An innovative approach to identifying knowledge management problems

The promised benefits from implementing knowledge management (KM) attract an increasing number of organizations. However, many organizations, face several difficulties when designing a KM system or implementing its initiatives. These difficulties, along with some unsuccessful KM initiatives worry many organizations interested in the concept. This paper investigates the reasons for these difficulties and discusses the issues that need to be addressed to develop robust KM systems. It then introduces a systematic approach for addressing these issues at the early stages of designing a KM system. This approach was developed within the cross‐sectoral learning in the virtual enterprise (CLEVER) project and supports the definition of KM problems within a business context. The approach has been encapsulated into a prototype software system to make it easier to use. The paper describes in detail the operational level of the prototype. It also discusses the potential of the developed prototype, and concludes that it represents an innovative tool for improved KM.
Determination of Catechin Content in Gambir Powder from Dried Gambir Leaves Quickly using FT NIR PLS Model

Conventional production process of gambir often produces gambir with low content of catechin. Engineering of production processes of gambir leaves to produce gambir powder has been developed by previous researchers. The objective of this study was to develop a calibration model to predict the content of catechin in gambir powder from dried gambir leaves quickly using FT-NIR PLS model. Reflectance spectra of gambir powder from dried gambir leaves obtained at a wavelength of 1000 to 2500 nm. Spectra pre-processing treatment method used was a combination between normalization between 0 and 1 (n01) method and first derivative Savitzky-Golay 9 points (dg1). The result showed that correlation coefficient and standard error of prediction (SEP) were 0.99 and 2.10 % respectively, obtained when used 6 factors of partial least square (PLS). Calibration model developed has shown higher accuracy and precision to predict catechin content of gambir powder from dried gambir leaves.
Development and testing of a non-energy-absorbing anchorage system for roadside poles

Abstract Current anchorage systems for poles, lighting columns, etc., have an inherent strength that causes serious injuries, and even death, in cases of vehicle impact. This article explores the deficiency of traditional anchorage systems and explains the development of a new anchorage system over the different phases, such as design conditions, FEM analysis, dynamic testing and actual crash tests. The behaviour of the traditional and new anchorage systems are compared, including the use of a data acquisition system and a high-speed camera. The aim of this study was to develop a new non-energy-absorbing anchorage system, adaptable to lighting poles, signposts, etc., and to evaluate the decrease in primary injuries with the employment of this system.
“Don't think, just shoot” – The paradox of shooting three-point shots in basketball

ABSTRACT A two-phase study was conducted on shooting three-point shots in basketball in pressure/no-pressure game situations. In Phase 1 – a subjective approach, our aim was to discover what the players and coaches thought about shooting beyond the three-point arc when the shooters were performing under defensive pressure or when they were free of such pressure. In Phase 2 – an analysis of shooting success, we examined the actual success (i.e., percentage of successful shots) of shooting three-point shots under these two situations. In Phase 1, 97 Division 1 male basketball players and 12 elite coaches were asked how they perceived shooting three-point shots in various game situations. In Phase 2, the success of 382 three-point shots taken in actual Division 1 games was analyzed. The shots were classified by four expert coaches into two categories – shots taken in free-of-defense and shots taken in under-pressure game situations. The success of the two classified shots was analyzed under 10 conditions. Expected results were found in Phase 1 – both players and coaches believed that the success of three-point shots is higher when the shots are taken when the shooter is free of defense. In Phase 2, a surprising finding was revealed: shooting success was higher when the players shot under defensive pressure. We discuss the data in line with Kahneman’s (2011), Thinking, fast and slow, model, and propose a number of practical implications for coaches who are preparing their three-point shooters to deal with real game situations.
Real-time dispatching of rubber tired gantry cranes in container terminals

Abstract : Within the past 50 years containerization and globalization have driven a change from small container terminals to large container terminals that need efficient logistic models to keep up with the significant growth in container traffic. Efficiently managing of rubber tired gantry cranes and planning container placement within the terminal are two ways to increase the overall efficiency of a terminal. In this thesis, we combine these strategies in a real-time dispatching tool using an approximate dynamic programming heuristic. The heuristic re-optimizes at the rate the quay crane handles containers, incorporating endogenous and exogenous information in each solution. We formulated and solved an Integer Linear Program (ILP) to estimate the heuristic's solution quality. The heuristic finds solutions within seconds and the absolute gap between the heuristic solution and the ILP solutions remained essentially constant as the size of the problem increased.
Audibility of all-pass components in binaural synthesis

