    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available We propose a novel twelve-channel Dense Wavelength Division Multiplexing (DWDM demultiplexer, using the two-dimensional photonic crystal (2D PC with square resonant cavity (SRC of ITU-T G.694.1 standard. The DWDM demultiplexer consists of an input waveguide, SRC, and output waveguide. The SRC in the proposed demultiplexer consists of square resonator and microcavity. The microcavity center rod radius (Rm is proportional to refractive index. The refractive index property of the rods filters the wavelengths of odd and even channels. The proposed microcavity can filter twelve ITU-T G.694.1 standard wavelengths with 0.2 nm/25 GHz channel spacing between the wavelengths. From the simulation, we optimize the rod radius and wavelength with linear regression analysis. From the regression analysis, we can achieve 95% of accuracy with an average quality factor of 7890, the uniform spectral line-width of 0.2 nm, the transmission efficiency of 90%, crosstalk of −42 dB, and footprint of about 784 μm2.

  17. Manufacturing of lasers for DWDM systems

    1999-11-01

    The evolution of dense wavelength division multiplexing (DWDM) has allowed service provides a convenient and cost effective method to dramatically increase transmission capacity over existing and new fiber network systems. As the demand for bandwidth continues to increase, systems designers are responding by increasing both the number of channels and the data rates. This trend has placed considerable pressure on many of the underlying system components. One component that has been particularly challenged by this trend is the manufacture of semiconductor lasers. This paper reviews the technical and logistical challenges faced in the high volume manufacture of lasers to support DWDM systems. As the product portfolio continues to expand, precise execution and team work among multiple organizations is required to assure reliable shipping performance. Production scheduling and manufacturing operations must work closely to continuously re-prioritize the work in process in response to constantly changing channel demand and yield fluctuations. Wavelength prediction models must be developed that correlate in-process parameters to final device wavelength. These models are then applied to both in-process specification targeting and inventory management. Once the in-process specifications are properly targeted, the challenge moves to the fabrication processes, where processes are pushed to the limits of their control. Underpinning the entire effort must be an information management system in which parametric data is collected, wavelength prediction models are executed, and work in process inventory is controlled with respect to the final output volume and wavelength distribution.

    2001-10-01

    The new definition and implementation of new communication network architectures and elements in the present data-centric world are due to dramatic change in technology, explosive growth in bandwidth requirement and de-regulated, privatized and competitive telecommunication market. Network Convergence, Disruptive Technology and Convulsive Market are the basic forces who are pushing the future network towards Packet based Optical Core Network and varieties of Access Network along with integrated NMS. Well-known Moore's law governs the result of progress in silicon processing and accordingly the present capacity of network must be multiplied by 100 times in 10 years. To build a global network which is 100 times powerful than present one by scaling up today's technology can not be a practical solution due to requirement of 100 fold increase in cost, power and size. Today's two network (Low delay, fixed bandwidth, Poisson voice traffic based, circuit-switched PSTN/PLMN and variable delay, variable bandwidth, no-guaranteed QoS based packet switched internet) are converging towards two-layer network (IP and ATM in lower layer; DWDM in network layer). SDH Network which was well drafted before explosive data traffic and was best suitable for Interoperability, Survivability, Reliability and Manageability will be taken over by DWDM Network by 2005 due to 90% of data traffic. This paper describes the way to build the Communication Network (either by migration or by overlay) with an overview of the equipment and technologies required to design the DWDM Network. Service Providers are facing tough challenges for selection of emerging technologies and advances in network standard for bandwidth hungry, valued customers. The reduction of cost of services due to increased competition , explosive growth of internet and 10GbE Ethernet (which is being considered as an end-to-end network solution) have given surprise to many network architects and designers.

The correspondence of this amplitude noise with the crosstalk spectral distribution is evaluated theoretically and experimentally.

  12. Wavelength-Agile External-Cavity Diode Laser for DWDM

    Science.gov (United States)

    Pilgrim, Jeffrey S.; Bomse, David S.

    2006-01-01

    A prototype external-cavity diode laser (ECDL) has been developed for communication systems utilizing dense wavelength- division multiplexing (DWDM). This ECDL is an updated version of the ECDL reported in Wavelength-Agile External- Cavity Diode Laser (LEW-17090), NASA Tech Briefs, Vol. 25, No. 11 (November 2001), page 14a. To recapitulate: The wavelength-agile ECDL combines the stability of an external-cavity laser with the wavelength agility of a diode laser. Wavelength is modulated by modulating the injection current of the diode-laser gain element. The external cavity is a Littman-Metcalf resonator, in which the zeroth-order output from a diffraction grating is used as the laser output and the first-order-diffracted light is retro-reflected by a cavity feedback mirror, which establishes one end of the resonator. The other end of the resonator is the output surface of a Fabry-Perot resonator that constitutes the diode-laser gain element. Wavelength is selected by choosing the angle of the diffracted return beam, as determined by position of the feedback mirror. The present wavelength-agile ECDL is distinguished by design details that enable coverage of all 60 channels, separated by 100-GHz frequency intervals, that are specified in DWDM standards.

  13. The suitability of SiGe multiple quantum well modulators for short reach DWDM optical interconnects.

    Science.gov (United States)

    Kekatpure, Rohan D; Lentine, Anthony

    2013-03-11

    We describe calculations that address the suitability at using silicon-germanium multiple quantum well (MQW) modulators in dense wavelength division multiplexed (DWDM) short reach optical interconnects that vary over a significant temperature range. Our calculations indicate that there is a tradeoff between the number of channels, the temperature range and laser power required. Twenty to forty DWDM channels at 100 GHz and 50 GHz channel spacing is possible in DWDM links with a ~ 12° temperature range with less than a 1 dB laser power penalty compared to the optimum single channel, single temperature case. The same number of channels can be operated over a wider 37° temperature range with laser power penalties of 3 dB. It shows that, even for DWDM systems, silicon-germanium modulators might provide an alternative to ring and disk resonant modulators without the need for stringent (< 1 °C) temperature control.

    Dense wavelength division multiplexing (DWDM) has been widely applied in ground optical communication. However, the technology of DWDM is still not mature enough in the space optical communication system. In order to further advance the use of DWDM into space optical communication, the probability density function (PDF) and the bit-error rate (BER) performance of DWDM is investigated in uplink communications under the influence of atmospheric turbulence, consisting of intensity scintillation and beam wander caused by atmospheric turbulence. Numerical results show that the atmospheric turbulence has a great impact on BER and PDF, and wavelength, divergence angel, and other relevant parameters should be carefully considered in this DWDM system. This work can be conducive for improving DWDM design of space optical uplink communication systems.

    Directory of Open Access Journals (Sweden)

    Eduardo Canale

    2014-04-01

    Full Text Available Different approaches for deploying resilient optical networks of low cost constitute a traditional group of NP-Hard problems that have been widely studied. Most of them are based on the construction of low cost networks that fulfill connectivity constraints. However, recent trends to virtualize optical networks over the legacy fiber infrastructure, modified the nature of network design problems and turned inappropriate many of these models and algorithms. In this paper we study a design problem arising from the deployment of an IP/MPLS network over an existing DWDM infrastructure. Besides cost and resiliency, this problem integrates traffic and capacity constraints. We present: an integer programming formulation for the problem, theoretical results, and describe how several metaheuristics were applied in order to find good quality solutions, for a real application case of a telecommunications company.

    Full Text Available In this paper a 16-bit differential phase shift keying (DPSK modulator is designed for 32 dense wavelength division multiplexing (DWDM channels. The DWDM channels are designed with 0.8nm separation in wavelength and operated at 4dBm input power. In the DWDM system, these 32 multiplexed signals propagate through a fiber length of 100 km followed by an erbium-doped fiber amplifier (EDFA inline. The channel is equipped with pre-amplifier and a dispersion compensating fiber for better performance. Also, a threshold detector is designed for both in-phase and quadrature components to detect the input amplitude and provide a quantized output amplitude level. The result shows that, a 16-bit DPSK optical signal is demodulated successfully using direct detection receiver.

    We propose and demonstrate a 10-Gb/s dense wavelength-division-multiplexing (DWDM) optical system based on a pulsed-seed-light source employing a fiber-based Mach-Zehnder interferometer (F-MZI) as an intensity noise suppressor. The transmission results show that the required injection power into a reflective modulator was as low as -18 dBm. The F-MZI can accommodate the polarized seed-light with superior noise characteristics so that the supported DWDM systems double using a single conventional unpolarized seed-light. In addition, an allowable length of the drop fiber is investigated to show the system flexibility.

    The compression of 200GHz DWDM channelized optically mode-locking WRC-FPLD fiber ring pulse of at 10 GHz is performed for high-capacity TDM application. To prevent temporal and spectral cross-talk, the duty-cycle of the DWDM channelized WRC-FPLD FL pulse needs to be shortened without broadening its linewidth. With dual-cavity configuration induced DWDM channelization, a shortest single-channel WRC-FPLD FL pulsewidth of 19 ps is generated, which can be linearly compensated to 10 ps and fifth-order soliton compressed to 1.4 ps. Under a maximum pulsewidth compression ratio up to 14 and a +/-100 m tolerance on compressing fiber length, the single-channel pulsewidth remains DWDM channelized WRC-FPLD FL pulsed carrier is approaching 1% to satisfy at least 256 optical TDM channels.

    A. Markovic

    2013-04-01

    Full Text Available This paper provides an analysis of the multiplexed video signal transmission through the Dense Wavelength Division Multiplexing (DWDM network based on a quality check algorithm, which determines where the interruption of the transmission quality starts. On the basis of this algorithm, simulations of transmission for specific values of fiber parameters ​​ are executed. The analysis of the results shows how the BER and Q-factor change depends on the length of the fiber, i.e. on the number of amplifiers, and what kind of an effect the number of multiplexed channels and the flow rate per channel have on a transmited signals. Analysis of DWDM systems is performed in the software package OptiSystem 7.0, which is designed for systems with flow rates of 2.5 Gb/s and 10 Gb/s per channel.

    2011-02-01

    A novel approach is proposed to design super narrowband DWDM Filters consisting of multiple quantum wells (MQWs) by employing photonic crystals. Numerical investigations prove that the closed-cavity MQWs are more suitable for DWDM systems compared with the open-cavity MQWs. It is shown that different confined states could emerge from photonic band gap, which can be used as high-frequency carriers one-to-one. It is also found that these proposed MQWs could split the single spectral lines into multiples based on the effect of spectral splitting, and the number of the splitting is just equal to the number of the wells. In this way, the density of carriers can be increased multiplicatively in the same wave band, and thus the spectral efficiency can be improved multiplicatively. These results provide the prospects of channel density maximization and effective bandwidth optimization for optical communication.

    2015-09-01

    The formal solution for the couple equations of the stimulated Raman scattering (SRS) with different loss coefficients in the DWDM transmission system was discussed. The variation of each signal photon flux along the transmission distance is shown clearly by the formal solution. Then, the analytical solution is obtained from the formal solution when the loss coefficient is the same. Simultaneously, the analytical solution of the small-signal model is derived, too. We also proposed a novel algorithm according to the formal solution, and verified its correctness by showing that the curves for them are basically in coincidence. The result has a certain significance for study on DWDM transmission system and Raman fiber amplifier.

    2007-10-17

    Design and fabrication of a tunable gain equalization filter for dense wavelength division multiplexed (DWDM) signals through erbium doped fiber amplifiers (EDFA) is reported. It is based on a side-polished fiber (SPF) half-coupler block loaded with a displaceable tapered multimode overlay waveguide (MMOW). A simple and accurate normal mode analysis is employed to design this filtering device for its subsequent realization. Equalization of a typical EDFA gain spectrum in the C-band within +/-0.35 dB or even less in the presence of various ITU standard C-band DWDM signal channels is demonstrated under varied operating conditions like add/drop of signals. Tunability of the filter notch is achieved through displacement of the SPF relative to the MMOW.

    We demonstrate a 25 GHz-channel-spaced DWDM-PON based on ASE injection seeding. A 60 km transmission at 1.25 Gb/s per channel is available with a 2nd generation FEC. The major limiting factor is the optical back reflection induced penalty. Thus a high gain reflective modulator and/or relocation of the seed light increase the transmission length. We demonstrated 90 km transmission with relocated seed light to remote node.

    Full Text Available Free Space Optical (FSO communication is being realized as an effective solution for future accessing networks, offering light passed through air. The performance of FSO can be primarily degraded by various atmospheric attenuation namely, rain, fog, haze and snow. At present, hybridization of Dense Wavelength Division Multiplexing (DWDM with Coarse Wavelength Division Multiplexing (CWDM becomes necessary to scale the speed and high bandwidth of the services. In this paper, hybrid WDM system is proposed, designed and the network parameters such as Bit Error Rate (BER, Quality Factor and receiver sensitivity are analyzed with respect to link distance for various weather conditions. For investigation, 4 CWDM and 8 DWDM channels are considered whose corresponding channel spacing is 20nm and 0.8nm, respectively. From the simulation, it is investigated that the average link distance of proposed hybrid WDM-FSO system for DWDM and CWDM system at very clear condition are around 810km and 780km. The proposed hybrid WDM based FSO system is designed to handle the quality of transmission for 12 users, each at a data rate of 2.5Gbps.

    Full Text Available Traditional budgeting principles, with strictly defined business goals, have been, since 1998, slowly growing into more sophisticated and organization-adjusted alternative budgeting concepts. One of those alternative concepts is the “Beyond budgeting” model with an implemented performance effects measuring process. In order for the model to be practicable, budget planning and control has to be reoriented to the “bottom up” planning and control approach. In today’s modern business surroundings one has to take both present and future opportunities and threats into consideration, by valorizing them in a budget which would allow a company to realize a whole pallet of advantages over the traditional budgeting principles which are presented later in the article. It is essential to emphasize the importance of successfully implementing the new budgeting principles within an organization. If the implementation has been lacking and done without a higher goal in mind, it is easily possible that the process has been implemented without coordination, planning and control framework within the organization itself. Further in the article we present an overview of managerial techniques and instruments within the “Beyond budgeting” model such as balanced scorecard, rolling forecast, dashboard, KPI and other supporting instruments. Lastly we define seven steps for implementing the “Beyond budgeting” model and offer a comparison of “Beyond budgeting” model against traditional budgeting principles which lists twelve reasons why “Beyond budgeting” is better suited to modern and market-oriented organizations. Each company faces those challenges in their own characteristic way but implementing new dynamic planning models will soon become essential for surviving in the market.

    2007-10-01

    Aside from the more traditional data, voice and e-mail communications, new bandwidth intensive applications in the larger consumer markets, such as music, digital pictures and movies, have led to an explosive increase in the demand for transmission capacity for optical communications networks. This has resulted in a widespread deployment of Dense Wavelength Division Multiplexing (DWDM) as a means of increasing the communications capacity by multiplexing and transmitting signals of different wavelengths (establishing multiple communication channels) through a single strand of fiber. We report on the design, assembly and characterization of a 50-GHz, 80-channel Mux-Demux module for DWDM systems. The module has been assembled from two commercially available 100 GHz, 40-channel Array Waveguide Grating (AWG) modules and a 50-GHz to 100-GHz interleaver. Relevant performance parameters such as insertion loss, channel uniformity, next-channel isolation (crosstalk) and integrated cross-talk are presented and discussed in contrast with the performance of other competing technologies such as Thin-Film-Filter-based Mux-Demux devices.

  15. Distributed Grooming in Multi-Domain IP/MPLS-DWDM Networks

    Energy Technology Data Exchange (ETDEWEB)

    Liu, Qing [ORNL

    2009-12-01

    This paper studies distributed multi-domain, multilayer provisioning (grooming) in IP/MPLS-DWDM networks. Although many multi-domain studies have emerged over the years, these have primarily considered 'homogeneous' network layers. Meanwhile, most grooming studies have assumed idealized settings with 'global' link state across all layers. Hence there is a critical need to develop practical distributed grooming schemes for real-world networks consisting of multiple domains and technology layers. Along these lines, a detailed hierarchical framework is proposed to implement inter-layer routing, distributed grooming, and setup signaling. The performance of this solution is analyzed in detail using simulation studies and future work directions are also high-lighted.

    2017-05-01

    There has been increasing demand for connection setup with a higher quality of service (QoS) in WDM/DWDM networks, especially in fields like radio over fiber, where phase modulation affects the link quality. Hence to meet guaranteed QoS in a phase modulated link, the effects of phase modulation on link quality are very much needed. The link quality is termed as quality factor (Q-factor). The primary objective is to use effectively the connections available to optimize the computed number of connections and reduce the blocked connections but at the same time guaranteeing QoS as per client's need. The analysis has been done by taking care of routing and wavelength assignment (RWA) techniques. The performance analysis is presented in terms of blocking probability.

The research results illustrate that our modified scheme can improve the dispersion of more than 76.6% in comparison with the previous studies of optical interleaver with birefringent crystal and ring cavity structures.

    In this paper, we propose a narrowband DWDM filter structure, whose reflection band characteristics, meets the ITU-T standard. The proposed filter structure is based on Fibonacci quasi-periodic structures composed of multilayers with large index differences. Studying the effects of the optical and geometrical parameters of Fibonacci quasi-periodic structures on its filtering properties, we have realized that to achieve the ITU-T standard, we need to cascade two successive structures both with the same generation numbers j=4 and orders n=25 and apodized refractive indices. The apodization process helps to minimize the stop band sidelobes. We have also demonstrated that beside Fibonacci's order, n, the layers dimensions, and their refractive index ratios are the main design parameters.

