Enhancement of magnetic properties in CoCrPt longitudinal recording media by Cr75Ti25/CoTi bilayer (1999)

Effects of the Cr75Ti25/CoTi bilayer on the magnetic and crystallographic properties in CoCrPt longitudinal recording media were investigated. CoCrPt(30 nm)/Cr75Ti25(X nm)/CoTi(50 nm) films were deposited on glass substrates heated at 250 °C by a dc magnetron sputtering method. Coercivity increased from 2200 to 3200 Oe by incorporating a 50 nm thick Cr75Ti25 intermediate layer between the CoCrPt magnetic layer and the CoTi underlayer. From x-ray analyses, the rather strong Co(101̄0) diffraction was developed in addition to Co(112̄0) diffraction in CoCrPt/Cr75Ti25/CoTi films, while only Co(112̄0) diffraction was observed in CoCrPt/CoTi films. Transmission electron microscopy image confirmed that the small grain size of 18 nm in both types of films. This enhancement of the coercivity can be attributed to the increase of magnetic decoupling effect through the Cr segregation at the grain boundaries of the magnetic layer. In addition, the presence of the Co(101̄0) plane, and small grain size due to the B2 structure intermetallic compound underlayer should influence the magnetic properties of CoCrPt/Cr75Ti25/CoTi films.

Multidetector CT Evaluation of Active Extravasation in Blunt Abdominal and Pelvic Trauma Patients (2008)

Timely localization of a bleeding source can improve the efficacy of trauma management, and improvements in the technology of computed tomography (CT) have expedited the work-up of the traumatized patient. The classic pattern of active extravasation (ie, administered contrast agent that has escaped from injured arteries, veins, or urinary tract) at dual phase CT is a jet or focal area of hyperattenuation within a hematoma that fades into an enlarged, enhanced hematoma on delayed images. This finding indicates significant bleeding and must be quickly communicated to the clinician, since potentially lifesaving surgical or endovascular repair may be necessary. Active extravasation can be associated with other injuries to arteries, such as a hematoma or a pseudoaneurysm. Both active extravasation and pseudoaneurysm (unlike bone fragments and dense foreign bodies) change in appearance on delayed images, compared with their characteristics on arterial images. Other clues to the location of vessel injury include lack of vascular enhancement (caused by occlusion or spasm), vessel irregularity, size change (such as occurs with pseudoaneurysm), and an intimal flap (which signifies dissection). The sentinel clot sign is an important clue for locating the bleeding source when other more localizing findings of vessel injury are not present. Timely diagnosis, differentiation of vascular injuries from other findings of trauma, signs of depleted intravascular volume, and localization of vascular injury are important to convey to interventional radiologists or surgeons to improve trauma management.
Why do people fitted with hearing aids not wear them? (2013)

The most important issues were around hearing aid value, i.e. the hearing aid not providing enough benefit, and comfort related to wearing the hearing aid. Identifying factors that affect hearing aid usage are necessary for devising appropriate rehabilitation strategies to ensure greater use of hearing aids.
Stray neutral current problems and analysis associated with multiple ATS generator installations (2002)

In generator installations where you have more than one 3-pole automatic-transfer-switch (ATS) on a 4-wire system, stray neutral currents and unwanted magnetic fields may arise. These stray currents and fields can cause a multitude of problems. Magnetic fields created by stray neutral currents can cause objectionable current on the conduit system. Objectionable current of this type can cause voltage rises on the grounding system. Geometries of stray neutral current paths can cause magnetic fields through areas of buildings that may cause problems with sensitive electronic equipment. Ground fault protection devices may detect incorrect ground fault condition. The presence of stray ground currents in multi-ATS installations is dependent on equipment selection and bonding connection points, whereas the magnitude of these currents depend on the system geometry, raceway size/types, and other factors. This paper looks at several stray neutral configurations tested in the Vanderbilt Power Laboratory.
The Reservisor automated airline reservation system: combining communications and computing (1994)

Shortly after the beginnings of the computer in the mid-1940s, a machine appeared that was the first in a long line of important commercial systems integrating communications and processing: the Reservisor airline reservation system built by the Teleregister Corporation. A few parts of the original have been preserved at the Smithsonian Institution, and there are enough records to understand both the basic issues in the airline industry that led to the development of this remarkable device and how the machine helped solve some of the problems of rapidly evolving air-transport technology. This article also discusses the place of the Reservisor in the larger view of the development of information technology.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Challenges of State Institutions in Environmental Protection: A Case of Taraba State, Nigeria (2021)

