PRICE-GENERATING CHARACTER OF INFORMATIONS ABOUT NET FINANCIAL RESULT IN THE CASE OF WARSAW STOCK EXCHANGE

For most governments in the world, a fundamentally strong economy is the goal of their politics. One of the determiners of such economy is operating and developed capital market. This process, however, entails the necessity of its effectiveness. In relation to the capital market, the effectiveness may be defined in three dimensions [Sharpe, 1992]. One of them is the so-called information efficiency. The first man who drew attention on the possibility of occurrence informatively effective capital market was L. Bachelier [1900]. In his study he included a theory of price formation on the French stock exchange. However, its first actual definition has been put forward much later by E. Fama [1965]. According to it, on efficient capital market “prices always fully reflect all available information”. There is a number of information that may impact on the prices of financial instruments. These include: news of profit sharing (dividend payments), stock exchange analysts' recommendations, transactions made by insiders, split or resplit shares and information not necessarily related to particular company or an economic sector. Moreover, this information may be evidences derived from accounting. Data from the accounting system has a very significant impact related to the prices of companies listed on global stock exchanges. They enable the investors’ risk on the capital market. Concerning to that, they can improve the selection of entities characterized by a good economic and financial situation. Placing funds in these can mean that investors will achieve above-average profits in the future.One of the most important data coming from the accounting system is the information about companies net financial result (net profit or loss). Informing market participants about the net financial result may affect the price volatility of the issuer's financial instruments. It was already written about in current of the capital market research in accounting in the 1960s [Ball, Brown, 1968]. Main aim of this paper was examination the impact of announcement information about net financial result on the market value the biggest companies listed on the Warsaw Stock Exchange grouped in the WIG20 index. To achieve this aim have used the event study methodology-one of the methods of measuring information efficiency of the capital market [Fama, 1969]. It is a research instrument used to assess investors’ reactions, while on the other hand it can be used as an element of financial market efficiency evaluation. For this purpose constructed 5-day long event window (where t0 was a day of announcement the financial report). Using the event study methodology, were calculated the abnormal returns for each quarterly report publications between 2016 and mid-2018 for each company in WIG20 index. Results of this paper are given below.

A new approach to elastography using a modified demons registration algorithm

Changes in tissue stiffness correlate with pathological phenomena that can aid the diagnosis of several diseases such as breast and prostate cancer. Ultrasound elastography measures the elastic properties of soft tissues using ultrasound signals. The standard way to estimate the displacement field from which researchers obtain the strain in elastography is the time-domain cross-correlation estimator (TDE). Optical flow (OF) methods have been also characterized and their use keeps increasing. We introduce in this paper the use of a Modified Demons Algorithm (MDA) to estimate the displacement field and we compare it with OF. A least-squares strain estimator (LSE) is applied to estimate the strain from the displacement. The input for the algorithm comes from the ultrasound scanner standard video output; therefore, its clinical implementation is immediate. To test the algorithm, a tissuemimicking phantom was modeled as a 10x10x5 cm region containing a centered 10mm cylindrical inclusion three times stiffer than the surrounding material, and its elastic behavior was simulated using COMSOL Multiphysics 3.2 software. Synthetic pre- and post-compression (1.25%) B-mode images were computer generated using FIELD II ultrasound simulator. Afterward, the algorithm was tested with a commercial CIRS breast elastography phantom, applying a 2% freehand compression. Axial displacement fields and strain figures are presented and in the case of the synthetic one compared to the ground truth given by the FE software. Although other researchers have used registration methods for elastography, as far as we know, they have not been used as stand alone but together with elastic modulus reconstruction or FE which iteratively varies material properties to improve registration.
Deculverting: reviewing the evidence on the ‘daylighting’ and restoration of culverted rivers

We review published references on ‘deculverting’ (also known as ‘daylighting’) projects in the United Kingdom and internationally. The aim of the review was to assess the objectives of implemented projects and to establish where evidence exists for the purported social, economic and environmental benefits of deculverting. The outcomes highlight the need for collaboration to collate detailed information on such projects, to support the further development of evidence‐based policy. It is clear that deculverting schemes can indeed exert considerable positive impacts, including ecological benefits, reduced flood risks, recreation for local communities and a stimulus for regeneration, but that the evidence for these impacts is sparse. We conclude that improvements in policy will help to maximise these opportunities, by encouraging the implementation of good practices.

