An implementation of evolutionary heuristic algorithm, which is a specific modified variant of cultural algorithm, with simplified computational procedure is presented here for solving assignment problems. A cultural algorithm consists a population component almost identical to that of the genetic algorithm and, in addition, a knowledge component called the belief space. The major constraint of assignment problems that a single job can be assigned to only one resource and the resource or job that involves the largest and as well as the least cost are availed as the knowledge components to be used to build belief space. © Operational Research Society of India 2013.

One of the important goals in diesel engine research is the development of means to reduce the emissions of oxides of nitrogen (NOx) and soot particulates, and in this endeavour advanced techniques like split injection/multiple injection, exhaust gas recirculation (EGR) etc. are being developed. The principle of split injection is that when fuel is injected in two pulses it engenders a reduction in the peak combustion chamber temperature which ensures the reduction in NOx emission. In this study to achieve split injection in an economical manner, a double lobed cam has been designed incorporating the optimum split and dwell. Experimental study indicates that 50-50 split with 10 degree crank angle dwell is the optimum to achieve a viable reduction in NOx without any major penalty in soot and power. A 15% reduction in NOx and 10% reduction in soot was observed on incorporating these results. © School of Engineering, Taylor’s University.

A trans-Atlantic wave of puzzlement is rippling across Sweden for the second time in a week, after a prominent Fox News program featured a "Swedish defense and national security advisor" who's unknown to the country's military and foreign-affairs officials. Swedes, and some Americans, have been wondering about representations of the Nordic nation in the U.S. since President Donald Trump invoked "what's happening last night in Sweden" while alluding to past terror attacks in Europe during a rally Feb. 18. There hadn't been any major incident in Sweden the previous night. SEE ALSO: Sweden's embassy in the U.S. is looking forward to schooling Trump Then, Fox News commentator Bill O'Reilly convened an on-air face-off Thursday over Swedish immigration and crime between a Swedish newspaper reporter and a man identified on screen and verbally as a "Swedish defense and national security advisor," Nils Bildt. Bildt linked immigration to social problems in Sweden, lamented what he described as Swedish liberal close-mindedness about the downsides of welcoming newcomers and said: "We are unable in Sweden to socially integrate these people," arguing that politicians lacked a systematic plan to do so. But if viewers might have taken the "advisor" for a government insider, the Swedish Defense Ministry and Foreign Office told the newspaper Dagens Nyheter they knew nothing of him. Calls to Swedish officials Saturday weren't immediately returned. Bildt is a founding member of a corporate geopolitical strategy and security consulting business with offices in Washington, Brussels and Tokyo, according its website. His bio speaks to expertise on defense and national security issues, saying his experience includes serving as a naval officer, working for a Japanese official and writing books on issues ranging from investment and political climates to security issues in working in hostile environments. But security experts in Sweden said he wasn't a familiar figure in their ranks in that country. "He is in not in any way a known quantity in Sweden and has never been part of the Swedish debate," Swedish Defence University leadership professor Robert Egnell said by email to The Associated Press on Saturday. He and Bildt — also known then as Nils Tolling — were in a master's degree program in war studies together at King's College London in 2002-2003, and Bildt moved to Japan soon after, he said. Johan Wiktorin, a fellow at the Royal Swedish Academy of War Sciences, also tweeted that the guest was "not known in our circles as an expert. Not on National Security anyway." The executive producer of "The O'Reilly Factor" said Bildt was recommended by people the show's booker consulted while making numerous inquiries about potential guests. "After pre-interviewing him and reviewing his bio, we agreed that he would make a good guest for the topic that evening," executive producer David Tabacoff said in a statement. In any case, Twitter didn't take long to make a mockery of Fox News' mystery expert. The network said O'Reilly was expected to address the subject further on Monday's show. Bildt didn't respond Saturday to email inquiries; a person who answered the phone at his company agreed to relay one. He told Dagens Nyheter on Friday that he was a U.S.-based independent analyst, and Fox News had chosen its description of him.

"Sorry for any confusion caused, but needless to say I think that is not really the issue. The issue is Swedish refusal to discuss their social problems and issues," he added in a statement to the news website Mediaite, explaining his profession as being an independent political adviser. Trump's initial remark about "last night in Sweden" stirred a burst of social media mockery, while Trump explained on Twitter that he was referring to a Fox News piece on immigration and Sweden that he'd seen the night before. Trump and his supporters, though, saw vindication when a riot broke out Monday after police arrested a drug suspect in a predominantly immigrant suburb of Stockholm. Cars were set on fire and shops looted, but no one was injured. Trump took to Twitter again Monday to declare that large-scale immigration in Sweden was "NOT!" working out well, upsetting many Swedes. Associated Press writers Jan Olsen in Copenhagen and Mesfin Fedaku in New York contributed to this report.

This paper presents an analysis on a production shop floor layout of a Can manufacturing company and the application of a systematic layout planning (SLP) procedure as an approach to solve the production shop floor layout problem. The relationship between machines, operation activities and material flow are used to determine the optimal location of each machine. SLP technique has been employed to design the two alternative production shop floor layouts and compare the performance between new layout and present layout in terms of material flow distance, traveling time, and traveling cost. The existing production process was inefficient, showing bottlenecks. The alternative layouts were developed based on minimum distance traveled between each pair of machine. It improved the company existing layout by reduced total movement traveled in production for material handling. The measurements covered the actual sizes of the layout and machines, activities between machines, distance between machines, and material flow between machines in the company. The proposed procedure is illustrated to be a viable approach for solving production shop floor layout design problem through a real-world case study. From the proposed two alternative layouts which are more economical, distance of the production flow can be shortened from 389.7m to 311.2m or 360.6m. The traveling time can be reduced from 901sec. to 750sec. and traveling cost can be reduced from 3.17 Birr to 2.98 or 2.19 Birr per each travel resulting increase in productivity. © 2013 IEEE.

A computational study has been carried out to analyse the shock wave turbulent boundary layer interaction in a two-dimensional compression ramp flow for a free stream Mach number of 2·94. Ramp angles ranging from 8° to 24° are used to produce the full range of possible flow fields, including flows with minor separation, moderate separation, and significant amount of separation. The model has been analysed using 2D numerical simulations based on a commercially available Computational Fluid Dynamics (CFD) Code, Fluent, that employs k-ω Shear Stress Transport (SST) turbulence model. The computed data for surface pressure distribution indicated a good agreement with experiment. Numerical results obtained through the present series of computations indicate an increased extent of separated zone, and thus show increased upstream influence when compared to experiment. Total pressure loss has shown to increase downstream of separation location and increase when corner angle increases. Secondary separation has been observed for higher angles.

This paper investigates the dynamic properties and chaos control in a fractional order brushless DC (BLDC) motor. The fractional order model of the brushless DC motor has been derived from its integer order model. Then the qualitative properties of the fractional order BLDC motor are derived. Bifurcation analysis of the BLDC motor with the fractional order has been also discussed. Fractional order chaos control in the BLDC motor is achieved using sliding mode control, robust control and extended back-stepping control. © 2016 Springer-Verlag Berlin Heidelberg

This article describes a negative effect of size tolerance on the trigger characteristic. The trigger characteristic is the dependence of trigger force and trigger angle. An invalid trigger characteristic affects the accuracy of shooting and can be changed by not only proper choice of dimensions, but also the location of individual components. The paper shows an example of trigger mechanism that is designed as a Glock type mechanism. The solution for designers of small arms authors suggested the use of software MW. © 2012 Journal of Mechanical Engineering. All rights reserved.
