Standardization efforts: The relationship between knowledge dimensions, search processes and innovation outcomes

We explore how a standardization effort (i.e., when a firm pursues standards to further innovation) involves different search processes for knowledge and innovation outcomes. Using an inductive case study of Vanke, a leading Chinese property developer, we show how varying degrees of knowledge complexity and codification combine to produce a typology of four types of search process: active, integrative, decentralized and passive, resulting in four types of innovation outcome: modular, radical, incremental and architectural. We argue that when the standardization effort in a firm involves highly codified knowledge, incremental and architectural innovation outcomes are fostered, while modular and radical innovations are hindered. We discuss how standardization efforts can result in a second-order innovation capability, and conclude by calling for comparative research in other settings to understand how standardization efforts can be suited to different types of search process in different industry contexts.

Image-based delineation and classification of built heritage masonry

[EN]Fundación Zain is developing new built heritage assessment protocols. The goal is to objectivize and standardize the analysis and decision process that leads to determining the degree of protection of built heritage in the Basque Country. The ultimate step in this objectivization and standardization effort will be the development of an information and communication technology (ICT) tool for the assessment of built heritage. This paper presents the ground work carried out to make this tool possible: the automatic, image-based delineation of stone masonry. This is a necessary first step in the development of the tool, as the built heritage that will be assessed consists of stone masonry construction, and many of the features analyzed can be characterized according to the geometry and arrangement of the stones. Much of the assessment is carried out through visual inspection. Thus, this process will be automated by applying image processing on digital images of the elements under inspection. The principal contribution of this paper is the automatic delineation the framework proposed. The other contribution is the performance evaluation of this delineation as the input to a classifier for a geometrically characterized feature of a built heritage object. The element chosen to perform this evaluation is the stone arrangement of masonry walls. The validity of the proposed framework is assessed on real images of masonry walls.

Estudio sobre un sistema de radiocomunicaciones ferroviarias de acuerdo al paradigma 4G

No hay duda de que el ferrocarril es uno de los símbolos del avance tecnológico y social de la humanidad, y su imparable avance desde el primer tercio del Siglo XIX así lo atestigua. No obstante, a lo largo de gran parte de su historia se ha mostrado algo renuente a abrazar ciertas tecnologías, lo que le ha causado ser tachado de conservador. Sin embargo, en los últimos años, coincidiendo con el auge masivo de los trenes de alta velocidad, los metropolitanos y los tranvías, muchas tecnologías han ido penetrando en el mundo del ferrocarril. La que hoy nos ocupa es una de las que mayor valor añadido le ha proporcionado (y que probablemente le proporcionará también en el futuro): las comunicaciones móviles. Actualmente el uso de este tipo de tecnologías en el entorno ferroviario puede calificarse como de inicial o, por seguir la nomenclatura de las comunicaciones móviles públicas, de segunda generación. El GSM-R en las líneas de alta velocidad es un caso (aunque de éxito al fin y al cabo) que define perfectamente el estado del arte de las comunicaciones móviles en este entorno, ya que proporcionó un gran valor añadido a costa de un gran esfuerzo de estandarización; ha supuesto un importante salto adelante en el campo de la fiabilidad de este tipo de sistemas, aunque tiene unas grandes limitaciones de capacidad y graves problemas de escalabilidad. Todo hace pensar que en 2025 el sustituto de GSM-R deberá estar en el mercado. En cualquier caso, se debería abandonar la filosofía de crear productos de nicho, que son extraordinariamente caros, y abrazar las filosofías abiertas de las redes de comunicaciones públicas. Aquí es donde LTE, la última gran estrella de esta familia de estándares, puede aportar mucho valor. La idea subyacente detrás de esta Tesis es que LTE puede ser una tecnología que aporte gran valor a las necesidades actuales (y probablemente futuras) del sector del ferrocarril, no solamente en las líneas y trenes de alta velocidad, sino en las denominadas líneas convencionales y en los metros y tranvías. Dado que es un campo aún a día de hoy que dista bastante de estar completamente estudiado, se ha explorado la problemática de la propagación electromagnética en los diferentes entornos ferroviarios, como pueden ser los túneles de metro y la influencia de las estructuras de los trenes. En este sentido, se ha medido de forma bastante exhaustiva en ambos entornos. Por otro lado, dado que los sistemas multiantena son uno de los pilares fundamentales de los modernos sistemas de comunicaciones, se ha verificado de forma experimental la viabilidad de esta tecnología a la hora de implementar un sistema de comunicaciones trentierra en un túnel. Asimismo, de resultas de estas medidas, se ha comprobado la existencia de ciertos fenómenos físicos que pueden suponer una merma en la eficiencia de este tipo de sistemas. En tercer lugar, y dado que uno de los grandes desafíos de las líneas de alta velocidad está provocado por la gran celeridad a la que se desplazan los trenes, se ha explorado la influencia de este parámetro en la eficiencia global de una red completa de comunicaciones móviles. Por supuesto, se ha hecho especial hincapié en los aspectos relacionados con la gestión de la movilidad (traspasos o handovers Por último, a modo de cierre de la Tesis, se ha tratado de identificar los futuros servicios de comunicaciones que aportarán más valor a las explotaciones ferroviarias, así como los requisitos que supondrán para las redes de comunicaciones móviles. Para los casos antes enunciados (propagación, sistemas multiantena, movilidad y desafíos futuros) se proporcionan las contribuciones ya publicadas en revistas y congresos internacionales, así como las que están enviadas para su revisión. ABSTRACT There is almost no doubt that railways are one of the symbols of the technological and social progress of humanity. However, most of the time railways have been somewhat reluctant to embrace new technologies, gaining some reputation of being conservative. But in the last years, together with the massive boom of high speed lines, subways and trams all over the world, some technologies have broken through these conservative resistance. The one which concerns us now is one of the most value-added (both today and in the future): mobile communications. The state-of-the-art of these technologies in the railway field could be called as incipient, or (following the mobile communications’ notation) ‘second generation’. GSM-R, the best example of mobile communications in railways is a success story that shows perfectly the state-of-the-art of this field: it provided a noticeable mark-up but also required a great standardization effort; it also meant a huge step forward in the reliability of these systems but it also needs to face some scalability issues and some capacity problems. It looks more than feasible that in 2025 the alternative to GSM-R should be already available. Anyway, the vision here should be forgetting about expensive niche products, and embracing open standards like public mobile communications do. The main idea behind this Thesis is that LTE could be a technology that provides a lot of added value to the necessities of the railways of today and the future. And not only to highspeed lines, but also to the so-called conventional rail, subways and tramways. Due to the fact that even today, propagation in tunnels and influence of car bodies is far from being full-studied, we measured in a very exhaustive way the EM propagation in these two environments. Also, multiantenna systems are one of the basic foundations of the modern communications systems, so we experimentally verified the feasibility of using such a system in a train-towayside in a tunnel. Moreover, from the measurements carried out we proved the existence of some physical phenomena that could imply a decrease in the performance of these multiantenna systems. In third place, we have explored the influence of high-speed in the whole performance of the network, from the mobility management point-of-view. This high-speed movement is one of the most relevant challenges for the mobile communications networks. The emphasis was placed on the mobility aspects of the radio resource management. Finally, the Thesis closure is an identification of the future communication services that could provide a bigger addition of value to railways, and also the requirements that imply to mobile communications networks. For all the previous for scenarios depicted before (propagation, multiantenna systems, mobility and challenges) we provide some contributions already published (or submitted for revision or still in progress) on publications and international conferences.

