description: Here, the modelling of an inventory system for price and stock reliant demand with the combination of quantity discount and credit limit policy has been presented. Price and stock level are the key sources that always affect the demand of any product. In present study the cost of holding is considered as a time varying function. Vendors usually offer different policies or discounts to attract more customers. Different possible cases for offered trade credit period are discussed in the model. Shortages with partial backlogging are considered here in the development of the model. The different possible cases in this model is exemplified numerically with the help of software Mathematica 11.3 and a sensitivity analysis with respect to distinct system parameters is also presented.

description: This study aims at investigating an optimal resource plan in order to minimize the software costs in the debugging and testing phases. We have proposed a resource allocation model to address testing efforts, imperfect debugging and change-point. We have considered two cases: In the first case, the software debugging cost is kept constant, and in this case, the optimal policy follows a bang-bang structure, which means investing entirely in the testing phase, followed by investing fully in the debugging stage. In the second case, we have taken the debugging cost in quadratic form. We have validated our model with the experimental data, and the results reveal that the presented model is reasonably accurate. We have also discussed the optimal resource allocation problems under certain conditions and examine the parameters’ behavior in the model and obtain the variations in the total cost. This study provides a detailed optimal control theory-based testing resource allocation policy, which is supported by numerical examples.

description: In present climate of competition, each prime company wants to increase the planning of pricing in order to get more profit; controlling the cost of inventories is one of the finest policies of it. The present research study elaborates an order level inventory policy for perishable items where the rate of decay varies with time directly. The holding and ordering costs are taken the functions of time. The policies of optimality and decision rules are developed to optimize the total inventory cost,. The shortages are totally backlogged and allowed. A numerical example is given to explain and verify the study. In order to examine the effect of major parameters on decision-making, a sensitivity analysis is performed. Eventually, conclusions are presented along with some managerial perceptions.

description: In most of the production-based model, the effect of deterioration at initial stage of the production is not assumed even if assumed than considered to be constant, in few productions-based model deteriorations is assumed time-dependent but during initial level of production its effect was not considered. For a product whose life is high this phenomenon is justifying but for those products whose life is very less this is not faring to not assume the effect of deterioration. In the present study, author have considered the effect of deterioration at the initial level of the model and for the rest cycle of the model as well. After a fixed time, a price discount is also offered for partially deteriorated items where a discount rate is offer at the original one, Shortages are not allowed, production is assumed as demand dependent, and demand is assumed as stock dependent where holding cost of the inventory is assumed as a function of time. A numerical example is also discussed.

description: A line g is a transversal to a family F of convex polytopes in 3-dimensional space if it intersects every member of F. If, in addition, g is an isolated point of the space of line transversals to F, we say that F is a pinning of g. We show that any minimal pinning of a line by convex polytopes such that no face of a polytope is coplanar with the line has size at most eight. If, in addition, the polytopes are disjoint, then it has size at most six. We completely characterize configurations of disjoint polytopes that form minimal pinnings of a line.

description: Present paper discusses a two-state retrial queueing model with feedback and balking. If a customer on arrival finds the server free it is served immediately. Else either it joins the retrial orbit as a secondary customer or balks from the system due to impatience. Primary and secondary arrivals both follow Poisson process. If the customer feels unsatisfied after service, it may join the orbit as a feedback customer. Service times follow Exponential distribution. The transient state probabilities for exact number of arrivals and departures when the server is busy or idle are obtained by solving difference-differential equations. Numerical solution is obtained and presented graphically.
Eskimo kinship terminologies
Creators: name: Stevenson, David
Publisher: name: University of British Columbia
Year: 2011

description: Seventeen complete and incomplete Eskimo kinship terminologies are examined and compared with a view to determining and assessing the nature and extent of the reported discrepancies. It is shown that the lack of a standardized orthography for the Eskimo language has contributed to the difficulties of comparing the distribution of terminology. Nuances of the language, especially those relating to the use of different suffixes for 'step', 'adoptive', and 'lesser' are shown to give rise to some of the reported discrepancies. The definitions of Spier and Murdock relating to the 'Eskimo Type' of kinship system and social structure are examined and found to be invalid for the areas for which data are available. It is established that a core of terminological and structural similarity exists between the geographically isolated systems. But the importance of local variables demands that correlations between the kinship system and the associated social structure must be made within the framework of the local economic and ecological factors impinging upon the domestic group. The apparently asymmetrical relationship between-ascending and descending generations is examined within the conceptual framework of the developmental cycle of domestic groups. It is suggested that the specificity of terminology is related to the economic effectivity of the category of relative under discussion. The data available are insufficient for statistical analyses but it is thought that the statistical approach will provide a more coherent picture of the structural and functional inter-relationships between the on-going institutions and that local variations will be shown to have rational bases.

