GUIDELINES FOR THE UPERDFI PROFESSORIAL CHAIR AWARDS
College of Engineering, University of the Philippines Diliman

The UPERDFI Professorial Chair Award (PCA) is a form of recognition for achievements in the academe. The award aims
to encourage the faculty to advance knowledge and learning in the various fields of engineering. Any regular full-time
faculty member with rank of Assistant Professor or higher and with outstanding credentials in academic, teaching,
research, service to the university/community, and professional growth may be considered for the award.
Eligibility

1. An applicant for PCA must be a full-time faculty member of the UP College of Engineering with the rank of
Assistant Professor or higher, and should have continuously served the college as a regular faculty member for at
least one (1) year and the UP System for a cumulative period of 5 years.

2. An applicant for PCA must have a minimum of twenty four (24) units total load credit per academic year including
mid-year term with at least three (3) units of teaching load course credit per semester. Faculty members who are
on secondment /special detail or on leave (except sabbatical leave) are not eligible.

3. There is no limit to the number of times a faculty member may receive the PCA, the sole basis of the award being
merit, provided that only one professorial chair award is given at a time to any faculty member.

Selection
1. The Dean shall announce the call for PCA applications and the number of slots available for the award in June.
2. Deadline for submission of applications for PCA will be on the 1st Monday of August. Documents for
consideration of the award: (1) an original research paper (single author or multiple authors is acceptable,
published or unpublished in a refereed journal wherein one published paper is required over a three-year period)
and (2) the PCA worksheet indicating faculty loading for the academic year prior to the selection and other
pertinent information such as the proposed title of the research to be done during the coming academic year,
must be submitted to the Department Chair or Institute Director at the time of application. For renewal of
appointment, the PC holder need only to submit a copy of his/her original research paper in addition to the
required PCA Renewal worksheet. New PCA applicants (those not awarded the previous academic year) and
those applying for upgrade to a chair in higher category are required to submit the PCA worksheet for New PCA
applicant and the accomplished Worksheet of Accomplishments for the past three academic years detailing the
points earned in Teaching, Research/Creative Work, Service and Professional Growth categories.
PCA awardees are required to disclose and show proof if the PCA paper has been submitted for publication in a
reputable local/international journal or for presentation in a conference or other fora. The PCA publication
obligation shall be considered fulfilled provided that the publication or oral presentation falls within the period of
evaluation.
Proof of Publication or Presentation are as follows:
a. For journal publication
i. Written letter of acknowledgement of submission, OR
ii. Written letter of acceptance or Photocopy of actual publication
b. Conference/Forum Presentation
i. Proof of the oral presentation (e.g., program, pictures, etc.), OR
ii. Conference/Forum Proceedings
For the benefit of the donor, recipients of the PCA are enjoined to make an oral presentation during the
Department/Institute PCA Colloquium usually held during the month of October. They are also requested to
personally invite the donor or representative to the colloquium and write the donor a letter of thanks .
Depending on the available funding for a chair, applicants for renewal may be transferred to an available vacant
chair of the same category. Such cases will not require the faculty to compete with other applicants.
Those occupying chairs with awards higher than 120 K (except the 300 K chair reserved for the Dean) can be
renewed without competing with other applicants for a period of three years from the time the award was given.
After the end of the 3-year period, they will be considered to be New PCA applicants and have to compete with
applicants for the same chair previously given to them and will be ranked based the criteria detailed in item 3.
Recipients of chairs with awards higher than 120 K must sign a PCA Conforme agreeing to the conditions of their
award in order that they can apply for renewal each year without need to compete with other applicants over the
three-year period, otherwise they will again be considered as New PCA applicants in the next round of selection.

