Euparkeria capensis

description: Euparkeria capensis Broom, 1913 Age. Scythian-Anisian. Occurrence. Cynognathus assemblage zone of the Beaufort Group, South Africa. Diagnosis. Premaxilla with a vertical, dorsally rounded postnarial process. Remarks. Ever since its original description (Broom 1913), Euparkeria (Text-fig. 4a) has played a pivotal role in the discussion of archosaur interrelationships. Long believed to be ancestral to dinosaurs and sometimes birds (Heilmann 1926; Welman 1995), it is now generally considered to be the sister group of the clade comprising all the recent representatives of Archosauria (see Gower and Wilkinson 1996 and references therein). Because of this basal phylogenetic position, its unspecialized morphology and our relatively complete knowledge of its anatomy, Euparkeria is used here as the most basal outgroup to dinosaurs, and it is the taxon used to root the tree.

description: Queueing models in which the services are provided in groups (or blocks or batches) have found to be very useful in real-world applications and such queues been extensively analysed in the literature. In this paper we see one such group service queueing model with balking, reneging and immediate feedback. The arrival processes is a Markovian arrival , where, the arriving customer may balk the system while the server is idle and the pool is empty. Customers are provided service in groups of varying size from 1 to the fixed constant, say, N. The service time of a batch follows the phase type distribution corresponding to the each size of the group. A group’s service time is taken as the highest of the service times of each customers who make up the group. The group of customers who are dissatisfied with the service then that group will get the service immediately. Here, the feedback of a group is defined as the average of the feedback of each customers who make up the group. During the admission period the customers may renege. We calculated the steady state probabilities by using the matrix geometric method, then, by using it we computed few performance measures. We have studied the busy period and the distribution of waiting time is derived. Results are illustrated with some graphical representations.

description: Marasuchus lilloensis (Romer, 1972) Age. Ladinian. Occurrence. Los Chanares Formation, La Rioja, Argentina. Diagnosis. Posterior cervical neural spines project anterodorsally; neural spines of mid- to posterior dorsal vertebrae contact each other dorsally. Remarks. Marasuchus lilloensis is a small carnivorous dinosauriform from the Middle Triassic of South America. The taxon was originally described as a new species of Lagosuchus by Romer (1972) and later even synonymized with the type species of the genus, Lagosuchus talampayensis (Bonaparte 1975). However, Sereno and Arcucci (1994) argued that the holotype of Lagosuchus talampayensis is undiagnostic and consequently referred Lagosuchus lilloensis to a new genus, Marasuchus. Marasuchus is closely related to dinosaurs (Sereno and Arcucci 1994; Novas 1996 «) and is therefore used as an outgroup here. Triassic OTUs

description: Fuzzy graph and Fuzzy soft graph are indispensable computing modules for presenting membership and non membership values in the world of uncertain situations and incidents. In this research article, we introduce the new module of Alternate Quadra Submerging Polar Fuzzy Soft Graph with four co – ordinates with membership and non – membership values. The aim of this new fuzzy soft graph is to find the single output from different uncertain parametric sets of subjects and events, between the range [-1, 1]. The submerge level of fixed four co ordinates is a tool to find the precise and reliable membership degree values from uncertain problems and outcomes. In this artifact, we also investigate the different types of Alternate Quadra Submerging Polar Fuzzy Soft Graphs, corresponding parametric fuzzy values and submerge membership and non – membership values. We discussed Strong, Complete, Complement and m complement properties of Alternate Quadra Submerging Polar Fuzzy Soft Graphs. We use this fuzzy soft graph in the Analysis of water related diseases to find the result of most and least affected diseases with the symptoms among the hostel students in the same locality. We find the maximum and minimum membership and non membership value of the water related diseases in an unique way by using this Alternate Quadra Submerging Polar Fuzzy Soft Graph score function values.

description: After a brief review of the quark-based model for nuclear matter, and some pion properties in medium presented in our previous works, we report new results for the pion valence wave function as well as the valence distribution amplitude in medium, which are presented in our recent article. We find that both the in-medium pion valence distribution and the in-medium pion valence wave function, are substantially modified at normal nuclear matter density, due to the reduction in the pion decay constant.

