Pindar Set Limited the UK company that originates the Yellow Pages for British Telecom munications plc has developed a business strategy based upon a generic knowledge based batch layout software suite for use by publishers internationally Pindar s clients pub lishers such as BT increasingly insist on faster and more exible responses to requests for changes in the way their books are laid out a...

outdoor experiments on a once-through single glazed solar air heater with perforated metal absorber plate were conducted to determine the practical effect of absorber plate porosity as well as suction air flow rate on the collector thermal efficiency and its total pressure drop. three aluminum absorber plates were made perforated by drilling circular holes with different diameter/pitch ratios i...

Graph drawing algorithms have important practical applications, e. g. layer-based algorithms for data flow diagram layout in embedded software design and planarization-based algorithms to layout UML diagrams in software engineering. Most current drawing methods focus on the optimization of aesthetic criteria such as the number of edge crossings and bends. The aspects of compactness and aspect r...

The paper presents a model of designing of machine layout in flexible manufacturing system (FMS). Evolutionary computation, particularly genetic algorithms (GAs) proved to be successful in search of optimal solution for this type of problems. To achieve high productivity in a flexible manufacturing system (FMS), an efficient layout arrangement and material flow path design are important due to ...

It is often difficult to visualize large networks effectively. In BioReact, we filter large systems biology network data by querying to select partial network as the input for visualization. Each query is parameterized by a node name, the direction of graph search, and the scope of the search. We present two layouts of the same network to clearly show network topology: a force-directed layout e...

Despite 30 years of Electronic Design Automation, analog IC layouts are still handcrafted in a laborious fashion today due to the complex challenge of considering all relevant design constraints. This paper presents Self-organized Wiring and Arrangement of Responsive Modules (SWARM), a novel approach addressing the problem with a multi-agent system: autonomous layout modules interact with each ...

With new defenses against traditional control-flow attacks like stack buffer overflows, attackers are increasingly using more advanced mechanisms to take control of execution. One common such attack is vtable hijacking, in which the attacker exploits bugs in C++ programs to overwrite pointers to the virtual method tables (vtables) of objects. We present a novel defense against this attack. The ...

Semiconductor manufacturing is an important component of the U.S. manufacturing industry. Most of today’s fabrication facilities and those being designed for the near future use a bay layout configuration and an overhead monorail system for moving material between bays. These material handling systems are usually designed with a spine or perimeter type of configuration. This paper investigates ...

Developing a group of machine cells and their corresponding part families to minimize the inter-cell and intra-cell material flow is the basic objective of the designing of a cellular manufacturing system (CMS). Afterwards achieving a competent cell layout is essential in order to minimize the total inter-cell part travels, which is principally noteworthy. There are plentiful articles of CMS li...

In this paper we analyze and evaluate the effects of some pre-defined process parameters on the performance of a manufacturing system. These parameters include two different plant layout types, namely functional layout (FL) and cellular manufacturing layout (CL), as well as scheduling rule, machine downtimes, batch sizes, and transporter (interstage transporters) capacities. First we employ sim...