description: An optical transmitter that uses entangled light generated by spontaneous parametric downconversion (SPDC), in conjunction with an optimal quantum-optical receiver (whose implementation is not yet known) is in principle capable of obtaining up to a 6 dB gain in the error-probability exponent over the optimum-reception un-entangled coherent-state lidar to detect the presence of a far-away target subject to entanglement-breaking loss and noise in the free-space link [Lloyd'08, Tan'08]. We present an explicit design of a structured quantum-illumination receiver, which in conjunction with the SPDC transmitter is shown to achieve up to a 3 dB error-exponent advantage over the classical sensor. Apart from being fairly feasible for a proof-of-principle demonstration, this is to our knowledge the first structured design of a quantum-optical sensor for target detection that outperforms the comparable best classical lidar sensor appreciably in a low-brightness, lossy and noisy operating regime.

Year: 2014

description: In 2013, widespread publicity given to the deaths of two women accused of witchcraft in Papua New Guinea (PNG) drew international and national attention to the problem of sorcery and witchcraft accusation–related violence. In the face of mounting pressure to take action, including the national haus krai protest calling for an end to violence against women, the government responded by repealing the Sorcery Act 1971 and creating a new provision in the Criminal Code Act 1974 (Chapter 262). Section 229A of the Criminal Code Act provides that any person who intentionally kills another person on account of an accusation of sorcery is guilty of wilful murder, for which the penalty is death. However, there is growing recognition, both within the government and the wider community, that these problems cannot be solved solely at a legislative level, and must rather involve a holistic response. This In Brief outlines the substance of, and steps leading to, a draft national action plan that was developed in June 2014 to provide a concrete foundation for this holistic response.

description: This paper studies the time-dependent first-in-first-out (FIFO) queuing model with a single intermittently available server and variable-sized bulk arrivals and bulk departures. The time between arrivals, servicing time, and server availability time follows an exponential distribution. The difference-differential equations are used for developing system equations, and the Laplace transforms (L.T.), and inverse transforms are used for the solution. Explicit two-state transient recursive probabilities are obtained for an exact number ofbulk arrivals and bulk departures, and in the end, few particular casesare derived.

description: Full exploitation of the physics potential of a future International Linear Collider will require the use of polarized electron and positron beams. Experiment E166 at the Stanford Linear Accelerator Center (SLAC) has demonstrated a scheme in which an electron beam passes through a helical undulator to generate photons (whose first-harmonic spectrum extended to 7.9MeV) with circular polarization, which are then converted in a thin target to generate longitudinally polarized positrons and electrons. The experiment was carried out with a one-meter-long, 400-period, pulsed helical undulator in the Final Focus Test Beam (FFTB) operated at 46.6GeV. Measurements of the positron polarization have been performed at five positron energies from 4.5 to 7.5MeV. In addition, the electron polarization has been determined at 6.7MeV, and the effect of operating the undulator with a ferrofluid was also investigated. To compare the measurements with expectations, detailed simulations were made with an upgraded version of Geant4 that includes the dominant polarization-dependent interactions of electrons, positrons, and photons with matter. The measurements agree with calculations, corresponding to 80% polarization for positrons near 6MeV and 90% for electrons near 7MeV.

description: The challenge of upgrading the complex industrial systems is basically to cope up with the everincreasing demands of the real world. For the maximum reliability of complex industrial systems, decisions of management depend on experience. This is because the pattern of the chance of success is not easy to predict due to limited and rough available information. Thus, the task of the researchers lies here to increase the operational time of the individual components of a system for maintaining higher system reliability to increase productivity and profit of an organization. In this paper, an optimum choice of the mean time between failure (MTBF), mean time to repair (MTTR), and associated costs in a suitable design unit has been showcased to bring as much efficiency as possible. The motive is to minimize the cost satisfying the availability constraints of the system by using a few recent nature-inspired optimization techniques named Grey Wolf Optimization (GWO) technique and Cuckoo Search Algorithm (CSA). The computational parameters produced to improve the efficiency of the designed system with the application of GWO and CSA techniques, which not only achieve the target of minimum cost but also stand out much competitively in terms of performance. The results obtained by these two algorithms for butter oil processing system are compared and this comparative study shows that the GWO is superior to CSA for this availabilitycost optimization problem of butter oil processing system.

description: The deterministic inventory model for decayed items concerns with reliability process and flexible production rate. The rate of decayed items is assumed to be a two parameters Weibull distribution. In this study, complete backlogging shortages are acceptable and holding cost is taken as linear. Further the influence of inflation has been developed and the model is established with numerically and sensitivity analysis which has been given the impact of parameters and also interpreted through graphically. The system is designed for the producer to validate the model to optimum level.

