The RAS, “Robot Antartico di Superficie”, is intended to operate in a hostile and generally unknown environment, where the ability of sensing obstacles or special features (crevasses, sastrugi, composition of the soil) can represent the key point to successfully perform the required mission or to fail: wind storms (and many other atmospheric phenomena giving rise to white out) can make useless ...

This article presents a novel autonomous system concept for automated construction of houses and other buildings via deposition of concrete and similar materials. The overall system consists of a novel cable-suspended mobility subsystem (a self-contained extension of the RoboCrane), a deposition nozzle subsystem, a metrology subsystem, and a material supply subsystem. This article focuses mainl...

I various industries end-product manufacturers acquire core subsystems from upstream technology provider firms and focus primarily on efficient end-product integration. We examine the strategic interactions between a technology firm that introduces a new subsystem and the respective end-product manufacturers (“integrators”). We analyze how the fraction of end-product functionalities prepackaged...

In this paper, a hybrid system was proposed for chemical entity mention recognition (CEMP) and gene/protein related object recognition (GPRO) in BeCalm challenge. Firstly, five individual machine learning-based subsystems were developed to identify chemical and gene/protein related entity mentions, that is, a bidirectional LSTM (long-short term memory, a variant of recurrent neural network)-bas...

In this paper, we enumerate the (nonisomorphic) Steiner triple systems of order 19 which contain a subsystem of order 9. The number of these designs is precisely 284457. We also determine which of these designs also contain at least one subsystem of order 7, and how many. Exactly 13529 of them contain at least one subsystem of order 7.

This document describes an architecture for describing SNMP Management Frameworks. The architecture is designed to be modular to allow the evolution of the SNMP protocol standards over time. The major portions of the architecture are an SNMP engine containing a Message Processing Subsystem, a Security Subsystem and an Access Control Subsystem, and possibly multiple SNMP applications which provi...

The problem of controlling force and position of a exible link manipulator in contact with a compliant environment is considered in this paper. Using singular perturbation theory, a slow subsystem associated with rigid motion dynamics and a fast subsystem associated with link exible dynamics are identi ed. Hence a two-time scale control strategy is adopted, consisting in a force and position co...

Integrity constraints form an important part of a data model. Therefore, a complete integrity constraint handling subsystem is considered an important part of any modern DBMS. In implementing an integrity constraint handling subsystem, there are two major problem areas: providing enough functionality and delivering good performance in constraint enforcement. In the PRISMA project, an integrity ...

Connection tracking subsystem on Linux tracks states of network flows. It is utilized by packet filter for stateful filtering. In this paper, we propose solutions to issues that arise where connection tracking subsystem handles Routing Header and Mobile IPv6. We also describe how the current connection tracking subsystem handles IPv6 fragments without disturbing Path MTU discovery. As a result ...

A new gluing algorithm is presented that can be used to couple distributed subsystem models for dynamics simulation of mechanical systems. Using this gluing algorithm, subsystem models can be analyzed at their distributed locations, using their own independent solvers, and on their own platforms. The gluing algorithm developed relies only on information available at the subsystem interfaces. Th...
