traceability is an ability of system to provide status reports or records pertaining of the current situation in the past. in production systems, traceability to track the product or lot of a product and access to records in the entire production process (or part of the process) of the raw material to finished product that purchased and consumed by customer will be applied. traceability in prod...

there are different studies in urban literature on the determinants of urban growth, from the theoretical and empirical points of view. the most completed theoretical model is henderson model (1988, 1997, and 1999), which is tested by some empirical studies. as henderson model shows, the set of national product, specialization and technological progress are the determinants of urban growth. usi...

In this paper, we consider Serrin’s overdetermined problems in warped product manifolds and prove type rigidity results by using the [Formula: see text]-function approach introduced Weinberger.

Pyrolysis of low density polyethylene (LDPE) by equilibrium fluid catalytic cracking (FCC) was studied in a stirred reactor under different process parameters. In this work, the effect of process parameters such as degradation temperature (420-510°C), catalyst/polymer ratio (0-60%), carrier gas type (H2, N2, ethylene, propylene, Ar and He), residence time and agitator speed (0-300 rpm) on the c...

in the traditional systems of irrigation and exploitation of water sources, especially the water sources behind dams, there isn't regular and consistent plan for their management and this can be caused the weakness of irrigation performance. in this connection, using both of optimization methods and geospatioal information system (gis) together can improve the performance of irrigation pro...

In this paper we introduce the concept of geometrically quasiconvex functions on the co-ordinates and establish some Hermite-Hadamard type integral inequalities for functions defined on rectangles in the plane. Some  inequalities for product of two geometrically quasiconvex functions on the co-ordinates are considered.