description: This thesis proposes nonparametric methods for the estimation of univariate density in a unit interval, as well as bivariate copula density. A unified Bayesian framework is proposed for choosing the optimal kernel function and bandwidth. The results of the simulation studies establish the finite sample performances of proposed methods relative to existing counterparts. Relative to existing methods, the proposed methods are shown to adequately estimate the univariate probability density of recovery rates of financially distressed firms and bond issuers. Additionally, the proposed copula has superior tail risk forecasts of All Ordinaries index returns conditional on S&P 500 index returns.

description: Businesses typically entice customers with alluring offers and discounts. Encouraged arrivals is the name given to these curious clients. In certain situations, the service offered by queuing models, notably in transportation networks, enables the simultaneous serving of several consumers. In general, closed-form solutions to bulk service queuing models with idle servers are difficult to find. By coordinating the operations at each workstation using the Chapman-Kolmogorov research technique, the main objective of this study is to assess the performance of the car assembly line in order to reduce waiting times. The server is in a busy state, is idle, is regularly busy, and is in a busy state when it breaks down. Performance metrics are being tracked using a multiple working vacation approach. In this study, analysis of encouraged arrival multiple working vacation queuing model under the steady state condition. In this model, we included encouraged arrival. By resolving difference equations and Chapman Kolmogorov balancing equations, the steady state queue size problem is found. Additionally, the server is in the busy, idle state, regular, and breakdown busy states, and performance metrics are conducted. The server was sent for repair and is now completely repaired to avoid the crash at any time. After that, the server continues to offer the service. It is evidently identified that the efficiency level increased while the encouraged arrival is incorporated. The main contribution of this paper is to show the server is in the busy, idle state, regular, and breakdown busy states, and performance metrics efficient level increases. It is found that they offer more efficient results when compared with the Poisson process method.

description: Recently, in the reconstruction of bone defects, more rapid bone regeneration is needed to achieve osseointegration of the implant and recover function. Although autogenous bone is known as the gold standard because of its excellent osteogenic effect and biocompatibility, it also has the downside of having a harvest limitation and requiring additional surgery at the donor site. To complement this, allogeneic bone, xenogenic bone and synthetic bone have been developed, and in recent years, grafting material using an extracted tooth has been developed and used clinically. In addition, we can apply the methods to promote the reduction of healing period and surgical site pain and osteoblast differentiation. It has been reported that polydeoxyribonucleotide (PDRN) could play the role of stimulating osteoblast growth when used for reconstruction of a bone defect, reducing pain and healing time.

description: In classical Hodgkin lymphoma (cHL), responsiveness to immune-checkpoint block?ade (ICB) is associated with specific tumor microenvironment (TME) and peripheral blood features. The role of ICB in nodular lymphocyte predominant Hodgkin lym?phoma (NLPHL) is not established. To gain insights into its potential in NLPHL, we compared TME and peripheral blood signatures between HLs using an integrative multiomic analysis. A discovery/validation approach in 121 NLPHL and 114 cHL patients highlighted >2-fold enrichment in programmed cell death-1 (PD-1) and T-cell Ig and ITIM domain (TIGIT) gene expression for NLPHL versus cHL. Multiplex imaging showed marked increase in intra-tumoral protein expression of PD-1+ (and/or TIGIT+) CD4+ T-cells and PD-1+CD8+ T-cells in NLPHL compared to cHL. This included T-cells that rosetted with lymphocyte predominant (LP) and Hodgkin Reed–Sternberg (HRS) cells. In NLPHL, intra-tumoral PD-1+CD4+ T-cells frequently expressed TCF-1, a marker of heightened T-cell response to ICB. The peripheral blood signatures between HLs were also distinct, with higher levels of PD-1+TIGIT+ in TH1, TH2, and regulatory CD4+ T-cells in NLPHL versus cHL. Circulating PD-1+CD4+ had high levels of TCF-1. Notably, in both lymphomas, highly expanded populations of clonal TIGIT+PD-1+CD4+ and TIGIT+PD-1+CD8+ T-cells in the blood were also present in the TME, indicating that immune-checkpoint expressing T-cells circulated between intra-tumoral and blood compartments. In in vitro assays, ICB was capable of reducing rosette formation around LP and HRS cells, suggesting that disruption of rosetting may be a mechanism of action of ICB in HL. Overall, results indicate that further evaluation of ICB is warranted in NLPHL.

