We present an approach to the study of nondeterministic programs, consisting essentially in using binary relations as semantic objects representing the input-output behaviour of programs. These relations include an explicit representation of non-terminating computations. Based on the relational model we introduce a weakest precondition total correctness predicate transformer. We then show how t...

Recent work has extended Kozen's probabilistic semantics 8, 9] to include demonic nondeterminism both at the operational 5] and the logical level 12]. That makes it now possible in principle to treat probabilistic program development with the same standards of rigour that apply, when appropriate, to imperative programming 3]. In this report we treat several practical aspects of the new models, ...

In the effort to develop critical cyberphysical systems, existing computing formalisms are extended to include continuous behaviour. This may happen in a way that neglects elements necessary for correct continuous properties and correct physical properties. A simple language is taken to illustrate this. Issues and risks latent in this kind of approach are identified and discussed under the umbr...

Minimally processed vegetables (MPV) are economically important commodities due to a combination of factors such as convenience, healthiness nd desirable sensory characteristics. These commodities are susceptible to microbiological invasion due to the presence of cut surfaces causing both icrobiological and physiological mechanisms to be possible limitations for the sensory shelf life. This rev...

Edible macroalgae (i.e., ‘seaweeds’) are a nutritious and sustainable alternative to animal-based proteins. However, consumption of seaweeds in Western countries remains low, little is known about individual drivers acceptance. The aim this study was further explore the consumer acceptability seaweed-based food products UK. In an online (N = 476), participants were presented with general descri...

Purpose The COVID-19 has brought with it valuable opportunities for the retail sector. Notably, online channels have assumed a key role businesses that can rely less on physical due to pandemic's restrictions. Within this context, study aims identify main antecedents leading formation of male and female customers' continuance intention using food delivery services (OFDS) in restaurant industry....

This study had two specific objectives which are: Establish the effect of credit risk management on performance commercial banks in DRC. And to identify most healthiness Commercial In this we have responded questions: Is there a relationship between and DRC? What’s bank After analysis concluded that has not any impact with financial DRC best was BCDC during time covered by

Abstract This research is aimed to detect the area in paddy field that have damage leaves. It hard check disease and pest infestation by human vision. Position of viewer into damaged leaves does ensure see intact field. In this UAV was utilized take picture healthy from above. Aerial position will benefit completely seen. To healthiness leave area, attached Rasberry Pi 4, installed image proces...
