The static balancing of spherical three-degree-of-freedom (DoF) parallel mechanisms and manipulators is addressed in this paper. Static balancing is defined here as the set of conditions on mechanism dimensional and inertial parameters which, when satisfied, ensure that the weight of the links does not produce any torque (or force) at the actuators for any configuration of the mechanism, under ...

There is an increasing demand to simulate and optimize the performance profit of comminution circuits, especially in low-grade ore processing, as case with critical metals minerals. Recent research has shown that optimization result greatly influenced by quality aspects products, such cost, profit, capacity. This paper presents a novel approach performing multi-objective technical economic anal...

The Design, Optimization, and Performance of an Adaptive Middlware Load Balancing Service by Ossama Othman Master of Science in Electrical and Computer Engineering University of California, Irvine Professor Douglas C. Schmidt, Chair Distributed object computing (DOC) middleware is increasingly used as the infrastructure for applications with stringent quality of service (QoS) requirements, incl...

In MIPv6 network most of the HA load balancing deals with Dynamic Home Agent Address Discovery (DHAAD). Load balancing of multiple Home Agents (HAs) has not been standardized. Our contribution in this paper, Dynamic HA selection with Load Balancing mechanism (DHSLB) mechanism is categorized into two phases. First, we introduce HA selection based on preference value and load. Second, we analyze ...

In this paper, we present a game theoretic framework for obtaining a user-optimal load balancing scheme in heterogeneous distributed systems. We formulate the static load balancing problem in heterogeneous distributed systems as a noncooperative game among users. For the proposed noncooperative load balancing game, we present the structure of the Nash equilibrium. Based on this structure we der...

Load balancing is a technique in which workload is distributed across multiple computers or other resources to get optimal resource utilization, minimum time delay, maximize throughput and avoid overload. Mainly in operation of parallel and distributed computing systems, load balancing problem arises. Load balancing scheme can be characterized as: static and dynamic load balancing. This paper r...

Distributed processing can be used for solving large computation intensive problems. A distributed system may include parallel supercomputers, networked workstations and PCs. This paper discusses load balancing of a parallel job in a distributed computation environment. The information necessary for load balancing is studied. The software tools that automatically collect the information and per...

As IPv6 deployment grows, it is important to develop new measurement techniques that allow us to study the IPv6 Internet. We implement an IPv6 version of the Multipath Detection Algorithm and use it from 12 geographically-distributed vantage points on two different platforms to characterize IPv6 routers that perform load balancing. Overall, we find that 74% of IPv6 routes traverse at least one ...

December 1, 2009, marks the tenth anniversary of the Institute of Medicine report on medical errors, To Err Is Human, which arguably launched the modern patient-safety movement. Over the past decade, a variety of pressures (such as more robust accreditation standards and increasing error-reporting requirements) have created a stronger business case for hospitals to focus on patient safety. Rela...

In some schools and universities, students from the same grade must sometimes be divided into several teams within a classroom in such a way that each team provides a good representation of the classroom population. Therefore a first problem to solve is to choose student attributes (criteria) to include into the process of designing the teams and to determine their relative importance for the s...
