FORENSIC EVALUATION OF TEMPERATURE HISTORY FOR FIRE-DAMAGED CONCRETE USING AN ORDINARY DIGITAL CAMERA: CASE STUDY OF THE BURNED PALMA HALL PAVILION II, UP DILIMAN
Diocel Harold M. Aquino, Benito M. Pacheco and Nicole C. Miranda

Though generally-regarded for its resistance to fire, concrete’s physico-chemical characteristics are also affected when subjected to elevated temperatures. This may pose issues on the integrity of a concrete structure. Changes in the concrete properties are manifested in color changes brought about by chemical reactions that take place in elevated temperatures. The aim of this study is to develop a method for color image analysis using an ordinary digital camera, to enable an easy, quick-to-execute and inexpensive method of evaluating the integrity of a concrete structure exposed to fire without compromising the quality of analysis. The method was tested on samples taken from the burned Palma Hall Pavilion II, UP Diliman. Images were taken and processed for their relative hue values and referenced against existing RHV-temperature curves. It was found that the highly damaged columns sustained up to approximately 550°C and that slightly damaged columns sustained up to possibly 337°C.

MODE CHOICE AND VALUE OF TIME OF INTER-ISLAND TRAVELERS: THE CASE OF THE PHILIPPINES
Dr. Alexis M. Fillone and Krister Ian Daniel Z. Roquel

Effectively managing inter-island travel is critical to the unified economic growth and development of a country, especially for archipelagos like the Philippines, where inter-island travel directly affects the local economy. To efficiently manage a transport network across islands, it is important to understand how the travelling population make their travel mode choices, just as much as the operating characteristics of the transport modes available. This study covers the development of logit choice models, based on revealed preferences of the travelling population across the Panay-Negros islands. Travel mode characteristics like travel time, cost, comfort, as well as socio-demographic information like age and income, are found to be significant in the travel decision. The average value of travel time savings is computed to be at Php87.89/hour ($2.04 /hour). Furthermore, the values of time of different groups based on travel frequency, day of travel, gender, civil status, income class, and trip purpose are also determined. These values can be used in feasibility analysis of various transport infrastructures that may be introduced to the network.

COMPARATIVE DRIVE CYCLE FUEL ECONOMY OF IN-USE PUBLIC UTILITY JEEPNEYS USING 2% AND 5% CME-DIESEL BLENDS
Edwin N. Quiros and Karl B.N. Vergel

This study presents the results of drive cycle tests conducted on in-use public utility jeepneys running on 2% (B2), and 5% (B5) by volume Coconut Methyl Ester (CME)-Diesel blends. The tests measured fuel consumption of sample jeepney units on a chassis dynamometer driven following the European ECE1504 Drive Cycle fueled with B2 and B5 CME-Diesel blends. These tests were part of an overall study examining the effects of B2 and B5 blends on the economic operation and fuel economy, measured on-road and in the laboratory, of jeepneys conducted by the UP National Center for Transportation Studies (UP NCTS) and UP Vehicle Research and Testing Laboratory (VRTL) for the Philippine Coconut Authority (PCA). Data from the study will be used as one of the inputs, among others such as economic, logistics, and fuel quality issues, to deliberations to decide for the introduction of 5% CME-Diesel blend in commercial diesel fuel. The drive cycle tests of seven (7) jeepney units range from about 0.5% to 11% specific fuel consumption (gm/km) improvement for B5 relative to B2 for an overall average SFC improvement of 4.6%. The change in mileage for B5 relative to B2 ranged from -2.40 to +11.91 percent for an overall average of around 3.0%. The mileage results were affected by the observed relative density of B5 with respect to B2 – a less B5 density than B2 adversely affects B5 mileage versus B2. “Mixed” mileage results were observed. The amount of fuel economy change when using B5 compared to B2 in jeepneys is thought to also depend on in-use engine conditions and drivetrain configuration. While the observed overall better fuel economy of B5 relative to B2 tends to favor a shift to B5 diesel blend implementation, the authors recommend further detailed studies on CME-diesel blend effects on engine/vehicle performance and emissions for a more sound technical basis for policy decisions.

