Maddy wants to install a camera system but worries about how much storage space the recorded videos will use. Technology for motion detection can be useful here.
A change in an object's position in relation to its surroundings or a change in the environment in relation to an object is what is known as motion detection. It can be done using mechanical or electronic techniques. Motion perception is what happens when it happens in living things.
Optical and auditory signals are the two main ways that motion can be detected electrically. For optical detection, laser or infrared technologies may be employed. An infrared disturbance is picked up by a sensor in motion-detection devices like PIR motion detectors. A signal may then trigger an alarm and/or a camera to record a picture or a video of the incident.

what is another name for a child class? question 10 options: derived class sub class descendent class all of the above
A subclass is a class that is descended from another class (also a derived class, extended class, or child class). A superclass is the class from which a subclass is descended (also a base class or a parent class).
All classes, including the ones you create, share behavior that is specified and implemented by the Object class, which is found in the java.lang package. A hierarchy of classes is formed in the Java platform by the fact that many classes descend directly from Object, others derive from some of those classes, and so on.
The private members of a parent class are not inherited by a subclass. However, the subclass may also use the public or protected methods that the superclass provides to access its private fields.
A nested class gets access to all the properties and methods that are private to its parent class. As a result, a subclass inheriting a public or protected nested class gets indirect access to every private member of the superclass.

The security violation mode that should be configured for each access port is "restrict." This mode will cause the switch to drop frames with unknown source MAC addresses and send a notification to the syslog server when the maximum number of MAC addresses has been reached on the port.
In port security, the violation mode determines the action the switch takes when a security violation occurs on the port. There are several possible violation modes:
Protect: This mode allows the port to continue to forward traffic, but it will send an alert to the syslog server to notify the administrator of the violation.Shutdown: This mode disables the port immediately when a violation occurs.

what is the correct selector for targeting all text inputs that are not disabled?what is the correct selector for targeting all text inputs that are not disabled?
The input type="text"]:options:not ([disabled]). In CSS, focusable elements that are not disabled and are consequently enabled are chosen.
First, reverse the sequence of the HTML components such that the label comes after the input. As a result, the styling rules will function as intended. Then comes the fun part: place text input labels on the left side using CSS! input[type=radio]: disabled+label functions as a shahr. An input text field is targeted using a CSS attribute selector. Use input[type=text] to target input text fields with the 'text' type. By adding the e-disabled property to the input parent element and setting the disabled attribute to the input element, you can disable the TextBox.

The rotational delay and transfer time are partially determined by rotational speed, expressed in revolutions per minute (RPM). Typically, manufacturers report seek times of 8 to 10 ms.
Hard drives are often restricted to a transfer rate of between 100 MBps and 200 MBps because of how they operate—with rotating discs—and how they store and access data. Data is transferred from the disk over a period of time, or "transfer time." The speed of the disk's spinning affects it. The number of bytes on a single track is also referred to as the disk density, and the more quickly a disk rotates, the faster we can read data from it.

if 8 mhz clock is used as the system clock and the systick selects it as the clock, what should the systick load register be in order to generate a systick interrupt every microsecond?
To generate a systick interrupt every microsecond with an 8 MHz clock, the systick load register should be set to 7999. A systick interrupt is a type of interrupt that is generated by the systick timer, which is a timer that is built into many microcontroller systems.
The systick timer is typically used to generate periodic interrupts, which can be used to trigger events or tasks at regular intervals. The frequency at which the systick interrupt is generated is determined by the value that is loaded into the systick load register, and the systick interrupt can be used for a variety of purposes, such as maintaining a real-time clock, implementing timeouts, or managing the scheduling of tasks.
In order to generate a systick interrupt every microsecond with an 8 MHz clock, the systick load register would need to be set to 7999. This is because the systick timer counts down from the value that is loaded into the systick load register, and 8 MHz is equal to 8,000,000 cycles per second.
Therefore, to generate a systick interrupt every microsecond, the systick load register would need to be set to 8,000,000 / 1,000 = 7999.

which technique did we discuss in class that has been used to attempt to regrow damaged axons in the cns?
For people who have had a spinal cord injury or stroke, persistent deficits result from the adult CNS axons' inability to regenerate.
The inability of damaged axons to repair and recreate functional connections with their original targets leads to permanent impairments after CNS injury. In contrast, peripheral nerve damage is followed by a powerful regeneration process, which may result in the restoration of sensory and motor abilities. This healing response necessitates the extensive activation of epigenetic and transcriptional alterations in damaged neurons. Understanding how peripheral axon damage causes these pervasive changes through the coordinated actions of transcription factors, epigenetic modifiers, and, to a lesser extent, microRNAs, has advanced significantly in recent years. These new findings provide light on the critical function of coordinated gene expression and chromatin remodelling in the neuronal response to damage, even if many concerns remain about the interaction between these systems.
