Computer Engineering

Faculty Advisor: Dr. Hamid Mahmoodi

The purpose for this project is to allow players, both new and professional, to practice on their shots to provide consistency in their game of billiards. While there are some designs of this simulator being developed previously, they make it too complex for users at home to setup and program. The goal here is to make a simplified code that runs the simulation smoothly and also provide cost efficient setup. There were many preliminary designs, both for physical and programming, but the final design was chosen due to simplicity and understandability.

Computer Engineering

Faculty Advisor: Dr. Thomas Holton

Our project is the design, development and production of an adventure platform side-scrolling video game for the iOS mobile platform. The problem with the majority of apps is their lack of clear to navigate user interface; as a result, we created an intuitive app for the average mobile playing gamer. To improve the user’s experience with the UI we integrated all aspects of computer engineering to create an app that is easy and enjoyable for the user to use. Resulting in an experience that leaves the audience feeling like they can pick up the game quickly through the use of heavily debugged code and clear minimalistic layouts. The app aims to improve a user’s experience with the UI.

Myo Armband MIDI Controller

By: Mitchell Jones, Tommy Do, and Mustafa Durrani

Electrical Engineering

Faculty Advisor: Dr. Thomas Holton

The goal of the project is to create an interactive and real time MIDI controller that is controlled by body movement. The MYO armband enables us to take positional and gesture data from your arm and hand movements and map them to digital synthesizer potentiometers. The most basic form of this implementation would be a "theremin" like device in which you can control parameters such as pitch and volume by moving your arm. However, seeing as though the MYO data can be assigned to any controls within the music software, we can control other parameters like song tempo and trigger samples to play by clenching your fist. Our end goal for this project is to showcase a couple of different examples of the MYO's ability to control music and sound and hopefully, in the process, inspire other students to see the unlimited potential uses of the MYO armband.

Computer technology is rapidly changing our world. With the new products coming to the market every day and up-gradation of exciting technologies, life is becoming easier and easier. Computer technology is everywhere we see, from schools to homes and from offices to hospitals. So the idea is take a simple product such as shower system and enhance it by upgrading and digitizing the system and hence creating a digital shower system. There were many different products that were studied though shower system stood out from them all. The state of California is going through drought conditions and it is very important to save water as well as cut-down on the waste of clean water. There are other automatic shower systems that are available in the market but they are not affordable for everyone.

Seismic Reliability of Code Designed Steel Plate Shear Wall Structures

By: Benjamin Kean and Shihang Guo

Civil Engineering

Faculty Advisor: Dr. Cheng Chen

Steel plate shear walls (SPSW) are a structural system used for resisting lateral loading. The system consists of beams and columns which act as the boundary elements and a thin infill steel plate. Current design specifications require the design of the SPSW systems to resist 100% of the structures story shear in the web plates neglecting the resistance capabilities of the boundary elements leading to overly conservative designs. For our research 3, 6, and 9 story structures were designed using a demand capacity approach for designing the boundary elements and web plates to resist 100%, 85%, and 65% of the story shear. To determine the response of the structures in a seismic event 44 ground motions of varying intensity were simulated on the structures and the response of the structures were determined using the finite element analysis program OpenSees.

Timberwolves Timber Bridge Team

Civil Engineering

Faculty Advisor: Dr. Timothy D'Orazio

The idea behind the design is to be able to construct a bridge adequate enough to hold the required load. Entering the bridge competition we tried to design it different from the other previous students, to be more unique. So we use a design concept of a suspended bridge and a truss bridge. We originally designed our timber bridge as a walking bridge. We used 4x6 beams to transfer the whole load to the posts or columns which the load is transferred from the 3x6 joists and then transferred from the 2x6 decking members where all the weight is being loaded on. We then used a unique design for our arch that is connected to the beams with 4x4 posts and 3/8" cables to help hold up the load so that there will be less deflection on the bridge. We use steel plates to connect the arch members together then using more plates to connect the arch to both the posts or columns and to the beams. We used wood screws to connect the deck members to the joists, and used L brackets to connect the joists to the beams. We had to drill 1/2" holes into the arch and the beams so we could screw in the I-bolts that will be used to connect the arch to the beams by using galvanized steel cables.

