The present work is devoted to study the microstructure and magnetic behavior of Mn-rich Heusler MnNiIn alloys. The Mn-substituted alloys with Mn50Ni50-xInx (at.%) (x = 7.5 and 10) were prepared by melt-spinning technique. Experimental results show that the alloys crystallized into a monoclinic martensite structure 14M type, for the Mn50Ni42.5In7.5 alloy and L21 type cubic austenite structure for the Mn50Ni40In10 alloy. The characteristic temperatures decreased with the increase of In content under different magnetic fields: 50 Oe, 500 Oe, 5 kOe and 30 kOe. For the Mn50Ni42.5In7.5 alloy, the presence of a paramagnetic-ferromagnetic transition is noted. This transition in the austenitic phase occurs before the martensitic transformation during cooling. On the other side, for the Mn50Ni40In10 alloy, there is the presence of a martensitic transformation followed by a ferromagnetic transition. This transformation is carried out between a paramagnetic cubic austenite type and a ferromagnetic monoclinic martensite. This allows us to conclude that Indium addit ion plays a role to change the structure and magnetic behavior in MnNiIn alloys.

In this paper, a robust technique based on discrete wavelet transform, edge detection, and morphology operation for scene text detection is proposed. There are several stages in the proposed method. In the first stage, a single wavelet decomposition LH, HL and HH subbands are applied for detecting edges in original scene text image. The projection technique is applied in the second stage to preliminary detect text and non-text pixels. In third stage, 4-connected components are applied, and then area geometric feature is used as threshold to remove non-text region. At last stage, morphological operations are applied to connect isolated text components and to remove non-text regions. The proposed method is applied on a various images such as images of low contrast, complex background images and images of different fonts and size of text. The experimental results show that the proposed method can detect regions of the text perfectly. © 2016 The Authors

In this work, an attempt has been made to join the AA6082-T651 and AA7075-T651 aluminium alloys by friction stir welding (FSW). The FSW is a solid-state joining process which primarily used on aluminium because the metal is not melted during the process so the base material can not soften. For the welding were using cylindrical pin tool, marble table to avoid the harmful heat conduction, two rotation rate of 500 and1000 rpm and different traverse speeds of 15, 20, 25 and 30 mm/min to weld butt joints. The aim of present study were to experimentally explore the dissimilar bounds. For evaluations, hardness testing were using to create hardness profiles across the joint in through thickness direction and optical microscope to classify the microstructures and crystallographic textures of base materials (BM). Based on the results obtained it can be stated that the FSW suitable for AA7075 and AA6082 welding by further optimization of the process parameters.

Due to of the bandwidth constraint, sensors may only be able to transmit a finite number of bits to save the energy, and the measurement data may have to be quantized before transmission especially in wireless sensor networks (WSNs). This paper studies the problem of the general quantized innovation filtering with random packet dropouts for linear stochastic uncertain systems. The multiplicative uncertainty of system parameters is first converted into additive noises. Then under the Gaussian assumption on the predicted density, the Lloyd-Max quantizer, a general quantized innovation filter with random packet dropouts in the linear minimum mean square error (LMMSE) sense is derived based on the projection theory and Bayes Rule. Furthermore a sufficient condition is provided, under which a general quantized innovation filter with random packet dropouts can be reduced into a standard Kalman filter. An example is simulated to illustrate the effectiveness and correctness of the designed filter.

This computational study analyses the pulsatile flow of blood in a narrow artery with mild asymmetric stenosis, treating the blood flow as two-layered model with the suspension of all the erythrocytes in the core layer region as Casson fluid and the cell dep.eted plasma in the peripheral layer region as Newtonian fluid. Finite difference method is employed to solve the resulting system of non-linear partial differential equations along with a set of initial and boundary conditions. Explicit finite difference scheme is derived for velocity profile, flow rate, wall shear stress and longitudinal impedance to flow. It is noted that skin friction and longitudinal impedance to flow increase with the increase of yield stress, Hartmann number and stenosis dep.h. The aforementioned fluid behaviour is reversed to the velocity profile and flow rate when these parameters increase. It is found that the longitudinal impedance to flow for the two-fluid Casson model is considerably lower than that of the single-fluid Casson model.

Autonomous photovoltaic systems have already been proved as one of the most reliable ways to handle the electrification requirements of remote consumers in isolated areas. The technology improvement in the field of building integrated photovoltaic systems, along with the governmental financial incentives for boosting the corresponding energy sector, have increased the interest of installing small scale photovoltaic systems not only in remote dwellings but also in grid-connected households. The penetration of photovoltaic systems in densely populated areas has made people even more familiar with them and therefore people with environmental consciousness are more likely to adopt the specific technology. In this context, the present work aims in highlighting the capabilities of building integrated photovoltaic systems along with battery storage devices in covering the electrical needs of a typical dwelling using real electricity demand and meteorological data based on Typical Meteorological Year time series. The system is simulated on an hourly basis by using an integrated numerical code that has been developed by the Soft Energy Applications & Environmental Protection Laboratory of the Mechanical Engineering dep.. of Piraeus University of Applied Sciences in Greece. The proposed solution guarantees zero load rejections under different solar potential schemes investigating also the possibilities of minimizing the storage system capacity.

Selecting the most suitable local invariant feature detector for a particular application has rendered the task of evaluating feature detectors a critical issue in vision research. Although the literature offers a variety of comparison works focusing on performance evaluation of image feature detectors under several types of image transformations, the influence of the scene content on the performance of local feature detectors has received little attention so far. This paper aims to bridge this gap with a new framework for determining the type of scenes which maximize and minimize the performance of detectors in terms of repeatability rate. The results are presented for several state-of-the-art feature detectors that have been obtained using a large image database of 20482 images under JPEG compression, uniform light and blur changes with 539 different scenes captured from real-world scenarios. These results provide new insights into the behavior of feature detectors. Copyright © 2017, The Authors. All rights reserved.

Quantum computers offer an intriguing path for a paradigmatic change of computing in the natural sciences and beyond, with the potential for achieving a so-called quantum advantage, namely a significant (in some cases exponential) speed-up of numerical simulations. The rapid development of hardware devices with various realizations of qubits enables the execution of small scale but representative applications on quantum computers. In particular, the high-energy physics community plays a pivotal role in accessing the power of quantum computing, since the field is a driving source for challenging computational problems. This concerns, on the theoretical side, the exploration of models which are very hard or even impossible to address with classical techniques and, on the experimental side, the enormous data challenge of newly emerging experiments, such as the upgrade of the Large Hadron Collider. In this roadmap paper, led by CERN, DESY and IBM, we provide the status of high-energy physics quantum computations and give examples for theoretical and experimental target benchmark applications, which can be addressed in the near future. Having the IBM 100 100 challenge in mind, where possible, we also provide resource estimates for the examples given using error mitigated quantum computing. © 2023, CC BY-SA.