We apply the results of our companion paper, which derives the complete set of fourth-order Lindblad dissipators using Keldysh methods, to show that resonator gain and loss are substantially affected by dephasing-assisted dissipative processes in the quantum-dot system. These additional processes, which go beyond recently proposed polaronic theories, are in good quantitative agreement with experimental observations

description: Relational event data, which consist of events involving pairs of actors over time, are now commonly available at the finest of temporal resolutions. Existing continuous-time methods for modeling such data are based on point processes and directly model interaction "contagion," whereby one interaction increases the propensity of future interactions among actors, often as dictated by some latent variable structure. In this article, we present an alternative approach to using temporal-relational point process models for continuous-time event data. We characterize interactions between a pair of actors as either spurious or that resulting from an underlying, persistent connection in a latent social network. We argue that consistent deviations from expected behavior, rather than solely high frequency counts, are crucial for identifying well-established underlying social relationships. This study aims to explore these latent network structures in two contexts: one comprising of college students and another involving barn swallows.

Strongly heterodont dentition, with leaf-shaped anterior maxillary tooth crowns; ventral process of the postorbital flexed sharply anteriorly in its lower part. Remarks. Eoraptor (Text-fig. 4d) is one of the oldest and most primitive dinosaurs known to date, but preliminary cladistic analyses indicate that it is a member of the Theropoda (Sereno et al. 1993), although this is not yet generally accepted (Holtz 1995a; Holtz and Padian 1995; Langer 2001). The taxon is represented by two almost complete skeletons (Sereno et al. 1993; Sereno, pers. comm. 1997), and a detailed description of its anatomy is presently under way by P. Sereno.

description: We revisit the phase diagram of spin-1 $su(2)_k$ anyonic chains, originally studied by Gils {\it et. al.} [Phys. Rev. B, {\bf 87} (23) (2013)]. These chains possess several integrable points, which were overlooked (or only briefly considered) so far. Exploiting integrability through a combination of algebraic techniques and exact Bethe ansatz results, we establish in particular the presence of new first order phase transitions, a new critical point described by a $Z_k$ parafermionic CFT, and of even more phases than originally conjectured. Our results leave room for yet more progress in the understanding of spin-1 anyonic chains.

description: This study examines a two-way communication retrial queue with collision and working breakdown. Retrial incoming calls may interfere with service if the server is busy with primary incoming calls. Arriving primary incoming calls are sent to the orbit while the server is busy or enter for service if the server is discovered to be idle. The server places calls while it is idle. Incoming calls are given high priority, and outgoing calls are given low priority. During regular service, the system may fails at any time. The server will continue to provide service after a breakdown even though at a slower rate rather than shutting down completely. We assume that outgoing calls and service time distributions are modelled in terms of various PH distributions, while incoming calls are assumed to follow a Markovian arrival process (MAP). The matrix-analytic approach will be used to investigate the resulting QBD process in steady state. Some of the performance metrics’ calculations have been figured out. At the end, the results are presented in both numerical and graphical form.

Gojirasaurus quayi

description: Gojirasaurus quayi Carpenter, 1997; metataxon Age. Norian. Occurrence. Cooper Canyon Formation of the Dockum Group, New Mexico, USA. Diagnosis. Differs from Coelophysis and Lilienstemus in the greater relative height of the neural spines of the mid to posterior dorsals; from Eoraptor, Herrerasaurus, and Staurikosaurus in the elongation of the dorsal vertebrae and the presence of a small lateral projection on the distal end of the tibia; and from Procompsognathus in the significantly larger overall size. There are no elements that can be compared with known remains of Shuvosaurus (see comments below). Remarks. The holotype material of Gojirasaurus was first described as ‘procompsognathid indet.’ by Parrish and Carpenter (1986), and only later designated as the holotype of a new taxon of theropod (Carpenter 1997). The presence of a premaxilla of the edentulous theropod Shuvosaurus in the same quarry as the type of Gojirasaurus is interesting (Parrish and Carpenter 1986, fig. 11.8; Carpenter 1997). The holotype skull of Shuvosaurus is approximately 17 cm long (Chatterjee 1993), but represents a juvenile individual, indicating that adult Shuvosaurus would have been among the largest known Triassic theropods. Since the holotype of Gojirasaurus represents the largest theropod postcrania known from the Triassic of North America (Carpenter 1997), it seems quite possible that Gojirasaurus quayi Carpenter, 1997, might be a junior synonym of Shuvosaurus inexpectatus Chatterjee, 1993. However, given the uncertain association of the remains, and the lack of comparable elements in the holotype specimens, both taxa are treated separately here.

