Beyond the Hype: RPA Horizon for Robot-Human Interaction

Medium and big organizations have embraced RPA in the last years bringing to light the high maturity of the technology. Current trends are towards including “human-in-the-loop” which promotes efficient ways for robot-human interaction. This is especially relevant since most real RPA projects require a collaboration between the human and the robot leading to hybrids approaches. The challenges that arise from this line can be addressed by both asynchronous (i.e., landing area or task queues where robots and humans share information) and synchronous solutions (i.e., human digital augmentation where robots provide immediate support). This paper goes in deep elaborating in these two alternatives by setting the benefits, requirements, and future research lines which are envisioned through industrial experiences. In addition, this work exposes the role of process mining in this journey since it allows for the necessary efficiency in the process analysis, time-to-market reduction, and continuous improvement that this robot-human collaboration requires.Ministerio de Economía y Competitividad TIN2016-76956-C3-2-RJunta de Andalucía CEI-12-TIC02

Adaption of the ex vivo mycobacterial growth inhibition assay for use with murine lung cells.

In the absence of a correlate(s) of protection against human tuberculosis and a validated animal model of the disease, tools to facilitate vaccine development must be identified. We present an optimised ex vivo mycobacterial growth inhibition assay (MGIA) to assess the ability of host cells within the lung to inhibit mycobacterial growth, including Bacille Calmette-Guérin (BCG) and Mycobacterium tuberculosis (MTB) Erdman. Growth of BCG was reduced by 0.39, 0.96 and 0.73 log10 CFU following subcutaneous (s.c.) BCG, intranasal (i.n.) BCG, or BCG s.c. + mucosal boost, respectively, versus naïve mice. Comparatively, a 0.49 (s.c.), 0.60 (i.n.) and 0.81 (s.c. + mucosal boost) log10 reduction in MTB CFU was found. A BCG growth inhibitor, 2-thiophenecarboxylic acid hydrazide (TCH), was used to prevent quantification of residual BCG from i.n. immunisation and allow accurate MTB quantification. Using TCH, a further 0.58 log10 reduction in MTB CFU was revealed in the i.n. group. In combination with existing methods, the ex vivo lung MGIA may represent an important tool for analysis of vaccine efficacy and the immune mechanisms associated with vaccination in the organ primarily affected by MTB disease

Why disease due to Mycobacterium tuberculosis is less common than expected in HIV-positive patients in Edinburgh

AbstractBy December 1993, only five cases of tuberculosis were observed in the 1030 HIV-positive patients in Edinburgh, U.K., although, on the basis of historical tuberculin skin test data, between four and eight new cases of tuberculosis were expected per year. Of 310 HIV-positive patients, none of the 19 (6·1%) who were tuberculin skin test positive had developed tuberculosis after 87 months (average) of follow-up. It is suggested that new or re-infection is a more common cause of tuberculosis in HIV-positive patients than reactivation. Restriction fragment length polymorphism typing of Mycobacterium tuberculosis strains could confirm this hypothesis and support currently suggested additional infection control procedures

Amperometric and spectrophotometric determination of carbaryl in natural waters and commercial formulations

The work presented describes the development and evaluation of two flow-injection analysis (FIA) systems for the automated determination of carbaryl in spiked natural waters and commercial formulations. Samples are injected directly into the system where they are subjected to alkaline hydrolysis thus forming 1-naphthol. This product is readily oxidised at a glassy carbon electrode. The electrochemical behaviour of 1-naphthol allows the development of an FIA system with an amperometric detector in which 1-naphthol determination, and thus measurement of carbaryl concentration, can be performed. Linear response over the range 1.0×10–7 to 1.0×10–5 mol L–1, with a sampling rate of 80 samples h–1, was recorded. The detection limit was 1.0×10–8 mol L–1. Another FIA manifold was constructed but this used a colorimetric detector. The methodology was based on the coupling of 1-naphthol with phenylhydrazine hydrochloride to produce a red complex which has maximum absorbance at 495 nm. The response was linear from 1.0×10–5 to 1.5×10–3 mol L–1 with a detection limit of 1.0×10–6 mol L–1. Sample-throughput was about 60 samples h–1. Validation of the results provided by the two FIA methodologies was performed by comparing them with results from a standard HPLC–UV technique. The relative deviation was <5%. Recovery trials were also carried out and the values obtained ranged from 97.0 to 102.0% for both methods. The repeatability (RSD, %) of 12 consecutive injections of one sample was 0.8% and 1.6% for the amperometric and colorimetric systems, respectively

