double emulsion solvent evaporation technique is one of the most attractive methods used to prepare micro and nanoparticles in pharmaceutical areas of interest, but because of the effects of many formulation factors on the size and release behavior of the fabricated particles, optimization of the formulation factors is needed. in this study various parameters including technical and composition...

Metaheuristic algorithms are preferred by the many researchers to reach the reliability based design optimization (RBDO) of truss structures. The cross-sectional area of the elements of a truss is considered as design variables for the size optimization under frequency constraints. The design of dome truss structures are optimized based on reliability by a popular metaheuristic optimization tec...

Some computable schemes for descent methods without line search are proposed. Convergence properties are presented. Numerical experiments concerning large scale unconstrained minimization problems are reported. Mathematical subject classification: 90C30, 65K05, 49M37.

The optimization of formulation is the next task to formulate an effective rapid dispersible tablet with ideal wetting, dispersion properties to achieve rapid release profile of finished product. In preliminary work, the initial formulation was established to enhance the solubility and rapid release of Tolfenamic acid, but the optimization of size of granules and quantity of disintegrants was n...

This thesis studies the problem of reducing code size produced by an optimizing compiler. We develop the Value State Dependence Graph (VSDG) as a powerful intermediate form. Nodes represent computation, and edges represent value (data) and state (control) dependencies between nodes. The edges specify a partial ordering of the nodes—sufficient ordering to maintain the I/O semantics of the source...

A transistor sizing algorithm for row-based layouts is presented under a improved area model. This algorithm uses convex programming to nd a minimal area circuit for a given delay speci cation. The new area model uses a concept of row heights as opposed to the conventional metric of sum of gate sizes. Results over a number of circuit indicate a signi cant reduction both in the minimum delay ach...

in the present study, fe3o4 super paramagnetic nanoparticles were synthesized via co-precipitation of fe3+ and fe2+ chloride salts in the presence of ammonia solution. the product was characterized by fourier transform infrared spectroscopy (ft-ir), transmission electron microscopy (tem), and zeta–potential particle size distributing methods. the synthetic procedure of nano iron oxides were opt...

This paper analyzes and discusses the problem of optimizing the size of a team of robots for multi-robot exploration. We are concerned with the number of robots for a given exploration task that minimizes both exploration time and cost. Minimizing time means that the exploration should be done as fast as possible. Minimizing cost means that the number of robots and their energy consumption shou...

A hybrid watermark that consists of a robust part and a fragile part can be used to serve multiple purposes. The robust part can protect copyright information, the fragile part can detect tampering, and their combination enables identification of attacks encountered. This paper analyses an overlap and a non-overlap implementation of the robust and fragile parts in a hybrid system. The differenc...
