Beijing’s mountainous areas have an important ecological significance because they are ecological conservation and water source protection areas of Beijing. The impact of precipitation on the vegetation coverage of Beijing’s mountainous areas is qualitatively analyzed using multi-temporal Landsat images obtained during the last 20 years. Firstly, the influence of external factors, such as pheno...

We describe the locomotion dynamics of a biomimetic robot and compare them with those of its exemplar: the cockroach. The robot is a small (0.275kg) hexapod created using a layered manufacturing technique that allows us to tailor the compliance and damping of the limbs to achieve passive stabilization similar to that observed in insects. The robot runs at over 3 body-lengths per second (55 cm/s...

In this study, it is theorized that party websites play a distinctive role in two regards: (i) they function as a pluralistic civic forum by facilitating the voice of oppositional challengers and increasing the visibility of minor and fringe parties, so that attentive citizens can learn more about the range of electoral choices; (ii) in addition, party websites function as a channel for politic...

The construction of complex objects, such as an aircraft, requires the creation of a dedicated industrial system. By industrial system, we mean all the material and immaterial means used to build the object (labor, machines, factories, etc.). Classically, this means of production is defined after that the design of the product. In other words, the specifications of the product are the requireme...

springs are the  mechanical parts which have many application in industries. static and dynamic forces cause relaxation in these parts so that they lose some of their free length and reaction force. springs constant are very important in airplane and vailway industry since constant and variable forces are applied to them in period time, therefore it is necessary to avoid decreasing in spring co...

An experimental speech recognition system was developed for German using an already existing technology reported elsewhere (1). The system recognizes complete sentences when the words are spoken with a small pause in between. The user has to train the system in advance by uttering 110 short sentences. The size of the system's vocabulary is presently limited to about 1300 words, with a coverage ...

THE1974 ARTICLE BY Line and Sandison entitled “ ‘Obsolescence’ and Changes in the Use of Literature with Time” was highly critical of many assumptions about obsolescence and of the methodology and conclusions of much research on the topic. It placed emphasis on the distinction between synchronous and diachronous studies and on the need to correct for the size of the literature cited or used. Si...

Current systems use caching to provide high performance and possibly support disconnected operation. However, current solutions are type specific. With the advent of modular distributed operating systems and mobile machines there is a need to provide generic support for implementing cacheable/disconnectable services. We present an architecture that can be used to implement cacheable/disconnecta...
