Self Compacting Concrete (SCC) is defined as a category of High Performance Concrete that has excellent deformability in the fresh state and high resistance to segregation, and can be placed and compacted under its self weight without applying vibration. SCC was first developed in Japan in mid 1980. Since then, it has found applications in reinforced concrete sections containing congested reinforcements. Poor quality of vibration of concrete, in congested locations, has often been a shortcoming of traditional concrete. In such situations, SCC, ....etc

These notes provide an introduction to unsupervised neural networks, in particular Kohonen self-organizing maps; together with some fundamental background material on statistical pattern recognition.

One question which seems to puzzle many of those who encounter unsupervised learning for the first time is how can anything useful be achieved when input information is simply poured into a black box with no provision of any rules as to how this information should be stored, or examples of the various groups into which this informa ....etc

As you can guess, hardwired computer systems are much faster than general-purpose ones because they are designed to do a single task. But when they fail, they need to be totally reconfigured. This can be just a costly problem in a lab on Earth, but it can be vital in space. This is why a University of Arizona (UA) team is working with NASA to design self-healing computer systems for spacecraft. The UA engineers are working on hybrid hardware/software systems using Field Programmable Gate Arrays (FPGAs) to develop these reconfigurable processing ....etc

Concrete is the most used construction material in the world and if correctly composed, it can be vary durable and thus save considerable society resources in maintenances cost. Self-compacting concrete is one of the subjects of concrete technology and the various investigations have been carried out and hence the concrete has been used in practical structures. In this paper, a brief introduction to self-compacting concrete (SCC) is given. And also the definition and motive for development of SCC have been discussed. The SCC has some advantages ....etc

Cascode amplifier
An amplifier stage consisting of a common-emitter transistor cascaded with a common-base transistor (see illustration). The common-emitter-common-base (CE-CB) transistor pair constitutes a multiple active device which essentially corresponds to a common-emitter stage with improved high-frequency performance. In monolithic integrated-circuit design the use of such active compound devices is much more economical than in discrete designs. A similar compound device is the common-collector-common-emitter ....etc

Abstract
Swarm-bots consist of a collection of mobile robots able to self-assemble and to self-organize so to
solve problems that could not be solved by a single robot. They combines the power of swarm
intelligence and the flexibility of self-reconfiguration as aggregate swarm-bots have the ability to
dynamically change their structure to match environmental variability.
SWARM-BOTS, a project funded by the Future and Emerging Technologies program of the
European Community (project IST-2000-31010), focuses on the design and the imp ....etc

computing components anticipate computer system needs and resolve problems with minimal human intervention.

Self managing computing systems have the ability to manage themselves and dynamically adapt to change in accordance with business policies and objectives. Self-managing systems can perform management activities based on situations they observe or sense in the IT environment. Rather than IT professionals initiating management activities, the system observes something about itself and acts accordingly. This allows the IT professional to ....etc

The high-tech industry has spent decades creating computer systems with ever mounting degrees of complexity to solve a wide variety of business problems. Ironically, complexity itself has become part of the problem. As networks and distributed systems grow and change, they can become increasingly hampered by system deployment failures, hardware and software issues, not to mention human error. Such scenarios in turn require further human intervention to enhance the performance and capacity of IT components. This drives up the overa ....etc

WHY CASCODE BETTER?


IT IS A SINGLE STAGE AMPLIFIER WITH GAIN ENHANCEMENT.
WHILE A CASCADE IS TWO STAGE AMPLIFIER.
IT HAS SINGLE NODE IS AT HIGHER IMPEDENCE,WHERE GAIN IS REALIZED.
IN THIS GBW IS DETERMINED BY INPUT TRANSCONDUCTANCE AND LOAD CAPACITANCE.
