For the past five years the Quantum Shorts initiative from the Center for Quantum Technologies at the National University of Singapore has inspired artists and writers from around the world to try their hand at a unique kind of scientific storytelling. The contest alternates each year between calls for films or short stories that explore the ramifications of quantum mechanics. The key requirement? Each entry must take no more than five minutes to watch or read. For 2016 the contest focused on film and drew more than 200 entries, with 10 finalists selected. Now, in partnership with Scientific American and Nature (as well as with several scientific institutions), Quantum Shorts 2016 has revealed this year’s first- and second-place winners as selected by a six-member panel of expert judges as well as a “people’s choice” winner selected via public online polling. The overall winner is Novae, filmmaker Thomas Vanz’s breathtakingly beautiful visualization of a giant star’s explosive death by supernova and subsequent transformation into a black hole. Like a latter-day William Blake—the English poet and painter who famously mused about seeing “a world in a grain of sand” and “a heaven in a wild flower”—Vanz envisioned a supernova in drops of colored ink. Working for months in his garage in Paris, he filmed inks billowing through a water-filled fish tank, later using computer software to stitch and process the raw footage into his dramatic vision of stellar death. His behind-the-scenes shorts detailing the making of Novae are at least as entertaining as the final film itself. A supernova can form a black hole by compressing a star’s core to an infinitesimally minuscule size, creating a gravitational field so intense that it devours light itself. The compressed core of a black hole—a “singularity,” in the parlance of physics—is thus hidden behind a black, lightless “event horizon,” the boundary beyond which anything falling in cannot come back out. Black holes represent a mysterious union between gravity, which dictates the overall structure of the universe, and quantum mechanics, which describes the cosmos at subatomic scales. Probing the properties of these strange macroscale quantum objects is likely to be our best path forward to a deeper understanding of the nature of reality. The runner-up, The Guardian, is also the people’s choice winner. The film uses a love triangle between three people to explore the counterintuitive nature of the quantum world, in which an entity can exist either as a particle or as a wave—or, really, as both at the same time, in a hazy cloud of probability. It is the brainchild of Chetan  Kotabage, an assistant professor of physics at KLS Gogte Institute of Technology in Karnataka, India. “I love that it is looking at quantum physics through a cultural lens,” says Eliene Augenbraun, Scientific American’s video producer and multimedia managing editor for Nature Research Group, who also served as a contest judge and chose The Guardian as her favorite. Other entries that earned honorable mentions from the judges include Approaching Reality, Together—Parallel Universe and Bolero. Charlotte Stoddart, Nature’s chief multimedia editor and contest judge, says she was “really impressed by the quality of the filmmaking and the ideas.” You can watch all the finalists here. The next call for Quantum Shorts entries will occur later this year. Continuing its annual alternation between cinema and prose, 2017’s contest will be for short stories. Announcements will be available via the Quantum Shorts Twitter account and Facebook page.

Wireless Mesh Networks (WMNs) are providing a mesh which maintains favourable bandwidth of internet to a substantial region and is replacing wired networks. Scheduling has become an important challenge in WMN that improves performance of the system. Scheduling schedules the resources to serve different nodes in the network. We review the centralized scheduling with interference based assignment algorithm. Interference based scheduling algorithm removes secondary interference which in turn reduces the length of scheduling. Analysis of using different algorithms is proposed that are meant to identify a collection of links to transmit at the same time from links that are available and assigning appropriate channels to them. © 2016 IEEE.

A baler, most often called a fodder baler is a piece of farm machinery used to compress a cut and raked crop (such as hay, cotton, flax straw, salt marsh hay, or silage) into compact bales that are easy to handle, transport, and store. Several different types of balers are commonly used, each producing a different type of bale - rectangular or cylindrical, of various sizes. The hydraulic fodder baler is a hydraulic press to manufacture compacted fodder bale for milch cattle. The bale provides total mixed ration for milch cattle to ensure healthy cattle, good milk yield and good economics. The fodder consists of Paddy, Wheat straw, Jowar cut to a length of 30 to 45mm. These dry stalks are mixed with molasses, rice Stover, cotton seed, maize etc. All these are mixed together in a rotary mixer. The above fodder mixture passes through a series of conveyors is fed to a vibrator and through the vibrator to the weighing bin. In the weighing bin it is weighed to set a value in kilograms. The weighing bin contents are unloaded to the main pressing chamber of the hydraulic fodder baler. © IEOM Society International.

Multidimensional optimization is critically important in engineering, economics and other disciplines. There are several deterministic approaches to optimization, each of which has its own pros and cons. Swarm intelligence-based optimization algorithms have been gained popularity for their effectiveness and resource efficiency. Two such popular algorithms, namely artificial bee colony (ABC) and particle swarm optimization (PSO) have been investigated in this paper. These algorithms have been implemented to minimize a few unimodal and multimodal benchmark functions. Results have been analyzed and the comparative analysis has been performed in terms of quality of solutions and computing time. Matlab simulation results show that the ABC algorithm delivers more accurate optimization than PSO does; but it suffers from delayed convergence. On the other hand, PSO is faster; but its accuracy is relatively inferior. © 2016 IEEE.

