A family of real‐time Java benchmarks
Authors: Kalibera Tomas , Hagelberg Jeff , Maj Petr , Pizlo Filip , Titzer Ben , Vitek Jan 
Published: November 2010

AbstractJava is becoming a viable platform for real‐time computing. There are production and research real‐time Java VMs, as well as applications in both the military and civil sectors. Technological advances and increased adoption of real‐time Java contrast significantly with the lack of benchmarks. Existing benchmarks are either synthetic micro‐benchmarks, or proprietary, making it difficult to independently verify and repeat reported results. This paper presents the CDx benchmark, a family of open‐source implementations of the same application that target different real‐time virtual machines. CDx is, at its core, a real‐time benchmark with a single periodic task, which implements an idealized aircraft collision detection algorithm. The benchmark can be configured to use different sets of real‐time features and comes with a number of workloads. It can be run on standard Java virtual machines, on real‐time and Safety Critical Java virtual machine, and a C version is provided to compare with native performance.

VoIP secure session assistance and call monitoring via building security gateway
Authors: Li Jung‐Shian , Kao Chuan‐Kai , Tzeng Jau‐Jan 
Published: November 2010

AbstractA secure architecture is proposed in the home/office networking environment with a special appliance, called Building Security Gateway (BSG), for cheap SIP devices and unsupported soft user agents (UAs) performing security functions successfully, such as construction of secure sessions and encrypting/decrypting media. Therefore, we apply BSG procedure to VoIP for getting secure session. Furthermore, VoIP call monitoring and intercepting functions are also implemented in BSG. Secure session monitoring is supported in this architecture. A prototype BSG is built in a home/office network, and BSG‐based session mobility cases between UAs are examined and the protocol primitives for security and call intercepting are verified.

TRASS: A transmission rate‐adapted streaming server in a wireless environment
Authors: Leu Jenq‐Shiou , Chen Sheng‐Fu 
Published: November 2010

AbstractThe video streaming quality in a wireless communication network environment is largely affected by various network characteristics, such as a limited channel bandwidth and a variant transmission rate. The playback quality of User Equipments (UEs) may not be smooth when the service is delivered via a wireless environment. From the viewpoints of most video receivers, a smooth playback with a lower video quality may be more significant than a lagged or distorted playback with a higher video quality as the transmission rate degrades. Based on the above, we sketch an adaptation agent—Transmission‐Rate Adapted Streaming Server (TRASS), which is located between the original video server and UEs, to adaptively transform the streaming video based on the real transmission rate. In our proposed scheme, UEs would feedback their network access statuses to TRASS and then TRASS would deliver adaptive quality of video streams to UEs according to their feedbacks. The theoretical analysis and simulations using different video tracks encoded in MPEG‐4 and H.264/AVC formats show that TRASS can help wireless streaming users to get a smooth playback quality with a lower packet failure rate. With a low probability of receiving a worse quality of video, users' Quality of Experience can subsequently be raised. Copyright © 2010 John Wiley & Sons, Ltd.
Atmospheric Pressure Chemical Vapour Deposition of TiCl4 and tBuAsH2 to Form Titanium Arsenide Thin Films
Authors: Thomas Tegan , Blackman Christopher S. , Parkin Ivan P. , Carmalt Claire J. 
Published: November 2010

AbstractTitanium arsenide thin films were deposited by the atmospheric‐pressure chemical vapour deposition (APCVD) of TiCl4 and tBuAsH2 at substrate temperatures between 450 and 550 °C. The deposited films are typically silver in appearance, demonstrate good adherence and were identified by X‐ray powder diffraction as crystalline TiAs. X‐ray photoelectron spectroscopy (XPS) and Raman microscopy support the formation of TiAs. The TiAs films have an approximate 1:1 ratio of Ti:As, as identified by wavelength dispersive analysis of X‐rays (WDX), and the films grow by an island growth mechanism with deposition rates of ca. 0.1 μm min–1. The films display borderline metallic/semiconductor conductivity and those deposited at 550 °C possess high hardness.
Detection of oxysterols in oxidatively modified low density lipoprotein by MALDI‐TOF MS
Authors: Hasegawa Masahiro , Hakamata Hideki , Matsunaga Io , Kusu Fumiyo 
Published: November 2010