3. Applications shall be evaluated first by the Department Chairs/Institute Directors and the respective Department/
Institute Academic Personnel Committee (DAPC/IAPC), and thereafter by the Dean and the College Academic
Personnel Committee (CAPC).
Evaluation of new applications and applications for PCA upgrade shall be based on the following criteria and
weights which depend on the rank for Teaching and Research/Creative Work.
•Teaching: 45% for Asst. Professor, 40% for Associate Professor and 35% for Full Professor
•Research/Creative Work: 35% for Asst. Professor, 35% for Associate Professor and 40% for Full
Professor
•Service to University/Community: 10% for Assistant Professor, 15% for Associate Professor and Full
Professor
•Professional Growth: 10% (all ranks)
A divisor will also be applied to the average of the raw points for the three year period in computing the ranking
based on faculty position as follows:
Divisor = 60 if Assistant Professor
Divisor = 80 if Associate Professor
Divisor = 100 if Full Professor
The rank score considering the divisor and the weights will have a maximum possible value of 100. The highest in
any of the four categories (Teaching, Research/Creative Work, Service, Professional Growth) will get the
maximum score in that category equal to the weight% assigned for that category according to his/her faculty
position.
For new PCA applicants, in order to qualify for a certain category of the PCA Award, the following raw points
(average of last 3 years) must also be met:
60 points for 80 K Chair
90 points for 120 K Chair
1120 points for 150 K Chair (under UP Foundation)
2180 points for 240 K Chair
3225 points for 300 k Chair (new Chair for ICE faculty)
Renewal applications of those who have held 120K, 150K or 240K valued chairs for three consecutive years shall
be evaluated using the applicant’s accomplishments over the past three years. Those applying for upgrade will
also be evaluated based on their average raw points for the past three years.
Awarding of chairs will also be based on the wishes or requirements of the donor. Some chairs specify a certain
expertise or may be reserved only for applicants from a certain Department/Institute. There are certain generic
chairs open to faculty members from any Department or Institute.

5. The final list of awardees shall be determined by the Dean and CAPC based on the competitive scores of all
applicants for the whole COE.

6. The Dean shall submit the recommendations for the award to the Chancellor/HRDO within September, in time for
conferring the award in October/November.

INPUT POWER RANGE EXTENSION USING DUTY-CYCLING AND GRANULARITY REDUCTION
IN A 5.8GHz RF ENERGY HARVESTER DYNAMIC MATCHING CIRCUIT

Using a continuous dynamic matching circuit in an RF energy harvester ensures the desired output voltage is
achieved over the input power range. However, the minimum harvestable power level is limited by the power
overhead of the continuous dynamic matching circuit. In order to reduce this power overhead, the processing
and actuating block of the control system are duty-cycled. In addition, reducing the granularity or the number
of the matching circuit sets lessens the power overhead needed for sensing, processing, and actuating. The
RF energy harvester was implemented using an intermittent dynamic matching circuit to improve its input
power sensitivity. By reducing the power overhead of the dynamic matching circuit, the RF energy harvester’s
lower input power limit was extended from -7dBm to -20dBm.

BIT-SELECTION CONTROL FOR ENERGY-EFFICIENT HAND-WRITTEN DIGITS RECOGNITION
HYPERDIMENSIONAL COMPUTING ARCHITECTURE

Hyperdimensional computing (HDC) is a braininspired computing framework that provides simple and
convenient methods to perform cognitive tasks like classification. Its foundation lies in the properties of very
high dimensional vectors called hypervectors (HV). Despite being a promising alternative to the conventional
von-Neumann architectures, generic HDC architectures contain massive bit-wise operations. Current
optimizations often have to sacrifice accuracy for better energy. This work identified that there exists
redundant bits in the associative memory. These redundant bits do not contribute any information during
classification. With this, a low-complexity bit-selection control is developed to only use the relevant bits to
achieve better energy without sacrificing accuracy. For a handwritten digits recognition problem, this
mechanic resulted in a 44:62% energy reduction at the cost of 8:34% increase in area.

HIGH CONTRAST GRATINGS (HCG) MEMS-TUNABLE VCSEL COMPACT MODEL
High contrast grating (HCG) microelectromechanical structure(MEMS)-tunable VCSELs have advantages that
make them promising for applications like optical coherence tomography (OCT), light detection and ranging
(LIDAR), and dense wavelength division multiplexing (DWDM). Circuit simulator-compatible laser compact
models can aid circuit designers in improving the performance of systems that use them. While a compact
model for VCSEL already exists, it does not sufficiently describe the behavior of tunable VCSELs. This paper
discusses the creation of a compact model for HCG MEMStunable VCSELs implemented in Verilog-A using
semiconductor laser rate equations. The simulated output power, laser diode voltage, and emitted wavelength
at varying applied MEMS tuning voltage of the compact model agrees with the measured values with mean
percentage errors of 7.0%, 5.3%, and 0.32% respectively.56

