the application of distributed generation systems is increasing day by day. Installing DG units is an appropriate option for power-quality improvement, loss reduction, and improved reliability. In this study, the endeavor is to determine an economic objective function for the expansion of DGs. the suggested model gives the owner a path towards the economic vision discussed here. In recent literature, the study of expansion regulations and economic and technical parameters related to DGs have not been much worthy of consideration. In this study, the objective function aims at the placement and capacity determining of DGs, and the Genetic Algorithm is used to optimize it economically.

Pairwise rank aggregation (PRA) aims at learning a ranking from pairwise comparisons between objects that specify their relative ordering. the present study proposes the use of rank difference information for PRA, which characterizes the extent winners in paired comparisons beat their opponents. While such information can be effortlessly recognized by annotators, to our knowledge, it has not been utilized for PRA before. the challenge is three-fold: how to solicit such information, how to utilize it in rank aggregation, and how to overcome the noise from heterogeneous annotators. this study proposes a new query for soliciting information about rank difference that imposes limited cognitive burden on annotators. As prior methods for PRA abounds, it is of interest to empower them with information on rank difference. To this end, this study proposes a conservative learning objective that can be combined seamlessly with many existing PRA algorithms. the third contribution is a new method for PRA called mixture of exponentials (MoE). Annotators from a heterogeneous population might have diverse views concerning rank difference. For example, an annotator might be good at recognizing rank difference only for a subset of items but not the rest. this means that information about rank difference is likely to be perturbed. Unfortunately, such an object-dependent error pattern cannot be modeled with existing approaches. MoE assumes that each annotator uses a mixture of ranking functions in generating answers, and the mixture components can capture object-related patterns in data. the present study evaluates the proposals with extensive experiments on both real and synthetic datasets. the results confirm the efficacy of the proposals and shed light on their practical usage.

the goal of this paper study is to schedule the power generation units to minimize fuel consump-tion cost based on a model that solves unit commitment problems. this can be done by utilizing forward dynamic programming method to determine the most economic scheduling of generating units. the model is applied to power station,which consists of four generating units. the obtained results show that the applications of forward dynamic programming method offer substantial re-duction in fuel consumption cost. the fuel consumption cost has been reduced from $ 116,326 to $ 102,181 within a 24-hour period. this means saving about 12.16% of fuel consumption cost. the study emphasizes the importance of applying modeling schedule programs to the operation of power generation units. Consequently,the less consumption of fuel is,the less losses of power and pollution will be.

Information systems are an integral part of every organization's critical resource and are an important responsibility of all organizations in this digital world to defend them from attacks. Misuse of critical systems of data raises serious difficulties to organizations which involve loss of productivity, profits, company loss, credibility loss and often, legal issues. this paper develops a framework to analyze the optimal selection of vulnerabilities having maximum severity and can be resolved in minimum time. In this study, an integrated framework involving Analytical Hierarchy process (AHP) and Entropy method is used to calculate the subjective and objective weights of software vulnerabilities. Severity of vulnerabilities is then computed by taking into consideration the combined weights calculated from AHP and Entropy method. To select the most critical vulnerability, a bi-objective programming problem is used with the objective of weight maximization and time minimization. the weighted goal programming approach is used to achieve a compromise between conflicting objectives and to achieve a satisfactory solution to the bi-objective problem. the findings are tested in the Delhi-National Capital Region by a software firm.

Bandwidth allocation and management is of paramount importance for telcos mainly in packet transport networks where bandwidth needs an even more tricky control than in the previous circuit-based SDH networks. In these new transport networks, as is the case of MPLS-TP or Carrier Ethernet networks, it is very important to balance the traffic load distribution in order to avoid localized overloads when some parts of the networks still have available bandwidth. the load balance in the network can improve the fulfillment of the service level agreements and the network performance, namely with respect to the amount of carried traffic. In point-to-point (p2p) virtual connections it is well known that the shortest paths obtained through the hop count metric can lead to an inefficient load distribution. In order to better distribute the traffic over the network other metrics that can be used in shortest paths algorithms have been proposed in the literature. In this paper we present a bicriteria approach in which the first objective has the purpose of better distribute the traffic in the network and the second objective function intends to minimize the amount of network resources involved in each virtual connection. this is a general approach that can be applied to different kind of virtual connections such as point to multipoint (p2m) or multipoint to multipoint (m2m). this paper is focused on the algorithms and the methods involved in the calculation and path selection for p2p connections and also presents a network performance study of the addressed methods, considering realistic transport networks.

the model predictive control (MPC) method has become more popular and widely used to control power converters due to its fast dynamic response and easy implementation. With the MPC method, it is simple to achieve multiple control objectives and handle the system constraints and nonlinearities by using a cost function. MPC can also be employed on the modular multilevel converters (MMCs) to achieve the control of output currents, circulating currents and DC-link voltage/ current. However, the biggest obstacle to applying MPC on the MMC is the huge calculation. To achieve the optimal switching state, MPC needs to evaluate all the possible switching states. As the number of submodules (SMs) increases, the number of the switching states drastically increases, which puts a huge computational burden on the processor. To solve this problem, the MPC with a box-constrained quadratic programming solver has been proposed. In this method, a quadratic problem (QP) has been solved firstly. Based on this solution, the possible switching combinations have been determined. Instead of evaluating all the possible switching states, only a very small number of switching combinations needs to be evaluated. Besides, by using this method, the computational burden does not increase as the number of SMs increases.
