Abstract

In this paper, we will survey and classify researching advanced routing algorithms that take advantages of MPLS (multiprotocol label switch) network to extent routing algorithms, supporting QoS (quality of service) services and traffic engineering and load balancing. We also consider some recent projects that are researching and working with advanced routing algorithms. This paper include 6 parts. Part 1 presents introduction. Part 2 presents QoS based routing, Classification of QoS routing. Part 3 presents traffic based routing based on information of current network such as: minimum interference routing algorithm (MIRA), dynamic online routing algorithm (DORA) and based on profile information such as: profile based routing (PBR). Part 4 presents employing advanced routing algorithms part 5 presents load balancing. And last, simulation with the combination of essential packages, we build simulation environments for MPLS based on ns2, setup some advanced routing algorithms, and evaluate them with old routing protocols.

110. Zombie Survival Optimization: A swarm intelligence algorithm inspired by zombie foraging.

Author

Nguyen, Hoang Thanh and Bhanu, Bir

Abstract

Search optimization algorithms have the challenge of balancing between exploration of the search space (e.g., map locations, image pixels) and exploitation of learned information (e.g., prior knowledge, regions of high fitness). To address this challenge, we present a very basic framework which we call Zombie Survival Optimization (ZSO), a novel swarm intelligence approach modeled after the foraging behavior of zombies. Zombies (exploration agents) search in a space where the underlying fitness is modeled as a hypothetical airborne antidote which cures a zombie's aliments and turns them back into humans (who attempt to survive by exploiting the search space). Such an optimization algorithm is useful for search, such as searching an image for a pedestrian. Experiments on the CAVIAR dataset suggest improved efficiency over Particle Swarm Optimization (PSO) and Bacterial Foraging Optimization (BFO). A C++ implementation is available.

Abstract

National surveys often report nursing home deficiencies related to the preservation of residents' dignity and respectful care. Many nurse aides (NAs), who provide the majority of personal care, are unprepared to engage in empathic and meaningful relationships with residents. This article reports the findings of a pilot mixed method study comparing two interventions, Story Sharing (StS) and Communication Skills, on NA levels of mutuality, empathy, job attitude, and self-efficacy and resident levels of empathy and perceived caring behaviors. A quasi-experimental/interpretive phenomenological design was used. Total Mutuality and subscale (Shared Values, Affective Closeness, Shared Pleasurable Activities, Reciprocity) scores were significantly higher in the StS NA groups only, as were postintervention Empathy scores. Other trends are reported as well. StS is one approach toward helping NH staff and residents understand, respect, and connect with one another., (Copyright 2010, SLACK Incorporated.)
