Streaminghub - A Realtime Biosignal Processing Framework For Lab Scale Experimentation, Yasith Jayawardana

Computer Science Theses & Dissertations

In human subjects research, biosignals such as eye movements, heart rate, and brain activity, are often collected and analyzed to find patterns with tangible real-world implications. Modern advancements in technology have sparked interest towards analyzing biosignals in realtime. When developing such algorithms, one may expect to find free, open-source tools that provide easy access to live, recorded, and simulated data streams. Yet, biosignal interfaces are often vendor-specific, making cross-vendor biosignal streaming non-trivial. Likewise, reading biosignal datasets is also non-trivial, as their content may be arranged quite differently.

To combat this divide, we provide the scientific community with a realtime biosignal …

Geo-Slam: Using Geometric Hierarchies To Support Localization And Mapping In Forest Environments, Daniel Castellarin

Theses

Robust mapping and localization can be challenging in environments like forests where easily observable landmarks are virtually indistinguishable from each other. In such environments, GPS or robot odometry may also be compromised by the landscape, tree cover, or method of locomotion. Prior work discussed a method for creating geometric hierarchies to describe the relative positions of unlabeled landmarks. Notably, the polygons from these hierarchies were used to perform accurate place recognition from observations containing partial overlap and sensor noise. Here, we use geometric hierarchies to perform robust data association for collections of virtually identical 2D landmarks in direct support of …

Multi-Link Prediction For Mmwave Wireless Communication Systems Using Liquid Time-Constant Networks, Long Short- Term Memory, And Interpretation Using Symbolic Regression, Vishnu S. Pendyala, Milind Patil

Faculty Research, Scholarly, and Creative Activity

A significant challenge encountered in mmWave and sub-terahertz systems used in 5G and the upcoming 6G networks is the rapid fluctuation in signal quality across various beam directions. Extremely high-frequency waves are highly vulnerable to obstruction, making even slight adjustments in device orientation or the presence of blockers capable of causing substantial fluctuations in link quality along a designated path. This issue poses a major obstacle because numerous applications with low-latency requirements necessitate the precise forecasting of network quality from many directions and cells. The method proposed in this research demonstrates an avant-garde approach for assessing the quality of multi-directional …

Contextualizing Interpersonal Data Sharing In Smart Homes, Weijia He, Nathan Reitinger, Atheer Almogbil, Yi-Shyuan Chiang, Timothy J. Pierson, David Kotz

Dartmouth Scholarship

A key feature of smart home devices is monitoring the environment and recording data. These devices provide security via motion-detection video alerts, cost-savings via thermostat usage history, and peace of mind via functions like auto-locking doors or water leak detectors. At the same time, the sharing of this information in interpersonal relationships---though necessary---is currently accomplished on an all-or-nothing basis. This can easily lead to oversharing in a multi-user environment. Although prior work has studied people's perceptions of information sharing with vendors or ISPs, the sharing of household data among users who interact personally is less well understood. Interpersonal situations make …

A Framework For Evaluating The Security And Privacy Of Smart-Home Devices, And Its Application To Common Platforms, Ravindra Mangar, Timothy Pierson, David Kotz

Dartmouth Scholarship

In this article, we outline the challenges associated with the widespread adoption of smart devices in homes. These challenges are primarily driven by scale and device heterogeneity: a home may soon include dozens or hundreds of devices, across many device types, and may include multiple residents and other stakeholders. We develop a framework for reasoning about these challenges based on the deployment, operation, and decommissioning life cycle stages of smart devices within a smart home. We evaluate the challenges in each stage using the well-known CIA triad—Confidentiality, Integrity, and Availability. In addition, we highlight open research questions at each stage. …

Visible-Light-Driven Reactions From A Six-Coordinate Nickel(Ii) Complex, Lakmini Lochana Edirisinghe Arachchilage

Master's Theses (2009 -)

Transition metal complexes capable of absorbing visible light can be excited upon light irradiation and facilitate chemical bond formation and cleavage. In this approach, a transition metal-substrate complex is formed in the ground state, followed by photoinduced substrate activation via an inner-sphere mechanism. Unlike well-established photoredox catalysis that does not involve substrate binding, the ground-state interaction here is important for substrate activation. Among the 3d transition metals, nickel is considered a cost-effective alternative to Ru- and Ir-based photocatalysts due to its ability to accommodate different oxidation states. However, the application of Ni photocatalysis in synthesis had remained largely underexplored. In …

Water Body Satellite Images Segmentation Using Maxwell Boltzmann Distribution, Lama Affara, Ali El-Zaart, Rabih Damaj

BAU Journal - Science and Technology

Images can exhibit diverse attributes and characteristics, because of variations in both the quantity of each intensity level and their respective positions, histograms display varying distributions. Some images feature symmetric histograms, while others exhibit asymmetry. In image segmentation tasks, traditional mean-based thresholding methods work well with symmetric histograms, relying on Gaussian distribution definitions. However, situations arise where asymmetric distributions must be considered. Threshold-based segmentation entails the partitioning of intensity levels into separate regions determined by the threshold value. Within this category of thresholding methods, Minimum Cross Entropy Thresholding (MCET) stands out as a mean-based thresholding technique with a unique self-contained …

Pid Controller Design Of An Avr System, Soumya Pan

Manipal Journal of Science and Technology

Voltage control and reactive power management are two facets that enable the reliability of the transmission network. More reactive power demand causes a voltage drop at the generator terminal. Such reactive power demand may arise from some industries connected to the transmission line. Usually, this reactive power is of an inductive nature which causes the voltage drop. In this regard, automatic voltage regulation (AVR) is an important aspect that is responsible for the continuous adjustment of field excitation to maintain the generator terminal voltage constant. This is done by comparing the terminal voltage with a reference voltage and by changing …
