Towards a BIM-based energy rating system

Governments in Australia are faced with policy implementation that mandates higher energy efficient housing (Foran, Lenzen & Dey 2005). To this effect, the National Construction Code (NCC) 2013 stipulates the minimum energy performance for residential buildings as 114MJ/m2 per annum or 6 stars on an energy rating scale. Compliance with this minimum is mandatory but there are several methods through which residential buildings can be rated to comply with the deemed to satisfy provisions outlined in the NCC. FirstRate5 is by far the most commonly used simulation software used in Victoria, Australia. Meanwhile, Building Information Modelling (BIM), using software such as ArchiCAD has gained a foothold in the industry. The energy simulation software within ArchiCAD, EcoDesigner, enables the reporting on the energy performance based on BIM elements that contain thermal information. This research is founded on a comparative study between FirstRate5 and EcoDesigner. Three building types were analysed and compared. The comparison finds significant differences between simulations, being, measured areas, thermal loads and potentially serious shortcomings within FirstRate5, that are discussed along with the future potential of a fully BIM-integrated model for energy rating certification in Victoria. © 2014, The Association for Computer-Aided Architectural Design Research in Asia (CAADRIA), Hong Kong.

An improved TIGER2 implementation for NAMD suitable for the Blue Gene architecture

Here we present an improved implementation of the TIGER2 Replica Exchange Molecular Dynamics (REMD) method, using the replica exchange Application Programming Interface (API) found in contemporary versions of the NAMD Molecular Dynamics Package. The implementation takes the form of a TCL script which is used in conjunction with the standard configuration file. This implementation is validated against a previous TIGER2 implementation, as well as data reported for the original TIGER2 simulations. Our implementation is compatible with a range of architectures; crucially it enables the use of this wrapper with the BlueGene/Q architecture, in addition to the x86 architecture.

Opting only in: Contractarians, waiver of liability provisions, and the race to the bottom

This paper will test the core claim of scholars in the nexus of contracts tradition—that private ordering as a process of bargaining creates optimal rules. We do this by analyzing empirical evidence in the context of waiver of liability provisions. These provisions allow companies to eliminate monetary damages for breach of the duty of care through amendments to the articles of incorporation. With all states allowing some form of these provisions, they represent a good laboratory to examine the bargaining process between management and shareholders. The contractarian approach would suggest that shareholders negotiate with management to obtain agreements that are in their best interests. If a process of bargaining is at work as they claim, the opt-in process for waiver of liability provisions ought to generate a variety of approaches. Shareholders wanting a high degree of accountability would presumably not support a waiver of liability. In other instances, shareholders might favor them in order to attract or retain qualified managers. Still others would presumably want a mix, allowing waiver but only in specified circumstances.Our analysis reveals that the diversity predicted by a private ordering model is not borne out by the evidence with waiver of liability provisions for Fortune 100 companies. All states permit such provisions and in the Fortune 100, all but one company has them. Moreover, they are remarkably similar in effect, waiving liability to the fullest extent permitted by law. In other words, one categorical rule was merely replaced by another, dealing a significant blow to the contractarian thesis.

Sturnus vulgaris, mitochondrial selection, MATLAB code and microsatellite data

Here we provide MATLAB code used to simulate drift and selection between and within individuals, which has been used to investigate mitochondrial haplotype frequency shifts in Sturnus vulgaris. Also provided is a microsatellite data set used to assess whether empirical allele frequency shifts were likely to be caused by admixture. These files support and upcoming publication, which concludes that within-individuals selection on mitochondrial DNA best explains empirical data.

CISR-ODE, A C plus plus framework with ODE solver for code based system dynamics simulation

Ordinary differential equations are used for modelling a wide range of dynamic systems. Even though there are many graphical software applications for this purpose, a fully customised solution for all problems is code-level programming of the model and solver. In this project, a free and open source C++ framework is designed to facilitate modelling in native code environment and fulfill the common simulation needs of control and many other engineering and science applications. The solvers of this project are obtained from ODEINT and specialised for Armadillo matrix library to provide an easy syntax and a fast execution. The solver code is minimised and its modification for users have become easier. There are several features added to the solvers such as controlling maximum step size, informing the solver about sudden input change and forcing custom times into the results and calling a custom method at these points. The comfort of the model designer, code readability, extendibility and model isolation have been considered in the structure of this framework. The application manages the output results, exporting and plotting them. Modifying the model has become more practical and a portion of corresponding codes are updated automatically. A set of libraries is provided for generation of output figures, matrix hashing, control system functions, profiling, etc. In this paper, an example of using this framework for a classical washout filter model is explained.

