Effective in-vehicle icons are used to convey quick and complete understanding of information to drivers for safe driving; however, misunderstood icons may result to worse. Former studies were able to point out the ineffectiveness (in terms of matching accuracy) of non-ISO vehicle icons. This study was conducted to fill in the gap in literature that addresses the need for redesigning ineffective non-ISO icons for improvement in terms of the said performance measure. Subjective rating in terms of familiarity, concreteness, complexity, and semantic distance of the icons was also evaluated to get an explanation on their objective performance. 20 non-ISO icons were screened from a particular vehicle model in the Philippines and were evaluated using a matching accuracy test that was programmed for easy facilitation of the evaluation and were answered by 98 respondents (50% Novice and 50% Expert drivers). Of these, 6 icons performed below the ISO standard of 66.7% matching accuracy. These underperforming icons were redesigned using guidelines and suggestions from related literature. This study was able to produce significant improvements both in the matching accuracy and subjective rating of the underperforming icons. Driving proficiency, familiarity, concreteness, and semantic distance were identified to be significant factors that affect the matching accuracy of the test subjects.

The study covered a drug driver system that can be used for continuous glucose monitoring system intended to drive a pump that will administer insulin for the purpose of combating diabetes. The system begins with a microcontroller unit having an analog voltage input that is derived from a calibrated linearity curve relative to that of glucose concentration, the microcontroller algorithm processes the data and determines whether an output of insulin or glucagon is needed. The output of the microcontroller unit is a time variable pulse which is dependent on the glucose concentration reading. Separately, a full custom IC design is conducted for an actual drug driver circuit for the purpose of miniaturization to make the system viable for implantation. The hardware test for the microcontroller unit indicates that the algorithm can be used to properly read glucose concentrations and provide an output accordingly. However, there are delays within the microcontroller which affect the response of the output. For the full custom IC design of the drug driver circuit, it is observed that the parasitic capacitances and resistances affect the propagation delay and power dissipation of the circuit but can still be used in a drug driver system.

One of the trademark behaviors of a swarm is aggregation. Aggregation is the ability to gather swarm members around a specific point in space. The goal is to keep an object, stationary or moving, at the center of the swarm. This paper presents a novel approach to centroid tracking in robotic swarms. Genetic algorithm is used in quadrotor unmanned aerial vehicles to keep the object being tracked at the center while minimizing two parameters: the distance travelled by each quadrotor and the distance of each quadrotor from the object. Centroid tracking was found to have an average error of 0.0623568 units for swarm populations ranging from 10 to 100 with the lower swarm populations exhibiting lower errors. Convergence did not exceed the maximum of 23 milliseconds for populations less than 30. These results show that the algorithm is well-suited for implementation in swarms with lower numbers of quadrotors.

Presently, traffic is a serious problem in Epifanio Delos Santos Avenue (EDSA) cause by increasing work force and increasing number of vehicles [1]. Manual scheduling of buses became inefficient and this was proven by the unbalance number of bus and overcrowded passengers in different points of service, it also affect the bus carrier's profit. This research aims to model a new way of schedule pattern for public utility buses that will maximize the carrier's profit while minimizing the travelling time and congestion in different bus stops. The proposed unification of buses includes the following route, Malanday to Baclaran, Letre to Baclaran, Navotas to Baclaran, and vice versa resulting to the creation of new bus route (Monumento to Magallanes). The proposed new bus schedule was created based on the genetic algorithm that will maximize the bus carrier's profit at the same time minimizing the congestion of public utility buses (PUBs) in EDSA.

