Published: May 2017

Wireless Fidelity (Wi-Fi) is the modern telecommunication technology nowadays being so widely used and developed at operating frequency of 2.4 GHz, that needs microstrip antenna as best suited supporting means for transmitting and receiving data signals as well at its wave transceiver subsystem. The proposed antenna design were consists of four elements rectangular patch antenna with peripheral slits technique arranged in a linear array of 2x2 operating at the frequency of 2.4 GHz until 2.5 GHz. In addition to that, the feeding technique used in this research is microstrip fed line. The simulation from this research resulted in reducing the size of related antenna dimension up to 17% compared to that of four elements array without peripheral slits. It is also apparent that the bandwidth of the proposed antenna is 320 MHz (2.253 GHz–2.573 GHz) which is equivalent to bandwidth increase percentage of 13.07%, The simulation results in the center of frequency 2.448 GHz obtained return loss of -26.14 dB with a VSWR of 1.104. The measurement results obtained bandwidth of the proposed antenna is 150 MHz (2.424 GHz–2.574 GHz) which is equivalent to 12% increase of bandwidth percentage. The results of measurements process at the center of frequency 2.448 GHz obtained value of return loss of -16.88 dB with VSWR of 1.304.

Małżeństwo kryminału z historią, czyli uwag kilka o kryminałach retro Konrada T. Lewandowskiego
Authors: Tierling-Śledź Ewa 
Published: May 2017

Autorka artykułu wyraża przekonanie, iż na przełomie XX i XXI wieku spotykamy się ze swoistą restytucją historii w różnych odmianach i nurtach literatury, czego dowodem może być między innymi twórczość Konrada T. Lewandowskiego. Celem artykułu jest ukazanie sposobów „użytkowania historii” w kryminałach retro tego autora. Po przedstawieniu wyznaczników gatunku, badaczka śledzi obecne w powieściach Lewandowskiego różne odmiany historycznego prawdopodobieństwa, przechodzenie autora od prawdy historycznej do „historii niebyłej”. Stawia też pytanie o konsekwencje takiego operowania historią dla odbiorcy prozy historycznej u progu XXI wieku.

Published: May 2017

AbstractThe proposed intelligent method, which is based on the pressure data and the spatial location of the adjacent drilled wells, and the spatial continuity of the targeted region, is able to establish the formation pressure profile with credibility, the safe window with credibility of drilling fluid density, the probability profile of drilling risk and the risk interval of drilling operation. As a result, the proposed method achieves the intelligent identification of drilling risk in complex formations.In this intelligent method, the concept of formation pressure matrix is introduced firstly, and an epitaxial stratigraphic pressure migration algorithm is established to calculate the pressure of the targeted wells in the same tectonic region based on the depth adjustment and the inverse distance weighting algorithm. Secondly, the probability of drilling risk is calculated. Thirdly, the membership function of different degree interval is constructed by fuzzy mathematics theory combining with the accident record of drilled wells; and finally, divide the membership degree of drilling operation risk to achieve the intelligent identification of drilling risk. The intelligent method has been successfully applied in BD gas field in Indonesia. Nine drilling accidents such as kicks, collapses, leakages and stickings have been accurately identified in a certain well.The formation pressure of adjacent drilled wells is transplanted to the targeted wells and the pressure prediction is more accurate. Meanwhile, combined with the accident records of drilled wells, the intelligent identification of drilling risk can be carried out. The two issues mentioned above have been the focus of researchers. Under normal circumstances, the designers use stratigraphic comparison method, in which the formation pressure of the drilled wells is directly applied to the targeted well and does not consider the spatial distribution characteristics of the targeted formation. And the designers cannot intuitively determine the possibility of drilling risk according to the numerical drilling risk probability value. This intelligent method gives the transplantation method calculating the formation pressure of the targeted well in the same tectonic region and divides the drilling risk interval. This method has been used to analyze the risks in BD gas field in Indonesia and the LW oil field in South China Sea. Case studies were carried out to verify the method, in which the predicted formation pressure was compared with that derived from the LWD. The results showed that the maximum relative errors were within 2.76%. Example analysis showed that the identifying result of this method agreed with the actual engineering.The identification results of proposed intelligent method agrees with the engineering practical situation, satisfies the need of drilling engineering and can provide basis for identifying risk in drilling design.
Novel Well Modelling Approach Enhances Daily Production Rate Estimation and Allocation Process in an Intelligent Oil Field, Abu Dhabi
Authors: Rubio Erismar , Caicedo Sergio , BinAmro Ahmed , Davila Rayner 
Published: May 2017

