In conventional power plants trash-racks are provided at the intakes to protect the turbines. In pumped storage plants, the draft tube or tailrace must also have trash-racks to protect the units while pumping. Because the loads believed to cause many failures of trash-racks are dynamic in nature, it is important to understand the dynamic characteristics of trash-rack structures in general and a...

This paper presents a general analysis on the shear stiffness of spine bracing systems of selective storage racks in the down-aisle direction. Unlike the architectural steel structure, the bearing capacity of bracing connection in the spine bracing systems of steel rack structure is weaker than that of bracing members. Firstly, destructive tests of spine bracing connection in single entry racks...

The aim of this study was to identify in rat hepatocytes cellular polypeptides that bind protein kinase C (PKC) and may influence its activity and its compartmentation. At least seven proteins, with apparent M(r) values between 12,000 and 36,000, that behave like Receptors for Activated C-Kinase (RACKs) were found in the Triton-X-100-insoluble fraction of these cells; i.e. PKC bound to these po...

Often unbraced, the stability of steel storage racks may depend solely on the pallet beam to upright connector and on the stiffness of the base plate to floor connection ([1]). This paper presents experimental results from cyclic tests performed on portal beam to upright bolted moment connections intended for cold-formed steel drive-in and drive-through storage racks. In storage racks, portal b...

A rack, which is the algebraic distillation of two of the Reidemeister moves, is a set with a binary operation such that right multiplication is an automorphism. Any codimension two link has a fundamental rack which contains more information than the fundamental group. Racks provide an elegant and complete algebraic framework in which to study links and knots in 3{manifolds, and also for the 3{...

Modeling and analysis work was done on various supermarket refrigeration systems for their energy efficiency, TEWI (Total Equivalent Warming Impact), and annual operating cost. The systems which were modeled in detail include parallel racks, distributed, self-contained, glycol secondary loop, and CO2 secondary loop (medium temperature) and cascade (low temperature). Based on R404A modeling resu...

Data load balancing is one of the key problems of big data technology. As a big data application, Hadoop has had many successful applications. HDFS is Hadoop Distributed File System and has the load balancing procedure which can balance the storage load on each machine. However, this method cannot balance the overload rack preferentially, and so it is likely to cause the breakdown of overload m...

A rack on [n] can be thought of as a set of maps (fx)x∈[n], where each fx is a permutation of [n] such that f(x)fy = f −1 y fxfy for all x and y. In 2013, Blackburn showed that the number of isomorphism classes of racks on [n] is at least 2(1/4−o(1))n 2 and at most 2(c+o(1))n 2 , where c ≈ 1.557; in this paper we improve the upper bound to 2(1/4+o(1))n 2 , matching the lower bound. The proof in...

My research focuses on the intersection of computer systems, algorithmic game theory, and economic mechanism design. My interdisciplinary work has introduced computer architects to a rich body of knowledge in economics and game theory. My dissertation marks the beginning of a paradigm shift in computer architecture toward more robust, game-theoretic analysis of shared systems. As a result, my w...