MATA: MISSION, ATTITUDE, AND TELEMETRY ANALYSIS SOFTWARE
FOR MICRO-SATELLITES

With the rise in popularity of small satellites, there has been an increasing demand for a software tool that
covers different stages of satellite development. In this paper, we extend a small satellite simulation software
originally developed for earth-observation satellites Diwata-1 and Diwata-2 to support other satellite missions.
This support covers various stages: from ideation, development, and up to post-launch assessment. This
paper focuses on the Mission, Attitude, and Telemetry Analysis (MATA) software, which can simulate orbit,
attitude, and camera views from planned earth-observation missions.
Satellite engineers can also use MATA in a hardware-in-the-loop configuration, serving as one of the last
functionality checks before launching the satellite. MATA can also read telemetry files from an orbiting satellite
and re-project it in a virtual environment for a more intuitive assessment. This paper also covers the
implemented framework for the simulator. This framework would help future developers to extend the
simulator to other applications like star tracking simulations, mixed reality satellite training, and space
educational software.

A GREEDY DEGRADATION OF DISCRETE MEMORYLESS CHANNELS WITH LARGE OUTPUT
ALPHABETS

The channel capacity of discrete memoryless channels is hard to compute, especially for channels with large
output alphabet sizes. In the design of polar codes, the channel capacity can be used to identify the most
reliable and least reliable channels that will aid in the selection of frozen bits. Synthetic channels produced by
channel polarization tend to have exponentially large output alphabets due to both the blocklength and the
successive cancellation decoder. In this paper, we present an algorithm to reduce the output alphabet size of
such channels by grouping output symbols that roughly contain the same information about the transmitted
bits to any receiver. We first calculate the bounds on information loss, and then present a theorem that
justifies a closeness-constrained grouping procedure. Finally, we present a numerical example demonstrating
the amount of reduction achieved by our proposed algorithm using the binary symmetric channel.

RUBBLE-PENETRATING S-BAND LIFE DETECTOR USING A SOFTWARE-DEFINED RADIO
Earthquakes and landslides are common in the Philippines due to the country’s geography being situated
along the Pacific Ring of Fire. In such events, structural collapse could occur and potentially trap humans
inside. Rescue efforts either blindly search for the survivors or use expensive equipment to aid their search.
Such equipment cannot be distributed to every local government unit. In this paper, we propose a low-cost
light-weight vital sign detection system using radar technology. We have shown that a software-defined radio
operating at the S-band can be used to detect human vital signs over a concrete wall. Due to its light weight, it
can be mounted on a drone to improve the time it takes to rescue survivors.

VISION TRANSFORMER FOR FAST AND EFFICIENT SCENE TEXT RECOGNITION
Scene Text Recognition (STR) systems have various practical applications in areas where visual clues in the
form of printed text in the human environment can provide automated answers to questions. Unlike optical
character recognition (OCR), STR has to deal with numerous challenging conditions such as variations in font,
style, orientation, size and geometry, presence of noise, blur and distortion and effects of weather condition to
name a few. The problem with state-of-the-art (SOTA) STR models is that they are a composition of various
models and algorithms assembled together to successfully recognize text. Therefore, these models are
inherently slow and inefficient. In our proposed Vision Transformer for STR (ViTSTR), we demonstrated that
we can build a single stage model with good accuracy vs number of parameters, FLOPS and inference time
trade-offs. To overcome the problem due to different text appearances, we also developed a Data
Augmentation for STR Python library, called STRAug, that can be used to reduce the generalization error.

SVM-BASED DETECTION OF FALSE DATA INJECTION IN INTELLIGENT TRANSPORTATION
SYSTEM

Vehicular Ad-Hoc Network (VANET) is a subcategory of Intelligent Transportation Systems (ITS) that allows
vehicles to communicate with other vehicles and static roadside infrastructure. However, the integration of
cyber and physical systems introduce many possible points of attack that make VANET vulnerable to cyber
attacks. In this paper, we implemented a machine learning-based intrusion detection system that identifies
False Data Injection (FDI) attacks on a vehicular network. A co-simulation framework between MATLAB and
NS-3 is used to simulate the system. The intrusion detection system is installed in every vehicle and
processes the information obtained from the packets sent by other vehicles. The packet is classified into
either trusted or malicious using Support Vector Machines (SVM). The comparison of the performance of the
system is evaluated in different scenarios using the following metrics: classification rate, attack detection rate,
false positive rate, and detection speed. Simulation results show that the SVM-based IDS is able to provide
high accuracy detection, low false positive rate, consequently improving the traffic congestion in the simulated
highway.

