  1. Geographic Concentration of Business Services Firms: A Poisson Sorting Model

    Koster, Hans,; van Ommeren, Jos N.; Rietveld, Piet


    This paper estimates a heterogeneous sorting model for firms, employing a semiparametric Poisson approach. We show that there is an equivalence relation between a locally weighted Logit and Poisson model. We apply our model to estimate firm-specific preferences of business services firms for location attributes such as diversity of economic activities and specialisation of business services. We correct for endogeneity of our specialisation measure by means of a control function approach, usin...

  3. Sorting out the mess. A Review of Definitions of Ethical Issues in Business

    Egels, Niklas


    Hundreds of concepts have been proposed for describing how ethical issues in business should be defined. In this paper, I review how the six most commonly used concepts have been defined. This is a contribution to the international business ethics research, since hardly any academic work has reviewed more than one or two concepts simultaneously. The results from the review show that differences as well as similarities exist between the concepts in terms of context, content and perspectives. I...

  4. Sorting Out Sorts

    Jonathan B. Berk


    In this paper we analyze the theoretical implications of sorting data into groups and then running asset pricing tests within each group. We show that the way this procedure is implemented introduces a severe bias in favor of rejecting the model under consideration. By simply picking enough groups to sort into even the true asset pricing model can be shown to have no explanatory power within each group.

  5. Business Models for Solar Powered Charging Stations to Develop Infrastructure for Electric Vehicles

    Jessica Robinson


    Full Text Available Electric power must become less dependent on fossil fuels and transportation must become more electric to decrease carbon emissions and mitigate climate change. Increasing availability and accessibility of charging stations is predicted to increase purchases of electric vehicles. In order to address the current inadequate charging infrastructure for electric vehicles, major entities must adopt business models for solar powered charging stations (SPCS. These SPCS should be located in parking lots to produce electricity for the grid and provide an integrated infrastructure for charging electric vehicles. Due to the lack of information related to SPCS business models, this manuscript designs several models for major entities including industry, the federal and state government, utilities, universities, and public parking. A literature review of the available relevant business models and case studies of constructed charging stations was completed to support the proposals. In addition, a survey of a university’s students, staff, and faculty was conducted to provide consumer research on people’s opinion of SPCS construction and preference of business model aspects. Results showed that 69% of respondents would be more willing to invest in an electric vehicle if there was sufficient charging station infrastructure at the university. Among many recommendations, the business models suggest installing level 1 charging for the majority of entities, and to match entities’ current pricing structures for station use. The manuscript discusses the impacts of fossil fuel use, and the benefits of electric car and SPCS use, accommodates for the present gap in available literature on SPCS business models, and provides current consumer data for SPCS and the models proposed.

  8. Private financing and operation of a space station: Investment requirements, risk, government support and other primary business management considerations

    Simon, M.


    Private investment in a manned space station is considered as an alternative to complete government sponsorship of such a program. The implications of manned space operations are discussed from a business perspective. The most significant problems and risks which would be faced by a private company involved in a space station enterprise are outlined and possible government roles in helping to overcome these difficulties suggested. Economic factors such as inflation and the rate of interest are of primary concern, but less obvious conditions such as antitrust and appropriate regulatory laws, government appropriations for space activities, and national security are also considered.

  9. Alternative business models for establishing fast-charging stations - Part 2; Alternative forretningsmodeller for etablering av hurtigladestasjoner - Del 2



    This section of the report describes and evaluates potential business models for fast-charging stations. Business models are developed on the basis of market development for electric vehicles and electric vehicle usage patterns analyzed in Part 1 of the project. This report describes a series of models in both the early and maturity stage, where we have distinguished between different user segments and payment models. With the estimated trends in the car fleet and charger use, the prerequisites for profitable quick charging in the downtown area are good, while, due to high construction contribution, you must have a relatively high proportion of subscriptions and a high charge rate to obtain adequate finances in the corridor points.(auth)

    高庆狮; 胡玥; 刘志勇


    A k-bitonic sort which generalizes the bitonic sort is proposed. The theorem of the bitonic sort, which merges two monotonic sequences into one order sequence, is extended into the theorem of k-bitonic sort. The k-bitonic sort merges K (=2k or 2k-1) monotonic sequences into one order sequence in steps, where k=[K/2] is an integer and k≥1. The k-bitonic sort is the Batcher’s bitonic sort when k=1.

  8. Energy efficient data sorting using standard sorting algorithms

    Bunse, Christian


    Protecting the environment by saving energy and thus reducing carbon dioxide emissions is one of todays hottest and most challenging topics. Although the perspective for reducing energy consumption, from ecological and business perspectives is clear, from a technological point of view, the realization especially for mobile systems still falls behind expectations. Novel strategies that allow (software) systems to dynamically adapt themselves at runtime can be effectively used to reduce energy consumption. This paper presents a case study that examines the impact of using an energy management component that dynamically selects and applies the "optimal" sorting algorithm, from an energy perspective, during multi-party mobile communication. Interestingly, the results indicate that algorithmic performance is not key and that dynamically switching algorithms at runtime does have a significant impact on energy consumption. © Springer-Verlag Berlin Heidelberg 2011.

    Laëtitia Pedroso


    The selective or ecological sorting of waste is already second nature to many of us and concerns us all. As the GS Department's new awareness-raising campaign reminds us, everything we do to sort waste contributes to preserving the environment.    Placemats printed on recycled paper using vegetable-based ink will soon be distributed in Restaurant No.1.   Environmental protection is never far from the headlines, and CERN has a responsibility to ensure that the 3000 tonnes and more of waste it produces every year are correctly and selectively sorted. Materials can be given a second life through recycling and re-use, thereby avoiding pollution from landfill sites and incineration plants and saving on processing costs. The GS Department is launching a new poster campaign designed to raise awareness of the importance of waste sorting and recycling. "After conducting a survey to find out whether members of the personnel were prepared to make an effort to sort a...

  10. Microfluidic sorting of microtissues.

    Buschke, D G; Resto, P; Schumacher, N; Cox, B; Tallavajhula, A; Vivekanandan, A; Eliceiri, K W; Williams, J C; Ogle, B M


    Increasingly, invitro culture of adherent cell types utilizes three-dimensional (3D) scaffolds or aggregate culture strategies to mimic tissue-like, microenvironmental conditions. In parallel, new flow cytometry-based technologies are emerging to accurately analyze the composition and function of these microtissues (i.e., large particles) in a non-invasive and high-throughput way. Lacking, however, is an accessible platform that can be used to effectively sort or purify large particles based on analysis parameters. Here we describe a microfluidic-based, electromechanical approach to sort large particles. Specifically, sheath-less asymmetric curving channels were employed to separate and hydrodynamically focus particles to be analyzed and subsequently sorted. This design was developed and characterized based on wall shear stress, tortuosity of the flow path, vorticity of the fluid in the channel, sorting efficiency and enrichment ratio. The large particle sorting device was capable of purifying fluorescently labelled embryoid bodies (EBs) from unlabelled EBs with an efficiency of 87.3% ± 13.5%, and enrichment ratio of 12.2 ± 8.4 (n = 8), while preserving cell viability, differentiation potential, and long-term function.

  13. Sorting quantum systems efficiently

    Ionicioiu, Radu


    Measuring the state of a quantum system is a fundamental process in quantum mechanics and plays an essential role in quantum information and quantum technologies. One method to measure a quantum observable is to sort the system in different spatial modes according to the measured value, followed by single-particle detectors on each mode. Examples of quantum sorters are polarizing beam-splitters (PBS) – which direct photons according to their polarization – and Stern-Gerlach devices. Here we propose a general scheme to sort a quantum system according to the value of any d-dimensional degree of freedom, such as spin, orbital angular momentum (OAM), wavelength etc. Our scheme is universal, works at the single-particle level and has a theoretical efficiency of 100%. As an application we design an efficient OAM sorter consisting of a single multi-path interferometer which is suitable for a photonic chip implementation. PMID:27142705

  14. Gold ore sorting

    Apparatus for sorting lumps of gold-bearing ore according to their gold content is described. It includes means for irradiating the lumps of ore with neutrons, e.g. a neutron tube adapted to produce at least 1010 neutrons per second with an energy of less than 4.5 MeV. The resulting intensity of 297 keV gamma rays arising from the nuclear reaction 197Au(n,n'#betta#) 197Au is measured. The measured gamma ray intensity from a given lump of ore is used to sort that lump of ore from other lumps. The apparatus includes various cylinders and a vibrator for presenting the lumps of ore to the neutrons in a geometrical configuration such as to enable the lumps to be irradiated uniformly.

  15. Lipoprotein sorting in bacteria.

    Okuda, Suguru; Tokuda, Hajime


    Bacterial lipoproteins are synthesized as precursors in the cytoplasm and processed into mature forms on the cytoplasmic membrane. A lipid moiety attached to the N terminus anchors these proteins to the membrane surface. Many bacteria are predicted to express more than 100 lipoproteins, which play diverse functions on the cell surface. The Lol system, composed of five proteins, catalyzes the localization of Escherichia coli lipoproteins to the outer membrane. Some lipoproteins play vital roles in the sorting of other lipoproteins, lipopolysaccharides, and β-barrel proteins to the outer membrane. On the basis of results from biochemical, genetic, and structural studies, we discuss the biogenesis of lipoproteins in bacteria, their importance in cellular functions, and the molecular mechanisms underlying efficient sorting of hydrophobic lipoproteins to the outer membrane through the hydrophilic periplasm.

  18. Event shape sorting

    Kopečná, Renata; Tomášik, Boris


    We propose a novel method for sorting events of multiparticle production according to the azimuthal anisotropy of their momentum distribution. Although the method is quite general, we advocate its use in analysis of ultra-relativistic heavy-ion collisions where a large number of hadrons is produced. The advantage of our method is that it can automatically sort out samples of events with histograms that indicate similar distributions of hadrons. It takes into account the whole measured histograms with all orders of anisotropy instead of a specific observable ( e.g., v_2 , v_3 , q_2 . It can be used for more exclusive experimental studies of flow anisotropies which are then more easily compared to theoretical calculations. It may also be useful in the construction of mixed-events background for correlation studies as it allows to select events with similar momentum distribution.

