Public‐good games and the Balinese

Purpose - The Balinese have been successful for centuries in sustaining cooperation among the members of local communities in order to provide public goods through individual contributions. The purpose of this paper is to review and highlight the Balinese mechanism's remarkable features. Design/methodology/approach - The paper surveyed the experimental literature on public goods and highlighted those features of the Balinese tradition that have been proven to be both effective in the experimental laboratory and successful in deterring free-riding on the field. Findings - The most prominent features discussed are decentralization, democratic decision making, the use of two currencies, supervision, and the possibility of imposing severe sanctions for free-riding. Social implications - The paper's findings not only can help to preserve the high level of cooperation among inhabitants in Bali threatened by migration flows and the increasingly intense reliance on the market mechanism, but they also provide general insights both for theoreticians and practitioners on how to create successful communities. In addition, the literature review sheds light on several features of public-good games that have not been satisfactorily explored yet by experimental economists. Originality/value - The novelty of the paper's approach lies in looking at the Balinese tradition through the glasses of mechanism design theory and aligning the related findings of experimental economics in order to understand its success and problems.
Effect of Different Carbon Sources and Elicitors on Shoot Multiplication in Accessions of Centella asiatica

Centella asiatica is a medicinal herb which has been extensively used in the treatment of nervous disorders and skin diseases. It is distributed throughout the tropical and sub-tropical region of the world. This plant contains various bioactive constituents such as asiaticoside, madecassic acid, flavonoids etc. Centella is in huge demand in International market for the preparation of pharmaceuticals and cosmetics which has resulted in its overexploitation. This situation demands the use of biotechnological methods to conserve as well as increase the production of biomass and bioactive compounds. The present study focused the use of different carbon sources (sucrose and fructose) and elicitors (Malt extract, Salicylic acid and Jasmonic acid) for the enhancement of biomass in five accessions of Centella asiatica. It was concluded that Murashige and Skoog (MS) medium supplemented with 1 mg/L concentration of Malt extract and 1.5 mg/L concentration of 6-Benzyl amino purine (BAP) showed highest biomass production among all elicitors. Among two carbon sources, MS media supplemented with Sucrose (3 mg/L) along with BAP (1.5 mg/L) showed better result than fructose.
Optimization of a DC Capacitor Tank

The choice of a set of capacitors for a dc link may be very different depending on the system requirements and user constraints. This paper shows how to achieve the best choice of a hybrid association of electrolytic capacitor and higher frequency technology (polyester for instance). Maximum allowed rms current in the electrolytic capacitor is obviously taken into account. The input filter of a buck converter is chosen as example. Various constraints are considered: voltage ripple, differential-mode electromagnetic-interference level, losses, weight, volume, surface, etc. Objective function for optimization is defined by the user and may be any of the previous parameters. The optimized result consists in the number and the values of components for both capacitor technologies.
OFDM transceiver design using C

The aim of this paper is to design a baseband orthogonal frequency division multiplexing (OFDM) [1]-[2] transceiver including 8 point Fast Fourier Transform (FFT), 8 point Inverse Fast Fourier Transform (IFFT) [3] core processor, DPSK modulator[4], demodulator serial to parallel and parallel to serial converter blocks in C language. The main challenge is to derive the algorithm for Fast Fourier Transform (FFT) and Inverse Fast Fourier Transform (IFFT). There are many algorithms available that can implement FFT and IFFT.

Unemployment Insurance Fraud and Optimal Monitoring

An important incentive problem for the design of unemployment insurance is the fraudulent collection of unemployment benefits by workers who are gainfully employed. We show how to efficiently use a combination of tax/subsidy and monitoring to prevent such fraud. The optimal policy monitors the unemployed at fixed intervals. Employment tax is nonmonotonic: it increases between verifications but decreases after a verification. Unemployment benefits are relatively flat between verifications but decrease sharply after a verification. Our quantitative analysis suggests that the optimal monitoring cost is 60 percent of the cost in the current US system. (JEL D82, H24, J64, J65)
LVDT Conditioning on the LHC Collimators

The Position Readout and Survey system of the LHC collimators has to monitor in real time (RT), at a frequency close to 100 Hz, the position of the 555 synchronized axes with an accuracy of 20 mum. Radiation hard Linear Variable Differential Transformers (LVDT) are used as absolute position sensors for their ruggedness, intrinsic accuracy and infinite resolution. Because of the radioactive environment the conditioning electronics is located in safe zones up to 800 m away from the sensors. Under these conditions, standard conditioning techniques cannot guarantee the accuracy requested by this application because of cable impedance, noise immunity, crosstalk between signals of different sensors passing within the same multiwire cable and temperature stability. A fully digital approach based on a sine-fit algorithm has been followed and will be described showing the excellent results measured up to now. Particular attention is devoted to the RT implementation of the algorithm on the PXI platform from National Instruments.
THE MYStIX INFRARED-EXCESS SOURCE CATALOG

