Asphalt materials have a very wide range of applications in roads, but with the increase traffic pressure and intensification cracking rutting traditional asphalt pavements, there is an urgent need to further improve performance materials. In this paper, composite containing 10%, 20%, 30% trinidad lake (TLA) 0%, 2%, 3%, 4% styrene-butadiene rubber (SBR) were prepared. Their basic properties mix...

Designers of concurrent and distributed algorithms usually express them using pseudo-code. In contrast, most verification techniques are based on more mathematically-oriented formalisms such as state transition systems. This conceptual gap contributes to hinder the use of formal verification techniques. Leslie Lamport introduced PlusCal, a high-level algorithmic language that has the “look and ...

BACKGROUND Microbiological laboratories seek technologically innovative solutions to cope with large numbers of samples and limited personnel and financial resources. One platform that has recently become available is the Kiestra Total Laboratory Automation (TLA) system (BD Kiestra B.V., the Netherlands). This fully automated sample processing system, equipped with digital imaging technology, a...

This paper presents an encoding of a non-temporal fragment of the TLA language, which includes untyped set theory, functions, arithmetic expressions, and Hilbert’s ε operator, into many-sorted firstorder logic, the input language of state-of-the-art smt solvers. This translation, based on encoding techniques such as boolification, injection of unsorted expressions into sorted languages, term re...

This work presents an electromagnetic and dynamic performance analysis of a two-phase permanent-magnet tubular linear actuator (PM-TLA) prototype; an electromagnetic finite-element model is proposed and dynamic performance of the system drive, composed of PM-TLA prototype and associated power electronic devices in a control loop, is analyzed using simulation software tools.

Transfer protocols are composed from basic protocol mechanisms and accordingly a complex protocol can be veriied by a series of relatively simple mechanism proofs. Our approach applies L. Lamport's Temporal Logic of Actions (TLA). It is based on a modular compositional TLA-style and supports the analysis of exibly conngured high-speed transfer protocols.

TLA (the Temporal Logic of Actions) is a linear temporal logic for specifying and reasoning about reactive systems. We define a subset of TLA whose formulas are amenable to validation by animation, with the intent to facilitate the communication between domain and solution experts in the design of reactive systems.

Hume is a Turing-complete programming language, designed to guarantee space and time bounds whilst still working on a high-level. Formal properties of Hume programs, such as invariants and transformations, have previously been verified using the temporal logic of actions (TLA). TLA properties are verified in an inductive way, which often requires lemma discovery or generalisations. Rippling was...

SAŽETAK: U radu je analiziran utjecaj mikrostaništa na fiziološke značajke i vegetativni rast hrasta lužnjaka. Istraživanje je provedeno na dvije pokusne plohe koje se odlikuju različitim kemijskim značajkama, sadržajem vlage i temperaturom tla. Cilj rada bio je utvrditi utjecaj različitih kemijskih značajki tla na vegetativni rast i intenzitet fotosinteze hrasta lužnjaka, kao i odnos koncentra...

One approach to verify the correctness of a system is to prove that it implements an executable (specification) model whose correctness is more obvious. Here, we define a kind of automata whose state is the product of values of multiple variables that we name State Transition System (STS). We define the semantics of TLA+ (specification language of the Temporal Logic of Actions) constructs using...
