this paper seeks to investigate a new definition for architecture by unifying the three vitruvian principles of firmitas, utilities, and venustas via a phenomenological approach in the interpretation and analysis of their role in defining architecture. the paper is composed in two main sections. the first section investigates the nature of architecture based on the mentioned principles, where a...

This paper investigates the Multi-band OFDM (MB-OFDM) based physical (PHY) layer proposal for IEEE 802.15.3a working group on short-range high data-rate Ultra-wide-Band (UWB) communications. An overview of the MB-OFDM PHY layer architecture with its various parameters is presented and the optimal choice of critical parameters is discussed. Next, we derive the theoretical un-coded Bit Error Rate...

We describe an instance-based model of decision-making for repeated binary choice. The model provides an accurate account of existing data of aggregate choice probabilities and individual differences, as well as newly collected data on learning and choice interdependency. In particular, the model provides a general emergent account of the risk aversion effect that does not require any metacogni...

The paper discusses a choice of appropriate software architecture with regards to the specifications of embedded applications as information systems particularly used in area of radio and television broadcast audio program processing. The main requirement of mentioned embedded systems is an extremely good real-time response and minimized latency between input signal and output signal after proc...

this article presents a novel method and development paradigm that proposes a general template for an enterprise information structure and allows for the automatic generation and modification of enterprise workflows. this dynamically integrated workflow development approach utilises a conceptual ontology of domain processes and tasks, enterprise charts, and enterprise entities. it also suggests...

The loading problem is the problem to decide if a neural architecture can map a training set correctly with an appropriate choice of the weights. The following results will be shown: The loading problem is NP-complete for any feedforward perceptron architecture with at least two neurons in the rst hidden layer and varying input dimension. Further, it is NP-complete if the input dimension is xed...

his background paper explores the technical pathways by which states might acquire nuclear, chemical, and biological weapons and the systems to deliver them. It also assesses the level of effort, commitment, and resources required to mount such developments. The paper is a companion to the OTA report Proliferation of Weapons of Mass Destruction: Assessing the Risks, which describes what nuclear...

In this commentary, I focus on the deficiencies in the reflective-impulsive model (RIM) by Strack, Werth, and Deutsch (2006) in terms of understanding the mechanics of the reflective system. Strack et al. outlined the cognitive architecture of the consumer with the RIM but failed to specify how its most impressive feature, the reflective system, is powered. Drawing on the literature on self-reg...

This paper presents a web-based architecture for providing digital time stamping services. Time stamping services are typically divided into schemes which rely on unconditionally trusted Time Stamping Authorities (TSAs) and schemes which do not, namely the so called linking schemes. The proposed architecture relies on a multi-tier structure. The middle-tier exposes digital time stamping functio...
