Benefits of Using Software as a Service (SaaS)

SaaS stands for software as a service and it is one of the models of cloud computing. It can be considered as an on demand service. Because when an organization or an individual wants to use SaaS for a particular purpose they can avail the service from cloud service provider. The cloud service provides SaaS solution to different organizations for different purposes. It can be used by an organization for business activities or can be used by an individual for personal purpose.

It has become a most common hosting model where businesses are availing the services for their internal applications such as payroll processing, accounting, time tracking and billing, customer relationship management etc and for web based purposes like site hosting, design, website monitoring, ad-management adservers, content delivery networks etc. For the business organizations this service would be more beneficial because the SaaS applications are accessible anytime through any device. As the focus of a business is to make more customers/clients, Saas helps organizations to improve their business process and provide customers a better satisfactory service. It offers many benefits to businesses of all sizes and types.

Benefits of Using SaaS in your Business

  • SaaS helps in businesses to reduce the burden of responsibility and minimizes the workload. It integrates seamlessly with other softwares and also offers better customization to meet the specific needs of the business.
  • Comparing to traditional methods of installing the hardware and licensed software the usage of SaaS is very useful for SMBs. Since SaaS provider is responsible for complete infrastructure such as hardware, software and human resource to maintain it all, it lowers the costs of businesses.
  • Cloud service providers upgrade their services timely and are easily available for the user. And if a software is timely upgraded, dealing with a particular task will take less time. The service seekers need not worry about checking for monthly updates or upgrading the software to a better one. Saas provider is responsible for installing the patches and keeping the software updated with latest versions.
  • SaaS offers multi-tenancy infrastructure where single version of product is used to support multiple user groups. Here an application is shared among multiple customers running on the same OS, hardware and data storage. There are many applications that are available in this model and some of them are accounting software, time tracking software, Payroll systems, MS Outlook etc.
  • Since SaaS is a web based service it allows users to access the software easily from any place with internet capabilities. It allows people to work from anywhere outside the office using any device. This gives flexibility in working as people can get access through mobiles, tablets or other devices when they are away from the workplace.

Difference Between Traditional Desktop Web apps and Mobile Apps

Over the past few years, we have seen a tremendous increase in the adoption of smartphones for internet usage. In some countries, the web traffic from smartphones and tabs have exceeded the desktop computers. To compete with the existing mobile market, businesses are developing mobile versions of their existing applications. Mobile apps provide the flexibility of operation from anyplace whereas desktop versions of applications have restricted mobility. Both these two versions have their own specific benefits and drawbacks. Though both use similar technologies, there are few fundamental differences between mobile and traditional desktop apps.

Thick vs Thin clients

Traditional web applications use thick or fat client where a client-server architecture or network typically provides application access. In this design, some parts of the application are accessed from the client while others can be accessed from the server. However, mobile apps use thin clients where the applications depend heavily on servers for its access. Since most of the thin clients have low energy processors, flash storage, or memory, mobile apps are slow when compared to desktop traditional apps.

Network Bandwidth

Bandwidth is a major drawback in mobile apps as many of them use only lower 3G or 4G internet connection speed. Since tradition web applications use high network bandwidths, they are much faster and have higher performance. The low bandwidth is one of the reasons that mobile apps have extended user sessions and poor response times.

Remote Data Access

While using mobile apps, the users need to face many unique challenges in terms of data access which are not found in server or desktop environments. Since the remote data for mobiles is accessed through network connections which travel from tower to tower, the performance is low when compared to traditional web apps.

Computing Ability

Since smartphones and PCs have different CPUs they have different processing powers and memory storage. Hence, the computing performance of both the devices are entirely different. Smartphone CPUs are generally smaller and have limited computing ability. As mobile apps have only limited processing powers their performance will be comparatively lower than the desktop web applications.

Touch vs Click

Desktop applications offer better user experience because mobile devices have touch based inputs which are not always effective. Mobile users need to use their fingers for navigation from one page to another whereas desktop applications use keyboard or a mouse. While it is easy to navigate using a mouse for desktops, small-screened mobile devices require precision in touch for navigation.

Data Restrictions

When you are using mobile apps on your smartphone, you need to track data usage to see which app is using the most. Generally, mobile networks charge for the data that consumers use. If you are using more mobile apps on your smartphone, then you may end up paying higher bills to your mobile service. This is not the case with desktop web applications because they use optimizing techniques for caching of data.

How to prevent teeth from getting stained?

By nature we all have some flaws in our teeth. While some of the people feel bad about their broken or crooked arrangement, others worry about their dull or stained colored teeth. Our teeth can acquire stains with age or perhaps due to excess consumption of colored foods and beverages that are turning them into dark yellow tint. It is important to remember that only a pearly white teeth can make our smile bright and attractive. In order to achieve bright white teeth, people undergo many whitening treatments and follow certain precautions to protect their teeth from getting stained. There are certain tips that people can follow to avoid teeth staining and maintain their whiter smile.

Exposure to fluorides
Children at early young ages should avoid the usage of too many fluoride containing products. Getting exposed to fluoride will discolor the teeth or turn the teeth into dark or pale yellow colors. Generally dentists recommend fluoride containing toothpastes or mouthwash for children to keep their teeth healthy but excess utilization may also give adverse effects.

Staying away from stain causing foods
Studies have shown that people who consume coffee, tea, wine, berries, hard candies etc are more prone to tooth discoloration than the others who stay away from these foods. Initially the stains start with outer extrinsic surface but if proper care is not taken it can get deep inside the inner parts of the tooth pulp.