    We present the synthesis of multi-channel fiber Bragg grating (MCFBG) filters for dense wavelength-division-multiplexing (DWDM) application by using a simple optimization approach based on a Lagrange multiplier optimization (LMO) method. We demonstrate for the first time that the LMO method can be used to constrain various parameters of the designed MCFBG filters for practical application demands and fabrication requirements. The designed filters have a number of merits, i.e., flat-top and low dispersion spectral response as well as single stage. Above all, the maximum amplitude of the index modulation profiles of the designed MCFBGs can be substantially reduced under the applied constrained condition. The simulation results demonstrate that the LMO algorithm can provide a potential alternative for complex fiber grating filter design problems.

    The differential phase Q value method is adopted to investigate carried-suppressed return-to-zero (CSRZ), return-to-zero differential phase shift keying (RZ-DPSK), and optical duobinary (ODB) codes in 32 × 40 Gb/s DWDM system. The relationship between the transmission distance and optical output power is compared in order to select the optimal code. Furthermore, mixed phase noise of the spontaneous emission noise (ASE), Gordon-Mollenauer (GM) noise, and intrachannel four wave mixing (IFWM) effect has been analyzed. The numerical results show that DPSK is the most suitable for the DWDM system and adjustable range of output optical power is up to 10.2 dBm at 1200 km. Besides, ASE noise is dominant in degradation of received signal quality. However, RZ-DPSK and CSRZ show better performance for suppression of ASE noise, which can serve as a guideline for upgrading in current state-of-art deployed system.

    A modified selective area growth (SAG) technique, in which the effective index of only the upper separate confinement heterostructure (SCH) layer are modulated to obtain different emission wavelengths, is reported for the fabrication of dense wavelength division multiplexing (DWDM) multi-wavelength laser arrays (MWLAs). InP based 1.5 μm distributed feedback (DFB) laser arrays with 0.8 nm, 0.42 nm, and 0.19 nm channel separations are demonstrated, all showing highly uniform wavelength spacings. The standard deviation of the distribution of the wavelength residues with respect to the corresponding linear fitting values is 0.0672 nm, which is a lot smaller than those of the MWLAs fabricated by other techniques including electron beam lithography. These results indicate that our SAG technique which needs only a simple procedure is promising for the fabrication of low cost DWDM MWLAs.

    We propose the experimental transport of 48 channels with 40 Gbit/s dense wavelength-division multiplexing (DWDM) system that uses single-mode fiber (SMF) in combination with dispersion compensation fiber (DCF) which is a dispersion compensation device, in C and L band wavelength range to solve the dispersion program. The DWDM system scheme employing single Mach-Zehnder modulation (MZM) return-to-zero differential phase-shift keying (RZ-DPSK) modulation format with hybrid Raman/EDFA (Erbium-doped fiber amplifier) configuration to improve transmission signal, and employing an optical phase conjugation (OPC) configuration in the middle line. That can compensate for dispersion impairment and improve nonlinear effects to investigate transmission distance performances.

    Dense wavelength division multiplexed (DWDM) transmission equal to 1.2 Tbps over 25 to 50 km across standard single-mode fiber (SSMF) in the C band is performed based on an optical frequency comb generator. Sixty-one flattened optical frequency tones were realized with 30-GHz frequency spacing, high side-mode suppression ratio over 35 dB, and minimum amplitude difference was realized using amplitude modulator for first time in cascade mode with two Mach-Zehnder modulators (MZMs) where all the modulators were tailored by RF signals. 20×61 Gbps DWDM-based differential quadrature phase shift keying modulated signals were successfully transmitted over SSMF and analyze its transmission capability for range of 25 to 50 km with acceptable power penalties and bit error rates.

    We proposed and experimentally demonstrated a novel radio-over-fiber architecture using an electrical mixer and an optical intensity modulator based on double side-band modulation scheme to generate dense wavelength-division multiplexing (DWDM) optical millimeter for carrying downstream data and centralized lightwave for carrying upstream data. Since the remaining optical carriers with high power have been reused, the optical power is effectively utilized; therefore the system cost can be reduced.

    2017-08-01

    Higher spectral efficiency and greater data rate per channel are the most cost-effective strategies to meet the exponential demand of data traffic in the optical core network. Multilevel modulation formats being spectrally efficient enhance the transmission capacity by coding information in the amplitude, phase, polarization or a combination of all. This paper presents the design architecture of a 32-channel dense wavelength division multiplexed (DWDM) system, where each channel operates with multi-level phase modulation formats at 40 Gbps. The proposed design has been simulated for 50 GHz channel spacing to numerically compute the performance of both differential phase-shift keying (DPSK) and differential quadrature phase-shift keying (DQPSK) modulation formats in such high-speed DWDM system. The transmission link is analyzed with perfect dispersion compensation and also with under-compensation scheme. The link performance in terms of quality factor (Q) for varying input powers with different dispersion compensation schemes has been evaluated. The simulation study shows significant nonlinear mitigation for both DPSK- and DQPSK-based DWDM systems up to 1,000 km and beyond. It is concluded that at higher power levels DQPSK format having a narrower spectrum shows better tolerance to dispersion and nonlinearities than DPSK format.

  10. Development of Low Noise-Broadband Raman Amplification Systems Based on Photonic Crystal Fibers for High Capacity DWDM Networks

    Science.gov (United States)

    Elgamri, Abdelghafor

    The increased demand from IP traffic, video application and cell backhaul has placed fiber routes under severe stains. The high demands for large bandwidth from enormous numbers from cell sites on a network made the capacity of yesterday's networks not adequate for today's bandwidth demand. Carries considered Dense Wavelength Division Multiplexing (DWDM) network to overcome this issue. Recently, there has been growing interest in fiber Raman amplifiers due to their capability to upgrade the wavelength-division-multiplexing bandwidth, arbitrary gain bandwidth. In addition, photonic crystal fibers have been widely modeled, studied, and fabricated due to their peculiar properties that cannot be achieved with conventional fibers. The focus of this thesis is to develop a low-noise broadband Raman amplification system based on photonic crystal Fiber that can be implemented in high capacity DWDM network successfully. The design a module of photonic crystal fiber Raman amplifier is based on the knowledge of the fiber cross-sectional characteristics i.e. the geometric parameters and the Germania concentration in the dope area. The module allows to study different air-hole dimension and disposition, with or without a central doped area. In addition the design integrates distributed Raman amplifier and nonlinear optical loop mirror to improve the signal to noise ratio and overall gain in large capacity DWDM networks.

    2008-04-01

    The Critical dimension off-target (CDO) is a key parameter for mask house customer, affecting directly the performance of the mask. The CDO is the difference between the feature size target and the measured feature size. The change of CD during the process is either compensated within the process or by data correction. These compensation methods are commonly called process bias and data bias, respectively. The difference between data bias and process bias in manufacturing results in systematic CDO error, however, this systematic error does not take into account the instability of the process bias. This instability is a result of minor variations - instabilities of manufacturing processes and changes in materials and/or logistics. Using several masks the CDO of the manufacturing line can be estimated. For systematic investigation of the unit process contribution to CDO and analysis of the factors influencing the CDO contributors, a solid understanding of each unit process and huge number of masks is necessary. Rough identification of contributing processes and splitting of the final CDO variation between processes can be done with approx. 50 masks with identical design, material and process. Such amount of data allows us to identify the main contributors and estimate the effect of them by means of Analysis of variance (ANOVA) combined with multivariate analysis. The analysis does not provide information about the root cause of the variation within the particular unit process, however, it provides a good estimate of the impact of the process on the stability of the manufacturing line. Additionally this analysis can be used to identify possible interaction between processes, which cannot be investigated if only single processes are considered. Goal of this work is to evaluate limits for CDO budgeting models given by the precision and the number of measurements as well as partitioning the variation within the manufacturing process. The CDO variation splits according to

    This paper reflects the analytical study of dense wavelength division multiplexed optical network with different number of channels at various channel spacing in order to achieve higher data rates by means of few advanced modulation schemes. Bit error rate and quality factor are being analyzed with the variation in number of channels, channel spacing and transmission length of fiber. Advanced modulation schemes being compared here are carrier suppressed return to zero (CSRZ), duobinary return to zero (DRZ), modified duobinary return to zero (MDRZ), 33 % differential phase shift keying (33 % DPSK), 66 % DPSK and differential quaternary phase shift keying (DQPSK). It is keenly observed that CSRZ scheme with 100 GHz channel spacing serves best performance in terms of max. Q factor, min. BER and maximum transmission coverage upto 4,000 km for 16 and 32 channels DWDM system since CSRZ is high tolerant to nonlinear effects. On the other hand, MDRZ scheme with 75 GHz channel spacing exhibits transmission coverage upto 4,000 km and 4,500 km for 16 and 32 channels respectively, but with degraded signal due to effect of inter symbol interference (ISI).

    An all-optical UWB pulses generation and modulation scheme using cross phase modulation (XPM) effect of semiconductor optical amplifier (SOA) and DWDM-based multi-channel frequency discrimination is proposed and demonstrated, which has potential application in multiuser UWB-Over-Fiber communication systems. When a Gaussian pulse light and a wavelength-tunable CW probe light are together injected into the SOA, the probe light out from the SOA will have a temporal chirp due to SOA-XPM effect. When the chirped probe light is tuned to the slopes of single DWDM channel transmittance curve, the optical phase modulation to intensity modulation conversion is achieved at DWDM that serves as a multi-channel frequency discriminator, the inverted polarity Gaussian monocycle and doublet pulse is detected by a photodetector, respectively. If the probe lights are simultaneously aimed to different slopes of several DWDM channels, multi-channel or binary-phase-coded UWB signal generation can be acquired. Using proposed scheme, pulse amplitude modulation (PAM), pulse polarity modulation (PPM) and pulse shape modulation (PSM) to UWB pulses also can be conveniently realized.

    2016-01-01

    Semi-analytic models are developed to deterministically calculate the variances of degenerate and non-degenerate four-wave-mixing (FWM) noises for dispersion-managed dense wavelength division multiplexing (DWDM) systems with pure and mixed differential quadrature-phase-shift keying (DQPSK)/differential phase-shift keying (DPSK)/on-off-keying (OOK) channels. The semi-analytic models include various important propagation effects for exact numerical results. The novel dispersion map used here for dispersion management is composed of effective-area-enlarged positive dispersion fiber (EE-PDF), dispersion slope and dispersion compensating fiber (SCDCF) and nonzero dispersion-shifted fiber (NZ-DSF). It is numerically validated with the new models that, under the condition that all channels have the same average launch powers and baud rates, the impact of FWM noise for mixed DQPSK/OOK channels are more severe than that for pure DQPSK and mixed DQPSK/DPSK channels. It is also shown that the FWM efficiency is strongly dependent on the peak power of launched optical pulse for a large number of channels, as can be mainly attributed to the quasi-linear evolution of pulse shapes in pump channels induced by cross-phase modulation (XPM). Compared with some commercial optical-fiber transmission simulators, massive time-consuming can be avoided by using the newly derived semi-analytic models when transmission performances of such DWDM systems are numerically optimized and evaluated.

    2009-03-02

    We propose and demonstrate simultaneous optoelectronic NRZ-to-RZ regenerative format conversion for multiple DWDM channels using a single phase modulator (PM) and a fibre delay-interferometer (DI). In order to accommodate multiple DWDM channels, the DI is designed to have a free spectral range (FSR) equal to the channel spacing. This thus extracts the chirp induced by the phase modulation for all the channels at the same time. Since the original carriers are suppressed to some extent, the NRZ-to-RZ conversions can be achieved with regeneration. Multi-channel format conversion is successfully demonstrated for 16 channels at 10 Gb/s and 8 channels at 20 Gb/s, with a channel spacing of 100 GHz. Bit error ratio (BER) measurements at 10 Gb/s show 3.5 and 4.2 dB penalty improvements for 50 and 75 km transmission without dispersion compensation, respectively. Significant extinction ratio (ER) improvement and timing jitter reduction is observed for the converted channels.

    Full Text Available Many different budgeting techniques can be used in libraries, and some combination of these will be appropriate for almost any individual situation. Li-ne-item, program, performance, formula, variable, and zero-base budgets all have features that may prove beneficial in the preparation of a budget. Budgets also serve a variety of functions, providing for short-term and long-term financial planning as well as for cash management over a period of time. Short-term plans are reflected in the operating budget, while long-term plans are reflected in the capital budget. Since the time when cash is available to an organization does not usually coincide with the time that disbursements must be made, it is also important to carefully plan for the inflow and outflow of funds by means of a cash budget.      During the budget process an organization selects its programs and activities by providing the necessary funding; the library, along with others in the organization, must justify its requests. Because of the cyclical nature of the budget process, it is possible continually to gather information and evaluate alternatives for the next budget period so that the library may achieve its maximum potential for service to its patrons.

    Full Text Available In the design of new components for passive optical networks (PONs, the non-ideal properties are worth considering. In this paper the influence of interface roughness and temperature changes on final transmittance of downstream channels blocking filters for next generation dense wavelength division multiplexing passive optical networks(DWDM-PONs is shown. The transmittance as the filter transfer characteristicswas calculated with the transfer matrix method. The roughness was expressed by root mean square deviations from an ideally smooth surface and was taken into account in the modified Fresnel coefficients. It is demonstrated how the interfacial roughness may increase the insertion loss and decrease the channel bandwidth which results in reduction of transmitted light energy through the filter.

    This paper successfully demonstrate point-to-point (P2P) 2.5 TB/s DWDM system in downstream for 100 wavelengths having 0.4 nm (50 GHz) channel spacing by using post-dispersion compensation scheme. Each channel is transmitting 25 GB/s data rate in down link. A 20 km dispersion compensating fiber (DCF) followed by 80 km standard single mode fiber (SSMF) which passes 20 times through fiber span for compensating the chromatic dispersion. The maximum reach of designed system is (100×20) 2,000 km. In this paper we also performed the comparison of different modulation formats such as NRZ, RZ and CRZ. It has been observed that CRZ modulation format can achieve BER as better as e-9 for each channel, which gives best performance. The performance of designed system is compared in terms of Q-factor, eye diagrams and BER.

    We demonstrate simultaneous NRZ-to-RZ conversion for 16 DWDM channels, using a single SOA and a subsequent delay interferometer (DI) acting as a comb-like filter to control the obtained pulse-width for all of the channels. The SOA is operated in deep saturation, resulting in weak cross gain modulation and cross phase modulation induced crosstalk between different NRZ channels. By adjusting the detuning between the peaks in the DI spectrum and each corresponding carrier, good quality RZ signals with different duty cycles can be achieved. Bit-error-rate measurements show negative power penalties for the obtained RZ signals with different duty cycles. Significant timing jitter reductions for all channels show the good regenerative performance of the proposed converter.

    Full Text Available In this work, we present an analysis of physical layer performance of a DWDM-link of 66 km of single-mode optical fiber on which is implemented a SDH system to send STM-1 at 155 Mbps. We show the computational simulation in Optisystem 7.0 (Evaluation Version to analyze the DWDM system characteristic at 2.5 Gbps equivalent to a STM-16 frame. The results of the eye diagram and BER show that is possible to distinguish between bits when the detector thermal-noise is less than 1x10-19 W/Hz. We analyze experimental measurements of jitter and its corresponding comparison with the value normalized by the ITU-T for a STM-1 frame. The use of more wavelengths is proposed to maximize the transmission capacity of fiber optics or installation of interfaces with high capacity for increasing the available bandwidth.

    Saturated Collision Amplifier (SCA) is a novel amplification scheme that uses SOA saturation in order to maximize the output power and minimize the ASE noise and the polarization sensitivity. We demonstrate the SCA reach extension in a commercial single-wavelength XGPON1 prototype system where bidirectional optical budget of up to 50 dB is obtained. The traffic performances are compared between the SCA and the conventional SOA extender. The novel extension scheme is demonstrated also for two- and four-wavelength 10 Gbit/s unidirectional downstream configurations with 45 km and 100 km transmission distances with 58-dB maximum total optical budget for each wavelength. © 2011 Optical Society of America

    We investigate reduction of mode partition noise of a spectrally sliced Fabry-Perot laser diode (FP-LD) for application to seeded DWDM systems. The proposed scheme for the noise reduction incorporates a fiber-based Mach-Zehnder interferometer (MZI) and a reflective semiconductor optical amplifier (RSOA). The MZI enables to reduce a relative intensity noise (RIN) more than 3 dB with better noise distributions. Experimental results of 10-Gb/s signal transmission exhibit a considerable bit-error-rate (BER) reduction by three orders of magnitude at the given received power. After the noise reduction, the FP-LD is applied to a 10-Gb/s DWDM system as a seed-light-source. In a local-seeding scheme, return-to-zero (RZ) and carrier-suppressed (CS)-RZ signal formats are compared as a function of transmission distance. Furthermore, a back-reflection induced impairment is evaluated in a remote-seeding scheme. We also count the number of useable channels to show the feasibility of DWDM transmission.

