This paper presents the results from the development of a machine to enhance and develop the post-harvest process of Philippine Farming, specifically drying. It aims to help the farmers increase rice yield, productivity and therefore, increase income. The Solar-Powered Paddy Grain Humidifier-Dryer consists of a power supply with two alternating batteries charged with solar panels, a control system to automatically control moisture content, temperature and humidity depending on the desired moisture content of the user, a humidifier and dryer that provides heat and humidity output and a GSM module for updated inventory. The users of the machine (farmers) are guided by a manual that instructs them in layman's term on how to set their desired moisture content by simply pushing a button. This maximizes rice production from 83% to 93% which shortens the processing time by 25-50% compared to traditional ways of drying and existing drying machines that can be used for all seasons. © 2016 IEEE.

As reported by the National Disaster Risk Reduction Coordinating Council of the Philippines, from the year 2010-2015, landslide is the third most recurring geohazard, next to floods and earthquake. Casualties caused by landslide constitute 1.55% of the total casualties during the same time span. Due to fact that a landslide early warning system is not considered, and the practice of only secluding the public from defined landslide prone areas, the safety of the general public is always at risk. The objective of this paper is to develop a landslide early warning system that utilize rain gauge and an intelligent accelerometer/inclinometer for interception of possible occurrence of landslide. With the help of PHIVOLCS and PAGASA calibration for the standard level of measurement were established: (l)rainfall amount,(2) angular displacement and (3)ground movement. With the factors observed it is expected to deliver an effective landslide early warning system that can intercept an impending landslide whether it is earthquake-induced or rain-induced. © 2016 IEEE.

Balikbayan boxes sent by OFW's abroad are delivered by freight forwarders to their rightful recipients. But before arriving at the recipient's residence these packages pass through a series of transfers and transactions (foreign forwarder, shipping company, Bureau of Customs, local forwarder, etc.). In every transaction and transfer, the balikbayan box is vulnerable to different circumstances. The security of the items inside is at stake. I-Box (Innovated Balikbayan box Operation Express) is an innovation to the common delivery system that tracks and monitors the condition of the balikbayan box for secured delivery thus solving the flaws of the normal delivery system. A point to point implementation of this design enhances the monitoring and tracking of the boxes. The realized design uses RFID (Radio Frequency Identification) tags to monitor and track the exact location of the box that is unique to every box making the identification of the box non-reproducible. © 2016 IEEE.

In this paper, we report the first synthesis of hydroxyapatite (HAp) nano-rods derived from mussel shells by a facile sonochemical method. HAp nano-rods were characterized by X-ray diffraction (XRD), Transmission electron microscopy (TEM), and Fourier transform infrared spectroscopy (FT-IR). The photocatalytic activity of HAp nano-rods was investigated using Rhodamine B (RhB) dye for the first time. The results confirm that degradation efficiency of 86.8% for RhB was observed after 300 min in the presence of the HAp nano-rods photocatalyst. © 2017 Elsevier B.V.

Electrochemical scanning tunneling microscopy (EC-STM) was employed to examine the molecular assembly and electropolymerization processes of 3, 4-ethylenedioxythiophene (EDOT) onto reconstructed and unreconstructed Au(1 00) single crystal electrodes in a 0.1 M HClO 4 electrolyte solution. The EDOT adsorption onto the Au(1 00)-hex surface induced lifting of the reconstruction at potentials as low as E = 0.150V (vs. reversible hydrogen electrode (RHE)), which is clear evidence of the strong EDOT-Au interaction that was also observed by cyclic voltammetry (CV). EC-STM was also able to reveal, for the first time, the dynamic process of EDOT molecular self-assembly onto the Au(1 00)-(1 × 1) surface. The EDOT adlayer was found to fit into a 4√2 × 3√2 unit cell. High-resolution STM imaging revealed a vertically tilted geometry for the EDOT molecules. Electropolymerization was also performed, revealing the solution-process formation of polymer bundles. © 2012 Elsevier Ltd. All rights reserved.

An extensive evaluation of capacity interpretation criteria is presented for driven Precast Concrete (PC) piles under axial compression loading. A database of static load tests for round and square cross-section piles under both drained and undrained loading was developed and utilized in the analysis. The compiled data are generalized into four groups (round - drained, square - drained, round - undrained, and square - undrained) to examine the differences in their behavior. Generally, similar trends for each criterion are noted for the four groups. Statistical analyses show a decreasing COV with increasing pile displacement, and the drained load tests show less variability than the undrained load tests. For drained loading, somewhat higher interpreted capacities are exhibited by round piles than by square piles. In addition, a slightly stiffer normalized load-displacement curve is shown for the drained loading compared to the undrained loading. The drained and undrained databases are further sub-divided by hammer type (drop, air/steam, diesel, and hydraulic) to explore the effects of driving energy and driving resistances on pile capacity. Based on these analyses, the relative merits and interrelationships of these criteria are established, and design recommendations for the use of these methods are suggested in terms of normalized capacity and displacement. © 2013 Korean Society of Civil Engineers and Springer-Verlag Berlin Heidelberg.

