Authors: He Yu-Ling , Ke Meng-Qiang , Tang Gui-Ji , Jiang Hong-Chun , Yuan Xing-Hua 
Published: November 2016

Abstract
The intent of this paper is to investigate the effect of the interturn short circuit fault (ISCF) in rotor on the magnetic flux density (MFD) of turbo-generator. Different from other studies, this work not only pays attention to the influence of the faulty degrees on the general magnetic field, but also investigates the effect of the short circuit positions on the harmonic components of MFD. The theoretical analysis and the digital simulation through the FEM software Ansoft are performed for a QSFN-600-2YHG turbo-generator. Several significant formulas and conclusions drawn from the analysis and the simulation results are obtained to indicate the relation between the harmonic amplitude of the MFD and the faulty degree (via nm
, the number of the short circuit turns), and the relation between the MFD harmonic amplitude and the faulty position (via αr
, the angle of the two slots in which the interturn short circuit occurs). Also, the developing tendency of the general magnetic field intensity, the distribution of the magnetic flux lines, and the peak-to-peak value of MFD are presented.

Published: November 2016

Abstract
This paper proposes an adaptive current control method for Hybrid Active Power Filter (HAPF). It consists of a fuzzy-neural controller, identification and prediction model and cost function. The fuzzy-neural controller parameters are adjusted according to the cost function minimum criteria. For this reason, the proposed control method has a capability on-line control clings to variation of the load harmonic currents. Compared to the single fuzzy logic control method, the proposed control method shows the advantages of better dynamic response, compensation error in steady-state is smaller, able to online control is better and harmonics cancelling is more effective. Simulation and experimental results have demonstrated the effectiveness of the proposed control method.

Authors: Sadeghi Hassan , Ghaffarzadeh Navid 
Published: November 2016

Abstract
This paper uses a new algorithm namely biogeography based optimization (BBO) intended for the simultaneous placement of the distributed generation (DG) units and the capacitor banks in the distribution network. The procedure of optimization has been conducted in the presence of nonlinear loads (a cause of harmonic injection). The purpose of simultaneous optimal placement of the DG and the capacitor is the reduction of active and reactive losses. The difference in the values of loss reduction at different levels of the load have been included in the objective function and the considered objective function includes the constraints of voltage, size and the number of DG units and capacitor banks and the allowable range of the total harmonic distortion (THD) of the total voltage in accordance with the IEEE 519 standards. In this paper the placement has been performed on two load types ie constant and mixed power, moreover the effects of load models on the results and the effects of optimal placement on reduction of the THD levels have also been analyzed. The mentioned cases have been studied on a 33 bus radial distribution system.

Published: November 2016

Abstract
In this work, an amorphous alloy with the nominal composition of Fe78Si9B13 was produced by a melt spinning method. Using different velocities of a quenching cooper wheel enabled us to study the influence of quenching rate upon the structural characteristics of the resulting ribbons. Structural features of the samples were checked by Mössbauer spectroscopy and X-ray diffraction. The latter performed in a grazing angle geometry enabled us to explore both sides of the as-quenched ribbons. The onset of crystallization was estimated by differential scanning calorimetry (DSC) measurements. Surface features of the ribbons were examined by Scanning Electron Microscopy (SEM). In order to observe structural relaxation phenomena the samples were annealed below the onset of crystallization at 450 °C for 1 hour in Ar protective atmosphere. Even though the annealed ribbons are still amorphous relevant changes were observed in their hyperfin parameters as derived from Mssbauer spectrometry.
A Novel Subcarrier Allocation Algorithm for MC–CDMA Systems
Authors: Seyman Muhammet Nuri , Saçakli Bircan 
Published: November 2016

Abstract
Multi carrier modulation techniques such as MC-CDMA are used in high-speed communication applications. Due to MC-CDMA being a multiuser in technology, the subcarrier quantity allocated per user decreases in case the quantity of active users increases. Consequently, data rates per user are reduced with the increase in the bit error rate (BER). Efficient allocation of subcarriers to users within the system can aid the overcoming of this problem. This study develops a new algorithm for subcarrier allocation and system performance improvement in terms of BER, and data rates in comparison to other algorithms were ensured.