Budgetary policy is official government Doctrine vision mirror and also represents a starting point for other public policies, which in turn are financed by the public budget. Fiscal policy instruments at its disposal handles the public sector in its structure, and the private sector. Tools such as grant, budgetary allocation, tax, welfare under various forms, direct investments and not least the state aid is used by the state through their budgetary policies to directly and indirectly infuence sector, and the private. Fiscal policies can be grouped according to the structure of the public sector in these components, namely fiscal policy, budgeting and resource allocation policies for financing the budget deficit. An important issue is the financing of the budget deficit budgetary policies. There are two funding possibilities, namely, the higher taxes or more axles site and enter the second call to public loans. Both options involve extra effort from taxpayers in the current fiscal year when they pay higher taxes or a future period when public loans will be repaid. We know that by virtue of "fiscal pact" structural deficits of the member countries of the EU are limited by the European Commission, according to the macro structural stability and budget of each Member State. This problem tempers to some extent the governments of the Member States budgetary appetite, but does not solve the problem of chronic budget deficits. Another issue addressed in this paper is related to the public debt, the absolute amount of its relative level of public datoriri, about the size of GDP, public debt financing and its repayment sources. Sources of public debt issuance and monetary impact on the budget and monetary stability are variables that must underpin the justification of budgetary

    Full Text Available We present a novel scheme of an excellent flat-top 25 GHz optical interleaver based on two ring configurations. And the Advanced Systems Analysis Program (ASAP optical modeling software has been utilized for the interleaver design. The optical path difference for interference and the phase shift are provided by the interferometer with two birefringent crystals and dual-ring arrangement. The proposed structure exhibits the passband utilization of more than 90% and the channel isolation greater than 95 dB within the C-band. Furthermore, we improve the dispersion performance by employing λ/6 wave plates as birefringent compensators for interleavers. The research results illustrate that our proposed scheme with compensator can improve the dispersion of more than 85.8%. Comparing the performance with the previous studies of optical interleavers with birefringent crystal and ring structure, the proposed system can achieve an excellent 25 GHz multichannel filter for dense wavelength division multiplexing (DWDM transmission systems.

The system is tested for external transmitter with NRZ (Non-Return Zero encoder using Mech-Zehnder modulator, which accepts input from CW (Continuous Wave laser array and low pass Bessel filter that supports PIN photodiode at receiver end. System performance for optical channels has been compared by varying channel length of EDFA (Erbium Doped Fiber Amplifier and Raman amplifiers to identify its impact in the sense of eye diagram, QF (Quality Factor and minimum BER (Bit Error Rate. Experimental setup was done by varying channel lengths of 60, 100, 120, 150 and 170Kms. It was found that EDFA has better performance in the sub-low ranges of 60Kms, whereas Raman offers better performance at wider channel lengths i.e. more than 100Kms. The proposed work can be extend for the avoidance of amplifier utilization at wider ranged.

    In this paper a high efficiency optical power splitter based on two-dimensional photonic crystals is proposed. The photonic crystal cavity is assumed to be constructed by TiO2 nanorods with refractive index n=2.609. To do so, first we implement some techniques to design a 1*2 optical power splitter, which include Y-shape waveguides and various types of defects such as point and line defects. The results of numerical simulations show that at the wavelength range of DWDM systems, the proposed 1*2 power splitter has the maximum efficiency of 99.616 %. A similar method is employed to design a 1*4 splitter with high performance operation at the same wavelength range which relates to the efficiency of 99.21 % that is the highest amount between these type of power splitters. The final size of these high efficiency power splitters is 130μm2 (10μm*13μm) which make them suitable for integrated optical circuits.

    The Integrated Budget Office Toolbox (IBOT) combines budgeting, resource allocation, organizational funding, and reporting features in an automated, integrated tool that provides data from a single source for Johnson Space Center (JSC) personnel. Using a common interface, concurrent users can utilize the data without compromising its integrity. IBOT tracks planning changes and updates throughout the year using both phasing and POP-related (program-operating-plan-related) budget information for the current year, and up to six years out. Separating lump-sum funds received from HQ (Headquarters) into separate labor, travel, procurement, Center G&A (general & administrative), and servicepool categories, IBOT creates a script that significantly reduces manual input time. IBOT also manages the movement of travel and procurement funds down to the organizational level and, using its integrated funds management feature, helps better track funding at lower levels. Third-party software is used to create integrated reports in IBOT that can be generated for plans, actuals, funds received, and other combinations of data that are currently maintained in the centralized format. Based on Microsoft SQL, IBOT incorporates generic budget processes, is transportable, and is economical to deploy and support.

    Full Text Available Budgets are an important part of the business environment since 1920 and are considered to be the key drivers and evaluators of managerial performance; and the key elements for planning and control. Budgets are the most powerful tool for management control; they can play an essential role in the organization’s power politics because it can increase the power and authority of top management and limit the autonomy of lower-level managers. Besides its advantages traditional budgeting presents disadvantages also. In recent years criticism towards traditional budgeting has increased. The basis of this criticism is that traditional budgeting is a relic of the past; it prevents reactions to changes in the market, it cannot keep up with the changes and requirements of today’s business world and it isn’t useful for business management. In order to eliminate criticism researchers and practitioners have developed more systematic and alternative concepts of budgeting that suits better for the needs of the modern business environment. Beyond budgeting, better budgeting, rolling forecasts, activity-based budgeting are the main alternatives developed in the last years. From the mentioned alternatives this article examines only beyond budgeting. Our paper discusses how budgeting has evolved into its current state, before examining why this universal technique has come under such heavy criticism of late. The paper is a literature analysis, it contributes to the existing managerial accounting literature and it is structured as follows. In the first part the background and evolution of budgeting is presented, followed by the analysis of related theories in traditional budgeting, emphasizing both the advantages and disadvantages of traditional budgeting. The second part of the paper continues with the discussion about alternative budgeting methods highlighting pros and cons of alternative methods, especially beyond budgeting.

Polarization Division Multiplexing (PDM and Dense Wavelength Division Multiplexing (DWDM techniques are also proposed in this system to increase total system data rate. For the ultra-high capacity need of SDM, Few Mode Fiber (FMF was proposed as SDM best technology for obtaining ultra-high bit rates with long haul transmission. The description and design of 8-DWDM channels over 7 modes SDM/PDM system was explored as future of ultra-high capacity optical network. A long-haul transmission of 1080 Km recorded for 8-WDM channels-7modes-SDM/PDM system by using QPSK modulation format. The total bit rate achieved by our designed system is 4.48 Tb/s at 40Gb/s. Channel estimation techniques were proposed to enable the transmitter pre-shaping design for the linear effects mitigation by using different DSP algorithms. The presence of linear and nonlinear losses limits the acceptable range of input power that produce the required BER for our proposed system from -4dBm to 4dBm.

  3. DWDM channel spacing tunable optical TDM carrier from a mode-locked weak-resonant-cavity Fabry-Perot laser diode based fiber ring.

    2008-08-18

    A novel optical TDM pulsed carrier with tunable mode spacing matching the ITU-T defined DWDM channels is demonstrated, which is generated from an optically injection-mode-locked weak-resonant-cavity Fabry-Perot laser diode (FPLD) with 10%-end-facet reflectivity. The FPLD exhibits relatively weak cavity modes and a gain spectral linewidth covering >33.5 nm. The least common multiple of the mode spacing determined by both the weak-resonant-cavity FPLD and the fiber-ring cavity can be tunable by adjusting length of the fiber ring cavity or the FPLD temperature to approach the desired 200GHz DWDM channel spacing of 1.6 nm. At a specific fiber-ring cavity length, such a least-common- multiple selection rule results in 12 lasing modes between 1532 and 1545 nm naturally and a mode-locking pulsewidth of 19 ps broadened by group velocity dispersion among different modes. With an additional intracavity bandpass filter, the operating wavelength can further extend from 1520 to 1553.5 nm. After channel filtering, each selected longitudinal mode gives rise to a shortened pulsewidth of 12 ps due to the reduced group velocity dispersion. By linear dispersion compensating with a 55-m long dispersion compensation fiber (DCF), the pulsewidth can be further compressed to 8 ps with its corresponding peak-to-peak chirp reducing from 9.7 to 4.3 GHz.

Baseline Budgeting for Continuous Improvement was created as a result of a newly named company president's request to implement zero-based budgeting. The president was frustrated with the mind-set of the organization, namely, "Next year's budget should be 10 to 15 percent more than this year's spending." Zero-based budgeting was not the answer, but combining the principles of activity-based costing and the Just-in-Time philosophy of eliminating waste and continuous improvement did provide a solution to the problem.

    Full Text Available The purpose of the paper is to determine the nature, targets, functions, principles and methods of budget planning and development of classifications due to its types. The essence of budget planning presented by various authors, is own interpretation (the process of developing a plan of formation, distribution and redistribution of financial funds according to budget system units during the reporting period based on budgetary purposes and targets defined by socio-economic development strategy is proposed. Methodology. The following methods such as cognition, induction, deduction, analysis and synthesis have been used in the process of survey. Results of the survey proves that budget planning plays an essential role in the financial management. On condition business environment changing even the best management system can become obsolete. The immediate reaction to the new trends in the financial system as a whole, in the industry is possible with budget planning as well. It also allows to make appropriate adjustments to the plans. Adjustment of long-term, medium-term and short-term plans makes it possible, without changing goals, to change ways of their achievement and thus to raise the level of efficiency of budget funds formation and use. It is necessary to revise the whole system plans, including their mission and goals in the case of global changes in the external and internal environment. Practical implications. The proposed approach to the classification of budget planning types allows to cope with the shortcomings of modern planning in the public sector (the development of the targets according to the state budget expenditures in Ukraine remains a formality and it rarely complies with realities. Value/originality is specified in the proposed interpretation which differs from existing ones that provides clarification of budget planning purpose in financial management; classification of budget planning principles, which differs from previous

    Full Text Available Having an efficient budget normally has different advantages such as measuring the performance of various organizations, setting appropriate targets and promoting managers based on their achievements. However, any budgeting planning requires prediction of different cost components. There are various methods for budgeting planning such as incremental budgeting, program budgeting, zero based budgeting and performance budgeting. In this paper, we present a fuzzy goal programming to estimate operational budget. The proposed model uses fuzzy triangular as well as interval number to estimate budgeting expenses. The proposed study of this paper is implemented for a real-world case study in province of Qom, Iran and the results are analyzed.

    Full Text Available Introduction: to evaluate the impact on the Italian National Health Service (NHS budget of the recent introduction of the DPP-4 inhibitor vildagliptin in combination treatment for NIDDM patients. Methods: NIDDM patients eligible to vildagliptin treatment were identified and quantified based on approved indications and prevalence data review; adequate alternative strategies were identified; direct medical costs associated with competing strategies were calculated according to national practice and prices (drug acquisition, therapeutic monitoring, cost for managing severe adverse events – severe hypoglycemia events, fractures, new heart failure cases and the NHS budgetary impact was estimated according to market penetration assumptions (base-case: 5% and 10% for the first and second year, respectively. Results: patients estimated eligible for vildagliptin in Italy are about 237,500: pts inadequately controlled with metformin monotherapy (166,500, pts inadequately controlled with sulfonylurea monotherapy and intolerant/contraindicated to metformin (70,200, and those inadequately controlled with thiazolidinedione monotherapy (800. Costing and comparing of the vildagliptin-based and competing strategies revealed differences in both directions, depending on patient subgroup. Assuming uniform penetration among identified patient subgroups, vildagliptin introduction is expected to raise NHS costs by 2,750,000 Euro in the first and by 5,500,000 Euro in the second year, respectively representing 1,6% and 3,2% of the estimated total management cost of this patient population. Conclusions: the introduction of vildagliptin in the treatment of Italian NIDDM patients offers a new therapeutic option for three inadequately controlled NIDDM subpopulations; the financial impact on Italian NHS expenditures depends on patient selection and can be expected not to exceed 2-3% of the currently dedicated budget in the first two years.

    Accurate assessment of anthropogenic carbon dioxide (CO2) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere - the "global carbon budget" - is important to better understand the global carbon cycle, support the development of climate policies, and project future climate change. Here we describe data sets and methodology to quantify all major components of the global carbon budget, including their uncertainties, based on the combination of a range of data, algorithms, statistics, and model estimates and their interpretation by a broad scientific community. We discuss changes compared to previous estimates and consistency within and among components, alongside methodology and data limitations. CO2 emissions from fossil fuels and industry (EFF) are based on energy statistics and cement production data, respectively, while emissions from land-use change (ELUC), mainly deforestation, are based on combined evidence from land-cover change data, fire activity associated with deforestation, and models. The global atmospheric CO2 concentration is measured directly and its rate of growth (GATM) is computed from the annual changes in concentration. The mean ocean CO2 sink (SOCEAN) is based on observations from the 1990s, while the annual anomalies and trends are estimated with ocean models. The variability in SOCEAN is evaluated with data products based on surveys of ocean CO2 measurements. The global residual terrestrial CO2 sink (SLAND) is estimated by the difference of the other terms of the global carbon budget and compared to results of independent dynamic global vegetation models. We compare the mean land and ocean fluxes and their variability to estimates from three atmospheric inverse methods for three broad latitude bands. All uncertainties are reported as ±1σ, reflecting the current capacity to characterise the annual estimates of each component of the global carbon budget.

    We have generated 4 x 100-Gb/s orthogonal WDM optical signal by employing polarization-division-multiplexed (PDM) return-to-zero (RZ) QPSK modulation format and tight optical filtering technique. The required optical signal-to-noise ratio (OSNR) at bit error ratio (BER) of 2 x 10(-3) for the 400 Gb/s orthogonal DWDM signal is measured to be approximately 22.8 dB/0.1 nm. After transmission over 1040-km standard single mode fiber (EDFA-only amplification, 80-km amplifier span and fully receiver-side electrical dispersion compensation), the measured BER for all the four orthogonal subchannels are smaller than 2 x 10(-3).

    The performance of dense wavelength division multiplexed (DWDM) soliton transmission system for returnto-zero (RZ) and non-return-to-zero (NRZ) modulation formats have been investigated. The main aim of this paper is to estimate and mitigate the four wave mixing (FWM) power by using in-line optical phase conjugator (OPC). The effect of FWM has been estimated using real fiber link having nonlinear and attenuation losses. The FWM power is strongly suppressed by introducing destructive interference between the first and second halves of in-line OPC. It has been indicated that RZ with OPC yields the better performance with FWM power suppression (more than 20 dBm in certain cases) with reasonable bit error rate and Q-factor.

    We demonstrate and characterize polarization-division multiplexed (PDM) DWDM data transmission for the first time in a range of systems incorporating a net-gain polarization-insensitive fiber optical parametric amplifier (PI-FOPA) for loss compensation. The PI-FOPA comprises a modified diversity-loop architecture to achieve 15dB net-gain, and up to 2.3THz (~18nm) bandwidth. Three representative systems are characterized using a 100Gb/s PDM-QPSK signal in conjunction with emulated DWDM neighbouring channels: (a) a 4x75km in-line fiber transmission system incorporating multiple EDFAs and a single PI-FOPA (b) N cascaded PI-FOPA amplification stages in an unlevelled Nx25km recirculating loop arrangement, with no EDFAs used within the loop signal path, and (c) M cascaded PI-FOPA amplification stages as part of an Mx75.6km gain-flattened recirculating loop system with the FOPA compensating for the transmission fiber loss, and EDFA compensation for loop switching and levelling loss. For the 4x75km in-line system (a), we transmit 45x50GHz-spaced signals ('equivalent' data-rate of 4.5Tb/s) with average OSNR penalty of 1.3dB over the band at 10 -3 BER. For the unlevelled 'FOPA-only' 25.2km cascaded system (b), we report a maximum of eight recirculations for all 10x100GHz-spaced signals, and five recirculations for 20x50GHz-spaced signals. For the 75.6km levelled system (c), we achieve eight recirculations for all 20x50GHz signals resulting in a total transmission distance of 604.8km.

  9. On reading the federal budget.

    Science.gov (United States)

    1974-03-01

    Within the scientific community there seem to be at least two schools of thought as far as the federal budget is concerned. One holds that more money would be made available for research if only spokesmen for research could gain access to high government officials. The other view is that the research budget of the United States reflects well-considered policy and cannot be changed by friendly persuasion. Rashi Fein, professor of the economics of medicine at Harvard Medical School, believes the latter. He expressed his point of view recently in an address before the American Public Health Association. His remarks were directed to last year's budget but apply equally to the President's budget for fiscal 1975. Excerpts from his talk, "The new national health spending policy-who pays and who gets?" follow.

  12. Balancing regional sea level budgets

    2015-12-01

    Balancing the sea-level budget is critical to understanding recent and future climate change as well as balancing Earth's energy budget and water budget. During the last decade, advancements in the ocean observing system — satellite altimeters, hydrographic profiling floats, and space-based gravity missions — have allowed the global mean sea level budget to?be assessed with unprecedented accuracy from direct, rather than inferred, estimates. In particular, several recent studies have used the sea-level budget to bound the rate of deep ocean warming [e.g. Llovel et al. 2014]. On a monthly basis, the sum of the steric component estimated from Argo and the ocean mass (barostatic) component from GRACE agree total sea level from Jason within the estimated uncertainties with the residual difference having an r.m.s. of less than 2 mm [Leuliette 2014]. Direct measurements of ocean warming above 2000 m depth during January 2005 and July 2015 explain about one-third of the observed annual rate of global mean sea-level rise. Extending the understanding of the sea-level budget from global mean sea level to regional patterns of sea level change is crucial for identifying regional differences in recent sea level change. The local sea-level budget can be used to identify any systematic errors in the global ocean observing system. Using the residuals from closing the sea level budget, we demonstrate that systematic regional errors remain, in part due to Argo sampling. We also show the effect of applying revised geocentric pole-tide corrections for GRACE [Wahr et al. 2015] and altimetry [Desai et al., 2015].

    Full Text Available Uno de los medios de transmisión de alta velocidad más utilizados en nuestro entorno es la fibra óptica especificada en el estándar ITU-T G.625; sin embargo, su despliegue y utilización plantea en la actualidad varios desafíos a resolver debido a su característica de no linealidad, dentro de los cuales se encuentra el relacionado con la disminución del nivel de interferencia. Con el ánimo de brindar un aporte en la solución de esta problemática se propone modelar el comportamiento no lineal de FWM cuando se implementan sistemas de multiplexación de longitudes de onda por un único hilo de fibra óptica a fin de poder estimar las características fundamentales que rige esta tecnología y poder plantear un algoritmo que sea capaz de reducir la interferencia no lineal de cuarta onda (FWM. Como conclusión principal se encontró que el modelo propuesto reduce la interferencia no lineal FWM, lo que permite un aumento en la asignación de canales DWDM aumentando el ancho de banda establecido en cada enlace óptico.

