In this paper we introduce the unsupervised machine-learning algorithm named Local Outlier Factor (LOF), for health risk assessment. In general the LOF algorithm is used with numerical attributes and the outcome of the algorithm is parting the patterns into normal and abnormal events. In this paper we introduce the extended LOF algorithm with three experimental contributions: (i) utilization of...

In this paper, we compare the effects of machine pooling and labor chaining by means of a simulation study. In this study, the independent variables are: (1) the level of machine pooling (no. of jobs that can be produced in more than one cell), (2) the level of labor chaining (no. of workers able to work in more than one cell), and (3) labor utilization/machine utilization. The dependent variab...

VMware ESX Server offers three choices for managing disk access in a virtual machine—VMware Virtual Machine File System (VMFS), virtual raw device mapping (RDM), and physical raw device mapping. It is very important to understand the I/O characteristics of these disk access management systems in order to choose the right access type for a particular application. Choosing the right disk access m...

Optimal resource utilization for executing tasks within the cloud is one of the biggest challenges. In executing the task over a cloud, the resource provisioner is responsible for providing the resources to create virtual machines. To utilize the resources optimally, the resource provisioner has to take care of the process of allocating resources to Virtual Machine Manager (VMM). In this paper,...

Hensel’s lemma, combined with repeated applications of Weierstrass preparation theorem, allows for the factorization polynomials multivariate power series coefficients. We present a complexity analysis this method and leverage those results to guide load-balancing parallel implementation concurrently update all factors. In particular, creates pipeline where terms degree k first factor are compu...

Cloud Computing offers indispensable infrastructure for storage and computing facilities for development of diversified services. The large utilization of resources leads to increased energy consumption that has imposed a limit on performance growth. Owing to high operational costs and carbon dioxide footprints, an efficient energy management technique needs to be developed and deployed that re...

In this paper, we present new techniques which further improve the static compilation-based instruction set architecture (ISA) simulation by the aggressive utilization of the host machine resources. Such utilization is achieved by defining a low-level code-generation interface specialized for ISA simulation, rather than the traditional approaches which use C as a code-generation interface. We a...

This paper proposes an integrated analyticd/simulation approach for designing an automated guided vehicle system (AGVS) which consists of AGVs, machines with input buffers and a dispatching station in a just-in-time (JIT) envkonment. The objective is to determine the number of AGVs, the input buffer capacities and locations of the machines that minimize a cost function under the constraint that...
