Controlling sequence length of DS-IR-UWB to enhance performance of multi-WBAN systems
Authors: Dinh Nguyen Cong , Hiep Pham Thanh , Yua Obinata , Van Son Vu 
Published: December 2018

Abstract
The international standard of wireless body area networks (WBANs), ie IEEE 802.15.6, was established in Feb. 2012, and this standard decided spreading code as a suppressing interference technology. However, the sequence length of spreading code is fixed, hence it is difficult to guarantee secure communications due to noise and interference from other WBANs. In this paper, we propose utilizing direct sequence impulse radio ultra wideband (DS-IR-UWB) for multi-WBAN systems, and then analyze multi-WBAN systems theoretically, derive equations of inter-WBAN interference, packet error rate (PER) and throughput. Furthermore, to guarantee secure communications, the desired PER is introduced, and then an algorithm is proposed to take the control of sequence length of DS-IR-UWB in order to ensure that the PER of system is always below the desired PER while maximizing the throughput. The numerical evaluation shows that the sequence length of proposed control method is changed according to the SNR and the number of WBANs, it lets the proposed algorithm of control of sequence length outperform the conventional fixed sequence length method.
Motional EMF/MMF in moving medium with magnetic monopoles
Authors: Zor Ömer 
Published: December 2018

Abstract
We derived the motional emf/mmf (electromotive force/magnetomotive force) in moving medium (in a Galilean frame) with magnetic monopoles using two different formulations: one where the Lorentz fields are continuously differentiable vector functions and one where they are not required to be. We then compared the two formulations in physical meaning.
Population Size Estimation and Linkage Errors: the Multiple Lists Case
Authors: Di Consiglio Loredana , Tuoto Tiziana 
Published: December 2018

Abstract
Data integration is now common practice in official statistics and involves an increasing number of sources. When using multiple sources, an objective is to assess the unknown size of the population. To this aim, capture-recapture methods are applied. Standard capture-recapture methods are based on a number of strong assumptions, including the absence of errors in the integration procedures. However, in particular when the integrated sources were not originally collected for statistical purposes, this assumption is unlikely and linkage errors (false links and missing links) may occur. In this article, the problem of adjusting population estimates in the presence of linkage errors in multiple lists is tackled; under homogeneous linkage error probabilities assumption, a solution is proposed in a realistic and practical scenario of multiple lists linkage procedure.
Statistical Matching as a Supplement to Record Linkage: A Valuable Method to Tackle Nonconsent Bias?
Authors: Gessendorfer Jonathan , Beste Jonas , Drechsler Jörg , Sakshaug Joseph W. 
Published: December 2018

AbstractRecord linkage has become an important tool for increasing research opportunities in the social sciences. Surveys that perform record linkage to administrative records are often required to obtain informed consent from respondents prior to linkage. A major concern is that nonconsent could introduce biases in analyses based on the linked data. One straightforward strategy to overcome the missing data problem created by nonconsent is to match nonconsenters with statistically similar units in the target administrative database. To assess the effectiveness of statistical matching in this context, we use data from two German panel surveys that have been linked to an administrative database of the German Federal Employment Agency. We evaluate the statistical matching procedure under various artificial nonconsent scenarios and show that the method can be effective in reducing nonconsent biases in marginal distributions, but that biases in multivariate estimates can sometimes be worsened. We discuss the implications of these findings for survey practice and elaborate on some of the practical challenges of implementing the statistical matching procedure in the context of linkage nonconsent. The developed simulation design can act as a roadmap for other statistical agencies considering the proposed approach for their data.

Published: December 2018

AbstractThe situation when groundwater considerably rises above the “normal” level, water intake, lowering of groundwater levels and other relevant practical tasks require the drainage facilities. The most effective techniques of numerical studies of the corresponding boundary problems at present time are methods of dealing with inverse boundary value problems (conformal and quasi-conformal mappings). As basis of this research we used the case of combining the fictitious domain methods with quasi-conformal mappings of the solution of nonlinear boundary value problems for the calculation of filtration regimes in environments with free boundary areas (depression curves) and zones of “mountainous” areas.This paper reviews the stationary issue of flat-vertical stationary non-pressure liquid filtration to horizontal symmetric drainage. In the paper a practical methodology for solving boundary value problems on conformal mappings is suggested for the calculation of the filtration process in the horizontal symmetrical drainage.The idea of block iterative methods was used during the creation of the corresponding algorithm which is based on the alternating “freeze” of the anticipated conformance parameter, the internal and boundary connections of the curvilinear area.The results of the conducted numerical calculations confirmed the effectiveness of the suggested problem formulations and algorithms of their numerical solution and the possibility of their use in the modelling of nonlinear filtration processes occurring in horizontal drainage systems, as well as in the design of drainage facilities and optimizing other hydrosystems. Therefore these results are of great importance.
Evaluation of hydro-agricultural techniques and assessment of know-how implemented by traditional societies: Case of the region of Béni-Snous in the city of Tlemcen – Algeria
Authors: Fecih Abla , Habi Mohammed , Morsli Boutkhil 
Published: December 2018

