Collection And Management

<p>Garbage waste monitoring, collection and management is one of the primary concerns of the present era due to its detrimental effects on environment. The traditional way of manually monitoring and collecting the garbage is a cumbersome process as it requires considerable human effort and time leading to higher cost. In this paper, an IoT based garbage monitoring system using Thingspeak, an open IoT platform is presented. The system consists of an Arduino microcontroller, an ultrasonic sensor, a load cell and a Wi-Fi module. The Arduino microcontroller receives data from the ultrasonic sensor and load cell. The depth of the garbage in the bin is measured using ultrasonic sensor and the weight of the bin with garbage is measured from the load cell. The LCD screen is used to display the data. The Wi-Fi module transmits the above data to the internet. An open IoT platform Thingspeak is used to monitor the garbage system. With this system, the administrator can monitor and schedule garbage collection more efficiently. A prototype has been developed and tested. It has been found to work satisfactorily. The details are presented in this paper.</p>

Home automation is an automated system created specifically to facilitate the work of humans, especially at home. Home Automation connects electronic devices to each other in a home that is integrated using the internet network and allows it to be controlled via android smartphone and web client (server). On android smartphone installed applications that have been connected with Arduino microcontroller and Ethernet shield. In this research for controlling or retrieving data via Ethernet network the easiest is Arduino serve as server and we can request and arrange data through web client or android application then data will be sent using protocol User Datagram Protocol (UDP). So to control the electronic devices can be done from a considerable distance as long as connected to the internet.

Over Time

The use of passwords is one of the most popular ways to authenticate users on the Internet. Because of the specificity of storing passwords, developers are forced to impose restrictions on which passwords are safer to use. For example, most often a password must contain at least 8 characters, have letters of different registers, contain special characters, etc. It can be stated that over time, these restrictions only increase, and this in turn complicates the choice of a secure and at the same time easy-to-remember password. For example, the most secure password will contain 128 characters with maximum entropy. The article is devoted to user authentication, password entropy and valid passwords for websites, methods for improving authentication by developing a hardware password manager based on Arduino microcontroller. Thus, a password generated randomly has more entropy than a password generated by the user. The algorithm of the device includes functions of generating a password from the permissible characteristics and maximum entropy, storing the password on the device, improving security by confirming actions, reading the password from the device to the input line, and using the pin-code protection.

Every day, the technologies are expanding and developed with extra things to them. A cloud computing (CC) and Internet of things (IoT) became deeply associated with technologies of the internet of future with one supply the other a way helping it for the successful. Arduino microcontroller is used to design robotic arm to pick and place the objects by the web page commands that can be used in many industrials. It can pick and place an object from source to destination and drive the screws in into its position safely. The robot arm is controlled using web page designed by (html) language which contain the dashboard that give the commands to move the servos in the desired angle to get the aimed direction accordingly. At the receiver end there are four servo motors which are made to be interfaced with the micro controller (Arduino) which is connected to the wireless network router. One of these is for the arm horizontally movement and two for arm knee, while the fourth is for catch tings or tight movement. Two ultra-sonic sensors are used for limiting the operation area of the robotic arm. Finally, Proteus program is used for the simulation the controlling of robot before the hardware installation

Set Up

Malaria is an infectious disease that has a devastating effect on humans but is contagious and preventable. There were 228 million malaria cases globally in 2018, with 93% of patients and 94% dying showing up in Africa within Burundi, possessing a massive growth (51%). This study proposes an IoT design for smart monitoring and alert systems for malaria patients in Burundi. After being tested positive while they are home drinking tablets prescribed by the doctor, the patients will use a body temperature sensor. When the situation worsens, the patient shall be hospitalized and use the water level sensor to monitor the serum level, which contains quinine. Body temperature and water level sensor will be connected to Arduino Microcontroller, and all information will be gathered and sent to the IoT server through the internet. The system design is authentic and adequate in reducing mortality in Burundi. Besides, the system is equipped to set up a caution message to the medical staff in case of the patient's extreme conditions. It can be concluded that a Smart monitoring and alert system is essential for monitoring malaria patients and can alert in case of a severe condition.

Faktor Mensch

Dieser Beitrag beschreibt eine Möglichkeit, den Faktor Mensch bei der Planung manueller Montagevorgänge in der Mensch-Roboter-Kollaboration (MRK) zu berücksichtigen. Das Ziel ist die echtzeitfähige Prädiktion der Dauer des Montageprozesses auf Mikro-, Meso- und Makro-Ebene der Produktion auf Basis von Methods-Time Measurement (MTM). Darauf aufbauend soll durch Adaption der Montagedauer eine ergonomische Interaktion zwischen Mensch und Roboter geschaffen werden. &nbsp; This paper describes one way to consider human factors when planning manual assembly processes in human-robot collaboration (HRC). The goal is the real-time prediction of the duration of the assembly process on the micro-, meso- and macro-level of the production based on Methods-Time Measurement (MTM). This prediction is then used for an ergonomic human-robot interaction design by adapting the predicted assembly durations.

The Information SuperHighway, Email, The Internet, FTP, BBS, Modems, : all buzz words which are becoming more and more routine in our daily life. Confusing terminology? Hopefully it won't be in a few minutes, all you need is to have a handle on a few basic concepts and terms and you will be on-line with the rest of the "telecommunication experts". These terms all refer to some type or aspect of tools associated with a range of computer-based communication software and hardware. They are in fact far less complex than the instruments we use on a day to day basis as microscopist's and microanalyst's. The key is for each of us to know what each is and how to make use of the wealth of information which they can make available to us for the asking. Basically all of these items relate to mechanisms and protocols by which we as scientists can easily exchange information rapidly and efficiently to colleagues in the office down the hall, or half-way around the world using computers and various communications media. The purpose of this tutorial/paper is to outline and demonstrate the basic ideas of some of the major information systems available to all of us today. For the sake of simplicity we will break this presentation down into two distinct (but as we shall see later connected) areas: telecommunications over conventional phone lines, and telecommunications by computer networks. Live tutorial/demonstrations of both procedures will be presented in the Computer Workshop/Software Exchange during the course of the meeting.
