Developments in Business Simulation & Experiential Exercises , Volume 9 , 1982 12 THE USE OF SIMULATION TO TEST THEORIES OF BARGAININC IN A BUSINESS CONTEXT

The purpose of this research is to demonstrate how simulation can be used to empirically test theories of bargaining in a business context. Business negotiations are private, complex and multi-issue; there are thus limitations to investigating them through field study. The advantage of simulation as a theorytesting methodology is that it can provide a rich context while at the same time permit experimental control and measurement. In particular, this research demonstrates how simulation can be used to test a gametheoretic model of bargaining. The experiment reported here is highlighted by the use of multiattribute preference measurement and an experimental design that allows a rigorous test of the game-theoretic model as well as unconfounded estimation of bargaining skill and situational power effects. The results of this research support the game theoretic model. Implications for educators and practitioners are discussed.
Cooperative credit banks: some fundamental institutional features

The aim of this paper is to analyze individual preferences in relation to different job characteristics. This is an important issue in the light of the huge literature in labor economics and human resource management about the impact of monetary and nonmonetary incentives on understanding workers’ performance and well-being. More specifically, this work considers the case of employees in cooperative credit banks located in Campania; the research is carried out applying a conjoint analysis approach on stated preference data. Novel features of the analysis include the application of this approach to empirical research on worker incentives, particularly in the cooperative sector; and the utilization of a mixed logit model to allow for heterogeneous individual tastes.
Basal metabolic rate and the mass of tissues differing in metabolic scope: Migration-related covariation between individual knots Calidris canutus

To examine whether variability in the basal metabolic rate (BMR) of migrant shorebirds is a function of a variably sized metabolic machinery or of temporal changes in metabolic intensities at the tissue level, BMR, body composition and activity of cytochrome-c oxidase (CCO, a marker for maximum tissue respiration) were measured in 14 captive Knots Calidris canutus islandica in late spring, during the period of mass loss after the migratory body mass peak. Although the body mass cycle of captive birds closely followed the changes of free-living conspecifics, their fat-free mass of muscles and organs was somewhat lower and their fat content higher. BMR significantly declined during mass loss, as did the fat-free dry mass. BMR was an allometric function of both body mass (exponent=0.687) and lean dry mass (exponent=1.132). Fat-free dry mass of heart sind flight muscle decreased with the loss of fat. CCO-activity was determined in heart, flight muscle, leg muscle, liver and kidney. It was highest in heart and flight muscle and low in the other tissues. CCO-activity was not correlated with total fat mass. Intraspecific migration-related variation in BMR seems better explained by variation in the mass of organs with a high metabolic scope (as indicated by high CCO-activity), than by variation in the intensity of tissue metabolism.
NSGA-II for Parallel Machine Scheduling with Tardiness and Extra QoS Cost Considerations

We investigate parallel machine scheduling problem of matching the orders and factories with the multiobjective of minimizing the total tardiness and the extra quality of service (QoS) cost in this work. We establish a multi-objective integer programming (MOIP) model, and devise an epsilon constraint ($\boldsymbol{\varepsilon}$-constraint) algorithm together with Non-dominated Sorting Genetic Algorithm II (NSGA-II). The $\boldsymbol{\varepsilon}$-constraint method produces exact solutions for small order instances, while the NSGA-II can efficiently solve large-scale instances. Numerical experiments validate the proposed model and algorithms.
Attack Surface Identification and Reduction Model Applied in Scrum

Today's software is full of security vulnerabilities that invite attack. Attackers are especially drawn to software systems containing sensitive data. For such systems, this paper presents a modeling approach especially suited for Serum or other forms of agile development to identify and reduce the attack surface. The latter arises due to the locations containing sensitive data within the software system that are reachable by attackers. The approach reduces the attack surface by changing the design so that the number of such locations is reduced. The approach performs these changes on a visual model of the software system. The changes are then considered for application to the actual system to improve its security.
Detailed Analysis and Understanding of the Transport Mechanism of Poly-Si-Based Carrier Selective Junctions

We investigate the transport mechanism of poly-Si-based carrier-selective junctions using the two-dimensional numerical semiconductor device simulations. The detailed transport model considers the charge carrier transport through the pinholes as well as tunneling through a very thin silicon oxide simultaneously. For the verification of the simulation model, the complete temperature dependent transfer length method is modeled and its results are verified with measurements of two different samples. By means of rigorous simulations, the influence of different pinhole geometrical and material parameters on junction resistivity are investigated and explained in detail. From the presented results, the fundamental understanding needed for optimizing the poly-Si-based carrier selective junction in respect to the main design parameters such as doping level in poly-Si, annealing time, silicon oxide thickness, and pinhole density is given. The detailed analysis shows the pinhole channel plays the most crucial role in the design of poly-Si-based carrier-selective junctions if the silicon oxide layer thickness is larger than 2 nm.
A Measurements Based Characterization of Fading in Indoor Millimeter-Wave Distributed Antenna Systems

