User care at home is a matter of great concern since unforeseen circumstances might occur that affect people's well-being. Technologies that assist people in independent living are essential for enhancing care in a cost-effective and reliable manner. Assisted care applications often demand real-time observation of the environment and the resident's activities using an event-driven system. As an emerging area of research and development, it is necessary to explore the approaches of the user care system in the literature to identify current practices for future research directions. Therefore, this book is aimed at a comprehensive review of data sources (e.g., sensors) with machine learning for various smart user care systems. To encourage the readers in the field, insights of practical essence of different machine learning algorithms with sensor data (e.g., publicly available datasets) are also discussed. Some code segments are also included to motivate the researchers of the related fields to practically implement the features and machine learning techniques. It is an effort to obtain knowledge of different types of sensor-based user monitoring technologies in-home environments. With the aim of adopting these technologies, research works, and their outcomes are reported. Besides, up to date references are included for the user monitoring technologies with the aim of facilitating independent living. Research that is related to the use of user monitoring technologies in assisted living is very widespread, but it is still consists mostly of limited-scale studies. Hence, user monitoring technology is a very promising field, especially for long-term care. However, monitoring of the users for smart assisted technologies should be taken to the next level with more detailed studies that evaluate and demonstrate their potential to contribute to prolonging the independent living of people. The target of this book is to contribute towards that direction.

Horticulture not only deals with ornamental plants but also with their medicinal values.Aloe Vera having immense potential to prove itself not only an ornamental plant but also as a medicinal plant and can be used for curing skin diseases as well as in curing of cancer patients. Therefore this plant can't be ignored to cultivate it in fields. This book, therefore, provides an idea how to cultivate Aloe Vera in field and to get maximum gel production and Aloe juice that are used for medicinal purposes. Different parameters are being critically analysed like Gel per leaf, Plant height and leaf weight etc. Nitrogen and the affect of water are being checked on the production of Aloe gel and all other contents. Therefore the book is special in all its fields of concerned especially the medicinal aspect of horticultural plants. The book provides an attention towards a plant, being ignored to be cultivated in fields, of so much importance and that can be an earning source for the farmers because Aloe Vera has a wide range of uses in our daily life.

Soil comprising the pedosphere is positioned at the interface of the lithosphere and biosphere with the atmosphere and hydrosphere. Soil is considered a three phase system, consisting of solid, liquid, and gas. The solid phase consists of mineral and organic matter, including living organisms. The liquid phase is known as the 'soil solution', and is the phase from which plants take up nutrients. The gaseous phase is important for supplying oxygen to the roots for respiration. Agrictural soil of the study area is very fertile and is a main source of economy for local population. This deals the investigation of heavy metal in the soil of study area.The effect of local transportation on the productivity of vegetables have also been discussed.