On the standardization of the fishing effort

In this note we demonstrate that the use of an index to standardize the fishing effort using the cpue of a standard vessel or gear is mistaken, once the cpues- catch per unit of total effort after standardization is similar to cpues - catch per unit of effort of the standard vesel or gear arbitrarily chosen.

CAD Standardization in Construction – a Process View

There has been a demand for uniform CAD standards in the construction industry ever since the large-scale introduction of computer aided design systems in the late 1980s. While some standards have been widely adopted without much formal effort, other standards have failed to gain support even though considerable resources have been allocated for the purpose. Establishing a standard concerning building information modeling has been one particularly active area of industry development and scientific interest within recent years. In this paper, four different standards are discussed as cases: the IGES and DXF/DWG standards for representing the graphics in 2D drawings, the ISO 13567 standard for the structuring of building information on layers, and the IFC standard for building product models. Based on a literature study combined with two qualitative interview studies with domain experts, a process model is proposed to describe and interpret the contrasting histories of past CAD standardisation processes.

Estimation of Standardized Effort in the Heterogeneous Gulf of Mexico Shrimp Fleet

In this paper we estimate nominal and standardized shrimping effort in the Gulf of Mexico for the years 1965 through 1993. We accomplish this by first developing a standardization method (model) and then an expansion method (model). The expansion model estimates nominal days fished for noninterview landings data. The standardization model converts nominal days fished to standard days fished. We then characterize the historical trends of the penaeid shrimp fishery byvessel configuration, relative fishing power, and nominal and standardized effort. Wherever possible, we provide comparison with previous estimates by the National Marine Fisheries Service, NOAA.

