Flipped classroom is an academic model in which the typical homework and lecture elements of a course are changed. Students can view short class related lecture videos for preparation before the class is started. This class related video lecture is the key ingredient of the flipped classroom and these are the videos mainly created by the instructor and uploaded online or it can be selected from an online repository.

Voice and speech recognition form a smaller part of the biometric systems. Speech recognition refers to the process of converting spoken words into digitally modified and stored set of words with the help of telephones and microphones.The speed which measures how well the software matches with a human speaker and accuracy which measures the number of errors made during the conversion of spoken words into digitalized data, are the two parameters which assess the quality of a speech recognition system. The voice recognition system analyses the identity of the speaker behind a particular voice. It analyses the voice between different speakers by studying the behavioral patterns of different people, such as the concerned person's voice pitch, speaking style, accent and others, and also studies the shape and size of the mouth and throat of the concerned person.

Advancement of sensor technology, cloud technology and advanced wireless technologies have been created new opportunities in the market. As everyone knows that many enterprises are seeking for new innovative solutions to reduce their operational cost and increase ROI. Enterprises need to understand that which are impacting on reduce operational cost. Therefore, most of the enterprises are moving towards remote asset management solution to reduce their operational expenses.

Scratch Resistant coating or abrasion resistant coating is a coating or a film which is applied to optical displays, optical lenses, instruments, signs, packaging of cosmetics and on a range of surfaces creating to a protective layer & forming a bond to save it from scratches from physical and chemical effects. Wearing of the surface usually occurs when a rough surface comes in contact with the components surface resulting in undesired removal of material from the surface of the component. Scratch resistant coating is used to modify or improve hardness of a component's surface thereby increasing its lifespan and performance. Special scratch resistant coating and adhesives have been developed   which provides outstanding scratch resistant.

Off-Highway diesel engines refer to those engines that are designed to meet the needs of applications across sectors such as construction, mining and industrial. These engines deliver stable performance in extreme conditions such as dust, vibration, high altitudes and harsh climatic conditions thereby improving productivity and enhancing profitability. Such engines are also used in off-highway vehicles such as excavators, cranes, mixers, backhoes and forklifts in performing various tasks. These diesel engines are configured each time to meet the heavy-duty requirements for specific applications.

A reflector antenna is a device which can reflect electromagnetic waves and can present as an individual device used for redirecting RF (radio frequency) signals and also can be incorporated as a portion of the antenna assembly. A simple reflector antenna is combined with two different components, a reflecting surface and a small feed antenna, which is located at reflector's focal point. Similarly, a complex reflector antenna consists of the secondary reflector at the focal point, which is feed by a primary reflector. These type of reflectors are known as dual-reflector antennas. There are various types of reflector antennas such as parabolic, cylindrical, corner and spherical reflector antennas.

With the rising fuel prices as a result of increasing demand and diminishing supply, there has been rise in the need to choose a cost effective fuel for vehicles. Despite its higher price than gasoline, diesel proves to be highly efficient and cost effective. In addition, diesel enables extraction of more energy as compared to same volume of gasoline. Furthermore, diesel has a higher boiling point and is oilier than gasoline which improves engine efficiency. Thereby, diesel has become a preferred choice for both heavy-duty and light-duty vehicles across the world. Moreover, light diesel vehicles have reduced carbon emissions as compared to similar gasoline powered vehicles. Light duty diesel vehicles are widely used across the world for personal and commercial purposes. Light duty vehicles include various passenger cars, sports utility vehicles (SUVs), light weight trucks, pick-up trucks and minivans. Such vehicles are widely accepted owing to factors such as low-end power, highway driving, reliability and improved towing and transportation of goods. With more number of automobile manufacturers focusing on diesel vehicles, customers are able to choose from a wide range of vehicular design and specifications. This has further driven the popularity of light diesel vehicles across various customer segments.

Manufacturing facilities use complex machineries that operate at a high speed. Companies are also making efforts to make their assembly lines faster and more efficient, increasing the speed of functioning of the line. This also gives rise to a scenario where workers working on the assembly lines are at a constant risk of getting hurt by machines performing activities such as pressing, cutting, and welding. Manufacturing units that incorporate hazardous machineries are also incorporating more safety measures to ensure the safety of their workers.

A bug tracking system is a software application that helps keep track of tested software bugs in software development projects. It is a type of system that tracks issues in a software. With a bug tracking software, an issue that could be anything from a simple customer question to a comprehensive technical report of a bug or an error, can be easily tracked. Generally a bug tracking system or software offers the user with a technique to report an issue or bug and track advancement of its resolution, and identifies who is responsible for resolving the problem. Moreover, it also permits the system manager to modify the tracking method so that excessive certification on the part of problem solvers does not turn out to be wastage of time. Various organizations use bug tracking applications, comprising IT help desks, manufacturers, software developers, and other service providers.

Phenoxyethanol is a colorless, clear and oily liquid that is used in cosmetic products such as sunscreen and skin creams. Phenoxyethanol is produced by reaction between ethylene oxide and phenol at elevated pressure and temperature. Phenoxyethanol has intermediate water solubility and shows moderate evaporation rate. Phenoxyethanol is a bactericide and used simultaneously with ammonium compounds as a substitute for sodium azide due to its less toxic properties. In addition, phenoxyethanol is non reactive with lead and copper. It is used in numerous applications such as vaccines, cosmetics and pharmaceuticals products as a preservative. Phenoxyethanol is necessary to enhance the shelf life of cosmetics and personal care products. Phenoxyethanol can also be used as an alternative to potentially harmful formaldehyde-releasing preservatives. The activity of the preservative phenoxyethanol is effective in inactivating gram-positive and gram-negative microorganisms and yeast.
