Correctness Witness Validation using Predicate Analysis

Witness validation is an important step for increasing the confidence in the results of software verification. This is especially true when the verifier claims that the specification holds, i.e., when it outputs a correctness witness. While there are currently two validators for correctness witnesses, it is generally desirable to add new, conceptually different algorithms for validation. The goal of this thesis is to explore how predicate abstraction can be used in that regard. Possible approaches include reusing the invariants in the witness for the initial predicate precision or adding them as additional verification goals to the original verification task.
Effect of Multitasking on Simulator Sickness and Performance in 3D Aerodrome Control Training

Background. Air traffic controllers need to use their cognitive resources to cope with multiple tasks while monitoring air traffic. They are trained through advanced 3D simulators; however, they might demonstrate simulator sickness symptoms during this training. The relationship between multitasking and simulator sickness and the influence of different tasks on these variables can be investigated to inform further training practices for an efficient traffic monitoring. Purpose. The purpose of this quasi-experimental research was to explore the influence of different working positions and multitasking scenarios on simulator sickness and performance in 3D Aerodrome Control Training. Method. Thirteen undergraduate students from a civil aviation school participated in a time-series experimental design. Nausea, disorientation and oculomotor disturbances were measured before and after conducting different multitasking scenarios in an aerodrome control simulator. A 20-item simulation performance scale was also used. Performance differences and the relationship between simulator sickness and performance were addressed through parametric tests. Results. Findings revealed that tower-ground positions created higher levels of nausea. Performance scores varied in different scenarios. Simulator sickness was higher in females. Total sickness correlated negatively with performance in all scenarios. Conclusion. Certain tasks have different influences on both simulator sickness and performance. Concurrent multitasking seems to trigger simulator sickness further. The degree of simulator adaptation, test anxiety and physiological measures of the process should be considered in further research.

the International Database on Longevity

Since the first symposium, “Living to 100 and Beyond: Survival at Advanced Ages” held in 2002, a collaborative effort has been made to assemble an international database on longevity, gathering validated longevity records for people having reached at least their 110 birthday. More than 15 countries, including the United States of America, Canada and Japan, along with European countries, have been participating in this Supercentenarian project. Collaboration with national statistical offices or health departments has allowed the investigators to obtain complete lists of alleged supercentenarians in most countries. Different validation processes are then undertaken by the participating teams. By March 2004, more than 500 validated records had been gathered. This paper first evaluates the quality of data according to several criteria, such as the country of residence or the validation process undertaken, and then provides an estimation of the mortality trajectory up to age 114.
ADGN : An Algorithm for Record Linkage Using

This paper presents an algorithm for record linkage that uses multiple indicators derived from combinations of fields commonly found in databases. Specifically, the quadruplet of Address (A), Date of Birth (D), Gender (G), and Name (N) and any triplet of A-D-G-N (i.e., ADG, ADN, AGN, and DGN) also link records with an extremely high likelihood. Matching on multiple identifiers avoids problems of missing data, inconsistent fields, and typographical errors. We show, using a very large database from the State of Texas, that exact matches using combinations A, D, G, and N produce a rate of matches comparable to 9-Digit Social Security Number. The rate of false negatives appears to be less than 1 percent. Further examination of the linkage rates show that reporting of the data at a higher level of aggregation, such as Birth Year instead of Date of Birth and omission of names, makes correct matches between databases highly unlikely, protecting an individual’s records. ∗Stephen Ansolabehere is the Frank G.

