EVALUATION OF NETWORKED BASED ATTENUATION CORRECTION IN CASA IP-1 TESTBED

Monitoring of precipitation using higher frequency radar systems such as X-band is becoming popular. At X-band frequency, weather radar signals are attenuated along their paths due to precipitation. A network-based reflectivity retrieval technique has been developed for the Adaptive Sensing of the Atmosphere (CASA) system, which is a radar network that can observe a weather event simultaneously by multiple radars in different locations. In this paper the network based attenuation correction will be evaluated by CASA Integrated Project 1 (IP1) data during 20072009 field experiments. The results show that the networked based attenuation correction algorithm retrieves reflectivity properly. Index Terms — X band, Network, Attenuation correction, CASA IP1
WHAT'S INFORMATION, FOR AN ORGANISM OR INTELLIGENT MACHINE? HOW CAN A MACHINE OR ORGANISM MEAN?

Words and phrases referring to information are now used in many scientific and non-scientific academic disciplines and in many forms of engineering. This chapter suggests that this is a result of increasingly wide-spread, though often implicit, acknowledgement that besides matter and energy the universe contains information (including information about matter, energy and information) and many of the things that happen, including especially happenings produced by living organisms, and more recently processes in computers, involve information-processing. It is argued that the concept “information” can no more be defined explicitly in terms of simpler concepts than any of the other deep theoretical concepts of science can, including “matter” and “energy”. Instead the meanings of the words and phrases referring to such things are defined implicitly in part by the structure of the theories in which they occur, and in part by the way those theories are tested and used in practical applications. This is true of all deep theoretical concepts of science. It can also be argued that many of the pre-scientific concepts developed by humans (including very young humans) in the process of coming to understand their environment are also implicitly defined by their role in the theories being developed. A similar claim can be made about other intelligent animals, and future robots. An outline of a theory about the processes and mechanisms various kinds of information can be involved in is presented as partial implicit definition of “information”. However there is still much work to be done including investigation of varieties of information processing in organisms and other machines.
- 1-DYNAMIC PREDICTION MODEL FOR FINANCIAL DISTRESS IN CONSTRUCTION INDUSTRY USING DATA MINING

The early awareness of a potential financial distress is crucial to firm’s managers for understanding their clients, suppliers and their own firms, and crucial to fund suppliers for assessing the construction firm’s credit worthiness. The purpose of this paper is to develop a dynamic prediction model for financial distress in construction industry using Data Mining. This research expects to provide construction firm managers and creditors an effective index for evaluating the credit risk a construction firm. Results show that the proposed model has higher accuracy and stability for distress prediction and can provide a more effective quantitative framework for evaluating the financial standing of a construction firm.

Thermal-aware bus-driven floorplanning

As the number of buses in multi-core SoC designs increase, bus planning problems become a dominant factor in determining the chip performance. To cope with these issues, it is desirable to consider them in the early floorplanning stage. Recently, many bus-driven floorplanners have been proposed in the literature. However, those proposed algorithms only consider the bus planning problem without the thermal effect. As a result, there are hotspots which result in high chip temperature on the chip. In this paper, a thermal-aware bus-driven floorplanning algorithm is proposed to separate hotspots during the perturbation stage and to keep buses away from hotspots during the routing stage. To avoid time-consuming thermal simulations, the superposition of thermal profiles which are the thermal distribution of each module is adopted to efficiently estimate the module temperature. Compared with the state-of-the-art bus-driven floorplan-ner, experimental results demonstrate that the proposed algorithm can effectively separate hotspots and reduce the chip temperature.

The overblown implications effect.

People frequently engage in behaviors that put their competencies on display. However, do such actors understand how others view them in light of these performances? Eight studies support an overblown implications effect (OIE): Actors overestimate how much observers think an actor's one-off success or failure offers clear insight about a relevant competency (Study 1). Furthermore, actors overblow performances' implications even in prospect, before there are experienced successes or failures on which to ruminate (Studies 2 and 3). To explain the OIE, we introduce the construct of working trait definitions-accessible beliefs about what specific skills define a general trait or competency. When actors try to adopt observers' perspective, the narrow performance domain seems disproportionately important in defining the general trait (Study 4). By manipulating actors' working trait definitions to include other (unobserved) trait-relevant behaviors, we eliminated the OIE (Study 5). The final 3 studies (Studies 6a-6c) more precisely localized the error. Although actors and observers agreed on what a single success or failure (e.g., the quality of a single batch of cookies) could reveal about actors' narrow competence (e.g., skill at baking cookies), actors erred in thinking observers would feel this performance would reveal a considerable amount about the more general skill (e.g., cooking ability) and related specific competencies (e.g., skill at making omelets). Discussion centers on how the present theoretical account differs from previous explanations why metaperceptions err and identifies important open questions for future research.

