The Mathematical Model of the Study of Free Movement of Weapons on the Example of Kalashnikov Assault Rifles
Authors: Chirkov D V , Galagan L A , Sakhratov R Yu
Published: October 2018

Причиной рассеивания выстрелов при автоматической стрельбе является неоднообразие взаимодействия оружия, отклоняющегося от точки прицеливания под действием силовых факторов, и стрелка, по возможности компенсирующего эти отклонения. Представлена математическая модель исследования свободного (без участия стрелка) пространственного движения оружия, учитывающая газодинамические процессы в оружии, возникающие силовые факторы, удары при работе автоматики при их расположении вне центра масс стрелка. В расчетной схеме математической модели принято расположение центра вращения оружия, прижатого к плечу и неподвижного относительно него, на оси симметрии стрелка в центре его масс при удалении плечевого упора на объективных расстояниях по боку и высоте, характерных для среднестатистического стрелка. Расположение силовых факторов, типичных для работы автоматики, определяется компоновкой механизмов оружия. Обозначены силовые факторы, действующие в оружии и оказывающие влияние на его перемещения в пространстве, создавая опрокидывающие или стабилизирующие моменты относительно центра масс стрелка. Составлены уравнения вращательного движения оружия с учетом ударных взаимодействий в крайних положениях затворной рамы и при отпирании затвора кинематические уравнения, определяющие углы поворота оружия, а также отклонения точек попадания от точки прицеливания. Перечисленные элементы учтены в блок-схеме системы уравнений, определяющих движение автомата с отводом пороховых газов. Выходными данными являются значения опрокидывающих моментов и отклонения оружия от точки прицеливания, позволяющие расценивать устойчивость оружия при стрельбе как предысторию рассеивания при введении стрелка. Разработанная модель использования для оценки эффективности мероприятий для стабилизации автомата АК-47 в пространстве: уменьшение калибра с целью снижения импульса отдачи и использование дульных газовых устройств.
A Kind of Phase Enlargement of Semi-Markov Systems on the Example of Modeling a Synchronous Automated Line

Published: October 2018

В статье рассматривается фазовое укрупнение полумарковских систем, не требующее определения стационарного распределения вложенной цепи Маркова. Под фазовым укрупнением понимается эквивалентная замена полумарковской системы с общим фазовым пространством состояний системой с дискретным пространством состояний. Нахождение стационарного распределения вложенной цепи Маркова для систем с непрерывным фазовым пространством состояний является сложной и не всегда разрешимой задачей, так как в ряде случаев приводит к решению интегральных уравнений с ядрами, содержащими сумму и разность переменных. Для таких уравнений известно только частное решение, а общих решений на настоящий день не существует. Для этой цели доказывается лемма о виде функции распределения разности двух случайных величин при условии, что первая больше вычитаемой. Показано, что вид функции распределения разности СВ при указанном условии зависит от одной константы, которая определяется численным методом решения уравнения, приводимого в лемме. Использование данного метода демонстрируется на примере моделирования автоматизированной синхронной линии со свободным циклом функционирования. Автоматизированные синхронные линии со свободным циклом функционирования находят все большее применение в машино-приборостроении как имеющие значительное преимущество по сравнению с синхронными линиями, функционирующими по жесткому циклу, а также с автоматизированными линиями с рефлекторным управлением, обеспечивающими передачу продукции при наличии опроса датчиков окончания обслуживания, установленных на каждой позиции.

Prescriber Attitudes Toward Implementation of Pharmacogenomic Testing in a Family Medicine Residency Program
Authors: Gallipani Alyssa , Cope Rebecca , Fischetti Briann , Abraham Sherly , Ankireddypalli Arvind
Published: October 2018

Introduction: Few qualitative studies have explored the attitude of prescribers towards the implementation of pharmacogenomic testing in the family medicine (FM) setting, and none among FM residents. The purpose of this study was to describe the level of engagement and interest in the implementation of pharmacogenomic education and testing in an FM clinic within a residency program.
Methods: A qualitative study utilizing semistructured interviews was conducted among prescribers within the FM clinic at The Brooklyn Hospital Center (TBHC). Voluntary prescribers included FM residents and attendings. No prescribers were excluded. Prior to the interview, informational sheets about pharmacogenomics were provided to standardize participant knowledge base. The research team created an interview guide of specific open-ended questions. Interviews were audio recorded and transcribed until a point of saturation was achieved. Transcripts of interviews served as data for analysis. Coding and analysis were performed to develop a hypothesis. No formal statistical analysis was required.
Results: Of the total 28 providers eligible for participation, 15 were recruited and interviewed (53% response rate). Based on analysis of interview data, four key conceptual concerns emerged regarding benefits and risks of testing, feasibility, accessibility, and modification of FM residency training curricula.
Conclusion: Positive attitudes and perceptions provide support for pharmacogenomic education and testing to be incorporated into FM residency curricula. Addressing practical barriers, such as curricular education and training, will allow for expansion of such initiatives in the future.
An Analysis of Auditors' Going-Concern Reporting Accuracy in Private Firms
Authors: Hardies Kris , Vandenhaute Marie-Laure , Breesch Diane
Published: October 2018