description: In-situ, device level measurement of thermal mag-noise spectral linewidths in 60nm diameter CPP-GMR spin-valve stacks of IrMn/ref/Cu/free, with reference and free layer of similar CoFe/CoFeGe alloy, are used to simultaneously determine the intrinsic Gilbert damping for both magnetic layers. It is shown that careful alignment at a "magic-angle" between free and reference layer static equilibrium magnetization can allow direct measurement of the broadband intrinsic thermal spectra in the virtual absence of spin-torque effects which otherwise grossly distort the spectral line shapes and require linewidth extrapolations to zero current (which are nonetheless also shown to agree well with the direct method). The experimental magic-angle spectra are shown to be in good qualitative and quantitative agreement with both macrospin calculations and micromagnetic eigenmode analysis. Despite similar composition and thickness, it is repeatedly found that the IrMn exchange pinned reference layer has ten times larger intrinsic Gilbert damping (alpha ~ 0.1) than that of the free-layer (alpha ~ 0.01). It is argued that the large reference layer damping results from strong, off -resonant coupling to to lossy modes of an IrMn/ref couple, rather than commonly invoked two-magnon processes.

description: Reciprocating compressor is one of the critical components in petrochemical, process and gas storage /transportation industry. Due to the dynamic operating conditions, valve failures of the compressors are one of the most frequent failures that causes around 36% of the unplanned shutdowns for reciprocating compressors. For reliable operations of the compressor, a conditionbased fault diagnosis model is proposed in this study. Majority of the existing studies are based on vibration, pressure and other intrusive sensors, which interferes with the system dynamics. Hence, non-intrusive acoustic sensor-based signal analysis technique is tested in this study. Due to the non-stationary nature of the acoustic signal obtained from the working compressor, it is quite difficult to extract fault-specific information. Hence, Minimum Entropy Deconvolution Adjusted (MEDA)-Empirical Mode Decomposition (EMD) approach is proposed for valve-fault diagnosis of reciprocating compressor. After enhancing the impulsiveness of the raw signals with the help of MEDA, a set of IMFs is obtained through EMD method. From this IMF-set, information rich IMF is selected based on the kurtosis value. For extraction of fault related information, two time-domain features (RMS and sample entropy) are used. The results show that MEDA can enhance the signal features effectively which is critical for fault detection. Compared to EMD method, the proposed methodology has shown promising results for inlet and outlet valve-fault diagnosis of reciprocating compressor.

description: Small adjustments in atomic configurations can significantly impact the magnetic properties of matter. Strain, for instance, can alter magnetic anisotropy and enable fine-tuning of magnetism. However, the effects of these changes on nanoscale magnetism remain largely unexplored. In particular, when strain fluctuates at the nanoscale, directly linking structural changes with magnetic behavior poses a substantial challenge. Here, we develop an approach, LA-Ltz-4D-STEM, to map structural information and magnetic fields simultaneously at the nanoscale. This approach opens avenues for an in-depth study of structure-property correlations of magnetic materials at the nanoscale. We applied LA-Ltz-4D-STEM to image strain, atomic packing, and magnetic fields simultaneously in a deformed amorphous ferromagnet with complex strain variations at the nanoscale. An anomalous magnetic configuration near shear bands, which reside in a magnetostatically high-energy state, was observed. By performing pixel-to-pixel correlation of the different physical quantities across a large field of view, a critical aspect for investigating industrial ferromagnetic materials, the magnetic moments were classified into two distinct groups: one influenced by magnetoelastic coupling and the other oriented by competition with magnetostatic energy.

description: In today's era, humans have shifted from the stage of fulfilling their needs to the stage of freedom where they indiscriminately use all the resources. This has increased the concern for protecting our nature and developing sustainable practices. So, an EOQ inventory model is formulated for decaying items with capacity constraint policy where demand is stock-dependent. Shortages are allowed with condition of partial backlogging. The impact of carbon emission is taken on holding cost and deterioration cost. Due to different conditions of storage, the deterioration rate is also different in different warehouses. The main focus of this study is to optimize total cost with carbon emission and total cycle time. An algorithm for the inventory model to find the best output is formulated here. Numerical example with sensitivity is also discussed to show the impact of carbon emission.

