A good way to gain a deeper understanding of modern operating-system concepts is to get your hands dirty — to take apart the code for an operating system to see how it works at a low level, to build significant pieces of the operating system yourself, and to observe the effects of your work. An operating-system course project provides this opportunity to see how you can use basic concepts to so...

The B-Method is a method for the stepwise derivation of sequential programs. In this paper we show how the B-Method can be used for designing distributed systems by embedding action systems within this method. The action system formalism is designed for the construction of parallel and distributed systems in a stepwise manner within the refinement calculus. We describe how action systems are wr...

Removal of boron from aqueous environments (soil and water) is difficult, because it is present as B(OH)3 and B(OH)4- species. This research was done to study the sorption of boron by HDTMA-modified zeolite. The sorption of B on modified zeolite was studied as a function of pH (B concentration: 1 and 10 mg L-1) in the range of 6-9.5, and as a function of ionic strength (0.03 and 0.06 M Ca(NO3)2...

implicit and unobserved errors and vulnerabilities issues usually arise in cryptographic protocols and especially in authentication protocols. this may enable an attacker to make serious damages to the desired system, such as having the access to or changing secret documents, interfering in bank transactions, having access to users’ accounts, or may be having the control all over the syste...