  3. Pair Wise Sorting: A New Way of Sorting

    Md. Jahangir Alam


    Full Text Available This paper presents a technique for sorting numerical data in an efficient way. The numbers of comparisons i.e. the running time of this technique is dependent on distribution or diversity of the value of data items as like as other efficient algorithms. When the total number of data is even, this method groups that data into a collection of pairs and therefore establishes the sorting constraints on each of the pairs. The control is traversed through the list of elements by changing the position of each pair which is the major principle of this technique. On the other hand, when the total number of elements is odd, this method sorts all elements except the last one in the same was as mentioned earlier and the last element is sorted using the general Insertion Sort. This algorithm is therefore a hybrid sorting method that sorts elementary numeric data in a faster and efficient manner.

  4. Fluorescence activated cell sorting.

    Bonner, W. A.; Hulett, H. R.; Sweet, R. G.; Herzenberg, L. A.


    An instrument has been developed for sorting biological cells. The cells are rendered differentially fluorescent and incorporated into a small liquid stream illuminated by a laser beam. The cells pass sequentially through the beam, and fluorescent light from the cells gives rise to electrical signals. The stream is broken into a series of uniform size drops downstream of the laser. The cell signals are used to give appropriate electrostatic charges to drops containing the cells. The drops then pass between two charged plates and are deflected to appropriate containers. The system has proved capable of providing fractions containing large numbers of viable cells highly enriched in a particular functional type.

  5. Selective sorting of waste


    Not much effort needed, just willpower In order to keep the cost of disposing of waste materials as low as possible, CERN provides two types of recipient at the entrance to each building: a green plastic one for paper/cardboard and a metal one for general refuse. For some time now we have noticed, to our great regret, a growing negligence as far as selective sorting is concerned, with, for example, the green recipients being filled with a mixture of cardboard boxes full of polystyrene or protective wrappers, plastic bottles, empty yogurts pots, etc. …We have been able to ascertain, after careful checking, that this haphazard mixing of waste cannot be attributed to the cleaning staff but rather to members of the personnel who unscrupulously throw away their rubbish in a completely random manner. Non-sorted waste entails heavy costs for CERN. For information, once a non-compliant item is found in a green recipient, the entire contents are sent off for incineration rather than recycling… We are all concerned...

    Roos, Charles E.; Sommer, Edward J.; Parrish, Robert H.; Russell, James R.


    A method and apparatus are disclosed for classifying materials utilizing a computerized touch sensitive screen or other computerized pointing device for operator identification and electronic marking of spatial coordinates of materials to be extracted. An operator positioned at a computerized touch sensitive screen views electronic images of the mixture of materials to be sorted as they are conveyed past a sensor array which transmits sequences of images of the mixture either directly or through a computer to the touch sensitive display screen. The operator manually "touches" objects displayed on the screen to be extracted from the mixture thereby registering the spatial coordinates of the objects within the computer. The computer then tracks the registered objects as they are conveyed and directs automated devices including mechanical means such as air jets, robotic arms, or other mechanical diverters to extract the registered objects.

  10. On Approximability of Block Sorting

    Narayanaswamy, N S


    Block Sorting is a well studied problem, motivated by its applications in Optical Character Recognition (OCR), and Computational Biology. Block Sorting has been shown to be NP-Hard, and two separate polynomial time 2-approximation algorithms have been designed for the problem. But questions like whether a better approximation algorithm can be designed, and whether the problem is APX-Hard have been open for quite a while now. In this work we answer the latter question by proving Block Sorting to be Max-SNP-Hard (APX-Hard). The APX-Hardness result is based on a linear reduction of Max-3SAT to Block Sorting. We also provide a new lower bound for the problem via a new parametrized problem k-Block Merging.


    Evans, J. D.


    It is often desirable to sort data sets in ascending or descending order. This becomes more difficult for grouped data, i.e., multiple sets of data, where each set of data involves several measurements or related elements. The sort becomes increasingly cumbersome when more than a few elements exist for each data set. In order to achieve an efficient sorting process, an algorithm has been devised in which the maximum most significant element is found, and then compared to each element in succession. The program was written to handle the daily temperature readings of the Voyager spacecraft, particularly those related to the special tracking requirements of Voyager 2. By reducing each data set to a single representative number, the sorting process becomes very easy. The first step in the process is to reduce the data set of width 'n' to a data set of width '1'. This is done by representing each data set by a polynomial of length 'n' based on the differences of the maximum and minimum elements. These single numbers are then sorted and converted back to obtain the original data sets. Required input data are the name of the data file to read and sort, and the starting and ending record numbers. The package includes a sample data file, containing 500 sets of data with 5 elements in each set. This program will perform a sort of the 500 data sets in 3 - 5 seconds on an IBM PC-AT with a hard disk; on a similarly equipped IBM PC-XT the time is under 10 seconds. This program is written in BASIC (specifically the Microsoft QuickBasic compiler) for interactive execution and has been implemented on the IBM PC computer series operating under PC-DOS with a central memory requirement of approximately 40K of 8 bit bytes. A hard disk is desirable for speed considerations, but is not required. This program was developed in 1986.

  12. Sorting and selection in posets

    Daskalakis, Constantinos; Karp, Richard M.; Mossel, Elchanan;


    Classical problems of sorting and searching assume an underlying linear ordering of the objects being compared. In this paper, we study these problems in the context of partially ordered sets, in which some pairs of objects are incomparable. This generalization is interesting from a combinatorial...... from two decades ago by Faigle and Turán. In particular, we present the first algorithm that sorts a width-$w$ poset of size $n$ with query complexity $O(n(w+\\log n))$ and prove that this query complexity is asymptotically optimal. We also describe a variant of Mergesort with query complexity $O......(wn\\log\\frac{n}{w})$ and total complexity $O(w^{2}n\\log\\frac{n}{w})$; an algorithm with the same query complexity was given by Faigle and Turán, but no efficient implementation of that algorithm is known. Both our sorting algorithms can be applied with negligible overhead to the more general problem of reconstructing...

  13. Hybrid optical and acoustic force based sorting

    O'Mahoney, Paul; Brodie, Graham W.; Wang, Han; Demore, Christine E. M.; Cochran, Sandy; Spalding, Gabriel C.; MacDonald, Michael P.


    We report the combined use of optical sorting and acoustic levitation to give particle sorting. Differing sizes of microparticles are sorted optically both with and without the aid of acoustic levitation, and the results compared to show that the use of acoustic trapping can increase sorting efficiency. The use of a transparent ultrasonic transducer is also shown to streamline the integration of optics and acoustics. We also demonstrate the balance of optical radiation pressure and acoustic levitation to achieve vertical sorting.

  14. A Heapify Based Parallel Sorting Algorithm

    M. A.A.A. Hija


    Full Text Available Quick sort is a sorting algorithm whose worst case running time is θ(n2 on an input array of n numbers. It is the best practical for sorting because it has the advantage of sorting in place. Problem statement: Behavior of quick sort is complex, we proposed in-place 2m threads parallel heap sort algorithm which had advantage in sorting in place and had better performance than classical sequential quick sort in running time. Approach: The algorithm consisted of several stages, in first stage; it splits input data into two partitions, next stages it did the same partitioning for prior stage which had been spitted until 2 m partitions was reached equal to the number of available processors, finally it used heap sort to sort respectively ordered of non internally sorted partitions in parallel. Results: Results showed the speed of algorithm about double speed of classical Quick sort for a large input size. The number of comparisons needed was reduced significantly. Conclusion: In this study we had been proposed a sorting algorithm that uses less number of comparisons with respect to original quick sort that in turn requires less running time to sort the same input data.

  15. Deformability-based capsule sorting

    Le Goff, Anne; Munier, Nadege; Maire, Pauline; Edwards-Levy, Florence; Salsac, Anne-Virginie


    Many microfluidic devices have been developed for cancer diagnosis applications, most of which relying on costly antibodies. Since some cancer cells display abnormal mechanical properties, new sorting tools based on mechanical sensing are of particular interest. We present a simple, passive pinched flow microfluidic system for capsule sorting. The device consists of a straight microchannel containing a cylindrical obstacle. Thanks to a flow-focusing module placed at the channel entrance, capsules arrive well-centered in the vicinity of the obstacle. Pure size-sorting can be achieved at low shear rate. When increasing the shear rate, capsules are deformed in the narrow space between the pillar and the wall. The softer the capsule, the more tightly it wraps around the obstacle. After the obstacle, streamlines diverge, allowing for the separation between soft capsules, that follow central streamlines, and stiff capsules, that drift away from the obstacle with a wider angle. This proves that we have developed a flexible multipurpose sorting microsystem based on a simple design.

  16. Sorted.

    Towers, S


    Each year in Accident and Emergency an increasing number of young people present with acute problems related to social drugs. These problems range from mild symptoms to life-threatening conditions, many of which can be extremely difficult and time consuming for staff to manage. It has become apparent that as with sex the experimental age for taking drugs is getting younger as youths are now far more 'streetwise' than their predecessors. This is one of the main reasons for this paper being written; it is imperative that staff are equipped with the appropriate knowledge to deal with the challenge and are educated about the problems associated with current drug trends. This potentially improves the quality of care and, in turn, good communication improves relationships. Ecstasy is once again becoming increasingly popular within mainstream clubs, as recently highlighted in the media, and with it reappear its problems. This article discusses the historical aspects of Ecstasy and aims to educate staff about its use and effects and provides health promotion advice for those who are involved in the care of people who take Ecstasy.

  17. Swarm-Based Spatial Sorting

    Amos, Martyn


    Purpose: To present an algorithm for spatially sorting objects into an annular structure. Design/Methodology/Approach: A swarm-based model that requires only stochastic agent behaviour coupled with a pheromone-inspired "attraction-repulsion" mechanism. Findings: The algorithm consistently generates high-quality annular structures, and is particularly powerful in situations where the initial configuration of objects is similar to those observed in nature. Research limitations/implications: Experimental evidence supports previous theoretical arguments about the nature and mechanism of spatial sorting by insects. Practical implications: The algorithm may find applications in distributed robotics. Originality/value: The model offers a powerful minimal algorithmic framework, and also sheds further light on the nature of attraction-repulsion algorithms and underlying natural processes.