description: Latin hypercube design (LHD) is a multi-stratified sampling method, which has been frequently used in sampling-based analysis. To achieve good space-filling quality of LHD, an efficient method, termed local search-based genetic algorithm (LSGA), is proposed in this article for constructing an optimal LHD. LSGA adopts modified order crossover, probabilistic mutation and adaptive selection operators to enrich population diversity and speed up convergence. A local search strategy is also presented in the approach to enhance the search ability. The performance of the proposed method is compared with several established methods in three perspectives, namely space-filling quality, computational efficiency and predictive accuracy of the metamodel. Several numerical experiments with distinct dimensions and numbers of design points are studied, and the results demonstrate that the proposed method performs better than other methods when dealing with LHD construction issues with high dimension and a large number of sampling points.

description: A quantitative understanding of the weak nuclear response is a prerequisite for the computer simulations of astrophysical phenomena like supernov$æ$ explosions and neutron star cooling. In order to reduce the systematic uncertainties associated with the simulations, a consistent framework, able to take into account dynamical correlation effects, is needed to compute neutrino-nucleon and neutrino-nucleus reaction rates. In this paper we describe the many-body theory of the weak nuclear response at low energy regime. We show how to include both short and long correlations effects in a consistent fashion.

description: The fundamental basis of Industry 4.0 is to make the manufacturing sector more productive and autonomous. In the manufacturing sector, practitioners always long for product quality improvement, reducing reworking costs, enhancing first pass yield in production or assembly line, in this regard anomaly detection, is becoming popular and is widely used. With the integration of anomaly detection models and Artificial Intelligence-based condition monitoring systems, industries have attained promising results in achieving these goals. However, it is a highly complex task to extract meaningful information from the large amount of data generated by the manufacturing systems. Hence, in this paper, effective machine-learning-based anomaly detection and prediction model has been proposed. A two-phase model is presented in this study and is validated for abnormality detection in the assembly line of vacuum pumps. In the first phase, a random forest algorithm is used to predict the pump vacuum. Based on the actual and predicted values, the error is computed. Then, EWMA (Exponentially Weighted Moving Average) chart is employed to detect the anomalies. In the second phase of the proposed model, based on the EWMA chart and calculated error, anomaly prediction is done. For better prediction results, statistical features are extracted from the error values and used as input for the second phase. To validate the proposed approach, other machine learning models SVR, Decision Tree, Logistic Regression, KNN and SVC have been compared. A statistical method EWMA chart is also integrated with random forest.

description: In this work we study reliability structures with two common failure criteria under specific agebased preventive maintenance models. The aforementioned systems, which consist of n independent components, fail upon the occurrence of two different scenarios. The theoretical framework for delivering the expected cost rate of such structures is presented in detail, while a variety of numerical outcomes for different choices of the design parameters are also provided and discussed.

description: The trigonal zigzag nanodisk with size $N$ has $N$ localized spins. We investigate its thermodynamical properties with and without external leads. Leads are made of zigzag graphene nanoribbons or ordinary metallic wires. There exists a quasi-phase transition between the quasi-ferromagnet and quasi-paramagnet states, as signaled by a sharp peak in the specific heat and in the susceptability. Lead effects are described by the many-spin Kondo Hamiltonian. A new peak emerges in the specific heat. Furthermore, the band width of free electrons in metallic leads becomes narrower. By investigating the spin-spin correlation it is argued that free electrons in the lead form spin-singlets with electrons in the nanodisk. They are indications of many-spin Kondo effects.

description: Software development techniques have always been in-focus while creating high-quality software. Off late, most software firms have adopted the latest approach of the market“Agile Software Development” to create a superior product. Agile software development allows an incremental and iterative development of the product with close interaction of all the teams on deck. This allows for the efficient utilization of the available resources to satisfy the demands of the end consumer. In the current proposal, a mathematical model has been created which allows optimal allocation of the limited developmental resources among the various sprint cycles and modules. Optimization tools have been used to determine this optimal distribution of resources. The proposed model has been validated on the resource allocation data with promising results.
Vanishing conductivity of quantum solitons in polyacetylene

description: Quantum solitons or polarons are supposed to play a crucial role in the electric conductivity of polyacetylene, in the intermediate doping regime. We present an exact fully quantized calculation of the quantum soliton conductivity in polyacetylene and show that it vanishes exactly. This is obtained by applying a general method of soliton quantization, based on order-disorder duality, to a Z(2)-symmetric complex extension of the TLM dimerization effective field theory. We show that, in this theory, polyacetylene solitons are sine-Gordon solitons in the phase of the complex field.

