Abstract Concrete mix design is the methodology for mixing binder, aggregate and water to achieve required physical, mechanical, thermal properties. In particular, physical properties depend on volume fraction of each element in concrete recipe. this study we considered cement mortar, complying with ASTM C105, as reference binder silica sand aggregate. The mortar was denser high conductivity co...

The Ovm framework is a set of tools and components for building language runtimes. We present the common intermediate representation of this framework and software design patterns used throughout Ovm. One of the main themes in this work has been to support experimentation with new linguistic constructs and implementation techniques. To this end, Ovm components were designed to be parametric wit...

The preformulation of insoluble drugs, sulfadiazine and aluminium hydroxyde, were studied in order to achieve a suspension with desirable requirements. The objective of the formulator is to avoid the irreversible aggregation called “caking”, and to obtain a suspension with an airy, large volume sediment easily redispersible and with suitable rheological properties. An experimental design useful...

Experimental design is a powerful approach to study the impact of potential variables affecting systems and provides spontaneous insight for continuous improvement possibilities. Most research in system design has focused on problems with a single characteristic or response. This paper is concerned with the application of a design method to problems with multiple characteristics. The study sequ...

This paper reports the results of the second phase of a research project to characterize and optimize the design of an advanced launch vehicle for human access to low earth orbit. The vehicle makes use of rocket-based combined-cycle (RBCC) propulsion — a concept combining operating modes of an ejector, ramjet, scramjet, and rocket in a single engine. This research builds on previous work focuse...

ingle-case research designs are a diverse and powerful set of procedures useful for demonstrating causal relations among clinical phenomena. Although such designs are flexible, efficient, and have been used to make key advances since the earliest days of psychological science, they are currently extremely underused by psychological scientists and clinicians. We review the historical and theoret...

SystemVerilog has been widely adopted as a language for hardware design and verification. At the same time, SystemVerilog is a very large and complex language which can be daunting to learn and use, and differences still remain between implementations. SystemVerilog adoption has been given a new impetus in recent years with the introduction of UVM, the Universal Verification Methodology for Sys...

this paper presents the findings of experimental investigations into the effects of cutting speed, feed rate, depth of cut and approach angle on the machinability of titanium (grade-5) alloy. also the comparison for the two different cutting materials inserts polycrystalline diamond (pcd) and cubic boron nitride (cbn) with similar tool geometry for similar machining parameters is also carried o...

for all industrial processes, modelling, optimisation and control are the keys to enhance productivity and ensure product quality. in the current study, the optimization of process parameters for improving the conversion of isoeugenol to vanillin by psychrobacter sp. csw4 was investigated by means of taguchi approach and box-behnken statistical design under resting cell conditions. taguchi desi...