TEXT-TO-SPEECH SYSTEMS FOR TAGALOG USING UNIT SELECTION AND DEEP LEARNING
There are several text-to-speech (TTS) systems developed and published for Philippine languages,
particularly in Tagalog and Cebuano. However, there is still a need to improve the performance of existing
systems. Due to the limited amount of linguistic resources and lack of speech data available for Philippine
languages, developing a reliable TTS system to support these languages becomes difficult.
In this paper, we implement and evaluate the performance of two TTS systems for Tagalog. We implemented
two methods: unit selection using MaryTTS and deep learning approach using Tacotron-2. We also compared
the performance of the systems when enhanced. For the unit selection-based system, prosody modification
was applied to the synthesized speech. For Tacotron-2 system, data augmentation was implemented using
voice conversion (VC) to provide more training data. The prosody-modified unit selection system yielded an
overall MOS of 2.74 which is lower than baseline unit selection system having a MOS of 3.05. The Tacotron-2
system significantly improved from an overall MOS of 1.51 to 2.01 using data augmentation.

NEURAL NETWORK MODELS FOR PATH PREDIC5ON PROBLEMS
This paper addresses the problem of the path prediction for multiple pedestrian agents in a given scene by
personalizing each prediction based on each individual characteristics of an agent. It has already been proven
that more features mean a more accurate path prediction. The problem is in how these features are handled
as to not compromise the computation time. We hypothesize that if a learned path prediction network bases
its predictions on how a specific agent moves and not on the movement of all other persons in the training
dataset, it will in turn generate a future path that is close to how the person actually moves and hence more
accurate for any person. This will in turn also make the network more generalizable to other scenes. Most
works that do this either require a manual labelling of obstacles, and an incomplete comparison to other state-
of-the-art methods. We propose Person-GAN, a network that “personalizes” path predictions for each agent
regardless of the environment given to the network by making use of a set of personalization features specific
to each agent. Some of these personalization features have already been used in recent works (Bartoli, et al.,
2018; Kitani, et al., 2012; Ma, et al., 2017; Kooij, et al., 2014; Sadeghian, et al., 2019) but for Person-GAN, we
augment the agent feature set and experiment on the optimal local environmental feature map that produces
the best prediction. We also minimize the dependency of the network performance to other feature extraction
networks by directly getting the agent features from the actual trajectory data.

STRESS DETECTION USING SMARTPHONE EXTRACTED PHOTOPLETHYSMOGRAPHY
Stress is present in our daily lives and can affect anyone. It can be induced by many factors and can lead to
many health complications such as depression, anxiety and even heart disease. Multiple research found that
stress is highly correlated with physiological signals especially pulse rate variability (PRV). In this paper, we
generated multiple machine learning models which uses PRV features extracted via photoplethysmography
(PPG). Since multiple studies proved PPG can be performed by smartphones, we further compared the stress
detection performance for wearables and smartphone extracted data. Moreover, principal component analysis
(PCA) and three different time length were observed to check how it will affect the performance of different
models. Results from 30 participant shows that Random Forest algorithm achieved the highest classification
accuracy for both smartphone and wearable device. An accuracy of 77.65% and 74.51% was achieved for the
wearable and smartphone respectively.

ADEQUACY ASSESSMENT OF THE PHILIPPINE LUZON GRID FOR DIVERSE POWER
EXCHANGES

Recent circulars from the Philippine Department of Energy mandate the country’s transmission network
provider and system operator to consider increased penetration of varia-ble renewable energy, energy
storage systems, and flexible load under a market environment in making its Transmission Devel-opment Plan
(TDP). These trends will increase the diversity of power exchanges in the grid that need to be accounted for in
transmission planning. With this background, the contribution of this work is two-fold. First, we review the new
sections in the Consultation Draft of the TDP for 2021-2040 published in Jan-uary 2021 as a response to the
DOE circulars. And second, we present how recent work in planning under more diverse power exchanges
can be adapted in future TDP activities. We illustrate using a reduced approximate model of the Luzon grid
where we identify potential grid bottlenecks that give insights to the grid’s adequacy to handle more diverse
power exchanges.