A Cahn-Hilliard type equation with degenerate mobility and single-well potential. Part I: convergence analysis of a continuous Galerkin finite element discretization

We consider a Cahn-Hilliard type equation with degenerate mobility and single-well potential of Lennard-Jones type. This equation models the evolution and growth of biological cells such as solid tumors. The degeneracy set of the mobility and the singularity set of the cellular potential do not coincide, and the absence of cells is an unstable equilibrium configuration of the potential. This feature introduces a nontrivial difference with respect to the Cahn-Hilliard equation analyzed in the literature. We formulate a continuous finite element approximation of the problem, where the positivity of the solution is enforced through a discrete variational inequality. We prove the existence and uniqueness of the discrete solution together with the convergence to the weak solution. We present simulation results in one and two space dimensions. We also study the dynamics of the spinodal decomposition and the growth and scaling laws of phase ordering dynamics. In this case we find similar results to the ones obtained in standard phase ordering dynamics and we highlight the fact that the asymptotic behavior of the solution is dominated by the mechanism of growth by bulk diffusion.
Efficiency and Equity of Land Policy in Developing Country Cities : Evidence from the Mumbai Mills Redevelopment ⇤

Land policy in developing country cities places significant restrictions on formal sector developers but often fails to reign in informal development. To what extent does this pattern reduce city efficiency, and how are the effects shared between the rich and poor? We address these questions in three steps. First, we exploit a unique natural experiment in Mumbai that led 15% of central city land occupied by the city’s defunct textile mills to come onto the market for redevelopment in the 2000s. Second, we use a “deep learning” approach to measure slums from satellite images, and combine this with administrative sources to construct a uniquely spatially disaggregated dataset spanning the period. Third, we develop a quantitative general equilibrium model of a city featuring formal and informal housing supply to guide our empirical analysis. We document a large increase in the supply of formal construction on mill sites, and find substantial spillovers on nearby locations that led slums to redevelop into formal housing. Our findings suggest that land policy can reduce the efficiency of developing country cities by misallocating land away from its optimal use, but policies that promote formal housing supply may have unintended consequences for equity by reducing the stock of relatively affordable housing in slums. ⇤Preliminary.

Performance Measurement in Regional Self-Government

Regional self-government in the Republic of Croatia is regulated by Law on local and regional selfgovernment. There are 20 counties and the City of Zagreb as regional self-government units. Public organisations have been implemented some paradigms for managing internal business processes, risk management, financial management and control, in last 10 years, as it was earlier implemented in private sector. In this article authors will analyse regional selfgovernment in the Republic of Croatia. The main goal of this article is to investigate opinions of examinees about performance measurement indicators for regional self-government using four standard perspectives of Balanced Scorecard Method (BSC). The survey, on which is based this article, in two regional self-government institutions (counties) has to determine which of BSC perspectives are the most important from the employees point of view and to determine which performance indicators are suitable for efficiency and effectiveness in regional selfgovernment.
Effects of Spatial Distribution of Heat and Grip Areas for Tablet Computer Use

The dissipation of heat from a tablet computer can be a limiting factor for hardware design, and this is affected by power consumption, the central processing unit (CPU) and the thickness of the casing. If the tablet casing gets too hot it affects user’s thermal comfort and may even cause skin burns. Consequently, this study investigated the effect of different spatial layouts of heat distribution on user thermal comfort. The areas that are less frequently contacted by fingers were identified on the back surface of a simulated tablet computer.
Universality of the Calibration Curves-the Universality Law

The experimental and theoretical study of the unique magnetic properties of ferromagnetic steels with residual stresses has attracted considerable attention in recent articles. One fundamental aspect of the welding procedure is how the lattice mismatch between the different welding zones induces characteristic changes in the structural and magnetic properties of the ferromagnetic steel. According to our most recent work, the direct manifestation of the intimate relation between the strain state and magnetism stems from magnetostriction through magneto-elastic coupling. We have established the existence of a universal mechanism linking magnetic to mechanical features. The universal (among different steels) character of the effect suggests a novel route towards the non-destructive evaluation of mechanical stresses in welded zones.
1 Perceived Space in the HTC Vive

