This paper introduces a simulated model of broadband intrabuilding power line noise. We obtained a periodic burst error caused by cyclostationary noise inherent in a typical intrabuilding powerline channel. The simulated model is used to locate erroneous video packets and its periodicity of occurrence. The PSNR quality of decoded video sequence subjected to the noise model is compared with the lossless...
This paper presents the development of a speech-controlled human-computer interface (SR-HCI) as a subsystem of the audio-visual breast self-examination guidance system. This aims to better control the system during computer-guided breast self-examination (BSE) performance and allows for user indications of possible tumor locations by dictating it to the system through the speech recognition feature...
Various cities in the Philippines have started to prohibit the use of plastic bags and packaging materials in favor of paper products for waste disposal and management reasons. This study evaluated the soundness of these initiatives based on life-cycle analysis (LCA) framework. While a number of studies have looked at similar issues in other countries, results may not be entirely valid in the Philippines...
In preliminary sizing, wing loading, power loading, and maximum lift coefficient are commonly determined through an informal optimization process using statistical equations based on existing aircraft data in conjunction with a matching chart from which the best design point is picked. Presented here is an alternative method where these pivotal design parameters are computed using non-statistical...
Self compacting concrete (SSC) is one of the most useful innovations in concrete technology that has the ability to flow efficiently and maintain material homogeneity. However, additives particularly admixtures introduced in the production of SSC to enhance some specific properties of fresh and hardened concrete may contribute undesirable effects on the workability performance. In this study, superplasticizers...
Image stitching is done by combining multiple input images such that the ideal result is a single image that contains contexts from all the inputs as well as seamless transitions between contexts. It is most commonly used in the field of panoramic photography. Large dissimilarities in the input image set are very problematic in image stitching applications. These cause several objections in the resulting...
This paper presents a machine vision algorithm to detect traffic violations specifically swerving and blocking the pedestrian lane. The proposed solution consists of background difference method, and focuses on the genetic algorithm of the system to detect these violations. The general process is as follows: a capture picture is to be subtracted first by the reference image, then the genetic algorithm...
The present study discussed pertinent design parameters used in designing the yaw brake system of horizontal axis wind turbine. The hydraulic power unit of yaw brake system should be designed properly to control the yaw brake during yaw movement of nacelle and to activate the brake calipers when necessary during turbine operation and maintenance work. System design requirements of hydraulic power...
This paper presents the artificial neural network model for the transportation system in Epifanio Delos Santos Avenue. Intelligent transportation aims to optimize the transportation system in Metro Manila. It will enhance productivity among public commuter and bus companies. The goal of this model is create an effective bus scheduling and dispatch system. This scheme will result in shorter waiting...
Epifanio de los Santos Avenue (EDSA) is one of the busiest national road in the Philippines millions vehicle are passing thru it every day especially in rush hour. Implementing Intelligent Transportation System (ITS) along this high way will provide a big help to every Filipino. This paper applied Artificial Intelligent (AI) and Artificial Neural Networks (ANN) to find the corresponding bus schedule...
Analysis of emotion in speech is manifested by the analysis of the vocal behavior of the nonverbal aspect of the speech. The basic assumption is that there is a set of objectively measurable voice parameters called prosodic aspects of speech, which can be assessed through computerized acoustical analysis. In this paper, we report results on recognizing emotional states (happy, sad, angry) from a corpus...
Wireless Gigabit (WiGig) presents advantages against IEEE 802.11ac's WiFi in 2.4 and 5 GHz such as faster data rates, intermittent connection, and power efficient transmissions in 60GHz band. However, WiGig antennas have a common disadvantage which is complexity with their designs that provides lesser availability of WiGig connection. The study aims to develop an improved gain and beamwidth with less...
This paper presents a digitally controlled closed-loop step-down charge pump converter with fractional conversion ratios, implemented in TSMC 0.18um 1P6M CMOS technology. A simple and area-efficient implementation of charge-pump converter with low ripple output voltage and fast settling time response implementation is achieved. The feedback loop configuration provides the circuit load protection from...
Refractive index is a physical property which can be used in determining the end point of transesterification in producing biodiesel. The traditional method in acquiring refractive index measurements takes place outside of a transesterification reactor making remote sensing impossible. In this study, a fiber optic cable was used to identify the appropriate wavelength to acquire the refractive index...
With the increase in energy consumption, the concept of harvesting energy in the surroundings awaken a renewed interest. Scarcity of resources has been a great matter to all and researchers have been innovating new methods in harvesting energy. A power management system (PMS) is needed to manage and maximize the output energy coming from the piezoelectric and solar photovoltaic harvesters. However,...
This paper describes a method of conveying perception information from a self-driving golfcart to nearby pedestrians via a Light-Emitting Diode (LED) strip. By equipping autonomous vehicles (AVs) with this feature, their performance as social robots is improved by building trust and engagement with interacting pedestrians; typical pedestrian-driver acknowledgement is replaced by visual feedback via...
Clothing companies should be aware of the in demand products that they should reproduce at a given time. In this study, the researchers aim to improve monitoring of sales in the business industry specifically in clothing companies. The group implemented a system that automatically scans and records apparel swing tags, which is geared towards an easier and faster processing of sales with the use of...
the need for better and more reliable security measures is prevalent today especially as the commonly existing security measures are getting less reliable. The study was conducted to create a solution to the said problem using the very versatile and relatively inexpensive Field-Programmable Gate Array (FPGA) board. The system incorporates the unique frequency content of every individual as a more...
Mobile devices, with the improving trend of smartphone use, is an area of study for human behavior on wireless data communications systems which serves as the converging focal point. The prediction of user quantities with non-intrusive data gathering in wireless communications trends and the correlation of Wi-Fi characteristics with quantity are important links towards data aggregation technique developments...