NATIONAL TIMBER BRIDGE DESIGN COMPETITION 2014-2015

By: Marc Salgado, Karan Dhingra, Clayton Collins, Sylvia Romero, Sam McGuire, John Heflin, and Hasan Wei

Civil Engineering

Faculty Advisors: Dr. Timothy D'Orazio and Dr. Cheng Chen

The design of our bridge was developed from the teams desire to create a bridge that would not only be aesthetically pleasing but would also be high in strength and comply with the guidelines that were set for the ASCE National Timber Bridge Competition. We ultimately chose the arch bridge for these reasons and for the challenge that it provided our team. The two arches on either side of our deck serve as the two main load bearing components. Based on the design the arch allows for the loads to be transferred along the curve and ultimately be distributed to the horizontal members that stretch from one end of the arch to the other. When determining the material for the arch we chose a glulam that would allow for flexibility in construction and that also comply with competition rules. Each arch is composed of seven pieced together layers of Douglas Fir #1 glulam’s that were each steamed for approximately two hours. The initial pieces of the glulam’s that created the base layer were laid over a plywood form and screwed down. The first layer was screwed down to the base layer from the underside using wood screws. The following pieces that created layers 2-7 were connected to the first layer using construction wood glue that expanded between the pieces and held each layer together. After the wood glue was added, each layer was reinforced by screws; this assisted in the strengthening the arch and further developing a greater stiffness and creating a smaller weight for the arch. The deck is composed of seven bolted together boxes that have horizontal and diagonal cross members that were connected with Simpson Strong Ties to assist with the support of the deck. On the top of each box we have 3 (2x6) and 1 (2x4). This totaled ~21.5 inches wide and ~62 inches in length. Below each deck section we have cold rolled steel members that sit on top of the 4x4’s that are connected to the vertical all-thread tension rods. The deck itself is free floating, meaning it is not attached to the 4x4’s that it sits on. However, the bolts at either end of the deck sit in pre-drilled holes in the 4x4s attaching both arches together. Our team decided to create a free moving deck. This deck would move slightly with the weight applied, and allowed for easy assembly and disassembly.

SOIL TEXTURE ANALYSIS FOR THE NEXT GENERATION ECOSYSTEM EXPERIMENT (NGEE)

By: Robin D. López

Civil Engineering

Faculty Advisors: Dr. Kwok-Siong Teh and Dr. Tim Kneafsey (Lawrence Berkeley National Laboratory)

To gain understanding of processes affecting possible releases of greenhouse gases and climatic feedback with thawing permafrost, research is being conducted in the Arctic region of northern Alaska for the Next Generation Ecosystem Experiment (NGEE). NGEE is a collaborative effort amongst several federal and state research institutions, as they collectively aim to assess and analyze a predictive model of the Arctic ecosystem in response to climate change. The Arctic is abundant with soil that has been frozen for thousands of years, otherwise known as permafrost. If global temperatures continue to rise, permafrost, which contains vast stores of organic material, is expected to thaw, which in turn could release the organic matter, leading to potential high release of greenhouse gases. Hence, this requires extensive field and laboratory investigations of permafrost cores to gain a better understanding of the links between soil properties, geomorphic features and micro-topography. Soil texture is both a qualitative and quantitative measurement performed in the field and laboratory, respectively. Differences in soil texture indicate a soils ability to retain moisture, organic material content, infiltration rate and other important characteristics of soil properties. Laboratory soil texture analysis has been performed on samples from permafrost cores to relate changes in subsurface soil texture to surface features, which ultimately will give a better understanding of surface and subsurface water movement that is vital in predicting permafrost thaw. The data compiled can help complete a part of the puzzle modelers will use to predict climate feedbacks in the Arctic region

Analysis of the CR Algorithm for the Reliability Assement of Real Time Hybrid Simuation

By: Maryam I. Khan

Civil Engineering

Faculty Advisor: Dr. Cheng Chen

Real Time Hybrid Simulation (RTHS) testing provides an analysis of the response for a given structure upon seismic loading. Within RTHS, a time delay is introduced via the servo hydraulic actuators of the physical component of the hybrid testing apparatus. We explore the error caused by the time delay in RTHS due to the nonlinearities from the servo hydraulic actuators. One way to reduce the error is by the implementation of a discrete transfer function, such as the CR Algorithm. We explore a multitude simulations run with 44 groundmotions.