This study examined the challenges of state institutions in environmental protection in Nigeria using the case of Taraba state. The institution theory was used as a theoretical framework for the study. The study adopted a descriptive design method using desktop review of secondary materials. Content analysis was used in analyzing the data. The findings of the study revealed that some of the challenges of the state environmental protection institutions include lack of political will, inadequate funding, inadequate qualified personnel, inadequate environmental protection infrastructures, poor condition of environmental protection laboratory, lack of office buildings for staff and poor capacity development. The study also revealed that since the creation of the Ministry of Environment in year 2000 in Taraba state, it is only in 2001, 2013 and 2014 that the ministry received up to 4% of the budgetary allocation of the state. The myriad of challenges have greatly constrained the capacity of the state institution to effectively achieve its mandate of environmental protection. Based on the findings, the study recommends the need for more political commitment to the issues of environmental protection through increased funding, employment of qualified personnel, establishment of environmental protection laboratories and increased capacity development.

Development of non-contacting, non-leaking spiral groove liquid face seals (1994)

A non-contacting and non-leaking liquid face seal operates with zero visible leakage of full face separation during running. It typically uses some face pattern to eliminate fluid leakage and generate force to separate the faces. Because of the separation, the seal will not wear out and frictional power consumption is low. Several such seals had been developed in the author`s laboratory based on spiral groove pumping principles. A test rig with variable seal closing force control was used to test a 57 mm diameter shaft size seal in water, both statically and dynamically with speeds up to 3600 rpm. The maximum dynamic sealing pressure achieved in these tests was 2.8 MPa. The seal face temperature rise was as low as 7{degrees}C. The seal design concepts wee also successfully applied to a 38 mm diameter shaft size compressor gear box oil face seal running at 25000 rpm with a fixed balance diameter. The overall lab and field test data showed that non-contacting and non-leaking seals were feasible. 5 refs., 9 figs., 3 tabs.
LiDDM: A data mining system for linked data (2011)

In today’s scenario, the quantity of linked data is growing rapidly. The data includes ontologies, governmental data, statistics and so on. With more and more sources publishing the data, the amount of linked data is becoming enormous. The task of obtaining the data from various sources, integrating and fine-tuning the data for desired statistical analysis assumes prominence. So there is need of a good model with efficient UI design to perform the Linked Data Mining. We proposed a model that helps to effectively interact with linked data present in the web in structured format, retrieve and integrate data from different sources, shape and fine-tune the so formed data for statistical analysis, perform data mining and also visualize the results at the end. 1.
Formal specification of FFHMIPv6 using PVS (2009)

Handover is a critical process in wireless networks, which determines the quality of communications, especially the real-time connections. Currently many protocols on handover have been proposed to meet the demand of IPv6 wireless communications, most of which have been appraised using simulation, testing, or both; few protocols have been specified and verified using Formal Methods. In this research, we apply Formal Methods to formally specify the new proposed fast handover protocol, Flow-Based Fast Handover Method for Mobile IPv6 Network (FFHMIPv6) [1]. To concentrate on the essence of the protocol, the best scenario in [1] is adopted as the object of the formal specification, and the best scenario is abstracted into a more concise structure to facilitate the specification. The formal specification provides the basis to formally verify the basic characteristics of safety and the proposed efficiency in future research. The formal specification is implemented using the Prototype Verification System (PVS) [2], which is a powerful formal specification and semi-automated verification environment.
The Effect of Passenger Age and Gender on Young Driver Crash Risks (2008)

This paper studied the effect of passenger age and gender on young driver fatal crash risk using police-reported crash data in Louisiana from 1999 to 2004. Young drivers were divided into three age groups: 16, 17, and 18-20 by gender. Passengers were grouped into 15-17 and 18-20 years of age by gender. A series of analyses of young drivers and young passengers were conducted to study their risks of being involved in fatal crashes. Relative risks and crash rates were used to measure crash risk. The analyses followed step by step disaggregation of driver/passenger characteristics, including the number of passengers, passenger age, and passenger age and gender for each driver age and gender group. It was found that young drivers are negatively impacted by young passengers, especially from their own peer age groups. However, the presence of adult passengers reduces their crash risks. 16 and 17 year old drivers have similar risk patterns that are much higher and different to those of 18-20 year old drivers. 16 and 17 year old drivers are associated with the highest crash risks when driving with their same gender and age group passengers, with male to male driver-passenger combination having higher risk than female to female driver-passenger combination. As age progresses, crash risk differences between male and female young drivers also increase. TRB 2008 Annual Meeting CD-ROM Paper revised from original submittal.
Temperature-Aware Register Mapping in GPGPUs (2016)