Underperception of egocentric distance in virtual reality has been a persistent concern for almost 20 years. Modern headmounted displays (HMDs) appear to have begun to ameliorate underperception. The current study examined several aspects of perceived space in the HTC Vive. Blind-walking distance judgments, verbal distance judgments, and size judgments were measured in two distinct virtual environments (VEs)—a highquality replica of a real classroom and an empty grass field—as well as the real classroom upon which the classroom VE was modeled. A brief walking interaction was also examined as an intervention for improving anticipated underperception in the VEs. Results from the Vive were compared to existing data using two older HMDs (nVisor SX111 and ST50). Blind-walking judgments were more accurate in the Vive compared to the older displays, and did not differ substantially from the real world nor across VEs. Size judgments were more accurate in the classroom VE than the grass VE and in the Vive compared to the older displays. Verbal judgments were significantly smaller in the classroom VE compared to the real classroom and did not significantly differ across VEs. Blind-walking and size judgments were more accurate after walking interaction, but verbal judgments were unaffected. The results indicate that underperception of distance in the HTC Vive is less than in older displays but has not yet been completely resolved. With more accurate space perception afforded by modern HMDs, alternative methods for improving judgments of perceived space—such as walking interaction—may no longer be necessary.
Land use and land cover change detection through spatial approach: A case study of Mangaluru Taluk, Karnataka

Land cover is a physical appearance of land and represents its ecological status. Land use/land cover changes are due to human intervention, natural disturbance and succession. The present study aimed at monitoring the land cover changes in Mangalore region during the period 1997 to 2017. Remote sensing and Geographical Information System (GIS) techniques were used to determine the land use and land cover changes based on the analysis of temporal Landsat-5 and Landsat-8 satellite imagery. Ground truth observations were performed to check the accuracy of the classification. The present study brought to light that the forest area that occupied 37% of the Taluk’s area in 1997 has reduced to 31% in 2017. Other classes like agricultural land, built up area, water bodies and barren land have also experienced changes. Built-up lands (settlements) have increased from 6 per cent to 23 per cent of the total area. The high land vegetation and forest cover areas are disappearing rapidly; water bodies like lakes are also diminishing. Mangalore city is one of the fastest developing cities in India. Proper land use planning is essential for a sustainable development of Mangalore Taluk.
Aalborg Universitet Analysis and Control of Modular Multilevel Converter with Split Energy Storage for Railway Traction Power

In this paper, a railway power conditioner (RPC) based on modular multilevel converter (MMC) with split supercapacitor energy storage system (SCESS) is studied. In this case, the MMC-SCESS based RPC could not only provide normal negative sequence currents (NSC) compensation but also could reduce the impact of power fluctuations caused by the locomotive braking or startup on the electric grid. Firstly, this paper analyzes the power flow patterns and deduces the reference circulating current under different operation modes of MMC-SCESS based RPC. Then, the control objectives of MMC-SCESS based RPC are divided into two categories including the balance control and the current tracking control. The balance control methods are developed for the submodules (SMs) capacitor voltages and the state of charge (SoC) of the supercapacitor, which are associated with the operation modes. To ensure the current tracking performance, a model predictive direct current control (MPDCC) method is presented for MMC and bidirectional energy converter (BEC). Finally, the effectiveness of the proposed control methods is verified by the experimental results of a downscaled prototype.
ZenHackAdemy : Ethical Hacking

Cybersecurity attacks are on the rise, and the current response is not effective enough. The need for a competent workforce, able to face attackers, is increasing. At the moment, the gap between academia and real-world skills is huge and academia cannot provide students with skills that match those of an attacker. To pass on these skills, teachers have to train students in scenarios as close as possible to real-world ones. Capture the Flag (CTF) competitions are a great tool to achieve this goal, since they encourage students to think as an attacker does, thus creating more awareness on the modalities and consequences of an attack. We describe our experience in running an educational activity on ethical hacking, which we proposed to computer science and computer engineering students. We organized seminars, outside formal classes, and provided online support on the hands-on part of the training. We delivered different types of exercises and held a final CTF competition. These activities resulted in growing a community of students and researchers interested in cybersecurity, and some of them have formed ZenHack, an official CTF team.
Knowledge Communication Problems between Experts and Decision Makers: an Overview and Classification