AbstractIn the past, rural society has always been able to implement some forms of community management of space, water and land that have served as a support for the survival of populations that are often too large for the available resources. The mountainous region of Béni-Snous offers a wide variety of strategies for water and soil fertility conservation management; it presents a form of adaptation of man to the strong physical constraints and thus constitutes a hydro-agricultural and cultural heritage which unfortunately has not yet aroused all the interest it deserves and of which one can be inspired. The ingenuity of these traditional systems, which have survived throughout history, challenges us to analyse and study these systems more seriously, particularly from the technical and organizational side. Our study was conducted in this context. The present work aims to evaluate the traditional systems of water and soil fertility conservation management, which are encountered on the mountains of Béni-Snous, which is characterized by a semi-arid climate. These systems represent a kind of creativity that is, at the same time, practical, organizational and social. The assessment of the state of water and soil management and conservation structures showed that 78% of them are currently functional and valorised. Given their importance, all mobilization and water management structures are still functional; they showed a good cost-effectiveness ratio.
Optimization of irrigation cropping pattern by using linear programming: Case study on irrigation area of Parsanga, Madura Island, Indonesia
Authors: Juwono Pitojo T. , Limantara Lily Montarcih , Rosiadi Fathor 
Published: December 2018

AbstractThe irrigation area of Parsanga is located in Sumenep Regency, Madura Island of Indonesia. This irrigation area is 500 ha and the existing cropping pattern is paddy–paddy–second crop. There is water discharge deficiency due to the existing cropping pattern mainly in the dry season. Thus, this study intends to optimize the cropping pattern for 3 condition so that it can produce the maximum benefit of agricultural product. The first cropping pattern is paddy/second crop–second crop–paddy/second crop; the second proposition is paddy/second crop –paddy/second crop–second crop; and the third proposition is paddy–second crop–paddy/second crop. The optimization analysis is carried out by using the linear programming. The suggested three cropping patterns are not only able to solve the water deficiency; they can also present the more production benefit than the existing condition.
Sustainable management of water resources in terms of the water needs for agricultural purposes in small rural communes based on the example of the Grybów commune, Poland
Authors: Kopacz Marek , Kowalczyk Agnieszka , Smoroń Sylwester , Ostrach Zbigniew 
Published: December 2018

AbstractThe article presents the results of the analysis of water needs in agricultural production of the Grybów commune (the district of Nowy Sącz, the Małopolska province). The aim of this study was to determine both the current water needs for agricultural purposes as well as changes in this regard based on structural and production data. The guidelines specified in the Ordinance of the Minister of Infrastructure of 14 January 2002 concerning average norms of water consumption were applied to determine water needs. The average annual water demand of crops together with permanent grassland (meadows, pastures) amounts to 23.7 mln m3, of which about 2.15 mln m3 is for winter wheat, 1.92 mln m3 for potatoes and 17.6 mln m3 for permanent grassland. Significant amounts of water (over 130,000 m3) are used also for watering home gardens and cultivating vegetables in plastic tunnels and greenhouses. Water needs for animals farming reach about 235,000 m3 in a year. Most water is needed for farming the cattle. It is predicted that the demand for water in the agricultural sector of the commune will increase by about 5.5% by 2030. Therefore, the activities monitoring the awareness of water saving and proper water management among the population of the villages are important.
Socio-economic factors affecting agro-forestry technology adoption in Nyando, Kenya

