本研究改編自2015 EGMO P2，探討在𝑛×𝑚的棋盤中放入最多的1×𝑡或𝑡×1的骨牌，並使得每一個𝑡×𝑡還有空間再放入一個骨牌的方法數。原本題目是𝑡=2,𝑛=𝑚為偶數的情況。於是我先從𝑡=2開始研究，推導出(1)𝑛,𝑚皆為偶數、(2)𝑛,𝑚一奇一偶、(3) 𝑛,𝑚皆為奇數的答案。接著再推廣到(4)任意的𝑡且𝑡∣𝑛=𝑚的結果。最後再討論(5)𝑛,𝑚分別為𝑡的倍數、模𝑡餘1的數，或其他 數等不同可能性得出的不同答案。

本研究以對偶圖的性質，取代以往著重點或邊數量的方法，探討平面圖中漢米爾頓迴圈的存在性。我們設計一套定理，判斷對偶圖對應之原圖是否存在漢米爾頓迴圈，並提出「T 搜索」，有效降低電腦計算的時間複雜度。此外，我們建立多項化簡定理，能在不影響迴圈存在與否的前提下，透過邊、點的替換與收縮，或圖的結構分解來簡化圖形。研究中也討論 Herschel Graph 與 Tutte’s Graph，並提出當圖中出現特定結構時，原圖不具漢米爾頓迴圈的判別條件。最後，成果可用於構造具漢米爾頓迴圈平面圖之對偶圖，並期望數學方法推導出無漢米爾頓迴圈的平面圖，或用電腦窮舉所有無漢米爾頓迴圈平面圖之對偶圖，以便延伸討論。

Conspiracy theories are generally perceived as irrational, absurd and as having a negative effect on our reputation. Yet some people do not see them as such. This may lead us to wonder why and how an individual would come to believe or support such statements. In this work, the primary goal is to obtain the level of absurdity of various conspiracy theories so that they can be used in experiments designed to test Williams' “Strategic Absurdity Hypothesis”. In addition, this study attempts to demonstrate the link between conspiracy mentality and feelings of ostracism. In this research, I analyzed a group of 47 participants recruited via social networks in May 2023. The survey collected their demographic information, their conspiracy mentality, their feeling of ostracism, their knowledge of conspiracy theories and their perception of absurdity toward them. The results were analyzed using correlations and linear regressions. The results show a negative correlation between conspiracy mentality and the perception of absurdity for most theories. In other words, the higher a participant's conspiracy mentality, the less absurd the theory is perceived to be. Therefore, hypothesis (I) is partially supported. On the other hand, hypothesis (II), which says that ostracism predicts conspiracy mentality, is not supported by the results. These results are in line with Williams' “Strategic Absurdity Hypothesis” and Sterelny's signaling theory, explaining that an individual, by expressing agreement with a conspiracy theory typically perceived as absurd, damages their reputation in the eyes of others to show that they belong to the group. However, for the theories relating to COVID-19 and climate change, the conspiracy mentality does not predict the vision of absurdity, suggesting that their currentness and media coverage influence whether they are used as signals. The literature does not fully agree with our results and still presents very divergent opinions regarding the links between feelings of ostracism and conspiracy mentality. Indeed, it remains difficult to determine whether conspiracy mentality influences ostracism or vice versa. In conclusion, this study provides new ideas for future research on the origins and impact of the conspiracy theories.

工業環境中揮發性有機化合物(VOCs)的洩漏不僅危害人體健康，更可能導致工安事故。現有氣體感測器常存在選擇性低、反應時間長等限制。本研究開發高選擇性與快速反應的奈米材料導電式氣體感測器，以實現即時監測。 研究中合成並測試六種銀奈米 (Ag-MPC)材料：Ag@C6、Ag@C12、Ag@C16、Ag@MCP、Ag@C12/MCP及Ag@C12/MBT複合材料。在500-5000 ppm濃度範圍內偵測1-丁醇、正辛烷及間二甲苯等目標氣體的電阻變化。實驗結果顯示，Ag@C12經官能基修飾後，對1-丁醇具有明顯的選擇性。我們開發基於Arduino微控制器的即時監測系統，透過運算放大器電路實現高精度的電阻變化檢測。可以在工業環境中持續監測VOCs濃度並即時示警。未來將著重於優化訊號放大電路、開發新型官能基修飾材料、實現複雜氣體混合物的組分分析。開發成本低、反應快、選擇性好的感測系統，為工業安全監測領域提供實際應用價值。

Previous research observed increased TNTs formation between hypoxic and normoxic neuroblastoma cells, aiding hypoxic cell survival. CHGA was identified as a potential factor in this process. This study compared CHGA expression and whether CHGA exists in TNTs in five cell lines, with SH-SY5Y showing the highest levels, followed by SK-N-BE(2)C, while the other three showed lower expression. Future studies will focus on the impact of CHGA on cell survival and its mechanisms.