Transfer functions can generally be decomposed into a minimum phase component, an allpass component and a pure delay. Earlier investigations have shown that head related transfer functions and headphone transfer functions have all-pass components, but if these do not have an audible impact on the sound it might be beneficial to implement binaural synthesis without them. A subjective experiment is described in which listeners are presented with signals that differ only in terms of a second order all-pass section. The results of the experiment are threshold curves dependent on the centre frequency and Q-factor of the all-pass section. some circumstances. Six thresholds were determined by means of a psycho-acoustical listening experiment involving eight subjects wearing headphones. A threshold for high Q-factors was determined for diotic and dichotic presentation above which the audibility of the all-pass section will increase with its Q-factor. This threshold for a causal all-pass section is slightly higher than for its non-causal counterpart indicating that a non-causal all-pass section becomes audible at lower Q-factors. Whether the all-pass was applied diotically or dichotically does not influence the results markedly. On the other hand for low Q-factors thresholds were determined for dichotic presentation where the causality of tile impulse response showed little influence.
A New Approach To Broad-band Matching for P-i-n Photodiodes

Microwave transmission-line theory has been applied to calculate p-i-n photodiode systems in which the carrier transit time, the geometric configuration, and the transmission-line characteristics were considered. The thickness of the intrinsic layer has been optimized to obtain a wide 3-dB bandwidth and a maximum gain-bandwidth product. A simulated result of 40-GHz bandwidth has been obtained for a device with a 20 x 20 mum2 p-i-n area. (C) 1995 John Wiley & Sons, Inc.
An interpretable outcome prediction model based on electronic health records and hierarchical attention

Outcome prediction aims to predict the future health condition of patients from Electronic Health Record (EHR) data. Because of the sequential characteristic of EHR data, recurrent neural network (RNN)‐based outcome prediction methods have achieved state‐of‐the‐art results. However, the major drawback of RNN‐based outcome prediction methods is lack of interpretability, which would lead to trust issues. Aiming at this problem, this paper proposes interpretable outcome prediction model with hierarchical attention (IoHAN), an interpretable outcome prediction model by leveraging attention mechanism. The main novelty of IoHAN is that it can pinpoint the fine‐grained influence on the final prediction result of each medical component by decomposing the attention weights hierarchically into hospital visits, medical variables, and interactions between medical variables. We evaluated IoHAN on MIMIC‐III, a large real‐world EHR data set. The experiment results demonstrate that IoHAN can achieve higher prediction accuracy than state‐of‐the‐art outcome prediction models. In addition, the hierarchical decomposed attention weights can interpret the prediction results in a more natural and understandable way.
Base Pressure Measurements under a Scale Model Stockpile

ABSTRACT The ability of a granular bulk material to transmit internal shear stress is a fundamental property that is often overlooked or underestimated, yet it is this ability that allows many observed physical phenomena to occur. One such area that continues to be a focus for numerical, theoreticals and experimental researchers is the pressure that a stockpile of granular material places on the supporting surface. While appearing to be a simple problem, the ability of granular materials to transmit shear stress makes this an extremely complex problem. This article presents high-quality data collected under a 2 m high stockpile and full details of the experimental facilities used in the collection of the data. The work presented is of significant value, having a much greater scale than previous studies (Jotaki & Moriyama, 1979; Lee & Herington, 1971; Smid & Novosad, 1981), and the deliberate inclusion of a central reclaim channel offers insight into stress changes during gravity reclaim and refilling. The results of this work have shown that the so-called ‘M’ pressure does exist under larger stockpiles both with and without reclaim hoppers; of more significance is the reemergence of the M pressure upon refilling of an emptied stockpile. This clearly illustrates that the M pressure is a robust and natural pressure distribution for a conical stockpile.

The text has a modular structure, which not only organizes the presentation, but also provides a format that allows instructors flexibility and preference in designing material for the course. The presentation does not compromise economic theoretical concepts, but it does complement economic theory with timely, real-world applications. This text is intended to give undergraduate and MBA students a clear perspective of the relationship between market activity and the environment. The text integrates the business perspective in the development of environmental decision-making - a vantage point often overlooked in more conventional treatments. The general approach uses economic analytical tools such as market models, benefit-cost analysis, and risk analysis to assess environmental problems and to evaluate policy solutions.
Building Pathways: apprenticeships as a route to higher education

