A Simple Method for Completing Degenerate Delaunay

We characterize the conditions under which completing a Delaunay tessellation produces a connguration that is a nondegenerate Delaunay triangulation of an arbitrarily small perturbation of the original sites. One consequence of this result is a simple postpro-cessing step for resolving degeneracies in Delaunay triangulations that does not require symbolic perturbation of the data. We also give an example showing that if a set of points has a degenerate Delaunay tessellation, the globally equiangular triangulation is not necessarily realizable as the nondegenerate Delaunay triangulation of a perturbation of the sites.
A Topology Matching Method of Peer-to-Peer in the Mobile Environment

Peer-to-peer constructed on the basis of the distributed hash table don't consider the underlying physical network topology when it build logical overlay, which lead to topology mismatch. In the mobile environment, nodes move randomly, join and leave frequently, which have exacerbated the underlying physical network topology dynamic changes, and further exacerbated mismatch between the logical overlay and the underlying physical network. This paper propose several novel strategies, which includes dividing the P2P coverage into several regions and giving the node identifiers common prefix in the same region, classifying nodes' type according to the structure of physical network and node's moving characteristics under mobile environment, transforming the region of the nodes which move cross-regional and making node replacement when nodes join in or withdraw. All of these enhance the degree of matching overlay network to the physical network. Performance analysis shows that the method have significant advantages in transmission delay and search resources.
The dynamics of textile firm responses to the restriction of endocrine disrupting surfactants: a Vietnam case study

Abstract Since textile industry has been claimed to endanger the environment and human health, the insight of textile firm behavior regarding chemical use and discharge is vital for designing environmental risk management strategies. This study aimed to explore the dynamics of responses to the restriction of nonylphenol (NP) and its ethoxylates (NPEOs) among the Vietnamese textile manufacturers from the perspectives of attitude and the perceptions of adaptabilities, risks, benefits, and barriers. The chemicals are used as surfactants and are known to be responsible for endocrine disrupting effects. In-depth interviews were conducted with technical specialists from four textile firms and one chemical supplier. Regulatory and market situations with regards to the chemicals were also assessed. The findings revealed varied responses to chemical elimination where perceived technical risk, financial risk, benefits, and barriers played different roles in driving a certain action. The attitude towards chemical restriction was shaped by the trade-off between perceptions of financial risk and benefits and was moderated by market strategy. Efforts, such as enhanced washing or reductions in the dose of NP/NPEOs, imply the potency of continuous discharge of these chemicals into the environment, suggesting critical investigations on NP/NPEOs removal to prioritize actions for balancing between economic growth and environmental protection. Poor access to new policies and technological and chemical innovations was the most important barrier among private firms, highlighting the roles of non-governmental textile and garment industrial/trade associations in enhancing their members’ informative capacity. The study reflects the significance of incorporation of firm behavior research into environmental risk management practice.
Did Supermassive Black Holes Form by Direct Collapse

Rapid infall of gas in the nuclei of galaxies could lead to the formation of black holes by direct collapse, without first forming stars. Black holes formed in this way would have initial masses of a few M⊙, but would be embedded in massive envelopes that would allow them to grow at a highly super‐Eddington rate. Thus, seed black holes as large as 103–104 M⊙ could form very rapidly. I will sketch the basic physics of the direct collapse process and the properties of the accreting envelopes.
Non-contact, real-time monitoring of heart rate with a Webcam with application during water-bed massage

Techniques for measuring physiological signals are gathering a lot of attention in recent years. In many cases, the techniques require to make direct contact between the physiological signal sensors with the subject's skin. Several studies were proposed to measure heart rate (HR) with standard web cameras under the condition that the subject is keeping the quiescent state. In this paper, we propose a new technique for measuring HR which allows the subject head movements during water-bed massage. For comparison purpose, HR was measured simultaneously using an electrocardiography (ECG) device during all sessions of the experiment. The result shows that our proposed technique is able to improve the accuracy of HR measurement and reduce the processing time to nearly one-third of the existing method. Our approach could be beneficial for applications that require real-time HR monitoring during subject's head is moving.
Energy-Efficient Resource Provisioning with SLA Consideration on Cloud Computing

Cloud computing aims at reducing energy consumption and maximizing resource efficiency without violating service level agreement (SLA). To address these important issues, this study proposes an energy-efficient resource provisioning technology with SLA consideration for virtual machine scheduling. According to SLAs, the resource manager could consolidate virtual machines onto the physical machine for meeting customers SLA requests. Experimental results show that the proposed approach outperforms other proposed ones in power consumption.

