ASSESSING A KNOWLEDGE MANAGEMENT (KM) PROJECT SELECTION FRAMEWORK

Knowledge management (KM) is becoming recognized as a valuable tool for establishing and maintaining competitive advantage. Decision superiority, the ultimate goal of KM, is only possible through the effective and efficient use of knowledge. But, to effectively and efficiently create and use KM, it is important to carefully select KM projects. This research assesses the usefulness of a KM project selection framework that was developed by U.S. Air Force Captain William Bower (2001) and refined by 1st Lt Jeffrey Phillips (2003) referred to here as the BowerPhillips decision framework. To assess the usability of the framework, a case study was undertaken at an Air Force organization to identify and address potential knowledge management opportunities. The framework was found to be useful in identifying possible KM projects.
Adaptive Spectrum Management of Cognitive Radio in Intelligent Transportation System

With the rapid development of urban rail transit, the demand of the public in rail transportationto take real-time, reliable and efficient wireless access services, has become the focus of mobilebroadband communications. Wireless cognitive radio (CR) over urban rail transit is a newly emergingparadigm that attempts to opportunistically transmit in licensed frequencies, without affecting the preassignedusers of these bands. To enable this functionality, such a radio must predict its operationalparameters, such as transmit power and spectrum. These tasks, collectively called spectrum management,is difficult to achieve in a dynamic distributed environment, in which CR users may only takelocal decisions, and react to the environmental changes. In this paper, we propose a reinforcementlearning based approach for spectrum management. Our approach uses value functions to evaluate thedesirability of choosing different transmission parameters, and enables efficient assignment of spectrumsand transmit powers by maximizing long-term reward. We then investigate various real-worldscenarios, and compare the communication performance using different sets of learning parameters.The results proves our reinforcement learning based spectrum management can significantly reduceinterference to licensed users, while maintaining a high probability of successful transmissions in acognitive radio ad hoc network.
Bioerosion and palaeoecological association of osteophagous insects in the Maastrichtian dinosaur
 Arenysaurus ardevoli

Bioerosions produced by the osteophagous diet of animals that fed on dinosaur bones are very scarce in the European fossil record. Herein we present bioerosion on hadrosaurid remains from the Maastrichtian Tremp Formation of the Pyrenean Basin, which is only the second such case recorded from the Iberian‐Occitan Plate besides a sauropod from the Jurassic‐Cretaceous of Valencia. The hadrosaurid fossil record is particularly rich in the Blasi sites of the Tremp Formation located in the municipality of Arén (Huesca, Spain). In this article, bones referred to the hadrosaurid Arenysaurus ardevoli from the Blasi‐3 site are analysed to shed light on the palaeoenvironment and on the presence of a palaeoecological interaction between the hadrosaurid carcase and osteophagous tracemakers. Bioerosions recorded on the bones comprise tunnels, roundish holes, and straight notches, similar to the traces attributed to necrophagous insects (cf. Cuniculichnus seilacheri). Here, we record the first instance of the activity of these animals on dinosaur bones in the Upper Cretaceous of the Ibero‐Occitan Plate. The results presented lead us to infer that the Arenysaurus bones were possibly transported by a storm or similar event to the Blasi‐3 site, where they were exposed to post‐mortem biotic interactions (eaten and partially decomposed by dermestid beetles) for a prolonged time period before they were completely buried. □ dermestid, hadrosaurid, Ibero‐Occitan Plate, necrophagous, taphonomy.
PLYOMETRIC WEIGHT TRAINING CAN INCREASE HIP AND ANKLE JOINT STRENTH SIGNIFICANTLY

The purposes of this study were to (1) investigate the changes in muscle strength and power at each joint of lower extremity, kinetics and stiffness of hip, knee, and ankle joints during counter-movement jump with different weights before and after plyometric weight training (PWT); (2) compare each of the joint contributions during plyometric exercises with different weights. Sixteen basketball players were asked to perform the PWT, i.e. 3 groups continued CMJ with the weight of 30% 1RM for 8-weeks with incremental-loads. Before and after the 8-week training program, kinematics and kinetics of the lower-limb were collected during CMJ performance. Joint moment, joint power, joint stiffness, and joint contirbution were then determined. The results indicated that an 8-week plyometric weight training program could significantly increase jump height, peak GRFv, and power output. The results also revealed that muscle strength and power of hip were dominantly developed during PWT and the enhanced kinetics (moment and stiffness) of hip turned out to be a major factor responsible for the improved jump performance.
Gate Driver Circuit of Power Electronic Switches with Reduced Number of Isolated DC/DC Converter for a Switched Reluctance Motor

