Philippine Carabao Mango Pest Identification Using Convolutional Neural Network INTERNATIONAL JOURNAL OF SCIENTIFIC & TECHNOLOGY RESEARCH VOLUME 9, ISSUE 03, MARCH 2020 ISSN 2277-8616 Philippine Carabao Mango Pest Identification Using Convolutional Neural Network Antonio V. Rocha IV, Joe G. Lagarteja Abstract— The detection and management control of pests in mangoes if applied properly would result to a higher fruit production. Applying precision agriculture with the use of modern technology helps mango farmers detect and identify the different types of pests that are infesting their farms. This research study introduces a computer application development that can identify and determine mango pests based on the provided images using a smartphone. Convolutional Neural Network (CNN) is a type of algorithm that was used to train stack of mango pest images which were pre-processed and used as a train model. Using Convolutional Neural Network (CNN), the images were processed to determine the type of pests currently present on mango trees and provides the best control measure that the system would provide after detection. The neural network was designed using Keras to run on top of the deep learning framework TensorFlow. Datasets composed of 4,300 images were used for training and 800 were used to validate the CNN model. The model achieved a remarkable 88.75% accuracy rate in determining mango pests. GIS (Geographical Information Systems) was also utilized to determine affected areas in the region.

Commercial sources of CaC2 may be contaminated with arsenic and phosphorous, which are also released during a chemical reaction. This constitutes a potentially serious health risk to ripeners and may contaminate the product. Although banned in many countries, CaC2 is still used in the Philippines because equally inexpensive and effective alternatives are lacking. This study investigated the relative efficacy of alternatives for ripening ‘Carabao’ mango. Fruit harvested at –1 107 d after flower induction were treated with CaC2 (2.5, 5.0, or 7.5 g kg ); ethephon (500, 1000, or 1500 μL L–1); Gliricidia sepium leaves (20% w/w); or ‘Cardava’ banana fruit (10% w/w) for 72 h. Mangoes were then held under ambient room conditions [29.9 ± 3.1°C, 77.74 ± 2.9% relative humidity (RH)] for 7 d. Assessments of peel color, firmness, and total soluble solids showed that fruit treated with higher concentrations of ethephon (1000 or 1500 μL L–1) exhibited similar ripening –1 responses as those treated with CaC2.

  • The AQUINO MANAGEMENT of the PRESIDENCY
    The AQUINO MANAGEMENT Of The PRESIDENCY \ ONE WITH HER PEOPLE Published by the Presidential Management Staff Office of the President Manila, Philippines June 1992 “The politics of the present and the future is a people politics, just like the character of the revolution that brought us all here was people powered. In the same manner, the full recovery of this country and the fulfillment of this potential must be an affair of the people, and for the people. There is no other way.” President Corazon C. Aquino Magtanong Sa Pangulo September 16,1988 2 _________________________ INTRODUCTION KEEPING IN TOUCH with her people was an activity that President Aquino relentlessly pursued. To her, it was not a job; it was a source of joy, inspiration, and wisdom. One of the activities which kept President Aquino in constant touch with the people was her trips to the barrios. To those who had been used to the grandiose schemes of the past regime, President Aquino’s trips were non-events. But these regular visits assumed an informal and festive air as she talked with the rural folk. Here, without the trappings of protocol and critical eyes, President Aquino became animated and relaxed. She literally sat down with the common tao and with the local leaders – from the lowliest kagawad to the most charismatic provincial governor. To the President, this open link energized her government. Where others relied and flaunted surveys, President Aquino’s most accurate and most dependable gauge on the public pulse were her frequent one-on-one with the people from the countryside.

