An improvement of a SLAM RGB-D method with movement prediction derived from a study of visual features

This paper presents a method for the fast calculation of a robot’s egomotion using visual features. The method is part of a complete system for automatic map building and Simultaneous Location and Mapping (SLAM). The method uses optical flow to determine whether the robot has undergone a movement. If so, some visual features that do not satisfy several criteria are deleted, and then egomotion is calculated. Thus, the proposed method improves the efficiency of the whole process because not all the data is processed. We use a state-of-the-art algorithm (TORO) to rectify the map and solve the SLAM problem. Additionally, a study of different visual detectors and descriptors has been conducted to identify which of them are more suitable for the SLAM problem. Finally, a navigation method is described using the map obtained from the SLAM solution.

Retrofit of heat exchanger networks with pressure recovery of process streams at sub-ambient conditions

This paper presents a new mathematical programming model for the retrofit of heat exchanger networks (HENs), wherein the pressure recovery of process streams is conducted to enhance heat integration. Particularly applied to cryogenic processes, HENs retrofit with combined heat and work integration is mainly aimed at reducing the use of expensive cold services. The proposed multi-stage superstructure allows the increment of the existing heat transfer area, as well as the use of new equipment for both heat exchange and pressure manipulation. The pressure recovery of streams is carried out simultaneously with the HEN design, such that the process conditions (streams pressure and temperature) are variables of optimization. The mathematical model is formulated using generalized disjunctive programming (GDP) and is optimized via mixed-integer nonlinear programming (MINLP), through the minimization of the retrofit total annualized cost, considering the turbine and compressor coupling with a helper motor. Three case studies are performed to assess the accuracy of the developed approach, including a real industrial example related to liquefied natural gas (LNG) production. The results show that the pressure recovery of streams is efficient for energy savings and, consequently, for decreasing the HEN retrofit total cost especially in sub-ambient processes.

Empowering global software development with business intelligence

Context: Global Software Development (GSD) allows companies to take advantage of talent spread across the world. Most research has been focused on the development aspect. However, little if any attention has been paid to the management of GSD projects. Studies report a lack of adequate support for management’s decisions made during software development, further accentuated in GSD since information is scattered throughout multiple factories, stored in different formats and standards. Objective: This paper aims to improve GSD management by proposing a systematic method for adapting Business Intelligence techniques to software development environments. This would enhance the visibility of the development process and enable software managers to make informed decisions regarding how to proceed with GSD projects. Method: A combination of formal goal-modeling frameworks and data modeling techniques is used to elicitate the most relevant aspects to be measured by managers in GSD. The process is described in detail and applied to a real case study throughout the paper. A discussion regarding the generalisability of the method is presented afterwards. Results: The application of the approach generates an adapted BI framework tailored to software development according to the requirements posed by GSD managers. The resulting framework is capable of presenting previously inaccessible data through common and specific views and enabling data navigation according to the organization of software factories and projects in GSD. Conclusions: We can conclude that the proposed systematic approach allows us to successfully adapt Business Intelligence techniques to enhance GSD management beyond the information provided by traditional tools. The resulting framework is able to integrate and present the information in a single place, thereby enabling easy comparisons across multiple projects and factories and providing support for informed decisions in GSD management.

Experience facilitation process e o posicionamento estratégico de unidades hoteleiras

A indústria hoteleira é hoje reconhecida como uma indústria global, com produtores e consumidores espalhados por todo o mundo. Um dos grandes desafios dos nossos dias passa por maximizar a satisfação do seu consumidor e simultaneamente garantir um crescimento exponencial da procura face à concorrência. O EFP (Experience Facilitation Process) tem levantado novos desafios na gestão do turismo e da hotelaria, associado aos novos processos de gestão de negócios turísticos e à emergência de novos produtos e atributos valorizados pelos turistas. O presente estudo visa compreender até que ponto os hotéis facilitam a experiência turística e o usufruto dos seus hóspedes, maximizando a sua satisfação. Pretende-se, neste contexto, perceber se o posicionamento estratégico preconizado pelo sector coloca o enfase no elemento mais importante de uma organização, o cliente. Para o efeito, é proposto um modelo em que a EFP (Experience Facilitation Process) influencia a recomendação do hotel. O EFP é por sua vez explicado pela easiness in performance, pela tecnologia adotada, pela qualidade de F&B e pelas facilidades. O modelo foi empiricamente testado através da aplicação de uma amostra de 299 questionários recolhidos online. Tendo o modelo conceptual sido testado a partir dum modelo de equações estruturais, por recurso ao AMOS 21. Os resultados indicam que a perceção de experiência facilitada se traduz em indicadores tangíveis tais como a easiness in performance e a tecnologia. A facilitação da experiência determina a recomendação, ainda que esta recomendação seja modesta. As implicações teóricas e de gestão foram discutidas mostrando que a facilitação da experiência é um processo determinante para a satisfação dos turistas. Estes resultados empíricos, ainda que não generalizáveis, revelam a complexidade do serviço hoteleiro ao mesmo tempo que emprestam à análise do posicionamento competitivo uma nova perspetiva.

