A rapidly exploring random tree optimization algorithm for space robotic manipulators guided by obstacle avoidance independent potential field

The crucial problem of obstacle avoidance path planning is to realize both reducing the operational cost and improving its efficiency. A rapidly exploring random tree optimization algorithm for space robotic manipulators guided by obstacle avoidance independent potential field is proposed in this article. Firstly, some responding layer factors related to operational cost are used as optimization objective to improve the operational reliability. On this basis, a potential field whose gradient is calculated off-line is established to guide expansion of rapidly exploring random tree. The potential field mainly considers indexes about manipulator itself, such as the minimum singular value of Jacobian matrix, manipulability, condition number, and joint limits of manipulator. Thus, it can stay the same for different obstacle avoidance path planning tasks. In addition, a K-nearest neighbor–based collision detection strategy is integrated for accelerating the algorithm. The strategy use the distance between manipulator and obstacles instead of the collision state of manipulator to estimate the distance between new sample configuration and obstacle. Finally, the proposed algorithm is verified by an 8-degree of freedom manipulator. The comparison between the proposed algorithm and a heuristic exploring–based rapidly exploring random tree indicates that the algorithm can improve the efficiency of path planning and shows better kinematic performance in the task of obstacle avoidance.
Notas Científicas Bovine herpesvirus type 1 in cumulus ‐ oocyte complexes collected from naturally infected cows

The objective of this work was to investigate the presence of bovine herpesvirus type 1 (BoHV‐1) in follicular fluid and in cumulus‐oocyte complexes (COC) recovered from naturally infected cows but with no clinical signs of the disease. Cows that were seropositive (n=38) or seronegative (n=8, control) to infectious bovine rhinotracheitis were selected after a serum neutralization test in microplates. The presence of the virus was investigated by PCR in COC and in follicular fluid. Viral DNA was not found in any of the samples. The obtained results suggest that serologically positive cows with no clinical signs of the disease offer negligible risk of transmitting BoHV‐1 by COC or follicular fluid.
A preordering method using head-restructured CFG parse tree for SMT

In previous researches, reordering input sentences to the expected word order of the target language before training a translation model improved the translation quality. The work of (Yamada & Knight, 2001) is considered as a forerunner in reordering syntactic parse trees. Basically, automatically generated syntactic information or human-made rules are utilized in the reordering process. As an example, the state-of-the-art reordering method for English-to-Japanese, Head-finalization (Isozaki et al., 2010) utilizes head-driven phrase structure grammar (HPSG) parse trees.
Leadership and the future of the profession

I do not pretend to be a student of leadership theory, rather these comments come from my experience as a CEO and the other leadership roles I have taken over the years. Also, these thoughts are shaped by my more recent role as an Executive Coach working with leaders and also by being a member of the Executive of the BPC. These musings aren’t aimed at analysing the dynamics of our organisations – there are many good thinkers who have elucidated these processes from a systems-psychodynamic perspective. Rather this piece focuses on the need for leadership and why we seem to be struggling first to find leaders and then when we do, we struggle to follow the leaders we have.
An interpromoter region enhAnces trAnscription of arg k gene , encoding the phAseolotoxin-resistAnt ornithine cArbAmoyltrAnsferAse in Pseudomonas syringae pv . phaseolicola

Pseudomonas syringae pv. phaseolicola, is the causal agent of halo blight on bean, a disease characterized by water soaked lesions surrounded by a chlorotic halo, which is produced by the action of phaseolotoxin, a nonhost-specific toxin optimally produced between 18°C to 20°C. To protect itself against phaseolotoxin, P. syringae pv. phaseolicola possesses a phaseolotoxin-resistant OCTase (ROCT) encoded by argK, which is expressed under conditions leading to the synthesis of phaseolotoxin. The promoter of argK is divergent to that of phtABC genes and both share an interpromoter region. The objective of the present study was to evaluate the role of the interpromoter region on argK transcription in P. syringae pv. phaseolicola. To this, deletions of the interpromoter region were made and argK expression was evaluated in an heterologous system. Also, the effect of multiple copies of the interpromoter region on phaseolotoxin production was determined. The obtained results showed that this region is necessary to enhance the transcription of argK. Additionally, this region in a multiple copies, interfered with the thermoregulation of phaseolotoxin at 28°C in strain P. syringae pv. phaseolicola NPS3121.
1 3 0 Ju l 2 00 6 Analysis of Stochastic Evolution

