In this paper, we bridge work in rock climbing route generation and grading into the computational creativity community. We provide the necessary background to situate that literature and demonstrate the domain's intellectual merit in the computational creativity community. We provide a guiding set of desiderata for future work in this area. We propose an approach to computational route grading. Finally, we identify important gaps in the literature and consider how they may be filled. This paper thus also serves as a pilot study, planting a flag for our ongoing research in this domain.
By a cation substitution strategy, two new hydroxyborates AB11O16(OH)2 (A = K and Cs) were synthesized, and KB11O16(OH)2 exhibits a short DUV cutoff edge (195 nm) and a large birefringence.
Hand and finger movements are a mainstay of piano technique. Automatic Fingering from symbolic music data allows us to simulate finger and hand movements. Previous proposals achieve automatic piano fingering based on knowledge-driven or data-driven techniques. We combine both approaches with deep reinforcement learning techniques to derive piano fingering. Finally, we explore how to incorporate past experience into reinforcement learning-based piano fingering in further work.
In order to increase the electric energy efficiency of production machines, it is necessary to determine the energy demand of the constituent electric loads. Therefore, a new measurement system based on nonintrusive load monitoring is proposed in this paper. It only measures the voltage and current of the aggregate load and then uses automatic disaggregation methods to estimate the energy demand of the constituent loads. In two case studies, the energy demand of most loads could be determined with an accuracy of 85~\% or more in this way.

This study aims to utilize Prussian Blue (PB) to develop a high performance adsorbent for removing radioactive cesium from radioactive accidents. Prussian blue (PB) can adsorb selectively to cesium (Cs), which is high in adsorption efficiency, but has a disadvantage that it is difficult to recover after adsorption, so there is a high concern about secondary environmental pollution. Therefore, this study modified the surface of powder activated carbon (PAC) particles by using covalent organic polymer (COP) for stable immobilization of PB, and developed a PB-impregnated adsorbent (COP-PAC-PB). Synthesis of COP-PAC-PB was performed by sequentially reacting with iron (III) chloride and potassium ferrocyanide solution to synthesize PB in COP pore (In-situ). The maximum adsorption of COP-PAC-PB on cesium was 19 mg / g and the removal efficiency for radioactivity cesium (Cs-137, 60 Bq / kg) was 97.3%. In addition, PB was synthesized by the same method as that of COP-PAC-PB, which is a modification product of the unmodified group (PAC, Ox-PAC), and UV-vis analysis was performed to compare PB desorption characteristics after washing Respectively. In the unmodified group (PAC-PB, Ox-PAC-PB), a large amount of PB was desorbed when washed once to 6 times. In the case of COP-PAC-PB, it was not. As a result, the surface of the PAC particles was effectively modified using COP, and the adsorbent with Prussian blue stably immobilized was developed.
The core of data science is our fundamental understanding about data intelligence processes for transforming data to decisions. One aspect of this understanding is how to analyze the cost-benefit of data intelligence workflows. This work is built on the information-theoretic metric proposed by Chen and Golan for this purpose and several recent studies and applications of the metric. We present a set of extended interpretations of the metric by relating the metric to encryption, compression, model development, perception, cognition, languages, and news media.
A novel approach to integrated ground and air public transport journey planning, operating at continent scale. Flexible date search, prerequisite for long distance trips given their typical low and irregular service frequencies, is core functionality. The algorithm is especially suited for irregular and poorly structured networks. Almost all of the described functionality is implemented in a working prototype. Using ground transport only, the system is on par with Google Transit on random country-wide trips in the US.

We use first-order perturbation theory to provide a local linear relation between the circuit parameters and the poles of an RLC network. The sensitivity matrix, which defines this relationship, is obtained from the systems eigenvectors and the derivative of its eigenvalues. In general, the sensitivity matrix is related to the equilibrium fluctuations of the system. In particular, it may be used as the basis for a statistical model to efficiently predict the sensitivity of the circuit response to small component variations. The method is illustrated with a calculation of conditional probabilities by Monte Carlo Simulation.
Decimal-to-binary conversion is important to modern binary computers. The classical method to solve this problem is based on division operation. In this paper, we investigate a decimal-to-binary conversion method based on addition operation. The method is very easily implemented by software. The cost analysis shows that the latter is more preferable than the classical method. Thus the current Input/Output translation hardware to convert between the internal digit pairs and the external standard BCD codes can be reasonably removed.
Engineering activities involve large groups of people from different domains and disciplines. They often generate important information flows that are difficult to manage. To face these difficulties, a knowledge engineering process is necessary to structure the information and its use. This paper presents a deployment of a knowledge capitalization process based on the enrichment of MOKA methodology to support the integration of Process Planning knowledge in a CAD System. Our goal is to help different actors to work collaboratively by proposing one referential view of the domain, the context and the objectives assuming that it will help them in better decision-making.
Designing of microprocessor based controllers requires specific hardware as well as software programming. Programming depends upon type of the software whether operating software or application software. Programming requires knowledge of system configuration and controller specific programming. Programs are always in digital form so microprocessor can control directly at digital level called Direct Digital Control (DDC).
Spectrum sensing is the challenge for cognitive radio design and implementation, which allows the secondary user to access the primary bands without interference with primary users. Cognitive radios should decide on the best spectrum band to meet the Quality of service requirements over all available spectrum bands. This paper investigates the integrated centralized spectrum sensing techniques in multipath fading environment and the performance was analyzed with energy detection and wavelet based sensing techniques for unknown signal. Keywords: Cognitive Radio, Spectrum Sensing, Signal Detection, Primary User, Secondary User
This note describes a parameter-free implementation of Central Force Optimization for deterministic multidimensional search and optimization. The user supplies only one input: the objective function to be maximized, nothing more. The CFO equations of motion are simplified by assigning specific values to CFO's basic parameters, and this particular algorithmic implementation also includes hardwired internal parameters so that none is user-specified. The algorithm's performance is tested against a widely used suite of twenty three benchmark functions and compared to other state-of-the-art algorithms. CFO performs very well indeed. Includes important update 20 March 2010 addressing the issue of different probes coalescing into one.
This paper presents a semantic wiki prototype application named SHAWN [later WikSAR] that allows structuring concepts within a wiki environment. To entice the use of Semantic Web technologies applications need to offer both high usability and instant gratification. Concept creation is exceptionally easy in SHAWN since metadata as well as plain text is entered within a single edit box on each wiki page in a self-explaining fashion. The entered data is immediately used for rendering sophisticated navigational means on the wiki. By editing simple wiki pages ontologies emerge.
Hierarchical application of Triple-Modular Redundancy (TMR) increases fault tolerance of digital Integrated Circuit (IC). In this paper, a simple probabilistic model was proposed for analysis of fault masking performance of hierarchical TMR networks. Performance improvements obtained by second order TMR network were theoretically compared with first order TMR network.
