Today’s enterprise software systems are mission critical. Ideally they must run continuously, correctly. To do otherwise costs money. However, system failures will still occur. Continuous system monitoring can reduce the time to diagnosis, but comes at the cost of reduced system efficiency. One alternative, partial system monitoring, is to monitor at a minimal level to determine system health, ...

BACKGROUND AND PURPOSE Prolonged ambulatory ECG monitoring after cryptogenic stroke improves detection of covert atrial fibrillation, but its long-term cost-effectiveness is uncertain. METHODS We estimated the cost-effectiveness of noninvasive ECG monitoring in patients aged ≥55 years after a recent cryptogenic stroke and negative 24-hour ECG. A Markov model used observed rates of atrial fibr...

Although leveling is a very precise technique for geodetic deformation monitoring, it is quite expensive and timeconsuming. InSAR is a relatively new technique for precise deformation monitoring and has some important advantages compared to leveling: the high spatial resolution of the data and the relatively low costs of the technique. In this article both techniques are considered for the esti...

Monitoring the state of mechanical machine tool components is of growing importance for increasing machine tool availability and reducing inspection efforts and costs. Open Numeric Controls offer a new opportunity for getting access to signals of drives as well as of the control itself and to integrate end-user’s individual applications. Because the actual drive signals contain information on t...

Monitoring the performance of incident response (IR) management is important input for improving the IR management system. A set of performance indicators, which assists monitoring in a proper way, is described regarding: the incident response management system; information security culture; number of incidents responded to; average time spent on responding; consequences of incidents; number of...

Engineering structures such as bridges, tunnels, dams or towers are beginning to approach their service lifetime. To give an example, more than 20,000 bridges in Germany currently require immediate rehabilitation; similar situations apply in other countries. Thus, efficient and cost-effective structural health monitoring systems are needed to ensure serviceability and structural safety through ...

Behavior choice, coal mine monitoring, and control intensity are combined in a general mathematical model established from the perspective of a behavioral game. A case study is provided with effective conditions of monitoring provided. This paper defines the expected value difference of control return and behavior cost difference and discusses the measurement and optimization of variable indexe...

Monitoring manufacturing processes has been the focus of research in academia and industry for several decades due to expectation of high productivity, high product’s quality, and low costs. Sensors form one of the main components of a successful condition monitoring system. This paper presents a survey of the sensor technologies that have been implemented in research and industry. Advantages a...

OBJECTIVES To compare the costs and cost-effectiveness of managing patients with uncontrolled blood pressure (BP) using telemonitoring versus usual care from the perspective of the National Health Service (NHS). DESIGN Within trial post hoc economic evaluation of data from a pragmatic randomised controlled trial using an intention-to-treat approach. SETTING 20 socioeconomically diverse gene...

BACKGROUND To estimate the cost and cost-effectiveness of a project administering de-worming and weekly iron-folic acid supplementation to control anaemia in women of reproductive age in Yen Bai province, Vietnam. METHODS AND FINDINGS Cost effectiveness was evaluated using data on programmatic costs based on two surveys in 2006 and 2009 and impact on anaemia and iron status collected in 2006,...