The Ethical Landscape of Robotics

In this article, we highlight the possible benefits, as well potential threats, related to the widespread use of robots. We follow the view that a robot cannot be analyzed on its own without taking into consideration the complex sociotechnical nexus of today's societies and that high-tech devices, such as robots, may influence how societies develop in ways could not be foreseen during the design of the robots. In our survey, we limit ourselves to presenting the ethical issues delineated by other authors and relay their lines of reasoning for raising the public's concerns. We show that disagree ments on what is ethical or not in robotics stem often from different beliefs on human nature and different expectations on what technology may achieve in the future. We do not offer a personal stance to these issues, so as to allow the reader to form his/her opinion.
Hierarchical Mobile Wireless Network ( HMWN ) *

Ad hoc networks may not be suitable for “non ad hoc” applications due to resource, mobility, traffic pattern and incompatible wireless MAC protocols issues. We propose the Hierarchical Mobile Wireless Network for providing flexible and scalable network services to these applications. In such a system, mobile hosts are organized into hierarchical groups. Four basic operations that are used to set up and maintain the network structure are described. An efficient protocol for group membership management is discussed. The Segmented Membership-based Group Routing protocol is presented. In this routing protocol, only local message exchanging is required. Simulation-based experiments confirm the scalability of our design.
Typing and querying XML documents: some complexity bounds

We study the complexity bound of validating XML documents, viewed as labeled unranked ordered trees, against various typing systems like DTDs, XML schemas, tree automata . We also consider query evaluation complexities for various fragments of XPath. For both problems, validation and query evaluation, we consider data and combined complexity bounds.
On a homework problem of Larry Horn’s

Larry Horn is justifiably famous for his work on the semantics of the English conjunction or and both its relationship to the formal logic truth functions ∨ and @ (“inclusive” and “exclusive” disjunction respectively) and its relationship to the ways people employ or in natural discourse. These interests have been present since his 1972 dissertation, where he argued for a “scalar implicature-based” account of many of these relationships as opposed to a presuppositional account. They have surfaced in his “Greek Grice” paper (Horn 1973) as well as in his Negation book (Horn 1989) and his recent “Border Wars” paper (Horn, forthcoming) where he defends the position that there are two types of implicatures at work here: Qimplicatures based on Grice’s first maxim of Quantity (“Say Enough”) and R-implicatures based on Grice’s second maxim of Quantity (“Don’t Say Too Much”). In a nutshell, the idea is that when a speaker employs a sentence with a disjunction, the meaning (that is, the semantic value) of the or is inclusive. With careful and judicious use of the Qand R-implicatures, Larry’s theory allows the hearer (often) to infer that the speaker wanted to convey an exclusive disjunction.
Write Endurance in Flash Drives: Measurements and Analysis

We examine the write endurance of USB flash drives using a range of approaches: chip-level measurements, reverse engineering, timing analysis, whole-device endurance testing, and simulation. The focus of our investigation is not only measured endurance, but underlying factors at the level of chips and algorithms--both typical and ideal--which determine the endurance of a device. Our chip-level measurements show endurance far in excess of nominal values quoted by manufacturers, by a factor of as much as 100. We reverse engineer specifics of the Flash Translation Layers (FTLs) used by several devices, and find a close correlation between measured whole-device endurance and predictions from reverse-engineered FTL parameters and measured chip endurance values. We present methods based on analysis of operation latency which provide a non-intrusive mechanism for determining FTL parameters. Finally we present Monte Carlo simulation results giving numerical bounds on endurance achievable by any on-line algorithm in the face of arbitrary or malicious access patterns.
VOLTAGE SWITCHING TABLES FOR DIRECT TORQUE CONTROL OF PMSM DRIVE

Controlul direct în cuplu (DTC) este una dintre metodele de comandă care se bazează pe controlul în flux şi în cuplu. Dintre toate metodele de comandă a cuplului motorului sincron cu magnet permanent (PMSM), DTC ese cea care asigură un răspuns rapid şi robust al cuplului fără a folosi senzori de poziţie sau de viteză, transformarea de coordonate, generarea de pulsuri PWM şi regulatoare de curent. Această abordare propune o schemă de control în care cuplul electromagnetic şi valoarea fluxului rotoric sunt estimate numai cu ajutorul tensiunilor şi curenţilor. Estimarea nu depinde de parametrii motorului cu excepţia rezistenţei electrice a înfăşurării statorice. Articolul prezintă cercetările autorilor privind efectul vectorilor spaţiali de tensiune zero în sistemele DTC ale PMSM şi arată că, folosind raţional tensiunile zero, sistemele DTC pot fi comandate cu succes, iar variaţia cuplului este redusă semnificativ şi performanţa sistemului este îmbunătăţită. Eficienţa strategiei este analizată prin modelarea implementării şi folosirea unor tabele de comutaţie specifice pentru PMSM interior.
How Useful Is Relevance

