Exporting and innovation performance: analysis of the Annual Small Business Survey in the UK
2011
This paper analyses the determinants of the export propensity of UK small and medium-sized enterprises (SMEs) based on the 2004 Annual Small Business Survey. Particular emphasis is placed upon the relationship between innovation activities (distinguishing product from process innovation) and export performance. In general the data suggest that some 17 per cent of firms within this group sell outside the UK. Businesses that export are also characterized by high levels of innovation activity (43 per cent of exporters innovate in products, 27 per cent innovate in process and 21 per cent innovate in both). When considering product and process innovation independently we find that both impact p…
Application and assessment of IDEF3‐process flow description capture method
1995
The IDEF techniques have been developed in projects sponsored by the US Air Force in order to describe, specify and model manufacturing systems in a structured graphical form. These techniques can be classified in two categories: the “modelling” and the “descriptive” varieties. Compares two IDEF methods (one of the modelling type and one of the descriptive type) in order to represent (model or describe) two different aspects of an industrial organization. The methods compared are IDEF0, function modelling method, and IDEF3, process flow description capture method. Concludes that when considering the sequencing of the activities in process, aiming at highlighting their eventual simultaneity,…
Capability studies, helpful tools in process quality improvement
2017
Ability of processes to meet customer’quality requirements has become essential for providing competitive advantages such as cost savings, reducing the number of nonconfoming products or increasing customer satisfaction. This paper aims to conduct a capability study for a swaging process (that ensures an assembly dimension) of a key product characteristic (the outer diameter of a new part), related to the concept of capability and performance indices and how these metrics can be used and interpreted to become powerful tools for decision making. To achieve the goal of the paper, the following key aspects were analyzed: capability of the measurement system capability (gage R&R), production eq…
La idea y la forma
1997
"La idea y la forma" es un ensayo sobre la obra artística de José Antonio Orts que forma parte del catálogo de su instalación Doble Ostinato en el Ivam Centre del Carme. De la mano del concepto wittgensteiniano de 'ver como', el texto desarrolla una reflexión filosófica sobre la dimensión expresiva del objeto artístico que Orts presenta en esta instalación: un 'objeto' que aglutina lo utilitario, lo musical y lo plástico en una disposición espacio-temporal que constituye un caso de work in process en interacción con el espectador/oyente/agente que participa en la instalación.
Continuous monitoring of an intentionally-manufactured crack using an automated welding and in-process inspection system
2020
Abstract Automated weld deposition coupled with the real-time robotic Non-Destructive Evaluation (NDE) is used in this paper. For performance verification of the in-process inspection system, an intentionally embedded defect, a tungsten rod, is introduced into the multi-pass weld. A partially-filled groove (staircase) sample is also manufactured and ultrasonically tested to calibrate the real-time inspection implemented on all seven layers of the weld which are deposited progressively. The tungsten rod is successfully detected in the real-time NDE of the deposited position. The same robotic inspection system was then used to continuously monitor an intentionally-manufactured crack for 20 h.…
Scheduling a cellular manufacturing system with GA
2002
The flexible manufacturing cell scheduling problem is considered with a multi-objective approach, pursuing together makespan minimisation and the in process job wait minimisation. The formulation of the scheduling problem is discussed, analysing how to generate well suited sequences, like generalised permutation sequences, and the proper construction of a JIT timing of activities. An evolutionary sequencing algorithm based on both classic genetic operators and hybrid operators is then proposed. The hybrid operators have been introduced to construct highly fit initial population, to perform periodically a local search on the population and to maintain enough genetical diversity in the actual…
Psychotherapy Integration: A main Obstacle and Challenge
2018
Abstract Psychotherapy integration is a key trend in psychotherapy nowadays. This paper offers a critical perspective on a main obstacle and challenge for psychotherapy integration. Psychotherapy integration should be treated more as a process than as a product. For psychotherapy integration to contribute to the future of psychotherapy, it should not forget its original Exploratory spirit, avoiding and being cautious about Established approaches, and being, therefore, more a process than a product. This assumption should be related first with the core spirit of psychotherapy integration, an ongoing process of respect for different psychotherapeutic models, and an attitude of work in progres…
Bilevel heat exchanger network synthesis with an interactive multi-objective optimization method
2012
Abstract Heat exchanger network synthesis (HENS) has been an active research area for more than 40 years because well-designed heat exchanger networks enable heat recovery in process industries in an energy- and cost-efficient manner. Due to ever increasing global competition and need to decrease the harmful effects done on the environment, there still is a continuous need to improve the heat exchanger networks and their synthesizing methods. In this work we present a HENS method that combines an interactive multi-objective optimization method with a simultaneous bilevel HENS method, where the bilevel part of the method is based on grouping of process streams and building aggregate streams …
