Complex enterprise environments consist of globally distributed infrastructure with a variety of applications and a large number of activities occurring on a daily basis. This increases the attack surface and narrows the view of ongoing intrinsic dynamics. Thus, many malicious activities can persist under the radar of conventional detection... Continue Reading
A novel user-level scheduling, along with a specific data alignment method is presented for matrix multiplication in cache-coherent Non-Uniform Memory Access (ccNUMA) architectures. Addressing the data locality problem that occurs in such systems alleviates memory bottlenecks in problems with large input data sets. It is shown experimentally... Continue Reading
In the past two years, Saudi Arabia has dramatically extended its active labor market policies in order to address the issue of growing youth unemployment and low Saudi participation in the private sector workforce. This paper studies the 2011 introduction of the Nitaqat program, which imposed a quota system for Saudi hiring at private firms.... Continue Reading
In recent years, the interest in modeling complex engineering systems has grown rapidly. Due to their highly nonlinear nature coupled with their critical importance, the task of modeling such systems becomes a high-risk, high-payoff endeavor. There are many complexities associated with understanding and modeling the dynamics of such systems,... Continue Reading
Extensive theoretic work attempts to address the role of social norms in describing, explaining and predicting human behaviors. However, traditional methods of assessing the effect can be expensive and time consuming. In this work, we utilize data generated by the call detail records (CDRs) and geo-tagged Tweets (GTTs) as enabling proxies for... Continue Reading
In this paper we present the Collaborative Planning Interface (CoPI), a web-based multiuser collaboration interface platform for planning of complex systems. The interface provides analytical and visualization components to support decision makers. The Interface is designed using a user-centered design approach, while considering existing tools...

Stakeholders in the Kingdom of Saudi Arabia are concerned about the sustainability of the country’s water system. The Ninth Development Plan (2009-2014) formulates a number of policy directives to make the water system more sustainable. Assessing whether these policies can improve the degree of sustainability of the water system is a... Continue Reading
The performance of a large infrastructure project depends on not only technical design choices, but also contractual and other economic arrangements. These choices and arrangements interact in the context of uncertainty to result in the project’s realized performance.
Design of future hard infrastructure must consider emergent behaviors from cross-system interdependencies. Understanding these interdependencies is challenging due to high levels of integration in high-performance systems and their operation as a collaborative system-of-systems managed by multiple organizations.
The Kingdom of Saudi Arabia (KSA) has experienced rapid growth in peak load and electricity consumption over the past decade. Under current demographic and economic trends, peak load is projected to nearly triple by 2032, which will require massive new investments in both conventional and alternative generation capacity.
