This thesis examines two different approaches to active buckling control of a compressively-loaded structural element. The phenomenon of buckling is the single most important factor limiting the load-bearing strength of a structure. Active control of buckling allows us to increase the load-bearing capabilities of compressive members, leading to structures that are both stronger and lighter than...

In this article is proposed a Centralized Sliding Mode Control (CSMC) applied to a UPFC device for controlling power flow and enhancing power system stability. First, we establish a state-space dynamic model of UPFC based on Kirchhoff’s equations and (d-q) transformation. This model includes the two voltage source inverters and the DC bus voltage link. Furthermore, in order to cancel the effect...

Traditional approaches to network supercomputing employ a master process and a large number of potentially undependable worker processes that must perform a collection of tasks on behalf of the master. In such a centralized scheme, the master process is a performance bottleneck and a single point of failure. This work develops an original approach that eliminates the master and instead uses a d...

Version control systems are critical for coordinating work in large software engineering teams. Recently, distributed version control (DVC) systems have become popular, as they have many advantages over their centralized (CVC) counterparts. DVC allows for more frequent commits, and simplifies branching and merging. These features encourage developers to make smaller, finergrained commits that d...

We consider a manufacturer, served by a single supplier, who has to quote due dates to arriving customers in a maketo-order production environment. The manufacturer is penalized for long lead times and for missing due dates. To meet due dates, the manufacturer has to obtain components from a supplier. We model this manufacturer and supplier as a two-machine flow shop, consider several variation...

In this paper, Model Predictive Control of Quadruple tank process for centralized and decentralized method is proposed. Multi Input Multi Output (MIMO) processes are inherently more complex than Single Input Single Output (SISO) process because process interactions occur between controlled and manipulated variables. This problem can be solved using centralized and decentralized controllers. Mod...

Current L0 or loop buffer organizations for VLIW processors are essentially centralized, as a consequence they are energy inefficient and their scalability is limited. In this context, we propose a clustered loop buffer organization, where the loop buffers are partitioned and functional units are logically grouped to form instruction clusters, along with two schemes for the buffer control which...

The need for advanced network control functions such as traffic Engineering, service insertion and service chaining, multi-tenancy, and tenant isolation are increasingly growing as Network Virtualization becomes the dominant trend in the Data Center and Cloud. The rise of such new requirements has exacerbated the inadequacy and lack of flexibility of today’s network management and control mecha...

This paper gives a new solution to the output feedback H2 model matching problem for a large class of delayed information sharing patterns. Existing methods for such problems typically reduce the decentralized problem to a centralized problem of higher state dimension. In contrast, the controller given in this paper is constructed from the solutions to the centralized control and estimation Ric...
