A Framework For Detecting Injected Influence Attacks On Microblog Websites Using Change Detection Techniques, Vishnu S. Pendyala, Yuhong Liu, Silvia M. Figueira

Computer Science and Engineering

Presidential elections can impact world peace, global economics, and overall well-being. Recent news indicates that fraud on the Web has played a substantial role in elections, particularly in developing countries in South America and the public discourse, in general. To protect the trustworthiness of the Web, in this paper, we present a novel framework using statistical techniques to help detect veiled Web fraud attacks in Online Social Networks (OSN). Specific examples are used to demonstrate how some statistical techniques, such as the Kalman Filter and the modified CUSUM, can be applied to detect various attack scenarios. A hybrid data set, …

Hedhi Help, Sarah Pagnani, Kelsey Pasco, Brandon Smith, Sarek Sotelo-Jimenez

Computer Science and Engineering Senior Theses

A culture of social taboos and silence leaves many young women beginning menarche in isolation, without complete understanding of the changes occurring in their bodies. There is a widespread stigma surrounding menstruation all around the world. These stigma impose significant barriers to education and proper hygiene for young girls during a critical time in their lives. Not having the proper support and resources to manage this process, 1 in 10 girls in sub-Saharan Africa miss school during their period, and therefore are more likely to drop out altogether. In Kenya specifically, menstruating girls miss an average of 4.9 days of …

Virtual Museum For Nacha, Sonali Chaudhry, Alisa Hawthorne

Computer Science and Engineering Senior Theses

Our team worked with the Nso’ Arts and Cultural Heritage Association and created a virtual museum in order to increase awareness of the unique culture of the Nso’ people in Cameroon, Africa. A lot of information from this region is in danger of being lost due to political tension and poor artifact conservation, and many people, including the Cameroonian youth, are not prioritizing the preservation of their culture and history. Creating a website where individuals can view the art, history, and culture found in Cameroon is the best way to increase the availability of knowledge of the Nso’ people. Such …

Cervis: Cervical Cancer Early Response Visual Identification System, Evangelia Bouzos, Ivy Fernandes, Marina Predovic

Bioengineering Senior Theses

Our goal is to make a positive impact in the cervical cancer diagnostic space through the development of an accurate, cost effective solution that enables women in low resource settings to test for cervical cancer on a frugal and effective platform. In developed countries, we rely on regular preventive care, such as pap smears, to identify any cellular abnormalities that may indicate the disease state. However, due to the high cost and laboratory requirements of this procedure, women in low resource settings typically do not have access to this procedure. Since they are not regularly screened and often have little …

Meshr: A Modular, Economical Skin Graft Hand Roller, Maggie Alt, Josée Fournier, Madeline Krenek, Will Paton

Bioengineering Senior Theses

In South Africa and around the world, the rates of severe burns are a significant health issue. Skin grafts are used to improve the function and appearance of the burned area and reduce the amount of time a patient is in the hospital. To minimize the amount of skin needed and maximize the coverage of the graft, the harvested sample is meshed in a lattice pattern so it can expand and graft a much larger surface area. Unfortunately, the current methods and devices used in both high and low-income countries have been optimized for hospitals with larger budgets and more …

Milkguard: Low-Cost, Polymer-Based Sensor For The Detection Of Escherichia Coli In Donated Human Breast Milk, Maggie May, Nicholas Kikuchi, Matthew Zweber

Bioengineering Senior Theses

Breast milk, the gold standard for infant nutrition, could prevent up to 13% of child deaths worldwide. However, many mothers are unable to breastfeed due to health conditions and other factors. Because of this, a network of more than 500+ human milk banks, which collect and distribute donated breast milk to infants, have emerged worldwide. However, operational costs to ensure the safety of this milk remain time-intensive and costly.

There are no existing diagnostics for rapid and on-site detection of bacterial contaminants in donated milk. Currently, many milk banks send samples to outside laboratories for bacterial culturing tests, which take …

Climate Smart Farming For Women In East Africa, Lauren Oliver, Cristina Whitworth

Civil, Environmental and Sustainable Engineering Senior Theses

According to the United Nations Food and Agriculture Organization, 60% of East Africans live as subsistence farmers. This population is particularly vulnerable to the effects of climate change which has increased the duration and intensity of droughts and floods. Droughts and floods can destroy an entire season’s harvest, causing sustenance farmers and their families to struggle for food until the next season. In an attempt to mitigate the severe effects of climate change on these farmers and reduce food insecurity in East Africa, the team has designed a small-scale aquaponic farming system that simultaneously grows fish and vegetables. This system …

Low Cost Sms-Enabled Ekg For Use In Developing Countries, Gabriel Christ, Shachi Kakkar, Michael Mcelroy, Augustus Boling