This paper discusses the results of experimental research aimed to investigate the potentials of different types of innovative jacketing materials used to retrofit reinforced concrete columns. Carbon fiber reinforced polymer (CFRP) wraps and fiber-reinforced mortar (FRM) jackets were used as retrofitting materials. Steel fibers, synthetic fibers, and cellulose fibers were added as reinforcement to mortar that is used as retrofitting jacket for reinforced concrete columns. To evaluate the effectiveness of these retrofitting techniques, column specimens were prepared and tested. The test results of 9 column specimens with synthetic and cellulose fiber-reinforced mortar jackets, 12 columns with steel fiber-reinforced mortar jackets with 3 different volume fractions (1%, 2%, 3%), and 9 columns retrofitted with CFRP wraps were investigated. The column specimens had square sections with 4-10mm diameter steel as main bars. The dimensions were limited to the size that can be accommodated for axial testing up to failure using a Universal Testing Machine. The confinement effect was quantified by obtaining the individual contribution of each material that comprised the reinforced concrete column specimen and subtracting them from the actual load being resisted. This was done by monitoring the strains of the steel and concrete and relating the measured values to the stress-strain relationships of the materials. The percentage of the confinement effect was obtained in order to evaluate the effectiveness of the contribution of the different materials used in retrofitting techniques. The paper presents the results of the experimental program including the corresponding analysis and comparison of the effectiveness of the different retrofitting materials.

This paper presents a new method in forecasting Philippine Peso to US Dollar exchange rate. Compared to the conventional way, in which the Philippine Dealing System (PDS), as monitored by the Central Bank, determines the rate by analysing demand and supply, the use of artificial neural network, having consumer price index, inflation rate, lending interest rate and purchasing power of the peso as the inputs is presented in this paper. Though foreign exchange rates vary on a daily basis, the output of this paper is prediction of the average foreign exchange rate every month. Artificial Neural Network serves as a powerful tool in forecasting Philippine Peso to US Dollar exchange rate not requiring expert knowledge in banking and finance thus letting the public gain access to a helpful beacon which is the foreign exchange rate. However, the accuracy of the forecast using artificial neural network is highly dependent on the volume of the training data, in this paper, an alternative algorithm that will increase the accuracy of the conventional artificial neural network with limited volume of training data is presented and analyze.

This paper presents the design and implementation of full-wave AC-DC converter in 0.18 micron CMOS technology. Five sample voltages were taken from vibration electromagnetic harvester technology (VEHT) and simulated in three operating temperatures of 0, 25, and 70 degrees Celsius. The simulation results yielded: a maximum average power efficiency of 95.02% at 0°C 95.61% at 25°C, and 91.05% at 70°C; and an average regulation percentage of 10.45% at 0°C, 24.91% at 25°C, and 10.15% at 70°C.

In this paper, we propose a sympathy expression model for a bystander robot that honors the concept of moral emotion. Therefore, we pay attention to the robot that is in a bystander position, which is unrelated to the communication between participants. We propose a sympathy expression model that lets a bystander robot learn the emotional display of others and enables cooperative expressiveness. This model allows the appropriate expressiveness affecting communication of a robot in the position of a bystander. To test it, we assume the interaction of three robots with the emotion generation model using the neural network. Further, we inspect the movement of this model by using a psychology model. As a result, we confirmed the appropriate actions of this model.

This study describes the application of dipole liquid metal antenna as a possible sensor of crack when embedded in a concrete beam prototype on several locations. The approach to the fabrication of antenna is based on McGyver-esque approach to microfabrication. The antenna consists of Eutectic Gallium Indium (EGaIn), a fluid metal alloy injected into microfluidic channels comprising a silicone elastomer composed of polydimethylsiloxane (PDMS). While the fluidic dipole antennas are highly flexible, stretchable, and reversibly deformable, changing its length through stretching the elastomeric channel also changes its resonant frequency. Experiments show that increasing the length of the antenna (not embedded in concrete), decreases its resonant frequency. This relationship becomes the basis of the study whether the antenna behaves in the same manner when it is already embedded in prototype concrete beams. Simultaneous testing using center-point loading machine and network analyzer for the three embedding locations of antenna are conducted to gather the necessary data that would best adapt to the inverse relationship of antenna's resonant frequency and displacement due to loading.

This paper presents the results of the evaluations conducted on the alternative pathways considered in net energy analysis of Jatropha press-cake utilization as biofuel feedstock. Biogasification and thermal gasification are the two alternative pathways specifically being considered in this particular study. An Energy Return on Investment (EROI) was introduced in this study as the primary tool for net energy analysis respectively. EROI was able to further evaluate the economic variability and potentials of utilizing Jatropha press-cake as the feedstock for generating renewable biofuels. The by-products of the two alternative pathways being evaluated is not yet considered in this study. However it is highly recommended for future research that by-products must be considered in net energy analysis.
