DESIGN AND IMPLEMENTATION OF MACHINE-CONTROLLED SYSTEM FOR PUBLIC BICYCLE-SHARING IN URBAN AREAS

This paper presents a design of machine controlled intelligent system for public to share bicycles for short distance transportation in urban areas. It allows us to take bicycle from wherever we are and to park at our nearest place of destination. The design schemes used here are automated system for bicycle delivery unit (base station) and bicycle parking unit (substation) and automatic amount collection for the usage from user card (RFID tags) and central administration office (GPS) and solar powered substations (PV solar panels). Moreover, it offers auto-locking racks for bicycles, on-Board vehicle tracking, and battery with solar power management, data logging, and communication with substations and administration. The subscribers can register to this service by administrator of bicycle sharing system. In 2011, the Ministry of Urban Development (MOUD), Government of India, launched the National Public Bicycle Scheme (NPBS) to build capacity for the implementation and operation of cycle sharing systems across the country. This paper outlines the advanced requirements to successfully develop and deploy bicycle sharing system focusing on solar powered battery charging and vending by PV solar panels, rental collection interface, in and out management of bicycles, system equipped with RFID and GPS tracking mechanisms. So bicycle sharing systems has emerged as an innovative form of public transport to provide urban short-distance transportation services by government

A Novel Chimp Optimized Linear Kernel Regression (COLKR) Model for Call Drop Prediction in Mobile Networks

Call failure can be caused by a variety of factors, including inadequate cellular infrastructure, undesirable system structuring, busy mobile phone towers, changing between towers, and many more. Outdated equipment and networks worsen call failure, and installing more towers to improve coverage might harm the regional ecosystems. In the existing studies, a variety of machine learning algorithms are implemented for call drop prediction in the mobile networks. But it facing problems in terms of high error rate, low prediction accuracy, system complexity, and more training time. Therefore, the proposed work intends to develop a new and sophisticated framework, named as, Chimp Optimized Linear Kernel Regression (COLKR) for predicting call drops in the mobile networks. For the analysis, the Call Detail Record (CDR) has been collected and used in this framework. By preprocessing the attributes, the normalized dataset is constructed using the median regression-based filtering technique. To extract the most significant features for training the classifier with minimum processing complexity, a sophisticated Chimp Optimization Algorithm (COA) is applied. Then, a new machine learning model known as the Linear Kernel Regression Model (LKRM) has been deployed to predict call drops with greater accuracy and less error. For the performance assessment of COLKR, several machine learning classifiers are compared with the proposed model using a variety of measures. By using the proposed COLKR mechanism, the call drop detection accuracy is improved to 99.4%, and the error rate is reduced to 0.098%, which determines the efficiency and superiority of the proposed system

Effect of Yogasana and Aerobic exercise on selected physical variables of university women students / G .Vasanthi

The aim of this study is to determine the effect of yoga asana and aerobic exercises on selected physical fitness variables of university women students. Thirty healthy, untrained women subjects were selected from the hostels of Pondicherry University and their age ranged from 20 to 25 years. The subjects were equally divided into three groups namely control and two experimental groups. Control group (Group I) did not undergo any training programme rather than their daily routine work. The experimental group (Group II) underwent yoga asana practice and (Group III) were treated with aerobic exercises for forty five minutes duration for twelve weeks except Saturday and Sunday. Static balance and flexibility were measured through field tests. The flexibility and static balance was measured before and after the completion of yoga asana practice and aerobic training. The results of pre-test and post-test were statistically analyzed by using Analysis of Co-variance. The result revealed that flexibility and static balance had significant improvement due to the practices of yoga asana and aerobic training when compared to the control group. The result when compared between the two experimental groups revealed that the yoga asana group had significant effect on flexibility and static balance than the aerobic group

Leveraging quick response (QR) Codes for horticultural information access: A stakeholder perspective

In the context of horticulture’s crucial role in economic growth, nutritional security and employment, the sector faces challenges related to dissemination of credible scientific information, particularly in rural areas. The gap in information access leads farmers to rely on experiential knowledge and peer opinions. Leveraging information and communication technology (ICT), specifically quick response (QR) codes, presents an innovative solution to bridge this information gap. This paper investigates stakeholders’ awareness, utilization, size and display distance and constraints in utilizing QR codes for accessing horticultural information. The findings indicated that 93.33% of the respondents reported previous usage, highlighting the technology’s ubiquity and acceptance. Moreover, stakeholders expressed positive inclination towards QR code adoption for accessing horticultural information, with 53.33% expressing likelihood to embrace QR technology. Effect of QR code size on the display board and their display distance on the usability and adoption was also studied, which indicated, 71.22% accessed QR codes on large displays of size 8" x 11", while, 16.66% accessed them on small displays of size 4" x 5". However, despite the positive reception, several challenges impede QR code utilization. Poor internet network connectivity (mean score: 71.00) during National Horticultural Fair (NHF-2024) emerges as a significant barrier, alongside entrenched preferences for traditional methods (mean score: 69.00). By aligning QR code designs with stakeholders’ preferences and addressing constraints, horticultural stakeholders can leverage QR codes more effectively, fostering knowledge dissemination and driving horticultural development

Complete breakdown of the Debye model of rotational relaxation near the isotropic-nematic phase boundary: Effects of intermolecular correlations in orientational dynamics

The Debye-Stokes-Einstein (DSE) model of rotational diffusion predicts that the rotational correlation times $\tau_{l}$ vary as $[l(l+1)]^{-1}$, where $l$ is the rank of the orientational correlation function (given in terms of the Legendre polynomial of rank $l$). One often finds significant deviation from this prediction, in either direction. In supercooled molecular liquids where the ratio $\tau_{1}/\tau_{2}$ falls considerably below three (the Debye limit), one usually invokes a jump diffusion model to explain the approach of the ratio $\tau_{1}/\tau_{2}$ to unity. Here we show in a computer simulation study of a standard model system for thermotropic liquid crystals that this ratio becomes much less than unity as the isotropic-nematic phase boundary is approached from the isotropic side. Simultaneously, the ratio $\tau_2/\eta$ (where $\eta$ is the shear viscosity of the liquid) becomes {\it much larger} than hydrodynamic value near the I-N transition. We have also analyzed the break down of the Debye model of rotational diffusion in ratios of higher order rotational correlation times. We show that the break down of the DSE model is due to the growth of orientational pair correlation and provide a mode coupling theory analysis to explain the results.Comment: Submitted to Physical Review
