Boiling Pure Fluids at Sub Atmospheric Pressures

The study and sizing of sorption machine evaporators are based on the prediction of the heat transfer coefficient at atmospheric pressures, but in the literature we only find correlations modeled from experiments for a wide range of pressure, where the majority of the data are above atmospheric pressure; A review of the experiments of boiling at sub-atmospheric pressures was carried out and compared to four known correlations for three types of fluids, which are water, hydrocarbons and refrigerants; The results obtained showed deviations of the predicted data from the experimental values for three correlations and convincing results for the fourth.
Tip Loss Correction for Actuator/Navier–Stokes Computations

A new tip loss correction, initially developed for 1D Blade Element/Momentum (BEM) computations (submitted to Wind Energy), is now extended to 2D Actuator Disc/Navier-Stokes (AD/NS) computations and 3D Actuator Line/Navier-Stokes (AL/NS) computations. In the paper, it is shown that the tip loss correction is an important and necessary step for actuator/Navier-Stokes models. Computed results are compared to experimental data and to results from BEM computations using the new tip correction as well as the original one of Glauert (Aerodynamic Theory, Dover, New York, Chap. VII, Div. L, pp. 251-268). From the results it is concluded that the tip loss correction has been correctly employed in the Navier-Stokes based actuator models. The results also demonstrate that the difference between actuator line and actuator disk-based models may increase, especially for flows at a low tip speed ratio. Since the flows at a low tip speed ratio are too far to be considered as axisymmetrical flows, the actuator disk models that are based on axisymmetrical flow behaviors may not be valid.
Constrained optimization strategies and CAM software for single-pass peripheral milling

Abstract Constrained optimization strategies and computer flow charts for single-pass rough peripheral milling on NC/CNC and conventional machine tools are presented and discussed. Various practical machine tool constraints have been considered, namely the maximum available power, torque and feed force and feed speed and cutting speed limits. The optimization strategies for this common operation have been found to be very complex and require computer assistance. A comparison of handbook recommended and optimal solutions has highlighted the significant benefits of using the latter and the need for minimizing the component loading time and cost to maximize such benefits.
Neuroprotective Effects of Panax Notoginseng Saponins against Cerebral Ischemia via Improving Glutamate Metabolism Pathway: In Vivo and In Vitro

Background: Ischemic stroke patients suffer from relatively limited treatment options. Studies have shown that glutamate is the most important excitatory neurotransmitter in the central nervous system. However, excessive glutamate in the extracellular cause cell apoptosis, and neurodegenerative processed after cerebral ischemia stroke. Glutamate metabolism pathway is necessary for glutamate clearance after ischemic stroke. Here we investigated the in vivo and in vitro effects of Panax Notoginseng Saponins (PNS) on glutamate metabolism pathway. Methods: we used mice impaired by middle cerebral artery occlusion (MCAO) and astrocytes exposed to oxygen-glucose deprivation/ reoxygenation (OGD/R) to test the potential mechanism of PNS. In vivo, we determined the cerebral infarction volume and measured brain water content. In vitro, we measured the astrocytes viability and evaluated the morphology of astrocyte. In addition, glutamate uptake, Na+-K+-ATPase activity, the expression levels of glutamate transporter GLT-1 and glutamine synthetase (GS) were determined in vivo and in vitro. Results: In vivo, we demonstrated that PNS could significantly decrease cerebral ischemia injury and improve neurological function in mice impaired by MCAO. In vitro, we found that PNS increased astrocytes viability, inhibited LDH leakage, and improved morphology of astrocytes under OGD/R. Additionally, we reported that both in vivo and in vitro, PNS enhanced the glutamate uptake and Na+-K+-ATPase activity, and up-regulated the expression levels of glutamate transporter GLT-1 and GS. Conclusion: this study suggested that PNS protects against cerebral ischemia induced brain damage. The possible mechanism is related with inhibiting glutamate accumulation by improving glutamate metabolism pathway.
Compact designs of a shorted triangular patch antenna with a V slot

The compact designs of a shorted triangular patch antenna embedded with a V slot are proposed and studied. A broadband V‐slotted triangular patch antenna with one shorting wall is initially constructed as a reference. By inserting an additional shorting wall to this reference antenna, a new broadband operation can be obtained and its operating frequency is decreased by 22%, which corresponds to a reduction of 40% in the antenna area. The antenna area can be further reduced by symmetrically halving the patch size, and it is found that the impedance bandwidth of the broadband operation demonstrated no obvious variation and the operating frequency is only increased by around 8%. Details of the antenna designs and obtained results are presented. © 2006 Wiley Periodicals, Inc.