Using straw to drink beverages
While some people who strictly keep themselves away from the colored foods and drinks, others have no control on their food habits and become vulnerable to teeth problems. If you have a habit of drinking lot of beverages, it is better to use a straw which can keep the stain-causing colors away from your teeth.

Following good oral hygiene
Following a good regime of brushing, rinsing and flossing habits will reduce the risk of getting affected by the stained food. Many dentists suggest people to follow this process immediately after having food as it removes the food particles and stains that are stuck on the surface or inside the teeth.

Getting your teeth professionally checked regularly
Unless there is a major issue people generally do not prefer to go to the dentist for checkups and treatments. What they don’t realize is, having regular dental checkups will avoid the occurrence of major issues as in many cases these dental issues get identified at the early stage and are treated immediately. Hence, before complicating the issue of a normal stain into intrinsic tooth problem, it is better to have regular dental checkups for normal cleaning and whitening methods.

Avoiding tobacco and cigarettes
Prolonged usage of tobacco, cigarette or cigar can cause deep stains on your teeth and it may require some special procedures to totally get rid of them. Beyond these risks, it can also lead to other gum diseases and oral health problems. Even though people are aware of the drawbacks, they are not able to quit because they are habituated to it. The first step towards cessation process is getting some professional help who can support you to come out of this addiction.

Tests Performed On Draft Fans

jet fansThe basic requirement for testing draft fans is to find the amount of air and exhaust gases flowing out of the furnace or boiler. Draft fans may accumulate some dust particles on the blades of the fan, resulting in lower flow rates of the air and exhaust gases. Strength test is performed based on the rigidity of the system to determine the amount of stress that the system can withstand.

Measuring air and gases flow rate

  • The main purpose of the draft fans is to either provide fresh air into boiler or to remove the exhaust gases from it.
  • Flow rate can be measured in many ways. Simple way to measure is by knowing the pressure difference in the boiler between induced draft and forced draft.
  • If the pressure head, kinetic head and potential heads are known then the mass flow rate  is known by which the flow rate of the air and gases are calculated.
  • In modern world there are some advanced devices which use electric energy to find out the flow rate of the gases when placed on their path of motion.

Strength Test

    Centrifugal Fan

  • The flow rate of the fans are tested after they are installed in the boiler. The strength test can be performed any time either before installing or after installing.
  • Strength test determines the amount of stress that can be hold by the system.
    A system may be subjected to either thermal stress or structural stress.
  • The thermal stresses are induced as a phenomenon of the conduction due to temperature difference among the parts of the fan.
  • Structural stresses are induced due to the action of various factors such as vibrations caused at the lower speed of the fans.
    The thermal stresses are tested on the conditions of conduction, convection, radiation and heat flux.
  • The structural stresses are tested depending on the strain energy and the Young’s modulus of the material used.
  • In the convection method they are tested using a model of the system and the model is applied for real conditions such as temperature and pressures in case of thermal stresses, and ultimate stress & yield stress in case of structural stress distribution.
  • The above mentioned testing may sometimes result in destruction of the system.
  • Due to advancement of computer technology there are many software’s which use numeric methods such as FEA to find the thermal and structural stress of the system.
  • By the aid of these numeric systems one can give the exact values of the stresses induced in the system.

In industries, testing is very important as it increases the life of the system. If the system is not tested thoroughly, there can be huge loss of money or human life in the organization.

Working of a Ventilation System

The working of a ventilation system is broadly explained based on two phenomenon in the system i.e. inlet and outlet of air inside the work place and the circulation of the air inside the work place. These two will decide the working of the system. For different kinds of ventilation systems, the operations may not be the same.

Inlet and Outlet of air in the Ventilation System

  • The removal of contaminated air and the inlet of fresh air is the main use of the ventilation system. This can be done by the aid of fans and tubes. When the fans are in action, they will change the direction of air or let the motion of the air to be fast.
  • Then the air with the motion is allowed to pass through the series of tubes where it is moved out of the working environment as in case of local exhaust or it is mixed with the fresh air in order to make the contaminated air less toxic in the working environment.
  • The inlet and outlet movement of the gas or the contaminated air is done by fans and the gases are captured due to the presence of a small nozzle type arrangement called as hood which will not allow the gases to exit from the tubes.
  • Take the case of dilution system, in which the inlet air is let into the ventilation system and just made to move from one side of the working place to the other place where it is let out of the tubes by the aid of the exhaust fans.
  • Similarly, take the case of the local exhaust system, in which the air is let in at a place and just let out from the other place. Air in the local exhaust system is also subjected to air cleaning.

Circulation of air inside the building

  • The circulation of air is to be done in dilution type of ventilation system. The circulation just reduces the concentration of the toxic air inside the working area.
  • Circulation of air also involves heat recovery system which maintains nominal temperature in the working area. The circulation is also done by the aid of a blower which will allow the air, in more concentrated area to move to the area in the lower contaminated air or fresh air.
  • The main advantage of air circulation is, we need not take fresh air every time from the surroundings and liberate the contaminated air outside. It also saves the excess work.
  • Circulation is also performed by creating low pressure region within the working environment so that the contaminated air can be mixed together attaining equilibrium of the pressure.

In a ventilation system, we can either circulate air inside or move the contaminated air completely outside the work place or we can have both in a single system.
