Using deep neural networks for kinematic analysis: Challenges and opportunities

2020

Kinematic analysis is often performed in a lab using optical cameras combined with reflective markers.\ud With the advent of artificial intelligence techniques such as deep neural networks, it is now possible\ud to perform such analyses without markers, making outdoor applications feasible. In this paper I summarise\ud 2D markerless approaches for estimating joint angles, highlighting their strengths and limitations.\ud In computer science, so-called ‘‘pose estimation” algorithms have existed for many years. These methods\ud involve training a neural network to detect features (e.g. anatomical landmarks) using a process called\ud supervised learning, which requires ‘‘training” images to be …

Decoding Individual differences and musical preference via music-induced movement.

2022

AbstractMovement is a universal response to music, with dance often taking place in social settings. Although previous work has suggested that socially relevant information, such as personality and gender, are encoded in dance movement, the generalizability of previous work is limited. The current study aims to decode dancers’ gender, personality traits, and music preference from music-induced movements. We propose a method that predicts such individual difference from free dance movements, and demonstrate the robustness of the proposed method by using two data sets collected using different musical stimuli. In addition, we introduce a novel measure to explore the relative importance of dif…

Forecasting future trajectories for immersive journalism

2021

In this book we have critically explored the emerging practices of immersive journalism. In the news business, experimenting with new forms of storytelling has become the new normal. After spending a decade to get familiar with simple virtual reality tools, however, the future of immersive journalism is still considered uncertain. Immersive storytelling appears to become more concentrated on special events and locations. Journalistic virtual reality skills are increasingly crafted away from the newsrooms by small and specialized subcontractors. Sponsoring VR by the big tech companies tends to diminish in parallel with a growing move towards augmented reality investments. peerReviewed

The influence of rhythmic and spectro-timbral musical features on gait-related movement

2017

Music makes us move, and humans have the universal tendency to synchronise their movements to music. This phenomenon has been used in music therapy to help people with movement disorders regain control over their movements. Rhythmic auditory stimulation has shown promising results in gait rehabilitation in various clinical populations. In healthy populations, various differences have been found between movement while walking to musical and metronome stimuli in terms of stride length. However, insufficient research has been conducted concerning the musical features that could evoke this difference, and which gait-related movements might change under the influence of music. The aim of this mo…

How to Sell SaaS: A Model for Main Factors of Marketing and Selling Software-as-a-Service

2011

Software-as-a-Service providers have been growing fast while the contemporary research literature has neglected analysis of their business-critical marketing and sales processes. In this paper we collect the key factors characterizing how to market and sell SaaS to business customers into an eight dimensional model. We also use an explorative multi-case study to observe six SaaS providers and validate the model. The interviewed providers emphasized use of the Internet for marketing communication while personal direct sale was the dominating sales approach. Customer acquisition cost was the key performance indicator for marketing and sales while customer lifetime value and churn were the KPI…

Proton Direct Ionization Upsets at Tens of MeV

2023

Experimental monoenergetic proton single-event upset (SEU) cross sections of a 65-nm low core-voltage static random access memory (SRAM) were found to be exceptionally high not only at low energies ($ 3 MeV and extending up to tens of MeV. The SEU cross Section from 20-MeV protons exceeds the 200-MeV proton SEU cross Section by almost a factor of 3. Similarly, monoenergetic neutron cross sections at 14 MeV are about a factor of 3 lower than the 20-MeV proton cross section. Because of Monte Carlo (MC) simulations, it was determined that this strong enhancement is due to the proton direct ionization process as opposed to the elastic and inelastic scattering processes that dominate the SEU res…

Performance evaluation of OpenFlow enabled Commodity and Raspberry-pi Wireless Routers

2017

Software defined network (SDN) allows the decoupling of data and control plane for dynamic and scalable network management. SDN is usually associated with OpenFlow protocol which is a standard interface that enables the network controllers to determine the path of network packets across a network of switches. In this paper, we evaluate openflow performance using commodity wireless router and raspberry pi with two different SDN controllers. Our test setup consists of wired and wireless client devices connected to openflow enabled commodity wireless router and raspberry pi. All clients used traffic generator tool to transmits data to a sink server host. The results are promising and paves the…

Vehicles, replicators, and intercellular movement of genetic information: evolutionary dissection of a bacterial cell.

2012

Prokaryotic biosphere is vastly diverse in many respects. Any given bacterial cell may harbor in different combinations viruses, plasmids, transposons, and other genetic elements along with their chromosome(s). These agents interact in complex environments in various ways causing multitude of phenotypic effects on their hosting cells. In this discussion I perform a dissection for a bacterial cell in order to simplify the diversity into components that may help approach the ocean of details in evolving microbial worlds. The cell itself is separated from all the genetic replicators that use the cell vehicle for preservation and propagation. I introduce a classification that groups different r…