MDNR-NOAA trawl standardization study

Long-term living resource monitoring programs are commonly conducted globally to evaluate trends and impacts of environmental change and management actions. For example, the Woods Hole bottom trawl survey has been conducted since 1963 providing critical information on the biology and distribution of finfish and shellfish in the North Atlantic (Despres-Patango et al. 1988). Similarly in the Chesapeake Bay, the Maryland Department of Natural Resources (MDNR) Summer Blue Crab Trawl survey has been conducted continuously since 1977 providing management-relevant information on the abundance of this important commercial and recreational species. A key component of monitoring program design is standardization of methods over time to allow for a continuous, unbiased data set. However, complete standardization is not always possible where multiple vessels, captains, and crews are required to cover large geographic areas (Tyson et al. 2006). Of equal issue is technological advancement of gear which serves to increase capture efficiency or ease of use. Thus, to maintain consistency and facilitate interpretation of reported data in long-term datasets, it is imperative to understand and quantify the impacts of changes in gear and vessels on catch per unit of effort (CPUE). While vessel changes are inevitable due to ageing fleets and other factors, gear changes often reflect a decision to exploit technological advances. A prime example of this is the otter trawl, a common tool for fisheries monitoring and research worldwide. Historically, trawl nets were constructed of natural materials such as cotton and linen. However modern net construction consists of synthetic materials such as polyamide, polyester, polyethylene, and polypropylene (Nielson et. al. 1983). Over the past several decades, polyamide materials which will be referred to as nylon, has been a standard material used in otter trawl construction. These trawls are typically dipped into a latex coating for increased abrasion resistance, a process that is referred to as “green dipped.” More recently, polyethylene netting has become popular among living resource monitoring agencies. Polyethylene netting, commonly known as sapphire netting, consists of braided filaments that form a very durable material more resistant to abrasion than nylon. Additionally, sapphire netting allows for stronger knot strength during construction of the net further increasing the net’s durability and longevity. Also, sapphire absorbs less water with a specific gravity near 0.91 allowing the material to float as compared to nylon with specific gravity of 1.14 (Nielson et. al. 1983). This same property results in a light weight net which is more efficient in deployment, retrieval and fishing of the net, particularly when towing from small vessels. While there are many advantages to the sapphire netting, no comparative efficiency data is available for these two trawl net types. Traditional nylon netting has been used consistently for decades by the MDDNR to generate long term living resource data sets of great value. However, there is much interest in switching to the advanced materials. In addition, recent collaborative efforts between MDNR and NOAA’s Cooperative Oxford Laboratory (NOAA-COL) require using different vessels for trawling in support of joint projects. In order to continue collaborative programs, or change to more innovative netting materials, the influence of these changes must be demonstrated to be negligible or correction factors determined. Thus, the objective of this study was to examine the influence of trawl net type, vessel type, and their interaction on capture efficiency.

Standardization of project management processes

Software development is a discipline that is almost as old as the history of computers. With the advent of the Internet and all of its related technologies, software development has been on high demand. But, and especially in SME (small and medium enterprise), this was not accompanied with a comparable effort to develop a set of sustainable and standardized activities of project management, which lead to increasing inefficiencies and costs. Given the actual economic situation, it makes sense to engage in an effort to reduce said inefficiencies and rising costs. For that end, this work will analyze the current state of software development’s project management processes on a Portuguese SME, along with its problems and inefficiencies in an effort to create a standardized model to manage software development, with special attention given to critical success factors in an agile software development environment, while using the best practices in process modeling. This work also aims to create guidelines to correctly integrate these changes in the existing IS structure of a company.

Test Analysis Tool (TATo). A new tool for standardization of time series in maritime and port environment

During the last decades, Puertos del Estado and research groups have developed a huge effort on numerical an physical monitoring. This effort has led to the necessity to implement a tool to standardize, store and process all gathered data. The Test Analysis Tool (TATo) is described in the paper.

Position Paper: Improving Source Code Reuse through Documentation Standardization

In the context of Software Reuse providing techniques to support source code retrieval has been widely experimented. However, much effort is required in order to find how to match classical Information Retrieval and source code characteristics and implicit information. Introducing linguistic theories in the software development process, in terms of documentation standardization may produce significant benefits when applying Information Retrieval techniques. The goal of our research is to provide a tool to improve source code search and retrieval In order to achieve this goal we apply some linguistic rules to the development process.

Standardized geo-referenced catch, fishing effort and length-frequency data for the Indian Ocean Bigeye Tuna, Thunnus obesus (1952-2014)

Geo-referenced catch and fishing effort data of the bigeye tuna fisheries in the Indian Ocean over 1952-2014 were analysed and standardized to facilitate population dynamics modelling studies. During this sixty-two years historical period of exploitation, many changes occurred both in the fishing techniques and the monitoring of activity. This study includes a series of processing steps used for standardization of spatial resolution, conversion and standardization of catch and effort units, raising of geo-referenced catch into nominal catch level, screening and correction of outliers, and detection of major catchability changes over long time series of fishing data, i.e., the Japanese longline fleet operating in the tropical Indian Ocean. A total of thirty fisheries were finally determined from longline, purse seine and other-gears data sets, from which 10 longline and four purse seine fisheries represented 96% of the whole historical catch. The geo-referenced records consists of catch, fishing effort and associated length frequency samples of all fisheries.
