AIMS Optimizing cardiac resynchronization therapy (CRT) devices has become more complex since modification of both atrioventricular (AV) and interventricular (VV) stimulation intervals has become possible. The current paper presents data from the routine use of impedance cardiography (IC)-based cardiac output (CO) measurements to guide the optimization of AV- and VV-interval timing of CRT devic...

INTRODUCTION Before the advent of software engineering, the lack of memory space in computers and the absence of established programming methodologies led early programmers to use self-modification as a regular coding strategy. Although unavoidable and valuable for that class of software, solutions using self-modification proved inadequate while programs grew in size and complexity, and securit...

In this paper, we discuss the research topic of precise interaction for Wearable Augmented Reality (AR). Our research focus is towards improving interaction with wearable AR systems to assist in the creation and modification of user contents. We present a set of techniques that supports both the creation and modification of virtual models for outdoor wearable AR. Based on our experience, we dis...

With digital recording devices readily available to most people, events are documented and shared on-line in real time by the “person on the street.” The ease of creation and dissemination belies what archivists know will be the long-term challenges of organizing and preserving collections of born-digital information. While other processes require little modification, the inherent fragility of ...

The growing concern about wide area power system disturbances and their impact on power systems have reinforced interest in the new generation of system protection tools. Their application depends on their reliability, which, in turn, depends on the reliability of the hardware infrastructure on which they rely. In this paper, we propose a modification of a Voltage Instability predictor (VIP) [1...

This paper presents an investigation into total ionizing dose (TID) effects on I-V and noise characteristics of MOS transistors manufactured in a 0.18 μm CMOS Image Sensor (CIS) process. The CIS are intended for use in space science missions experiencing harsh radiation environments, such as ESA’s forthcoming JUICE mission. Devices were therefore irradiated to various TID levels up to 1 Mrad. F...

This paper reviews current approaches to the enhancement of bone regeneration at the interface with implant devices, by immobilization of biomolecules to titanium surfaces. In particular, techniques based on surface linking of peptides or extracellular matrix (ECM) proteins are reviewed, trying to describe surface modification approaches and to present results of chemico-physical and biological...

Background: The use of stapling devices for performing gastrointestinal anastomosis has gained wide acceptance in the last decade. Linear cutting devices have been used routinely during gastrointestinal operations in our hospital since 1992. However, we still have shortage of stapling devices due to cost reduction politics. Methods: We propose a modification of the standard technique in order t...

In the past decade among the main developments in the field of bionanotechnology is the application of proteins in devices. Research focuses on the modification of enzyme systems by means of chemical and physical tools in order to achieve full control of their function and to employ them for specific tasks. Membrane protein channels are intriguing biological devices as they allow the recognitio...
