This project had one purpose: creating almost unbreakable encryption by breaking a Caesar – and Vigenère Cipher and getting familiar with how they work. Created a program to encrypt and decrypt messages with a Caesar Cipher and Vigenère Cipher encryption. Breaking these encryptions in these programs will help to identify the factors that contribute to strong and weak encryption systems. A program was created to encrypt messages using Caesar Cipher with a key from 1 to 25 and decrypt messages without knowing the original key by doing different types of “attacks” on the system: a brute force and frequency analysis attack. Created another program to encrypt messages using Vigenère Cipher with a keyword or keyphrase and decrypted messages whilst knowing that original keyword. Tested and compared the two different cyphers when being attacked. This helped identify factors that influenced the strength of encryption and identified the advantages and disadvantages of each Cipher as well as the weaknesses in each attack. Through testing and breaking a Caesar and Vigenère Cipher successfully, multiple factors were identified that influenced the strength of the encryption system. These were used to ensure the new encryption created will be as strong as can be. Comparing the success rate of the different attacks on each Cipher, the similarities, weaknesses and strengths in the Brute Force and Frequency Analysis attacks were found.

In 2565 B.E., 泰國's elderly, comprising 18.3% of the population at 12,116,199, faced health challenges, with diabetes, cerebrovascular disease, arthritis, and lung cancer prevalent. Caregiving hurdles arose as many family members worked outside, impacting the care of elderly individuals with these conditions. To address this, the "SVMR Medication Reminder and Care Robot for the Elderly" was developed. Known as the Smart Versatile Medication Robot (SVMR) or "New Robot," it serves as a user-friendly solution for home-based elderly care. Recognizing the adverse effects of missed medication on health, the SVMR system, combining hardware (New Robot) and software (Application), aimed to alleviate caregiving burdens. The New Robot's hardware includes a customizable medication reminder system, a video call system, closed-circuit camera system, doctor's recommendation display system, and an SOS system for emergency assistance. The Application complements this with features like medication schedule setting, video call communication, activity tracking, daily schedule management, and live camera monitoring. During the SVMR prototype trial, one unit was tested, with developers' relatives trying the medication dispensing system. Positive results emerged, showcasing improved medication adherence among the elderly and affording caregivers more time for other responsibilities. Satisfaction levels, as assessed through interviews, were notably high. Elderly feedback suggested the need for additional compartments for different medications and enhanced notification methods, particularly when they were not in proximity to the medication cabinet. In essence, the SVMR system provides a comprehensive solution to the challenges faced by households with elderly members, ensuring better disease management, increased medication adherence, and support for caregivers, all within a concise and user-friendly framework.

在今日，電路板被廣泛運用各大領域，而電路板上錫球在焊接的過程中有可能會產生瑕疵，因此我們需要找到一個方式來檢驗電路板上錫球是否有瑕疵。有很多方式可以進行，例如: ART (Algebraic Reconstruction Technique)、SART (Simultaneous Algebraic Reconstruction Technique)和 FBP（Filtered Back Projection），ART、SART 為疊代型的方法，疊代型比較準確但花費較多時間，與之相比，FBP 利用反投影法，能節省許多時間。本實驗嘗試利用 FBP 得到電路板上錫球的269張切片圖，利用 ImageJ 將所有圖片疊起來以得到3D 圖並探討錫球是否有缺陷，之後採用不同的種類濾波(filter)進行測試並利用 ImageJ 分析比較各 filter 的特色，高通濾波器如 Ramp filter 主要強化圖像邊緣，低通濾波器如 Hann filter 主要強化圖像中低頻的部分，使影像對比度變高，分析比較後嘗試自己建立 filter，此 filter 結合了 high pass filter 與low pass filter 的優點，影像的對比度變高的同時，錫球的輪廓也更明顯。

影像對位(Image Registration)為重要影像處理工具，目前已經廣泛運用各個領域，從影像醫學偵測與診斷、工業製造、品管檢測、臉部辨識都是電腦對位的應用。本次研究將探討機器人影像對位，分別透過不同影像感測器來擷取外部影像資訊，透過對位系統進行目標 物瞄準。在準確性分析研究發現不論是單一定點或是連續三點分析 結果顯示感應器的Cpk 未達1.33。此外，分析過程中發現Vision sensor 的 Cpk 值高於 GPS，顯示 Vision sensor 在影像對位準確性表現性上優於 GPS。在時效性分析方面，感應器的種類與底盤齒輪組對於影像對位時間無顯著差異，在連續三點實驗發現時效性與偵測的地點達 顯著差異。研究結果顯示在未來自駕車的設計可以將影像對位與辨 識功能結合，透過感測器觀察外界影像資訊，結合機器學習與演算法， 提高辨識率及時提供行車資訊，提高道路安全與成員安全。

汽、機車呼嘯而過的排氣噪音經常造成周遭民眾的困擾，為杜絕這種狀況，環保署於2021 年開始推動「聲音照相科技執法」，透過包含魚眼攝影機、車牌辨識攝影機等設備的整合，來紀錄行經車輛產生的噪音是否超過管制標準，不過此系統目前仍存在一些限制，如:當多台車輛同時經過時無法辨別確切的噪音來源，而需要人工判定。本研究旨在利用聲源定位原理結合影像辨識技術，實作出一套能夠追蹤聲源（噪音）並辨識聲音來源（車輛）的聲音照相系統，期日後能實際應用並解決道路上多車輛時無法辨識噪音來源的困擾。研究中提出一套能透過遠端控制程式，將收音裝置、攝影設備和資料分析軟體等各項軟硬體設備，串聯成自動化追蹤聲源的系統設計方案。

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.

Our vision aims to raise the quality of life and we had planned smart cities from scratch but what about the current cities the residents of Riyadh suffer from extreme traffic and spend hours circling the block searching for a open park which wastes time money and is bad for the environment. 30-50% of traffic is causing by not being able to park and due to Riyadh lack of proper city planning and radid increase in inhabitants especially after allowing women to drive and as the car being the main way of transportation finding a open park could be a nightmare for some. We have approached this problem from the technological perspective by developing a free application for Riyadhs inhabitants that's main goal is to navigate each driver from their current location to the best open park possible in the shortest time possible but what dirstinguishes us from similar apps in the literature is that we provide the time of departure for each park as well as the ability to book suck parks even if it is ahead of time via a interactive live map. The technology's that we used are the cellar censor that will track the users location and the ultrasonic sensor to track the occupancy of the parking in case the driver doesn't have the app but in which case will case will not be able to provide booking features. We have struggled in the lack of expertise and experience and in motivating the drivers to input correct data about there time of departure we also didn't have enough time to validate our project For future work we will validate our project and we plan on making the detection of the time of departure automatic as well as vobering all kinds of parks. We plan on expanding the scope of target users to include institutes as well because with time the app will have collected enough data to help institutions provide better parking such as ruch hours parking scope percentage of booked parking etc we also plan on benefiting more from the cellular secsor to link data with the persons phone like certain access to private parks like disabled parking or home parking or private hotel offices parking etc
