Abstract
Proposed Tactical Troops Tracking
System
It is seen that a single U-LoRa gateway is exploited inthe center of an investigation area. The U-LoRA End-Nodescan be as much as preferred, but there are six nodesdemonstrating in this system. All the end-nodes are
connected to the LoRa gateway before transmittingto the Layer2 network switch under IoT and web server.All the data will be transferred to the networkbefore visualizing on the graphic user interface.
The system can be extended to a wider range
area within 5×5 kilometers. The systems can beexpanded to the tactical troop tracking system witha four gateway with four point-to-point Wi-Fi bridges.
Such a system could provide wider coverage.
It should be noted that the gateway should be in
an appropriate height in order to be capable of
receiving signals from each end-nodes, and theelectrical surge system should be considered and
integrated in order to protect from any possible
failures.
Implementations and
Experimental Results
Performance analysis has been tested at Thai-NichiInstitute of Technology where the gateway was installed
at the 6th floor of C-building with a height of 500 meters.The coverage range has been incremented by 100 meters
with actual obstacles as depicted. The performances were
investigated by received signal strength indicator (RSSI),which is a measurement of the power present in a received
radio signal. It should be noted that RSSI is usually expressedin dBm from 0 to approximately lowest at -120 dBm.In addition, Signal-to-Noise Ratio (SNR) has also beeninvestigated and is defined as the ratio of signal powerto the noise power expressed.

Conclusion
A Future Work on The Procosed Smart
PPEs Platform
Based on the reviews, it is noticeable that hazardous gassensors or other particle matter measurements (PM2.5-10)have not been studied. In addition, Graphic User Interface(GUI) as well as data is not recoded in cloud storage. Therefore,the conceptual framework for complete smart PPE isintroduced for the future work. Fig. 10 depicts the roughconcept of a future work for smart PPE Platform. As illustratedin Fig.10, the life vest comprises a heart rate monitor sensor,a Gyroscope, an accelerator sensor, a motion sensor andhazardous gas sensors. The four sensors are connected to
a wireless transmitter which is expected to LoRa node tosend data through a cloud system in order to display on
the web application with warning system and simple GUI

Abstract
The PPE is a potential barrier as the final option toalleviate the effects of possible accidence. Despiteaccident causation and prevention techniques,motivating and controlling workers to wear PPEsrequires its own efforts. Employers may address the
use of PPEs in three ways, i.e. (i) education and training,(ii) incentives, and (iii) enforcement. Some operatorsdo not prefer to wear PPEs because they either forgetor find it uncomfortable to wear PPEs. Other factorsinvolve (i) PPEs may have an impact productivity,(ii) exposure to a hazard is short and thus PPEsare not needed, and (iii) inadequate or not availableeducation and training for using PPEs. In order tosolve these issues, employers can improve theconsistency of PPE use by applying best practicesassisted through novel technologies. These could
subsequently meet the employer's.
Smart PPS by KAN-Commission for OccupationalHealth and Safety and Standardization Company
has created smart PPS. Communication and localization devices are available in the wearer, consisting of varioussensors for body functions and environmental monitoring, e.g. for fire-fighters. It has cooling and heating functionsthat operate only when necessary based on measured body and external temperatures. Active PPE acting asan emergency stop, for example for laser devices or chain saws when they endanger the safety of the wearer ofthe PPE and installed light-emitting flexible materials that provide high visibility.
The IoT-Based industrial PPEs from both in academic and commercial point of view. The review results have revealedthat most smart PPEs have sensors for real-time monitoring of operator health conditions, but realization andimplementation are still in early stage. Most wearable sensors found from the reviews are gyroscope, accelerator,GPS, and those sensors for measuring body temperature and heart rate measurement. Some particular sensorsare exploited for measuring Electrocardiogram, Photoplethysmogram, and Galvanic Skin Response Blood pressure.Communication modules are mostly RFID, Zigbee, and ad-hoc network in IEEE 802.15.4. Based on the reviews,it was found that hazardous gas sensors or other particle matter measurements (PM2.5-10) have not been studied.In addition, Graphic User Interface as well as data is not recoded in cloud storage.
Research BackgroundsResearch BackgroundsAn appraisement of Human Happiness Level (HHL) based on Air Quality (AQ) through the use of Fuzzy LogicInference System (FIS) system. Such a FIS has recently been realized as a potential alternative to that of
conventional AQ assessment based on standard scales, which encounter practical difficulties on complicatedmeasures of various hazardous attributes and levels of chemical compounds in air. Despite the fact that severalfuzzy-based AQ models have been reported, no fully-developed AQ model that considers from physical attributesto human actualization, especially happiness, has been reported. In this paper, five parameters affecting onhuman health, involving PM2.5, CO, temperature, humidity, and air pressure, have been considered as inputsfor the proposed fuzzy-based AQ model.

