Pattern matching is a programming language feature for selecting a handler based on the structure of data while binding names to sub-structures. By combining selection and binding, pattern matching facilitates many common tasks such as date normalization, red-black tree manipulation, conversion of XML documents, or decoding TCP/IP packets. Matchete is a language extension to Java that unifies d...

Research results from so-called “classical” separation logics are not easily ported to so-called “intuitionistic” separation logics, and vice versa. Basic questions like, “can Brookes’s soundness proof of CSL be extended to intuitionistic separation logics?” “Can the frame rule be proved independently of whether the programming language is garbage-collected?” “Can amortized resource analysis be...

The main contribution of this paper is the evaluation, on a prototype, of a class-based intra-domain routing strategy using traffic patterns and workloads based on actual Internet traffic measurements. The particular case addressed is the evaluation of the impact of the lifetime of the flows on routing and traffic performance. The importance of this issue is due to the fact that class-based rou...

The properties characterizing Sturmian words are considered for words on multiliteral alphabets. We summarize various generalizations of Sturmian words to multiliteral alphabets and enlarge the list of known relationships among these generalizations. We provide a new equivalent definition of rich words and make use of it in the study of generalizations of Sturmian words based on palindromes. We...

Studies indicate that information systems and computer science programs should place more emphasis on software design topics. Because little significant software in a commercial environment is developed using only programming skills, students without exposure to design patterns and frameworks will be ill-prepared for the workforce. This paper investigates whether PHP-based web development cours...

with respect to population growth and agricultural development in ardabil plain, vulnerability assessment of the plain aquifer is necessary for management of groundwater resources and the prevention of groundwater contamination. in this study, vulnerability of ardabil plain aquifer to pollution was evaluated by drastic method. drastic model was prepared by seven effective parameters on vulnerab...

In recent decades, several scholars have formalised Minsky’s profound insight that increasing financial fragility accompanies periods of economic stability. It must be noted, however, incisive assessments the role expectations formation with heterogeneous agents has been provided only by those contributions focusing on stock-market prices. Macroeconomic models dealing debt dynamics, other hand,...
