The phrase "abnormal speeds" is correct and usable in written English.
It can be used to describe speeds that are unusual or not typical, often in contexts related to vehicles, machinery, or data transfer rates.
Example: "The vehicle was detected traveling at abnormal speeds, raising concerns about safety on the highway."
Alternatives: "unusual speeds" or "irregular speeds".
The movement was frequently violent -- sometimes terrifyingly so -- and abnormal speed alternated with abnormal stillness.
The pattern was one familiar to most hour-long documentaries that could feasibly fit into 25 minutes – the series trailer showing the presenter on a mountain, the shot of clouds travelling at abnormal speed, expert waffle, guidebook waffle, waffle from people in the street, sunsets, generic tinkling piano, images capturing the presenter in physical discomfort or a humorous scrape, etc.
ADDIS ABABA, Ethiopia — The captain of a doomed Ethiopian Airlines jetliner faced an emergency almost immediately after takeoff from Addis Ababa, requesting permission in a panicky voice to return after three minutes as the aircraft accelerated to abnormal speed, a person who reviewed air traffic communications said Thursday.
The technical dimension also includes the installation criteria (d) for the detection devices (abnormal driving speed level, black spot...)...
As the tension builds to its climax, the film manifests what the critic Arthur Vesselo called Hitchcock's mastery of contrast, "balancing the normal against the abnormal, slowness against speed, sound against silence, humour against terror".
The four families of biomechanical hypotheses are 1) abnormal TSPs, such as speed of walking and stride length; 2) restricted kinematics (movement patterns); 3) altered kinetics, (altered forces) and 4) elevated plantar pressures on the ulcerated and non-ulcerated foot [ 9].
Fig. 4a, b shows both modes of β x speeds (normal and abnormal).
His speed is altogether abnormal.
"The fact that several events are speeded up is abnormal," says Reinisch.
Abnormal movement decreased after gait velocity improvement [ 49] and gait speed is a reliable outcome measure for short-term intervention in stroke patients.
(4) The AECD applies only for engines that will be installed in emergency vehicles, and the need is justified in terms of preventing the engine from losing speed, torque, or power due abnormal conditions of the emission control system, or in terms of preventing such abnormal conditions from occurring, during operation related to emergency response.