  9. Simultaneous frequency stabilization and high-power dense wavelength division multiplexing (HP-DWDM) using an external cavity based on volume Bragg gratings (VBGs)

    2016-03-01

    Multiplexing technologies enable the development of high-brightness diode lasers for direct industrial applications. We present a High-Power Dense Wavelength Division Multiplexer (HP-DWDM) with an average channel spacing of 1.7 (1.5) nm and a subsequent external cavity mirror to provide feedback for frequency stabilization and multiplexing in one step. The "self-optimizing" multiplexing unit consists of four reflective Volume Bragg Gratings (VBGs) with 99% diffraction efficiency and seven dielectric mirrors to overlay the radiation of five input channels with an adjustable channel spacing of 1-2 nm. In detail, we focus on the analysis of the overall optical efficiency, the change of the beam parameter product and the spectral width. The performance is demonstrated using five 90 μm multimode 9xx single emitters with M2<=17. Because of the feedback the lateral (multimodal) spatial and angular intensity distribution changes strongly and the beam parameter product decreases by a factor of 1.2 to 1.9. Thereby the angular intensity distribution is more affected than the width of the beam waist. The spectral width per emitter decreases to 3-200 pm (FWHM) depending on the injection current and the reflectance of the feedback mirror (0.75%, 1.5%, 4%, 6% or 8%). The overall optical multiplexing efficiency ranges between 77% and 86%. With some modifications (e.g. enhanced AR-coatings) we expect 90-95%.

    Directory of Open Access Journals (Sweden)

    Pablo de Andrés

    2015-01-01

    Full Text Available This paper seeks to shed further light on the capital budgeting techniques used by Spanish companies. Our paper posits that the gap between theory and practice might be related to the nature of sources of value and to the efficiency of mechanisms aligning managerial and shareholder incentives, rather than to resource restrictions or model misinterpretation. We analyze data from a survey conducted in 2011, the final sample comprising 140 non-financial Spanish firms. Our findings show a behaviour pattern similar to that reported in prior research for firms in other countries. Particularly noteworthy is that payback appears to be the most widely used tool, while real options are used relatively little. Our results confirm that size and industry are related to the frequency of use of certain capital budgeting techniques. Further, we find that the relevance of growth opportunities and flexibility is an important factor explaining the use of real options.

    The U.S. Congress has determined that the safe use of nuclear materials for peaceful purposes is a legitimate and important national goal. It has entrusted the Nuclear Regulatory Commission (NRC) with the primary Federal responsibility for achieving that goal. The NRC`s mission, therefore, is to regulate the Nation`s civilian use of byproduct, source, and special nuclear materials to ensure adequate protection of public health and safety, to promote the common defense and security, and to protect the environment. The NRC`s FY 1998 budget requests new budget authority of $481,300,000 to be funded by two appropriations - one is the NRC`s Salaraies and Expenses appropriation for $476,500,000, and the other is NRC`s Office of Inspector General appropriation for $4,800,000. Of the funds appropriated to the NRC`s Salaries and Expenses, $17,000,000, shall be derived from the Nuclear Waste Fund and $2,000,000 shall be derived from general funds. The proposed FY 1998 appropriation legislation would also exempt the $2,000,000 for regulatory reviews and other assistance provided to the Department of Energy from the requirement that the NRC collect 100 percent of its budget from fees. The sums appropriated to the NRC`s Salaries and Expenses and NRC`s Office of Inspector General shall be reduced by the amount of revenues received during FY 1998 from licensing fees, inspection services, and other services and collections, so as to result in a final FY 1998 appropriation for the NRC of an estimated $19,000,000 - the amount appropriated from the Nuclear Waste Fund and from general funds. Revenues derived from enforcement actions shall be deposited to miscellaneous receipts of the Treasury.

  1. Does National Culture Impact Capital Budgeting Systems?

    Directory of Open Access Journals (Sweden)

    Peter J. Graham

    2017-06-01

    Full Text Available We examine how national culture impacts organisational selection of capital budgeting systems to develop our understanding of what influence a holistic formulation of national culture has on capital budgeting systems. Such an understanding is important as it would not only provide a clearer link between national culture and capital budgeting systems and advance extant literature but would also help multinational firms that have business relationships with Indonesian firms in suitably designing strategies. We conducted semi-structured interviews of selected finance managers of listed firms in Indonesia and Australia. Consistent with the contingency theory, we found that economic, political, legal and social uncertainty impact on the use of capital budgeting systems. The levels of uncertainty were higher in Indonesia than Australia and need to be reckoned in the selection of capital budgeting systems used by firms. We also found that firms are influenced by project size and complexity, when selecting capital budgeting systems.

    Full Text Available This paper reports a study of the full carbon (C-CO2 budget of the Australian continent, focussing on 1990–2011 in the context of estimates over two centuries. The work is a contribution to the RECCAP (REgional Carbon Cycle Assessment and Processes project, as one of numerous regional studies. In constructing the budget, we estimate the following component carbon fluxes: net primary production (NPP; net ecosystem production (NEP; fire; land use change (LUC; riverine export; dust export; harvest (wood, crop and livestock and fossil fuel emissions (both territorial and non-territorial. Major biospheric fluxes were derived using BIOS2 (Haverd et al., 2012, a fine-spatial-resolution (0.05° offline modelling environment in which predictions of CABLE (Wang et al., 2011, a sophisticated land surface model with carbon cycle, are constrained by multiple observation types. The mean NEP reveals that climate variability and rising CO2 contributed 12 ± 24 (1σ error on mean and 68 ± 15 TgC yr−1, respectively. However these gains were partially offset by fire and LUC (along with other minor fluxes, which caused net losses of 26 ± 4 TgC yr−1 and 18 ± 7 TgC yr−1, respectively. The resultant net biome production (NBP is 36 ± 29 TgC yr−1, in which the largest contributions to uncertainty are NEP, fire and LUC. This NBP offset fossil fuel emissions (95 ± 6 TgC yr−1 by 38 ± 30%. The interannual variability (IAV in the Australian carbon budget exceeds Australia's total carbon emissions by fossil fuel combustion and is dominated by IAV in NEP. Territorial fossil fuel emissions are significantly smaller than the rapidly growing fossil fuel exports: in 2009–2010, Australia exported 2.5 times more carbon in fossil fuels than it emitted by burning fossil fuels.

  9. Entropy Budget for Hawking Evaporation

    Directory of Open Access Journals (Sweden)

    Ana Alonso-Serrano

    2017-07-01

    Full Text Available Blackbody radiation, emitted from a furnace and described by a Planck spectrum, contains (on average an entropy of 3 . 9 ± 2 . 5 bits per photon. Since normal physical burning is a unitary process, this amount of entropy is compensated by the same amount of “hidden information” in correlations between the photons. The importance of this result lies in the posterior extension of this argument to the Hawking radiation from black holes, demonstrating that the assumption of unitarity leads to a perfectly reasonable entropy/information budget for the evaporation process. In order to carry out this calculation, we adopt a variant of the “average subsystem” approach, but consider a tripartite pure system that includes the influence of the rest of the universe, and which allows “young” black holes to still have a non-zero entropy; which we identify with the standard Bekenstein entropy.

  18. Political Budget Cycles in the European Union

    2016-01-01

    Full Text Available This paper provides research on the theme of the political budget cycles. The goal is to find out whether or not the government tries to manipulate the state budget and its components for the purpose of re-election across the countries of the European Union. In order to verify this theory a dynamic panel data model was used. The results were significant, but only if predetermined elections were not counted into the estimations. In that case, the theory of the political budget cycles could be accepted as valid for the EU countries. The main driving force of the political budget cycles across the countries of the European Union is fluctuation of the government expenditures. During the election year, the government expenditures are higher, and a year after the election, government expenditures are lower. This is reflected into the state budget balance.

    Full Text Available This paper analyzes both the causes and effects of budget amendment in Romania, taking into account the Fiscal Budget Responsibility Law. Reduction by 5% of the CSI payable by the employer from the 1st of October 2014 should be necessarily accompanied by a reform of the social security system, starting from the principle of equal treatment of taxpayers irrespective of their type of income and the elaboration and implementation of a medium-term strategy for financially rebalancing the social security budgets, especially the pensions' budget. Such a strategy should aim to increase the number of taxpayers, in particular by reducing "black" labor, and ensure a total transparency of budget expenditures as a whole in order to stimulate the growth of voluntary compliance to payment of taxes.

  3. Budget-makers and health care systems.

    Science.gov (United States)

    White, Joseph

    2013-10-01

    Health programs are shaped by the decisions made in budget processes, so how budget-makers view health programs is an important part of making health policy. Budgeting in any country involves its own policy community, with key players including budgeting professionals and political authorities. This article reviews the typical pressures on and attitudes of these actors when they address health policy choices. The worldview of budget professionals includes attitudes that are congenial to particular policy perspectives, such as the desire to select packages of programs that maximize population health. The pressures on political authorities, however, are very different: most importantly, public demand for health care services is stronger than for virtually any other government activity. The norms and procedures of budgeting also tend to discourage adoption of some of the more enthusiastically promoted health policy reforms. Therefore talk about rationalizing systems is not matched by action; and action is better explained by the need to minimize blame. The budget-maker's perspective provides insight about key controversies in healthcare policy such as decentralization, competition, health service systems as opposed to health insurance systems, and dedicated vs. general revenue finance. It also explains the frequency of various "gaming" behaviors. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    The WFIRST coronagraph instrument (CGI) will be the first in-space coronagraph using active wavefront control to directly image and characterize mature exoplanets and zodiacal disks in reflected starlight. For CGI systems engineering, including requirements development, CGI performance is predicted using a hierarchy of performance budgets to estimate various noise components — spatial and temporal flux variations — that obscure exoplanet signals in direct imaging and spectroscopy configurations. These performance budgets are validated through a robust integrated modeling and testbed model validation efforts.We present the performance budgeting framework used by WFIRST for the flow-down of coronagraph science requirements, mission constraints, and observatory interfaces to measurable instrument engineering parameters.

    Full Text Available Theoretical aspects of economic security in conjunction with budget components such as “budget interests” and “budget necessities” are analyzed. Key positions of the categories “budget interests” and “budget necessities” in the theory of economic security in the budgetary area are substantiated given their priority role in setting up its implementation strategy. The category “budget interests” is defined as the system of budget necessities of the interest holders, implemented through budget activities of entities and aimed at seeking benefits through the budget, in order to guarantee functioning and development of the society, the state, legal entities and physical persons. “Budget necessities” are defined as the need in budget funds to achieve and sustain, at a certain level, life activities of individuals, social groups, society, state and legal entities. Classification of budget interests by various criteria is made in the context of their impact on the economic security of the state. It is demonstrated that the four-tier classification of the budget interests by interest holder is essential to guaranteeing economic security in the budgetary area: budget interests of the state: the interests held by central and local power offices; budget interests of legal entities: the interests of profit and non-profit (public, budgetary, party and other organizations; budget interests of individuals: basic necessities of individuals, met by budget transfers, which stand out of the array of public necessities by their individual character.

  3. OPTIMIZING LOCAL BUDGET BALANCING IN ROMANIA

    Directory of Open Access Journals (Sweden)

    Gyorgy Adina Crsitina

    2011-07-01

    Full Text Available The importance of the local public finance is growing in accordance with the increasing proportion of the decentralization process. The mechanism of resource allocation, and especially the allocation criteria used, constitutes subjects of debate. Our objective pursued is to assess whether the avoidance of the first step for balancing the allocation of funds can provide enhanced fairness in balancing the local budgets across the country. Local budgets in Romania receive significant resources from the state budget in the form of amounts and quotas distributed from certain taxes, which are revenues for the state budget. Some of these amounts are designed to balance the local budgets. The distribution of funds from the state budget to the local budgets requires two steps. Firstly, the amounts are divided by county, secondly, these amounts are directed within the county especially towards localities which have a lower financial standing. Given the significant disparities between counties, we believe that this mechanism does not ensure fairness in the allocation because the funds distributed according to the first step may not use fair criteria to meet the requirements for balanced local budgets. Therefore, we intend to simulate a balanced allocation of national funds for eliminating the first step that produces the most significant inequities. Direct application of the second step of allocation, with its two phases, will provide more funds serving those local administrative units for the income tax per capita is lower than the national average. Comparing the values allocated for the year 2011 with those obtained in the simulation we will examine changes that occur after the application of this method which seems to be more equitable and appropriate.

    Full Text Available This paper investigates the application of Zero-Based Budgeting (ZBB system to budget implementation by the Federal Government of Nigeria by ascertaining among others, the relationship between ZBB approach and budget performance indices in Nigeria. To achieve the above, primary data were obtained through questionnaires that were specifically designed for this study. The data obtained were analysed with the SPSS version 21. The statistical tools employed were Analysis of Variance (ANOVA and Pearson Correlation Coefficiant (PCC. The Cronbach’s Alpha reliability test was used to test the internal consistency/reliability of the instrument used for the study. On the basis of the analysis, we found that there is significant difference in the effectiveness of ZBB in terms of budget implementation compared to the Traditional Budgeting System (TBS. It was also found that the application of ZBB tend to be performance-driven and is able to detect the redundant programmes/projects and staff, thereby recommending either realignment, discharge, transfer or redeployment of projects or resources. The study therefore, recommends among others that ZBB should be encouraged as a good means of budget implementation and also close monitoring of budget execution should be enshrined in work ethics at every stage of budget preparation and implementation in the country. This is believed would go a long way to strengthen measures aimed at mitigating poor budget implementation in the country.

  8. POLITICAL BUDGET CYCLES: EVIDENCE FROM TURKEY

    Directory of Open Access Journals (Sweden)

    FİLİZ ERYILMAZ

    2015-04-01

    Full Text Available The theorical literature on “Political Business Cycles” presents important insights on the extent to which politicians attempt to manipulate government monetary and fiscal policies to influence electoral outcomes, in particular, with the aim of re-election. In recent years “Political Budget Cycles” is the one of the most important topics in Political Business Cycles literature. According to Political Budget Cycles Theory, some components of the government budget are influenced by the electoral cycle and consequently an increase in government spending or decrease in taxes in an election year, leading to larger fiscal deficit. This incumbent’s fiscal manipulation is a tool that governments possess to increase their changes for re-election. In this paper we investigate the presence of Political Budget Cycles using a data set of budget balance, total expenditure and total revenue over the period 1994–2012. Our findings suggest that incumbents in Turkey use fiscal policy to increase their popularity and win elections, therefore fiscal manipulation was rewarded rather than punished by Turkish voters. The meaning of this result is that Political Budget Cycles Theory is valid for Turkey between 1994 and 2012.

The relevance of the work lies in the importance of general government in the regulation of macroeconomic balances by sizing or macroeconomic imbalances, with modern methods that analyze the possibilities and effects of new types of deficits or surpluses in the public sector.

  2. SAY NO TO NEW BUDGET CUTS !

    STAFF ASSOCIATION

    2010-01-01

    In June, CERN Finance Committee postponed its proposals for the 2011 budget and the Director-General’s medium-term plan (2012–2015). The Member State delegations asked for a significant reduction in these budgets. The Staff Association condemns this request for new budget cuts which shows a short-term political vision. It is therefore organizing a demonstration on 25th August to defend basic research in Europe. On this day your presence is indispensable. Enough of simply getting by ! We know that budget cuts and the reduction of deficits are topical in several countries. The areas of research and training are also affected. However, in the case of CERN, severe budgetary constraints have been imposed for several years now, in particular since 1996 when the Organization’s budget was reduced by around 10%, just when the construction of the LHC was due to start. Since then, 100 million Swiss francs have been lost each year, reducing CERN’s resources to a minimum. All e...

  3. PUBLIC EXPENDITURE ON HEALTH IN LOCAL BUDGETS

    2017-06-01

    Full Text Available This paper entitled "Public expenditure on health in local budgets" aims analysing and deepening major spending categories that public authorities finance at local level, namely health expenditure. In the first part of the article we have specified the content and role of this category of expenditure in local budgets and also made some feedback on decentralization in health. In the second part of the work, based on data available in Statistical Yearbook of Romania, we have carried out an analysis of the dynamics of health spending from local budgets to emphasize their place and role in the health care expenses. The research carried out follows that the evolution and structure of health expenditure financed from local budgets is determined, along with the legislative framework in the field, by several variables that differ from one territorial administrative unit to another: the existence of sanitary units, their type, the involving of local public authorities in their development and modernization, the number and the social structure of the population. The research shows that over the period 1993-2015, the dynamics of the share of health spending in total expenditures of local budgets is sinusoidal, with a minimum threshold in 2000 of only 0.3%.

    All administrators are expected to be competent in budget and financial management. Novice administrators of schools of nursing are expected to know about the budgetary process, budgeting techniques, and the various types of budgets that can be used, such as the open-ended budget, incremental budget, alternate-level budget, quota budget, formula budget, intramural budget, zero-based budget, and cost center budget. In addition, administrators are expected to know what key questions need to be asked about how the budget is structured and revenue sources and how to manage and evaluate their budgets.

  5. Budgeting in the Era of Judicial Independence

    Directory of Open Access Journals (Sweden)

    Jesper Wittrup

    2010-04-01

    Full Text Available In this paper judicial independence is viewed from the angle of economics. Economic historians have identified judicial independence as a key element in explaining why some nations have had a more successful economic development than others. Empirically it is shown that perceived judicial independence correlates with economic growth. I argue that the crucial importance of judicial independence and how it is perceived poses a challenge with regard to judicial budgeting, and that this true with regard to both basic models of judicial budgeting presently found in Europe: the traditional model which grants the authority to manage and allocate the judicial budget to the Ministry of Justice, and the more “modern” approach which grants this authority to an independent judicial council. However as illustrated with practical examples, in both cases the use of carefully designed and transparent statistical performance indicators may help authorities to deal more properly with the challenge posed by judicial independence.

