1

starting a device or service

The process of making a phone, card, or online account ready so you can use it.

نمط الاستخدام: the activation of [a device/service/account/card]
خطأ شائع:
Learners sometimes say *"open my account"* when they mean *"activate my account"*. "Open" is used when the bank first creates the account; "activate" is used when you make a card, phone, or service start working. Another mistake is using a verb form *"I will activation my card"*; the correct verb is *"activate"*.
المرادفات
enabling (A general word for making something able to work, not only for devices or services.)
الأضداد
deactivation (Refers to turning off or disabling a device, account, or service so it cannot be used.)

2

starting a plan or system

The act of making a plan, rule, or program start and really work.

نمط الاستخدام: the activation of [a plan/program/system/rule]
خطأ شائع:
Learners sometimes use *"start"* where a more formal context needs *"activation"*, for example *"the start of the emergency plan"* instead of *"the activation of the emergency plan"*. "Start" is fine in casual speech, but "activation" is preferred in official or written contexts for systems, rules, and protocols.
المرادفات
implementation (Focuses more on carrying out a plan over time, not just the moment when it is officially started.)
الأضداد
suspension (Refers to officially stopping or pausing a plan, rule, or system that was active.)
المتلازمات اللفظية
activation of the emergency plan |activation of sanctions |protocol activation |alarm activation |system activation |clause activation
الموضوعات

أمثلة
  • The activation of the emergency plan was ordered after the flood warnings were raised.
  • Automatic activation of the alarm occurs if the temperature rises above a set limit.
  • The contract includes an activation clause that triggers extra payments after a year.

making cells or molecules active

In science, the process when a cell, enzyme, or part of the brain becomes active and starts working.

نمط الاستخدام: the activation of [a cell/enzyme/receptor/brain region]
خطأ شائع:
Learners may confuse "activation" with "activity". "Activation" is the process of becoming active; "activity" is the ongoing action or level of work. For example, *"enzyme activation"* (the start of work) vs. *"enzyme activity"* (how strongly it works).
المرادفات
stimulation (Often refers to causing activity, but is less specific; "activation" usually describes the exact process of becoming active in a system.)
الأضداد
inhibition (Refers to preventing or reducing the activity of a cell, enzyme, or pathway, which is the functional opposite of activation.)
المتلازمات اللفظية
enzyme activation |immune cell activation |receptor activation |T-cell activation |brain activation |pathway activation
الموضوعات
science |medicine |health
أمثلة
  • The drug increases activation of specific receptors in the brain.
  • T-cell activation is a key step in the body’s immune response.
  • The scan showed strong activation in the visual cortex during the task.
  • Calcium ions play a crucial role in enzyme activation.

output of a neural network unit

In machine learning, the number that a neuron in a network sends out after a special function changes its input.

نمط الاستخدام: the activation of [a neuron/unit/layer]
خطأ شائع:
Learners sometimes mix up "activation" and "activation function". The activation function is the formula (like ReLU or sigmoid); the activation is the result after applying that formula.
المرادفات
output (A general word for what comes out of a system; "activation" is a specific kind of output in neural networks.)
الأضداد
suppression (Refers to forcing activations to be reduced or set to zero, effectively the opposite of producing a strong activation.)
المتلازمات اللفظية
neuron activation |activation function |hidden layer activations |ReLU activation |activation map |unit activation
الموضوعات
technology |science |computing
أمثلة
  • We visualized the activation of each layer to understand what the network was learning.
  • The neuron’s activation is clipped at zero by the ReLU function.
  • Batch normalization changes the distribution of activations during training.
  • Sparse activation helps the model focus on the most relevant features.
  • High activation in this filter suggests it is detecting vertical edges.
أمثلة للمتعلّمين
  • Each neuron in the network has an activation.
  • We save the activations from the last layer for analysis.
  • The activation becomes zero when the input is negative.
  • Different inputs produce different activation patterns.

putting troops into active service

In the military, the official act of making soldiers or units start active work or be ready to fight.

نمط الاستخدام: the activation of [troops/units/reserves]
خطأ شائع:
Learners may confuse "activation" with "training". Training is preparation; activation is the formal start of active service or readiness.
المرادفات
deployment (Deployment usually means sending forces to a location, while activation means placing them into active status or readiness.)
الأضداد
demobilization (Refers to taking troops out of active service, the opposite of activation in a military setting.)
المتلازمات اللفظية
activation order |activation of reserves |unit activation |brigade activation |activation ceremony
الموضوعات

أمثلة
  • The government authorized the activation of 5,000 reservists.
  • Activation of the unit was completed within 48 hours.
  • The activation order came late at night after the attack.
  • Following activation, the brigade moved to its designated positions.
  • The ceremony marked the activation of the new headquarters.

making material radioactive by irradiation

In nuclear science, the process when something becomes radioactive because it is hit by radiation.

نمط الاستخدام: the activation of [a material/sample/element]
خطأ شائع:
Learners may think "activation" here just means "turning something on" in a general sense, but in nuclear physics it has the specific meaning of making a material radioactive.
المرادفات
irradiation (Irradiation is the act of exposing something to radiation; activation refers specifically to the resulting change into a radioactive state.)
الأضداد
decay (Radioactive decay is the natural loss of radioactivity over time, which moves a material away from the activated state.)
