DETECTION SYSTEM OF ELECTRICITY THEFT AT SERVICE CONDUCTORS OF ELEVATED METERING CENTERS

In the Philippines, one of the solutions to energy theft from utilities involves the relocation of electric meters to elevated metering centers, away from the residential building. The length of the service conductorshad made it vulnerable to illegal connections. The proposed solution is a system with theft recognition and magnitude determination mechanisms. The two mechanisms work based on voltage and energyreadings. The system was designed and tested using a residential building-rated microcontroller-based prototype utilizing an energy monitor as input device and the ZigBeeprotocol for wireless communication. The sensitivity, specificity, and success rate of the recognition mechanism were all 100 percent. The percent error of the theft magnitude determination mechanism ranged from 0 to 2.17 percent. Through cost-benefit analysis, the system was found to have positive net benefit at theft probabilities higher than 3.94 percent. The system has excellent usability as assessed though System Usability Scale.

V-TROUGH REFLECTORS USING OPEN-LOOP SINGLE AXIS SOLAR TRACKING FOR A PV MODULE

Because of its geographical advantage, the Philippines is one of the countries with the highest potential in solar energy harnessing. At present, the solar industry utilizes solar trackers for large scale applications but not in small scale due to their uneconomical prices relative to the financial capability of consumers. Thus, small scale applications only make use of static solar panels. This study intends to link the gap between the presently available technology to small-scale consumers and the integration of both solar tracking and concentrating photovoltaics (CPVs) into a PV module to harness more power. V-trough solar reflectors were programmed to follow the sun based on algorithms set by NREL. A bypass mechanism was also included to protect the system from detrimental temperature levels. The device was tested based on the accuracy of the reflector inclination angles, significance of the increase in the output power and the cost-benefit analysis based on consumer perspective. The error in the inclination angles were found to be minimal, the increase in power output was significant and the device has an annual return of investment of 17.04% within a payback period of 5.83 years.

COMPARISON OF STRUCTURAL DESIGNS OF A LOW-RISE BUILDING USING NSCP 2010 VERSUS USING NSCP 2015

The study compared the structural designs of a standard three-storey building in Apayao using the NSCP 2010 versus using the NSCP 2015. The existing plans of the building were used for the design of the building model. Dead loads, live loads, wind loads, and earthquake loads were the loads needed to be compared in the study. The data from these loads were simulated using STAAD and ETABS. Design adjustments were made during and after obtaining the output. The final analysis and evaluation were made using different parameters such as stresses, moment diagrams, shear reinforcements, and areas of steel reinforcements.

ANALYSIS OF THE STRENGTH OF BAMBOO REINFORCED PLASTIC BOTTLE CONCRETE BEAMS FOR LOW-COST HOUSING

The world consumes about a million plastic bottles a minute, with the Philippines as one of the top plastic polluters. It is currently one of the many crises that the Philippines is experiencing. Using plastic bottles in designing a reinforced concrete beam is one of the many examples in the modernization of sustainable structures. An alternative for traditional construction materials is the key point, thus, this study incorporated the use of bamboo fibers as reinforcement in replacement of steel which is known for its high cost. Bamboo is known for its low-cost, wide availability and it is well known for its diverse properties. This research intends to investigate the flexural capacity of bamboo reinforced plastic bottle concrete beams for low-cost housing, determine the potential of this model in the field of construction, and analyze its effect on cost.

SMART ADAPTOR: A WIRELESS POWER SWITCH OF HOME APPLIANCES FOR RISK REDUCTION

As the technology invades our homes, the chance of electrical fires happening increased over recent years. The study, Smart Adaptor is the solution suited in preventing those fires with simple home automation using smart adaptor system which transforms traditional appliances at home into a smart one. It was focused on creating a device to be added to the home appliances that is efficient, reliable and accurate and helped on lessening fire breakouts due to electronic malfunction. The device was tested in two households in Brgy. 150 Tondo, Manila wherein the device was used in two weeks span. The three main components were examined wherein the PIR sensors ability to detect human presence, the smart adaptors capability of turning off appliances and the Main servers monitoring skill were tested. The efficiency was based on the power consumption in two households wherein a decrease of 20-28% in the total power consumption with Smart Adaptor was measured. The average response time of 0.95 seconds proved the reliability of the PIR sensor to detect human presence within the range of 105o within 5.4 meters distance and 2.74 meters width. The connectivity of the PIR and main server had an accuracy of 90% while that of the smart adaptor to the main server was 85%. Hence, the three main components in a system were acceptable to the respondents with 4.35 overall rating. Thus, the system was capable of monitoring home appliances and reduces fire breakouts at the same time.

University Students’ Virtual Experiences in the Civic Welfare Training Service (CWTS) Course

As the World Wide Web (WWW) develops prominence through the years, it has become a powerful and useful instructional medium (Robertson, Grant, & Jackson, 2005; Oliver, Herrington & Omari, 1996). As the new language of instruction, it provides easy access to information, flexible storage, display options and publications. Through its search engines, users are given a wide range of opportunities to join forums, read and post messages, prepare and present multimedia reports, and take quizzes via email (Oakes, 1997), among others. Moreover, students with previous experience in distance learning felt more comfortable in the use of computers, thus providing them with a more egalitarian learning environment. Such an environment has encouraged students to think independently without struggling to learn at their own pace.

SMS BASED ELECTION SOFTWARE

This study aims to find a solution to the perennial problem of inefficient and costly conduct of elections in the Philippines. It proposes the use of the SMS-Based Election software run by a computer program linked to a designated server, computers, and cell phones. It is assumed that the use of this program will significantly reduce the time to conduct and determine the results of elections. In addition, it will reduce the cost of the conduct of elections and this will mean savings for the government. The program was pilot tested in a school election. Using triangulation, the results were generated less than an hour after the voting and were found to be 100% accurate. A focused group discussion with the student voters later confirmed that the results matched the names of the candidates for whom they actually voted. The research concluded therefore that the program is not only efficient, but also 100% accurate.

INTERNET – BASED CAR COLLISION VERIFICATION SYSTEM FOR CAR INSURANCE COMPANIES

The study has focused in the development of a product that could help the insurance company to verify if their policyholder has encountered an accident or collision. When the car owner encounters an accident or collision it will notify the insurance company via web by sending the pictures of collision and the details of the vehicle, this serves a supporting tool for the insurance policy holder whenever they encountered an accident or collision. The method used for the development of the project is the agile development method. Agile development method attempts to develop a system incrementally, it emphasizes continuous feedback. The hardware materials that were used in this project are the single board which is the raspberry pi, collision sensors that detects the collision, cameras that captures the images when there is an impact detected. The raspberry pi will send the information such as the location of the accident or collision using the GPS, vehicle’s plate number and the owner’s name via web. A text message will be received by the policyholder when the information is receive in the insurance company’s web site. And the insurance company can manage the status of the policyholder’s claim.