INFLUENCE OF POROSITY, DEGREE OF HYDRATION, AND EFFECT OF TEMPERATURE ON COMPRESSIVE STRENGTH OF OPC PASTE
Rodrigo V. Dejeto and Kiyofumi Kurumisawa

Ordinary Portland cement (OPC) is used worldwide as basic construction material. Studying its physical, chemical and microstructural properties is important. In this study, the influence of porosity, degree of hydration and the effect of temperature on the strength of Japan OPC were evaluated using the water/cement ratio (w/c) of 0.40 and intensive procedures in sample preparation and testing. High early compressive strength development, fast degree of hydration and decreased porosity were observed in 3-day cement cured at 40oC. However, the strength and degree of hydration begun to decline after 28 days of curing period which was nearly com-parable to cement cured at room temperature.

BREWERY HEAT EXCHANGER NETWORKS DESIGN AND OPTIMIZATION BASED ON PINCH ANALYSIS AT A SINGLE ΔTMIN

Leni C. Ebrada, Mark Daniel G. de Luna, Ferdinand G. Manegdeg and Nurak Grisdanurak

Pinch analysis was applied to design and optimize at a single ΔTmin of 10 oC, a heat exchanger network for maximum energy recovery to reduce the energy consumption of a brewery. At ΔTmin of 10 oC, the minimum heating and cooling requirements of the brewery were 5,185 kW and 3,039 kW, respectively. Above pinch, 120 possible design configurations were identified but only 8 are feasible. Below pinch, only 7 design configurations are feasible out of 52 possible. The optimum heat exchanger network obtained for the brewery is 1 process-to-process heat exchanger and 8 process-to-utility heat exchangers as a consequence of combining the configurations of the least cost feasible designs for both above and below pinch. The optimum heat exchanger network corresponds to a maximum of 22% heat recovery potential which accounts to 4.5% less than the existing operating cost equivalent to $432,133 per year at total annualized cost. Other values of ΔTmin are recommended to be considered for future studies.

APPLICABILITY AND IMPLICATIONS OF THE USE OF REAL TIME KINEMATIC GNSS FOR PROPERTY SURVEYS IN THE PHILIPPINES
Louie P. Balicanta

Property Survey is the use of surveying techniques and procedures to obtain the location, size and shape of a land parcel that is owned or claimed by individual or group entities. It is both technical and legal in nature. Real Time Kinematic (RTK) Global Navigation Satellite System (GNSS) method is the use of dual-frequency GNSS to obtain the position of an object/ entity in real time. Presently, this is widely used in the conduct of surveying tasks such as topographic surveys and stake-out activities in construction surveying. Its use in property survey is not a straightforward application and must consider different situations, problems and limitations. Factors to consider includes coordinate systems used in the country, concepts of common point, azimuths and distances, and limitations such as multipath and obstructions. Methodologies and tests include azimuth determination, survey under tree canopy and use for old and new surveys. The results of the experiments show that RTK-GNSS is applicable for parcel corner position determination with consideration to limitations such as obstructions, level of accuracy, systematic error from projection, different coordinate systems used in the country and poor identification of common points.

PRICE MODELING OF THE NON-LOAD BEARING CONCRETE HOLLOW BLOCKS (CHBS) MANUFACTURED IN ILOCOS SUR
Norma A. Esguerra and Franklin Amistad

In this study, non-load bearing CHBs were bought as samples from sixteen (16) towns chosen at random from manufacturers, eight (8) of which were selected from the First District and another eight (8) from the Second District of Ilocos Sur. The findings are: the samples were smaller than the recommended standard; from the variables compared, only the thickness and strength parameters were significant in influencing the price of the commodity being studied; the strength of the samples were lower than the minimum specified strength of 2.07MPa; no significant difference between and among the sizes, strengths and distance of the quarry site from the place of production exist; CHBs are more frequently sold on delivery mode; and strength and price have significant relationship.

A linear mathematical model, Y =3.836+0.748fc’+0.92t was developed to calculate the price of concrete hollow blocks resulting from a regression analysis, where: Y is the delivery price of the CHB, fc’ is the compressive strength of the CHB produced, t is the thickness.

In conclusion, CHB manufacturers set a uniform price for their products to be competitive, without considering the quarry site distance and strength. Only 41.1% of the variance were identified in this study.

Future researches may explore the remaining 58.9% of the variance for a rational pricing of CHB products; adherence by manufacturers to the prescribed sizes and strength of CHBs and more strict monitoring by concerned agency to the identified concerns be addressed.