  18. Lipid sorting revealed by SANS

    We have investigated the lipid sorting in a binary small unilamellar vesicle (SUV) composed of cone-shaped (1,2-dihexanoyl-sn-glycero-3-phosphocholine: DHPC) and cylinder-shaped (1,2-dipalmitoyl-sn-glycero-3-phosphocholine: DPPC) lipids. In order to reveal the lipid sorting we adopted a contrast matching technique of small angle neutron scattering (SANS), which extracts the distribution of deuterated lipids in the bilayer quantitatively. The SANS profile of deuterated SUVs at the contrast matching condition showed a characteristic scattering profile, indicating an asymmetric distribution of cone-shaped lipids in the bilayer. The fitting of the observed SANS profile revealed that most DHPC molecules are localized in the outer leaflet, which supports that the shape of the lipid is strongly coupled with the membrane curvature. We compared the obtained asymmetric distribution of the cone-shaped lipids in the bilayer with the theoretical prediction based on the curvature energy model. (author)

    We create two overlapping one-dimensional optical lattices using a single laser beam, a spatial light modulator and a high numerical aperture lens. These lattices have the potential to trap single atoms, and using the dynamic capabilities of the spatial light modulator may shift and sort atoms to a minimum atom-atom separation of 1.52 μm. We show how a simple feedback circuit can compensate for the spatial light modulator's intensity modulation

  5. Design of Garbage Sorting Machine

    Stephen K. Adzimah


    Full Text Available Problem statement: Domestic waste collection, sorting and disposal are major problems in many developing countries such as Ghana. It is an undeniable fact that the environment has been engulfed in filth. This filth comprises of the garbage and waste generated in homes, workplace and industrial setups. Most of this waste has found its way into the streets, gutters, in and around the homes, dung hills and worst of all, water bodies, many of which are sources of the drinking water treated at high costs or not treated at all. Approach: Garbage needs to be sorted into various components and each of such components like textile materials, polythene, foodstuffs, metals and glassware would then have to be handled separately at the disposal or recycling site. Such a process required a certain degree of literacy, discipline and certain basic equipment, for example separate collector bins or sorting bags. In the developed world this is not much a problem because every home has different polythene bags into which the various constituents of domestic waste are put right at the generation point. Separate collection bins were also provided at vantage points for the various types of domestic garbage collection. In the developing countries these arrangements have not been feasible because of the level of literacy, lack of appreciation of the problem, non-availability of the different types of polythene bags and poverty. Currently, most garbage collection in the developing countries is done by depositing every thing into a single container from where they are hauled to be dumped in landfills or burned in incinerators. Refuse disposal by land filling requires a sizeable land for the sole purpose of refuse disposal. This may lead to (1: Encumbering large tracks of prime land, which could not be put to other uses (2: Pollution of ground water by the leachate from the landfills (3: Breeding of leaches, rodents, mosquitoes and (4: Generation of strong stench coming

    Pal, Mita; Mahanti, N C


    The present paper examines the behavior of Shift-insertion sort (insertion sort with shifting) for normal distribution inputs and is in continuation of our earlier work on this new algorithm for discrete distribution inputs, namely, negative binomial. Shift insertion sort is found more sensitive for main effects but not for all interaction effects compared to conventional insertion sort.

  7. Polarized sorting and trafficking in epithelial cells

    Xinwang Cao; Michal A Surma; Kai Simons


    The polarized distribution of proteins and lipids at the surface membrane of epithelial cells results in the formation of an apical and a basolateral domain,which are separated by tight junctions.The generation and maintenance of epithelial polarity require elaborate mechanisms that guarantee correct sorting and vectorial delivery of cargo molecules.This dynamic process involves the interaction of sorting signals with sorting machineries and the formation of transport carriers.Here we review the recent advances in the field of polarized sorting in epithelial cells.We especially highlight the role of lipid rafts in apical sorting.

  8. Hamaoka Nuclear Power Station of Chubu Electric Power Co. was busy with the construction of tsunami countermeasures. Aiming at restoring public's trust in nuclear power

    Direct cause of the accident at Tokyo Electric Power Co.'s Fukushima Daiichi Nuclear Power Station was known the loss of its function to cool reactors due to the tsunami, which flooded important facilities such as seawater intake pumps and emergency power supply systems. The dune embankment in front of Hamaoka Nuclear Power Station might act as a barrier to prevent tsunami-related flooding. As additional flooding prevention measure, on the station site, a new tsunami prevention wall reaching 18 m above sea level (total length: approx. 1.6 km) was under construction and in buildings, emergency seawater intake systems (EWS) of waterproof buildings with new seawater intake pumps and increased pressure resistance and water tightness of reactor building outer walls by adding double doors and new reinforced doors were in preparation. As for enhancement of emergency measures, multiple ways of ensuring the three functions necessary for continued cooling of reactors (power supply, water injection and heat removal) were deployed even if the functions of seawater intake pumps and emergency power supply systems are lost, and reactors can be reliably and safely brought to a state of cold shutdown. Completion of such new tsunami countermeasures were one year delayed and targeted at December 2013. (T. Tanaka)

  11. Sorting and Selection in Posets

    Daskalakis, Constantinos; Mossel, Elchanan; Riesenfeld, Samantha; Verbin, Elad


    Classical problems of sorting and searching assume an underlying linear ordering of the objects being compared. In this paper, we study a more general setting, in which some pairs of objects are incomparable. This generalization is relevant in applications related to rankings in sports, college admissions, or conference submissions. It also has potential applications in biology, such as comparing the evolutionary fitness of different strains of bacteria, or understanding input-output relations among a set of metabolic reactions or the causal influences among a set of interacting genes or proteins. Our results improve and extend results from two decades ago of Faigle and Tur\\'{a}n. A measure of complexity of a partially ordered set (poset) is its width. Our algorithms obtain information about a poset by queries that compare two elements. We present an algorithm that sorts, i.e. completely identifies, a width w poset of size n and has query complexity O(wn + nlog(n)), which is within a constant factor of the in...

  12. Fast Parallel Sorting Algorithms on GPUs

    Bilal Jan


    Full Text Available This paper presents a comparative analysis of the three widely used parallel sorting algorithms: Odd-Even sort, Rank sort and Bitonic sort in terms of sorting rate, sorting time and speed-up on CPU anddifferent GPU architectures. Alongside we have implemented novel parallel algorithm: min-max butterflynetwork, for finding minimum and maximum in large data sets. All algorithms have been implementedexploiting data parallelism model, for achieving high performance, as available on multi-core GPUsusing the OpenCL specification. Our results depicts minimum speed-up19x of bitonic sort against oddevensorting technique for small queue sizes on CPU and maximum of 2300x speed-up for very largequeue sizes on Nvidia Quadro 6000 GPU architecture. Our implementation of full-butterfly networksorting results in relatively better performance than all of the three sorting techniques: bitonic, odd-evenand rank sort. For min-max butterfly network, our findings report high speed-up of Nvidia quadro 6000GPU for high data set size reaching 224 with much lower sorting time.

  13. Recyclable Waste Paper Sorting Using Template Matching

    Osiur Rahman, Mohammad; Hussain, Aini; Scavino, Edgar; Hannan, M. A.; Basri, Hassan

    This paper explores the application of image processing techniques in recyclable waste paper sorting. In recycling, waste papers are segregated into various grades as they are subjected to different recycling processes. Highly sorted paper streams will facilitate high quality end products, and save processing chemicals and energy. Since 1932 to 2009, different mechanical and optical paper sorting methods have been developed to fill the demand of paper sorting. Still, in many countries including Malaysia, waste papers are sorted into different grades using manual sorting system. Due to inadequate throughput and some major drawbacks of mechanical paper sorting systems, the popularity of optical paper sorting systems is increased. Automated paper sorting systems offer significant advantages over human inspection in terms of fatigue, throughput, speed, and accuracy. This research attempts to develop a smart vision sensing system that able to separate the different grades of paper using Template Matching. For constructing template database, the RGB components of the pixel values are used to construct RGBString for template images. Finally, paper object grade is identified based on the maximum occurrence of a specific template image in the search image. The outcomes from the experiment in classification for White Paper, Old Newsprint Paper and Old Corrugated Cardboard are 96%, 92% and 96%, respectively. The remarkable achievement obtained with the method is the accurate identification and dynamic sorting of all grades of papers using simple image processing techniques.

    The analysis of extra-cellular neural recordings typically begins with careful spike sorting and all analysis of the data then rests on the correctness of the resulting spike trains. In many situations this is unproblematic as experimental and spike sorting procedures often focus on well isolated units. There is evidence in the literature, however, that errors in spike sorting can occur even with carefully collected and selected data. Additionally, chronically implanted electrodes and arrays ...

  17. Fast algorithms for sorting and searching strings

    Bentley, J.L. [Bell Labs., Murray Hill, NJ (United States); Sedgewick, R. [Princeton Univ., NJ (United States)


    We present theoretical algorithms for sorting and searching multikey data, and derive from them practical C implementations for applications in which keys are character strings. The sorting algorithm blends Quicksort and radix sort; it is competitive with the best known C sort codes. The searching algorithm blends tries and binary search trees; it is faster than hashing and other commonly used search methods. The basic ideas behind the algorithms date back at least to the 1960s, but their practical utility has been overlooked. We also present extensions to more complex string problems, such as partial-match searching.

  18. Design and realization of sort manipulator of crystal-angle sort machine

    Wang, Ming-shun; Chen, Shu-ping; Guan, Shou-ping; Zhang, Yao-wei


    It is a current tendency of development in automation technology to replace manpower with manipulators in working places where dangerous, harmful, heavy or repetitive work is involved. The sort manipulator is installed in a crystal-angle sort machine to take the place of manpower, and engaged in unloading and sorting work. It is the outcome of combing together mechanism, electric transmission, and pneumatic element and micro-controller control. The step motor makes the sort manipulator operate precisely. The pneumatic elements make the sort manipulator be cleverer. Micro-controller's software bestows some simple artificial intelligence on the sort manipulator, so that it can precisely repeat its unloading and sorting work. The combination of manipulator's zero position and step motor counting control puts an end to accumulating error in long time operation. A sort manipulator's design in the practice engineering has been proved to be correct and reliable.

