description: This paper presents a parametric model approach to address the problem of photovoltaic generation forecasting in a scenario where measurements of meteorological variables, i.e., solar irradiance and temperature, are not available at the plant site. This scenario is relevant to electricity network operation, when a large number of PV plants are deployed in the grid. The proposed method makes use of raw cloud cover data provided by a meteorological service combined with power generation measurements, and is particularly suitable in PV plant integration on a large-scale basis, due to low model complexity and computational efficiency. An extensive validation is performed using both simulated and real data.

description: Anisops (Brooks 1951)
The descriptions of Brooks (1951) are predominantly of the flightless morph (Appendix 2) with 53 of this morph alone, 11 of the flying morph and 16 of both morphs to a greater or lesser degree. In the remainder (16) it is not clear which morph was described or whether a second morph was included in the descriptions.
This revision of the genus Anisops includes 96 species, 30 of which were newly described. The descriptions closely follow the pattern established by Hungerford and document for each species key elements of dimensions, colour, and head to pronotal width. Brooks notes, that as for Notonecta, ‘most of the older descriptions were based on color and it is almost impossible to determine species on this basis’. Brooks instead relies to a large degree on the chaetotaxy of the male front leg.
Brooks often used latinized terms for colour and although some can be readily interpreted as defining each morph others, such as the commonly used colour testaceous, are less definitive. A pale testaceous, fulvous, or stramineous scutellum clearly describes a flightless morph, but rufo-testaceous or merely testaceous are ambiguous. However, any specimen described as having a black, fuscous, or fuliginous scutellum is recognisable as a flight-capable morph. Many descriptions refer also to pale, brown, or dark forms. Brooks certainly recognised that there was some sort of dimorphism or polymorphism in his species, without recognizing that his colour forms were indicative of flight-muscle or wing polymorphism

description: Buenoa (Truxal 1953)
Forty-two species and subspecies are described in Truxal’s (1953) revision (Appendix 3); the flying morph in 11, the flightless morph in 15, and both morphs in 9. Seven descriptions could be of either morph and are not assigned. Ten of the flightless morph species were recorded as having wing polymorphism. From the outset Truxal indicated that he knew a range of forms existed in his species, although the uncommon ones received only scant comment. He was, however, perplexed by the variability in the pigmentation of his specimens and many of his descriptions end with the sentence ‘This species variable in color.’
This is the third of the series of revisions from the University of Kansas. It is an interesting account as it appears that as Truxal became more familiar with the genus during his research the species’ accounts become more detailed and perceptive. For instance, not until number 20 (B. nitida) were pale and dark forms noted and not until number 24 (B. gracilis) was wing polymorphism (brachyptery or macroptery) recorded, as though only at this stage in the revision was it discovered. From number 27 (B. macrotibialis) the numbers of brachypterous and macropterous specimens are recorded in the distribution data. As wing polymorphism is apparently common within this genus, but not always recorded, it is uncertain for most species whether the pale specimens described are wing or flight-muscle morphs. Specimens of each would have rather similar appearance in cursory inspection and the polymorphism would only be defined more precisely if the wings were examined.

description: Enithares (Lansbury 1968)
Appendix 4 shows that of the 47 species from the Oriental Region in Lansbury (1968) account, only the flying morph is described in 6, only the flightless morph in 5, but both morphs in greater or lesser detail in 22. In a further 12 species one of the morphs being described is clearly apparent while the other is in doubt, whereas in two species it is uncertain which morph is described. In E. ciliata and E. lineatipes three colour forms are described, a pale, intermediate, and dark. The dark one is certainly the flying morph and the other two are likely to be pigmented variations of the flightless one.
Lansbury noted in his introduction that, as long known, many species have two colour forms and ‘where fairly large series of specimens have been available for study, i.e., E. woodwardi, every kind of intergrade between the pale and almost melanic form has been found. Therefore, no reliance should be placed on color in naming Enithares.’ His next sentence states that the most dominant colour forms are described, but does not designate which one in the text for each species.

