In the last decade, significant progress has been made on developing automatic farfield tracking systems. The PETS 2007 dataset provides some interesting event detection challenges. In this paper, we describe a method of bootstrapping a background model in the presence of significant lighting changes. We then use a blob tracker as an attention mechanism for finding tracks of interest, which we ...

This paper presents a hybrid dialog state tracker that combines a rule based and a machine learning based approach to belief state tracking. Therefore, we call it a hybrid tracker. The machine learning in our tracker is realized by a Long Short Term Memory (LSTM) network. To our knowledge, our hybrid tracker sets a new state-of-the-art result for the Dialog State Tracking Challenge (DSTC) 2 dat...

The CMS Silicon Strip Tracker, referred from here on as the Tracker, was commissioned using cosmic muons in two main setups: the Magnet Test Cosmic Challenge (MTCC) and the Tracker Integration Facility (TIF). A large number of studies of the tracker performance and offline data analysis has been performed and many others are still ongoing. Only few of these studies for both setups are presented...

In this paper our focus is to study certain covering properties in topological spaces by using semi-open covers. A part of this article deals with Rothberger-type covering properties. The notions of s-Rothberger, almost s-Rothberger, star s-Rothberger, almost star s-Rothberger, strongly star s-Rothberger spaces are defined and corresponding properties are investigated.

STAR is a large acceptance spectrometer capable of precision measurements of a wide variety of strange particles. We discuss the STAR detector, its configuration during the first two years of RHIC operation, and its initial performance for Au+Au collisions. The expected performance for strangeness physics and initial data on strange particle reconstruction in Au+Au collisions are presented. The...

Tracking multiple objects in surveillance scenarios face considerable difficulty in handling occlusions. We report a composite tracker based on feature tracking and colour based tracking that demonstrates superior performance under high degrees of occlusion. Disjoint foreground blobs are extracted by using change masks obtained by combining an online-updated background model and flow informatio...

The main subsystems of the CMS Tracker have been assembled together in a dedicated large clean room at CERN, prior to the installation in CMS. Following the integration of the Tracker a long commissioning period took place, during which, up to 15% of the silicon modules were operated and read out simultaneously at different temperatures. Some of the achievements of this commissioning phase are ...

Let $D$ be an integral domain and $star$ a semistar operation stable and of finite type on it. We define the semistar dimension (inequality) formula and discover their relations with $star$-universally catenarian domains and $star$-stably strong S-domains. As an application, we give new characterizations of $star$-quasi-Pr"{u}fer domains and UM$t$ domains in terms of dimension inequal...

Der Kanade-Lucas-Tomasi (KLT) Tracker ist ein etabliertes Verfahren zur Bewegungsanalyse bzw. Bewegungskorrektur einer Kamera auf Oberflächen. Derartige Systeme, die auf dem KLT Tracker beruhen, finden vermehrt auch in medizintechnischen Szenarien ihren Einsatz. So ist die Frage wichtig, ob diese Methode auch auf relativ kontrastarmen Oberflächen wie menschlichem Gewebe, und hier insbesondere K...

background: anti-angiogenic therapy is a crucial step in cancer treatment. the discovery of new anti-angiogenic compounds from marine organisms has become an attractive concept in anti-cancer therapy. because little data correlated to the pro- and anti-angiogenic efficacies of ophiuroidea, which include brittle star, the current study was designed to explore the anti-angiogenic potential of bri...