Abstract
This paper is dedicated to electro-physical characterisation of a GaAs p-i-n structure grown for solar cell applications, which was carried out by light and dark current-voltage (I–V) and Deep Level Transient Fourier Spectroscopy (DLTFS) methods. The conversion efficiency and open-circuit voltage were determined from I–V measurement at 1 and 20× sun light concentrations. Three electron like defects TAn1, TAn2, TDn and one hole like defect TBp obtained by DLTFS measurements were confirmed. The origin of these defect states was stated as native GaAs impurities.
Comparative Electromagnetic and Quasi–Static Simulations of a Shortpulse Propagation along Microstrip Meander Delay Lines with Design Constraints
Authors: Orlov Pavel , Gazizov Talgat , Zabolotsky Aleksander 
Published: November 2016

Abstract
A numerical analysis of microstrip meander delay lines is considered. Results of quasi-static and electromagnetic simulations are given. It is shown that when increasing a number of turns and proportionally reducing their length, distortions of a pulse signal in the line are reduced. At the same time, despite structure’s electrical width increase, the agreement between the results of quasi-static and electromagnetic analyses is improved. Thus, it is demonstrated that when designing the microstrip meander delay lines with minimal distortions, the quasi-static analysis is relevant.

Authors: Singh Mehtab , Singh Navpreet 
Published: November 2016

Abstract
In this paper, simulative analysis and performance comparison of different EDFA (Erbium-doped fiber amplifier) configurations in a 10 Gbps inter-satellite optical wireless communication (IsOWC) link have been reported for a 5,000 km long link and 1,550 nm operating wavelength. The results show that system in which both pre-amplifier and booster amplifier stages are implemented simultaneously outperforms systems with only pre-amplifier and booster amplifier stage. From the results, it can be seen that by deploying a transmission power level of 15 dBm, a link distance of 9,600 km can be achieved with a quality factor of 6.01 dB and BER (Bit error rate) of

). Also, the effect of channel spacing on the performance of WDM-IsOWC link is investigated. The results show that the received signal has acceptable performance levels when the channel spacing is 100 GHz but when the channel spacing is reduced to 80 GHz, the quality of the received signal degrades and link distance decreases.
Research on Segmentation Monitoring Control of IA-RWA Algorithm with Probe Flow
Authors: Ren Danping , Guo Kun , Yao Qiuyan , Zhao Jijun 
Published: November 2016

Abstract
The impairment-aware routing and wavelength assignment algorithm with probe flow (P-IA-RWA) can make an accurate estimation for the transmission quality of the link when the connection request comes. But it also causes some problems. The probe flow data introduced in the P-IA-RWA algorithm can result in the competition for wavelength resources. In order to reduce the competition and the blocking probability of the network, a new P-IA-RWA algorithm with segmentation monitoring-control mechanism (SMC-P-IA-RWA) is proposed. The algorithm would reduce the holding time of network resources for the probe flow. It segments the candidate path suitably for the data transmitting. And the transmission quality of the probe flow sent by the source node will be monitored in the endpoint of each segment. The transmission quality of data can also be monitored, so as to make the appropriate treatment to avoid the unnecessary probe flow. The simulation results show that the proposed SMC-P-IA-RWA algorithm can effectively reduce the blocking probability. It brings a better solution to the competition for resources between the probe flow and the main data to be transferred. And it is more suitable for scheduling control in the large-scale network.

Authors: Pakdehi Shahram G. , Rasoolzadeh Maryam , Moghadam Ali Saberi 
Published: November 2016

Abstract
This research concentrated on the structural stability of γ-alumina (γ-Al2O3) was investigated by a combination of differential thermal analysis, X-ray diffractometry and surface-area measurements. The γ –to– θ and then α phase transitions were observed as an exothermic peak at 1000°C–1400°C in the DTA curves. The role of barium oxide as a modifier to stabilize γ-Al2O3 structure has been investigated. XRD measurements show that after calcination at 1000°C for 2 h, a significant fraction of the pure γ-Al2O3 (BaO-free) transformed to θ-Al2O3 while that the transition phase in alumina samples modified by BaO have been reduced significantly. Barium oxide, eliminate pentacoordinated aluminum ions through coordinative saturation and alter these ions into octahedral cations and effectively suppressed the γ –to– α phase transition in Al2O3, which concluded as improving the thermal stability and porous properties of the experimental samples.

