In the basement of the house is a fuse box, where the main electricity supply is distributed over ten separately fused groups. Each fuse protects a number of the—more than fifty— power outlets in and around the house. For reasons that need not concern us here, the mapping from outlet to fuse group is rather haphazard. Unfortunately, the previous owner had lost the group chart that lists for eve...

Neisseria gonorrhoeae is an obligate pathogen that hijacks iron from the human iron transport protein, holo-transferrin (Fe(2)-Tf), by expressing TonB-dependent outer membrane receptor proteins, TbpA and TbpB. Homologous to other TonB-dependent outer membrane transporters, TbpA is thought to consist of a β-barrel with an N-terminal plug domain. Previous reports by our laboratories show that the...

In der Anwendungsentwicklung kommen zunehmend Plug-in-basierte Ansätze zum Einsatz. Die Verwendung Plug-in-basierter Techniken hat Auswirkungen auf die Entwicklung der Software, in der die spezifischen Eigenschaften von Plug-ins berücksichtigt werden müssen. Dieser Beitrag identifiziert basierend auf Erfahrungen aus der Praxis Entwurfsfragen, die sich beim Einsatz von Plug-ins stellen, und disk...

We have previously reported on the development of explosively formed fuse (EFF) opening switches for use in applications where very long conduction times (lO's or lOG's p.s) are required and where opening times of 1-10 p.s are adequate. In this paper we report on the development of an EFF that allows magnetic flux in the switch to be delivered to the load rather than lost from the circuit. The ...

We show that depending on the disorder, a small noise added to the threshold distribution of the fuse network may or may not completely change the subsequent breakdown process. When the threshold distribution has a lower cutoff at a finite value and a power law dependence towards large thresholds with an exponent which is less than 0.16 ± 0.03, the network is not sensitive to the added noise, o...

Many systems are partially stochastic in nature. We have derived datadriven approaches for extracting stochastic state machines (Markov models) directly from observed data. This chapter provides an overview of our approach with numerous practical applications. We have used this approach for inferring shipping patterns, exploiting computer system side-channel information, and detecting botnet ac...

In this paper, we propose a scheme for 3D model construction by fusing heterogeneous sensor data. The proposed scheme is intended for use in an environment where multiple, heterogeneous sensors operate asynchronously. Surface depth, orientation, and curvature measurements obtained from multiple sensors and vantage points are incorporated to construct a computer description of the imaged object....

edge detection and edge enhancement techniques play an essential role in interpreting potential field data. this paper describes the application of various edge detection techniques to gravity data in order to delineate the edges of subsurface structures. the edge detection methods comprise analytic signal, total horizontal derivative (thdr), theta angle, tilt angle, hyperbolic of tilt angle (h...