Many studies in Economics and other disciplines have been reporting distributions following power-law behavior (i.e distributions of incomes (Pareto’s law), city sizes (Zipf’s law), frequencies of words in long sequences of text etc.)[1, 6, 7]. This widespread observed regularity has been explained in many ways: generalized Lotka-Volterra (GLV) equations, self-organized criticality and highly optimized tolerance [2,3,4]. The evolution of the phenomena exhibiting power-law behavior is often considered to involve a varying, but size independent, proportional growth rate, which mathematically can be modeled by geometric Brownian motion (GBM) dXt = rtXtdt+αXtWt where Wt is white noise or the increment of a Wiener process. It is the primary purpose of this article to study both the upper tail and lower tail of the distribution following the geometric Brownian motion and to correlate this study with recent results showing the emergence of power-law behavior from heterogeneous interacting agents [5]. The result is the explanation for the appearance of similar properties across a wide range of applications.
Performance Analysis of Two Level and Multilevel inverter fed Induction Motor Drive

Frequency converters are used in wind turbines because they make it possible to apply the variable-speed concept. They also make it possible for wind farm to become active element in the power system. The traditional frequency converter is back-to-back connected two level converters, in which the output voltage has two possible values. However, the output voltage is smoother with a three-level converter, where output voltage has three possible values. This results in smaller harmonics, but on the other hand it has more components and is more complex to control. Multilevel inverter machinery has emerged recently as a very important alternative in the area of high power medium-voltage control and also for improving the total harmonic distortion by reducing the harmonics. Generally, the poor quality of voltage and current of a conventional inverter fed induction machine is obtained due to the presence of harmonics and hence there is a significant level of energy losses. The objective of this paper is to obtain a 3-level output, which is acquire by a three phase three level cascaded multilevel inverter (MLI) fed induction motor drive. This paper compares three phase two level inverter and three level cascaded inverter fed induction motor Drive. Keywords— Two level inverter, PWM Techniques, Total Harmonic Distortion, Cascaded three level Inverter, Induction motor.
Design and Analysis of an Electrically Controlled Permanent Magnet Excited Synchronous Machine

In this paper, a unique type of machine – namely, the Electrically Controlled Permanent Magnet Excited Synchronous Machine (ECPSM) possessing field weakening capability is proposed and tested. The key is to incorporate a simple fixed DC coil into a stator of the machine. Thus, the resulting new type of motor can offer effective flux control. The design method of the ECPSM machine is presented in detail. By combining the use of GOT-It-software and the Flux3D application for the optimization of a finite element model, the static and transient electromagnetic performance are investigated. Experimental results of the ECPSM are given to verify the validity of the proposed machine.
The pressure distribution characteristics of a typical bluff-section model

ABSTRACT: Typical bluff-section model pressure distributions are measured in the condition of fixed model as well as fluttering model with and without stabilizer in this paper. Firstly, surface pressure fluctuation characteristics of the bluff-section model during flutter are analyzed. Then, surface pressure distribution characteristics are analyzed based on proper orthogonal decomposition ( POD ). In the end, pressure distributions are compared between fixed model and fluttering model with and without stabilizer.
Diet composition of syntopically breeding falcon species

