Summary
Market-driven agents (MDAs) offer efficient solutions for Grid resource negotiation. These agents achieve higher budget efficiencies and success rates in acquiring computational resources, even under high demand.
Area of Science:
- Computer Science
- Distributed Computing
- Artificial Intelligence
Background:
- Efficient resource management is crucial for computational grids.
- Negotiation between independent grid providers and consumers is complex.
- Existing resource allocation mechanisms face challenges in dynamic environments.
Purpose of the Study:
- To evaluate market-driven agents (MDAs) as a tool for Grid resource negotiation.
- To demonstrate the effectiveness of MDAs in a simulated Grid-commerce environment.
- To compare MDA performance against other e-negotiation agents.
Main Methods:
- Development of a heterogeneous testbed simulating a Grid computing environment.
- Implementation of market-driven agents (MDAs) with flexible concession strategies.
- Comparative performance analysis of MDAs against agents like Kasbah.
Main Results:
- MDAs achieved higher budget efficiencies across various market conditions.
- MDAs demonstrated superior success rates in acquiring Grid resources under high load.
- MDAs exhibited flexibility in adjusting negotiation terms based on market pressures.
Conclusions:
- Market-driven agents are effective tools for Grid resource negotiation.
- MDAs provide a robust solution for optimizing resource allocation in computational grids.
- The findings support the adoption of agent-based negotiation for Grid-commerce.

Global regulatory systems in bacteria enable rapid and coordinated responses to environmental changes by integrating sensory inputs with gene expression, ensuring efficient adaptation to fluctuating conditions. Key global regulatory mechanisms include regulons, two-component systems, sigma factors, and secondary messengers.Regulons and Global RegulatorsA regulon is a collection of genes and operons controlled by a common global regulator. These regulators enable bacteria to prioritize resource...
01:25Distribution Reliability and Automation
Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...
01:27Transformers in Distribution System
Transformers in distribution systems can be broadly categorized into distribution substation transformers and other distribution transformers. They are crucial for stepping down high transmission voltages to levels suitable for distribution and end-user applications.
Distribution substation transformers come in various ratings and typically use mineral oil for insulation and cooling. To prevent moisture and air from entering the oil, some transformers use an inert gas like nitrogen to fill the...

01:30Control of Power Flow
There are several methods to control power flow in power systems:
01:15G Protein-coupled Receptors
G Protein-Coupled Receptors or GPCRs are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to sensory stimuli such as light, odors, hormones, cytokines, or neurotransmitters.
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...

GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...