    M. J. Mišić


    Full Text Available Graphics processing units (GPUs have been increasingly used for general-purpose computation in recent years. The GPU accelerated applications are found in both scientific and commercial domains. Sorting is considered as one of the very important operations in many applications, so its efficient implementation is essential for the overall application performance. This paper represents an effort to analyze and evaluate the implementations of the representative sorting algorithms on the graphics processing units. Three sorting algorithms (Quicksort, Merge sort, and Radix sort were evaluated on the Compute Unified Device Architecture (CUDA platform that is used to execute applications on NVIDIA graphics processing units. Algorithms were tested and evaluated using an automated test environment with input datasets of different characteristics. Finally, the results of this analysis are briefly discussed.

Using micro-data from the Current Population Survey for the years 1962-2011, it documents that in recessions the pool of unemployed shifts towards workers with high wages in their previous job. Moreover, it shows that these changes in the composition of the unemployed are mainly due to the higher cyclicalit...

  3. Enhancement of Selection, Bubble and Insertion Sorting Algorithm

    Muhammad Farooq Umar


    Full Text Available In everyday life there is a large amount of data to arrange because sorting removes any ambiguities and make the data analysis and data processing very easy, efficient and provides with cost less effort. In this study a set of improved sorting algorithms are proposed which gives better performance and design idea. In this study five new sorting algorithms (Bi-directional Selection Sort, Bi-directional bubble sort, MIDBiDirectional Selection Sort, MIDBidirectional bubble sort and linear insertion sort are presented. Bi-directional Selection Sort and MIDBiDirectional Selection Sort are the enhancement on basic selection sort while Bidirectional bubble sort and MIDBidirectional bubble sort are the enhancement on basic bubble sort by changing the selection and swapping mechanism of data for sorting. Enhanced sorting algorithms reduced the iteration by half and quarter times respectively. Asymptotically complexities of these algorithms are reduced to O (n2/2 and O (n2/4 from O (n2. Linear insertion sort is the enhancement of insertion sort by changing the design of algorithm (convert two loops to one loop. So asymptotically this algorithm is converted to linear time complexity from quadratic complexity. These sorting algorithms are described using C. The proposed algorithms are analyzed using asymptotic analysis and also using machine-running time and compared with their basic sorting algorithms. In this study we also discuss how the performance and complexity can be improved by optimizing the code and design.

  4. Below Regulatory Concern Owners Group: An evaluation of dry active waste sorting: Final report

    The objective of this research was to determine the accuracy of manual inspection of Dry Active Waste (DAW). Three studies were conducted at two nuclear power plants in which unmodified DAW waste streams of roughly 10,000 items each were inspected by technicians using pancake probes. Sorting performance was measured unobtrusively by intercepting the ''outflow'' from inspection stations. Verification of sorting accuracy was performed with a prototype, semi-automated sorting table employing a matrix of fixed plastic scintillation detectors. More than 30,000 items of trash were examined, classified, counted, and verified, and the composition of the ''inflow'' to the inspection stations was determined by reconstructing the ''outflow'' components, as determined during verification procedures. The results showed that between 1 and 19% of all items in each of the three DAW waste streams were contaminated at levels ≥100 ccpm. Sixty-two percent of the ''contaminated'' items in Study I, 87% of the contaminated items in Study II, and 97% of the contaminated items in Study III were detected. One-half to one percent of all items classified as <100 ccpm by technicians were actually ≥100 ccpm. False positive rates were very high in all three studies. The production rates and accuracy obtained on the semi-automated plastic scintillation sorting table used during the verification stages of this project greatly exceeded the rates for manual sorting. 9 figs., 13 tabs

  5. An Unsupervised Online Spike-Sorting Framework.

    Knieling, Simeon; Sridharan, Kousik S; Belardinelli, Paolo; Naros, Georgios; Weiss, Daniel; Mormann, Florian; Gharabaghi, Alireza


    Extracellular neuronal microelectrode recordings can include action potentials from multiple neurons. To separate spikes from different neurons, they can be sorted according to their shape, a procedure referred to as spike-sorting. Several algorithms have been reported to solve this task. However, when clustering outcomes are unsatisfactory, most of them are difficult to adjust to achieve the desired results. We present an online spike-sorting framework that uses feature normalization and weighting to maximize the distinctiveness between different spike shapes. Furthermore, multiple criteria are applied to either facilitate or prevent cluster fusion, thereby enabling experimenters to fine-tune the sorting process. We compare our method to established unsupervised offline (Wave_Clus (WC)) and online (OSort (OS)) algorithms by examining their performance in sorting various test datasets using two different scoring systems (AMI and the Adamos metric). Furthermore, we evaluate sorting capabilities on intra-operative recordings using established quality metrics. Compared to WC and OS, our algorithm achieved comparable or higher scores on average and produced more convincing sorting results for intra-operative datasets. Thus, the presented framework is suitable for both online and offline analysis and could substantially improve the quality of microelectrode-based data evaluation for research and clinical application.

  10. Quantum Database Search can do without Sorting

    Patel, A


    Sorting is a fundamental computational process, which facilitates subsequent searching of a database. It can be thought of as factorisation of the search process. The location of a desired item in a sorted database can be found by classical queries that inspect one letter of the label at a time. For an unsorted database, no such classical quick search algorithm is available. If the database permits quantum queries, however, then mere digitisation is sufficient for efficient search. Sorting becomes redundant with the quantum superposition of states. A quantum algorithm is written down which locates the desired item in an unsorted database a factor of two faster than the best classical algorithm can in a sorted database. This algorithm has close resemblance to the assembly process in DNA replication.

  14. A nonparametric Bayesian alternative to spike sorting

    Wood, Frank; Black, Michael J.


    The analysis of extra-cellular neural recordings typically begins with careful spike sorting and all analysis of the data then rests on the correctness of the resulting spike trains. In many situations this is unproblematic as experimental and spike sorting procedures often focus on well isolated units. There is evidence in the literature, however, that errors in spike sorting can occur even with carefully collected and selected data. Additionally, chronically implanted electrodes and arrays with fixed electrodes cannot be easily adjusted to provide well isolated units. In these situations, multiple units may be recorded and the assignment of waveforms to units may be ambiguous. At the same time, analysis of such data may be both scientifically important and clinically relevant. In this paper we address this issue using a novel probabilistic model that accounts for several important sources of uncertainty and error in spike sorting. In lieu of sorting neural data to produce a single best spike train, we estimate a probabilistic model of spike trains given the observed data. We show how such a distribution over spike sortings can support standard neuroscientific questions while providing a representation of uncertainty in the analysis. As a representative illustration of the approach, we analyzed primary motor cortical tuning with respect to hand movement in data recorded with a chronic multi-electrode array in non-human primates. We found that the probabilistic analysis generally agrees with human sorters but suggests the presence of tuned units not detected by humans. PMID:18602697

  17. Hash sort: A linear time complexity multiple-dimensional sort algorithm

    Gilreath, William F.


    Sorting and hashing are two completely different concepts in computer science, and appear mutually exclusive to one another. Hashing is a search method using the data as a key to map to the location within memory, and is used for rapid storage and retrieval. Sorting is a process of organizing data from a random permutation into an ordered arrangement, and is a common activity performed frequently in a variety of applications. Almost all conventional sorting algorithms work by comparison, and ...

  20. Oxide inspecting/sorting concepts. Revision 2

    The purpose of this document is to summarize the preferred methods for inspecting and sorting plutonium and uranium oxides in preparation for future processing. A limited number of commercially available systems were investigated in preparation for selecting the preferred candidate(s). A complete listing and description of all the oxides to be processed can be located in ''Materials Disposition Acceptance Specifications for the Plutonium Immobilization Project'', document number PIP-98-047. For the purposes of this document, they will be referred to simply as oxides, unless there is a specific characteristic requiring further explanation. The physical transfer of the oxides from a convenience can into a standard oxide can will occur in the High Contamination section of the Unpackaging/Sorting glovebox. The degree of oxide inspecting and sorting performed will depend on the processing that will occur after Unpackaging/Sorting, on the known condition of the oxide when it is first received and the degree of confidence in its condition. The order in which the steps are performed and what occurs in the individual steps may vary depending on the method selected. For the purpose of organization and to help clarify what may occur in the individual steps, the following guidelines are proposed for the Unpackaging/Sorting glovebox. Sorting will involve the capture and removal of foreign particles and/or to detain hard lumps for additional processing in Crush and Grind. Part of the sorting stage will involve reducing workable lumps (de-lumping) into a smaller particle size in preparation for the sizing stage. Sizing will involve classifying/grading the oxide powder into a particle size that is acceptable for the next processing stage. It could involve some mild form of processing (screening, eTc.), but is not expected to include any sophisticated type of processing. Inspection refers to the inspection of the final product to ensure it meets the particle size requirements for

  2. Sorting by Restricted-Length-Weighted Reversals

    Thach Cam Nguyen; Hieu Trung Ngo; Nguyen Bao Nguyen


    Classical sorting by reversals uses the unit-cost model, that is, each reversal consumes an equal cost. This model limits the biological meaning of sorting by reversal.Bender and his colleagues extended it by assigning a cost function f(l) = lα for all α≥ 0, where l is the length of the reversed subsequence. In this paper, we extend their results by considering a model in which long reversals are prohibited. Using the same cost function above for permitted reversals, we present tight or nearly tight bounds for the worst-case cost of sorting by reversals. Then we develop algorithms to approximate the optimal cost to sort a given 0/1 sequence as well as a given permutation. Our proposed problems are more biologically meaningful and more algorithmically general and challenging than the problem considered by Bender et al. Furthermore, our bounds are tight and nearly tight, whereas our algorithms provide good approximation ratios compared to the optimal cost to sort 0/1 sequences or permutations by reversals.

