Factors influencing performance

Questions have been raised about the feasibility of establishing evaluation norms that can be used across different populations and settings, or with similar tests used on different computer test systems. Certainly, situational factors influence performance on computerized performance tests. In addition, epidemiological factors, such as gender and age, have been demonstrated to influence performance on these tests. Due to mechanical and electronic differences across computer systems,... 

There are materials with low or no permeability to different environments or products. Different factors influence performance such as being pinhole-free chemical composition, crosslinking, modification, molecular orientation density, and thickness. The coinjection and...

The following discussion will first address models of dynamic and naturalistic decision making. These models both illustrate naturalistic decision-making strategies and explain their relation to experience and task familiarity. A brief discussion wftl also be provided on teams and team leadership, in naturalistic settings. Attention wdl then shift to the issue of time pressure and stress and how this factor influences performance in naturalistic decision making. 

The engineering properties of soils used for embankments, such as their shear strength and compressibility, are influenced by the amount of compaction they have undergone. Accordingly, the desired amount of compaction is established in relation to the engineering properties required for the embankment to perform its design function. A specification for compaction needs to indicate the type of compaction equipment to be used, its mass, speed and travel, and any other factors influencing performance such as frequency of vibration, thickness of layers to be compacted and number of passes of the compactor (Table 9.8). 

It is important to note that the factors influencing performance may vary over time as material ages or environmental conditions change. 

Chemical, thermodynamic, and physical principles underpin the corrosion mechanisms and their rates, which occur in any given service test. Each investigator must address the relevant principles operating in the test environment to fully understand the factors influencing performance. 

There are materials with low or no permeability to different environments or products. Barrier plastics are used with their technology not becoming more complex but more precise. Different factors influence performance such as being pinhole-fi ee chemical composition, crosslinking, modification, molecular orientation density, and thickness. The coextrusion and coinjection processes are used to reduce permeability while retaining other desirable properties. Total protection against vapor transmission by a single barrier material increases linearly...
