An essential requirement for providing secure services in wireless sensor networks is the ability to establish pairwise keys among sensors. Due to resource constraints on the sensors, the key establishment scheme should not create significant overhead. To date, several key establishment schemes have been proposed. Some of these have appropriate connectivity and resistance against key exposure, ...

Preface This report provides a detailed documentation on the application of static program analysis to the key establishment protocols of the ZigBee wireless sensor network standard. The approach presented in this report is within the scope of the SENSORIA (Software Engineering for Service-Oriented Overlay Computers) project, and will form a preliminary version of one of the chapters in my PhD ...

This paper shows that plants located in areas where an industry concentrates are larger, on average, than plants in the same industry outside such areas. In some sectors, such as manufacturing, the differences are substantial. The connection between size and concentration is stronger than what we would expect to Ž nd if plants were randomly distributed like darts on a dartboard.

At least two control points must be available in order to determine the position and orientation of a total station (TS). This paper analyses optimum horizontal location of TS with respect to the control points and gives an answer to question “What is the best location of total station with respect to the control points if the goal is to determine the coordinates of TS and detail points as prec...

So this small package arrives at my office, addressed to “Anniken Goldstein.” Two Goldsteins work in my office, my Bride/Empress and myself, so she took the liberty of opening it up, and extracting a Darth Vader head coffee cup from a carefully bundled straw package. There was no accompanying note; the return address indicated that none was needed. Everyone from my receptionist to my office man...

In this paper we describe an approach to the modelling of virtual enterprise agreements. An important and ever-present issue in the set-up phase of such a virtual enterprise is the virtual enterprise contract. As one of the goals of virtual enterprises is to become operational quickly, the time consumed by the set-up phase must be reduced to a minimum. At the same time it has to be guaranteed t...

Food-service establishments that use on-site wastewater treatment systems are experiencing pretreatment system and/or drain field hydraulic and/or organic overloading. This study included characterization of four wastewater parameters (five-day biochemical oxygen demand [BOD5]; total suspended solids [TSS]; food, oil, and grease [FOG]; and flow) from 28 restaurants located in Texas during June,...

Establishing grasslands has important implications for wildlife, especially in areas historically rich in grasslands that have since been converted to row crop agriculture. Most grasslands established under farm conservation programs have replaced annual crops with perennial cover that provides year-round resources for wildlife. This change in land use has had a huge influence on grassland bird...

The process of sister chromatid pairing, or cohesion establishment, is coupled to DNA replication and fundamental to proper chromosome segregation and cell viability. In the past year, several articles have provided important new insights into cohesion establishment, an activity predicated on the acetyltransferase Ctf7/Eco1. Here, I review new findings that the conversion of chromatid-bound coh...

Timing of cell division is coordinated by the Septation Initiation Network (SIN) in fission yeast. SIN activation is initiated at the two spindle pole bodies (SPB) of the cell in metaphase, but only one of these SPBs contains an active SIN in anaphase, while SIN is inactivated in the other by the Cdc16-Byr4 GAP complex. Most of the factors that are needed for such asymmetry establishment have b...
