What is RFID technology and how does it work? RFID is a method of data collection that involves automatically identifying objects through low-power radio waves. Data is sent and received with a system consisting of RFID tags, an antenna, an RFID reader, and a transceiver. What are the advantages of RFID? Advantages of RFID RFID […]
What materials are used for building houses?
What materials are used for building houses? Wood, cement, aggregates, metals, bricks, concrete, clay are the most common type of building material used in construction. The choice of these are based on their cost effectiveness for building projects. What are the 3 types of construction? Broadly, there are three sectors of construction: buildings, infrastructure and […]

Why do we use different temperature scales?
Why do we use different temperature scales? They are used because of preference or convenience, not necessity. These scales came about historically when there were no standards to calibrate a thermometer against. The Fahrenheit scale used the temperature of the coldest thing then known for its zero, which was salty ice. When was the temperature […]
What are the defects that can be identified by NDT techniques?
What are the defects that can be identified by NDT techniques? This method allows for the detection of corrosion, misalignment, damage, cracks, and more. Visual testing is inherent in most other types of NDT as they will generally require an operator to look for defects. What is defect in NDT? Generally a defect can be […]
What is the order through which blood flows in vessels from the heart back to the heart?
What is the order through which blood flows in vessels from the heart back to the heart? Blood Vessels: Circulating the Blood Through the thin walls of the capillaries, oxygen and nutrients pass from blood into tissues, and waste products pass from tissues into blood. From the capillaries, blood passes into venules, then into veins […]
How do you implement counting semaphores?
How do you implement counting semaphores? Counting Semaphore struct Semaphore. { int value; // processes that can enter in the critical section simultaneously. queue type L; // L contains set of processes which get blocked. } Down (Semaphore S) { SS.value = S.value – 1; //semaphore’s value will get decreased when a new.

In what situation should a pedestrian give a car right of way?
In what situation should a pedestrian give a car right of way? When a pedestrian is crossing a roadway at any point other than within a marked crosswalk or within an unmarked crosswalk at an intersection, he or she must yield the right of way to all vehicles. In other words, a pedestrian does not […]
Can superposition theorem be applied to a circuit containing one AC and one DC source?
Can superposition theorem be applied to a circuit containing one AC and one DC source? Another limitation of these methods is that the sources must all be of the same current type: ac or dc. The superposition theorem does not have this limitation, which makes it a valuable technique in electronic circuit design. The superposition […]