EVALUATING THE PACKET FILTERING PERFORMANCE OF XDP eBPF
With the increasing amount of traffic being sent at faster speeds, traditional packet processing introduces
overhead, which bottlenecks overall network performance. Kernel bypass methods are used to address this
issue but these are difficult to integrate into existing network applications. A more recent approach being
investigated in this project is through offloading to the kernel or a dedicated hardware, implemented using
eBPF (extended Berkeley Packet Filter) XDP (eXpress DataPath). Few studies have evaluated the
performance of XDP and there is a need for a deeper assessment of its benefits in real-world use cases. This
work investigated the performance benefits and drawbacks of XDP offloading. Experiment results showed that
hardware offloading performs best in terms of throughput, latency, and CPU usage as compared to kernel
offloading and iptables. Kernel offloading showed no significant performance gain over firewall filtering.
Hardware offloading significantly reduced the impact of packet processing on the system to a negligible
percentage, decreasing latency to an average of 0.16 ms by eliminating kernel overhead and increasing
throughput to up to 4.5 Mpps, more than double the throughput of kernel offloading and iptables. Our findings
demonstrate that hardware offloading offers significant overall performance gain for packet filtering.

help in resource conservation efforts by the use of a Wireless Sensor and Actuator Network (WSAN). Agrinex
system features a mesh-like configuration of in-field nodes that act both as the sensor for soil moisture,
temperature and humidity and actuator on a valve that regulates drip irrigation. The mesh-based network is
dynamically design to allow self-reorganization of sensor nodes when changes happen in the network. The
resulting Agrinex system is a promising start for a WSAN framework of various applications particularly in
agriculture.

FAIL-SAFE CONTROLLER ARCHITECTURES FOR QUADCOPTER WITH MOTOR FAILURES
A fail-safe algorithm in case of motor failure was developed, simulated, and tested. For practical fail-safe flight,
the quadcopter may fly with only three or two opposing propellers. Altitude for two-propeller architecture was
maintained by a PID controller that is independent from the inner and outer controllers. A PID controller on
propeller force deviations from equilibrium was augmented to the inner controller of the three-propeller
architecture. Both architectures used LQR for the inner attitude controller and a damped second order outer
controller that zeroes the error along the horizontal coordinates. The restrictiveness, stability, robustness, and
symmetry of these architectures were investigated with respect to their output limits, initial conditions, and
controller frequencies. Although the three-propeller architecture allows for distribution of propeller forces, the
two-propeller architecture is more efficient, robust, and stable. The two-propeller architecture is also robust to
model uncertainties. It was shown that higher yaw rate leads to greater stability when operating in fail-safe
mode.

SEGMENTED SOFT PNEUMATIC BENDING ACTUATOR WITH ARTIFICIAL NEURAL NETWORK
FOR PARAMETER PREDICTION

Most of the models of soft robotic gloves can do flexion and extension. However, there are other hand
rehabilitation exercises such as tendon glide which requires variations of finger pose. It cannot be done with
just a single motion of flexion or extension. Individual joint control is needed in order to achieve the normal-to-
maximum range of motion when doing the hand exercises. In this paper, a design of a segmented soft
pneumatic bending actuator (sPBA) with individual joint control using PID with Artificial Neural Network (ANN)
for parameter prediction is presented. Each joint has its individual inlets and has pneumatic chambers that
bends when supplied with air. A pneumatic control setup is developed to control the three finger joints; the
Metacarpophalangeal (MCP), Proximal Interphalangeal (PIP), and the Distal Interphalangeal (DIP). Varying the
air pressure supplied to the joints achieves different bending positions of the finger. An experimental setup
was developed in order to characterize and gather data that is used to develop ANN for predicting the
bending angle-to-pressure parameter. A total of 2197 images are captured from the different combinations of
pressure which are equivalent to different bending angles. A simple PID control was used to achieve the
desired bending. The setup has a mean-square-error (MSE) of 1.85007 at validation with overall R of 0.9994
and a maximum error of 5.4 kPa pressure in joint 1 at low pressure. This setup will be useful to develop a soft
robotic rehabilitation glove.