Essays on the corporate bond market
Creators: name: Wei, Xiaoting
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: This thesis investigates the impact of three corporate events on corporate bond prices in the U.S. Specifically, the first empirical essay examines whether bond prices exhibit delayed reactions to earnings announcements. The second essay examines whether bond prices react to equity analysts’ recommendation revisions and the third essay examines whether bond prices react to unexpected dividend changes. The results from the first essay show that the bond price reactions to earnings news are asymmetric, with greater reactions following negative earnings surprises than following positive earnings surprises. This is consistent with the Black–Scholes (1973) bond pricing model. Bond price reactions are also reported to be affected by bond risk. Because issuers of riskier bonds are more likely to face default, earnings news is reported to be more pertinent to the value of riskier bonds. The second essay reports similar asymmetric bond price reactions. The bond price reactions appear to be directed more towards recommendation downgrades than towards upgrades. In addition, riskier bonds tend to exhibit stronger reactions to recommendation revisions than safer bonds do. The third essay documents significant and negative bond price reactions to dividend cuts and the significant reactions of speculative-grade (riskier) bonds to dividend changes. The bond price changes are in the same direction as the dividend changes are, which supports the dividend information content hypothesis rather than the wealth expropriation hypothesis, which would predict opposite bond price reactions.

description: A maximum likelihood methodology for the parameters of models with an intractable likelihood is introduced. We produce a likelihood-free version of the stochastic approximation expectation-maximization (SAEM) algorithm to maximize the likelihood function of model parameters. While SAEM is best suited for models having a tractable "complete likelihood" function, its application to moderately complex models is a difficult or even impossible task. We show how to construct a likelihood-free version of SAEM by using the "synthetic likelihood" paradigm. Our method is completely plug-and-play, requires almost no tuning and can be applied to both static and dynamic models. Four simulation studies illustrate the method, including a stochastic differential equation model, a stochastic Lotka-Volterra model and data from $g$-and-$k$ distributions. MATLAB code is available as supplementary material.

description: In many industries, ensuring compliance in business processes has become a cost-intensive task due to intensive regulation. For companies to operate profitably despite current regulatory developments, approaches to the economic assessment and analysis of process-based compliance measures are needed. The dissertation entitled “Economic Assessment and Analysis of Business Process Compliance: An Approach based on Basic Control Flow Patterns and Extensible Event Streams” addresses that need by designing, implementing, and evaluating: 1) a mathematical method for the economic assessment of BPC drawing on patterns of basic control flows, and 2) an information technology-based method for the economic analysis and selection of compliance measures drawing on eXtensible Event Streams. This paper is an extended abstract of the dissertation, which briefly presents the two methods. Its conclusion discusses the implementation of a software artifact and the results of a summative evaluation.

description: Extropy is a complimentary dual of Shannon’s entropy, which has many applications. The maximum likelihood and Bayesian approaches are used in this article to explore the weighted extropy and weighted residual extropy of the Pareto type II distribution. Using unified hyper-censoring data, we calculate the maximum likelihood estimation of weighted extropy and its residual measures. Based on symmetric and asymmetric loss functions, Bayesian estimators of weighted extropy and its residual measure are developed based on unified hyper censoring data. To do some complex calculations, Markov chain Monte Carlo methods are used. To test the performance of the estimators, a Monte Carlo simulation study and an illustration using real data sets were carried out. The outcomes of the study showed that as the sample size increases, maximum likelihood and Bayesian estimators of the weighted extropy and its residual measure perform well. Also, Bayesian estimators of the weighted extropy and its residual under the general entropy loss function are superior to the Bayesian estimators under the others in most cases. Theoretical and empirical findings are generally in good agreement.

description: Recent technical advances have sparked renewed interest in physical systems that couple simultaneously to different parts of the electromagnetic spectrum, thus enabling transduction of signals between vastly different frequencies at the level of single photons. Such hybrid systems have demonstrated frequency conversion of classical signals and have the potential of enabling quantum state transfer, e.g., between superconducting circuits and traveling optical signals. This article describes a simple approach for the theoretical characterization of the performance of quantum transducers. Given that, in practice, one cannot attain ideal one-to-one quantum conversion, we explore how well the transducer performs in scenarios ranging from classical signal detection to applications for quantum information processing. While the performance of the transducer depends on the particular application in which it enters, we show that the performance can be characterized by defining two simple parameters: the signal transfer efficiency $η$ and the added noise $N$.