Published: December 2018

AbstractAgro-forestry (AFR) technologies are perceived to improve livelihoods and natural resource sustainability of the rural households. Despite their aggressive promotion by multiple national and international agencies, the adoption of AFR technologies has been minimal in Kenya. This study conducted a survey to examine the socio-economic factors that affect the adoption process in Nyando, Kenya. Results revealed that farmers with bigger farms and higher education were more likely to adopt the new technology. Additionally, farmers were quicker to adopt technology if they had an increase in crop yields and had stayed longer in the study area. Generally, wealthier famers tended to adopt more AFR technology than those with less income. Access to information was the only factor strongly correlated with the rest of the independent variables. The results suggest that, adoption would be more enhanced with a clear focus on extension activities, income enhancing AFR practices and soil amelioration technologies. This study may be replicated in other parts of Kenya and East Africa to improve the level of AFR technology adoption for sustainable rural development.
Estimated soil water storage within a historical bunker during the growth period of vegetation
Authors: Pardela Łukasz , Kowalczyk Tomasz 
Published: December 2018

AbstractThe objective of the study was to estimate the variation of soil water retention on the site of a historical bunker, an element of the former Wrocław Fortress in Poland. Measurements of soil moisture in the study area were taken in the period from March to September, 2017. Measurements of volumetric soil moisture were taken by means of a hand-held gauge, type FOM/mts with an FP/mts probe, operating on the basis of the reflectometric technique TDR. Soil moisture measurements realized in the vegetation period demonstrated that soil moisture resources in profiles situated in the section of the bunker varied within the range of 37–135 mm in the layer of 50 cm, and 66–203 mm in the layer of 100 cm. The maximum differences of the average value of soil moisture of the soil profiles studied in the period covered by the measurements were 31 mm and 56 mm, respectively. This indicates a significant differentiation of the retention properties of soils used for the construction of individual shelter areas.
Performance analysis of a reservoir in arid region Case study: Babar reservoir, Aurès region, Algeria
Authors: Tebbi Fatima Z. , Dridi Hadda , Kalla Mahdi 
Published: December 2018

AbstractLong term and mid-term reservoir operation involves derivation of rule curves for optimal management of the available resource. The present work deals with reservoir operation in the Aurès arid region. As an example, Babar reservoir is selected to apply the proposed approach which estimates all the water balance terms, especially those which are random as water inflows. For each demand scenario a reservoir operation optimization model using Explicit Stochastic Dynamic Programming (ESDP) is performed, to derive optimal rule curves based on historical operating records (Jan 2002–Dec 2013) and using “Reservoir” R package®. Subsequently, risk analysis is conducted for these different demand scenarios rules by the RRV (reliability, resilience, vulnerability) metrics. Results show the advantage of using the “Reservoir” R package for a rapid and an easy analysis of the performance criteria jointly with the optimization algorithm to Re-operate Reservoir operation.

AbstractThe results of the study devoted to assessment of accuracy and reliability of the CROPWAT 8.0 software application calculations of the evapotranspiration and crop water requirements are represented in the article.The study was based on the results of the perennial field experiments, conducted during the period from 2012 to 2017 at the irrigated lands of the South of Ukraine with different crops, namely: sweet corn, grain corn, soybean, sorghum. We assessed accuracy of the CROPWAT 8.0 software application by the comparison of the calculated values with the real ones. We determined considerable differences between the calculated crops evapotranspiration values and crops irrigation requirements and the real ones obtained in the field experiments. The difference was the most essential in case of the drip-irrigated sweet corn crop and averaged to 46.05% for evapotranspiration and 89.20% for irrigation water requirements, correspondingly. Overhead sprinkler irrigated crops are likely to be more suitable for accurate evapotranspiration prediction by using the CROPWAT 8.0. The slightest discrepancy between the calculated and actual values of the studied parameters were determined on the overhead sprinkler irrigated grain corn crops, where the differences averaged just to 15.86% for evapotranspiration and 41.63% for irrigation norm. The results of the study gave us an opportunity to conclude that CROPWAT 8.0 software application should not be used without previous calibration and adjustment of the crop coefficients for the concrete agricultural production conditions.

Published: December 2018

Abstract
Distribution of dairy products is one of the most important activities in the production process deciding about the organization of production and the course of technological processes. Such products should be provided with suitable containers with protective coatings, maintain the appropriate temperature during transport, and most importantly, the sterility of the means of transport. Choosing the right packaging for perishable products is not an easy matter, as it has to fulfil many functions. The article presents some aspects of the packaging system and legal conditions for the distribution of selected dairy products. In the first chapter, short introduction for the issue of packaging market of dairy products is presented. Second chapter outlines the selected legal acts regarding food transport in Poland. Selected aspects in terms of choosing the type of packaging and used materials are described in chapter 3. The last chapter contains conclusions and final remarks for the distribution of selected dairy products.
Other Stories: Experimental Forms of Contemporary Historying at the Crossroads Between Facts and Fictions
Authors: Sugiera Małgorzata 
Published: December 2018

