On Boolean topological methods of structural analysis

2001

The properties of Boolean methods of structural analysis are used to analyze the intern structure of linear or non linear models. Here they are studied on the particular example of qualitative methods of input-output analysis. First, it is shown that these methods generate informational problems like biases when working in money terms instead of percentages, losses of information, increasing of computation time, and so on. Second, considering three ways to do structural analysis, analysis from the inverse matrix, from the direct matrix and from layers (intermediate flow matrices), these methods induce topological problems; the adjacency of the adjacency cannot be defined from the inverse ma…

Biproportion et offre dominante (A propos de l'article d'André Torre ‘Sur la signification théorique du modèle d'offre multisectoriel')

1996

One replies here to partisans of the reject of the supply-driven model in input-output analysis and especially to A. Torre (Revue Economique, 5, 44, 951-970). First of all, demand-driven hypothesis (Leontief) and supply-driven hypothesis (Ghosh) are symmetrical and incompatible, what forbidden to reject the second to the motive that it depends on the first. Secondly, the results earlier obtained for France of 1970 to 1985 from the method of the biproportionnal filter show that there is so much instability in the long term in the columns than in the rows of the flow matrix. Thirdly, the assimilation of the usage of allocation coefficients to the adoption of the supply-side model is excessive.

A Note on Qualitative Input-Output Analysis

1995

International audience; The paper discusses qualitative input—output methods. It is shown that information is lost. Because the binaiy relationship constructed by qualitative methods is not transitive, the model lacks economic consistency. Qualitative methods are tending to become more sophisticated, but some problems of economic interpretation are raised.

Normalizing biproportional methods

2002

International audience; Biproportional methods are used to update matrices: the projection of a matrix Z to give it the column and row sums of another matrix is R Z S, where R and S are diagonal and secure the constraints of the problem (R and S have no signification at all because they are not identified). However, normalizing R or S generates important mathematical difficulties: it amounts to put constraints on Lagrange multipliers, non negativity (and so the existence of the solution) is not guaranteed at equilibrium or along the path to equilibrium.

The Impact of Java Applications at Microarchitectural Level from Branch Prediction Perspective

2009

The portability, the object-oriented and distributed programming models, multithreading support and automatic garbage collection are features that make Java very attractive for application developers. The main goal of this paper consists in pointing out the impact of Java applications at microarchitectural level from two perspectives: unbiased branches and indirect jumps/calls, such branches limiting the ceiling of dynamic branch prediction and causing significant performance degradation. Therefore, accurately predicting this kind of branches remains an open problem. The simulation part of the paper mainly refers to determining the context length influence on the percentage of unbiased bran…

Pellet: A Practical OWL-DL Reasoner

2007

In this paper, we present a brief overview of Pellet: a complete OWL-DL reasoner with acceptable to very good performance, extensive middleware, and a number of unique features. Pellet is the first sound and complete OWL-DL reasoner with extensive support for reasoning with individuals (including nominal support and conjunctive query), user-defined datatypes, and debugging support for ontologies. It implements several extensions to OWL-DL including a combination formalism for OWL-DL ontologies, a non-monotonic operator, and preliminary support for OWL/Rule hybrid reasoning. Pellet is written in Java and is open source.

Ketterät menetelmät ja CMMI: yhteensopivia vai -sopimattomia?

2009

  Kuhno, Hanna Maria Ketterät menetelmät ja CMMI: yhteensopivia vai -sopimattomia?/Hanna Kuhno Jyväskylä: Jyväskylän yliopisto, 2009 47 s. Kandidaatintutkielma Tässä tutkielmassa tutustutaan ketterien menetelmien soveltamiseen CMMI (Capability Maturity Model Integration) nimisen prosessien kypsyystasomallin yhteydessä. Tavoitteena on aihealueeseen tutustumisen lisäksi selvittää CMMI:n ja ketterien menetelmien yleisimmät yhteensopivuusongelmat sekä tuoda esille myös niihin kirjallisuudessa esitettyjä ratkaisuja. Niihin CMMI:n alueisiin, jotka ketterät menetelmät täyttävät hyvin, ei tutkielmassa puututa. Ketterät menetelmät ja CMMI mielletään usein toistensa vastakohdiksi, joiden yhteensovitt…

Solving NP-Complete Problems with Networks of Evolutionary Processors

2001

We propose a computational device based on evolutionary rules and communication within a network, similar to that introduced in [4], called network of evolutionary processors. An NP-complete problem is solved by networks of evolutionary processors of linear size in linear time. Some furher directions of research are finally discussed.

The effects of mobile banking application user satisfaction and system usage on bank-customer relationships

2016

This study examines mobile banking (m-banking) application usage in Finland by linking it with customer-bank relationship development. Specifically, we examine how usage is related to relationship commitment, overall satisfaction, intention to recommend the bank and future intentions to remain with the bank. A survey was used to collect data from experienced mbanking application users. In total, 273 valid responses were received. The results support the hypotheses and reveal that user satisfaction with m-banking application usage has a strong positive association with usage of m-banking applications. Usage, in turn, was positively related to all examined bank-customer relationship related v…