AbstractA simple method for the detection of oxysterols in oxidatively modified LDL (Ox‐LDL) has been developed using MALDI‐TOF MS. To identify the ion peaks of oxysterols, seven major oxysterols in Ox‐LDL (7α‐hydroxycholesterol, 7β‐hydroxycholesterol, 7‐ketocholesterol, 5α,6α‐epoxycholesterol, 5β,6β‐epoxycholesterol, 25‐hydroxychokesterol, (25R)‐26‐hydroxycholesterol), and cholesta‐3,5‐dien‐7‐one were analyzed by MALDI‐TOF MS. Among these oxysterols, 7‐ketocholesterol, a very abundant oxysterol in Ox‐LDL, was found to show a characteristic peak of [M + H]+ at m/z 401. Cholesta‐3,5‐dien‐7‐one, which is known as a degradation product of 7‐ketocholesterol upon saponification of Ox‐LDL, gave a major peak of [M + H]+ at m/z 383. In contrast, other oxysterols showed similar peak patterns at m/z 367 and 385. These results were applied to the analysis of Ox‐LDL by MALDI‐TOF MS after saponification and hexane‐extraction, detecting ion peaks at m/z 367, 383, 385, and 401. This MALDI‐TOF MS method has a potential as a simple tool to show the presence of oxysterols in Ox‐LDL without derivatization and chromatographic separation.
Amperometric Determination of Chemical Oxygen Demand via the Functional Combination of Three Digestion Types
Authors: Zhang Aiyong , Zhou Minghua , Han Lu , Zhou Qixing 
Published: November 2010

AbstractThe study focused on the proposal and experimental validation of an combined photoelectrocatalytic principle for chemical oxygen demand determination (combined PeCOD, PeCOD‐combined), which was functionally comprised of photon‐efficient thin‐film photochemical, photocarrier‐efficient electrochemical and conventional bulk‐phase photochemical digestion types in one single photodigestion process. The combined PeCOD technology was proposed mainly on the basis of the significantly informative work of existing photoelectrocatalytic COD (thin‐layer PeCOD, PeCOD‐thin), and could realize the three different digestion types on one single rotating photoanode. The three important operation conditions of rotating speed, applied bias and pH value were investigated and optimized, and a wide analytical linear range of 2.7–11 500 mg/L was consequently obtained during an approximately 5–110 min determination period, and a real sample analysis further validated the practical feasibility of the proposed PeCOD‐combined. In PeCOD‐combined the main organics digestion and signal generation occurred via PeCOD‐thin due to efficient UV utilization and excellent photodigestion activity.

Published: November 2010

AbstractSelective electroanalytical responses for ascorbic acid, dopamine and uric acid at a carbon modified electrode based on 3‐n‐propyl‐1‐azonia‐4‐azabicyclo[2.2.2]octane silsesquioxane chloride (SiDbCl) is reported. The overlapped peaks observed at an unmodified electrode are resolved into three well defined voltammetric peaks allowing the simultaneous determination of the three species. Detection limits of 37, 0.3 and 0.1 μmo L−1 of ascorbic acid, dopamine and uric acid, respectively, were calculated from calibration curves based on differential pulse voltammetric experiments performed in Britton‐Robinson buffer solution at pH 7.04.
Looking for similar patterns among monitoring stations. Venice Lagoon application
Authors: Pastres R. , Pastore A. , Tonellato S. F. 
Published: November 2010

AbstractThe main purpose of this paper is to provide a classification, in terms of different trophic variables, of the sites of a water quality monitoring network located in Venice Lagoon. We apply a classification method based on functional data analysis (FDA), introduced by James and Sugar (2003), which allows to take into account sample information about the temporal dynamics of the variables of interest, as well as quantify the uncertainty in the partition. We found that classification based on FDA can provide useful insights to environmental scientists and public authorities with respect to the optimisation of monitoring networks and the identification of critical features deserving further investigation.

