Big data refers to large and complex information in electronic format that is difficult to manage using conventional software, hardware, or data management tools. This information is tremendous in terms of its volume, variety, and velocity. In the healthcare industry, this includes a wide variety of data such as patient data in electronic medical records; clinical data; data from sensors monitoring vital signs; and emergency care data for news feeds. It also includes social media data from Facebook, Twitter, and blogs, and data from clinical decision support systems such as medical imaging, pharmacies, labs, prescriptions, and insurance records.

An RTU is a control device that helps the master device (SCADA) to monitor and communicate with devices in the grid placed in different geographical locations. RTUs are used in a broad range of electrical and process automation devices wherein supervisory control and data acquisition (SCADA) is required to monitor and control the equipment. RTUs collect data from field equipment and communicate commands from the master device. This is done through a wired connection (telephone line, cables, or Ethernet) or wireless connection. The operators receive data in real time so that they are aware of the complete grid situation and can make any changes to the grid when required. RTUs increase automation in substations, leading to optimal distribution of power. They also correct any anomalies that may lead to loss of power in transmission and distribution (T&D), reduce equipment damage, and improve power quality and reliability. RTUs can be used to control and monitor water treatment and distribution plants, power T&D operations, and oil and gas lines.

Digital education classroom models consist of digital curriculum that have become popular on account of their convenience and flexibility. This has led to educational institutions adopting e-learning for both K-12 studies, higher studies, and skill-based trainings. Digital education content is available for educational institutions in standard and customized formats. Institutions can procure the content either through the payment of fees or the content can be accessed through subscriptions.

Automobile manufacturers globally are focusing on the usage of technologically advanced drivetrain and safety systems to minimize accidents (and mitigate the impact of accidents on both passengers and pedestrians). Consequently, OEMs developed MWD systems to ensure enhanced control and stability of vehicles. A drivetrain is a collection of components that carry power to the driving wheel. 4WD and AWD are the systems used to allow a vehicle to receive the necessary torque from the engine. AWD systems have differentials whereas 4WD systems do not, as a result, the latter can be used as part-time 4WD systems. In this mechanism, the torque goes to the transfer case and is then directed to the front and rear axles.

Mouth ulcers are sores formed in the mucous membrane of the oral cavity. They are noncritical and do not pose serious harm to the health of an individual. Mouth ulcers are formed because of oral injuries or they may arise as a result of an underlying disease. They may be associated with intense or moderate pain. The causes of mouth ulcers are stress, injury, infection, allergy, genetic predisposition, or nutritional deficiencies. The etiology of the disease depends upon the cause, which can be identified and treated upon diagnosis. Ulcers normally heal by themselves in 10-14 days, but medical treatment is usually sought if the condition persists.

Li-ion batteries are mainly used in devices such as laptops, smart phones, notebooks, and tablets, owing to their high energy density and rechargeable properties. The newage battery is also finding increasing use in EVs, especially in tandem with the growing popularity of BEVs and PHEVs. Li-ion batteries consist of one or more energy generating compartments called cells. Each cell has three components: a positive electrode (cathode), a negative electrode (anode), and an electrolyte between the two electrodes.

Generators are backup devices that provide temporary AC or DC power using the supplied fuel (gasoline, diesel, or gas). They are used as emergency power source for residential, commercial, and industrial applications. A typical generator is powered by a fuel engine. Portable generators provide AC power for standby non-hardwired applications. Although the low-end models support only a few basic home appliances, the high-end portable generators can provide backup AC power to an entire house. Apart from the residential sector, these generators are widely used in commercial buildings as well as industrial and infrastructure sites. They provide power supply in areas that lack grids.

Traditionally, the contracts between businesses were documented on paper and presented to the concerned parties for any revisions or amendments, following which the final version was prepared. Considering the high levels of negotiation involved in the writing of the final contract, companies involved their lawyers and legal departments in the process. The lawyers reviewed these contracts manually, which is a time-consuming process and prone to errors. With time, technology has evolved and companies have started managing their contracts via electronic media. The electronic format of contracts has not enhanced the visibility of contracts, resulting in poor management of contracts. However, with the adoption of CLM software, companies have enhanced their contract visibility, and are able to provide timely information to their legal teams, thus enhancing their decision-making processes.

A femtocell is a small and lightweight cellular base station designed to increase the signal strength and coverage area of mobile networks indoors and outdoors. It offers prompt data connections and in-building voice and data services, fewer dropped calls, and improved mobile voice quality to enterprises and residential consumers. The femtocell technology can be easily deployed because of its low-power consumption, IP backhaul, and self-optimization capabilities. A large number of MNOs are using femtocells to reduce network costs and increase their market share and revenue. One feature of femtocells is that subscribers do not need any dedicated user equipment (UE) to use them.