Some restrictions are specific to specific groups of entrepreneurs only, while others are general. This article will discuss the constraints and opportunities for developing entrepreneurship in Serbia in current business conditions, with particular reference to entrepreneurship research in the city of Vranje in southern Serbia.
A micro and macro based examination of the effects of requirements changes on aerospace software maintenance

Requirements are the foundation of the software release process. They provide the basis for developing budgets, schedules, and design and testing specifications. Changing requirements during a software release process impacts the cost, schedule, and quality of the resulting product. We have collected data on 20 software releases in our environment to understand the source, magnitude, and effects of changing requirements on software maintenance releases. The benefits received include better management of releases and improved customer communications.
Modified Gram-Schmidt-based antenna selection for MIMO systems in correlated channels

A modified Gram-Schmidt (MGS)-based antenna selection scheme is proposed for multiple-input multiple-output (MIMO) systems in correlated channels. This MGS antenna selection strategy is developed based on an auxiliary parameter formulated by the projection component that is obtained from the GS orthogonalisation process. Consequently, the use of the MGS antenna selection algorithm is capable of achieving an improvement in system capacity and a substantial saving in system hardware of the multiple radio frequency chains associated with multiple antennas.

Communication Architecture of the IEC 61850-based Micro Grid System

As the power grids are integrated into one big umbrella called a "smart grid," communication protocol plays a key role in successful operations. The successful deployment of smart grid interoperability is a major hurdle that must be overcome. The micro grid, a small power system that distributes energy resource, is operated in diverse regions. Different vendors use different communication protocols in the operation of the micro grid. Recently, the IEC 61850 has been legislated to solve the interoperability problems in power utility automation. The present paper presents a micro grid system based on the IEC 61850 protocol. It consists of a micro grid monitoring system, a protocol converter that transforms serial data to IEC 61850 data, and distributed energy resource controllers for diverse DER nodes. A developed communication gateway can be deployed for DER controllers with serial links to exchange data with IEC 61850-based devices. The gateway can be extended to IEC 61850-based distribution automation systems, substation automation systems, or SCADA.

Different effects of sub-minimum inhibitory concentrations of gentamicin on the expression of genes involved in alginate production and biofilm formation of Pseudomonas aeruginosa

Background and Objectives: Antibiotics at sub-minimum inhibitory concentrations (sub-MIC) may alter bacterial virulence factors. The objective of this study was to investigate the effect of gentamicin at sub-MIC concentrations on the expression of genes involved in alginate production and biofilm formation of Pseudomonas aeruginosa. Materials and Methods: The broth microdilution method was used to determine the MIC of gentamicin for three P. aeruginosa clinical isolates (P1-P3) and standard strains (PAO1 and 8821M). Alginate production and biofilm formation of the bacteria in the presence and absence of sub-MIC concentrations of gentamicin were measured using microtiter plate and carbazole assay, respectively. The real-time PCR method was used to determine the effect of gentamicin at sub-MIC concentrations on the expression level of genes involved in biofilm formation (pelA and pslA) and alginate production (algD and algU). Results: Gentamicin at sub-MIC concentrations significantly reduced alginate production, biofilm formation, and the expression of alginate and biofilm-encoding genes in clinical isolate P1. This inhibitory effect was also observed on the alginate production of 8821M strain and biofilm formation of PAO1strain. In clinical isolates, P2 and P3, alginate production, biofilm formation, and the expression of alginate and biofilm-encoding genes were significantly increased in exposure to sub-MIC concentrations of gentamicin. Conclusion: This study showed that different phenotypic changes in clinical isolates and standard strains of P. aeruginosa in exposure to sub-MIC concentrations of gentamicin are associated with changes in the expression of virulence genes. Further researches are required to understand the mechanisms involved in regulating the expression of virulence genes after exposure to sub-MIC concentrations of antibiotics.
Introducing engineering education in the middle school