Interdisciplinary Design Senior Theses

According to official estimates, cardiovascular disease will become the leading cause of death in the developing world by 2020 [1]. This makes regular screening and early detection a priority for these regions. At present, such screening relies on stationary electrocardiogram (ECG) machines, but this technology has several drawbacks. Most machines are costly, stationary, and require a physician onsite to collect and interpret the data; as a result many isolated rural communities lack access to basic heart disease screening. In order to better meet the screening needs of these populations, we propose a twopart solution involving a simplified, inexpensive ECG device …

Smart And Sustainable Aquaponics, Ryan Toal, Kevin Claggett, Justin Goh

Electrical and Computer Engineering Senior Theses

As the global population increases, new ways of sustainable and efficient food production need to be explored in order to meet the growing demand from society. In this paper we explore the methods and functionality of an off-grid, semi-autonomous aquaponics system. This system will serve as a proof of concept for a large scale aquaponics system which can be modelled in other parts of the world where arable land is scarce. It was found that though the initial startup costs are high, it will be able to reduce the cost of food in the long run. The system implements a …

The Solar Microgrid Project In Togo, Christian Jason Wintery, Alexander Mayorkis

Electrical and Computer Engineering Senior Theses

Danyi Mempassem, Togo, Africa has villagers in need of electricity, however, they cannot afford to put in the infrastructure and then pay the steep cost of energy from the government. The best option for energy for the village is an affordable and renewable resource but due to limitations of geography the only viable option is a photo-voltaic system. We designed a working solar microgrid tailored for the location and weather of the village which can support all of the lights, cell phone chargers, and televisions that the villagers need/desire while being reliable, sustainable, safe, and affordable. The design and implementation …

Taking Afrobarometer Data Everywhere, Christen Nguyen, Sean Thomas, Adrienne Tina

Computer Science and Engineering Senior Theses

According to statistics gathered by research group Afrobarometer, many countries in Africa lack infrastructure and basic necessities. In fact, Afrobarometer knows the specific rates of need and availability sampled across thirty-six countries but more prosperous African countries do not know these numbers. These more developed countries are in a position to help their less fortunate neighbors if only made aware of the social and economic climate in the respective areas. Our partnership with Afrobarometer will allow us to advertise these statistics through the use of a mobile application. The data will be displayed in a way that is easy for …

Garbage Beam, Paula Back, Mariela Murillo

Civil, Environmental and Sustainable Engineering Senior Theses

Located in a hot desert climate area prone to strong winds, Egypt is made up of many homes with little to no roofing leaving civilians exposed to the harsh elements. The overarching goal of this project is to provide these homes with efficient and affordable roofing using concrete with common garbage materials as reinforcement. Through preliminary testing and tensile testing it was possible to narrow the focus down to two reinforcement materials: fish netting and plastic grocery bags. From there final beam testing and pull out testing successfully demonstrated the promise of these materials. With this, however, it is still …

Climate Change And The Delta, San Francisco Estuary And Watershed Science, Michael D. Dettinger, Jamie Anderson, Michael L. Anderson, Larry R. Brown, Daniel R. Cayan, Edwin P. Maurer

Civil, Environmental and Sustainable Engineering

Anthropogenic climate change amounts to a rapidly approaching, “new” stressor in the Sacramento–San Joaquin Delta system. In response to California’s extreme natural hydroclimatic variability, complex water-management systems have been developed, even as the Delta’s natural ecosystems have been largely devastated. Climate change is projected to challenge these management and ecological systems in different ways that are characterized by different levels of uncertainty. For example, there is high certainty that climate will warm by about 2°C more (than late-20th-century averages) by mid-century and about 4°C by end of century, if greenhouse-gas emissions continue their current rates of acceleration. Future precipitation changes …

Bringing Electricity To Alafiarou: The Solar Microgrid Project, Nicolas Metais, Jacob Leatherberry

Electrical and Computer Engineering Senior Theses

Despite the great technological advancements and discoveries that have been made throughout the last century, 1.2 billion people still live without access to electricity, 95% of which live in Sub-Saharan Africa and developing Asia.1 In this paper, we discuss how we designed and implemented a self-sustaining, affordable and highly replicable solar microgrid in order to accelerate the electrification of rural communities in the most environmentally conscious way possible. Our project focused on developing a microgrid for a small community of 10 households in rural Benin that previously had no access to electricity. We travelled to this village in December of …

Rise Above The Flood: Bridge Building In Gambibgo, Ghana, Vanessa Diaz, Ariana Govan, Matthew Millsaps

Civil, Environmental and Sustainable Engineering Senior Theses

This thesis focuses on the design of a steel girder bridge for a rural community in Ghana, Africa. While Santa Clara Civil Engineering Senior Design Teams have been working in this community since 2008, it was not until 2013 that a project team attempted to design a pedestrian footbridge. After the 20152016 project team decided to take on the project, it became clear from talking with the Ghanaian Municipal Engineers and local community members that the steel suspension bridge proposed by the 2013 team would not meet all the needs of the community. Therefore, the team redesigned the bridge, proposing …
