"It is that Al Qaeda is adapting its methods in ways that oftentimes make it difficult to detect".
Its acute angles and special coating make it difficult to detect on any enemy radar.
It's also more abundant than that from intact cells, but still rare enough to make it difficult to detect.
Even so, a stylist with a strong imprint can sometimes make it difficult to detect a designer's style at all, especially when the designer is a nascent talent.
While there is evidence that global warming should increase the frequency of very intense storms, their rarity and complexity make it difficult to detect climate change's fingerprint.
In exchange for more than $100,000, he had helped design a stealth exhaust system for China's cruise missiles to make it difficult to detect and destroy them.
The change sensed by the nanotube films is what enables the sensor to transmit what it is "feeling". Whether the sensor is being compressed or extended, the two nanofilms are brought closer together, which seems like it might make it difficult to detect which type of deformation is happening.
Consideration of production quantity needed along with control limit determination is important for the following competing two reasons: (1) Wider control limits make it difficult to detect the changes in the process, therefore producing excessive number of cars with paint defects.
These properties make it difficult to detect.
The number of transition types with varying duration can make it difficult to detect [28].
(i) An intrinsic reason: vendor-dependent implementation choices in some cases make it difficult to detect non-WiFi modulated signals or introduce latency in the receiving chain [10].