This study determined the removal of nickel from a synthetic Watts bath electroplating composition (NiCl2·6H2O, NiSO4·6H2O, and H3BO3) by homogeneous fluidized-bed granulation process. The effects of adding calcium ions present in an electroplating bath while varying influent nickel concentration (200 mg·L-1, 300 mg·L-1, and 400 mg·L-1), [CO3 2-:Ni2+] molar ratio (1.0, 1.5 and 2.0) and pH of carbonate precipitant (10.5, 10.8, and 11.0) were evaluated. Calcium ion addition was varied at 20 mg·L-1, 50 mg·L-1, and 100 mg·L-1. The best operating conditions were at 300 mg·L-1 influent nickel concentration, [CO3 2-:Ni2+] molar ratio of 1.5, and pH of 10.8 of the precipitant from different types of water source. The removal of nickel from synthetic Watts bath electroplating wastewater using tapwater was 84.93%, and 92.66% with the addition of Ca2 + ion at 20 mg·L-1. For the synthetic Watts bath electroplating wastewater using reverse osmosis water, nickel removal was 97.08% and 98.51% when pure nickel ion in the solution was used. The characterized granules has low symmetry that confirmed the characteristics of a nullaginite mineral of Ni2(CO3)(OH)2. © 2016 Elsevier B.V. All rights reserved.

This security system provides a cost-efficient alternative solution to intelligent security systems by using a standard webcam, personal computer, and a PIC microcontroller. This system uses a program developed in NI-LabVIEW which uses image processing. The said program only records the camera input once motion is detected, which reduces the duration of the video footage, disk space needed, as well as the time taken to review the recording. Furthermore, the camera continuously pans the area by using a PIC microcontroller and a servo motor. This feature allows the camera to cover areas outside its regular field-of-view. © 2015 IEEE.

The Direct Selling Industry in the Philippines is continuously growing as more people become direct sellers. With this, the ability of direct selling companies to manage its sellers will be a challenge. Customer Lifetime Value (CLV), or the monetary value a customer is expected to contribute to the company before churning, is one measure that can be used as a basis for managing customers and for this matter, the computation of the CLV must be accurate enough to be used effectively. However, CLV computation that is specific only for direct selling companies is not yet established. This research used Data Mining Techniques, specifically Binomial Logistic Regression Analysis and Multilayer Perceptron Neural Network to develop a model that can predict CLV based on historical customer's transaction and demographic data. Through Binomial Logistic Regression Analysis, the direct seller's average Service Lifetime was found to be 12 years and the significant factors that affects customer churn was determined as well. Through Multiple Linear Regression Analysis the significant factors that affect customer profit contribution was identified. Markov Chain Analysis was then used to establish possible customer states and a state transition probability matrix. Finally, Multilayer Perceptron Neural Network with 1 hidden layer was used to establish a neural network predictive model. The results are used to develop the final model, which was based on the Present Worth formula. The resulting model has a hold out relative error of 0.018, which indicates a good predictive accuracy of the equation. The model can be used by direct selling companies to help them manage their customers more effectively. © 2016 IEEE.

With oil being a non-renewable energy, buyers of aviation fuel are more inclined to purchase Jet-A1 from oil companies that offer the best jet fuel. But the fact of the matter is that, aviation fuel has the same content even when you purchase it from halfway across the world. Although price is an apparent factor that airlines consider when deciding which oil company to choose for as a supplier, there are ambiguous factors that needs to be established so that continuous product development can be made by the aviation fuel organizations. This study used conjoint analysis as a tool to establish the attributes considered by airlines in deciding which oil company will best meet their needs. As a result, the following six attributes of aviation fuel were identified: availability, price, accessibility, manpower, equipment and facilities, and fuel quality and safety. The results indicate that fuel quality has the greatest influence on the respondents' purchasing intentions, followed by price, availability, equipment and facilities, and accessibility. Manpower was the least important attribute with regard to the airlines' buying intention. Based on the results from data analysis, it is concluded that conjoint analysis is an appropriate tool to identify the key attributes of aviation fuel. Using the results presented in this study, aviation fuel companies can better tailor their fuel services to meet the needs of the airlines and thus increase sales. © 2016 IEEE.
