The treatment of weak signals is identified as a method to identify strategic surprises in a firm?s environment. Many researchers address the problem of anticipation of movements that have an impact on a firm?s environment. Weak signals are considered in...

There is wide agreement that a transition toward deeper forms of sustainability would require transformational changes at many levels, transcending current patterns of incremental progress. Transformational changes might only occur, in many instances, ov...

In submarine warfare systems, passive SONAR is commonly used to detect enemy targets while concealing one?s own submarine. The bearing information of a target obtained from passive SONAR can be accumulated over time and visually represented as a two-dime...

Most of the current research on the diagnosis of rolling bearing faults is based on vibration signals. However, the location and number of sensors are often limited in some special cases. Thus, a small number of non-contact microphone sensors are a subop...

Mariculture is crucial in environmental monitoring and safety assurance of marine environments. Certain mariculture areas are often partially or completely submerged in water, which causes the target signal to be extremely weak and difficult to detect. A...

Nonlinear amplification is typically done on velocity signals from low-strain pile integrity tests to enhance weak echoes and superimpose any peak reflections. This conventional method may sometimes fail to untangle the hidden information within the sign...

The periodic impulse characteristics caused by rolling bearing damage are weak in the incipient failure stage. Thus, these characteristics are always drowned out by background noise and other harmonic interference. A novel approach based on multi-resolut...