description: The Internet of Things (IoT) interconnects multiple physical devices in large-scale networks. When the 'things' coordinate decisions and act collectively on shared information, feedback is introduced between them. Multiple feedback loops are thus closed over a shared, general-purpose network. Traditional feedback control is unsuitable for design of IoT control because it relies on high-rate periodic communication and is ignorant of the shared network resource. Therefore, recent event-based estimation methods are applied herein for resource-aware IoT control allowing agents to decide online whether communication with other agents is needed, or not. While this can reduce network traffic significantly, a severe limitation of typical event-based approaches is the need for instantaneous triggering decisions that leave no time to reallocate freed resources (e.g., communication slots), which hence remain unused. To address this problem, novel predictive and self triggering protocols are proposed herein. From a unified Bayesian decision framework, two schemes are developed: self triggers that predict, at the current triggering instant, the next one; and predictive triggers that check at every time step, whether communication will be needed at a given prediction horizon. The suitability of these triggers for feedback control is demonstrated in hardware experiments on a cart-pole, and scalability is discussed with a multi-vehicle simulation.

description: In this work, we develop an importance sampling estimator by coupling the reduced-order model and the generative model in a problem setting of uncertainty quantification. The target is to estimate the probability that the quantity of interest (QoI) in a complex system is beyond a given threshold. To avoid the prohibitive cost of sampling a large scale system, the reduced-order model is usually considered for a trade-off between efficiency and accuracy. However, the Monte Carlo estimator given by the reduced-order model is biased due to the error from dimension reduction. To correct the bias, we still need to sample the fine model. An effective technique to reduce the variance reduction is importance sampling, where we employ the generative model to estimate the distribution of the data from the reduced-order model and use it for the change of measure in the importance sampling estimator. To compensate the approximation errors of the reduced-order model, more data that induce a slightly smaller QoI than the threshold need to be included into the training set. Although the amount of these data can be controlled by a posterior error estimate, redundant data, which may outnumber the effective data, will be kept due to the epistemic uncertainty. To deal with this issue, we introduce a weighted empirical distribution to process the data from the reduced-order model. The generative model is then trained by minimizing the cross entropy between it and the weighted empirical distribution. We also introduce a penalty term into the objective function to deal with the overfitting for more robustness. Numerical results are presented to demonstrate the effectiveness of the proposed methodology.

description: We present three methods for distributed memory parallel inverse factorization of block-sparse Hermitian positive definite matrices. The three methods are a recursive variant of the AINV inverse Cholesky algorithm, iterative refinement, and localized inverse factorization, respectively. All three methods are implemented using the Chunks and Tasks programming model, building on the distributed sparse quad-tree matrix representation and parallel matrix-matrix multiplication in the publicly available Chunks and Tasks Matrix Library (CHTML). Although the algorithms are generally applicable, this work was mainly motivated by the need for efficient and scalable inverse factorization of the basis set overlap matrix in large scale electronic structure calculations. We perform various computational tests on overlap matrices for quasi-linear Glutamic Acid-Alanine molecules and three-dimensional water clusters discretized using the standard Gaussian basis set STO-3G with up to more than 10 million basis functions. We show that for such matrices the computational cost increases only linearly with system size for all the three methods. We show both theoretically and in numerical experiments that the methods based on iterative refinement and localized inverse factorization outperform previous parallel implementations in weak scaling tests where the system size is increased in direct proportion to the number of processes. We show also that compared to the method based on pure iterative refinement the localized inverse factorization requires much less communication.

description: Two fundamental approaches to information averaging are based on linear and logarithmic combination, yielding the arithmetic average (AA) and geometric average (GA) of the fusing initials, respectively. In the context of target tracking, the two most common formats of data to be fused are random variables and probability density functions, namely $v$-fusion and $f$-fusion, respectively. In this work, we analyze and compare the second order statistics (including variance and mean square error) of AA and GA in terms of both $v$-fusion and $f$-fusion. The case of weighted Gaussian mixtures representing multitarget densities in the presence of false alarms and misdetection (whose weight sums are not necessarily unit) is also considered, the result of which appears significantly different from that for a single target. In addition to exact derivation, exemplifying analysis and illustrations are provided.

