There is an increasing trend to use commodity microprocessors as the compute engines in large-scale multiprocessors. However, given that the majority of the microprocessors are sold in the workstation market, not in the multiprocessor market, it is only natural that architectural features that benefit only multiprocessors are less likely to be adopted in commodity microprocessors. In this paper, we explore multiple-context processors, an architectural technique proposed to hide the large memory latency in multiprocessors. We show that while current multiple-context designs work reasonably well for multiprocessors, they are ineffective in hiding the much shorter uniprocessor latencies using the limited parallelism found in workstation environments. We propose an alternative design that combines the best features of two existing approaches, and present simulation results that show it yields better performance for both multiprogrammed workloads on a workstation and parallel applications on a multiprocessor. By addressing the needs of the workstation environment, our proposal makes multiple contexts more attractive for commodity microprocessors.

Students struggle to understand many concepts in statistics such as when to use the appropriate inferential statistic to run a statistical analysis. This study was the first of its kind to incorporate interleaved practice, a form of distributed practice, into a Statistics in Psychology course to see if this educational intervention can help students better understand statistical concepts and reduce negative attitudes towards statistics. The study was conducted by having students in Statistics in Psychology at University of Massachusetts Dartmouth be exposed to interleaved homework assignments (n = 18) or traditional blocked homework assignments (n = 13) during the Fall 2023 semester. Results showed marginal effects in which interleaved practice led to better performance on some quizzes. Results also showed a significant interaction in which interleaved learning led to students having more positive attitudes about the value of statistics at the end of the semester as compared to the beginning, while blocked learning led to students having more negative value attitudes at the end of the semester as compared to the beginning. Based on the results I concluded that interleaved practice has high potential of helping students perform better on certain assessments in Statistics in Psychology such as quizzes, as well as promoting more positive attitudes towards the class. Thus, future Statistics in Psychology instructors may decide to implement interleaved homework assignments in their sections to help their students perform better and increase their feeling of value towards the course. Keywords: interleaved learning, blocked learning, learning intervention, psychology, statistics, statistical attitudes.

In this chapter the ways in which Cavell’s death was reported by the British Foreign Office to the national press, and then widely disseminated, are examined. The responses of newspaper editors, clergy, and members of the nursing profession are considered. The reaction to Edith Cavell’s execution was almost uniformly patriotic, calling on men to enlist in order to avenge what was seen as her “murder”. A few pacifist voices were raised, but, for the most part, the British response appears to have been markedly consistent. For the British Bureau of Propaganda, Cavell’s death was an opportunity to present the German military high command as brutal, and the view that the Germans were essentially a brutal race found its way into the letters pages of newspapers and journals. Members of the German military government responded through their own carefully worded press releases, claiming that Cavell had been legally tried and convicted under martial law—but both British and US legal experts countered these claims by observing that her rights as an accused person had not been properly protected. A large number of biographical writings was produced during the twentieth century; some of these drew on apocryphal newspaper stories as well as on the testimony of individuals who knew Cavell. In the last 20 years there have been shifts in perspectives on Edith Cavell, with greater attention being paid to the realities of her resistance work, and with a greater tendency to interpret her work—both as a nurse and as a supporter of the Belgian resistance—from a feminist perspective.

In this paper, we investigate the costs and benefits of implementing memory interleaving in software. As our main contribution, we compare software memory interleaving to row-major allocation and logarithmic broadcasting. Our analysis demonstrates the clear superiority of software interleaving over row-major allocation in the presence of memory contention. Our analysis also indicates that the choice between software interleaving and logarithmic broadcasting is less clear, as it depends both on the type of synchronization used and the number of processors. We conclude that, on large-scale multiprocessors, software memory interleaving and lock-based synchronization is the most effective combination for reducing memory contention in matrix computations.

An interleaving device for processing energy signals between various logic devices has a first number of spaced energy carrying layer mateials. Each of the first layer materials has a number of juxtaposed conduits passing energy signals through which are passed. Each of the conduits has a longitudinal axis substantially parallel to a diagonal of each of the first layers. A second group of energy carrying materials is arranged between adjacent ones of the spaced first layer materials. Each of the second layer materials has a number of juxtaposed conduits through which the energy signals are also passed. Each of the conduits in the second layer has a longitudinal axis substantially parallel to a diagonal of each of the second layer materials and substantially perpendicular to the axes of the conduits of the first layer materials.

Interleaving planning and execution is the practical alternative to the problem of planning off-line with large state spaces. While planning via symbolic model checking has been extensively studied for off-line planning, no framework for interleaving it with execution has been ever devised. In this paper, we extend planning via symbolic model checking with the ability of interleaving planning and execution in the case of nondeterministic domains and partial observability, one of the most challenging and complex planning problems. We build

Fibre-reinforced polymer (FRP) composite laminates have absence of fibre reinforcements in their thickness direction. This means their through thickness stiffness, strength and toughness are weak, relative to their in-plane properties. In multi-directional FRP laminates, first failures in the form of cracks tend to initiate and propagate between the plies of different fibre orientations. This type of cracking is commonly known as delamination, which can be considered a critical weakness of FRP composites. The resistance to delamination can be improved by introducing some form of composite toughening to improve the interlaminar fracture toughness of the material. These toughening concepts can be introduced in the form of intrinsic or extrinsic toughening.

Interesting algebraic and geometric results can be obtained by interleaving integer sequences term by term. To introduce this we consider how a well-known sequence can be considered as being composed of subsequences.The standard Fibonacci sequence (Fk):1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ... (1)is defined by the recurrence relation Fk = Fk - 1 + Fk - 2 for k ≥ 3 and F1 = F2 = 1.