The red-footed falcon and Eurasian falcon represent two syntopical falcon species. While the Eurasian falcon is considered a common and numerous species in Slovakia, the red-footed falcon population has undergone a considerable decline during the past few decades. Nowadays it nests in a single locality in Slovakia, the Sys ovské polia Special Protection Area, which forms the northern and fragmented border of the species distribution area in Europe. By analysing prey remains from 9 nests (from 1998, 2001, 2013, 2014 and 2016), we identified 433 prey items belonging to 35 taxa and 9 orders. Every year, invertebrates made up the major part of the diet spectrum, in which Calosoma auropunctatum, Tettigonia viridissima, Zabrus tenebrioides, Anisoplia aegetum and Rhizotrogus sp. were the most frequent species of prey. Of the vertebrates, Microtus arvalis was the most hunted prey species. By supplementary analysis of 21 photos, we extended our knowledge on the diet by other 6 taxa. The peak of the M. arvalis population growth in 2014 did not manifest itself in the red-footed falcon diet composition. In 1998, 2014 and 2016 we also studied the diet of a syntopical species, the Eurasian kestrel. By analysing prey remains in 22 nests, we identified 1,151 prey items belonging to 37 taxa and 7 orders. In 1998 and 2014 vertebrates predominated, especially the common vole, however in 2016 invertebrates prevailed. This fact could be a reaction to the M. arvalis population peak in 2014 and its decline in 2016. These results suggest that this variability in the foraging behaviour of the Eurasian kestrel, an opportunistic predator, during the hunting of invertebrates increases the diet similarity and overlapping of the food niche of both studied falcon species.
Using ANSYS and SORCER Modeling Framework for the Optimization of the Design of a Flapping Wing Bionic Object

Growing modeling software capabilities together with available computational resources enable the modeling of more and more complex multi-physical problems. At the same time, the preparation of such simulation requires a collaboration of both engineers and software. Multidisciplinary Design Optimization (MDO) platforms are used to integrate simulation tools and expert knowledge that represents various engineering disciplines. The presented study demonstrates an effective use of a specialized CFD program and an MDO platform – the SORCER Modeling Framework (SMF) for the automation and optimization of the design of a flapping wing bionic object. The SMF realizes an optimization loop by using independent blocks prepared using ANSYS Workbench. An unsteady flow generated by the prescribed flapping wing trajectory is simulated. A number of geometrical and physical parameters is defined in the SMF model and then transferred to the slave blocks of the CFD program. An automated ANSYS workflow generates a geometry of computational domain, realizes it's proper meshing, initializes and performs the simulation, and finally passes the results to the SMF. The proposed system is an example of usage of the SMF that demonstrates the connection of specialized knowledge and a complex CFD simulation with simple and efficient control.
NUMERICAL CALCULATION OF CONSERVATION LAWS IN

The aim of this paper was the numerical computing of the first conservation law present in the interactions between solitons generated from numerical solutions of the Korteweg de Vries (KdV) equation. As follows from the theory of partial differential equations in which appears solitons, like some solutions of the KdV, many interesting behaviors come associated with them, in particular the conservation laws derived from it. Only the first three ones have direct interpretation or are associated with physical quantities, such as conservation of energy, momentum or mass density. The remaining are conservation laws in the strict sense of physics but do not have a clearly associated with magnitudes that usually appear in physical processes. The KdV equation constitutes one of the called “integrable systems” and in this way the conservations laws derived from it, have special interest for applications on the study of solitons’s propagation. These non-linear traveling waves that can be found from tsunamis in the oceans, transmission of information by transoceanic fiber optic communications, transmitted information through neural microtubules in living beings have a relevant technological and scientific interest. So the knowledge of conservation laws in the interaction between solitons becomes very interesting from both point of view technological and for the study of certain process in living beings. To obtain the explicit form of the conservation laws derived from the KdV equation, mainly due to the large number of terms that arise in the mathematical expression of them, there were developed a computational code implemented in a symbolic calculus platform that facilitated their algebraic handling. The conservation laws thus obtained were numerically evaluated during the computing integration of the KdV equation, based on an spectral type scheme. Their solutions represent the interaction of two solitons. Among the obtained results it can be pointed out that if the generation of solitons by solving the KdV equation has a high degree of approximation, the integrals of motion does not require highly sophisticated numerical algorithms to be satisfied and also make a numerical validation of the integration schemes of the nonlinear equation under study.

