One-shot 3D Surface Reconstruction from Instantaneous Frequencies - Solutions to Ambiguity Problems

Phase-measuring profilometry is a well known technique for 3D surface reconstruction based on a sinusoidal pattern that is projected on a scene. If the surface is partly occluded by, for instance, other objects, then the depth shows abrupt transitions at the edges of these occlusions. This causes ambiguities in the phase and, consequently, also in the reconstruction. This paper introduces a reconstruction method that is based on the instantaneous frequency instead of phase. Using these instantaneous frequencies we present a method to recover from ambiguities caused by occlusion. The recovery works under the condition that some surface patches can be found that are planar. This ability is demonstrated in a simple example.
No-Arbitrage Condition of Option Implied Volatility and Bandwidth Selection

Abstract A standard approach to option pricing is based on Black-Scholes type (BS hereafter) models utilizing the no-arbitrage argument of complete markets. However, there are several crucial assumptions, such as that the option underlying log-returns follow normal distribution, there is unique and deterministic riskless rate as well as the volatility of underlying log-returns. Since the assumptions are generally not fulfilled, the BS-type models mostly provide false results. A common market practice is therefore to invert option pricing model and using market prices of highly liquid options to get a so called implied volatility (IV). The BS model at one time moment can be related to the whole set of IVs as given by maturity/moneyness relation of tradable options. One can therefore get IV curve or surface (a so called smirk or smile). Since the moneyness and maturity of IV often do not match the data of valuated options, some sort of estimating and local smoothing is necessary. However, it can lead to arbitrage opportunity, if no-arbitrage conditions on state price density (SPD) are ignored. In this paper, using option data on DAX index, we analyze the behavior of IV and SPD with respect to different choices of bandwidth parameter h and a set of bandwidths, which violates no-arbitrage conditions, are identified. Moreover, it is documented that the change of h implies interesting changes in the violation interval of moneyness. We also show the impact of h on the total area of SPD under zero, which can be seen as a degree of no-arbitrage violation.
Policing in a Rough Neighbourhood: The Reform of the RUC

Introduction In November 1999, the Royal Ulster Constabulary (RUe) was awarded the George Cross in recognition of their gallantry and sacrifice in the struggle against terrorism in Northern Ireland. This was only the second occasion that the award had been made to a collective unit of people. The previous occasion on which such a tribute had been given was by King George VI to the people of Malta who withstrood such a ferocious onslaught from the Axis forces in the Second World War. Malta played a vital role in supporting the allied war effort in the Mediterranean theatre and incurred a high cost for doing so. The RUC were in the front line of the fight against terrorism in Northern Ireland. They faced both Republican and Loyalist terrorist organisations, major public order problems on an annual basis as well as the normal range of policing problems such as burglaries, road traffic issues and the drug trade. The RUC paid a high price in terms of casualties during the course of the Northern Ireland conflict. Over 300 of its officers were killed both on and off duty. The number of RUC officers who were injured in the course of the troubles is over 8,000. These are very high casualty figures for a police force in a liberal democratic state to sustain. They are far higher than anything that a mainland British constabulary of comparable size would face or that the Garda Siochana would confront in the Irish Republic. This article is divided into four sections. The first section looks at the problem of policing ethnically divided societies and why they pose such seemingly intractable difficulties. The second section gives an overview of the record of the RUC from the beginning of the Northern Ireland state. The third section reviews the main critiques of the RUC from the perspectives of Republicans, Loyalists and civil libertarians. The fourth section examines the peace settlement based on the Good Friday agreement and its implications for the future of policing Northern Ireland. It looks at the proposals of the Patten report for the reform of the RUC and the difficulties that they have encountered.

Computer Aided Transient Stability Analysis

A program for handling and improving the transient stability of the Iraqi Super Grid electrical network was developed. The idea was demonstrated by applying it to the outages of the main generating units. The methodology was built upon a state of increasing power transfer through the healthy portion of network during disturbances. There were three parts concerned; the first part was the developing of the load flow program using fast decoupled method and the transient stability program using Modified Euler’s method in the step by step solution, the second part was the engagement between the two programs, the third part was the application of the new program on the Iraqi supper grid network (400 kV).
Occurrence of an incomplete C8 molecule in homozygous C8 deficiency in man