Eliminating irrelevant attributes prior to induction boosts the performance of many learning algorithms. Relevance, however, is no guarantee of usefulness to a particular learner. We test two methods of finding relevant attributes, FOCUS and RELIEF, to see how the attributes they select perform with ID3/C4.5 on two learning problems from a calendar scheduling domain. A more direct attribute selection procedure, hillclimbing in attribute space, finds superior attribute sets.
Galaxy destruction and diffuse light in clusters

ABSTRACT Deep images of the Centaurus and Coma clusters reveal two spectacular arcs ofdiﬀuse light that stretch for over 100 kpc, yet are just a few kpc wide. At a surfacebrightness of m b ∼ 27−28th arcsec −2 , the Centaurus arc is the most striking exampleknown of structure in the diﬀuse light component of a rich galaxy cluster. We usenumerical simulations to show that the Centaurus feature can be reproduced by thetidal debris of a spiral galaxy that has been tidally disrupted by the gravitational po-tential of NGC 4709. The surface brightness and narrow dimensions of the diﬀuse lightsuggest that the disk was co-rotating with its orbital path past pericenter. Featuresthis prominent in clusters will be relatively rare, although at fainter surface bright-ness levels the diﬀuse light will reveal a wealth of structure. Deeper imaging surveysmay be able to trace this feature for several times its presently observed extent andsomewhere along the tidal debris, a fraction of the original stellar component of thedisk will remain bound, but transformed into a faint spheroidal galaxy. It should bepossible to conﬁrm the galactic origin of the Centaurus arc by observing planetarynebulae along its length with redshifts close to that of NGC 4709.Key words: galaxies: evolution – galaxies: clusters – galaxies: interactions – galaxies:formation.
Formulaic expressions in spontaneous speech of left‐ and right‐hemisphere‐damaged subjects

Background: The preservation of swearing, serial speech, and speech formulas is well documented in clinical descriptions of aphasia. Proper nouns and sentence stems have also been reported in the residual speech of severely aphasic subjects. The incidence of formulaic expressions in spontaneous speech of right‐hemisphere‐damaged subjects has not yet been well examined. Recent interest in formulaic expressions (FEs) in normal language use, combined with the converging evidence of a role for the right hemisphere in processing pragmatic elements of language, led to this study. Methods & Procedures: We undertook an examination of hypotheses about the hemispheric processing of FEs in the spontaneous speech of persons with left hemisphere (LH) and right hemisphere (RH) damage. Based on preserved use of formulaic expressions in clinically described aphasic speech, the hypothesis under examination in this study was that the intact RH has a role in the production of formulaic expressions. Further inquiries involved possible differences in incidence in the speech samples between subsets of FEs, such as proper nouns and discourse particles. Outcomes & Results: Our results indicate a greater proportion of FEs in the spontaneous speech of persons with LH damage, and proportionally fewer FEs in RH speech, when compared to normal control speakers. Examination of the incidence of separate categories indicates a paucity of proper noun production in the LH group, supporting the association of proper noun anomia with LH damage. Pragmatically determined vocal elements (pause fillers, discourse elements) were least present in RH dysfunction. These results suggest that clinical evaluation of formulaic as well as novel language functions may give important insights into the language disorder profile of various neurological populations. The identification of relatively preserved formulaic expressions in LH damage may provide a basis for a more effective treatment plan, while evaluation of RH damaged individuals using this perspective may identify communication disorders not previously recognised. Conclusions: These results support the notion that an intact RH supports use of some types of formulaic language.
Relationships between a new type IV secretion system and the icm/dot virulence system of Legionella pneumophila

We describe here a Legionella pneumophila type IV secretion system that is distinct from the previously described icm/dot system. This type IV secretion system contains 11 genes (lvh ) homologous to genes of other type IV secretion systems, arranged in a similar manner. The lvh genes were found to be located on a DNA island with a GC content higher than the L. pneumophila chromosome. In contrast to the icm/dot system that was shown to be required for intracellular growth in HL‐60‐derived human macrophages and Acanthamoeba castellanii, the lvh system was found to be dispensable for intracellular growth in these two hosts. The lvh system was found to be partially required for RSF1010 conjugation, a process that was previously shown to be completely dependent on several icm/dot genes. However, results obtained from analysis of double mutants in the icm/dot genes and the lvh genes revealed that lvh genes can substitute for some components of the icm/dot system for RSF1010 conjugation, but not for intracellular growth. These results indicate that components of the icm/dot system and components of the lvh type IV secretion system are able to interact with one another.
A taxonomy of software visualization

