“The term ‘holistic’ refers to my conviction that what we are concerned with here is the fundamental interconnectedness of all things”. . . . “I see the solution to each problem as being detectable in the pattern and web of the whole. The connections between causes and effects are often much more subtle and complex than we with our rough and ready understanding of the physical world might natur...

Systems engineering is a discipline with methods and techniques to address complex problems. We want to study how Systems Engineering methods can help to address today’s grand challenges, such as the energy problem. The first step is problem definition which aims at articulating the problem in its context as clearly as possible. Humanity will have to cope with the energy problem, one of the mos...

This paper focuses on the challenges of modeling cyber-physical systems that arise from the intrinsic heterogeneity, concurrency, and sensitivity to timing of such systems. It uses a portion of an aircraft vehicle management systems (VMS), specifically the fuel management subsystem, to illustrate the challenges, and then discusses technologies that at least partially address the challenges. Spe...

Technological developments and changes in business process context pose new challenges for effective management of business processes. Business process modeling is one of the most important area in business process management. Business process modeling is used to graphically visualize the operations of a business process for a better understanding and different analyses. These new challenges ar...

In this paper, the experiences of incorporating parametric modeling methodologies in a computer aided design course are introduced. This course aims at sophomore and junior mechanical engineering students. Students are expected to understand the fundamentals of solid modeling, incorporate design intents in modeling processes effectively, and master basic skills of using commercial software for ...

This paper summarizes the findings and recommendations of a recent panel on Future Directions in Control, Dynamics, and Systems, sponsored by the US Air Force Office of Scientific Research. A set of grand challenges that illustrate some of the recommendations and opportunities are provided. Finally, the paper describes two new courses being developed at Caltech that are aligned with the recomme...

One of the grand challenges for society is global security in food and nutrition. The ‘‘perfect storm’’ metaphor has been used by Sir John Beddington to describe the scenario that wemight be heading for, with simultaneous shortages for food, water, and energy within the foreseeable future. This Select highlights the need for a truly multipronged approach across scientific disciplines and countr...

The results for heavy-light mesons are summarized in Table 1. The results presented here are based on the same statistical sample, consisting of 102 quenched configurations at β = 6.0 with lattice size 16 × 48, as used in our study of fB and fBs [1]. The details of the NRQCD action, the evolution equation for calculating the heavy quark propagator, the method used for setting the lattice scale,...
