Calculating Stride Length & Stride Frequency

[ad_1]

The following exercise explains how you can calculate the stride length and stride frequency of a runner on a treadmill.

Consider first some definitions of terms:

Stride length: Stride Length corresponds to the horizontal distance between the location of a foot at one point in time (usually the first point of contact with the ground)to the same point of the same foot at the next occurrence of the selected position in the running cycle.

Step: A step corresponds to the horizontal distance between the location of a foot at one point in time (usually the first point of contact with the ground) to the same point of the contra-lateral foot at the next occurrence of the selected position in the running cycle. In essence two steps constitute a stride.

Stride Frequency: Stride frequency corresponds to the number of strides that are completed in a specified time period. The standard unit of measurement is the hertz (Hz) which records the number of cycles per second. Step frequency is the equivalent measure using a step (as defined above) as the core parameter.

Timecode: Time code records the passage of time via the use of a sequence of pairs of numbers separated by colons. e.g. 00:01:15:32. The first pair of numbers represents the number of hours, the second pair the number of minutes, the third pair the number of seconds and the last pair the number of hundredths of a second.

The speed of a runner can be defined as being equal to Stride Length × Stride Frequency

Given the relationship between running velocity, stride length and stride frequency plus a video record (with timecode) of a runner on a treadmill it is a straight forward matter to calculate values for the stride length and stride frequency of a runner at a known speed.

Ultrasonic Sensors – Distinct Devices and Different Uses

Ultrasonic sensors are devices that are utilized to detect the presence of foreign items. These can discreetly be put in courtyards and in houses to discover the presence of moving objects alien to the surroundings. They work at very high frequencies that are way beyond human hearing.

Ultrasonic detectors depend highly upon sound waves or radio sounds so as to translate the echoes and appraise specific attributes of their targets. They are frequently known as transceivers particularly when they function both in the receiving and sending of audio waves similar to the functions of the sonar or even the radar. They function as frequency waves of sounds that are created and assessed. The detector interprets the distance of an object by calculating the intervals at which signals are received.

Ultrasonic sensors have many other uses besides interpretation of distance. Among them is to get the measurement of wind direction or speed depending on the anemometer technology. Air and water speed, as well as tank fullness, can be measured as well. Multiple detectors are also used in the procedure. Ultrasonography, burglar alarms and humidifiers depend considerably upon those detectors also. Look at some of the devices found under this product category. Learn more about a few of it’s applications also.

Transducers and sensors.

Ultrasonic transducers are devices that are utilized to convert energy into sound waves. The most common examples are piezoelectric transducers. These use crystals which have the capacity to modify sizes especially when a particular quantity of voltage is used. It functions with the use of an alternating current thus creating the crystals oscillate during high frequencies. As these frequencies are generated, the sound waves increase.

Detectors are highly important instruments in the detection of ultrasound too. Systems may search for separate transmitters and recipients while some use both inside the piezoelectric transceiver. Other procedures that are thought in ultrasonic sensors are capacitive actuation and magnetostriction.

Application in medicine and other industries.

These sensors are popular in the medical field especially in the area of ultrasonography. Medical transducers have various sizes and shapes and are used to take images of various body components. The transducer is used in different ways: it might be inserted in the body or just used on the surface of the body.

In other areas, ultrasonic detectors work well with process plants and automated factories. On and off electronic outputs for detectors are used to discover object presence also. Some cleanup devices also use detectors. These gadgets function when the transducer is connected to a stainless steel bowl. Square waves can also be applied to exude energy on the liquid either in the form of isopropanol or water.

How Web Marketing and Ads Help Grow Business

Have you considered marketing your business online? SEO, content writing, social media campaigns, and online ads are some of the tactics that a business may need to deploy and gain in several different ways, helping promote product offerings.

Effectiveness

Internet marketing is more cost-effective than classic approaches like advertising on television or print media. For example, SEO is effective because it targets a specific audience that’s interested in the product on sale. This approach is critical to the prevention of marketing funds wastage.

Consider the fact that around 3.5 billion queries are run on Google each day. You may harness SEO and increase the search engine visibility of your web enterprise, increasing the chances of being found via Google if you offer the answers or solutions being sought. This is considered cost-effective because your online marketing efforts are being focused on people looking for something you have, rather than a general audience watching news or a favorite TV show.

Better Return on Investment

When the people you’re targeting via social media ads or SEO find your website and perform a desired action, such as buy, you’re registering a good return on investment. As more traffic and conversions are achieved, you get good value for your online marketing budget.

Reliable Performance Metrics

In case you’ve advertised via TV, newspapers, and billboards simultaneously before, you realize how tricky it is to link each such platform to its respective share of the buys, questions, orders, or registrations your business netted in a particular marketing campaign. That’d be tricky because most such results cannot always be traced back to the advertising platform.

Nonetheless, online marketing is better since it comes with accurate analytical instruments that marketers deploy to monitor the performance of every media involved. For instance, you may utilize such analysis to identify the traffic reaching your site from Google, Facebook, Twitter, or email campaigns. Additionally, you may refine your evaluations and discover the Google phrasing the highest converting searches used before reaching your company website. With the right answers, you can quickly identify the best/worst-performing components of your entire online marketing program so you can implement appropriate remedial measures.

Take advantage of online marketing and improve your SERP rankings, expanding your market-base.