SYNOPSIS

The accuracy of audit reports is often viewed as a signal for audit quality. Prior research shows that in the context of going-concern reporting in audit markets dominated by public firms, some auditors are more accurate than others (e.g., Big N firms). This study is the first large-scale study that investigates going-concern reporting accuracy in an audit market dominated by private firms. The threat of reputation and litigation costs incentivizes auditors to report accurately in markets dominated by public firms, but such incentives are largely absent in markets dominated by private firms. Hence, reporting accuracy in such markets might not vary across auditors. Our main analysis is based on a sample of 1,375 Belgian firms that ceased to exist within one year from the financial statement date. Our results show that the frequency of Type II misclassification does not vary across auditor types (Big 4 versus non-Big 4, audit firm and partner industry specialists versus non-specialists, more experienced versus less experienced, and female versus male auditors). Overall, these results cast doubt on the existence of quality differences among auditors in audit markets dominated by private firms.
Performance Feedback Type and Employees' Subsequent Willingness to Help Other Employees
Authors: Black Paul W. , Newman Andrew H. , Stikeleather Bryan R. , Waddoups Nathan J.
Published: October 2018

We investigate whether the type of performance feedback (individual versus relative) firms provide employees on one task alters employees' willingness to help other employees on a subsequent, unrelated task. Consistent with prior research, results from our experiment show that employees perform better on a production task when they receive relative performance feedback as opposed to individual performance feedback about the task. However, we document that the valence of RPI feedback appears to moderate the effect of RPI on subsequent helping behavior. Specifically, those who receive RPI feedback indicating that they performed (better) worse than another participant exhibit (lower) higher levels of helping behavior relative to those who receive only individual feedback. Our results highlight the complex tradeoffs confronting managers and management accountants when designing performance feedback systems and the need for them to consider employees' tasks holistically rather than in isolation when deciding what type of performance feedback to provide.

Difficult Cost Goals and Conflicting Honesty Incentives: The Influence of Decision Responsibility
Authors: Libby Theresa , Proell Chad A. , Smith Steven D.
Published: October 2018

We experimentally examine the effects of difficult goals and controllability on managerial honesty in a cost reporting setting. In our experiment, participants in the role of production managers make cost reporting decisions with economic incentives to over-report. We manipulate the presence of a difficult cost goal and whether managers perceive product costs as somewhat under their control. Our setting captures conflicting incentives of goal achievement and perquisite consumption, and we find that difficult cost goals do increase reporting honesty conditional on the presence of perceived ability to impact costs. Specifically, managers with decision responsibility report more honestly with a difficult cost goal than without, while managers without decision responsibility report with similar honesty with or without a cost goal. Our study provides evidence that decision right assignment moderates the honesty effects of difficult cost goals, with implications for firms' goal setting and organizational architecture choices.

Load Balancing and Thermal-Aware in Geo-Distributed Cloud Data Centers Based on Vlans
Authors: Khaleel Mustafa I.
Published: October 2018

Power consumption in datacenters has become an emerging concern for the cloud providers. This poses enormous challenges for the programmers to motivate new paradigms to enhance the efficiency of cloud resources through designing innovative energy-aware algorithms. However, balancing the weights over geographically dispersed datacenters has been shown to be essential in decreasing the temperature consumption per datacenter. In this paper, we have formulated a load balancing paradigm to exploit the idea of scheduling scientific workflows over distributed cloud resources to make system outcome more efficient. The proposed heuristic works based on three constraints. First, initiating cloud resource locality for tenants and calculating the shortest distance in order to direct module applications to the closet resources and conserving more bandwidth cost. Second, selecting the most temperature aware datacenters based on geographical climate to maintain electricity cost for the providers. Third, running multiple datacenters within the same geographical location instead of housing the entire workloads in a single datacenter. This allows providers to take a tremendous advantage of sustaining the system from degradation or even unpredictable failure which in turn will frustrate the tenants. Furthermore, applications are formulated as Directed Acyclic Graph (DAG)-structured workflow. For the underlying cloud hardware, our model groups the cloud servers to communicate as if they were in the same physical location. Additionally, both modes, on-demand and reservation, are supported in our algorithm. Finally, the simulation showed that our method was able to enhance the utilization rates about 67% compared to the baseline model.

