Presently, the MAD Automatic Differentiation package for matlab comprises an overloaded implementation of forward mode AD via the fmad class. A key design feature of the fmad class is a separation of the storage and manipulation of directional derivatives into a separate derivvec class. Within the derivvec class, directional derivatives are stored as matrices (2-D arrays) allowing for the use o...
Naturally spun silks generate fibres with unique properties, including strength, elasticity and biocompatibility. Here we describe a microfluidics-based strategy to spin liquid native silk, obtained directly from the silk gland of Bombyx mori silkworms, into micron-scale capsules with controllable geometry and variable levels of intermolecular β-sheet content in their protein shells. We demonst...
Non-Volatile RAM (NVRAM) is a novel class of hardware technology which is an interesting blend of two storage paradigms: byte-addressable DRAM and block-addressable storage (e.g. HDD/SSD). Most of the existing enterprise relational data management systems such as SAP HANA have their internal architecture based on the inherent assumption that memory is volatile and base their persistence on expl...
Energy consumption has become a first-class optimization goal in design and implementation of data-intensive computing systems. This is partic‐ ularly true in the design of database management system (DBMS), which was found to be the major consumer of energy in the software stack of modern data centers. Among all database components, the storage system is the most powerhungry element. In this p...
XML has gained prominence as data storage and exchange format for web applications. This is because there are certain features which are unique to XML like self descriptivism, extensibility and non proprietary text document storage. In spite of all these unique features XML has an inherent limitation of verbosity. This size problem of XML should be dealt with efficiently so that a good compress...
Power dissipation by storage systems in mobile computers accounts for a large percentage of the power consumed by the entire system. Reducing the power used by the storage device is crucial for reducing overall power consumption. A new class of secondary storage devices based on microelectromechanical systems (MEMS) promises to consume an order of magnitude less power with 10–20 times shorter l...
Hydrogen has a very diverse chemistry and reacts with most other elements to form compounds, which have fascinating structures, compositions and properties. Complex metal hydrides are a rapidly expanding class of materials, approaching multi-functionality, in particular within the energy storage field. This review illustrates that complex metal hydrides may store hydrogen in the solid state, ac...
This paper derives exact expressions for the Laplace-Stieltjes transform of order picking time in single- and 2-block warehouses. We consider manual warehouses that deploy return routing assume sizes follow a Poisson distribution. The results this apply to wide range storage policies, including but not restricted class-based random storage. Furthermore, we compare performance policies warehouse...