Various architectural-based techniques have been proposed to reduce power consumption in GPGPUs. However, these techniques mostly ignore temperature of GPGPUs. In this paper, we focus on the register file and propose a new technique to reduce its peak temperature. Register file in GPGPUs is very large, even larger than caches, to support thousands of simultaneously execution threads. This makes register file a power-hungry component in GPGPUs and increases its heat dissipation. We propose Distant wArp Register maPping (DARP) to maximize distance between warp registers. By maximizing distance between consecutively accessed regions of the register file, we minimize the hotspots in the register file, and hence reduce the peak temperature. Furthermore, we power gate unallocated registers and reduce voltage of idle registers to reduce leakage power and so the temperature further. To overcome performance penalty of voltage scaling, we change voltage of registers in granularity of regions and reduce the number of state switching in register file. Overall, our optimization techniques reduce peak temperature by 5.02°C with negligible impact on performance.
A new model for the performance evaluation of synchronous circuit switched multistage interconnection networks (2002)

Patel (1981) proposed a probabilistic approach to analyze the performance of multiprocessor systems using synchronous multistage interconnection networks (MINs) based on a uniform reference model and the assumption of independent requests. Through extensive simulation, the authors have found that, in many cases, their model will result in rather significant inaccuracy. the factors which cause inaccuracy in Patel's model are investigated in detail. A new queueing model is then proposed and is shown to be very accurate. Since only six states are needed, this new model is very efficient computationally.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Increased Oxidative Stress in Prepubertal Severely Obese Children: Effect of a Dietary Restriction-Weight Loss Program (2005)

Oxidant-antioxidant status was investigated in a group of severely obese prepubertal children in comparison with healthy subjects and in relation to a dietary restriction-weight loss program. All subjects underwent anthropometric measurements and determination of lipid profile, lag phase, malondialdehyde (MDA), and vitamin E. Compared with controls, obese children had a significantly higher body mass index (BMI) (28.97 +/- 2.42 vs. 16.03 +/- 1.88 kg/m2; P = 0.0002) and waist-to-hip ratio (WHR) (0.89 +/- 0.03 vs. 0.80 +/- 0.01; P = 0.0004); lag phase and vitamin E levels were significantly decreased [24.05 +/- 16.21 vs. 43.16 +/- 10 min (P = 0.004) and 21.12 +/- 14.96 vs. 35.54 +/- 13.62 micromol/liter (P = 0.02), respectively], whereas MDA was significantly increased (0.90 +/- 0.31 vs. 0.45 +/- 0.24 nmol/mg; P = 0.001). Both lag phase and MDA significantly correlated with BMI [respectively, r = -0.34 (P = 0.004) and r = 0.57 (P = 0.002)] and WHR [respectively, r = -0.63 (P = 0.0001) and r = 0.38 (P = 0.04)]. Oxidant status normalized after 6 months of dietary restriction [lag phase, 59.11 +/- 14.74 min (P = 0.002); MDA, 0.47 +/- 0.09 nmol/mg (P = 0.003)], which was associated with a reduction of BMI (27.34 +/- 1.87 kg/m2; P = 0.003), WHR (0.87 +/- 0.02; P = 0.001), and fat mass (34.49 +/- 2.68%; P = 0.008), but returned to baseline levels together with fatness indexes after another 6 months of free diet. Altered oxidant-antioxidant status is already present in prepubertal severely obese children and is reversible with a dietary restriction-weight loss program, which should be highly encouraged and maintained over time in this age group.
Communicating the value of fringe benefits to employees. (1984)

In a city where competition for employees was extremely high, one clinic kept its edge by offering a generous benefits package. Problems arose, though, because the employees did not fully appreciate the value of their fringe benefits. A concise and effective written communication tool was therefore developed, informing each employee of the cost and value of his personal fringe benefits. The figures accompanying this article offer every administrator not only an example of benefits analysis, but also a valuable basis for comparison.
Declarative Debugging of Lazy Functional Programs. (1992)

