Self-compacting concrete can be defined as the concrete which requires no vibrations and can flow around obstructions, encloses the reinforcement and fills up the formwork completely under its self weight. Over the last ten years, significant amount of work has been carried out on self-compacting concrete all over the world. In countries like Japan, Sweden, Thailand, UK etc., the knowledge of S...

In this paper we investigate the possibility of a dynamical definition of an effective temperature for compacting granular media in the framework of the fluctuation-dissipation (FD) relations. We have studied two paradigmatic models for the compaction of granular media, which consider particles diffusing on a lattice, with either geometrical (tetris model) or dynamical (Kob-Andersen model) cons...

Experiences in the development of Ultra High Performance Concrete found a very high flowability in concrete with low water powder ratio. Because of the high viscosity of the cement paste, compaction was necessary. To improve the compaction characteristics of the concrete the idea of adding coarse aggregate was developed. The first tests showed a good workability of the fresh concrete and a good...

We investigate some conditions for data to be discarded, independently of the chosen concept learning algorithm or concept representation language. Then an algorithm for discarding data is presented in the framework of Iterative Versionspaces, which is a depth-first algorithm computing versionspaces as introduced by Mitchell. We update the datastructures used in the Iterative Versionspaces algo...

In today's fast-growing world, it is critical to utilize green, sustainable, and resilient materials keeping the impact of carbon in mind. The use Nanomaterials has evolved improve performance characteristics cement composites. As a result, Graphene Oxide (G.O) was discovered be one with an exceptional variety potential strength toughness cement-based Nano-material concrete new kind composed Na...

In this paper we present results of structural studies of compacting experimental systems of ductile grains in two and three dimensions. The high precision of our two-dimensional experiments enables a detailed study of the evolution of coordination numbers and local crystalline arrangements as a function of the packing fraction. The structure in both dimensions deviates considerably from that o...

A unidirectional heap is a heap where all pointers go in one direction, e.g. from newer to older objects. For a strict functional language, such as Erlang, the heap may be arranged so that it is unidirectional. We here present a compacting garbage collection algorithm which utilizes the fact that a heap is unidirectional. Only one memory space is used in our algorithm. In fact, no extra memory ...

Testing is one of the biggest problems of the software industry. Coverage is the main technique for showing that the testing has been thorough. Coverage can be used to find a good regression-suite, i.e. a set of tests that is run on the application after software or data changes in order to check that no new bugs were introduced. This paper is about the experience gained in IBM Haifa Research L...

By utilising the fact that all data in the heap in an Erlang implementation may be arranged so that all pointers go towards earlier allocated objects, a compacting garbage collection algorithm has been designed. In contrast to a copying garbage collection algorithm, only one memory space is used. In fact, no extra memory is used at all, not even any reserved bits within the cells. The algorithm...

The translocation of single-stranded DNA (ssDNA) across membranes of two cells is a fundamental biological process occurring in both bacterial conjugation and Agrobacterium pathogenesis. Whereas bacterial conjugation spreads antibiotic resistance, Agrobacterium facilitates efficient interkingdom transfer of ssDNA from its cytoplasm to the host plant cell nucleus. These processes rely on the Typ...
