Hydrocracking of virgin and waste plastics: A detailed review
The continuous increase in the demand for plastics is causing severe problems of managing increased waste plastic generation. The hydrocracking of plastic materials is considered an important method of converting these wastes into liquid fuels of high quality. Many attempts have been made in the search for a suitable catalyst [...]
Accelerating the transformation to a green university: University of Bahrain experience
Many universities are striving to have an environmental impact on the society as they are considered as small communities aiming to be eco-friendly and having low CO2 emission. This concept has been emerging after the worldwide concern on the ozone depletion issue and global warming. As a result, many titles [...]
Modeling recovery rates of corporate defaulted bonds in developed and developing countries
This paper examines the determinants of recovery rates of corporate defaulted bonds in the emerging markets. We use data on defaulted bonds from Moody’s ultimate recovery database over the period 2005–2015 to experiment the impact of the borrower characteristics added to the macroeconomic and the bond market conditions on recovery [...]
A detailed statistical study of heterogeneous, homogeneous and nucleation models for dissolution of waste concrete sample for mineral carbonation
One of the key issues associated to mineral carbonation is the slow kinetic rate of leaching process. Hence it is highly important to study the kinetics of the leaching process in detail. This paper deals with the detailed analytical and statistical studies of calcium leaching from waste concrete sample. For [...]
Toward sustainable development: Lessons from vernacular settlements of Sri Lanka
From modern urban perspectives, indigenous housing practices are regarded as undeveloped, backward, and require improvements. They may be valid for measuring on the basis of standards alien to the communities. However, these perceptions have obfuscated the appreciation and potential adoption of holistic, culturally relevant, and traditionally tested approaches to planning [...]
Characterizing temporal variability of PM 2.5 /PM 10 ratio and its relationship with meteorological parameters in Bahrain
The Kingdom of Bahrain is ranked in the top 10 most urban ambient air polluted countries in the world due to high particulate matter (PM) concentrations. The main objective of this article is to analyze comprehensively long-term temporal (annual, seasonal, and monthly) trends of PM 2.5 /PM 10 ratios using [...]
Cyber security challenges of deploying IoT in smart cities for healthcare applications
As technology improves at an astounding rate, cities have to improve their services in terms of safety, healthcare, transportation, and the overall welfare of their residents. Internet of Things (IoT) play a major role in the infrastructure of a smart city by gathering and processing data from distributed sensors to [...]
Road lane-lines detection in real-time for advanced driving assistance systems
In this paper, a fast and reliable lane-lines detection and tracking technique is proposed. The proposed technique is well suited to be used in Advanced Driving Assistance Systems (ADAS) or self-driving cars. The main emphasis of the proposed technique in on simplicity and fast computation capability so that it can [...]
Tuning of PID track followers for autonomous driving
In this paper, a Proportional-Integral-Differential (PID) controller that facilitates track maneuvering for self-driving cars is proposed. Three different design approaches are used to find and tune the controller hyper-parameters, one of them is specifically proposed in this paper for this specific application. The proposed controller uses only the Cross-Track-Error (CTE) [...]
Application of artificial neural networks for exploratory analysis of small dataset
This study aims to explore the use of Artificial Neural Networks (ANNs) for estimating the relationship between accidents and other variables with a small dataset. ANNs have not been used to explore relationships between variables, especially for road accidents which have small datasets. Analysis of road traffic accidents is often [...]
