Various methods are presented to control the attitude of satellite due to lack of information of yaw axis attitude so far. In this paper, a new method is used which is more general and is applicable to all types of satellites, with at least one controller. This method is not limited to YAW axis and can control the two other axes as well. One feature of this approach is the ability to be modi...

As the number of systems which offer annotations on digital documents increases, robust anchoring of annotations is a key challenge. It is especially important if the annotator lacks write-access to the document being annotated. For example, if someone makes an annotation on a web page today and the web page changes tomorrow, what happens to the annotation? One approach is simply to “orphan” th...

In this paper, we study sensor fusion for the attitude stabilization of Micro Aerial Vehicles (MAVs), in particular mechanical flying insects. Following a geometric approach, a dynamic observer is proposed which estimates attitude based on kinematic data available from different and redundant bio-inspired sensors such as halteres, ocelli, gravitometers, magnetic compass and light polarization c...

introduction: dental students are high risks persons in exposing to hepatitis b infection. dental students knowledge and attitude about hepatitis b infection is necessary for assessment the educational evaluation and supervision of dental treatments. the aim was to survey the knowledge and attitude in the final year students of dental schools in tehran regarding hepatitis b infection control an...

Discussion is frequently observed in democratic politics, but change in view is rarely observed. Call this the ‘unchanging minds hypothesis’. I assume that a given belief or desire is not isolated, but, rather, is located in a network structure of attitudes, such that persuasion sufficient to change an attitude in isolation is not sufficient to change the attitude as supported by its network. T...

While on-line shopping is considered as a special type of e-service, the adoption rate of this service in Taiwan has been paid attention recently. The initial adoption of on-line shopping is the important driving force to further influence the use and continued use of this service. The model of Trust and technology acceptance model (TAM) in Gefen et al. [1] has been well studied in on-line shop...

Methods for measuring or estimating ground shape by a laser range finder and a vision sensor (Exteroceptive sensors) have critical weaknesses in terms that these methods need a prior database built to distinguish acquired data as unique surface conditions for driving. Also, ground information by Exteroceptive sensors does not reflect the deflection of ground surface caused by the movement of UG...