This paper presents a gate driver circuit for the switching devices used in the asymmetrical converter for a switched reluctance machine with reduced number of isolated dc/dc converters. Isolation required in the gate driver circuit of switching devices is indispensable. For the purpose of isolation different arrangements may be used such as pulse transformers. The dc/dc converter for isolation and powering the gate drive circuits is suitable, cheaper in cost and simple to implement. It is also significant that required number of isolation converters is much less than the switches used in converter. In addition, a simple logic circuit has been presented for producing the gate signals at correct phase sequence which is compared with the gated signals directly obtained from the encoder of an existing machine.
Work Design in the Contemporary Era

Work design refers to the roles, responsibilities, and work tasks that comprise an individual’s job and how they are structured and organized. Good work design is created by jobs high in characteristics such as autonomy, social support, and feedback, and moderate in job demands such as workload, role ambiguity, and role conflict. Established research shows good work design is associated with work outcomes such as job satisfaction, organizational commitment, work safety, and job performance. Poor work design is characterized by roles that are low in job resources and/or overly high in job demands, and has been linked to poor health and well-being, absenteeism, and poor performance. Work design in the 20th century was characterized by traditional theories focusing on work motivation, well-being, and performance. Motivational and stress theories of work design were later integrated, and work characteristics were expanded to include a whole variety of task, knowledge, social, and work-context characteristics as well as demands, better reflecting contemporary jobs. In the early 21st century, relational theories flourished, focusing on the social and prosocial aspects of work. The role of work design on learning and cognition was also recognized, with benefits for creativity and performance. Work design is affected by many factors, including individual traits, organizational factors, national factors, and global factors. Managers may impact employees’ work design “top-down” by changing policies and procedures, while individuals may change their own work design “bottom-up” through “job crafting. ” In the contemporary era, technology and societal factors play an important role in how work is changing. Information and communication technology has enabled remote working and collaboration across time and space, with positive implications for efficiency and flexibility, but potentially also increasing close monitoring and isolation. Automation has led to daily interaction with technologies like robots, algorithms, and artificial intelligence, which can influence autonomy, job complexity, social interaction, and job demands in different ways, ultimately impacting how motivating jobs are. Given the rapidly changing nature of work, it is critical that managers and organizations adopt a human-centered approach to designing work, with managers sensitive to the positive and negative implications of contemporary work on employees’ work design, well-being, and performance. Further research is needed to understand the multitude of multilevel factors influencing work design, how work can be redesigned to optimize technology and worker motivation, and the shorter- and longer-term processes linking work design to under-researched outcomes like identity, cognition, and learning. Overall, the aim is to create high-quality contemporary work in which all individuals can thrive.
Some constructions of Gabor K-frames

unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Abstract. It is known that a necessary condition for Gabor systems {EmbTnag}m,n∈Z to yield a frame is that ab6 1 (where a,b are the lattice parameters). In this paper we will characterize and construct Gabor (Weyl-Heisenberg) Kframes when ab > 1, and windows are in the Weiner algebra. We will show that an oversampling {Em q Tn a p g}m,n∈Z of a K-frame {EmbTnag}m,n∈Z is also a K-frame. Moreover, we will give a concrete example, in the case when g = χ[0,1), a = 2, b = 1, and we will derive some results.
Monopile as Part of Aeroelastic Wind Turbine Simulation Code

The influence on wind turbine design loads of variations in stiffness and damping of a monopile foundation with soil interaction is demonstrated through a case study, which takes non-linearities into account. The study illustrates the importance of a detailed foundation model, and demonstrates the framework, which is an important part of a successful optimization of wind turbines. In particular for offshore wind turbines at deep water sites the optimization and a thorough modelling of the foundation become increasingly important due to the increasing relative cost of the foundation. The main design requirements are – apart from requirements to strength of the foundation itself – related to the limitation of maximum deflection at the tower base and to the stiffness, which influences the vibration modes of the complete structure and particularly the frequencies of the fundamental, transversal tower modes. In order to limit dynamic amplification of the rotor loads, which contain components that are multiples of the rotor rotational frequency, there must be a safe separation of structural and excitation frequencies. The loads are calculated by use of a fully non-linear aeroelastic wind turbine simulation code, BHawC, which operates in the time domain. The code is developed at Siemens Wind Power during the recent four years. The model discretization is based on finite elements, and the monopile is composed of a series of beam elements. The interaction with the soil is modelled by distributed, non-linear springs and dampers. The external loads include aerodynamic loads and wave loads. The case study is kept within realistic limits by using an existing 2.3 MW wind turbine with a monopile foundation at the Samso offshore site as the base design.