Herrerasaurus ischigualastensis

description: Herrerasaurus ischigualastensis Reig, 1963 Age. Camian. Occurrence. Ischigualasto Formation, San Juan, Argentina. Diagnosis. Large premaxillary-maxillary fenestra; dorsal part of supratemporal fenestra less than half as wide as ventral part; pronounced suborbital ridge on the jugal; lateral depression on quadratojugal process of squamosal; very slender posterior dorsal process of the dentary. Remarks. In 1963, Reig described three taxa of saurischian dinosaurs from the Ischigualasto Formation of Argentina as Herrerasaurus ischigualastensis, Ischisaurus cattoi, and Triassolestes romeri. Herrerasaurus (Text-fig. 4e) received relatively little attention until the discovery of a complete skeleton in the late 1980s (Sereno and Novas 1992). The osteology of this taxon was described in detail in a series of papers by Novas (1993), Sereno (1993) and Sereno and Novas (1993). The type specimens of Ischisaurus and Triassolestes, and other theropod specimens from the Ischigualasto Formation described as Frenguellisaurus ischigualastensis by Novas (1986), and cf. Staurikosaurus sp. by Brinkman and Sues (1987), respectively, were referred to Herrerasaurus ischigualastensis (Novas 1993).

description: Load sharing systems have the ability to distribute the workload among its components. For analyzing a two component parallel load sharing system, the accelerated failure time (AFT) based model with component lifetimes as linear failure rate distribution have been recently proposed in the literature. In the present study, the component lifetimes are assumed to follow a modified Weibull distribution, which is the generalization of many standard lifetime distributions such as exponential, Weibull, Rayleigh, and linear failure rate. The use of modified Weibull distribution leads to a new family of bivariate distributions for ordered random variables. We have also looked into the associated inference techniques for the proposed model. In order to evaluate the effectiveness of the suggested estimating approaches, we conducted a simulation study. In order to provide a practical application and better understanding, we carefully examine a dataset related to motors.

description: Diese Arbeit stellt Konzepte vor, die im Kontext zustands- oder objektbasierter Systeme die gemeinsame Behandlung von Implementierungssprachen und Spezifikationssprachen gestatten. Sie befaßt sich zum einen mit der formalen Definition einer Programmiersprache und zum anderen mit dem Entwurf einer Spezifikationssprache, die auf die Programmiersprache ausgerichtet ist. Abhängigkeiten zwischen diesen beiden Aspekten werden herausgearbeitet. Die Definition beider Sprachen erfolgt auf einem eigenständigen Berechnungsmodell, einer formal definierten abstrakten Maschine, zur Modellierung des Verhaltens von Objekten. Erweiterungen des Berechnungsmodells, die Rekursion, Verschachtelung von Programmeinheiten oder Typfragen betreffen, werden vorgestellt. Zur Spezifikation zustandsbasierter Systeme wird dynamische Logik, eine Erweiterung einer Prädikatenlogik erster Stufe, die Zustände explizit macht, eingesetzt. Mit Hilfe der dynamischen Logik kann das Verhalten von Objekten abstrakt beschrieben werden. Ein Beweissystem für die Logik wird definiert, mit dem auch die Verifikation einer Implementierung bezüglich einer Spezifikation möglich ist. Hierzu wird ein Korrektheitsbegriff definiert, der durch das Beweissystem operationalisiert wird. Zur Beschreibung von modularen Software-Systemen werden formale Parametrisierungs- und Schnittstellenkonzepte erarbeitet. Eine Reihe von Relationen wird definiert, die es ermöglichen, verschiedene Beziehungen zwischen Systemkomponenten zu modellieren. Horizontale und vertikale Entwicklung wird betrachtet.

