The purpose of this investigation was to evaluate the efficacy of expansion points (EXP) intervention with a modified criterion for preschool children with speech sound disorders (SSD). Three preschool-aged children were enrolled in a single-subject multiple baseline intervention study. Intervention took place over 16 sessions. Pre- and post-intervention data are provided. Three outcome measures (generalization to probe words and gains in percent consonants correct, PCC, in words and in conversation) were evaluated to measure the effectiveness of the EXP intervention. All three of the participants demonstrated gains by the end of the intervention phase when measuring PCC in single words. Two of the three participants demonstrated gains in PCC in conversational speech. Progress on individual phonemes was variable across participants. Utilizing the EXP approach, two of the three children showed gains in all three outcome measures. One child showed variable performance in one outcome measure, improvement in one, and a decrease in one. Findings suggest that EXP should be further explored to evaluate intervention efficacy.

“…A complete programming environment called SCORE based on the dataflow model was developed for stream oriented computing which supported phased reconfiguration and dynamic rate dataflow [12]. Many recent architectures developed in academia include Morpheus [13], Montium/Chameleon system from University of Twente [14], Adres [15] from IMEC in Belgium, Imagine [16] from Univ. of Stanford and REDEFINE from Morphing Machines [17].…”

Programmable hardware built on a regular architecture can partially alleviate the problem of increased defect densities associated with transistor scaling by dynamically wiring around the defects [1]. The fine granularity of FPGAs is however unsuitable for effectively exploiting runtime reconfiguration because of the high overheads involved. A coarse grain reconfigurable array with malleable communication links -reMORPH -is proposed in this paper. The compute tile uses DSP48E and BRAM embedded blocks in a Xilinx FPGA and has a very low footprint of about 200 slice LUTs. The semi-systolic near neighbour communication interconnect can be dynamically reconfigured for each "epoch" of computation. The "epoch" or phases of the application are obtained via profiling or static data flow analysis. Some of the links between the compute tiles are changed during the reconfiguration phase which drastically reduces the context switch overhead enabling high performance/area applications to be built on this fabric.

1 Personal mobile computingIn recent years, technology drivers changed significantly. High-end systems used to direct the evolution of computer architectures and systems. Now low-end systems drive technology, due to their large volume and attainable profits. Advances in technology enable portable computers to be equipped with wireless interfaces, allowing networked communication even while on the move. Whereas today's notebook computers and personal digital assistants (PDAs) are self contained, tomorrow's networked mobile computers are part of a greater computing infrastructure.Two trends -multimedia applications and mobile computing -will lead to a new application domain and market in the near future. Personal mobile computing (often also referred to as ubiquitous computing [17]) will play a significant role in driving technology in the next decade. In this paradigm, the basic personal computing and communication device will be an integrated, battery-operated device, small enough to carry along all the time. This device will be used as a replacement of many items the modern human-being carries around. It will incorporate various functions like a pager, cellular phone, laptop computer, diary, digital camera, video game, calculator and remote control. An important issue will be the user interface: the interaction with its owner. The device will support multimedia tasks like speech recognition, video and audio.Wireless networking greatly enhances the usability of a personal computing device. It provides mobile users with versatile communication, and permits continuous access to services and resources of the landbased network. A wireless infrastructure capable of supporting packet data and multimedia services in addition to voice will bootstrap on the success of the Internet, and in turn drive novel networked applications and services.However, the technological challenges to establishing this paradigm of personal mobile computing are non-trivial. In particular, these devices have limited battery resources, will handle diverse data types, and will operate in environments that are insecure, unplanned, and show different characteristics in time.Five years ago, in 1995, we started the MOBY DICK project, whose main focus was on the design of such a novel and versatile machine [12]. The MOBY DICK project started as a joint European project (Esprit Long Term Research 20422) to develop and define the architecture of a new generation of mobile handheld computers. The design challenges have been primarily in the creation of a single architecture that allows the integration of security functions (e.g. payment), externally offered services (e.g. airline ticket reservation), personality (i.e. these devices know what their owners want), and communication (mobile internet terminal). After one year, the research themes focussed on: systems architecture of