In this paper, we empirically investigate the effects of shadowing and multipath fading upon the user equipment (UE) to access point (AP) channels found in indoor distributed antenna systems (DAS) at 60 GHz. Our measurements have considered the signal power simultaneously received at 9 ceiling locations which are likely to be used in future indoor millimeter-wave DAS deployments. During the experiments, a single user imitated making a voice call on a UE, which acted as the transmitter, while walking through an indoor office environment. To characterize the shadowing and multipath fading, we have made use of the lognormal and κ-µ distributions respectively.
Pegxit: Evidence from the Classical Gold Standard

We develop a simple model that highlights the costs and benefits of fixed exchange rates as they relate to trade, and show that negative terms-of-trade shocks reduce fiscal revenue and increase the likelihood of an expected currency devaluation. Using a new high frequency data set on commodity-price movements from the classical gold standard era, we then show that the model’s main prediction holds even for hard pegs. We identify a negative causal relationship between export-price shocks and currency-risk premia in emerging market economies, indicating that negative commodity-price shocks increase the likelihood of abandoning their hard pegs.
Prediction of Manipulation, Empathy and Social Irritability through Selected Personality Traits among Managers

The contribution analyzes manipulation, empathy and social irritability through verification of predictive power personality traits (sociability, emotional stability and self-confidence). The research sample is based on head officers and managers in Bratislava and Presov County, working in both private and public organisations. The aim of the study is to analyze predictive power of selected personality traits to manipulation, empathy and social irritability. The research data were collected through BIP questionnaire (Bochum Personality Questionnaire) in slovak translation by Džuka (2002) and MESI questionnaire (Manipulation, Empathy and Social irritability) by Frankovský and Birknerova (2014). Base on the confirmed aspects we came to the conclusion that sociability and self-confidence have significant predictive power in predicting manipulation. Sociability and emotional stability do not have significant power in predicting empathy. Sociability has significant predictive power in predicting social irritability but on the other hand self-confidence does not have significant predictive power in predicting social irritability.
Additively Manufactured Circular-Linear Polarization Converter using Circular Waveguide

This paper details the design of a novel circular-linear polarization converter using circular waveguide with elliptical corrugations to be constructed using additive manufacturing, making use of the technique’s ability to create otherwise difficult geometries and rapid prototyping capabilities. The designed converter has under 1 dB of insertion loss and below 20 dB cross-polarization in its operating band.
Influence of the ZnO Nanostructures Shape on Piezoelectric Energy Harvesters Performance

Due to the small size and ability to supply energy to remote devices, metal–oxide-based piezoelectric energy harvesters have recently gained an enormous amount of attention. The nanostructure of the piezoelectric metal–oxide profoundly influences the operational characteristics of these devices. Here, the effect of geometrical parameters of various ZnO nanostructures, i.e., nanowire (NW), nanotube (NT), and nanoneedle (NN), on their mechanical resonance frequency, piezoelectric voltage, and output power is investigated at different load resistances through COMSOL simulations. The geometrical parameters considered in the simulations are in the range of those obtained from experimental works: 1–3- $\mu \text{m}$ height for all nanostructures, 50–150 nm for NWs cross section, and a few tens of nanometer for NT hollow cores and NN tips. Results show as the nanostructures are made thinner and longer, better piezoelectric performance is observed. At a constant pressure of 10 N/m2, open-circuit piezoelectric voltages of 37.88, 154.56, and 599.23 mV are achieved from the champion NWs, NTs, and NNs, respectively. The respective maximum output powers of these nanostructures are 0.58, 1.93, and 2.6 mW/cm2. The analytical equations of the moment of inertia ( ${I}$ ) for all of these nanostructures are extracted, and the superior performance of NNs is attributed to a lower moment of inertia. The load resistance significantly impacts the mechanical resonance frequency, piezoelectric voltage, and output power of these nanostructures; the effect is described by deriving and analyzing the Mason equivalent circuits.
Preserved Knowledge Embedding Question : Why does the person have an umbrella ? Answer : It is raining . Knowledge Incorporated Open-Domain VQA Candidate Knowledge Retrieval Dynamic Memory Network Memory Updating Attention Machanisim Query