Design of a Helmholtz coil for low frequency magnetic field susceptibility testing

This paper describes the design of a Helmholtz coil that is a candidate test apparatus for low frequency magnetic field susceptibility testing on military equipment and subsystems. Use of this coil would reduce electromagnetic compatibility (EMC) qualification test time, and subject the equipment under test (EUT) to a relatively uniform field which is representative of the actual electromagnetic environment on some naval platforms. Specifically, this paper presents practical analytical expressions that may be used to design a Helmholtz coil for this unique application. Experimental test results for a three foot diameter coil are presented, including: maximum magnetic flux density vs. frequency, impedance vs. frequency, resonant frequency behavior and the effect of coil separation distances greater than one radius.

A Multiobjective Iterated Greedy Algorithm for Truck Scheduling in Cross-Dock Problems

The cross-docking system is a new distribution strategy which can reduce inventories, lead times, and improve responding time to customers. This paper considers biobjective problem of truck scheduling in cross-docking systems with temporary storage. The objectives are minimizing both makespan and total tardiness. For this problem, it proposes a multiobjective iterated greedy algorithm employing advance features such as modified crowding selection, restart phase, and local search. To evaluate the proposed algorithm for performance, it is compared with two available algorithms, subpopulation particle swarm optimization-II and strength Pareto evolutionary algorithm-II. The comparison shows that the proposed multiobjective iterated greedy algorithm shows high performance and outperforms the other two algorithms.
Physical Parameter Variation Analysis on the Performance Characteristics of Nano DG-MOSFETs

DG-MOSFETs are the most widely explored device architectures for na-no-scale CMOS circuit design in sub-50 nm due to the improved subthreshold slope and the reduced leakage power compared to bulk MOSFETs. In thin-film (t si < 10 nm) DG-MOS structures, charge carriers are affected by t si induced quantum confinement along with the confinement caused by a very high electric field at the interface. Therefore, quantum confinement effects on the device characteristics are also quite important and it needs to be incorporated along with short channel effects for nano-scale circuit design. In this paper, we analyzed a DG-MOSFET structure at the 20 nm technology node incorporating quantum confinement effects and various short channel effects. The effect of physical parameter variations on performance characteristics of the device such as threshold voltage, subthreshold slope, I ON - I OFF ratio, DIBL, etc. has been investigated and plotted through extensive TCAD simulations. The physical parameters considered in this paper are operating temperature (T op ), channel doping concentration (N c ), gate oxide thickness (t ox ) and Silicon film thickness (t si ). It was observed that quantum confinement of charge carriers significantly affected the performance characteristics (mostly the subthreshold characteristics) of the device and therefore, it cannot be ignored in the subthreshold region-based circuit design like in many previous research works. The ATLAS TM device simulator has been used in this paper to perform simulation and parameter extraction. The TCAD analysis presented in the manuscript can be incorporated for device modeling and device matching. It can be used to illustrate exact device behavior and for proper device control.
Jitter testing technique and results at VC-4 desynchronizer output of SDH equipment

Many parameters have to be taken into account when testing an SDH (Synchronous Digital Hierarchy) apparatus. Specifications relative to jitter and wander generation, at the output of desynchronizer systems, represents one of the hottest topics in characterising SDH equipment. Among the many factors involved, pointer justifications, due to phase variations between the clock of the received timing signal and the internal clock of SDH equipment, play indeed a primary role in phase noise accumulation. This paper deals with the effects of AU pointer justifications, combined with the asynchronous mapping of plesiochronous tributaries in VC-4, in the phase rebuilding process of the demapped tributaries. Moreover, a detailed description of the testing technique is provided. Two different kinds of test have been designed for measuring and analysing phase transients from O Hz on, namely dynamic jitter measurement configuration and static jitter measurement configuration. Some results, obtained by applying this technique on different suppliers piece of equipment, are presented and their relative impact on normative is highlighted. <<ETX>>
Experimental evaluation of a rotor flux oriented control algorithm for brushless doubly-fed machines

The brushless doubly-fed machine (BDFM) has shown potential for adjustable speed drive applications. Although the BDFM is readily applicable for industrial drives requiring only slow speed response, control methods for higher performance operation need to be explored. With the help of a suitable synchronous reference frame dq model, this paper defines a BDFM synchronous angle and employs an electric torque estimator to establish a rotor flux oriented control algorithm. Experimental results show the effectiveness of the proposed controller.
Implantation of corporate social responsibility measures in the horticulture in Mexico and Spain

