Published: January 2017

We conducted a longitudinal community-based survey between August 1991 and August 1992 started with a pilot study in May 1991 in two rural villages which involved 497 children aged 0-59 monhs, 58 community health workers (CWHs), 44 community representatives, and 5 health center personnel. The qualitative component was carried out using in-depth interviews with the mothers, CWHs, and health personnel. It appeared that the three terms for diarrhea used in thecommunity were similar to medical terminology. However the community perception was that only cases of diarrhea with dehydration should be referred to the health center (HC) for tretment; bloody diarrhea was not considered to be referred. Through case findings, 168 (33.8%) diarrheal episodes were identified among 141 children (1.2 episodes per child). Twenty-two of 168 cases (13.1%) had bloody stool, shigella was isolated in 9 (41%) of these patients. No death occurred in this study. Diagnostic agreement on bloody and watery stool specimens between HC personnel and CHWs was analyzed using data from the 72 stool specimens that were seen by both parties, which showed a kappa coefficient of 0.50. Breast feeding (90%) nand additionalk food (89%) were given during diarrhea in almost all cases. Oral rehydration salts solution was given in 80% odf cases. The study shows that the existing treatment guidelines in the HCs were not properly followed by the health personnel.

The aims of the study were to review the clinical features of patient with suspected typhoid fever, to obtain features of the blood culture results, Widal, Typhidot tests and to identify the relationship between/prior antibiotic administration with laboratory findings. The study had been conducted since January 1, 1999 till January 31, 2000 with inclusion criteria (1) age of patient was 3 to 14 years, (2) patient with diagnosis of suspected typhoid fever and (3) gave consent to participate in the present study. Thirty-six patients were eligible for this study and the result showed that typhoid fever was encountered more commonly in girls with the most prevalent onset was in age 5 to 9 years and duration of fever was less than 8 days. Gastrointestinal tract disturbance was the most frequent complain after fever. Most patient showed negative results in blood culture examination and Widal test, and gave positive results in Typhidot/Typhidot M test as well. Antibiotic administration tended to influence blood culture and Widal test as to need consideration in evaluation of laboratory results. However, a conclusion still could not be drawn definitively that further study with adequate sample number and positive blood culture as criteria inclusion was needed.
Reliability and failure functions of some weighted systems
Authors: Nashwan Imad 
Published: January 2017

In modern systems, not only the number and the position of the functioning or the failed components are the main factors that keep the system into the functioning state or transform it into failure state, but the contribution or the working probability of the component is also a very important one. This contribution is usually called the component weight. In this paper, the reliability and the failure functions of the consecutive weighted k-out-of-n: F linear and circular system, the weighted f-out-of-n: F system, the weighted Â (n,f,k) linear and circular system and the weighted Â linear and circular system are obtained.

Wittgenstein’s Thought-Experiments
Authors: Miščević Nenad 
Published: January 2017

AbstractWittgenstein’sOne immediate result of comparing Wittgenstein’s thought-experiments with their counterparts in the analytic mainstream reveals an interesting trait: they are merely suggestive, in the sense that the theses they point to are rarely put forward explicitly, and even more rarely argued for in the manner that is nowadays fashionable in the mainstream. The paper briefly points to the difference by using the examples of Saul Kripke’s (1982) presentation of Rule-following and the unorthodox reading of the Builders by Charles Travis (1989), to illustrate the potential of the merely suggestive material for re-interpretation by a creative thinker.
Wittgenstein as a Common-Sense Realist
Authors: Nyíri Kristóf 
Published: January 2017

AbstractThe later Wittgenstein is widely held to be a relativist, indeed a constructivist. By contrast, this paper argues that all appearances to the contrary Wittgenstein was a realist, and that this fact becomes almost conspicuous in his late-1940s manuscripts. His realism was a common-sense one, the only kind of realism worthy of the name. Wittgenstein’s common-sense realism has unique traits: first, an uncompromising stress on deviations from ordinary language as a source of (bad) philosophy. Secondly, his awareness of the significance of the pictorial & the motor. Thirdly, his emphasis on established use, that is, on traditions. In the later Wittgenstein, philosophical realism and social conservatism converge.
Philosophy from an ‘Anthropological’ Point of View
Authors: Munz Volker A. 
Published: January 2017

AbstractIn this paper I shall try to introduce a few aspects on the possible influence Piero Sraffa had on Wittgenstein’s later philosophy. Although we do not have many explicit sources, we find a few remarks in Wittgenstein’s manuscripts that contain Sraffa’s name in brackets. And interestingly enough they almost all deal with the fundamental relation between rules and empirical propositions. Wittgenstein raises questions such as: Do grammatical rules only say that words are actually used in a particular way? Do mathematical propositions describe how human beings usually calculate? Are the rules of chess descriptions of how the game has always been played? Wittgenstein’s discussions of these questions also had an impact on his philosophical turn towards an ‘anthropological’ point of view.

