There are many publications of returned influence of the nonlinear consumer of electric energy on a power line. All articles concerns calculation of distortion degree by the higher harmonics of supply voltage curve. But it is important to know the degree of the total current distortion of individual consumers. The article proposes an analytical method for the determination of individual contributions to the overall distortion of the network current. You can use the method for calculating and measuring. © 2016 IEEE.

The method of origin-destination flows estimation based on Markov properties of a transportation network is considered. A formal description of a transportation graph is provided. A canonical form of the matrix of transition probabilities for the transportation graph is obtained. Maximum likelihood estimates of transition probabilities is provided. A method for estimating indirect transition probabilities using a fundamental matrix of the Markov chain is proposed. This method is able to be used for obtaining a transport origin-destination matrix. An example of a matrix calculation of some transportation graph is presented. Opportunities for a practical usage of the proposed method are provided. © 2016 IEEE.

An improved estimation method of electrochemical impedance equivalent circuits' parameters is proposed. The method allows to decrease estimation errors of an electrolyte resistance in up to 6.5 times, a double layer capacitance-up to 5.8 times, and a charge transfer resistance-up to twice. The accuracy of Warburg constant estimation remains unchanged. To obtain electrolyte resistance estimation, an approximation of total electrochemical impedance hodograph in upper frequency range by circle arcs is used. Taubin and modified by us Levenberg-Marquardt algorithms are applied [1]. An accuracy gain for charge transfer resistance estimation is reached due to more accurate estimations of interfering elements (electrolyte resistance and double layer capacitance) and following compensation of their influence. © 2016 IEEE.

In this article researches are conducted in the variants of robust criteria for selection the regression model with the use of LS-SVM method in the conditions of foul data use. For estimation of model parameters uses M-estimation method with the Huber loss function. For the settings of LS-SVM algorithm parameters is used the cross-validation criterion and its robust variants. © 2016 IEEE.

In work is conducted a comparative research of estimation accuracy of parameters of fuzzy regression models with various types of m-estimates, are considered several types of loss known functions. The purpose of this research is to obtain practical recommendations for using the considered of loss functions for constructing robust fuzzy regression. Were considered two options for clogging the data sample: With a symmetric clogging or asymmetric clogging. Samples observations range from small 25 to 300. Was analyzed the rate norm bias estimates decrease and the mean square error with increasing number of observations with various loss functions. Make are certain conclusions. © 2016 IEEE.

HALIFAX, NOVA SCOTIA--(Marketwired - Oct. 27, 2016) - CUPE sends a message of solidarity and support to teachers across Nova Scotia today, in their efforts to gain a fair collective agreement with the McNeil government. "On behalf of the 19,000 members of CUPE Nova Scotia, including 4,000 school board support staff, I want to express our full support for the membership of the Nova Scotia Teachers Union," says CUPE Nova Scotia President Nan McFadgen. "Premier McNeil is creating havoc in the public service and he clearly does not understand the difficulties faced by workers. He doesn't see the financial pressures and emotional strain placed on workers and their families when they are not able to negotiate their own wages, benefits and working conditions," says McFadgen. "Teachers deserve recognition for their hard work over the years to help improve the education system in Nova Scotia. It is time for the Province to meet with teachers to have a round of bargaining in which they are able to bargain their wages, and to work in an environment where their expertise is taken into consideration when decisions are made for the betterment of students and schools." "Rather than impose contract terms, he should allow the collective bargaining process to function as it was intended," states McFadgen. "Teachers have sent a clear message, rejecting McNeil's strong-arm approach and CUPE fully supports NSTU members in their struggle, and all public employees, until such a time as the Liberal government shows the workforce the respect it deserves."

HALIFAX, NOVA SCOTIA--(Marketwired - Feb. 15, 2017) - "CUPE strongly opposes the McNeil Government's move to impose a contract on the members of the Nova Scotia Teachers Union (NSTU)," says Nan McFadgen, president of CUPE Nova Scotia. "We feel this piece of anti-worker legislation is undemocratic and will only serve to hurt all public service workers in Nova Scotia, who have the constitutional right to negotiate and vote on their collective agreement." On February 11, Premier Stephen McNeil announced he would impose a contract on the Nova Scotia Teachers Union (NSTU) and began imposing the agreement on teachers the evening of Tuesday, February 13, 2017. Debate on the legislation, entitled the Teachers' Professional Agreement and Classroom Improvement Act (Bill 75), is taking place this week and will likely be voted on next week. "CUPE members are frustrated by the Premier's refusal to recognize the value of the jobs education workers do including CUPE members who are educational assistants, school secretaries, custodians, bus drivers, early childhood educators and much more." says Grant Dart, CUPE school board coordinator. "How can the Minister of Education say, with a straight face, that she hopes NSTU members feel they have their fingerprints on this contract? How can any union have faith in this government, when we go through good faith negotiations, only to have a contract imposed on them," says McFadgen. "Collective bargaining works. When both sides agree to meet in good faith and with respect for the process, it works for everyone," says McFadgen. "It safeguards workers' rights and stabilizes the public services that we all depend on. It also sets new workplace standards such as pay equity and health and safety." "Introducing Bill 148, and now Bill 75, was a huge mistake, and imposing a contract on teachers will create chaos in the education system," says McFadgen. "It's unfortunate that we live in a province where education workers are also forced to fight to improve the quality of education our children receive. We applaud NSTU members for their courage and determination." "We will not back down. The livelihoods and security of 75,000 public service workers, their families and their communities depend on reaching fairly negotiated contracts," states McFadgen. "Underfunding classrooms and attacking workers' rights are issues we believe will be reflected in voting polls in the next provincial election."