PREDICTION OF ENVIRONMENTAL FLOW CONDITION FROM RAINFALL USING RELATIONSHIP BETWEEN TENNANT METHOD AND STANDARDIZED PRECIPITATION INDEX

In the present study, an effort has been made to describe the environmental flow condition of a watershed using Standardized Precipitation Index (SPI), a drought index based on the precipitation. Mohegaon, Manot, Hridaynagar and Sher are the four watersheds of upper Narmada Basin have been taken for the analysis. The purpose of this study is to derive relationship between environmental flow condition and the corresponding estimates of Standardized Precipitation Index which is used as measure of drought conditions. It is expected that these relationship will be useful in determining environmental flow conditions in ungauged sub-basins using rainfall data only. The study revealed an excellent relationship between SPI and percentage of average annual flow as the value of coefficient of determination are greater than 0.75. The analysis indicates that for each of the four watersheds the percentage of average annual flow increases with the increase in the value of SPI. It can be concluded that the relationships presented in this paper will be useful for estimating the EF condition for ungauged watersheds.

Sparse robust portfolio optimization via NLP regularizations

We deal with investment problems where we minimize a risk measure under a condition on the sparsity of the portfolio. Various risk measures are considered including Value-at-Risk and Conditional Value-at-Risk under normal distribution of returns and their robust counterparts are derived under moment conditions, all leading to nonconvex objective functions. We propose four solution approaches: a mixed-integer formulation, a relaxation of an alternative mixed-integer reformulation and two NLP regularizations. In a numerical study, we compare their computational performance on a large number of simulated instances taken from the literature.
A Unified Theory of All the Fields in Elementary Particle Physics Derived Solely from the Zero-Point Energy in Quantized Spacetime

We propose a new theory beyond the standard model of elementary-particle physics. Employing the concept of a quantized spacetime, our theory demonstrates that the zero-point energy of the vacuum alone is sufficient to create all the fields, including gravity, the static electromagnetic field, and the weak and strong interactions. No serious undetermined parameters are assumed. Furthermore, the relations between the forces at the quantum-mechanics level is made clear. Using these relations, we quantize Einstein’s gravitational equation and explain the Dark Energy in our universe. Beginning with the zero-point energy of the vacuum, and after quantizing Newtonian gravity, we combine the energies of a static electromagnetic field and gravity in a quantum spacetime. Applying these results to the Einstein gravity equation, we substitute the energy density derived from the zero-point energy in addition to redefining differentials in a quantized spacetime. We thus derive the quantized Einstein gravitational equation without assuming the existence of macroscopic masses. This also explains the existence of the Dark Energy in the universe. For the weak interaction, by considering plane-wave electron and the zero-point energy, we obtain a wavefunction that represents a β collapse. In this process, from a different point of view than Weinberg-Salam theory, we derive the masses of the W and Z bosons and the neutrino, and we calculate the radius of the neutron. For the strong interaction, we previously reported an analytical theory for calculating the mass of a proton by considering a specific linear attractive potential obtained from the zero-point energy, which agrees well with the measurements. In the present study, we calculate the strong interaction between two nucleons, i.e., the mass of the pi-meson. The resulting calculated quantities agree with the measurements, which verifies our proposed theory.

The plantlets acclimatized and transferred to soil.
EFFECT OF DIFFERENT LEVELS OF INULIN AND XANTHAN ON SURVIVAL OF PROBIOTIC BACTERIA IN DOOGH TO PRODUCE A FUNCTIONAL DAIRY

In recent years, consumption of food products containing probiotic microorganisms has become more widespread due to its health benefits. The use of probiotic dairy products, especially probiotic Doogh has become very important in Iran, So that adding probiotic bacteria and the viability of them can contribute to improving the health of consumers. The aim of this study, was to evaluate the effects of Inulin (1%, 2% and 3%) and Xanthan (0.1%, 0.2% and 0.3%) as a prebiotic compared with control sample (without prebiotic) along with bacteria inoculation of lactobacillus acidophilus and Bifidobacterium lactis as starter (2%) to produce synbiotic Doogh and assessment of physicochemical characteristics and the viability of probiotic bacteria in the Doogh during storage. The results of the ANOVA on different treatments inoculated with 2% probiotic bacteria indicated that SNF, lactobacillus acidophilus and Bifidobacterium lactis bacteria count and sensory properties were significantly (P<0.05) different among the treatments. Moreover, maximum and minimum viability of Lactobacillus acidophilus on 21th day were related to Doogh containing 2% inulin and 0.3% Xanthan, respectively. Maximum and minimum viability of Bifidobacterium lactis also were related to Doogh containing 2% inulin and control, respectively.