Published: January 2017

Abstract
In this paper we analyze the influence of users’ density distribution in one cell of CDMA mobile network (ie adjusted power control on the forward link) on base station emission power. This influence is analyzed for different circles radii around base station within which same emission power is generated for all mobile users, and for different values of propagation loss coefficient. It is proved that emission power in this cell must be increased comparing to the similar cell, which uses complete power control. The power increase is greater when greater number of users are situated near base station, and for greater values of propagation loss coefficient. The results are presented, illustrated by numerical examples and verified by simulation for three users’ density distributions: uniform, decreasing and increasing density from the base station to the cell rim. The simulation process, which is based on random traffic process, is presented briefly.
Impact of the Cooling Equipment on the Key Design Parameters of a Core–Form Power Transformer
Authors: Orosz Tamás , Tamus Zoltán Ádám 
Published: January 2017

Abstract
The first step in the transformer design process is to find the active part’s key design parameters. This is a non-linear mathematical optimisation task, which becomes more complex if the economic conditions are considered by the capitalisation of the losses. Geometric programming combined with the method of branch and bound can be an effective and accurate tool for this task even in the case of core-form power transformers, when formulating the short-circuit impedance in the required form is problematic. Most of the preliminary design methods consider only the active part of the transformer and the capitalised costs in order to determine the optimal key design parameters. In this paper, an extension of this meta-heuristic transformer optimisation model, which takes the cost of the insulating oil and the cooling equipment into consideration, is presented. Moreover, the impact of the new variables on the optimal key design parameters of a transformer design is examined and compared with the previous algorithm in two different economic scenarios. Significant difference can be found between the optimal set of key-design parameters if these new factors are considered.

Published: January 2017

Abstract
In this paper, the analysis of ice-shedding from ACSR conductors to its swing up height and vibration using Finite Element Method (FEM) is presented. For the numerical simulations the effective material properties of the ACSR conductor are calculated using the homogenisation method. Numerical analysis concerning vibration of one and triple-bundle conductors with icing for a whole range or on their certain parts are performed. The impact of ice-shedding to the mechanical tension in the conductors at the points of attachment is investigated and evaluated. Identification of the impact of ice-shedding from the ACSR conductors on its mechanical state may contribute to increasing the safety and quality of an electrical transmission system.

Published: January 2017

Abstract
A detailed numerical study on structure of symmetric tilt grain boundaries in α-iron is presented. The study is focused on structural and energetic optimization of 〈100〉 grain boundaries Σ5(210), Σ5(310), Σ17(410) and Σ13(510). Particular attention is given to grain boundary reconstruction, which is characterized by increased atomic density in grain boundary plane compared to bulk. The results of our numerical experiments significantly improved our knowledge about the migration of atoms between planes perpendicular as well as parallel to GB plane as an essential part of grain boundary reconstruction.
Low Power Consumption Digital Clock Recovery Circuit Based on Threshold Crossing
Authors: Perić Dragana , Perić Miroslav 
Published: January 2017

Abstract
In this paper a new structure of digital clock recovery — DCR circuit is presented. The main features of this DCR are: low complexity design, low power consumption and a single system clock operation. Thus, multiple instantiation of this type of DCR on a single chip is not complex. Due to this, such DCR can target application in energy-efficient cognitive radio systems with carrier aggregation. For performance evaluation, we have derived Markov chain based mathematical model for peak-to-peak and root mean square jitter performance analysis. The stability problem of this model, rising from the fact that some phase error states have several orders of magnitude lower probabilities than the others, is solved using mathematical apparatus for symbolic analysis. The mathematical model validity is examined by laboratorial measurements of proposed DCR for 4-PAM signal. The measurement methodology and results are described in details.

Authors: Ping Cheng , Jiaqun Zhao 
Published: January 2017

Abstract
To improve the performance of inverse synthetic aperture radar (ISAR) imaging based on compressed sensing (CS), a new algorithm based on log-sum minimization is proposed. A new interpretation of the algorithm is also provided. Compared with the conventional algorithm, the new algorithm can recover signals based on fewer measurements, in looser sparsity condition, with smaller recovery error, and it has obtained better sinusoidal signal spectrum and imaging result for real ISAR data. Therefore, the proposed algorithm is a promising imaging algorithm in CS ISAR.

Authors: Zor Ömer 
Published: January 2017

Abstract
The duality transformation was used to define the polarization mechanisms that arise from magnetic monopoles. Then, a dimensional analysis was conducted to describe the displacement and magnetic intensity vectors (constitutive equations) in SI units. Finally, symmetric Maxwell equations in a material medium with new field quantities were introduced. Hence, the Lorentz force and the Poynting theorem were defined with these new field quantities, and many possible definitions of them were constructed.
A Method for Continuous Tuning of MOSFET–RC Filters with Extended Control Range
Authors: Kiela Karolis , Navickas Romualdas 
Published: January 2017

Abstract
In this paper a tuning structure for a MOSFET?RC filters is presented. The proposed tuning structure is composed of switched resistor banks with voltage controlled transistors. The voltage controlled transistors use active feedback with extended control range for continuous filter parameter tuning, without degrading the total linearity performance of the filter. The proposed tuning structure is tested by implementing it in a second order low pass biquadratic filter cell in 65 nm CMOS technology. The designed filter has a highly reconfigurable response, ranging from Chebyshev to Bessel, a tuneable -3 dB bandwidth from 10 MHz to 100 MHz and can be used for multiple standard wireless solutions. Filter IIP3 performance is not degraded when the bandwidth is continuously tuned by 40 % with a 1 V pp input. The maximum power dissipation, including active feedback circuits, is 17.2 mW from a 1.2 V source when the filter is tuned to 100 MHz bandwidth.

