Machines

579
Machines are complex structures consisting of movable, pin-connected multi-force members that work together to transmit forces. One example of a machine is the cutting plier, which is used to cut wires by applying forces to its handles. When equal and opposite forces are exerted on the handles of the cutting plier, they cause the cutting edges to come together and apply equal and opposite reaction forces on the wire, which are greater than the applied forces.

Machines are complex structures consisting of movable, pin-connected multi-force members that work together to transmit forces. Consider a lifting tong carrying a 100 kg load. It comprises movable sections DAF and CBG linked together with member AB.

A toggle clamp is a mechanical device commonly used for holding and clamping objects in various applications, such as woodworking, metalworking, and assembly operations. Consider a toggle clamp subjected to a force of 200 N at the handle. The vertical clamping force can be calculated, provided the dimensions of the toggle clamp are known.
The toggle clamp system is a machine structure consisting of movable, pin-connected multi-force members that form a stabilized system to transmit forces. The...

Avoidance Learning and Learned Helplessness

2.6K
Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli.
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...

Associative Learning01:27

Associative Learning

1.3K
Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.
Classical conditioning, also known...

Purposive Learning

E. C. Tolman emphasized the purposiveness of behavior — the idea that much of our behavior is goal-directed. For instance, employees who aim for a promotion work diligently to meet their targets. Tolman argued that when classical conditioning and operant conditioning occur, the organism acquires certain expectations. In classical conditioning, a child might fear a dog because they expect it to bite. In operant conditioning, a person might consistently work overtime because they expect a...

Area of Science:

  • Audiology
  • Machine Learning
  • Cloud Computing

Background:

  • Recent advancements in cloud computing, real-time web audio, and machine learning have enabled sophisticated audiometric assessments.
  • Online platforms can now offer advanced hearing tests without custom programming or specialized hardware.

Purpose of the Study:

  • To evaluate the accuracy and reliability of a novel online machine learning audiogram estimation method.
  • To compare this new method against an online implementation of the modified Hughson-Westlake technique.

Main Methods:

  • Air conduction pure-tone audiometry was conducted on 21 participants (ages 19-79) with diverse hearing abilities.
  • Two repetitions of online machine learning and modified Hughson-Westlake audiogram estimations were performed per ear.
  • Threshold estimates were compared at standard audiogram frequencies (0.25-8 kHz).

Main Results:

  • Both methods yielded highly similar threshold estimates (mean absolute difference: 3.24 ± 5.15 dB).
  • The machine learning method required fewer samples to estimate thresholds and provided continuous spread estimates.
  • Repeatability was good for both methods (ML: 2.85 ± 6.57 dB; Hughson-Westlake: 1.88 ± 3.56 dB).

Conclusions:

  • Online machine learning audiometry offers comparable accuracy and reliability to conventional methods in a shorter time.
  • This method provides additional audiogram details beyond traditional threshold estimation.
  • The platform's potential for expansion to other audiological tests could unify hearing assessments into a single, efficient procedure.