description: This paper deals with the problem of allocating communication resources for Networked Control Systems (NCSs). We consider an NCS consisting of a set of discrete-time LTI plants whose stabilizing feedback loops are closed through a shared communication channel. Due to a limited communication capacity of the channel, not all plants can exchange information with their controllers at any instant of time. We propose a method to find periodic scheduling policies under which global asymptotic stability of each plant in the NCS is preserved. The individual plants are represented as switched systems, and the NCS is expressed as a weighted directed graph. We construct stabilizing scheduling policies by employing cycles on the underlying weighted directed graph of the NCS that satisfy appropriate contractivity conditions. We also discuss algorithmic design of these cycles.

description: Some properties of numerical time integration methods using summation by parts operators and simultaneous approximation terms are studied. These schemes can be interpreted as implicit Runge-Kutta methods with desirable stability properties such as $A$-, $B$-, $L$-, and algebraic stability. Here, insights into the necessity of certain assumptions, relations to known Runge-Kutta methods, and stability properties are provided by new proofs and counterexamples. In particular, it is proved that a) a technical assumption is necessary since it is not fulfilled by every SBP scheme, b) not every Runge-Kutta scheme having the stability properties of SBP schemes is given in this way, c) the classical collocation methods on Radau and Lobatto nodes are SBP schemes, and d) nearly no SBP scheme is strong stability preserving.

description: In order to coordinate multiple different scheduling objectives from the perspectives of economy, environment and users, a practical multi-objective dynamic optimal dispatch model incorporating energy storage and user experience is proposed for isolated microgrids. In this model, besides Microturbine units, energy storage is employed to provide spinning reserve services for microgirds; and furthermore, from the perspective of demand side management, a consumer satisfaction indicator is developed to measure the quality of user experience. A two-step solution methodology incorporating multi-objective optimization (MOO) and decision analysis is put forward to address this model. First, a powerful heuristic optimization algorithm, called the θ-dominance based evolutionary algorithm, is used to find a well-distributed set of Pareto-optimal solutions of the problem. And thereby, the best compromise solutions (BCSs) are identified from the entire solutions with the use of decision analysis by integrating fuzzy C-means clustering and grey relation projection. The simulation results on the modified Oak Ridge National Laboratory Distributed Energy Control and Communication lab microgrid test system demonstrate the effectiveness of the proposed approach.

description: Flow Models based on hyperbolic partial differential equations (conservation laws) are a well-established approach for the material flow simulation. Until now, they have been exclusively used for the simulation of cylindrical cargo. This paper investigates the application of flow models on cubical cargo as a new simulation approach for parcel logistics. Selected flow model parameters are adapted to cover this new situation. The simulation results of this macroscopic model are compared with the microscopic Discrete Element Method (DEM) where the cargo is approximated by superquadrics. An experimental setup especially designed for the validation of the considered flow model for cubical cargo bulk flow is presented. Results of the flow model are analyzed and validated against the results of experiment and DEM for the test setting.

description: We present IS-MPC, an intrinsically stable MPC framework for humanoid gait generation which incorporates an explicit stability constraint in the formulation. The proposed method uses as prediction model a dynamically extended LIP where ZMP velocities are the control inputs, producing in real time a gait (including footsteps with the associated timing) that realizes omnidirectional motion commands coming from an external source. The stability constraint links the future ZMP velocities to the current system state so as to guarantee the essential requirement that the generated CoM trajectory is bounded with respect to the ZMP trajectory. Since the control horizon of the MPC algorithm is finite, only part of the future ZMP velocities are decision variables of the QP problem; the remaining part, called tail, must be either conjectured or anticipated using preview information on the reference motion. Several possible options for the tail are discussed, and each of them is shown to correspond to a specific terminal constraint. A theoretical analysis of the feasibility of the generic MPC iteration is developed and used to obtain sufficient conditions for recursive feasibility. Finally, it is proved that IS-MPC guarantees stability of the CoM/ZMP dynamics if it is recursively feasible. Simulation and experimental results on the NAO and the HRP-4 humanoids are presented to illustrate the performance of the proposed method.