Published: January 2017

Abstract
Patterning of metal oxide nanostructures with different shapes and well-defined size may play an important role in the improvement of MEMS systems, sensors and optical devices. We investigated the effects of HSQ e-beam resist processing on the fabrication of sputtered TiO2 nanostructures. They were patterned using direct write e-beam lithography combined with ICP-RIE etching in CF4/Ar plasma. Experimental results confirmed that the HSQ resist with a thickness of about 600 nm is suitable as a masking material for optimal etching process and allows patterning of the dots array in TiO2 sputtered films with a thickness up 150 nm. TiO2 arrays with a minimal dots diameter of 180 nm and spacing of 1000 nm were successfully developed.
Flood Risk in Szeged before River Engineering Works: A Historical Reconstruction
Authors: Szalontai Csaba 
Published: January 2017

Abstract
Szeged situated at the confluence of the Tisza and the Maros Rivers has been exposed to significant flood risk for centuries due to its low elevation and its location on the low floodplain level. After the Ottoman (Turkish) occupation of Hungary (ended in 1686), secondary sources often reported that the town was affected by devastating floods which entered the area from north, and a great part of the town or its whole area was inundated. Natural and artificial infill reduced the flood risk to some extent after the town had been founded, but in the 19th century flood risk was mitigated by river engineering and the reconstruction of the town. The town relief was raised by a huge amount of sediment, which makes it difficult to determine the elevation of the original relief as well as the exact flood risk of the study area. However, some engineering surveys originating from the 19th century contain hundreds of levelling data in a dense control point network making possible to model the relief of the whole town preceding its reconstruction and ground infill. Based on these data, we prepared a relief model which was compared with the known data of the 1772 flood peak, from which we deduced that 60% of the town must have been inundated before it was filled up. As there could have been 50-100 cm thick natural or artificial ground infill since the 11th century, the original natural relief can be gained by deducting these data. Based on this deduction, the extent of inundation centuries ago could reach 85%, which means almost total flooding.
Image Based Surface Temperature Extraction and Trend Detection in an Urban Area of West Bengal, India
Authors: Ziaul Sk , Pal Swades 
Published: January 2017

Abstract
Rapid urbanization and change of landuse/landcover results in changes of the thermal spectrum of a city even in small cities like English Bazaar Municipality (EBM) of Malda district. Monitoring the spatio-temporal surface temperature patterns is important, therefore, the present paper attempts to extract spatio-temporal surface temperature from thermal band of Landsat imageries and tries to validate it with factor based Land Surface Temperature (LST) models constructed based on six proxy temperature variables for selected time periods (1991, 2010 and 2014). Seasonal variation of temperature is also analyzed from the LST models over different time phases. Landsat TIRS based LST shows that in winter season, the minimum and maximum LST have raised up 2.32°C and 3.09°C in last 25 years. In pre monsoon season, the increase is much higher (2.80°C and 6.74°C) than in the winter period during the same time frame. In post monsoon season, exceptional situation happened due to high moisture availability caused by previous monsoon rainfall spell. Trend analysis revealed that the LST has been rising over time. Expansion and intensification of built up land as well as changing thermal properties of the urban heartland and rimland strongly control LST. Factor based surface temperature models have been prepared for the same period of times as done in case of LST modeling. In all seasons and selected time phases, correlation coefficient values between the extracted spatial LST model and factor based surface temperature model varies from 0.575 to 0.713 and these values are significant at 99% confidence level. So, thinking over ecological growth of urban is highly required for making the environment ambient for living.

Published: January 2017

Abstract
The Retezat Mountains, located in the Southern Carpathians, are one of the highest massifs in Romania and home of the Retezat National Park, which possesses an important biological value. This study aimed at the investigation of water quality in creeks of the Southern Retezat (Piule-Iorgovanul Mountains) in order to provide information on pollutants of both natural and anthropogenic origin, which could pose a threat for the human health. Heavy metal and other inorganic ion contents of samples were analyzed with on-site and laboratory measurements to estimate water quality. The samples were investigated using microwave plasma - atomic emission spectrometry to quantify specific elements, namely aluminium, cadmium, cobalt, chromium, copper, iron, magnesium, manganese, molybdenum, nickel, lead and zinc. The results were compared with the European Union and Romanian standards regarding drinking water and surface water quality. The studied heavy metals have been found to be in very low concentrations or under the method’s detection limit. Thus, in the microbasin corresponding to the sampling points, there seems to be no heavy metal pollution and, from this point of view, the samples comply as drinking water according to the European Union and Romanian recommendations. Our findings confirm that the Retezat Mountains are still among the least contaminated regions in Europe and that the ecosystem and the human health is not negatively influenced by water quality problems.