    2014-11-01

    Full Text Available Budget as a management tool is used to size the activity of forecasting the financial and accounting terms and in terms of economic efficiency, the allocation and use of resources to an entity in a particular reporting period, that aims to achieve the necessary expenses and income achieved, establishing this and the powers and responsibilities relating to the efficient use of these resources. Sales budgeting should be given special attention given the correlation and the influence of these predictions with other budgets namely production budget; supplies budget; investment budget; budget overheads; treasury budget. There should be understood that estimates of other budgets are not related or that there are no dependencies between them.

  7. EXPENSES FOR ECONOMIC ACTIVITIES FROM LOCAL BUDGETS

    2015-04-01

    Full Text Available In the present article we propose to analyze and deepen significant categories of costs funded from the local budgets, namely the expenditure for economic activities. Our scientific approach begins with determining the place occupied by such expenses in local public expenditure by specifying their content and role. The center of gravity of the study is to treat and deepen the three subgroups of expenses that we consider representative: "The expenses for production, transportation, distribution and supply of heat in a centralized system", "Transport Costs" and Expenditure for agriculture and forestry ". The reaserch is based on the quantitative analysis of the expenses for economic actions, in local budgets, based on the existing data from the Statistical Yearbook of Romania, and highlights the structure of this type of expenses as well as the place they hold in the expediture of local budgets.The study includes an analysis of the dynamics of the share held by economic costs within total expenses from local budgets. From the reaserch carried out, it is shown that the evolution and structure of the expenditures for economic actions from local budgets is determined by the action of certain economical and social factors that vary from one administrative teritorial unit to another: the ray of economical develpoment of the administrative ter itorial unit, urbanization, the number and social structure of the population. The reaserch shows that in the field of expenses for economic actions, the largest share is held by expenditures for transportation (almost 80%, far away from the expenses for fuel and energy (13,66%. During the 1999-2013 the dynamic of expenses for economical actions in the total of expenditures of local budgets, is sinusoidal due to the intervention of certain legislative changes.

    2016-01-01

    Full Text Available For some time, quite a few countries have been facing a serious crisis of public finances. This crisis fundamentally determines their everyday lives; therefore, it comes as no surprise that the changes within the field of public budgeting are labelled as priorities. In this context, the questions of advancement of the public sector management, the process of making more quality decisions about public spending and the increase in the responsibility of the budget users become particularly important. The introduction and the gradual improvement of performance budgeting is an indisputable manifestation of an effort to reform the area of financing public spending. Performance budgeting, as an advanced model of public budgeting, is a huge step forward in the direction of providing a better usage of budget funds, achieving consolidation of public finances and being more successful in meeting the public needs. As the financing of the public sector entities (organisations, institutions is closely related to their performance, performance budgeting is also, to some extent, a suitable way to eliminate the shortcomings and modify the traditional 'philosophy' underlying the operation of the public sector, to rationalise the system of public expenditures and to manage them more successfully. Performance budgeting is complex by its nature and may not easily be performed in certain segments of the public sector. In many developed countries, it has been implemented for more than half a century. Monitoring and measuring the public sector performances, the increase in the scope and the improvement in the quality of public goods and provided public services are highly ranked goals in these countries, which are highly committed to instituting a more adequate control over the public funds and innovating their budget system in the direction of attaining the highest level of development.

    1995-06-01

    As vital as the nursing human resource budget is to the successful achievement of institutional goals, it is very important to present a well-developed budget. Using current automated spreadsheet technology, the nursing human resource budget can be laid out in a format that is easy to understand and easy to present. Using the methods discussed in this article, the nurse executive will be able to perform infinite iterations of the proposed budget with a few simple key strokes, thus allowing for things like zero-based budgeting or addition of programs during the budgeting process or at a later date. Implications for nurse executives are discussed.

  16. Kinetic energy budgets in areas of convection

    Science.gov (United States)

    Fuelberg, H. E.

    1979-01-01

    Synoptic scale budgets of kinetic energy are computed using 3 and 6 h data from three of NASA's Atmospheric Variability Experiments (AVE's). Numerous areas of intense convection occurred during the three experiments. Large kinetic energy variability, with periods as short as 6 h, is observed in budgets computed over each entire experiment area and over limited volumes that barely enclose the convection and move with it. Kinetic energy generation and transport processes in the smaller volumes are often a maximum when the enclosed storms are near peak intensity, but the nature of the various energy processes differs between storm cases and seems closely related to the synoptic conditions. A commonly observed energy budget for peak storm intensity indicates that generation of kinetic energy by cross-contour flow is the major energy source while dissipation to subgrid scales is the major sink. Synoptic scale vertical motion transports kinetic energy from lower to upper levels of the atmosphere while low-level horizontal flux convergence and upper-level horizontal divergence also occur. Spatial fields of the energy budget terms show that the storm environment is a major center of energy activity for the entire area.

    2017-04-01

    The energy budget of evolving accretionary systems reveals how deformational processes partition energy as faults slip, topography uplifts, and layer-parallel shortening produces distributed off-fault deformation. The energy budget provides a quantitative framework for evaluating the energetic contribution or consumption of diverse deformation mechanisms. We investigate energy partitioning in evolving accretionary prisms by synthesizing data from physical sand accretion experiments and numerical accretion simulations. We incorporate incremental strain fields and cumulative force measurements from two suites of experiments to design numerical simulations that represent accretionary wedges with stronger and weaker detachment faults. One suite of the physical experiments includes a basal glass bead layer and the other does not. Two physical experiments within each suite implement different boundary conditions (stable base versus moving base configuration). Synthesizing observations from the differing base configurations reduces the influence of sidewall friction because the force vector produced by sidewall friction points in opposite directions depending on whether the base is fixed or moving. With the numerical simulations, we calculate the energy budget at two stages of accretion: at the maximum force preceding the development of the first thrust pair, and at the minimum force following the development of the pair. To identify the appropriate combination of material and fault properties to apply in the simulations, we systematically vary the Young's modulus and the fault static and dynamic friction coefficients in numerical accretion simulations, and identify the set of parameters that minimizes the misfit between the normal force measured on the physical backwall and the numerically simulated force. Following this derivation of the appropriate material and fault properties, we calculate the components of the work budget in the numerical simulations and in the

  7. Global Energy and Water Budgets in MERRA

    Bosilovich, Michael G.; Robertson, Franklin R.; Chen, Junye

    2010-01-01

    Reanalyses, retrospectively analyzing observations over climatological time scales, represent a merger between satellite observations and models to provide globally continuous data and have improved over several generations. Balancing the Earth s global water and energy budgets has been a focus of research for more than two decades. Models tend to their own climate while remotely sensed observations have had varying degrees of uncertainty. This study evaluates the latest NASA reanalysis, called the Modern Era Retrospective-analysis for Research and Applications (MERRA), from a global water and energy cycles perspective. MERRA was configured to provide complete budgets in its output diagnostics, including the Incremental Analysis Update (IAU), the term that represents the observations influence on the analyzed states, alongside the physical flux terms. Precipitation in reanalyses is typically sensitive to the observational analysis. For MERRA, the global mean precipitation bias and spatial variability are more comparable to merged satellite observations (GPCP and CMAP) than previous generations of reanalyses. Ocean evaporation also has a much lower value which is comparable to observed data sets. The global energy budget shows that MERRA cloud effects may be generally weak, leading to excess shortwave radiation reaching the ocean surface. Evaluating the MERRA time series of budget terms, a significant change occurs, which does not appear to be represented in observations. In 1999, the global analysis increments of water vapor changes sign from negative to positive, and primarily lead to more oceanic precipitation. This change is coincident with the beginning of AMSU radiance assimilation. Previous and current reanalyses all exhibit some sensitivity to perturbations in the observation record, and this remains a significant research topic for reanalysis development. The effect of the changing observing system is evaluated for MERRA water and energy budget terms.

    Full Text Available Budgeting plays an important role on increasing efficiency of organizations. It helps determine targets and possible future chaos a head of time. A good budgeting plan can create motivation among workers and managers. There are different budgeting plans such as traditional and operational. In this paper, we analyze the effects of executing budgeting plan on governmental organizations. The proposed study of this paper designs a questionnaire consists of various questions and selects 94 people out of 125 financial managers who work for various governmental organizations in province of Zanjan, Iran. The results indicate that the operational budgeting could help provide better performance measurement of governmental organizations, it helps us provide a more precise cost of products and services, and it helps government allocate the necessary budget proportion to performance measurement. The results of our survey also indicate that operational budgeting redirect costs towards our objectives and make the overall budgeting crystal clear.

    2012-03-01

    President Barack Obama's proposed budget for the U.S. National Science Foundation (NSF) for fiscal year (FY) 2013 would provide the agency with $7.37 billion, a $340 million increase, 4.8% above the FY 2012 estimated budget under which NSF has been operating. NSF has fared well during previous budget cycles, and the Obama administration's budget document for FY 2013 states that “NSF plays a critical role in the implementation of the President's Plan for Science and Technology.” With federal agencies operating under tighter budgets in a difficult financial climate, NSF director Subra Suresh said the budget includes substantial increases for core programs, frontier science, education, and human resources. “I am confident that NSF merits the $7.4 billion the president proposed. I'm optimistic Congress will approve the budget,” Suresh said at a 13 February NSF budget briefing.

    Full Text Available The problems of methodological fundamentals of managerial accounting of manufacturing costs in information provision for budgeting, not only at the enterprise level, but also as it is required by current conditions of advanced control, in the context of structural production units of “responsibility centers” using “flexible” budgets, which are prepared during the manufacturing process are examined. Unlike a simple comparison of the regular budgets (scheduled amount of work divided by regulatory costs per unit, “flexible” budget makes adjustments to the planned budget because it represents the actual amount of work divided by regulatory costs, which is included with the comparison of the amount of work that are not fulfilled, or carried to a greater or lesser extent compared with the expected budget. Thus, “Flexible” budgets reveal the actual extent of the changes compared with the expected budget.

    We describe a new multicore fiber (MCF) having seven single-mode cores arranged in a hexagonal array, exhibiting low crosstalk among the cores and low loss across the C and L bands. We experimentally demonstrate a record transmission capacity of 112 Tb/s over a 76.8-km MCF using space-division multiplexing and dense wavelength-division multiplexing (DWDM). Each core carries 160 107-Gb/s polarization-division multiplexed quadrature phase-shift keying (PDM-QPSK) channels on a 50-GHz grid in the C and L bands, resulting in an aggregate spectral efficiency of 14 b/s/Hz. We further investigate the impact of the inter-core crosstalk on a 107-Gb/s PDM-QPSK signal after transmitting through the center core of the MCF when all the 6 outer cores carry same-wavelength 107-Gb/s signals with equal powers, and discuss the system implications of core-to-core crosstalk on ultra-long-haul transmission. © 2011 Optical Society of America

  10. Stress Analysis in Managing the Region’s Budget Risks

    Directory of Open Access Journals (Sweden)

    Natalya Pavlovna Pazdnikova

    2014-09-01

    Full Text Available The article addresses the implementation of budget risk management methods into the practices of governmental authorities. Drawing on the example of a particular region the article aims to demonstrate the possible methods of budget risk management. The authors refine the existing approaches to the notion of risk in its relation to budget system by introducing the notion of “budget risk.” Here the focus is the risk of default of budget spending in full which causes underfunding of territories and decrease in quality of life in the region. The authors have particularized the classification of budget risks and grouped together the criteria and factors which significantly influence the assessment and choice of method to manage budget risks. They hypothesize that budget risk is a financial risk. Therefore, the methods of financial risks management can be applied to budget risks management. The authors suggest a methodological approach to risk assessment based on correlation and regression analysis of program financing. The application of Kendall rank correlation coefficient allowed to assess the efficiency of budget spending on the implementation of state programs in Perm Krai. Two clusters — “Nature management and infrastructure” and “Public security” — turned out to be in the zone of high budget risk. The method of stress analysis, which consists in calculating Value at Risk (VaR, was applied to budget risks that in terms of probability are classified as critical. In order to assess risk as probability rate, the amount of Perm Krai deficit budget was calculated as induced variable from budget revenues and spending. The results demonstrate that contemporary management of public resources in the regions calls for the implementation of new management tools of higher quality and budget risk management is one of them.

    Latest developments Negotiations in Brussels in early February 2013 to define the long-term budget 2014 − 2020 of the European Union (EU) could result in a significant loss for the European research program 2020. It could be that the research program of the EU would have to face a decrease from the already low 80 billion euros proposed by the Commission in late 2012 to 69 billion euros (a decrease of almost 12 % or even more considering that the European Parliament had initially proposed a budget of 100 billion euros for Horizon 2020). Nevertheless let us hope that this will not be the "last word" on the funding of Horizon 2020 and that the European Parliament, which co-decides on the budget together with the European Council, which is composed of heads of government and tends to promote national interests, will reduce somewhat the significant loss of funds for research. Indeed, Parliament is generally more favorable to European research policy. In particular, the President of t...

  17. NEW TRENDS IN BUDGETING – A LITERATURE REVIEW

    Directory of Open Access Journals (Sweden)

    Ildikó Réka CARDOȘ

    2014-06-01

    Full Text Available Budgeting is universally used all over the world. Budgets are the most powerful tool for management control, they are the key drivers and evaluators of managerial performance. However, in recent years criticism towards traditional budgeting has been notably increased. Researchers consider that traditional budgeting is a relic of the past; it cannot keep up with the changes and requirements of today’s business world. As an answer, alternative budgeting concepts were developed, such as beyond budgeting, forecasting or activity-based budgeting. Our paper is a literature analysis. First, the background and evolution of budgeting is presented, emphasizing both the advantages and disadvantages of traditional budgeting. Second, we continue the discussion about alternative budgeting methods highlighting their pros and cons. Third, conducted surveys and studies are analyzed in order to establish whether traditional or alternative budgeting methods are better and have a positive impact on businesses; or which has more practical usefulness. The final part provides conclusions and discussions for future research.

  18. ANALYSIS OF BUDGET DEFICIT AND ITS PROBLEMS IN LITHUANIA

    Directory of Open Access Journals (Sweden)

    2015-10-01

    Full Text Available Budget deficit is one of the most important parts of macroeconomics. Since 1990, the government of the Lithuanian Republic has been faced with problems in balancing the budget deficit; most of the years, the country’s budget was deficit with the lack of incoming money flow. The budget deficit value in Lithuania has been a significant theme since 2004, when Lithuania became part of the European Union, and one of the liabilities was to insure the litas replacement with euro currency and the budget deficit was one of the Maastricht’s criteria. Also it is very important to maintain effective management of public finances. The government is responsible for managing the country’s budget in respect to various economical parameters, for example, GDP, inflation rate, unemployment rate, etc., in order to plan income level and distribute it to the relevant economic areas. Also, the budget deficit’s problems are revealed in this article.

  19. Budget goal commitment, clinical managers' use of budget information and performance.

    2014-08-01

    Despite the importance placed on accounting as a means to influence performance in public healthcare, there is still a lot to be learned about the role of management accounting in clinical managers' work behavior and their link with organizational performance. The article aims at analyzing the motivational role of budgetary participation and the intervening role of individuals' mental states and behaviors in influencing the relationship between budgetary participation and performance. According to the goal-setting theory, SEM technique was used to test the relationships among variables. The data were collected by a survey conducted in an Italian hospital. The results show that: (i) budgetary participation does not directly influence the use of budget information, but the latter is encouraged by the level of budget goal commitment which, as a result, is influenced by the positive motivational consequences of participative budgeting; (ii) budget goal commitment does not directly influence performance, but the relationship is mediated by the use of budget information. This study contributes to health policy and management accounting literature and has significant policy implications. Mainly, the findings prove that the introduction of business-like techniques in the healthcare sector can improve performance if attitudinal and behavioral variables are adequately stimulated.

    The global methane (CH4) budget is becoming an increasingly important component for managing realistic pathways to mitigate climate change. This relevance, due to a shorter atmospheric lifetime and a stronger warming potential than carbon dioxide, is challenged by the still unexplained changes of atmospheric CH4 over the past decade. Emissions and concentrations of CH4 are continuing to increase, making CH4 the second most important human-induced greenhouse gas after carbon dioxide. Two major difficulties in reducing uncertainties come from the large variety of diffusive CH4 sources that overlap geographically, and from the destruction of CH4 by the very short-lived hydroxyl radical (OH). To address these difficulties, we have established a consortium of multi-disciplinary scientists under the umbrella of the Global Carbon Project to synthesize and stimulate research on the methane cycle, and producing regular (˜ biennial) updates of the global methane budget. This consortium includes atmospheric physicists and chemists, biogeochemists of surface and marine emissions, and socio-economists who study anthropogenic emissions. Following Kirschke et al. (2013), we propose here the first version of a living review paper that integrates results of top-down studies (exploiting atmospheric observations within an atmospheric inverse-modelling framework) and bottom-up models, inventories and data-driven approaches (including process-based models for estimating land surface emissions and atmospheric chemistry, and inventories for anthropogenic emissions, data-driven extrapolations). For the 2003-2012 decade, global methane emissions are estimated by top-down inversions at 558 Tg CH4 yr-1, range 540-568. About 60 % of global emissions are anthropogenic (range 50-65 %). Since 2010, the bottom-up global emission inventories have been closer to methane emissions in the most carbon-intensive Representative Concentrations Pathway (RCP8.5) and higher than all other RCP scenarios

  2. THE REAL OPTIONS OF CAPITAL BUDGET

    Directory of Open Access Journals (Sweden)

    Antonio Lopo Martins

    2008-07-01

    Full Text Available The traditional techniques of capital budget, as the deducted cash flow and the net value present, do not incorporate existing flexibilities in an investment project, they tend to distort the value of certain investments, mainly those that are considered in scenes of uncertainty and risk. Therefore, this study intends to demonstrate that the Real Options Theory (TOR is a useful methodology to evaluate and to indicate the best option for project of expansion investment. To reach the considered objective the procedure method was used a case study, having as unit of case the Resort Praia Hotel do Litoral Norte of Salvador. This study was developed of the following form: first it identified the traditional net value present and later it was incorporated the volatileness of each analyzed uncertainty. Second, as the real options are analogous to the financial options, it was necessary to identify elements that composed the terminologies of the financial options with intention to get the value of the real option. For this model of options pricing of Black & Scholes jointly with a computational simulator was used (SLS to get the expanded net value present. As a result of this study it was possible to evidence that using the traditional tool of capital budget Net Value Present (VPL is negative, therefore the project of expansion of the Hotel would be rejected. While for the application of methodology TOR the project presents positive Expanded Present Value which would represent an excellent chance of investment. Key-word: Capital budget, Real options, Analysis of investments.