Visual Question Answering (VQA) has attracted much attention since it offers insight into the relationships between the multi-modal analysis of images and natural language. Most of the current algorithms are incapable of answering open-domain questions that require to perform reasoning beyond the image contents. To address this issue, we propose a novel framework which endows the model capabilities in answering more complex questions by leveraging massive external knowledge with dynamic memory networks. Specifically, the questions along with the corresponding images trigger a process to retrieve the relevant information in external knowledge bases, which are embedded into a continuous vector space by preserving the entity-relation structures. Afterwards, we employ dynamic memory networks to attend to the large body of facts in the knowledge graph and images, and then perform reasoning over these facts to generate corresponding answers. Extensive experiments demonstrate that our model not only achieves the state-of-the-art performance in the visual question answering task, but can also answer open-domain questions effectively by leveraging the external knowledge.
Multipactor Discharge in High Power Microwave Systems: Analyzing Effects and Mitigation through Simulation in ICEPIC

Abstract : Single surface multipactor in high power microwave systems was investigated computationally and analytically. The research focused upon understanding the cause and parametric dependence of the multipactor process leading to suggested methods of mitigation. System damage due to reaction was also assessed. All simulations were performed using the PIC code developed by AFRL, known as ICEPIC. In recreating the susceptibility curves that define regions of multipactor growth and decay, a discrepancy was found between previous published results and those observed in the current simulation. This was attributed to previous simulations not accounting for the magnetic component in the electromagnetic radiation incident on the dielectric window. By surveying different static magnetic and electric fields both parallel and perpendicular to the dielectric, revised susceptibility curves were determined. An analytic method confirmed the origin of the discrepancy. The reflection of the waveguided radiation by the multipactor electrons degrades the output and may damage the microwave source. A theory for the reflection resulting from multipactor was derived to aide in quantifying reflection. A plane wave was used to model incoming microwave radiation and the amplitude of the electric field in reflected and transmitted waves was measured for various frequencies of the incident plane wave.
3D Printed Modular Origami Inspired Dielectrics for Frequency Tunable Antennas

We explore the impact of origami structure meta-materials on electromagnetic devices. Here two modular origami-inspired dielectric structures were fabricated by 3D printing with the ability to shift the resonant frequency of patch antennas operating at approximately 1 GHz. Tunablity was achieved by deploying different dielectric origami configurations that were actuated to control the degree of folding or compression when placed on top of a standard patch antenna. The measured effects of the dielectric origami structure is to provide a 2% range of tunability of the antenna resonance frequency, with simulations showing a similar trend as experiments. The demonstration of active tuning by actuation of dielectric origami may find application in future antenna and telecommunication systems.
UWB Rotation Scanning System for Breast Imaging

UWB microwave imaging has been demonstrated to have clinical potentials for breast screening. However, existing imaging system either incorporate commercial VNA or simplify the system by sacrificing bandwidth or ADC accuracy. We proposed a system that equips a rotation mechanism to reduce antenna elements and a line laser for skin surface estimation. We demonstrated the feasibility of the system through silica gel based breast phantom.
A Circular Polarized Four-Beam Antenna for Direction of Arrival Applications at 2.45 GHz

We propose a switched beam circular polarized antenna optimized for operation at 2.45 GHz. It comprises two disc-based patches assembled in a concentric structure. The antenna is capable of four beams: a directive beam with maximum in broadside direction, a conical beam with a transmission zero in ϕ = 0°, and two tilted beams pointing to ϕ = ±30°. The compact dimension, the single-layer structure, and the beamset with moderate beam correlation confirms the effectiveness of the proposed antenna for Direction of Arrival (DoA) applications.
Microwave Imaging Technology for In-line Food Contamination Monitoring

Foreign body contamination in food is one of the major sources of complaints against food manufacturers, and it can lead to injury, loss of brand loyalty and large recall expenses. Different technologies, such as X-ray or infrared techniques, are currently applied to detection systems used for food inspection, but physical contamination, with e.g. wood, plastic, metal and glass fragments, is still present in food. For this reason, there is the interest to develop new technologies able to address the still unmet needs of food industry. In this paper, we report about preliminary investigations of the use of the microwave imaging technology for food contamination monitoring. Numerical results show the feasibility of the proposed approach. The realization of prototype measurement system is under development.
Hybrid Control Strategy of DC-DC Converters Based on Admissible Edge-Dependent Average Dwell Time

In this study, a novel switching rule is designed for DC-DC converters that drive the state of the switched dynamic system to a desired equilibrium point. Utilizing the notion of admissible edge-dependent average dwell time(AED-ADT), the proposed control law handle the chattering problem on the operating point, limit high frequency and decrease the switching loss. The results are given in terms of linear matrix inequalities(LMI). The efficiency of the proposed method is illustrated by simulation.
The Dutch long-term care reform: Moral conflicts in executing the Social Support Act 2015

