Nature Inspired Scenes for Guided Mindfulness Training: Presence, Perceived Restorativeness and Meditation Depth

2019

Practicing mindfulness-based stress reeducation and other contemplative practices generates a number of health and human performance benefits. However, limited access to qualified training and practice support, as well as poor practice environments, makes it difficult to sustain the habits necessary to develop the attentional regulation skills needed to benefit from mindfulness. In this paper, we report on our research, which focuses on developing immersive environments to support mindfulness-based stress reduction practices. We specifically look at how the design of a virtual environment can foster a restorative experience, if that restorative experience is associated with the depth of the…

OnMLM: An Online Formulation for the Minimal Learning Machine

2019

Minimal Learning Machine (MLM) is a nonlinear learning algorithm designed to work on both classification and regression tasks. In its original formulation, MLM builds a linear mapping between distance matrices in the input and output spaces using the Ordinary Least Squares (OLS) algorithm. Although the OLS algorithm is a very efficient choice, when it comes to applications in big data and streams of data, online learning is more scalable and thus applicable. In that regard, our objective of this work is to propose an online version of the MLM. The Online Minimal Learning Machine (OnMLM), a new MLM-based formulation capable of online and incremental learning. The achievements of OnMLM in our…

Mitochondrial DNA in the central european population

2000

Sequencing of mtDNA is an advanced method for the individualisation of traces. Disadvantages of this method are expensive and time-consuming analysis and evaluation procedures as well as the necessary stock of population-genetic data which is still insufficient. Central European institutes of forensic medicine from Germany, Austria, and Switzerland have been working together since the beginning of 1998 to establish a mtDNA database. The aim is to build up a large stock of forensically established data and provide population-genetic data for frequency investigations, which will serve as a basis for expert opinions and scientific research. Good data quality is ensured by using original sequen…

Car sequencing versus mixed-model sequencing: A computational study

2014

Abstract The paper deals with the two most important mathematical models for sequencing products on a mixed-model assembly line in order to minimize work overload the mixed-model sequencing (MMS) model and the car sequencing (CS) model. Although both models follow the same underlying objective, only MMS directly addresses the work overload in its objective function. CS instead applies a surrogate objective using so-called sequencing rules which restrict labor-intensive options accompanied with the products in the sequence. The CS model minimizes the number of violations of the respective sequencing rules, which is widely assumed to lead to minimum work overload. This paper experimentally co…

Placing links in mobile banking application

2005

This study compares two alternative ways to organize links as navigation elements in mobile banking applications. For the comparison, two alternative banking applications were tested. The applications that were tested had the same content but different ways to navigate with links. One of them provided a system where the user was required to use specific menu pages for navigation and where there were no cross-navigation enabling links on content pages. The other application had cross-navigation enabling links on content pages. The comparison was done by conducting a usability test with 30 test users. The users' performance and subjective feedback were measured in the test. The application wi…

Improving the performance of CAR systems based on mobile phones

2013

Collaborative Augmented Reality (CAR) systems allow multiple users to share a real work environment including computer-generated images in real time. Currently, the hardware features of most mobile phones makes them a natural platform for CAR systems. However, the wide variety of these hardware features can have important effects on the performance of the mobile CAR applications. This thesis proposes a performance characterization and improvement of CAR systems based on mobile phones. The research results, at the time of writing this paper, shows that a CAR system using mobile phones as clients and with a single server can support up to one thousand clients while providing interactive respo…

Mobile Search - Social Network Search Using Mobile Devices Demonstration

2008

Mobile search prototype demonstrates the possibilities of social network search in N800 mobile devices. Search is initiated from a N800 mobile device to search the contacts in mobile device's addressbook. The contacts can be other N800 mobile devices running mobile Web server or normal Web servers in the Internet with Drupal content management system. Mobile device users can select which of their personal information such as phone numbers, calendar data etc. to share via a mobile Web server. The proposed search mechanism has many benefits compared to centralized Web search engines like Google. The search can locate information which is not referenced anywhere and thus allows hidden or rare …

Improved support for streaming services in vehicular networks

2004

This paper presents a resource management mechanism aimed at improving the effectiveness of streaming services in vehicular networks. The scenario considered in this paper is that of a group of customers located into a same public vehicle, e.g. a moving train connected to the network via a satellite link, and requesting either video-on-demand-like services, as well as real-time diffusive (broadcast) streaming services. We show that a proxy server, devised to introduce an elastic buffer aimed at decoupling the information retrieval download speed on the outer network from the natural play-out speed used in the vehicular network, results to be an extremely effective approach in reducing the o…

Geometric Calculus Applications to Medical Imaging: Status and Perspectives

2021

Medical imaging data coming from different acquisition modalities requires automatic tools to extract useful information and support clinicians in the formulation of accurate diagnoses. Geometric Calculus (GC) offers a powerful mathematical and computational model for the development of effective medical imaging algorithms. The practical use of GC-based methods in medical imaging requires fast and efficient implementations to meet real-time processing constraints as well as accuracy and robustness requirements. The purpose of this article is to present the state of the art of the GC-based techniques for medical image analysis and processing. The use of GC-based paradigms in Radiomics and De…
