A New Scalable and Cost-Effective Congestion Management Strategy for Lossless Multistage Interconnection Networks
2005
In this paper, we propose a new congestion management strategy for lossless multistage interconnection networks that scales as network size and/or link bandwidth increase. Instead of eliminating congestion, our strategy avoids performance degradation beyond the saturation point by eliminating the HOL blocking produced by congestion trees. This is achieved in a scalable manner by using separate queues for congested flows. These are dynamically allocated only when congestion arises, and deallocated when congestion subsides. Performance evaluation results show that our strategy responds to congestion immediately and completely eliminates the performance degradation produced by HOL blocking whi…
Congestion Avoidance Using DYnamic COdec MAnagement: A solution for ISP
2005
The large diffusion of VoIP is an essential key for the success of emerging Internet service providers. These ISPs conflict with the interests of historical and predominant network maintainers which often control the network infrastructure and telephone services. To win this competition, emerging ISPs have to adopt strategic QoS solutions which will capture the attention of network users and phone clients. This paper presents a solution which is able to obtain the same performance of a 64 Kbps channel reducing the costs for over-provisioning network bandwidth. DyCoMa is a mechanism studied for VoIP applications in network with a limited bandwidth for multimedia services. It works preventing…
Applying Dynamic Performance Management to Enterprises
2016
This chapter will illustrate two examples of DPM applied to enterprises. Cases will show how DPM can support a learning-oriented approach into the P&C processes of business organizations.
Phenotypic Flexibility in the Social Organization of Clethrionomys
1990
I review the flexibility of social organization and spacing behavior in Clethrionomys. This review is based on a 6-year comparative study and several experimental studies on cyclic populations of the bank vole, C. glareolus, in Central Finland. The social organization of Clethrionomys populations shows great flexibility during both the breeding and nonbreeding season, and is dependent on habitat patchiness, food availability, Predation, kinship, philopatry, and familiarity between individuals. The first three factors are most important in destabilizing a population, whereas the last three stabilize a population without exhausting its resources. Female territoriality can weaken in a producti…
The World Bank’s Early Reflections on Development: A Development Institution or a Bank?
2009
Until the late 1960s, the World Bank presented itself as an institution devoted to making sound and directly productive project loans. Yet, during its very early years, some discussions developed inside the Bank regarding the possibility of issuing different types of loans, namely (i) loans aimed at tackling social issues ("social loans"), and (ii) loans aimed at providing foreigncurrency to address disequilibria in the balance of payments ("impact loans"). This paper brings together historical analysis and theories of organization development to study the housing issue as a case in point. The analysis reveals that the Bank was unwilling to lend for housing programs not because these were n…
Director Compensation Incentives and Acquisition Outcomes
2018
The principal objective of this chapter is to investigate the relation between director compensation structure and shareholder interests in the context of acquisitions. Our evidence suggests that acquirer firms that compensate their directors with a higher proportion of incentive-based compensation have significantly higher stock returns around the announcement. An increase in director equity-based pay results in a lower probability of value-destroying acquisitions and a lower acquisition premium for targets. We further find that acquirers with higher equity-based pay exhibit greater improvements in stock price and operating performance following acquisitions.
Optimal Relays Deployment for 802.16j Networks
2012
In this paper, we consider optimal relay station deployment for the IEEE 802.16j networks. IEEE 802.16j is an emerging wireless broadband networking standard that integrates infrastructure base stations with multihop relay technology. The proposed relay deployment mechanism allows us to maximize network capacity for every user or to maximize total network capacity, and, therefore, to reach greater network capacity values while employing smaller number of relay stations. With the proposed approach, the necessary number of relays for a region can be found.
The pricing capability lifecycle of digital innovations
2021
The pricing capability provides a basis for firms’ competitive advantage. However, to date, the literature has not investigated how this capability forms, develops, and matures. In this study, we define the pricing capability as a dynamic capability consisting of three operational building blocks (tools and data, human and relational resources, and processes, routines, and mechanisms) as well as two dynamic capability building blocks (alertness and responsiveness, and value-based strategic thinking). Furthermore, we propose the pricing capability lifecycle of digital innovations that incorporates insights of the dynamic capabilities view (DCV). Based on a longitudinal multi-case study of fi…
A team fares well with a fair coach: Predictors of social loafing in interactive female sport teams
2014
The present research aimed to develop and test a theoretical model that links players' perceived justice of the coach to a more optimal motivational climate, which in turn increases players' team identification and cohesion, and results in lower levels of social loafing in female sport teams. Belgian elite female basketball, volleyball, and football players (study 1; N = 259; M(age) = 22.6) and Norwegian world-class female handball players (study 2; N = 110; M(age) = 22.8) completed questionnaires assessing players' perceived justice (distributive and procedural), motivational climate, team identification, team cohesion (task and social), and social loafing (perceived and self-reported). …
Predicting the Batteries' State of Health in Wireless Sensor Networks Applications
2018
[EN] The lifetime of wireless sensor networks deployments depends strongly on the nodes battery state of health (SoH). It is important to detect promptly those motes whose batteries are affected and degraded by ageing, environmental conditions, failures, etc. There are several parameters that can provide significant information of the battery SoH, such as the number of charge/discharge cycles, the internal resistance, voltage, drained current, temperature, etc. The combination of these parameters can be used to generate analytical models capable of predicting the battery SoH. The generation of these models needs a previous process to collect dense data traces with sampled values of the batt…
