Dissipativity and feedback passivity properties in nonlinear multiple-input multiple-output (MIMO) discrete-time systems are examined. Three main results are presented. First, necessary and sufficient conditions for the characterization of a class of dissipative nonlinear MIMO discrete-time systems in general form are proposed. The class of dissipativity treated is referred to as Quadratic Stor...

Images retrieval from a large database is an important and emerging search area. This retrieval requires the choice of a suitable set of image features, a method to extract them correctly, and a measure of the similarity between features that can be computed in real-time. This paper presents a complete set of Fourier-Mellin descriptors for object storage and retrieval. Our approach is translati...

Cases are descriptions of situations limited in time and space. The research reported here introduces a method for representation and reasoning with time-dependent situations, or temporal cases, within a knowledgeintensive CBR framework. Most current CBR methods deal with snapshot cases, descriptions of a world state at a single time stamp. In many timedependent situations, value sets at partic...

This paper proposes an automated approach for describing how geospatial objects evolve. We consider geospatial objects whose boundaries and properties change in the time, and refer to them as evolving objects. Our approach is to provide a set of rules that describe how objects change, referred to as rule-based evolution. We consider the case where we are given a series of snapshots, each of whi...

We consider the applicability of ID-based cryptography to providing security within a Personal Area Network (PAN). An initialisation process appropriate for use within a PAN is proposed, and a detailed comparison between the ID-based approach and a more conventional PKI approach is given.

Due to globalization and the growth of international trade, many container terminals are trying to improve performance in order to keep up with demand. One technology that has been proposed is the use of Automated Guided Vehicles (AGVs) in the handling of containers within terminals. Recently, a new generation of AGVs has been developed which makes use of cassettes that can be detached from the...

Saat ini, tata letak pada Gudang Material Kemasan dan Dus tidak memiliki cukup ruang untuk menampung seluruh material. Beberapa pallet material ditumpuk langsung tanpa adanya penyangga. Oleh sebab itu, perusahaan perlu melakukan perbaikan terkait gudang agar dapat memperbaiki permasalahan tersebut. Penelitian ini bertujuan dengan cara menata ulang sistem penempatan barang. Data yang digunakan m...
