This paper addresses the issue of ensuring the asymptotic stability of the two-dimensional discrete Roesser model. Most of the emphasis is given now a days on the stability analysis of two-dimensional discrete models because of their wide variety of real time applications. When it comes of ensuring the stability of any system, the most generalized method is to use symmetric Lyapunov function. There have been a lot of published articles in which the stability of the system has been ensured using the symmetrical Lyapunov function, but use of unsymmetrical Lyapunov function has not been adopted due to the computational complexity. One of the very popular two dimensional discrete model is the Roesser model, which is structurally different from other two dimensional discrete models and has its wide applications in the field of image processing. In this article the stability of a 2-D discrete Roesser model has been ensured using the unsymmetrical Lyapunov function, which is a more generalized way of ensuring the stability of any system. Accordingly, new stability conditions have been developed, which is an extension of the previously reported methods in which the stability is made certain using the symmetrical Lyapunov matrix. In some cases, it has been shown numerically that it is difficult to ensure stability using the symmetric Lyapunov matrix but still, the stability for such cases may be ensured using the unsymmetric Lyapunov matrix. In addition, symmetrical Lyapunov matrix stability conditions have also been derived using the unsymmetric Lyapunov matrix. The stability criteria have been checked and ensured based on newly developed stability conditions by considering two different examples. An effort has been put in reducing the conservatism with the new stability conditions.

A method was developed using liquid chromatography tandem mass spectroscopy for the identification and quantification of multi residues of pesticides. The present study is first of this kind, destined purely to understand the interaction between the clean-up agents with 103 pesticides. The QuEChERS clean-up, employing most commonly used clean-up agents like anhyd.MgSO4, PSA, C-18 and GCB in twelve combinations, was performed to assess their adsorption behavior with the pesticides. Recovery studies at 1μg∙mL−1 showed that anhyd.MgSO4 gave acceptable recovery for 100 pesticides (97.08%) in treatment T1. The PSA adsorbed some polar and acidic pesticides onto it and gave acceptable recovery for < 90% pesticides in T2 to T5 and C-18 with anhyd.MgSO4 & varying amount of PSA (T6, T7) gave a lower, but acceptable recovery of 83.49% pesticides. GCB with anhyd.MgSO4 & varying amount of PSA (T8, T9), adsorbed some planar pesticides like carbendazim, tricyclazole and gave a lower, but acceptable recovery for 74.75 – 77.66% pesticides. In T10 to T12, when all the adsorbents were used, adsorption of polar, acidic and planar pesticides (25.24%) was observed while rest of the pesticides (74.75%) gave acceptable recovery. The method also satisfied the single laboratory validation criteria for linearity, specificity, accuracy and precision.

In this study, sonication treatment at 35 kHz for 0, 5, 15, 30, and 60 minutes (at 20°C) and thermal pasteurization at 95°C for 15 seconds were applied to freshly squeezed mandarin juice to determine the effects on physicochemical properties, bioactive compounds, and other quality parameters. The changes for pH, titratable acidity, water activity, browning index, total flavonoids, antioxidant activity, ascorbic acid contents, color, and cloud (in sensory analysis) were insignificant. However, increases in viscosity, ash, turbidity, and color values and decreases in enzyme activities were observed after the sonication treatment. Overall, for 15 minutes treatment, significant enhancement in total phenolics and ascorbic acid content was observed. Results suggest that 15 minutes of sonication treatment could contribute to the improvement of the quality of mandarin juice and therefore, it is possible to employ this treatment in mandarin juice processing successfully.

