Consumer will keep expecting more and more advanced features and functions in apps. Often time, mobile app developers continue to push the boundaries of technology, but consumers’ expectation to demand more could be daunting for them. The rescue to this chaos can be found in the market of features-as-a-service. With API-providers going supportive, developing apps with key features have also turned out to be easier and faster. This method can be applied on a variety of apps; from map apps to social apps, to educational apps, and so on. API-providers are coming up with almost all sorts of APIs, for all sorts of apps.

Mobile Apps have come a long way since Super Monkey Ball first debuted on Apple’s App Store. In the past, developers used to write every part of the app. You were required to setup and maintain your own hardware, which was a noteworthy investment in app development. Of course, it also requires experts and expertise in multiple areas.

When the global app economy began to boom, a lot of these challenges were solved for the app developers. Now servers exist on Amazon Web Services instead of a data center, making primary investment affordable. The whole mobile app development process has also turned out to easier than ever before as things are being standardized by the market leaders like Google and Apple.

New players in the API market are providing the highly scalable and robust backend functionality on which mobile app developers can create the desired experience for their users.

Here are a few features-as-a-services that are being used by all developers over the world.

For search. It delivers a complete search-as-you-type experience for apps. It does not spans only to languages, but it also covers the auto-complete searches, geo-searches, and enables users to deploy a feedback loop based on the relevant metrics.
For messaging. This API takes care of all the messaging requirements of an app. From one-on-on and group chats to typing indicators, to message-read receipts, a layer can be applied to have almost all sorts of messaging features.
For social. If you need the social network in your app, Tapglue lets you do that with an ease. This API has a number of important components to take care of a personal profile, users, notifications, news feeds, likes, comments, in-app shares, and more.
For location. Many mobile application developers are using MapBox for an easy integration of location function in their apps. It delivers data to the app and renders it in real time. Apart from its stunning maps, the API provides turn-by-turn directions as well as search and geocoding features.
For deep linking.The API Branch.io is used by mobile app developers to simplify the process users hitting ‘invite’ or ‘share’ buttons and then a link is created which direct them to an actions like signing up for the app. It ties to data to the links so that you can use the info for on-boarding and content.

Childhood nutrition means giving essential nutrients to children. Childhood is a crucial stage in one’s life. The growing year of the children is very important for the development of their mind and body. It is very necessary to have a healthy diet containing vitamin, minerals and essential nutrients to young children. Example calcium and iron are necessary for their bones.

Childhood is important because children gain height, weight and they got all this with a healthy and nutritive diet. Due to the lack of a healthy diet, there is a problem of obesity in children which may lead to Osteoporosis, eventually. Proteins, fats, carbohydrate, trans fats, water, green vegetables and grains are the nutrition sources which impact on children’s growth.

New-born babies have a low level of energy, proteins and they get all this by a healthy diet. Mother’s breast milk for Infants (up to 6 months of age) is their entire diet. Milk contains all the nutrients required for baby’s health. Infants should be breastfed every 2 to 3 hours, at least 8-12 times a day. For babies who are intolerant toward milk, there is goat milk or lactose-free milk formulation also available in the market. This type of milk is fed 6 to 9 times a day.

In 6th month of age, solid food in the form of iron-rich cereal can also be given to children. In 12 months of age high nutritive diet become a high priority. Toddlers need calcium-rich food for the development of their bones. They need fibre-rich food to keep their heart-healthy and prevent constipation.

6-7-year-old children need a protein-rich diet example of egg, milk, peanut butter. Teenage children need more calories to make up for the body changes. In this phase of life, there is an increase in body fat and blood volume in girls, lean body mass in boys of this age group. Especially in girls, deficiency of iron is observed during their menstrual cycle.

It is important to increase calcium intake in boys and girls because it is important for bone and mass. Avoid sugary drinks, limit sugar and add more fruits in your children diet and modify recipes to make them tasty or healthy. Making the habit of eating healthy for your children is good for their health.

With proper nourishment, children grow healthy and strong. Training them good eating habits ensures a healthy lifestyle when they become adults. Although it becomes difficult to encourage them to eat green leafy vegetables or foods that they do not like. But presenting them every time with different recipe styles may help them make up their minds. Thus to reap the benefits of childhood nutrition in later periods of life.

When shopping for speakers online, you may have come across the term 3-way design. What are they and how do they differ from conventional speakers? Here, we take a closer look at 3-way speakers and the advantages they offer in home theatre systems.

A three-way audio speaker produces sound from three separate drivers or transducers. The three speakers i.e the woofer, mid-range and tweeter are optimized to deliver the greatest efficiency in their respective range of frequencies. In technical specifications or drawings, they may be denoted as LF (low frequency), MF (mid frequency), and HF (high frequency).

As the speaker drivers are optimized to work in a set frequency range, together they deliver clearer, more accurate sound along with reduced amplification requirements. To put things in perspective, most portable Bluetooth speakers usually have a coaxial or a full-range driver while many bookshelf speakers are 2-way and use only two drivers i.e. a mid-bass and tweeter driver.

How are 3-way speakers designed?
To optimize the speaker’s sound, an assemblage of electronic circuits called crossovers are integrated into the design. The crossover feeds each driver with a filtered frequency range of the audio signal from the amplifier or AV receiver. The crossover circuit feeds the woofer, midrange, and tweeter driver with only the low, mid and high-frequency signals respectively. This electronic wizardry is what ultimately forms the basis for a three-way speaker. In home theatre speakers, the crossover is usually placed inside the cabinet.

In professional audio, however, rack-mounted active electronic crossovers are used to distribute the frequency in either 2-way, 3-way or even 4-way configurations. The same principle is used in bi-amping or tri-amping. However, the amplification process happens after the frequencies are segregated via a crossover.

A look at the speaker drivers
So, do the three drivers differ in size and performance? Yes, they do. Let’s have a look at what sets them apart.

Woofer or Low-Frequency Driver
The woofer is the largest driver in the speaker, usually measuring between 5 to 12 inches in diameter. It generates low-frequency sounds in the bass range, such as drums, bass guitars, explosions and thunder etc. Most woofers have a cone either made of paper or plastic, a strong permanent magnet and a wire roll known as the voice coil. The same components are are used for the other transducer as well. However, they differ is terms of size, voice coil and cone material selection. From all the three driver variants, the woofer emanates the strongest sound thereby requiring relatively high amounts of power.

Mid-Range or Mid-Frequency Driver
In comparison to LF drivers, the mid-range driver is typically smaller ranging between 6 to 8 inches in diameter. It takes up the task reproducing mid-frequencies in which sonic elements like vocals, speech, and most musical instruments are nested comfortably. When heard in isolation, it will produce a reasonable sound. However, it will lack bass punch and treble brightness. Given how important the mid-frequencies are for the listening experience, many speakers often deploy more than one mid-range driver for added power, clarity and definition.

Tweeter or HF Driver
The tweeter is the smallest driver in the speaker. It usually measures no more than a few inches across. The drivers are typically made from highly conductive metals such as aluminium, titanium, magnesium, or even copper. It operates at the treble end of the audio spectrum, producing high-frequency sounds such as hi-hats, cymbals, percussions, flutes and others. Without a tweeter, the sound emanating from a speaker will lack brightness, clarity, and deliver a dull, muted and lacklustre sound.

The takeaway
Three-way speakers are preferred by audiophiles because of the clarity, tone and efficiency they deliver. Typically, most floorstanding speakers are 3-way design. However, there are 3-way bookshelf speakers available especially from high-end, audiophile-grade brands. If budget is not a constraint, we would definitely suggest buying a 3-way speaker for your home theatre system in India.
