In large software systems some code may not be under the direct control of security conscious developers. This situation arises when dealing with third party libraries, plugins added by users, or code written by a large team’s novice programmer. Securing the whole system is difficult as an error in a library or a malicious plugin can compromise the entire program. To mitigate this, it is desira...

We present an intelligent help system for the Unix operating system called Aran. Aran is a passive, knowledge-based help system whose main goal is to help users deal with problems related to Unix operation. Aran gives the user access to different kinds of information, and it is designed to help the user accomplish a given task, while, at the same time, expanding the user's knowledge of the oper...

STUDY OBJECTIVE To determine if a self help intervention, delivered via written interactive materials (the "Walk in to Work Out" pack), could increase active commuting behaviour (walking and cycling). DESIGN Randomised controlled trial. The intervention group received the "Walk in to Work Out" pack, which contained written interactive materials based on the transtheoretical model of behaviour...

OBJECTIVES To examine variation in provision of assistive technology (AT) devices and the extent to which such variation may be explained by patient characteristics or Veterans Health Administration (VHA) administrative region. DESIGN Retrospective population-based study. SETTING VHA. PARTICIPANTS Veterans poststroke in fiscal years 2001 and 2002 (N=12,046). INTERVENTIONS Not applicable...

This study investigated the use of a word processor for enhancing the academic outcomes of three students with writing disabilities in a junior high school. A single-subject ABAB design was used to compare academic output produced during class time with and without a computer equipped with a word processor. The number of spelling errors, the number of reading errors, and the number of words use...

As a step toward developing a general method for determining the underlying geometric structure of two timescale optimally controlled nonlinear systems, we define a degenerate class of two timescale optimal control problems, called completely hyper-sensitive problems, and propose an indirect solution method for this class of problems. The method uses a dichotomic basis to split the Hamiltonian ...

Type 2 diabetes is more prevalent and severe among African Americans. Even within the Veterans Health Administration, which is thought to have minimized barriers in access to care, racial disparities in glucose control and outcomes persist. This Issue Brief summarizes work testing two novel interventions--one-on-one peer mentoring (a "buddy system") and financial incentives--designed to help pa...

The Unified Modelling Language (UML) is a language that helps to visualize, design and document models of large and complex systems. Terminology and notation of visual modelling can be used as common high level object oriented language for design of the mechatronic systems. Index terms UML, mechatronics, CASE tool, MATLAB, Simulink, Stateflow

The DE-4208 RESORT tele help prototype provides remote support for disabled users of PC based Rehabilitation Technology (RT) and their care persons in order to reduce existing barriers in daily usage and service of RT. The current RESORT prototype and its interface specification support also synchronisation of single switch users over narrow bandwidth network channels. The IP based RESORT syste...
