Remote control of devices using an 8-bit embedded XML & dynamic web-server in a SmartHouse environment : a thesis presented in partial fulfilment of the requirements for the degree of Master of Engineering in Computer Systems Engineering at Massey University

This paper focuses on an Embedded System known as "TCP/IC" and its role in the "house of the future" - the SmartHouse. Overall, the aim of the TCP/IC was to design a device which could interact with a user (or AI control system) and allow for the control of various attached peripherals remotely. Although such a device could well be used as a standalone device to aid in home-automation, this paper focuses on its use in a SmartHouse environment - one where a number of these devices are networked and controlled by a central AI. The different technologies and protocols involved in the implementation of the TCP/IC, along with its two primary interfaces, namely HTML (used for user interaction) and XML (used for machine interaction) are also discussed. The reader will also be introduced to Embedded Systems and the various design principles involved in the creation of quality Embedded Systems. Core-concepts of home-automation and its logical extension, the SmartHouse are also covered in detail. Various additional interfaces (e.g. Web, XML, custom-formatted text) are also discussed and compared, as are the result of my work and some ideas for future implementations

Impact of community structure on information transfer

The observation that real complex networks have internal structure has important implication for dynamic processes occurring on such topologies. Here we investigate the impact of community structure on a model of information transfer able to deal with both search and congestion simultaneously. We show that networks with fuzzy community structure are more efficient in terms of packet delivery than those with pronounced community structure. We also propose an alternative packet routing algorithm which takes advantage of the knowledge of communities to improve information transfer and show that in the context of the model an intermediate level of community structure is optimal. Finally, we show that in a hierarchical network setting, providing knowledge of communities at the level of highest modularity will improve network capacity by the largest amount

Documentation of CORTAX

CORTAX is applied in Bettendorf et al. (2006), a simulation study on the economic and welfare implications of reforms in corporate income taxation. This technical documentation of the model consists of the derivation and listing of the equations of the model and a justification of the calibration.

Hadamard matrices of order 4(2p + 1)

AbstractIt is shown in this paper that if p is a prime and q = 2p − 1 is a prime power, then there exists an Hadamard matrix of order 4(2p + 1)

Who benefits from tax competition in the European Union?

Statutory tax rates have declined in the European Union in the recent decades. An applied general equilibrium model on corporate taxation sheds light on the economic and welfare implications of tax rate reforms. Domestic distortions proof highly relevant as even unilateral reductions of the corporate income tax rate might reduce welfare if the labour tax rate has to be increased. Profit shifting induces countries to underbid each others tax rates, but this effect is sizable only if two countries are closely linked. The harmful external effects of CIT rate reductions are limited, which reduces the need for European coordination of CIT rates.

Does employment affect productivity?

We investigate the trade-off between employment and labour productivity in a panel of OECD countries in 1970-2003. The endogeneity of employment is shown to matter crucially for assessing its effect on productivity. Estimating a structural model with 3SLS, where employment depends on demographic variables and labour market institutions, we find that employment tends to boost productivity. Literature ignoring the endogeneity of employment, including our own OLS results, incorrectly finds a negative or insignificant effect from employment on productivity. The productivity gain is, however, not a guaranteed by-product of additional employment, as regressions with rolling windows reveal.

Will corporate tax consolidation improve efficiency in the EU?

Consolidation of the tax base in the European Union is expected to curve compliance costs and reduce profit shifting. A number of proposals for consolidation from the European Commission are simulated with the applied general equilibrium model CORTAX. We show that the benefits from consolidation are offset by two weaknesses in the proposals for a common consolidated tax base. Formula apportionment, which is needed to allocate the consolidated taxable profits across jurisdictions, creates new tax planning possibilities for MNEs and allows them to benefit from existing tax rate differentials in the European Union. In addition, it triggers tax competition as member states may attract foreign investment by reducing their tax rates. The second distortion is an unlevel playing field, which is introduced if only part of the firms participate in the consolidation. The gains from consolidation can be fully grasped if it is obliged for all firms and if it is accompanied by a harmonisation of the tax rate.