It was also noted delay in the formation of skills in receptive speech and gross motor skills in accordance with the results of evaluation by using Vineland-II.
Improving the Numerical Accuracy of High Performance Computing Programs by Process Specialization
Authors: Benmouhoub Farah , Damouche Nasrine , Martel Matthieu
Published: October 2018

In high performance computing, nearly all the implementations and published experiments use floating-point arithmetic. However, since floating-point numbers are finite approximations of real numbers, it may result in hazards because of the accumulated errors. These round-off errors may cause damages whose gravity varies depending on the critical level of the application. To deal with this issue, we have developed a tool which im- proves the numerical accuracy of computations by automatically transforming programs in a source-to-source manner. Our transformation, relies on static analysis by abstract interpretation and operates on pieces of code with assignments, conditionals, loops, functions and arrays. In this article, we apply our techniques to optimize a parallel program representative of the high performance computing domain. Parallelism introduces new numerical accuracy problems due to the order of operations in this kind of systems. We are also interested in studying the compromise between execution time and numerical accuracy.

La grande crisi della ‘civiltà del denaro’
Authors: Basso Pietro
Published: October 2018

Luciano Gallino has been one of the very few scholars of social sciences to realize how deep the last general crisis was. In a series of remarkable books he describes the crisis as a big crisis, a double crisis, both financial and ecological, the crisis of ‘money’s civilization’. In the last period of this research work Gallino’s criticism of capitalist system has become truly radical. One of the specific issues he has increasingly focused on is the so-called job flexibility, which he sees more and more - in time of crisis - as a deceptive word to cover precariousness, the increasing precarity of life of millions of young, and not only young, workers.

Published: October 2018

Discourse concerning state control concept on natural resources in Article 33 clause (3) of the 1945 Constitution is very dynamic. Such dynamic can be seen on      a variety of conceptions of state control rights on natural resources formulated in various acts in natural resources area. Lack of single concept on ‘state control right’ will impact to unfavorable situation where natural resources shall escape from conception of state control right and into control not by the state. The Constitutional Court as the Guardian and Interpreter of the Constitution has a significant role to ascertain that an act in natural resources area really adopt the principle of state control on natural resources in Indonesia. This article analyzes on dynamics of conception of state control on natural resources in various acts and the role of the Constitutional Court in guarding and interpreting acts in natural resources in order to be in accordance with Article 33 clause (3) of the 1945 Constitution. From the result of analysis a conclusion is achieved that there are many different concepts    of state control on natural resources in various acts in natural resources area. The Constitutional Court indeed has made interpretation on state control right. In order to make the conception stronger it is necessary to have an act in natural resources area as instruction of Article 33 clause (5) of the 1945 Constitution that further provisions of Article 33 shall be regulated by an act. Moreover, DPR (The House of Representatives) and the Government have to make certain or definite the concept of state control right in every draft bill of natural resources area so that liberalism and capitalism stream will not erode the principle of state control right.
Sum decomposition of divergence into three divergences

Published: October 2018

Divergence functions play a key role as to measure the discrepancy between two points in the field of machine learning, statistics and signal processing. Well-known divergences are the Bregman divergences, the Jensen divergences and the f-divergences.In this paper, we show that the symmetric Bregman divergence can be decomposed into the sum of two types of Jensen divergences and the Bregman divergence.Furthermore, applying this result, we show another sum decomposition of divergence is possible which includes f-divergences explicitly.
Intentional binding as Bayesian cue combination: testing predictions with trait individual differences
Authors: Lush Peter , Roseboom Warrick , Cleeremans Axel , Scott Ryan Bradley , Seth Anil , Dienes Zoltan
Published: October 2018

Intentional binding refers to the subjective compression of the time between an action and its outcome, typically indicated by a forward shift in the judged time of an action toward its outcome (action binding) and the backward shift of an outcome toward the action that caused it (outcome binding). The effect is considered an implicit measure of the sense of agency as it is sensitive to intentional action without requiring explicit reflection upon agency. One way of explaining the sensitivity of intentional binding is to see it as a simple case of multisensory cue combination in which awareness of intentions increases knowledge of the timing of actions. Here we present results consistent with such a mechanism. An experience of involuntariness is central to hypnotic responding, and may arise from strategically being unaware of one’s intentions. Trait differences in the ability to respond to hypnotic suggestion may reflect differing levels of access to motor intentions, with highly hypnotisable people having relatively low access and low hypnotisable people greater access. In a contingent presentation of action and outcome events, low hypnotisables had more precise timing judgements of actions than highs, and showed weaker action binding than highs. These results support the theory that trait hypnotisability is related to access to information related to motor intentions, as increased availability of such information should support more precise judgements of the timing of an intentional action. Intentional binding may thus reflect the Bayesian combination of cross-modal cues.