This paper first describes a new three-year, longitudinal project that is implementing engineering education in three middle schools in Australia (grade levels 7-9). This important domain is untapped in Australia. Hence, as a starting point, we conducted a context analysis to help situate engineering education in a school system. We report on this analysis with respect to findings from one of two literature-based surveys that gathered middle-school student responses in mathematics (n=172) and science (n=166) towards understanding their dispositions for engineering education. ANOVA indicated gender differences for 3 out of 23 items in both mathematics and science. In addition, the majority of students agreed or strongly agreed with 17 of the 23 survey items, however, there were some differences between mathematics and science. We conclude the paper with some recommendations for establishing engineering education in schools, including the development of partnerships among engineering and education faculties, school systems, and industry to develop contemporary engineering resources to support school-level mathematics, science, and technology.
Flexible Sketches and Inflexible Data Bases: Visual Communication, Conscription Devices, and Boundary Objects in Design Engineering

Engineering sketches and drawings are the building blocks of technological design and production. These visual representations act as the means for organizing the design to production process, hence serving as a "social glue" both between individuals and between groups. The author discusses two main capacities such visual representations serve in facilitating distributed cognition in team design work As conscription devices, they enlist and organize group participation. As boundary objects, they facilitate the reading of alternative meanings by various groups involved in the design process. The introduction of computer-aided design into this visual culture of engineering restructures relationships between workers in ways that can hamper the flexibility necessary for these crucial capacities to take place. The data are drawn from a study of the daily practices of engineers engaged in redesigning a turbine engine package. The method is participant observation.

A review study on sustainable development of ultra high-performance concrete

A systematic literature review was undertaken in this report to illustrate the development concepts and properties of ultra-high performance concrete (UHPC). UHPC's affluent development relies on its compositional content, water–binder (w/b) ratio, and design mix approach, which contributes to denser and comparatively more homogeneous packaging of particles. Numerous research studies from around the world were used to compile a database on UHPC mechanical and durability properties. Moreover, the results of this study reveal that the curing conditions, aggregates, fibre dosage and characteristics, and curing time are the most important elements in determining the mechanical and durability qualities of UHPC. Furthermore, due to its ultra-high-strength features, superior fatigue behavior, and extremely low porosity, UHPC is considered a practical and long-term alternative for improved sustainable building, resulting in increased resilience to hostile environments. Besides that, attempts are being taken to resolve existing challenges (such as high initial costs, a lack of skills, and a lack of design code) and their solutions to their widespread economic use. This study aims to help architects, builders, and other construction stakeholders better grasp UHPC's basic features and capacities, which will help to understand this durable and long-lasting building material.
LYAPUNOV-BASED CONTROL OF LIMIT CYCLE OSCILLATIONS IN UNCERTAIN AIRCRAFT SYSTEMS

of Dissertation Presented to the Graduate School of the University of Florida in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy LYAPUNOV-BASED CONTROL OF LIMIT CYCLE OSCILLATIONS IN UNCERTAIN AIRCRAFT SYSTEMS By Brendan Bialy May 2014 Chair: Warren E. Dixon Major: Aerospace Engineering Store-induced limit cycle oscillations (LCO) affect several fighter aircraft and is expected to remain an issue for next generation fighters. LCO arises from the interaction of aerodynamic and structural forces, however the primary contributor to the phenomenon is still unclear. The practical concerns regarding this phenomenon include whether or not ordnance can be safely released and the ability of the aircrew to perform mission-related tasks while in an LCO condition. The focus of this dissertation is the development of control strategies to suppress LCO in aircraft systems. The first contribution of this work (Chapter 2) is the development of a controller consisting of a continuous Robust Integral of the Sign of the Error (RISE) feedback term with a neural network (NN) feedforward term to suppress LCO behavior in an uncertain airfoil system. The second contribution of this work (Chapter 3) is the extension of the development in Chapter 2 to include actuator saturation. Suppression of LCO behavior is achieved through the implementation of an auxiliary error system that features hyperbolic functions and a saturated RISE feedback control structure. Due to the lack of clarity regarding the driving mechanism behind LCO, common practice in literature and in Chapters 2 and 3 is to replicate the symptoms of LCO by including nonlinearities in the wing structure, typically a nonlinear torsional stiffness. To improve the accuracy of the system model a partial differential equation (PDE) model of a flexible wing is derived (see Appendix F) using Hamilton’s principle. Chapters 4
Risk Concession Model for Build/Operate/Transfer Contract Projects