This paper is organized as follows. First a simple declarative debugger for diagnosing incorrect answers in pure Prolog programs is presented. The debugger is somewhat more abstract than other published debuggers and is written in a subset of NU-Prolog which has well defined declarative semantics. Next a simple functional programming language with (initially) non-lazy evaluation is described. We show how such a language can be debugged in an equivalent way to Prolog. Lazy evaluation is then introduced and we show how the debugger can be generalised to handle this. A refinement which reduces the complexity of questions to the user is also presented. The functional programming language we use is implemented by transformation into Prolog. Though our discussion is based on this language and implementation, we hope it will be obvious how the ideas can be adapted. A summary of the debugging algorithm in abstract terms is given after the description of our implementation. Finally, we consider related work and possible extensions then conclude. 2 Declarative debugging of logic programs
Design and Applications of a 300–800 MHz Tunable Matching Network (2013)

In this paper, the optimized design, characterization and applications of a broadband 300-800 MHz (~ 91% fractional bandwidth) digitally-controlled tunable matching network is presented. The design employs PIN diodes as switching components and a repetitive structure of basic cells using lumped reactive elements. After an intensive and complex optimization process, a Smith chart coverage (return losses better than 10 dB and losses lower than 2 dB) above 60% is obtained in all the bandwidth reaching 75% in the middle of the band (400-700 MHz). The potential of the manufactured tunable matching network for antenna mismatch compensation, antenna bandwidth extension and power amplifier efficiency improvement in back-off is showed.
PhaseU: Real-time LOS identification with WiFi (2015)

WiFi technology has fostered numerous mobile computing applications, such as adaptive communication, finegrained localization, gesture recognition, etc., which often achieve better performance or rely on the availability of Line-Of-Sight (LOS) signal propagation. Thus the awareness of LOS and Non-Line-Of-Sight (NLOS) plays as a key enabler for them. Realtime LOS identification on commodity WiFi devices, however, is challenging due to limited bandwidth of WiFi and resulting coarse multipath resolution. In this work, we explore and exploit the phase feature of PHY layer information, harnessing both space diversity with antenna elements and frequency diversity with OFDM subcarriers. On this basis, we propose PhaseU, a real-time LOS identification scheme that works in both static and mobile scenarios on commodity WiFi infrastructure. Experimental results in various indoor scenarios demonstrate that PhaseU consistently outperforms previous approaches, achieving overall LOS and NLOS detection rates of 94.35% and 94.19% in static cases and both higher than 80% in mobile contexts. Furthermore, PhaseU achieves real-time capability with millisecond-level delay for a connected AP and 1-second delay for unconnected APs, which is far beyond existing approaches.
Phosphorus Vacancy as a Deep Level in AlInP Layers (2000)

Deep levels in AlInP layers, grown by metal-organic chemical vapor deposition (MOCVD) with various V/III mole ratios, have been carefully investigated by deep-level transient spectroscopy (DLTS). A deep level originating from phosphorus vacancy was observed with the activation energy of 0.65 eV. Examining this phosphorus-vacancy-related deep level provided a relatively simple means of understanding the phosphorus vacancy in AlInP, thus allowing us to determine an appropriate V/III mole ratio for growing AlInP.
<i>Review:</i> Information Technology and Organizational Performance: An Integrative Model of IT Business Value1 (2004)

Despite the importance to researchers, managers, and policy makers of how information technology (IT) contributes to organizational performance, there is uncertainty and debate about what we know and don’t know. A review of the literature reveals that studies examining the association between information technology and organizational performance are divergent in how they conceptualize key constructs and their interrelationships. We develop a model of IT business value based on the resource-based view of the firm that integrates the various strands of research into a single framework. We apply the integrative model to synthesize what is known about IT business value and guide future research by developing propositions and suggesting a research agenda. A principal finding is that IT is valuable, but the extent and dimensions are dependent upon internal and external factors, including complementary organizational resources of the firm and its trading partners, as well as the competitive and macro environment. Our analysis provides a blueprint to guide future research and facilitate knowledge accumulation and creation concerning the organizational performance impacts of information technology.

Next-to-leading-order (NLO) QCD corrections to double J/psi production in e+e- annihilation at sqrt[s]=10.6 GeV are calculated. We find that they greatly decrease the cross section, with a K factor (NLO/LO) ranging from -0.31 to 0.25 depending on the renormalization scale. Although the renormalization scale dependence indicates a large uncertainty, when combined with the NLO QCD corrections to J/psi+etac production, it can explain why the double J/psi production could not be found at B factories while the J/psi+etac production could, despite the fact that cross section of the former is larger than that of the latter at LO by a factor of 1.8.
