By the early s computer manufacturers had begun to use semiconductor technology in commercial products, and both conventional batch-processing and time-sharing systems were in place in many large, technologically advanced companies. Host-to-host interactions were envisioned, along with access to specialized resources such as supercomputers and mass storage systems and interactive access by remote users to the computational powers of time-sharing systems located elsewhere. It connected time-sharing computers at government-supported research sites, principally universities in the United States , and it soon became a critical piece of infrastructure for the computer science research community in the United States. Tools and applications—such as the simple mail transfer protocol SMTP, commonly referred to as e-mail , for sending short messages, and the file transfer protocol FTP , for longer transmissions—quickly emerged. In order to achieve cost-effective interactive communications between computers, which typically communicate in short bursts of data, ARPANET employed the new technology of packet switching. Packet switching takes large messages or chunks of computer data and breaks them into smaller, manageable pieces known as packets that can travel independently over any available circuit to the target destination, where the pieces are reassembled. Thus, unlike traditional voice communications, packet switching does not require a single dedicated circuit between each pair of users. Commercial packet networks were introduced in the s, but these were designed principally to provide efficient access to remote computers by dedicated terminals. In the United States, Telenet and Tymnet were two such packet networks. Neither supported host-to-host communications; in the s this was still the province of the research networks, and it would remain so for many years.

After consulting several physiatrists and design psychologists not really , we present to you various building styles and their associated personalities. Sharp Edges Courtesy of Architectural Society of China If your building designs always turn out to be spiky, you probably look like this: Courtesy of Slikhaar TV Just a joke. You know it gets deeper than that. You are a person who can feel the energies in spaces around you, and you really enjoy these experiences. Meaning, you are highly sensitive to your surroundings and you always aim to create spaces that stimulate different emotions in people.

On its way there, this stormwater degraded the rivers and streams it flowed through and caused flooding in areas where hard surfaces terminally halt its infiltration. To deal with this regional calamity, the Great Lakes Commission and Lawrence Technological University have launched a new initiative to disseminate technology and techniques that can mitigate untreated stormwater pollution, the Great Lakes Stormwater Technology Transfer Collaborative.

Pebbles says there are three primary types of solutions the collaborative wants to better define in the marketplace: Regulatory requirements and building codes, such as parking ratio requirements, significantly affect the amounts of impermeable surface. Unlike drinking water pollution or direct sewage infiltration, untreated stormwater from paved surfaces is a threat not easily defined or isolated.

In doing so, workshops contaminate workers and the environment with toxic heavy metals like lead, beryllium and cadmium, while also releasing hydrocarbon ashes into the air, water and soil, the report said. For first-time visitors to Guiyu, the air leaves a burning sensation in the eyes and nostrils. Toxic tech Studies by the Shantou University Medical College revealed that many children tested in Guiyu had higher than average levels of lead in their blood, which can stunt the development of the brain and central nervous system.

Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of was discovered (along with krypton and xenon) in as one of the three residual rare inert elements remaining in dry air, after nitrogen, oxygen, argon and carbon dioxide were removed.
In the first post we talked about our motivation and some design decisions we considered when building the product, including an alternate version of Line that we decided not to build. We also talked a bit about the initial implementation of our matchmaking algorithm and the main constraints we put in place — pickup and detour time. This system was built fast and we quickly started to see its limitations.
In the second post , we talked about how we improved the Line experience by addressing issues such as backtracking and predicting rush hour traffic. We also talked about Triple Matching — the ability to match up to four passengers — and the changes we made, like Longitudinal Sorting, to build an efficient system that could handle the exponential increase in comparisons needed for this feature.
Many of these features have unlocked massive cost savings for our passengers, as ultimately the more efficient our system is, the greater the discount we can provide. Our greedy algorithm was built to find a match, and we made the first match that came along. As Line grew to become the majority of Lyft rides in San Francisco , we could no longer just pick the first match we found as that was leaving significant efficiency on the table.
We instead had to find the best possible match. This included considering all riders in our system in addition to predicting future demand.
Contact Architecture Eventhough I studied cinema and screenwriting, over the past years I have been working mostly in the field of architecture. This program connected Dutch architects to foreigner architects and foreigner project-developers to work on new daring, experimental architecture based on common ideas. The program focused on China, India and Brazil, mostly on the subject of social housing. This involved making a well-considered choice based on the capacities of these architecture firms as well as their experience with designing social housing and with operating in China.
The ten architects investigated the assignment as a team and devised a masterplan, in which the identities would remain intact.

Abstract Abstract — A distributed system is one in which components located at networked computers communicate and coordinate their actions only by passing messages. The research areas of multi-agent systems and distributed systems coincide, and form the research area of distributed agent computing. The study of multi-agent systems MAS focuses on systems in which many intelligent agents interact with each other.
In many situations, agents have to locate resources involving some kind of matchmaking. In this paper, we will give an overview of different approaches of matchmaking processes. We are interested in large-scale networks where certain nodes, called consumers, have to locate available resources and other nodes, called producers, are looking for tasks to execute. For matchmaking to occur, some issues must be considered, such as how to enable agents to decompose their tasks and goals, how to enable agents to communicate and how to enable agents to represent and reason about the actions, plans, and knowledge of other agents in order to interact with them.
Criteria such as the maximum number of matched tasks and resources, task allocation efficiency, resource usage efficiency and matching time must be considered. The choice of the matchmaking architecture will evidently impact important aspects such as task allocation, load balancing and routing as well as interaction between agents. In this paper we provide an overview of existing approaches such as centralized matchmaking and peer-to-peer communications and propose a framework that compares the different approaches in terms of performance, efficiency, communication cost and task complexity.