A CONSTANT TEMPERATURE FAST CHARGER FOR LITHIUM BATTERIES
The use of lithium-ion batteries has been widely accepted in many different applications due to their relatively
higher power and energy densities compared to other storage technologies. In utilising lithium batteries for
electric vehicles, one of the recent challenges was how to fast charge this battery in a safe and efficient
manner. Most consumers and end users of lithium batteries utilize the constant oltage, constant current
chargers because of their availability. These chargers have been widely used in lead acid technologies and
have become cheaper and readily available. In trying to decrease the charging time for lithium batteries, the
typical way of approaching this problem is just to increase the charging current. This method, however, has a
bad impact on the life of these types of batteries because of the significant increase in charging temperature.
A significant increase in charging current would let the batteries operate beyond the recommended operating
temperature. This paper investigated the impact of charging lithium batteries while maintaining the
temperature. This resulted in a configuration that starts with a constant temperature control up to 80% SOC
and finishes the charging with a more traditional CC-CV algorithm.
In implementing a control scheme that starts with a constant temperature control, the battery may be charged
with a high current until the temperature setpoint has been reached. This lets the battery accept a high rate of
charge without exceeding the recommended operating temperature level. The safety and health of the battery
is not compromised. The battery does not degrade easily, and thermal runaway is avoided.
Batteries were modelled to determine their thermal characteristics in determining the optimum level of the
initial charging current. The simulations compared the performance of the CC-CV charger with the proposed
CC-CV charger with a constant temperature mode. Results show that an optimum charging current level may
be obtained with the constant temperature mode to achieve fast charging without exceeding the
recommended operating temperature levels.

SECURITY AND RELIABILITY CONSTRAINED UNIT COMMITMENT IN POWER SYSTEMS WITH
INTERRUPTIBLE LOADS

An efficient power system must be able to supply electricity to its load in a secure, reliable and economical
manner during any period of operation. As power systems are being driven closer to their security
limits while being subjected to uncertainties in generator and network availability and in load forecasts,
there is a need to simultaneously incorporate security and reliability constraints to the unit commitment
problem. Interruptible loads provide a cheaper addition to generator spinning reserve in order to satisfy
probabilistic criteria for required operating reserve. This study proposes a mixed-integer nonlinearly
constrained formulation of the unit commitment problem that simultaneously satisfies both security and
reliability constraints. The reliability constraints are incorporated using the loss of load probability index in
order to determine the required reserve over a 24-hour period. The effectiveness of the proposed
methodology is evaluated using a standard six-bus, three-generator test system.

FAULT LOCATION BASED ON LOAD COMPENSATION
Accurate and fast location of faults is essential in distribution system operation to ensure continuity and quality
of power supply. Earlier impedance-based fault location techniques such as Equivalent Impedance Based
(EIB) and Load Level Based (LLB) perform load variation compensation but assume a uniform percent load
change across all connected loads; such assumption is hardly applicable in distribution systems where
various types of loads are connected. It was observed in this study that their accuracy reduces as the fault
current becomes comparable to the load current. This research performs load variation compensation by
considering the load profiles of the various types of loads connected in the distribution system -- an
information that has become more available with Philippine distribution utilities. By doing this, loads are better
represented in the simulation, which results in better prediction accuracy. The proposed method, Load Profile
Based (LPB) produced better results compared to the earlier methods in simulations conducted in an actual
distribution feeder from Cagayan II Electric Cooperative. In these techniques, a phasor measurement unit
(PMU) is assumed to provide reference phasor voltage and currents at the root node. We further illustrate that
additional PMU improves fault location by improving load variation compensation and faster fault location as
PMU provides boundaries and effectively reduces the search space.

