NOVEL DIGITALIZED MARKERS FOR SCREENING AND DISEASE TRAJECTORY TRACKING IN CLINICAL TRIALS

Currently, to enroll participants into pharmaceutical trials strenuous and costly procedures are applied to test whether participants meet inclusion criteria or not; this includes travel to clinics, costly brain imaging, invasive assessments, or costly f2f assessments with experts. Moreover, screening for such inclusion criteria in clinical trials has significant fail rates and significant resources have to be spent on participant screening to enroll only a fraction of them (10%). Standard cognitive assessment typically uses a set of speech-based cognitive tests which have the potential to be conducted remotely in telecommunication settings. However, only recently speech analysis and automatic speech recognition, as well as semantic speech processing have become mature enough to automate such speech-based testing procedures. The European DeepSpA project aims to replace in-person manual pre-screening procedures by remote (semi-)automated analyses methods detecting relevant phenotype for novel Alzheimer trials automatically. To evaluate the feasibility of the phone-based solution in a real-world scenarioand examine the predictive potential for prognostic diagnosis, information extracted over the phone from the participant's speech in cognitive and narrative speech tasks will be analyzed for its usefulness for remote pre-screening. 120 participants at preclinical stages of cognitive impairment will be recruited from the local memory clinic. At baseline, a complete dataset (including speech recordings) will be collected, consisting of clinical data and biobank materials, e.g. blood samples, MRI and cerebrospinal fluid. After 6 months the participants will be called for a brief remote follow up evaluation on the phone consisting of a short interview on subjective cognitive decline, a verbal memory task, and fluency tasks in which speech features will be collected through a semi-automatic phone-based interface. Final data sets will be compared to each other. We expect to obtain comparable results between the telecommunication administration method and the traditional application. First preliminary results as well as a working demo version will be presented at the preconference. Built on existing speech technologies, we expect this first-of-its-kind service to allow to remotely conduct neurocognitive testing thus pre-screening of potential trial participants. This will significantly reduce the overall costs associated with the screening and speed up the trials' preparatory activities.

Enhanced the Accuracy of Specification of Maximum Permitted Emission Levels for TV White Space Devices

In this paper, we present a proposed geo-location database calculations which needs to perform in order to obtain high accuracy of maximum permitted emission levels for TV white space devices (WSDs) operating in the digital terrestrial television (DTT) frequencies. The study is mainly aimed at to analuze the impact of channel power condition in band ( ) and power out band ( ) for WSD for DTT reception in hilly environment under different altitudes. The proposed methodology for the calculation of such emission levels considers the effect of environment and hight of DTT reception. Both theoretical study and mathematical investigations are conducted in order to model and characterize such complex communication medium for WSDs. The propagated maximum permitted emission levels varies from one place to another due to time varying channel condition as a result of obstacles and distance between the transmitter and receiver. The study achieved according to the methodologies, results and recommendations addressed by the European Conference of Postal and Telecommunication administration CEPT. The comparison between proposed model and traditional one has been done by CEPT. The result shows that the proposed model with various altitudes in the hilly terrain environment obtain more accurate maximum permitted emission levels for WSDs, Which increase by 25.609 dBm and 25.61 dBm for and respectively at 100 altitude accordingly.

Validation of an automatic tool for the assessment of image quality in digital tele-echocardiography

We investigated a novel tool for assessing image degradation in tele-echocardiography. Different video recordings from an echocardiographic examination were transmitted using commercial videoconferencing equipment via a local area network. Different compression schemes were selected, ranging from MPEG 1 to MPEG 4, with transmission at different bit rates ranging from 1.0 to 4.5 Mbit/s. Three methods were used to compare the transmitted and received video sequences: the peak signal to noise ratio, the Double Stimulus Impairment Scale (DSIS) and the National Telecommunication and Information Administration Virtual Quality Metric (VQM). The results showed that the most useful grading procedure was the subjective DSIS. There was a high correlation between the DSIS results and the VQM. The VQM could be thus an effective tool for evaluating tele-echocardiography transmission systems, avoiding the costs and times associated with conducting subjective tests in repeatable conditions.

