Heart failure with preserved ejection fraction (HFpEF) is a form of heart failure in which the ejection fraction – the percentage of the volume of blood ejected from the left ventricle with each heartbeat divided by the volume of blood when the left ventricle is maximally filled – is normal, defined as greater than 50%; [1] this may be measured by echocardiography or cardiac catheterization.
Modalities applied to measurement of ejection fraction is an emerging field of medical mathematics and subsequent computational applications. The first common measurement method is echocardiography, [7] [8] although cardiac magnetic resonance imaging (MRI), [8] [9] cardiac computed tomography, [8] [9] ventriculography and nuclear medicine (gated SPECT and radionuclide angiography) [8] [10 ...
Performance improvement can be applied to either individual performance, such as an athlete, or organisational performance, such as a racing team or a commercial business. The United States Coast Guard has published the Performance Improvement Guide (PIG) , [ 1 ] which describes various processes and tools for performance management at the ...

Brooks discusses several causes of scheduling failures. The most enduring is his discussion of Brooks's law: Adding manpower to a late software project makes it later. Man-month is a hypothetical unit of work representing the work done by one person in one month; Brooks's law says that the possibility of measuring useful work in man-months is a myth, and is hence the centerpiece of the book.
At Toyota, it is usually a local improvement within a workstation or local area and involves a small group in improving their own work environment and productivity. This group is often guided through the kaizen process by a line supervisor; sometimes this is the line supervisor's key role.
At scheduled meetings, the FOMC meets and makes any changes it sees as necessary, notably to the federal funds rate and the discount rate. The committee may also take actions with a less firm target, such as an increasing liquidity by the sale of a set amount of Treasury bonds, or affecting the price of currencies both foreign and domestic by ...
A continual improvement process, also often called a continuous improvement process (abbreviated as CIP or CI), is an ongoing effort to improve products, services, or processes. [1] These efforts can seek " incremental " improvement over time or "breakthrough" improvement all at once. [ 2 ]