Purpose – This paper aims to present apprentices’ perceptions of their opportunities for progressing to higher education. Data gained through semi‐structured interviews with apprentices is placed in the context of the current policy agenda to widen participation in higher education and to increase the skills levels of those in employment. These policies are paramount for apprentices, many of whom fit both of these criteria. The research reported in this paper aims to answer the question “Do apprentices perceive there to be barriers in progressing to higher education? ”Design/methodology/approach – In total 44 interviews were conducted with apprentices during college placements and further interviews were conducted with apprentices who had progressed to higher education courses (HNC and HND) at the same colleges.Findings – The findings show that employer support, time, finance and apprentices’ perceptions of their own ability are the key factors that determine whether apprentices will progress to higher‐lev.
Potential Use of Native Yeasts to Produce Bioethanol and Other Byproducts from Black Sugarcane, an Alternative to Increment the Subsistence Farming in Northern Ecuador

The high consumption of energy, mainly in the automotive sector, is supplied by fossil fuels, which, when combusted, generate polluting gases leading to the great problem of climate change. This has led society to seek alternatives. Bioethanol is a biofuel that can be obtained from the fermentation of different raw materials rich in sucrose such as sugarcane, which can be mixed with gasoline and used to reduce polluting emissions. The following investigation focused on studying the efficiency of three selected native yeasts in the fermentation of black sugarcane POJ 27-14 variety juice to produce bioethanol and other byproducts of biotechnological interest. A comparison between the size of the inoculum of three selected native yeasts (Lev6, Lev9, and Lev30) and two reference commercial controls in the fermentation process was performed. The phylogenetic classification was carried out based on the analysis of the internal transcribed spacer 1 sequence, 5.8S ribosomal RNA, and internal transcribed spacer 2. Lev6 and Lev30 were classified as Saccharomyces cerevisiae, while Lev9 was Candida intermedia, with 99% nucleotide sequence identity. The results showed that the optimal growth temperature was 30 °C with constant agitation (200 rpm) for biomass production. The Lev30 strain presented the highest yield in the production of biomass from sugarcane juice fermentation, while the Lev6 strain presented the highest yield in ethanol production. Additionally, among native yeasts, Lev6 registered the highest ethanol concentration (Q) and volumetric productivity (Qp) values of 0.61 (g/L/h) and 43.92 g/L, respectively, which were comparable with the control yeasts. The gas chromatography coupled to mass spectrometry (GC-MS) indicated the presence of ethanol in all samples (98% to 99% relative percentages) along with some therapeutic substances such as (2-aziridinylethyl) amine and tetraacetyl-d-xylonic nitrile with greater efficiency than commercial controls from the alcoholic fermentation of black sugarcane juice.
Fungus (Alternaria sp.) Mediated Silver Nanoparticles Synthesis, Characterization and Application as Phyto-Pathogens Growth Inhibitor

Background: Biogenic nanoparticles have proved to be effective biocontrol agents for certain plant diseases. It possesses the potential for extensive use for sustainable agriculture. Many attempts have been made to synthesize nano-based antifungal compounds for the management of soil borne pathogenic fungi for crops.Results: In our work, silver nanoparticles (AgNPs) was constructed with phytopathogenic fungi (Alternaria sp.) which was isolated from banana cultivated soil. Alternaria sp. was able to grow rapidly and produce highly bioactive compounds as safe antifungal agent against plant pathogenic fungi (Fusarium spp. and Alternaria sp.). The size of synthesized silver nanoparticles ranged between 5-10 nm. Analytic tools, such as UV-visible spectroscopy, Fourier transformed infra-red (FTIR) spectroscopy, scanning transmission electron microscopy (STEM), EDS and elemental mapping were used to visualize the formation of AgNPs.

Characterizing Wireless and Powerline Communication Channels with Applications to Smart Grid Networks

Smart grid aims at improving the efficiency, reliability, security, and quality of service (QoS) of the current electricity grid by exploiting the advances in communication and information technology. In parallel to size of the electricity grid, smart grid communication infrastructure should cover a very large geographical area that may extend from remote generation sites to densely populated residential regions and inside buildings, homes, and electricity-power-system environments. In such an extensive communication network, different communication technologies operating on different communication medium are likely to coexist. Among the communication technologies available, wireless and power line communication (PLC) based solutions are comparatively attractive especially considering cost of the initial investment required for the realization of a communication network with such an immense size. In this dissertation, a detailed investigation of wireless and PLC channel characteristics of the smart grid networks is presented. Among the topics discussed are the time variation characteristics of wireless channels, root-mean-squared (RMS) delay spread and path amplitude statistics of PLC channels, and the impact of impulsive noise on orthogonal frequency division multiplexing (OFDM) systems.
Decortication of tropical oilseeds and edible nuts (NRI Bulletin No. 42)

