In this paper we show how to calibrate a camera, mounted on a robot, with respect to the intrinsic camera parameters when the so-called hand-eye transformation between the robot hand and the camera is unknown. The calibration is based directly on the spatial and temporal derivatives in an image sequence and do not need any matching and tracking of features or a reference object. The calibration is

In the search for new pharmaceutically active compounds, it is recognized that Nature produces structurally different compounds in a great variety. By having the compounds or extracts tested in defined systems, new drugs or more often leads (a compound that has an interesting but moderate activity) can be found. When a lead is found, structurally similar compounds with modified functional groups a

Radionuclide imaging of cardiac function represents a number of well-validated techniques for accurate determination of right (RV) and left ventricular (LV) ejection fraction (EF) and LV volumes. These first European guidelines give recommendations for how and when to use first-pass and equilibrium radionuclide ventriculography, gated myocardial perfusion scintigraphy, gated PET, and studies with

Abstract in UndeterminedFor assembly tasks, the knowledge of both trajectory and forces are usually required. Consequently, we may use kinesthetics or teleoperation for recording human demonstrations. In order to have a more natural interaction, the operator has to be provided with a sense of touch. We propose a bilateral teleoperation system which is customized for this purpose. We introduce diff

We show that the problem of constructing a minimum directed Steiner tree of depth O(log(d)n) in a directed graph of maximum outdegree d admits an expO(root logn)-approximation in polynomial time.

This paper considers a housing market with price restrictions. On such markets, the existence of a unique minimum rationing equilibrium price vector has been established for each preference profile on a general preference domain that contains almost all preference profiles. This vector can be used as a key ingredient in a direct and strategy-proof allocation mechanism. The main contribution of thi

This paper presents a state-of-the-art analysis of current systems for product identification utilized within the Swedish sector of construction and facility management. The study also discusses the concept of object and class identification in information systems development. The purpose of the study is to identify and define concepts in a common information structure that provides a framework fo

Product alternatives suggested by a generative design system often need to be evaluated on qualitative criteria. This evaluation necessitates that several feasible solutions which fulfill all technical constraints can be proposed to the user of the system. Also, as concept development is an iterative process, it is important that these solutions are generated quickly; i.e., the system must have a

We investigate the out-of-sequence measurements particle filtering problem for a set of conditionally linear Gaussian state-space models, known as mixed linear/nonlinear state-space models. Two different algorithms are proposed, which both exploit the conditionally linear substructure. The first approach is based on storing only a subset of the particles and their weights, which implies low memory

Resultaten tyder på att geoelektriska undersökningar kan användas för att lokalisera rester av murar och bastioner i den aktuella miljön. Resistivitetsresultaten är därvid mest användbara, medan IP-resultaten ger kompletterande information i område 2. Resultaten från område 1 är komplexa, troligen p.g.a. rester av yngre byggander och verksamheter i området, men en möjlig tolkning är att de högresi