This research presents a novel approach to understanding the curling and uncurling behavior of tracing paper when exposed to water, identifying limitations in traditional diffusion-based models like Fick’s second law. While Fick's model adequately represents the uncurling phase, where water content is stable, it falls short during the curling phase due to its inability to account for dynamic changes in diffusivity. Our study identifies capillary action, modeled through Richards' equation, as the primary mechanism in the curling phase, where diffusivity varies with water content due to capillary-driven water movement through the paper's porous structure. Experimental data align well with the Richards' equation model, highlighting a saturation point where curvature peaks, governed by evaporation's impact on moisture balance. To simulate this phenomenon, we developed a finite difference approximation scheme based on Richards' equation, discretizing the spatial domain for detailed control over moisture dynamics and incorporating the Robin boundary condition with virtual points. This approach, combined with evaporation considerations, produces simulation results consistent with observed data, emphasizing evaporation’s role in steady-state moisture gradients and the subsequent deformation mechanics. Our findings further reveal that factors like paper thickness, temperature, and salt concentration significantly influence curling behavior. We established linear correlations between peak time and thickness reciprocal, as well as between peak curvature and thickness squared, supporting theoretical models. Temperature affects both peak curvature and curling rate due to changes in viscosity and surface tension, and higher temperatures prevent full uncurling due to sustained evaporation effects. Increased salt concentration heightens peak curvature without altering expansion ratio, suggesting additional variables in play.

Throughout our generations, a traditional system has been implemented for registering student attendance, in which the teacher is responsible for carrying out said activity, investing an average time of 15 to 20 minutes, which are part of the time of class. The objective of this project is to optimize this process, thus achieving effective class times, promoting the use of digital tools and innovation in teaching practice, in addition to generating security and confidence in tutors through the use of a service of message, which will notify the student's attendance in real time. Through a survey of the teaching staff of the CONALEP 338 Córdoba campus, it was detected that each teacher has academic loads equivalent to 3 to 5 modules per day, with an average of more than 40 students assigned to each module. Based on this information, the use of technological tools will be promoted and this process of teaching practice will be innovated with zero costs.

As of 2021, there are 368 harmful algae blooms and over 6000 invasive species in the United States of America. Furthermore, it is reported that the United States spends more than 11.1 billion dollars per year on clean-up methods for marine debris. However, there currently isn’t a method to monitor aquatic problems simultaneously, autonomously, and efficiently, creating a capability in the aquatic biosecurity sector. To combat this, we have created an autonomous vehicle that can conduct long-term monitoring of freshwater bodies for up to 60 hours.

Wind energy is one of the most promising and rapidly growing sources of renewable energy, although maximizing its efficiency while minimizing noise remains a challenge and limits its widespread adoption. The emergence of toroidal propellers, which have gained popularity for producing comparable thrust levels to traditional drone propellers while producing less noise, could mitigate this. This study aimed to develop a small-scale toroidal HAWT and compare its power and noise output to a conventional rotor design under similar wind velocity conditions. 15-centimeter diameter models of the toroidal and conventional rotors were created in Fusion 360 and simulated using Ansys Fluent to identify the significant aerodynamic characteristics that positively affect the blades’ power coefficient. The toroidal design with the greatest simulated power output at low tip speed ratios (TSRs) was then 3D printed and physically tested in a wind tunnel against the control rotor. The experimental results confirmed that the toroidal design had greater power coefficients at lower TSRs compared to the control rotor. The toroidal rotor started operating at a wind velocity of 3 m/s compared to the control rotor’s 6 m/s, which indicates superior start-up characteristics. While the toroidal rotor produced half the power output of the control at the highest tested wind speed of 7 m/s, it emitted 18 decibels less noise and showed a reduction in discernible noise between frequencies of two to five kilohertz. The results from this study show its potential in low-noise wind turbines within low-wind velocity environments.
