Potential-Field-Based Anycast Routing in Large-Scale Wireless Mesh Networks : A Distributed Algorithm based on Finite Difference Method

In this paper, we propose an anycast routing scheme for large-scale wireless mesh networks, which requires only one-hop local information with no flooding overhead. We develop an analytical model for anycast mesh networks based on an electrostatic theory. A finite difference method contributes to achieving gateway load balancing with constant control overheads. We verify the performance of the proposed scheme by simulations.
nmfgpu4R: GPU-Accelerated Computation of the Non-Negative Matrix Factorization (NMF) Using CUDA Capable Hardware

In this work, a novel package called nmfgpu4R is presented, which offers the computation of Non-negative Matrix Factorization (NMF) on Compute Unified Device Architecture (CUDA) platforms within the R environment. Benchmarks show a remarkable speed-up in terms of time per iteration by utilizing the parallelization capabilities of modern graphics cards. Therefore the application of NMF gets more attractive for real-world sized problems because the time to compute a factorization is reduced by an order of magnitude.
PPP for Advanced Precise Positioning Applications, Including Reliability Bound

The PPP technology is able to complement the basic GNSS functionalities for providing an advanced high accurate PNT solution. PPP algorithms use code and phase observations from a dual-frequency receiver, together with precise satellite orbits and clocks, in order to calculate high accurate receiver coordinates and precise clock estimations. Our GNSS team has developed the algorithms and the infrastructure, except for the tracking network, needed for providing a commercial PPP service. We can manage all the required components, from the real time orbit and clock products generation, to the PPP filter implementation and the service provision. As a differentiating feature, we are working on providing a reliability bound, together with accuracy, continuity and availability to our PPP solution, which we think will help widening its applicability range. In this paper we are going to analyze the PPP problem, trying to understand which the essential limitations of the process are. We are going to consider in detail the GNSS constellations geometrical effects and how the quality of the orbit and clock products can affect the accuracy of the provided positioning solution. In addition to that, we are going to anayse the feasibility of providing the users with a dedicated correction built at server level in order to palliate the mentioned effects and we have been able to take one more step in the definition of a reliability bound for PPP. We are working in laying down the foundations for an upper-level reliability concept for PPP, closely linked to the final user perspective. We aim at achieving the challenging task of enabling a wide range of GNSS uses, those involving high positioning accuracy, as well as those in which a certain reliability bound is required.

Designing location and mobility aware solutions for message dissemination in vehicular ad-hoc networks

Vehicular Ad-hoc Network (VANET) is one of the potential solutions for providing low cost and best efforts connectivity platforms which can coexist with cellular and WiFi technologies. Due to high mobility of nodes and short lifetime of links, server-to-client and server-to-server communications become challenging. Effective context-aware broadcasting of information to the destination areas is also a challenge in VANET’s. It is usually assumed that the information about these areas is known a priori, either by a centralized source of information or by the entire set of vehicles. However, in reality, this information may not be available on demand. Message dissemination using partially known location information can reduce the overall throughput of the network. We propose to enhance the performance of server selection in a heterogeneous VANET by taking link reliability into consideration in the server selection mechanism.Thereby, extra client-to-server hand-offs are avoided and the need of serverto-server synchronization is reduced. We also propose an adaptive broadcasting scheme based on distributed reinforcement learning. In this scheme, vehicles collaboratively tune the rate of their message broadcasts based on the network dynamics without any initial knowl-
El papel de la cooperación técnica internacional en el proceso de modernización del Estado y de la gestión pública

I. Introducción La cooperación técnica tanto bilateral como multilateral es un fenómeno que aparece al término de la Segunda Guerra Mundial. Aumentar la eficiencia y eficacia del aparato del Estado fue y es una genuina preocupación de los países en desarrollo. Por una parte, el Estado jugó, hasta la primera mitad de la década de los 70 (Drucker, 1990: 8) un rol clave en el desarrollo económico social tanto en los países en vías de desarrollo como en los países desarrollados. Por otra parte, los países en vías de desarrollo necesitaban cooperación técnica para reformar el Estado, con el fin de poder cumplir con sus nuevas responsabilidades. Esta necesidad se hizo sentir, especialmente en las antiguas colonias francófonas y anglófonas de Africa y Asia.