In this study, a new classification technique is proposed to distinguish the appropriate one from four different nitrogen (N)fertilizer doses (0, 40, 80, and 160 kg ha−1) using six triticale cultivars. In the classification phase, nine yield featuresfrom 30 plants of the same cultivar were measured, that is, each dose or class has 30 feature vectors consisting of ninefeatures. Next, six triticale cultivars were classified for each dose of N fertilizer separately by using 30 feature vectorsbelonging to each dose. Similarly, the same classification task was repeated by using all feature vectors taken from fourdoses of N fertilizer. What makes this study novel is the classification process of six triticale cultivars by taking into accounttheir characters based on different doses of N fertilizer. The classification tasks were conducted by applying CommonVector Approach, Support Vector Machine, k-Nearest Neighbor, and Decision Trees algorithms. While satisfactory resultswere obtained from the training sets for all cases, the test set accuracy is relatively lower for the classification of four dosesof N fertilizer and six cultivars since features extracted from different doses of N fertilizer for the same cultivar are close toeach other. Furthermore, the number of feature vectors is insufficient to classify classes efficiently. Interestingly, when thecommon information of the classifiers was extracted with the biplot technique, useful results were obtained in selectingappropriate N doses for several triticale varieties. Combined with the results of future comprehensive studies, applicableresults for the agricultural sector can be proposed.
本研究以6个小黑麦品种为研究对象，提出了一种新的分类技术，以区分4种不同施氮量(0、40、80和160 kg ha - 1)的适宜施氮量。在分类阶段，测量同一品种30株的9个产量特征，即每个剂量或类别有30个特征向量，由9个特征组成。其次，利用各施氮量所属的30个特征向量，分别对6个小黑麦品种进行分类。同样，使用4个氮肥剂量的所有特征向量重复相同的分类任务。本研究的新颖之处在于根据不同施氮量对6个小黑麦品种的性状进行分类。采用CommonVector方法、支持向量机、k近邻和决策树算法进行分类。虽然所有情况下的训练集都获得了令人满意的结果，但由于从同一品种不同剂量的氮肥中提取的特征彼此接近，因此对于4种氮肥和6种品种的分类，测试集的准确性相对较低。此外，特征向量的数量不足以有效地分类。有趣的是，当用双图技术提取分类器的共同信息时，在几种小黑麦品种的适宜施氮量选择上获得了有用的结果。结合未来综合研究的结果，可以提出适用于农业部门的结果。

This paper reports a distinctive property of hierarchical mesoporous ZnAlPO4 for benzene to aniline reaction, with 99% selectivity using aqueous ammonia as amine source in presence of hydrogen peroxide at mild reaction conditions (70℃ and atmospheric pressure). The catalyst is synthesized by a simple, solvent-free mixing method, which significantly improves properties such as acidity and porosity of the material is gained by increasing the temperature of the physical mixture from room temperature (25ºC) to 100ºC. Detailed characterization analysis by FT-IR, SEM, TEM, XRD, TPD, XPS, and N2 adsorption–desorption studies of the material helped in understanding the direct amination activity of the material.

Sustainable and smart management of public transportation systems depends on continuous monitoring and analysis of the data collected at regular intervals. One of the key research topics in this area is determining bus service frequency and developing appropriate schedules. The number of buses and their frequencies have a significant impact on the entire transportation system, affecting all users of the network. To address this issue, bus service frequencies during peak hours should be determined based on passenger demand. In this study, the daily frequencies of the bus system of a city (Denizli, Turkey) were investigated, the carbon footprints of the system were analyzed, and suggestions were provided. This is determined by the model developed regarding the linear optimization method. The goal programming approach is used in the analysis. The existing frequencies are compared with that provided by the goal programming approach. Additionally, the results obtained are investigated by a cost analysis regarding different benefit rates (carbon footprint, total kilometer, and passenger comfort) for the public. By implementing the recommended bus service frequencies, significant financial and environmental improvements can be achieved.

The fifth of the 17 Sustainable Development Goals (SDGs) included in the Sustainable Development Agenda is gender equality. Despite advances in recognizing women's contributions in many areas of life, society has yet to fully appreciate women's positions and influence in business. Financial sustainability, on the other hand, has attracted scholarly attention for several decades as a crucial condition for sustainable growth. Therefore, the present study investigates the influence of women in top management on business financial sustainability. It uses a sample of 55158 firms from 82 developing countries from 2015 to 2022, World Bank Enterprise surveys, in order to examine whether firms’ gender diversity influences financial sustainability. Findings document that firms with females’ top managers are financially more sustainable than their male-led counterparts. Results also indicate that the effect of female in top management on firm sustainability varies between regions. The study's findings give critical management and policy insights into corporate financial sustainability. Gender diversity should be considered by managers and policymakers as a strategy for firms to achieve financial sustainability and ultimately to contribute to the sustainable development agenda.

