The purpose of this study was to study a relation between the electrical conductivity (EC) and the pH of the hydroponic nutrient mixing system and to find out EC and pH adjusting equation by using linear regression analysis in order to generate the mathematical equation. In the experiment use Green oak information to set EC and pH target in equation for adjusting. From the experiment researcher found...
Conference proceedings front matter may contain various advertisements, welcome messages, committee or program information, and other miscellaneous conference information. This may in some cases also include the cover art, table of contents, copyright statements, title-page or half title-pages, blank pages, venue maps or other general information relating to the conference that was part of the original...
Chords transposer based on Optical Character Recognition (OCR) aimed to increase-decrease chords progression of musical chords in musical websites. By using the OCR, we can transform the information of image into the information of text which is easy to manipulate. In our proposed method, the chords transposer will change captured image of chords and lyrics into character or text-chords. The text...
This paper presents the statistics-based algorithm in order to increase the accuracy of the obstacle range measurement. This research is implemented on the concept of filtering approach and is only applied for the low-cost ultrasonic range sensor. The experiments are conducted on the HC-SR04 module and results are compared to the traditional methods. The results are shown that the accuracy of this...
The automated segmentation of cell nuclei is critical for diagnosis and classification of cancers in pleural fluid. This task is very essential since the morphology of cell nuclei such as the size, shape and stained color are mainly associated with cells proliferation and malignancy. It remains challenging due to the inconsistent stained color, poor contrast, the variety of cells, and the large amount...
Diabetic retinopathy is one of the complicated diseases which occurs in diabetic patients when the affects damage the retina. The eyes vision can lead to be lost in case of late treatment. Microaneurysms are the earliest detectable abnormalities of diabetic retinopathy, so the automated detection of the lesions is essential and useful task. This paper proposed a simple method to detect microaneurysms...
This paper presents the framework for low-cost gaze estimation system to find the polynomial model used in with head pose based system. This framework uses three features - center of pupil, glint, and inner eye corner to create the polynomial model. The pupil-glint vector used to estimate eye gaze while glint-inner eye corner vector used to estimate head pose and adding inner eye corner to the model...
Monitoring ocean acidification (OA) is very important for healthy fisheries and marine ecology systems, especially in coastal areas, like the Boston Harbor and the Massachusetts Bay areas. This problem is particularly exacerbated in this region as it is related to the so-called reduced “buffering capacity” of the New England coastal waters. Sea Surface Temperature (SST) is one of the significant OA...
With continuous declines in circulation and advertisement volume, China's newspapers have been trying hard in service and organization innovations. We explored major journals and reports on media innovations, identified five main directions of service innovations for China's newspapers and discussed about them one by one.
This paper presents a simple and low-cost array antenna configuration. The proposed antenna configuration was designed to operate at the center frequency of 2.4 GHz for Wireless Local Area Network (WLAN) applications. The antenna consists of 2 couple conductor patches printed on the dielectric substrate placing in parallel and separate by the spacing between patch. The results have shown that the...
This article presents a high isolation two probes feed microstrip antenna for dual-polarization applications. The high isolation is achieved by placing a slot across the two probes. The antenna is designed to operate at the frequency of around 2.4 GHz. From the results are shown that, the antenna provides the isolation more than 30 dB and has a moderate gain 8 dBi. The results from this study will...
This research has proposed the enhancement technique of the antenna gain by using a superstrate of metamaterial (MTM). It is deployed with a switchable beam microstrip antenna with double parasitic patches, in which two PIN diodes. Simulations and experimental were carried out for the proposed switchable beam microstrip antenna and the proposed antenna with the superstrate of MTM. The simulation and...
In recent years, video streaming services based on the client server (C/S) model have become common. When distributed through these services, video files need to be watermarked with a unique ID to identify clients, so as to deter illegal video capturing. However, the download bandwidth at servers limit the number of clients that can view video files simultaneously. With peer-to-peer (P2P) communication,...
This paper investigates one possible way to reduce the wastage of clean water used in a public toilet. The study focuses on saving clean water from the use of an automatic urinal flushing system in a toilet. The automatic urinal flushing is set with different water flushing duration parameter. This is to find the most satisfied parameter for users while spending clean water as less as possible. In...
At present, the sharing of open data in any city is importance. The shared data, e.g., flood monitoring data, earthquake data, or traffic data, can be used to improve the way of human life. MQTT, the lightweight messaging protocol based on the publish-subscribe concept, is the most popular protocols used to share these data. There are two elements of MQTT messaging for sharing of any data; topic and...
Southeast Asia is one of the most rapidly growing regions in the world with natural and cultural resources. It is important to pass on the cultural knowledge to the next generation. Intangible Cultural Heritage like traditional dances, or folk dance is a valuable cultural knowledge to be maintained and passed on by transferring tacit knowledge, and even explicit knowledge such as books, or video presentations...
This paper presents the parking space sensor system. This system is composed of car sensors, signal light controllers, sensor hubs, and a data processing server. The system uses RS485 as a communication link between controllers while using MQTT protocol to communicate between controllers and the processing server (MQTT broker). By using RS485 and MQTT, this system is scalable and flexible. The experiments...
To reduce the amount of CO2 produced from the personal cars in the world, the parking lot guidance systems are considered to be the solution in shopping malls or department stores in many countries. However, most of the current parking lot systems are located in the parking area of each shopping mall and they cannot show the parking lots information for the driver that are driving on the road. So,...