The Massive Young Star-Forming Complex Study in Infrared and X-rays (MYStIX) project provides a comparative study of 20 Galactic massive star-forming complexes (d = 0.4–3.6 kpc). Probable stellar members in each target complex are identified using X-ray and/or infrared data via two pathways: (1) X-ray detections of young/massive stars with coronal activity/strong winds or (2) infrared excess (IRE) selection of young stellar objects (YSOs) with circumstellar disks and/or protostellar envelopes. We present the methodology for the second pathway using Spitzer/IRAC, 2MASS, and UKIRT imaging and photometry. Although IRE selection of YSOs is well-trodden territory, MYStIX presents unique challenges. The target complexes range from relatively nearby clouds in uncrowded fields located toward the outer Galaxy (e.g., NGC 2264, the Flame Nebula) to more distant, massive complexes situated along complicated, inner Galaxy sightlines (e.g., NGC 6357, M17). We combine IR spectral energy distribution (SED) fitting with IR color cuts and spatial clustering analysis to identify IRE sources and isolate probable YSO members in each MYStIX target field from the myriad types of contaminating sources that can resemble YSOs: extragalactic sources, evolved stars, nebular knots, and even unassociated foreground/background YSOs. Applying our methodology consistently across 18 of the target complexes, we produce the MYStIX IRE Source (MIRES) Catalog comprising 20,719 sources, including 8686 probable stellar members of the MYStIX target complexes. We also classify the SEDs of 9365 IR counterparts to MYStIX X-ray sources to assist the first pathway, the identification of X-ray-detected stellar members. The MIRES Catalog provides a foundation for follow-up studies of diverse phenomena related to massive star cluster formation, including protostellar outflows, circumstellar disks, and sequential star formation triggered by massive star feedback processes.
Fast Coupled Retransmission for Multipath TCP in Data Center Networks

We study an energy efficiency (EE)-optimized power allocation technique for a source and a relay in a cooperative cognitive radio network. We formulate the optimization problem with the constraint on probabilistic interference parameters and throughput as a fractional programming problem. The problem is quasi-convex, for which a local optimal solution may not be guaranteed as a global optimal solution. Hence, we transform the problem into an equivalent convex programming problem using the Charnes–Cooper transformation technique to obtain an optimal solution. We analyze the channel access probability, EE, and total power performance of the cooperative cognitive green radio network via simulation.
PREDICTIVE INVERSE NEUROCONTROL AND CONVENTIONAL MODEL PREDICTIVE CONTROL: COMPARATIVE SIMULATION AND EXPERIMENT

The paper compares the traditional model predictive control (MPC) with the proposed predictive inverse neurocontrol (PIN) technique. The PIN approach allows to avoid the online optimization procedure and thus sufficiently reduces the need for computing power and becomes especially important for the control of the plants with fast dynamics. Results of model and physical experiments are shown.
Cluster Analysis as a Tool for Characterizing Water Reclamation Plant Influent

Water reclamation plants (WRP) face the challenging task of simultaneously managing fluctuating influent conditions and satisfying effluent discharge requirements. To better prepare WRP operators for this task, we combined k-means cluster analysis with cross-tabulation analysis to develop an influent classification system for the Calumet WRP in Chicago, IL. We considered weather and influent composition characteristics to identify 25 clusters, nine of which were significant (99% confidence level). For example, dry weather with mid-range temperature characteristics are common after wet weather days, and these conditions typically present low influent concentrations. In addition, compared to cold-weather characteristics, warm-weather flows are more likely to have large precipitation events and more variation in influent quality. The duration of storm events is also important for planning. Large storms during warm weather feature relatively low influent concentrations and have a high probability of lasting only one day, whereas warm and dry-weather conditions that bring relatively high influent concentrations have a high probability of lasting more than one day. We believe the approach used in this study can be replicated and will provide useful risk management information at other WRPs.
Know-How Transfer of Public Support Programs for Small and Medium-Sized Enterprises from Slovenia to the Former Yugoslav Republic of Macedonia

