Genetic organization of the mle locus and identification of a mleR-like gene from Leuconostoc oenos
1996
Characterization of the mle locus harboring the malolactic enzyme gene mleA and malate permease gene mleP from Leuconostoc oenos was completed in this study by mRNA analysis. Northern (RNA) blot experiments revealed a 2.6-kb transcript, suggesting an operon structure harboring mleA and mleP genes. Primer extension analysis showed that the mle operon has a single transcription start site located 17 nucleotides upstream of the ATG translation start site for the mleA gene. We found sequences, TTGACT and TATGAT (which are separated by 18 bp), that are closely related to the gram-positive and Escherichia coli consensus promoter sequences. Upstream of the mleA gene, an 894-bp open reading frame t…
Computation and Display of 3D Movie From a Single Integral Photography
2016
Integral photography is an auto-stereoscopic technique that allows, among other interesting applications, the display of 3D images with full parallax and avoids the painful effects of the accommodation-convergence conflict. Currently, one of the main drawbacks of this technology is the need of a huge amount of data, which have to be stored and transmitted. This is due to the fact that behind every visual resolution unit, i.e. behind any microlens of an integral-photography monitor, between 100 and 300 pixels should appear. In this paper, we make use of an updated version of our algorithm, SPOC 2.0, to alleviate this situation. We propose the application of SPOC 2.0 for the calculation of co…
Silhouette encoding and synthesis using elliptic Fourier descriptors, and applications to videoconferencing
2004
Abstract This paper investigates the use of elliptic Fourier descriptors as a shape descriptor for encoding the silhouette of a person. Shape descriptors are here used for predicting the shape of silhouettes in missing frames within a sequence. This prediction scheme is applied to the case of generating in-between images in a low frame rate videoconferencing system, where the reconstructed silhouette is used as a binary mask for reducing the computational time for the frame reconstruction.
The value proposition of food delivery apps from the perspective of theory of consumption value
2021
Purpose The theory of consumption values (TCV) has successfully explained much consumer choice behavior, but few studies have investigated the values that drive food-delivery application (FDA) use. This study aims to bridge this gap by extending the TCV to the FDA context to examine food consumption-related values and interpreting and rechristening generic consumption values to adapt the TCV to the FDA context. Design/methodology/approach An explorative mixed-method research approach was taken to conduct focus group discussions with 20 target users to develop the questionnaire and then administer it for a cross-sectional survey (pen and pencil) to FDA users aged 22–65 years; 423 complete r…
PMG-Pro: A Model-Driven Development Method of Service-Based Applications
2011
Published version of a chapter published in the book: SDL 2011: Integrating System and Software Modeling. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-25264-8_12 In the Internet of Things, billions of networked and software-driven devices will be connected to the Internet. They can communicate and cooperate with each other to form a composite system. In this paper, we propose PMG-pro (present, model, generate and provide), a language independent, bottom-up and model-driven method for the development of such composite system. We envision that all devices in the Internet of Things provide their functionalities as services. From a service description, a service pre…
Consumer Information Systems as Services
2017
Consumer Information Systems (CIS) are a type of information systems that provides services to consumers instead of addressing users in traditional organizational settings, such as Internet based television. Services typically involve a trade-off between achieving high service productivity and quality. The use of service mass customization to successfully address these issues of both productivity and quality in a service context is proposed. We suggest that the development of Consumer Information Systems as Services (CISaS) may achieve such service mass customization. This paper presents a conceptual framework and investigates how it applies to a set of Internet Protocol Television (IPTV) o…
Media Delivery to Remote Renderers Controlled by the Mobile Phone
2009
In today's content delivery solutions, service delivery and control are still tightly coupled, a service typically being delivered to the same device that controls the session. We present a solution that was designed with the goal to decouple service control and delivery. Using our approach, multimedia streaming services can be delivered to off-the-shelf DLNA devices in visited networks. The service provider receives information about the remote media player and access environment via a mobile phone. Proximity technologies (e.g. barcodes, NFC) of the control device are used for the exchange of required credentials. This paper describes a typical scenario and our prototype implementation.
Unit-level fairness and quality within the health care industry: A justice–quality model
2014
We test a justice–quality model in which peer justice and justice climate are related to the service quality provided by the work unit. Based on the effort–reward imbalance model, we propose that units perceiving fair treatment provide better delivery of the core service (functional service quality) and better relational service beyond the core service (relational service quality). We also test whether the cross-level relationship of high service quality delivered by work units translates into high customer ratings of the service quality they receive. Furthermore, we propose that high service quality increases the work unit’s influence on their customers’ quality of life (QoL). We test thes…
How does information technology– based service degradation influence consumers’ use of services? An information technology–based service degradation …
2019
Information technology is crucial for modern services. Service delivery may include a complex mix of information technology and telecommunication providers, global networks and customers’ information technology devices. This research focuses on service failures that are caused by information technology problems, which we conceptualize as information technology-based service degradation (ITSD). When information technology-based service degradation occurs in a modern service, the information technology problem may originate from the service provider, another partner or any information technology equipment involved. But the customer may not be able to pinpoint the source of the problem immedi…
Logistics service quality: a new way to loyalty
2008
PurposeNow‐a‐days, logistics research focuses on the ability of logistics to deliver a quality service and generate greater satisfaction with the delivered service. Therefore, the aim of this work is to analyze the quality, satisfaction, and loyalty sequence in the logistic service delivery context, with the purpose of considering the role of information and communication technologies (ICT) in this chain of effects.Design/methodology/approachAfter reviewing the different approaches given by the literature, SEM analysis is used to contrast the hypotheses for the analyzed constructs in the presence of high/low ICT level. A questionnaire based on personal survey was conducted among manufacture…
