In analyzing the reliability of a product, the quantity of interest is usually the time-to-failure. However, many products may degrade before failure, and it is possible to record the actual degradation on units as a function of time. The time-to-failure will be defined as the t…

Development stages of the Erbil Basin are poorly understood and the sustainable use of groundwater in the basin is uncertain. This study characterizes water sustainability and its significance through demonstrating the overexploitation and deficit rates of the groundwater supply…
Landfarming is one of the disposal methods used by oil companies to dispose of their generated oily sludge. Once in the soil, the sludge is subjected to biodegradation, leaching, and volatilization. Field studies were conducted in an arid region such as Saudi Arabia, the largest…
A combined analytical and experimental work is described to demonstrate the application of Laser Ultrasonic techniques for monitoring long term performance (Durability) of thick-section Pultruded FRP composites. Damage is induced in the material using both environmental and mech…
Defining the predominant cause of tropical deforestation is a major issue of contention in international politics. The present debate revolves around the role of indigenous slash-and-burn agriculture in propagating this destruction. This ancient system of farming has had the mis…
The scaling trends in CMOS technology and operating conditions give rise to serious degradation mechanisms such as Negative Bias Temperature Instability (NBTI) and Hot Carrier Injection (HCI) in MOSFETs, threatening the circuit and product lifetimes. The aging phenomena, on top …
The soudano-sahelian region is undergoing profound transformations that affect particularly the strategic sector of farming which is experiencing several social and territorial changes. The lack of knowledge about these transformations is a major obstacle for implementation of s…
Durability of the composite materials in marine environments has been investigated experimentally and with analytical and numerical methods. The main focus of this study is on the integrity of the fiber/matrix interface under seawater exposure. A single-fiber compression test sp…
Pipelines are susceptible to degradation over the span of their service life. Corrosion is one of the most common degradation mechanisms, but other critical mechanisms such as fatigue and creep should not be overlooked. The rate of degradation is influenced by many factors, such…