Sera from unrelated individuals with recurrent Neisserial infections lacked C8 hemolytic activity, but contained a protein that is antigenically related to C8. Immunochemical analysis revealed complete identity of the C8-related protein of all three sera and a marked antigenic deficiency compared with normal C8. The C8-related protein was isolated from serum by adsorption to immobilized anti-C8 IgG, elution with 3 M guanidine, and subsequent gel filtration. Upon sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis, the abnormal protein resembled the alpha-gamma subunit of normal C8 with respect to mobility and its ability to be cleaved upon reduction into the alpha and gamma chains. The beta chain present in normal C8 was absent. Sedimentation equilibrium analysis indicated a molecular weight of 86,000 for the abnormal C8 protein, which is identical to that of the alpha-gamma subunit of normal C8. Amino acid analysis revealed no significant difference between the abnormal C8 and normal alpha-gamma. Unlike normal C8, the abnormal protein did not bind to EAC1-7 or to SC5b-7; however, upon addition to the deficient serum of beta chain isolated from normal C8, hemolytic activity was restored and formation of SC5b-9 occurred. We concluded that the dysfunctional C8 protein in the three individuals' serum is identical to the alpha-gamma subunit of normal C8 and that this form of C8 deficiency is distinct from the C8 deficiencies previously reported in which the entire three-chain protein is lacking.
Sympathetic Tone Induced by High Acoustic Tempo Requires Fast Respiration

Many studies have revealed the influences of music, and particularly its tempo, on the autonomic nervous system (ANS) and respiration patterns. Since there is the interaction between the ANS and the respiratory system, namely sympatho-respiratory coupling, it is possible that the effect of musical tempo on the ANS is modulated by the respiratory system. Therefore, we investigated the effects of the relationship between musical tempo and respiratory rate on the ANS. Fifty-two healthy people aged 18–35 years participated in this study. Their respiratory rates were controlled by using a silent electronic metronome and they listened to simple drum sounds with a constant tempo. We varied the respiratory rate—acoustic tempo combination. The respiratory rate was controlled at 15 or 20 cycles per minute (CPM) and the acoustic tempo was 60 or 80 beats per minute (BPM) or the environment was silent. Electrocardiograms and an elastic chest band were used to measure the heart rate and respiratory rate, respectively. The mean heart rate and heart rate variability (HRV) were regarded as indices of ANS activity. We observed a significant increase in the mean heart rate and the low (0.04–0.15 Hz) to high (0.15–0.40 Hz) frequency ratio of HRV, only when the respiratory rate was controlled at 20 CPM and the acoustic tempo was 80 BPM. We suggest that the effect of acoustic tempo on the sympathetic tone is modulated by the respiratory system.
The Validity of Young Schema Questionnaire 3 rd Version and the Schema Mode Inventory 2 nd Version on the Greek Population

The present study is about the validation of the Young Schema Questionnaire 3rd version and the Schema Mode Inventory 2nd version on the Greek population. The participants were both male (58.7%) and female (41.2%). The participants were also without psychopathology, outpatients and inpatients, varied in ages from 19 to 62 years, with the majority being in the age group between 31 - 35. From the analysis conducted, both questionnaires’ factors had high internal consistency in all three participant’s groups. We have also conducted a Pearson analysis between the Early Maladaptive Schemas and Schema Modes, which produced some strong positive and negative correlations. Finally in the present study, we are presenting a Cohen analysis conducted between the three different groups of participants (non-patients, outpatients and inpatients).
Multi-Robot Auctions for Allocation of Tasks with Temporal Constraints

We propose an auction algorithm to allocate tasks that have temporal constraints to cooperative robots. Temporal constraints are expressed as time windows, within which a task must be executed. There are no restrictions on the time windows, which are allowed to overlap. Robots model their temporal constraints using a simple temporal network, enabling them to maintain consistent schedules. When bidding on a task, a robot takes into account its own current commitments and an optimization objective, which is to minimize the time of completion of the last task alone or in combination with minimizing the distance traveled. The algorithm works both when all the tasks are known upfront and when tasks arrive dynamically. We show the performance of the algorithm in simulation with different numbers of tasks and robots, and compare it with a baseline greedy algorithm and a state-of-the-art auction algorithm. Our algorithm is computationally frugal and consistently allocates more tasks than the competing algorithms.
Anatomical Variation of Human Collector Channel Orifices

Purpose To examine the anatomical variation of normal human collector channel orifices and their relationship with Schlemm's canal. Methods Ten human anterior segments fixed by immersion or perfusion were dissected radially and further divided by fine dissection into corresponding inner and outer wall segments. The tissues were dehydrated, critical-point dried, sputter coated, and examined by scanning electron microscopy. Images were obtained at magnifications from ×200 to ×10,000. Selected radial collector channel regions were processed for plastic embedding. Results Two classes of collector channel orifices were identified. Simple oval orifices (54.7 ± 4.6–μm diameter) were lined with endothelial cells and most often occurred on a planar region of Schlemm's canal outer wall. Complex orifices (62.7 ± 3.4–μm diameter) were often found associated with septal columns and bridges, and typically covered with flap-like structures (10–40 μm) that extended between the inner and outer wall and over the collector channel orifices. Both simple and complex orifices had complete or partial lip-like rims. In orifices with partial rims, a trough-like groove was often visible on the outer wall surface opposite the lip. Transected septa and inner and outer wall adhesion sites were often found in association with complex collector channel orifices. Conclusions Collector channel orifice structure varied from simple ovals to complex tethered flaps and bridges. Collector channel orifices with complex flaps connect the inner and outer walls of Schlemm's canal, and may serve to enhance and regulate aqueous outflow in these regions.
Book review: Karen Tracy and Jessica S Robles, Everyday Talk: Building and Reflecting Identities

