Generalized models based on nonparametric model for reliability prediction are free of assumptions.

Damage detection is one of the most important task to predict damage at the early stage. There are many different methods can be used in damage detection, however vibration based damage detection technique is considered ad an efficient approach in this feiled. Whereas the dynamic response can reflect the hidden effect of internal damage even at early stage.

Air conditioning applications in public places are considered one of the most important applications of heating, ventilation and air conditioning (HVAC), with a great diversity of heat sources, water vapour and carbon dioxide due to the high number of occupants of the space. Therefore, the current study is devoted to numerically investigating the air distribution in various public places such as houses of worship, mosques in particular, cinemas, theatres, offices, government buildings, public libraries, classrooms and conference rooms.

Gearbox is an important power transmission component in a wide range of industrial applications. Wear is a common failure mode induced between the contact surfaces of the engaged gear teeth, which result in higher vibration and noise in the gearbox. The early detection of wear is very important for reliable working and better operational performance. Monitoring of gear vibration signature can develop early detection and accurate diagnosis of gear wear fault, and thereby extend the life span of the transmission system. This study focuses on applying an early detection of gear wear that was naturally produced in industrial gearbox system.

The graphene, which is usually used as a reinforcement in composite materials, has been a major research topic in different industrial and engineering applications. These nano-composites possess excellent material characteristics and are utilized in different applications, for example, in optical electronics, energy storage and advanced nano-composite.

This seminar in intended to is focuse upon the formulation of an environmentally-friendly lubricant using vegetable oil with various composition of petroleum base stock. The physico-chemical and tribo-chemical properties of the formulated oil have been analyzed using multiple standards apparatuses.

The security management of healthcare worldwide increases their attention due to the high risk of COVID-19 medical waste. The poor medical waste management in Iraq before and during COVID-19 cause a huge environmental risk and can be a possible source of reappear infection.

The metal foam (MF) can improve convection heat transfer and disrupts the boundary layer growth due to the large contact area with the cooling working fluid and tortuous flow paths which improve the mixing of working fluid.

The thermo-magnetic generation mainly depends on the magnetic materials. Due to heating up and cooling down around the specific temperature ( Curie point), the material works as a magnetic switch (on/off). Thought out this process, power generation can be achieved.

The "shear-lag" phenomenon is frequently used to describe the interplay between axial and shear stress around fracture points or geometric discontinuities and provides ongoing load transfer after the initial compromise of a structure.