  4. Business intelligence

    Cebotarean Elena


    Full Text Available Business intelligence (BI refers to computer-based techniques used in spotting, digging-out, and analyzing business data, such as sales revenue by products and/or departments, or by associated costs and incomes. BI technologies provide historical, current, and predictive views of business operations. Common functions of business intelligence technologies are reporting, online analytical processing, analytics, data mining, business performance management, benchmarking, text mining, and predictive analytics. Business intelligence aims to support better business decision-making. Thus a BI system can be called a decision support system (DSS. Though the term business intelligence is sometimes used as a synonym for competitive intelligence, because they both support decision making, BI uses technologies, processes, and applications to analyze mostly internal, structured data and business processes while competitive intelligence gathers, analyzes and disseminates information with a topical focus on company competitors. Business intelligence understood broadly can include the subset of competitive intelligence.

  6. Assessing Incorrect Household Waste Sorting in a Medium-Sized Swedish City

    Kamran Rousta


    Full Text Available Source separation is a common method for dealing with the increasing problem of Municipal Solid Waste (MSW in society. The citizens are then responsible for separating waste fractions produced in their home. If the consumers fail to sort the waste according to the source separation scheme, it will lead to an ineffective system. The purpose of this paper is to analyze the environmental, economic and social aspects of incorrect waste sorting in a medium sized Swedish city that has established a source separation system. In order to determine the extent to which citizens correctly sort their waste, food waste (black bags and combustible fraction (white bags, were collected randomly from a residential area and categorized in different waste fractions. The results show that approximately 68 wt% of the waste in the white and 29 wt% in the black bags were not sorted correctly. This incorrect sorting accrues over 13 million SEK per year cost for this community. In order to improve the inhabitants’ participation in the waste management system, it is necessary to change different factors such as convenience and easy access to the recycling stations in the local MSW management systems as well as to review current regulation and policy.

    Blelloch, Guy E.; Fineman, Jeremy T.; Gibbons, Phillip B.; Gu, Yan; Shun, Julian


    Emerging memory technologies have a significant gap between the cost, both in time and in energy, of writing to memory versus reading from memory. In this paper we present models and algorithms that account for this difference, with a focus on write-efficient sorting algorithms. First, we consider the PRAM model with asymmetric write cost, and show that sorting can be performed in $O\\left(n\\right)$ writes, $O\\left(n \\log n\\right)$ reads, and logarithmic depth (parallel time). Next, we conside...

    Radionuclide methods suitable for sorting multi-component lump materials transported on conveyors are discussed. The methods considered use the different interaction of gamma- and X-radiations with materials of different atomic numbers. A comparison is made between a simple absorption method, a method using simultaneous absorption of photons of two different energies and a combination of the absorption and back-scattering methods. The fields of application of these methods serving to obtain output signals for the control of mechanical or pneumatic sorting devices are outlined. (author)

    Full Text Available Makalah ini mengetengahkan kajian implementasi dan performa proses pengurutan menggunakan dua algoritma yang berbeda, yaitu Insertion Sort dan Merge Sort. Pada tahap pertama, kedua algoritma tersebut diimplementasikan dalam bahasa C++ untuk mengurutkan sejumlah angka yang diketikkan oleh pengguna. Pada tahap kedua, kode sumber untuk kedua algoritma tersebut diubah untuk dapat mengurutkan angka yang dihasilkan secara acak dengan jumlah angka sebanyak permintaan dari pengguna. Untuk mengetahui seberapa baik performa dalam mengurutkan data, maka dalam tahap terakhir, kedua algoritma tersebut mengurutkan sejumlah angka acak dengan rentang jumlah yang sudah ditentukan dan hasilnya kemudian dibandingkan. Dari eksperimen yang sudah dilakukan, algoritma merge sort telah memperlihatkan performa yang lebih baik, khususnya untuk jumlah data yang banyak (> 10000. Adapun algoritma insertion sort memiliki keuntungan dalam hal kompleksitas algoritma yang lebih rendah terutama dalam kondisi best case dan karena tidak menggunakan rutin rekursi dalam proses pengurutan, maka tidak membutuhkan ruang penyimpanan atau memori sebanyak algoritma Merge Sort.

  8. PhySortR: a fast, flexible tool for sorting phylogenetic trees in R

    Stephens, Timothy G.; Bhattacharya, Debashish; Ragan, Mark A.


    A frequent bottleneck in interpreting phylogenomic output is the need to screen often thousands of trees for features of interest, particularly robust clades of specific taxa, as evidence of monophyletic relationship and/or reticulated evolution. Here we present PhySortR, a fast, flexible R package for classifying phylogenetic trees. Unlike existing utilities, PhySortR allows for identification of both exclusive and non-exclusive clades uniting the target taxa based on tip labels (i.e., leaves) on a tree, with customisable options to assess clades within the context of the whole tree. Using simulated and empirical datasets, we demonstrate the potential and scalability of PhySortR in analysis of thousands of phylogenetic trees without a priori assumption of tree-rooting, and in yielding readily interpretable trees that unambiguously satisfy the query. PhySortR is a command-line tool that is freely available and easily automatable. PMID:27190724

  9. Smart Sort: Design and Analysis of a Fast, Efficient and Robust Comparison Based Internal Sort Algorithm

    Singh, Niraj Kumar


    Smart Sort algorithm is a "smart" fusion of heap construction procedures (of Heap sort algorithm) into the conventional "Partition" function (of Quick sort algorithm) resulting in a robust version of Quick sort algorithm. We have also performed empirical analysis of average case behavior of our proposed algorithm along with the necessary theoretical analysis for best and worst cases. Its performance was checked against some standard probability distributions, both uniform and non-uniform, like Binomial, Poisson, Discrete & Continuous Uniform, Exponential, and Standard Normal. The analysis exhibited the desired robustness coupled with excellent performance of our algorithm. Although this paper assumes the static partition ratios, its dynamic version is expected to yield still better results.

  12. A mower detector to judge soil sorting

    Bramlitt, E.T.; Johnson, N.R. [Thermo Nuclear Services, Inc., Albuquerque, NM (United States)


    Thermo Nuclear Services (TNS) has developed a mower detector as an inexpensive and fast means for deciding potential value of soil sorting for cleanup. It is a shielded detector box on wheels pushed over the ground (as a person mows grass) at 30 ft/min with gamma-ray counts recorded every 0.25 sec. It mirror images detection by the TNS transportable sorter system which conveys soil at 30 ft/min and toggles a gate to send soil on separate paths based on counts. The mower detector shows if contamination is variable and suitable for sorting, and by unique calibration sources, it indicates detection sensitivity. The mower detector has been used to characterize some soil at Department of Energy sites in New Jersey and South Carolina.

    Nucleolar isolation allows exhaustive characterization of the nucleolar content. Centrifugation-based protocols are not adapted to isolation of nucleoli directly from a plant tissue because of copurification of cellular debris. We describe here a method that allows the purification of nucleoli using fluorescent-activated cell sorting from Arabidopsis thaliana leaves. This approach requires the expression of a specific nucleolar protein such as fibrillarin fused to green fluorescent protein in planta. PMID:27576720

The algorithm first constructs a network in terms of n*n Toffoli gates read from left to right. The number of gates in the circuit produced by our algorithm is then reduced by template matching and removing useless gates from the network. We have also compared the efficiency of the proposed method with the existing ones.

  2. How Schwann Cells Sort Axons: New Concepts.

    Feltri, M Laura; Poitelon, Yannick; Previtali, Stefano Carlo


    Peripheral nerves contain large myelinated and small unmyelinated (Remak) fibers that perform different functions. The choice to myelinate or not is dictated to Schwann cells by the axon itself, based on the amount of neuregulin I-type III exposed on its membrane. Peripheral axons are more important in determining the final myelination fate than central axons, and the implications for this difference in Schwann cells and oligodendrocytes are discussed. Interestingly, this choice is reversible during pathology, accounting for the remarkable plasticity of Schwann cells, and contributing to the regenerative potential of the peripheral nervous system. Radial sorting is the process by which Schwann cells choose larger axons to myelinate during development. This crucial morphogenetic step is a prerequisite for myelination and for differentiation of Remak fibers, and is arrested in human diseases due to mutations in genes coding for extracellular matrix and linkage molecules. In this review we will summarize progresses made in the last years by a flurry of reverse genetic experiments in mice and fish. This work revealed novel molecules that control radial sorting, and contributed unexpected ideas to our understanding of the cellular and molecular mechanisms that control radial sorting of axons.

To assess this hypothesis, we investigate the sorting of lipid analog dye trace components be...

  4. Mechatronic Design and Control of a Waste Paper Sorting System for Efficient Recycling

    Venditti, R. A.; Ramasubramanian, M. K.


    Sorting of paper into compatible grades is a necessary step prior to recycling. Current method of manually sorting is tedious, slow, and expensive. Hence, significant part of the waste paper stream is sent to the landfill. High speed automation of the sorting process will improve the cost efficiency and increase the amount of paper recycled significantly. There have been recent developments in automation of this process. Mechanisms for the distribution of the papers from a bale onto a moving conveyor and the pneumatic actuation to deflect papers into different streams are well established. Correct identification of the sample in real-time before the sample reaches the actuation station still remains a challenge since different types of paper and board samples are mixed in a waste stream, and has a lot of variation in terms of color, chemical composition, coating, and prints in black and white and color to different degrees. This is primarily due to the lack of satisfactory sensors and sensor fusion algorithms for sample identification in real-time. In this report, we identify key parameters that must be measured (lignin, stiffness, color gloss), sensor design, and integration of the output from sensors to interpret the type of sample using a fuzzy inference system. Results show that the sensor system proposed is capable of identifying the samples at 90% accuracy. The sensor system can be integrated onto a conveyor and actuation system for automated sorting.