Nine age groups were described for the sample from Caruaru, identified as T. laurentius (Fig 1.A–I). As expected, the wear of occlusal surface of cheekteeth varied considerably during ontogeny. Age 1 shows pre-molar and first molar erupted (Fig 1.A), while the second molar begins to erupt at age 2, but its occlusal surface is completely formed only in age 3 (Figs 1.B and 1.C). These three ages, before the eruption of third molar, are grouped in Juvenile category. The third molar is erupted at age 4 (Fig 1.D) and its occlusal surface is completely formed at age 5 (Fig 1.E). These ages are grouped in Sub-adult category. All specimens have basisphenoid-basiocciptal suture obliterated at age 6, marking the Adult. The first signal of wear appears at age 6 in pre-molar, and at age 7, both flexi of pre-molar and first molar leaves the impression of an enamel island, even as the first flexus of second molar (Fig 1.G). Senile specimens show severe wear of cheek teeth’s occlusal surface. All flexi looks like an enamel island (Fig 1.H) even as the hypoflexi of pre-molar and first molar (Fig. 1.I). Most cranial characters observed and the wear of cheekteeth varied during ontogeny. However, some aspects of the skull did not vary, as the extension of the supra-orbital ridge, which always reaches the suture between frontal and squamosal. The anterior palatal foramens are always anterior to the anterior margin of the pre-molars. The mesopterygoid fossa is "V"-shaped; the interpremaxilar foramen is oval, narrow and short; and the incisive foramen is rounded, and does not show a constriction at the suture between pre-maxila and maxilla (Fig 4.A). The shape of the hamular process of the pterygoid bones is has a pointed shape. (Fig 5.A). Finally, the pre-maxillary portion of the septum of the incisive foramen exceeds half of the length of the foramen (Fig 4.A). The nasal bones reach posterior limit of pre-maxilla only at ages 1 to 3. The ventral crest of the infra-orbital foramen develops through ontogeny. The position of ventral crest at age 1 is after the edge of infra-orbital foramen. However, from sub-adult the ventral crest is anterior to the edge of infra-orbital foramen. The post-orbital process of zygomatic arch can be formed by only squamosal, only jugal or a combination of these two bones. The posterior palatal foramens are located at posterior limit of palate. At age 1, the mesopterigoid fossa reaches posterior margin of first molar and at age 9 it extends up to half of the third molar.

description: We develop a numerical framework to implement the cumulative density function (CDF) method for obtaining the probability distribution of the system state described by a kinematic wave model. The approach relies on Monte Carlo Simulations (MCS) of the fine-grained CDF equation of system state, as derived by the CDF method. This fine-grained CDF equation is solved via the method of characteristics. Each method of characteristics solution is far more computationally efficient than the direct solution of the kinematic wave model, and the MCS estimator of the CDF converges relatively quickly. We verify the accuracy and robustness of our procedure via comparison with direct MCS of a particular kinematic wave system, the Saint-Venant equation.

description: The objective of this paper is to develop an Artificial Neural Network (ANN) model to estimate simultaneously, parameters and state of a brushed DC machine. The proposed ANN estimator is novel in the sense that his estimates simultaneously temperature, speed and rotor resistance based only on the measurement of the voltage and current inputs. Many types of ANN estimators have been designed by a lot of researchers during the last two decades. Each type is designed for a specific application. The thermal behavior of the motor is very slow, which leads to large amounts of data sets. The standard ANN use often Multi-Layer Perceptron (MLP) with Levenberg-Marquardt Backpropagation (LMBP), among the limits of LMBP in the case of large number of data, so the use of MLP based on LMBP is no longer valid in our case. As solution, we propose the use of Cascade-Forward Neural Network (CFNN) based Bayesian Regulation backpropagation (BRBP). To test our estimator robustness a random white-Gaussian noise has been added to the sets. The proposed estimator is in our viewpoint accurate and robust.

description: In this work, we present scalable balancing domain decomposition by constraints methods for linear systems arising from arbitrary order edge finite element discretizations of multi-material and heterogeneous 3D problems. In order to enforce the continuity across subdomains of the method, we use a partition of the interface objects (edges and faces) into sub-objects determined by the variation of the physical coefficients of the problem. For multi-material problems, a constant coefficient condition is enough to define this sub-partition of the objects. For arbitrarily heterogeneous problems, a relaxed version of the method is defined, where we only require that the maximal contrast of the physical coefficient in each object is smaller than a predefined threshold. Besides, the addition of perturbation terms to the preconditioner is empirically shown to be effective in order to deal with the case where the two coefficients of the model problem jump simultaneously across the interface. The new method, in contrast to existing approaches for problems in curl-conforming spaces does not require spectral information whilst providing robustness with regard to coefficient jumps and heterogeneous materials. A detailed set of numerical experiments, which includes the application of the preconditioner to 3D realistic cases, shows excellent weak scalability properties of the implementation of the proposed algorithms.