The work is on the use of a robot as a guide that takes visitors for a guided tour around a facility. A past project of the research group proposed a robot guide that enacted a pre-recorded tour, however, had a limited applicability as the humans rarely followed the guided tour and the robot did not respond to the movement of the visitors. A robotic guide must ensure that it takes the visitors along, who are not left behind, while typically maintaining comforting distances from the visitor. The width and height of the human face is computed which is inversely proportional to the distance of the person from the robot. Further, we construct a method which guides visitors cooperatively. The robot moves sequentially to different locations with the visitors, and if any visitor is found missing, the robot stops and waits for that visitor. When the visitor becomes visible, the robot resumes the journey. The robot moves and navigates as a guide for a group of visitors maintaining appropriate distances from the visitor using the distance measurement methodology. The results are demonstrated by making the robot take visitors on a guided tour of the Robotics and Machine Intelligence Laboratory. The robot waits if a visitor leaves the group for calls or any other reason, while also waits if the visitors lag behind. The work demonstrates the ability of a robot to be socially complaint while taking a group of visitors on a guided tour.

Manual ginger planting is a tedious, drudgery-prone, and time-consuming operation, due to the constant bending posture during planting. To address this issue, a seed metering mechanism was developed and evaluated at the ICAR-Central Institute of Agricultural Engineering, Bhopal. The metering mechanism consisted of a vertical rotating disc, fingers, lever and cam, seed hopper, agitator, and rhizome delivery system. The laboratory study was conducted using a sticky belt set up to determine the seed distribution pattern at different forward speeds (0.42 m/s, 0.56 m/s, 0.69 m/s, and 0.83 m/s), rhizome sizes viz. small (< 35 mm), medium (35–50 mm), and large (> 50 mm), and types of pickup fingers (P1 and P2). The factorial CRD design with three replications for each variable was used in the laboratory experiment. The performance parameters were measured, including average spacing, missing index, multiple index, quality of feed index and visible damage. The result revealed that speed of operation, seed size and finger type had statistically significant effects on the average seed spacing. As the speed of operation and seed size increased, the multiple index and Quality of Feed Index (QFI) decreased, while the missing index and damage percentage increased for both types of fingers. The main factor significantly influencing the performance indices was the speed of operation. The highest QFI of 77.14% was observed at the forward speed of 0.56 m/s for P2 fingers. The lower values of miss index, multiple index, and visible damage were observed with P2 as compared to P1. The visible damage was observed to increase at increasing speeds and seed sizes for both types of fingers. The performance of the metering system was found satisfactory with finger (P2) at the optimum speed of 0.56 m/s for medium seed sizes. The automatic seed metering mechanism holds great potential for ginger planting to improve accuracy, efficiency, yields, and cost-effectiveness.

The lower values of miss index, multiple index, and visible damage were observed with P2 as compared to P1. The visible damage was observed to increase at increasing speeds and seed sizes for both types of fingers. The performance of the metering system was found satisfactory with finger (P2) at the optimum speed of 0.56 m/s for medium seed sizes. The automatic seed metering mechanism holds great potential for ginger planting to improve accuracy, efficiency, yields, and cost-effectiveness.","PeriodicalId":17010,"journal":{"name":"Journal of Scientific & Industrial Research","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135762842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
This study analyzes effects of vibrations on comfort and road holding capability of vehicles as observed in variations of suspension springs, road roughness etc. Also, design of non-linear experimental car suspension system for ride qualities using neural networks is presented. Proposed active suspension system has been found more effective in vibration isolation of car body than linear active suspension system. Proposed neural network predictor could be used in vehicle’ s suspension vibration analysis .
