EVAL is a widely used yet frequently misunderstood SAS macro language function due to its seemingly simple form. However, when its actual argument is a complex macro expression interlaced with special characters, mixed arithmetic and logical operators, or macro quotation functions, its usage and result become elusive and problematic. In this paper, we aim to explore and demystify the intricate ...

For the characterization of the 10 mA ion beam delivered by the new High Current Linac at GSI, sophisticated , mainly non-intersepting diagnostic devices were developed. Besides the general setup of a versatile test bench, we discuss in particular bunch shape and emittance measurements. A direct time-of-flight technique with a diamond particle detector is used to observe the micro-bunch distrib...

Asatisfactory pace of economic growth in any economy is contingent upon availability of adequate capital. A well-developed securities market, while acting as a provider of funding for economic activity at the macro level, plays specific roles in an economy: it diffuses stress on the banking sector by diversifying credit risk across the economy, supplies funds for long-term investment needs of t...

We analyze the use of built-in policies, or macro-actions, as a form of domain knowledge that can improve the speed and scaling of reinforcement learning algorithms. Such macro-actions are often used in robotics, and macro-operators are also well-known as an aid to state-space search in AI systems. The macro-actions we consider are closed-loop policies with termination conditions. The macro-act...

in this paper, a novel technique on friction aided deep drawing using tapered blank holder divided into eight segments is proposed to overcome defect of friction aided deep drawing using four segments tapered blank holder technique. a taper blank holder is designed to be of two parts: stationary part with 5 degree taper angle and moving parts divided into eight tapered segments. the main functi...

The MSC macro package facilitates LaTEX users to easily include Message Sequence Charts in their texts. This article describes the motivation for developing the MSC macro package, the features of the MSC macro package, and the design of the MSC macro package.

Enhanced Inter Cell Interference Coordination (eICIC) for co-channel deployments of pico cells throughout a macro cell layout is studied. In particular, we analyze a scenario where only some macro cells have picos deployed, while other macro cells have no small cells. The challenge for such highly irregular scenarios is how to operate eICIC, and especially how to coordinate macro-cell muting. O...

The importance of production systems in artificial intelligence has been repeatedly demonstrated by a number of expert systems. Much effort has therefore been expended on finding an efficient processing mechanism to process production systems. While data-flow principles of execution offer the promise of high programmability for numerical computations, we study here variable resolution actors, c...