This work deals with optimization of axially magnetized stack structured permanent magnet (PM) thrust bearing using generalized three-dimensional (3D) mathematical model having "n" number of ring pairs. The stack structured PM thrust bearing is optimized for the maximum axial force and stiffness in a given cylindrical volume. MATLAB codes are written to solve the developed equations for optimization of geometrical parameters (axial offset, number of ring pairs, air gap, and inner radius of inner and outer rings). Further, the results of proposed optimization method are validated using finite element analysis (FEA) and further, generalized by establishing the relationship between optimal design variables and air gap pertaining to cylindrical volume constraint of bearing's outer diameter. Effectiveness of the proposed method is demonstrated by optimizing PM thrust bearing in a given cylindrical volume. Mathematical model with optimized geometrical parameters dealt in the present work helps the designer in developing PM thrust bearings effectively and efficiently for variety of applications. © 2017 by ASME.

Energy used to be produced mostly from fossil fuels until the near past, and the use of these fuels has created many environmental problems. For this reason, renewable energy resources have become important for energy production. Worldwide, about 86.4% of energy is produced by fossil fuels. Renewable energy has become an important agenda of India's energy planning process especially since climate change has taken centre stage in the domestic and international policy arena. To demonstrate its commitment to renewable energy, the government has set aggressive targets for renewables and several incentives and policy initiatives at the central and state levels have been put in place both for grid connected and off-grid renewable energy. An increasing tendency to use renewable energy resources in the world has revealed a need to study the current position of wind energy also and particularly the policies to increase the usage of wind energy. Wind energy provides a cost-effective and scalable alternative to conventional energies. The focus of this paper is on evaluating the effectiveness of policies with respect to deployment of renewable energy sources and in particular wind energy in India. © 2017 Inderscience Enterprises Ltd.

Power dissipation is a bottleneck in the design of low power electronic devices that, operate at high frequencies. Hence, the clock signal is a major source of power dissipation. The technique clock gating at the architecture level can be implemented to reduce the dynamic and clock power. In this paper, the authors aim at implementing, analyzing and comparing the various resource power using clock gating techniques to a 16-bit ALU on a 45nm SPARTANO FPGA board. The two clocking gates proposed and used in the design are namely: DEMUX and AND gate, which provide clock input to only one functional module that is either arithmetic or logical block, while the other is put OFF. The complete design is simulated using QuestaSim, synthesized using Precision tool and the power analysis is performed using Xpower analyzer of ISE13.2. The results obtained demonstrate that the clock, signal and the logic power for the two techniques is nearly same. While the IO and dynamic power using AND clocking gate has the power reduction of 50% and 45% respectively. Thus, the AND clock gating technique can be used in the design to optimize power and area. © 2014 IEEE.

The need to design and develop high performance and high speed VLSI systems such as NOCs in networking or SOCs in communication and computing has shifted the focus from traditional performance parameters towards the analysis of power consumption. In such devices managing the power among the domains of a system is of real concern. Hence, the low power design techniques namely: clock gating, power gating, dynamic voltage scaling and frequency scaling are of most important. In this paper the clock gating technique is applied to a 16-bit ALU. In the this work the ALU is divided into two functional units namely: Arithmetic unit and Logical Unit. The demultiplexer is used as a selector of the functional unit for which the clock is applied. The design is simulated using QuestaSim power aware simulator, implemented and synthesized using Precision synthesis tool on a Spartan 6 FPGA. Power analysis is carried out using Xilinx XPower analyzer. The design is tested for a wide band of frequencies from 1MHz to 5000MHz. The Clock and dynamic power reduction is observed for lower frequencies but for high frequency the target device has the limitation. The clock gating technique when applied to the design it is observed that the clock power is reduced by an average of 70% for lower frequencies and an average of 30% for higher frequencies. This reduction is at the cost increase in area by 2%. © 2014 IEEE.

Power dissipation is a bottleneck in the design of high speed synchronous systems operating at high frequency. Thus, clock signals have been a great source of power dissipation because of high frequency and heavy packet traffic in the network routers. Clock signals do not carry any information used for computation and only used for synchronization, but, the power dissipated is significant. In a Network Processor (NP) consisting of more than one processing elements (PE), not all are functioning at the same time, but connected to the clock signal dissipate power. Hence, the clock gating (CG) technique can to applied to these PEs. In this paper as a initial step to the design of such PEs the CG is applied to a 16-bit ALU. The design is simulated using QuestaSim power aware simulator, implemented and synthesized using Precision synthesis tool on a 45nm Spartan 6 FPGA. Power analysis is carried out using Xilinx XPower analyzer. Reduction in Clock and dynamic power is observed for lower frequencies but for high frequency the target device has the limitation. The design is optimized for power and area. © 2014 IEEE.

This work deals with generalized three-dimensional (3D) mathematical model to estimate the force and stiffness in axially, radially, and perpendicularly polarized passive magnetic bearings with "n" number of permanent magnet (PM) ring pairs. Coulombian model and vector approach are used to derive generalized equations for force and stiffness. Bearing characteristics (in three possible standard configurations) of permanent magnet bearings (PMBs) are evaluated using matlab codes. Further, results of the model are validated with finite element analysis (FEA) results for five ring pairs. Developed matlab codes are further utilized to determine only the axial force and axial stiffness in three stacked PMB configurations by varying the number of rings. Finally, the correlation between the bearing characteristics (PMB with only one and multiple ring pairs) is proposed and discussed in detail. The proposed mathematical model might be useful for the selection of suitable configuration of PMB as well as its optimization for geometrical parameters for high-speed applications. © Copyright 2016 by ASME.