Abstract
Hydrocarbon allocation becomes essential when facilities are shared for various contributing wells or reservoirs. Uncertainty in the reassignment factor can significantly impact operators’ daily decisions, reservoir health, and ultimately the organization's financial investment. Historically, most oil companies rely on the latest production test done at the actual choke to calculate the produced volume per string, regardless of changes in well performance over time. But this simplistic routine leaves a gap between estimated and actual rates that require more user interventions for manual inputs or corrections.
This paper illustrates an example of hydrocarbon allocation process from a smart field. An intelligent optimization system that receives real time data instantly automatically back allocates the field rate based on continuously-tuned well performance curves at wellhead node. This system is capable of managing large amount of data as well as combining analytical models, data mining with predictive analytics, bringing significant benefits to reservoir management, and surveillance process. However, it was found that the field correction factor fluctuated about 25%, when some production optimization and well operations were performed due to inconsistencies in well performance curves.
The traditional methodology to calibrate well models starts by choosing the nearest multiphase flow vertical correlation to the measured pressure gradient, reducing the error between calculated and measured points by tuning the "L factor." This procedure cannot ensure that the resulting model will satisfy other production tests at different flowing conditions, which reveals the difference between accuracy and consistency. In contrast, the present effort suggests a practical approach for better estimation of daily well rates as well as improving allocation process, since it attempts to minimize the error between representative production tests and well performance curve rather than reproduce a high accurate bottom hole pressure for a particular flowing condition. Additionally, a more representative productivity index is derived from this change.
This novel approach showed better well rate estimation for different flowing conditions reducing reassignment factor deviation below 5%. Consequently, it proved that having a more consistent well model tuned by representative production tests and controlled by real time data, enhances oil back allocation process.
Smart Condition Monitoring Using Machine Learning
Authors: Bangert Patrick 
Published: May 2017

Abstract
Condition Monitoring usually analyzes each measurement separately using static limit information. This results in false alarms and unhealthy conditions that are not alarmed. Using machine learning techniques, the big data gathered around large equipment or an entire plant can be analyzed as a single coherent whole to draw conclusions about its current state of health. First, a mathematical model of the relevant measurement is created using the other measurements available. This model represents the equipment or plant as a unit when it is operating as it should. Second, this expected value is compared to the measured value. If they agree, the current state is healthy. If they do not, an alarm is released and a maintenance activity must follow. This method is seen to be far more successful than standard condition monitoring thus preventing false alarms and always alarming unhealthy states.
Influence of intermittent water supply operations on the vulnerability of water distribution networks
Authors: Agathokleous Agathoklis , Christodoulou Chrystalleni , Christodoulou Symeon E. 
Published: May 2017

Abstract
Water authorities in countries facing water shortage problems are implementing intermittent water supply (IWS) policies, as a measure to conserve and control their national water resources. Implementation of such measures affects the behaviour of the water pipe systems during the operation stage. The research work presented herein presents a model simulating the behaviour of urban water distribution networks (WDNs) under normal operating conditions, as well as during a period of IWS operations. The modelling and analysis, based on an eight-year dataset (2003–2010) from a local Water Board, takes into account information related to breakage incidents within the WDN as well as external factors to perform vulnerability assessment of the pipe network. The results of the performed survival and cluster analysis show that during the implementation period of IWS operations, and right after that period, there is a significant increase in the deterioration rate of the affected network. Further, there is a change in the comparative importance of the factors affecting the network condition and their contribution to the WDN vulnerability.

Communication News Briefs Promising developments in communicating to the deaf were discussed by Minister of Communications Jeanne Sauve at a recent national convention of the Canadian Cultural Society of the Deaf. The Federal Government at a total cost of $700, 000, is sponsoring the development of a device known as the Visual Ear. This portable equipment about the size of a hard cover book makes it possible for those with difficulty in speech and hearing to use telephones. Messages are typed on a small keyboard and then displayed on a similar device connected to the telephone of the party being called. The Visual Ear is expected to be available early next year at an estimated cost of $300-$400.
The Daily Newspaper: Mirror Of Our Myths
Authors: De Repentigny Michel 
Published: May 2017

The object of this paper is to demonstrate that if it can be said, as a general rule, that Quebec's daily newspapers - and this observation is no doubt true also of Canadian and American dailies - do not grant news or information from the Third world much importance, it should not be taken for granted that trying to improve this situation will contribute significantly to the advent of a new world order of information, that it will do justice to the real and huge problems hindering the production and circulation of information in developing countries. Obviously, the commercial aspects of the news market in Western countries bear heavily on the 'social vocation' of newspapers. The intimate structural ties between these two orders of necessity are such that not much can be done to have newspapers offer their readers, in a sustained way, instructive information on the development processes of the Third world instead of supplying, often in a haphazard way, news which entertains or shocks. A realistic approach, then, to these problems requires that a basic fact be taken into account: namely that what is most urgently needed in Third world countries are infrastructures that could generate and disseminate information horizontally among their inhabitants and those of other underdeveloped countries; much more so, it seems to me, than a more balanced flow of news between North and South. Concretely, this implies that it is more important for people living in remote Senegalese villages to be adequately informed about agricultural techniques suited to their specific needs, than for me to be informed by a news dispatch coming from an African news agency, that Senghor has just published a new collection of poems.

Energy has become a detrimental factor for survival and progress of anthropology. For the past decade, we have become totally dependent on unlimited and continuous supply of electrical energy. However, the generation of such huge amount of electrical energy is done from nonrenewable sources of energy like coal, oil gas etc. This way of producing electricity involves heavy consumption of non-conventional sources of energy and has given rise to the ominous problem of global warming. Thus, energy conservation has become an important concern all over the world. Switching to the use of renewable sources like solar, wind and hydro energy has become a recent trend. This is the reason why our project, aims to maximise the use of solar energy by analyzing the present system such that it can be beneficial for the economy of our country. The analysing process is done using the smart meter, which captures the readings on an hourly basis.
