A multi-channel sEMG signal acquisition system based on the analog front-end chip ADS1299 is designed. The whole consists of a 2×9 high-density electrode array, high-precision A/D conversion chip; MCU named STM32F103C8, an upper computer, and PC. We carried out array design, introduction function chip, circuit design part. test results show that designed in this paper can ideally collect 8 chan...

It is useful to build agents to mediate in the use of complex software systems. To understand some dimensions of mediating agents, this thesis presents an agent design for the automatic use of a computer algebra system (CAS). Such an agent must take a task specification from the user and produce a plan for achieving the task while also producing a plan for the CAS. In particular, I use the Soar...

There  has  been  considerable  debate  over  what  the  sources  of  morphological  variation  in  second  language acquisition  are.  From  among  various  hypotheses  put  forth  on  the  topic,  the  feature  reassembly  hypothesis (Lardiere, 2005) assumes that it is the reconfiguration of features in the L2 which causes variation between the performance of natives and non-natives. Acknowle...

this paper aims to provide first a theoretical discussion of the ontology problem in MAS and second an introduction to how to design and implement knowledge intensive agents with CommonKADS methodology. The paper is organized around three questions: (1) is knowledge a necessary entity in Agent Systems? (2) What is the problem for individual knowledge intensive agents to cooperate? (3) Provide a...

This chapter presents results from a meta-analysis that compares the effectiveness of Web-based instruction (WBI) to classroom instruction (CI). The results suggest that when the same instructional methods are used, WBI and CI are equally effective for teaching declarative knowledge. However, the instructional methods and course design features incorporated in WBI are critical factors in determ...

In this paper we address the problem of automatic arrangement of cameras in a 3D system to enhance the performance of depth acquisition procedure. Lacking ground truth or a priori information, a measure of uncertainty is required to assess the quality of reconstruction. The mathematical model of iso-disparity surfaces provides an efficient way to estimate the depth estimation uncertainty which ...

The effect of temperature change on dynamic performances of an industrial robot with six axes of freedom is studied in this paper. In general, the strain and stress are produced not only by the external exciting force, but also by temperature change. The strain energy that is caused by temperatureThis paper describes how the temperature variation effects the dynamic performance of an indu...
