This paper describes our participation in blog track of TREC2009. All runs are submitted for both two task, namely Top stories identification task and faceted blog distillation task. The “FirteX” platform was used to index and retrieval posts. As for top stories identification task, to identify important headlines, we measure the importance of headline by accumulating the BM25 relevance score w...

It is important to adjust the welding gun's inclination during automatic curved-joint tracking of arc welding. In this paper, a novel method is proposed to detect the deviation and inclination of the welding gun based on the arc currents acquired by a high-speed rotational arc sensor. It uses a least-squares method to fit the arc currents to a plane in three dimensions. The deviation and inclin...

Exoplanets which are detected using the radial velocity technique have a well-known ambiguity of their true mass, caused by the unknown inclination of the planetary orbit with respect to the plane of the sky. Constraints on the inclination are aided by astrometric follow-up in rare cases or, in ideal situations, through subsequent detection of a planetary transit. As the predicted inclination d...

HYPOTHESIS Supraspinatus deficiency associated with total shoulder arthroplasty (TSA) provokes eccentric loading and may induce loosening of the glenoid component. A downward inclination of the glenoid component has been proposed to balance supraspinatus deficiency. METHODS This hypothesis was assessed by a numeric musculoskeletal model of the glenohumeral joint during active abduction. Three...

In an inertial sensor-based pedestrian navigation system, the position is estimated by double integrating external acceleration. A new algorithm is proposed to reduce z axis position (height) error. When a foot is on the ground, a foot angle is estimated using accelerometer output. Using a foot angle, the inclination angle of a road is estimated. Using this road inclination angle, height differ...

The movement of the mesiolingual cusp of the maxillary left first molar was studied in the frontal and horizontal planes. The movement was studied while varying the top wall, rear wall, and incisal guidance on the articulator. It can be concluded that the top wall inclination may significantly influence movement of the mesisolingual cusp of the maxillary first molar during working mandibular mo...

The orientation of an acetabulum or an acetabular prosthesis may be described by its inclination and anteversion. Orientation can be assessed anatomically, radiographically, and by direct observation at operation. The angles of inclination and anteversion determined by these three methods differ because they have different spatial arrangements. There are therefore three distinct definitions of ...

We present some modifications of the Hoede-Bakker index defined in a social network in which players may influence each other. Due to influences of the other actors, the final decision of a player may be different from his original inclination. The modifications presented in the paper are defined for an arbitrary probability distribution over all inclination vectors. In particular, they concern...

An important issue in zigzag pocket machining is to design a machining strategy such that the resulting tool path requires a minimum number of tool retraction motions. The minimization is further classified as either local or global. In a local minimization, the inclination of a zigzag path is given a priori, and the goal is to partition the planar region to be machined into a minimum number of...

The aim of the study was to estimate the influence of trunk inclination on muscle activity during sitting on forward inclined seats without backrest. The group consisting of thirteen healthy women was examined. Based on anthropometrical data two types of sitting position were adopted with two different angles between thighs and trunk: 120 and 135 degrees. Bioelectrical activity of five muscles ...