  3. Unforeseen costs of cutting mosquito surveillance budgets.

    Directory of Open Access Journals (Sweden)

    Gonzalo M Vazquez-Prokopec

    Full Text Available A budget proposal to stop the U.S. Centers for Disease Control and Prevention (CDC funding in surveillance and research for mosquito-borne diseases such as dengue and West Nile virus has the potential to leave the country ill-prepared to handle new emerging diseases and manage existing ones. In order to demonstrate the consequences of such a measure, if implemented, we evaluated the impact of delayed control responses to dengue epidemics (a likely scenario emerging from the proposed CDC budget cut in an economically developed urban environment. We used a mathematical model to generate hypothetical scenarios of delayed response to a dengue introduction (a consequence of halted mosquito surveillance in the City of Cairns, Queensland, Australia. We then coupled the results of such a model with mosquito surveillance and case management costs to estimate the cumulative costs of each response scenario. Our study shows that halting mosquito surveillance can increase the management costs of epidemics by up to an order of magnitude in comparison to a strategy with sustained surveillance and early case detection. Our analysis shows that the total costs of preparedness through surveillance are far lower than the ones needed to respond to the introduction of vector-borne pathogens, even without consideration of the cost in human lives and well-being. More specifically, our findings provide a science-based justification for the re-assessment of the current proposal to slash the budget of the CDC vector-borne diseases program, and emphasize the need for improved and sustainable systems for vector-borne disease surveillance.

    2005-01-01

    The paper presents a simple model for discussing the effects of deficit limits and budget rules on fiscal policy. I find that limits on deficit- output ratios provide incentives to implement procyclical policies when the economy is in intermediate states, and countercyclical policies only in very “good” and very “bad” economic times. As a result, fiscal “reaction functions” are not monotonically related to the state of the economy. Deficit limits are found to exert discipline only provided th...

  7. Budget Deficit and Macroeconomics Fundamentals: The case of Azerbaijan

    Directory of Open Access Journals (Sweden)

    Kahnim Farajova

    2011-08-01

    Full Text Available In recent years, the emergence of rising budget deficit is the main reason forcing economists to investigate the reasons for changes in fiscal balances. The purpose of the paper is to investigate the relationship between budget deficit and macroeconomic fundamentals using data from Azerbaijan. The empirical analysis applies ARDL Cointegration methodology in conjunction with Granger causality tests to provide evidence for both the long and short run dynamics between the variables involved in the analysis. Using the Error Correction specification, there was found evidence of long-run causality running from current account, real interest rate, GDP, inflation and exchange rate to budget deficit. There was also found evidence of short-run Granger causal effects running from current account and real interest rate towards budget deficit and a rather weak causal effect from inflation to budget deficit. However, there is no short – run causality running from interest rate to budget deficit.

  8. The Dynamic Definition of the Advertising Campaign Budget

    Directory of Open Access Journals (Sweden)

    2017-10-01

    Full Text Available The article is aimed at exploring means for optimizing the budgeting of advertising activity, the optimal distribution of the advertising budget among several products, advertised by a company, and several advertising channels used during the distribution of an advertisement. The current status of the optimizationized budgeting models in the world and in Ukraine was analyzed. The topicality of scientific developments in this direction has been substantiated. The model is based on the non-linear logistics function of the response value of sales for the costs of placement of an advertising message, including market saturation effects and the accumulation of promotional effect. A complex advertising budgeting model has been proposed, which includes the dynamic definition of a budget constraint based on the expected sales return from a byed advertising campaign whose budget is being optimized. The proposed model allows to schedule advertising activities in conditions of uncertainty and rapid change of environment.

    Full Text Available This study aims to analyze the criteria and procedures adopted by companies for determining the budget communication. Specifically, we intend to identify how companies organize the system of deciding the budget and deal with the budget cuts throughout the process of implementation of promotional activities. The data collection involved in-depth interviews conducted with communications professionals from ten companies belonging to the ranking of the 300 largest advertisers in Brazil. As data analysis technique, we have chosen content analysis. The main results showed little or no participation by the communication manager's final decision on the budget area, the lack of criteria to justify budget cuts during the promotional period and the adoption by firms of judgment methods and percentage of sales to determine the budget amount of communication

    2015-01-01

    Demand theory can be applied to analyse how a human or animal consumer changes her selection of commodities within a certain budget in response to changes in price of those commodities. This change in consumption assessed over a range of prices is defined as demand elasticity. Previously, income-compensated and income-uncompensated price changes have been investigated using human and animal consumers, as demand theory predicts different elasticities for both conditions. However, in these studies, demand elasticity was only evaluated over the entirety of choices made from a budget. As compensating budgets changes the number of attainable commodities relative to uncompensated conditions, and thus the number of choices, it remained unclear whether budget compensation has a trivial effect on demand elasticity by simply sampling from a different total number of choices or has a direct effect on consumers’ sequential choice structure. If the budget context independently changes choices between commodities over and above price effects, this should become apparent when demand elasticity is assessed over choice sets of any reasonable size that are matched in choice opportunities between budget conditions. To gain more detailed insight in the sequential choice dynamics underlying differences in demand elasticity between budget conditions, we trained N=8 rat consumers to spend a daily budget by making a number of nosepokes to obtain two liquid commodities under different price regimes, in sessions with and without budget compensation. We confirmed that demand elasticity for both commodities differed between compensated and uncompensated budget conditions, also when the number of choices considered was matched, and showed that these elasticity differences emerge early in the sessions. These differences in demand elasticity were driven by a higher choice rate and an increased reselection bias for the preferred commodity in compensated compared to uncompensated budget

Following different values of budget constraint, bounded ...

  15. How Czech firms deal with operational budgets? – Survey results

    Directory of Open Access Journals (Sweden)

    Boris Popesko

    2017-06-01

    Full Text Available In recent decades, academics and practitioners started a deep discussion about the limitations and perspectives of enterprise budgeting systems. Traditional budgets are frequently criticized due to their inflexibility, weak connection to corporate performance and demand on manager’s time. Recently, we have observed more frequent examples of firms which have undertaken budgeting system transformation and the adoption of modern, flexible and performance-based budgets. In this study, we have studied some trends in the budgeting of Czech firms with a focus on the manager´s behaviour. This paper contributes to the existing knowledge in two fields: Firstly, it summarizes the existing state of the art regarding the budgeting transformation; secondly, it presents the survey results focused on the operational budget utilization and its impact on the manager’s behaviour. Overall, the study presents some findings regarding the impact of an operational budget on the manager’s behaviour. We have tested how frequently situations occur, more specifically those frequently discussed in literature, in a given Czech firm´s budgeting practices.

    1997-12-31

    A three dimensional model for the European boundary layer (the LOTOS model) was used to calculate the budget of ozone and precursors over Europe. For two summer months (July and August) in 1990 the net chemical production of ozone is about 21 Tg/m. By dry deposition 17 Tg/m is lost and transport accounts for a net export of 4 Tg/m into the free troposphere. Large differences in chemical ozone production occur for different regions in Europe. Though the ozone efficiency in terms of ozone produced per NO{sub x} molecule oxidised is much lower in western Europe than elsewhere in Europe the ozone chemically produced per unit area is the highest in western Europe due to the high NO{sub x} emission in this region.

Status of economic development and the income level of population in the regions of Ukraine has been analyzed, characteristics of decentralization, as well as its preliminary outcome, have been described. Attention is focused on positive points in the development of regions in which the united territorial communities have been formed. It has been proposed to raise the mass awareness of population in the regions of Ukraine about the substance of the reform and its objectives, to establish a body of financial control for local councils, and to arrange computer monitoring of the flow of financial resources of the territorial communities along with periodic coverage of its results in the local media in order to increase the transparency of costs management.

  1. Health needs, budget cuts & military spending.

    Science.gov (United States)

    1991-01-01

    A healthy, well-fed, educated populace is synonymous with a prospering economy. Yet, when planning their budgets, governments tend to emphasize infrastructural/industrial projects and defence rather than investing in health, education and other social programmes to eliminate the widespread poverty and high mortality of its population, which would assure a more promising future in the long-term. As citizens, nurses are responsible for initiating and supporting action to meet the health and social needs of the public. And in keeping with ICN's 1989 resolution on nuclear war, INR presents some facts on social and defence spending to show how health needs are often being deprived by emphasis on others sectors, particularly defence. The aim is "to encourage nurses to critically appraise expenditure on health and welfare at a national and global level in relation to that spent on conventional and nuclear arms and to assist nurses to develop strategies of action to contribute to international peace."

  2. Atmospheric nitrogen budget in Sahelian dry savannas

    Directory of Open Access Journals (Sweden)

    2010-03-01

    Full Text Available The atmospheric nitrogen budget depends on emission and deposition fluxes both as reduced and oxidized nitrogen compounds. In this study, a first attempt at estimating the Sahel nitrogen budget for the year 2006 is made, through measurements and simulations at three stations from the IDAF network situated in dry savanna ecosystems. Dry deposition fluxes are estimated from measurements of NO2, HNO3 and NH3 gaseous concentrations and from simulated dry deposition velocities, and wet deposition fluxes are calculated from NH4+ and NO3 concentrations in samples of rain. Emission fluxes are estimated including biogenic emission of NO from soils (an Artificial Neural Network module has been inserted into the ISBA-SURFEX surface model, emission of NOx and NH3 from domestic fires and biomass burning, and volatilization of NH3 from animal excreta. Uncertainties are calculated for each contribution of the budget.

    This study uses original and unique data from remote and hardly-ever-explored regions.The monthly evolution of oxidized N compounds shows that emission and deposition increase at the beginning of the rainy season because of large emissions of biogenic NO (pulse events. Emission of oxidized compounds is dominated by biogenic emission from soils (domestic fires and biomass burning of oxidized compounds account for 0 to 13% at the most at the annual scale, depending on the station, whereas emission of NH3 is dominated by the process of volatilization from soils. At the annual scale, the average gaseous dry deposition accounts for 47% of the total estimated deposition flux, for both oxidized and reduced compounds. The average estimated wet plus dry deposition flux in dry savanna ecosystems is 7.5±1.8 kgN ha−1 yr−1, with approximately 30% attributed to oxidized compounds, and the rest attributed

    Closing the global water and energy budgets has been an elusive Global Energy and Water-cycle Experiment (GEWEX) goal. It has been difficult to gather many of the needed global water and energy variables and processes, although, because of GEWEX, we now have globally gridded observational estimates for precipitation and radiation and many other relevant variables such as clouds and aerosols. Still, constrained models are required to fill in many of the process and variable gaps. At least there are now several atmospheric reanalyses ranging from the early National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR) and NCEP/Department of Energy (DOE) reanalyses to the more recent ERA40 and JRA-25 reanalyses. Atmospheric constraints include requirements that the models state variables remain close to in situ observations or observed satellite radiances. This is usually done by making short-term forecasts from an analyzed initial state; these short-term forecasts provide the next guess, which is corrected by comparison to available observations. While this analysis procedure is likely to result in useful global descriptions of atmospheric temperature, wind and humidity, there is no guarantee that relevant hydroclimate processes like precipitation, which we can observe and evaluate, and evaporation over land, which we cannot, have similar verisimilitude. Alternatively, the Global Land Data Assimilation System (GLDAS), drives uncoupled land surface models with precipitation, surface solar radiation, and surface meteorology (from bias-corrected reanalyses during the study period) to simulate terrestrial states and surface fluxes. Further constraints are made when a tuned water balance model is used to characterize the global runoff observational estimates. We use this disparate mix of observational estimates, reanalyses, GLDAS and calibrated water balance simulations to try to characterize and close global and terrestrial atmospheric

  2. Execution of local budgets in 2014: tension is not decreasing

    Full Text Available Vladimir Putin’s “May decrees” have received the status of a national goal. On the background of decreasing economic performance exacerbated by external shocks, the implementation of these decrees has become a heavy burden for regional budgets without an adequate financial support from the federal budget. As a result, almost every Russian region has suffered losses by the end of 2014. The fallacy of the ongoing course of budget policy has long been criticized by many leading scholars and experts; moreover, they proposed positive recommendations on the development of alternative policies. Unfortunately, the results of 2014 prove that the RF Government has not abandoned the policy of budget consolidation. On the contrary, gratuitous financial assistance to the regions is actively transformed into debt financing in the form of budget loans. However, the regional authorities can rely on this quasi-support, which is a temporary factor, only provided that the budget is deficit-free and at the expense of abandonment of spending on economic development and on the improvement of welfare of the population. The results of the analysis of the facts indicate that the budget-related problems of the regions, arising largely from the inefficient federal budget policy, have reached the critical level. One fourth of the subjects that had a predominant share of market debt turned out to be in a pre-default state. The breakdown of public finances has affected the most prosperous regions, which is contrary to the paradigm of sustainable regional development. The regions entered the crisis of 2014 with huge debt and budget deficit; the situation was not so grave during the financial and economic crisis of 2009. In terms of the upcoming 10% cut of federal budget expenditures [5], the subjects of the Russian Federation can hardly expect an increase in financial support. They will obviously have to adapt their budgets to the changing economic situation. But in

    Full Text Available Accurate assessments of anthropogenic carbon dioxide (CO2 emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere is important to better understand the global carbon cycle, support the climate policy process, and project future climate change. Present-day analysis requires the combination of a range of data, algorithms, statistics and model estimates and their interpretation by a broad scientific community. Here we describe datasets and a methodology developed by the global carbon cycle science community to quantify all major components of the global carbon budget, including their uncertainties. We discuss changes compared to previous estimates, consistency within and among components, and methodology and data limitations. CO2 emissions from fossil fuel combustion and cement production (EFF are based on energy statistics, while emissions from Land-Use Change (ELUC, including deforestation, are based on combined evidence from land cover change data, fire activity in regions undergoing deforestation, and models. The global atmospheric CO2 concentration is measured directly and its rate of growth (GATM is computed from the concentration. The mean ocean CO2 sink (SOCEAN is based on observations from the 1990s, while the annual anomalies and trends are estimated with ocean models. Finally, the global residual terrestrial CO2 sink (SLAND is estimated by the difference of the other terms. For the last decade available (2002–2011, EFF was 8.3 ± 0.4 PgC yr−1, ELUC 1.0 ± 0.5 PgC yr−1, GATM 4.3 ± 0.1PgC yr−1, SOCEAN 2.5 ± 0.5 PgC yr−1, and SLAND 2.6 ± 0.8 PgC yr−1. For year 2011 alone, EFF was 9.5 ± 0.5 PgC yr−1, 3.0 percent above 2010, reflecting a continued trend in these emissions; ELUC was 0.9 ± 0.5 PgC yr−1, approximately constant throughout the decade; GATM was 3.6 ± 0.2 PgC yr−1, SOCEAN was 2.7 ± 0.5 PgC yr−1, and SLAND was 4.1 ± 0.9 PgC yr−1. GATM was low in 2011

  4. The Surface Energy Budget in Urban Environments

    2011-12-01

    Urban heat islands (UHIs) occur when urban and suburban areas experience elevated temperatures relative to their rural surroundings because of differences in vegetation cover, buildings and other development, and infrastructure. Most cities in the United States are warming at twice the rate of the outlying rural areas and the planet as a whole. This difference in temperature is proportional to the size of the city and can be in excess of 2-5°C during the daytime and as much as 10°C at night. UHIs can exacerbate the warming during heat waves and play a role in additional heat-related mortality, an increase in tropospheric ozone, and economic losses that total in the billions of dollars from excess energy consumption. Many cities are experimenting with strategies to reduce urban warming. A number of mitigation strategies involve manipulating the surface energy budget to either reduce the amount of solar radiation absorbed at the surface or offset absorbed energy through latent cooling. Options include using building materials with different properties of reflectivity and emissivity, increasing the reflectivity of parking lots, covering roofs with vegetation, and increasing the amount of vegetation overall through tree planting or increasing green space. The goal of the Islands in the Sun project is to understand the formation and behavior of urban heat islands and to mitigate their effects through sensible city engineering and design practices. Methods include analysis of global remotely sensed datasets, the development of a reduced-complexity urban model, and evaluation of measurements made in the Twin Cities Metropolitan Area (TCMA). The TCMA is a 7,700 square kilometer urban and suburban region located in east central Minnesota that includes the two cities of Minneapolis and Saint Paul. Mitigation of the UHI in northern latitude cities, such as the TCMA, is a challenge because (1) residents in more northerly cities are more likely to suffer heat-related illness

  5. Soil erosion and the global carbon budget.

    Science.gov (United States)

