Distance Testing on Point To Point Communication with Lora Based on RSSI and Log Normal Shadowing Model
No full textBig cities are currently implementing the smart city concept, where Internet of Things (IoT) sensors are placed on the roads, then the data is collected and processed by smart devices to solve urban problems. IoT implementation is suitable using LoRa technology. In this paper, distance testing is carried out on point to point communications with LoRa in urban areas at a frequency of 915 MHz. The RSSI (Received Signal Strength Indicator) parameter value is what is observed, and the log normal shadowing model is used to compare the RSSI values computationally. The test results for the farthest distance were 3.37 km with an RSSI value of -104.5 dBm. The error value between the measured and calculated RSSI values is 7.3% where a path loss exponent (n) of 1.6 from the measurement results

Design of Picohydro Power Plant for Application of River-based Garbage Lifting Tool IoT
Get PDFUtilizing water energy can be implemented on small scale, such as with a (PLTPH), which is a small-scale power plant using water as its driving force through a penstock to move a turbine. By applying a river trash lifter based on IoT, the cleanliness of the river environment can be managed. the power source comes from a generator coupled to a Pelton turbine type, which will rotate the generator to produce VAC electricity that will first be converted to VDC voltage so that the voltage is more stable and then converted back to 220 VAC voltage by an inverter. This will become the main energy source for the IoT-based river trash lifter using the Wemos D1 R1 microcontroller as the system's brain to control and collect data from two HC-SR04 ultrasonic sensors, which will be monitored on an LCD display and Telegram notifications. Test results show that water pressure greatly affects the performance of the PLTMH prototype design, with a minimum water pressure required for the PLTMH to work being 18 psi. The generator can produce 60 VAC voltage with an average voltage of 50.05 VAC and an average generator current of 0.046 amps. The power on the generator depends on the voltage and current produced. The load on the generator after being converted to DC current is 9 watts. The duration of the conveyor operation to lift trash from the river to the collection bin depends on the HC-SR04 ultrasonic sensor placed in the river when it detects trash, which will be displayed on the LCD. When the collection bin is full, the HC-SR04 ultrasonic sensor in the collection bin will activate a buzzer, which will be displayed on the LCD and the ThingSpeak
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