ACADEMIC BUILDING ENERGY CONSERVATION OPPORTUNITIES
Ferdinand G. Manegdeg

A framework for determining academic building energy consumption was developed, energy audits on selected academic buildings at the University of the Philippines Diliman were conducted, the different influencing factors to electricity consumption were identified, and energy policy options to ensure effective energy management in the next 5 years are suggested. The electricity consumption is primarily due to air-conditioning and lighting loads or data processing. The energy intensity for lecture rooms, conference rooms, libraries, administration offices and auditoriums were established. Policies for future and existing buildings were formulated. It is recommended that a thorough profiling of student usage and technical usage of laboratories be conducted.

NUMERICAL ANALYSIS OF A SOLAR CHIMNEY

Juvy A. Balbarona

Passive ventilation is among the widely used means of reducing power consumption in residential as well as commercial establishments because of its cost and energy effectiveness. One method of passive cooling that has been around for many years is the use of solar chimneys.  Solar chimney is essentially a thermosyphon utilizing the energy from the sun. The energy coming from the sun heats up the air occupying the chimney cavity to create stack effect that in turn provides natural ventilation. In this study, two-dimensional numerical analysis of a vertical solar chimney is performed to determine the effect of air gap on air flow rate at a given range of solar radiation intensity of 200W/m2 to 400 W/m2. RNG k-epsilon turbulence model used was validated by comparing the results to experimental data, and is found to have good agreement with experiment data for air gap of 0.4. Equivalent air changes per hour (ACH) is then computed for a 59.27 m3 container house to be 5.4 for the vertical solar chimney model, with a chimney gap of 0.4 m at solar radiation intensity of 400 W/m2.

HAZE OPTIMIZED TRANSFORM ON LANDSAT 8 IMAGERY FOR THIN CLOUD DETECTION AND REMOVAL

Mark Edwin A. Tupas

Landsat images, being optically captured, contain one of the most fundamental remote sensing issues– cloud and haze contamination. Various algorithms have been developed through the years to correct haze contamination and maximize the use of archived Landsat images since its launch in 1972. One such algorithm is the Haze Optimized Transform (HOT). HOT identifies spatially varying haze thickness on the premise that clear sky conditions can be characterized from the regression of highly correlated blue and red bands; and features diverging from this relation indicate thickness of haze using their orthogonal distance (HOT values) from clear sky function. A modified Dark Object Subtraction is then performed based on histogram matching per HOT value versus the clear sky case.

This paper presents modifications in applying the HOT algorithm considering the effects of increased radiometric resolution and new coastal blue band in Landsat 8 were tested on two separate images with different dates of acquisition from a test site in the Davao Oriental province of southern Philippines, which was selected due to its prevalent cloud cover condition throughout the year. The effects of the increased radiometric resolution and new coastal blue band in Landsat 8 were tested on two separate images with different dates of acquisition. Haze correction using the coastal blue band demonstrates noticeable difference in adjustment for certain land cover types. On the other hand, the increase in radiometric resolution shows exponential effects to HOT value ranges which translates to finer haze depth estimation but at the expense of performance. Moreover, applying the algorithm demonstrates a higher rate of over correction, which is then compensated by applying a clear aerosols fraction adjustment.

The corrected images are then further processed to compute Normalized Difference Vegetation Index and Supervised Classification to show the effectiveness of the HOT correction algorithm. This study shows that the HOT algorithm with the presented modifications can be efficiently and effectively implemented on Landsat 8 images, and obtain the desired results.

APPLICATION OF A KNOWLEDGE-BASED EXPERT SYSTEM FOR INTERSECTION IMPROVEMENT
Mark P. De Guzman and Ricardo G. Sigua

The KBES developed is a menu-driven type using open source programs with three very important web development tools: The Apache for web server, MySQL for database management, and PHP (Hypertext Preprocessor) for scripting “C” program language. The system guides the user in selecting exact location of congestion or road crash prone areas through an interface. The user deals with series of questions in identifying the cause of the problem which leads to potential traffic control alternative solutions. The KBES was tested at two local isolated intersections in Quezon City, Philippines for validation. The intersections validated are signalized and unsignalized three-legged intersections. The KBES recommendation for the signalized intersection is to increase right turning radius of the corner pavement for trucks to avoid conflict and delay with other vehicles. For the unsignalized intersection, KBES recommended a left turn prohibition at major approach to avoid delay and collisions at such approach.

