The purpose of this study was to investigate the effects of different foot positioning on bilateral erector spinae (ES) and gluteus maximaus (GM) activation during sit-to-stand in stroke patients using surface electromyography(EMG). Fifteen randomly selected stroke patients participated and were required to perform sit-to-stand (STS) with three different strategies as follows: 1) symmetric foot position,...
Periprosthetic joint infection (PJI) is a devastating complication after arthroplasty. Two-stage reimplantation procedure is the most common practice to prevent the reoccurrence of PJI. However, it should be assisted by a rapid, accurate and comprehensive bacteria detection tool. In this study, a new integrated microfluidic system capable of performing sample pre-treatment, a nanogold detection to...
The main focus of this paper is on system identification of an active magnetic bearing system (AMB) using genetic algorithm (GA) for optimal controller design purpose. In the first step, an analytical model of the system is derived using principle of physics and taking into account both the rigid body and bending body modes of the system. In the next step, as AMB system is inherently open-loop unstable,...
Positivism, in defining what it means by "explanation," leads to certain requirements for theory to satisfy. We refer to explanation as defined in the positivist philosopher Carl G. Hempel's deductive-nomological model of explanation. The requirements pertain to the operationalization of a theory, the precision with which a theory needs to be stated, and the composition of a theory. Researchers...
PhytoPET is a modular positron emission tomography (PET) system designed specifically for plant imaging. The PhytoPET design allows flexible arrangements of PET detectors based on individual standalone detector modules built from single Hamamatsu H8500 position sensitive photomultiplier tubes and pixelated LYSO arrays. We have used the PhytoPET system to perform preliminary corn plant imaging studies...
Summary form only given. While innovation in manufacturing continues to push the envelope of CMOS device scaling toward the physical limit, at the meantime, system integration has found an alternative path to delay the limitation by using silicon-interposer based design with through-silicon-via (TSV) or true 3-D IC die stacking to cram more devices within the same chip pacakge. These solutions enable...
Students' progress and development in an engineering program is often left unexamined when much of the attention is placed on benchmarking students' performance against absolute standards. This study aims at tracking students' development on program learning outcomes across a two-year associate degree engineering curriculum. Nine Likert-scale items were designed to measure students' perception of...
Kansas State University Dense Plasma Focus KSU-DPF is a 12.5 µF, 20kV, 2.5 kJ DPF machine that was commissioned at the Plasma Radiation Physics Laboratory, Kansas State University (KSU)1 early 2010. The machine was designed as a compact, nanosecond, multi-radiation source for applications in nuclear science and engineering. During the Deuterium-Deuterium D-D discharge (17 kV, 140 kA and 5 mbar) the...
Researchers in academic disciplines, including but not limited to information systems, have long been aware of, but have not linked, two research issues: one issue is the lack of relevance, despite the plethora of rigor, in their research, the other issue is the distinction between statistical significance and practical significance, where the latter is no less important than the former. In this essay,...
This paper focuses on how to improve the characteristics of multi-walled carbon nanotube (MWCNT) sheet transparent, conductive films (TCFs), such as their sheet resistance (Rs) and optical transparency (T), for TCF electrodes. In this work, MWCNT sheets under went an acid treatment in HNO3 to reduce the Rs of the MWCNT sheet. The Rs of the MWCNT sheets is largely dependent on the immersion time in...
We have investigated the photoreflectance characteristics and the photovoltaic performance of Cu(In, Ga)Se2 (CIGS) thin-film solar cells that have CdS layers prepared by chemical bath deposition (CBD). The CdS was deposited on CIGS by three different conditions. (I) CdSO4 0.014 M, thiourea 0.014 M, NH4OH(30%) 60 ml, (II) CdSO4 0.0015 M, thiourea 0.074 M, NH4OH(30%) 56 ml, and (III) CdSO4 0.0015 M,...
