable of reactive adaptation based on lifelong learning. The actualization of non-formal and informal education is associated with a change in the social role of education in the information society, the transition from the implementation of the compensatory function to a comprehensive individual personal development. Active life position, participation in social projects, awareness of one's own life and educational goals are important components of ensuring the quality of life of modern man.

The modern concept of quality of life emphasizes the need to implement an authentic way of life, creating opportunities for the development of interpersonal relationships, conditions for various types of leisure, providing those needs that can’t be met only by material values, including educational. An adult during life has a steady need for education, due to the need to realize professional inclinations and abilities, personal interests and aptitudes. In this context, adult education is a tool for ensuring the quality of human life.

In today's world, improving the quality of life is inextricably linked with the development of education, which is a prerequisite for the country's competitiveness in the global division of labor. Successful are those countries that invest in education, its development and long-term growth. Therefore, education is a significant component of the process of ensuring the quality of life of the individual. Participation in trainings, professional communities, workshops, seminars contribute to the formation of an active life position and life trajectory, personal development of an adult and his goal-setting.
SEISMIC PERFORMANCE ASSESSMENT OF CONFINED ADOBE MASONRY STRUCTURES

This paper presents shake-table tests which were performed on two 1:3 reduce-scaled adobe masonry models confined with vertical and horizontal bands. The model AM1 consisted of bands (tie beam) at sill, lintel and eave levels, and lightly reinforced concrete (RC) columns at the corners. The model AM2 was similar to AM1 except that RC columns at the corners were not provided in this model. The models were subjected to sinusoidal base motions for studying their seismic performance. The lateral force-deformation capacity curves for both the models were developed and were bi-linearized to compute the response parameters including stiffness, strength, ductility and response modification factor (R). Seismic performance levels of both the models were defined and their seismic performance assessment was carried out to evaluate their suitability in different seismic zones. The use of vertical columns in the AM1 model considerably increased its lateral strength as compared to the AM2 model. Although R factor of 2.0 has been recommended for both the models, seismic performance of the AM1 model was found better in all seismic zones due to high lateral strength of this model.