    Lal, R

    2003-07-01

    Soil erosion is the most widespread form of soil degradation. Land area globally affected by erosion is 1094 million ha (Mha) by water erosion, of which 751 Mha is severely affected, and 549 Mha by wind erosion, of which 296 Mha is severely affected. Whereas the effects of erosion on productivity and non-point source pollution are widely recognized, those on the C dynamics and attendant emission of greenhouse gases (GHGs) are not. Despite its global significance, erosion-induced carbon (C) emission into the atmosphere remains misunderstood and an unquantified component of the global carbon budget. Soil erosion is a four-stage process involving detachment, breakdown, transport/redistribution and deposition of sediments. The soil organic carbon (SOC) pool is influenced during all four stages. Being a selective process, erosion preferentially removes the light organic fraction of a low density of erosion causes a severe depletion of the SOC pool on eroded compared with uneroded or slightly eroded soils. In addition, the SOC redistributed over the landscape or deposited in depressional sites may be prone to mineralization because of breakdown of aggregates leading to exposure of hitherto encapsulated C to microbial processes among other reasons. Depending on the delivery ratio or the fraction of the sediment delivered to the river system, gross erosion by water may be 75 billion Mg, of which 15-20 billion Mg are transported by the rivers into the aquatic ecosystems and eventually into the ocean. The amount of total C displaced by erosion on the earth, assuming a delivery ratio of 10% and SOC content of 2-3%, may be 4.0-6.0 Pg/year. With 20% emission due to mineralization of the displaced C, erosion-induced emission may be 0.8-1.2 Pg C/year on the earth. Thus, soil erosion has a strong impact on the global C cycle and this component must be considered while assessing the global C budget. Adoption of conservation-effective measures may reduce the risks of C emission and

    Radiation Budget Instrument (RBI) will be one of five instruments flying aboard the JPSS-2 spacecraft, a polar-orbiting sun-synchronous satellite in Low Earth Orbit. RBI is a passive remote sensing instrument that will follow the successful legacy of the Clouds and Earth's Radiant Energy System (CERES) instruments to make measurement of Earth's short and longwave radiation budget. The goal of RBI is to provide an independent measurement of the broadband reflected solar radiance and Earth's emitted thermal radiance by using three spectral bands (Shortwave, Longwave, and Total) that will have the same overlapped point spread function (PSF) footprint on Earth. To ensure precise NIST-traceable calibration in space the RBI sensor is designed to use a visible calibration target (VCT), a solar calibration target (SCT), and an infrared calibration target (ICT) containing phase change cells (PCC) to enable on-board temperature calibration. The VCT is a thermally controlled integrating sphere with space grade Spectralon covering the inner surface. Two sides of the sphere will have fiber-coupled laser diodes in the UV to IR wavelength region. An electrical substitution radiometer on the integrating sphere will monitor the long term stability of the sources and the possible degradation of the Spectralon in space. In addition the radiometric calibration operations will use the Spectralon diffusers of the SCT to provide accurate measurements of Solar degradation. All those stable on-orbit references will ensure that calibration stability is maintained over the RBI sensor lifetime. For the preflight calibration the RBI will view five calibration sources - two integrating spheres and three CrIS (Cross-track Infrared Sounder ) -like blackbodies whose outputs will be validated with NIST calibration approach. Thermopile are the selected detectors for the RBI. The sensor has a requirement to perform lunar calibration in addition to solar calibration in space in a way similar to CERES

    Full Text Available This study asks how and why a local government settings budget. It aims to deliver an understanding on how a government entity perceives that budget is important element to manage public expenditures. It uses the S local government in Indonesia as a case study. This study applies Institutional Logics Theory as a theoretical framework in order to analyze data. Data is collected by interviewing seven key persons who directly involves in budgeting process. This research shows that the budgeting process includes determining the purposes of annual budget, setting up planned programs and actvities, determining the amount of revenue that will be collected, allocating resources to expenditures and setting up standar pricing. Some important points in the budgeting process are identified. Those are considering political aspect to determine local tax rate, focusing on competition with other local governments, fulfilling the political promise of local government leader to the constituents, involving community to determine planned program and activities, and allocating resources based on community basic needs. This study concludes that those points develop the institutional logics of politic and managerial in budget setting process.

  8. Centralization versus Delegation in an Experimental Capital Budgeting Setting

    Directory of Open Access Journals (Sweden)

    Markus C. Arnold

    2011-04-01

    Full Text Available In an experiment, we model two stylized facts about capital budgeting practice, budgetary slack creation and delegation of decision-making authority. In our setting, under centralization, headquarters announces a budget, the division manager gives a cost report, and headquarters decides on the project. Under delegation, headquarters allocates a budget to the manager, and the manager is authorized to make the investment decision. We argue that the ability of headquarters to commit to a budget moderates the effect of delegation, and we find evidence in favor of our argument as there is an interaction effect of delegation and commitment to budgets. The effects of delegation are particularly strong when budgets are non-binding as delegation serves as a substitute for commitment in this case. This leads to smaller expenditures and to a higher headquarters’ payoff under delegation than under centralization. In contrast, when headquarters can commit to the budget, the descriptive data are consistent with our conjectures about the effects of honesty preferences, but the effects are too small to be significant.

  10. Drivers and predictions of coral reef carbonate budget trajectories.

    Climate change is one of the greatest threats to the long-term maintenance of coral-dominated tropical ecosystems, and has received considerable attention over the past two decades. Coral bleaching and associated mortality events, which are predicted to become more frequent and intense, can alter the balance of different elements that are responsible for coral reef growth and maintenance. The geomorphic impacts of coral mass mortality have received relatively little attention, particularly questions concerning temporal recovery of reef carbonate production and the factors that promote resilience of reef growth potential. Here, we track the biological carbonate budgets of inner Seychelles reefs from 1994 to 2014, spanning the 1998 global bleaching event when these reefs lost more than 90% of coral cover. All 21 reefs had positive budgets in 1994, but in 2005 budgets were predominantly negative. By 2014, carbonate budgets on seven reefs were comparable with 1994, but on all reefs where an ecological regime shift to macroalgal dominance occurred, budgets remained negative through 2014. Reefs with higher massive coral cover, lower macroalgae cover and lower excavating parrotfish biomass in 1994 were more likely to have positive budgets post-bleaching. If mortality of corals from the 2016 bleaching event is as severe as that of 1998, our predictions based on past trends would suggest that six of eight reefs with positive budgets in 2014 would still have positive budgets by 2030. Our results highlight that reef accretion and framework maintenance cannot be assumed from the ecological state alone, and that managers should focus on conserving aspects of coral reefs that support resilient carbonate budgets. © 2017 The Authors.

  11. Role of budget impact in drug reimbursement decisions.

    Science.gov (United States)

    Cohen, Joshua Parsons; Stolk, Elly; Niezen, Maartje

    2008-04-01

    There are three known criteria that underlie drug reimbursement decisions: therapeutic value, cost-effectiveness, and burden of disease. However, evidence from recent reimbursement decisions in several jurisdictions points to residual, unexplained variables, among which is budget impact. Budget impact refers to the total costs that drug reimbursement and use entail with respect to one part of the health care system, pharmaceutical care, or to the entire health care system, taking into account the possible reallocation of resources across budgets or sectors of the health care system. The economic and equity rationale for carrying out budget impact analyses is opportunity cost, or benefits forgone, measured in terms of utility or equitable distribution, by using resources in one way rather than another. In other words, by choosing to draw down the budget in one way, decision makers forgo other opportunities to use the same resources. Under a set of unrealistic assumptions, cost-effectiveness analysis accounts for opportunity cost while conveying to the decision maker the price of maximizing health gains, subject to a budget or resource constraint. However, the underlying assumptions are implausible, particularly in the context of pharmaceutical care. Moreover, budget impact analysis is more useful to the decision maker than cost-effectiveness analysis if the objective is not to maximize health gains subject to a budget or resource constraint, but to reduce variance in health gains. With respect to equitable distribution, budget impact analyses lay bare the individuals or groups who lose out - those who bear the opportunity cost of spending resources in accordance with one decision rule rather than another.

    Energy Technology Data Exchange (ETDEWEB)

    Brainard, James Robert

    2009-10-01

    This report documents The Nambe Pueblo Water Budget and Water Forecasting model. The model has been constructed using Powersim Studio (PS), a software package designed to investigate complex systems where flows and accumulations are central to the system. Here PS has been used as a platform for modeling various aspects of Nambe Pueblo's current and future water use. The model contains three major components, the Water Forecast Component, Irrigation Scheduling Component, and the Reservoir Model Component. In each of the components, the user can change variables to investigate the impacts of water management scenarios on future water use. The Water Forecast Component includes forecasting for industrial, commercial, and livestock use. Domestic demand is also forecasted based on user specified current population, population growth rates, and per capita water consumption. Irrigation efficiencies are quantified in the Irrigated Agriculture component using critical information concerning diversion rates, acreages, ditch dimensions and seepage rates. Results from this section are used in the Water Demand Forecast, Irrigation Scheduling, and the Reservoir Model components. The Reservoir Component contains two sections, (1) Storage and Inflow Accumulations by Categories and (2) Release, Diversion and Shortages. Results from both sections are derived from the calibrated Nambe Reservoir model where historic, pre-dam or above dam USGS stream flow data is fed into the model and releases are calculated.

  13. The carbon budget of Mono Lake

    Science.gov (United States)

    Oxburgh, Rachel; Broecker, Wallace S.; Wanninkhof, Richard H.

    1991-12-01

    Radiocarbon measurements suggest that 14C-free carbon enters from beneath Mono Lake at a rate of about 1 mol/m2/yr. An input of this magnitude should be manifested in the inorganic carbon budget of the lake and with this in mind we have devised a model to reconstruct the evolution of the partial pressure of CO2 (pCO2) over the past 150 years. This encompasses a period (1945 to present) during which major diversions of source waters via the Los Angeles aqueduct have been in effect, significantly increasing the salinity of the lake and hence its pCO2. The model has been constrained by experimental characterization of the carbonate chemistry of the lake water, by the temperature dependence of pCO2 for the lake water, and by pCO2 measurements made on the lake water in 1966, 1969,1981, and 1989. Our calculations suggest that prior to 1945 the pCO2 of Mono Lake water was about 1.3 times the atmospheric value. To produce this excess, an input of CO2 of about 3.3 mol/m2/yr is required. Volcanic activity beneath the lake is a probable source of this input.

    Zhou, Daniel K.; Larar, Allen M.; Liu, Xu; Smith, William L.; Strow, L. Larrabee; Yang, Ping

    2011-01-01

    The ultraspectral infrared radiances obtained from satellite observations provide atmospheric, surface, and/or cloud information. The intent of the measurement of the thermodynamic state is the initialization of weather and climate models. Great effort has been given to retrieving and validating these atmospheric, surface, and/or cloud properties. Error Consistency Analysis Scheme (ECAS), through fast radiative transfer model (RTM) forward and inverse calculations, has been developed to estimate the error budget in terms of absolute and standard deviation of differences in both spectral radiance and retrieved geophysical parameter domains. The retrieval error is assessed through ECAS without assistance of other independent measurements such as radiosonde data. ECAS re-evaluates instrument random noise, and establishes the link between radiometric accuracy and retrieved geophysical parameter accuracy. ECAS can be applied to measurements of any ultraspectral instrument and any retrieval scheme with associated RTM. In this paper, ECAS is described and demonstration is made with the measurements of the METOP-A satellite Infrared Atmospheric Sounding Interferometer (IASI)..

    2013-01-01

    Performance of asymmetric-type MWPC-s are presented. In this structure, referred to as Close Cathode Chamber in an earlier study, the material budget is significantly reduced on one hand by the elimination of external support frame, on the other hand by thin detector walls. In this paper it is demonstrated that the outline is compatible with large size detectors (1 m wire length), maintaining mechanical and operation stability, with total weight of 3 kg (including support structure) for a half square meter surface. The detection efficiency and response time is shown to be sufficient for L0 triggering in the ALICE VHMPID layout. Reduced sensitivity to cathode deformations (due to internal overpressure as mechanical strain) is directly demonstrated. On small sized chambers, improvement of position resolution with analog readout is evaluated, reaching 0.09 mm RMS with 2 mm wide cathode segments. Simulation results on signal time evolutions are presented. With the above studies, comparison of classical MWPC-s and the Close Cathode Chamber design is performed in all major aspects.

  16. A vorticity budget for the Gulf Stream

    Science.gov (United States)

    Le Bras, Isabela; Toole, John

    2017-04-01

    We develop a depth-averaged vorticity budget framework to diagnose the dynamical balance of the Gulf Stream, and apply this framework to observations and the ECCO state estimate (Wunsch and Heimbach 2013) above the thermocline in the subtropical North Atlantic. Using the hydrographic and ADCP data along the WOCE/CLIVAR section A22 and a variety of wind stress data products, we find that the advective vorticity flux out of the western region is on the same order as the wind stress forcing over the eastern portion of the gyre. This is consistent with a large-scale balance between a negative source of vorticity from wind stress forcing and a positive source of vorticity in the western region. Additionally, the form of the vorticity flux indicates that the Gulf Stream has a significant inertial component. In the ECCO state estimate, we diagnose a seasonal cycle in advective vorticity flux across a meridional section associated with seasonal fluctuations in Gulf Stream transport. This vorticity flux is forced by wind stress over the eastern subtropical North Atlantic and balanced by lateral friction with the western boundary. The lateral friction in ECCO is a necessary parameterization of smaller scale processes that occur in the real ocean, and quantifying these remains an open and interesting question. This simplified framework provides a means to interpret large scale ocean dynamics. In our application, it points to wind stress forcing over the subtropical North Altantic as an important regulator of the Gulf Stream and hence the climate system.

    The goal of this study is to study optimized satellite configurations for observation of the radiation balance of the earth. We present a literature survey of earth radiation budget missions and instruments. We develop a parametric tool to simulate realistic multiple satellite mission scenarios. This tool is a modular computer program which models satellite orbits and scanning operation. We use Meteosat data sampled at three hour intervals as a database to simulate atmospheric scenes. Input variables are satellite equatorial crossing time and instrument characteristics. Regional, zonal and global monthly averages of shortwave and longwave fluxes for an ideal observing system and several realistic satellite scenarios are produced. Comparisons show that the three satellite combinations which have equatorial crossing times at midmorning, noon and midafternoon provide the best shortwave monitoring. Crossing times near sunrise and sunset should be avoided for the shortwave. Longwave diurnal models are necessary over and surfaces and cloudy regions, if there are only two measurements made during daylight hours. We have found in the shortwave inversion comparison that at least 15% of the monthly regional errors can be attributed to the shortwave anisotropic models used. (orig.) 68 refs.

    Full Text Available Introduction One of the main targets of planners, decision makers and governments is increasing society health with promotion and production of suitable and healthy food. One of the basic commodities that have important role in satisfaction of required human food is milk. So, some part of government and producer healthy budget allocate to milk consumption promotion by using generic advertising. If effectiveness of advertising budget on profitability is more, producer will have more willing to spend for advertising. Determination of optimal generic advertising budget is one of important problem in managerial decision making in producing firm as well as increase in consumption and profit and decrease in wasting and non-optimality of budget. Materials and Methods: In this study, optimal generic advertising budget intensity index (advertising budget share of production cost was estimated under two different scenarios by using equilibrium replacement model. In equilibrium replacement model, producer surplus are maximized in respect to generic advertising in retail level. According to market where two levels of farm and processing before retail exist and there is trade in farm and retail level, we present different models. Fixed and variable proportion hypothesis is another one. Finally, eight relations are presented for determination of milk generic advertising optimum budget. So, we use data from several resources such as previous studies, national (Iran Static center and international institute (Fao formal data and own estimation. Because there are several estimations in previous studies, we identify some scenarios (in two general scenarios for calculation of milk generic advertising optimum budget. Results and Discussion: Estimation of milk generic advertising optimum budget in scenario 1 shows that in case of one market level, fixed supplies and no trade, optimum budget is 0.4672539 percent. In case of one market level and no trade, optimum

    Operational analyses and retrospective-analyses provide all the physical terms of mater and energy budgets, guided by the assimilation of atmospheric observations. However, there is significant reliance on the numerical models, and so, uncertainty in the budget terms is always present. Here, we use a recently developed data set consisting of a mix of 10 analyses (both operational and retrospective) to quantify the uncertainty of analyzed water and energy budget terms for GEWEX continental-scale regions, following the evaluation of Dr. John Roads using individual reanalyses data sets.

  3. Why budget accountability fails? The elusive links between parliaments and audit agencies in the oversight of the budget

    Directory of Open Access Journals (Sweden)

    CARLOS SANTISO

    2015-09-01

    Full Text Available ABSTRACTParliaments and audit agencies have critical and complementary roles in the oversight of the budget and the enforcement of government accountability. Yet, the nexus between parliaments and audit agencies is one of the weakest links in the accountability chain, generating an accountability gap in the budget process. This articles analyses the interactions between parliaments and audit agencies in the oversight of government finances during the latter stages of the budget process. Using proxies to evaluate the quality of those linkages, such as the follow-up to audit findings and the discharge of government, it shows important dysfunctions in the interactions between parliaments and audit agencies due to a combination of technical capacity constraints and political economy disincentives. It suggests that the effective functioning of the system of checks and balances in public budgeting critically hinges on the agility of the linkages between accountability institutions. As such, the failure of budget accountability is due to systemic dysfunctions in the systems of accountability, rather than the failure of an individual accountability institution acting in isolation. In addition, the effectiveness of the horizontal accountability architecture depends on the political economy incentives shaping the budget process, which are generated by the interactions between the choice of institutional design and budget rules, with the degree of political competition and electoral rules.

