1. Subjective Cognitive Complaints in the Working Population : The Influence of Objective Cognitive Functioning and Working Conditions
Sammanfattning : Cognitive functioning is important for managing work and life in general. However, subjective cognitive complaints (SCC), involving self-perceived difficulties with concentration, memory, decision making, and clear thinking are common in the general and in the working population and can be coupled with both lowered well-being and work ability.

4. Exploring Cognitive Spare Capacity : Executive Processing of Degraded Speech

Cognitive resources are limited, and if listeners allocate a greater share of these resources to recovering the input signal in noise, fewer resources are available for interpreting and encoding its linguistic content.

5. Cognitive Sensing and Transmission Strategies
Sammanfattning : Many frequency bands for wireless services are severely underutilized by the primary users (PU) to which these bands are assigned. This motivates cognitive radios (CR), which identifies vacant spectrum and transmit accordingly. Many algorithms, some as simple as energy detection, are used to sense the spectrum. LÄS MER
