Responding to the increasing complexity and diversity of information systems development, method engineering provides techniques and tools for the analysis, design, and evolution of information systems. Similar challenges can be found in the research area of enterprise architecture (EA) management, whose main goal is to enhance the alignment of business and IT. While a multitude of methods and ...

This article presents a deterministic model for sub-block-level population estimation based on the total building volumes derived from geographic information system (GIS) building data and three census blocklevel housing statistics. To assess the model, we generated artificial blocks by aggregating census block areas and calculating the respective housing statistics. We then applied the model t...

This study introductions situation of video storage and the methods of video data management, then proposes a Scheduling Strategy algorithm based on Offset Cache (SSOC). According to the statistical information of data block buffer offset, through building a cloud environment and studying the storage layer’s video data storage of the cloud storage, the algorithm schedules on mastering the suppl...

This paper deals with estimation of structured signals such as damped sinusoids, exponentials, polynomials, and their products from single channel data. It is shown that building tensors from this kind of data results in tensors with hidden block structure which can be recovered through the tensor diagonalization. The tensor diagonalization means multiplying tensors by several matrices along it...

A recent publication [l] introduced the concept of current conveying and an implementation in the form of a circuit building block termed the current conveyor (CC). This block has proven to be useful in many inst.rumentation applications, some of which have already been test)ed and reported [2], [3], while others are still under investigation. This correspondence introduces another new building...

An unprecedented 3D hetero-triple-walled metal-organic framework is obtained by straightforward elaboration of the mixed molecular building block (MBB) strategy. In this approach, multiple individual flexible and rigid MBBs are integrated into one composite building block as separate layers, which are of the same shape but different sizes. This MOF shows exceptional water stability and the appl...

We evaluate constructions for building pseudo-random functions (PRFs) from pseudo-random permutations (PRPs). We present two constructions: a slower construction which preserves the security of the PRP and a faster construction which has less security. One application of our construction is to build a wider block cipher given a block cipher as a building tool. We do not require any additional c...

An active set algorithm (ASA) for box constrained optimization is developed. The algorithm consists of a nonmonotone gradient projection step, an unconstrained optimization step, and a set of rules for branching between the two steps. Global convergence to a stationary point is established. For a nondegenerate stationary point, the algorithm eventually reduces to unconstrained optimization with...

This paper deals with the characterization of integrated circuits electromagnetic emissions. The TEM cell method is employed in order to identify primary emissions sources of complex digital devices. An 8-bit microcontroller, realized by a 0.8 m HCMOS process is considered. It is composed of several building blocks like the central processing unit, the analog to digital converter and the EPROM ...