On 1 January 2015, a new long-term care reform entered into force in the Netherlands, entailing amongst others a decentralization of long-term care responsibilities from the national government to the municipalities by means of a new law: the Social Support Act 2015. Given the often disputed nature of the reform, being characterized on the one hand by severe budget cuts and on the other hand by a normative reorientation towards a participation society, this article examines to what extent municipalities in the Netherlands take (potential) moral conflicts into account in their execution of the Social Support Act 2015. In doing so, the article applies a ‘coherentist’ approach (consisting of both rights-based and consequentialist strands of ethical reasoning), thereby putting six ethical principles at the core (non-maleficence & beneficence, social beneficence, respect for autonomy, social justice, efficiency and proportionality). It is argued that while municipalities are indeed aware of (potential) moral conflicts, the nature of the new law itself leaves insufficient room for municipalities to act in a sufficiently proactive and supportive/empowering manner on these challenges.
Time-to-Collision-Based Awareness and Congestion Control for Vehicular Communications

Vehicular wireless communications require both congestion control to guarantee the availability of a fraction of the bandwidth for safety-related event-driven messages in emergency cases, and awareness control to adapt the beaconing activity to the application needs and surrounding traffic situation. Most current approaches either ignore the traffic situation and only adapt the beaconing rate to the channel congestion state or override the congestion control limits, leading to questionable results in both cases. In this paper, we conceive and validate a novel approach, combining both aspects. Based on distributed Network Utility Maximization (NUM), our algorithm satisfies the constraints on channel availability, whereas the safety of the surrounding traffic situation is captured with a time-to-collision metric, used to assign priorities in the optimal allocation problem. The performance of the proposed approach is validated and compared to other popular algorithms. Results show that our proposal automatically anticipates a potential increase in rate due to a critical safety situation, but does not interfere with the reserved bandwidth for safety applications.
Antimicrobial activity of recombinant E. coli expressed chicken AvBD-2 and its mRNA expression in Indian native Aseel and Kadaknath chicken breeds

Avian b defensins (AvBD) are antimicrobial peptides that play a crucial role in the innate immune response in chickens. In the present study, chicken AvBD2 gene was cloned, expressed in E. coli system and the in vitro antimicrobial activity of recombinant peptide was evaluated. The entire mature peptide region of chicken AvBD2 region was amplified and cloned in pUC29 cloning vector. Further, the coding region was sub cloned in pET-28A expression vector. After transformation in E. coli cells, the peptide synthesis was induced and recombinant protein (7.7 kDa) was purified by using Ni-NTA affinity column. The recombinant chicken AvBD2 showed antibacterial activity against S. Pullorum. The minimum bactericidal concentration (MBC) of recombinant chicken AvBD2 evaluated by micro-broth dilution assay was 35 µg/ ml. We also quantified the expression of AvBD2 transcript expression in day-old spleen tissue of Indian native chicken breeds (Aseel and Kadaknath) and White Leghorn. Measurable AvBD2 mRNA expression was found in the spleen of all three breeds. However, no significant difference was found in AvBD2 gene expression between native chickens and White Leghorn.
Three-Dimensional Bandstop Frequency-Selective Structures Based on Gielis-Shaped Loop Resonator

In this paper, a three-dimensional bandstop frequency-selective structure (FSS) based on Gielis-shaped loop resonator is proposed. A Gielis shape profile for the full and half loop resonator provides a reduction in operating frequency by around 10% compared to a circular profile for a fixed unit cell size. S parameters of an equivalent circuit model for the half Gielis loop unit cell is also discussed.
Chapter 4 Governance Modeling : Dimensionality and Conjugacy

The Q-analysis governance approach and the use of simplicial complexes—type of hypergraph—allow to introduce the formal concepts of dimension and conjugacy between the network of entities involved in governance (typically organizations) and the networks of those attributes taken into account (e.g. their competences), which offer a specific angle of analysis. The different sources of existing data (e.g. textual corpora) to feed the analysis of governance—environmental in particular—are mentioned, their reliability is briefly discussed and the required pre-processing steps are identified in the perspective of evidence-based analyses. Various indices are constructed and evaluated to characterize the context of governance as a whole, at mesoscale, or locally, i.e. at the level of each of the entities and each of the attributes considered. The analysis of ideal-type stylizing boundary cases provides useful references to the analysis of concrete systems of governance and to the interpretation of their empirically observed properties. The use of this governance modeling approach is illustrated by the analysis of a health-environment governance system in Southeast Asia, in the context of a One Health approach.
2D Physical Optics Analysis of the Focal Region of Parallel-Plate Waveguide Lenses

A physical optics (PO) method for computing the focal-region fields of a parallel-plate waveguide (PPW) lens is presented. A simplified delay line model is used to represent the delay section between inner and outer lens profile. The lens is analyzed by assuming a plane wave incident on the outer contour. For a given lens geometry, the resulting maximum field loci at different angles of incidence are reported. The close agreement with full-wave results by a commercial simulator validates the applicability of the underlying two-dimensional (2D) lens model. The developed tool is several orders of magnitude faster than the general purpose full-wave simulation and therefore presents an efficient auxiliary tool for the design of lens feed networks.