It discusses key characteristics, model projects, and lessons learned in three categories related to community development: rural resource development, urban asset mapping, and community economic development. It includes a summary of the results of program-wide evaluations conducted periodically since the program started. The paper concludes with a section that discusses elements which successful projects have in common, for the use of community development practitioners who are considering using ICTs to amplify, support, or augment their efforts.

OneLink Manager™ EMS for the 7R/E™ Switch

Developing the 7R/E™ Packet Network Solution requires merging traditional telecommunication operations, administration, maintenance, and provisioning (OAM&P) capabilities with the fast-paced, high-churn world of data switching and dedicated element management systems (EMSs). The OneLink Manager™ EMS is designed to merge these worlds. It allows rapid integration of disparate technologies and equipment from third-party vendors into a coordinated OAM&P system with a unified standards-based interface. The architecture can grow in breadth and depth of function and in scale to support the largest switching/data centers.

Aux origines de « l'autonomie » des télécommunications françaises, la loi de 1923

After forty years of reflection and propositions, the Third Republic finally produced a reform in 1923 which created the PTT supplementary budget. This legal framework was to govern the activities of the Post and Telecommunication administration until the 1990 reform. It was based on a notion of « autonomy » which, in the author's view, will remain eternally out of reach.

Effectiveness and Efficiency in Industrial Training

Companies spend a great deal of money on industrial training. In our practice as training consultants within the Netherlands Post and Telecommunication Administration, we come across many reasons why this training effort does not have the desired effects. This article is the first of a series of three in which we share the results of our field studies on this subject and our ideas for improving the effectiveness and efficiency of industrial training. The first article focuses on sources of ineffectiveness and inefficiency of training efforts.

Towards Text Communication Services

Standards are important for the widespread and economical introduction of many text and image-based communication services. The role of standards in the policies and developments of the French Post Telecommunication and Telediffusion Administration for a variety of telematic services is discussed.

Budgeting design and organizational capabilities: Multicriterion planning of telephone services

Telephone services are one example of a type of activity where the measure of success tends to be multidimensional: for example, costs and several service criteria are often used as performance indicators. Budgetary planning should be adapted accordingly, using different ‘mixes’ of service and cost as the alternatives that are discussed in a decentralized planning dialogue. Such a dialogue has to be designed with attention to the abilities of the organization: people's knowledge of possible alternatives and preferences, their ability to communicate this knowledge, etc. In this paper, the requirements of some alternative ways of designing multiobjective planning are related to show such abilities in a particular case, that of the National Swedish Telecommunication Administration.

System Considerations for European Communication Satellites

A regional communication satellite system is being planned for Europe to satisfy the future needs of the European Conference of Post and Telecommunication Administration (CEPT) and the European Broadcasting Union (EBU). A model of the mission for the satellite system, based on the estimated future traffic requirements of the potential customers, has been defined to serve as a basis for system design. Starting with the postulated traffic model and with a review of the various system constraints, the present paper defines the parameters and the tradeoffs leading to the choice of the communication techniques fulfilling the requirements of the mission model. The resulting baseline communication system and its major characteristics are described. Alternate system design options are presented and commented upon. Some of these options would enhance the performance of the system but would generally involve more advanced techniques and would represent a larger technological risk. Finally, research and development topics in the field of communication technology are identified. Some of these topics are being investigated and some of the results are described in other papers.

The performance requirements of a television monitor receiver (nyquist demodulator) and methods of measurement

A high-quality monitor receiver is normally used at television transmitter stations for measuring and monitoring purposes. The performance of this receiver is discussed on the basis of the ideal characteristics, as specified by C.C.I.R., and the characteristics which lie within practical tolerance limits. The problem of testing the receiver is considered, and selected measuring procedures, which have been used in an extensive test service for the Norwegian Telecommunication Administration, are described.