Strumenti e metodi per il miglioramento delle performance: il pilastro TPM del Focus Improvement. Il caso Philip Morris Manufacturing & Technology Bologna S.p.A.

Le peculiarità del contesto competitivo attuale richiedono alle aziende di muoversi con la massima velocità per rispondere il più rapidamente possibile al soddisfacimento delle richieste dei clienti. La ricerca di massima flessibilità non può prescindere dall’esigenza di mantenere alti livelli di efficienza produttiva e di tendere ad un continuo miglioramento dei flussi interni. L’elaborato ripercorre i passaggi fondamentali di un progetto di miglioramento delle performance di un impianto svolto nel primo semestre 2016 presso Philip Morris Manufacturing & Technology Bologna S.p.A. La metodologia utilizzata riprende strumenti, modelli e metodi dai principi alla base del Focus Improvement, primo pilastro del tempio della Total Productive Maintenance. Attraverso l’applicazione sistematica di tecniche tipiche del problem solving (ciclo di Deming) e di approcci analitici per la determinazione delle cause di guasto (curva di Pareto, Diagramma di Ishikawa), è stato possibile identificare i principali tipi di perdite (tempo, performance, difetti qualitativi) di una macchina industriale e mettere in atto gli interventi migliorativi necessari. L’analisi si conclude con la valutazione dei futuri sviluppi dello scenario, proponendo diverse alternative a seconda dell’abilità dell’organizzazione di sostenere i risultati raggiunti o addirittura di superarli.

The management improvement initiative : progress report to the General Assembly, Public Act 97-0558 /

On August 25, 2011, Governor Pat Quinn signed House Bill 1488 into law, now Public Act 97-0558 (The Act). The Act specifically directs a Management Improvement Initiative Committee (The Committee) to implement recommendations outlined in the January 2011 report to the General Assembly as required under Public Act 96-1141. The Act directs the group, formed under the auspices of Public Act 96-1141, to continue their work based on categories of recommendations. Each recommendation area has the common goal of reviewing providers from redundant monitoring, auditing, and reporting requirements. Implementing the recommendations of the Act will result in efficiency in business process for our providers, reinvestment of dollars saved from inefficient or unrealized administrative costs, and ultimately foster a network of sustainable human services providers in Illinois while increasing the level of direct service by the State agencies, contracted providers, and communities, who are all facing current economic pressures in the fiscal crisis.

Multisite, quality-improvement collaboration to optimise cardiac care in Queensland public hospitals

Objective: To evaluate changes in quality of in-hospital care of patients with either acute coronary syndromes (ACS) or congestive heart failure (CHF) admitted to hospitals participating in a multisite quality improvement collaboration. Design: Before-and-after study of changes in quality indicators measured on representative patient samples between June 2001 and January 2003. Setting: Nine public hospitals in Queensland. Study populations: Consecutive or randomly selected patients admitted to study hospitals during the baseline period (June 2001 to January 2002; n = 807 for ACS, n = 357 for CHF) and post-intervention period (July 2002 to January 2003; n = 717 for ACS, n = 220 for CHF). Intervention: Provision of comparative baseline feedback at a facilitative workshop combined with hospital-specific quality-improvement interventions supported by on-site quality officers and a central program management group. Main outcome measure: Changes in process-of-care indicators between baseline and post-intervention periods. Results: Compared with baseline, more patients with ACS in the post-intervention period received therapeutic heparin regimens (84% v 72%; P < 0.001), angiotensin-converting enzyme inhibitors (64% v 56%; P = 0.02), lipid-lowering agents (72% v 62%; P < 0.001), early use of coronary angiography (52% v 39%; P < 0.001), in-hospital cardiac counselling (65% v 43%; P < 0.001), and referral to cardiac rehabilitation (15% v 5%; P < 0.001). The numbers of patients with CHF receiving β-blockers also increased (52% v 34%; P < 0.001), with fewer patients receiving deleterious agents (13% v 23%; P = 0.04). Same-cause 30-day readmission rate decreased from 7.2% to 2.4% (P = 0.02) in patients with CHF. Conclusion: Quality-improvement interventions conducted as multisite collaborations may improve in-hospital care of acute cardiac conditions within relatively short time frames.
