Maximizing the battery lifetime of wireless sensor nodes and equipping them with elliptic curve cryptography is a challenge that requires new energy-saving architectures. In this paper, we present an architecture that drops a hardware accelerator between CPU and RAM. Thus neither the CPU nor the data memory need to be modified. In a detailed comparison with a software-only and a dedicated hardw...

In large wireless sensor networks, the few nodes close to the monitoring station are likely to prove the bottleneck in the useful lifetime of the network. We examine a strategy of equipping these nodes with a larger share of the total initial energy (battery) than the others, and generalizing this notion to the rest of the network. We solve a design problem involving optimizing the network life...

We describe the design of Grey, a set of software extensions that convert an off-the-shelf smartphone-class device into a tool by which its owner exercises and delegates her authority to both physical and virtual resources. We focus on the software components and user interfaces of Grey, highlighting the features of each. We also discuss an initial case study for Grey, in which we are equipping...

A large section of the report is devoted to a discussion of the kinds of preparation necessary for equipping individuals to fulfill these diverse functions. Many of the weaknesses in the stmcture of nursing education today, which impede progress toward this goal, are exposed, and constructive recommendations are made for their improvement. This report is based on data collected systematically f...

Actin networks in certain single-celled organisms exhibit a complex pattern-forming dynamics that starts with the appearance of static spots of actin on the cell cortex. Spots soon become mobile, executing persistent random walks, and eventually give rise to traveling waves of actin. Here we describe a possible physical mechanism for this distinctive set of dynamic transformations, by equipping...

A multiplicative Schwarz overlapping domain decomposition method is considered for solving elliptic boundary value problems. By equipping the relevant Sobolev spaces on the subdomains with wavelet bases, adaptive wavelet methods are used for approximately solving the subdomain problems. The union of the wavelet bases forms a frame for the Sobolev space on the domain as a whole. The resulting me...

For the past decade, robotics has mostly focused on low-level sensing and control tasks such as sensor fusion, path planning, and manipulator design and control. At the same time the field of Cognitive Robotics made significant progress in equipping robots and software agents with high-level cognitive functions such as reasoning over actions, goals, and environments, as well as behaviour planni...

Equipping the probability space with a local Dirichlet form with square field operator Γ and generator A allows to improve Monte Carlo computations of expectations, densities, and conditional expectations, as soon as we are able to simulate a random variable X together with Γ[X] and A[X]. We give examples on the Wiener space, on the Poisson space and on the Monte Carlo space. When X is real-val...

Goal – The goal of the proposed intervention is to improve efficiency and quality of care by equipping physicians to make effective resource management decisions when ordering diagnostic tests. The intervention harnesses the power of Electronic Medical Records (EMR) to provide physicians with data on the costs of diagnostic tests at their fingertips, as they enter orders in real time. With effe...
