Non-linear mechanical behavior of polydimethylsiloxane (PDMS): application to the manufacture of microfluidic devices
(2004-01)Soft-lithography is a low-cost and convenient microfabrication technique that is becoming increasingly popular in the manufacture of microfluidic devices. A typical elastomer used in soft-lithography is polydimethylsiloxane ... -
Non-linear mechanical behavior of the elastomer polydimethylsiloxane (PDMS) used in the manufacture of microfluidic devices
(2005-01)Polydimethylsiloxane (PDMS) is the elastomer of choice to create a variety of microfluidic devices by soft lithography techniques (eg., [1], [2], [3], [4]). Accurate and reliable design, manufacture, and operation of ... -
Numerical Simulation of Electroosmotic Flow with Step Change in Zeta Potential
(2005-01)Electroosmotic flow is a convenient mechanism for transporting polar fluid in a microfluidic device. The flow is generated through the application of an external electric field that acts on the free charges that exists in ... -
On Dual Actuation in Atomic Force Microscopes
(2004-01)In this paper, the problem of dual actuation in the atomic force microscope (AFM) is analyzed. The use of two actuators to balance the trade-off between bandwidth, range, and precision has been recently extended to ... -
Optimal Capacity Adjustments for Supply Chain Control
(2003-01)Decisions on capacity are often treated separately from those of production and inventory. In most situations, capacity issues are longer-term, so capacity-related decisions are considered strategic and thus not part of ... -
Optimal Methodology for Synchronized Scheduling of Parallel Station Assembly with Air Transportation
(2005-01)We present an optimal methodology for synchronized scheduling of production assembly with air transportation to achieve accurate delivery with minimized cost in consumer electronics supply chain (CESC). This problem was ... -
Optimizing Safety Stock Placement in General Network Supply Chains
(2004-01)In the paper, we minimize the holding cost of the safety stock held in a supply chain modeled as a general network. By our assumption, the demand is bounded by a concave function. This fact allows us to formulate the problem ... -
Optimizing Strategic Safety Stock Placement in Two-Layer Supply Chains
(2003-01)In this paper, we minimize the holding cost of the safety stock in the supply chain subject to linear constraints on the service times between the nodes of the network. In the problem, the objective function is concave as ... -
Optimizing the Dynamic Distribution of Data-stream for High Speed Communications
(2005-01)The performances of high-speed network communications frequently rest with the distribution of data-stream. In this paper, a dynamic data-stream balancing architecture based on link information is introduced and discussed ... -
Particle Migration of Quasi-Steady Flow in Concentrated Suspension for Powder Injection Molding
(2002-01)A hybrid FEM/FDM algorithm for particle migration of quasi-steady flow in concentrated suspension materials is proposed in this study. This hybrid FEM/FDM algorithm in which the planar variables, such as pressure field, ... -
Patterns of Product Development Interactions
(2002-01)Development of complex products and large systems is a highly interactive social process involving hundreds of people designing thousands of interrelated components and making millions of coupled decisions. Nevertheless, ... -
Performance of a Serial-Batch Processor System with Incompatible Job Families under Simple Control Policies
(2006-01)A typical example of a batch processor is the diffusion furnace used in wafer fabrication facilities (otherwise known as wafer fabs). In diffusion, silicon wafers are placed inside the furnace, and dopant is flown through ... -
Performance-Driven Microfabrication-Oriented Methodology for MEMS Conceptual Design with Application in Microfluidic Device Design
(2005-01)Performance and manufacturability are two important issues that must be taken into account during MEMS design. Existing MEMS design models or systems follow a process-driven design paradigm, that is, design starts from the ... -
Pharmaceutical Properties of Nanoparticulate Formulation Composed of TPGS and PLGA for Controlled Delivery of Anticancer Drug
(2004-01)A suitable management of the pharmaceutical property is needed and helpful to design a desired nanoparticulate delivery system, which includes the carrier nature, particle size and size distribution, morphology, surfactant ... -
Planning and Scheduling Decisions in Supply Chains with Multiple Supply Modes: An Integrated Approach
(2005-01)We address the problem of jointly determining shipment planning and scheduling decisions with the presence of multiple shipment modes. We consider long lead time, less expensive sea shipment mode, and short lead time but ... -
Planning Design Iterations
(2002-01)Companies developing new products have a wide variety of product development (PD) processes from which to choose. Each process offers a different method of iteration to manage risk. Companies must therefore consider the ... -
