electric and hybrid electric vehicles are attractive candidates for sustainable transportation due to its higher efficiency and low emission. the critical choice on the electric motors is its capability of motoring and regenerative braking characteristics. switched reluctance machines are viable candidate as with proper control and extended constant power range operation replacing the multi-gea...

‎an  oriented perfect path double cover (oppdc) of a‎ ‎graph $g$ is a collection of directed paths in the symmetric‎ ‎orientation $g_s$ of‎ ‎$g$ such that‎ ‎each arc‎ ‎of $g_s$ lies in exactly one of the paths and each‎ ‎vertex of $g$ appears just once as a beginning and just once as an‎ ‎end of a path‎. ‎maxov{'a} and ne{v{s}}et{v{r}}il (discrete‎ ‎math‎. ‎276 (2004) 287-294) conjectured that ...

this paper investigates axial compression process of multi-layered tubes with circular cross-section under the axial loading in the quasi-static condition using experimental method. some specimens are prepared in seven different groups, namely; empty carbon/epoxy composite tubes, solid carbon/epoxy composite rods, empty copper tubes, composite tubes with silicon sealant filler, concentrically s...

in many applications the quality of a process or product is best characterized and summarized by a functional relationship between a response variable and one or more explanatory variables. profile monitoring is used to understand and to check the stability of this relationship over time. therefore checking the capability of a profile seems essential. process capability indices have become very...

a multi objective honey bee mating optimization (hbmo) designed by online learning mechanism is proposed in this paper to optimize the double fuzzy-lead-lag (fll) stabilizer parameters in order to improve low-frequency oscillations in a multi machine power system. the proposed double fll stabilizer consists of a low pass filter and two fuzzy logic controllers whose parameters can be set by the ...

The constantly rising fraction of industrial services reveals the structural economic change that is changing the manufacturing industry landscape. Manufacturing firms have more and more problems to find the appropriate information technology (IT) solution for planning and execution as they are confronted with the strategic challenge of reducing operating costs while at the same time meeting ev...

The capability maturity model integration (CMMI) has become one of the most preferred approaches to software process improvement (SPI). However, the amount of discontinued or delayed CMMIdriven SPI projects is considerable. In this paper we investigate the culture embedded in the CMMI and compare it with the cultures within an implementing organization in Scandinavia by utilising the competing ...

As information technologies evolve and demands of enterprises on larger data and integrated info services keep growing, the market of cloud services (CS) attracts many more players nowadays. However, the quality of the services may vary due to different service capabilities and a service often requires integration with other services, CS providers need a standard way in implementing and improvi...

Background: Maturity models for IT service such as CMMI-SVC and MR-MPS-SV requires identification of critical business process and definition of relevant metrics to support decision making, but there is no clear direction or strict suggestion about which should be those processes and metrics. Aims: We aim to identify adequate metrics to be used by organizations deploying IT service maturity mod...

in the last 150 year, most destructive earthquakes of kopeh dagh occurred near quchan. these earthquakes caused large damages to quchan (tchalenko, 1975; ambraseys and melville, 1982). the kopeh dagh zone accommodates a motion, by a combination of slip-partitioning in the nw, thrust faulting in the se, and anticlockwise block rotation in the central kopeh dagh (hollingsworth et al. 2006, 2008)....