Prediction of pure‐component flash points for organic compounds
Authors: Rowley Jeffrey R. , Rowley Richard L. , Wilding W. Vincent 
Published: November 2010

AbstractPublished flash point prediction methods are evaluated for accuracy against experimental data from the DIPPR ® 801 database. The most accurate methods require a vapor pressure correlation, which is often not available. Two new methods are presented, one that uses the vapor pressure, and one based on the normal boiling point and enthalpy of vaporization at the normal boiling point. The vapor pressure method shows little improvement over the previous methods unless group contributions are implemented. The boiling point method predicts the flash point within an absolute average deviation of 1.3% when compared with data for more than 1000 compounds. The previous most accurate method that was not based on vapor pressure exhibited an absolute average deviation of 1.84% for the same test set. Copyright © 2010 John Wiley & Sons, Ltd.
Feasibility of reformulating flavours between food products using in vivo aroma comparisons
Authors: Yang Nicole , Linforth Robert S. T. , Walsh Stuart , Brown Keith , Hort Joanne , Taylor Andrew J. 
Published: November 2010

AbstractThe feasibility of reformulating a commercial flavouring using a simple predictive model was studied in two confectionery (candy) systems. Initially, the variation in the different stages of the reformulation process was quantified using a model flavour. MS‐Nose analysis showed variation between 1% and 3% for static headspace analyses (ethyl nonanoate showed 9% variation). Flavour content in the finished candies varied from 4% to 22%. Despite variation between panellists' aroma release (3–60%), data analysis indicated that representative aroma release could be obtained using five panellists consuming three replicates. For reformulation studies, a simple commercial strawberry flavouring was chosen that delivered a highly acceptable flavour in a pectin–sucrose gel, but did not perform so well in a chewy candy containing sugar, protein and fat. By measuring in vivo aroma profiles in people eating the gel and the chewy candy, the relative change in aroma release could be determined and used to reformulate the strawberry flavouring so its release in both candies was similar. The sensory performance of candies with the original and reformulated flavourings was measured using difference testing (n = 100) and descriptive analysis (n = 5). Both analyses indicated that the reformulated flavour performed significantly better than the original flavour. The work shows the translation of a laboratory‐based concept into the commercial world and provides another tool to assist flavourists in reformulating flavourings to deliver food products with the desired sensory properties.

Modelling ice–bed coupling during a glacier speed‐up event: Haut Glacier d'Arolla, Switzerland
Authors: Fischer Urs H. , Mair Doug , Kavanaugh Jeffrey L. , Willis Ian , Nienow Peter , Hubbard Bryn 
Published: November 2010

AbstractShort‐term increases in surface velocity have long been observed on alpine glaciers and more recently across the Greenland Ice Sheet. Alpine speed‐up events typically occur when the subglacial drainage system is unable to accommodate a sudden and large influx of water. The ensuing backup of water in the drainage system commonly leads to a rise in subglacial water pressure, local ice–bed decoupling and enhanced sliding. Through horizontal stress coupling, this locally induced high pressure forcing also increases glacier motion in regions adjacent to the decoupled regions by enhanced, non‐locally forced basal motion. These speed‐up events demonstrate the importance of subglacial hydromechanical adjustments for patterns of glacier flow. This article applies Kavanaugh and Clarke's (2006) numerical model, which simultaneously solves equations that describe the time‐evolution of subglacial sediment pore‐water pressure, bed deformation, glacier sliding and ice‐dynamical shear stress transfer, to Haut Glacier d'Arolla, Switzerland. Model input parameters are determined from field observations and interpretations of the basal hydrological system beneath the main glacier tongue and in particular during an approximate fivefold increase in surface velocity observed in June 1998 (Mair et al., 2003). Model output, in the form of synthetic subglacial instrument responses, is compared with signals recorded by instruments emplaced at the glacier bed. Sensitivity analyses demonstrate that while the model outputs are sensitive to input parameters, modelled sediment strength and shear strain rate responses show good agreement, in both magnitude and form, with values recorded in the field under specific realistic parameterizations. The qualitative agreement between measurements and modelled output suggests that the key assumptions regarding hydraulically induced changes in sediment strength, sediment deformation and basal shear stress distribution are sound.