description: Feedback delay networks (FDNs) belong to a general class of recursive filters which are widely used in sound synthesis and physical modeling applications. We present a numerical technique to compute the modal decomposition of the FDN transfer function. The proposed pole finding algorithm is based on the Ehrlich-Aberth iteration for matrix polynomials and has improved computational performance of up to three orders of magnitude compared to a scalar polynomial root finder. We demonstrate how explicit knowledge of the FDN's modal behavior facilitates analysis and improvements for artificial reverberation. The statistical distribution of mode frequency and residue magnitudes demonstrate that relatively few modes contribute a large portion of impulse response energy.

description: Enterprise resource planning (ERP) is an integrated system that helps companies in managing their resources. There are two types of ERP systems, the traditional ERP systems, and the cloud ERP systems. Cloud ERP systems were introduced after the development of cloud computing technology. This research aims to identify the factors that affect the adoption of cloud ERP in Egyptian companies. Moreover, the aim of our study is to provide guidance to Egyptian companies in the cloud ERP adoption decision and to participate in increasing the number of the cloud ERP studies that are conducted in the Middle East and in developing countries. There are many factors influencing the adoption of cloud ERP in Egyptian organizations which are discussed and explained in the research. Those factors are examined through combining the Diffusion of Innovation theory (DOI) and technology-organization environment framework (TOE). Data were collected through a survey that was developed using constructs from the existing studies of cloud computing and cloud ERP technologies and was then modified to fit our research. The analysis of the data was based on Structural Equation Modeling (SEM) using Smart PLS software that was used for the empirical analysis of the research model.

description: In order to improve the classification accuracy of transient stability assessment of power systems, a novel method based on local learning machine and an improved bacterial colony chemotaxis (BCC) algorithm is proposed, where local learning machine(LLM) is used to build a TSA model. Considering the possible real-time information provided by PMU, a group of system-level classification features extracted from the power system operation parameters are employed as inputs, and the stability result is used as output of the LLM model. The relation ship between input and output is trained and the ideal model is obtained by applying the improved BCC combined with chaotic search strategy to determine the optimal parameters of LLM automatically. The effectiveness of the proposed method is shown by the simulation results on the New England 10-unit-39-bus power system.

description: The Internet of Things (IoT) relies on networks of physical objects equipped with sensors and actuators to collect and share data for analysis and decision-making. Wireless sensor networks are fundamental to IoT infrastructure. Binary Sensor Networks, which use simple and cost-effective devices with limited processing capabilities, are increasingly prevalent in IoT applications. They offer advantages over traditional wireless sensor networks by reducing reliance on noisy Received Signal Strength values influenced by environmental factors. Many sophisticated sensors can also function as binary-detection devices by producing binary reports based on predefined thresholds. This binary information is used to determine the presence or absence of a device within a specified area, impacting network coverage, deployment, and accuracy in localization and tracking. This research addresses various problems using binary information, with a focus on IoT applications. It explores the potential of Binary Sensor Networks to improve the efficiency and reliability of IoT systems, especially in situations where complex sensors are not required. The study investigates methods for optimizing coverage, deployment, and positioning accuracy by leveraging binary data, which has practical implications for a wide range of IoT scenarios.

description: This paper proposes a data-driven approach, by means of an Artificial Neural Network (ANN), to value financial options and to calculate implied volatilities with the aim of accelerating the corresponding numerical methods. With ANNs being universal function approximators, this method trains an optimized ANN on a data set generated by a sophisticated financial model, and runs the trained ANN as an agent of the original solver in a fast and efficient way. We test this approach on three different types of solvers, including the analytic solution for the Black-Scholes equation, the COS method for the Heston stochastic volatility model and Brent's iterative root-finding method for the calculation of implied volatilities. The numerical results show that the ANN solver can reduce the computing time significantly.
