Data offloading and task allocation for cloudlet-assisted ad hoc mobile clouds

2016

Nowadays, although the data processing capabilities of the modern mobile devices are developed in a fast speed, the resources are still limited in terms of processing capacity and battery lifetime. Some applications, in particular the computationally intensive ones, such as multimedia and gaming, often require more computational resources than a mobile device can afford. One way to address such a problem is that the mobile device can offload those tasks to the centralized cloud with data centers, the nearby cloudlet or ad hoc mobile cloud. In this paper, we propose a data offloading and task allocation scheme for a cloudlet-assisted ad hoc mobile cloud in which the master device (MD) who ha…

The Construction of Ideological and Political Education in Higher Vocational Schools Based on Smartphone Carriers

2022

In the age of technology, artificial intelligence has reached new heights. The growth of the educational system has also evolved with technological growth. In this research, people are going to study the construction of ideological and political education in higher vocational schools based on smartphone carriers. The use of smartphones is becoming more common and unavoidable due to the growth of Internet technology, cloud technology, and wireless technology. The availability of 4G and 5G technologies supports all the relevant and nonrelevant industries to utilize this growth. The field of education has also adapted to this new age of technology by implementing online classes that replace cl…

“La victoria de la técnica”, según Ortega y Gasset (una alternativa a Heidegger)

2013

ABSTRACT Ortega y Gasset's "Mediation on Technique" is part of his historical diagnostic of modern  and contemporary life, wich we can resume by means of the expression "the victory of technique". But, secondly, Ortegian reflections upon technique is decisive for understanding human being, its reason and universal history. And, thirdly, it represents an alternative to the herdeggerian way, not only in relation to technique, but to philosophical thinking in general, although wothout accepting naturalism as way out. RESUMEN “Meditacion de la tecnica” de Ortega y Gasset forma parte del diagnostico historico de la vida moderna y contemporanea, que puede resumirse mediante la expresion “la victo…

Gray visiting Motzkins

2002

We present the first Gray code for Motzkin words and their generalizations: k colored Motzkin words and Schroder words. The construction of these Gray codes is based on the observation that a k colored Motzkin word is the shuffle of a Dyck word by a k-ary variation on a trajectory which is a combination. In the final part of the paper we give some algorithmic considerations and other possible applications of the techniques introduced here.

Implementation of algorithms forK shortest loopless paths

1986

Implementations of loopless k shortest path algorithms are examined. Efficient storage structures for a large number of paths are given. A fast algorithm for determining the shortest paths in Yen's method is developed. Timing experiments show that a hybrid of Clarke's and Yen's methods is generally the fastest, although not significantly. Using upper bounds for the lengths of paths essentially improves all methods.

Los Estereotipos de género en las producciones audiovisuales: diseño y validación de la tabla de análisis EG_5x4

2022

Los productos culturales de la educación no formal, y en concreto los difundidos por televisión y plataformas streaming, incluidas no ficción y animación infantil, proponen entre sus figuraciones personajes estereotipados en su construcción de género. Según investigaciones previas, identificarlos y combatirlos favorece la erradicación de ideas sexistas relacionadas con violencias machistas. Por ello, el objetivo que se planteó fue diseñar y validar una tabla de análisis de estereotipos sexuales presentes en cualquier producto audiovisual. El proceso siguió un protocolo de 3 fases (Garrido et al., 2015): 1) Se revisó la literatura publicada, se extrajeron rasgos relacionados con estereotipos…

Seeking Information on Social Commerce: An Examination of the Impact of User- and Marketer-generated Content Through an Eye-tracking Study

2021

Following the growing popularity of social commerce sites, there is an increased interest in understanding how consumers decide what products to purchase based on the available information. Consumers nowadays are confronted with the task of assessing marketer-generated (MGC) as well as user-generated information (UGC) in a range of different forms to make informed purchase-related decisions. This study examines the information types and forms that influence consumers in their decision-making process on social commerce. Building on uses and gratifications and dual-process theories, we distinguish between marketer and user generated content, and differentiate formats into informational and no…

Identifying the combinations of motivations and emotions for creating satisfied users in SNSs: An fsQCA approach

2020

Social Networking Sites (SNSs) play an important role in our daily lives and the number of their users increases regularly. To understand how users can be satisfied in the complex digital environment of SNSs, this study examines how motivations and emotions combine with each other to explain high satisfaction. Users’ motivations comprise four attributes, entertainment, information, social-psychological, and convenience. Emotions are divided into their two main categories, that is positive and negative emotions. We draw on complexity and configuration theories, present a conceptual model along with propositions and perform a fuzzy-set qualitative comparative analysis (fsQCA). Through an empi…

A Wideband MIMO Channel Model Derived From the Geometric Elliptical Scattering Model

2006

In this paper, we present a reference model for a wideband multiple-input multiple-output (MIMO) channel based on the geometric elliptical scattering model. The model takes into account the exact relationship between the angle of departure (AOD) and the angle of arrival (AOA). Based on this relationship, the statistical properties of the reference model are studied. Analytical solutions are presented for the three- dimensional (3D) space-time cross-correlation function (CCF), the temporal autocorrelation function (ACF), the 2D space CCF, and finally the frequency correlation function (FCF). The correlation properties are studied and visualized under the assumption of isotropic as well as no…
