Object tracking and identification by quantum radar
(SPIE, 2019)
Quantum Radar is a promising technology that could have a strong impact on the civilian and military realms. In this study we introduce a new concept design for implementing a Quantum Radar, based on the time and polarization ...
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 ...
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 ...
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 ...
An MMIC low-noise amplifier design technique
(IEEE, 2016-03)
In this paper we discuss the design of low-noise amplifiers (LNAs) for both cryogenic and room-temperature operation in general and take the stability and linearity of the amplifiers into special consideration. Oscillations ...
A robust estimation model for surgery durations with temporal, operational, and surgery team effects
(Springer Science+Business Media, 2015-09)
For effective operating room (OR) planning, surgery duration estimation is critical. Overestimation leads to underutilization of expensive hospital resources (e.g., OR time) whereas underestimation leads to overtime and ...
Design and kinematics of 4- DoF multi-purpose wearable mechanical arm (MUWA) support for enhanced operation stability
(IEEE, 2019)
A low-cost motor-less simple wearable mechanical arm support unit is presented as a viable alternative to todays assistive exoskeleton support units. By limiting the functionality of the device to stabilization rather than ...
An extension to the classical mean–variance portfolio optimization model
(Taylor & Francis, 2019-07)
The purpose of this study is to find a portfolio that maximizes the risk-adjusted returns subject to constraints frequently faced during portfolio management by extending the classical Markowitz mean-variance portfolio ...