  9. The future electricity business

    The transition of the electricity business into the competitive market will result in change as significant as that brought about by the PC or the deregulation of telecommunications,and with it opportunities for new products, service, and technologies, particularly to support an increase in distributed generation. The electricity business has been viewed as having three building blocks--generation, transmission, and distribution. Almost all investments in these three sectors historically have been made by utilities, but now these investments have begun to be made by customers or new entrants under a competitive market model. With the high-voltage transmission system largely built, the business focus will shift to efficient utilization of that infrastructure through investments in grid automation control, communications, and network management. And while the primary function of the distribution system--connecting customers to the utility grid--will remain unchanged, there will be new requirements on the distribution system to integrate distributed technologies and customer micro grids. Generation power plants are as likely to be located at customer sites as at utility or central-station sites. Customers may choose to create micro grids that are locally self sufficient and may or may not be connected to the utility grid. The characteristics of the distribution grid are likely to change from a one-way system in which power flows from utility central-station power plants to customers, to a two-way system in which power may flow in either direction. Hence, the focus will increasingly shift to integration of portfolio of distributed technologies. The opening of the electricity business to competition also opens new markets and business opportunities for new entrants

  14. Sorting N-Elements Using Natural Order: A New Adaptive Sorting Approach

    Shamim Akhter


    Full Text Available Problem statement: Researchers focused their attention on optimally adaptive sorting algorithm and illustrated a need to develop tools for constructing adaptive algorithms for large classes of measures. In adaptive sorting algorithm the run time for n input data smoothly varies from O(n to O(nlogn, with respect to several measures of disorder. Questions were raised whether any approach or technique would reduce the run time of adaptive sorting algorithm and provide an easier way of implementation for practical applications. Approach: The objective of this study is to present a new method on natural sorting algorithm with a run time for n input data O(n to O(nlogm, where m defines a positive value and surrounded by 50% of n. In our method, a single pass over the inputted data creates some blocks of data or buffers according to their natural sequential order and the order can be in ascending or descending. Afterward, a bottom up approach is applied to merge the naturally sorted subsequences or buffers. Additionally, a parallel merging technique is successfully aggregated in our proposed algorithm. Results: Experiments are provided to establish the best, worst and average case runtime behavior of the proposed method. The simulation statistics provide same harmony with the theoretical calculation and proof the method efficiency. Conclusion: The results indicated that our method uses less time as well as acceptable memory to sort a data sequence considering the natural order behavior and applicable to the realistic researches. The parallel implementation can make the algorithm for efficient in time domain and will be the future research issue.

  15. Online sorting of recovered wood waste by automated XRF-technology: part II. Sorting efficiencies.

    Hasan, A Rasem; Solo-Gabriele, Helena; Townsend, Timothy


    Sorting of waste wood is an important process practiced at recycling facilities in order to detect and divert contaminants from recycled wood products. Contaminants of concern include arsenic, chromium and copper found in chemically preserved wood. The objective of this research was to evaluate the sorting efficiencies of both treated and untreated parts of the wood waste stream, and metal (As, Cr and Cu) mass recoveries by the use of automated X-ray fluorescence (XRF) systems. A full-scale system was used for experimentation. This unit consisted of an XRF-detection chamber mounted on the top of a conveyor and a pneumatic slide-way diverter which sorted wood into presumed treated and presumed untreated piles. A randomized block design was used to evaluate the operational conveyance parameters of the system, including wood feed rate and conveyor belt speed. Results indicated that online sorting efficiencies of waste wood by XRF technology were high based on number and weight of pieces (70-87% and 75-92% for treated wood and 66-97% and 68-96% for untreated wood, respectively). These sorting efficiencies achieved mass recovery for metals of 81-99% for As, 75-95% for Cu and 82-99% of Cr. The incorrect sorting of wood was attributed almost equally to deficiencies in the detection and conveyance/diversion systems. Even with its deficiencies, the system was capable of producing a recyclable portion that met residential soil quality levels established for Florida, for an infeed that contained 5% of treated wood.

  16. Stochastic Models of Vesicular Sorting in Cellular Organelles

    Vagne, Quentin


    The proper sorting of membrane components by regulated exchange between cellular organelles is crucial to intra-cellular organization. This process relies on the budding and fusion of transport vesicles, and should be strongly influenced by stochastic fluctuations considering the relatively small size of many organelles. We identify the perfect sorting of two membrane components initially mixed in a single compartment as a first passage process, and we show that the mean sorting time exhibits two distinct regimes as a function of the ratio of vesicle fusion to budding rates. Low ratio values leads to fast sorting, but results in a broad size distribution of sorted compartments dominated by small entities. High ratio values result in two well defined sorted compartments but is exponentially slow. Our results suggests an optimal balance between vesicle budding and fusion for the rapid and efficient sorting of membrane components, and highlight the importance of stochastic effects for the steady-state organizati...

  20. Lateral chirality-sorting optical forces

    Hayat, Amaury; Mueller, J. P. Balthasar; Capasso, Federico


    The transverse component of the spin angular momentum of evanescent waves gives rise to lateral optical forces on chiral particles, which have the unusual property of acting in a direction in which there is neither a field gradient nor wave propagation. Because their direction and strength depends on the chiral polarizability of the particle, they act as chirality-sorting and may offer a mechanism for passive chirality spectroscopy. The absolute strength of the forces also substantially exceeds that of other recently predicted sideways optical forces. PMID:26453555

  2. Sorting waste - A question of good will

    TS Department - FM Group


    In order to minimise waste-sorting costs, CERN provides two types of container at the entrance of buildings: a green plastic container for paper/cardboard and a metal container for household-type waste. We regret that recently there has been a significant decrease in the extent to which these types of waste are sorted, for example green containers have been found to hold assorted waste such as cardboard boxes filled with polystyrene, bubble-wrap or even plastic bottles, yoghurt pots, etc. Checks have shown that this 'non-compliant' waste does not come from the rubbish bins emptied by the cleaners but is deposited there directly by inconsiderate users. During the months of October and November alone, for example, only 15% of the waste from the paper/cardboard containers was recycled and the remaining 85% had to be incinerated, which entails a high cost for CERN. You should note that once an item of non-compliant waste is found in a green container its contents are immediately sent as waste to be incinerated ...

  3. Sorting and recycling of domestic waste. Review of occupational health problems and their possible causes.

    Poulsen, O M; Breum, N O; Ebbehøj, N; Hansen, A M; Ivens, U I; van Lelieveld, D; Malmros, P; Matthiasen, L; Nielsen, B H; Nielsen, E M


    In order to reduce the strain on the environment from the deposition of waste in landfills and combustion at incineration plants, several governments throughout the industrialized world have planned greatly increased recycling of domestic waste by the turn of the millennium. To implement the plans, new waste recycling facilities are to be built and the number of workers involved in waste sorting and recycling will increase steadily during the next decade. Several studies have reinforced the hypothesis that exposure to airborne microorganisms and the toxic products thereof are important factors causing a multitude of health problems among workers at waste sorting and recycling plants. Workers at transfer stations, landfills and incineration plants may experience an increased risk of pulmonary disorders and gastrointestinal problems. High concentrations of total airborne dust, bacteria, faecal coliform bacteria and fungal spores have been reported. The concentrations are considered to be sufficiently high to cause adverse health effects. In addition, a high incidence of lower back injuries, probably due to heavy lifting during work, has been reported among workers at landfills and incineration plants. Workers involved in manual sorting of unseparated domestic waste, as well as workers at compost plants experience more or less frequent symptoms of organic dust toxic syndrome (ODTS) (cough, chest-tightness, dyspnoea, influenza-like symptoms such as chills, fever, muscle ache, joint pain, fatigue and headache), gastrointestinal problems such as nausea and diarrhoea, irritation of the skin, eye and mucous membranes of the nose and upper airways, etc. In addition cases of severe occupational pulmonary diseases (asthma, alveolitis, bronchitis) have been reported. Manual sorting of unseparated domestic waste may be associated with exposures to large quantities of airborne bacteria and endotoxin. Several work functions in compost plants can result in very high exposure to

  6. Sorting during Migration of Aeolian Megaripples

    Sullivan, R. J., Jr.; Zimbelman, J. R.


    Aeolian sediments commonly are well sorted. However, aeolian megaripples (aka coarse-grained ripples or granule ripples) have bimodal grain size-frequencies. Distinguishing aeolian megaripple deposits from mixed grain size fluvial deposits is important, particularly for martian sedimentary rocks where implications for flowing water in the martian past (if revealed by legitimate fluvial deposits) are important mission drivers for rovers and landers. Aeolian megaripples are relatively minor components of terrestrial aeolian settings (e.g., as interdune features), but on Mars, megaripples have been encountered in many locations by landers and rovers, are durable due to indurated, armoring surface layers of very coarse sand, and therefore are likely candidates for preservation in the martian sedimentary rock record. Unfortunately, megaripple deposits preserved in martian sedimentary rocks must be recognized with much less data or context than obtained typically during terrestrial fieldwork. We have undertaken wind tunnel experiments and fieldwork to assist interpretations distinguishing aeolian megaripple deposits from mixed grain fluvial materials. Lags of coarse or very coarse sand from ancient aeolian environments within the White Rim Sandstone, Canyonlands NP, UT, and at some localities along the J2 Unconformity at Buckhorn Wash, UT, are well sorted, with a sharply defined maximum grain size in each case. We conducted wind tunnel experiments to explore whether the well-sorted, sharp cutoff in maximum grain size of the coarse fraction in these deposits could be diagnostic of aeolian megaripple formation and migration. Wind tunnel experiments involved 250 μm sand saltating against 600-2800 μm grains. For a given wind tunnel speed, only a narrow grain size range appeared on megaripple surfaces as these bedforms developed spontaneously from the bed; somewhat finer grains migrated rapidly downwind, while slightly coarser grains remained immobile. The physics of

  7. Faster Radix Sort via Virtual Memory and Write-Combining

    Wassenberg, Jan


    Sorting algorithms are the deciding factor for the performance of common operations such as removal of duplicates or database sort-merge joins. This work focuses on 32-bit integer keys, optionally paired with a 32-bit value. We present a fast radix sorting algorithm that builds upon a microarchitecture-aware variant of counting sort. Taking advantage of virtual memory and making use of write-combining yields a per-pass throughput corresponding to at least 88 % of the system's peak memory bandwidth. Our implementation outperforms Intel's recently published radix sort by a factor of 1.5. It also compares favorably to the reported performance of an algorithm for Fermi GPUs when data-transfer overhead is included. These results indicate that scalar, bandwidth-sensitive sorting algorithms remain competitive on current architectures. Various other memory-intensive applications can benefit from the techniques described herein.