The need for external business support for small and medium enterprises has been an issue for many governments around the world. Government agencies have developed several initiatives and the scheme presented in this paper is targeted at support in the form of counselling, combined with provision of information and training to small and medium-sized enterprises. The program was started in Slovenia in 2000 and in 2006 the know-how for the system was transferred to the Former Yugoslav Republic of Macedonia. After the pilot phase, the need for its assessment evolved. An opportunity also for the transfer of methodology for its evaluation came clear. Thus, the same approach was used in both countries, which enabled an excellent benchmarking opportunity for further development of the scheme in the two countries. This paper presents the fundamental concept of the voucher system. The assumptions for an effective system are analyzed and comments from evaluations are discussed. The potential for further development of the system in the Former Yugoslav Republic of Macedonia is discussed.
Advanced Testing and Modeling of Magnetic Materials Including a New Method of Core Loss Separation for Electrical Machines

This paper presents a new method for the separation of core loss components (hysteresis and eddy current) in laminations exposed to high-frequency excitations. Accurate separation of core losses is achieved by calculating the hysteresis losses at each frequency taking into account the nonuniform flux distribution inside the lamination. The results highlight that the assumption of constant hysteresis energy loss per cycle is only valid at low frequencies, where skin effect is negligible. The developed model is then used to study the effect of the annealing process on core loss components in laminations exposed to high-frequency excitations. Core loss measurements are performed on different laminations at several frequencies in the range of 20-4000 Hz. A comparison of the separated core loss components shows that a huge reduction in the hysteresis losses is achieved by annealing, while the annealing process increases the eddy-current loss component at high frequencies and high flux densities. The results are then analyzed by comparing the separated eddy-current loss with an analytical eddy-current loss model that accounts for the nonuniform distribution of the magnetic field.
Sustainability practices and web-based communication: An analysis of the Italian fashion industry

Purpose – The purpose of this paper is to examine which environmental and social sustainability practices companies in the Italian fashion industry adopt and how these companies communicate their sustainability commitment through their corporate websites. Design/methodology/approach – The multiple case studies approach was selected and the practices of 12 companies in the Italian fashion industry were investigated. Findings – The findings showed that four different approaches in the field of sustainability practices and web-based communication are available within the Italian fashion industry (i.e. low commitment, high commitment, low disclosure, high marketing) by highlighting the alignment (i.e. fit or misfit) among these dimensions and by discussing the practices as well as the drivers/barriers of each approach. Originality/value – The paper contributes to the literature by deepening the understanding of both the environmental and social dimensions of the sustainability issue. Moreover, the work invest.
Optimal transmit strategy for MIMO channels with joint sum and per-antenna power constraints

This paper studies optimal transmit strategies for multiple-input multiple-output (MIMO) Gaussian channels with joint sum and per-antenna power constraints. It is shown that if an unconstraint optimal allocation for an antenna exceeds a per-antenna power constraint, then the maximal power for this antenna is used in the constraint optimal transmit strategy. This observation is then used in an iterative algorithm to compute the optimal transmit strategy in closed-form. Finally, a numerical example is provided to illustrate the theoretical results.
The NEMO floor control module

An electronic board, called floor control module (FCM), was developed for NEMO project, an underwater neutrino telescope. The offshore FCM is in charge of providing interfaces toward instrumental control boards, collecting data from up to 8 readout electronics, packing and sending streams to the onshore laboratory through an optical fiber driven by a DWDM electro-optical transceiver. To obtain a common timing at each level of the apparatus, communication adopts an SDH protocol, a standard telecommunication synchronous format which allows clock recovery from bitstream, thus simplifying the distribution network. The channel is fully bidirectional to allow underwater apparatus control. The same FCM, plugged into a PCI bus, can also be used onshore for data reception and transmission, providing a complete real-time data transport architecture between the onshore laboratory and the underwater electronics
Rapid creation of BAC-based human artificial chromosome vectors by transposition with synthetic alpha-satellite arrays

Efficient construction of BAC-based human artificial chromosomes (HACs) requires optimization of each key functional unit as well as development of techniques for the rapid and reliable manipulation of high-molecular weight BAC vectors. Here, we have created synthetic chromosome 17-derived alpha-satellite arrays, based on the 16-monomer repeat length typical of natural D17Z1 arrays, in which the consensus CENP-B box elements are either completely absent (0/16 monomers) or increased in density (16/16 monomers) compared to D17Z1 alpha-satellite (5/16 monomers). Using these vectors, we show that the presence of CENP-B box elements is a requirement for efficient de novo centromere formation and that increasing the density of CENP-B box elements may enhance the efficiency of de novo centromere formation. Furthermore, we have developed a novel, high-throughput methodology that permits the rapid conversion of any genomic BAC target into a HAC vector by transposon-mediated modification with synthetic alpha-satellite arrays and other key functional units. Taken together, these approaches offer the potential to significantly advance the utility of BAC-based HACs for functional annotation of the genome and for applications in gene transfer.
A 3D packaging technology for acoustically optimized integration of 2D CMUT arrays and front end circuits

