Remote management is essential for wireless sensor networks (WSNs) designed to run perpetually using harvested energy. A natural division of function for managing WSNs is to employ both an in-band data plane to sense, store, process, and forward data, and an out-of-band management plane to remotely control each node and its sensors. This paper presents SRCP, a Simple Remote Control Protocol tha...

The title compound, C(18)H(24)I(2), has an adamantanoid structure with tetra-hedral cages having four C atoms lying on the same plane [(I-)C-C-C-C(-I) torsion angle = 0°]. The plane is extended by the two I atoms, each having a deviation of 1.0 (6) Å [C-C-C-I torsion angle = 178.9 (4)°]. The central C-C bond connecting the two quaternary carbons seems enlarged [1.593 (9) Å] in comparison to the...

We consider two types of folding applied to equilateral plane graph linkages. First, under continuous folding motions, we show how to reconfigure any linear equilateral tree (lying on a line) into a canonical configuration. By contrast, such reconfiguration is known to be impossible for linear (nonequilateral) trees and for (nonlinear) equilateral trees. Second, under instantaneous folding moti...

Modern network interfaces demand highly intelligent traffic management in addition to the basic requirement of wire speed packet forwarding. Several vendors are releasing network processors in order to handle these demands. Network workloads can be classified into data plane and control plane workloads, however most network processors are optimized for data plane. Also, existing benchmark suite...

Quality of service (QoS) provisioning for dynamically composable software elements in a programmable router has not received much attention. We present a router platform that supports extensible and configurable routing elements, and provides them with access to given resource allocations. Scheduling issues for these elements are discussed: (1) flow-based scheduling, (2) the preemptibility of a...

Springer 2 This book is a companion to our book [DeDu08], which considered the notions of polycycles, face-regularity and weak face-regularity of plane graphs and toroidal maps. The central actors in the present monograph are the zigzags and central-circuits of 3-or 4-regular plane graphs, which allow to obtain a double covering or covering of the edge-set. This study is mainly focused on speci...

Generic camera odometry can be performed using two images of the same plane, such as the ground plane even in the case of non central cameras. It is possible to recover both the angle and rotation center describing a generic planar motion on the ground plane if the center is visible in both images. We present an algorithm to recover these two parameters from an initial set of correspondences an...

OBJECTIVE A modified transsphenoidal technique to remove huge pituitary adenomas with marked suprasellar extension (4.5-8 cm of maximum diameter) is presented. METHODS The technique allowed to avoid the occurrence of a precocious descent of the suprasellar cisternal plane into the sellar plane during tumour removal and its related consequences (incomplete tumour removal, occurrence of cerebro...

In the structure of the title compound, C(27)H(39)N(3)O(3), each of the (4-oxopiperidin-1-yl)methyl residues adopts a flattened chair conformation (with the N and carbonyl groups being oriented to either side of the central C(4) plane) and they occupy positions approximately orthogonal to the central benzene ring [C(benzene)-C-C(methyl-ene)-N torsion angles 103.4 (2), -104.4 (3) and 71.9 (3)°];...
