TL;DR: In this article, an enhanced test system (RTS-96) is described for use in bulk power system reliability evaluation studies, which will permit comparative and benchmark studies to be performed on new and existing reliability evaluation techniques.
Abstract: This report describes an enhanced test system (RTS-96) for use in bulk power system reliability evaluation studies. The value of the test system is that it will permit comparative and benchmark studies to be performed on new and existing reliability evaluation techniques. The test system was developed by modifying and updating the original IEEE RTS (referred to as RTS-79 hereafter) to reflect changes in evaluation methodologies and to overcome perceived deficiencies.

Abstract: The Yen–Mullins model, also known as the modified Yen model, specifies the predominant molecular and colloidal structure of asphaltenes in crude oils and laboratory solvents and consists of the following: The most probable asphaltene molecular weight is ∼750 g/mol, with the island molecular architecture dominant. At sufficient concentration, asphaltene molecules form nanoaggregates with an aggregation number less than 10. At higher concentrations, nanoaggregates form clusters again with small aggregation numbers. The Yen–Mullins model is consistent with numerous molecular and colloidal studies employing a broad array of methodologies. Moreover, the Yen–Mullins model provides a foundation for the development of the first asphaltene equation of state for predicting asphaltene gradients in oil reservoirs, the Flory–Huggins–Zuo equation of state (FHZ EoS). In turn, the FHZ EoS has proven applicability in oil reservoirs containing condensates, black oils, and heavy oils. While the development of the Yen–Mullin...

TL;DR: A trial assessment of whether students can program was developed and a framework of expectations for first-year courses and suggestions for further work to develop more comprehensive assessments were developed.
Abstract: In computer science, an expected outcome of a student's education is programming skill. This working group investigated the programming competency students have as they complete their first one or two courses in computer science. In order to explore options for assessing students, the working group developed a trial assessment of whether students can program. The underlying goal of this work was to initiate dialog in the Computer Science community on how to develop these types of assessments. Several universities participated in our trial assessment and the disappointing results suggest that many students do not know how to program at the conclusion of their introductory courses. For a combined sample of 216 students from four universities, the average score was 22.89 out of 110 points on the general evaluation criteria developed for this study. From this trial assessment we developed a framework of expectations for first-year courses and suggestions for further work to develop more comprehensive assessments.

TL;DR: A review of the history of research on chimera states and major advances in understanding their behavior can be found in this article, where the authors highlight major advances on understanding their behaviour.
Abstract: A chimera state is a spatio-temporal pattern in a network of identical coupled oscillators in which synchronous and asynchronous oscillation coexist. This state of broken symmetry, which usually coexists with a stable spatially symmetric state, has intrigued the nonlinear dynamics community since its discovery in the early 2000s. Recent experiments have led to increasing interest in the origin and dynamics of these states. Here we review the history of research on chimera states and highlight major advances in understanding their behaviour.

Abstract: Failure of metals still exists in our midst. This problem has been around for many a year and yet no full explanation exists. We have made great strides in understanding its many component parts but the path is still strewn with a number of obstacles. Fatigue consists of a number of different facets which require a combined effort of analysis and experimentation. This unique book covers a number of different members of the fatigue family and goes into detail on a number of them. The book consists of 17 chapters, each chock full of information. The initial chapter considers the role of failure prevention in mechanical design and provides some of the prime design objectives. Chapter 2 discusses the various modes of mechanical failure. Chapter 3 is the heart of the book and treats the strength and deformation of engineering materials. This includes elastic and plastic response, fracture and a good section on dislocation theory. The author touches upon elastic fracture and elasto-plastic fracture mechanics. No mention is made of J integral which is an important aspect of plastic fracture mechanics. Chapter 4 treats state of stress and various parts making up this important concept. Chapter 5 focusses upon relationships between stress and strain. The author illustrates the relationships between elastic and plastic stress-strain. The author then spends time in developing the combined stress theories of failure. This includes the maximum normal stress theory, Tresca-Guest theory, Beltrami theory, VonMises Hencky (distortion energy) theory and Mohr's failure theory. This is a very well "put-together" chapter, concise but informative. Chapter 7, the most lengthiest, treats high cycle fatigue. Beginning with the nature of fatigue and fatigue loading, it progresses to S/N relationships and the various factors which affect the S/N curves. This includes geometrical considerations, size effects, residual stress effects with brief mention of corrosion and fretting. We next delve into nonzero mean stress and multiaxial fatigue stresses. The chapter concludes with the uses of the various components of multiaxial fatigue stresses as applied to fatigue stresses. This is an excellent chapter and should be read by all concerned parties.