AbstractBreast cancer often requires combined oncologic treatments, the base of which is surgery. Quality of life (QoL) after each surgical procedure may influence the process of decision making among women, who qualify for multiple oncological strategies. Our knowledge about QoL in breast cancer patients is derived from comparative studies. Results may differ, depending on country, culture, and societal relations.was to investigate the quality of life of Polish patients treated with breast-conserving therapy (BCT) or mastectomy with breast reconstruction.The study involved women who underwent surgery for breast cancer in the Department of Surgical Oncology of the Gdynia Oncology Center from September 2010 to November 2013. Eighty-two breast reconstructions (in 79 patients) and 226 BCT procedures were performed. QoL was measured with the use of EORTC QLQ-C30 and QLQ-BR23 questionnaires.Global QoL was high in both groups and did not differ significantly. Body image was slightly better after BCT than after mastectomy with breast reconstruction, but sexual QoL was lower. Future perspective was quite low in both groups. Disease symptoms were not bothering.The global QoL among Polish breast cancer patients treated with BCT or mastectomy with breast reconstruction is high and does not differ between groups. There is a need for anxiety and disease-related fear prophylaxis and for the improvement of sex life of breast cancer survivors.

Published: November 2016

AbstractThis study presented a septic shock occurring with striking speed during the percutaneous drainage of a large abscess of the liver in an 18-year-old female patient after an appendectomy performed 3 months earlier using the laparoscopic method because of its phlegmonous and gangraenosus inflammation. The post-operative course was complicated by increased suppuration in places after removal of the trocars. After including the intravenous antibiotic therapy and under the USG control, the percutaneous drainage of the abscess was performed. While withdrawing the guide of the drainage catheter set, the symptoms of septic shock occurred. The pharmacological treatment was applied with continuation of the antibiotic therapy till a negative result of microbiological tests was obtained and the normalization of life parameters. The patient was not qualified for treatment in the ICU. She was discharged in a generally good condition after 24 days of hospitalization. In the case of this patient, the drain covered with the content of the abscess may have contact with the adjacent tiny blood vessels, which may have contributed to the systemic inflammatory response syndrome that was linked with fast-developing sceptic shock.

Authors: Popa F. , Alexescu C. , Popa B. 
Published: November 2016

AbstractIn Romania, there are no pumped storage plants (PSPs) significant from the point of view of the National Power System (NPS). For more than 30 years, one site is expected to achieve 1000 MW PSP, using the existing reservoir Tarnita, on Somes river, as the lower reservoir. Recently, Hidroelectrica launched a study identifying new potential sites for PSPs in the Eastern part of Romania, where there is a huge development for wind farms and where Cernavoda nuclear power plant is located, with 2 units of 700 MW each in operation and other 2 units to be built until 2035. These PSPs will cover the ancillary services and, according to a new Government Ordinance, will enable a better integration of the existing RES into the NPS, and will increase the generation of electricity from RES by their own production of electricity.

Authors: Bagińska Irena , Kawa Marek , Janecki Wojciech 
Published: November 2016

Abstract
The paper deals with application of CPTu test results for the probabilistic modeling of dumping grounds. The statistical measures use results from 42 CPT test points located in the lignite mine dumping ground from the region of Central Europe. Both the tip resistance qc
as well as local friction fs
are tested. Based on the mean values and standard deviations of measured quantities the specific zones in the dumping site profile are distinguished. For three main zones standard deviations of linearly de-trended functions, distributions of normalized de-trended values for qc
and fs
are examined. Also the vertical scales of fluctuation for both measured quantities are estimated. The obtained result shows that lignite mine dumping site can be successfully described with the Random Field Theory. Additional use of fs
values introduces supplementary statistical information.

A close matching of the two is observed.
The influence of normal fault on initial state of stress in rock mass
Authors: Tajduś Antoni , Cała Marek , Tajduś Krzysztof 
Published: November 2016

Abstract
Determination of original state of stress in rock mass is a very difficult task for rock mechanics. Yet, original state of stress in rock mass has fundamental influence on secondary state of stress, which occurs in the vicinity of mining headings. This, in turn, is the cause of the occurrence of a number of mining hazards, i.e., seismic events, rock bursts, gas and rock outbursts, falls of roof. From experience, it is known that original state of stress depends a lot on tectonic disturbances, i.e., faults and folds. In the area of faults, a great number of seismic events occur, often of high energies. These seismic events, in many cases, are the cause of rock bursts and damage to the constructions located inside the rock mass and on the surface of the ground. To estimate the influence of fault existence on the disturbance of original state of stress in rock mass, numerical calculations were done by means of Finite Element Method. In the calculations, it was tried to determine the influence of different factors on state of stress, which occurs in the vicinity of a normal fault, i.e., the influence of normal fault inclination, deformability of rock mass, values of friction coefficient on the fault contact. Critical value of friction coefficient was also determined, when mutual dislocation of rock mass part separated by a fault is impossible. The obtained results enabled formulation of a number of conclusions, which are important in the context of seismic events and rock bursts in the area of faults.