Research on Aeroelasticity Phenomenon of a Flat Copper Alloy Plate

Aeroelasticity is a science to study interaction between aerodynamic, elastic and inertial forces. Flutter is the most dangerous aeroelasticity phenomena, that is defined as the dynamic instability of an object in an airstream. Following flutter phenomenon, unsteady aerodynamic forces generated from elastic deformations of structure. It can lead to a disastrous structural failure. This paper examined aeroelasticity properties of a flat copper alloy plate by combining simulation methods using ANSYS software and experimental methods with help of subsonic wind tunnel at M = 0.1. At the first stage, elastic properties of this thin plate were carried out by using vibrational experiments and modal method to determine the specific vibration frequencies. Then, these aeroelasticity properties were estimated at three different attack angles of 0o, 5o and 10o. Finally, instability phenomenon of this flat plate was investigated within limited experimental conditions to be able to select objects and experimental solutions to be feasible and effective.
Theory of Reasoned Action

The approximately 60 million members of Generation Y are a major force in the consumer marketplace and represent a significant behavioral shift. To develop the broad, multifaceted advertising strategy necessary to reach them, more information is needed to characterize their purchase intentions. This study determines whether the theory of reasoned action can be used as a prediction tool in examining the purchase intention of a selected consumer group and product, Generation Y consumers and fashion merchandise made of emu leather. Respondents' attitudes significantly influenced their purchase intention: The more favorable the respondent's attitude, the higher the purchase intention. Subjective norm and other external variables had no influence on this group's purchase intention. The results partially support the theory of reasoned action as a prediction tool in examining purchase intention of a consumer product. This information is important to the emu leather industry, which may want to target Generation Y consumers.
An insightful analysis of the hybrid insulated-gate bipolar transistor

The shorted-anode or hybrid insulated-gate bipolar transistor (HIGBT) is examined theoretically (using a first-order analysis) and experimentally (using specially designed test structures) to give physical insight regarding the unique electrical properties of this power switching device. Basic differences between the HIGBT and the conventional lateral IGBT reflected by measurements of on-state conductance, transient turn-off time, and latchup current are explained and shown to be critically dependent on the structural geometry of the device. Also, a previously unacknowledged mode of operation of the HIGBT is demonstrated. >

Differential Expression of Long Noncoding RNAs in Patients with Coronary Artery Disease

Long noncoding RNAs (lncRNAs) constitute the largest class of noncoding RNAs and play significant roles in the development of cardiovascular pathologies. In the present study, we aimed to evaluate whether 4 candidate lncRNAs – MIAT, MEG3, MALAT1, and MCM3AP-AS1 – have distinct expression levels in patients with obstructive coronary artery disease (CAD) and reveal the diagnostic and therapeutic potentials of these lncRNAs for CAD. A total of 90 patients who subjected to coronary angiography were enrolled. Relative expression of lncRNAs were assayed using qRT-PCR methodology. As a result, MIAT was downregulated, while MEG3 was upregulated in CAD patients. Receiver operating characteristic curves demonstrated that these lncRNAs have a high potential to provide sensitive and specific diagnosis of CAD. The calculated area under curve levels indicated that MIAT and MEG3 have high diagnostic value for detecting the presence of significant CAD. However, MALAT1 and MCM3AP-AS1 levels were not sufficiently reliable for CAD development in our cases. Here, we demonstrate that MIAT and MEG3 were differentially expressed in our patients and might be promising biomarkers and therapeutic targets for CAD. These results indicate that MIAT and MEG3 could play chief roles in CAD development.
Management of networks involving Technology Transfer from public to private sector: a conceptual framework

Over recent decades, increasingly complex networks have emerged among universities, industries and governments involved in technology transfer from public to private sector. Despite the growing international importance of such networks, academic research examining the key management factors leading to their effectiveness is still sparse. This exploratory study investigates such network management factors in various industries in Australia. Based on interviews held with members from university, industry and government, we provide an analysis from a network-level perspective. Findings are used to develop a conceptual framework concerned with managing networks involving technology transfer from public to private sector.
The Effects of Field-of-View on Pilot Head Movement during Low Level Flight

Helmet mounted displays are being considered for a variety of uses in military aviation including training, mission rehearsal, and as a primary flight display in the cockpit. There is a need for considerable research into issues related to the use of this technology and the effects on pilot performance, particularly with respect to spatial orientation. One critical issue is the field-of-view (FOV) necessary when flying military aircraft. The purpose of this research was to investigate the effects of FOV on pilot head movement. Head tilt, pitch, and yaw data were collected in a dome simulator during a low level VMC flight task under three FOV conditions (40, 60, and 100 degrees). Results indicated that pilots exhibited reflexive head tilt movements (Opto Kinetic Collic Reflex) regardless of FOV. Head pitch and yaw varied as a function of FOV. Pilots made significantly more downward pitch movements with the 40-degree FOV over a wider range of aircraft bank. Head yaw was more prevalent as FOV decreased.
The Economics of Online Television: Revenue Models, Aggregation, and 'TV Everywhere'

