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...

Computer animation has been a popular research topic since 1970s, when the first parametric facial model is proposed[0]. In the recent few years, a lot of techniques are proposed to model and animate faces like physical modelling, motion capture, mesh deformation etc. However, most of them require burden work of artists and assistance of expensive model. Rigging is one kind of the most popular ...

In the 1960s the isolated tropical forest enclave of Quintana Roo was targeted by the Mexican Government to serve as the cornerstone for launching what is now considered to be one of Mexico’s most successful economic development strategies – Planned Tourism Development (PTD). This paper commences with a brief review of the role of state-driven PTD in Mexico’s national economic development agend...

Across two years, we examined the effects of teachers’ attempts to implement computer supported collaborative learning (CSCL) communities in classrooms in two high schools on students’ knowledge building, strategic learning, and perceptions of the classroom environment. In year one, 429 (fall) and 317 (spring) students in the classes of 8 teachers and in year two, 946 students in the classes of...