As compared to piezoelectric technology, MEMS technology employed for Capacitive Micromachined Ultrasonic Transducer (CMUT) fabrication provides increased compatibility with 3D packaging methods, enabling the possible development of advanced transducer-electronics multi-chip modules (MCM) for medical imaging applications. Interconnection of 2D CMUT arrays and analog front end integrated circuits (IC) using die-level packaging methods was demonstrated earlier. However, no effort was devoted to the study and optimization of the acoustic behavior of the resulting MCM. In this paper, we propose an acoustically optimized 3D packaging method for the interconnection of Reverse-Fabricated CMUT [doi: 10.1088/0960-1317/25/1/015012] 2D arrays and front end ICs using a wafer-level compatible process.
Scalability of surface PM machines with concentrated windings designed to achieve wide speed ranges of constant-power operation

Previous work has shown that it is possible to design surface permanent magnet (SPM) synchronous machines using fractional-slot concentrated windings to achieve wide speed ranges of constant-power operation. A closed-form analytical technique is now available to rapidly analyze candidate SPM machine designs using concentrated windings and tune them to meet the critical condition for optimal flux weakening. This analytical tool is used to demonstrate that optimal flux weakening can be achieved in SPM machines that are varied over wide ranges in several key dimensions including machine pole numbers, diameter-to-length aspect ratios, and output power ratings. Performance requirements for a 6 kW direct-drive automotive starter/alternator machine are used as the starting point for the scalability investigation. Finite element analysis results are presented to confirm the validity of key results
Optimization of Open Midplane Dipole Design for LHC IR Upgrade

This paper presents the optimized designs of an “open midplane dipole” [1] for “dipole first optics” [2] for the proposed luminosity upgrade of the Large Hadron Collider (LHC). It was found [3] that in this design at luminosity of 1035cm-2s-1, the peak power density in the coils can be up to two orders of magnitude higher than that at the present baseline luminosity (1034cm-2s-1). This comes from a large quantity of spray particles from Interaction Point (IP) that is mostly concentrated at the midplane. The “open midplane dipole” design is the only design so far that has been found to provide reliable quench-stable operation with a lifetime of the critical components of at least ten years. In addition to a summary of magnetic, mechanical and energy deposition calculations for various iterations, the inherent benefits and challenges associated with the “open midplane dipole” design are also discussed. Results are presented for a recently proposed attractive option with the dipole splitted in two with a warm absorber placed between the two [4].
Document Categorization Using BayesTH-MCRDR Algorithm : Empirical Analysis and Comparison with Other Document Classification Methods

The research suggests the BayesTH-MCRDR algorithm for effective classification of E-mail documents. This is a compound algorithm which combines a naïve Bayesian algorithm using Threshold and the MCRDR (Multiple Classification Ripple Down Rules) algorithm. The significant feature of document classification using the BayesTH-MCRDR algorithm is the achievement of higher precision by first establishing a knowledge base of optimally related words generated from the document training set before going on to classify the set of test documents. Further, we demonstrate the system we have developed in order to compare a number of classification techniques.
Low relatedness among cooperatively breeding workers of the greenhead ant Rhytidoponera metallica

The greenhead ant Rhytidoponera metallica has long been recognized as posing a potential challenge to kin selection theory, because it has large queenless colonies where apparently many of the morphological workers are mated and reproducing. However, this species has never been studied genetically and important elements of its breeding system and kin structure remain uncertain. We used microsatellite markers to measure the relatedness among nestmates, unravel the fine‐scale population genetic structure, and infer the breeding system of R. metallica. The genetic relatedness among worker nestmates is very low but significantly greater than zero (r=0.082 ± 0.015), which demonstrates that nests contain many distantly related breeders. The inbreeding coefficient is very close to and not significantly different from zero, indicating random mating and lack of microgeographic genetic differentiation. On average, closely located nests are not more similar genetically than distant nests, which is surprising, as new colonies form by budding and female dispersal is restricted. Lack of inbreeding and absence of population viscosity indicates high gene flow mediated by males. Overall, the genetic pattern detected in R. metallica suggests that a high number of moderately related workers mate with unrelated males from distant nests. This breeding system results in the lowest relatedness among nestmates reported for social insect species where breeders and helpers are not morphologically differentiated.
