MalStone: Towards A Benchmark for Analytics on Large Data Clouds

Developing data mining algorithms that are suitable for cloud computing platforms is currently an active area of research, as is developing cloud computing platforms appropriate for data mining. Currently, the most common benchmark for cloud computing is the Terasort (and related) benchmarks. Although the Terasort Benchmark is quite useful, it was not designed for data mining per se. In this paper, we introduce a benchmark called MalStone that is specifically designed to measure the performance of cloud computing middleware that supports the type of data intensive computing common when building data mining models. We also introduce MalGen, which is a utility for generating data on clouds that can be used with MalStone

Operation of the CDF silicon vertex detector with colliding beams at Fermilab

In this paper we briefly describe the main features of the CDF Silicon Vertex Detector (SVX) and discuss its performance during actual colliding beam operation at the Fermilab Tevatron. Details on S/N ratio, alignment, resolution, and efficiency are given.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/87708/2/1908_1.pd

Measurement of the Top Quark mass at CDF

We report the measurement of the Top Quark using complete kinematic reconstruction of events with a W and 4 jets. Included in this talk are a brief description of the technique, the observed results when applied to events before and after requiring a b‐tagged jet, and discussion of systematic aspects of the measurement. We additionally present results which indicate the presence of a second W in the events of decaying to two jets. © 1996 American Institute of Physics.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/87315/2/272_1.pd

A Service Oriented Architecture Supporting Data Interoperability for Payments Card Processing Systems

Abstract. As the size of an organization grows, so does the tension between a centralized system for the management of data, metadata, derived data, and business intelligence and a distributed system. With a centralized system, it is easier to maintain the consistency, accuracy, and timeliness of data. On the other hand with a distributed system, different units and divisions can more easily customize systems and more quickly introduce new products and services. By data interoperability, we mean the ability of a distributed organization to work with distributed data consistently, accurately and in a timely fashion. In this paper, we introduce a service oriented approach to analytics and describe how this is used to measure and to monitor data interoperability

Top Quark Physics: Future Measurements

We discuss the study of the top quark at future experiments and machines. Top’s large mass makes it a unique probe of physics at the natural electroweak scale. We emphasize measurements of the top quark’s mass, width, and couplings, as well as searches for rare or nonstandard decays, and discuss the complementary roles played by hadron and lepton colliders.