This paper extends the build-operate-transfer (BOT) concession model (BOTCcM) to establishing a risk concession model for BOT contract projects. The decision for a concession period is one of the most important decisions in determining a BOT contract. BOTCcM presents an alternative method to assist in determining a concession period that can protect the basic interests of both the investor and the government concerned. However, there is a major limitation in using the model, namely it gives no consideration to the impacts of risks on the estimation of various economic variables in the model. This study considers the risk impacts to the BOTCcM model and presents an additional risk concession model. This model provides an approach for formulating a concession period to consider the impacts of risks and, at the same time, protect the basic interests of both the investor and the government concerned. A hypothetical case is used to show the procedures of formulating the risk concession period through the assistance of the Monte Carlo simulation method.
On the quality of fault injection for off-the-shelf components in safety-critical systems

Fault Injection (FI) is a family of techniques that emulates hardware and/or software faults by deliberately inserting them into a system component in order to analyze system behavior under faulty conditions, i.e. whether the system can tolerate faults. It is well recognized that Fault Injection is a powerful means for dependability assessment, especially when the system is composed by third-party components. Due to its importance for supporting dependability evaluation of OTS-based systems in safety-critical domains, it is important to assure the quality of fault injection techniques, i.e accuracy and representativeness properties. This dissertation focused on three fault in- jection techniques employed in systems that integrates OTS components, i.e. Software Fault Injection based on binary code mutation, Interface Error Injection (IEI) and SoftWare-Implemented Fault Injection (SWIFI). Three diﬀerent problems were addressed: (i) the accuracy of SFI based on code mutations; (ii) the representativeness of existing error models on which IEI techniques are based on; (iii) the representativeness and the eﬀectiveness of existing SWIFI techniques when applied to systems deployed on multicore processors.
Modified FOLFIRINOX versus sequential chemotherapy (FOLFIRI/FOLFOX) as a second‐line treatment regimen for unresectable pancreatic cancer: A real‐world analysis

Although second‐line treatment for pancreatic cancer has been proven to have survival benefit, it is not clear which is the most preferred regimen. This study compared the efficacy and safety of modified FOLFIRINOX (mFOLFIRINOX) and sequential chemotherapy (FOLFIRI/FOLFOX) as a second‐line treatment regimen for unresectable pancreatic cancer.
Elastisches Matching multimodaler dreidimensionaler medizinischer Datensätze am Beispiel des Visible Female Datensatzes

Rechnergestützte anatomische Modelle des menschlichen Körpers gewinnen bei der medizinischen Ausbildung und Therapieplanung zunehmend an Bedeutung. Zur Erstellung solcher Modelle werden häufig durch bildgebende Verfahren der Medizin gewonnene Schnittbildaumahmen herangezogen. Die im Rahmen des Visible Human Projects [1] erstellten Farbphotographien und CT-Schnittbilder sind aufgrund der hohen Auflösung und des hohen Kontraste besonders gut für die Modellerstellung geeignet. Um diese Farbphotographien und CT-Schnittbilder gemeinsam für die Erstellung eines Modells verwenden zu können, müssen diese mittels geeigneter Matching-Verfahren aufeinander abgebildet werden.