USING SMART WEARABLE DEVICES FOR SEISMIC MEASUREMENTS AND POST-EARTHQUAKE RESCUE

USING SMART WEARABLE DEVICES FOR SEISMIC MEASUREMENTS AND POSTEARTHQUAKE / RESCUE / Zhaoshuo Jiang, Assistant Professor of Civil Engineering, San Francisco State University, CA, USA / Xiaorong Zhang, Assistant Professor of Computer Engineering, San Francisco State University, CA, USA / / Introduction / Human beings, us, live on the surface of the mother earth. The earth surface appears to be motionless, / unchanging and dependable to most people. However, in truth, according to plate tectonics theory [1] the / seemingly stable surface is made up of enormous pieces of rock plates that are slowly but constantly / moving. Those pieces continually collide with and rub against one another, and, at some point in time, / their edges abruptly crack or slip to release the unbearable stored energy, creating earthquakes. Although / small ones happen every day around the world without people even feeling about them, every so often, a / big earthquake occurs, which would lead to tragical destruction and loss of human lives. / California, as one example of the earthquake prone areas, has been stuck by several severe earthquakes in / recent history. For example, the Loma Prieta earthquake (magnitude 6.9) in 1989 caused an estimated $6 / billion in property damage and took away 63 human lives [2]. The Northridge earthquake (magnitude 6.7) / in 1994 brought an estimated $20 billion property damage and claimed the lives of 57 death with more / than 5,000 injured [3]. / Scientists can make reasonably long-term predictions, however, identifying the precise time frame and / location of quakes is much more complicated and no successful story has been heard yet. Before / researchers are able to find a way to predict earthquakes precisely in advance, and perhaps even control / them, it is critical to better prepare before they hit. / Currently, seismic stations are built around the world with high-fidelity sensors and equipment installed / to capture the earthquake records which later on will be used by seismologists to make quake predictions / and by building authorities as the basis for developing building codes that act as guidelines for designing / all the building structures. However, due to the high construction cost and operating expense, currently / there are limited numbers of seismic stations installed around the world and thus only limited numbers of / past earthquake ground motions are recorded. To have more probabilistically reliable results, there is an / essential need to use new emerging technologies for more comprehensive and accurate recording. / Ervasti et al [4] and Reilly et al [5] explored the idea of using Apple iPhones as sensors to record the / earthquake signals and showed very promising results. However, the scope and applicability of the study / are limited because it required the devices to be stationary before and during the extreme event. In / addition, it needed the mobile application (app) running on the background all the time, which would / drain the device’s battery and prevented its prevailing in actual practice. / / Proposed Solutions / With the advancement of wearable technologies and internet-of-things (LoT), more and more powerful / sensors are embedded into wearable devices, which touch every second of our daily life. These sensors / include kinematic sensors such as accelerometer, magnetometer, and gyroscope, environmental sensors / such as ambient light sensor, proximity sensor, temperature and humidity sensors, and physiological / sensors that can monitor the activities of heart, muscle, and brain. And most of these devices integrate / GPS and Internet connection, which allows for accurate indoor and outdoor localization of individual / devices as well as networking and communication among them. With the newly released wearable / devices equipped with advanced sensors, such as smart wristbands and smart watches, the abovementioned / concerns of the iPhones application can be resolved. / Firstly, the nature of wearing the wearable devices and the kinematic sensors in the wearable devices / provide means to better categorize behaviors of wearer (e.g. standing, walking, and running). Comparing / the measured acceleration data (one of typical measurements of earthquake ground motions) and the precategorized / baseline data of different behaviors, it is feasible to extract the earthquake ground motion / from the measurements without the need of immobilizing the devices. Secondly, by using sensors that are / able to capture the environmental measurements, the start of the extreme event can be determined. For / example, through the measurements of the heart rate sensors and the positioning systems, a threshold can / be set to start recording and transmitting important data (e.g. accelerations) to the cloud if the heart beats / of the wearers within 5 miles perimeter all hasten abnormally. This can avoid the need of running the app / 24/7 to wait for the extreme event, which can significantly reduce the battery consumption by recording / and transmitting data streams only when necessary. With those data available, we can then use signal / processing methods to filter out the noise and extract the real earthquake signals that can be used by / seismologists and building authorities. / After the earthquake strikes, it usually takes a great amount of efforts and time for the first responders to / locate the wounds and injures from the debris, which greatly reduces the survival chance of those people. / If one needs to locate the loved ones who might be inside the affected area, it might take days or even / weeks depending on the severity of the natural disaster. Besides the benefit of recording the earthquake / signals, the wearable devices can also play a very important role in post earthquake rescue. When an / extreme event is confirmed, a larger perimeter (potential damage zone) will be calculated according to the / acceleration measurements and all the sign-up wearable devices within that zone will be activated. / Together with the indoor and outdoor localization, the vital information of the wearer deciphered from the / physiological measurements will be send out to the cloud, which will be passed to the rescue teams to / develop their rescue plans (such as locating the injuries, setting the priority of rescue, and etc.). / Furthermore, using the combination of measurements from proximity sensor and ambient light sensor can / provide necessary information to determine if the wearers are under debris. If the likelihood is deemed to / be high, Bluetooth or Wi-Fi in the devices can be turned on as a hotspot to help the rescue team locate the / wearer, considering the possibility that the Internet connection might not be available after the disaster. / All these additional information could be extremely useful in assisting the rescue and dramatically / increase the change of survival. / What’s more, a user could choose to disclose her/his GPS and health status to the public or to specific / individuals only, so the authorized individuals/party could access that information online in real-time / immediately after the event. The age of waiting in front of the televisions or calling different agencies for / news about the loved ones will become a history. / This poster will describe the methodologies and some findings of the attempts of using smart wearable / devices as earthquake signal recorders and as cyber life straws during the post-earthquake rescue. / / Reference / [1] J.