presence of one another while at the same time both helping to build and attending to relevant context and action. Developing an understanding of participation roles would seem to be necessary in helping the reader understand the interactional roles discussed earlier in this chapter. Part V, Chapters 20–22, aims to explore how witnesses and attorneys use a range of techniques to prove accusations or to avoid implications for blame in legal settings. Part VI, Chapters 23 and 24, draws upon the speech exchange system of television news interviews and explores how the work of interviewing is conducted. What makes this part appropriately understandable for the reader is the use of case studies that illustrate the principles described in the chapters. Part VII, Chapters 25 and 26, illustrates how the work of business and other organizations is done through talk. It would have been more engaging and perhaps more tangible for the reader if the author had included some more examples, drawn from the domain of service encounters. Service encounters are a pervasive and fundamental activity in everyday life whereby products, information or commodities are exchanged between a service provider and a customer. A ‘Conclusions’ chapter provides the reader with two excerpts and encourages them to compare them with the more simplified transcriptions in Chapter 1. Here, the author highlights the need for detailed transcripts as this enriches one’s understanding of the intricacies of talk-in-interaction. The book would have benefitted from more careful editing to remove typographical errors, some of which have consequences for readers. For example, on page 241, the author refers to Chapter ‘20’, which in fact should be ‘21’. In conclusion, this is an important textbook that engages closely with theoretical and practical aspects of CA. The book is very ‘user-friendly’ and approaches its subject matter from a straightforward and common sense point of view. No doubt, this book will be of interest to students of sociology, linguistics and communication studies.
Metacognition and Science Teaching

ABSTRACT In this review study,the concept of metacognition whose emergence goes back to early 1970s in education was investigated and primarily, basic definitions related to the concept of metacognition have been discussed and identified. Afterwards, the studies carried out together on a conceptual change and metacognition have been investigated and some recommendations for developing metacognition in classrooms have been proposed.
An efficient hash-based algorithm for minimal k-anonymity

A number of organizations publish microdata for purposes such as public health and demographic research. Although attributes of microdata that clearly identify individuals, such as name and medical care card number, are generally removed, these databases can sometimes be joined with other public databases on attributes such as Zip code, Gender and Age to re-identify individuals who were supposed to remain anonymous. "Linking" attacks are made easier by the availability of other complementary databases over the Internet. k-anonymity is a technique that prevents "linking" attacks by generalizing and/or suppressing portions of the released microdata so that no individual can be uniquely distinguished from a group of size k. In this paper, we investigate a practical model of k-anonymity, called full-domain generalization. We examine the issue of computing minimal k-anonymous table based on the definition of minimality described by Samarati. We introduce the hash-based technique previously used in mining associate rules and present an efficient hash-based algorithm to find the minimal k-anonymous table, which improves the previous binary search algorithm first proposed by Samarati.
Performance evaluation of an all-optical OCS/OPS-Based network for intra-data center connectivity services

As the size of Data Centers (DCs) and the amount of information managed by them grows, nowadays electronic-based intra-Data Center Networks (DCNs) start to become a limiting factor, not providing enough scalability nor flexibility to support highly dynamic traffic profiles. The LIGHTNESS intra-DCN solution, based on a hybrid all-optical OCS/OPS architecture, aims to overcome such limitations, providing an architecture suitable for the management of both long- and short-lived traffic flows. In this paper, we evaluate the performance of such a hybrid architecture in terms of blocking probability for various traffic conditions, highlighting its benefits against pure OCS or OPS networks.
Steering angle determination using CART and voting

In autonomous navigation using camera, it is important to robustly find drivable region. After finding drivable region, we compute the steering angle for the vehicle. In this paper, we propose a robust algorithm for finding the drivable region. First, we find drivable region using classification and regression tree (CART). Finally, we find the epipole of the road using voting. We show the feasibility and robustness of proposed algorithm in experiment using real images.
Optimization of water allocation based on the economic loss analysis under different drought scenarios