This publication describes NRI experience in the recovery of seven different 'seed kernels' of tropical origin: balanites nuts, cashew nuts, coconuts, cottonseeds, groundnuts, macadamia nuts and sunflower seeds. lt includes the decortication and related operations for specific nuts and oilseeds for human food, as well as the by-products which may have other uses. The structure of the seeds and their implication for decortication are discussed and general descriptions of the typical decortication techniques are included. The effect of crop and processing variables on the efficiency of the operation and the recovery of products is also covered. This publication does not cover decortication processes that are applied to husk, bark or fibre crops resulting in some form of fibre product (e.g. sisal and hemp) without any direct connection to the seeds of a plant.
Towards a comprehensive approach to zero-emissions housing

There are a growing number of examples of housing developments around the world that claim to be zero energy or zero emissions. Some of these clearly indicate that this only refers to the ability to minimize energy requirements for heating and cooling. However, others simply fail to recognize the energy and emissions needed to produce the materials and other components required for housing construction and ongoing maintenance and repair. For a house to be considered as truly net zero emissions, all of the emissions occurring across every stage of its life must be offset. This study calculates the life cycle emissions associated with a new house located in Melbourne, Australia. Based on the findings, an estimate is made of the capacity of a solar photovoltaic (PV) system needed to offset these emissions over the life of the house including the emissions associated with the manufacture and maintenance of the PV system itself. It was found that a 14.9kW system would be needed. The findings from this article provide a great deal of insight into the life cycle global-warming impacts associated with housing and the capacity for these to be offset by on-site solar energy production.
Effect of primary network on performance of spectrum sharing AF relaying

Most of the research in spectrum sharing has neglected the effect of interference from primary users. In this reported work, the performance of spectrum sharing amplify-and-forward relay networks under interference-limited environment, where the interference induced by the transmission of primary networks is taken into account, is investigated. In particular, a closed-form expression tight lower bound of outage probability is derived. To reveal additional insights into the effect of primary networks on the diversity and array gains, an asymptotic expression is also obtained.
Design of a carbon fiber suspension system for FSAE applications

Reducing weight while maintaining structural integrity is one of the key challenges Formula SAE teams face as they try and design the suspension of the formula car. The purpose of this paper is to present experimental data on designing and optimizing a carbon fiber suspension system for formula cars. The reason carbon fiber suspensions are favored over the current steel suspensions is because of they can reduce the weight of the suspension by 50%. Pull tests on an Instron machine were performed on over 15 specimens composed of a carbon fiber tube with an aluminum insert bonded to each end. Loctite E‐120HP epoxy was used and the surface preparation, bond gap, and bond length were varied to find the optimal bond strength. An average bond strength of 2,382.6 pounds per square inch was determined for specimens with surface preparation. Furthermore a bond gap of 0.0065 to 0.008 inches was found to give the strongest bond.
Indoor Air Quality in Healthcare and Care Facilities: Chemical Pollutants and Microbiological Contaminants

The indoor air quality of healthcare and care facilities is poorly studied. The aim of this study was to qualitatively and quantitatively describe the chemical pollution and the microbiological contaminations of the indoor environment of these facilities. Methods: A wide range of chemical compounds (39 volatile and 13 semi-volatile organic compounds, carbon dioxide, fine particulate matter) and microorganisms (fungi and bacteria) were studied. Sampling campaigns were conducted in two French cities in summer 2018 and winter 2019 in six private healthcare facilities (general practitioner’s offices, dental offices, pharmacies) and four care facilities (nursing homes). Results: The highest median concentrations of chemical compounds (μg/m3) were measured for alcohols (ethanol: 378.9 and isopropanol: 23.6), ketones (acetone: 18.8), aldehydes (formaldehyde: 11.4 and acetaldehyde: 6.5) and terpenes (limonene: 4.3). The median concentration of PM2.5 was 9.0 µg/m3. The main bacteria of these indoor environments were Staphylococcus, Micrococcus and Bacillus genera, with median bacterial concentrations in the indoor air of 14 cfu/m3. The two major fungal genera were Cladosporium and Penicillium, with median fungal concentrations of 7 cfu/m3. Conclusions: Indoor air in healthcare and care facilities contains a complex mixture of many pollutants found in higher concentrations compared to the indoor air in French hospitals in a previous study.
