Energy-Efficient Approximate Computation in Topaz

REA Auditado

We present Topaz, a new task-based language for computations that execute on approximate computing platforms that may occasionally produce arbitrarily inaccurate results. The Topaz implementation maps approximate tasks onto the approximate machine and integrates the approximate results into the main computation, deploying a novel outlier detection and reliable reexecution mechanism to prevent unacceptably inaccurate results from corrupting the overall computation.

A Coded Shared Atomic Memory Algorithm for Message Passing Architectures

REA Auditado

This paper considers the communication and storage costs of emulating atomic (linearizable) multi-writer multi-reader shared memory in distributed message-passing systems. The paper contains three main contributions: (1) We present a atomic shared-memory emulation algorithm that we call Coded Atomic Storage (CAS). This algorithm uses erasure coding methods. In a storage system with 'N' servers that is resilient to 'f' server failures, we show that the communication cost of CAS is N/(N-2f) . The storage cost of CAS is unbounded.

Knowledge Management: an Analysis From the Organizational Development

REA Auditado

This research develops a theoretical framework on the implications of the organizational characteristics on the knowledge management (KM). The organizational characteristics are handled in this work as constructs, as they are complex concepts. This paper is based on a theoretical research, considering original and classic articles on KM. From a broad theoretical-conceptual research, the paper presents as a result five organizational constructs that support the KM process: human resources, team work, organizational culture, organizational structure and development and absorption of knowledge.

Collaborative Innovation in Agrometeorology: Coordination Strategies to Develop a Monitoring IT System for Brazil

REA Auditado

This case-study article presents the results from a morphology analysis of a knowledge and information network, focusing on the coordination mechanisms employed to generate a convergent arrangement. Agritempo was the first information system to offer (in 2003) free access to a broad range of agrometeorological data comprising all the Brazilian territory, representing an important technological innovation to the agricultural sector. To study this phenomenon an analytical framework of the Techno-Economic Network (TEN) and concepts from the Innovation Sociology field was employed.

Assessing Centralized Governance in a Software Cluster

REA Auditado

Increasing attention has been paid to the creation of spatially concentrated environments (industrial agglomerations or clusters) that aim at fostering firm-level competitiveness. However, while much has been said about clusters in general, less attention has been paid to structural governance within these agglomerations. This paper discusses the economic dynamics of clusters in the presence of centralized formal body of governance regarding internal and external relationships.

Performance Evaluations of Technology Transfer Offices of Major US Research Universities

REA Auditado

By analyzing the highlights of the major activities reported by the technology transfer offices (TTOs) of twenty US major universities, the performances of TTO activities are quantitatively assessed and the associated scores are compared with each other. The key performance indicators, which govern the success of the university technology transfer, are specifically selected and examined. Two normalized metrics, overall performance metric (OPM) and patenting control ratio (PCR), which are the representing combined indicators for the TTO performance, are developed and demonstrated.

Procedural Priorities of the Pork Loin Supply Chain

REA Auditado

The pork meat production industry is facing new challenges as a consequence of consumers' expectations regarding the quality and safety of food products. For the present study, experts and consumers in Rio Grande do Sul State, Brazil were interviewed to identify the attributes of pork loin that need to be improved. Consumers have particular concerns about the juiciness, fibrousness, and portion size of the meat, the diversity of cuts and safety and animal welfare.

Characterization of the Relationship Between Firms and Universities and Innovation Performance: The Case of Colombian Firms

REA Auditado

Within the National Innovation System, universities play a key role as the main source of knowledge that supports national productivity and as a system that seeks to improve the competitiveness of firms competitiveness and to find answers concerning market needs in today's fast-changing and globalized economy. Innovation, as a source of competitiveness, is normally supported by a firm's technological capabilities: internal R & D, external collaborative agreements, and relationships with universities.

Strategic Implications of Water Usage: an Analysis in Brazilian Mining Industries

REA Auditado

This study aims at identifying the practices of water use management and the business performance in industries in the Brazilian mineral sector. To this end, a descriptive and quantitative study was developed, using the survey method, in industries associated with the Brazilian Mining Institute - IBRAM. The water use management practices were identified based in a model addressing the following aspects: water accounting, risk assessment, direct operations, supply chain, and stakeholders engagement.

R&D and Innovation Management in the Brazilian Electricity Sector: The Regulatory Constraint

REA Auditado

In 2000 it became mandatory to the Brazilian electricity companies to invest in research, development and innovation (RDI). These investments are performed by firms and regulated by the Brazilian Electricity Regulatory Agency (ANEEL). Since then companies have sought ways to cope with this obligation creating internal structures and managerial processes.