Results & Discussion
In Fig. 3, numerical results showed a good agreementwith experimental data. The IV performance curve of thedifferent flow fields is displayed in Fig. 4. The results revealedthat the 1S flow field provided the best performance,while the worst was found in the parallel. Although the1S flow field was also found the best in eliminating theliquid water, as seen in Fig. 5, the pressure drop (see Fig. 6)was found extraordinary high as compared to that of theothers. Therefore, the 1S flow field was not appropriate tobe used in a commercial scale since it requires a power tocompensate the pressure drop.
The number of channels affects the small-size PEFCperformance greater than the flow field designs since as thenumber of channels increases, the less amount of watersaturation, higher performance and pressure drop werefound. However, the influence of designs will be greater as thenumber of channels increases. With the same number ofchannels, the PIS flow fields performed better than theS flow fields as their geometry provided higher reactantflow velocity (see Fig. 7). Hence, the PIS flow fields were morepreferable than the S flow fields since a flow field with a highnumber of channels is required in a commercial scale fora lower pressure drop.
One of the key components of a polymer electrolytefuel cell (PEFC) is the reactant flow field and its bipolarplate since they perform several functions affectingPEFC performance, such as keeping the reactantsseparate from each other, distributing them to thecatalyst layer, distributing the electrons to the externalcircuit and also helping of water management.
An improper designed flow field of a polymer electrolytefuel cell (PEFC) can cause the maldistributions, resultingin the reduction of PEFC performance and lifetime.Although there are several researches investigatingthe effect of flow field design, the parallel in series flowfields, which are the commercial flow fields sold byElectrochem Inc., however, have received a very lowattention.Thus, the in-depth investigation of the parallelin series flow field has not yet been carried out.

Six flow field configurations in Fig. 1 were carefully selected byconsidering the geometric parameters affected on PEFC performance.So that this study can highlight the effect of the flow field designsand number of channels. The geometries were created on ANSYSWorkbench based on the realistic geometric parameters and importedinto ANSYS FLUENT to compute by using the add-on module.
Conclusion
The 1S flow field provided the best performance anduniformity while the parallel flow field was the worst.The design of the PIS, which slightly increased thepressure drop, would provide a higher reactant flowvelocity at the corners as compared to the serpentineflow fields with the same number of channels, andthus, it enhanced the water removal, resulting in thebetter water management. This effect is greater as thenumber of channels increases. This result is significantand would contribute an impact to the larger cell areaPEFC that used a much more number of channels flowfield to avoid the large pressure drop.
Objective
In this study, a numerical investigation on the distributionsin six different flow field designs (see Fig. 1) over 5 cm2 PEFC has been systematically carried out using CFDtechniques via ANSYS FLUENT software to study theeffect of different flow field configurations and numberof channels.

IntroductionA Three-wheeled vehicle so-called Tuk Tuk is one of Thailand’s cultural identities. The conventional Tuk Tuk usesinternal combustion engines (ICES) and releases greenhouse gases which causes the global warming. Replacing theconventional engine with an electric motor can be a promising solution to keep operating Tuk Tuk for Thai’s tourismand also reducing the pollutions. However, a major technological barrier which prevents the electric Tuk Tuk(E-Tuk Tuk) from the global commercial market is its too long recharging time, as compared with the gas refill timeof the conventional Tuk Tuk. Thus, instead of recharging it, switching the battery at a service station can be a goodanswer solving such problem.