Commons-Based Peer Production in the Work of Yochai Benkler
Authors: Papadimitropoulos Vangelis
Published: October 2018

Yochai Benkler defines commons-based peer production as a non-market sector of information, knowledge and cultural production, which is not treated as private property but as an ethic of open sharing and co-operation, and is largely enhanced by the Internet and free/open source software. This paper makes the case that there is a tension between Benkler’s liberal commitments and his anarchistic vision of the commons. Benkler limits the scope of commons-based peer production to the immaterial production of the digital commons, while paradoxically envisaging the control of the world economy by the commons. This paradox reflects a deeper lacuna in his work, revealing the absence of a concrete strategy as to how the immaterial production of the digital commons can connect to material production and control the world economy. The paper concludes with an enquiry into some of the latest efforts in the literature to fill this gap.
EXPERIMENTAL STUDIES ON THE QUASI-STATIC AXIAL CRUSHING BEHAVIOR OF FOAM-FILLED STEEL EXTRUSION TUBES
Authors: ISMAIL AL EMRAN
Published: October 2018

The concerns of automotive safety have been given special attention in order to reduce human fatalities or injuries. One of the techniques to reduce collision impact or compression energy is by filling polymeric foam into metallic tubes. In this work, polyurethane foam was introduced into the steel extrusion tubes and quasi-statically compressed at constant cross-head displacement. Different tube thicknesses and foam densities were used and these parameters were related to the crashworthiness aspect of the foam-filled structures. It is found that both tube thickness and foam density played an important role in increasing the crashworthiness behaviours of the structures but when the tube thickness reached certain value, foam density unable to properly work in increasing the energy absorption of the structures.

INTRODUCTION Alloy electrodeposition technologies can extend tremendously the potential of electrochemical deposition processes to provide coatings that require unique mechanical, chemical and physical properties [1]. There has been a great research interest in the development and characterization of iron-nickel (Fe-Ni) thin films due to their operational capacity, economic interest, magnetic and other properties [2]. Due to their unique low coefficient of thermal expansion (CTE) and soft magnetic properties, Fe-Ni alloys have been used in industrial applications for over 100 years [3]. Typical examples of applications that are based on the low CTE of Fe-Ni alloys include: thermostatic bimetals, glass sealing, integrated circuit packaging, cathode ray tube, shadow masks, membranes for liquid natural gas tankers; applications based on the soft magnetic properties include: read-write heads for magnetic storage, magnetic actuators, magnetic shielding, high performance transformer cores. comprise the simple baths whereas complex baths were prepared by adding ascorbic acid, saccharin and citric acid in simple baths. The effect of bath composition, pH and applied current density on coating appearance, composition, morphology and magnetic property were studied. Wet chemical analysis technique was used to analyze the coating composition whereas SEM and VSM were used to study the deposit morphology and magnetic property respectively. Addition of complexing agents in plating baths suppressed the anomalous nature of Fe-Ni alloy electrodeposition. Coatings obtained from simple baths were characterized by coarse grained non-smooth surface with/without microcracks onto it whereas those from complex baths were fine grained with smooth surfaces. Satisfactory saturation magnetization value of 131.13 emu/g in coating was obtained from simple bath. Coatings obtained from complex baths did not show normal magnetization behavior.

Experimental weak + vacuum protocol has been demonstrated using commercial QKD system based on a standard bi-directional ‘Plug & Play’ set-up. By making simple modifications to a commercial quantum key distribution system, decoy state QKD allows us to achieve much better performance than QKD system without decoy state in terms of key generation rate and distance. We demonstrate an unconditionally secure key rate of 6.2931 x 10-4per pulse for a 25 km fiber length.
TOWARDS A SCALABLE SCIENTIFIC DATA GRID MODEL AND SERVICES
Authors: Abdullah Azizol
Published: October 2018