TRANSPORT OF METHYLENE BLUE THROUGH AN ORGANIC POROUS COCO PEAT MEDIUM COLUMN

Arthur Gonzales III

Industries such as textile and paper that use dyes to color their final product discharge substantial volumes of highly colored water into natural water bodies. Understanding the mechanisms of dye removal from wastewater before discharge to surface waters is important since dyes may disrupt biological processes in the water environment. In this study, the feasibility of using coco peat in removal of methylene blue is demonstrated. A mathematical model describing the chemical transport and removal of Methylene Blue (MB) onto a highly organic biosorbent coco peat was solved in MATLAB using a semi-discrete finite difference with fourth order upwind differentiation. The needed parameters on adsorption of MB onto a biosorbent coco peat were obtained using batch experiment. The batch experiment indicated coco peat is a very good adsorbent of MB with a removal efficiency of 99.61%. It was also shown that the adsorption at equilibrium obeys the Langmuir isotherm with parameters such as maximum adsorption capacity, qm, and the Langmuir coefficient, KL determined for all the temperatures investigated. A column experiment was carried out to obtain effluent breakthrough curves used for calibrating the mathematical model. A linear driving force coupled with solid diffusion model was applied successfully to the experimental data to determine the three major transport parameters, axial dispersion coefficient, DL, external mass transfer coefficient, kf , and solid diffusivity, Ds . The model was tested and fitted well on one experimental case with DL = 1.1304E-05 m2 s-1, kf = 3.6399E-04 m s-1, Ds = 3.34871E-08 m2 s-1 (RMSE = 0.0009). The results also show that the breakthrough curves are dependent on DL and external kf , but not on Ds.

IMPROVING THE MINAHANG BAYAN DECLARATION PROCESS: A FIRST STEP TOWARDS ACHIEVING SUSTAINABILITY IN PHILIPPINE SMALL-SCALE GOLD MINING INDUSTRY
Erickson L. Llaguno, Virginia J. Soriano and Mili-Ann M. Tamayao

Small-scale gold mining contributes significantly to the total value of gold mined in the country surpassing even that of large-scale mining in recent years. With the attendant adverse environmental and social problems that this predominantly illegal operation also generates, the quest for sustainable small-scale mining has long been a concern for the government and other industry stakeholders. The introduction of Minahang Bayan or sites onshore, which is a regulatory mechanism that determines where small-scale mining operations are allowed, is viewed as a means to address this sustainability concern. It is the first step towards legalizing small-scale mining operations as mandated in Republic Act No. 7076, otherwise known as the “People’s Small-Scale Mining Act of 1991”. As of December 2015 however, only three (3) Minahang Bayan have been declared since the law took effect in 1991.

This study shows that the Minahang Bayan policy and implementation is fraught with several fundamental problems: 1) there are no commitments on processing times for several major steps; 2) policy is silent on actions to be taken in case of process delays; 3) the application process is open to a lot of delays; 4)  petitioners and process owners are not very knowledgeable of the process; 5) lack of access to monitoring application status; and 6) quality checks in upstream process steps (i.e., at the city/provincial and regional local government units) are lacking as manifested by deficient applications forwarded to the national office.

It is recommended that the government takes a proactive approach in assisting the miners in their Minahang Bayan petitions through 1) identification of processing and response times for major steps in accordance with the Citizen’s Charter of concerned government offices; 2) identification of next steps if processing and response commitments are not met; 3) widespread and effective education and information campaign utilizing video presentations, petition template containing the appropriate documents (correct both in form and content) as example; 4) designation of a government personnel to actively coordinate with the miners; 5) provision of an online monitoring facility to enable petitioners to track status of applications; 6) provision of instructional materials aimed at government offices performing different steps in the process to minimize or totally eliminate occurrences of deficiencies; and  7) identification of potential Minahang Bayan areas to be initiated by the Mines and Geosciences Bureau,  with the assistance of local government units, academe and other partners, to lessen external factors affecting the process (e.g. politics).

Indeed, improving the Minahang Bayan declaration process is the crucial first step to realizing and achieving a responsible and sustainable small-scale gold mining. It is the first step that the government really has to take.