Victoria’s banning provisions: ‘balancing’ discretionary police powers and individual rights

This thesis examines the parliamentary passage, implementation and ongoing scrutiny of Victoria’s banning notice provisions. Underlying political assumptions and justifications are explored to reveal how banning notices exemplify a move towards police-imposed discretionary justice, which undermines individual rights and reconfigures the notion of balance in the criminal justice system.

Defence against code injection attacks

Code injection attacks are considered serious threats to the Internet users. In this type of attack the attacker injects malicious codes in the user programs to change or divert the execution flows. In this paper we explore the contemporary defence strategies against code injection attacks (CIAs) and underline their limitations. To overcome these limitations, we suggest a number of countermeasure mechanisms for protecting from CIAs. Our key idea relies on the multiplexing technique to preserve the exact return code to ensure the integrity of program execution trace of shell code. This technique also maintains a FIFO (first in first out) queue to defeat the conflict state when multiple caller method makes a call simultaneously. Finally, our technique can provide better performance, in terms of protection and speed, in some point compared to the CFI (control flow integrity) as well as CPM (code pointer masking) techniques.

Dip financing of financially distressed companies in Brazil – the conditions provided by the brazilian bankruptcy law act as real incentives for dip lenders as in chapter 11 of the American bankruptcy code?

O objeto deste trabalho é a compreensão do financiamento de empresas em crise, mais especificamente, o financiamento concedido após o pedido de recuperação judicial, como forma de permitir que a empresa saia da situação de crise e retorne à condição de normalidade. Para tanto, nos apropriando do termo cunhado pela doutrina norte-americana, para fazer referência ao aporte de recursos em empresas em dificuldade, utilizaremos o termo DIP financing ou financiamento DIP. Para uma compreensão adequada do objeto, é necessário que entendamos a origem do DIP financing nos Estados Unidos e como é a regulação norte-americana sobre a matéria atualmente. O segundo passo será avaliar a possibilidade de aplicação da mesma estrutura de aporte de recursos no Brasil. Ao estudarmos a origem desse mecanismo nos Estados Unidos, veremos os problemas que surgiram ao longo dos anos e como foram superados jurisprudencialmente e doutrinariamente para que o financiamento DIP se consolidasse como uma das formas de aporte de capital em empresas em crise, culminando no desenvolvimento de uma verdadeira indústria de crédito às empresas em dificuldade. Uma análise dos problemas enfrentados pelo sistema falimentar americano nos levará a hipótese de que, a menos que sejam afirmados mecanismos que assegurem a quem concede o financiamento após o pedido de recuperação judicial, uma super prioridade no recebimento após a recuperação judicial, será possível o desenvolvimento de um mercado de DIP financing no Brasil.

Apuração de haveres na sociedade limitada: uma análise crítica da jurisprudência

Esta dissertação tem por objetivo investigar a apuração de haveres nas sociedades limitadas a partir da análise da jurisprudência, notadamente para compreender o alcance da liberdade de contratar das partes, estabelecido, entre outras normas, no artigo 1.031 do Código Civil. Para tanto, analisaram-se os julgados do STJ, disponíveis no sítio eletrônico da corte e, da mesma forma, os do TJSP, dada a relevância econômica do estado e a existência de câmaras especializadas em direito empresarial, entre o período de 2010 a 2014. Tentou-se construir uma tipologia das questões que compõem o julgamento das cláusulas de apuração de haveres, como, por exemplo, distinção entre forma de apuração e forma de pagamento; e, igualmente, dos fundamentos usados pelos tribunais para afastar ou aplicar as cláusulas. Na segunda seção, fez-se uma análise crítica dos argumentos jurisprudenciais, sob a forma de defesa daqueles que, a nosso sentir, devem validar as cláusulas de apuração de haveres, quais sejam: boa-fé objetiva, função social e os constantes na literatura americana do capital lock in. Além disso, pontua-se sobre o emprego, a nosso sentir, inadequado do “enriquecimento sem causa”, como também da conveniência de se fazer uma aplicação ponderada dos princípios, especialmente quando contrariam uma regra jurídica positivada. Por fim, antes de concluir, comentou-se sobre a forma de apuração de haveres construída pela jurisprudência, a qual denomina-se, neste trabalho, dissolução total simulada.