Scientific Data Grid mostly deals with large computational problems. It provides geographically distributed resources for large-scale data-intensive applications that generate large scientific data sets. This required the scientist in modern scientific computing communities involved in managing massive amounts of a very large data collections that are geographically distributed. Research in the area of grid has given various ideas and solutions to address these requirements. However, nowadays the number of participants (scientists and institutions) that are involved in this kind of environment is increasing tremendously. This situation has lead to a problem of scalability. In order to overcome this problem we need a data grid model that can scale well with the increasing number of users. Peer-to-peer (P2P) is one of the architectures that is a promising scale and dynamism environment. In this paper, we present a P2P model for Scientific Data Grid that utilizes the P2P services to address the scalability problem. By using this model, we study and propose various decentralized discovery strategies that intend to address the problem of scalability. We also investigate the impact of data replication that addresses the data distribution and reliability problem for our Scientific Data Grid model on the propose discovery strategies. For the purpose of this study, we have developed and used our own data grid simulation written using PARSEC. We illustrate our P2P Scientific Data Grid model and our data grid simulation used in this study. We then analyze the performance of the discovery strategies with and without the existence of replication strategies relative to their success rates, bandwidth consumption and average number of hop.

Published: October 2018

In this paper, two clustering algorithms are proposed. In the first one, we investigate a clustering protocol for single hop wireless sensor networks that employs a competitive scheme for cluster head selection. The proposed algorithm is named EECS-M that is a modified version to the well known protocol EECS where some of the nodes become volunteers to be cluster heads with an equal probability.Â  In the competition phase in contrast to EECS using a fixed competition range for any volunteer node, we assign a variable competition range to it that is related to its distance to base station. The volunteer nodes compete in their competition ranges and every one with more residual energy would become cluster head. In the second one, we develop a clustering protocol for single hop wireless sensor networks. In the proposed algorithm some of the nodes become volunteers to be cluster heads. We develop a time based competitive clustering algorithm that the advertising time is based on the volunteer nodeâ€™s residual energy. We assign to every volunteer node a competition range that may be fixed or variable as a function of distance to BS. The volunteer nodes compete in their competition ranges and every one with more energy would become cluster head. In both proposed algorithms, our objective is to balance the energy consumption of the cluster heads all over the network. Simulation results show the more balanced energy consumption and longer lifetime.

This paper proposes a Multi-Level Sampling (MLS) approach for continuous Loss of Self-Similarity (LoSS) detection using iterative window. The method defines LoSS based on Second Order Self-Similarity (SOSS) statistical model. The Optimization Method (OM) is used to estimate self-similarity parameter since it is fast and more accurate in comparison with other estimation methods known in the literature. Probability of LoSS detection is introduced to measure continuous LoSS detection performance. The proposed method has been tested with real Internet traffic simulation dataset. The results demonstrate that normal traces have probability of LoSS detection below the threshold at all sampling levels. Meanwhile, false positive detection can occur where abnormal traces have probability of LoSS that imitates normal behavior at sampling levels below 100ms. However, the LoSS probability exceeds the threshold at sampling levels larger than 100ms. Our results show the possibility of detecting anomaly traffic behavior based on obtaining continuous LoSS detection monitoring

In this paper, simulation study was conducted to investigate the effect of spatial heterogeneity of multiple porosity fields on oil recovery, residual oil and microemulsion saturation. The generated porosity fields were applied into UTCHEM for simulating surfactant-polymer flooding in heterogeneous two-layered porous media. From the analysis, surfactant-polymer flooding was more sensitive than water flooding to the spatial distribution of multiple porosity fields. Residual oil saturation in upper and lower layers after water and polymer flooding was about the same with the reservoir heterogeneity. On the other hand, residual oil saturation in the two layers after surfactant-polymer flooding became more unequal as surfactant concentration increased. Surfactant-polymer flooding had higher oil recovery than water and polymer flooding within the range studied. The variation of oil recovery due to the reservoir heterogeneity was under 9.2%.
DESIGN AND IMPLEMENTATION OF POTENTIOMETER-BASED NONLINEAR TRANSDUCER EMULATOR
Authors: Khan Sheroz
Published: October 2018

This work attempts to design and implement in hardware a transducer with a nonlinear response using potentiometer. Potentiometer is regarded as a linear transducer, while a the response of a nonlinear transducer can be treated as a concatenation of linear segments made out of the response curve of an actual nonlinear transducer at the points of inflections being exhibited by the nonlinear curve. Each straight line segment is characterized by its slope and a constant, called the y-intercept, which is ultimately realized by a corresponding electronic circuit. The complete circuit diagram is made of three stages: (i) the input stage for range selection, (ii) a digital logic to make appropriate selection, (iii) a conditioning circuit for realizing a given straight-line segment identified by its relevant slope and reference voltage. The simulation of the circuit is carried using MULTISIM, and the designed circuit is afterward tested to verify that variations of the input voltage give us an output voltage very close to the response pattern envisaged in the analytical stage of the design. The utility of this work lies in its applications in emulating purpose built transducers that could be used to nicely emulate a transducer in a real world system that is to be controlled by a programmable digital system.