Compensation, Philippine Engineering Journal (PEJ), vol. 42 no. 1, National Engineering Center, 2021.} is a collaboration between

SIMULATION PLATFORM FOR OPTIMAL PRICING OF A DISTRIBUTION UTILITY WITH
DISTRIBUTED ENERGY RESOURCES OPERATING IN A RESIDENTIAL COMMUNITY

The current power grid system in the Philippines allows the consumers to utilize any amount of electrical
energy as long as they can pay for it. As a response, the utilities need to meet the demand at all times by
purchasing energy from the generating plants whatever the cost may be. Today, these distribution utilities
started to explore the usage of distributed energy resources in order to cater these varying demands,
especially the peak demand. Moreover, the number of consumers which implemented transactive energy
schemes also continues to increase. If this interaction between the utility and the consumers will be well-
coordinated, reduction in the electricity price and energy consumption would be possible. This paper
describes a computing tool and was able to (1) solve for the electricity tariff, (2) produce schedule of energy
dispatch from distributed generators and storage systems and (3) perform proper demand-side management
through scheduling of appliance operations, in order to reduce the cost of customer energy consumption at
the same time maximize the allowable utility profit.

A RESPONSE SURFACE METHOD APPROACH TO MODULAR STATOR, SEGMENTED ROTOR
SWITCHED RELUCTANCE MOTOR DESIGN

The switched reluctance motor (SRM) lends itself well to structural modification to improve its torque
performance and to enhance its fault tolerance. These alterations include rotor and stator segmentation, with
the latter showing promise in increasing the fault tolerance through motor modularization. A statistical, design
of experiments approach is used in this study to design a segmented stator, segmented rotor 12-8 SRM
(SSSR-SRM) approximately the size of a NEMA 56 frame. The modularity of this SRM is improved by having
the coils along the rim instead of the usual pole tooth and having these independently wound of each other.
By using response surface methodology (RSM), the optimal sizing that produces the maximum average
output torque for the SSSR-SRM of the given size and dimensional constraints is found. The response surface
generated can also be used to predict the output torque of SSSR-SRM with different physical dimensions.

AN ANALYSIS OF THE EFFECT OF A BATTERY ON THE LOAD SCHEDULING OF
PHOTOVOLTAIC GENERATED HOUSEHOLD LOADS CONSIDERING ELECTRICITY PRICE

VARIATION
Load scheduling is a demand side management method that directs end-users to modify their energy
consumption in accordance with a schedule provided by the utility. The customer benefit usually manifests
from a time of use (TOU) pricing scheme wherein loads are shifted away from the high electricity cost of peak
demand conditions. Aside from this, many modern households employ the use of solar photovoltaic systems
with energy storage to reduce the over cost of electricity consumption. Combining energy storage to load
scheduling is an interesting problem that can yield positive results in further reducing the cost to the
consumers. In this paper, a load scheduling algorithm that incorporates the battery charging and discharging
cycles for a photovoltaic powered home is developed. Case studies were conducted to validate and test the
effects of the solar battery to the household load schedule. The results indicate the energy storage added an
additional flexibility to the scheduling and can have a significant effect on the reduction of household
electricity cost if sized appropriately.

UNRAVELLING SPATIAL PRIVACY RISKS OF MOBILE MIXED REALITY DATA
Previously, 3D data—particularly, spatial data—have primarily been utilized in the field of geo-spatial analyses,
or robot navigation (e.g. self-automated cars) as 3D representations of geographical or terrain data (usually
extracted from lidar). Now, with the increasing user adoption of augmented, mixed, and virtual reality (AR/MR/
VR; we collectively refer to as MR) technology on user mobile devices, spatial data has become more
ubiquitous. However, this ubiquity also opens up a new threat vector for adversaries: aside from the traditional
forms of mobile media such as images and video, spatial data poses additional and, potentially, latent risks to
users of AR/MR/VR. Thus, in this work, we analyse MR spatial data using various spatial complexity metrics—
including a cosine similarity-based, and a Euclidean distance-based metric—as heuristic or empirical
measures that can signify the inference risk a captured space has. To demonstrate the risk, we utilise 3D
shape recognition and classification algorithms for spatial inference attacks over various 3D spatial data
captured using mobile MR platforms: i.e. Microsoft HoloLens, and Android with Google ARCore. Our
experimental evaluation and investigation shows that the cosine similarity-based metric is a good spatial
complexity measure of captured 3D spatial maps and can be utilised as an indicator of spatial inference risk.