Summary
The process of questioning the authority of academic history—in the form in which it emerged at the turn of the 19th century—began in the 1970s, when Hayden White pointed out the rhetorical dimension of historical discourse. His British colleague Alun Munslow went a step further and argued that the ontological statuses of the past and history are so different that historical discourse cannot by any means be treated as representation of the past. As we have no access to that which happened, both historians and artists can only present the past in accordance with their views and opinions, the available rhetorical conventions, and means of expression.
The article revisits two examples of experimental history which Munslow mentioned in his The Future of History (2010): Robert A. Rosenstone’s Mirror in the Shrine (1988) and Hans Ulrich Gumbrecht’s In 1926 (1997). It allows reassessing their literary strategies in the context of a new wave of works written by historians and novelists who go beyond the fictional/factual dichotomy. The article focuses on Polish counterfactual writers of the last two decades, such as Wojciech Orliński, Jacek Dukaj, and Aleksander Głowacki. Their novels corroborate the main argument of the article about a turn which has been taking place in recent experimental historying: the loss of previous interest in formal innovations influenced by modernist avant-garde fiction. Instead, it concentrates on demonstrating the contingency of history to strategically extend the unknowability of the future or the past(s) and, as a result, change historying into speculative thinking.
In Defence of Lost Causes: Counter(F)Actual Recasting of Biographies in Polish Contemporary Theatre
Authors: Wojtyra Wiktoria 
Published: December 2018

Summary
This article considers the impact of counterfactual strategies on the most recent Polish theatrical practices dealing with biographies of “historical” figures. The re-occurrence of these past agents on the stage will be viewed in light of the biographical turn in the humanities as well as from the perspective of Jacques Derrida’s concept of hauntology. Seemingly, both trends share a need to create an alternative space for the expression of a contemporary self which is marked by disunity and disintegration. Subjects of current semi-biographical projects are those whose voices have once been neglected, marginalised, or oppressed because of their gender, social background, or political views. This account examines the ways in which counterfactual strategies enable us to grasp the polyphonic condition of a modern subject and to see, in traces left by different Other(s), touchstones for social and political change. By taking the play Tu Wersalu nie będzie! (No Versailles over here!) by Rabih Mroué as the core case study of the analysis, I aim to demonstrate how counterfactual strategies animate emancipatory potential ascribed to the arrival of the phantom of controversial Polish politician Andrzej Lepper. His death in unknown circumstances becomes a point of divergence in which Lepper’s existence layers into counterfactual scenarios. Counterfactual strategies enable many approaches to view Lepper’s figure without the ethically dubious act of speaking in his name. By unsettling claims of truth, counterfactual strategies unravel how “facts” about Lepper resurfaced in mass media, thereby constructing his stereotyped and over-generalised image. The play has a form of investigation which, by employment of counterfactualism, reenacts the oppression of a mainstream media discourse against the disturbing Other epitomised by Lepper.

Transparency in general election and/or the election of governor, regent, and mayor, was one of the principal election. The party which was demanded to always do this principle was the organizer. Transparency in the production and implementation of the rules and transparency was about the budgeting etc. In the certain context, transparency was required in a system. Transparency in the mayor and vice election of Kupang in 2017 was the research that wanted to analyze how the subsystem in the candidate system processed. The system of the theory explained that system can be separated to each component to be analyzed as the independent entity and the component can be added as linear to picture the whole system. There were three general approaches to evaluate the subsystem. The holistic approach was to check the subsystem in a system. The functional approach to saw the top of the system to check the role in the bigger system. This study wanted to reveal the phenomenon of the political candidates in a system, how the elements of the subsystem were linear connected and influenced one to another, or not. Participant in mayor election was a couple of the candidates form a political party or the individual candidates that was recommended by a number of people. The public involvement that hardly seen, had to be from the local citizen that will be comped form political parties or individual candidates. This process was to determine the candidates of the mayor election of Kupang in 2017. The candidates should have the good and clean public institution management. This study reveals that each subsystem (input, process, and output) still had problems dan needed mending either the rules or procedures of the implication on every element that involved in the whole system. Individual candidates, from the beginning, had to be open about their intention so that the public did not refuse them. Verification procedures had to be simplified, the amount and the spreading of the supporter also had to be evaluated. This improvement had to be made by the rules which were the law. The process and procedure to determine the parties cadre in the public position had to be opened to the public and to the parties cadre. Key : transparency, candicate system processed, the mayor and vice election,
