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.

The DLS565 is a Phase-locked loop (PLL) Integrated Circuit (IC) design project simulated on all process corner libraries (TT, FF, SS, FS, SF) using 0.5um CMOS technology. The final IC design layout of the PLL without bonding pads covers approximately 0.46mm × 0.5mm. The parameters of the DLS565 were measured and compared to the commercially available LM565C and NE565. It operates with a supply voltage of ±2.5 V with a maximum power dissipation of approximately 22 mW. DLS565 was able to capture frequencies as low as 15Hz and as high as 1.12MHz.

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.

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.

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.

A low-cost wireless glove controller that detects finger gestures was developed using makeshift flex sensors and a digital accelerometer. The performance of the makeshift flex sensors was compared to that of commercially available ones. A system using Arduino, Bluetooth, and Processing was developed to allow the user to specify desired finger gestures for controlling a variety of robotic devices. A simple mobile robot (mobot) was used to demonstrate the capabilities of the glove in controlling devices. A 3D virtual environment was also created for the virtualization of the user's hand movements detected by the glove controller. Inside this virtual environment, the user-defined finger gestures also allowed the user to control elements inside the virtual environment which can branch out to various applications including rehabilitation and body-oriented gaming.

An 18-bit decimator design for sigma-delta analog to digital converter with variable oversampling rate for audio application was successfully implemented in TSMC 0.13 um Logic CMOS Technology. Behavioral model of this project is implemented using MATLAB and actual implementation using RTL Code with the aid of Verilog Compiler Simulator. The oversampling rates used in this decimator design are 32, 64, 128 and 256. Also, this decimator uses 1 sinc filter and 2 halfband filters as the main blocks for the whole system. The result of the design actually minimized the delay of the signal as compared to the behavioral simulation obtained. The total cell area is reduced reaching the desirable signal-to-noise ratio.

In the business of selling mobile phones the number of units in the inventory and the specification of the components of the mobile phone play an important role in the success of the business. Ideally, it is good for the mobile phone shops to display different models in their stores and have stocks of these models in order to attract customers. However, the problem in that concept is stocking inventory will cost a lot of money. Mobile phone stores often have limited resources so it is ideal to balance the quantity and specification of their units. Given the budget constraint, the specifications of the parts of the mobile phones that will be purchased have to be optimized. The owners of mobile phone stores often do it manually and without scientific basis which lead to inefficiency. This research shows a scientific approach in minimizing the average annual cost of ordering and storing mobile phone sets. This is done by using Particle Swarm Optimization in purchasing the number of units and the specifications of their components.