Research Methodology
The battery switching system was initiallydesigned on CATIA software. To make thebattery switching system easy to be operated,an idea of cell phone-alike electrical contactswas employed for power transmission from thebattery to the motor. The designed electricalcontact consisted of Cu plate as the electricconductor, Bakelite as the insulator, and ironplate as the supporter, as shown in Fig.1.The relationship between contact resistanceand the force exerted on the contact was studied(Fig. 2) in order to determine the a proper forcerequired to achieve minimum resistance loss.Afterward, the battery switching system was designedto attach on the Tuk Tuk chassis with a rollersupport sothat it can be retrieved out of and pushed back inthe Tuk Tuk easily (Fig. 3 and 4). Simulation in ANSYSsoftware was preformed using finite elementanalysis (FEA) so as to analyze the strength ofthe E-Tuk Tuk structure under different inclinedplanes of 0°, 10° , 20° and 30°.
Conclusion
The prototype of an E-Tuk Tuk with a batteryswitching system has successfully developedas the switching operation can be carried outby a single person within 5 mins, i.e, 2.23 and2.83 mins for a male and a female, respectively.Moreover, simulation and experimental resultsprove that the structure of the designedE-Tuk Tuk is sufficiently strong and will notplastically deformed under daily-use conditions.
Results and Discussion
The minimum contact resistance of the coppers was found to beat about 0.01 under the load more than 0.15 MPa. As a result,springs with a stiffness of 25.6 kN/m were selected to generate therequired load. For the structural analysis, simulation results showedthan the maximum deformation approximately 3 mm in the normaldirection to the surfaces (Fig. 5). The stress distribution over the chassisat different inclined angles was also studied. Fig.6 presents the stressdistribution at the inclined angle of 30°, which was considered as thecritical operating condition. It was found that even at the risk areaswith maximum stress, the chassis will not plastically deform sincethe factor of safety was higher than 1.93. For a typical use scenarioof 0°, the safety factor was at least 2.33. Finally, the developedE-Tuk Tuk was experimentally tested that it can be operated safelyand efficiently as its battery switching process can be done within 5 mins.
Impacts to Society or Commercials
This project is the prototype of E tuk-tuk that can reduce pollutionand promote Thai traditional vehicle.

Results & Discussion
The result showed that Thailand has a usable area of1.8 million ha with a maximum potential yield of51 million tons/year. After the analysis was done, themost suitable area for Napier grass plantation, was inthe Northern region. Although it did not contribute asthe region of the largest usable area, it could providea high amount of Napier grass yield as compared to itsusable area. For example, the land suitability map ofPhrae province which is in the Northern region was shown in Fig. 2.
Research Methodology
According to the Alternative Energy Development Plan(AEDP 2012-2021) initiated by the Ministry of Energy (MoE),the future power generation sourced by alternativeenergy resources is planned to be increased up to 25%of total power generation in the next 10 years. Amongvarious alternative energy resources, biogas will contributeas high as 3600 MW of which 83% or 3000 MW will beproduced from Napier grass. By an approximateestimation, an enormous area of 480,000 ha throughoutThailand is needed for Napier grass plantation in orderto achieve the AEDP 2012-2021’s target.

ConclusionThe method of locating the suitable areas for Napier grassplantation over Thailand and its productivity estimationwas successfully developed. The total usable was 1.8 millionha or approximately 3.5% of total geographical area ofThailand. It was found that most of the usable areas werein the suitability classification of rank S2. Overall,the Northern region is the most suitable while the largestusable area were located in the North-Eastern regionwhich is approximately 45% of total usable area.
Impacts to Society or Commercials
This project identify the areas which are suitable forNapier grass ,one of energy crop , plantation over thecountry.
The maps of land use, soil and precipitation were used inthis study. Fig. 1 (b)-(d) presents an example of those 3 mapsof Phrae province, respectively. The land use map was setas initial governing map by which only the areas of anabandon field, an abandon farm, a pasture, a groove woodand a lower land were considered as the usable areasfor Napier Grass Plantation. By overlaying all 3 mapsvia ArcMAP 10.0 integrating with FAO framework of landsuitability, the suitable areas were qualitatively located,as shown in Fig. 2. Finally, the multiple regression analysiswas applied to the map so as to evaluate quantitativelythe potential of Napier grass yield in Thailand.

Students in Computer, Robotics and Technology ResearchLaboratory (CERT) spent most of the learning aboutelectronics and computer programming. These students
integrate everything they had learned to design and build
a basketball-shooting robot. TPA Robo’s BasketballCompetition 2017, held in front of a large, cheering crowd.The robot shoots as many basketballs as possible in undernine minutes. The winner of this competition is determined
by points acquired by the technical report. If two or more
teams are equal on points, the team with the shortestrecorded time to complete is the winner.
Encourage students to apply their science and technology
knowledge to create and build their own robots. - Design and build a basketball-shooting robot that can throw a free-throw shot accurately.
- Implement the engineering design process to solve the
design challenge.
- Broaden the students' potential ability to create whole new systems of robot technology.