In this article we examine the difficulties of knowledge communication among experts and decision makers. We begin by outlining where and how the communication of expertise from specialists to managers is crucial. We then review theoretical constructs that highlight knowledge transfer problems among experts and decision makers. On the basis of this review and using the results from six focus groups and thirty interviews with engineers and managers, we categorise these transfer challenges into five major groups. We distinguish among expert? and manager? caused problems, reciprocal problems, problems due to the interaction situation and problems caused by the organisational context. These categories can be used to guide research on the micro? aspects of knowledge transfer. Managers can use these problem categories to identify and reduce knowledge transfer barriers in their interaction with specialists.

This paper discussed a low profile rectangular patch microstrip antenna design working on dual-band 1.8 GHz and 2.4 GHz. Dual-band characteristic is achieved by using inset-feed point and slot size adjustment. The designed antenna was printed on a FR4 substrate with relative permittivity of 4.4 and a thickness of 1.6 mm with patch size 40 x 29 mm. The measurement results show that the realized antenna successfully working on dual-band, achieving bandwidth of 45 MHz and 95 MHz, gain of 4.08 dBi and 5.79 dBi for 1.8 GHz and 2.4 GHz subsequently.
PARGenes : Molecular Probes to Pathological Assessment in Breast Cancer Progression

Taking the issue of tumor categorization a step forward and establish molecular imprints to accompany histopathological assessment is a challenging task. This is important since often patients with similar clinical and pathological tumors may respond differently to a given treatment. Protease-activated receptor-1 (PAR1), a G protein-coupled receptor (GPCR), is the first member of the mammalian PAR family consisting of four genes. PAR1 and PAR2 play a central role in breast cancer. The release of N-terminal peptides during activation and the exposure of a cryptic internal ligand in PARs, endow these receptors with the opportunity to serve as a “mirror-image” index reflecting the level of cell surface PAR1&2-in body fluids. It is possible to use the levels of PARreleased peptide in patients and accordingly determine the choice of treatment. We have both identified PAR1 C-tail as a scaffold site for the immobilization of signaling partners, and the critical minimal binding site. This binding region may be used for future therapeutic modalities in breast cancer, since abrogation of the binding inhibits PAR1 induced breast cancer. Altogether, both PAR1 and PAR2 may serve as molecular probes for breast cancer diagnosis and valuable targets for therapy.
Gene pro fi ling and characterization of arginine kinase-1 ( MrAK-1 ) from freshwater giant prawn ( Macrobrachium rosenbergii )

Arginine kinase-1 (MrAK-1) was sequenced from the freshwater prawn Macrobrachium rosenbergii using Illumina Solexa Genome Analyzer Technique. MrAK-1 consisted of 1068 bp nucleotide encoded 355 polypeptide with an estimated molecular mass of 40 kDa. MrAK-1 sequence contains a potential ATP:guanido phosphotransferases active domain site. The deduced amino acid sequence of MrAK-1 was compared with other 7 homologous arginine kinase (AK) and showed the highest identity (96%)withAK-1 from cherry shrimp Neocaridina denticulate. The qRT-PCR analysis revealed a broad expression of MrAK-1 with the highest expression in the muscle and the lowest in the eyestalk. The expression of MrAK-1 after challenge with the infectious hypodermal and hematopoietic necrosis virus (IHHNV) was tested in muscle. In addition, MrAK-1 was expressed in Escherichia coli by prokaryotic expression plasmid pMAL-c2x. The optimum temperature (30 C) and pH (8.5) was determined for the enzyme activity assay. MrAK-1 showed significant (P < 0.05) activity towards 10e50mMATP concentration. The enzyme activity was inhibited by a-ketoglutarate, glucose and ATP at the concentration of 10, 50 and 100 mM respectively. Conclusively, the findings of this study indicated that MrAK-1 might play an important role in the coupling of energy production and utilization and the immune response in shrimps. 2011 Elsevier Ltd.
