Working capital management (WCM) is one of the most important decisions for all firms. The main components WCM are days sales outstanding (DSO), inventory (DIO), payable (DPO), and cash conversion cycle (CCC). Using a sample 332 Czech firms, including 20 certified firms from EFQM (European Foundation Quality Management) Model, current study explored effects on firms’ profitability. We used two ...

Behavior preservation, namely the fact that the behavior of a model is not altered by the transformations, is a crucial property in refactoring. The most common approaches to behavior preservation rely basically on checking given models and their refactored versions. In this paper we introduce a more general technique for checking behavior preservation of refactorings defined by graph transform...

Abstract Disinfecting activity test of four diphenyltin(IV) benzoate derivative compounds has been carried out. The investigated were diphenyltin (IV) di 4 aminobenzoate (DPDA) ( 2 ), chlorobenzoate (DPDC) 3 di-4-hydroxybenzoate (DPDH) and di-4-nitrobenzoate (DPDN) 5 they prepared by reacting oxide (DPO) 1 ) with benzoic acid derivatives 4-aminobenzoic (4-HABz), 4-chlorobenzoic (4-HCBz), 4-hydr...

Direct georeferencing, also referred to as direct platform orientation (DPO), is defined as direct measurement of the imaging sensor external orientation parameters (EOP), using positioning and orientation sensors, such as the Global Positioning System (GPS) and Inertial Navigation System (INS) or Inertial Measurement Unit (IMU). Imaging sensors, most frequently supported by the DPO technique, ...

The “in the large” properties of typed graph transformation systems in the double pushout framework and a double pullback variation of it, are reexamined for injective productions (for which the theory is strictly richer than in the general case). Preceding accounts utilising a fixed choice of pullbacks (whether adopted directly or via partial morphisms) are seen to be excessively sensitive to ...

Reconfigurable place/transition systems are Petri nets with initial markings and a set of rules which allow the modification of the net structure during runtime. They have been successfully used in different areas like mobile ad-hoc networks. In most of these applications the modification of net markings during runtime is an important issue. This requires the analysis of the interaction between...