A função social do contrato como concretização de direitos fundamentais nas relações privadas

This dissertation deals with the social function of the contract, based on constitutional principles, especially those relating to fundamental rights. The social function of the contract (general clause) is described in the Civil Code so intentionally generic, no precise criteria to define it. Because of the fluidity of this principle, it is justified its closer study, seeking to assess its various meanings and looking away from the legal uncertainty that an unlimited conceptual vagueness can cause. The social function of the contract arises from a transformation experienced in private law from the inflows received from the Constitutional Law, the result of an evolutionary process by which it became the state structure, leaving the foundations of the classical liberal state and moving toward a vision guided by existential human values that give the keynote of the Welfare State. Arose, then the concern about the effectiveness of fundamental rights in relations between individuals, which is studied from the inapplicability of fundamental rights in private relations (U.S. doctrine of State action), passing to the analysis of the Theory of indirect horizontal effect of fundamental rights (of German creation and majority acceptance), reaching the right horizontal efficacy Theory of fundamental rights, prevailing Brazilian doctrine and jurisprudence. It has also been investigated the foundations of the social contract, pointing out that, apart from the provisions of the constitutional legislation, that base the principle on screen, there have also been noticed foundations in the Federal Constitution, in devices like the art. 1, III, the dignity of the human person is the north of the relationship between contractors. Also art. 3rd, I CF/88 bases the vision of social covenants, equipping it for the implementation of social solidarity, as one of the fundamental objectives of the Republic. Still on art. 170 of the Constitution it is seen as a locus of reasoning in the social function of the contract, the maintenance of the economic order. It is also studied the internal and external aspects of the social function of the contract, being the first part the one that considers the requirement of respect for contractual loyalty, through the objective good faith, as a result of the dignity of the hirer may not be offended by the other through the contract. On the other hand, the external facet of the social function of the contract, in line with the constitutional mandate of solidarity, indicates the need for contractors to respect the rights of society, namely the diffuse, collective and individual third party. In this external appearance, it is also pointed the notion of external credit protection, addressing the duty of society to respect the contract. There has been shown some notions of the social contract in comparative law. Then, there has been investigated the content of principle study, through their interrelationships with other provisions of private and constitutional law, namely equality, objective good faith, private autonomy and dignity of the human person. We study the application of the social contract in contractual networks as well as the guidance of conservation of contracts, especially those denominated long-term captive contracts, considering the theory of substantive due performance, concluding with an analysis of the social contract in code of Consumer Protection

A simple mechanism to deal with sequential code in dataflow architectures

The aim of this work is to propose a simple and efficient mechanism to deal with the problem of executing sequential code in a pure dataflow machine. Our results is obtained with a simulator of Wolf [4] architecture. The implemented mechanism improved the architecture performance when executing sequential code and we expect that this improvement could be better if we use some heuristics to deal with some special groups of instructions such as branch operations. Further research will show us if this is true.

Spectroscopic characterization of SnO2 gels - Code: CP11

Excitation and dynamic emission spectra of Eu3+ ions were simultaneously used with FTIR and Raman spectroscopy to study the structural evolution during SnO2 sol → gel → xerogel conversion. Results make evident an increase of the surroundings symmetry for the Eu3+ ions dissolved in SnO2 matrix and a decrease of the amount of hydroxo groups (Sn-OH) during drying. These phenomena were associated to the pursuit of the condensation reaction after gelation. © 1994 Kluwer Academic Publishers.

ENCORE: Enhanced code Galileo receiver for land management applications in Brazil

Taking benefit of the new Galileo ranging signals, the ENCORE (Enhanced Code Galileo Receiver) project aims to develop a low-cost Land Management Application to cover needs of the Brazilian market in terms of geo-referencing and rural/urban cadastre, using a low-cost Enhanced Galileo Code Receiver as baseline. Land management applications require precision and accuracy levels from a few to several decimetres that are under-met with current pseudorange-based receiver and over-met with phase observations. This situation leads either to a waste of resources, or to lack of accuracy. In this project, it is proposed to fill this gap using the new possibilities of the Galileo ranging signals, in particular E5 AltBOC and E1 CBOC. This approach reduces the cost of the end-user solution, helping the rapid penetration of Galileo technology outside Europe. ©2010 IEEE.

Automatic code generation for microcontrollers from place-transition Petri net models

This paper describes a program for the automatic generation of code for Intel's 8051 microcontroller. The code is generated from a place-transition Petri net specification. Our goal is to minimize programming time. The code generated by our program has been observed to exactly match the net model. It has also been observed that no change is needed to be made to the generated code for its compilation to the target architecture. © 2011 IFAC.
