The blood pressure of spinal cord injury (SCI) patients with orthostatic syncope phenomenon was changed rapidly within short time during tilt table training and treating. In this research, the pulse arrival time (PAT) and intermittent calibration were estimated by continuous blood pressure (CBP) method of W. Chen, and observed the blood pressure changing during symptomatic. The levels of presyncope symptoms (PS) which included PS 1, 2, 3, and 4 were used to quantify the syncope levels, and evaluate. In this research, 11 subjects who were in intensive care unit of hospital were used to acquire their physiological signals of invasive blood pressure, noninvasive blood pressure (NBP) etc., and to evaluate the feasibility of CBP method. In addition, 14 normal subjects were used to compare the pulse wave signal between photoplethysmography (PLETH) and cuff measurement. Then the physiological signals were acquired during the tilt table training. The tilt angles were set at 0, 30, 45, 60 and 75 degree from 9 spinal cord injury patients with symptomatic and asymptomatic. The CBP from pulse wave signal of cuff measurement and NBP were calculated, and compared the levels of PS between CBP and NBP. In result, the correlation coefficient between CBP and invasive blood pressure was 0.83., and the CBP method between PLETH and cuff measurement was 0.88. It was significant differences between symptomatic and asymptomatic in NBP method, and among the levels of PS in CBP method. In conclusion, the estimated continuous blood pressure method could verify the discrimination of the levels of PS effectively, and provide the capability of identification of presyncope compared with NBP method. In the future, the CBP method may provide more information of blood pressure for biofeedback control of orthostatic syncope and make the criterion of reference indicator of presyncope prediction in symptomatic situation.

In this thesis, I present the result of the phase shifts of the X-ray pulses in different energy ranges of the first known accretion-powered millisecond pulsar SAX J1808.4-3658 in its 2002 outburst observed by Rossi X-ray Timing Explorer (RXTE) Proportional Counter Array (PCA), and compare to the similar phenomenon seen in 1998 outburst. To compare the pulse arrival times of different energy ranges, the precise orbital and spin parameters which reveal the correct pulse profiles are required. These parameters were refined through minimizing the variation of the pulse peak phases, yielded by folding the non-burst, 2 – 10 keV events with a model consisting of orbital Doppler Effect plus possible pulse phase drift described as a polynomial. I found the discontinuity in parameters after day 14, hence it was hard to get the orbital and spin parameters for whole 2002 outburst. Moreover, Burderi et al. (2006) reported that there was a “phase jump” during the day 14 – 17 of the 2002 outburst. Thus, I decided to remove the data in the phase jump and divided 2002 outburst into two sections, before and after the phase jump, then obtained their parameters separately. I subsequently applied these parameters to fold the 11 energy bands of data allocated by event energy to obtain their fine pulse profiles. The phase delays relative to the softest band were derived through cross-correlating the corresponding pulse profiles. The results show a soft pulse lag in the first ~14 days’ data up to 0.08 spin phase (~200 μs) and it saturates at > 9 keV, consistent with the one in 1998 outburst. On the other hand, the similar phenomenon is also seen after the phase jump but the soft lag is up to 0.12 spin phase (~300 μs), much more than the one we found in first 14 days, and the phase lag doesn’t saturate. It is believed that the energy dependent phase pulse arrival time would be caused by the spectrum on the pulsar’s hotspot. The energy dependent pulse phase behavior before the phase jump in 2002 outburst is consistent with it in 1998 outburst, but the case after the phase jump shows a huge difference – in which it shows longer soft pulse lags and no sign of saturation. It seems that the spectrum around the hotspot after the phase jump in 2002 outburst might be softer. Based on this result, we conclude that even in the same source, it might have different behaviors due to the construction of the spectra of the hotspot environments.

XTE J0929-314 is the third known accretion-powered millisecond pulsar, which was first identified by Rossi X-ray Timing Explorer ( RXTE ) during its outburst. The follow-up RXTE pointing observations of the source was made between May 2 to June 24 2002. It is a faint, high Galactic latitude, transient, ultracompace X-ray binary. Our analysis is based on the data collected by RXTE Proportional Counter Array (PCA) in GoodXenon mode with 1 μs resolution because of its weak x-ray intensity. The purpose of this thesis is to investigate the energy dependent pulse arrival time of this source. Therefore, the fine pulse profiles, which require precise ephemeris to compensate the effects from orbital motion and other long-term phase drifts for the observed pulses, are essential. We applied pulse phase analysis method to find the ephemeris. Unfortunately, because of possible hot spot movements on the surface of neutron star, no simple model can well-describe the pulse phase modulation for the whole 40 days’ observations. We alternatively attempted to find the local best ephemeris and extracted pulse profiles in seven distinct energy bands between 2 and 14 keV for each observation ID (~1 to 2 hrs exposure). The energy dependent pulse arrival time differences were obtained through cross-correlating these pulse profiles. The weighted-average result for the observations shows that hard X-ray pulses arrived up to 810μs (0.15 cycles) earlier than the soft ones from 2 to 8 keV and the lead saturates beyond 8 keV. Being compared with other accretion-powered millisecond pulsars, XTE J0929-314 has the largest soft lag. According to the two-component model, the Comptonized component has a broader (fan-like) angular distribution than the blackbody component. The Doppler boosting then significantly shifts the peak of the hard pulse producing the soft lag. Therefore, this source probably has a relatively stronger blackbody component than other millisecond pulsars which indicates that XTE J0929-314 has a softer spectrum.

MAXI J0911-655 (Swift J0911.9-6452), an accreting millisecond X-ray pulsar located in globular cluster NGC 2808, was discovered in 2016 with a pulsation period of 2.94 ms. The follow-up observations were made by Swift, INTEGER, Chandra, XMM-Newton and NuSTAR. Our analysis based on the observation data of XMM-Newton and NuSTAR owing to their better time resolution and larger effective area. In this study, we attempted to detect the energy dependent pulse arrival time lags, which have been seen in other AMXPs. To obtain the correct pulse profile, precise orbital and spin parameters are essential. We first applied the orbital and spin parameters that yielded by previous study and then refined them using pulse arrival time delay technique. These photons were further divided into several energy bands and then folded with the best orbital and spin parameters to make the pulse profiles of these bands. The pulse arrival time lags relative to the softest energy band were evaluated through cross correlation of the best fitted pulse profiles. We found the soft lags could be up to 0.24 cycle (~700 μs) in the energy range of 0.3 to 78 keV by XMM-Newton and NuSTAR observations. According to the two-component model, by the influence of Doppler boosting, the different angular distribution between Comptonized (fan-like) and blackbody (pen-like) components is an important reason to cause the soft lag. In this study, we tried to discussion the hotspot and accretion shock change for different outburst time by soft lag magnitudes.