Analysis and Optimisation of Distributed Embedded Systems with Heterogeneous Scheduling Policies

The growing amount and diversity of functions to be implemented by the current and future embedded applications (like, for example, in automotive electronics) have shown that, in many cases, time-triggered and event-triggered functions have to coexist on the computing nodes and to interact over the communication infrastructure. When time-triggered and event-triggered activities have to share the same processing node, a natural way for the execution support can be provided through a hierarchical scheduler. Similarly, when such heterogeneous applications are mapped over a distributed architecture, the communication infrastructure should allow for message exchange in both time-triggered and event-triggered manner in order to ensure a straightforward interconnection of heterogeneous components. This thesis studies aspects related to the analysis and design optimisation for safety-critical hard real-time applications running on hierarchically scheduled distributed embedded systems. It first provides the basis for the timing analysis of the activities in such a system, by carefully taking into consideration all the interferences that appear at run-time between the processes executed according to different scheduling policies. Moreover, due to the distributed nature of the architecture, message delays are also taken into consideration during the timing analysis. Once the schedulability analysis has been provided, the entire system can be optimised by adjusting its configuration parameters. In our work, the entire optimisation process is directed by the results from the timing analysis, with the goal that in the end the timing constraints of the application are satisfied. The analysis and design methodology proposed in the first part of the thesis is applied next on the particular category of distributed systems that use FlexRay as a communication protocol. We start by providing a schedulability analysis for messages transmitted over a FlexRay bus, and then by proposing a bus access optimisation algorithm that aims at improving the timing properties of the entire system. For all the problems that we investigated, we have carried out extensive experiments in order to measure the efficiency of the proposed solutions. The results have confirmed both the importance of the addressed aspects during system-level design, and the applicability of our techniques for analysing and optimising the studied systems.
Memristor-based multilevel memory

A method to utilize the memristor as a multilevel memory has been proposed. There are several roadblocks in the practical use of memristors for multilevel memory. A difficulty comes from the nonlinearity in the ¿ vs. q curve which makes it difficult to determine the proper pulse width for desired resistance values. Another one comes from the property of the memristor which integrates any kind of signals including noise that appeared at the memristor and causes memristors to be perturbed from their original values. The proposed method enables the memristor to be used as multilevel memory using a reference resistance array by forcing the memristor to stick at a set of predetermined fixed reference resistance values. We propose the write-in (programming) circuit and the readout/restoration circuit which share the information storing technique using the reference resistance array.
Motion Edit with Collision Avoidance

The existing motion editing methods don't take collision between the limbs into account potentially producing implausible motions. Facing this problem, in this paper we present an integrated framework of motion editing for producing collision-free motion in real-time. We first provide an efficient scheme for collision detection based on skeleton model, which can fast find the penetration between limbs of human body. Then we provide a novel scheme for constraint generation, which embeds the motion characteristics and inter-frame coherency into the constraint generator, and preserves the qualities of the original motion and motion consistency in the target motion. Finally, we show how to apply the Kalman filter to constraint resolve in a real-time manner. Comparing to other existing methods, our method not only can obtain the collision-free motion in real time, but also can preserve the original characteristics as many as possible and generate the new motion similar to the original motion. Experiment shows that our approach is very useful in producing natural and collision-free motion and efficient enough for application in animation system and game.
Greenhouse Gas Induced Changes in the Seasonal Cycle of the Amazon Basin in Coupled Climate-Vegetation Regional Model

Previous work suggests that changes in seasonality could lead to a 70% reduction in the extent of the Amazon rainforest. The primary cause of the dieback of the rainforest is a lengthening of the dry season due to a weakening of the large-scale tropical circulation. Here we examine these changes in the seasonal cycle. Under present day conditions the Amazon climate is characterized by a zonal separation of the dominance of the annual and semi-annual seasonal cycles. This behavior is strongly modified under greenhouse warming conditions, with the annual cycle becoming dominant throughout the Amazon basin, increasing differences between the dry and wet seasons. In particular, there are substantial changes in the annual cycle of temperature due to the increase in the temperature of the warmest month, but the lengthening of the dry season is believed to be particularly important for vegetation-climate feedbacks. Harmonic analysis performed to regional climate model simulations yields results that differ from the global climate model that it is forced from, with the regional model being more sensitive to changes in the seasonal cycle.
Idempotent Task Cache System for Handling Intermediate Data Skew in MapReduce on Cloud Computing