  8. 评“地勘基金”和“商业跟进”的定位和排序--事关地质找矿体制和机制的改革%Review on the Positioning and Sorting of Geological Exploration Fund and Business Investment Follow-up-On the Reform of System and Mechanism of Geological Prospecting



      This paper points out that putting business follow-up before fund connection reflects the responsibility of government and business entity, which is a major issue of principle concerning institutional reform of geological prospecting under the socialist market system. Therefore, we should voice our firm and unswerving support to this principle. The funds for geological prospecting established by the central government is intended to regulate and control the investment in geological exploration, reduce the risk of prospecting, and promote business investment follow- up. This paper analyses the main disadvantages with regard to mismatches of funds for geological prospecting which occurred due to the situation changes in some provinces and regions. These disadvantages include:unfair competition in the market was formed;the basic role of the market in the allocation of resources was repelled;thus long-term mechanism for investment in geological exploration became more difficult to generate. On account of this, this paper offers some suggestions:the pattern of“alliance of prospecting”built with funds for geological prospecting and social funds in Henan province may be worth listening to. Mineral resource compensation standards must be improved, and the ownership interests diverted by the price should be controlled. In addition, as for the intervention in the exploration, the government must insist on separating government functions from enterprise management operation.%  把“商业跟进”放在“基金衔接”之前,体现了政府定位和企业主体,是社会主义市场经济体制下地质找矿体制、机制改革的重大原则问题,必须旗帜鲜明地予以坚持。中央出台“地质勘查基金”意图是作为“周转金”,主要用来调控矿产勘查投入,降低找矿风险,促进商业投资的跟进。因形势变化促成某些省、区“地勘基金”的错位,这种“错位”

    Marital sorting along education, income and other salient dimensions is well-documented for many countries. The degree of marital sorting may influence income inequality, intergenerational mobility, and household labor supply, and other economic outcomes. Marital sorting is thought to arise from some combination of people’s preferences and constraints on their choice sets. However, separating these two causes is difficult because typical data sets provide information on either a person’s spou...

  16. Radiometric sorting of Rio Algom uranium ore

    An ore sample of about 0.2 percent uranium from Quirke Mine was subjected to radiometric sorting by Ore Sorters Limited. Approximately 60 percent of the sample weight fell within the sortable size range: -150 + 25 mm. Rejects of low uranium content (2 (2 counts/in2) but only 7.6 percent of the ore, by weight, was discarded. At 0.8-0.9 counts/cm2 (5-6 counts/in2) a significant amount of rejects was removed (> 25 percent) but the uranium loss was unacceptably high (7.7 percent). Continuation of the testwork to improve the results is proposed by trying to extend the sortable size range and to reduce the amount of fines during crushing

  1. Solution structure of human sorting nexin 22.

    Song, Jikui; Zhao, Kate Qin; Newman, Carrie L Loushin; Vinarov, Dmitriy A; Markley, John L


    The sorting nexins (SNXs) constitute a large group of PX domain-containing proteins that play critical roles in protein trafficking. We report here the solution structure of human sorting nexin 22 (SNX22). Although SNX22 has <30% sequence identity with any PX domain protein of known structure, it was found to contain the alpha/beta fold and compact structural core characteristic of PX domains. Analysis of the backbone dynamics of SNX22 by NMR relaxation measurements revealed that the two walls of the ligand binding cleft undergo internal motions: on the picosecond timescale for the beta1/beta2 loop and on the micro- to millisecond timescale for the loop between the polyproline motif and helix alpha2. Regions of the SNX22 structure that differ from those of other PX domains include the loop connecting strands beta1 and beta2 and the loop connecting helices alpha1 and alpha2, which appear to be more mobile than corresponding loops in other known structures. The interaction of dibutanoyl-phosphatidylinositol-3-phosphate (dibutanoyl-PtdIns(3)P) with SNX22 was investigated by an NMR titration experiment, which identified the binding site in a basic cleft and indicated that ligand binding leads only to a local structural rearrangement as has been found with other PX domains. Because motions in the loops are damped out when dibutanoyl-PtdIns(3)P binds, entropic effects could contribute to the lower affinity of SNX22 for this ligand compared to other PX domains.

  2. Learning sorting algorithms through visualization construction

    Cetin, Ibrahim; Andrews-Larson, Christine


    Recent increased interest in computational thinking poses an important question to researchers: What are the best ways to teach fundamental computing concepts to students? Visualization is suggested as one way of supporting student learning. This mixed-method study aimed to (i) examine the effect of instruction in which students constructed visualizations on students' programming achievement and students' attitudes toward computer programming, and (ii) explore how this kind of instruction supports students' learning according to their self-reported experiences in the course. The study was conducted with 58 pre-service teachers who were enrolled in their second programming class. They expect to teach information technology and computing-related courses at the primary and secondary levels. An embedded experimental model was utilized as a research design. Students in the experimental group were given instruction that required students to construct visualizations related to sorting, whereas students in the control group viewed pre-made visualizations. After the instructional intervention, eight students from each group were selected for semi-structured interviews. The results showed that the intervention based on visualization construction resulted in significantly better acquisition of sorting concepts. However, there was no significant difference between the groups with respect to students' attitudes toward computer programming. Qualitative data analysis indicated that students in the experimental group constructed necessary abstractions through their engagement in visualization construction activities. The authors of this study argue that the students' active engagement in the visualization construction activities explains only one side of students' success. The other side can be explained through the instructional approach, constructionism in this case, used to design instruction. The conclusions and implications of this study can be used by researchers and

  3. The influence of caches on the performance of sorting

    LaMarca, A.; Ladner, R.E. [Univ. of Washington, Seattle, WA (United States)


    We investigate the effect that caches have on the performance of sorting algorithms both experimentally and analytically. To address the performance problems that high cache miss penalties introduce we restructure heapsort, mergesort and quicksort in order to improve their cache locality. For all three algorithms the improvement in cache performance leads to a reduction in total execution time. We also investigate the performance of radix sort. Despite the extremely low instruction count incurred by this linear sorting algorithm, its relatively poor cache performance results in worse overall performance than the efficient comparison based sorting algorithms.

Parallel identification of target specimens through image analysis can sort based on highly tuneable selection criteria and can enable high-speed optical sorting when...... matched with a rapidly reconfigurable optical sorting field. We demonstrate the potential of such a system using colloidal polystyrene microspheres. By combining machine vision with a parallel add-on optical manipulation scheme, we were able to move identified particles over a distance of several hundred...

  6. A Sort-Last Rendering System over an Optical Backplane

    Yasuhiro Kirihata; Jason Leigh; Chaoyue Xiong; Tadao Murata


    Sort-Last is a computer graphics technique for rendering extremely large data sets on clusters of computers. Sort-Last works by dividing the data set into even-sized chunks for parallel rendering and then composing the images to form the final result. Since sort-last rendering requires the movement of large amounts of image data among cluster nodes, the network interconnecting the nodes becomes a major bottleneck. In this paper, we describe a sort-last rendering system implemented on a cluste...

  7. Pattern matching based active optical sorting of colloids/cells

    We report active optical sorting of colloids/cells by employing a cross correlation based pattern matching technique for selection of the desired objects and thereafter sorting using dynamically controllable holographic optical traps. The problem of possible collision between the different sets of objects during sorting was avoided by raising one set of particles to a different plane. We also present the results obtained on using this approach for some representative applications such as sorting of silica particles of two different sizes, of closely packed colloids and of white blood cells and red blood cells from a mixture of the two.

  9. An analytical comparison of the information in sorted and non-sorted cosine-tuned spike activity

    Won, D. S.; Tiesinga, P. H. E.; Henriquez, C. S.; Wolf, P. D.


    Spike sorting is a technologically expensive component of the signal processing chain required to interpret population spike activity acquired in a neuromotor prosthesis. No systematic analysis of the value of spike sorting has been carried out, and little is known about the effects of spike sorting error on the ability of a brain-machine interface (BMI) to decode intended motor commands. We developed a theoretical framework to examine the effects of spike processing on the information available to a BMI decoder. We computed the mutual information in neural activity in a simplified model of directional cosine tuning to compare the effects of pooling activity from up to four neurons to the effects of sorting with varying amounts of spike error. The results showed that information in a small population of cosine-tuned neurons is maximized when the responses are sorted and there is diverse tuning of units, but information was affected little when pooling units with similar preferred directions. Spike error had adverse effects on information, such that non-sorted population activity had 79-92% of the information in its sorted counterpart for reasonable amounts of detection and sorting error and for units with moderate differences in preferred direction. This quantification of information loss associated with pooling units and with spike detection and sorting error will help to guide the engineering decisions in designing a BMI spike processing system.

  3. Multiphase ferrofluid flows for micro-particle sorting

    Zhou, Ran; Wang, Cheng


    Utilizing negative magnetophoresis, ferrofluids have demonstrated great potential for sorting nonmagnetic micro-particles by size. Most of the existing techniques use single phase ferrofluids by pushing micro-particles to channel walls; the sorting speed is thus hindered. We demonstrate a novel sorting strategy by co-flowing a ferrofluid and a non-magnetic fluid in microchannels. Due to the magnetic force, the particles migrate across the ferrofluid stream at size-dependent velocities as they travel downstream. The laminar interface between the two fluids functions as a virtual boundary to accumulate particles, resulting in effective separation of particles. A stable and sharp interface is important to the success of this sorting technique. We investigate several factors that affect sorting efficiency, including magnetic field, susceptibility difference of the fluids, flow velocity, and channel geometry.

  4. Efficient External Sorting on Flash Memory Embedded Devices

    Tyler Cossentine


    Full Text Available Many embedded system applications involve storing and querying large datasets. Existing research in thisarea has focused on adapting and applying conventional database algorithms to embedded devices.Algorithms designed for processing queries on embedded devices must be able to execute given the smallamount of available memory and energy constraints. Most embedded devices use flash memory to storelarge amounts of data. Flash memory has unique performance characteristics that can be exploited toimprove algorithm performance. In this paper, we describe the Flash MinSort external sorting algorithmthat uses an index, generated at runtime, to take advantage of fast random reads in flash memory. Thisalgorithm adapts to the amount of memory available and performs best in applications where sort keys areclustered. Experimental results show that Flash MinSort is two to ten times faster than previousapproaches for small memory sizes where external merge sort is not executable.

