A Python-OpenCV based software for processing single-bacterium tracking microscopy videos.

Real-time single-bacterium tracking (SBT) is a powerful microscopy technique that allows for direct observation of the motility of individual bacteria. This technique requires microscopy video processing methods to localize individual bacteria from microscopy videos, followed by obtaining bacterial trajectories by linking the localizations in successive video frames. These analysis steps are usually labor-intensive. In addition, many existing analysis softwares are developed using commercial programming languages, which makes it difficult to be further developed and used for larger contexts of usage. In this regard, a Python-OpenCV based software is presented which is capable of obtaining bacterial trajectories from SBT microscopy videos. The developed software does not require additional commercial software licenses. Also, the software can perform video processing and bacterial trajectory extraction steps in an automated way. The developed open-source software could thus be listed as one of the useful tools for related quantitative investigations. This work is supported by the National Natural Science Foundation of China (NSFC) under grant number 12104405.

Modelling programming languages – appropriate tools?

This paper examines the issue of modelling languages as software tools for the construction and analysis of economic models. Modelling languages are intermediate level software tools that fit between the conventional commercial programming languages (such as C++ and Java) and the higher level applications packages (such as specific econometric packages). They try to blend the advantages of both the higher level and lower level tools. This paper examines these languages for use in the construction of economic models. Specifically, it examines the issue of whether such a language is the appropriate software tool for an economic modeller. It uses the modelling language MATLAB together with a number of illustrative examples to examine the use of these software tools with dynamic economic models.

The impact of software enhancement on software reliability

This paper exploits the 'relationship between functional-enhancement (FE) activity and the distribution of software defects' to develop a discriminant model that identifies high-risk program modules, 'FE activity' and 'defect data captured during the FE of a commercial programming language processing utility' serve to fit and test the predictive quality of this model. The model misclassification rates demonstrate that FE information is sufficient for developing discriminant models identifying high-risk program modules. Consideration of the misclassified functions leads us to suggest that: (1) the level of routines in the calling hierarchy introduces variation in defect distribution; and (2) the impact of a defect indicates the risk that it presents. Thus consideration of defect impact can improve the discriminant results.

The growth of a commercial programming language

Publisher Summary This chapter discusses the growth of a commercial programming language SEAL (Standard Electronic Accounting Language), which is designed for use initially with the Stantec Data Processing System. In general, SEAL is a one or two address language, in that one or two operands may be specified in each command, that is, in each line of coding. The manner in which the lengths of numeric fields are given on Data Descriptions ensures that they may be transferred to another machine of different word length, if the new machine has a longer word length the object program will be more efficient, if shorter then it will be less efficient. The rules of SEAL merely ensure that no packing of operands, several to a word, takes place in machines where this packing would be uneconomic. The users of data processing equipment might be induced to consider their requirements for a programming language in the light of current developments in business languages. The current fashion, of which SEAL is an example, is for English language programming.
