Development and control of a parallel endoscopic surgical robot platform for beating heart procedures
(2021-06-16)
Minimally Invasive Robotic Surgery focuses on performing surgeries using advanced robotic tools through small incisions. Taking advantage of these advanced tools and control methods, challenging surgeries such as ...
An investigation into flow and heat transfer of an ultrasonic micro-blower device for electronics cooling applications
(Elsevier, 2016-05-08)
As compact electronics increase in functionality, new electronics cooling approaches must be more effective, and they must be lower in form factor. In this paper, we investigated the cooling performance of a miniature ...
Settlement scale analysis approach to reach nearly zero energy communities
(Springer, 2020-01-01)
The European Union directive on the energy performance of buildings was revised and republished in 2010, as EPBD Recast, introducing new terms as cost-optimal and nearly zero energy levels. It mandated that by 2018 all new ...
Development of an antagonistically actuated smart joint
(Trans Tech Publications, 2017)
Shape memory alloys with their phase transformation properties; have been broadly implemented in smart structures. In this study, a functional design is presented where two wires actuate antagonistically to achieve motion ...
Discrete-time integral sliding mode control of a smart joint for minimally invasive surgeries
(IEEE, 2016)
In this work, a shape memory alloy(SMA) actuator based joint (smart joint) is controlled using a discrete-time integral sliding mode (DISM) control to guide the motion of an active catheter. Controller is designed on the ...
Influence of heat treatment parameters on the functional behavior and corrosion performance of a shape memory wire actuator
(Trans Tech Publications Ltd, 2020-04)
In the present study, the effect of heat treatment parameters on the functional response, corrosion behavior and microstructural evolution of NiTi shape memory alloys were investigated. Various heat treatment regimes were ...
Channel modelling for light communications: Validation of ray tracing by measurements
(IEEE, 2020)
Light communications, also denoted as LiFi, is promising for future wireless indoor networks. For performance evaluation, the IEEE P802.15.13 and P802.11bb standardization groups agreed upon channel models based on ...
A flexible OLED VLC system for an office environment
(IEEE, 2020)
The potential use of flexible substrate-based organic light emitting diodes (OLEDs) as curved or rolled lighting sources offers news opportunities for the implementation of visible light communications (VLC) in indoor ...
Design of compact monopulse standing wave slotted array in ku-band
(IEEE, 2019)
In modern radar and communication systems, high gain, high power capability and low-profile front-end antenna systems are frequently utilized. In this paper, a compact, lightweight, high reflection bandwidth and high gain ...
Cryogenic 1.2 to 116 GHz receiver for large arrays
(IEEE, 2018)
Current and future large arrays for radio astronomy are compared and the Next Generation Very Large Array, ngVLA, is introduced. Receiver requirements are described and a 4-feed system covering 1.2 to 116 GHz, in a single ...