Drought has become a great constraint in the process of sustainable development of human society and China is one of the countries frequently affected by severe droughts. Thus, along with research on the drought prediction and prevention, it is of key importance to study how to reasonably allocate the limited water resources during drought. When drought occurs, there is a struggle for water among various users. The main objective of this study is to define an appropriate proportion of water to be distributed between industry and agriculture in order to avoid heavy economic losses when suffering the emergency drought. So, we designed a simple algorithm to account for economic losses and on that basis to choose the optimum scheme of water allocation under different drought scenarios.
SHEPHERD: A Shipping-Based Query Processor to Enhance SPARQL Endpoint Performance

Recent studies reveal that publicly available SPARQL endpoints exhibit significant limitations in supporting real-world applications. In order for this querying infrastructure to reach its full potential, more flexible client-server architectures capable of deciding appropriate shipping plans are needed. Shipping plans indicate how the execution of query operators is distributed between the client and the server. We propose SHEPHERD, a SPARQL client-server query processor tailored to reduce SPARQL endpoint workload and generate shipping plans where costly operators are placed at the client site. We evaluated SHEPHERD on a variety of public SPARQL endpoints and SPARQL queries. Experimental results suggest that SHEPHERD can enhance endpoint performance while shifting workload from the endpoint to the client.
CMOS Passive Phase Shifter With Group-Delay Deviation of 6.3 ps at $K$-Band

This paper presents a CMOS vector-sum-based phase shifter with a flat group-delay deviation of 6.3 ps at K-band. The theoretical analyses confirm the effects of the nonideal phase-invertible variable attenuator (PIVA) on the increasing of the root-mean-square (rms) phase error and magnitude variation of the phase shifter. The design procedures, which can eliminate the effects from the voltage-dependent parasitics of the reflection load and the nonideal directional coupler, are reported to make an ideal phase reversal and reduce the attenuation-dependent phase shifting of the PIVA. The prototype of the phase shifter, which consists of one 3-dB directional coupler, two PIVAs, and one power combiner, are realized by using synthetic transmission lines for the circuit miniaturization. The circuit is fabricated in standard 0.18-μm 1P6M CMOS technology with a size of 560 μm × 560 μm excluding the testing pads. The comparisons between simulated and experimental results show that the prototype can cover full 360° phase shifting with less than 1.5° of rms phase error and 0.45 dB of magnitude variation from 22.0 to 26.0 GHz. The input P1dB and IIP3 of the prototype with a relative phase shifting of 292.5° are 12.0 and 28.0 dBm, respectively.
Adaptive state estimation for a class of uncertain nonlinear systems with output time-delays

In this paper, we propose an adaptive observer for nonlinear systems with slope restricted nonlinearities, unknown parameters and delayed outputs. The delay is assumed constant and the unknown parameter is assumed piece-wise constant. Based on the Lyapunov-krasovskii approach, we show that, for sufficiently small values of the time-delay, both state estimation and parametric convergence are ensured under a condition of persistent excitation. The result is illustrated via two numerical examples.
Symphony of Eigenvalues : A Prototype for Sonification in System Dynamics

Sonification is the use of nonspeech audio to convey information and can enhance the ability of system dynamics in the analysis of relationships between structure and behavior. Today’s desktop computing power allows users of software such as MAX and MSP to create a variety of sounds whose parameters are determined by the mappings of imported data. The prototype discussed used pitch, timbre and amplitude to describe the values and first and second order differences, respectively, of the state variables. A two-parameter model of Hares and Lynx demonstrated the sonic effects, while another two-parameter model of Alcohol and Cells featured the addition of sonified eigenvalues, illustrating the combined fields’ potential to provide an early warning detection to changes in feedback loop dominance. The prototype’s ability to express 10 parameters of interest with just 4 sounds should appeal to the fields of business, education and the arts.
Naturalistically observed swearing, emotional support, and depressive symptoms in women coping with illness.

OBJECTIVE The goal of this study was to explore the intra- and interpersonal consequences of swearing. Specifically, it investigated what implications swearing has for coping with and adjustment to illness. METHODS The present project combined data from two pilot studies of 13 women with rheumatoid arthritis and 21 women with breast cancer. Participants wore the Electronically Activated Recorder, an unobtrusive observation sampling method that periodically records snippets of ambient sounds, on weekends to track spontaneous swearing in their daily interactions, and completed self-reported measures of depressive symptoms and emotional support. RESULTS Naturalistically observed swearing in the presence of others, but not alone, was related to decreases in reported emotional support and increases in depressive symptoms over the study period. Further, decreases in emotional support mediated the effect of swearing on disease-severity adjusted changes in depressive symptoms. CONCLUSION These exploratory results are consistent with the notion that swearing can sometimes repel emotional support at the expense of psychological adjustment. This is one of the first studies to examine the role of swearing, a ubiquitous but understudied psychological phenomenon, in a medical context.
