A quantum computer (QC) can operate in parallel on all its possible inputs at once, but the amount of information that can be extracted from the result is limited by the phenomenon of wave function collapse. We present a new computational model, which differs from a QC only in that the result of a measurement is the expectation value of the observable, rather than a random eigenvalue thereof. S...

This paper discusses the design and development of worksheets for helping notebook computer (NBC) users to compute NBC and workstation adjustments so as to assume an appropriate seated posture. The worksheets (one for male users, the other for female ones) require the following information: body height, NBC screen size, work surface height, and seat height. The worksheets contain tables for est...

We propose a control method for the optical components of a dynamically reconfigurable optical platform, the ternary optical computer (TOC). The optical components are made of liquid-crystal cell arrays (LCCAs) and polarizers, so the control method is for generating the pilot signals of the LCCAs to meet user demands. In this work, we first briefly introduce the TOC theory, the modules in the T...

PURPOSE To assess the potential advantage of intensity-modulated radiotherapy (IMRT) over 3D-conformal radiotherapy (3D-CRT) planning in postoperative adjuvant radiotherapy for patients with gastric carcinoma. METHODS AND MATERIALS In a retrospective study, for plan comparison, dose distribution was recalculated in 15 patients treated with 3D-CRT on the contoured structures of same CT images ...

Background: Trajectory planning is the premise of control orthopedic robots, which directly related to safety human body. However, date, trajectory robots has been restricted lines and spline curves. This limits flexibility robot leads unsatisfactory performance. In this paper, a method based on improved RRT* B-spline curve proposed in order improve accuracy flexibility. Method: Firstly, combin...

Within the next few years it is envisaged that a number of computer assisted surgery products will become available. For many surgical procedures, outcome of surgery will rely on the accuracy and repeatability with which a computer assisted surgical tool performs its task. This paper presents a Computer Assisted Orthopaedic System (CAOS) which takes an image guided approach to planning and impl...

A corrective osteotomy is a frequently required procedure for symptomatic malunions of the distal radius. A multitude of different methods have been proposed for correction of distal radius malunions. However, precise correction of a severe malunion that requires simultaneous adjustment of displacement and rotation in multiple planes remains a challenge. Technological advancements have resulted...