software reliability

description: Software reliability is estimated using software reliability growth models. In the last few decades, numerous software reliability growth models (SRGMs) have been established. Some models are developed with the consideration of perfect debugging, imperfect debugging, testing coverage, testing effort, and fault reduction factor. Generally, SRGMs are dependent on dataset and thus it is a challenging task to select SRGM appropriately based on the need of software user. As the inappropriate selection of SRGM can lead to inaccurate results and consequently delay in software release. To address this issue, we have combined the two multi-criteria decision-making (MCDM) approaches namely Entropy and Elimination et Choice Translating Reality (ELECTRE) methods. The proposed approach identifies the criterion importance as to select suitable SRGM, comparison of criteria is important. The outcomes are based on the aggregate value of dominant matrix that is being used for SRGMs ranking. The working of proposed Entropy-ELECTRE method is demonstrated on a real time data set on which ten SRGMs are compared against six evaluation criteria. The findings play an important role in determining the SRGM's appropriateness for decision-maker.
The Quasar Outflow Contribution to AGN Feedback: VLT Measurements of SDSS J0318-0600

description: We present high spectral resolution VLT observations of the BAL quasar SDSS J0318-0600. This high quality data set allows us to extract accurate ionic column densities and determine an electron number density of n_e=10^3.3 +/- 0.2 cm^-3 for the main outflow absorption component. The heavily reddened spectrum of SDSS J0318-0600 requires purely silicate dust with a reddening curve characteristic of predominately large grains, from which we estimate the bolometric luminosity. We carry out photoionization modeling to determine the total column density, ionization parameter and distance of the gas and find that the photionization models suggest abundances greater than solar. Due to the uncertainty in the location of the dust extinction, we arrive at two viable distances for the main ouflow component from the central source, 6 and 18 kpc, where we consider the 6 kpc location as somewhat more physically plausable. Assuming the canonical global covering of 20% for the outflow and a distance of 6 kpc, our analysis yields a mass flux of 120 M_sun yr^-1 and a kinetic luminosity that is ~0.1% of the bolometric luminosity of the object. Should the dust be part of the outflow, then these values are ~4x larger. The large mass flux and kinetic luminosity make this outflow a significant contributor to AGN feedback processes.

Reliability Analysis of Periodically Inspected Systems under Imperfect Preventive Maintenance
Creators: name: Agarwal, Shweta
name: S.B. Singh
Publisher: name: Reliability: Theory & Applications
Year: 2021
Subjects: reliability
imperfect preventive maintenance
steady-state availability

description: In this study a periodically inspected system is analyzed which is subject to imperfect maintenance policy. The considered system is inspected and maintained periodically and passes through a fixed number of imperfect repairs before being replaced. The imperfect effect of the preventive maintenance is modelled on the basis of the increasing failure rate of the system. Since the preventive maintenance is imperfect, it brings the considered system to an operating state which lies between two states, namely the “as bad as old state” and “as good as new state”. The distribution of the failure time of the system and that of the repair times are assumed to be arbitrary. The times required for the preventive maintenance of the system and its replacement are further assumed to be negligible. Incorporating the given facts, the reliability of the periodically inspected system is evaluated. Also, various reliability measures like availability, steady-state availability are estimated. An optimal interval of inspection is estimated so that the total cost in minimized. With the help of a case study on Nuclear Power Plant System (NPPS) the derived results are illustrated.

description: We have used the SINFONI integral field spectrograph to map the near-infrared K-band emission lines of molecular and ionised hydrogen in the central regions of two cool core galaxy clusters, Abell 2597 and Sersic 159-03. Gas is detected out to 20 kpc from the nuclei of the brightest cluster galaxies and found to be distributed in clumps and filaments around it. The ionised and molecular gas phases trace each other closely in extent and dynamical state. Both gas phases show signs of interaction with the active nucleus. Within the nuclear regions the kinetic luminosity of this gas is found to be somewhat smaller than the current radio luminosity. Outside the nuclear region the gas has a low velocity dispersion and shows smooth velocity gradients. There is no strong correlation between the intensity of the molecular and ionised gas emission and either the radio or X-ray emission. The molecular gas in Abell 2597 and Sersic 159-03 is well described by a gas in local thermal equilibrium (LTE) with a single excitation temperature T_exc ~ 2300 K. The emission line ratios do not vary strongly as function of position, with the exception of the nuclear regions where the ionised to molecular gas ratio is found decrease. These constant line ratios imply a single source of heating and excitation for both gas phases.

description: A real-life bleaching system is proposed, and its reliability function is estimated using universal generating function technique. The units are connected to each other in series and parallel arrangements. Further, a 2-out-of-4 system is described and taken as an example where out of 4 units, if 2 are working the system will perform its task. Universal Generating Function technique is applied to both the systems and by using Owen’s and Boland method signature, tail signature, Barlow-Proschan Index and expected time of the proposed complex system is calculated.