A MapReduce system gradually becomes a popular platform for developing cloud applications while MapReduce is the de facto standard programming model of the applications. However, a MapReduce system may suffer intermediate data skew to degrade performances because input data is unpredictable and the Map function of the application may generate different quantities of intermediate data according to the application algorithm. A MapReduce system can use the Idempotent Task Cache System (ITCS) proposed in this paper to handle intermediate data skew. A MapReduce system can avoid negative performance impacts of intermediate data skew with ITCS by using caches to skip the high workload of processing skewed intermediate data in certain Reduce tasks. In experiments, a MapReduce system is tested with several popular applications to prove that ITCS not only alleviates performance penalties when intermediate data skew happens, but also greatly outperforms native MapReduce systems without any help of ITCS.
Functional role of NF-IL6β and its sumoylation and acetylation modifications in promoter activation of cyclooxygenase 2 gene

NF-IL6β regulates gene expression and plays function roles in many tissues. The EGF-regulated cyclooxygenase-2 (cox-2) expression is mediated through p38MAPK signaling pathway and positively correlates with NF-IL6β expression in A431 cells. NF-IL6β coordinated with c-Jun on cox-2 transcriptional activation by reporter and small interfering RNA assays. NF-IL6β could directly bind to CCAAT/enhancer-binding protein (C/EBP) and cyclic AMP-response element (CRE) sites of the cox-2 promoter by in vitro-DNA binding assay. The C/EBP site was important for basal and, to a lesser extent, for EGF-regulated cox-2 transcription, while the CRE site was a more specific response to EGF inducibility of cox-2 gene. SUMO1 expression attenuated EGF- and NF-IL6β-induced cox-2 promoter activities. NF-IL6β was found to be sumoylated by in vivo- and in vitro-sumoylation assays, and the SUMO1-NF-IL6β (suNF-IL6β) lost its ability to interact with p300 in in vitro-binding assay. NF-IL6β was also acetylated by p300, and acetylation of NF-IL6β enhanced the cox-2 promoter activity stimulated by NF-IL6β itself. In vivo-DNA binding assay demonstrated that EGF stimulated the recruitment of p300 and NF-IL6β to the cox-2 promoter, yet promoted the dissociation of SUMO1-modificated proteins from the promoter. These results indicated that NF-IL6β plays a pivotal role in the regulation of basal and EGF-induced cox-2 transcription.
EFFECTS OF INNOVATION ON THE FIRM PERFORMANCE

This study was prepared by Stefan Lachenmaier while he was working with the Ifo Institute for Economic Research. It was completed in March 2007 and was accepted as a doctoral thesis by the Economics Department of the University of Munich (LMU). The subject of this study is an econometric analysis of the effects of innovation on firm performance. The main data source for this analysis is the Ifo Innovation Survey, which has provided yearly, firm-level data on innovation since 1982. Following two introductory chapters on innovation, the data set is introduced and explained in detail. Subsequent chapters analyze the effects of different types of innovation on four measures of firm performance, viz. sales, labor productivity, employment and exports. The econometric approach addresses the problems of unobserved firm heterogeneity as well as the potential endogeneity of innovation with respect to firm performance and its dynamics. Taken together, the results indicate that innovations show positive effects on sales, labor productivity and employment; the effects on exports are less clear.
The Impact of Innovation Activities on Employment in the Environmental Sector – Empirical Results for Germany at the Firm Level

Summary The paper explores employment effects of environmental product innovations at the firm level. Whereas there are many studies analysing this relationship for general innovations, studies for the environmental sector are still rare.On the background of high political attention connected with hopeful employment perspectives, a separate analysis of this sector in comparison to other, non-environmental fields seems to be very important. The empirical analysis is based on the establishment panel of the Institute for Employment Research (Nuremberg). The econometric results show that the influence of environmental innovation activities on the employment development is significantly positive and the quantitative impact seems to be larger than in other, non-environmental fields. Within a bivariate probit model, the determinants of environmental innovation activities are also explored. They may be interpreted as indirect influences on the employment development of the firm. The results show that the improvement of the innovative capacities by R&D and further education measures and the existence of highly qualified human capital are significantly important for the development of new products in the environmental sector
PIDS: a privacy intrusion detection system