DETERMINATION OF INJECTION PARAMETERS USING LINE PRESSURE AND SOLENOID SIGNALS FROM A COMMON-RAIL DIRECT INJECTION DIESEL ENGINE

Ervin S. Santos and Edwin N. Quiros

The determination of fuel injection parameters is very important in studying diesel engines.  Knowing what happens to the fuel as it is being injected onto the engine cylinders may help in understanding the outcome of different engine operations.  Fuel injector behavior affects what happens inside the engine cylinders and may help explain fuel consumption, torque and power produced, emission characteristics, and other engine performance metrics.  Much attention is given to the operation of diesel engines nowadays brought about by the interest in alternative fuel sources.  This study describes a method of estimating actual main injection (excluding pilot injection) parameters: start, end, and duration of injection for a Common-Rail Direct Injection (CRDI) engine based on the information given by the fuel supply line pressure sensor mounted on the tubing that connects the fuel injector to the common rail.   The timing of the fuel supply line pressure signal was compared to that of the associated Electronic Control Unit (ECU) injection command signal to validate a sensible phase relationship. Distinct shape characteristics of the line pressure signal were identified and considered as start and end of actual main fuel injection. The estimation method was used to determine fuel injection behavior of a CRDI engine running at full load from 800 to 4000 rpm.  The study also showed that increasing RPM increases the injection duration, average line pressure and advances the injection timing.

PRODUCTION OF PEPTONE FROM CHICKEN FEATHERS

Bemboy Niño F. Subosa, Jevie S. Mirando, Allan Paolo V. Velasquez, Vera Loise Q. Alamar, Geordan Gerald L. Capinpin, Khrizelle Angelique D. Sablan and Rizalinda L. de Leon

Peptones are the product of a protein hydrolysis, which serve as the main nutrient source for bacteria in a culture media.  This study aimed to provide a locally feasible process for peptone production.  Optimization results for Phase 1 showed that a temperature of 90°C, a digestion time of 4 hours, and a ratio of 0.06 g feathers/mL produced a yield of 50.6%.  Statistical analysis showed that E. coli growth on the laboratory-produced peptone is significantly greater than the growth realized on commercial peptone and plate count agar.  B. cereus growth on laboratory-produced peptone, however, was significantly lower than the growth on commercial peptone and plate count agar.  Purification, drying, and characterization techniques were integrated into the existing process for Phase 2 to obtain peptones with better commercial quality.  The maximum yield obtained was 30 g peptone per 100 g feathers. Freeze-dried powders from the purified hydrolysates had reduced odor and moisture as compared to the vacuum dried peptone. The vacuum-filtered batch also approximated the physical characteristics of the standard peptone hydrolysate.  Performance testing for Phase 2 showed increased support for bacterial growth.

ELECTROCHEMICAL MIGRATION OF SILVER IN ELECTRONICS APPLICATIONS
Manolo G. Mena and Marie Stephanie S. Mena-Junio
Silver (Ag) filler is the most attractive choice among all the conductive fillers. However, silver electrochemically migrates in the presence of moisture and applied bias. In microelectronic devices, silver migration usually occurs between adjacent conductors/electrodes, which leads to the formation of dendrites and eventually results in short-circuit failure. An investigation for two types of fillers was done using the water drop test and a 1000-hour temperature-humidity-bias (THB) test.  Four different bias voltages and six different distance spacings were used for each of the two fillers. The higher voltage requirement for Ag migration to occur for epoxy A than for epoxy C was attributed to the high volume resistivity of epoxy A.  It was discovered that an electric field value of more than 1 volt/mm will start Ag migration.

