Material handling is a loose loop in most assembly plants. Jiist-in-time (JIT) is a management philosophy that strives to eliminate sources of manufacturing waste by producing the right part in the right place at the right time. We propose to apply JIT principles to material handling in assembly plants. Material Kanbans are introduced as an effective means to control and balance the physical ma...

level, the primary decisions for a remelter involve composing alloy batches by carefully selecting and mixing various amounts of scrap and primary materials. Sorting provides added flexibility as well as complexity to these decisions by affording the secondary processor the opportunity to upgrade the materials which they have at hand. With sorting, the set of operational decisions include what ...

Recently, the fabrication of CdSe nanoplatelets became an important research topic. Nanoplatelets are often described as having a similar electronic structure as two-dimensional quantum wells and are promoted as colloidal quantum wells with monolayer precision width. In this paper we show that nanoplatelets are not ideal quantum wells, but cover depending on the size: the strong confinement reg...

In most applications based on chemical vapor deposition (CVD) graphene, the transfer from the growth to the target substrate is a critical step for the final device performance. Manual procedures are time consuming and depend on handling skills, whereas existing automatic roll-to-roll methods work well for flexible substrates but tend to induce mechanical damage in rigid ones. A new system that...

In perceptual experiments, quantitative manipulation of acoustic features in speech material is often required. And obviously, it can be realized only with speech synthesis techniques. Some of the authors have conducted a series of perceptual experiments, through which they have felt necessity of a system to generate more natural speech. With these backgrounds, a speech stimuli generation syste...

Some grippers operate using Bernoulli Principle for generating a high-speed flow between the gripper plate and product surface thereby creating vacuum which lifted the product. Most of the robot grippers are not easily applicable due to the food products are often delicate, easily marked or bruised, adhesive and slippery. Feasibility observations are studied to demonstrate and obtain an overall...

In recent year, multi-layered semiconductor package is one of the most important technologies to enhance its performance. To bond between each layer of multi-chip package, die-bonding film is known as an effective material. We had developed a novel low-modulus die-bonding adhesive film. Properties of the films are widely changed by the ratio of epoxy resin and acrylic polymer contents. To satis...

In real-word manufacturing environments, finding the right job sequences and their associated schedules when resource, precedence, and timing constraints are imposed is a difficult task. For most practical problems classical scheduling easily leads to an exponential growth in the number of possible schedules. Moreover, a decision time period of hours or even minutes is too long. Good solutions ...

An Expert System for aid in material selection process is proposed, which in conjunction with TOPSIS(Technique for Order Preference by Similiarity to Ideal Situation) method[l] provides a very effective and efficient technique of material selection for a component. TOPSIS is a highly advanced optimization technique, which requires that user provides relative importance to different properties b...

This paper attempts to find out the best available alternative material handling system (MHS), an integral component of warehouse operations. Analytic Hierarchy Process (AHP), a flexible decision making tool for complex, multi-criteria problems and useful to provide management weightage, has been used in this study to develop performance model. The proposed algorithm, used to select the proper ...
