This paper provides an overview of the work done at the Centrum Wiskunde & Informatica (CWI) and Delft University of Technology (TU Delft) for different tracks of TREC 2013. We participated in the Contextual Suggestion Track, the Federated Web Search Track, the Knowledge Base Acceleration (KBA) Track, and the Web Ad-hoc Track. In the Contextual Suggestion track, we focused on filtering the enti...
Key track-level performance metrics for our fusion algorithm include the probability of correct track-to-track association and track fragmentation. We study the performance of the algorithm with simulated single-sensor tracks, for two scenarios of interest. The first scenario is based on a data collection for a set of 30 GPS-equipped targets, while the second is based on simulated ground truth ...
background: radon is an odourless, colourless and tasteless gas and it is the first cause of lung cancer among non- smokers. the assessment of the level of radium in building materials helps in understanding the radiological implications. it has been observed that everyone has some levels of exposure to them. therefore measurement of radium and radon in the soil samples are important from publi...
background: the fatal effect of ionizing radiation on cells depends on linear energy transfer (let) level. the distribution of ionizing radiation is sparse and homogeneous for low let radiations such as x or γ, but it is dense and concentrated for high let radiation such as heavy-ions radiation. material and methods: chinese hamster ovary cells (cho-k1) were exposed to 4 gy fe-ion 2000 kev/m. ...
the evaluation and control of the trains induced vibrations needs even more attention in the case of underground tracks which passes near to monuments and historical sites. the rail corrugations which occur due to the wheels’ impulse loads during the operation period of underground railway tracks, usually amplify the ground borne noise and vibration. in the current study, the mentioned phenomen...
in this paper, we propose a novel method for fully automatic detection and tracking of human heads and faces in video sequences. the proposed algorithm consists of two modules: a face detection module and a face tracking module. the detection module, detects the face region and approximates it with an ellipse at the first frame using a modified version of adaboost cascaded classifier. the detec...
BACKGROUND AND PURPOSE When fractionation schemes for hypofractionation and stereotactic body radiotherapy are considered, a reliable cell survival model at high dose is needed for calculating doses of similar biological effectiveness. An alternative to the LQ-model is the track-event theory which is based on the probabilities for one- and two two-track events. A one-track-event (OTE) is always...
The geometry of a ballasted railway gradually deteriorates with trafficking, mainly as result the plastic settlement track-bed (ballast and sub-base). rate amount depend on number factors, for various reasons are difficult to predict or estimate analytically. As result, empirical equations estimating development track train passage have been proposed. A review these shows that they (i) do not r...