In practical applications, graphic design is the product of the designer of creative thinking, the designer use of visual elements, such as symbols, images and text will own imagination materialized, and apply to all of life everything related to the visual environment of a kind of art. Under this theoretical basis, this paper integrates the new ideas of the interaction design and psychological guidance to propose the new idea that is innovative.
Evaluaciones subnacionales de la cobertura de las estadísticas vitales. Estudios recientes en América Latina

El logro de una buena cobertura de las estadísticas vitales (especialmente de los nacimientos y las defunciones), aún constituye un desafío muy importante en los países de América Latina. De ello depende el estudio de numerosas temáticas relacionadas con la salud de la población, como la situación y evolución de la natalidad, la fecundidad y la mortalidad. Al hacer un seguimiento de los avances en este aspecto, desde la demografía se ha notado que las técnicas de estimación más corrientes no funcionan adecuadamente al ser utilizadas en unidades geográficas o político-administrativas subnacionales. Para enfrentar el inconveniente, se están aplicando procedimientos poco frecuentes de estimación o incluso, desarrollando otras técnicas que permiten avanzar en el estudio de la cobertura de nacimientos y defunciones en diferentes niveles geográficos. En este trabajo se propone una revisión bibliográfica sobre las evaluaciones realizadas en América Latina desde el año 2000. Se recorta el análisis a estudios promovidos en el ámbito de los institutos nacionales de estadística y de los ministerios de salud, y considerando procedimientos principalmente de tipo directo.
Human aggressiveness and reactions towards uncertain decisions

Article history: Received 1 January 2019 Received in revised form 6 May 2019 Accepted 29 May 2019 Big data is a term that defines data sets are so large or complex that traditional data processing applications are inadequate. Data comes with different formats such as Multilanguage, structured, unstructured and emails. Challenges dealing with a huge amount of data includes analysis, search, sharing, transfer, and visualization. Not all the data collected contains useful information, so there's a need to refine this data in order to filter out the useful information. Tweets posted on Twitter are expressed as opinions. These opinions can be used for different purposes such as to take public views on uncertain decisions. These decisions have a direct impact on the user’s life such as violations and aggressiveness are common causes. For this purpose, we have collected opinions on some popular decision taken in the past decade from Twitter. We have divided the tweet text into two classes; Anger (negative) and positive. We have proposed a prediction model to predict public opinions towards such decisions. We used Support Vector Machine (SVM), Naïve Bayes (NB) and Logistic Regression (LR) classifier for a text classification task. Furthermore, we have also compared SVM results with NB, LR. The research will help us to predict early behaviors and reactions of people before the big consequences of such decisions. Moreover, the results highlight the feasibility of using social media to predict public opinions.
School Leaders’ Contribution to Social Justice: A Review

Purpose: The purpose of this review is to examine what is known as well as what we still seek to know in terms of principals’ potential contribution to social justice in their schools. Design/methodology/approach: This review provides an evaluative report of the current knowledge in the literature related to the influence of principals on social justice at the school building level. Findings: The current review reveals that there is solid evidence of the significant impact of school leaders on student learning. This impact constitutes the conceptual basis for social justice school leadership, where school leaders ascertain that all students are provided equal opportunities for quality education. However, the available knowledge regarding the optimal way to prepare social justice school leaders is still limited. Research implications: In as much as recent literature does not provide satisfactory answers to the question of how to train social justice school leaders, workable approaches to developing leaders who are effective in achieving social justice, equity, and excellence should be explored. Originality/value: In today’s Western school systems, non-White, LGBT, poor, or differently-abled students often lag behind their peers in academic achievement and acquisition of higher education while leading in school dropout rates. The review seeks to understand how school principals can bring about a real change in this undesirable situation, creating a social justice educational system.
Does physician engagement affect satisfaction of patients or resident physicians?