description: In this paper, we present the four-stage concept, implementation, application, and 2-stage evaluation of the tool EconBPC. EconBPC is a software artifact that emerged from a design science research initiative on the use of extensible event streams (XES). It was created to take a first step towards an automated activity-based monetary assessment of security and compliance measures in business processes and their addressee-oriented representation in a compliance view. For this purpose, EconBPC provides users with annotation features for XES and compliance processes, enables the storage of annotated log files, and the comparison of expenses for security and compliance activities with costs from associated regulatory breaches.
The role of perceived brand congruency, team identification and perceived community concern in sports brand alliances

description: Sports teams are attractive alliance partners for brands looking to enhance their sales potential and differentiate themselves in highly competitive markets. Whilst such brand alliances provide many benefits, they may also expose the partnering brands to risk. This is particularly so when the alliance partner is a potentially undesirable brand (e.g., offers products or services that have the potential to harm vulnerable consumers). A conceptual model comprising the Social Dilemma Perspective and Fan Identity Theory was therefore developed to examine if preferences for brand alliances involving compatible alliance partners (CAPs) or potentially undesirable brand (PUBs) varied by sports fans’ team identification and perceived community concern. Specifically, this study examined whether team identification and perceived community concern moderated the mediating effect of perceived brand congruency on the relationship between perceptions of brand alliance partners and sports fans’ evaluations of, and behavioural intentions towards, brand alliance partners. An exploratory qualitative study involving 20 sports fans and 20 executives from Australian sports teams and their brand alliance partners was used to inform the survey content of a quantitative study comprising 404 Australian sports fans. Findings from this survey did not support the integrated model comprising Social Dilemma Perspective and Fan Identity Theory. That is, sports fans with low team identification were more, as opposed to less, likely to support their team’s brand alliance partners relative to those with high team identification. Four drivers of perceived brand congruency were also identified: familiarity with a brand alliance partner, the perceived reputation of a brand alliance partner, the extent to which a brand alliance partner is involved in the activities of the sports team, and brand communication from the brand alliance partner. Also identified were three components of brand congruency, as follows: perceived brand fit, perceived product fit, and perceived cause fit. Perceived community concern, a novel theoretical construct, and team identification were then found to moderate the mediating effect of perceived brand congruency with respect to the relationship between perceptions of brand alliance partners and behavioural intentions towards, and evaluations of, brand alliance partners. Finally, the impact of perceived brand congruency was found to differ as a function of whether the brand alliance featured a PUB or a CAP. From a managerial perspective, these findings highlighted how the brand managers of sports teams and commercial brands can select alliance partners that will maximise the value of potential brand alliances. Additionally, the findings highlighted the need for regulations governing the formation of brand alliances with PUBs or public information campaigns to warn about the impacts of brand alliances with PUBs.

description: In this article an attribute control chart is designed for the Exponentiated Inverse kumaraswamy distribution under a time truncated life test by assuming the life-time of the item follow the selected Exponentiated Inverse Kumaraswamy distribution with known parameters. In order to limit the cost of checking the quality of an item in any industrial process with time truncation, this process is much useful. By considering the average number of defective items from a specified lot that are failed before the time limit, the attribute control limits are constructed. The control chart is determined using Binomial distribution based on the Upper and Lower control limits. The functioning of the designed control chart is examined with the average run length (ARL) values. The control chart constants and limits are calculated for specific ARL values with assumed parameters at different sample sizes for an in-control process. These control chart constants are obtained by considering different combinations of parameters of the assumed distribution. With these in-control limits the ARL values are observed by shifting the parameter values. A simulation analysis is developed by taking a specific number of observations in each sample and the average number of failures from each sample is considered as a statistic to establish the execution of the control chart for a specified ARL at a particular shift in parameter. With that statistic of average number of failures from the samples the control chart is prepared. It is observed a specific change in defective number when there is shift in parameter values. The results are illustrated with an example.

description: We describe a new pushbroom hyperspectral imaging device that has no macro moving part. The main components of the proposed hyperspectral imager are a digital micromirror device (DMD), a CMOS image sensor with no filter as the spectral sensor, a CMOS color (RGB) image sensor as the auxiliary image sensor, and a diffraction grating. Using the image sensor pair, the device can simultaneously capture hyperspectral data as well as RGB images of the scene. The RGB images captured by the auxiliary image sensor can facilitate geometric co-registration of the hyperspectral image slices captured by the spectral sensor. In addition, the information discernible from the RGB images can lead to capturing the spectral data of only the regions of interest within the scene. The proposed hyperspectral imaging architecture is cost-effective, fast, and robust. It also enables a trade-off between resolution and speed. We have built an initial prototype based on the proposed design. The prototype can capture a hyperspectral image datacube with a spatial resolution of 192x192 pixels and a spectral resolution of 500 bands in less than thirty seconds.
