Abstract A three-component model for a belted radial tire, previously developed by the authors for free rolling without slip, is generalized to include longitudinal forces and deformations associated with driving and braking. Surface tractions at the tire-road interface are governed by a Coulomb friction law in which the coefficient of friction is assumed to be constant. After a brief review of the model, the mechanism of interfacial shear force generation is delineated and explored under traction with perfect adhesion. Addition of the friction law then leads to the inception of slide zones, which propagate through the footprint with increasing severity of maneuvers. Different behavior patterns under driving and braking are emphasized, with comparisons being given of sliding displacements, sliding velocities, and frictional work at the tire-road interface. As a further application of the model, the effect of friction coefficient and of test variables such as load, deflection, and inflation pressure on braking stiffness are computed and compared to analogous predictions on the braking spring rate.

There is an increased prevalence of heart diseases in developing countries and continuous monitoring of heart beats is very much important to reduce hospital visits, health costs and complications. The Internet of Things (IoT) equipped with microcontrollers and sensors can give an easy and cost-effective remote health monitoring. We developed a Heart Beat monitoring module based on an android application. The software involved was the Android Application developed using Android Studio, which is the Integrated Development Environment (IDE). This app retrieved the data from the open IoT platform thingspeak.com. A highly sensitive Pulse Sensor was used to measure the heartbeat of the patient automatically. An Arduino Uno microcontroller interfaced with a Wi-Fi module ESP8266 used to transmit pulse reading over the internet using Wi-Fi. The heartbeat was displayed on the LCD of the patient in run-time. The heartbeat in beats per minute (BPM) was plotted against time (minutes). A mounted pulse sensor to the patient had monitored the heartbeat and transmitted it in the form of voltage signal to the microcontroller, which converted it back into a mathematical value. The Arduino transmitted the data onto the thingspeak.com portal, where it was plotted on a graph and the values were stored for future assessment. The user of the app was given a things peak API and the channel number as an access code, through which physician or nurse can accessed the patient’s data. IoT based heartbeat module as an android application can provide a convenient, cost effective and continuous remote measurements for heart patients to help physicians and nurses update. This app can reduce the burden of hospital visits or admissions for elderly patients.

Saat ini banyak orang tua memberikan fasilitas smartphone pada anaknya dengan alasan agar komunikasi antara mereka tetap terjaga, terutama bagi orang tua yang sibuk dengan karirnya. Namun sayangnya, kecendrungan anak-anak untuk memilih bermalas-malasan dengan smartphone yang dimiliki dibandingkan dengan melaksanakan kewajiban mereka. Sehingga smartphone yang harusnya memberikan manfaat positif justru menjadikan perilaku anak cenderung mengarah ke hal yang negatif. Oleh karena itu, dibutuhkan sebuah aplikasi mobile untuk orang tua dan anak yang dapat membantu mengurangi perilaku negatif anak menjadi ke arah yang lebih positif. Metode waterfall digunakan untuk pembangun aplikasi ini. Sedangkan untuk pembuatan aplikasi ini, penulis memilih Android Studio sebagai Integrated Development Environment (IDE) untuk pengembangan aplikasi. Aplikasi Parenting berbasis Android ini dapat membantu orang tua dalam pembentukan perilaku positif anak disamping kesibukannya. Pada aplikasi ini, orang tua dapat memberikan daftar tugas yang harus diselesaikan olah anak dengan rentang waktu tertentu. Pada login anak, anak dapat memberikan status tugas yang telah diberikannya. Jika anak telah menyelesaikan tugasnya, orang tua dapat memeriksa dan memberikan skor tugas tersebut, dimana skor tersebut akan terakumulasi. Pada posisi skor tertentu, orang tua dapat memberikan reward kepada anaknya

Among the measures aimed at the effective performance of public services in a modern urban environment, one of the main is the quality control and efficiency of the work performed. Timely street cleaning is hampered by several groups of problems, including the lack of a single automated information system (AIS) control of the work performed. In this regard, there is a need to improve and automate this area. This approach will allow you to combine high performance due to the speed of the system and effective quality control of street cleaning. The purpose of this work is the study and analysis of existing information systems (is), allowing to automate the process of quality control and operational performance of the above tasks. On the basis of the conducted researches, to develop is, having coordinated with the customer (administration of the Central district of Krasnoyarsk) requirements and functionality which allow to automate this process.This article presents the main aspects of the design and software solutions for the implementation of the algorithm in the form of AIS, designed to automate the process of monitoring the cleanliness of streets in the city. The development of AIS was conducted in the PhpStorm integrated development environment in the PHP programming language.