  5. Help the planet by sorting your waste!


    Paper and cardboard waste comes in various forms, from newspapers to the toughest cardboard. Every year CERN dispatches about 200 tonnes of paper and cardboard to a recycling plant, but this is still too little when you take into consideration the tonnes of paper and cardboard that are still thrown out as part of ordinary rubbish or are incorrectly sorted into other rubbish skips.   Each office is equipped with a wastepaper bin, and a paper and cardboard container is available near every building. Cardboard boxes should be folded before they are placed in the containers in order to save space. Please note: Here are some sobering statistics: - 2 to 3 tonnes of wood pulp are required to manufacture 1 tonne of paper. - Each tonne of recycled paper means that we can save approximately 15 trees and substantial amounts of the water that is needed to extract cellulose (60 litres of water per kilo of paper). - A production of 100% recycled paper represents a 90% saving in water. - 5000 kWh of e...

  6. Microfluidic-chip platform for cell sorting

    Malik, Sarul; Balyan, Prerna; Akhtar, J.; Agarwal, Ajay


    Cell sorting and separation are considered to be very crucial preparatory steps for numerous clinical diagnostics and therapeutics applications in cell biology research arena. Label free cell separation techniques acceptance rate has been increased to multifold by various research groups. Size based cell separation method focuses on the intrinsic properties of the cell which not only avoids clogging issues associated with mechanical and centrifugation filtration methods but also reduces the overall cost for the process. Consequentially flow based cell separation method for continuous flow has attracted the attention of millions. Due to the realization of structures close to particle size in micro dimensions, the microfluidic devices offer precise and rapid particle manipulation which ultimately leads to an extraordinary cell separation results. The proposed microfluidic device is fabricated to separate polystyrene beads of size 1 µm, 5 µm, 10 µm and 20 µm. The actual dimensions of blood corpuscles were kept in mind while deciding the particle size of polystyrene beads which are used as a model particles for study.

  7. Nanoplasmonic lenses for bacteria sorting (Presentation Recording)

    Zhu, Xiangchao; Yanik, Ahmet A.


    We demonstrate that patches of two dimensional arrays of circular plasmonic nanoholes patterned on gold-titanium thin film enables subwavelength focusing of visible light in far field region. Efficient coupling of the light with the excited surface plasmon at metal dielectric interface results in strong light transmission. As a result, surface plasmon plays an important role in the far field focusing behavior of the nanohole-aperture patches device. Furthermore, the focal length of the focused beam was found to be predominantly dependent on the overall size of the patch, which is in good agreement with that calculated by Rayleigh-Sommerfield integral formula. The focused light beam can be utilized to separate bio-particles in the dynamic range from 0.1 μm to 1 μm through mainly overcoming the drag force induced by fluid flow. In our proposed model, focused light generated by our plasmonic lenses will push the larger bio-particles in size back to the source of fluid flow and allow the smaller particles to move towards the central aperture of the patch. Such a new kind of plasmonic lenses open up possibility of sorting bacterium-like particles with plasmonic nanolenses, and also represent a promising tool in the field of virology.

  20. Microfluidic EmbryoSort technology: towards in flow analysis, sorting and dispensing of individual vertebrate embryos

    Fuad, Nurul M.; Wlodkowic, Donald


    The demand to reduce the numbers of laboratory animals has facilitated the emergence of surrogate models such as tests performed on zebrafish (Danio rerio) or African clawed frog's (Xenopus levis) eggs, embryos and larvae. Those two model organisms are becoming increasingly popular replacements to current adult animal testing in toxicology, ecotoxicology and also in drug discovery. Zebrafish eggs and embryos are particularly attractive for toxicological analysis due their size (diameter 1.6 mm), optical transparency, large numbers generated per fish and very straightforward husbandry. The current bottleneck in using zebrafish embryos for screening purposes is, however, a tedious manual evaluation to confirm the fertilization status and subsequent dispensing of single developing embryos to multitier plates to perform toxicity analysis. Manual procedures associated with sorting hundreds of embryos are very monotonous and as such prone to significant analytical errors due to operator's fatigue. In this work, we present a proofof- concept design of a continuous flow embryo sorter capable of analyzing, sorting and dispensing objects ranging in size from 1.5 - 2.5 mm. The prototypes were fabricated in polymethyl methacrylate (PMMA) transparent thermoplastic using infrared laser micromachining. The application of additive manufacturing processes to prototype Lab-on-a-Chip sorters using both fused deposition manufacturing (FDM) and stereolithography (SLA) were also explored. The operation of the device was based on a revolving receptacle capable of receiving, holding and positioning single fish embryos for both interrogation and subsequent sorting. The actuation of the revolving receptacle was performed using a DC motor and/or microservo motor. The system was designed to separate between fertilized (LIVE) and non-fertilized (DEAD) eggs, based on optical transparency using infrared (IR) emitters and receivers.

  5. Microspherical photonics: Sorting resonant photonic atoms by using light

    Maslov, Alexey V., E-mail: [University of Nizhny Novgorod, Nizhny Novgorod (Russian Federation); Astratov, Vasily N., E-mail: [Department of Physics and Optical Science, Center for Optoelectronics and Optical Communications, University of North Carolina at Charlotte, Charlotte, North Carolina 28223-0001 (United States)


    A method of sorting microspheres by resonant light forces in vacuum, air, or liquid is proposed. Based on a two-dimensional model, it is shown that the sorting can be realized by allowing spherical particles to traverse a focused beam. Under resonance with the whispering gallery modes, the particles acquire significant velocity along the beam direction. This opens a unique way of large-volume sorting of nearly identical photonic atoms with 1/Q accuracy, where Q is the resonance quality factor. This is an enabling technology for developing super-low-loss coupled-cavity structures and devices.

  14. Running worms: C. elegans self-sorting by electrotaxis.

    Xavier Manière

    Full Text Available The nematode C. elegans displays complex dynamical behaviors that are commonly used to identify relevant phenotypes. Although its maintenance is straightforward, sorting large populations of worms when looking for a behavioral phenotype is difficult, time consuming and hardly quantitative when done manually. Interestingly, when submitted to a moderate electric field, worms move steadily along straight trajectories. Here, we report an inexpensive method to measure worms crawling velocities and sort them within a few minutes by taking advantage of their electrotactic skills. This method allows to quantitatively measure the effect of mutations and aging on worm's crawling velocity. We also show that worms with different locomotory phenotypes can be spatially sorted, fast worms traveling away from slow ones. Group of nematodes with comparable locomotory fitness could then be isolated for further analysis. C. elegans is a growing model for neurodegenerative diseases and using electrotaxis for self-sorting can improve the high-throughput search of therapeutic bio-molecules.

  15. Sorting on STAR. [CDC computer algorithm timing comparison

    Stone, H. S.


    Timing comparisons are given for three sorting algorithms written for the CDC STAR computer. One algorithm is Hoare's (1962) Quicksort, which is the fastest or nearly the fastest sorting algorithm for most computers. A second algorithm is a vector version of Quicksort that takes advantage of the STAR's vector operations. The third algorithm is an adaptation of Batcher's (1968) sorting algorithm, which makes especially good use of vector operations but has a complexity of N(log N)-squared as compared with a complexity of N log N for the Quicksort algorithms. In spite of its worse complexity, Batcher's sorting algorithm is competitive with the serial version of Quicksort for vectors up to the largest that can be treated by STAR. Vector Quicksort outperforms the other two algorithms and is generally preferred. These results indicate that unusual instruction sets can introduce biases in program execution time that counter results predicted by worst-case asymptotic complexity analysis.

  17. Making business sense of the Internet.

    Ghosh, S


    For managers in large, well-established businesses, the Internet is a tough nut to crack. It is very simple to set up a Web presence and very difficult to create a Web-based business model. Established businesses that over decades have carefully built brands and physical distribution relationships risk damaging all they have created when they pursue commerce through the Net. Still, managers can't avoid the impact of electronic commerce on their businesses. They need to understand the opportunities available to them and recognize how their companies may be vulnerable if rivals seize those opportunities first. Broadly speaking, the Internet presents four distinct types of opportunities. First, it links companies directly to customers, suppliers, and other interested parties. Second, it lets companies bypass other players in an industry's value chain. Third, it is a tool for developing and delivering new products and services to new customers. Fourth, it will enable certain companies to dominate the electronic channel of an entire industry or segment, control access to customers, and set business rules. As he elaborates on these four points, the author gives established companies a systematic way to sort through the risks and rewards of doing business in cyberspace. PMID:10177862

  5. An Evaluation of the Critical Factors Affecting the Efficiency of Some Sorting Techniques

    Olabiyisi S.O.


    Full Text Available Sorting allows information or data to be put into a meaningful order. As efficiency is a major concern of computing, data are sorted in order to gain the efficiency in retrieving or searching tasks. The factors affecting the efficiency of shell, Heap, Bubble, Quick and Merge sorting techniques in terms of running time, memory usage and the number of exchanges were investigated. Experiment was conducted for the decision variables generated from algorithms implemented in Java programming and factor analysis by principal components of the obtained experimental data was carried out in order to estimate the contribution of each factor to the success of the sorting algorithms. Further statistical analysis was carried out to generate eigenvalue of the extracted factor and hence, a system of linear equations which was used to estimate the assessment of each factor of the sorting techniques was proposed. The study revealed that the main factor affecting these sorting techniques was time taken to sort. It contributed 97.842%, 97.693%, 89.351%, 98.336% and 90.480% for Bubble sort, Heap sort, Merge sort, Quick sort and Shell sort respectively. The number of swap came second contributing 1.587% for Bubble sort, 2.305% for Heap sort, 10.63% for Merge sort, 1.643% for Quick sort and 9.514% for Shell sort. The memory used was the least of the factors contributing negligible percentage for the five sorting techniques. It contributed 0.571% for Bubble sort, 0.002% for Heap sort, 0.011% for Merge sort, 0.021% for Quick sort and 0.006% for Shell sort.