Diane Barnes, Thesis Advisor Date Dr. David Simonelli, Committee Member Date Dr. Helene Sinnreich, Committee Member Date Dr. Salvatore A. Sanders, Dean of Graduate Studies Date ABSTRACT Filipino culture was founded through the amalgamation of many ethnic and cultural influences, such as centuries of Spanish colonization and the immigration of surrounding Asiatic groups as well as the long nineteenth century’s Race of Nations. However, the events of 1898 to 1914 brought a sense of national unity throughout the seven thousand islands that made the Philippine archipelago. The Philippine-American War followed by United States occupation, with the massive domestic support on the ideals of Manifest Destiny, introduced the notion of distinct racial ethnicities and cemented the birth of one national Philippine identity. The exploration on the Philippine American War and United States occupation resulted in distinguishing the three different analyses of identity each influenced by events from 1898 to 1914: 1) The identity of Filipinos through the eyes of U.S., an orientalist study of the “us” versus “them” heavily influenced by U.S.

  • A Brief Syntactic Typology of Philippine Languages
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by ScholarSpace at University of Hawai'i at Manoa A Brief Syntactic Typology of Philippine Languages Lawrence A. Reid & Hsiu-chuan Liao University of Hawai‘i This paper is a brief statement of the typological characteristics of the syntactic structures of Philippine languages. It utilizes a lexicalist theoretical framework to provide comparability among the examples cited. The word order of both verbal and non-verbal predicational sentences is examined, with pronominal and non- pronominal complements, topicalization, and auxiliary verbs. Philippine languages are analyzed as morphologically ergative. The morphological criteria for determining the syntactic transitivity of verbal sentences is examined, concluding that verbal affixation alone is an insufficient criterion. Attention is paid to the notion of “focus”, with rejection of the concept of “voice” as an explanation for the phenomenon. The various forms of syntactically transitive verbs that have been described by others, for example, as signaling agreement with the Nominative NP, are here described as carrying semantic features, marking the manner of their instantiation with reference to the Nominative NP. The structure of noun phrases is examined. Morphological case marking of NPs by Determiners is claimed for Genitive, Locative, and for some languages, Oblique NPs, but it is claimed that for most languages, Nominative full NPs are case marked only by word order. Semantic agreement features distinguishing forms of Determiners for common vs. personal, definiteness, specificity, spatial reference, and plurality of their head nouns are described. Relative clause formation strategies are described. Most are head-initial, with gapping of the Nominative NP.

  • Background the Philippines Is an Archipelago (Chain of Islands) Comprised of Over 7,100 Islands in the Western Pacific Ocean. Or
    Beatriz Dykes, PhD, RD, LD, FADA Background The Philippines is an archipelago (chain of islands) comprised of over 7,100 islands in the western Pacific Ocean. Originally inhabited by indigenous tribes such as the Negroid Aetas and the pro-Malays. Beginning in 300 BC up to 1500 AD, massive waves of Malays (from Malaysia, Sumatra, Singapore, Brunei, Burma, and Thailand) immigrated to the islands. Arab, Hindu and Chinese trading also led to permanent settlements during by these different groups during this period. In 1521, Spain colonized the Philippines, naming it after King Phillip II and bringing Christianity with them. The Spanish colonization which lasted 350 years, imparted a sense of identification with Western culture that formed an enduring part of the Philippine consciousness, unmatched anywhere else in Asia. The prevalence of Spanish names to this day (common first names like Ana, Beatriz, Consuelo, Maria and last names as Gonzales, Reyes, and Santos) reflects this long-standing influence of the Spanish culture. The United States acquired the Philippines from Spain for 20 million dollars after winning the Spanish-American war through the Treaty of Paris in 1898, introducing public education for the first time. During this period, health care, sanitation, road building, and a growing economy led to a higher standard of living among Filipinos and the Philippines became the third largest English speaking country in the world. Above all, the US occupation provided a basis for a democratic form of government. World War II had the Filipinos fighting alongside the Americans against the Japanese. The Death March and Corregidor became symbolic of the Philippine alliance with the United States.

By what means the earliest settlers arrived in the archipelago is still a mystery, but a growing body of evidence points to the likelihood that they possessed seafaring technology. If so, then modern Filipinos—who are even now making their first tentative steps into space—are heirs to a rich heritage of exploration, the story of which has yet to be fully told.
