Fortification of Seabed in Marine Structures
No full textIn various cases, liquefaction around a marine structure can bring disastrous consequences to the overall structure. The highest cause of liquefaction involves the instability of the seabed which leads to the creation of slopes and brings the structure to collapse when earthquakes occur. Our focus will involve finding solutions to stabilizing/reinforcing the seabed. In addition, planning should begin by selecting an environment where earthquakes are not frequent and selecting a coast that is not shallow to try and improve the stability of the seabed. We are focusing a lot more on the stability of the seabed because marine structures must deal with many waves that can cause liquefaction within the seabed, leading to instability in the structure.Civil and Environmental Engineering, Department ofHonors Colleg
Modelling of Liquefaction Around Marine Structures
No full textThe utilization of marine environments for various industrial and energy-related purposes has surged in recent times, leading to the construction of numerous structures along coastlines and offshore locations. However, these structures face a significant threat from liquefaction, a phenomenon wherein solid soils, in this case, seabed, lose their strength and behave like liquids under stress. Understanding and accurately modeling liquefaction around marine structures is of prime importance to ensuring their safety, longevity, and operational efficiency. This research has for purpose the exploration of the complexities of liquefaction phenomena in marine environments, with a focus on modeling techniques and methodologies. Through a holistic literature review and analysis of case studies, the study aims to elucidate the underlying mechanisms of liquefaction and its implications for marine infrastructure as well as study current efforts to model seabed liquefaction. Additionally, this research serves as an educational endeavor, fulfilling the requirements of CNE 3322: Legal Aspects of Construction Engineering. Overall, this report will outline the significance of modeling liquefaction around marine structures, emphasizing its importance in engineering practice.Civil and Environmental Engineering, Department ofHonors Colleg
The Role of HydroDiesel in Sustainable Development and Economic Growth

Sustainable fuel production underpins the global economy, promotes energy security, enriches communities and enables environmental stewardship. Our research aim to investigate how producing HydroDiesel+(Rights Reserved) can create new economic opportunities. Reducing specific fuel consumption and harmful emissions, while boosting diesel engine performance are all issues that this project hopes to tackle. While widespread supply chain issues have crippled the economy over the past two years, the efficient supply chain framework of HydroDiesel+ (Rights Reserved) is discussed.Construction Management, Department ofHonors Colleg
AI-Driven Flood Forecasting and Response System
No full textNatural hazard risks appear to be increasing due to the climate constantly changing. The effect of not being prepared for a natural hazard can either be minimal or could result in a natural disaster. Although we cannot prevent natural hazards/disasters from happening, we can, however, be prepared. Technology has become so advanced that we have access to real-time data analysis which in turn helps us make decisions more efficiently. Machine learning technology such as weather radars and satellite imaging can prepare us early for natural hazards such as hurricanes, storms, floods, and other natural hazards. These machine learning technologies can also help evaluate a disaster's location and the degree of the damage leading to having a more effective disaster response operation. Machine learning is a subset of AI, which has provided many new advancements in assessing patterns and algorithms associated with natural hazards. With the use of these new techniques, we can build optimized prediction models that analyze datasets and trends at a higher response rate as opposed to traditional methods. In regard to Natural Hazard Management, this provides the solution to increased response times and preventative measures.Civil and Environmental Engineering, Department ofHonors Colleg
Artificial Gecko Skin: Harnessing the power of Van der Waal's Force in Shear Systems
No full textArtificial Gecko Skin was developed in 2010s by Stanford professor Dr. Mark Cutkosky in response to a competition to design, build and test a climbing robot in a vertical environment. To achieve this Dr. Mark Cutkosky was inspired to mimic a gecko's feet. After researching the physics of how a gecko climbs, he found some amazing realities. Geckos do not use suction cups. Nor do they have little hairs or spikes. Their feet have little spatula which are a few nanometers in dimension. This allows for an extremely small point of contact giving the gecko the ability to obtain an extremely close contact with the material it is climbing. This contact is so tight it is called an adhesion. Dr. Mark Cutkosky's research shows the gecko leverages the molecular Vander Vaal’s force at the atomic level. Geckos achieve this considerable bond by use of an extremely week molecular bond. Dr. Mark Cutkosky created a crude approximation of artificial gecko skin using molded silicon. He has successfully used his silicon gecko skin in robotics to pick up extremely delicate objects using a small force normal. This artificial material when loaded in shear creates enough surface area of contact to hold up an object. Perhaps the most amazing feature of this silicon gecko skin is that is not a glue or suction. When the lifting force is released the gecko material effortlessly lets go of the object. By integrating gecko material into repeatable processes much time and energy could be saved.Civil and Environmental Engineering, Department ofHonors Colleg
King Solomon's Temple a Cornerstone for Modern Construction
No full textHistorians believe the traditional construction began to take shape in Ancient Egypt, Mesopotamia, and the Achaemenid empire. However, there is no specific building or area that can be marked as the beginning of modern construction. As the world constantly advances, we need to understand that modern technology and practices have evolved from prior principles and guidelines. Engineers today need to understand the principles that have laid the foundation for contemporary construction, and how they have developed over the years. King Solomon’s temple is a perfect example of a structure that embodies these principles to which we still practice. As engineers, we begin to analyze this building to understand how it came to be by asking questions like, how the structure was built, what planning went into making it possible, why the material selection was so important, and how they were able to transport these materials with limited technology at that time. These questions are important because they help set fundamental reasoning and similarity with modern-day construction. This study discusses the key construction methodologies of how antiquity serves as foundations of modern construction such as prefabrication.Civil and Environmental Engineering, Department ofHonors Colleg
Reduction of Carbon Emissions Generated by LNG Storage
No full textLiquified Natural Gas (LNG) has great potential to be a critical resource in the transition from fossil fuels to cleaner energy production and primarily consists of Methane. While storing Natural Gas as a chilled liquid is beneficial because the reduction in volume allows for more LNG to be stored, there are problems arising from this process. Namely, LNG will boil-off due to small leaks and releases harmful Methane into the atmosphere. A team of researchers at MIT researchers proved the ability of zeolitic materials to successfully transform Methane (CH4) into a less potent greenhouse gas, Carbon Dioxide. As such, there is additional work needed to address the production of Carbon Dioxide (CO2). My research aims to remove these carbon emissions by developing a system that can be directly integrated to LNG storage vessels. This subsystem can be described as an enclosed volume containing highly efficient flora with an array of sensors to detect gaseous emissions, such as CO2. These components are integrated through an autonomous operating system that will first monitor emission levels and then vent the system once the CO2 gases have been converted to O2.Civil and Environmental Engineering, Department ofHonors Colleg
Are Hempcrete Blocks a Reliable Replacement in the Construction Industry?
No full textIn today’s climate, most people understand that global warming continues to be a prevalent issue within our society. However, many people are unaware of just how much the construction industry contributes to this problem. While in total, buildings generate nearly 40% of global CO2 emissions, 23% of that emission is due to materials like concrete, steel, and aluminum. (Architecture, 2020). With such a high carbon footprint like this, it is evident that the materials we choose need to be more sustainable. Hempcrete blocks are a rising alternative to modern-day materials due to its lightweight, thermal, and sustainable qualities. Hempcrete is made from dried hemp stock and lime, making it an eco-friendly replacement for concrete blocks because its production process does not create pollution. Hempcrete by itself is a weaker building block than concrete, however, there is now a method that integrates an internal biodegradable structure to the hempcrete that allows it to achieve the same resistance strength as concrete. Overall, this report explores the production, uses, and comparisons of hemp blocks to other materials.Civil and Environmental Engineering, Department ofHonors Colleg