Purpose: This study examined whether change in physician engagement affected outpatient or resident physician satisfaction using common US measures. Methods: Surveys were administered by Advisory Board Survey Solutions for staff physician engagement, Press Ganey for Clinician and Group Consumer Assessment of Healthcare Providers and Systems (CGCAHPS) for outpatient satisfaction, and Accreditation Council for Graduate Medical Education (ACGME) for the ACGME Resident/Fellow Survey. Survey sample sizes were 685, 697, and 763 for physician engagement and 621, 625, and 618 for resident satisfaction in 2014–2016, respectively; only respondents were available for CGCAHPS (24,302, 34,328, and 43,100 for 2014–2016, respectively). Two groups were analyzed across 3 years: (1) percentage of “engaged” staff physicians versus percentage of outpatient top box scores for physician communication, and (2) percentage of “engaged” staff physicians versus percentage of residents “positive” on program evaluation. For resident evaluation of faculty, the number of programs that met/exceeded ACGME national compliance scores were compared. Univariate chi-squared tests compared data between 2014, 2015, and 2016. Results: For 2014–2016, “engaged” physicians increased from 34% (169/497) to 44% (227/515) to 48% (260/542) (P<0.001) whereas CGCAHPS top box scores for physician communication remained unchanged at 90.9% (22,091/24,302), 90.8% (31,088/34,328), and 90.9% (39,178/43,100) (P=0.869). For the second group, “engaged” physicians increased from 33% (204/617) to 46% (318/692) to 50% (351/701) (P<0.001) and residents “positive” on program evaluation increased from 86% (534/618) in 2014 to 89% (556/624) in 2015 and 89% (550/615) in 2016 (P=0.174). The number of specialties that met/exceeded national compliance for all five faculty evaluation items grew from 44% (11/25) in 2014 to 68% (17/25) in 2015 and 64% (16/25) in 2016 (P=0.182). Conclusion: For our medical group, improvement in physician engagement across time did not coincide with meaningful change in the outpatient experience with physician communication or resident satisfaction with program and faculty.
From Urban Sprawl to Compact City

Future urban growth strategies, at the regional, district and community levels, represent a decisive break from traditional predict and provide patterns of development. Plans for Auckland's urban future follow a theoretical debate over the virtues of urban sprawl and compact city types of development which has dominated urban planning literature over the past 15 years, as overall Auckland's strategies look to move away from sprawl as the basis for urban growth and focus more on intensification. However, as is outlined in the literature, there are many critiques of the compact city thesis, and those critiques can be readily applied to Auckland, especially with regards to feasibility and acceptability problems that have already plagued the implementation of intensification, as higher-density urban living contradicts with what most New Zealanders perceive to be an ideal lifestyle.
An Area-Efficient Carry Select Adder Design by Sharing the Common Boolean Logic Term

 Abstract—In this paper, we proposed an area-efficient carry select adder by sharing the common Boolean logic term. After logic simplification and sharing partial circuit, we only need one XOR gate and one inverter gate in each summation operation as well as one AND gate and one inverter gate in each carry-out operation. Through the multiplexer, we can select the correct output result according to the logic state of carry-in signal. In this way, the transistor count in a 32-bit carry select adder can be greatly reduced from 1947 to 960. Moreover, the power consumption can be reduced from 1.26mw to 0.37mw as well as power delay product reduced from 2.14mw*ns to 1.28mw*ns.
Dynamic scheduling algorithms for distributed soft real-time systems

This dissertation is a study of dynamic scheduling algorithms for distributed soft real-time systems with periodic workloads. Soft real-time systems permit deadline misses with the performance goal of minimizing the deadline miss ratio, the percentage of jobs missing their deadlines, and meeting the global priority requirement. In a distributed system with non-periodic workloads, dynamic assignment of tasks to processors can significantly improve system performance. However, job transfers and negotiations between processors exact a cost from the system, limiting performance improvement. Therefore, these algorithms must meet the real-time goals while minimizing the scheduling overhead. In order to minimize the global deadline miss ratio, an algorithm must employ a negotiation protocol to coordinate schedulers. We devise a triage protocol that attempts to transfer a job when the job cannot meet its deadline locally but can meet it at a remote processor. Based on this protocol, three initiation approaches are compared. The receiver-initiated approach is found to be most robust, whereas the sender-initiated approach may cause thrashing when the system load is high. Global priority scheduling attempts to ensure that the N jobs being served at any moment in the N -processor system are those having the highest priorities. If a job that is waiting has higher priority than the one that is running at a remote processor, the waiting job should be transferred to receive immediate service. The tradeoffs between reducing overhead and relaxing the global priority requirement are explored by comparing four algorithms, each exhibiting a different degree of compromise. For jobs consisting of a group of cooperating tasks, a global priority scheduling algorithm should take job structure into account. We devise algorithms that give compatible priority service to tasks belonging to a single job, so that cooperating tasks may progress at the same rate, avoiding excessive blocking due to synchronization. Under the assumption that there are two priority levels, our algorithms ensure that tasks are assigned to processors with the lowest priority loads. In total, we present six placement algorithms, evaluated under a workload consisting of jobs having a pipeline structure.