CONTINUOUS EXTRACTION PROCESS OF CHITIN FROM DISCARDED SHELLS OF PHILIPPINE BLUE SWIMMING CRAB (Portunus pelagicus)

Aileen Grace M. Ongkiko, Lorenz Anthony T. Fernando and Leslie Joy L. Diaz

Crab shells are often found discarded from local seafood processing plants that end up as waste hauled to landfills. However, high purity chitin has been extracted by chemical methods from this material which is useful in various applications like sutures and scaffolding in medical applications. The viable sources of chitin were selected among the shells of blue swimming crab (Portunus pelagicus), mud crab (Scylla serrata) and tiger prawn (Penaeus monodon). Tiger prawn was shown to have the highest yield of chitin at around 24% while the two varieties of crab yielded only about 10%. However, considering the accessibility and availability of high volume of blue swimming crab shells from crab processing plants, this was chosen as the raw material for subsequent investigations. Moreover, the process that will be established can still be suitable for both sources. Extraction process includes demineralization and deproteinization stages and factors affecting them have been studied. These include acid concentration and shell size for the demineralization stage and alkaline concentration and shell size for the deproteinization stage. Retained inorganic component after demineralization and protein content removed from deproteinization were determined using compositional analysis via Energy Dispersive X-ray Fluorescence technique and Lowry assay, respectively, to understand the effects of these factors on their respective processes. It was found that high acid concentration (greater than 1 N) at room temperature could sufficiently remove the inorganic components of the carapace while high alkaline concentration (greater than 1 N) applied to fine-sized demineralized shells produces high purity chitin similar to commercially-available technical grade chitin.

A refinement of the chitin extraction process was subsequently performed through the development of the bench-scale extraction process. It was found out that some of the stages in the laboratory-scale extraction can be eliminated performing an uninterrupted two-stage chemical extraction process and still be able to produce similar quality of chitin with doubled product recovery.

NONLINEAR DYNAMIC DATA RECONCILIATION AND BIAS ESTIMATION OF PROCESS MEASUREMENTS IN AN ADIABATIC STIRRED-TANK REACTOR

Karl Ezra Pilario and Jose Co Munoz

When process data is taken from the sensors of a plant, errors of varying degrees are inherent. Measured variables will most likely violate dynamic process models. Because of this, large volumes of data may be unreliable for process control, monitoring, and optimization. This paper describes a new method for simultaneous Nonlinear Dynamic Data Reconciliation and Gross Error Detection (NDDR-GED) which conditions raw sensor measurements and estimates bias in faulty sensors. The problem is formulated as a dynamic NLP, solved using a hybrid Nelder-Mead Simplex Particle Swarm Optimization (NM-PSO) algorithm and a moving horizon approach. The use of NM-PSO warrants the transfer of solutions, embedded in each elite particle, from one horizon NLP to the next, thereby promoting smoother profiles and faster convergence. This new feature is seen to be a learning mechanism of the method across time. Discretization of ODEs was done using orthogonal collocation on finite elements. Using simulated data from the nonlinear process model of an adiabatic CSTR, the resulting profiles were both smooth (with a percent standard deviation reduction in measurement error of 80-90%) and accurate to the process model within 10-7. Also, large biases were corrected accordingly, if the faulty sensor was known a priori.

UPNEC PERFORMANCE MANAGEMENT SYSTEM USING THE BALANCED SCORECARD
Adeline A. Pacia

The University of the Philippines National Engineering Center (UP-NEC) has been mandated through P.D. 1295 to fortify the country’s continuing efforts at national development. In order to achieve this, the UP-NEC aims to provide technical training to ensure a steady and expanding supply of technical manpower with expertise in the various fields of technology and engineering; as well as, to develop technologies for the sustainable utilization of indigenous resources that address the needs of the local industry. In pursuit of this mandate, UP-NEC applied for and was awarded the Philippine Quality Challenge (PQC) Level 1 in 2012 and the Philippine Quality Award (PQA) Level 1 in 2016. PQA is not only a national recognition for exemplary performance, it also stimulates local companies and organizations to improve quality and productivity in fulfilling its mandate and its vision to be the HUB of Engineering Innovations and Technology.

The findings and recommendations from the PQA Team of Assessors identified UP-NEC’s strengths as well as opportunities for improvement. With the assessment, it was deemed that a more strategic performance assessment is needed to ensure that UP-NEC is able to fulfill its mandate and its vision. The Balance Scorecard was chosen as the performance measurement and strategy management system to align its strategic objectives of Service, Reach and Self-sufficiency with the attainment of goals for the employees and partners, effective internal processes, service to its clients and stakeholders as well as financial sustainability.

The study discusses the National Engineering Center’s (UP-NEC) proposed Balanced Scorecard strategies and initiatives to attain its strategic objectives and move towards being a true hub of engineering innovations and technology in support of the country’s continuing efforts at national development.