  19. Gender inequality in Russia: the perspective of participatory gender budgeting.

    Science.gov (United States)

    Zakirova, Venera

    2014-11-01

    Gender-based discrimination is found in all economies in the world. Women's unpaid work accounts for about half of the world GDP, yet women remain under-valued and under-represented in national policies worldwide. The question of gender budgeting and citizens' participation in budgeting and governance processes has gained attention in recent years, but Russia is far from implementing these. Instead, blindness to gender issues dominates in national strategies and budgets. This paper explores these issues and looks in-depth at them in the decentralisation process in Bashkortostan, a central Russian republic. Civil society institutions whose role is to strengthen the links between government, civil society and the community in Bashkortostan, such as Public Chambers and Municipalities, lack the capacity to introduce participatory gender budgeting. As a result, no systematic participatory planning, let alone planning that is gender-sensitive, has taken place there. Copyright © 2014 Reproductive Health Matters. Published by Elsevier Ltd.

The aim of this study was to identify thepopularity and extent of usage of various techniques for capital budget evaluation, investmentappraisal, risk analysis, and management science. The current study was comparedwith a similar survey conducted in 1994 to establish the changes in the capital budgetingevaluation practices of contracting firms over time. The results indicate that there was ageneral increase in the popularity and extent of usage in certain capital budget evaluationtechniques such as “best/worst estimate” and “formal financial evaluation”. In addition,the evaluation techniques examined were fitted into a discriminant function analysis (DFA,and a model has been developed which allows contracting firms to be classified accordingto their predominant characteristics in capital budget evaluation.

  5. The Role of Budget Airlines in the Air Transport Market

    Directory of Open Access Journals (Sweden)

    Panasiuk Irina P.

    2017-05-01

    Full Text Available The contemporary air transport market has been considered and analyzed, key aspects of the emergence of budget airlines (low-cost in the air transport market have been highlighted. The main factors of influence on their functioning and international distribution have been allocated. On exploring the air transport market, it can be argued that low-cost airlines are gaining speed and spreading all around the world. This system was developed specifically for budget tourists and is particularly popular among students. Budget airlines are a profitable alternative to expensive airfares. As a rule, low-cost airlines refuse most traditional services to reduce the cost of transporting passengers, and hence the prices of flights. In the current phase of operation of the budget airlines, it is particularly necessary to study the reasons for such charity and the efficiency factor in providing cheap airfares. In spite of the tempting offer, there are some nuances that are subject of research.

  6. Accuracy of Atmospheric Energy Budgets from Analyses.

    Trenberth, Kevin E.; Stepaniak, David P.; Caron, Julie M.

    2002-12-01

    Issues relevant to achieving an accuracy of better than 10 W m2 on 250-km scales for monthly means in the atmospheric energy balance are explored from the standpoint of the formulation and computational procedures using the National Centers for Environmental Prediction-National Center for Atmospheric Research (NCEP-NCAR, hereafter referred to as NCEP) and the European Centre for Medium-Range Weather Forecasts (ECMWF) reanalyses. The focus is on the vertically integrated energy components, their monthly tendencies, transports, and divergences, using the most accurate computations in model and pressure coordinates. Approximate equations have often been used previously; although relatively small compared with the moist static energy, kinetic energy transports should be taken into account, as divergences can exceed several tens of watts per square meter. Changes in energy storage terms over a month are not negligible, as they are typically over 25 W m2 in storm track regions. Transports of energy are meaningful only if the mass budget is closed.Typical magnitudes of the divergence of sensible heat and potential energy are very large (several hundred watts per square meter), but partly cancel when combined as dry static energy, reflecting the role of isentropic flow. The latent energy and sensible heat contributions are strongly positively correlated because of the dominance of low-level flow, and the latent energy divergence also cancels a large component of the dry static energy divergence, leaving a modest residual. This arises from the dominance of moist adiabatic processes in the Tropics and subtropics as the net divergent transports depend on temperature departures in the vertical from the saturated adiabatic lapse rate and their covariability with wind. Careful numerical treatments are required or else small errors in the large terms that should cancel can be amplified. Common assumptions that diagnostics can be computed on model terrain-following coordinates

    Full Text Available This study aims to interpret the meaning of budget on one of the StateOwned Enterprises (SOEs to minimize conflict between principal and agent. Analysis is done using symbolic interactionism method in interpretive paradigm. Data collection is conducted using in-depth interviews with informants who are very familiar with budgeting in PT Perkebunan Nusantara (PTPN. The results of this study reveal that budgeting process involves the interaction and action between the principal and the agent based on their own experiences in preparing the budget. Decision making is sorely needed, especially in a condition where an individual is able to free himself from the crisis called epiphany. Epiphany is a moment of experience that makes an impression on one’s life so as to form a character is called epiphany. It could be said that epiphany is the most critical moment ever experienced by someone that cannot be forgotten(Denzim, 1989Social fact describes that a capitalistic company ownership thinks of itself with the purpose of fulfilling personal desires and prosperity, so in implementing budget preparation consisting of the symbol of numbers, it is always covered by passion of greed. Conflict of interest is very noticeable when the preparation and adoption of the budget is filled with a variety of interests. Regulatory system is becoming part of legitimate stage of budgeting that has become the elements of capitalist company ownership that eventually reap capitalist values in the accounting information, in which the decisions and the economic actions are also based on the capitalist values. The implication of this research is expected to provide practical recommendations to the good cooperation between the agent and principal in preparing the budget.

    Full Text Available The financial budget is a statement about what is to be achieved at a future date and on the other drew up the method by which it shall achieve the financial goals. This has two dimensions, a time frame and level of aggregation, and most of the decisions involve long lead times, which means that they require much time to implant. In most tourist facilities practice indicates that the making of the budget shows a deviation of up to 45 % on the obtained real. From the above it follows that these assumptions are carried out under conditions of considerable uncertainty as it becomes necessary to use methods that take into account financial planning these conditions result in uncertainty and minimize the deviations are not substantiated. There are different methods to prepare the budget, which have advantages and disadvantages. In this research intends to use the preparation of budgets, fuzzy linear regression,  which consists in finding two regression lines that contain all the information and that the distance between them is minimal, in order to obtain a range of budget as a basis for future estimation. The two lines are determined by linear programming and its solution is used for the computer system LINDO. Preliminary testing in a hotel installation of the province Santiago de Cuba, are closer to actual budget execution in the years 2007 and 2008 compared with the traditional method by 14 and 18 % less compared to the traditional method.

Attention on the problems of imbalance and deficiency trends accumulation of public debt has been focused. The detailed analysis of the budget deficit of the European community to further research the main problems of fiscal security has been carried out. The formation of the concept of budget policy should include long-term and medium-term priorities of the state priorities areas have been concluded. Budget policy on public debt must deal with interrelated issues of debt bondage and effective use of public credit, promote economic growth with respect safe level and structure of public debt have been emphasized by author. Debt policy as part of fiscal policy under certain conditions can be a powerful tool to intensify investment and innovation processes in society, promote economic and social development. The reorientation of fiscal policy to address current problems through debt and use it as the basis of investment and innovation development provides an effective public debt management is designed to reduce state budget expenditures on its servicing and repayment, optimizing the scope and structure of debt according to economic growth.

    Full Text Available This paper discusses the EU budget aiming at casting light on the relationship between political and economic matters and on the importance that they function as a mechanism. Somehow the budget could be compared to a barometer showing the political pressure and the level of integration inside the European Union. Discussing the structure of the budget, where the EU money come from and how are the funds distributed afterwards, and also referring to important moments in the historical development of the European Union’s budget, the paper emphasizes the same idea of financial matters strong related to the political choices. It argues also, by describing the complexity of the budgetary procedure and the importance of financial control, that the budget is an important interplay between actors, is an important balance of power trying to reach equilibrium and efficiency. The paper also reviews the main issues of the present budgetary debates, the positions taken by European actors, counting their losses and gains, and to which extent their choices are more a national concern or following the European interest, aiming at presenting the actual state of the European Union taking into account both the economic and the political integration. The budget being one of the key elements forming the structure of the big edifice, the European Union, it is of great importance when discussing budgetary matters to have in mind the present context as a whole, determined by issues like the failure of the summit for setting a new budgetary framework, or the rejection of the European Constitution by the citizens of two of its founding members. Though, it is important when discussing the budget, economical matters to put them in a political context and also to see them in the present context.

    In the present study the economic, political and institutional sources of budgets deficits are analysed for two regions South Asia and ASEAN countries for the period 1984 to 2010. The results reveal that high income, rising inflation and large budget to GDP ratio are associated with budget instability, where as a strong inertia in budget deficit volatility exists. The exposure of more external shocks make the budget deficit more volatile, however, countries with high population growth have le...

    Estimation of the major components of the hydrologic budget is important for determining the impacts on the water supply and quality of either planned or proposed land management projects, vegetative changes, groundwater withdrawals, and reservoir management practices and plans. As acquisition of field data is costly and time consuming, models have been created to test various land use practices and their concomitant effects on the hydrologic budget of watersheds. To simulate such management scenarios realistically, a model should be able to simulate the individual components of the hydrologic budget. The main objective of this study is to perform the SWAT2012 model for estimation of hydrological budget in six subbasin of Persian Gulf watershed; Golgol, Baghan, Marghab Shekastian, Tangebirim and Daragah, which are located in south and south west of Iran during 1991-2009. In order to evaluate the performance of the model, hydrological data, soil map, land use map and digital elevation model (DEM) are obtained and prepared for each catchment to run the model. SWAT-CUP with SUFI2 program was used for simulation, uncertainty and validation with 95 Percent Prediction Uncertainty. Coefficient of determination ( R 2) and Nash-Sutcliffe coefficient (NS) were used for evaluation of the model simulation results. Comparison of measured and predicted values demonstrated that each component of the model gave reasonable output and that the interaction among components was realistic. The study has produced a technique with reliable capability for annual and monthly water budget components in Persian Gulf watershed.

  11. Global volcanic emissions: budgets, plume chemistry and impacts

    Over the past few decades our understanding of global volcanic degassing budgets, plume chemistry and the impacts of volcanic emissions on our atmosphere and environment has been revolutionized. Global volcanic emissions budgets are needed if we are to make effective use of regional and global atmospheric models in order to understand the consequences of volcanic degassing on global environmental evolution. Traditionally volcanic SO2 budgets have been the best constrained but recent efforts have seen improvements in the quantification of the budgets of other environmentally important chemical species such as CO2, the halogens (including Br and I) and trace metals (including measurements relevant to trace metal atmospheric lifetimes and bioavailability). Recent measurements of reactive trace gas species in volcanic plumes have offered intriguing hints at the chemistry occurring in the hot environment at volcanic vents and during electrical discharges in ash-rich volcanic plumes. These reactive trace species have important consequences for gas plume chemistry and impacts, for example, in terms of the global fixed nitrogen budget, volcanically induced ozone destruction and particle fluxes to the atmosphere. Volcanically initiated atmospheric chemistry was likely to have been particularly important before biological (and latterly anthropogenic) processes started to dominate many geochemical cycles, with important consequences in terms of the evolution of the nitrogen cycle and the role of particles in modulating the Earth's climate. There are still many challenges and open questions to be addressed in this fascinating area of science.

  12. Behavior-Based Budget Management Using Predictive Analytics

    2013-03-01

    Historically, the mechanisms to perform forecasting have primarily used two common factors as a basis for future predictions: time and money. While time and money are very important aspects of determining future budgetary spend patterns, organizations represent a complex system of unique individuals with a myriad of associated behaviors and all of these behaviors have bearing on how budget is utilized. When looking to forecasted budgets, it becomes a guessing game about how budget managers will behave under a given set of conditions. This becomes relatively messy when human nature is introduced, as different managers will react very differently under similar circumstances. While one manager becomes ultra conservative during periods of financial austerity, another might be un-phased and continue to spend as they have in the past. Both might revert into a state of budgetary protectionism masking what is truly happening at a budget holder level, in order to keep as much budget and influence as possible while at the same time sacrificing the greater good of the organization. To more accurately predict future outcomes, the models should consider both time and money and other behavioral patterns that have been observed across the organization. The field of predictive analytics is poised to provide the tools and methodologies needed for organizations to do just this: capture and leverage behaviors of the past to predict the future.

  13. The basic thermodynamics of Earth's radiation budget

    greenhouse gases. There simply is not enough thermal energy absorbed by greenhouse gases to have a major effect on global warming. Computer programs used to quantify greenhouse-gas theory overestimate infrared energies because they assume that thermal energy travels in space as waves, for which energy is a function of amplitude squared, and that energies are additive over bandwidth, both properties that are very different from the observed behavior of radiation in the atmosphere. Heat only flows from hot to cold; it cannot flow from a colder layer in the atmosphere to a warmer Earth, as assumed in many radiation budgets (e.g. Wild et al., 2013); you cannot get warmer by standing next to a cold stove. According to Planck's Law, radiation from a body of matter does not have high enough frequencies or amplitudes to warm the same body, as is assumed by greenhouse-gas theory. Warming radiation must come from a warmer body. Detailed observations of global warming, including the recent hiatus, are explained much more directly and clearly by ozone depletion theory, where less ozone in the stratosphere allows more high-energy, solar ultraviolet radiation to reach Earth, cooling the stratosphere, warming the oceans.

    Full Text Available The goal of this work is to design a minimum cost resilient overlay network, where a data network is on top of a transport network. Two major challenges are addressed. On one hand, a single failure in the transport network causes multiple simultaneous failures; on the other, the multicommodity flow must respect integrality. An integer programming formulation is presented to design an overlay, meeting the previous constraints. We prove the problem belongs to the class NP-Hard. Then, a decomposition approach is introduced, where the problem is solved in two steps by means of relaxations of the original formulation. Experiments carried out with real-life instances, coming from the Uruguayan telecommunication operator, show that the approach is competitive with respect to previous metaheuristics, to know, Tabu-Search (TS and Variable Neighborhood Search (VNS. A modest percentage of cost-reduction is achieved in some instances, which means millionaire savings in practice.

  15. Urbanization Process and Variation of Energy Budget of Land Surfaces

    Directory of Open Access Journals (Sweden)

    Ciro Gardi

    Full Text Available Urban areas are increasing at a rate much higher than human population growth in many part of the world; actually more than 73 towns in the world are larger than 1000 km2. The European Environmental Agency indicates an urban area average growth rate, over the last 20 years, of 20%. The urbanization process, and the consequent soil sealing, determines not only the losses of the ecological functions of the soil, but also a variation of the energy budget of land surfaces, that affect the microclimatic conditions (heat islands. The alteration of the energy budget are determined by the variations of albedo and roughness of surfaces, but especially by the net losses of evapotranspirating areas. In the present research we have assessed the variation of Parma territory energy budget, induced by the change in land use over the last 122 years. The urban area increase between 1881 and 2003 was 535%.

  16. Budgeting Issues in the Act on Metropolitan Unions

    Full Text Available Resolved in 2015 the act on metropolitan unions was meant to be a legal instrument with complex character. It included regulations concerning constitution and tasks of the unions and basics of budget management, as well the budgetary procedures. They are not exhaustive regulations and some of them may be even regarded as needless from point of view of correct legislative standards. However, for the metropolitan unions budgeting issues, the regulations have no comprehensive nature and basically they are only an outline of the financial status concept, including budgetary one, of these entities. The metropolitan union's financial law and budgeting position must be therefore shaped using regulations taken from separate laws, especially, the law on public finances and the law on regional accounting chambers.

    A kinetic energy budget analysis of the AVE-SESAME 1 period which coincided with the deadly Red River Valley tornado outbreak is presented. Horizontal flux convergence was found to be the major kinetic energy source to the region, while cross contour destruction was the major sink. Kinetic energy transformations were dominated by processes related to strong jet intrusion into the severe storm area. A kinetic energy budget of the AVE 6 period also is presented. The effects of inherent rawinsonde data errors on widely used basic kinematic parameters, including velocity divergence, vorticity advection, and kinematic vertical motion are described. In addition, an error analysis was performed in terms of the kinetic energy budget equation. Results obtained from downward integration of the continuity equation to obtain kinematic values of vertical motion are described. This alternate procedure shows promising results in severe storm situations.

    Future large astronomical telescopes in space will have architectures that will have complex and demanding requirements to meet the science goals. The Large UV/Optical/IR Surveyor (LUVOIR) mission concept being assessed by the NASA/Goddard Space Flight Center is expected to be 9 to 15 meters in diameter, have a segmented primary mirror and be diffraction limited at a wavelength of 500 nanometers. The optical stability is expected to be in the picometer range for minutes to hours. Architecture studies to support the NASA Science and Technology Definition teams (STDTs) are underway to evaluate systems performance improvements to meet the science goals. To help define the technology needs and assess performance, a first order error budget has been developed. Like the JWST error budget, the error budget includes the active, adaptive and passive elements in spatial and temporal domains. JWST performance is scaled using first order approximations where appropriate and includes technical advances in telescope control.

  20. A Theory of the Perturbed Consumer with General Budgets

    DEFF Research Database (Denmark)

    McFadden, Daniel L; Fosgerau, Mogens

    We consider demand systems for utility-maximizing consumers facing general budget constraints whose utilities are perturbed by additive linear shifts in marginal utilities. Budgets are required to be compact but are not required to be convex. We define demand generating functions (DGF) whose...... subgradients with respect to these perturbations are convex hulls of the utility-maximizing demands. We give necessary as well as sufficient conditions for DGF to be consistent with utility maximization, and establish under quite general conditions that utility-maximizing demands are almost everywhere single......-valued and smooth in their arguments. We also give sufficient conditions for integrability of perturbed demand. Our analysis provides a foundation for applications of consumer theory to problems with nonlinear budget constraints....