This work presents the results of a survey, following the Delphi methodology, to experts from the horticultural sector of Mexico and Spain. Interactions with experts have made it possible to identify relevant aspects where the level of consensus is high about the proliferation of Corporate Social Responsibility (CSR) initiatives in the export sector of both countries, standing out: the horticultural sector's leadership in the implementation of standards, which responds to the demand for destination supermarkets in the US and Europe, which despite their particularities, have similar dynamics. Not implementing is considered a risk factor; the implementations are positive actions, which enhance the reputation of companies. Agricultural companies that have a lack of business culture, ignorance, and high administrative burden limit their development, especially among smaller production companies. The greatest progress has been made in the area of labor and environmental practices, areas where consumer concern is growing. Despite CRS initiatives are not providing an immediate benefit to companies, strategic spending is valued. The research is completed with a SWOT analysis (Weaknesses, Threats, Strengths and Opportunities), providing a valuable ranking of great interest for the design of competitive improvements. Highlights Corporate Social Responsibility (CRS) measures in the horticultural activity are driven mainly for the Supermarkets Chains. There are other factors to implement it: gain competitive advantage, improve the reputation of the sector, stay in the market. The Delphi Method is a useful instrument to identify advantages, limitations, and barriers to adopt food safety and Social Responsibility Standards in the global value chain in the agricultural sector. The horticultural activity is adopting several CRS standards in order to stay in the market such as: GRASP, FAIR TRADE, SEDEX, SA 8000. The Delphi Panel considers that the CRS standards and measures implemented improve the labor, environmental and human rights in the horticultural activity in Mexico and Spain.
White Noise Responsiveness of an AlN Piezoelectric MEMS Cantilever Vibration Energy Harvester

This paper reports the design, analysis and experimental characterisation of a piezoelectric MEMS cantilever vibration energy harvester, the enhancement of its power output by adding various values of end mass, as well as assessing the responsiveness towards white noise. Devices are fabricated using a 0.5 μm AlN on 10 μm doped Si process. Cantilevers with 5 mm length and 2 mm width were tested at either unloaded condition (MC0: fn 577 Hz) or subjected to estimated end masses of 2 mg (MC2: fn 129 Hz) and 5 mg (MC5: fn 80 Hz). While MC0 was able to tolerate a higher drive acceleration prior to saturation (7 g with 0.7 μW), MC5 exhibited higher peak power attainable at a lower input vibration (2.56 μW at 3 ms−2). MC5 was also subjected to band-limited (10 Hz to 2 kHz) white noise vibration, where the power response was only a fraction of its resonant counterpart for the same input: peak instantaneous power >1 μW was only attainable beyond 2 g of white noise, whereas single frequency resonant response only required 2.5 ms−2. Both the first resonant response and the band-limited white noise response were also compared to a numerical model, showing close agreements.
Site and land-use associations of soil bacteria and fungi define core and indicative taxa

ABSTRACT Soil microbial diversity has major influences on ecosystem functions and services. However, due to its complexity and uneven distribution of abundant and rare taxa, quantification of soil microbial diversity remains challenging and thereby impeding its integration into long-term monitoring programs. Using metabarcoding, we analyzed soil bacterial and fungal communities at 30 long-term soil monitoring sites from the three land-use types arable land, permanent grassland, and forest with a yearly sampling between snowmelt and first fertilization over five years. Unlike soil microbial biomass and alpha-diversity, microbial community compositions and structures were site- and land-use-specific with CAP reclassification success rates of 100%. The temporally stable site core communities included 38.5% of bacterial and 33.1% of fungal OTUs covering 95.9% and 93.2% of relative abundances. We characterized bacterial and fungal core communities and their land-use associations at the family-level. In general, fungal families revealed stronger land-use associations as compared to bacteria. This is likely due to a stronger vegetation effect on fungal core taxa, while bacterial core taxa were stronger related to soil properties. The assessment of core communities can be used to form cultivation-independent reference lists of microbial taxa, which may facilitate the development of microbial indicators for soil quality and the use of soil microbiota for long-term soil biomonitoring.
Architecture for biological model and database networking

Computational biological models are complex in nature and highly specific. The time invested in developing these complex models has been invaluable, but the goal of code reuse between projects and laboratories has been difficult to achieve. By designing an architecture for biological model and database networking we hope to remedy this problem. Through the use of lightweight CORBA interfaces and well-defined XML namespaces, models can be easily added to the system to expose their interfaces to the group and use data generated by other models. Two simplified versions of models from the heart physiome project are used as examples. Thesis Supervisor: C. Forbes Dewey, Jr. Title: Professor of Mechanical Engineering and Bioengineering