A Method to Improve the Early Stages of the Robotic Process Automation Lifecycle

The robotic automation of processes is of much interest to organizations. A common use case is to automate the repetitive manual tasks (or processes) that are currently done by back-office staff through some information system (IS). The lifecycle of any Robotic Process Automation (RPA) project starts with the analysis of the process to automate. This is a very time-consuming phase, which in practical settings often relies on the study of process documentation. Such documentation is typically incomplete or inaccurate, e.g., some documented cases never occur, occurring cases are not documented, or documented cases differ from reality. To deploy robots in a production environment that are designed on such a shaky basis entails a high risk. This paper describes and evaluates a new proposal for the early stages of an RPA project: the analysis of a process and its subsequent design. The idea is to leverage the knowledge of back-office staff, which starts by monitoring them in a non-invasive manner. This is done through a screen-mousekey- logger, i.e., a sequence of images, mouse actions, and key actions are stored along with their timestamps. The log which is obtained in this way is transformed into a UI log through image-analysis techniques (e.g., fingerprinting or OCR) and then transformed into a process model by the use of process discovery algorithms. We evaluated this method for two real-life, industrial cases. The evaluation shows clear and substantial benefits in terms of accuracy and speed. This paper presents the method, along with a number of limitations that need to be addressed such that it can be applied in wider contexts.Ministerio de Economía y Competitividad TIN2016-76956-C3-2-

South Africa's business process outsourcing services sector: Lessons for Western-based client firms

Since 2008, South Africa has become one of the world's upcoming offshore destinations for business process outsourcing (BPO), a market estimated to be worth $US 182 billion globally by 2013. Western-based client firms evaluating South Africa as a BPO destination must consider the country's relative value against alternative locations. Client firms also have a number of engagement models from which to choose, inclucling outsourcing, erecting a captive centre, or acquiring an existing BPO business. The research finds that, for the UK, US, and Australian client companies in this study, South Africa's value proposition is not just based on costs as other locations are often cheaper. South Africa's value proposition is about overall economic value, high quality service and staff, strong cultural compatibility, and a favourable time zone. The findings reveal that South Africa complements the global portfolio for Western-based client firms that already have BPO centres in Inclia, the Philippines, and Eastern Europe. Moreover, whether client firms build or buy services from South Africa, the research identifies clistinctive risks that need to be mitigated by investing in and effectively governing the business processes performed offshore. Finally, from the case study research, this article identifies management lessons for leveraging South Africa's identifiable BPO service advantage

Towards an OpenSource Logger for the Analysis of RPA Projects

Process automation typically begins with the observation of humans conducting the tasks that will be eventually automated. Sim ilarly, successful RPA projects require a prior analysis of the undergo ing processes which are being executed by humans. The process of col lecting this type of information is known as user interface (UI) logging since it records the interaction against a UI. Main RPA platforms (e.g., Blueprism and UIPath) incorporate functionalities that allow the record ing of these UI interactions. However, the records that these platforms generate lack some functionalities that large-scale RPA projects require. Besides, they are only understandable by the proper RPA platforms. This paper presents an extensible and multi-platform OpenSource UI logger that generate UI logs in a standard format. This system collects information from all the computers it is running on and sends it to a central server for its processing. Treatment of the collected information will allow the creation of an enriched UI log which can be used, among others purposes, for smart process analysis, machine learning training, the creation of RPA robots, or, being more general, for task mining .Ministerio de Economía y Competitividad TIN2016-76956-C3-2-R (POLOLAS)Junta de Andalucía CEI-12-TIC021Centro para el Desarrollo Tecnol´ogico Industrial (CDTI) P011-19/E0
