Buzzer

Generally, blind people use a traditional cane (known as white cane) for moving from one place to another. Although, white cane is the international symbol of blindness, it could not help them to detect place and to avoid obstacles. In this paper, we represent a model of walking stick for blind people. It consists of GPS module, GPS Antenna, Arduino, ultrasonic sensor and buzzer. This stick can detect place and obstacles. Position detection part is done with GPS module and GPS antenna. Ultrasonic sensor is used for detecting obstacles. Here, the buzzer produces two types of sound. When the blind reaches to his destination, buzzer buzzes continuously. When the blind faces any obstacles, buzzer buzzes with interruption. By discovering these two types of sound, blind can be confirmed about his destination and also can avoid obstacles in front of him. The whole system is designed to be small, light and is used in conjunction with the white cane so that it could ensure safety of the blind.

This paper based on automated system for ticketing in the Metro Train System which is based on unique passenger identification. This is a user friendly system, which will automatically identify the passenger and deduct the passenger's fare according to the distance travelled. The Radio Frequency Identification (RFID) card and rfid reader are used to make the identification of passenger and transaction very precise. System thus reduces human errors and efforts. This project is a complete metro train simulator that will be installed in a metro train. The RF Card technology is used that is it has a unique id for every tag. Every person is allotted a RF card with the fixed balance in it. The metro train will keep on passing between the stations and as it stops at the station the person has to swipe its RF card to make an exit. According to distance travelled by the passenger the ticket is deducted from its balance, as the person has to show the RF card while entering and leaving the train station. The MCU is used to perform the above task along with the display unit and RF ID reader. A stepper motor is used to show the door opening and closing on swiping the RF card.

Through this chapter I attempt to argue that buzzer operations in Indonesia are not merely in the form of click farms whose operators are driven by monetary incentives, but a creative labor that is contextualized by the moral world of the actors enmeshed within Indonesian political culture. Buzzing is not always a mere work, but can also be a political play through which they gain a sense of agency. Further, I argue that we cannot isolate the phenomenon of political buzzer as a uniquely digital phenomenon. In this case, buzzer subcontract work is intertwined with the phenomenon of political voluntarism. As I will demonstrate, buzzer subcontract work lives on a certain moment where Indonesian media ecology plays a vital role in informing and involving public engagement with politics— where there is a feedback loop between news outlets and social media—in which middle class citizens are involved as netizens.

Abnormal event detection is now a challenging task, especially for crowded scenes. Many existing methods learn a normal event model in the training phase, and events which cannot be well represented are treated as abnormalities. It fails to make use of abnormal event patterns, which are elements to comprise abnormal events. Moreover, normal patterns in testing videos may be divergent from training ones, due to the existence of abnormalities. Anomaly detection finds extensive use in a wide variety of applications such as fraud detection for credit cards, insurance or health care, intrusion detection for cyber-security, fault detection in safety critical systems, and military surveillance for enemy activities. The proposed detector treats each sample as a combination of a set of event patterns. Due to the unavailability of labeled abnormalities for training, abnormal patterns are adaptively extracted from incoming unlabeled testing samples. It detects the moving object using Gaussian Mixture Model based on foreground detection and the abnormalities in the videos are detected.

This work focuses on using rain sensor, and it can be used in both everyday life and manufacturing. The ultimate goal of this project is to detect rain using a rain sensor.

Network management platforms provide flexible facilities for setting up custom applications able to detect network anomalies on a specific environment. This is because each network is made of users, services and computers with a specific behaviour that is then reflected in the generated network traffic. Goal of this paper is to show that in every network there are some global variables that can be profitably used for detecting network anomalies, regardless of the type of network users and equipment. As most of the relations among these variables are fixed, this paper shows that it is possible to define generic network rules aimed to automatically detect selected network anomalies. Finally, it covers the design and implementation of an open-source application used to effectively validate this work on a large campus network.

Pests are one of the main obstacles for farmers that can cause a decrease in the amount of crop production. One of the pests that often disturb farmers, especially for chili farmers or other horticultural crops, is the fruit fly. This pest is very disturbing harvests because their numbers are increasing quite rapidly. This problem underlies the development of this pest repellent. The working principle of this tool is to repel fruit flies using ultrasonic waves without using pesticide drugs that can damage the environment if used continuously. This tool is designed using Arduino Uno as the main controller. Ultrasonic waves and generated and regulated using piezoelectric at a certain frequency as a fruit fly repellent. Then the tool is rotated using a servo motor to reach all corners of the land. For control and monitoring, this tool uses the GSM SIM800L version 2 module for sending short messages. From the results of the overall evaluation, this fruit fly repellent can work according to its function. This can be proven by testing when not using a fruit fly repellent, there are a lot of flies trapped in the bait bottle totaling 30, while when given a repellent, the flies trapped in the bait bottle are reduced to 15 with the information that the buzzer can emit sound, and servo motor moving condition, as well as GSM SIM800L, can send messages to the sender.

Based on digital ethnographic research and interviews, this article examines the use and abuse of the state ideology Pancasila among political buzzers (or cyber troops, persons tasked in online political communication) in Indonesia.

In contrary to false dichotomy of pro-diversity pro-government 'cebong' vs pro-Islamism opposition 'kadrun', both sides appear to invoke the languages of state ideology and nationalism to make their point - perhaps not too dissimilar from New Order political language. We call for the need to strip away this loyalty to the nation-state.

The ultrasonic motion detector devices emit ultrasonic sound energy into an area of interest (monitored area), and this further reacts to a change in the reflected energy pattern. The system uses a technique that is based on a frequency shift in reflected energy to detect a movement or change in position (motion). In this system, ultrasonic sound is transmitted from the transmitting device which is normally in the form of energy. The transmitted sound utilizes air as its medium and this travel in a wave type motion. The wave is reflected back from the surroundings in the room/hallway and the device hears a pitch characteristic of the protected environment. In this system, the wave pattern is disturbed and reflected back more quickly, thus increasing the pitch and signaling an alarm whenever motion is detected. The main contribution of this work is the design of a circuit that can sense motion through movement of anything, a low cost and portable motion detector, and the design of a circuit that can be used to trigger another circuit whether to ON or OFF depending on the circuit attached to it. Generally, the design is made to detect movement or moving object in a an enclosed area. In this work, a transmitter transducer generates a signal at a frequency of 40khz, and when the signal is blocked by any moving object, and this in turn, triggers a buzzer via a timing circuit. This system works on the principle of the signal interference by a moving body, and the system is dependent on the presence of an intruder or moving object within a monitored area. The system after design and construction was tested and found to work in accordance with specifications.

In ATM machines the user is identified by inserting an ATM card and authentication is provided by the customer entering a PIN. The PIN provided by the customer is compared with the recorded reference PIN within the bank Server. If the customer forgets the PIN after 3 trials ATM cards are blocked, to reactivate he needs to attend the bank and do the formalities which could be a time consuming job. So fingerprint biometric is introduced to cut back this sort of error. This project aims at exploring the system to secure ATM pins and passwords with the fingerprint data specified only the legitimate user can access the pins and passwords by providing the valid fingerprint.