Unlike most media, the U.S. television industry has continued to prosper as broadband diffusion has grown to reach over 2/3 of households. We first identify the source of standard TV’s long term prosperity: technology, especially digital conversion. The result has been a massive shift since the 1970s from advertising to direct pay support, and greatly increased quality and variety of television programs-- in turn leading to ever-higher TV usage. Since about 2000, online video streaming has become widespread, but its overall proportion of all TV viewing remains under 2%. Focusing on professionally produced commercial TV products, we find that online TV has also shifted toward a direct pay revenue model, and we offer suggestive evidence that online distribution is cheaper and more efficient than MVPD distribution. We attribute the apparent dominance of aggregators in online TV distribution to economic efficiencies. Drawing on a taxonomy of “Everywhere TV” systems marketed by the top 25 MVPDs, we model these “authentication” tie-ins as price discrimination devices intended to slow MVPD disconnections; although in plausible circumstances, the price discrimination incentive can slow development of online TV. Anti-competitively motivated behavior by established MVPDs or ISPs is also plausible, but while facilitated by vertical integration into program supply, the viability of anti-competitive strategies ultimately depends on large national market shares of the MVPD and ISP markets to be effective. Note: A set of slides presented by David Waterman at National Chengchi University in Taipei, Taiwan on March 29, 2012 offers a preliminary outline for the analysis now underway in support of this paper.
Unmanned Aircraft System (UAS) Delegation of Separation in NextGen Airspace

The purpose of this study was to determine the feasibility of unmanned aircraft systems (UAS) performing delegated separation in the national airspace system (NAS). Delegated separation is the transfer of responsibility for maintaining separation between aircraft or vehicles from air navigation service providers to the relevant pilot or flight operator. The effects of delegated separation and traffic display information level were collected through performance, workload, and situation awareness measures. The results of this study show benefits related to the use of conflict detection alerts being shown on the UAS operator's cockpit situation display (CSD), and to the use of full delegation. Overall, changing the level of separation responsibility and adding conflict detection alerts on the CSD was not found to have an adverse effect on performance as shown by the low amounts of losses of separation. The use of conflict detection alerts on the CSD and full delegation responsibilities given to the UAS operator were found to create significantly reduced workload, significantly increased situation awareness and significantly easier communications between the UAS operator and air traffic controller without significantly increasing the amount of losses of separation.

Human-Computer Interaction: Developing Effective Organizational Information Systems

This book is about developing interactive information systems that support people at work or when conducting business. Specifically, it emphasizes the need to study and practice the development of HCI for real-world organizations in given contexts. Developing an effective information system means achieving a good fit among the users. In order to do this, designers need to have a good understanding of important factors that come into play. Designers need to understand why and how people interact with computers in order to accomplish their work and personal goals, what are the physical, cognitive, affective and behavioral constraints on the users’ side what pleases or annoys them, what makes human-computer interaction a satisfying experience or an effective. This knowledge is the foundation of human-computer interaction (HCI) development.
Differentiating terrorist groups: a novel approach to leverage their online communication

ABSTRACT Any intervention in the violent acts of terrorist groups requires accurate differentiation among the groups themselves, which has largely been overlooked in their study beyond qualitative work. To explore the notion of terrorist group differentiation, the online communication of six violent groups were collected: Al-Nusrah Front, al-Qa’ida Central, al-Qa’ida in the Arabian Peninsula, Hamas, Islamic State of Iraq and Syria, and Taliban. All six groups embedded their ideology in digitised documents that were shared through multiple online social networks and media platforms in attempts to influence individuals to identify with their beliefs. The way these groups constructed social roles for their supporters in their ideology was proposed as a novel way to differentiate them and key term extraction was used to find important terms referenced in their communication. Experimental classification was devised to find the highest-ranking roles capable of prediction. Role terms produced high accuracy scores across experiments differentiating the groups (95%CI: 95–98%), with varying inter-group and intra-ideological differences emerging from authority-, religion-, closeness-, and conflict-based social roles. This suggests these constructs possess strong predictive potential to separate terrorist groups through nuanced expressions observed in their communication behaviour and advances our understanding of how these groups deploy harmful ideology.
Biocell Application Guidance

Abstract : Biocell technology is an innovative method for treating small quantities of soils contaminated with low to intermediate concentrations of petroleum hydrocarbons, which are usually found on Navy installations. The technology involves loading petroleum-contaminated soils into a dumpster or container, and stimulating aerobic microbial activity through aeration. Adding moisture and nutrients, such as nitrogen and phosphorus, enhances microbial activity. The microbial activity degrades the petroleum-based constituents adsorbed to soil particles, thus reducing the concentrations of these contaminants. The use of biocells to reduce the concentration of petroleum constituents in excavated soils through the use of aerobic biodegradation has been successfully demonstrated. The Army's Waterways Experiment Station (WES) developed a 10-yd(3) biocell that was tested at the Naval Construction Battalion Center, Port Hueneme, California in October 1996. A significant part of the WES research was aimed at simplifying the technology for an activity to build a 40-yd(3) system using readily available commercial materials. Based on WES's design and the successful demonstration of a 10-yd(3) biocell, NFESC has developed this document to provide Navy installations a general overview of the biocell technology, design, operation and maintenance procedures, and economics.