It is well‐known that the primary threat against misuse of private data about individuals is present within the organisation; proposes a system that uses intrusion detection system (IDS) technologies to help safeguard such private information. Current IDSs attempt to detect intrusions on a low level whereas the proposed privacy IDS (PIDS) attempts to detect intrusions on a higher level. Contains information about information privacy and privacy‐enhancing technologies, the role that a current IDS could play in a privacy system, and a framework for a privacy IDS. The system works by identifying anomalous behaviour and reacts by throttling access to the data and/or issuing reports. It is assumed that the private information is stored in a central networked repository. Uses the proposed PIDS on the border between this repository and the rest of the organisation to identify attempts to misuse such information. A practical prototype of the system needs to be implemented in order to determine and test the practical feasibility of the system. Provides a source of information and guidelines on how to implement a privacy IDS based on existing IDSs.
Ordinal representations for biometrics recognition

Biometrics provides a reliable method for automatic personal identification and has wide and important applications. The success of a biometric recognition system depends critically on its feature representation model for biometric patterns. The most challenging issue in biometric feature representation is to achieve sensitivity to inter-class differences and at the same time robustness against intra-class variations. Many biometric representation schemes have been reported but the above issue remains to be resolved. In this paper, we introduce ordinal measures for iris, face and palmprint image representation in an attempt to resolve this issue. With this so-called ordinal representation model in place, many best-performing biometric recognition methods may be interpreted as special cases of this model. In this sense, the proposed ordinal representation model forms a general framework for biometric pattern representation. Extensive experimental results on public biometric databases demonstrate the effectiveness and generality of this representation.
A proposed unified terminology of species traits in stream ecology

Traits-based community analyses are receiving increasing attention. However, consistent interpretation of empirical results and ecological understanding in stream ecology are limited by ambiguous terminology. Furthermore, the measurement scales used to analyze trait data, especially ordinal-scale data, are often inappropriately applied. We identify and discuss these shortcomings and offer a solution for an operative and algebraically correct treatment of traits and a unified nomenclature that facilitates direct comparison among traits-based studies. A unified terminology allows for logical translation among existing, alternative trait nomenclatures and should facilitate communication of research findings among stream ecologists and more directly connect stream traits-based research with general ecology.
Cooperative Dual-Hop Relaying Systems with Beamforming over Nakagami-m Fading Channels

In this paper, we investigate the end-to-end performance of dual-hop relaying systems with beamforming over Nakagami-m fading channels. Our analysis considers semi-blind (fixed-gain) relays with single antennas, and source and destination nodes equipped with multiple antennas. Closed-form expressions for the outage probability (OP), moment generating function (MGF), and generalized moments of the end-to-end signal-to-noise ratio (SNR) are derived. The proposed expressions apply to general operating scenarios with distinct Nakagami-m fading parameters and average SNRs between the hops. The influence of the power imbalance, fading parameters, and antenna configurations on the overall system performance are analyzed and discussed through representative numerical examples. Furthermore, the exactness of our formulations is validated by means of Monte Carlo simulations.
Elderly Fallers Enhance Dynamic Stability Through Anticipatory Postural Adjustments during a Choice Stepping Reaction Time

In the case of disequilibrium, the capacity to step quickly is critical to avoid falling in elderly. This capacity can be simply assessed through the choice stepping reaction time test (CSRT), where elderly fallers (F) take longer to step than elderly non-fallers (NF). However, the reasons why elderly F elongate their stepping time remain unclear. The purpose of this study is to assess the characteristics of anticipated postural adjustments (APA) that elderly F develop in a stepping context and their consequences on the dynamic stability. Forty-four community-dwelling elderly subjects (20 F and 24 NF) performed a CSRT where kinematics and ground reaction forces were collected. Variables were analyzed using two-way repeated measures ANOVAs. Results for F compared to NF showed that stepping time is elongated, due to a longer APA phase. During APA, they seem to use two distinct balance strategies, depending on the axis: in the anteroposterior direction, we measured a smaller backward movement and slower peak velocity of the center of pressure (CoP); in the mediolateral direction, the CoP movement was similar in amplitude and peak velocity between groups but lasted longer. The biomechanical consequence of both strategies was an increased margin of stability (MoS) at foot-off, in the respective direction. By elongating their APA, elderly F use a safer balance strategy that prioritizes dynamic stability conditions instead of the objective of the task. Such a choice in balance strategy probably comes from muscular limitations and/or a higher fear of falling and paradoxically indicates an increased risk of fall.
