Demonstrating TapType for mobile ten-finger text entry anywhere
(2022)Conference on Human Factors in Computing Systems - ProceedingsWe demonstrate a mobile text entry system that brings full-size ten-finger typing to everyday surfaces, allowing users to type anywhere. Our wearable wristband TapType integrates accelerometers that sense vibrations arising from finger taps against a passive surface, from which our Bayesian neural network estimates a probability distribution over the fingers of the hand. Given a pre-defined key-finger mapping, our text entry decoder fuses ...Conference Paper -

AutoGrad: Automated Grading Sofware for Mobile Game Assignments in SuaCode Courses
(2021)Proceedings of the 10th Computer Science Education Research Conference (CSERC '21)Automatic grading systems have been in existence since the turn of the half-century. Several systems have been developed in the literature with either static analysis and dynamic analysis or a hybrid of both methodologies for computer science courses. This paper presents AutoGrad, a novel portable cross-platform automatic grading system for graphical Processing programs developed on Android smartphones during an online course. AutoGrad ...Conference Paper -
SuaCode Africa: Teaching Coding Online to Africans using Smartphones
(2021)Proceedings of the 10th Computer Science Education Research Conference (CSERC '21)There is a burgeoning trend of smartphone ownership in Africa due to the low costs of Android smartphones and the global increase in social media usage. Building upon our previous work that introduced a smartphone-based coding course to secondary and tertiary students in Ghana via an in-person program and an online course, this work introduced Africans in 37 countries to our online smartphone-based course in 2019. Students in this 8-week ...Conference Paper -
Optimal ITAE Criterion PID Parameters for PTn Plants Found with a Machine Learning Approach
(2021)Various approaches are known from the literature on how to find optimal parameter sets for PID control from step responses of plants. The methods of Ziegler- Nichols [1] or Chien, Rhones and Reswick [2] are best known. These are heuristic processes which, although they result in stable control systems, have to be further optimized in practice. One of the optimization methods is carried out using the ITAE criterion (integral of time-multiplied ...Conference Paper -

High-Conductance, Ohmic-like HfZrO4 Ferroelectric Memristor
(2021)ESSDERC 2021 - IEEE 51st European Solid-State Device Research Conference (ESSDERC)The persistent and switchable polarization of ferroelectric materials based on HfO2-based ferroelectric compounds, compatible with large-scale integration, are attractive synaptic elements for neuromorphic computing. To achieve a record current density of 0.01 A/cm(2) (at a read voltage of 80 mV) as well as ideal memristive behavior (linear current-voltage relation and analog resistive switching), devices based on an ultra-thin (2.7 nm ...Conference Paper -
2QoSM: A Q-Learner QoS Manager for Application-Guided Power-Aware Systems
(2021)2021 IEEE 14th International Symposium on Embedded Multicore/Many-core Systems-on-Chip (MCSoC)This paper describes the design and performance of Q-learning-based quality-of-service manager (2QoSM) for compute-aware applications (CAAs) as part of platform-agnostic resource management framework. CAAs and hardware are able to share metrics of performance with the 2QoSM and the 2QoSM can attempt to reconfigure CAAs and hardware to meet performance targets. This enables many co-design benefits while allowing for policy and platform ...Conference Paper -
Preliminary design of actuators for waling robot on the Moon
(2022)Legged robots have been proposed as a possible alternative to wheeled systems for accessing so-far hard to reach locations in our solar system. However, despite promising results in this field, significant challenges have to be solved before deployment. In particular, the actuation of walking robots in space is still an open engineering question. In this work, we focus on actuation of space-legged robots and propose a preliminary actuator ...Conference Paper -
HeadPosr: End-to-end Trainable Head Pose Estimation using Transformer Encoders
(2021)2021 16th IEEE International Conference on Automatic Face and Gesture Recognition (FG 2021)Head pose estimation (HPE) is the task of estimating head pose given an RGB image, video, or RGB-D data. In this paper, a network, HeadPosr is proposed to predict the head poses using a single RGB image. HeadPosr uses a novel architecture which includes a transformer encoder. In concrete, it consists of: (1) backbone; (2) connector; (3) transformer encoder; (4) prediction head. The significance of using a transformer encoder for HPE is ...Conference Paper -
Transferable Models to Understand the Impact of Lockdown Measures on Local Air Quality
(2021)2021 17th International Conference on Distributed Computing in Sensor Systems (DCOSS)The COVID-19 related lockdown measures offer a unique opportunity to understand how changes in economic activity and traffic affect ambient air quality, and how much pollution reduction can the society offer through digitalization and mobility-limiting policies. In this work, we estimate pollution reduction over the lockdown period by using the measurements from ground air pollution monitoring networks, training long-term prediction models ...Conference Paper -
Improving the Generalization Capability of DNNs for Ultra-low Power Autonomous Nano-UAVs
(2021)2021 17th International Conference on Distributed Computing in Sensor Systems (DCOSS)Deep neural networks (DNNs) are becoming the first-class solution for autonomous unmanned aerial vehicles (UAVs) applications, especially for tiny, resource-constrained, nano-UAVs, with a few tens of grams in weight and subten centimeters in diameter. DNN visual pipelines have been proven capable of delivering high intelligence aboard nano-UAVs, efficiently exploiting novel multi-core microcontroller units. However, one severe limitation ...Conference Paper -
Towards On-demand Gas Sensing
(2021)2021 17th International Conference on Distributed Computing in Sensor Systems (DCOSS)Low-power operation of power-hungry MOX sensors is usually achieved by duty cycling them periodically. However, a difficulty arises if a sensor is operated at irregular time intervals due to intermittent energy availability in energy-neutral or batteryless applications. In this work, we propose a compensation method which re-maps on-demand measurements to virtually duty-cycled readings in the value domain by taking the duration of the ...Conference Paper -
Steady state lasing in strained germanium microbridges as fundamental measure for the crossover to direct band gap
(2021)2021 IEEE 17th International Conference on Group IV Photonics (GFP)The realization of a laser on silicon (Si) from group IV materials is a long-cherished wish of the semiconductor industry; it would enable the mass production of photonic systems at low cost. However, the path towards an efficient light emitter requires material with a direct band gap, in line with all the typical group III-V lasers platforms [1]-[4]. Such configuration can be achieved by loading Ge with tensile strain [5] by alloying ...Other Conference Item