UTILIZATION OF PLASTIC LAMINATES IN ASPHALT CEMENT MASTIC

In the Philippines, plastic laminates are seen everywhere because most of the products consumed are sold in
sachet packets. These packets are composed of multiple layers of polymers, making them very difficult to
recycle. Numerous studies concerning plastic waste as an additive to concrete and asphalt have shown
increase in strength, decrease in deflection, and decrease in the overall construction cost. In this research,
shredded plastic laminates were used as a partial substitute to bitumen (pen. 60/70). Volume replacement of
plastic laminates to bitumen was performed from 0% to 100% with increments of 10%. The samples were
tested for softening, penetration, and ductility. Results of the tests showed that as the replacement percentage
increased, the penetration and ductility of the mastic decreased, while the softening point increased. This
indicates that the mastic becomes tougher and brittle with the addition of plastic laminates. Both the
penetration and softening point for the samples passed the standards provided by DPWH, which indicate that
should the modified asphalt mastics be used in asphalt concrete, it would be less likely to deform under
repeated loading, it would also be less susceptible to temperature changes. Meanwhile, the ductility measured
for the modified asphalt mixtures did not pass the standards provided by D.O. 152. This may indicate an
increase in the asphalt pavement’s tendency to crack under repeated loading. Despite the significant
improvement in the physical properties of the binder even at 10% replacement with the plastic laminates, the
presence of foil may have contributed to the loss in ductility. Further studies should be conducted considering
a smaller replacement range between 2-10%.

DEVELOPMENT OF AN APPLICATION FOR THE VULNERABILITY ASSESSMENT OF PHILIPPINE
BUILDINGS AGAINST SEVERE WINDS

In 2020 alone, three significant typhoons named Quinta, Rolly, and Ulysses consecutively caused catastrophic
damages to the country in three weeks. Currently, government organizations partner with local government
units through different research projects to produce area-based risk assessment maps for other localities in
the Philippines. These projects for risk assessment often entail highly technical methodologies that often
require a steep learning curve. Aside from this, computer simulations need multiple software and have long
computational periods that may last for days. These complications discourage stakeholders from conducting
detailed risk assessments of low-rise structures against severe wind loadings. This paper presents the
development of a feature-based application that uses a simple and intuitive graphical user interface to aid
stakeholders in conducting risk assessments of individual low-rise buildings. The evaluation of the buildings is
done by determining the performance of the building envelope components such as the roof fasteners, roof
purlins, roof-to-column connections, and exterior windows against severe wind loads. A linear analysis using
line elements will be used for the main wind force resisting system for the structural analysis. A Monte Carlo
simulation engine is employed that requires wind pressure coefficients and probabilistic building envelope
capacities, determined experimentally or from related studies, to generate vulnerability and fragility curves.
The integrated development environment (IDE) used was the MATLAB® App Designer, wherein the structural
analysis was performed through SAP2000®.

OPTIMAL DESIGN OF ONE-WAY REINFORCED CONCRETE HOLLOW BLOCK WALLS
SUBJECTED TO NON-UNIFORM BLAST LOADS

Unlike against typhoons and earthquakes, the National Structural Code of the Philippines (NSCP) and other
design provisions in the country do not have guidelines for the analysis and design of buildings against blast
loads. Recent blast events in the country, however, proved that buildings are vulnerable to blast loadings and
there is a need for a detailed analysis and design procedures. In this presentation, recent developments on
the analysis and design of concrete hollow block walls subjected to blast loading at the UP Institute of Civil
Engineering are presented. Blast phenomenon is reviewed and its idealization or implementation in codes,
such as in ASCE/SEI 59-11 and the Unified Facilities Criteria, is also presented. Along with the analysis
procedures making use of an equivalent single degree of freedom (SDOF) for one-way walls and Discrete
Element Models, tools or programs developed by researchers were presented. These simple tools were
developed to automate pressure computation and generation of models of walls and buildings taking into
account types and properties of different materials used, and the changes in properties when subjected to
large strains. It was shown that the numerical models were able to reasonably replicate experimental results
from literature. For one-way walls, a procedure for optimal design making use a SDOF wall model subjected
to blast loading was also presented. The proposed procedure considers the non-uniform pressure distribution
for near-field surface blast loads. A procedure making use of proposed charts was shown to simplify the
otherwise laborious design process. In conclusion, the presentation highlighted the following key
contributions: (i.) methods for the analysis and design of structures subjected to blast loading, (ii.) tools useful
in analysis and design, and (iii.) charts for design and performance evaluation of reinforced masonry walls.