Software visualization is the use of interactive computer graphics, typography, graphic design, animation, and cinematography to enhance the interface between the software engineer or the computer science student and their programs. Although several taxonomies of software visualization have been proposed, they use few dimensions and do not span the space of important distinctions between systems. The authors propose a novel and systematic taxonomy of six areas making up thirty characteristic features of software visualization technology. The taxonomy is presented and illustrated in terms of its application to seven systems of historic importance and technical interest. <<ETX>>
Context-Based Information Provision from External Sources

This paper addresses the context-based information provision from external sources in intelligent environments. The overall goal is to assist people by exploring the content, linking new information to their own knowledge, and providing related information. Therefore, we investigate the entire process: a) identifying the users information need, b) collecting the needed information, and c) displaying the collected information. First, we examine methods to recognize the users information needs. We then illuminate the various external information sources with their great amount of diverse information types. Due to the high variety of external sources, we focus on scientific publications. The objective is to provide adequate scientific publications related to the context within the intelligent environment. The investigation described here also requires to consider privacy issues. We depict the selection of the displaying device.
Event-Based Networked Islanding Detection for Distributed Solar PV Generation Systems

This paper proposes an event-based networked set-membership filtering method to detect islanding fault for distributed grid-connected solar photovoltaic generation systems. The method enables each set-membership filter to offer an ellipsoidal estimation set, which is used to judge whether or not the islanding fault happens. When islanding fault happens, the intersection of the ellipsoids is empty, and when islanding fault is free, the intersection of the ellipsoids is nonempty. In the filtering scheme, a novel event-triggered mechanism is proposed to reduce the transmission frequency for saving the communication resources. The condition of the existence of the set-membership algorithm is derived by a time-varying convex optimization approach. A simulation experiment and a comparative experiment are provided using Sim-Power-Systems implementation based on a 2-kW single-phase grid-connected power generation system to illustrate the effectiveness of the proposed method for the detection of the islanding fault and the reduction of the resource consumption, respectively.
Smooth sparse representation for noise robust face super-resolution

Face super-resolution has attracted much attention in recent years. Many algorithms have been proposed. Among them, sparse representation based face super-resolution approaches are able to achieve competitive performance. However, these sparse representation based approaches only perform well under the condition that the input is noiseless or has small noise. When the input is corrupted by large noise, the reconstruction weights of the input LR patches using sparse representation based approaches will be seriously unstable, thus leading to poor reconstruction results. To this end, in this paper, we propose a novel sparse representation based face super-resolution approach that incorporates a smooth prior to enforce similar training patches having similar sparse coding coefficients. Specifically, we introduce the fused Lasso to the least squares representation of the input LR image in order to obtain a stable sparse representation, especially when the noise level of the input LR image is high. Experiments are carried out on the benchmark FEI face dataset. Visual and quantitative comparisons show that the proposed face super-resolution method achieves comparable performance to the state-of-the-art methods under noiseless condition, and yields superior super-resolution results when the input LR face image is contaminated by strong noise.
Failure of montelukast to reduce sputum eosinophilia in high-dose corticosteroid-dependent asthma

Sputum eosinophilia is a sensitive predictor of benefit from corticosteroid treatment. Montelukast is a cysteinyl leukotriene antagonist, which also reduces sputum and blood eosinophils. The present study examined the possibility that montelukast has an added eosinophil-lowering effect in subjects with asthma who are corticosteroid responsive but relatively corticosteroid resistant. A total of 14 clinically stable adults with asthma requiring minimum treatment with a high-dose inhaled steroid or prednisone, with baseline sputum eosinophilia (≥5%), were randomised to receive 4 weeks of 10 mg montelukast or placebo daily in a double-blind crossover trial. The primary outcome was the effect of treatment on the percentage of sputum eosinophils. Secondary outcomes were changes in the blood eosinophil count, symptoms, forced expiratory volume in one second, peak expiratory flow and the need for salbutamol. The median (interquartile range, i.e. 75th–25th centile) for sputum eosinophils at baseline was 15.7% (22). The effect of adding montelukast was not significantly different from that of placebo, sputum eosinophils being 9.3% (18.9) after montelukast and 11.3% (22.8) after placebo. No difference was detected on secondary outcomes. No crossover interactions were observed. In conclusion, the addition of montelukast to existing high-dose corticosteroid therapy in subjects with asthma with elevated sputum eosinophils does not provide additional attenuation of airway eosinophilia.
