Minimal Number of Steps in Euclidean Algorithm and its Application to Rational Tangles

We define the regular Euclidean algorithm and the general form which leads to the method of least absolute remainders and also the method of negative remainders. We are going to show that if looked from the perspective of subtraction, the method of least absolute remainders and the regular method have the same number of steps which is in fact the minimal number of steps possible. This enables us to apply the theory in rational tangles to determine the most efficient way to untangle a rational tangle.Comment: 15 Pages. This project was supervised by Professor David Gauld (University of Auckland). This is my first academic paper, written as an undergraduate. Therefore, I would appreciate pointers and tips. It is going to be published in Rose-Hulman Undergraduate Mathematics Journa

Humidity control in different building applications; restaurant and operation theatre

Air conditioning (AC) in tropical climate required dehumidification of air at a low dew point temperature to meet humidity standard. This increase the required cooling energy and heating energy is needed to raise the supply air temperature to meet the room’s design temperature. This research was carried out to study energy efficiency and indoor environment factor in two different applications that is restaurant and operation theatre (OT). A method was proposed to enhance the humidity control and energy efficiency in the AC system by applying psychrometric analysis based on actual measurement. Three (3) different systems were used in this study that consists of economizer damper, desiccant wheel and heat pipe heat exchanger (HPHX).The economizer damper analysed base on fresh air intake requirement for ventilation purposes on standard ASHRAE 55 (2010). Manufacturing software by Novelaire and HPC were used to perform the psychorometric analysis for desiccant wheel and HPHX. At the restaurant, the grand total loads (Qt) of the existing AC system were 296.1 kW as to meet temperature and humidity level requirement. The Qt was reduced to 153.8 kW for economizer damper, 170 kW with heating 60.38 kW for desiccant wheel and 178.3 kW with heating 4.1 kW for HPHX. In actual measurement for the OT, the existing AC system had a grand total load Qt of 90.1 kW with heating 5.6 kW and it did not meet the humidity level requirement. However, the AC system required Qt 95.9 kW with heating 12.2 kW as to meet the humidity level requirement for an OT. By using the HPHX in the system, a reduced Qt of 81.6 kW with heating 17.7 kW was achieved, where as a Qt of 100.8 kW with heating 39.9 kW was attained by utilizing the desiccant wheel, whilst maintaining the humidity level requirement. The economizer damper was not applicable for the OT because the OT requires 100% fresh air intake. As a conclusion, damper economizer was beneficial for energy efficiency in restaurants with reducing of 48% energy used and HPHX was beneficial for energy efficiency with reduced 9.4% in OT compared with existing AC system

Abstract This article attempts to answer and explain how the process of regional financial management runs in a disaster emergency situation, namely the Covid-19 pandemic. In this case, the regional government, through one of its functions in managing regional finances, has full responsibility for being able to carry out the regional financial management process both based on statutory regulations and also taking into account regional needs. In a situation like this, the local government must be able to be careful and precise in carrying out regional financial management, especially in terms of refocusing and reallocation of funds in the APBD. Given that currently this process provides a new legal situation for local governments in managing regional finances. In addition, the government must also be able to build and ensure public trust, especially local communities, when local governments carry out the refocusing and reallocation process and the APBD as an effort to handle the Covid-19 pandemic because it involves the interests of the local community. By using the normative juridical research method, this article provides an analysis of how the process of refocusing and reallocating the Regional Budget in regional financial management can work well in accordance with statutory regulations and in practice. Then how is the public trust building strategy for regional financial management. Therefore, both in the context of regional financial management and the urgency of public trust in a pandemic situation, both must be implemented appropriately and wisely in meeting regional needs.

Development of Chemical Reactivity Hazard Tool For Process Safety System

The major hazards with which the chemical industry is concerned are fire, explosion and toxic release. All the hazard in the chemical industry can be relate to their reactivity. The reactivity plays an important role as the chemicals have their specific attributes of their own. So, in assessing the damage potential and causes or errors which have led to these disasters, an analysis has to be done. The impacts of reactivity in the process industries may be predicted based on the database. However, the applications of these models require competency in computer programming. Therefore, the objective of this project is to develop an application called the Chemical Reactivity Hazard System (CRHS), which is able to study the impact of chemical reactivity in the process industry. The CRHS application is developed using Visual Basic (VB) programming language. The develop software utilizing an established database for the chemical reaction in order to generate the result of hazards. With the reaction, the application shows the respective hazard codes and their description. . The software has been tested with few case studies and the results shows a good agreement with the other results from different softwares. The development of this software has been divided into four stages, which are planning the application, collecting the required database, writing the computer programme, and integrate the result into the software. The software is capable to estimate the reactivity hazard of chemicals in the industries and it is designed in a flexible way, so the users can add more chemicals if they did not find their target one. The hazard code will give us the data for tackle such problems if it occurs in the industries. It gives us the first layer of protection against the hazards. The CRHS application is useful and feasible because it is user-friendly, able to function as a stand-alone application and it is compatible with all windows operating system

Computerized System For Breast Cancer Monitoring And Grading Of Abnormality In Medical Thermogram

Breast cancer is the most common form of cancer affecting women in the world. With the advanced improvement in thermal imaging technology, dynamic digital thermography can be applied to medical procedures for early detection of many health conditions including breast cancer often before they can be picked up by standard medical tests. Digital thermography is a totally non-invasive, non-contact clinical imaging procedure that diagnoses abnormal areas in the body by measuring heat emitted from the skin surface and expressing the measurements into a thermal map called thermograms. It could assist in medical imaging procedure for detecting and monitoring of various diseases and physical injuries. The usage of breast thermogram as a detection tool of cancerous cell growth is being investigated nowadays. It can detect the cancerous growth in its early age, then later to be confirmed by mammography or any other technique. Mammography alone cannot detect cancerous cell in its early age and the usage of digital thermography alone cannot pinpoint exactly at where the cancerous cell location for further treatment, thus both of them work in harmony. This project attempts to ease the work of clinician to analyze data extracted from thermogram by developing a computerized system for early detection of breast cancer, monitoring and grading of abnormality in medical digital thermogram
